Quick static twisting detection device of constant speed universal joint driving shaft friction welding piece

Abstract

The invention provides a quick static twisting detection device of a constant speed universal joint driving shaft friction welding piece. The quick static twisting detection device comprises a transmission system arranged on a machine body and used for locating and twisting a work piece to be detected and a power supply driving the transmission system to rotate. A rocker arm is arranged on the transmission system, and the power system is connected with the rocker arm and and drives the rocker arm to rotate to achieve connection with the transmission system and drive the transmission system to rotate to twist the work piece to be detected. The power supply system comprises a hydraulic oil cylinder 1a connecting the machine body and one end of the rocker arm and a hydraulic oil cylinder 1b connecting the machine body and the other end of the rocker arm, and the hydraulic oil cylinder 1a and the hydraulic oi cylinder 1b work through the hydraulic control system. The quick static twisting detection device is simple in structure, simple to operate, low in electric cost, convenient to maintain, accurate and reliable in data detection, high in detection efficiency, short in detection period, low in detection cost and high in traceability of product experiment data.

Description

technical field [0001] The invention relates to a detection device for a drive shaft of a universal joint, in particular to a fast static torsion detection device for a friction welded part of a drive shaft of a constant velocity universal joint. Background technique [0002] The drive shaft of the car is responsible for the power torque transmission function from the differential or the final reduction gear to the driving wheel. It has high requirements for torsion resistance and bending resistance. It is one of the key components in the car transmission system and has a great impact on the performance of the vehicle. , and the static torsional strength of the drive shaft friction weldment of the constant velocity universal joint—that is, the static torsional strength is an important technical index for evaluating the processing quality of the drive shaft friction weldment. The existing constant velocity universal joint drive shaft friction weldment static torsion detection...

AI Technical Summary

Problems solved by technology

The above-mentioned existing constant-velocity drive shaft friction weldment static torsion detection device can meet the general detection requirements of the drive shaft, but there are high motor power requirements, large self-damage power, data acquisition points of the data acquisition system and torque output points of the loading system. Prone to a series of problems such as time deviation, cumbersome data collection and storage, long detection cycle, and low single-piece detection efficiency, which not only increase the energy consumption of the experiment, reduce the detection efficiency, increase the cost of the experiment, but also seriously affect the accuracy of the detection data , reliability, resulting in misjudgment of product processing quality
