Description

Technical Field

[0001] The utility model relates to the field of fixtures, in particular to a machining fixture for a bearing seat mounting hole. Background Art

[0002] The utility model patent with application number: CN202222896838.6 discloses a bearing seat mounting hole processing fixture, including a base and a clamping assembly for clamping the bearing seat, the base is penetrated with a plurality of through holes for the drill bit to pass through, one side of the base protrudes outward and is provided with two positioning columns for positioning the bearing seat, wherein the two positioning columns are arranged at intervals, and the positioning columns are adapted to the inner hole of the bearing seat; the clamping assembly includes a clamping block and a clamping bolt, one end of the clamping bolt passes through the through hole of the clamping block and is threadedly matched with the threaded hole on the base, so that the two ends of the clamping block are respectively pressed inwardly to the corresponding bearing seats sleeved on the two positioning columns. When the above technical solution is clamped and fixed, one end of the clamping bolt passes through the through hole of the clamping block and is threadedly matched with the threaded hole on the base, so that the two ends of the clamping block are respectively pressed inwardly to the corresponding bearing seats sleeved on the two positioning columns. When the milling machine processes the installation hole, it is only necessary to pass the drill bit of the milling machine through the through hole to process the installation hole of the bearing seat in the base to achieve accurate processing of the installation hole, thereby improving the accuracy of the bearing seat installation hole.
