Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp used for an electric spark machine. Background Art

[0002] The electric spark machine is a special processing method that uses the electro-erosion effect generated by pulse discharge between two electrodes immersed in a working fluid to remove conductive materials. During the use of the electric spark machine, a fixture is required to clamp and fix the workpiece.

[0003] In the prior art, a clamp for an electric spark machine with a publication number of CN210451277U adopts a scheme of "including a base plate, a fixing plate fixedly installed on the top of the base plate, a fastening screw fixedly installed on the surface of the fixing plate, a fixing device fixedly installed on the left side of the fixing plate, a sliding groove opened on the top of the fixing device, a clamping block frictionally connected to the top of the sliding groove, and a buffer device movably installed on the left side of the clamping block". This scheme provides a buffer device, so that when the clamp is clamping parts for processing, the telescopic spring in the buffer device and the rubber pad on the surface of the buffer device protect the surface of the parts. During processing, when the clamp is clamping parts, and because the force of the clamp cannot be adjusted, the clamp will suddenly clamp the parts, and the spring inside the buffer device will absorb the clamping force of the clamp suddenly clamping the parts, thereby increasing the safety of the device.

[0004] However, the above solution still has some shortcomings. For example, during the actual use of the fixture, the debris generated by the electric spark machine processing is very easy to be retained on the inner wall of the sliding groove, which makes the subsequent cleaning very inconvenient. That is, the technical solution proposed by the above patent technology has the defect that the debris generated by the processing cannot be quickly cleaned.

[0005] In view of this, the utility model provides a clamp for an electric spark machine. Utility Model Content
