Problems solved by technology

The above two methods cannot position the workpiece accurately and stably, the grinding feed rate cannot be accurately grasped, and there is no constant and effective driving source for the rotation of the workpiece itself, resulting in large dimensional differences of the processed workpiece, low shape and position accuracy, and rough surface high degree

Embodiment Construction

[0016] Specific embodiments of the present invention are described with reference to the accompanying drawings.

[0017] Processing method of the present invention is as shown in accompanying drawing 3. Place the cylindrical roller 2 on the electromagnetic centerless positioning mechanism of the machine tool, that is, the support 6, make one end surface of the cylindrical roller 2 contact with the magnetic pole 5, move the magnetizing switch, and one end surface of the cylindrical roller 2 is covered by the magnetic pole 5 Tight adsorption. Start the motor, the magnetic pole shaft and the grinding head shaft 8 rotate, and the rollers rotate together under the attraction force of the rotating magnetic pole. The center line (axis) of the roller and the center line of the grinding wheel are parallel to each other, and each rotates around its own center line. The grinding head shaft with the grinding wheel 1 moves in 8 directions, so that the end surface of the grinding wheel con...

Abstract

The invention discloses a method for performing precision grinding to the end surface of a super-large cylindrical roller. The method is as follows: one end surface of the cylindrical roller is closely adsorbed by a magnetic pole, the rolling surface of the cylindrical roller is positioned on a positioning mechanism which forms a certain angle to the vertical line, the roller rotates in the driving manner of rotating magnetic pole adsorption, the centre line of the roller is parallel to the rotating centre line of the grinding wheel while the roller and the grinding wheel rotate around the separate centre lines; a grinding head provided with the grinding wheel performs axial movement to grind; after the end surface of the roller is grinded, the grinding head moves backward, the processed workpiece is taken down; and another workpiece to be processed is arranged, the above steps are repeated to perform the next processing cycle. Compared with the prior art, the method of the invention can be used to position the workpiece stably and accurately; and the workpiece can operate steadily during processing, the grinding wheel is convenient for dressing, and the feeding position is easy to control.

Description

technical field [0001] The invention relates to a metal cutting processing method for bearing parts, and mainly relates to a precision grinding method for the end face of an extra-large cylindrical roller. Background technique [0002] Extra large cylindrical rollers usually refer to rolling elements with a nominal diameter greater than 60mm that are matched with extra large bearings. This type of roller end face grinding is ground by manual twisting on a simple device, as shown in Figure 1; or the end face is ground on a vertical grinding machine, as shown in Figure 2. As shown in accompanying drawing 1, the cylindrical roller 2 is placed on the V-shaped support seat 3, and the cylindrical roller 2 is manually pushed close to the grinding wheel 1. After contacting the grinding wheel 1, the cylindrical roller 2 is manually rotated to make it grind. Accompanying drawing 2 shows that the cylindrical roller 2 is placed on the disk 4, press the button, start the disk 4 and the ...
