Abstract

The invention discloses a pull-up type broaching machine, comprising: a machine body; a first driving mechanism comprising a first driving screw, a first driver, and a first screw nut sleeved on the first driving screw; a second driving mechanism comprising: a second driving screw, a second driver driving the second driving screw to rotate, and a second screw nut sleeved on the second driving screw; a first sliding table which is fixed to the first screw nut, has a processing station for fixing a workpiece, and controls the workpiece to perform vertical reciprocating movement under the drivingof the first screw nut to complete the processing; a second sliding table which is fixed on the second screw nut; a first chuck fixedly disposed relative to the machine body and located below the lower limit position of the first sliding table for holding one end of a broach; a second chuck fixedly connected to the second sliding table for clamping the other end of the broach. Evasion by the broach or the loading of the broach is carried out under the driving of the second sliding table.

Description

technical field [0001] The invention relates to a broaching machine, in particular to a pull-up type broaching machine. Background technique [0002] A broaching machine is a machine tool that uses a broach to process various inner and outer forming surfaces of a workpiece. According to the processing surface, the broaching machine can be divided into inner broaching machine and outer broaching machine. The inner broaching machine is used for broaching the inner surface, such as spline hole, square hole, etc., and the outer broaching machine is used for broaching the outer surface. According to the overall structure and distribution form, broaching machines are divided into horizontal and vertical. Among them, horizontal broaching machines are widely used and can process large workpieces, but occupy a large area; vertical broaching machines occupy a small area, but Tool travel is limited. The vertical broaching machine can be divided into pull-up type and pull-down type ac...
