A kind of automatic assembly equipment of cylindrical helical spring resistance element

Abstract

The embodiment of the invention discloses automatic assembling equipment for a cylindrical helical spring-like resistor element. The automatic assembling equipment for the cylindrical helical spring-like resistor element is used for automatically assembling the cylindrical helical spring-like resistor element, which can improve the operating efficiency and the product quality. The automatic assembling equipment for the cylindrical helical spring-like resistor element comprises a driving mechanism, ceramic tube clamping mechanism and a resistor element clamping mechanism, wherein the driving mechanism comprises an input shaft, a gear shaft and an output shaft, and is used for driving a ceramic tube clamped on the ceramic tube clamping mechanism to rotate under the driving of a brake motor through the input shaft, the gear shaft and the output shaft which are connected with the brake motor; the ceramic tube clamping mechanism is connected with the output shaft; the ceramic tube clamping mechanism is used for clamping the ceramic tube; the resistor element clamping mechanism has a multi-connecting rod structure and is used for driving connecting rods to move under the pushing of an operating rod; and under the rotation of the ceramic tube clamping mechanism, the cylindrical helical spring-like resistor element is wound and pressed on the surface of the clamped ceramic tube.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an automatic assembly equipment for a cylindrical helical spring resistance element. Background technique [0002] In the power system, the neutral point grounding resistance with a small rated current usually uses a cylindrical helical spring resistance element. An important process in the production of the cylindrical helical spring resistance element is the installation of the cylindrical helix spring resistance element, that is, the cylindrical helical spring resistance element is installed. The spring-like resistance element is wound and fixed on the porcelain tube. At present, the existing installation method is to manually wind the cylindrical helical spring-shaped resistance element on the porcelain tube, that is, hold the porcelain tube with one hand and rotate the porcelain tube, and hold the cylindrical helical spring-shaped resistance element with the other hand. And th...

AI Technical Summary

Problems solved by technology

[0003] First: The tightness of the hand-assembled cylindrical helical spring-like resistance element and the porcelain tube cannot be guaranteed; different people or the same person assemble the cylindrical helical spring-like resistance element under different physical conditions, and the cylindrical helical spring-like resistance element and the porcelain tube There are differences in the tightness of the fit;

[0004] Second: The high intensity of manual assembly results in low assembly efficiency; manual assembly of cylindrical helical spring-shaped resistance elements and porcelain tubes can only assemble about 5 pieces per hour per person, and the efficiency is very low, which is far from meeting the needs of normal production;

[0005] Third: As the strength of manual assembly cannot be guaranteed to be consistent, the cylindrical helical spring-like resistance element may be too elongated or too short to be assembled on the porcelain tube, resulting in frequent rework and difficult to guarantee product quality
