Problems solved by technology

[0003] The horizontal lathe has the function of cutting, but not the function of grooving. If grooving is required after turning the bushing, the grooving must be done on the grooving processing device, and the grooving cannot be done on the lathe.

Abstract

The invention discloses a keyway broaching device for a lathe. The keyway broaching device comprises a lathe frame, a screw rod, a screw rod driving mechanism, a pull rod, a broach driving mechanism, a broach, a broach frame fixing support, a broach frame and a broach bracket; the screw rod driving mechanism is fixed onto the lathe frame; the front end of the screw rod is fixed onto the screw rod driving mechanism, the rear end of the screw rod and the front end of the pull rod are fixed together and positioned on a same horizontal line, the rear end of the pull rod is fixed to the front end of the broach driving mechanism, the broach is fixed to the rear end of the broach driving mechanism, the broach frame fixing support is fixed onto the lathe frame and positioned behind the broach driving mechanism, the broach frame is fixed onto the broach frame fixing support, and the rear end of the broach is fixed onto the broach bracket. By the aid of the keyway broaching device for the lathe, the technical problem about how to use an integral frame of the lathe for broaching keyways can be solved.

Description

technical field [0001] The invention relates to a device for processing a key groove on a shaft sleeve, in particular to a device for processing a key groove by using the integral frame of a lathe. Background technique [0002] The shaft sleeve is mainly driven by the flat key during operation, and the above-mentioned flat key is placed in the keyway, so generally the shaft sleeve needs to be processed to draw the keyway. At present, there are mainly two processing methods for keyways: one is the method of upper and lower bolts; the other is the method of horizontally pulling keyways; the method of using bolts is mainly to process bushes with larger inner diameters. If the inner diameter of the bearing is smaller It is easy to damage the workpiece during processing; the way of using horizontal keyway is mainly to process the shaft sleeve with small inner diameter. The driving mechanism is a fixed frame that covers the shaft sleeve; the shaft sleeve is sleeved on the fixed f...
