Example Embodiment

[0023] The method of determining the size compensation amount for bearing processing is to determine the model of the workpiece to be processed and detect the standard part temperature T 2 And the workpiece temperature T after processing 1 , Select the pre-stored processing model and corresponding processing parameters according to the processed workpiece model, and according to the standard part temperature T 2 , Workpiece temperature T after processing 1 And the corresponding processing parameters are assigned to the bearing processing model, so that the operator knows the size of the processed part when the temperature of the processed part is the same as the standard part. Calculate the size compensation ΔL of the workpiece.

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

[0025] Preferably, the specific steps of the ...

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...
