Each set of connecting tubes has a common mounting plate at its lower end. An electric push rod is mounted at the lower end of the mounting plate. The electric push rod is fixed to the worktable. A suction cup is connected to the upper end of the connecting tube. A vacuum tube is connected to each connecting tube. Each suction cup is equipped with a nozzle at its lower end, and a spray pipe is connected to the nozzle. The spray pipe is fixed to the connecting pipe. The support structure includes a support block, the upper wall of which has a groove, and an installation block is slidably disposed in the groove. The installation block and the groove are connected by a spring, and a pressure plate is installed on the upper wall of the installation block.

[0004] Preferably, the upper wall of the worktable is provided with a sliding groove that matches the support block, the support block is slidably disposed in the sliding groove, and a hydraulic cylinder is installed on the support block, the hydraulic cylinder being installed in the sliding groove.

[0005] Preferably, the workbench is provided with a drain hole.

[0006] Preferably, a waterproof box is attached to the outside of the electric push rod, and the waterproof box is fixed to the workbench.

[0007] This utility model has the following beneficial effects: The utility model has a reasonable structure and novel design. When in use, the position of a pair of support structures is adjusted according to the model of the top cover. The position of the suction cup is adjusted by adjusting the electric push rod. The top cover is placed on the pressure plate. The pump body is started to evacuate the inside of the connecting pipe. Under the action of air pressure difference, the suction cup is attracted to the lower surface of the top cover to fix the top cover. Water enters the nozzle through the spray pipe and is sprayed onto the suction cup to cool it down and avoid heat conduction that could damage the suction cup. Attached Figure Description

Detailed Implementation

[0010] 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.

[0011] Please see Figure 1 , one A welding positioning device for automobile roof includes a worktable 1, a positioning structure on the worktable 1, and support structures on both sides of the positioning structure. The top cover is placed on the supporting structure and fixed by the positioning structure; The positioning structure includes multiple sets of fixing components horizontally set on the workbench 1. Each set of fixing components includes multiple longitudinally arranged connecting pipes 2. Each set of connecting pipes 2 has a common mounting plate 3 at its lower end. An electric push rod 4 is installed at the lower end of the mounting plate 3. The electric push rod 4 is fixed on the workbench 1. A suction cup 5 is connected to the upper end of the connecting pipe 2. A vacuum tube 6 is connected to each connecting pipe 2. The vacuum tube 6 is connected to the pump body for vacuuming. When fixing the top cover, start the pump body to evacuate the inside of the connecting pipe 2. Under the action of air pressure difference, the suction cup 5 is attracted to the lower surface of the top cover to fix the top cover. By starting the electric push rod 4, the connecting pipe 2 in the same group can be raised and lowered, which is convenient for use according to different models of top covers. Each suction cup 5 is equipped with a nozzle 7 at its lower end. A nozzle 8 is connected to the nozzle 7. The nozzle 8 is fixed to the connecting pipe 2 and is connected to the water source. Water enters the nozzle 7 through the spray pipe 8 and is sprayed onto the suction cup 5 through the nozzle 7 to cool the suction cup 5 and prevent heat conduction from damaging the suction cup 5.
