Stretch-compress integrated automobile transmission shaft detection apparatus

Abstract

The invention discloses a stretch-compress integrated automobile transmission shaft detection apparatus comprising a base, a slide rail, a fixed plate, a movable plate, two stopper baffle, cylinder clamping device, a motor driving device, a pulling force measuring device, and a support device. The slide rail is fixed to the base and is equipped with the fixed plate and the movable plate. A side, far from the movable plate, of the fixed plate is connected with the pulling force measuring device. The motor driving device is connected with the movable plate and drives the movable plate to freely slide on the slide rail. The fixed plate and the movable plate are both equipped with the cylinder clamping devices. The two stopper baffles are fixed to the outer sides of the two cylinder clamping devices respectively. The base under the slide rail is also provided with a magnetic railing ruler for measuring the length of an automobile transmission shaft. The stretch-compress integrated automobile transmission shaft detection apparatus may compress a tested workpiece with set force and detect the length of the workpiece so as to determine whether the workpiece is qualified according to a set qualified workpiece length range, and may stretch the automobile transmission shaft with set pulling force in order to inspect whether an elastic closing ring is assembled in place.

Description

technical field [0001] The invention relates to the field of auto parts testing equipment, and more specifically relates to a tension-compression integrated vehicle transmission shaft testing device. Background technique [0002] The automobile transmission shaft is the shaft that can transmit power in the transmission shaft of the universal transmission device. It is a rotating body with high speed and less support. The automobile transmission shaft is the most important component for transmitting power in the automobile transmission system. Together with the drive axle, the power of the engine is transmitted to the wheels, so that the car generates driving force. [0003] The automobile drive shaft is usually composed of a shaft tube, a telescopic sleeve and a universal joint. There are two telescopic sleeves which are respectively arranged at both ends of the shaft tube. The two telescopic sleeves are respectively connected to the two ends of the shaft tube through two un...

AI Technical Summary

Problems solved by technology

In the process of measuring the length of the automobile transmission shaft, it is usually necessary to measure the automobile transmission shaft under the action of constant pressure, and when the force is applied, too much force will directly cause the deformation of the automobile transmission shaft and affect the measurement results. Therefore how to ensure that the force value during measurement will not exceed the preset value is also a difficulty of the present invention
