Abstract

A multi-process special jig for a CNC to machine four-face holes comprises a base plate, a connecting plate and a jig main board, the base plate and the jig main board are connected together through the connecting plate, the base plate and the connecting plate are connected through M10 connecting bolts and screws, the connecting plate is connected with the jig main board through M5 connecting bolts, the jig main board is arranged on the upper surface of the connecting disc, the upper surface of the jig main board is a machining reference plane, pressing blocks are arranged on two opposite corners of the upper surface of the jig main board, and the pressing blocks are fixed to the jig main board through M8 fixing bolts. A vertical through locating hole is formed in the center position of the jig main board, threads are arranged on the inner side face of the locating hole, the locating hole corresponds to an M4 fixing bolt, and a machining hole is further formed in the side face of the jig main board. According to the multi-process special jig for the CNC to machine the four-face holes, the clamping mode of combining the pressing blocks and the locating hole is adopted, the ingenious design of the machining hole in the side face of the jig main board precisely completes machining of one side hole, machining of four processes is achieved, consumed time is little, and machining precision and production efficiency are improved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a multi-process special fixture for CNC machining four-sided holes and a clamping method. Background technique [0002] The earlier fixture type is mainly composed of moving jaws and fixed jaws, and the type is relatively simple. The defects of this type are: for the processing of four surfaces, three sets of fixtures are required to be clamped four times to complete the processing, which is cumbersome and time-consuming. It is easy to cause deformation of the workpiece during clamping, it is difficult to locate, and the processing size deviation is large. , very unstable, affecting the machining accuracy. Contents of the invention [0003] The present invention aims to provide a multi-process special fixture and clamping method for CNC machining of four-sided holes capable of controlling the deformation of workpieces and stabilizing the machining dimensions. [0004] ...
