Description

Technical Field

[0001] The invention relates to the technical field of tire rim detection, and in particular to a tire rim thickness detection device and a correction method. Background Art

[0002] The tire rim is also called the wheel hub. It is a barrel-shaped metal component that supports the tire with its inner profile and is mounted on an axle in the center. Whether the wheel hub is damaged or deformed will directly affect our driving safety. At present, there are two main ways to detect the thickness of the tire rim. One is direct observation with the naked eye, and the other is to fix the tire with a fixture and then detect it with a handheld tester.

[0003] However, although the handheld detector is more accurate and convenient than direct observation with the naked eye, the staff needs to use the handheld detector to detect each tire rim. As the number of tire rims to be detected increases, the staff will feel muscle fatigue after holding the detector for a long time. At this time, it is easy for the staff to use the handheld detector to offset the detection position of the tire rim, resulting in a decrease in the accuracy of the detection data. In addition, the detection of the tire rim thickness requires the detection of multiple parts. When the staff use the handheld detector to detect multiple parts on the tire rim one by one, it will increase the staff's workload and lead to a decrease in the efficiency of tire rim thickness detection.

[0010] Optionally, the rotating assembly is composed of a driving gear and a turntable, and the outer wall of the driving gear is meshed with the inner wall of the turntable.

[0013] A tire rim thickness detection device and correction method, comprising the following operating steps:

[0014] S1. The staff puts the steel ring body on the outside of the left and right clamps and turns on the power of the No. 1 drive motor. After the No. 1 drive motor is turned on, it drives the rotation of the spur gear through the connection of the rotating shaft. Since the front and rear sides of the spur gear are respectively meshed with the teeth of the No. 1 ruler bar and the No. 2 ruler bar, the spur gear rotates in a circular direction while driving the horizontal movement of the No. 1 ruler bar and the No. 2 ruler bar. The movement of the left and right clamps will drive the movement of the clamps until the outer side of the clamps is against the inner wall of the steel ring body. When the staff loosens the steel ring body and the steel ring body is fixed on the outer side of the clamp, the power of the No. 1 drive motor can be turned off. At this time, the clamp can reinforce the steel ring body during inspection.

[0015] S2. Turn on the power of the No. 2 drive motor. After the No. 2 drive motor is turned on, it drives the rotation of the ball screw. Due to the connection method of the ball screw and the ball nut threaded sleeve, the ball screw rotates in a circular motion and drives the vertical lifting and lowering movement of the ball nut. While the ball nut moves, it drives the lifting and lowering movement of the extension rod inside the fixed rod through the connection of the short rod. While the extension rod moves, the roller rolls on the inner wall of the fixed rod to reinforce the stability of the extension rod's telescopic movement. The movement of the extension rod also drives the vertical movement of the steel ring body through the connection of the mounting plate. Until the steel ring body is moved to the detection area, the power of the No. 2 drive motor can be turned off. At this time, the No. 1 detector is aligned with the upper end face of the steel ring body, the No. 2 detector is aligned with the upper edge of the steel ring body, the No. 3 detector is aligned with the lower edge of the steel ring body, and the No. 4 detector is aligned with the lower end face of the steel ring body, so that the position correction during the thickness detection of the steel ring body can be completed.

[0016] S3, turn on the power of the No. 3 driving motor. After the No. 3 driving motor is turned on, the driving gear is driven to rotate through the connection of the annular ring. Since the driving gear is connected to the outer wall of the annular ring through the roller, the annular ring does not rotate while the driving gear rotates. At this time, the position of the steel ring body remains fixed, and the connection method of the driving gear and the turntable teeth meshing makes the turntable rotate while the driving gear rotates. When the turntable rotates, the detection component is driven to rotate outside the steel ring body through the connection of the vertical rod. When the detection component is reset after rotating one circle outside the steel ring body, the thickness of the steel ring body can be detected.

[0017] The present invention has the following beneficial effects:

[0018] 1. The tire rim thickness detection device and correction method realize the movement of the detection component through the coordination among the rim body, the clamping plate, the rotating component and the detection component, and utilize the setting of the rotating component, thereby effectively solving the problem of low efficiency in the thickness detection of the rim body. The rotating component drives the detection component to rotate outside the rim body, so that the detection component can simultaneously perform unified detection on multiple positions of the rim body, which not only reduces the workload of the staff, but also improves the efficiency of the rim body thickness detection.

[0019] 2. The tire rim thickness detection device and correction method realizes the movement of the clamping plates on both sides through the coordination among the rim body, the clamping plate, the adjustment component and the detection component, and utilizes the setting of the adjustment component, thereby effectively solving the problem of different inner diameters of the rim body. The adjustment component is used to drive the clamping plate to move inside the rim body, so that the clamping plate can be adjusted according to the inner diameter of the rim body, thereby expanding the applicable range of the clamping plate and improving the practicality of the clamping plate.

[0020] 3. The tire steel rim thickness detection device and correction method realizes the lifting and lowering movement of the steel rim body through the coordination among the steel rim body, the clamping plate, the lifting assembly and the detection assembly, utilizing the setting of the lifting assembly, effectively solving the problem of height adjustment during steel rim body detection, and adopts the method of using the lifting assembly to drive the steel rim body to move on one side of the detection assembly, so that the steel rim body is moved to the area that needs to be detected by the detection assembly, thereby improving the accuracy of the detection assembly in detecting the position of the steel rim body.

The back of the No. 1 ruler bar 302 is meshed with the front teeth of the spur gear 301, and the front of the No. 2 ruler bar 303 is meshed with the back teeth of the spur gear 301. The tooth meshing connection mode allows the spur gear 301 to rotate in a circle while driving the No. 1 ruler bar 302 and the No. 2 ruler bar 303 to move horizontally. The outer end of the No. 1 ruler bar 302 is fixedly connected to the inner wall of the left clamping plate 2, and the outer end of the No. 2 ruler bar 303 is fixedly connected to the inner wall of the right clamping plate 2.

The outer wall of the driving gear 901 is meshed with the inner wall of the turntable 902. The tooth meshing connection mode enables the rotation of the driving gear 901 to drive the rotation of the turntable 902, thereby realizing the rotation detection of the detection component 10 outside the steel ring body 1.

[0038] The inner wall of the driving gear 901 is rotatably connected to the outer wall of the annular ring 17 through a ball bearing. The ball bearing connection method makes it possible for the driving gear 901 to rotate without driving the steel ring body 1, thereby facilitating the detection of the thickness of the steel ring body 1. A bracket 18 is fixedly installed on the lower end surface of the driving gear 901. The installation of the bracket 18 serves to connect the driving gear 901 with the No. 3 drive motor 19.

Magnetron detectors, optically controlled detectors, or handheld detectors are all existing mature instruments for detecting tire rims, so they are not described here in detail.

[0040] A tire rim thickness detection device and correction method, comprising the following operating steps:

[0041] S1. The staff puts the steel ring body 1 on the outside of the clamping plates 2 on the left and right sides, and turns on the power of the No. 1 driving motor 13. After the No. 1 driving motor 13 is turned on, it drives the rotation of the spur gear 301 through the connection of the rotating shaft 12. Since the front and rear sides of the spur gear 301 are respectively meshed with the teeth of the No. 1 ruler bar 302 and the No. 2 ruler bar 303, the spur gear 301 rotates in a circular direction while driving the horizontal movement of the No. 1 ruler bar 302 and the No. 2 ruler bar 303. The movement of the No. 1 ruler bar 302 and the No. 2 ruler bar 303 will drive the movement of the clamping plates 2 on the left and right sides until the outer side of the clamping plate 2 is against the inner wall of the steel ring body 1. When the staff loosens the steel ring body 1 and the steel ring body 1 is fixed on the outer side of the clamping plate 2, the power of the No. 1 driving motor 13 can be turned off. At this time, the clamping plate 2 can reinforce the steel ring body 1 during inspection.

[0042] S2, turn on the power of the second drive motor 16. After the second drive motor 16 is turned on, it drives the rotation of the ball screw 701. Due to the threaded connection between the ball screw 701 and the ball nut 702, the ball screw 701 rotates in a circular manner and drives the vertical lifting movement of the ball nut 702. When the ball nut 702 moves, the extension rod 5 is driven to move up and down inside the fixed rod 6 through the connection of the short rod 703. When the extension rod 5 moves, the roller 8 rolls on the inner wall of the fixed rod 6 to reinforce the extension rod 5. To ensure the stability of the contraction movement, the movement of the extension rod 5 drives the vertical movement of the steel ring body 1 through the connection of the mounting plate 4, until the steel ring body 1 is moved to the detection area, and the power supply of the No. 2 driving motor 16 can be turned off. At this time, the No. 1 detector 101 is aligned with the upper end face of the steel ring body 1, the No. 2 detector 102 is aligned with the upper edge of the steel ring body 1, the No. 3 detector 103 is aligned with the lower edge of the steel ring body 1, and the No. 4 detector 104 is aligned with the lower end face of the steel ring body 1, so as to complete the position correction of the steel ring body 1 during the thickness detection.

[0043] S3, turn on the power supply of the No. 3 driving motor 19. After the No. 3 driving motor 19 is turned on, the driving gear 901 is driven to rotate through the connection with the annular ring 17. Since the driving gear 901 is connected to the outer wall of the annular ring 17 through a roller, the annular ring 17 does not rotate while the driving gear 901 rotates. At this time, the position of the steel ring body 1 remains fixed, and the connection mode of the tooth meshing between the driving gear 901 and the turntable 902 makes the turntable 902 rotate while the driving gear 901 rotates. When the turntable 902 rotates, the detection component 10 is driven to rotate outside the steel ring body 1 through the connection with the vertical rod 22. When the detection component 10 is reset after rotating one circle outside the steel ring body 1, the thickness of the steel ring body 1 can be detected.

Since the front and rear sides of the spur gear (301) are respectively meshed with the teeth of the No. 1 ruler bar (302) and the No. 2 ruler bar (303), the spur gear (301) rotates in a circle and drives the No. 1 ruler bar (302) and the No. 2 ruler bar (303). The horizontal movement of the ruler bar (303) and the movement of the No. 1 ruler bar (302) and the No. 2 ruler bar (303) will drive the movement of the clamping plates (2) on the left and right sides until the outer side of the clamping plates (2) abuts against the inner wall of the steel ring body (1). When the staff releases the steel ring body (1) and the steel ring body (1) is fixed on the outer side of the clamping plates (2), the power supply of the No. 1 driving motor (13) can be turned off. At this time, the clamping plates (2) can reinforce the steel ring body (1) during inspection. S2, turning on the power supply of the second drive motor (16), after which the second drive motor (16) is turned on, drives the ball screw (701) to rotate. Due to the threaded connection between the ball screw (701) and the ball nut (702), the ball screw (701) rotates in a circular motion and drives the ball nut (702) to move vertically. When the ball nut (702) moves, it drives the extension rod (5) to move upward and downward inside the fixed rod (6) through the connection with the short rod (703). When the extension rod (5) moves, the roller (8) rolls on the inner wall of the fixed rod (6), thereby reinforcing the extension rod (5). To ensure the stability of the telescopic movement, the movement of the extension rod (5) drives the vertical movement of the steel ring body (1) through the connection with the mounting plate (4) until the steel ring body (1) is moved to the detection area and the power supply of the second drive motor (16) is turned off. At this time, the first detector (101) is aligned with the upper end face of the steel ring body (1), the second detector (102) is aligned with the upper edge of the steel ring body (1), the third detector (103) is aligned with the lower edge of the steel ring body (1), and the fourth detector (104) is aligned with the lower end face of the steel ring body (1), so that the position correction of the steel ring body (1) during the thickness detection can be completed. S3, turning on the power supply of the third driving motor (19). After the third driving motor (19) is turned on, the driving gear (901) is driven to rotate through the connection of the annular ring (17). Since the driving gear (901) is connected to the outer wall of the annular ring (17) through a roller, the annular ring (17) does not rotate while the driving gear (901) rotates. At this time, the position of the steel ring body (1) remains fixed, and the toothed connection mode of the driving gear (901) and the rotating disk (902) is engaged, so that the rotating disk (902) rotates while the driving gear (901) rotates. When the rotating disk (902) rotates, the detection component (10) is driven to rotate outside the steel ring body (1) through the connection of the vertical rod (22). When the detection component (10) rotates one circle outside the steel ring body (1) and resets, the thickness of the steel ring body (1) can be detected.
