Contact group assembling device

Abstract

The invention discloses a contact group assembling device which comprises a base, a guide rail assembly, an air cylinder assembly and a contact group fixing assembly. The guide rail assembly comprises a linear guide rail, a grating ruler and a sliding platform, the linear guide rail is fixed on the bearing surface of the base, and the sliding platform is slidably connected with the linear guide rail; a fixed ruler of the grating ruler is arranged on the side surface of the linear guide rail; the top surface of a movable ruler of the grating ruler is fixedly connected with the bottom surface of the sliding platform; the cylinder assembly comprises a fixing frame, a cylinder and a push block, the fixing frame is fixed on the bearing surface of the base, a main body part of the cylinder is clamped on the fixing frame, two end surfaces of the cylinder are respectively provided with a first piston rod and a second piston rod, the first piston rod is connected with the sliding platform, and the second piston rod is connected with the push block; the contact group fixing assembly is fixed on the bearing surface of the base, and the top of the contact group fixing assembly is provided with a limiting groove which is arranged corresponding to the push block. According to the invention, the measuring efficiency and the measuring precision of the contact group are improved, the manual operation is reduced, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of machining, in particular to a contact assembly device. Background technique [0002] The contact group is the core component of the fuse, which is mainly used to control the fuze circuit and the power supply of the timing lightning arrester, which directly affects whether the fuse operates reliably. The main index of the contact group is that the opening distance between each two contact pieces in the contact pieces is 0.3mm-0.5mm and the closing contact pressure is greater than 1.5N. [0003] The fuse contact group is fixed on the substrate by self-made screws. Before the assembly, the assembly of the contact sheet group is carried out first. The technical index requires the total assembly height of the contact group parts to be 24.5mm. The contact group components are mainly composed of screws, insulating sleeves, gaskets, insulating gaskets, contact sheet group I, contact sheet group II, contact sheet group I...

AI Technical Summary

Problems solved by technology

Sometimes it is necessary to fine-tune the copper adjusting shim (thickness 0.1mm), and use a vernier caliper to manually measure the assembly position of the contact piece, so as to determine the number and thickness of the adjusting shim, which is time-consuming and laborious, and the measurement is inaccurate

[0005] Aiming at the problems in the prior art that it is difficult to measure the relative position of each contact piece group during the assembly process of the fuser contact group components, it is difficult to determine the opening distance and closing contact pressure, and the operation is inconvenient, there is no effective solution at present.
