According to the device, a traditional production mode of blank preparing, electroplating, machining and detection is changed into a production mode of blank preparing, thermal spraying, machining and detection, the machining mode is more environmentally friendly, environmental pollution is relieved, fixed-point spraying, machining and detection can be carried out on any selected surface of a part, metal electroplating and detection time is saved, and therefore the production cost is saved.

Description

technical field [0001] The invention relates to a motorcycle crankshaft processing equipment, more precisely, an integrated thermal spraying, processing and testing device for the motorcycle crankshaft. Background technique [0002] The crankshaft is one of the most important parts in the motorcycle engine. The crankshaft is one of the most important parts in the motorcycle engine. It cooperates with the connecting rod to convert the reciprocating linear motion of the piston into the continuous rotary motion of the crankshaft. The transmission transmits power to the wheels. The crankshaft is subjected to complex forces during operation, and it is subjected to loads such as bending, torsion, and compression that generally change periodically. In addition, the shape of the crankshaft is complex, and there are many processing techniques and surfaces, so the processing procedures are relatively cumbersome.

Problems solved by technology

The crankshaft is subjected to complex forces during operation, and it is subjected to loads such as bending, torsion, and compression that generally change periodically. In addition, the shape of the crankshaft is complex, and there are many processing techniques and surfaces, so the processing procedure is relatively cumbersome.

The traditional crankshaft processing process has the following problems. Problem 1: In order to achieve wear-resistant and anti-corrosion of certain rotating surfaces, the traditional crankshaft processing needs to be electroplated with a layer of heavy metals such as chromium and nickel on the surface of the crankshaft. The traditional electroplating is mainly the overall electroplating or the need for insulation The local electroplating of the layer will cause serious heavy metal pollution, and the redundant electroplating layer or insulating layer needs to be removed after processing, which increases the workload of the machine tool and the operator, and increases the production cost; problem 2: the crankshaft production is a multi-process assembly line, The production process is relatively scattered, which not only increases the number of equipment, the number of operators and the floor space, wastes manpower and material resources, but also increases the number of workpiece installations, which is not conducive to ensuring the positional accuracy between surfaces

The overall plating metal removal rate is high, and the partial plating needs to remove the insulating layer, both of which have shortcomings
