Electric spark deposition contact force controlling device with damping function

Abstract

The invention relates to an electric spark deposition contact force controlling device with a damping function. The electric spark deposition contact force controlling device with the damping functionmainly comprises an air cylinder, a sliding table, a base, a weight, a clamping mechanism, an angle adjusting device, a throttle valve, a pressure gauge, an inflating valve and the like, wherein themoving direction of a piston of the air cylinder is consistent with the moving direction of the sliding table, and the sliding table moves when the piston moves, so that an electrode is driven to moveup and down, and when the electrode moves downwards, the electrode makes contact with a workpiece. The gravity of a sliding part is counteracted by using thrust generated by the air cylinder in an airtight pneumatic system, the sliding part is pushed by the gravity of the weight to move downwards to form contact force between the electrode and the workpiece, the throttle valve in the airtight pneumatic system generates damping on movement of the piston, electrode vibration caused by recoil force generated in a moving process of the electrode and the workpiece is restrained, in an electric spark deposition surfacing process, stable contact between the electrode and the workpiece and constant contact force can be ensured along with electrode loss and movement of the sliding table, work is reliable, and adjustment is convenient.

Description

technical field [0001] The invention relates to the technical field of electric spark deposition, in particular to an electric spark deposition contact force control device with a damping function. Background technique [0002] EDM surfacing technology is a surface treatment technology that utilizes tool electrode material migration to the workpiece surface during EDM to form a dense strengthening layer to form a dense strengthening layer, thereby improving the surface properties of the workpiece. [0003] In the process of EDM deposition welding, the electrode and the workpiece need to be in constant contact to generate electric sparks for deposition and surfacing. The contact force between the electrode and the workpiece is a key factor controlling the efficiency of deposition surfacing and the quality of the deposited layer. However, at present, EDM surfacing is mostly completed by manual operation. The staff usually rely on experience to maintain a certain contact force ...

AI Technical Summary

Problems solved by technology

[0006] At present, some contact force automatic control devices for EDM surfacing have been designed, but most of them are relatively complicated, and lack damping function in the case of small contact force, resulting in serious vibration and affecting the stability and quality of operation.
