[0016] like Figure 1 and Figure 2 As shown, an intermittent punching device for wheel hub processing includes a workbench 1, wherein two bearing plates 2 are provided on the workbench 1, a base 3 is provided between the two bearing plates 2, both sides of the base 3 are rotatably connected with the bearing plates 2 through a rotating shaft 4, a rotating motor 5 for driving the rotating shaft 4 to rotate is installed on one of the bearing plates 2, a placing plate 6 is provided at one end of the base 3, a stepping motor 7 for driving the placing plate 6 to rotate is installed at the other end of the base 3, a limiting assembly is provided on the placing plate 6, a lifting plate 8 and a lifting mechanism for driving the lifting plate 8 to lift and lower are also provided on the workbench 1, a hydraulic punching machine 9 is installed on the lifting plate 8, a displacement sensor 10 is installed on the piston rod of the hydraulic punching machine 9, and a PLC controller is provided on the workbench 1.

[0017] The limiting assembly includes a screw rod 11 fixedly connected to the placement plate 6, a nut 12 is threadedly connected to the screw rod 11, a fastening plate 13 is fixedly connected to the side of the nut 12 close to the placement plate 6, and the fastening plate 13 is slidably mounted on the screw rod 11.

[0018] Two slide rails 14 are provided on the workbench 1, and a slide seat 15 is slidably connected to the slide rails 14. The two bearing plates 2 are fixedly connected to the two slide seats 15 respectively. A first screw rod 16 and a first screw rod motor 17 that drives the first screw rod 16 to rotate are provided on the slide rail 14, and the slide seat 15 is threadedly connected to the first screw rod 16.

[0019] The lifting mechanism includes two mounting plates 18 vertically fixedly connected to the workbench 1, and a slide groove 19 is opened on the opposite side of the two mounting plates 18. A second screw rod 20 and a second screw motor 21 that drives the second screw rod 20 to rotate are arranged in one of the slide grooves 19. The lifting plate 8 is threadedly connected to the second screw rod 20, and a guide rod is fixedly connected in the other slide groove 19, and the lifting plate 8 is slidably sleeved on the guide rod.

[0020] Working principle:

[0021] During processing, the spoke workpiece is placed on the placement plate 6, sleeved on the screw 11, and the nut 12 is tightened to fix the spoke between the placement plate 6 and the fastening plate 13. The rotating motor 5 drives the base 3 to rotate 90° so that the spoke faces the hydraulic punching machine 9. The first screw motor 17 drives the first screw 16 to rotate, driving the spoke close to the hydraulic punching machine 9. The second screw motor 21 drives the second screw 20 to rotate, driving the lifting plate 9 to rise and fall, thereby adjusting the height of the hydraulic punching machine 9, so that the hydraulic punching machine 9 can punch holes on the surface of the hub, and thus can be applicable to more types of hub punching. The range is wider; during the processing, the PLC controller will rotate the output shaft of the stepper motor 7, and after the output shaft of the stepper motor 7 rotates to a predetermined angle, the output shaft of the stepper motor 7 will stop rotating, and the hydraulic punching machine 9 will punch holes on the surface of the spoke, and the displacement sensor 10 will record the moving distance of the punch of the hydraulic punching machine 9. When the punch reaches the preset punching depth, it can be considered that the punching is completed, and the displacement sensor 10 transmits the signal to the PLC controller, and the PLC controller will start the stepper motor 7 again to make the stepper motor 7 drive the placement plate 6 to rotate, and intermittently punch holes on the wheel hub.
