Embodiment Construction

[0023] The method of determining the size compensation amount in bearing processing is to determine the type of workpiece to be processed and detect the temperature T of the standard part 2 and workpiece temperature T after processing 1 , select the pre-stored processing model and the corresponding processing parameters according to the workpiece model to be processed, and according to the standard part temperature T 2 , Workpiece temperature T after processing 1 and the corresponding processing parameters to assign values ​​to the bearing processing model, so that the operator can know the size of the processed part when the temperature of the processed part is the same as that of the standard part. Calculate the workpiece size compensation ΔL.

[0024] Preferably, the processing model is a temperature compensation model; the processing parameters are the coefficient of thermal expansion α, the correction coefficient k and the diameter D of the workpiece.

[0025] Preferab...

Abstract

The invention belongs to the technical field of bearing machining, and particularly relates to a dimension compensation quantity determining method for bearing machining. The dimension compensation quantity determining method for bearing machining comprises the steps that the type of a to-be-machined workpiece is determined; the standard workpiece temperature T2 and the machined workpiece temperature T1 are detected; a pre-stored machining model and corresponding machining parameters are selected according to the type of the to-be-machined workpiece; and the bearing machining model is assignedaccording to the standard workpiece temperature T2, the machined workpiece temperature T1 and the corresponding machining parameter, so that the dimension compensation quantity of the to-be-machinedworkpiece is obtained through calculation. By adoption of the dimension compensation quantity determining method for bearing machining, machining dimension compensation quantity errors caused by experience-based judgment by operators are avoided, the machining precision and machining efficiency of bearings are improved, the machining repair rate of the bearings is greatly decreased, and the numberof rejected products is reduced; and operation is easy.

Description

technical field [0001] The invention belongs to the technical field of bearing processing, and in particular relates to a method for determining a size compensation amount in bearing processing. Background technique [0002] During the bearing machining process, the workpiece friction generates heat, which leads to thermal expansion of the bearing. If the temperature difference is not considered and the temperature compensation conversion is performed, machining errors will inevitably occur. In the prior art, in order to avoid errors caused by machining temperature changes, the operator The amount of processing size compensation is often judged by experience, and the size compensation amount of the processed part is roughly given based on the operator's own experience according to the temperature difference (when the temperature of the processed part is higher than the standard part, the operator should process to the upper limit of the size), and the operation Some have ric...
