Description

Quick release fixtures for EDM

technical field

The utility model relates to a fast mounting fixture used in EDM.

Background technique

EDM (Electrical Discharge Machining , the abbreviation of Electrical Discharge Machining), uses the precision machining electrode to perform pulse spark discharge on the workpiece to remove metal and cut it into shape. It is mainly used to process various complex and precise workpieces. When performing EDM processing, it is often necessary to place the workpiece on the jig against the plate to match the processing angle for processing. However, the existing fixtures can only process a single workpiece correspondingly, resulting in waste of clamping and EDM discharge time, resulting in low processing efficiency.

Utility model content

The purpose of the utility model is to provide a fast-installation fixture used in EDM to solve the problem that the existing fixture can only process a single workpiece accordingly, and the processing efficiency is low.

In order to solve the above-mentioned technical problems, the utility model provides a quick-loading fixture applied to EDM, including a fixture main body and a positioning seat arranged at its bottom, the fixture main body is square, and it includes: several reference blocks arranged on its top, and The limit module arranged on its four side walls; the limit module includes a first limit block and a second limit block; the first limit block is fixed on two opposite side walls of the fixture main body; the second limit block The positioning blocks are fixed on the other two opposite side walls of the fixture main body; the second limiting block is provided with a longitudinally extending V-shaped groove on the side wall away from the connection with the clamp main body.

Further, several positioning holes are provided on the positioning seat.

Further, the first limit block is arranged on the edge of the corresponding side wall of the fixture main body.

Further, the second limit block is arranged in the middle of the corresponding side wall of the fixture main body.

Further, there are four reference blocks, which are respectively arranged on the four corners of the top of the fixture main body.

The beneficial effects of the utility model are: the utility model is provided with a first limit block and a second limit block, and in the working process, the workpiece facing directly can be pressed against the side wall of the fixture main body to facilitate processing; When processing non-straight-facing workpieces such as circular workpieces, the non-straight-facing workpiece can be clamped in the V-shaped groove on the second limit block. Adopting the utility model for EDM processing can not only process a plurality of workpieces at the same time to improve work efficiency, but also be applicable to workpieces of different shapes.

Detailed ways

The specific embodiment of the present utility model is described below, so that those skilled in the art understand the utility model, but should be clear, the utility model is not limited to the scope of specific embodiment, for those of ordinary skill in the art, as long as Various changes are within the spirit and scope of the utility model defined and determined by the appended claims, and these changes are obvious, and all inventions and creations utilizing the concept of the utility model are all included in the protection list.

As shown in Figures 1 to 3, the quick-release fixture used in EDM includes a fixture body 1 and a positioning seat 2 arranged at the bottom thereof, and is characterized in that the fixture body 1 is square, and it includes several benchmarks arranged on its top Block 11, and the limit modules arranged on its four side walls. In this embodiment, there are four reference blocks 11 , which are respectively arranged on four corners of the top of the fixture main body 1 .

The limit module includes a first limit block 12 and a second limit block 13; the first limit block 12 is fixed on two opposite side walls of the clamp body 1; the second limit block 13 is fixed on the side wall of the clamp body 1 On the other two opposite side walls; the side wall of the second limiting block 13 away from the connection with the clamp body 1 is provided with a vertically extending V-shaped groove 131 . Wherein, the first limiting block 12 is arranged on the edge of the corresponding side wall of the fixture main body 1 . The second limiting block 13 is arranged in the middle of the corresponding side wall of the clamp body 1 .

As shown in Figure 2 and Figure 3, the bottom of the positioning seat 2 is provided with several positioning holes 21, 22, 23; wherein the positioning seat 2 is fixed on the EDM machine head through the positioning holes 21, 22, 23.

When the fixture is in use, its positioning seat 2 is fixed on the head of the EDM machine tool, and the reference block 11 on its top is fixed on the EDM workbench. The fixture is provided with a first limit block 12 and a second limit block 13. During the working process, multiple straight workpieces can be placed against the side wall of the fixture main body 1 to facilitate processing; When the non-straight-facing workpiece is processed, the non-straight-facing workpiece can be clamped in the V-shaped groove 131 on the second limit block 13 . Adopting the utility model for EDM processing can not only process a plurality of workpieces at the same time to improve work efficiency, but also be applicable to workpieces of different shapes.
