Description

Technical Field

[0001] This utility model relates to the field of automotive roof processing technology, specifically a positioning gripper for automotive roof processing. Background Technology

[0002] After prolonged use, car roof materials may age due to factors such as UV exposure, temperature changes, and humidity, leading to a decline in material performance and issues like fading, scratches, and peeling of the paint. Repairing a car roof requires removing the existing paint and repainting, followed by sanding and other finishing processes. Some existing car repair workshops use two independent support frames to hold the roof in place, secured with multiple clamps. However, some clamps are quite large, obstructing the roof's outer surface and requiring adjustments to ensure adequate processing, making the process inconvenient. While placing the repainted roof in sunlight can help the paint dry faster, the independent support frames make moving the secured roof difficult, increasing the risk of loosening during transport.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-5In this embodiment of the utility model, a positioning gripper for processing car roofs includes a movable frame 10, two control frames 102 fixedly connected between the tops of the two movable frames 10, a base 11 slidably connected to the top of the control frame 102, a sponge pad 12 slidably connected to the top of each of the two bases 11, a limiting band 13 movably latched to the bottom of the sponge pad 12, a hook 132 fixedly connected to one end of the limiting band 13, a limiting module 14 disposed at the bottom of the limiting band 13, the limiting module 14 being used to limit adjacent limiting bands 13, and a control module 15 disposed at the top of the base 11, the control module 15 being used to adjust the height of the sponge pad 12.

[0033] Specifically, multiple limiting straps 13 are movably engaged at the bottom of the sponge pad 12. By adjusting the spacing and height of the two sponge pads 12, the car roof is stably supported. The hooks 132 are engaged with both ends of the car roof, and the limiting straps 13 are pulled to quickly limit the hooks 132, thereby quickly positioning the car roof at the four corners. This facilitates quick and stable positioning of different models of car roofs. Furthermore, the hooks 132 do not obstruct the outer wall of the car roof, making processing more convenient. The entire device is movable, making it easy to transfer the car roof indoors and outdoors, and convenient to use.

[0034] Example 1

[0035] like Figure 4-5 As shown, in this embodiment, a rectangular plate 121 is fixedly connected to the bottom of the sponge pad 12, a ratchet rack 131 is fixedly connected to the bottom of the limiting band 13, a fixing screw 134 is screwed onto the outer wall of the hook 132, an L-shaped plate 133 for limiting the fixing screw 134 is fixedly connected to the outer wall of the hook 132, the limiting module 14 includes a plug rod 145, the plug rod 145 is slidably connected to the bottom of the rectangular plate 121, a spring 146 is fixedly connected between the plug rod 145 and the rectangular plate 121, the positioning frame 141 is fixedly connected to the bottom of the rectangular plate 121, a card seat 142 is slidably connected to the bottom of the positioning frame 141, the card seat 142 can be movably engaged with the ratchet rack 131, the spring 143 is fixedly connected between the card seat 142 and the positioning frame 141, both ends of the pull rod 144 are rotatably connected to the adjacent card seat 142, and the plug rod 145 can pass through the pull rod 144 and be movably engaged with it.

[0036] In this embodiment, the rectangular plate 121 facilitates the connection between the rectangular frame 157 and the rectangular plate 121. After the hook 132 is engaged at both ends of the car roof, the rotating fixing screw 134 is brought into contact with the outside of the car roof, thereby reinforcing the connection between the hook 132 and the car roof. The L-shaped plate 133 prevents the fixing screw 134 from separating from the hook 132 and being lost. The spring 143 drives the card seat 142 to move upward and reset. The card seat 142 limits the ratchet 131, allowing the limiting band 13 to move unidirectionally inside the positioning frame 141. After pulling the limiting band 13 causes the hook 132 to engage with one end of the car roof, the card seat 142 prevents the ratchet 131 from moving in the opposite direction and loosening itself, thereby quickly limiting the limiting band 13. The four hooks 132 are located at the four corners of the car roof for stable limiting.

[0037] like Figure 1-2 As shown, in this embodiment, a bidirectional lead screw 103 is rotatably connected inside the control frame 102. The bidirectional lead screw 103 passes through the base 11 and is screwed to it. One end of the bidirectional lead screw 103 is fixedly connected to a turntable 104. Multiple rollers 111 are rotatably connected to the bottom of the base 11. Two self-locking casters 101 are symmetrically fixed to the bottom of the movable frame 10.

[0038] In practice, rotating the turntable 104 drives the bidirectional lead screw 103 to rotate, thereby synchronously controlling the two bases 11 and adjusting the distance between the two sponge pads 12 to adapt to different car roof lengths. This allows the two sponge pads 12 to support the car roof in a more suitable position. The self-locking casters 101 make the overall movement of the equipment more convenient, and the self-locking casters 101 can be adjusted to lock themselves, making the equipment more stable when processing car roofs.

[0039] Example 2

[0040] Based on Example 1, in order to adjust the height of the sponge pad 12 to adapt to the curvature of different car cover models, the support is made more stable.

[0041] like Figure 1-3As shown, in this embodiment, the control module 15 includes a rectangular frame 157, which is fixedly connected to the top of the base 11. A support rod 151 is slidably connected inside the rectangular frame 157. The top end of the support rod 151 is fixedly connected to an adjacent rectangular plate 121. Multiple slots 152 are equidistantly provided on one side of the support rod 151. A docking plate 153 is provided on one side of the rectangular frame 157. The docking plate 153 can penetrate the rectangular frame 157 and be movably engaged with the adjacent slots 152. Two limiting rods 154 are fixedly connected to one side of the docking plate 153. The limiting rods 154 are slidably connected to the rectangular frame 157. Multiple springs 155 are fixedly connected between the docking plate 153 and the rectangular frame 157. A pull rod 156 is fixedly connected between the two docking plates 153.

[0042] In specific implementation, the rectangular frame 157 limits the support rod 151, thereby achieving vertical sliding limit of the sponge pad 12. This allows the support rod 151 to drive the sponge pad 12 to move vertically and adjust its height. Since the car roof has a certain curvature, adjusting the height of the sponge pad 12 allows the two sponge pads 12 to support and limit the car roof in a more suitable position, making the processing of the car roof more stable. Pulling the second pull rod 156 can simultaneously pull the two docking plates 153 out of the slot 152, stretching the multiple third springs 155. At this time, the sponge pad 12 can be moved up and down to adjust its height. After adjustment, the second pull rod 156 is released. Under the reset drive of the multiple third springs 155, the docking plate 153 moves and is inserted into the adjacent slot 152, thereby simultaneously limiting the two support rods 151 and quickly limiting the height of the sponge pad 12.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
