Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive component testing technology, and in particular to an automotive roof testing fixture. Background Technology
[0002] A car roof is a structural and decorative component installed on the roof of a vehicle. It includes the main protective structure of the vehicle roof as well as the functional covering system of the interior layer. As a core safety component and important interior element of a car, it not only meets the requirements for the compressive strength of the roof, but also has the functions of sound insulation, heat insulation and decoration. Car interior roofs are generally made of plastic or fabric and need to be tested during the production process.
[0003] Existing automotive headliner inspection methods have the following drawbacks: In addition to the automatic inspection equipment commonly found on production lines, manual sampling is also required when inspecting automotive headliners. This mainly involves manual re-inspection of the surface cleanliness, opening positions, and dimensions of the headliner. Since automotive headliners are generally integral structures with a large area, traditional inspection fixtures that horizontally position the headliner are inconvenient for observing and inspecting the central area of the headliner, making them inconvenient to use. Therefore, we propose an automotive headliner inspection fixture. Utility Model Content
[0004] The main purpose of this utility model is to provide a tooling for inspecting car roofs. By cooperating with the positioning mechanism inside the ladder frame and the positioning frame, it is possible to conveniently carry out comprehensive inspection of the surface of the car roof, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vehicle roof inspection fixture includes a stepped frame, a positioning frame, and a vehicle roof. The vehicle roof has symmetrical handle grooves on both sides of its interior, and each handle groove has a mounting hole. The vehicle roof is mounted inside the positioning frame. The positioning frame has a positioning mechanism on its surface, including: Base plate: It is set at the bottom of the positioning frame to support the positioning frame, and a support rod is welded vertically at the top center of the base plate. A sleeve is sleeved on the top of the outer periphery of the support rod, and a spring is inserted between the top of the support rod and the top of the inner wall of the sleeve. The sleeve is fixed at the center of the bottom of the positioning frame and has a hollow structure at the bottom. A rubber ring is glued to the top of the outer periphery of the sleeve and the sleeve is inserted into the outer periphery of the rubber ring. Hanging rods: They are symmetrically installed on both sides of the inner wall of the positioning frame, and their installation positions correspond to the positions of the handle grooves. The ends of the hanging rods pass through the mounting holes, and the car roof is fixed to the inside of the positioning frame through the hanging rods.
[0006] Furthermore, it also includes an adjustment mechanism. An adjustment mechanism is provided at the connection between the hanging rod and the positioning frame. The adjustment mechanism includes a sliding groove, a slider, a crossbar, a screw groove, and a nut. The inner wall of the positioning frame has vertically opened sliding grooves on both sides, and a slider is inserted into each sliding groove. A crossbar is horizontally welded to the side of the slider, and a nut is screwed to the outer periphery of the crossbar near the slider through a screw groove. The end of the hanging rod is vertically welded to the end of the crossbar. The position of the hanging rod can be vertically adjusted in height along the sliding groove on the side of the positioning frame. When adjustment is needed, the nut is turned along the screw groove towards the hanging rod side, so that the nut is away from the sliding groove. The height position of the hanging rod and the spacing between the hanging rods can be adjusted vertically by sliding. After reaching the appropriate position, the nut is tightened in the opposite direction to make it fit against the side of the positioning frame. It works with the slider to fix the position of the crossbar and the hanging rod, adapting to the handle groove setting position on the surface of different specifications of car roofs and meeting different roof mounting needs.
[0007] Furthermore, a connecting plate is fixedly connected to the bottom of the stepped frame, and a guide groove is opened horizontally inside the connecting plate. A movable wheel is installed at the bottom of the base plate, and a limiting groove corresponding to the position of the movable wheel is opened inside the guide groove. An inclined plate is fixedly connected to both ends of the connecting plate. The movable wheel structure facilitates the movement of the positioning frame and the car roof. It is moved into the guide groove along the inclined plate. After being moved into place, the movable wheel is inserted into the limiting groove, thus fixing the position of the positioning frame. After the test is completed, the positioning frame can be pushed out by force.
[0008] Furthermore, the outer periphery of the rubber ring is fitted to the inner wall of the sleeve; the inner wall of the sleeve is fitted to the inner wall of the rubber ring, increasing the friction at the connection point, so that the positioning frame will not rotate arbitrarily at the top of the sleeve. During the inspection operation, since the groove restricts the position of the positioning frame, the orientation of the car roof can be flipped by forcefully rotating the positioning frame.
[0009] Furthermore, a groove is provided at the top of the hanging rod near its end, and the mounting hole is inserted into the groove; after the hanging rod passes through the mounting hole, the mounting hole is aligned with the groove, so that the connection position of the mounting hole falls into the groove, thereby positioning the car roof and preventing it from shifting.
[0010] Furthermore, a rubber pad is adhered to the surface of the nut facing the slider, and the rubber pad is located at the connection between the nut and the inner wall of the positioning frame; after the nut is tightened, the rubber pad structure increases the friction between the nut and the side of the positioning frame, thereby better fixing the position of the crossbar and the hanging rod.
[0011] Compared with existing technologies, this utility model has the following advantages: The car roof surface has handle groove structures on both sides, which are fixed to the top of the car's inner wall via mounting holes and fasteners. The handle groove positions are used to install interior handles. The positioning frame has a hanging rod structure inside. When a car roof is sampled, the hanging rod is aligned with the mounting holes, and the car roof is hung inside the positioning frame. Then, the positioning frame is slid to the inspection position inside the stepped frame. The positioning frame vertically positions the car roof. Inspectors can climb the stepped frame at different heights to inspect different positions of the car roof. When necessary, the positioning frame can be lowered to reduce the height of the car roof, allowing for comprehensive inspection of the car roof surface. Compared with existing inspection fixtures, this design offers advantages in manual inspection. During the inspection process, by vertically hanging the car roof, and using a stepped frame with a certain height difference and a height adjustment component at the bottom of the positioning frame, a comprehensive inspection and observation of different positions on the car roof surface can be carried out, improving the convenience of manual inspection. The position of the hanging rod can be vertically adjusted along the sliding groove on the side of the positioning frame. When adjustment is needed, the nut is turned along the screw groove towards the hanging rod side, so that the nut is away from the sliding groove, and the height position of the hanging rod and the spacing between the hanging rods can be adjusted vertically. After reaching the appropriate position, the nut is tightened in the opposite direction to make it fit against the side of the positioning frame, and it works with the slider to complete the fixation of the horizontal bar and the position of the hanging rod. This adapts to the handle groove setting position on the surface of car roofs of different specifications and meets the different roof mounting requirements. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figure 1-5 As shown, a car roof inspection fixture includes a stepped frame 1, a positioning frame 2, and a car roof 3. The car roof 3 has symmetrically arranged handle grooves 301 on both sides inside, and each handle groove 301 has a mounting hole 302 inside. The car roof 3 is hung inside the positioning frame 2. The positioning frame 2 has a positioning mechanism 4 on its surface, including: Base plate 401: It is set at the bottom of the positioning frame 2 to support the positioning frame 2, and a support rod 403 is vertically welded at the top center of the base plate 401. A sleeve 404 is sleeved on the top of the outer periphery of the support rod 403, and a spring 405 is inserted between the top of the support rod 403 and the top of the inner wall of the sleeve 404. Sleeve 407: Fixed at the bottom center of the positioning frame 2 and with a hollow internal bottom end; a rubber ring 406 is bonded to the top of the outer periphery of the sleeve 404 and the sleeve 407 is fitted into the outer periphery of the rubber ring 406. Hanging rod 408: It is symmetrically installed on both sides of the inner wall of the positioning frame 2 and its installation position corresponds to the position of the handle groove 301. The end of the hanging rod 408 passes through the mounting hole 302 and the car roof 3 is fixed to the inside of the positioning frame 2 through the hanging rod 408.
[0020] The system also includes an adjustment mechanism 5. An adjustment mechanism 5 is provided at the connection between the hanging rod 408 and the positioning frame 2. The adjustment mechanism 5 includes a slide groove 501, a slider 502, a crossbar 503, a screw groove 504, and a nut 505. Slide grooves 501 are vertically formed on both sides of the inner wall of the positioning frame, and sliders 502 are inserted into each slide groove 501. A crossbar 503 is horizontally welded to the side of the slider 502, and a nut 505 is screwed onto the outer periphery of the crossbar 503 near the slider 502 via a screw groove 504. The end of the hanging rod 408 is vertically welded to the end of the crossbar 503. The position can be adjusted vertically along the sliding groove 501 on the side of the positioning frame 2. When adjustment is needed, turn the nut 505 along the screw groove 504 toward the hanging rod 408 so that the nut 505 is away from the sliding groove 501. This allows for vertical sliding adjustment of the height of the hanging rod 408 and the spacing between the hanging rods 408. After reaching the appropriate position, tighten the nut 505 in the opposite direction so that it fits against the side of the positioning frame. This, together with the slider 502, completes the fixation of the position of the crossbar 503 and the hanging rod 408. This adapts to the setting position of the handle groove 301 on the surface of different specifications of car roof 3, meeting different roof mounting requirements.
[0021] The bottom of each of the stepped frames 1 is fixedly connected by a connecting plate 101, and a guide groove 102 is opened horizontally inside the connecting plate 101. The bottom of the base plate 401 is equipped with a movable wheel 402, and a limiting groove 103 corresponding to the position of the movable wheel 402 is opened inside the guide groove 102. Both ends of the connecting plate 101 are fixedly connected with inclined plates 104. The movable wheel 402 facilitates the movement of the positioning frame 2 and the car roof 3. It is moved into the guide groove 102 along the inclined plate 104. After being moved into place, the movable wheel 402 is inserted into the limiting groove 103, thus fixing the position of the positioning frame 2. After the test is completed, the positioning frame 2 can be pushed out by force.
[0022] The outer periphery of the rubber ring 406 is fitted to the inner wall of the sleeve 407. A groove 409 is provided at the top of the hanging rod 408 near its end. The mounting hole 302 is hung inside the groove 409. The inner wall of the sleeve 407 is fitted to the inner wall of the rubber ring 406, which increases the friction at the connection point, so that the positioning frame 2 will not rotate arbitrarily at the top of the sleeve 404. During the inspection operation, since the groove 409 restricts the position of the positioning frame, the orientation of the car roof 3 can be flipped by forcefully rotating the positioning frame 2. After the hanging rod 408 passes through the inside of the mounting hole 302, the mounting hole 302 is aligned with the groove 409, so that the connection position of the mounting hole 302 falls into the inside of the groove 409, thereby positioning the car roof 3 and preventing it from shifting.
[0023] The nut 505 has a rubber pad 506 bonded to the side facing the slider 502. The rubber pad 506 is located at the connection between the nut 505 and the inner wall of the positioning frame 2. After the nut 505 is tightened, the rubber pad 506 increases the friction between the nut 505 and the side of the positioning frame 2, thereby better fixing the position of the crossbar 503 and the hanging rod 408.
[0024] It should be noted that this utility model is a tooling for inspecting car roofs. In use, the car roof 3 has handle grooves 301 on both sides of its surface. These grooves are fixed to the top of the car's inner wall via mounting holes 302 and fasteners. The handle grooves 301 are used to install interior door handles. The positioning frame 2 has a hanging rod 408 inside. When a car roof 3 is randomly selected for inspection, the hanging rod 408 is aligned with the mounting holes 302, and the car roof 3 is hung inside the positioning frame 2. Then, the positioning frame 2 is slid to the inspection position inside the stepped frame 1. The positioning frame 2 vertically positions the car roof 3. Inspectors can climb the stepped frame 1 at different heights to inspect different positions of the car roof 3. When necessary, the positioning frame 2 can be lowered to reduce the height of the car roof 3, allowing for comprehensive inspection of the car roof 3's surface. Compared to existing inspection tooling, this design offers advantages in manual re-inspection processes. By vertically hanging the car roof 3, and in conjunction with the stepped frame 1 with a certain height difference and the height adjustment component at the bottom of the positioning frame 2, comprehensive inspection and observation of different positions on the surface of the car roof 3 can be carried out, improving the convenience of manual inspection. The position of the hanging rod 408 can be vertically adjusted along the sliding groove 501 on the side of the positioning frame 2. When adjustment is needed, the nut 505 is turned along the screw groove 504 towards the hanging rod 408, so that the nut 505 is away from the sliding groove 501. The height position of the hanging rod 408 and the spacing between the hanging rods 408 can be vertically adjusted by sliding. After reaching the appropriate position, the nut 505 is tightened in the opposite direction to make it fit against the side of the positioning frame. It works with the slider 502 to fix the position of the crossbar 503 and the hanging rod 408, adapting to the setting position of the handle groove 301 on the surface of different specifications of car roof 3, and meeting different roof mounting requirements.
