Rotary shaft compressive strength testing device

Abstract

The invention provides a testing device for the compressive strength of a rotating shaft, which includes an operating table, a first testing component and a second testing component, the first testing component includes two testing blocks, and the two testing The blocks can move toward / backwards along the same straight line path, the detection block is provided with a joint that can be elastically pressed on the rotating shaft to be tested, and the two joints can position the rotating shaft to be tested, the first The second detection component includes a driving part and a detection final shaft. The driving part is used to drive the rotating shaft to be tested to rotate, and the driving part can move toward / away from the detection final shaft. Aiming at the deficiencies of the prior art, the present invention provides a testing device for the compressive strength of a rotating shaft, which can effectively reduce labor costs and time costs.

Description

technical field [0001] The invention relates to a detection device for the compressive strength of a rotating shaft. Background technique [0002] The rotating shaft is a mechanical part that supports the rotating parts and rotates with them to transmit motion, torque or bending moment. It is generally in the shape of a metal round rod, and each section can have different diameters. The parts that rotate in the machine are installed on the shaft. Depending on the production process, its own specifications, etc., and the influence of environmental factors in the processing process, the shaft will have various situations, resulting in differences in the quality of different shafts produced. Therefore, the shaft needs to be tested for different batches when it leaves the factory. For sampling testing, the pressure test of the rotating shaft often requires the operator to operate the pressure detector to perform axial pressure testing and radial pressure testing during rotation....

[0002] The rotating shaft is a mechanical part that supports the rotating parts and rotates with them to transmit motion, torque or bending moment. It is generally in the shape of a metal round rod, and each section can have different diameters. The parts that rotate in the machine are installed on the shaft. Depending on the production process, its own specifications, etc., and the influence of environmental factors in the processing process, the shaft will have various situations, resulting in differences in the quality of different shafts produced. Therefore, the shaft needs to be tested for different batches when it leaves the factory. Sampling testing, among which the pressure test of the rotating shaft often requires the operator to operate the pressure detector to perform axial pressure testing and radial pressure testing during rotation. The process is cumbersome and requires a large labor cost and time cost.
