Abstract

The invention provides a special fixture for knife edge angle square repair, and belongs to the technical field of measuring instrument maintenance. The special fixture for knife edge angle square repair solves the problems of repair difficultness and ineffectiveness due to the fact that no effective professional fixture for positioning is provided in the repair process of grinding equipment of existing knife edge angle squares. The special fixture for knife edge angle square repair comprises a base plate, a workpiece clamping device and a datum plane positioning device for eliminate positioning errors, wherein the datum plane positioning device includes an X-axis positioning portion, a Y-axis positioning portion and a Z-axis positioning portion, the workpiece clamping device includes an X-axis clamping portion and a Z-axis clamping portion, the X-axis clamping portion and the X-axis positioning portion are respectively arranged beside both sides of a workpiece and matches with each other to clamp the workpiece, and the Z-axis clamping portion and the Z-axis positioning portion are respectively arranged beside both sides of the workpiece and matches with each other to clamp the workpiece. According to the special fixture for knife edge angle square repair, a plurality of positioning portions and clamping portions are used for positioning the workpiece in three dimensions, so that the positioning errors are eliminated, and the stability of the workpiece in the repair process is ensured.

Description

technical field [0001] The invention belongs to the technical field of measuring tool maintenance, and relates to a special fixture for repairing a knife-edge square. Background technique [0002] The knife-edge square is a common measuring tool for measuring the verticality of the workpiece. It is used to measure and detect the verticality error between the reference plane and the side of the quilt. It is made of high-quality carbon tool steel. It has undergone multiple heat treatments during processing. The working surface is precision ground. Shaved. [0003] Existing knife-edge squares are composed of a long side and a short side, and the measuring surface is in the shape of a knife-edge, which can measure right angles more accurately. After long-term use, the measuring surface wears out, resulting in errors. At present, the commonly used repair method is to use grinding equipment to re-polish the measurement surface, but there is a lack of effective professional fixtur...
