Description of the Invention (/) The present invention relates to a short rod feeder for a machine tool such as a rotary lathe or an automatic lathe. A plurality of clamping elements, configured parallel to each other and aligned to support a plurality of rods arranged on an inclined plane, and a loading slider-a device for centering the rods relative to the machine tool according to the alignment axis, and A device for advancing the rod in the machine tool. The purpose of these feeders is to automatically feed the rod, especially to an automatic lathe, so that the productivity of these machines can be significantly improved and the machine tool can be considerably reduced. The cost of the artifacts of the mechanism. The term "rod" as used in this patent application encompasses prismatic elliptical workpieces of any material, including tubes, which are much longer than their diameter. The conventional feeder and its function will not be described in detail below. Generally, the feeder includes a frame, an inclined plane-shaped rod box mounted thereon, a loader, which takes a rod to be processed from the box, centers it horizontally and lifts it, and a vertical centering device The rod is coaxially aligned with the mandrel of the relevant lathe, and a pushing device pushes the rod into the mandrel. However, the conventional feeder has several disadvantages. First, this disadvantage is the most serious. During the loading process, because the device is subjected to two consecutive impacts, the loading operation is performed in a rough way: the first impact is when a rod to be loaded is replaced by a series of The parallel gripping fingers support the one caused by falling into the loader during a rising movement in the box. The rising movement is necessary for the rod to be conveyed from a lower level to a box level. Level to the axis of the mandrel. This vibration is particularly strong and noisy, and can damage some parts of the feeder.

Invention Description (>) Reminder, a single steel rod with a diameter of 80mm and a length of 1200mm The weight is about 47 kg; these impacts may eventually lead to deviations between the feeder and the machine tool headstock, posing serious risks for both the feeder and the machine tool. The second shock is caused when a shot has been taken from the cassette and taken away by the loader: the next shot, which is placed in the tilted plane of the cassette, will then bear against the gripping finger. Although this impact is not dangerous for the feeder, it is not unpleasant to the ears and it generates vibrations that may cause the feeder to deviate from the machine. The object of the invention is to create a new feeder which reduces these difficulties and allows a further increase in efficiency by means of a push automation. This object is achieved by a feeder according to the invention, characterized in that the clamping elements in the loading device are a plurality of clamping fingers, which are arranged parallel and aligned with each other, the shape of these fingers and The position is such that when these loading sliders perform their vertical ascent, the fingers continue to hold a rod supported by the loading slider in such a way that during the loading of the rod, the rod and the carrier carried by the two A mother body is each seated more or less in contact with the clamping finger on the loading slide until the rod has reached its final position in the alignment axis, ie, its highest position. This feeder with better or special characteristics forms the subject of the scope of the patent application. The following description of an embodiment of a feeder according to the present invention is provided for a better understanding of the present invention; this example is non-limiting.

Figure 1 shows a plan view of a preferred embodiment of a feeder according to the present invention; the rod box is not shown for the sake of removal; a machine base 10 can be seen, which serves as a support and housing for the different elements of the feeder . A flat 14-shaped box 12 'is inclined at an angle α with respect to a horizontal plane, and is mounted on a horizontal angular section 16 by a hinge 18 (Figures 2 and 3). Therefore, the inclination of the plane 14 is adjustable. A bed 20 including an elliptical contour section 22 supports a rail 24 on which a slide plate 26 can be moved to push the lever horizontally in the tool headstock. The work and functions of this slide are conventional and will not be described in detail. In addition, the bed 20 is provided with a plurality of loading slides 28, which are plate-shaped, are vertically installed in the bed and are fixed by a welded horizontal plate 29, and have a gripping point 30 and two stoppers 30A, 30B ( (Figure 6A), which forms a large ν shape, which is open upwards and has an angle of / 3, usually about 1 20 °, that is, a rod used to receive a circular or hexagonal cross section. (Please read the precautions on the back before filling this page) Load the slides 2 8 The V-shaped vertices are located in the vertical axis Z passing through the center C of the tool head base related to the feeder (see section 6AA and 6D). The bed 20 can be moved in the vertical direction by two hydraulic or pneumatic jacks 32 (see Figures 1, 2 and 4). The bed is then guided by a slider 34 that slides in the vertical rail 36 (Fig. 4). This paper uses the Chinese National Standard (CNS) A4 (210 X 297 mm) printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 496802 A7 B7 V. Description of the invention (4) A shaft 38 is housed in the bearing 40 of the base 10. A series of very long-shaped clamping fingers 42-aligned and snapped onto the shaft 38 by a ring 44 (see Figures 1 and 3). The finger 42 has two active surfaces (or edges), a lower surface 42A and an upper surface 42B (Figures 3 and 6D), and its functions will be described in detail with reference to Figures 6A to 6D. A guide hole 46 is made in the finger 42 and serves as a path for the control finger 42 to be inclined with respect to the vertical direction, and attempts to receive a control pin 48 (FIG. 5). As seen in Figures 2 and 3, this hole 46 is not straight, but is curved. The purpose and function of this hole will be described in more detail below. The two middle fingers 42 are fastened at a small distance by the corresponding fixing members (see Fig. 5), wherein the two fingers 42 ', 42' 'are connected by the distance sleeve 50, and the fixing elements thereof are not shown. In Fig. 6, the reference number of the highest point of the finger 42 is 42C. As shown above, the bed 20 performs a vertical movement to obtain a rod to be processed from the cassette 12. Reference will be made to Figures 6A to 6D, which schematically show the cycle of loading one shot 60. Prior to the start of the loading cycle, the bed 20 is parked in its lowest position, as shown in Figures 2, 3 and 6A. Then, the bed 20 starts to rise vertically, and the point 30 loaded with the slider 28 is completely integrated with the bed 20 and slides between the lever 60 supported by the finger 42 and the second lever 62 (FIG. 6B) . It may be noted that the plane 14 of the cassette 12 contains a slot or other opening 14A to allow passage of the slider 28. As can be seen in Fig. 6B, the lever 60 is always supported by the finger 42. In this case, the lever 60 is supported by its face 42B, and the lever 60 cannot roll along the edge 30A of the slider 28. During the continuous rising of the slider 28 (see Fig. 6C), the rod always applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) with the second mother paper size ---------- ---------- Order --------- line (please read the precautions on the back before filling this page) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 496802 A7 B7 V. Invention Explanation (i) In the first aspect, the surface 30A of the slider 28 and the surface 42B of the gripping finger 42 are in rolling or sliding contact. It can be seen that the lever 60 performs the upward movement and the left movement simultaneously, that is, from the box 12 to the left until it enters the Z axis. Finally, although the loading slide 28 always rises continuously, the rod 60 is located at a distance of 30B from the edge, 42C from the tip 42C of the finger 42, and a few millimeters from the loading axis C of the feeder (see FIG. 6D), And the effect of the last few millimeters of ascending is to make the rod 60 bear against the second edge 30B while maintaining contact with the edge 30A 'and finally in the axis C. The result is an absolutely quiet movement of one of the rods 60 from its point of acquisition at the cassette 12 to its point of alignment with the long axis C of the feeder and the machine tool to be fed. The achievement of this gentle and quiet movement, according to the invention, is due to the phenomenon that the rod is always supported by the two parents. When the feeder must work with rods of other diameters, the support point of the rod relative to the clamping finger must be changed. This is because the axis of the rod R is obtained, which is the upper extension of the vertical edge 28B behind the slider 28. -Must be absolutely located between two continuous rods in the box, ie this axis R must form a common vertical tangent to the two continuous rods. See FIG. 6A. One of the larger diameter rods 64 is shown as a break line. In the case of a larger rod diameter, the highest position of the bed must be changed, i.e. lowered, so that the rod, compared to a smaller diameter rod, is located at a greater distance from its surface than the axis Quasi-C axis. This highest position of the bed is determined by the stopper 66 (Figures 1 and 4), which is fixed to a nut (not shown) that can be moved along an endless screw (not shown), which is accommodated in a cylindrical and vertical In the sleeve 68; the connection between the stopper 66 and the nut is based on the Chinese paper standard (CNS) A4 (210 X 297 mm). ------------- ------- Order --------- line (please read the precautions on the back before filling this page) Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 496802 A7 B7 V. Description of the invention (A ) Through the longitudinal hole 69 of the sleeve 68. The endless screw rotating in the sleeve 68 is driven by a motor 70 (Fig. 3), which transmits its rotation via a chain 72 to a gear 74 fixed to the lower end of the endless screw. When the rod 64 having a diameter larger than the rod 60 is loaded, the 'motor 70 is started, and its rotation transmitted to the endless screw causes the two stoppers 66 to descend simultaneously. The stroke of the bed 20 thus becomes slightly shorter, while the stop surface 76 of the bed contacts the stop 66 slightly faster. By turning the motor in the desired direction, the operator of the feeder will adjust the stroke of the bed 20 so that the center of the (new) lever 64 coincides with the C feed axis. However, this adjustment is not sufficient because the clamp The inclination of the fingers 42 must still be adapted to the new diameter-a diameter of a thicker rod 64-to complete the situation with regard to the tangent line R described above (section 6A). In this case, the inclination of the finger 42 must be increased with respect to the vertical direction. According to the present invention, this adaptation to the new diameter is done automatically when the height position of the stopper 66 changes. For this purpose, an adjustment device (Figures 3, 4, and 5) is provided, which includes a vertical rod 78 _ arranged approximately between two stoppers 66 and through a corner section 80, a fine adjustment screw 82 and a The setting block 84 functions to be fixed to one of the stoppers 66. The control lever 78 is guided in the bed 20 by the two guide bushes 86, and the lever 78 extends upward until it is between the two intermediate clamping fingers 42 ', 42' 'closed together (Fig. 5). One or more of the control pins 48 mentioned above pass through the lever 78, and both sides enter the two guide holes 46 for holding the fingers. When the vertical position of the stopper 66 changes, for example, downward to adjust the feeder to a thicker rod, the control lever 78 follows this change. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297).

Description of the invention (7) and the same decrease; then, the pin 48 moves the finger 42 by moving the control hole 46 at the same time. under. The two fingers 42 ', 42' ', which are integrated with the shaft 38, rotate the shaft accommodated in the bearing 40, and all the clamping fingers are brought to a lower angular position-see section 6A Figure, where the new position of the finger 42 is represented by the break line. The position, shape, and length of the control hole 46 have been calculated by a computer, so that the joint movement of the stopper 66, the lever 78, and the finger 42 always results in the state for obtaining a lever shown in FIG. 6, that is, The angular position of the fingers 42 with respect to a rod 60, 64 and the position of the rod with respect to the vertical direction R. Needless to say, the characteristics of the hole 46 can also be obtained through many attempts without resorting to a computer. In this example, the structure of the feeder has adapted itself to a short rod, that is, a length of about 1600 mm and a diameter of 6 to 120 mm. The feeder according to the present invention can also be used to feed a non-circular cross-section rod to a machine tool, for example, square, hexagonal, octagonal, and the like. The only changes that may be required are the adaptation of the V-shaped loading slide (corner stone) and the tilt of the tilted plane of the box (angle α). These two changes can be achieved fairly simply and quickly. The feeder according to the present invention conveys the rods from the cassette 12 until they enter the machine tool axis C without impact, thereby avoiding the loss of adjustment and damage to the structure of the machine itself. Once between phases 6D and 6A, that is, during the continuation of the loading cycle, the impact of the rod holding the finger can be selected to be as small as possible by selecting an angle α of the inclined plane 14, usually about 5 ° while greatly reducing. Generally, the angle α is selected as a function of the diameter or the entire rod; for this paper size, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applied ----------------- --- Order --------- line ^^ (Please read the notes on the back before filling out this page) Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 496802 A7 B7 For rods with a diameter of approximately 3.5 °, for rods with small volume and diameter and for rods with a hexagonal section, it is approximately 15 °. In any case, this second impact is essentially smaller than the impact of a lever on the V-shaped clamping stop of the load slide of the prior art feeder, and it can be provided by the brake on the inclined plane 14-itself For the sake of habit one, the feeder that has been described by way of example is not limited by this description. It can be modified within the scope of this patent application based on the knowledge of a person skilled in the art; these modifications are, for example, the choice of materials. The vertical adjustment device of the pneumatic or hydraulic cylinder 32 and the stopper 66 may be replaced by other conventional motor devices or the like. In addition, the device does not need to adjust the inclination of the clamping fingers to be fixed to one of the stops 66; it can also be independently actuated by one of the endless screws rotating in the sleeve 68, or it can have its own The driver is preferably coupled to the chain 72. In any case, it is sufficient that the clamping fingers are coupled to the device to adjust the final height of the loading slider. In summary, the construction of the feeder described above avoids any impact of the rod on the loading slider and makes the machine more efficient in semi-automatically adapting to the variable diameter of the rod to be loaded.
