[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0022] It should be noted that in the description of the present invention, if terms such as "front", "rear", "up", and "down" appear to indicate directions or positional relationships, they are based on the directions or positional relationships of the luggage rack installed on the roof, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention.
[0023] Please also refer to Figures 1 to 3 The luggage rack checker provided by the present invention is now described. The luggage rack checker comprises a base 1, a support frame, and a clamping mechanism 5. The support frame is provided with a contoured groove 31 adapted to fit the luggage rack 2. Multiple clamping mechanisms 5 are disposed on the base 1 and dispersed along the contoured groove 31. The clamping mechanisms 5 are provided with a pressing plate 7 that moves downward from top to bottom to compress the luggage rack 2.
[0024] The luggage rack inspection fixture provided by the present invention is used by placing the luggage rack 2 in the contoured groove 31, and utilizing the pressing mechanism 5 to drive the pressing plate 7 to move from top to bottom, so that the luggage rack 2 can be pressed in the contoured groove 31. There is no need to tighten the bolts one by one, and the luggage rack 2 can be quickly pressed to facilitate inspection of the luggage rack 2, thereby shortening the operation time of pressing the luggage rack 2, thereby improving inspection efficiency. At the same time, since the inspector does not need to operate multiple bolts, the labor intensity of the inspector is also reduced.
[0025] In addition, the fast clamping method of the clamping mechanism 5 does not require bolt connection, so there is no need to apply glue to the bolts and repair and re-apply thread glue, which improves the operational efficiency of the luggage rack 2 clamping.
[0026] In this embodiment, the number of the pressing mechanisms 5 and the locations of the pressing points need to be consistent with the assembly connection points of the entire vehicle to restore the assembly effect of the entire vehicle.
[0027] In some embodiments, see Figures 1 to 3As shown, the clamping mechanism 5 is any one of a pneumatic cylinder, a hydraulic cylinder, and an electric push rod, and the pressure plate 7 is arranged on the telescopic rod of the clamping mechanism 5. The existing bolt connection fastening method is changed to a pneumatic or hydraulic clamping method. There is no need to tighten the bolts. The master control valve on the base is activated to operate the telescopic rod of the clamping mechanism 5 to drive the pressure plate 7 up and down, thereby clamping the luggage rack 2. This realizes one-button switch control, which is simple and convenient to operate. At the same time, the use of this clamping mechanism 5 has a telescopic function, so it can also adapt to the clamping of luggage racks 2 of different heights, which also greatly expands the application range of the inspection fixture. A set of inspection fixtures can be used to inspect luggage racks 2 of various specifications.
[0028] When the clamping mechanism 5 is a pneumatic cylinder, the cylinder is connected to an air source, its cylinder body is bolted to the base 1, its telescopic rod is extended and retracted upward, and the pressure plate 7 is bolted to the telescopic rod. To ensure the cylinder's vertical upright position and prevent the cylinder body from tilting, a reinforcement plate may be provided on one or both symmetrical sides of the cylinder body. This not only maintains the verticality of the cylinder body but also ensures the vertical extension and retraction trajectory of the telescopic rod, thereby ensuring that the pressure plate 7 remains horizontally pressed against the luggage rack 2, improving the reliability of the clamping mechanism. Furthermore, to ensure the horizontal clamping of the pressure plate 7, the cylinder is designed with two telescopic rods. This not only provides a reliable horizontal support surface for the pressure plate 7, but also provides a secure mounting surface for the fastening of the pressure plate 7 to the telescopic rods. Of course, support blocks are provided at the upper ends of the two telescopic rods, to which the pressure plate 7 is fixed. This further increases the support surface provided by the cylinder for the pressure plate 7, thereby ensuring the horizontal clamping state of the pressure plate 7.
[0029] Similarly, when the clamping mechanism 5 is a hydraulic cylinder, the hydraulic cylinder only needs to be connected to a hydraulic power source. Other situations are similar to those of the air cylinder and will not be described in detail.
[0030] When the pressing mechanism 5 is an electric push rod, it is sufficient to connect the motor of the electric push rod to a power source.
[0031] Optionally, the clamping mechanism 5 is a worm gear lifting mechanism, which can also realize the lifting and clamping of the pressure plate 7. Moreover, the worm gear lifting mechanism also has a good self-locking function. When the pressure plate 7 presses the luggage rack 2, it is not easy to loosen, thereby providing a guarantee for the inspection result of the luggage rack 2.
[0032] In some embodiments, see Figures 1 to 3As shown, a buffer block 6 is provided below the pressure plate 7 to press against the luggage rack 2. The buffer block 6 has an arc-shaped surface that matches the upper surface of the luggage rack 2. The buffer block 6 has good deformation properties. When pressed against the luggage rack 2, the deformability of the buffer block 6 can prevent the luggage rack 2 from being scratched and damaged by hard objects. The covering function of the buffer block 6 can also increase the contact area with the luggage rack 2, thereby improving the reliability of the pressing. In addition, the buffering performance of the buffer block 6 can also prevent the impact on the luggage rack 2 when the pressure plate 7 is pressed down, protecting the luggage rack 2 from damage.
[0033] In some embodiments, see Figures 1 to 3 As shown, the buffer block 6 is made of rubber or silicone. Specifically, the buffer block 6 can be made of a solid rubber or silicone member, and the material used can be selected to obtain buffer blocks 6 with different elasticities. Alternatively, the buffer block 6 can also be provided with a spring between the rubber pad and the pressure plate 7 to achieve cushioning performance.
[0034] In some embodiments, see Figures 2 to 3 As shown, each clamping mechanism 5 is respectively provided with a control valve (not shown in the figure) that can adjust its own clamping force, and a master control valve 10 that controls the simultaneous opening and closing of each clamping mechanism 5 is provided on the base 1. Although the master control valve 10 can be used to open and close each clamping mechanism 5 with one button, by setting a control valve for each clamping mechanism 5, the respective clamping forces can be adjusted individually according to the position of each clamping mechanism 5 and the required clamping force, so as to be able to truly restore the clamping effect of different connection points after assembly. Specifically, after opening the master control valve 10, each clamping mechanism 5 can adjust a certain preload force at the same time, and then adjust the respective control valves individually to obtain the clamping force of each connection point, so as to be able to restore the stress deformation after assembly of the entire vehicle; when it needs to be closed, the master control valve 10 can be closed with one button to achieve rapid closure of all clamping mechanisms 5, thereby improving the clamping efficiency of the inspection fixture. After tightening, the luggage rack 2 can be inspected, for example, the gap between the luggage rack 2 and the front windshield profiling block, the overlap between the luggage rack 2 and the sheet metal profiling, the gap between the luggage rack 2 and the tailgate, the position of the square head bolts, and the gap between the aluminum tube and the gasket can be inspected.
[0035] Optionally, the master control valve 10 is a pneumatic valve, a hydraulic control valve, a solenoid valve, or an electric button. When the clamping mechanism is a pneumatic cylinder or a hydraulic cylinder, the master control valve 10 is installed on the main pipeline, and the control valves are installed on each branch pipeline connected to the main pipeline. When the clamping mechanism is electrically driven, the master control valve 10 is installed on the main control line, and the control valves are installed on the branch lines. In this case, both the master control valve and the control valve can be electrically switched.
[0036] In some embodiments, see Figures 1 to 3As shown, the support frame includes a support 8 and a contour frame 3 mounted on the support 8. The contour frame 3 is provided with a contour groove 31. The support 8 is mounted on the base 1. Multiple supports 8 are dispersed and evenly arranged along the length of the luggage rack 2 to ensure that the luggage rack 2 is in the same state as when installed on the roof during inspection.
[0037] In some embodiments, see Figures 1 to 3 As shown, the support frame also includes lifting seats 4 disposed at both ends of the contour frame 3. The lifting seats 4 are provided with stoppers 9 that abut the front and rear end surfaces of the luggage rack 2. If the front and rear elbows of the luggage rack 2 to be inspected are slightly different in height, the height of the lifting seats 4 can be adjusted so that the stoppers 9 form front and rear limits for the ends of the luggage rack 2.
[0038] In some embodiments, see Figures 1 to 3 As shown, the lifting base 4 includes a slide 41 fixed to the base 1 and a slide 43 that slides into the slide 41. The slide 43 is locked to the slide 41 by a locking screw 42. A stopper 9 is provided at the upper end of the slide 43. To adjust the height of the slide 43, loosen the locking screw 42, slide the slide 43 up or down to the desired position, and then tighten the locking screw 42.
[0039] Optionally, the lifting seat 4 is a screw and nut lifting mechanism, a worm gear lifting mechanism or a cylinder lifting mechanism.
[0040] In some embodiments, see Figure 2 As shown, one of the stop blocks 9 is provided with a support step on the side facing the luggage rack 2, and one end of the luggage rack 2 can be overlapped on the support step. For example, the stop block 9 at the front end of the luggage rack 2 is provided with a support step. The support step and the vertical surface of the stop block 9 form a front positioning and a downward positioning for the luggage rack 2, which effectively defines the position of the luggage rack 2.
[0041] In some embodiments, see Figures 2 to 3 As shown, the support 8 includes a bottom plate 83 , a vertical plate 84 arranged on the bottom plate 83 , and a supporting plate 81 arranged on the vertical plate 84 , and the contour frame 3 is supported on the supporting plate 81 .
[0042] Alternatively, the support 8 may be a cylindrical, rectangular, or elliptical cylinder. This embodiment is preferably made of sheet metal, which is simple to manufacture and lightweight. The bottom plate 83 makes extensive contact with the base 1, providing reliable support. The top support plate 81 also makes extensive contact with the contour frame 3, providing reliable support for the contour frame 3. To enhance support strength, a fin plate 82 is provided between the bottom plate 83 and the support plate 81, perpendicular to the vertical plate 84. The fin plate 82 is perpendicular to and connected to the vertical plate 84, or parallel to the vertical plate 84.
[0043] The bottom plate 83 is fixed to the base 1 by screws for easy disassembly, the vertical plate 84 and the fin plate 82 can be welded between the bottom plate 83 and the supporting plate 81 , and a limiting groove can be provided on the supporting plate 81 to fix the contour frame 3 .
[0044] Optionally, the profiling frame 3 is segmented, and a support 8 is provided below each segment of the profiling frame 3 .
[0045] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
