Technical Field

[0001] The utility model relates to the technical field of tire detection, and more specifically to a vehicle tire detection device. Background Art

[0002] Tire testing refers to testing various performance data of tires to ensure the quality of the tires. Common testing items include tire tread depth testing. When performing this test, the staff will use a tire testing device equipped with a laser scanner to obtain tread data by clamping the tire on a rotating placement table and performing a comprehensive laser scan of the tire.

[0003] However, the existing placement table only pushes against the inner edge of the tire through a number of push rods when clamping the tire. The thickness of the inner edge of the tire is relatively low, which leads to a limited contact area between the inner edge of the tire and the push rods. When rotating at high speed, the friction between the tire and the push rods may be insufficient, causing the tire to shake or even fall off, affecting the detection results. Therefore, it is urgent to design an automobile tire detection device to solve the above problems. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a vehicle tire detection device to solve the problem in the above background technology that the friction between the tire and the push rod may be insufficient, resulting in the tire shaking or even falling off.

[0006] The mounting assembly includes an L-shaped rod, which is slidably mounted on the top of the placement assembly. A first circular groove is provided on the outer side of the L-shaped rod. The second contact assembly includes a contact rod and an ejection spring. The contact rod is slidably mounted in the first circular groove. A third circular groove is provided in the contact rod. The ejection spring is fixedly mounted between the inner walls of the first circular groove and the third circular groove.

[0007] Furthermore, the power assembly includes a rotating disk, four connecting plates, and a driving motor. The rotating disk is rotatably installed on the top of the workbench through the motor. The four connecting plates and the driving motor are fixedly installed on the top of the rotating disk. The placement assembly includes a placement disk, which is fixedly installed between the tops of the four connecting plates.

[0008] Furthermore, the placement assembly also includes four sliders and a transmission plate. The top of the placement plate is provided with four first strip grooves, and the four sliders are slidably installed in the four first strip grooves respectively. The transmission plate is rotatably installed at the bottom of the placement plate. The bottom of the transmission plate is provided with four second strip grooves. The transmission plate is rotatably sleeved between the outer walls of the four sliders through the four second strip grooves. The L-shaped rod is fixedly installed on the top of the slider, and the transmission plate is fixedly connected to one end of the output shaft of the drive motor.

[0009] Furthermore, the first contact assembly includes a contact block, two limit springs, a cross bar, and a fixed rod. A vertical groove is provided on the outer side of the L-shaped rod, and the contact block is slidably installed in the vertical groove.

[0011] Furthermore, an inserting hole is formed on the outer wall of the contact rod, and the inserting rod is slidably inserted into the inserting hole.

[0012] Furthermore, a plurality of semicircular protrusions are arranged on the top of the placement plate.

[0013] Technical effects and advantages of the utility model:

[0014] When the utility model is in use, the tire is placed on the top of the placing plate, and the driving motor drives the transmission plate to rotate. When the transmission plate rotates, it pushes the four sliding blocks to slide away from each other in the four first strip grooves through the four second strip grooves, thereby driving the four L-shaped rods to move away from each other.

At this time, the contact block will be squeezed and enter the vertical groove, and the two limit springs will also be compressed into the two second circular grooves. At this time, the four L-shaped rods can push the inner opening of the tire through the four contact blocks. In the process of the contact block engaging with the vertical groove, it will push the cross bar and the fixed rod to slide. When the fixed rod slides, it will push the sliding plate to slide downward through the guide groove, thereby driving the insertion rod to slide downward. When the contact block slides to the end of the vertical groove, the insertion rod will just slide to disengage from the socket. At this time, the contact rod will be unlocked, and the push-out spring will release and push the contact rod out of the first circular groove. The contact rod will contact the inner wall of the tire during the sliding process, and push the inner wall of the tire through the thrust of the push-out spring. At this time, start the laser scanner to start the detection. The motor at the bottom of the workbench drives the rotating disk to rotate, which can drive the tire to rotate. At this time, start the first contact assembly and the second contact assembly that are set, and the four contact blocks and the four contact rods will push the inner opening and inner wall of the tire at the same time. Compared with the prior art that only pushes the inner opening of the tire, the stability of the push is improved to a certain extent, and the tire is prevented from shaking during the detection process.

[0025] Figures 1 to 8 It is the best embodiment of the utility model, and the following Figures 1 to 8 The utility model is further described.

[0026] A vehicle tire testing device comprises a workbench 1, a power assembly 2, a placement assembly 3, four mounting assemblies 4, four first contact assemblies 5, four transmission assemblies 6, and four second contact assemblies 7, wherein the power assembly 2 is rotatably mounted on the top of the workbench 1 by a motor, the placement assembly 3 is fixedly mounted on the top of the power assembly 2, a tire can be placed on the top of the placement assembly 3, the mounting assembly 4 is slidably mounted on the top of the placement assembly 3, and the first contact assembly 5, the transmission assembly 6, and the second contact assembly 7 are all arranged in the mounting assembly 4;

[0027] The mounting assembly 4 includes an L-shaped rod 401, which is slidably mounted on the top of the placement assembly 3.

The L-shaped rod 401 is fixedly installed on the top of the slider 303, and the transmission disk 304 is fixedly connected to one end of the output shaft of the drive motor 203.

[0030] In this embodiment, the driving motor 203 drives the transmission disk 304 to rotate. When the transmission disk 304 rotates, it pushes the four sliders 303 to slide away from each other in the four first strip grooves 302 through the four second strip grooves 305, thereby driving the four L-shaped rods 401 to move away from each other.

[0031] Specifically, the first contact component 5 includes a contact block 501, two limit springs 502, a cross bar 503, and a fixed rod 505. A vertical groove 403 is provided on the outer side of the L-shaped rod 401, and the contact block 501 is slidably installed in the vertical groove 403. Two second circular grooves 404 are provided on the inner wall of the vertical groove 403. The two limit springs 502 are respectively fixedly installed in the two second circular grooves 404, and the two limit springs 502 are both fixedly connected to the contact block 501. A cross groove 405 is provided on the inner wall of the vertical groove 403. The cross bar 503 is slidably inserted in the cross groove 405, and the cross bar 503 is fixedly connected to the contact block 501. An empty groove 504 is provided in the cross bar 503, and the fixed rod 505 is fixedly installed in the empty groove 504.

[0032] In this embodiment, the limit spring 502 can prevent the contact block 501 from engaging into the vertical groove 403 before contacting the inner opening of the tire.

[0033] Specifically, the transmission assembly 6 includes a sliding plate 601 and an insertion rod 603. The sliding plate 601 is slidably installed in the empty groove 504. A guide groove 602 is opened between the two ends of the sliding plate 601. The fixed rod 505 is slidably installed in the guide groove 602. The insertion rod 603 is fixedly installed on the top of the sliding plate 601. A through hole 406 is opened at the bottom of the L-shaped rod 401. The insertion rod 603 is slidably inserted in the through hole 406.

[0034] Specifically, an inserting hole 704 is formed on the outer wall of the contact rod 701 , and the inserting rod 603 is slidably inserted into the inserting hole 704 .

[0035] Specifically, a plurality of semicircular protrusions are provided on the top of the placement plate 301 .

[0036] In this embodiment, by providing the semicircular protrusions, when placing the tire, the tire will only contact the semicircular protrusions, resulting in less friction, making it easier for the L-shaped rod 401 to push the tire to the center of the placement plate 301.

[0037] Working principle: It should be noted that this device needs to be used in conjunction with a laser scanner. When in use, the tire is placed on the top of the placement plate 301. At this time, the driving motor 203 drives the transmission plate 304 to rotate. When the transmission plate 304 rotates, it will push the four sliding blocks 303 to slide away from each other in the four first strip grooves 302 through the four second strip grooves 305, thereby driving the four L-shaped rods 401 to move away from each other. The sliding of the L-shaped rod 401 will drive the contact block 501 to contact the inner mouth of the tire. At this time, the contact block 501 will be squeezed and enter the vertical groove 403, and the two limit springs 502 will also be compressed into the two second circular grooves 404. At this time, the four L-shaped rods 401 can form a push against the inner mouth of the tire through the four contact blocks 501. When the contact block 501 is engaged with the vertical groove 403, it will push the cross bar 503 and the fixed rod 505 to slide. When the fixed rod 505 slides, it will push the sliding block 501 through the guide groove 602. When the movable plate 601 slides downward, the insertion rod 603 is driven to slide downward. When the contact block 501 slides to the end of the vertical groove 403, the insertion rod 603 will just slide to the disengagement hole 704. At this time, the contact rod 701 will be unlocked, and the ejection spring 703 will be released and push the contact rod 701 to slide out of the first circular groove 402. The contact rod 701 will contact the inner wall of the tire during the sliding process, and form a push against the inner wall of the tire through the thrust of the ejection spring 703. At this time, the motor at the bottom of the workbench 1 is started to drive the rotating disk 201 to rotate, which can drive the tire to rotate. At this time, the laser scanner is started to start the detection. Through the first contact component 5 and the second contact component 7, the four contact blocks 501 and the four contact rods 701 will simultaneously push against the inner mouth and the inner wall of the tire. Compared with the prior art that only pushes against the inner mouth of the tire, the stability of the push is improved to a certain extent, and the tire is prevented from shaking during the detection process.
