Embodiment Construction

[0020] The embodiment of the composite dressing device in the present invention: figure 1 with figure 2 As shown, it includes a machine base 2 and a hollow main shaft 4 assembled on it. A pair of rolling bearings 8 spaced up and down is sleeved on the outer circumference of the hollow main shaft 4 so that the hollow main shaft 4 is rotated and assembled on the machine base through the rolling bearing 8 around a vertically extending axis. 2, and between the two rolling bearings 8 is provided with a bearing spacer 7 sleeved on the outer circumference of the hollow main shaft 4, so as to maintain the relative position of the two rolling bearings 8 through the bearing spacer 7. The bottom of the hollow main shaft 4 is connected to a driving motor 1 through a transmission belt 3, and the driving motor 1 is fixed on the right side of the machine base 2.

[0021] A wireless power transmission device is also installed between the hollow main shaft 4 and the base 2. The wireless power tr...

Abstract

The invention discloses a composite dressing device. The composite dressing device comprises a machine base, a cup-shaped grinding wheel and a spindle. The spindle is rotatably assembled on the machine base around the axis extending in the vertical direction. The composite dressing device further comprises an ultrasonic vibration system which is used for driving abrasive particles in the cup-shaped grinding wheel to vibrate at a high frequency. The ultrasonic vibration system is connected with the cup-shaped grinding wheel, so that longitudinal and radial coupled vibration, mainly radial vibration, of the cup-shaped grinding wheel is generated; by the adoption of the vibration form, the impacting and grinding effect of the abrasive particles is improved, and the area of the cup-shaped grinding wheel and the area of the grinding wheel to be dressed are increased. Under the action of the ultrasonic vibration, the impacting and grinding force of the abrasive particles to the grinding wheel to be dressed is improved, and the grinding progress is accelerated; the dressing efficiency of the grinding wheel to be dressed is improved in the way of combining ultrasonic dressing with cup-shaped grinding wheel dressing, and the problems that in the prior art, the dressing efficiency of a superhard grinding wheel is low, and the loss of a dressing tool is large are solved.

Description

Technical field [0001] The invention relates to a composite dressing device. Background technique [0002] Super-hard grinding wheel has the characteristics of high hardness, good strength, strong abrasive cutting force, wear resistance, etc., so after the super-hard grinding wheel is blunt, its dressing becomes very difficult. It is difficult to achieve the ideal surface morphology and geometric accuracy of the grinding wheel with traditional dressing methods, especially when the super-hard grinding wheel is trimmed with ordinary diamond pens or diamond roller lateral feed, the bus bar of the super-hard grinding wheel is easily worn and becomes a slash. Or convex curve, and because the diamond pen wears faster, the shape and dimensional accuracy of the superhard grinding wheel to be repaired is low; the diamond roller cannot simultaneously shape and sharpen the superhard grinding wheel. However, the emerging electric machining dressing, laser dressing, and ELED online dressing ...
