Automatic assembling machine for carbon brush frame torsional spring

Abstract

The invention relates to an automatic assembling machine for a carbon brush frame torsional spring. The automatic assembling machine is characterized by comprising a substrate, a bracket and a control system, wherein the bracket is fixedly arranged on the substrate; the bracket is provided with a pressure air cylinder; a pressure plate is fixedly connected with a piston rod of the pressure air cylinder; and a torsional spring expanding mechanism is arranged on the substrate below the pressure plate. The automatic assembling machine has the advantages of simple and compact structure and convenience in operating; and the requirements of physical strength and operation technique of operation workers are lowered, rapid and efficient auxiliary equipment is provided for the assembling of the carbon brush frame torsional spring, the labor intensity of the operation workers is relieved, the yield of a product is increased, the working efficiency is increased, and the production cost is reduced.

Description

technical field [0001] The invention relates to torsion spring assembly equipment, in particular to an automatic torsion spring assembly machine for carbon brush holders. Background technique [0002] The size of the torsion spring of the carbon brush of the car starter is small (the outer diameter generally does not exceed 14mm), and the industry usually uses simple tools such as needle-nose pliers and screwdrivers to install it manually. The elastic force is rotated at a certain angle and then installed on the spring column of the carbon brush holder. The installation process of the torsion spring requires high physical strength and operational skills of the operator, the operation is difficult, and the labor intensity of the worker is high. The spring will be damaged to varying degrees, reducing the qualified rate of the product. At the same time, the efficiency of manual installation is low, and with the continuous increase of labor costs, the manufacturing cost of the p...
