Description

A Rotary Indexing Drilling Fixture

technical field

The utility model relates to a rotary indexing drill press fixture, which belongs to the technical field of mechanical processing.

Background technique

Machinery manufacturing is inseparable from metal cutting machine tools, and machine tool fixtures are one of the indispensable important process equipment to ensure the quality of machining, improve production efficiency, reduce labor intensity, reduce excessive requirements for workers' skills, and realize the automation of production process. There are mainly the following problems in the process of machining holes: 1. In the fitter drilling process, the machining accuracy of the workpiece is often clamped by bench vise. This is only a general fixture, and the shape of the workpiece that can be clamped is relatively single. Meet special needs; 2. When disassembling the workpiece, the workpiece is installed in the clamping device, and the disassembly of the clamping device takes a certain amount of time, thus reducing production efficiency; 3. When machining the inner hole, adjust the clamping position during the calibration process When there are two claws on the cylindrical surface, the workpiece will roll, causing the center line of the scribed hole to have an angular displacement. It is difficult to correct the workpiece and the machining accuracy cannot be guaranteed.
