Description

Technical Field

[0001] The utility model relates to the technical field of crankshafts, in particular to a crankshaft defect detection platform. Background Art

[0002] The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsion loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work evenly and have good balance.

[0003] The crankshaft is one of the important components in the engine. It is responsible for converting the reciprocating motion of the piston into rotary motion, and it also needs to bear the power output of the engine. Therefore, the inspection of the crankshaft is very important for the safe operation and performance of the engine. The inspection of the crankshaft generally includes appearance inspection, size inspection, wear inspection, hardness inspection, balance inspection and other aspects. Through these inspections, the wear, cracks, deformation and other problems on the surface of the crankshaft can be detected to ensure that the size and shape of the crankshaft are consistent with the design requirements, the hardness meets the requirements, the balance is good, and the surface finish meets the requirements. If there is a problem with the crankshaft, a more detailed inspection or replacement of the crankshaft is required to ensure the safe operation and performance of the engine.

[0004] After searching, the Chinese utility model patent with publication number: CN113607743A discloses a crankshaft defect detection platform, which belongs to the field of visual inspection technology. It includes a workbench, a fixed clamping end, a mobile clamping end, a camera, a lighting lamp and an oil hole unblocking head. The fixed clamping end and the mobile clamping end are symmetrically arranged at both ends of the workbench, the mobile clamping end is slidably connected to the workbench, a three-jaw chuck is arranged on the opposite side of the fixed clamping end and the mobile clamping end, the camera and the oil hole unblocking head are arranged on the workbench, and the lighting lamp is arranged above the workbench. This device clamps the crankshaft through the fixed clamping end and the mobile clamping end, and the camera records the surface conditions of the crankshaft to quickly detect crankshaft defects. It solves the problems of large crankshaft size of large vehicles, difficulty in manual rotation detection, long detection time and high cost.

[0005] From the analysis of the above technical solutions, it can be seen that in the current crankshaft defect detection station, the detection elements are usually exposed on the outside, and external factors may cause harm or damage to the device. At the same time, the outside world is likely to interfere with the staff's inspection of the crankshaft. Utility Model Content
