[0002] After the workpiece is machined, it is usually necessary to inspect it to ensure that the workpiece accuracy meets the design requirements, usually including length inspection, external cylindrical runout inspection and straightness inspection.

[0003] In existing equipment, different equipment is usually used to test each parameter of the workpiece, which increases the investment cost of the testing equipment. It is not possible to complete multiple tests on the same device, which makes the operation inconvenient and reduces the testing efficiency. Secondly, the contact detection adopted in the existing technology will cause the workpiece to be subjected to force, and the detection accuracy cannot be well guaranteed, resulting in the detection being inaccurate and unreliable.

[0004] Therefore, how to design a workpiece comprehensive detection equipment with a simpler and more reasonable structural design, which can improve detection efficiency, more conveniently complete detection operations, and improve detection accuracy and reliability has become a technical problem to be solved by technical personnel in this field.

[0112] In this way, the structural design of the fixed support is simpler, and the position of the servo drive motor can be adjusted more conveniently, thereby adjusting the transmission efficiency.

[0113] Specifically, two triangular-shaped stabilizing support blocks 89 are provided in pairs between the fixed support plate and the fixed bottom plate.

[0114] In this way, by providing a stabilizing support block, the stability of the structure can be improved.

[0115] In summary, the above equipment is used to complete the length detection, outer circle runout detection and straightness detection of the workpiece, and non-contact detection is adopted. The non-contact detection method can better avoid the damage to the workpiece caused by the detection contact and better protect the integrity of the workpiece. Secondly, during the detection process, the workpiece is not subjected to external forces, which can better avoid the deformation of the workpiece, thereby better improving the accuracy and reliability of the detection.

[0116] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
