Description

Technical Field

[0001] This utility model relates to a tire measuring device, and more particularly to a measuring device capable of measuring the cross-sectional width of a tire. Background Technology

[0002] In current tire measurement methods, the section width of a tire is mostly measured manually, for example, using calipers. Manual measurement suffers from low efficiency and low accuracy.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0004] In view of the problems pointed out in the background art, this utility model proposes a tire measuring device to realize the automated measurement of the cross-sectional width of the tire, thereby improving measurement efficiency and accuracy.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0006] In some embodiments of this application, a tire measuring device is provided, comprising:

[0007] The workstation axis is configured to mount the tire to be tested;

[0008] The measuring module includes a lateral moving component and a longitudinal moving component. The lateral moving component is configured to drive the longitudinal moving component to move in a direction parallel to the workstation axis. The longitudinal moving component is configured to move in a direction closer to or farther from the workstation axis. A laser measuring device is provided at one end of the longitudinal moving component that is closer to the workstation axis.

[0009] The tire measuring device of this application can automatically measure the tire section width. When measuring the tire section width, the tire is mounted on a workstation shaft. The tire includes a first sidewall and a second sidewall. The longitudinal moving component is initially located on the side of the first sidewall, and the laser measuring device is also located on the side of the first sidewall. The lateral moving component drives the longitudinal moving component to move closer to the first sidewall, causing the laser measuring device to move closer to the first sidewall. When the laser contacts the highest point of the first sidewall, the longitudinal moving component stops moving, and the laser measuring device feeds back the detected data to the controller. Then, the lateral moving component drives the longitudinal moving component to move to the side of the second sidewall. The lateral moving component then drives the longitudinal moving component to move closer to the second sidewall, causing the laser measuring device to move closer to the second sidewall. When the laser contacts the highest point of the second sidewall, the longitudinal moving component stops moving, and the laser measuring device feeds back the detected data to the controller. The controller calculates the tire section width based on the feedback data from the laser measuring device.

[0010] By driving the longitudinal movement component through a lateral movement component, the laser measuring device switches positions on different sides of the tire and gradually moves closer to the tire sidewall, measuring the two maximum positions of the tire's section width to obtain the tire's section width. This tire measuring device can automatically detect the tire's section width, improving measurement efficiency and accuracy.

[0011] By using a longitudinal moving component to move the laser measuring device closer to or further away from the tire, the laser measuring device is always kept at the optimal measuring distance from the tire, which helps to improve measurement accuracy.

[0012] In some embodiments of this application, the lateral movement component includes a first support base, on which a first guide rail is disposed, and the longitudinal movement component is provided with a first slider, the first slider being slidably connected to the first guide rail;

[0013] The lateral movement component further includes a lateral drive unit configured to drive the longitudinal movement component to move along the first guide rail.

[0014] In some embodiments of this application, the lateral drive unit includes a first motor, the power output end of the first motor is connected to a first lead screw, a first nut is sleeved on the first lead screw, and the first nut is connected to the longitudinal movement component.

[0015] In some embodiments of this application, the longitudinal movement component includes a second support base, the first slider is disposed on the second support base, and the second support base is further provided with a second slider;

[0016] The longitudinal movement component further includes a longitudinal drive unit, on which a second guide rail is provided, the second slider is slidably connected to the second guide rail, and the laser measuring device is provided on the longitudinal drive unit.

[0017] In some embodiments of this application, the longitudinal drive unit includes a support frame, a second motor is mounted on the support frame, the power output end of the second motor is connected to a second lead screw, a second nut is sleeved on the second lead screw, the second nut is connected to the second support seat through a connecting seat, and the support frame is equipped with a second guide rail and the laser measuring device.

[0018] In some embodiments of this application, the second motor is disposed at one end of the support frame, the laser measuring device is disposed at the other opposite end of the support frame, and the second lead screw is disposed in the internal space of the support frame.

[0019] In some embodiments of this application, an encoder is provided on the workstation shaft.

[0020] The tire measuring device of this application can automatically measure the outer circumference of a tire. When measuring the outer circumference of a tire, the longitudinal moving component drives the lateral moving component to a position facing the tire tread, and the laser measuring device faces the tire tread; the station shaft drives the tire to rotate one revolution; the controller calculates the outer circumference of the tire based on the data fed back by the laser measuring device.

[0021] When measuring the outer circumference of a tire, the workstation shaft rotates the tire one revolution. A laser measuring device locates the maximum position of the tire's outer circle, and then the outer circumference is calculated. The tire outer circumference measurement process enables full-size tire measurement, improving measurement accuracy.

[0041] In some embodiments of this application, a tire measuring device is provided, with reference to... Figure 1 The tire measuring device includes a station shaft 10, which is configured to mount the tire 30 to be tested.

[0042] The tire measuring device also includes a measuring module 20. Figure 2 This is a structural diagram of the measurement module 20. Figure 3 A structural diagram of the measurement module 20 as viewed from the other side.

[0043] The measuring module 20 includes a lateral movement component 100 and a longitudinal movement component 200. The lateral movement component 100 is configured to drive the longitudinal movement component 200 to move in a direction parallel to the workstation axis 10. The longitudinal movement component 200 is configured to move toward or away from the workstation axis 10. A laser measuring device 300 is provided at the end of the longitudinal movement component 200 closest to the workstation axis 10.

[0044] The tire measuring device also includes a controller (not shown), and the laser measuring device 300 communicates with the controller.

[0045] The tire measuring device of this application can automatically measure the tire section width. When measuring the section width of the tire 30, the tire 30 is mounted on the workstation shaft 10. The tire 30 includes a first sidewall 31 and a second sidewall 32. The longitudinal moving component 200 is initially located on the side of the first sidewall 31, and the laser measuring device 300 is also located on the side of the first sidewall 31. The lateral moving component 100 drives the longitudinal moving component 200 to move towards the first sidewall 31, causing the laser measuring device 300 to move towards the first sidewall 31. When the laser contacts the highest point of the first sidewall 31, the longitudinal moving component 200 stops moving, and the laser measuring device 300... The detected data is fed back to the controller; then the lateral moving component 100 drives the longitudinal moving component 200 to move as a whole to the side of the second tire sidewall 32. The lateral moving component 100 then drives the longitudinal moving component 200 to move closer to the second tire sidewall 32, so that the laser measuring device 300 moves closer to the second tire sidewall 32. When the laser touches the highest point of the second tire sidewall 32, the longitudinal moving component 200 stops moving, and the laser measuring device 300 feeds back the detected data to the controller; the controller calculates the cross-sectional width of the tire 30 based on the feedback data from the laser measuring device 300.

[0046] By driving the longitudinal movement component 200 through the lateral movement component 100, the laser measuring device 300 is positioned on different sides of the tire 30, and its movement gradually approaches the tire sidewall, measuring the two maximum positions of the tire 30's cross-sectional width, thereby obtaining the tire 30's cross-sectional width. This tire measuring device can automatically detect the tire 30's cross-sectional width, improving measurement efficiency and accuracy.

[0047] The longitudinal moving component 200 drives the laser measuring device 300 to move closer to or further away from the tire 30, so that the laser measuring device 300 always maintains the optimal measuring distance from the tire 30, which helps to improve the measurement accuracy.

[0048] In some embodiments of this application, an encoder 400 is provided on the workstation shaft 10.

[0049] The tire measuring device of this application can automatically measure the outer perimeter of the tire. When the outer perimeter of the tire 30 is measured, the longitudinal moving component 200 drives the lateral moving component 100 to move to a position facing the tread 33 of the tire 30, and the laser measuring device 300 faces the tread 33 of the tire 30; the station shaft 10 drives the tire 30 to rotate one revolution; the controller calculates the outer perimeter of the tire 30 based on the data fed back by the laser measuring device 300.

[0050] When measuring the outer perimeter of tire 30, the station shaft 10 rotates tire 30 one revolution. The laser measuring device 300 locates the maximum position of the outer circle of tire 30, and then calculates the outer perimeter of tire 30. The tire 30 outer perimeter measurement process can achieve full-size coverage measurement of tire 30, improving measurement accuracy.
