Description
Technical Field
The utility model relates to a positioning and aligning device for machining a three-jaw chuck guide groove, and belongs to the technical field of machining.
Background
The precision of three guide slots of the three-jaw chuck can directly influence the self-centering precision of the three-jaw chuck, the existing working mode is to directly interpolate and mill the three guide slots by using a numerical control machine tool, and when the three guide slots are directly interpolated and milled by using the numerical control machine tool, the positioning and alignment of the three-jaw chuck guide slots are not accurate enough because of interpolation and processing and the straightness of the guide slots is out of tolerance, the precision of the three-jaw chuck guide slots cannot meet the use requirement.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a positioning and aligning device for processing the guide groove of the three-jaw chuck, which is characterized in that a bottom plate is abutted against a first processed guide groove, a part is rotationally aligned according to a surface A, the surface A is parallel to a linear axis of a machine tool, and the two remaining guide grooves of the three-jaw chuck are sequentially processed by using the same linear axis of the machine tool, so that the straightness accuracy of the guide groove can be effectively ensured, and the accuracy can meet the use requirement.
The technical scheme adopted for solving the technical problems is as follows: the positioning and aligning device for machining the three-jaw chuck guide groove comprises a vertical plate and a bottom plate, wherein the vertical plate in the vertical direction is in an obtuse triangle shape, and the obtuse angle of the vertical plate is positioned at the position below the right; the bottom of the vertical plate is provided with a rectangular plane bottom plate in the horizontal direction, and the plane of the bottom plate is a B plane; on the right side adjacent to the surface B, the inclined side of the vertical plate is the surface A; the included angle between the surface A and the surface B is 120+/-1', and two symmetrical holes I and two symmetrical holes II are arranged in the plate surface of the vertical plate.
The beneficial effects of the utility model are as follows: the three-jaw chuck has the advantages that the indexing alignment of three guide grooves of the three-jaw chuck is realized, the positioning alignment of the guide grooves of the three-jaw chuck is accurate, interpolation processing is not needed, the three-jaw chuck is processed by the same linear shaft, the straightness accuracy of the guide grooves is ensured on the basis of ensuring the 120-degree indexing accuracy of the three guide grooves, the accuracy of the three-jaw chuck can meet the use requirement, and the three-jaw chuck is convenient to use, high in practicability and good in use effect.
