Description

Technical Field

[0001] The utility model relates to the technical field of clamping and positioning of front wheel covers, in particular to a clamper for a front wheel cover. Background Art

[0002] As an integral part of the vehicle's body structure, the front wheel cover is installed above the front wheel. Its primary function is to position and protect the front wheel, ensuring stable wheel rotation. It also provides necessary protection from dust and stones thrown up by the wheels during driving, effectively reducing the risk of paint damage and thus helping to extend the vehicle's overall service life. Furthermore, the design of the front wheel cover is not limited to practicality; it also incorporates aesthetic elements. Its streamlined appearance not only enhances the vehicle's overall visual appearance but also improves its aerodynamic performance. The front wheel cover also plays a vital role in reducing noise and vibration. It helps absorb and isolate the noise and vibration generated by the rotating tires, providing a more comfortable and quiet driving experience for the driver and passengers. Furthermore, the structural design of the front wheel cover is crucial for supporting and securing the front suspension assembly. Its precise matching of the assembly dimensions with the front suspension axle directly affects the vehicle's overall stiffness, modal characteristics, seismic strength, and crash safety performance.

[0003] In the front body assembly of a vehicle, the assembly position of the front wheel housing determines the assembly position of the front wheels, which in turn directly affects the alignment of the front wheels. Front wheel alignment includes the front wheel camber angle, kingpin inclination angle, caster angle, and vehicle toe. Front wheel alignment ensures the vehicle maintains stability and easy steering during straight-line driving, and automatically returns to its original position even when the steering wheel is deflected by external forces. Therefore, after undergoing multiple processing steps such as stamping, cutting, trimming, and welding, the front wheel housing must be inspected to ensure that it meets the requirements of the front body assembly. Given that the front wheel housing is a typical saddle-shaped cover with a complex shape, large wheel size, thin material, and high surface quality requirements, the use of measuring tools to inspect the multiple positions of the front wheel housing is particularly important. To facilitate the positioning of the front wheel housing, a corresponding clamp is designed based on the internal structure of the front wheel housing to quickly position the front wheel housing. Specifically, a test fixture is designed to fit the interior structure of the front wheel housing to ensure proper positioning. The front wheel housing is then secured to the fixture with a clamp to facilitate verification. However, the clamp's lack of flexibility makes it difficult to adjust the securing method for the front wheel housing, impacting the reliability of the verification results. Furthermore, due to the complex shape of the front wheel housing, comprehensive verification from a single direction is difficult. Once the front wheel housing is assembled on the clamp, however, its position is difficult to adjust, making verification a cumbersome task. Therefore, there is room for improvement in the clamping mechanism to facilitate clamping and securing the front wheel housing, as well as to facilitate adjustment of the verification direction, thereby improving verification efficiency.

The two sides of the support block 15 are respectively installed on the first clamp 5 and the insert plate 4. A first threaded hole is horizontally opened on the support block 15. A bolt 16 is threadedly sleeved on the inner thread of the first threaded hole. One end of the bolt 16 contacts the arc surface of the inspection fixture 2. The support block 15 and the insert plate 4 are squeezed between the inspection fixture 2 and the first guide rail 3 by the bolt 16 to facilitate the fixation of the first clamp 5 and the insert plate 4.

[0024] Please refer again Figure 1 、 4 and 5. A cover plate 17 is provided below the fixed plate 6. One side of the fixed plate 6 is hinged to the cover plate 17 by a hinge. A telescopic cylinder 18 is provided on the other side of the support plate 1. The two sides of the telescopic cylinder 18 are respectively hinged to the cover plate 17 and the fixed plate 6.

[0025] Specifically, a support 19 is provided under the cover 17, and a driving motor 20, a screw rod 21 and a second guide rail 22 are respectively provided on the support 19. The second guide rail 22 and the screw rod 21 are parallel to each other.

[0027] The method of using this product is as follows: Figures 1 to 5 As shown, first, the front wheel cover is guided by the guide groove 14 and placed on the top surface of the inspection fixture 2, ensuring that the two sides of the front wheel cover are in contact with the first positioning strip 11 and the second positioning strip 12 respectively, so that the inner cavity surface of the front wheel cover is tightly fitted on the top surface of the inspection fixture 2. Next, the second clamp 13 is operated to squeeze one side of the front wheel cover to fix one side of the front wheel cover to the support plate 1, and then the position of one side of the plug plate 4 on the first guide rail 3 is adjusted, and the first clamp 5 is operated to squeeze the other side of the front wheel cover to fix the other side of the front wheel cover to the support plate 1. Then, by running the drive motor 20, the screw rod 21 pushes the cover plate 17 to move along the second guide rail 22 to push the cover plate 17 into the inspection area, and by controlling the telescopic cylinder 18 to extend, the fixed plate 6 is driven to rotate around the cover plate 17, thereby driving the inspection fixture 2 and the front wheel cover to tilt, so as to facilitate the use of the measuring tool to detect the front wheel cover. Subsequently, according to the requirements of the front wheel cover inspection part, the drive rod of the stepper motor 7 is controlled to perform the rated angular displacement, and the driving gear 9 and the driven gear 10 are used for transmission, driving the support plate 1, the inspection fixture 2 and the front wheel cover to rotate as required, so as to facilitate the use of the inspection fixture to fully inspect the front wheel cover. Finally, after the front wheel cover is inspected, the control sequentially controls the stepper motor 7 and the telescopic cylinder 18 to reset, and then reverses the drive motor 20 to make the screw 23 push the cover plate 17 back to the placement area of ​​the front wheel cover, so that the front wheel cover can be removed from the inspection fixture 2.

[0028] In this embodiment, the first guide rail 3 provided on the curved surface of the inspection fixture 2 limits the position of the inserting plate 4, so that the inserting plate 4 and the first clamp 5 can only move along the curved surface of the inspection fixture 2, thereby improving the flexibility of the first clamp 5. This allows the position of the first clamp 5 holding the front wheel housing to be adjusted according to the inspection needs, thereby improving the reliability of the front wheel housing inspection. In addition, the stepping motor 7, driving gear 9, and driven gear 10 provided in this embodiment can drive the support plate 1 and the inspection fixture 2 to rotate about the fixed plate 6, thereby facilitating comprehensive inspection of the clamped front wheel housing in a single direction and reducing the tediousness of the front wheel housing inspection work.
