Problems solved by technology

[0005] With the continuous development of the manufacturing industry, the precision of the processing technology is also continuously improved. In the existing technology, it is difficult to control the concentricity of the end cover and the oil bearing in the motor after pressing, and the concentricity deviation will directly affect the motor. Normal operation, reduce the use effect of the motor, greatly reduce the service life of the motor

Abstract

The invention provides a precision concentricity correcting tool. The tool achieves the function of correcting the concentricity between an oil bearing and a motor end cover through a correcting mandrel, achieves the positioning function by matching of an end cover base, a bearing block and a support rod, achieves the limit function by matching of a movable upper plate, a limit block and a fixed base plate, achieves the guiding function by matching of a linear guide bearing, a guide post and a limit stop, and achieves the tool resetting function by matching of a spring and a butterfly gasket.The tool can eliminate the gap between the oil bearing and the motor end cover, so that the oil bearing can be assembled into the motor end cover. The tool can further control the concentricity deviation between the oil bearing and the motor end cover to be small to ensure the assembly precision, and further ensure the normal operation of the motor and greatly prolong the service life of the motor.

Description

technical field [0001] The invention relates to a precision concentricity correction tool, in particular to a high-precision concentricity correction tool for assembling an oil-impregnated bearing and a motor end cover. Background technique [0002] Coaxiality is an important technical index for evaluating cylindrical workpieces, and the error of coaxiality directly affects the assembly and use of workpieces. However, when the axis of the measured element of the workpiece is particularly short, it is very difficult to evaluate its concentricity, which is usually evaluated by concentricity. [0003] The coaxiality error directly affects the matching accuracy and usage of the workpiece. The concentricity error reflects the different center of the circle center on the section is the concentricity, and the concentricity error is the degree of deviation of the circle center. [0004] Concentricity is a special form of coaxiality. When the measured element is the center of the ...
