[0003] However, in the prior art, the concentricity of the joint pin is tested after production, and the test requires the use of a concentricity detection device, which is used to measure and evaluate the concentricity of the joint pin, that is, the degree of axial alignment between the joint pin and the bearing hole or the connecting component. It can help determine the accuracy and quality of the joint pin and ensure its normal operation during assembly and use. However, there are multiple concentricity detection devices, one of which mainly relies on a detection mechanism and a positioning mechanism to position the joint pin when testing the joint pin, and the joint pin will be in a suspended state during the test, and the suspended state will cause the joint pin to rely on two ends for positioning support, and the positioning support at both ends may cause unstable positioning, and the joint pin may have a certain offset, resulting in inaccurate test data. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. During detection, the joint pin will be in a suspended state, and the suspended state will cause the joint pin to rely on two ends for positioning support. The positioning support at both ends may cause unstable positioning, and the joint pin may have a certain deviation, which will lead to inaccurate detection data. A mechanical joint pin concentricity detection device is provided.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mechanical joint pin concentricity detection device, comprising: a concentricity detection device body, a receiving structure is arranged on the top of the concentricity detection device body, a clamping structure is arranged on the top of the concentricity detection device body through the receiving structure, the clamping structure comprises an extension block connected to the receiving structure, a threaded through hole is provided on the outer surface of the extension block, a threaded rod is connected to the inside of the threaded through hole through a thread, the front end of the threaded rod is connected to the clamping block through a bearing, and a rubber clamping pad is fixed to one side of the outer surface of the clamping block.

[0006] As a preferred implementation manner, a positioning mechanism is provided on the top of the body of the concentricity detection device, and a detection mechanism is provided on the top of the body of the concentricity detection device.

[0007] As a preferred implementation, the receiving structure includes a fixing plate, a fixing block is fixed on the top of the fixing plate, and a receiving block is fixed on one side of the outer surface of the fixing block.

[0008] As a preferred implementation manner, a receiving groove is provided on the top of the receiving block, and a bearing groove is provided on the bottom surface of the receiving groove.

[0009] As a preferred embodiment, two fixing plates are provided, and are respectively arranged on the top of the concentricity detection device body.

[0010] As a preferred embodiment, there are two extension blocks in total, which are respectively arranged on one side of the outer surface of the fixed block and arranged in opposite surfaces.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] In order to solve the above-mentioned problems, the utility model plays a supporting and clamping role for the joint pin shaft through the linkage action of the supporting structure and the clamping structure, wherein the supporting structure plays a supporting role for the joint pin shaft, and the clamping structure plays a clamping role for the joint pin shaft. Through the linkage action of the two, the deviation caused by the outer surface of the joint pin shaft being unloaded and relying on the positioning mechanism and the detection mechanism to position the two ends of the joint pin shaft can be avoided.
