Abstract
A boring positioning fixture comprises a positioning component and a clamping component. The positioning component comprises a base and a circular positioning platform vertically arranged on the base, and the base is provided with installing holes and connected with a machine tool workbench through screws. The clamping component is a pressing plate installed on the periphery of the circular positioning platform, the pressing plate is connected with the base through a bolt, the pressing plate can rotate around the axis of the bolt, an elastic device is arranged on the working part of the bolt in a sleeved mode, a limiting groove is formed in the bottom of the pressing plate, and the limiting groove in the pressing plate is matched with a limiting device beside the clamping component after the pressing plate rotates to a certain angle around the axis of the bolt. The boring positioning fixture is simple in structure, reliable in positioning and capable of guaranteeing product quality and production efficiency in the using process and achieving the purpose of fast, conveniently and safely mounting and dismounting a workpiece, the workpiece can enter the accurate position better, the time taken to align the workpiece manually is shortened, the working conditions of workers are improved, and product cost is reduced for enterprises.
