Description

[Detailed description of the invention] Fixed socket wrench drive device Screw tightening including ratchet drives and commonly used hexagonal nut and bolt heads Socket wrenches with standard sockets for driving fasteners are used in the field of machinists. and is commonly used. A machinist can turn the drive ratchet handle. When faced with the need to drive fasteners located in confined spaces, An extension drive is used to transfer the force from the chet to the socket. separated When driving fasteners in position, especially when working in narrow and obstructed areas. There should be a mechanism to secure the socket to the extension if this has to be done inside the is desirable. In addition to desirable fastening features, fasteners of various sizes can be It is necessary to be able to quickly exchange sockets for operation. machinist working The environment, for example when repairing a motor vehicle or mechanical equipment, the mechanic must Corroded or damaged fasteners, oil spills where positive fastening and release characteristics are desired. In addition to the conditions of the Sometimes. Under these circumstances, any mechanism is not only durable but also simple. It is highly reliable and provides an ineffective means of improving the efficiency of manual labor. Other requirements for a machinist's tools include the desire to make them relatively easy to manufacture and maintain. It's about getting.

There are various ways in which fastener drive sockets can be secured to the mechanisms that drive them. Are known. For most devices, it is important to ensure that the sogenod is attached to the drive device. It is important to use special features such as impact wrenches that provide a secure mechanism to secure the tool. It includes methods developed in response to specific requirements. In such a method, the driving Since the mechanism is relatively large and bulky to provide sufficient strength, it can be used widely. Even though the inside was machined, complex machining was possible. In addition, that All of these mechanisms are designed for use in areas where workers are provided with sufficient work space. Since the mechanism was small, the small size of the mechanism was not an important factor. known mechanism are equipped with fixing means such as external rotating collars, but friction with obstacles may cause improper (It is equipped with a plunger as a mechanism, but it does not use a separating device.) (Beer Patent No. 2,954,932: Wendling No. 2,987.334), other locking mechanisms include locking screws, pins or fasteners or uses a cumbersome release mechanism that requires removal of the socket from the workpiece. Therefore, it is not possible to quickly release the socket of a workpiece located in a narrow area (tricks). Mann Patent No. 2,677°562).

Another known mechanism according to certain applications similar to the mechanism of this invention is a ratchet socket. The cut drive unit is released with a push button. This mechanism requires relatively complicated machining. This invention differs from this invention in that it requires a Solid axial hole and press button may not work properly due to dust or wear. For use with extensions, use without threads, crucially, this Both applications also require downward pressure to be applied to the pushbutton plunger. At the same time, this force requires a resistance to the push button. acts in addition to a similar movement of the socket in the same direction as the resistance and in the opposite direction as the resistance. This is a movement that is difficult for a machine tanker working in a small space to handle. Ratchet with push button Relief also requires greater machining to achieve the same strength as non-machined parts. Since it needs to be made from one piece, it is the only one that can be ratcheted in a small space.7. Assemble the port and socket. It is often difficult to use them together (Smayer Patent No. 3.762.2). No. 45) This invention is smaller than the Kui-r free release style lacente handle, which is difficult to draw. As a complement to a strong ratchet, it takes advantage of the features of a fixed part and quick release. This is what I used.

Use 17x yourself. , these improved electric examples! f: L1 multiple elements cooperate Works 1 to 7 "C1 乍迢j1゜page, the application and patent of inventor Yoda ■ There are two ways to achieve additional objectives: The first improvement is a series of glue rolls 0. l,,,mu engagement Cca w+m1nq) and the related so/r throat with an adjustment rod to effectively fix the gutter. Using a new cam-engaging adjustment rod that provides a wedge effect between the ball and the It's in the middle of the day. The second improvement is to place a spring that cooperates with the retainer pole. Fixed Su! ! - In the event of an accidental release of the switch, the associated socket will be lost. It is a "C' thing" to prevent this from happening. Fixed-back (loek-back) machine for easy installation of tools In a fourth embodiment, using an extended shank and a separate structure, 1. hand The fixed part is used. In the fifth embodiment, an adjustment rod with a notch is used. This means semi-automatic reversing.

The advantage of using a cam-engaging adjustment rod is that the force applied to the retainer is It is to increase with. Other advantages are Soge 1.・The retention of the recessed part of the This is less important than in previous embodiments.

The advantage of using cooperating springs on the retainer poles is that some of the increased friction is 1. provided between the drive extension and the socket wall, even in the released position. It is.

The advantage of embodiments using fixed-back mechanisms and notch adjustment studs is that both It is somewhat of a semi-automatic operation.

Light milk amount! According to the invention, the socket wrench drive extension has a ratchet! -Driving handle and For use in conjunction with standard sockets to drive screw-threaded fasteners. It was designed to The extension part is one surface of the rectangular drive part of the socket. Extends beyond the shoulder machined into and separating the extended and driven parts of the device . , equipped with a longitudinal adjustment rod groove. Equipped with an adjustment rod, it is machined The adjusting rod is slidably mounted in a groove and moves longitudinally therein. adjustment rod The lower end is, in this example, made into an angle of approximately 15' to 30' relative to the green. tone The straightening rod has a sloped portion or a flat portion adjacent to the sloped portion. This example The slanted or sloped portion is located at the highest point of the adjustment rod when the adjustment rod is displaced sufficiently forward or downward. Longitudinal dimensions such that the lower end part does not touch the lowermost end of the extension drive part and the upper edge of the sloping part of the adjustment rod is completely displaced forward or backward. Surpassing with respect to bearing means for transmitting lateral forces by the straightening rod to the detents , and then maintains the socket in a fixed position unless released. Is the adjustment rod complete? When it protrudes all the way forward, the flat part of the adjustment rod comes into contact with the fixed ball bearing 1. This keeps the detent in place against the socket wall where the retainer groove is machined. Fixed in position.

A detent or retainer ball is slidably carried within a lateral hole in the drive portion of the extension. of the extension when in a fixed position relative to the fixed bearing pole and adjustment rod. A detent that extends beyond the surface of the rectangular drive part to the opposite surface where the adjustment rod groove is machined. Apply a lateral force to the force. The lateral protrusion of this detent Fits standard recesses in the drive wall of the socket, below or in front of the socket. prevent movement to. The outer protrusion of the detent further connects the socket to the drive shaft of the extension. Fixed in a predetermined position in relation to the line, driving the y-stop and the socket in the fixed position A lateral pressure is exerted on the drive wall of the socket by means of adjustment rods along opposite sides of the wall.

The longitudinal movement of the adjustment rod from the fixed position to the released position is due to the backward movement of the sleeve. brought about by The rearward force is directed away from the drive part of the extension slightly above the extension. The slidable collar installed in transmitted to. The backward movement of a slidably mounted collar is The extension also wraps itself around the body of the helical spring against the forward spring pressure. , by moving its collar backwards.

The mechanism exerts forward or downward pressure on the release collar and releases a circular clip or It is held in its fixed position by a spring fixed to the front extension using a clamp. It will be done.

Another embodiment uses the apparatus described herein to drive the socket 1/ner drive shank. This is a modification example in which fixing and releasing operations are performed at both ends of the moving end and the driving end. In this example In this case, the sliding collar extends rearward and is fixed to the surface of the shank, forming an approximately L-shape. restricted forward and backward movement across slots formed in the shape of a Supported so that it can slide freely against the outer shape of the driven part where the bin that allows rotational movement is arranged. The dimensions shall be sufficient for

Another variation of the sleeve including this embodiment is 2. Beyond the driven end surface of the shank. The inner surface of the sleeve has a plurality of grooves or holes extending backwards. Place the sign you owe. These recesses are arranged at the driven end or of the tenor ball. enable retreat. These recesses are driven by rotation and backward movement of the sleeve. One or more of the ends are shaped in a direction that exerts inward pressure on the retainer ball.

One driven end glue retainer ball is typically fitted with a ratchet wrench or other equivalent drive. By arranging the retainer ball to press against the drive end of the power tool, the system of this invention The jank is fixed in relation to it.

Using this embodiment, the device simply attaches to the end of the constant length extension. the device functions more as an adapter than with a release In this way, the feature of rapid release and fixation can be improved by mechanics.

FIG. 13 is an exploded view of the device with parts disassembled.

Assembly and disassembly are normally performed by removing the retainer bins 4 and 3.

Figure 14 shows the driven part 11, the extension part 797, and the rectangular driving part. 12 represents the socket fixation extension. The drive part 12 fits into the socket 21 combined to give rotational motion.

The shank 9 terminates in a shoulder 27 at the end of the shank 9. The slot or groove 10 is It is formed on the surface of the cank and extends to one face or wall of the drive part 11.

An adjustment bar 14 having an outer surface 13 is carried within the adjustment rod groove. The raised portion or claw 16 is It protrudes outward from its outer surface 13 and has a sleeve 15 (fitting 5"). For example, the internal curve 1 has a circular engagement element or a flange 4.

In this example, niobium, In most cases, it is preferable that the angle of the bevel be about ]O@, so that the socket gap and retention can be improved. The tip of the 7-inch straightening rod should also be a slope 51 adjacent to the outer surface 13. This figure shows the coil being compressed by engaging the outwardly protruding pawl on the adjustment rod to allow retraction. Sleeve-adjustment rod engagement element 2 that applies forward (leftward) force by the action of spring 1; 8 and 29 are further clarified. As explained in connection with FIG. and radially outward movement is provided by a C-clip fitted snubbed into slot 96 in the shank. However, other suitable configurations may be used.

As shown in FIG. 28 and opposing edges of the restriction collar.

The restriction collar itself is carried on the shank, with the inner surface of the shank surface having a reduced diameter. 56. The end of the restriction collar 57 has a surface 5 with a reduced diameter of the shaft. 6 and the outer surface engages a shoulder 58 formed at t'. Furthermore, the restricted colors are formed on the outer periphery of the sleeve 15 to engage the rear end 53 at the most retracted position. It includes a mating outwardly projecting shoulder 54. On the other hand, if this is the case, you will be able to move back from adjustment 14. Due to the movement of the slope 25, the retainer balls 22 and 24 are moved from the top surface 31 of the bottom surface 7. Allow for deviations.

As shown in FIG. 18, the movable distance is the adjustment rod 51 with the slope 25 on the inside. It is shorter than the distance between the points that form the straight rod surface 50. Such an arrangement allows a fixed position In this case, the retainer pole 22 remains engaged with the ramp 25. This means that the adjustment The forward movement of the rod and the backward movement of the adjustment rod are caused by engagement between the plane and the retainer pole. This point can be compared with Akira's patent No. 4,480.511.

As shown in Figure 17, this arrangement has several advantages.

In an environment where tools and standardized sockets of predetermined dimensions and clearances are used. The socket is often slanted, erected, and The state becomes unaligned. As a result, the tool gets caught and it becomes difficult to release the socket.

The retainer pole 2 cooperates with the socket engagement retainer ball 24 in contact with the slope 25. 2 engagement reduces the tendency to jam. Even a slight retraction of the adjustment rod 13 will result in adjustment. When the outer surface of the retainer and the outermost point of the retainer of the retainer 24, the lateral dimension is necessarily determined. 7. Reduces lateral pressure across the tool. Increases easy release. This allows the use of tools with smaller gaps, so each combo Rotation and tightening of the /t makes it possible to improve the gripping force due to the cooperation of forces. The lever pole 24 that engages with the outer surface 13 of the adjustment rod facing the wall is located at the front. When the retainer pole 24 is pulled in the left direction, the friction with the wall that engages with the retainer pole 24 Apply clockwise rotation as indicated by the arrow in the figure. Near the contact point (by shifting the bows) row (consider the condition), near diametrically opposed points of the retainer poles ? 4 engages with another ball 22. 240 revolutions of the first ball The ball 22 is given counterclockwise rotation as shown by the arrow. Also, the lateral force is It is transmitted to the slope or wedge edge of the adjustment rod, and is shown by the arrow on the adjustment rod. When the movement to the left is 4 strokes, there is a movement toward the left. This movement of the rod due to its configuration as a slope This ensures tight engagement between the retainer pole 24 and the surface of the adjustment rod. therefore, The rod is tightened between the ball 22 and the socut wall. The facing surface 31 is Provides a strong friction fit and resists each time a fixed tool is removed from the socket. do.

As a result, the retainer housing mentioned in the prior art and the inventor's previous invention 5. This makes it possible to use a socket that does not have a recess on the inner wall that engages with the handle 24. In the field, this means that sockets are subject to wear and that there are recesses in the inner wall 31. It is now possible to manufacture sockets that do not have any impact sockets, and Manufacture sockets with recesses or uniform structures, although not all walls Because it can be done, it increases its usefulness.

In this latter example, a lateral If the facing holes are aligned with the retainer mechanism - the glue that should engage the four parts - the rod simply engages the socket.

This is a problem in the field, and with this improved form, Even if the flat wall engages the retainer ball 24 and the outer surface of the adjustment rod 13, the The socket can be fixed.
