[0002] A wheel hub, also called a rim, is a cylindrical metal component that supports the tire and is centrally mounted on an axle. Wheel hubs require inspection during the production process to identify problems promptly. Because wheel hubs are transported between workshops during production, their outer circumference may be damaged by collisions. Therefore, it is necessary to inspect the circumference of the wheel hub to detect defective hubs. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1 - Appendix Figure 4 As shown, a wheel hub circumference inspection device includes a frame 1, a base 2 on the frame 1, a support seat 3 on the base 2, a support shaft 4 at the center of the upper part of the support seat 3, a lifting mechanism 5 on the frame 1, a lifting arm 6 driven by the lifting mechanism 5, a rotating seat 7 on the lifting arm 6, a rotating shaft 8 rotatably mounted inside the rotating seat 7, a handwheel 10 connected to the upper end of the rotating shaft 8, a rotating arm 9 connected to the lower end of the rotating shaft 8, a positioning shaft 11 connected to the lower part of the rotating arm 9, the positioning shaft 11 and the support shaft 4 being arranged vertically opposite each other, an installation frame 16 is installed at the end of the rotating arm 9 away from the positioning shaft 11, a positioning rod 17 is connected inside the installation frame 16, the positioning rod 17 is arranged along the length direction of the rotating arm 9, a slider 18 is slidably mounted on the positioning rod 17, a central shaft 19 is connected to the lower part of the slider 18, a roller 12 is rotatably mounted on the central shaft 19, and two springs 28 are mounted on the positioning rod 17, the two springs 28 being located on the left and right sides of the slider 18 respectively. The slider 18 is kept in balance by the springs 28 on both sides, and will move accordingly when subjected to external force.

[0021] The wheel hub is placed on support base 3, and support shaft 4 is inserted from the lower end of the wheel hub shaft hole. Support base 3 supports the hub's drum. The lifting mechanism lowers the lifting arm 6, allowing positioning shaft 11 to be inserted into the upper end of the wheel hub shaft hole. Positioning is achieved by inserting positioning shaft 11 into the shaft hole. The position of roller 12 is predetermined, allowing it to contact the outer circumference of the wheel hub. Handwheel 10 drives rotating shaft 8, which in turn drives rotating arm 9, which in turn drives roller 12. Roller 12 can move against the outer circumference of the wheel hub. When the outer circumference of the wheel hub has defects, such as protrusions or depressions, roller 12 will move outward or inward accordingly. Workers can determine whether there are problems with the wheel hub's circumference by observing the state of roller 12.

[0022] The rotating arm 9 has an installation groove 13, and the installation frame 16 is set in the installation groove 13. The installation groove 13 is connected to the left end of the lifting arm 6. The rotating arm 9 has an opening 14 and an opening 25 respectively located on the upper and lower sides of the installation groove 13. The opening 14 and the opening 25 are respectively connected to the installation groove 13. The upper part of the installation frame 16 is connected to a fixing screw 20, and a fixing bolt 22 is threaded onto the fixing screw 20.

[0023] The mounting frame 16 can move within the mounting groove 13, allowing adjustment of the distance between the roller 12 and the positioning shaft 11. The mounting frame 16 is secured by the cooperation of the fixing screw 20 and the fixing bolt 22. The position of the roller 12 is adjustable, making it suitable for inspecting hubs of different sizes.

[0024] A washer 21 is fitted on the fixing screw 20. The washer 21 is located below the fixing bolt 22. The washer 21 can increase the contact area to enhance the fixing effect.

[0025] As attached Figure 3 As shown, the mounting frame 16 includes two end plates 23, with two side plates 24 connected between them. A positioning rod 17 is located between the two end plates 23, with both ends of the positioning rod 17 connected to the inner surfaces of the two end plates 23 respectively. A scale 26 is provided on one of the side plates 24, extending along the length of the side plate 24. A pointer 27 is provided on the slider 18, with the end of the pointer 27 away from the slider 18 pointing towards the scale 26. A notch 29 is provided on the rotating arm 9, parallel to the opening 14, allowing the ends of the scale 26 and pointer 27 to protrude. Through the cooperation of the pointer 27 and the scale 26, the operator can more intuitively observe the movement of the roller 12, facilitating judgment.

[0026] As attached Figure 5 As shown, the lifting mechanism 5 includes a column 30, with a groove 31 on the side of the column 30. A lead screw 32 is rotatably mounted in the groove 31. A lead screw motor 33 is mounted on the upper part of the column 30, driving the lead screw 32. A lead screw slider 34 is mounted on the lead screw 32, and the lifting arm 6 is mounted on the lead screw slider 34. By driving the lead screw 32 to rotate forward and backward through the lead screw motor 33, the lead screw slider 34 is moved, thereby completing the lifting of the lifting arm 6.

[0027] As attached Figure 5 As shown, the device also includes a fixing pin 35, a through hole 36 on the lifting arm 6, and a fixing hole 37 on the rotating arm 9. The lower end of the fixing pin 35 can pass through the through hole 36 and be inserted into the fixing hole 37. At this time, the position of the rotating arm 9 is fixed and cannot rotate, which facilitates the operator to adjust the position of the roller 12.

[0028] The support base 3 is rotatably mounted on the base 2. A driven wheel 39 is connected to the outer periphery of the support base 3. A drive motor 40 is mounted on the frame 1, and the drive motor 40 drives a driving wheel 41. A transmission belt 25 connects the driving wheel 41 and the driven wheel 39. After the rotating arm 9 is fixed in position, the lifting mechanism 5 drives the lifting arm 6 to descend, causing the roller 12 to contact the outer periphery of the hub. At this time, the drive motor 40 drives the driving wheel 41 to rotate. The driving wheel 41 drives the support base 3 to rotate through the transmission belt 25 and the driven wheel 39, thereby driving the hub to rotate actively and completing the secondary inspection. By conducting two inspections, the number of incorrect or missed inspections can be reduced.

[0029] The device also includes a bushing 38, which can be fitted onto the positioning shaft 11 or the support shaft 4 to fill the gap between the positioning shaft 11, the support shaft 4 and the shaft hole, thereby achieving better positioning.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
