Abstract

The invention provides a centering chuck for a broaching machine and the broaching machine. The centering chuck for the broaching machine comprises a base, a bearing disc, a first adjusting mechanism, a plurality of bearing blocks and a plurality of second adjusting mechanisms. The base is provided with a first through hole and used for being connected with a workbench of the broaching machine, and the axis of the first through hole and the axis of a pull rod of the broaching machine are collinear. The bearing disc is connected with the base. The bearing disc is provided with a second through hole communicated with the first through hole. The first adjusting mechanism is connected to the base and the bearing disc at the same time and used for adjusting the position of the bearing disc relative to the base in the radial direction of the first through hole. The multiple bearing blocks are connected with the bearing disc, are arranged in the circumferential direction of the second through hole at intervals and are used for jointly bearing workpieces. The multiple second adjusting mechanisms are connected with the bearing disc and distributed in the circumferential direction of the second through hole at intervals, and the multiple second adjusting mechanisms are matched to adjust the position of the workpiece relative to the bearing block in the radial direction of the second through hole. Workpiece centering operation is convenient, time and labor are saved, efficiency is high, and machining cost is low.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a centering chuck for a broaching machine and a broaching machine. Background technique [0002] When the broaching machine performs a keyway operation on a workpiece such as a round pie-shaped gear, it is necessary to put the round pie-shaped gear on the auxiliary workbench of the broaching machine, and then process the keyway on the inner hole of the gear. In this process, it is necessary to artificially make the center line of the gear and the center line of the tie rod collinear. Due to the heavy weight of the workpiece, it is more difficult to find the center. The same batch of products needs repeated alignment, which is time-consuming and labor-intensive. ,low efficiency. [0003] Find through inventor's research, existing broaching machine has following shortcoming: [0004] The workpiece positioning is difficult, inconvenient to operate, time-consuming and labor-intensive, ...
