Description

Technical Field

[0001] The utility model relates to the technical field of automobile wheel fixing, in particular to a wheel body fixing device for automobile testing. Background Art

[0002] A wheel is a rigid wheel that secures the inner rim of the tire, supports the tire, and shares loads with the tire. The tire, rim, and spokes combined together are collectively referred to as a wheel. The wheel assembly consists of two major components: the wheel and the tire.

[0003] Since wheels directly bear the various complex loads generated by cars and roads, for safety reasons, they need to undergo various tests after production, such as compression tests. During the test, the wheels are observed to see if there are any local permanent damage or cracks to ensure the safety of the product.

[0004] Currently, when testing wheels, most of the time, a two-side clamping method is used to clamp and fix the wheel. This method easily causes the center of the wheel to be not in the center of the testing machine, affecting the accuracy of the test results. In addition, the clamped wheel cannot be rotated after being fixed. After the positioning is released, the worker needs to manually rotate the wheel, which is a cumbersome, time-consuming and labor-intensive operation. Utility Model Content

Under the action of the driving mechanism 200, the four sliders 130 can simultaneously drive the clamping blocks 140 to approach each other to clamp and fix the wheel. In the process of clamping, the wheel will be corrected to be located in the center to ensure the accuracy of the test. A rotating mechanism 300 is provided inside the base 100.

[0023] Specifically, such as Figure 3 and Figure 4 As shown, a wheel body fixing device for automobile testing, the driving mechanism 200 includes a first rotating rod 210, a worm gear 220, a vertical plate 230, a first motor 240, a worm 250, a rotating platform 260, a mounting seat 270 and a connecting rod 280. The first rotating rod 210 is rotatably provided between the upper and lower inner walls of the circular platform 110. The lower end of the first rotating rod 210 is fixedly sleeved with a worm gear 220. One side of the lower inner wall of the circular platform 110 is fixedly connected to the vertical plate 230 and the other side is installed with the first motor 240. The output shaft end of the first motor 240 is fixedly connected to the worm 250 that cooperates with the worm gear 220. The other end is rotatably connected to the vertical plate 230. A rotating platform 260 is fixedly sleeved on the rod wall of the first rotating rod 210. Four mounting seats 270 are arranged on the circumferential wall of the rotating platform 260. A connecting rod 280 is rotatably provided on the mounting seat 270. The other end of the connecting rod 280 is rotatably connected to the bottom end of the slider 130. The output shaft of the first motor 240 can drive the worm 250 to rotate. When the worm 250 rotates, the worm gear 220 can drive the first rotating rod 210 to rotate. When the first rotating rod 210 rotates, it drives the rotating platform 260 to rotate. Under the action of the connecting rod 280, the four sliders 130 can simultaneously drive the clamping blocks 140 to approach each other.

[0024] Specifically, such as Figure 2 As shown, a wheel fixing device for automobile testing, the rotating mechanism 300 includes a second rotating rod 310, a driven gear 320, a second motor 330 and a driving gear 340. The second rotating rod 310 is rotatably provided on the lower inner wall of the base 100, and the upper end of the second rotating rod 310 is fixedly connected to the lower outer wall of the placement table 110.

The output shaft end of the second motor 330 is fixedly connected to the driving gear 340. The driving gear 340 meshes with the driven gear 320. When various tests are performed on different parts of the wheel, after the test of a part is completed, the output shaft of the second motor 330 can drive the driving gear 340 to rotate. The rotation of the driving gear 340 will drive the driven gear 320 to rotate. The rotation of the driven gear 320 drives the second rotating rod 310 to rotate, so that the placement table 110 drives the wheel to rotate, so that various tests on different parts of the wheel can be performed more conveniently and practically.

[0025] Specifically, such as Figure 2As shown, a wheel fixing device for automobile testing is provided. An annular guide groove 101 is provided on the upper outer wall of the base 100, and a plurality of balls 111 that cooperate with the annular guide groove 101 are provided around the bottom edge of the upper end of the placing table 110. When the placing table 110 rotates, the balls 111 roll in the annular guide groove 101, making the rotation of the placing table 110 more stable.

[0026] Specifically, such as Figure 1 As shown, a wheel fixing device for automobile testing is provided. A rubber protective pad 141 is provided on one side wall of the clamping block 140 near the center of the truncated table 110 to prevent wear on the tire during the clamping process, thereby protecting the tire.

[0027] When the present invention is implemented, when fixing the wheel, the wheel is placed on the placing table 110, and then the first motor 240 is started. The output shaft of the first motor 240 can drive the worm 250 to rotate. When the worm 250 rotates, the worm gear 220 can drive the first rotating rod 210 to rotate. When the first rotating rod 210 rotates, the rotating table 260 is driven to rotate. Under the action of the connecting rod 280, the four sliders 130 can simultaneously drive the clamping blocks 140 to approach each other, clamping and fixing the wheel, and the wheel will be corrected during the clamping process so that it is located in the center to ensure the accuracy of the test. When various tests are performed on different parts of the wheel, after the test of one part is completed, the output shaft of the second motor 330 can drive the driving gear 340 to rotate. The rotation of the driving gear 340 will drive the driven gear 320 to rotate. The rotation of the driven gear 320 drives the second rotating rod 310 to rotate, so that the placing table 110 drives the wheel to rotate, so that various tests can be performed on different parts of the wheel, which is more convenient and practical.
