Bearing capacity detection device of heavy truck transmission shaft

Abstract

The invention relates to the technical field of heavy truck part detection, in particular to a hoisting fixture for a heavy truck plate-shaped part, which comprises a rack, a first centering and positioning device, a second centering and positioning device, a third centering and positioning device and a pressure applying device. One end of a transmission shaft is fixed through a three-jaw chuck, preliminary centering fixing is achieved, centering adjustment and fixing of the transmission shaft in the upper direction, the lower direction, the left direction and the right direction are achieved through the second centering and positioning device and the third centering and positioning device which are in a gear and rack form, and in the pressure applying device structure, the structure of an adjusting air cylinder and a flexible arc-shaped pad is designed, after the sliding seat moves downwards, the flexible arc-shaped pad can be attached to the surface of the transmission shaft in a large area, the pressure applying device can apply downward pressure to the transmission shaft more stably by increasing the contact area, and the accuracy of the bearing capacity detection result of the transmission shaft is guaranteed. The structure can be used for centering and fixing transmission shafts with different diameters and models and accurately detecting the bearing capacity.

Description

technical field [0001] The invention relates to the technical field of detection of heavy truck parts, in particular to a lifting fixture for heavy truck plate parts. Background technique [0002] Heavy trucks usually need to carry heavy goods, and their transmission shafts need a strong bearing capacity to avoid bending and fracture of the transmission shaft under heavy loads. Therefore, it is necessary to test the bearing capacity of the transmission shaft. The device is composed of a fixing device and a pressure detection device; however, the original fixing device can only be fixed for a single specification of the transmission shaft, and it is mainly fixed by bolts. The fixing of the transmission shaft requires a lot of man-hours, and with the increase of The richness has created the demand for bearing capacity testing of drive shafts with different diameters. How to efficiently, stably and accurately test the bearing capacity of drive shafts with different diameters is...
