Problems solved by technology

[0002] like figure 1 The rotors shown are widely used in products such as vane pumps, automotive steering pumps, and automotive air-conditioning compressor rotors. The key precision of the rotor is the flatness of the two sides of the radial grooves on the outer peripheral surface of the rotor. Therefore, in the rotor processing After forming, it is necessary to grind the groove of the rotor. The existing rotor groove grinding machine grinds the rotor groove through the grinding wheel, and then the existing rotor is difficult to locate during the processing, and the rotor workpiece often appears in the feeding process. The groove cannot correspond to the grinding wheel precisely, the grinding wheel cannot be inserted into the rotor groove, and the grinding wheel is easy to touch the peripheral surface of the rotor, causing the rotor to wear

Abstract

A rotor slot grinding machine comprises a grinding machine body, a grinding wheel, a workpiece fixture mechanism, a workpiece positioning mechanism and a grinding wheel dressing mechanism; the grinding wheel is installed on a grinding wheel spindle in a sleeving mode, the grinding wheel spindle is supported and installed on a grinding wheel box through a bearing, and the grinding wheel box is fixedly installed on the grinding machine body; the workpiece fixture mechanism and the grinding wheel dressing mechanism are arranged on the two sides of the grinding wheel box correspondingly; and the workpiece positioning mechanism is installed on the grinding wheel box. According to the rotor slot grinding machine, clamping and angle dividing of a workpiece can be achieved through the workpiece fixture mechanism, and accordingly, the grinding wheel can accurately grind a rotor slot; and the two end faces and the excircle face of the grinding wheel can be dressed through the grinding wheel dressing mechanism, and thus, the precision of the end faces and the excircle face of the grinding wheel is ensured. The rotor slot grinding machine is reasonable in structural layout, high in machining efficiency and precise in positioning, and the excircle face of a rotor cannot be damaged.
