[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] This utility model provides a self-locking welding clamping platform for chassis pneumatic levers, such as Figures 1 to 4As shown, it includes: a base 1 and a positioning assembly for supporting the chassis to be welded. The positioning assembly includes positioning component 2, positioning component 3, cylinder 4, lever cylinder 5, positioning block 6, connecting component 7, and slider 8. Positioning component 2 is connected to the base 1, and there are two positioning components 2, located at the top of both ends of the base 1. Positioning component 3 is connected to the base 1, and there are four positioning components 3, located on both sides of the top of the base 1. Positioning component 2 and positioning component 3 can be positioning plates. Cylinder 4 is set between positioning component 2 and positioning component 3. The movable end is driven and connected to the lever cylinder 5. The positioning block 6 is movably set on the base 1. The connecting piece 7 can be an L-shaped plate. One end of the connecting piece 7 is movably set inside the lever cylinder 5 and connected to the positioning block 6. The slider 8 is T-shaped and connected to the positioning block 6. The outer surface of the slider 8 is slidably set on the base 1. Under the action of the cylinder 4, the positioning block 6 is driven to move in the horizontal direction. There are two cylinders 4 on the positioning piece 2. The cylinders 4 and the lever cylinder 5 are set one-to-one. The base 1 is provided with a slide groove 13, and the slider 8 is slidably set in the slide groove 13.

[0024] The positioning components can be used to press and fix the chassis, preventing it from moving horizontally and improving its stability. It can also meet the clamping requirements of chassis of different sizes, shorten clamping time and reduce processing costs, thereby effectively improving production efficiency.

[0025] In use, first place the chassis to be welded on the top of the base 1. Then, activate the cylinders 4 on the two positioning components 2. The moving end of the cylinder 4 drives the lever cylinder 5 to move. The movement of the lever cylinder 5 drives the positioning block 6 to move synchronously. The movement of the positioning block 6 drives the connecting piece 7 to move synchronously. The movement of the positioning block 6 drives the slider 8 to slide synchronously inside the slide groove 13. As the positioning block 6 moves, one end of the positioning block 6 will contact the outer surface of the chassis. When both positioning blocks 6 contact the outer surface of the chassis and press and fix the chassis, activate the lever cylinder 5. The moving end of the lever cylinder 5 will rotate downward and contact the connecting piece 7, pressing and fixing the connecting piece 7. Then, activate the cylinders 4 on the four positioning components 3. The moving end of the cylinder 4 drives the lever cylinder 5 to move. The movement of the lever cylinder 5 will contact the outer surface of the chassis and press and fix the chassis. At this time, the positioning operation of the chassis is completed.

[0026] Specifically, positioning components 2 are fixedly connected to the top of both ends of the base 1. Two cylinders 4 are fixedly connected to the outer surface of the positioning component 2. A lever cylinder 5 is fixedly connected to the movable end of the cylinder 4. A slider 8 is fixedly connected to the bottom of the positioning block 6. The outer surface of the slider 8 is slidably disposed inside the base 1. Connecting components 7 are fixedly connected to the top of both ends of the positioning block 6. The outer surface of the connecting component 7 is movably disposed inside the lever cylinder 5.

[0027] In order to clamp the chassis, such as Figures 1 to 4As shown, it also includes a clamping assembly, which includes a rotary cylinder 9, a swing arm 10, a threaded component 11, and a pressing component 12. The rotary cylinder 9 is connected to the base 1, and the movable end of the rotary cylinder 9 is driven to connect to the swing arm 10. The swing arm 10 is located above the rotary cylinder 9. The threaded component 11 is connected to the swing arm 10, and the pressing component 12 is connected to the threaded component 11. Under the action of the threaded component 11, the pressing component 12 is driven to move in the vertical direction. The threaded component 11 can be a threaded rod. Four rotary cylinders 9 are provided on the base 1. The pressing component 12 can be a pressing block. The swing arm 10 is arranged in a one-to-one correspondence with the rotary cylinder 9, and the pressing component 12 is located below the swing arm 10.

[0028] The clamping components effectively clamp the chassis, preventing it from moving vertically and thus improving its stability, which in turn enhances the reliability of the welding clamping platform.

[0029] In use, the four rotary cylinders 9 are activated. The movable end of the rotary cylinder 9 drives the swing arm 10 to rotate 180°. The rotation of the swing arm 10 drives the threaded part 11 and the extrusion part 12 to rotate 180° synchronously, so that the extrusion part 12 is located above the chassis. Then, the threaded part 11 is rotated, so that the threaded part 11 moves downward along the inside of the swing arm 10. The movement of the threaded part 11 drives the extrusion part 12 to move synchronously. As the extrusion part 12 moves, it will contact the outer surface of the chassis and form a compression fixation on the chassis.

[0030] Specifically, two positioning components 3 are fixedly connected to both sides of the top of the base 1. A cylinder 4 is fixedly connected to the outer surface of the positioning component 3. A lever cylinder 5 is fixedly connected to the movable end of the cylinder 4. A rotary cylinder 9 is fixedly connected to the top of the base 1 at the side position of the lever cylinder 5. A swing arm 10 is fixedly connected to the movable end of the rotary cylinder 9. A threaded component 11 is threaded to one end of the swing arm 10. A pressing component 12 is fixedly connected to the bottom end of the threaded component 11.

[0031] Working Principle: In actual use, the chassis to be welded is first placed on top of the base 1. Then, the cylinders 4 on the two positioning components 2 are activated. The moving end of the cylinder 4 drives the lever cylinder 5 to move. The movement of the lever cylinder 5 drives the positioning block 6 to move synchronously. The movement of the positioning block 6 drives the connecting component 7 to move synchronously. The movement of the positioning block 6 drives the slider 8 to slide synchronously inside the slide groove 13. As the positioning block 6 moves, one end of the positioning block 6 will contact the outer surface of the chassis. When both positioning blocks 6 contact the outer surface of the chassis and press and fix the chassis, the lever cylinder 5 is activated. The movable end of the lever cylinder 5 rotates downward and contacts the connector 7, pressing and fixing the connector 7. Then, the cylinders 4 on the four positioning parts 3 are activated. The movable end of the cylinder 4 drives the lever cylinder 5 to move. The movement of the lever cylinder 5 contacts the outer surface of the chassis and presses and fixes the chassis. At this time, the positioning operation of the chassis is completed, which can press and fix the chassis to prevent the chassis from moving in the horizontal direction, improve the stability of the chassis, and meet the clamping requirements of chassis of different sizes, shorten the clamping time and reduce the processing cost, thereby effectively improving the production efficiency.

[0032] Then, the four rotary cylinders 9 are activated. The moving end of the rotary cylinder 9 drives the swing arm 10 to rotate 180°. The rotation of the swing arm 10 drives the threaded part 11 and the extrusion part 12 to rotate 180° synchronously, so that the extrusion part 12 is located above the chassis. Then, the threaded part 11 is rotated, so that the threaded part 11 moves downward along the inside of the swing arm 10. The movement of the threaded part 11 drives the extrusion part 12 to move synchronously. As the extrusion part 12 moves, it will contact the outer surface of the chassis and form a compression fixation on the chassis. This can effectively perform a pressing operation on the chassis, prevent the chassis from moving in the vertical direction, thereby improving the stability of the chassis and thus improving the reliability of the welding clamping platform.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
