Problems solved by technology

[0002] A large number of burrs are produced on high-voltage copper contacts after machining, which seriously affects their functions. The main manifestations are: the high-voltage power environment is very sensitive to burrs. The service life of copper contacts is shortened, and the metal vapor and powder generated in this process are filled in the arc extinguishing chamber or the air, which greatly reduces the dielectric strength of the medium, affects the breaking ability of the circuit breaker, and causes immeasurable safety hazards, so it must be taken Effective way to remove burrs as clean as possible
[0003] Due to various reasons, the enterprise currently adopts the method of manual removal to manually remove the burrs of the high-voltage copper contacts. Finger clamping, resulting in low removal efficiency of finger burrs, poor removal consistency, and high production costs

Abstract

The invention discloses a high-pressure copper finger touch fixture. The high-pressure copper finger touch fixture comprises a base; the base is connected with a detecting mechanism and an indexing mechanism; and the indexing mechanism is connected with a finger touch clamping mechanism. The high-pressure copper finger touch fixture can realize three functions: (1) the finger touch clamping is realized by dint of the finger touch clamping mechanism; (2) the indexing function is realized by dint of the indexing mechanism; and (3) the detecting function is finished by dint of the detecting mechanism. The invention further discloses a finger touch clamping method; the finger touch clamping adopts forward and reverse clamping; the finger touch clamping method conveniently and quickly performs the finger touch clamping; and the method is high in finger touch burr removing efficiency and excellent in removing quality.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing fixtures, and relates to a fixture for high-voltage copper contact fingers, and also relates to a method for clamping contacts by using the above-mentioned fixture for high-voltage copper contact fingers. Background technique [0002] A large number of burrs are produced on high-voltage copper contacts after machining, which seriously affects their functions. The main manifestations are: the high-voltage power environment is very sensitive to burrs. The service life of copper contacts is shortened, and the metal vapor and powder generated in this process are filled in the arc extinguishing chamber or the air, which greatly reduces the dielectric strength of the medium, affects the breaking ability of the circuit breaker, and causes immeasurable safety hazards, so it must be taken An effective way to remove the burrs as cleanly as possible. [0003] Due to various reasons, the enterp...
