Automatic spotting device for torque converter pump wheel

Abstract

The invention provides an automatic copper paste dispensing device for torque converter pump pulleys. The automatic copper paste dispensing device comprises a pump pulley rotating assembly, a dispensing assembly and one or more ascending-and-descending assemblies. The pump pulley rotating assembly comprises a deceleration stepping motor and a rotating disc at a minimum, and the bottom of the rotating disc is mounted on an output shaft of the deceleration stepping motor. The dispensing assembly comprises a supporting bracket and multiple paste dispensing barrels; the multiple paste dispensing barrels are fixed to the supporting bracket; a paste dispensing head of each paste dispensing barrel extends out of the lower side of the supporting bracket; and the paste dispensing heads are aligned with the position of the rotating disc. Each ascending-and-descending assembly comprises an ascending-and-descending air cylinder, ascending-and-descending sliding rails and an ascending-and-descending sliding block; the extending direction of each ascending-and-descending sliding rail is the same as the movement direction of a piston rod of the corresponding ascending-and-descending air cylinder; each ascending-and-descending sliding block is fixedly connected with the piston rod of the corresponding ascending-and-descending air cylinder; and the ascending-and-descending assemblies control the supporting bracket of the dispensing assembly to perform vertical ascending and descending motion. The automatic copper paste dispensing device has the beneficial effects that labor intensity of brazing of the pump pulleys is lowered; production efficiency of brazing of the pump pulleys is improved; and brazing quality and controllability of copper material consumption are improved.

Description

technical field [0001] The invention relates to a device for automatically dispensing copper paste on a pump wheel of a torque converter. Background technique [0002] The pump wheel of the stamping and welding type hydraulic torque converter needs to be brazed. The brazing base material is copper wire. There are the following defects in brazing the pump wheel by the above method: 1. The shearing and bending of copper wire takes up a 22Kw punch press and a pair of molds, which has high energy consumption and labor intensity, and low production efficiency; Storage and production cycle is long. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic copper paste spotting device for the pump wheel of the torque converter with simple operation and high degree of automation. [0004] In order to solve the above technical problems, the present invention provides a torque converter pump wheel automatic point copp...
