[0002] Locking devices for spline rolling of metal parts refer to mechanical structures used to fix, clamp, or stabilize metal workpieces during the spline rolling process. Their core function is to ensure that the workpiece does not shift or vibrate during processing, thereby achieving high-precision spline forming. Current locking devices for spline rolling of metal parts cannot fix splines in a multi-directional and convenient manner, causing splines to slip off unexpectedly during the rolling process, leading to the failure of the spline rolling process. Furthermore, the locking process for splines is too cumbersome and complex, which is not conducive to the rapid locking of splines. Therefore, there is a need for a locking device for spline rolling of metal parts that can be locked in a multi-directional and rapid manner. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This locking device for spline rolling of metal parts comprises a nut, a housing, a first slide groove, a handle, a turntable, a torsion spring, a second slide groove, a column, a first slider, a fixing plate, a second slider, and a third slide groove. When locking the spline, the operator holds the handle and slides it in the first slide groove. The handle drives the turntable to rotate and the torsion spring to contract. The turntable drives the column to slide in the second slide groove, the column drives the first slider to move, the first slider drives the second slider to slide in the third slide groove, and the first slider drives the fixing plate to move. After the spline is installed, the operator releases the handle, the torsion spring returns to its original position, causing the turntable to rotate in the opposite direction and finally fix the spline. Finally, the operator rotates the nut on the handle to fix the handle. This reduces the spline locking process, facilitates quick and multi-directional locking of the spline, prevents the spline from accidentally slipping off during rolling, thus preventing rolling failure and improving the stability of the locking device.

[0012] 2. This locking device for spline rolling of metal parts consists of a rolling die, a U-shaped frame, a connecting block, threaded plates, a threaded rod, and a rotating handle. When adjusting the rolling position, the operator rotates the rotating handle to drive the threaded rod to rotate. Due to the opposite threads on the threaded rod, the threaded rod pushes the two threaded plates to move towards each other. The threaded plates drive the connecting block and the U-shaped frame to move, and the U-shaped frame drives the rolling die to move. This facilitates the rolling of splines of different sizes and improves the versatility of the locking device. Attached Figure Description

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a locking device for spline rolling of metal parts, including a machine tool 1, a second support plate 15 fixedly connected to the machine tool 1, two telescopic rods 16 fixedly connected to the second support plate 15, a limit block 18 installed at the top of the telescopic rod 16, and a spring 17 sleeved on the outside of the telescopic rod 16. Because of the limit block 18, when installing the spline, the operator lifts the limit block 18, which pulls the telescopic rod 16 and the spring 17 to extend. After one end of the spline is installed on the second support plate 15, the operator lowers the limit block 18, which facilitates quick positioning of one end of the spline and prevents the spline from accidentally shaking during processing, resulting in inaccurate rolling and improving the stability of the locking device.

[0020] Machine tool 1 is equipped with two U-shaped frames 19, and motors 20 are fixedly connected to the U-shaped frames 19. A rolling die 21 is mounted on one side of each motor 20 and is fixedly connected to the U-shaped frames 19. Because of the rolling die 21, when performing rolling processing on splines, the operator starts the motors 20 on the two U-shaped frames 19. The motors 20 drive the rolling die 21 to rotate, facilitating rapid and automatic rolling processing of the splines, saving manpower and resources, and improving the efficiency of rolling processing. A first support plate 2 is fixedly connected to machine tool 1. A first bearing 3 is mounted on one side of the first support plate 2. A housing 4 is fixedly connected to one side of the first bearing 3. A first groove 5 is provided on the housing 4. A handle 6 is snapped onto the slide 5, and a nut 29 is threaded onto the handle 6. A turntable 7 is fixedly connected to the bottom of the handle 6. The turntable 7 is snapped onto the inner wall of the outer shell 4. A torsion spring 8 is installed on one side of the turntable 7. One end of the torsion spring 8 is fixedly connected to the outer shell 4. Two fourth slides 23 are opened on the machine tool 1. A connecting block 22 is snapped onto the inner wall of the fourth slide 23. The connecting block 22 is fixedly connected to the fourth U-shaped frame 19. A threaded plate 24 is installed on the bottom side of the connecting block 22. A threaded rod 25 is threaded onto the threaded plate 24. The threaded rod 25 has threads in opposite directions. One end of the threaded rod 25 is snapped onto the machine tool 1. A handle 27 is fixedly connected to the end of the threaded rod 25 that extends out of the machine tool 1.

[0021] A second bearing 26 is installed on one side of the threaded rod 25. The second bearing 26 is fixedly connected to the machine tool 1. The second bearing 26 limits the movement of the threaded rod 25 while ensuring its normal rotation, thus improving the stability of the threaded rod 25 during rotation. Four second slide grooves 9 are provided on the turntable 7. A column 10 is engaged with the inner wall of the second slide groove 9. A first slider 11 is fixedly connected to one end of the column 10. A fixing plate 12 is installed on one side of the first slider 11. A third slide groove 14 is provided on the inner wall of the outer shell 4. A second slider 13 is engaged with the inner wall of the third slide groove 14. The second slider 13 is fixedly connected to the first slider 11. Four anti-slip pads 28 are installed on the bottom side of the machine tool 1. The four anti-slip pads 28 are respectively arranged at the four corners of the bottom side of the machine tool 1. The anti-slip pads 28 prevent the bottom side of the machine tool 1 from directly contacting the ground, preventing the machine tool 1 from accidentally sliding sideways, which could lead to errors or failures in the rolling of the spline, thus improving the overall stability of the locking device.

[0022] The working principle of this utility model is as follows: When locking the spline, the operator holds the handle 6 and slides it in the first slide groove 5. The handle 6 drives the turntable 7 to rotate and causes the torsion spring 8 to retract. The turntable 7 drives the column 10 to slide in the second slide groove 9. The column 10 drives the first slider 11 to move. The first slider 11 drives the second slider 13 to slide in the third slide groove 14. The first slider 11 drives the fixing plate 12 to move. After the spline is installed, the operator releases the handle 6. The torsion spring 8 returns to its original position, causing the turntable 7 to rotate in the opposite direction and finally fix the spline. Finally, the operator rotates the nut 29 on the handle 6 to fix the handle 6. The operator then lifts the limiting block 18, which pulls the telescopic rod 16 and spring 17 to extend. After one end of the spline is installed on the second support plate 15, the operator lowers the limiting block 18. When adjusting the rolling position, the operator rotates the handle 27 to drive the threaded rod 25 to rotate. Because the threads on the threaded rod 25 are in opposite directions, the threaded rod 25 pushes the two threaded plates 24 to move towards each other. The threaded plates 24 drive the connecting block 22 and U-shaped frame 19 to move. The U-shaped frame 19 drives the rolling die 21 to move. When performing rolling processing on the spline, the operator starts the motors 20 on the two U-shaped frames 19. The motors 20 drive the rolling die 21 to rotate.
