Lifting and swinging mechanism of automobile transmission shaft and dust cover testing machine

Abstract

The invention discloses a lifting and swing mechanism of a vehicle transmission shaft and dust cover tester. The lifting and swing mechanism comprises a swing arm, an upper connecting plate, a lower connecting plate, a swing shaft connecting device and a swing arm lifting device, wherein the upper connecting plate is fixedly connected with the upper end of the swing arm, the lower connecting plate is fixedly connected with the lower end of the swing arm, the swing shaft connecting device is arranged on the upper connecting plate to drive the swing arm to swing, and the swing arm lifting device is arranged on the lower connecting plate to drive the swing arm to vertically move. The swing shaft connecting device is composed of an idler wheel set device and a swing shaft, wherein the idler wheel set device and the swing shaft are arranged in one connecting plate, the swing shaft is inserted into the idler set device to be in transmission connection with the upper connecting plate, and the swing arm vertically moves along the swing shaft under the drive of the swing arm lifting device. By the adoption of the lifting and swing mechanism, abrasion of the swing shaft can be greatly reduced, swing of a lead screw can be avoided, the service life of the swing shaft and the lead screw is effectively prolonged, and maintenance cost is low.

Description

technical field [0001] The present invention relates to a test device, more specifically, relates to an automobile drive shaft and dustproof cover which can be used for anti-torsion, tension, swing, high, low temperature, anti-aging and other tests on the drive shaft and dust cover of the automobile. The lifting and swinging mechanism of the cover testing machine. Background technique [0002] The traditional lift and swing mechanism of the car drive shaft and dust cover testing machine used for torsion and tensile tests on the car drive shaft and dust cover, the swing shaft is directly connected to the upper connecting plate, and the swing shaft is easy to wear , short service life. In addition, the lower connecting plate and the support are fixedly connected together, and the screw will swing with the swing arm, which will affect the stability of the equipment operation, and the screw cannot be effectively lubricated, and it is easy to wear, thereby reducing the dust resi...
