Problems solved by technology

During processing, in order to prevent the workpiece from being elastically deformed by the radial force of the grinding wheel and affecting the processing accuracy, only a small amount of knife can be used, which prolongs the processing time, poor processing quality, and low efficiency; when the grinding wheel is working, its working surface is only used. part, reducing the utilization efficiency of the grinding wheel

Embodiment Construction

[0010] The present invention is described in further detail below in conjunction with accompanying drawing:

[0011] As shown in Figure 1 and Figure 2, on the 3M2150 cylindrical grinding machine, the electromagnetic centerless fixture is used to clamp two workpieces at the same time, and the grinding wheel cuts into the grinding method. The grinding wheel reciprocates at one time and can process two workpieces at the same time. This method It not only ensures the processing accuracy, but also improves the processing efficiency and reduces the cost.

[0012] The specific implementation steps are as follows:

[0013] 1) Install the positioning cylinder 1 on the workpiece shaft 7, and use the end surface of the grinding wheel 6 to grind the end surface of the positioning cylinder 1 smoothly. Positioning accuracy, so as to ensure processing accuracy;

[0014] 2) Adjust the fulcrum 4 and the fulcrum 5 of the electromagnetic centerless fixture, so that the two fulcrums are support...

Abstract

Disclosed is a method of processing two cylindrical inner ball tracks with one time of grinding, belonging to the technical field of grind machine processing. The steps of the method includes that a location barrel is mounted on a work piece, the cross section of the location barrel is flatly and smoothly grinded by using a working face of an abrasion wheel, two supporting points of a electromagnetism centerless fixture are adjusted to ensure the two supporting points of the electromagnetism centerless fixture to support the inner circles and outer diameters of two work pieces, the separation angle of the two supporting points is 110 degrees to 150 degrees, the electric voltage of a magnetic coil of the electromagnetism centerless fixture is adjusted, enabling the two work pieces and the location barrel to keep synchronous rotating, two grooves are trimmed on the working face of the abrasion wheel, the width and depth of the two grooves are inosculated with the inner circles and outer diameters of the two work pieces well installed, a work piece shaft and the abrasion wheel are started, and then the two work pieces are simultaneously ground and processed by using the abrasion wheel. The invention has beneficial effects that two work pieces can be processed simultaneously by using the method, guaranteeing the processing quality and improving processing efficiency.

Description

technical field [0001] The invention relates to the technical field of grinding machine processing, in particular to a method for grinding and processing two cylindrical inner raceways at one time. Background technique [0002] At present, when the 3M2150 cylindrical grinding machine with plunge grinding is used to process the inner raceway of the ultra-light series cylindrical bearing, only one product can be processed at a time. During processing, in order to prevent the workpiece from being elastically deformed by the radial force of the grinding wheel and affecting the processing accuracy, only a small amount of knife can be used, which prolongs the processing time, poor processing quality, and low efficiency; when the grinding wheel is working, its working surface is only used. Part of it reduces the utilization efficiency of the grinding wheel. Contents of the invention [0003] The purpose of the present invention is to provide a method for grinding and processing ...
