Embodiment Construction

[0021] The specific implementation of the present invention will be further described below in conjunction with accompanying drawing:

[0022] like figure 1 As shown, the sharpening device of the present invention includes CO 2 Laser 1, fixed bracket 2, focusing lens 3, pulley 4, frequency modulation motor 5, spindle 6, grinding wheel frame 8 and three-phase asynchronous motor 9. CO 2 Laser 1 adopts the sealed CO produced by Shanghai Laser Research Institute. 2 laser. Wheel frame 8 is a flat car with 4 small wheels 10, and three-phase asynchronous motor 9 is connected with two small wheel shafts arranged side by side in 4 small wheels 10. Resin bond grinding wheel 7 adopts resin bond Al with a particle size of 100 2 o 3 Grinding wheel. The main shaft 6 is supported on the grinding wheel frame 8 by two bearings, and the resin bond grinding wheel 7 and the belt pulley 4 are installed at the two ends of the main shaft 6 respectively. The four small wheels 10 are driven by...

Abstract

The present invention belongs to the field of mechanism engineering technology. The grinding wheel sharpening apparatus includes CO2 laser, fixing rack, focusing lens, belt wheel, frequency regulating motor, main shaft, grinding wheel frame, and triphase asynchronous motor. Through grinding wheel sharpening digital simulation to obtain the proportional relation between the groove depth and E1, selecting output power and light spot diameter of CO2 laser to determine the linear speed of the grinding wheel, regulating output power and light spot diameter of CO2 laser, regulating the rotation speed of the frequency regulating motor to regulate the surface linear speed of the grinding wheel, regulating the rotation speed of the triphase asynchronous motor to regulate the axial speed of the grinding wheel, and regulating performance parameters of the laser to control the sharpening effect precisely, ideal grinding wheel may be obtained.

Description

technical field [0001] The invention relates to a resin bond grinding wheel sharpening device and method, in particular to a continuous laser sharpening resin bond grinding wheel device and method, belonging to the technical field of shaping of processing tools in mechanical engineering. Background technique [0002] At present, there are many methods for sharpening resin bonded grinding wheels, such as free abrasive extrusion and sharpening, corundum block cutting and sharpening, grinding and sharpening, and hydraulic jet sharpening. The sharpening parameters of these mechanical sharpening methods are not easy to control, and it is easy to over-sharpen the grinding wheel, causing a large number of abrasive particles on the surface of the grinding wheel to fall off, affecting the sharpening effect and the service life of the grinding wheel. Moreover, for dense grinding wheels such as resin or metal bonds, the height fluctuation of the bond surface is an important factor that...
