Groove grinding wheel profile automatic detection and regulation trimming device and method

Abstract

The invention discloses a groove grinding wheel profile automatic detection and regulation trimming device and method. The device comprises a C-shaped support frame, a swing trimming frame, a swing driving mechanism, a trimming tool assembly and an analysis controller, wherein the swing driving mechanism is used for providing rotary power for the swing trimming frame, and the analysis controller is connected with a displacement detection assembly used for detecting displacement and a displacement regulation assembly used for adjusting the movement of the trimming tool assembly in a controllingmode; the C-shaped support frame is erected on the outer side of the swing trimming frame, the swinging driving mechanism is arranged at the upper end of the C-shaped supporting frame, connecting mandrels of the upper end of the swinging trimming frame and the upper end of the swinging driving mechanism penetrate through a rotating hole of the upper end of the C-shaped supporting frame, and a connecting mandrel of the lower end of the swinging trimming frame penetrates through a rotating hole of the lower end of the C-shaped supporting frame. The profile of a grinding wheel is detected on line, the trimming process is regulated in real time according to detection results, the purpose of automatic trimming on the profile of the wheel grinding is achieved, the trimming time is saved, the trimming cost is reduced, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of superhard material grinding wheel dressing and detection, and in particular relates to a dressing device and a use method for automatic detection and regulation of the grinding contour of a channel. Background technique [0002] The machining and final condition of the bearing ring raceway is the main factor affecting the accuracy and performance of the bearing. At present, the processing of the bearing groove generally adopts the microcrystalline corundum vitrified bond grinding wheel with a particle size of 80#~120# for plunge grinding. The grinding wheel dressing uses a diamond pen as a dressing tool, and uses the swing arm movement to trim the arc profile on the surface of the grinding wheel.

Problems solved by technology

However, the above two patents can only trim a whole arc on the surface of the grinding wheel, and cannot realize the complex contour trimming composed of multiple arcs, nor can it complete the adjustment of the arc curvature of the grinding wheel surface and the detection of the trimmed profile.

[0005] The Chinese invention patent "A grinding wheel dresser for deep groove ball bearing outer ring groove grinding machine" (application number: CN201610643588.1) discloses a grinding wheel dresser for deep groove ball bearing outer ring groove grinding machine, including a sliding seat, The upper bracket is slidably connected under the sliding seat, the coarse adjustment screw rod is connected between the sliding seat and the upper bracket, the lower bracket is arranged under the upper bracket, and the fine-tuning device is connected between the upper bracket and the lower bracket, which is detachably connected to the The positioning frame on one side of the sliding seat, the diamond pen connected to the lower bracket, the curvature standard block connected to the positioning frame and opposite to the diamond pen tip, and the dial gauge connected to the positioning frame; but the measured arc curvature is only The theoretical value cannot directly detect the trimmed profile, and it is
