[0036] Example 1

[0037] This embodiment provides a wheel hub insert screw automatic locking device, which realizes automatic screw locking processing of the wheel hub insert. During this process, no manual operation is required, which improves the screw locking efficiency of the wheel hub insert and effectively reduces the labor intensity of the operator. In addition, it can accurately control the locking depth and pre-tightening force of the screw, thereby improving the locking effect of the wheel hub insert.

[0038] Combine Figures 1 to 6As shown, the wheel hub plug-in screw automatic locking device of this embodiment needs to lock the plug-in on the wheel hub. The wheel hub plug-in screw automatic locking device includes a conveying line body 10, a clamping jaw part 20 and a locking part 30. The conveying line body 10 conveys the wheel hub to be locked, the clamping jaw part 20 clamps the wheel hub and moves it to the locking position, and the locking part 30 locks the wheel hub. After the locking is completed, the wheel hub is moved back to the conveying line body 10 and the wheel hub can be sent out.

[0039] In this embodiment, the wheel hub plug-in screw automatic locking device also includes a frame 80, the conveyor line body 10, the clamping claw part 20 and the locking part 30 are all located in the frame 80, and a height measuring light curtain 90 is provided at the end of the frame 80. The height measuring light curtain 90 is located at the inlet end of the conveyor line body 10 to measure the height of the wheel hub before entering the conveyor line body 10. The wheel hub plug-in screw automatic locking device of this embodiment is suitable for wheels of different specifications. Therefore, the height measuring light curtain 90 is used at the end of the frame 80 to measure the height of the wheel hub to determine the specifications of the wheel hub.

[0040] Combine Figure 1 and Figure 6 As shown, the front end of the conveyor line body 10 of this embodiment is provided with a positioning part 40, and the positioning part 40 includes a lifting and rotating mechanism 41 and a lifting and positioning camera 42. The lifting and rotating mechanism 41 is installed below the conveyor line body 10, and the lifting and positioning camera 42 is located above the lifting and rotating mechanism 41 to position the wheel hub. The wheel hub moves to the position of the lifting and rotating mechanism 41 under the action of the conveyor line body 10. After the wheel hub is lifted by the lifting and rotating mechanism 41, the lifting and positioning camera 42 located above the lifting and rotating mechanism 41 can perform visual inspection on the wheel hub, and the rotating structure 413 is used to adjust the orientation of the wheel hub according to the visual inspection result so as to facilitate the subsequent locking operation of the wheel hub.

[0041] In this embodiment, the lifting and rotating mechanism 41 includes a mounting plate 411, a lifting cylinder 412 and a rotating structure 413. The lifting cylinder 412 is fixed on the mounting plate 411. The rotating structure 413 includes a fixed plate 4131, a rotating drive motor 4132, a rotating connector 4133 and a rotating support 4134. The fixed plate 4131 is installed on the piston rod end of the lifting cylinder 412. The rotating drive motor 4132 is installed on the fixed plate 4131 and drives the rotating connector 4133 to rotate. The rotating support 4134 34 is connected to the rotating connection 4133. When the wheel hub is positioned, the jacking cylinder 412 pushes out the rotating structure 413, so that the wheel hub falls on the surface of the rotating support 4134 of the rotating structure 413. At this time, the jacking operation of the wheel hub is completed, and the rotating structure 413 drives the rotating support 4134 through the rotating connection 4133 by the rotating drive motor 4132 according to the visual detection result of the jacking positioning camera 42, so that the wheel hub is rotated and the relative position of the wheel hub is changed so as to facilitate the subsequent locking operation of the wheel hub.

[0042] Specifically, the rotating support member 4134 of this embodiment is a cross-shaped structure, the conveyor line body 10 is a roller conveyor line, and the rotating support member 4134 is located in the gap space of the conveyor line body 10. Therefore, the rotating support member 4134 can be staggered with the conveyor line body 10, while ensuring support for the hub, avoiding interference with the conveyor line body 10, and effectively positioning the hub during transportation.

[0043] Combine Figure 1 、 Figure 3 as well as Figure 4 As shown, the clamping claw portion 20 of this embodiment is located above the conveying line body 10, and the clamping claw portion 20 includes a bracket 21, a clamping cylinder 22 and a pressure plate 23. The clamping cylinder 22 and the pressure plate 23 are both connected to the bracket 21. The clamping cylinder 22 is provided with two groups of clamping arms 221 to clamp the hub. The pressure plate 23 is provided with a plurality of elastic pressing members 231 to press the plug-in on the hub. A transfer portion 50 is provided on the side of the conveying line body 10. The transfer portion 50 includes a first module 51, a second module 52 and a rotating module 53. The second module 52 moves along the length direction of the first module 51, and the rotating module 53 moves along the length direction of the second module 52. The bracket 21 is installed on the rotating module 53. After the hub positioning is completed Under the action of the first module 51 and the second module 52 of the transfer part 50, the clamping claw part 20 is moved above the wheel hub, and then the clamping cylinder 22 of the clamping claw part 20 is started, the clamping arm 221 clamps the wheel hub, and the elastic pressure piece 231 on the pressure plate 23 presses the plug-in on the wheel hub. The elastic pressure piece 231 is equivalent to manual pressure during manual operation, so that the wheel hub can be locked subsequently. After the clamping claw part 20 clamps the wheel hub, the rotating module 53 rotates the clamping claw part 20 so that the wheel hub corresponds to the locking part 30. The first module 51 and the second module 52 of this embodiment are both linear modules, and the rotating module 53 is driven by a rotary motor to rotate the clamping claw part 20 as a whole.

[0044] In this embodiment, the inner ring of the clamping arm 221 is an arc-shaped concave structure, and a plurality of clamping wheels 2211 are provided on the clamping arm 221. There is a protrusion on the edge of the clamping wheel 2211. Therefore, the clamping arm 221 can stably clamp the wheel hub through the clamping wheel 2211 while also effectively supporting the wheel hub to ensure the stability of subsequent locking operations. The elastic pressure piece 231 includes a fixed rod 2311 and an elastic pressure head 2312. The elastic pressure head 2312 is connected to the fixed rod 2311 through a spring 60. The elastic pressure head 2312 contacts the plug-in on the wheel hub, so the elastic pressure head 2312 realizes flexible pressing of the plug-in (equivalent to manual pressing operation during manual operation). While protecting the plug-in, it can also improve the locking accuracy of the wheel hub and avoid the problem of locking deviation.

[0045] Combine Figure 1 and Figure 5 As shown, the locking part 30 of this embodiment includes a locking module 31 and a locking head 32. The locking module 31 drives the locking head 32 to approach the locking position for locking. The locking head 32 is connected to the locking module 31 through a locking bracket 7021. The locking bracket 7021 is provided with a locking positioning camera 71. Before the locking part 30 locks the wheel hub, the locking positioning camera 71 visually locates the wheel hub again. According to the visual positioning result, the locking module 31 drives the locking head 32 to move to a predetermined position, and then the locking head 32 locks the wheel hub to lock the plug-in to the wheel hub. The locking module 31 of this embodiment is a three-axis driving module, which adjusts the position of the locking head 32 along three directions. The locking head 32 is a locking electric screwdriver to perform screw locking.

[0046] In actual use of the automatic locking device for wheel hub plug-in screws of this embodiment, the wheel hub is conveyed through the conveyor line 10. When it reaches the positioning part 40, the wheel hub is lifted by the lifting and rotating mechanism 41 of the positioning part 40. According to the visual detection result of the lifting and positioning camera 42, the rotating structure 413 rotates the wheel hub to change the relative position of the wheel hub, which is beneficial to the subsequent locking process of the wheel hub. After the positioning of the wheel hub is completed, the transfer part 50 moves the clamping part 20 to the top of the wheel hub, and the clamping part 20 clamps the wheel hub and, with the cooperation of the transfer part 50, moves the wheel hub to the locking position. The locking module 31 of the locking part 30 drives the locking head 32 close to the wheel hub, thereby locking the wheel hub. After the locking is completed, the wheel hub is transferred back to the conveyor line 10 and sent out.

[0047] Example 2

[0048] like Figure 7 As shown, this embodiment provides a method for using a wheel hub insert screw automatic locking device, comprising the following steps:

[0049] S1. After the height is measured, the wheel hub enters the conveyor line 10, and the conveyor line 10 conveys the wheel hub to the positioning unit 40, which adjusts the position of the wheel hub so that the wheel hub presents the best locking orientation;

[0050] S2: The lifting and rotating mechanism 41 of the positioning unit 40 lifts the wheel hub, and the lifting and positioning camera 42 visually locates the wheel hub. The wheel hub is then rotated to a predetermined position. After the lifting and positioning camera 42 visually inspects the wheel hub, the rotating structure 413 of the lifting and rotating mechanism 41 rotates the wheel hub according to the visual inspection results and adjusts it to the locking position.

[0051] S3. The clamping jaw 20 moves to the hub position under the action of the transfer unit 50, grabs the hub, and uses the elastic pressure piece 231 to press the plug on the hub, moving the hub to the locking position. Under the transfer action of the transfer unit 50, the position of the clamping jaw 20 is changed. After the clamping jaw 20 clamps the hub, the transfer unit 50 moves the hub to the locking position for subsequent locking operations.

[0052] S4. The locking module 31 of the locking portion 30 drives the locking head 32 close to the wheel hub, and the locking head 32 locks the plug-in on the wheel hub. The locking head 32 of this embodiment is a locking electric screwdriver, which is used to install the screws into the wheel hub, thereby firmly locking the plug-in on the wheel hub.
