Description

A Simple Electric Discharge Machine Fixture

technical field

The utility model relates to a simple electric discharge machine tool fixture.

Background technique

In the mold processing industry, EDM machine tools are widely used and can solve the processing of complex cavities and play an important role in the manufacturing industry. However, when the EDM machine tool is used, it is necessary to process screw holes on the electrode, connect the connecting rod and the electrode together and install it on the EDM machine tool. It is troublesome to align the electrode installation, low efficiency and waste of time. Fixtures are relatively expensive, and ordinary mold companies cannot afford them.

In view of this, the inventor has invented a kind of simple and easy electrical discharge machine clamp, and this case arises thus.

Utility model content

The purpose of this utility model is to provide a simple electric spark machine tool fixture. Aiming at the disadvantages of troublesome installation and alignment of electrodes, low efficiency and time-wasting, by designing a simple electric spark machine tool fixture, the clamping efficiency of electrodes is greatly improved .

In order to achieve the above object, the utility model is achieved through the following technical solutions:

A simple electric discharge machine tool fixture, including a fixture body, the fixture body includes an upper part and a lower part, the upper part is triangular, the lower part is a hollow quadrilateral, and two adjacent sides of the lower part are provided with threaded holes , the screw is installed in the threaded hole, and the end of the screw is installed with a quadrilateral clamping block, and the clamping block is located on the inner side of the lower part.

Arc-shaped grooves are provided on the four corners inside the lower part.

The beneficial effects of the utility model are as follows:

The simple EDM fixture of the utility model has a simple structure and is convenient to process. It is mainly suitable for clamping square electrodes. The clamping range is adjustable. It can be processed and used in general factories, which greatly improves the clamping efficiency of the electrodes. There is no need to process threads on the electrodes. hole, can be directly clamped to the fixture, and can also save electrode material.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the structural representation of the bottom in the utility model;

Wherein, 1 is an upper part, 2 is a lower part, 3 is a screw, 4 is a clamping block, and 5 is a groove.

Detailed ways

The utility model will be further described below in conjunction with specific embodiments, but the protection scope of the utility model is not limited thereto.

As shown in Figures 1 and 2, the simple EDM clamp of the utility model includes a clamp body, the clamp body includes an upper part 1 and a lower part 2, and the upper part 1 is a triangle, which coincides with the triangular inner hole of the chuck of the EDM machine tool. The initial positioning of the electrode can be realized, thereby improving the clamping efficiency and greatly saving time.

The lower part 2 in the utility model is a hollow quadrilateral, and two adjacent side surfaces of the lower part 2 are provided with screw holes (not marked in the accompanying drawings of the utility model), and screws 3 are installed in the screw holes, and the screws 3 A quadrilateral clamping block 4 is installed at the end for clamping the electrodes.

The clamping block 4 in the utility model is located in the inner side of the lower part 2, and the screw 3 drives the clamping block 4 to be able to expand and contract freely, thereby realizing the clamping of electrodes of different sizes and improving the use range of the clamp.

The plane of the clamping block 4 in the utility model can protect the electrodes, avoiding the damage to the electrodes caused by the direct electrodes of the screws 3 .

Arc-shaped grooves 5 are all provided on the four corners inside the lower part 2 in the utility model.

When in use, first place the electrode in the groove 5 of the clamp body, adjust the screws 3 installed on the two sides of the clamp body respectively, thereby driving the clamping block 4 to move, and clamp the electrode, and then place the simple clamp for clamping the electrode It is installed on the electric discharge forming machine as a whole, so as to realize the purpose of fast clamping.

The simple EDM fixture of the utility model has a simple structure and is convenient to process. It is mainly suitable for clamping square electrodes. The clamping range is adjustable. It can be processed and used in general factories, which greatly improves the clamping efficiency of the electrodes. There is no need to process threads on the electrodes. hole, can be directly clamped to the fixture, and can also save electrode material.

The above-mentioned embodiments and drawings are only used to explain the inventive concept of the present utility model, and do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those skilled in the art should be regarded as For not departing from the patent category of the present utility model.
