JPS5841094Y2 - Vise with elasticity in tightening force - Google Patents

Description

[Detailed explanation of the invention] A conventional vise has a structure in which a male tightening screw attached to a movable body is screwed together with a female tightening screw on the main body, and a bundle is provided at the tip of the male tightening screw, which connects the main body and the movable body. A steel base is provided at the top,
An object was clamped between the caps and the tightening male screw was rotated to clamp the gap between the caps and crimp the object.

For this reason, as the tightening male screw rotates, pressure is rapidly applied to the cap as it progresses, and there is a problem that objects with low elasticity limits, such as glass and corrugated plates, can be quickly retroactively deformed and destroyed. If the shape has a small contact area with the object to be held, such as a cylindrical object or an object with protrusions, the load will be concentrated at that point, resulting in damage and deformation of the object or the cap.

In order to solve these problems, it may be possible to attach an elastic body (buffer) to the surface of the cap, but the elastic body itself causes uneven deformation (pressurized state) when the object is bent, etc. However, there are problems in that the object to be held cannot be bent accurately and the elastic body is easily damaged by the object to be held.

The present invention aims to provide a vise that eliminates these drawbacks and problems and has a practical tightening force and elasticity.

The gist of this invention is that a male tightening screw 4 attached to a movable body 3 is screwed into a female tightening screw 2 provided on the side of the main body 1, and in a vise with a bundle 5 provided at the tip of the male tightening screw, the male tightening screw is 4
The vise is characterized by having a required elastic body 6 interposed between the body 1 and the movable body 3 or between the main body 1 and the female tightening screw 2, and has elasticity in tightening force.

Examples of the elastic body include elastic synthetic resin, rubber, and metal springs.

This will be explained below using examples.

First Embodiment (See FIG. 1) The first embodiment shown in FIG. 1 is an example in which an annular elastic body 6 is interposed between a male tightening screw 4 and a female tightening screw 2.

In the figure, 1 is the main body, 2 is a female tightening screw, 3 is a movable body, 4 is a male tightening screw, 5 is a bundle, 6 is an elastic body, 7 and 7' are bases,
8 is a screwing tube, 9 is a stopper hole provided in the screwing tube, 10
is a stopper.

In this embodiment, if the bundle 5 is turned by hand to rotate the tightening male screw 4, the screw tube 8 screwed into the tightening male screw 4 will not rotate due to its engagement with the stopper hole 9 of the stopper 10, so the tightening will be tightened. The attached male screw 4 itself moves forward and backward in the direction of the main body 1.

If the four tightening male screws are sent in one direction, the cap 7. The gap T' is sandwiched between the caps and the clamped object inserted between the caps 7 and 77 comes into contact.

Since the object to be clamped is generally a rigid body such as a metal plate, glass, or plastic, the elastic body 6 is compressed as the tightening male screw 4 advances, and the ferrules 7 and 7' are compressed according to the deformation of the elastic body. The pressure will gradually increase.

Therefore, the pressure applied to the object by the caps 7, 7' changes gradually from 0 to the elastic limit of the elastic body 6, and can be adjusted to appropriate pressure levels.

Therefore, it prevents the clamped object from being pressurized more than necessary or the occurrence of concentrated stress, and eliminates damage and breakage of the clamped object.
In addition, appropriate vise work can be performed.

Second Embodiment (See FIG. 2) The second embodiment shown in FIG. 2 is an example in which an elastic body 6 is interposed between the tightening screw 4 and the movable body 3.

The rest is the same as in the first embodiment, except that the movement of the screw tube 8, the stopper hole 9, and the stopper 10 is not required, and the elastic body 6 is more directly pressurized.

As described above, the present invention has an elastic body 6 in the part of the tightening screw 4.
By intervening, the pressing force on the object to be held can be adjusted to an appropriate value, and the object to be held will not be damaged or damaged, and concentrated stress will not act on areas with a small contact area and cause retrograde deformation. This has the effect of being able to adjust the pressurization appropriately to the extent that it does not occur.
