Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that after broaching the inner wall of the workpiece for a long time, the broach will easily cause the friction between the broach and the inner wall of the workpiece to generate heat, which will cause the broach to be deformed or worn by heat, which will affect the quality of the broach and the use of the broach life, so it needs to be improved

Abstract

The invention relates to a lathe for spline housing broaching, and relates to the technical field of spline housing production. The lathe comprises a rack, a workbench and a broach, the workbench and the broach are located on the rack, the rack is provided with a first driving part used for driving the workbench to reciprocate in the height direction of the rack, and the rack is further provided with a second driving part used for driving the broach to reciprocate in the height direction of the rack; a workpiece and a workpiece fixing assembly are arranged on the workbench; and a cooling ring pipe is further arranged on the workbench and located on the periphery of the workpiece and the broach, a liquid outlet is formed in the side wall, facing the broach, of the cooling ring pipe in the circumferential direction of the cooling ring pipe, and the side wall of the cooling ring pipe communicates with a supply device used for supplying cooling liquid to the cooling ring pipe. The lathe has the effects of cooling the broach, prolonging the service life of the broach and ensuring the broaching quality of the broach.

Description

technical field [0001] The present application relates to the technical field of spline sleeve production, in particular to a lathe for spline sleeve embossing. Background technique [0002] The spline connection consists of a spline shaft and a spline sleeve. The spline sleeve is sleeved on the outside of the spline shaft. The spline shaft and the spline sleeve are used to transmit mechanical torque. The outer surface of the spline shaft is provided with a longitudinal keyway. A keyway corresponding to the keyway outside the spline shaft is provided to realize the synchronous rotation of the spline shaft and the spline sleeve; the broaching machine is a device for broaching the key groove inside the spline sleeve. [0003] The relevant authorized announcement number is the Chinese patent of CN201760660U, which discloses a screw type vertical internal broaching machine, including a bed, a workbench located in the bed, a broach, a lower clamping tool body and a lifting device...
