Description

Adjustable electrode verticality fixture

technical field

The utility model belongs to auxiliary tooling for electric discharge machining, in particular to a clamp that can adjust the perpendicularity of electrodes.

Background technique

For a long time, the electrode fixtures on the market are expensive, and pneumatic clamping is required to ensure that the electrodes are vertical, which limits EDM to a certain extent. However, it is difficult to ensure the verticality of the electrode by using a general three-jaw chuck to fix the electrode, causing the machining to be inclined and the workpiece to be scrapped.

technical problem to be solved

In order to solve the above problems, the utility model provides a clamp for fixing the three-jaw chuck with adjustable electrode verticality.

Technical solutions

The technical scheme adopted by the utility model is: the clamp that can adjust the verticality of the electrode is mainly composed of an upper clamping block, a lower clamping block, a ball, a screw and a set screw. The upper clamping block is fixedly connected to the fixed seat of the machine tool. There is a concave spherical surface in the center of the opposite surface of the upper clamping block and the lower clamping block. The ball is located in the middle of the spherical surface of the upper and lower clamping blocks. A certain distance is left between the upper and lower clamping blocks interval, the upper and lower clamping blocks are fixedly connected together with several screws, and a hole for fixing electrodes is provided under the lower clamping block.

The utility model is characterized in that: the concave spherical surface at the center of the opposite surface of the upper clamping block and the lower clamping block has a diameter S of φ10-30 mm, and the depth from the center of the concave surface to the surface of the clamping block is between 5-10 mm.

Another feature of the utility model is that: the distance between the upper and lower clamping blocks is between 5mm and 10mm.

When processing, install the fixture described in the utility model on the machine tool, insert the electrode into the hole below the lower clamping block, and fix it with a set screw, then adjust the tightness of the screw between the upper and lower clamping blocks, After aligning the electrodes so that they are in a vertical position, tighten the screws.
