Bearing capacity detection equipment adaptive to heavy truck transmission shafts with different diameter specifications

Abstract

The invention relates to the technical field of heavy truck part detection, particularly to bearing capacity detection equipment adaptive to heavy truck transmission shafts with different diameter specifications. The bearing capacity detection equipment is characterized in that centering adjustment and fixation of the positions of a transmission shaft in upper, lower, left and right directions through a second centering and positioning device and a third centering and positioning device in a gear and rack form; one end of the transmission shaft is clamped and fixed through cooperation of the first flexible arc-shaped pad and the pressing plate of a first centering and positioning device; and in a pressure applying device structure, by designing the structures of a second adjusting air cylinder and a second flexible arc-shaped pad, after a second sliding base moves downwards, the second flexible arc-shaped pad can be attached to the surface of the transmission shaft in a large area, so that by increasing the contact area, the pressure applying device can apply downward pressure to the transmission shaft more stably, and the accuracy of the bearing capacity detection result of the transmission shaft is ensured. According to the invention, the structure can be used for centering and fixing transmission shafts with different diameter 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 bearing capacity detection device adapted to transmission shafts of heavy trucks with different diameters and specifications. 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...

[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 Rich, resulting in the demand for testing the bearing capacity of transmission shafts with different diameters, how to efficiently and stably carry out accurate testing of the bearing capacity for transmission shafts with different diameters is a technical problem that needs to be solved urgently
