The invention relates to the technical field of automobile engine gear manufacturing, in particular to an engine gear detection device and a detection method.
Background
In the gear manufacturing and producing industry of the automobile industry, two technical paths are mainly adopted, one is a carburizing and quenching gear grinding process, and the other is a hobbing, shaving and nitriding process.
The gear hobbing, shaving and nitriding process is one of the main modes of gear mass production, and has the advantages of high production efficiency and low cost. However, in the process of producing gears by adopting a shaving nitriding process, the following problems need to be solved: because the shaving is to cut and extrude the soft tooth surface after hobbing to generate plastic deformation, tiny burrs are easy to generate on the tooth surface and the tooth end, and the tiny burrs are only a few threads and are difficult to see by naked eyes; on the other hand, the gear production and circulation process is difficult to avoid the defect that the tooth surface is damaged in a concave-convex mode due to the fact that the gear surface is collided occasionally.
Because the automobile engine gear is produced in batch, the gear cannot be detected completely by high-precision gear detection equipment, and a sampling detection mode is usually adopted. Meanwhile, the defects are not easy to find, and abnormal sound is generated when the gear runs after being assembled, so that the service life and the quality of the gear are directly influenced.
Because the gears and shafts in the automobile industry are mostly assembled in an interference or transition mode, the assembly line is adopted, the gears are tightly arranged inside and outside, and if abnormal sound is found in the trial run process, the gear with burrs is difficult to find out from the gear set and to disassemble and replace, so that a large amount of time and labor are occupied, and the production efficiency is seriously influenced; meanwhile, the quality of the engine can be influenced by repeated disassembly and assembly. The existing single gear detection device is low in efficiency and high in labor cost, and meanwhile, people with long operation time can be tired, so that the detection quality is influenced.

If the detected workpiece position is pushed to be close to the standard wheel firstly and then the detected workpiece gear is installed, the danger coefficient to an operator is increased, so that the key point of the invention is that when the electric power source pushes the detected workpiece to move to the standard wheel in the early preparation work, the hand wheel is slowly rotated, and when the distance is adjusted, the detected workpiece gear slowly rotates, so that the gear pairs can be meshed with each other with sufficient time; even if only one gear can be adjusted at each time, when the rest gears are meshed with the standard wheel, each detected workpiece gear can rotate because of the gear, namely the meshing angle can be finely adjusted, so that one standard wheel on the same equipment can be matched with gears of multiple sizes by combining a replaceable gear bush, and the problem of difficulty in simultaneous transmission meshing interference is avoided.
