Description

Technical Field

[0001] This utility model belongs to the field of automotive processing technology, specifically an adjustable automotive welding lifting multi-angle support platform. Background Technology

[0002] Automotive welding is a core process in modern automobile manufacturing, involving complex processes, precise equipment operation, and a rigorous quality control system, covering all stages from body assembly to component connection. This technology directly affects the structural strength, safety performance, and overall quality of a vehicle. Automotive welding primarily employs various techniques. Resistance spot welding is the most commonly used technique, particularly suitable for most body assembly work, offering advantages such as high efficiency, low cost, and good overall integrity. Laser welding and laser brazing provide even higher precision and quality, mainly used for critical areas such as the roof and rear cover, characterized by a small heat-affected zone and high weld quality. Typically, the components to be welded are placed on top of a support platform before welding. However, existing support platforms often use clamping structures to hold and fix components, which are generally fixed to the platform and difficult to move. This makes it difficult to clamp components of different sizes, affecting the practicality of the support platform. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an adjustable multi-angle support platform for automotive welding lifting. It solves the problem that when using a clamping structure to clamp and fix parts, the clamping structure is generally fixed on the support platform and difficult to move, making it difficult for the clamping structure to clamp parts of different specifications, thus affecting the practicality of the support platform.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable multi-angle support platform for automobile welding lifting, comprising a support frame, electric telescopic rods installed on the top of both sides of the support frame, lifting plates provided on the top of the electric telescopic rods, a mounting frame rotatably connected between the two lifting plates via bearings, two electric push rods fixedly connected to both sides of the mounting frame, an adjustment seat provided at one end of each electric push rod passing through the mounting frame, the adjustment seat being slidably connected to the inner wall of the mounting frame, a mounting plate fixedly connected to one bottom side of the adjustment seat, two bidirectional threaded rods rotatably connected inside the adjustment seat via bearings, and the two bidirectional threaded rods being fixedly connected, one end of one of the bidirectional threaded rods being fixedly connected to a knob passing through the adjustment seat, pins installed at the bottom of both sides of the adjustment seat, the pins being inserted and fixedly connected to the knob, two movable seats symmetrically threaded through each of the bidirectional threaded rods, the movable seats being slidably connected to the inner wall of the adjustment seat, a connecting rod rotatably connected to the bottom of the movable seat via a pin, and the ends of the two connecting rods away from the movable seats being rotatably connected to the same clamping plate via a pin, the clamping plate corresponding to the position of the mounting plate.

[0005] As a further embodiment of this utility model: two limiting rods are fixedly connected to the side of the adjusting seat near the electric push rod, and the limiting rods are slidably connected through the inner wall of the mounting frame.

[0006] As a further embodiment of this utility model: the bottom of the lifting plate is fixedly connected to two linkage rods on both sides of the electric telescopic rod, and the linkage rods are slidably connected to the support frame.

[0007] As a further embodiment of this utility model: the mounting frame is fixedly connected to the lifting plate on both sides, and the lifting plate is fixedly connected to the fixing seat on both sides of the lifting gear. The fixing seat is slidably connected to the limiting tooth block, and the limiting tooth block corresponds to the position of the lifting gear.

[0008] As a further embodiment of this utility model: the bottom of the linkage gear is engaged with a toothed plate, a connecting block is fixedly connected to one side of the toothed plate, and a sliding groove is provided at the bottom of the lifting plate near the connecting block, and the inner wall of the sliding groove is slidably connected to the connecting block.

[0009] As a further embodiment of this utility model: an electric adjusting rod is fixedly connected to the top of the lifting plate near the toothed plate, and a linkage block is installed at one end of the electric adjusting rod, and the linkage block is fixedly connected to the toothed plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This adjustable automotive welding lifting multi-angle support platform, through the setting of electric push rods, adjusting seats, knobs, and bidirectional threaded rods, allows the electric push rods on both sides of the mounting frame to push the adjusting seats to move relative to each other. After the adjusting seats move the mounting plate to the appropriate position, the workpiece is placed on top of the mounting plate. Rotating the knob causes the bidirectional threaded rod to rotate, which in turn causes the movable seat to move relative to each other. The movable seat then pushes the clamping plate to move via the connecting rod. The clamping plate, in conjunction with the mounting plate, clamps and fixes the workpiece, enabling the clamping and fixing of workpieces of different specifications. This facilitates the welding processing of the workpieces and improves the practicality of the device.

[0012] 2. This adjustable automotive welding lifting multi-angle support platform, through the setting of linkage gears, limit gear blocks, and gear plates, pulls the limit gear blocks to move inside the fixed seat and disengage from the linkage gears. The electric adjustment rod drives the linkage block to move, causing the linkage block to drive the gear plate to rotate. The gear plate, through meshing with the linkage gear, drives the linkage gear to rotate, which in turn drives the mounting frame to rotate, allowing for angle adjustment of the workpiece within the mounting frame, facilitating welding processing of the workpiece at different angles.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: an adjustable multi-angle support platform for automobile welding lifting, including a support frame 1, electric telescopic rods 2 installed on the top of both sides of the support frame 1, a lifting plate 3 set on the top of the electric telescopic rods 2, and two linkage rods 14 fixedly connected to the bottom of the lifting plate 3 on both sides of the electric telescopic rods 2. The linkage rods 14 are slidably connected to the support frame 1 through the linkage rods 14. By setting the linkage rods 14, the electric telescopic rods 2 drive the lifting plate 3 to move, and at the same time, the lifting plate 3 drives the linkage rods 14 to slide inside the support frame 1, so that the support frame 1 limits the movement of the lifting plate 3 through the linkage rods 14, so that the lifting plate 3 can stably drive the mounting frame 4 to adjust the height.

[0019] A mounting frame 4 is rotatably connected between two lifting plates 3 via bearings. A linkage gear 15 is fixedly connected to both sides of the mounting frame 4 through the lifting plates 3. A fixed seat 16 is fixedly connected to both sides of the lifting plates 3 and the linkage gear 15. A limiting tooth block 17 is slidably connected inside the fixed seat 16. The limiting tooth block 17 is positioned corresponding to the linkage gear 15. By setting the limiting tooth block 17, the limiting tooth block 17 moves inside the fixed seat 16, so that the limiting tooth block 17 can be inserted into the linkage gear 15 to fix the linkage gear 15.

[0020] A toothed plate 18 meshes with the bottom of the linkage gear 15. A connecting block 19 is fixedly connected to one side of the toothed plate 18. A sliding groove 20 is opened at the bottom of the lifting plate 3 near the connecting block 19. The inner wall of the sliding groove 20 is slidably connected to the connecting block 19. By setting the toothed plate 18, when the toothed plate 18 moves, it drives the linkage gear 15 to rotate through meshing with the linkage gear 15, so that the linkage gear 15 can drive the mounting frame 4 to rotate, thereby adjusting the tilt angle of the mounting frame 4.

[0021] An electric adjusting rod 21 is fixedly connected to the top of the lifting plate 3 near the toothed plate 18. A linkage block 22 is installed at one end of the electric adjusting rod 21. The linkage block 22 is fixedly connected to the toothed plate 18. By setting the electric adjusting rod 21, the electric adjusting rod 21 drives the toothed plate 18 to move through the linkage block 22, so that the toothed plate 18 can drive the linkage gear 15 to rotate, thereby realizing the angle adjustment between the linkage gear 15 and the mounting frame 4.

[0022] Two electric push rods 5 are fixedly connected to both sides of the mounting frame 4. One end of the electric push rod 5 passes through the mounting frame 4 and is provided with an adjustment seat 6. Two limiting rods 13 are fixedly connected to the side of the adjustment seat 6 near the electric push rod 5. The limiting rods 13 are slidably connected to the inner wall of the mounting frame 4. By setting the limiting rods 13, when the electric push rod 5 pushes the adjustment seat 6 to move, the adjustment seat 6 drives the limiting rods 13 to slide inside the mounting frame 4, so that the mounting frame 4 limits the adjustment seat 6 through the limiting rods 13, making the movement of the adjustment seat 6 more stable.

[0023] The adjusting seat 6 is slidably connected to the inner wall of the mounting frame 4. A mounting plate 7 is fixedly connected to the bottom of one side of the adjusting seat 6. Two bidirectional threaded rods 9 are rotatably connected inside the adjusting seat 6 through bearings, and the two bidirectional threaded rods 9 are fixedly connected. One end of one of the bidirectional threaded rods 9 passes through the adjusting seat 6 and is fixedly connected to a knob 8. Pins 23 are installed on the bottom of both sides of the adjusting seat 6. The pins 23 are inserted and fixed to the knob 8. By setting the bidirectional threaded rods 9, the knob 8 drives the bidirectional threaded rods 9 to rotate, so that the bidirectional threaded rods 9 can drive the movable seat 10 to move relative to each other, thereby facilitating the movable seat 10 to drive the connecting rod 11 to move and adjust the position of the pressing plate 12.

[0024] Each bidirectional threaded rod 9 has two symmetrical through-threaded connections to two movable seats 10. The movable seats 10 are slidably connected to the inner wall of the adjusting seat 6. The bottom of the movable seat 10 is rotatably connected to a connecting rod 11 via a pin. The ends of the two connecting rods 11 away from the movable seats 10 are rotatably connected to the same clamping plate 12 via pins. The clamping plate 12 is positioned corresponding to the mounting plate 7. By setting the clamping plate 12, the bidirectional threaded rod 9 drives the movable seat 10 to move. The movable seat 10 drives the clamping plate 12 to move up and down via the connecting rod 11, so that the frame of the clamping plate 12 cooperates with the mounting plate 7 to clamp and fix workpieces of different specifications.

[0025] The working principle of this utility model is as follows:

[0026] Place the workpiece between the two adjusting seats 6, activate the electric push rod 5. The electric push rod 5 drives the adjusting seat 6 to move, causing the adjusting seat 6 to move the mounting plate 7 to the bottom of the workpiece. Place the workpiece on top of the mounting plate 7, move the pin 23 to release the insertion limit on the knob 8, and rotate the knob 8. The knob 8 drives the bidirectional threaded rod 9 to rotate, allowing the bidirectional threaded rod 9 to drive the movable seat 10 to move relative to it. The movable seat 10 pushes the clamping plate 12 down through the connecting rod 11. The clamping plate 12, together with the mounting plate 7, fixes the workpiece. Activate the electric extension... Telescopic rod 2, the electric telescopic rod 2 drives the mounting frame 4 through the lifting plate 3. After the mounting frame 4 is adjusted to a suitable height, the limiting tooth block 17 moves. The limiting tooth block 17 moves inside the fixed seat 16 to cancel the limitation on the linkage gear 15. The electric adjusting rod 21 drives the linkage block 22 to move, so that the linkage block 22 can drive the tooth plate 18 to move. The tooth plate 18 drives the linkage gear 15 to rotate, so that the linkage gear 15 drives the mounting frame 4 to rotate, thereby realizing the angle adjustment of the workpiece in the mounting frame 4, which facilitates welding of the workpiece at different angles.
