Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a fixture for boring bearing seats. Background Technology

[0002] In the field of mechanical manufacturing, bearing housings are key support components in various mechanical equipment, and their machining accuracy directly affects the overall operating performance and stability of the equipment. In particular, the boring process of bearing housings is of paramount importance, because high-precision boring can ensure the tightness, concentricity, and rotational accuracy between the bearing and the shaft, thereby reducing vibration and wear during equipment operation and extending the service life of the equipment.

[0003] Traditional bearing housing boring fixtures cannot stably restrict the bearing housing's position within the housing space from all angles when positioning the bearing housing. As a result, the bearing housing is prone to placement angle deviation or positional offset in the initial stage of machining. This causes the actual axis of the boring hole to deviate significantly from the ideal design axis, ultimately resulting in the produced bearing housing being unable to meet the requirements of high-precision mechanical assembly.

[0004] Based on the above, this utility model proposes a fixture for boring bearing seats, which can effectively solve the above problems. Utility Model Content
