Inner ring grinding device and grinding method for rotating disc type bearing machining

Abstract

The invention discloses an inner ring grinding device and grinding method for rotating disc type bearing machining. The inner ring grinding device comprises a base, wherein a motor frame is welded toone side of the upper surface of the base, and the upper portion of the motor frame is connected with a speed reducer through bolts; a first motor which is in transmission connection with an input shaft is fixed to the side wall where the input shaft of the speed reducer is located through bolts, and a rotating seat is fixed on the other side of the upper surface of the base through bolts; and a supporting rod is movably connected with the interior of the rotating seat through a bearing, and a rotating disc is welded to the top of the supporting rod. According to the inner ring grinding deviceand grinding method, four bearing brackets can be controlled to move oppositely by only rotating a central rod, and the height and speed can be adjusted; the bearing brackets can clamp the outer wall, the upper surface and the lower surface of the bearing, and the fixing strength of the bearing is improved; and an upper movable frame is slidably connected in a lower supporting frame, and a movable block with the bottom provided with four pulleys is slidably connected inside a sliding frame, so that the stability of a milling cutter control structure is improved, and the machining precision ofan inner ring of the bearing is guaranteed.

Description

technical field [0001] The invention relates to the technical field of machining equipment, in particular to an inner ring grinding equipment and a grinding method for machining a turntable bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. The bearing can bear radial load and axial load at the same time. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. [0003] In the process of using the existing bearing inner ring grinding equipment, the fixing structure of the bearing is complicated, which affects the processing efficiency of the bearing inner ring. ring machining...
