Description

[Detailed description of the invention] ``Purpose of the invention'' (Industrial application field) The present invention is capable of firmly holding workpieces such as faucet materials, and can quickly attach and detach the workpiece. It's about vice.

As shown in FIG. 8, the faucet device has a structure in which a round rod-shaped body 2, in which a valve mechanism, a temperature control mechanism, etc. are integrated, is inserted into the interior of a faucet body 1. In the inserted state, it is important that the outer surface of the round rod-shaped body 2 is in watertight contact with the inner surface of the faucet main body 1. Therefore, in the final stage of manufacturing the faucet body 1, high-precision machining using a boring machine, a milling machine, etc. is performed. Faucet appliances have different external shapes depending on the type, as seen in hot and cold water mixing faucets, etc.
When machining the faucet material, a vise of a special shape that matches the external shape of the faucet material is required. A conventional vise is shown in FIG.

(Conventional Vise) FIG. 7 is a side sectional view showing a conventional vise. Conventional vises are made of faucet material (indicated by a two-dot chain line.Hereinafter,
This is to hold a workpiece (referred to as a workpiece 1a) in a sideways state. The configuration of the conventional vise is that the workpiece 1
It consists of a work table 5 that receives a workpiece 1a, a pressurizing tool 6 that can come into contact with the upper surface of the workpiece 1a, and a top plate section 7 that raises and lowers the pressurizing tool 6. A male screw 6b with a handle 6a is pivotally attached to the upper part of the pressure tool 6.
The male screw 6b is screwed into a bracket 7a attached to the top plate 7, and the pressure tool 6 is moved up and down by rotating the handle 6a.

(Problems with Conventional Vise) As shown in FIG. 8, hot water supply pipes 3, a discharge pipe 4, etc. are connected to the faucet equipment. Therefore, the workpiece 1a is provided with a plurality of protruding portions that serve as connection portions with these tubes 3 and 4. In the conventional vise, the workpiece 1a is positioned by fitting the protrusion 1b into the workpiece table 5. For this reason, when trying to remove the workpiece 1a that is conventionally attached to a vise, the pressure tool 6
However, it was necessary to unscrew the handle 6a many times until it rose to a height equal to or greater than the length of the protrusion 1b.
The thread pitch of the male screw 6b that is pivotally attached to the pressure tool 6 is usually around 2 mm, so even if the length of the protrusion 1b of the workpiece 1a is only 20 mm, the handle 6b must be rotated at least 10 times. This means that you have to do it. Therefore, the work of attaching and detaching the workpiece 1a is extremely troublesome, and a great deal of time is wasted.

The present invention was developed in view of the above circumstances, and an object of the present invention is to provide a new vise that can quickly attach and detach a workpiece.

"Structure of the invention" (Means for solving the problem) The gist of the proposed vise is that it is used in a vise that securely holds a workpiece such as a faucet material between a work table and a pressurizing tool. , an intermediate member that holds a pressure tool so that it can be raised and lowered by screw fitting or the like and has a locking protrusion that projects in the radial direction at its lower end; and a top plate that guides the intermediate member so that it can be raised and lowered on the work table. and a through hole for the locking protrusion of the intermediate member is formed at one end side of the elongated hole for intermediate member insertion, which is provided so as to be slidable on the horizontal surface of the lower surface of the top plate and is bored along the sliding direction. It consists of a stopper plate and a riser that directly or indirectly lifts and urges the intermediate member toward the top plate.

(Function) The intermediate member is inserted into the long hole of the stopper plate. The intermediate member is urged upward toward the top plate portion by a riser. Therefore, the intermediate member is pressed against the stopper plate in a state in which the locking protrusion projecting in the radial direction is locked to the stopper plate. A pressure tool is attached to the intermediate member by screw fitting or the like, and since the pressure tool can be adjusted up and down, it is possible to press the pressure tool against the workpiece on the work table. can be lowered to On the other hand, when the stopper plate is slid, the through hole formed at one end of the elongated hole in the stopper plate matches the locking protrusion of the intermediate member. Therefore, the intermediate member passes through the stopper plate and rises all at once due to the lifting force of the riser. Since the pressurizing tool rises together with the intermediate member, the workpiece on the work table can be easily removed.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a perspective view showing the proposed vise, and the second
The figure is a side sectional view. As shown in FIG.
It consists of a top plate part 7, a stopper plate 9, and a riser 10. The main part of the present invention is the connection relationship between the intermediate member 8 and the stopper plate 9 and the direct or indirect connection relationship between the intermediate member 8 and the riser 10.

The intermediate member 8 is inserted through the top plate portion 7 so as to be freely movable up and down. The intermediate member 8 has a substantially cylindrical outer shape, and is provided with a flange-like locking protrusion 8a that protrudes in the radial direction around the entire lower end thereof. Intermediate member 8
A female screw is carved in the cylindrical hole of the pressurizing tool 6.
It is in a threaded relationship with a male screw 6a with a handle 6a attached to the upper part of the handle. The insertion relationship between the intermediate member 8 and the top plate portion 7 is such that, as shown in a plan view in FIG. In FIG. 2, reference numeral 12 indicates a fixed cap for the parallel key 11 (omitted in FIG. 4). The fixed cap 12 is filled with grease that smoothes the vertical movement of the intermediate member 8 with respect to the top plate 7, and also serves to prevent chips and the like from entering. The guide means for moving the intermediate member 8 up and down with respect to the top plate 7 is the parallel key 1 as described above.
It is not limited to the one using 1, but it is also possible to use serrations, splines, etc.

The stopper plate 9 is provided so as to be slidable along the horizontal plane of the lower surface of the top plate portion 7. FIG. 5 is a side view of the stopper plate 9, and FIG. 6 is a bottom view. As shown in FIG. 6, a long hole 9a through which the intermediate member 8 is inserted is bored in the center of the stopper plate 9. The groove width of the elongated hole 9a is slightly larger than the outer diameter of the cylinder of the intermediate member 8, so as not to impede the movement of the intermediate member 8 up and down with respect to the top plate portion 9. A large diameter through hole 9b is provided at one end of the elongated hole 9a.
are formed continuously. The diameter of the through hole 9b is made larger than the collar-like locking protrusion 8a of the intermediate member 8. In addition, the through hole 9 of the elongated hole 9a
The peripheral portion of the end opposite to b is formed thick as shown in FIG. The thick portion 9c serves as a spacer that ensures and adjusts the vertical stroke of the intermediate member 8. That is, since the overall thickness of the stopper plate 9 including the thickness of the thick portion 9c is the lifting distance of the intermediate member, this total thickness is determined by the protrusion of the workpiece 1a fitted into the work table 5. The length may be made larger than the length of the portion 1b. Furthermore, on the front edge of the stopper plate 9 (the left edge in FIGS. 5 and 6),
A handle 9d for operating the drawer is bent.
The sliding movement of the stopper plate 9 is guided by L-shaped tracks 13, 13 as shown in FIG.

As shown in FIG. 1, the riser 10 is configured to lift and bias a handle 6a pivotally attached to the pressure tool 6 upward. As shown in FIG. 2, the riser 10 includes a lifting claw 10b attached to the upper end of a lifting shaft 10a, and a coil spring 14 inserted through the lifting shaft 10a. The lifting claw tool 1
0b has a forked front end and is adapted to come into contact with the lower surface of the handle 6a of the pressurizing tool 6. Moreover, the lifting claw tool 10b includes:
The knock pin 15 hangs down and prevents the pressurizing tool 6 from rotating.

The usage situation of the device thus constructed according to the present invention will be explained. First, as shown in FIG. 2, it is assumed that the workpiece 1a is already held and fixed in the vise of the present invention. To remove the workpiece 1a, first unscrew the handle 6a of the pressurizing tool 6 by about half a turn to one turn. Then, place the stopper plate 9 on the front side (left side in the drawing).
Pull it out. As a result, the through hole 9b (see FIG. 6) of the long hole 9a in the stopper plate 9 can be
It matches the locking protrusion 8 of the intermediate member 8. Therefore, the third
As shown in the figure, the intermediate member 8 is attached to the handle 6 of the pressurizing tool 6.
It will be raised all at once by the riser 10 via the male screw 6b and the male screw 6b. Therefore, the workpiece 1a on the worktable 5 can be taken out. On the other hand, when holding and fixing the workpiece 1a, the order is almost reverse to that described above. That is, the workpiece 1a is placed on the work table 5, and the handle 6a is pulled down to the extent that the pressure tool 6 comes into contact with the workpiece 1a. In this state, the stopper plate 9 may be pushed in and the handle 6a may be further tightened by about half a turn to one turn.

(Study of Alternative Embodiments) The workpiece is not limited to faucet material, and the presence or absence of protrusions is also not limited. Therefore, it is possible to make the pressurizing tool and the work table smooth so that the surfaces that come into contact with the workpiece are of a general-purpose type. In this way, the configuration and shape of the present vice can be changed as appropriate depending on the mode of implementation.

"Effects of the Invention" As is clear from the above explanation, the vise according to the present invention, which is capable of quickly attaching and detaching the workpiece, allows the workpiece to be attached and detached extremely easily and quickly. Work efficiency will be greatly improved. Also,
Compared to conventional vises, the force required to attach and remove the workpiece is reduced, making it easier for female workers to handle, and it also holds and secures the workpiece firmly and reliably. It has many excellent advantages.
