Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub detection, in particular to a wheel hub detection device for a skateboard. Background Art

[0002] Scooters are a simple means of transportation. They are popular among the public because of their moderate speed and easy operation. Adult scooters are usually designed with a maximum load of more than 80kg. Because they need to bear a large weight, the spokes and rims of the scooter wheel hub are usually made of metal materials or alloys such as aluminum alloy and stainless steel.

[0003] After the scooter wheel hub is produced, the roundness of the scooter wheel hub needs to be tested. Generally, the roundness of the scooter wheel hub is tested by manual testing. This testing method has certain human errors and low detection accuracy, which leads to an increase in the roundness deviation of the wheel hub obtained by the test, affecting the accuracy of the test. Utility Model Content

[0004] The purpose of the utility model is to design a wheel hub detection device for a skateboard, so as to solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A wheel hub detection device for a skateboard comprises a detection platform, a controller and a display light. A rotating motor is installed inside the detection platform, a turntable is provided above the detection platform, an output end of the rotating motor passes through the table surface of the detection platform and is fixedly connected to the turntable, a wheel hub to be detected is placed on the top of the turntable, a fixing mechanism for fixing the wheel hub is installed on the turntable, a plurality of micrometers aligned with the wheel hub are distributed around the circumference of the top of the detection platform, and the display light and the micrometer are both electrically connected to the controller.

[0007] Furthermore, the fixing mechanism includes a positioning column, a pressure plate and a nut, one end of the positioning column is fixed to the top of the turntable, the other end of the positioning column passes through the center hole of the wheel hub and is provided with an external thread, the pressure plate is provided with a through hole for the positioning column to pass through, the wheel hub is clamped between the turntable and the pressure plate, the nut is threadedly connected to the external thread, and the bottom of the nut is in contact with the top of the pressure plate.

[0008] Furthermore, a first rubber anti-skid pad is provided on the top of the turntable, and a second rubber anti-skid pad is provided on the bottom of the pressure plate.

[0009] Furthermore, the micrometers are provided with three.

[0010] Furthermore, a slider is fixedly connected to the bottom of the micrometer, and a sliding groove slidably connected to the slider is installed on the top of the detection platform.

[0011] Furthermore, the sliding groove includes a bottom plate fixed on the top of the detection platform, and positioning plates are fixedly connected to the opposite sides of the bottom plate.

[0012] Furthermore, one of the positioning plates is provided with a threaded hole, the threaded hole is threadedly connected with the bolt, and one end of the bolt passes through the threaded hole and presses the sliding block.

[0013] The beneficial effects of the utility model are:

[0014] The wheel hub is fixed on the turntable, and then the rotating motor is started to drive the turntable to rotate slowly, thereby driving the wheel hub to rotate. The roundness of the wheel hub is detected by the value change of the micrometer. When the value changes of several micrometers are less than the value set by the controller, the display light is on, and the roundness deviation of the wheel hub meets the requirements, eliminating human errors, with high detection accuracy, avoiding the increase of the detected wheel hub roundness deviation, and improving the accuracy of detection;

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-3 As shown, a wheel hub detection device for a skateboard includes a detection platform 1, a controller 2 and a display light 3. A rotating motor 4 is installed inside the detection platform 1. A turntable 5 is arranged above the detection platform 1. The output end of the rotating motor 4 passes through the table surface of the detection platform 1 and is fixedly connected to the turntable 5. A wheel hub 6 to be detected is placed on the top of the turntable 5. A fixing mechanism for fixing the wheel hub 6 is installed on the turntable 5. Three micrometers 7 aligned with the wheel hub 6 are distributed on the circumference of the top of the detection platform 1. The display light 3 and the micrometer 7 are both electrically connected to the controller 2. The rotating motor 4 is started to drive the turntable 5 to rotate slowly. This drives the wheel hub 6 to rotate, and the roundness of the wheel hub 6 is detected by the value change of the micrometer 7. The micrometer 7 transmits the sensed value change to the controller 2 through a signal. When the value changes of the three micrometers 7 are all less than the values ​​set by the controller 2, the controller 2 controls the display light 3 to light up, and the roundness deviation of the wheel hub 6 meets the requirements. Otherwise, the display light 3 is not on, and the roundness deviation of the wheel hub 6 does not meet the requirements and needs to be reprocessed. Human errors are eliminated, and the detection accuracy is high. The increase of the detected wheel hub roundness deviation is avoided, and the detection accuracy is improved. Since the wheel hub 6 is detected during the rotation process, the micrometer 7 may fail to detect the wheel hub 6, which will cause the value change of the micrometer 7 to be too small. By setting three micrometers 7 to detect the wheel hub 6, the probability of failing to detect the wheel hub 6 is reduced;

[0024] The fixing mechanism includes a positioning column 8, a pressure plate 9 and a nut 10. One end of the positioning column 8 is fixed to the top of the turntable 5. The other end of the positioning column 8 passes through the center hole of the wheel hub 6 and is provided with an external thread 11. The pressure plate 9 is provided with a through hole 12 for the positioning column 8 to pass through. The wheel hub 6 is clamped between the turntable 5 and the pressure plate 9. The nut 10 is threadedly connected with the external thread 11. The bottom of the nut 10 contacts the top of the pressure plate 9. A first rubber anti-skid pad 13 is provided on the top of the turntable 5, and a second rubber anti-skid pad 14 is provided on the bottom of the pressure plate 9. By tightening the nut 10, the pressure plate 9 presses the wheel hub 6 onto the turntable 5. The first rubber anti-skid pad 13 and the second rubber anti-skid pad 14 can increase friction and buffer to avoid crushing the wheel hub 6 and the wheel hub 6 rotating during rotation.

[0025] A slider 15 is fixedly connected to the bottom of the micrometer 7, and a base plate 16 is fixedly connected to the top of the inspection table 1. Positioning plates 17 are fixedly connected to the opposite sides of the base plate 16. The bottom of the slider 15 contacts the top of the base plate 16, and the slider 15 slides between the two positioning plates 17. A threaded hole 18 is provided on one of the positioning plates 17, and a bolt 19 is threadedly connected to the threaded hole 18. One end of the bolt 19 passes through the threaded hole 18 and presses the slider 15. The slider 15 can be pushed to slide between the two positioning plates 17 according to the outer diameter of the wheel hub 6. The distance between the sensing end of the micrometer 7 and the wheel hub 6 is adjusted so that the sensing end of the micrometer 7 enters the range where the wheel hub 6 can be sensed. By tightening the bolt 19, the slider 15 is pressed to prevent the jitter generated by the rotating motor 4 during operation from causing the slider 15 to move, thereby affecting the detection accuracy.

[0026] Working principle:

[0027] like Figure 1-3 As shown, when the detection device is used, the wheel hub 6 to be detected is first placed on the turntable 5 through the positioning column 8, and then the pressure plate 9 is placed on the wheel hub 6 through the positioning column 8, and then the nut 10 is tightened so that the pressure plate 9 presses the wheel hub 6 on the turntable 5, and the first rubber anti-skid pad 13 and the second rubber anti-skid pad 14 can play a role in increasing friction and buffering;

[0028] Then, according to the outer diameter of the wheel hub 6, the slider 15 is pushed to slide between the two positioning plates 17, and the distance between the sensing end of the dial gauge 7 and the wheel hub 6 is adjusted so that the sensing end of the dial gauge 7 enters the range where the wheel hub 6 can be sensed, and the slider 15 is compressed by tightening the bolt 19;

[0029] Finally, the controller 2 controls the rotation motor 4 to start, and the rotation motor 4 drives the turntable 5 to rotate slowly, thereby driving the wheel hub 6 to rotate, and the roundness of the wheel hub 6 is detected by the value change of the micrometer 7. The micrometer 7 will transmit the sensed value change to the controller 2 through a signal. When the value changes of the three micrometers 7 are all less than the values ​​set by the controller 2, the controller 2 controls the display light 3 to light up, and the roundness deviation of the wheel hub 6 meets the requirements. Otherwise, the display light 3 is not on, and the roundness deviation of the wheel hub 6 does not meet the requirements. Human errors are eliminated, the detection accuracy is high, and the increase of the detected wheel hub roundness deviation is avoided, thereby improving the accuracy of detection. Since the wheel hub 6 is detected during the rotation process, the micrometer 7 may fail to detect the wheel hub 6, resulting in too small a value change of the micrometer 7. By setting three micrometers 7 to detect the wheel hub 6, the probability of failing to detect the wheel hub 6 is reduced.

However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
