Abstract

The invention provides a rotary trimmer, and aims to solve the technical problem that a conventional grinding wheel trimmer is low in trimming precision. The rotary trimmer comprises a diamond pen, a swinging rod, a rack and a rotary driving device, wherein the diamond pen is fixed on the swinging rod; the rotary driving device is used for driving the swinging rod to rotate. The rotary trimmer is characterized in that the rotary driving device comprises a servo motor, a first main shaft, a harmonic reducer, a second main shaft and a tooth-shaped belt; a support arm is arranged at the upper end of the rack; the harmonic reducer is fixed at the left end part of the support arm; the servo motor is fixed at the right end part of the support arm; the input end of the harmonic reducer is connected with the first main shaft; the output end of the harmonic reducer is connected with the second main shaft; a driven pulley is arranged on the main shaft; a driving pulley is arranged on the output shaft of the servo motor; the driven pulley and the driving pulley are synchronously connected through the tooth-shaped belt; an adjusting arm is arranged on the second main shaft; and the swinging rod is connected with the adjusting arm.

Description

technical field [0001] The invention relates to the technical field of grinding wheel dressing of grinding machines, in particular to a rotary dresser. Background technique [0002] The existing grinding wheel dressing equipment mainly includes a diamond pen, a swing rod, a rotary oil cylinder and a frame. The diamond pen is installed on the swing rod, and the swing rod and the rotary oil cylinder are supported on the frame. turn. In the process of use, it is found that the dressing accuracy of the existing grinding wheel dresser is low. The main reasons are as follows: 1. In terms of transmission, the precision of the rotary oil cylinder is low, and it is easy to rotate, which causes the angle of the diamond pen to deviate. Affect the trimming size; 2. In terms of mechanical structure, the position of the diamond pen and the lifting device will shift due to mechanical vibration during long-term use, which will affect the trimming size. Contents of the invention [0003]...
