Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a tooling fixture for electric spark machining. Background Art

[0002] The fixtures for EDM are usually used to process metal workpieces with high hardness, high strength, high precision and complex shapes, such as molds, gears, turbine shafts, etc. It can use electric pulse discharge to perform cutting, drilling, engraving and other processing operations on the workpieces, and has the advantages of high processing accuracy and high processing efficiency;

[0003] Among them, the "A tooling fixture for machine tool bed processing" disclosed in the application number "CN219043765U" has solved the various drawbacks of the existing tooling fixtures that are prone to inaccurate positioning, resulting in unstable clamping of the tooling fixtures and affecting the bed processing. After further searching, it was found that the "A tooling fixture for electrospark machining" disclosed in the application number "CN204524472U" has effectively solved the problem that the existing fixtures cannot meet the requirements and are prone to large processing errors and precision errors by setting up 18 upper through holes on the rotary seat. The problem of low precision leads to defective or scrap finished parts, resulting in waste of resources and increasing processing costs. However, in actual use, there are still many defects in fixtures with similar structures. For example, the existing fixtures are usually processed by adjusting the position of the EDM device, which cannot meet most work requirements. At the same time, it is not convenient to fix the tooling according to different models and sizes. When other tooling needs to be processed, the fixture needs to be replaced frequently. The production flexibility and efficiency are not high. Therefore, it is necessary to design a tooling fixture for EDM. Utility Model Content

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Example:

[0027] Please combine Figure 1-5 A tooling fixture for electrospark machining in this embodiment includes a workbench 1, limit tables 101 are fixedly installed on both sides of the top of the workbench 1, a motor 2 and an auxiliary rod 3 are fixedly installed on the top of the workbench 1, a moving plate 203 is movably installed on one side of the motor 2 and the auxiliary rod 3, a bearing 401 is rotatably installed on the top of the moving plate 203, a limit plate 501 is movably installed on the top of the bearing 401, a liquid storage tank 6 is fixedly installed on the bottom of the workbench 1, and a water pump 603 is fixedly installed on one side of the liquid storage tank 6.

[0028] A water inlet hole 102 is formed on the inner wall of the workbench 1 , a liquid storage tank 6 is fixedly mounted at the bottom of the water inlet hole 102 , and a liquid inlet pipe 601 is fixedly mounted inside the liquid storage tank 6 .

[0034] The implementation principle of a tooling fixture for electrospark machining in the embodiment of the present application is as follows: the workbench 1 is placed in the area to be machined, and the movable seat 202 can be adjusted left and right along the slide bar 201 through the electric drive of the motor 2. When the movable seat 202 is adjusted left and right, the movable plate 203 can be driven to be adjusted, thereby driving the tooling clamped by the limit plate 501 to be adjusted left and right.

The movable seat 5 uses the adjustment of the limiting toothed disc 404 to allow the limiting plate 501 to adapt to tooling of different models and sizes, thereby reducing the number of fixtures that need to be designed and manufactured separately, avoiding the time waste of frequent fixture replacement, and improving production flexibility and efficiency.

[0036] By pouring spark oil into the interior of the workbench 1, when the tooling is being processed, the spark oil filled in the interior of the workbench 1 can be used to cool down the tooling being processed, the spark oil can be stored in the liquid storage tank 6 through the water inlet hole 102, and by inserting the liquid inlet pipe 601 into the liquid storage tank 6, it can be ensured that the water pump 603 controls the spark oil, and the waterproof pad 602 can be used to prevent the spark oil from flowing out of the gap between the liquid inlet pipe 601 and the liquid storage tank 6, and the spark oil can be recycled through the liquid outlet pipe 604. After being used to a certain extent, the spark oil can be discharged from the interior of the workbench 1 through the liquid outlet pipe 604.
