Description

Technical Field

[0001] This utility model relates to the field of automobile tailgate inspection, and in particular to a height-adjustable support device. Background Technology

[0002] The tailgate is an important component of a car, mainly composed of tailgate sheet metal parts, door trim panels installed on the inside of the tailgate, and rear window glass. To ensure the assembly accuracy of the tailgate door trim panels and rear window glass on the tailgate sheet metal parts, after the tailgate sheet metal parts are stamped, they need to be placed and fixed on a dedicated tailgate inspection platform to inspect the contour structure, assembly hole positions, and contour accuracy of the tailgate sheet metal parts.

[0003] Typically, the sheet metal parts of a car's tailgate are suspended and mounted on a car tailgate inspection platform. This type of inspection platform has support columns fixedly installed to support the car tailgate. The top of the support columns is equipped with limiting posts that fit into the mounting holes on the upper part of the car tailgate sheet metal parts. The car tailgate sheet metal parts are placed on the support columns pre-positioned on the inspection platform, and some downward mounting holes fit into the limiting posts on the support columns at predetermined positions. The support columns provide support and limit the movement of the parts. At the same time, the top of the car tailgate sheet metal parts is clamped by quick-press clamps pre-set on the inspection platform to ensure the stability of the car tailgate sheet metal parts when they are flipped and inspected on the inspection platform.

[0004] However, the positions of existing support columns and limit columns installed on the support columns are fixed. A car tailgate inspection platform usually requires several support columns, but the height of the support columns used on the same car tailgate inspection platform is not uniform. It needs to be adapted to the height requirements of different parts of the car tailgate sheet metal parts. Therefore, it is necessary to develop support columns that meet different height requirements. The height of such support columns is uniform and cannot be adjusted. Car tailgate sheet metal parts with different structures need to be placed on the inspection table for testing, which requires support columns of different heights. It is inflexible, has poor versatility, and increases the research and development and use costs. Summary of the Invention

The guide post 35 is vertically inserted into the guide hole 331 and slides vertically with the guide hole 331. The lower end of the guide post 35 is located inside the elastic limiting hole 332. To give the guide post 35 vertical elasticity, a spring 36 is sleeved on the part of the guide post 35 located inside the elastic limiting hole 332. The outer diameter of the spring 36 is larger than the diameter of the guide hole 331 but smaller than the diameter of the elastic limiting hole 332. The top of the spring 36 abuts against the top of the elastic limiting hole 332. (Refer to the appendix of the instruction manual.) Figure 5 As shown, a limiting block 351 is provided at the bottom of the guide post 35. The limiting block 351 is integrally formed with the guide post 35 or connected by a threaded connection. The diameter of the limiting block 351 is larger than the diameter of the spring 36 but smaller than the diameter of the elastic limiting hole 332. The bottom of the spring 36 abuts against the outer part of the limiting block 351 on the guide post 35. It should be noted that the limiting block 351 connected to the bottom of the guide post 35 is always inside the elastic limiting hole 332 and will not protrude below the bottom of the insertion post 32, ensuring that the limiting block 351 will not interfere with the bottom of the connecting hole 211 on the connecting seat 2 after the adjustable support 3 is installed on the connecting seat 2. The top of the adjusting seat 31 is movably provided with a support post 34 that can adjust the height position. The bottom center of the support post 34 is fixedly connected to the top of the guide post 35. The support post 34 and the guide post 35 can be fixedly connected by a threaded connection for easy disassembly. See the appendix of the instruction manual. Figure 5 As shown, the support column 34 consists of a support block 341 and a locking block 342. The support block 341 is a vertical cuboid structure, and the locking block 342 is a horizontal cuboid structure. The support block 341 and the locking block 342 are integrally formed. The support block 341 is located at the top of the locking block 342 near one end, and its side has an "L" shape. The guide post 35 is connected to the bottom of the locking block 342, and its position corresponds vertically to that of the support block 341. For convenient adjustment of the height of the support column 34 on the adjusting seat 31, please refer to the appendix of the instruction manual. Figure 3As shown, the top of the adjusting seat 31 is provided with a stepped groove, which has a cross-shaped structure. This stepped groove consists of a first height groove 311 and a fourth height groove 314 arranged longitudinally, and a second height groove 312 and a third height groove 313 arranged laterally. The first height groove 311 and the fourth height groove 314 are connected front to back and pass through the center of both sides of the adjusting seat 31. The height of the fourth height groove 314 is higher than the height of the first height groove 311. The second height groove 312 and the third height groove 313 are connected left to right and pass through the center of both sides of the adjusting seat 31. The height of the second height groove 312 is higher than the height of the third height groove 313 but lower than the height of the fourth height groove 314. The length of the first height groove 311 matches the length of the locking block 342, and the tensioning hole 33 is located within the first height groove 311. It is clear that the widths of the first height groove 311, the second height groove 312, the third height groove 313, and the fourth height groove 314 are the same. When the support column 34 is inserted into any one of the height grooves and lifted upwards, the locking block 342 on the support column 34 can be engaged in the height groove of the required height. When the support column 34 is released, under the tension of the spring 36, the guide column 35 drives the support column 34 to return to its original position downwards, ensuring the stability of the position of the support column 34. In order to facilitate the fixed connection of the adjusting seat 31 on the connecting seat 2 and prevent it from shifting after installation, the top of the adjusting seat 31 is provided with a vertically connected mounting hole 315 located on the outer side of the stepped groove. The mounting hole 315 is a countersunk hole or a threaded hole, and its number and position correspond vertically to the number and position of the fixed connection hole 213 on the top of the connecting seat 2. They are fixedly connected together by bolts, making disassembly and assembly convenient.

[0031] The specific usage method is as follows: First, the base 1 is fixedly installed on the car tailgate testing platform using bolts. Based on the parts of the car tailgate sheet metal that require support, the corresponding connecting seat 2 is installed on the base 1. The connecting seat 2 is fixedly installed on the top of the base 1 using bolts. Next, the adjustable support seat 3 is installed on the connecting seat 2. The adjusting seat 31 is inserted into the connecting hole 211 of the connecting seat 2 via the plug-in post 32 and fixed with bolts. The height of the support post 34 on the adjusting seat 31 is manually adjusted. During adjustment, the support post 34 is lifted upwards, causing the guide post 35 to move upwards synchronously. At this time, the spring 36 located in the elastic limiting hole 332 moves upwards synchronously with the limiting stop 351, and the top of the spring 36... The part is restricted. As the guide post 35 is pushed upward, the spring 36 is compressed, and then the support post 34 is rotated to place the locking block 342 into any height groove of the required height. Then the support post 34 is released. Without the action of upward force, the upward-contracted spring 36 opens downward and drives the guide post 35 downward. The guide post 35 drives the support post 34 at its top downward, so that the support post 34 is stable in the corresponding height groove, ensuring the stability of the position. Then the car tailgate sheet metal part to be tested is placed on the testing platform. The top of the support block 341 on the support post 34 cooperates with the corresponding assembly on the car tailgate sheet metal part for support and limitation. At the same time, the top of the car tailgate sheet metal part is clamped by the quick-press clamp 4. Refer to the instruction manual appendix. Figure 6 As shown, the clamping part of the quick-press clamp 4 corresponds vertically to the top of the support block 341 to prevent uneven loading and deformation of the car tailgate sheet metal parts, and to fix the car tailgate sheet metal parts on the testing platform.

[0032] In this height-adjustable support device, the height of the support column 34 can be adjusted on the adjustment seat 31 as needed. With the height of the base 1 fixed, different connecting seats 2 can be used to facilitate the support and positioning of different support parts at the bottom of the car tailgate sheet metal parts. The base 1 and the adjustable support seat 3 are highly versatile, making them more flexible to use and reducing development and usage costs.

[0033] It should be emphasized that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
