Orienting device of broaching machine

Abstract

The invention relates to an orienting device of a broaching machine. The orienting device comprises a clamping cutter body, a top cap, at least two orienting pins and an orienting key. The clamping cutter body comprises a first cavity, and the first cavity is used for allowing a front handle of a broach to penetrate. The top cap is fixedly connected with the clamping cutter body and arranged at the first end of the clamping cutter body, and the first end is the end, close to a to-be-milled part, of the clamping cutter body. One end of each locating pin is fixedly connected with the top cap, and splines are arranged at the other ends of the locating pins. The locating key is arranged on the inner wall of the first cavity and / or the second cavity and is used for guiding the front handle of the broach to move axially. According to the orienting device of the broaching machine, in the part broaching process, the process that an operator achieves alignment by hand and achieves automatic alignment through the orienting structure is not needed any more, potential safety hazards are eliminated, the orienting precision is guaranteed, and part production and machining are qualified.

Description

technical field [0001] The invention relates to an orientation device, in particular to a broaching machine orientation device. Background technique [0002] Before the broaching process of the part, the operator needs to use one hand to align the spline groove in the part with the guide tooth on the front handle of the broach, and then operate the equipment with the other hand. The operator's line of sight needs to be paid attention to at the same time equipment and parts. There are potential safety hazards, but they cannot be avoided. Moreover, there are errors and instability in the orientation due to manual alignment, which will cause the tooth side of the part to be strained during the broaching process, resulting in scrapping and quality problems. Contents of the invention [0003] In order to avoid potential safety hazards and quality phenomena in the processing process, the present invention provides a broaching machine orientation device, which can ensure the re...
