[0002] The spline connection consists of internal splines and external splines. Both internal and external splines are multi-tooth parts. The splines on the inner cylindrical surface are internal splines, and the splines on the outer cylindrical surface are external splines.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0020] Reference Figure 1-4, a processing device for a spline sleeve locking hole, comprising a support platform 1, a plurality of support columns are installed at the lower end of the support platform 1;

[0021] The punching mechanism includes an L-shaped frame 2 fixedly connected to the upper end of the support platform 1, a hydraulic telescopic rod 3 is installed at the lower end of the horizontal part of the L-shaped frame 2, a mounting plate 4 is fixedly connected to the telescopic end of the hydraulic telescopic rod 3, a connecting plate 17 is installed at the lower end of the mounting plate 4 by screws, and a plurality of punching heads are fixedly connected to the outer side of the connecting plate 17 at equal intervals;

[0022] The placing mechanism includes a rotating column 5 rotatably connected to the upper end of the supporting platform 1, and vertical plates 6 are fixedly connected to the left and right sides of the rotating column 5. A cylindrical groove 11 is provided through the upper end of each vertical plate 6, and a mounting cylinder 12 is placed in each cylindrical groove 11. A first opening 16 is provided at the inner bottom of each mounting cylinder 12, and a second opening 15 matching the first opening 16 is provided at the inner bottom of each cylindrical groove 11. A guide groove 13 is provided on the side wall of each cylindrical groove 11, and a guide block 14 corresponding to the guide groove 13 is provided on the inner wall of each mounting cylinder 12.

[0023] Among them, an electromagnet 7 is embedded at the upper end of the support platform 1, and the electromagnet 7 is located directly below the hydraulic telescopic rod 3. The electromagnet 7 is a high-power electromagnet, which will generate a huge magnetic force when in use;

[0024] It also includes a rotating mechanism, which is used to rotate the rotating column 5. The rotating mechanism includes a motor 9 installed at the lower end of the support platform 1. The lower end of the rotating column 5 passes through the support platform 1. The output shaft of the motor 9 and the lower end of the rotating column 5 are fixedly connected with a pulley 8. The two pulleys 8 are connected by a transmission belt 10.

[0025] In the utility model, in actual use, according to the spline sleeves of different radii, installation tubes 12 of different radii are selected (the installation tubes 12 have multiple models, and their inner diameters correspond to the outer diameters of the corresponding spline sleeves), and different connecting plates 17 and cutter head parts are selected according to the needs, and then the spline sleeve to be processed is inserted into the corresponding installation tube 12, and then the motor 9 is started, and the rotating column 5 is rotated 180° through the cooperation of the two pulleys 8, and then the electromagnet 7 and the hydraulic telescopic rod 3 are started, and the hydraulic telescopic rod 3 is extended to drive the cutter head part to move downward to achieve punching.
