Description

Technical Field

[0001] This utility model relates to the field of crankshaft testing technology, and more specifically to a rapid crankshaft testing device. Background Technology

[0002] The crankshaft is the most important component in an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other accessories on the engine. The rotation of the crankshaft is the power source of the engine and the source of power for the entire mechanical system. The crankshaft is subjected to the combined action of centrifugal force from the rotating mass, periodically changing gas inertial force, and reciprocating inertial force, which causes the crankshaft to be subjected to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, have uniform operation, and good balance.

[0003] The shortcomings of existing technologies: In existing technologies, crankshaft testing usually involves workers placing the crankshaft on a support frame, installing the testing equipment, and manually rotating the crankshaft to test it. This method does not provide a stable fixation for the crankshaft testing equipment, and the equipment may move during rotation, affecting the test results. In addition, the support frame structure is simple and cannot be adjusted according to crankshafts of different sizes, reducing work efficiency. Utility Model Content

[0021] Furthermore, such as Figure 2 and Figure 3As shown, the fixing component 8 includes a fixing block 81, a connecting block 82 fixedly connected to the front end of the fixing block 81, and a connecting groove 83 opened at the front end of the connecting block 82. The size of the inner cavity of the connecting groove 83 is adapted to the cross-sectional height of the testing table 1. The connecting block 82 is movably connected to the outer surface of the testing table 1 through the connecting groove 83. According to the specific situation of the position adjustment of the movable support frame 4, the position of the connecting block 82 on the outer surface of the testing table 1 is moved through the connecting groove 83 to ensure that the crankshaft tester 10 corresponds to the position of the crankshaft surface.
