[0022] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0023] according to Figure 1-5As shown, this embodiment proposes a solution: an adjustable car wheel arch contour comparison fixture bracket, including a fixture bracket body 1, a fixed frame 2 fixedly installed on the top of the fixture bracket body 1, a lifting plate 3 slidably connected to the inner side of the fixed frame 2, hydraulic cylinders 4 for driving the lifting plate 3 to slide up and down fixedly installed on the top of the fixed frame 2 near the left and right sides, two first clamping members 5 rotatably connected to the bottom of the lifting plate 3, a rotating opening 6 is opened on the top of the fixture bracket body 1 and at the bottom of the first clamping members 5, a rotating seat 7 is rotatably connected to the inner side of the rotating opening 6, a second clamping member 8 adapted to the first clamping member 5 is fixedly installed on the top of the rotating seat 7, a first scale line 9 is opened on the top of the left rotating seat 7 near the side wall, a size detection component is provided on the inner side of the first clamping member 5 for comparing the size difference of the two car wheel arches, and a positioning component is provided on the inner side of the fixture bracket body 1 near the left side for fixing the left rotating seat 7.

[0024] In this implementation case, a standard car wheel cover and a car wheel cover to be tested are placed on top of the second clamping member 8 at the top of the main body 1 of the inspection fixture. The hydraulic cylinder 4 is activated, and the hydraulic cylinder 4 drives the lifting plate 3 to slide up and down inside the fixed frame 2. The lifting plate 3 is adjusted to a suitable height so that the bottom of the first clamping member 5 is in contact with the top of the car wheel cover. Thus, the two car wheel covers are clamped and limited by the first clamping member 5 and the second clamping member 8. This can adapt to the installation size requirements of wheel covers of different models and sizes, effectively solving the problem that some existing inspection fixtures cannot be used to inspect wheel covers of different sizes. This significantly improves the applicability and inspection efficiency of the device. At the same time, the size difference between the two car wheel covers is compared and inspected by the size detection component. The first clamping member 5 and the rotating seat 7 can be manually rotated according to the curvature of the wheel cover surface to adjust the angle of the wheel cover so that the curvature of the wheel cover matches the inspection requirements. The rotation angle can be observed through the first scale line 9 on the top of the left rotating seat 7. After adjustment, the rotating seat 7 is limited by the positioning component to facilitate subsequent comparison and inspection.

[0025] Support legs 10 are fixedly installed at the bottom of the main body 1 of the inspection fixture near the four corners. A groove is opened on the top of the main body 1 of the inspection fixture and in front of the left rotating seat 7. An indicator 11 is fixedly installed inside the groove. Through the function of the indicator 11 and the first scale line 9, the operator can accurately control the rotation angle and further improve the accuracy of the angle adjustment.

[0026] Two rotating grooved wheels 12 are rotatably connected to the bottom of the fixture support body 1. The two rotating grooved wheels 12 are connected by belt drive. The top of the rotating grooved wheel 12 passes through the inner side of the fixture support body 1 and is fixedly connected to the bottom of the rotating seat 7. When it is necessary to adjust the angle of the two rotating seats 7 synchronously, rotating one of the rotating seats 7 will drive the other rotating grooved wheel 12 to rotate synchronously due to the belt drive connection between the two rotating grooved wheels 12, thereby driving the rotating seat 7 to rotate synchronously, realizing the synchronous adjustment of the angle of the two wheel covers. This reduces the operation steps and time, and further demonstrates the convenience of operation and the detection efficiency of the device.

[0027] The size detection component includes a connecting frame 13. The bottom of the connecting frame 13 is fixedly connected to the top of the adjacent first clamping member 5. A sliding sleeve 14 is fixedly installed at the bottom of the connecting frame 13. A sliding rod 15 is provided through the bottom end of the sliding sleeve 14 and is slidably connected to it. The bottom end of the sliding rod 15 passes through the inner side of the first clamping member 5 and a sliding block 16 is fixedly installed thereon. A second scale line 17 is opened on the front side of the sliding rod 15. During the descent of the first clamping member 5, the sliding block 16 will first contact the top of the car wheel cover. Then, the sliding block 16 will drive the sliding rod 15 to slide upward inside the sliding sleeve 14. By observing the second scale line 17 on the front side of the sliding rod 15, the values ​​of the corresponding positions of the standard wheel cover and the wheel cover to be tested can be read and compared. This allows for a quick and intuitive comparison of the size differences between the two car wheel covers.

[0028] The bottom of the first clamping member 5 has a notch that matches the sliding block 16. The top of the inner side of the sliding sleeve 14 is fixedly installed with a spring 18 that drives the sliding rod 15 to descend. The notch allows the sliding block 16 to be completely stored inside.

[0029] The positioning assembly includes a rotating sleeve 19, the rear end of which is rotatably connected to the front side of the fixture support body 1. A positioning rod 20 is threaded through the inner side of the rotating sleeve 19. A connecting hole is provided on the inner side of the fixture support body 1, allowing the positioning rod 20 to slide back and forth. Multiple positioning holes 21 adapted to the positioning rod 20 are provided on the side wall of the left rotating seat 7. A handle is fixedly installed on the circumference of the rotating sleeve 19. After the angle of the rotating seat 7 is adjusted, the handle is turned to drive the rotating sleeve 19 to rotate. Since the positioning rod 20 is threadedly connected to the rotating sleeve 19, the positioning rod 20 slides back and forth in the connecting hole, inserting the positioning rod 20 into the adjacent positioning hole 21 on the side wall of the left rotating seat 7, thereby fixing and limiting the position of the rotating seat 7 and preventing it from rotating during the inspection process.

[0030] The above embodiment discloses an adjustable car wheel arch contour comparison fixture bracket. A standard car wheel arch and the car wheel arch to be tested are placed on top of the second clamping member 8 at the top of the fixture bracket body 1. The hydraulic cylinder 4 is activated, driving the lifting plate 3 to slide up and down inside the fixed frame 2. The lifting plate 3 is adjusted to a suitable height, so that the bottom of the first clamping member 5 is in contact with the top of the car wheel arch. Thus, the first clamping member 5 and the second clamping member 8 limit and clamp the two car wheel arches, adapting to the installation size requirements of wheel arches of different models and sizes. This effectively solves the problem that some existing fixture brackets cannot inspect wheel arches of different sizes, significantly improving the applicability and inspection efficiency of the device. During the descent of the first clamping member 5, the sliding block 16 will first contact the top of the car wheel arch. Then, the sliding block 16 will drive the sliding rod 15 to slide upwards inside the sliding sleeve 14. Observe the second scale line 17 on the front side of the sliding rod 15. By reading and comparing the corresponding values ​​of the standard wheel cover and the wheel cover to be tested, the size differences between the two car wheel covers can be quickly and intuitively compared. When it is necessary to adjust the angle of the two rotating seats 7 simultaneously, rotating one of the rotating seats 7 will drive the other rotating wheel 12 to rotate synchronously due to the belt drive connection between the two rotating groove wheels 12, thereby driving the rotating seat 7 to rotate synchronously, realizing the synchronous adjustment of the angle of the two wheel covers. Through the function of the indicator 11 and the first scale line 9, it is easy for the operator to accurately control the rotation angle, further improving the accuracy of the angle adjustment. After the angle of the rotating seat 7 is adjusted, turn the handle to drive the rotating sleeve 19 to rotate. Since the positioning rod 20 is threadedly connected to the rotating sleeve 19, the positioning rod 20 slides back and forth in the connecting hole, inserting the positioning rod 20 into the positioning hole 21 adjacent to the side wall of the left rotating seat 7, thereby fixing and limiting the position of the rotating seat 7 to prevent it from rotating during the testing process.
