Clamping tooling for three bearing holes on bearings for fine boring rv reducers

Abstract

The invention relates to a clamping tool for finely boring three bearing holes in a bearing for an RV speed reducer. The clamping tool comprises a base; the middle of the upper surface of the base is upwards provided with a circular truncated cone extending into a shaft hole of the bearing; a bolt hole passing through the upper end surface of the circular truncated cone and the lower bottom of the base is formed in the circular truncated cone; the outside of the circular truncated cone is sleeved with an expansion sleeve matched with the outer side surface of the circular truncated cone; the expansion sleeve is fixed together with the base by a hold-down bolt; three through holes are uniformly distributed in the base along the axial direction of the circular truncated cone; guide posts extending into the bearing holes in the bearing are placed in the through holes; two sides of the base are provided with baffles; a horizontal through hole for placing a dial indicator is formed in the upper part of each baffle; and a measuring head of each dial indicator is in contact with the outer side wall of the bearing. Due to the adoption of the design based on product structure and application condition, the three bearing holes in an inner ring assembly of the bearing can be finely bored, the precision consistence of the bearing holes with the same graduation is guaranteed, and the clamping tool is short in machining time, high in efficiency, capable of guaranteeing the assembly precision and good in application prospect.

Description

technical field [0001] The invention relates to the technical field of bearing processing for an RV reducer, in particular to a clamping tool for fine boring three bearing holes on a bearing for an RV reducer. Background technique [0002] In the mechanical process of the bearing inner ring for the robot RV reducer, especially the fine boring process of the bearing inner ring assembly, the inner ring is assembled and used in groups with multiple parts. Therefore, there are high requirements for the positional accuracy and dimensional accuracy of the three bearing holes of the bearing inner ring assembly, and higher requirements for the consistency accuracy among the three bearing holes of the inner ring assembly. At present, the existing processing methods of bearing inner ring components for robot RV reducers basically use coordinate grinding, slow wire, drilling molds, etc., which have low processing efficiency, high overall cost, long processing cycle, and errors It will...
