Oscillating bar bearing structure of arc trimmer

Abstract

The invention provides an oscillating bar bearing structure of an arc trimmer. By means of the oscillating bar bearing structure, the upper end and the lower end of an oscillating bar can be on the same vertical axis, so that machining precision of a trimmer base cannot influence movement trails of a diamond pen and the manufacturing cost of the arc trimmer is low. The oscillating bar bearing structure comprises the trimmer base, the oscillating bar and the diamond pen, the middle of the oscillating bar is provided with the diamond pen, and the upper end and the lower end of the oscillating bar are located an upper end installation cavity and a lower end installation cavity of the trimmer base respectively. The oscillating bar bearing structure is characterized in that the convex position of the upper end and the convex position of the lower end of the oscillating bar are respectively provided with a cone frustum hole with inwards concave closing-in port, a steel ball structure is distributed in the cone frustum hole and comprises an upper steel ball and a lower end steel ball, the outer ring portion of an upper gland is fixedly connected with the upper wall of the upper end installation cavity of the trimmer base, and the center of the lower portion of the upper gland is provided with a cone frustum upper hole with an inward concave closing-in port.

Description

technical field [0001] The invention relates to the structural technical field of an arc trimmer, in particular to a swing rod support structure of an arc trimmer. Background technique [0002] A diamond pen is arranged in the middle of the swing rod of the existing arc dresser, and the upper and lower ends of the swing rod are respectively supported in the corresponding bearing installation cavity through bearings. The upper bearing and the lower bearing need to be on the same axis. When the upper bearing and the lower bearing are not on the same axis, the movement track of the diamond pen in the middle of the swing rod will deviate, resulting in defective products of the grinding wheel to be dressed. Therefore, the machining accuracy of the bearing installation cavity of the dresser base is required to be high , so that the machining cost and manufacturing cost of the arc dresser are high. Contents of the invention [0003] In view of the above problems, the present inv...
