Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, and in particular to a clamping fixture for a gas storage tank. Background Technology

[0002] As a specialized component on semi-trailers, the air tank is mainly used to store gas to prevent the vehicle from being unable to start due to insufficient air pressure after parking. The current manufacturing process of air tanks involves welding two hemispherical end caps into a cylindrical body, and then welding the mounting lugs at both ends of the tank body and the air inlet and outlet connectors at the opening of the cylinder body.

[0003] During the welding process, the gas storage tank requires a clamping device to hold the tank body. The existing clamping device mainly consists of a bracket, a cylinder, and upper and lower clamping plates. During operation, the worker needs to move the tank body onto the bracket, and then activate the cylinder. The cylinder's driving action causes the upper clamping plate to descend, thereby clamping the tank body for welding. After welding is completed, the worker can then move the welded gas storage tank down to proceed to the next welding operation. During the welding process, the worker needs to constantly adjust the welding posture to weld the tank body completely, which is time-consuming, labor-intensive, and inefficient.

[0017] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0018] like Figures 1 to 3 As shown, a gas storage tank clamping fixture includes a base 1, on which a first bidirectional lead screw 2 is rotatably mounted. The two sides of the first bidirectional lead screw 2 are connected to mounting plates 3 via sliders. Material support components are respectively arranged opposite to each other on the two mounting plates 3. A bracket 4 is provided on one side of the base 1, and the top of the bracket 4 is connected to a pressing component via a cylinder 5.

[0019] One end of the first bidirectional lead screw 2 is fixedly connected to the output end of the first motor 6. The base 1 is provided with a slide rod 7, which is arranged parallel to the first bidirectional lead screw 2. The two mounting plates 3 are respectively movably arranged on the first bidirectional lead screw 2 and the slide rod 7, and can be adjusted according to the length of different gas storage tanks.

[0020] The material support assembly includes a material support roller 8, which is rotatably mounted at both ends of an arc-shaped bracket 9. The arc-shaped bracket 9 is rotatably mounted on a mounting base 10 via a connecting rod. The mounting base 10 is movable at both ends of a second bidirectional lead screw 11 via a slider. The second bidirectional lead screw 11 is horizontally mounted within a mounting plate 3. One end of the second bidirectional lead screw 11 is fixedly connected to the output end of a second motor 12. The mounting plate 3 is provided with a sliding groove 13, which is located above the second bidirectional lead screw 11. The mounting base 10 is movably mounted within the sliding groove 13. A bellows baffle 14 is provided between the sliding groove 13 and the mounting base 10. When the gas storage tank is placed between the material support assemblies on the two mounting plates 3, the second motor 12 drives the mounting base 10 to move via the second bidirectional lead screw 11, and the material support roller 8 on the mounting base 10 lifts the tank.

[0021] The pressing assembly includes a pressing roller 15, which is rotatably arranged on both sides of a mounting cover 16. The pressing roller 15 is arranged parallel to the supporting roller 8. A third motor 17 is installed inside the mounting cover 16. The output end of the third motor 17 is connected to the rotating shaft of the pressing roller 15 via a chain 18. The top of the mounting cover 16 is connected to a fixed base 20 via a rod 19. The fixed base 20 is connected to a cylinder 5. The rod 19 is movably arranged in the fixed base 20. A spring 21 and a pressure sensor 22 are installed inside the fixed base 20. Pressure sensor 22 is connected to cylinder 5. Cylinder 5 drives the pressure roller 15 on mounting cover 16 to descend, which, together with the material support roller 8, clamps the tank. After the pressure roller 15 contacts the tank, the insertion rod 19 moves into the fixed seat 20, compressing the spring 21 and then contacting the pressure sensor 22. After the pressure sensor 22 receives the signal, cylinder 5 stops extending to avoid over-clamping the tank and causing damage. During welding, the third motor 17 drives the pressure roller 15 to rotate through chain 18, causing the tank to rotate between the material support roller 8 and the pressure roller 15, which facilitates welding operations for the workers.

[0022] To further reduce the workload of staff, a mobile welding device can be installed on one side of the mounting plate 3 to automatically weld the tank.

[0023] In use, the distance between the two mounting plates 3 is adjusted according to the length of different gas tanks. The gas tank body is placed between the material support components on the two mounting plates 3. The second motor 12 drives the mounting base 10 to move through the second bidirectional lead screw 11. The material support roller 8 on the mounting base 10 lifts the tank body. The cylinder 5 drives the pressure roller 15 on the mounting cover 16 to descend, cooperating with the material support roller 8 to clamp the tank body. After the pressure roller 15 contacts the tank body, the insertion rod 19 moves into the fixed base 20, compressing the spring 21 and then contacting the pressure sensor 22. After the pressure sensor 22 receives the signal, the cylinder 5 stops extending to avoid excessive clamping of the tank body and damage to the tank body. During welding, the third motor 17 drives the pressure roller 15 to rotate through the chain 18, so that the tank body rotates between the material support roller 8 and the pressure roller 15, which facilitates the welding operation for the workers.
