Servo-drive diamond pen arc trimmer

Abstract

The invention discloses a servo-drive diamond pen arc trimmer. A servo motor is connected with a clearance-free precise speed reducer, the clearance-free precise speed reducer is connected with a trimming oscillating rod through a rotation-clearance-free coupler, a pair of angle contact bearings are arranged in an integrated base, a rotating shaft fixed by the angle contact bearings is arranged in the integrated base, the integrated base is connected with the trimming oscillating rod through the rotating shaft, a trimming rod is arranged on the trimming oscillating rod, a diamond pen is positioned on the trimming rod, and a numerically-controlled system is connected with the servo motor through a wire. The clearance-free precise speed reducer, the rotation-clearance-free coupler, the trimming oscillating rod, the trimming rod and the rotating shaft can form a rotating main body. The numerically-controlled system can control the servo motor to drive the rotating main body to do rotating motion with the integrated base as the base. The servo-drive diamond pen arc trimmer is high in trimming accuracy, long in service life, high in producing and using efficiency and good in popularization value.

Description

Technical field: [0001] The invention relates to an arc trimmer, in particular to a servo-driven diamond pen arc trimmer. Background technique: [0002] In the existing technical field, the circular arc trimmers of general grinding machines are driven by oil cylinders or geared motors. Due to the influence of the quality of the oil cylinders or the gear clearance of the geared motors, the arc trimmed on the grinding wheel will have silk traces, Vibration, high roughness, arc deformation and other problems. In general, the circular arc dresser of the grinding machine is designed to install precision diagonal contact bearings at both ends of the trimming swing rod. Due to the assembly error of the bearing seats at both ends, the actual concentricity of the bearings at both ends after the bearings are installed is It is difficult to ensure that the trimmed arc is a deformed arc, which reduces the accuracy of the arc. [0003] The information disclosed in this Background secti...
