Description

Reformation vice

The present invention relates to an improved vise to which the technique of the present invention is applied. More specifically, the vise for fixing a workpiece for finishing and assembling work can be easily fixed regardless of the type, size and shape. It is about giving.

Vise is a tool that can fix the workpiece independently or fix it in a separate work object to facilitate finishing and finishing work using a line or hand grinder, or drilling and assembling work using a drill. Is one kind.

Such a vise is a situation in which various kinds of things such as box vise, leg vise and flat vise are conceived and used, and the double flat vise is configured as shown in FIG. 4.

Plain vice 1 is;

As a means for biting and fixing the workpiece on the front side of the base 2 provided in the form of a plate, a pair of jaws 5 composed of a fixed jaw 3 and a flow bath 4 is provided.

The fixing tank 3 of the tank 5 is bolted and fixed to the base 2 and the flow tank 4 is slidably coupled with the sliding rail 6 formed on the base 2 to allow movement freely.

The flow tank 4 is connected to the distal end of the screw 8 coupled with the handle 7 to the fixed block 6 fixed to the rear side of the base 2 to rotate by the operation of the handle (7) (8) is configured to slide forward and backward.

The conventional vise 1 as described above has a considerable problem in fixing the workpiece because the jaws for fixing the workpiece to be machined are simply composed of rectangular blocks.

That is, in the case of a general rectangular workpiece, it is possible to maintain the fixed state due to the increase of the friction surface while the surface of the jaw coincides with the surface of the jaw when the inserted workpiece is clamped by moving the flow tank after insertion between the ancestors.

However, there is considerable difficulty in fixing a round or elliptical workpiece or in the case of a square workpiece when the edge of the workpiece is to be connected to the jaw for the work.

In addition, even if the corners of the circular or rectangular workpiece is fixed to be in contact with the jaw, the fixing force is weak in the process of processing the workpiece, the workpiece is separated or moved.

As described above, when there is a flow or departure of the workpiece, there is a variety of problems such as processing of the workpiece cannot be made smoothly, especially in the process of using the power tool, physical damage of the worker due to the flow and departure of the workpiece.

In this invention, as designed to solve the problems as described above to improve the vice of the vise so that it can be easily fixed regardless of the type and shape of the workpiece;

It aims at contributing to the convenience of users and the improvement of the quality of the vise by making the work of the workpiece easier by excluding the flow and departure phenomenon when working in the fixed state.

Typical vise 30 is;

As a means for biting and fixing a workpiece on the front side of the base 31 provided in a plate shape, a pair of tanks 35 comprised of the fixing tank 32 and the flow tank 33 are provided.

The fixing tank 32 of the tank 35 is fixed to the base 31 and the bolt 36, the flow tank 33 is slidingly coupled with the sliding rail 37 formed on the base 31.

The flow tank 33 is connected to the front end of the screw 40 coupled with the handle 39 to the fixed block 38 fixed to the rear side of the base 31, the front end of the screw 40 is the flow tank It is coupled to the bearing 41 interposed in the interior of (33).

The flow tank 33 is slidably moved forward and backward by the base 31 to the screw 40 rotating by the operation of the handle 39 is inserted between the fixing tank 32 and the flow tank 33. Configure to hold the workpiece.

In the present invention, it is possible to easily fix the tank (35) consisting of the fixing tank (32) and the flow tank (33) regardless of the type and shape of the workpiece so that there is no flow and departure phenomenon.

Article 35 of the present invention for this purpose;

The upper jaw of the fixing tank 32 and the flow tank 33 to form a step (50) to prevent damage to the base 31 by the drill tip during the drilling operation.

An arc-shaped concave portion 51 is placed at the center of the step 50 to easily fix a circular or elliptical workpiece.

On the inner surface 52 of the fixing tank 32 and the flow tank 33 from the step 50 to the bottom surface to facilitate the corner fixation and the fixing of the unusual shape of the workpiece of a small circular workpiece or square The triangular fixing grooves 55 are further formed.

Vise 30 of the present invention as described above;

If you want to work by fixing the work, by using the handle (39) provided in the screw (40) to retract the flow tank 33 to the rear of the base 31, the workpiece to be worked with the flow of the fixed tank (32) After inserting between the tops of the tanks 33, the flow tank 33 is advanced by using the handle 39 again to fix the workpiece.

Since this series of operations is the same as the conventional vise, a detailed description thereof will be omitted, and a process of using the jaw 35 to which the technique of the present invention is applied will be described as follows.

In the case of fixing a rectangular workpiece, the fixing position varies depending on the type of machining operation.

That is, for example, finishing with a rope;

After inserting the workpiece into the fixing tank 32 and the inner surface 52 of the flow tank 33, the moving tank 33 may be moved and fixed. Particularly, a circular workpiece having a large diameter is formed in the tank 35. (50) It may be used after being inserted into the concave inlet portion 51 further formed in the center.

And for drilling operations;

By inserting and fixing the workpiece to the step 50, drilling is performed to prevent a phenomenon in which the drill tip penetrates the workpiece 31 and damages the base 31.

In addition, in order to fix an angled workpiece to the corner or to fix a difficult-to-fix workpiece, such as a circular circular workpiece;

By inserting and fixing between the triangular fixing grooves 55 formed from the center to the bottom of the step 50, the workpiece can be easily processed.

Vise 30 of the present invention as described above;

The jaw 35 can be improved to easily fix various kinds and shapes of workpieces, as well as to prevent the fixed workpiece from being easily detached, thereby facilitating machining and assembly of the workpieces, and This can prevent the risk of safety accidents such as physical damage.

The present invention as described above can be easily fixed regardless of the type and shape of the workpiece by improving the jaw of the vise, as well as to facilitate the processing work of the workpiece by excluding the flow and departure phenomenon when working in a fixed state By doing so, it can contribute to the improvement of user's convenience and the improvement of the quality of the vise.
