Description

Technical Field

[0001] The utility model relates to a spline pipe processing tool and belongs to the technical field of tooling. Background Art

[0002] In the field of automotive parts processing technology, both rear-wheel drive and four-wheel drive vehicles will use the transmission shaft, and the transmission shaft will use the spline tube. During the processing of the spline tube sleeve, a punch press is required to process the locking hole on the spline tube sleeve. The current processing method of the spline tube sleeve is to lock the spline tube sleeve on the punch press, and then use the punch press to complete the processing. During the processing, there is sliding friction between the tube and the tooling, and the friction resistance is large, which leads to large thermal deformation of the metal and tube rupture, low yield rate, high processing difficulty, and low precision.

[0003] The utility model patent with application number CN201922077310.4 discloses a new type of spline tube processing clamping device for gear shaping machine, wherein the top end of the base body is provided with a top clamping device, and the bottom end of the base body is provided with a tail end fixing device; the top end clamping device includes an ER elastic collet and an ER locking nut, and the ER locking nut is arranged on the outside of the ER elastic collet and is threadedly connected with the ER elastic collet; the tail end fixing device includes a tail end support tube and a tail positioning device, and the tail positioning device is arranged at the bottom end of the tail end support tube, and the top end of the tail positioning device is provided with a top, and the tail positioning device is provided with a plurality of drainage holes; the base body, the top end clamping device and the tail end fixing device are all arranged coaxially. The tail support can be disassembled and replaced according to the length and outer diameter of the workpiece, and the length of the support tube can be replaced according to the length of the workpiece. The front end of the base body adopts high-precision ER elastic collet and ER locking nut, and different ER collets can be replaced according to the diameter of the workpiece, and the holding range can be adjusted. However, the clamping operation of the spline tube is cumbersome, and the gear shaping operation will cause large thermal deformation or even rupture of the spline tube, resulting in a low yield rate, great processing difficulty and low precision.
