Description

Technical Field

[0001] This utility model relates to the field of laser welding technology for automobile roofs, specifically to a laser welding device for automobile roofs. Background Technology

[0002] A car roof is a plate-shaped part installed on the top of a car. During the manufacturing process of a car roof, a laser welding robot is used to weld it. The laser welding robot uses a semiconductor laser as the welding heat source to perform the welding work.

[0003] Chinese patent CN214079761U proposes a laser welding robot. Although an electric slide rail is provided on the front side of the laser welding robot body to drive the workpiece to move back and forth, the worktable of this laser welding robot is inconvenient for supporting and positioning the workpiece. There is an urgent need for a laser welding equipment for automobile roofs to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, a laser welding equipment for automobile roofs is disclosed, which includes a worktable, a laser welding device disposed on the upper surface of the worktable, a groove formed on the upper surface of the worktable, a support seat disposed at the center of the groove, and an arched structure on the upper surface of the support seat. The support base is symmetrically provided with clamping structures on the left and right sides. Each clamping structure includes clamping plates. A first mounting rod is installed on the opposite side of the clamping plates. Each first mounting rod is slidably sleeved with a sleeve. The first mounting rod and the sleeve are connected by a spring. The clamping plate has a segmented structure, with an arc-shaped upper end and a vertical lower end.

[0005] Preferably, mounting blocks are slidably inserted into the left and right ends of the groove, the mounting blocks are connected to the worktable by bolts, and the sleeve is fixed inside the mounting blocks.

[0006] Preferably, a plurality of rollers are rotatably mounted on the side surface of the clamping plate.

[0007] Preferably, a second mounting rod is mounted on the roller, the first mounting rod slides through the clamping plate, a connecting plate is mounted on the first mounting rod, a first electric push rod is mounted on the connecting plate, and the electric push rod is mounted on the clamping plate.

[0008] Preferably, a second electric push rod is installed at both the left and right ends of the groove, and a top plate is installed on the second electric push rod.

[0009] This utility model has the following beneficial effects: The structure is reasonable and the design is novel. In use, the top cover is placed on the support base. As the top cover descends, both sides of the top cover contact the clamping plates. As the top cover gradually descends, the clamping plates move to both sides, and the springs compress the plates. The spring's reaction force firmly clamps the clamping plates onto both sides of the top cover, fixing it in place. After the top cover is clamped by the clamping plates, the second electric push rod is activated, moving the top plate so that it rests against the inner wall of the top cover, which assists in clamping and supports the top cover, preventing it from bending under the pressure of the clamping plates. The first electric push rod can move the connecting plate, which in turn moves the first mounting rod, which in turn moves the roller. After the clamping plates clamp the top cover, moving the roller allows it to press against the curved surface of the top cover, fixing it in place. When the spring force gradually decreases with prolonged use and loses its effectiveness, the mounting block can be disassembled to facilitate replacement of the clamping structure and ensure the clamping effect.

Detailed Implementation

[0012] 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.

[0013] Please see Figure 1-2 A laser welding equipment for automobile roof includes a worktable 1, a laser welding device 15 is provided on the upper surface of the worktable 1, including a robotic arm and a welding device installed on the robotic arm. The laser welding device 15 is a device known to those skilled in the art, and its specific structure and working principle are not described in detail here. A groove 2 is provided on the upper surface of the worktable 1, and a support seat 3 is provided at the center of the groove 2. The upper surface of the support seat 3 has an arched structure, which facilitates fitting the curved surface of the roof. The support base 3 is symmetrically provided with clamping structures on the left and right sides. The clamping structures include clamping plates 4. The clamping plates 4 are segmented structures. The upper end of the clamping plates 4 is an arc-shaped segment, and the lower end of the clamping plates 4 is a vertical segment. The clamping plates 4 are mounted with first mounting rods 5 on their far sides. The first mounting rods 5 are all slidably sleeved with sleeves 6. The first mounting rods 5 and sleeves 6 are connected by springs 7. Place the top cover on the support base 3. As the top cover descends, the two sides of the top cover come into contact with the clamping plates 4. As the top cover gradually descends, the clamping plates 4 move to both sides. The spring 7 compresses the top cover, and the reaction force of the spring 7 clamps the clamping plates 4 firmly on both sides of the top cover, thus fixing the top cover. Mounting blocks 8 are slidably inserted into the left and right ends of the groove 2. The mounting blocks 8 are connected to the workbench 1 by bolts, and the sleeve 6 is fixed inside the mounting blocks 8. When the elasticity of spring 7 gradually decreases after long-term use, it can no longer provide an effective clamping effect. The mounting block 8 can be disassembled to facilitate the replacement of the clamping structure and ensure the clamping effect. Multiple rollers 9 are rotatably mounted on the side surface of the clamping plate 4. The rollers 9 can reduce the friction between the side of the top cover and the clamping plate 4, and prevent the surface of the top cover from being worn. A second mounting rod 10 is installed on the roller 9. The first mounting rod 5 slides through the clamping plate 4. A connecting plate 11 is installed on the first mounting rod 5. A first electric push rod 12 is installed on the connecting plate 11. The first electric push rod 12 is installed on the clamping plate 4. The first electric push rod 12 can drive the connecting plate 11 to move, thereby driving the first mounting rod 5 to move, and then driving the roller 9 to move. After the clamping plate 4 clamps the top cover, by moving the roller 9, the roller 9 is made to stick to the arc surface of the top cover, which can play a role in pressing down the top cover and fixing the top cover. A second electric push rod 13 is installed at both ends of the groove 2, and a top plate 14 is installed on the second electric push rod 13; After the top cover is clamped by the clamping plate 4, the second electric push rod 13 is activated to move the top plate 14, so that the top plate 14 abuts against the inner wall of the top cover, which can play an auxiliary clamping role and can also support the top cover to prevent the top cover from being bent by the clamping plate 4.

[0014] Example: In use, the top cover is placed on the support base 3. As the top cover descends, both sides of the top cover contact the clamping plates 4. As the top cover gradually descends, the clamping plates 4 move to both sides, and are compressed by the spring 7. The reaction force of the spring 7 firmly clamps the clamping plates 4 on both sides of the top cover, fixing the top cover in place. After the top cover is clamped by the clamping plates 4, the second electric push rod 13 is activated, driving the top plate 14 to move, so that the top plate 14 abuts against the inner wall of the top cover. This can play an auxiliary clamping role and also support the top cover to prevent it from tipping over. The cover is bent by the clamping plate 4. The first electric push rod 12 can drive the connecting plate 11 to move, thereby driving the first mounting rod 5 to move, and then driving the roller 9 to move. After the clamping plate 4 clamps the top cover, by moving the roller 9, the roller 9 is made to stick to the arc surface of the top cover, which can play a downward pressing role on the top cover and fix the top cover. When the elasticity of the spring 7 gradually decreases after long-term use, it can no longer play an effective clamping role. The mounting block 8 can be disassembled to facilitate the replacement of the clamping structure and ensure the clamping effect.
