Description

Technical Field

[0001] The invention relates to the field of clamping mechanism equipment, and in particular to a connecting rod detection device. Background Art

[0002] The engine connecting rod is an important part of the engine. Its main function is to connect the piston and the crankshaft, transfer the power generated by the piston movement to the crankshaft, and drive the engine to operate. If the connecting rod is bent and deformed, it may cause imbalance during engine operation, resulting in increased vibration and noise. This not only affects driving comfort, but may also accelerate the wear and damage of surrounding parts.

[0003] However, the existing manual detection methods of engine connecting rod bending deformation rely on the operator's experience and skill level and cannot achieve real-time monitoring. In addition, some methods require a lot of time and resources to use corresponding connecting rod testers for detection. The design structure of the connecting rod tester is relatively complex, and the detection process is also relatively cumbersome, resulting in low detection efficiency.

[0004] Therefore, a new connecting rod detection device is needed, which can detect whether the engine connecting rod is bent or deformed in real time. Summary of the invention

[0008] Furthermore, the elastic member 1 includes a spring.

[0009] Furthermore, the two clamping parts are arranged to be inclined relative to each other at a predetermined angle.

[0010] Furthermore, the driving device 1 includes an elastic member 2.

[0011] Furthermore, the elastic member 2 includes a torsion spring 1, which is arranged on the supporting portion and is used to drive the shell 1 to rotate.

[0019] In the above technical scheme, a limit assembly is provided to fix one end of the large ring of the connecting rod, and a pin is provided on the small ring of the connecting rod. A driving device is used to drive a shell, so that the shell drives the slider, and the slider drives the clamping part 1 and the clamping part 2 to contact the pin. The slide column is used to be rotated so that the protrusion is away from the limit groove, so that the elastic part drives the supporting part to contact the clamping part 1, drives the slider to move along the slide groove, and causes the clamping part 2 to contact the base. The rotation angle of the slider is determined by judging whether the contact part 1 and the contact part 2 contact the base at the same time, thereby judging whether the small ring of the engine connecting rod as a workpiece is bent relative to the large ring, thereby achieving the effect of real-time detection of whether the engine connecting rod is bent and deformed.
