[0001] This utility model relates to the field of automotive production line installation technology, specifically to a precision welding gripping auxiliary device for automotive production line installation. Background Technology

[0002] Welding is one of the core processes in automobile production. In existing automobile production lines, welding gripping auxiliary equipment is usually used to lift the parts to be welded to the welding position. However, the existing welding gripping auxiliary equipment cannot adjust the angle of the lifted parts. During the installation process of automobile production lines, some parts often need to be manually adjusted when welding at specific angles. This not only reduces the welding accuracy of the production line, but also increases the labor intensity of the workers. Utility Model Content

[0003] The purpose of this invention is to solve the problems mentioned in the background art and to provide a precision welding gripping auxiliary device for automobile production line installation.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

A connecting plate is provided below the scissor lifting structure, and adjusting structures are provided on both sides of the connecting plate, with the adjusting structures on both sides arranged symmetrically and mirror-like. Gripping structures are provided on both sides below the adjusting structures. The adjusting structure further includes a support plate, an angle adjusting component, a telescopic component, and a limiting component.

[0006] The angle adjustment components are arranged on both sides of the connecting plate, a support plate is arranged below the angle adjustment components, telescopic components are arranged on both sides of the support plate, and a limit component is arranged on one side of the angle adjustment components.

[0007] Preferably, the angle adjustment assembly includes a support rod, a guide rod, a guide block, and a second hydraulic cylinder;

[0008] One end of each of the guide rods on both sides is fixedly connected to the support plate. The outer wall of the guide rod is slidably connected to the support rod.

The fixed end of the second hydraulic cylinder is fixedly connected to the connecting plate.

[0009] Preferably, a circular block is provided on one side of the guide block adjacent to the support rod. The radial dimension of the circular block is the same as the width dimension of the slide groove, and the axial length of the circular block is the same as the depth of the slide groove. The circular block can match the slide groove.

[0010] Preferably, the limiting component includes an arc-shaped rod, a limiting rod, an arc-shaped block, a third hydraulic cylinder, and a fixing rod;

[0011] One side of the arc-shaped rod is fixedly connected to the support rod, the lower arc surface of the arc-shaped rod abuts against the arc-shaped block, the end of the arc-shaped block away from the arc-shaped rod is set on the limiting rod, the inner wall of the limiting rod is sleeved with the fixing rod, the end of the fixing rod away from the limiting rod is fixedly connected to the connecting plate, the end of the fixing rod away from the connecting plate is fixedly connected to the fixed end of the third hydraulic cylinder, and the output end of the third hydraulic cylinder is fixedly connected to the limiting rod.

[0016] Preferably, the support plate has symmetrically mirrored gripping structures on both sides.

[0017] This utility model proposes a precision welding gripping auxiliary device for automotive production line installation. Its advantages are as follows: By controlling multiple first hydraulic cylinders simultaneously to move the support plate away from the connecting plate, the support plate drives the sliding rod to slide along the inner wall of the connecting rod, increasing the distance between the connecting plate and the support plate. Controlling the third hydraulic cylinder to move the limiting rod separates the arc-shaped block from the arc-shaped rod. When adjusting the angle of the support plate, controlling the second hydraulic cylinder to move the guide block, the circular block moves along the sliding groove while simultaneously driving the support rod to rotate along the connecting plate. The support rod, through the guide rod, drives the support plate to move circumferentially, thereby adjusting the welding angle of the components between the gripping components. After adjusting to a suitable angle, controlling the third hydraulic cylinder to move the arc-shaped block against the arc-shaped rod restricts the adjustment angle of the support plate, improving the stability of the support plate angle adjustment. This avoids the problem of manually adjusting the angle of some components when welding at specific angles during automotive production line installation, improving welding precision and reducing labor intensity.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] See attached document Figure 1-6 A precision welding gripping auxiliary device for automotive production line installation includes a scissor lift structure 1, a gripping structure 2, and an adjusting structure 3. A connecting plate 101 is located below the scissor lift structure 1. The scissor lift structure 1 is used to raise or lower the height of the parts to be welded. The end of the scissor lift structure 1 away from the connecting plate 101 is typically connected to a hoisting track inside the workshop for transporting the parts. The gripping structure 2 is used to clamp and grip the parts to be welded. Adjusting structures 3 are respectively arranged on both sides of the connecting plate 101, and the two adjusting structures 3 are symmetrically mirrored. Gripping structures 2 are respectively arranged on both sides below the adjusting structures 3. The adjusting structure 3 also includes a support plate 301 and an angle adjustment mechanism. The device includes a joint assembly, a telescopic assembly, and a limiting assembly. An angle adjustment assembly is located on both sides of the connecting plate 101. The angle adjustment assembly is used to adjust the angle of the support plate, thereby further adjusting the welding angle of the parts to be welded. A support plate 301 is located below the angle adjustment assembly. Telescopic assemblies are located on both sides of the support plate 301. The telescopic assemblies are used to adjust the height of the parts to be welded, ensuring sufficient space during the rotation of the support plate 301. After use, the telescopic assemblies can be retracted to reduce the space occupied by the equipment. The limiting assembly limits the welding angle of the parts after adjustment, ensuring the stability of the angle adjustment. A limiting assembly is located on one side of the angle adjustment assembly.

[0027] The angle adjustment assembly includes a support rod 303, a guide rod 302, a guide block 308, and a second hydraulic cylinder 307. One end of each guide rod 302 is fixedly connected to a support plate 301. The outer wall of the guide rod 302 is slidably connected to the support rod 303. The side of each support rod 303 adjacent to the support plate 301 is hinged to a connecting plate 101. A groove 3031 is provided in the middle of the support rod 303. A guide block 308 is provided on one side of the groove 3031. The side of the guide block 308 away from the support rod 303 is fixedly connected to the output end of the second hydraulic cylinder 307. The fixed end of the second hydraulic cylinder 307 is fixedly connected to the connecting plate 101. Figure 6 The lower end of the guide block 308 is in contact with the connecting plate 101 to ensure that the guide block 308 can slide in contact with the connecting plate 101. The second hydraulic cylinders 307 on both sides move synchronously through the control system. The second hydraulic cylinders 307 drive the guide block 308 to move, and the guide block 308 drives the round block 3081 to move. While the round block 3081 moves along the slide groove 3031, the round block 3081 drives the support rod 303 to rotate along the connecting plate 101. The support rod 303 drives the guide rod 302 to move circumferentially, and the guide rod 302 drives the support plate 301 to move circumferentially.

[0028] A circular block 3081 is provided on one side of the guide block 308 adjacent to the support rod 303. The radial dimension of the circular block 3081 is the same as the width dimension of the slide groove 3031, and the axial length of the circular block 3081 is the same as the depth of the slide groove 3031. The circular block 3081 can match the slide groove 3031.

[0029] The limiting assembly includes an arc-shaped rod 309, a limiting rod 310, an arc-shaped block 3101, a third hydraulic cylinder 311, and a fixing rod 312. One side of the arc-shaped rod 309 is fixedly connected to the support rod 303. The lower arc surface of the arc-shaped rod 309 abuts against the arc-shaped block 3101. The end of the arc-shaped block 3101 away from the arc-shaped rod 309 is mounted on the limiting rod 310. The inner wall of the limiting rod 310 is sleeved with the fixing rod 312. The end of the fixing rod 312 away from the limiting rod 310 is fixedly connected to the connecting plate 101. The end of the fixing rod 312 away from the connecting plate 101 is fixedly connected to the fixed end of the third hydraulic cylinder 311. The output end of the third hydraulic cylinder 311 is connected to the limiting rod 310. Before adjusting the angle of the support plate 301, the third hydraulic cylinder 311 is controlled to move the limiting rod 310. The limiting rod 310 moves the arc block 3101 away from the arc rod 309, causing the arc block 3101 to separate from the arc rod 309. When adjusting the angle of the support plate 301, the support rod 303 can drive the arc rod 309 to move circumferentially. After adjusting to a suitable angle, the third hydraulic cylinder 311 is controlled to move the arc block 3101 against the arc rod 309, thereby limiting the adjustment angle of the support plate 301 and improving the stability of the angle adjustment of the support plate 301. The third hydraulic cylinders 311 on both sides are synchronized through the control system.

[0030] The center of the arc of the arc rod 309 coincides with the hinge point between the support rod 303 and the connecting plate 101. The contact surfaces of the arc block 3101 and the arc rod 309 are respectively provided with teeth, and the teeth of the arc block 3101 mesh with the teeth of the arc rod 309, increasing the stability between the arc block 3101 and the arc rod 309.

[0031] The telescopic assembly includes a first hydraulic cylinder 306, a connecting rod 304, and a sliding rod 305. The ends of the connecting rods 304 on both sides are fixedly connected to the support rod 303, and the ends of the connecting rods 304 on both sides are fixedly connected to the support plate 301. One side of the connecting rod 304 is fixedly connected to the fixed end of the first hydraulic cylinder 306, and the output ends of the first hydraulic cylinders 306 on both sides are fixedly connected to the support rod 303. The support plate 301 has symmetrically mirrored gripping structures 2 on both sides. Multiple first hydraulic cylinders 306 on both sides move synchronously through a control system. Multiple first hydraulic cylinders 306 simultaneously drive the support plate 301 to move away from the connecting plate 301. The support plate 301 drives the sliding rod 305 to slide along the inner wall of the connecting rod 304. At the same time, the support rod 301 drives the guide rod 302 to slide along the inner wall of the support rod 303. By increasing the distance between the connecting plate 101 and the support plate 301, the movement space of the support plate 301 during circumferential movement is ensured, and the storage space required when the equipment is restricted after retrieval is reduced.

[0032] Specifically, during use, the gripping structure 2 grips the parts to be welded, the scissor-lift structure 1 lifts the parts, and the parts are moved to the welding position via the hoisting rails inside the workshop. Multiple first hydraulic cylinders 306 are controlled to simultaneously move the support plate 301 away from the connecting plate 301. The support plate 301 drives the sliding rod 305 to slide along the inner wall of the connecting rod 304, while the support rod 301 drives the guide rod 302 to slide along the inner wall of the support rod 303. By increasing the distance between the connecting plate 101 and the support plate 301, before adjusting the angle of the support plate 301, the third hydraulic cylinder 311 is controlled to move the limiting rod 310. The limiting rod 310 drives the arc block 3101 to move away from the arc rod 309, so that the arc block 3101 and... When the arc-shaped rod 309 separates, and the angle of the support plate 301 is adjusted, the second hydraulic cylinder 307 is controlled to drive the guide block 308 to move. The guide block 308 drives the circular block 3081 to move. While the circular block 3081 moves along the slide groove 3031, the circular block 3081 drives the support rod 303 to rotate along the connecting plate 101. The support rod 303 drives the guide rod 302 to move circumferentially. The guide rod 302 drives the support plate 301 to move circumferentially. The support rod 303 can drive the arc-shaped rod 309 to move circumferentially, thereby adjusting the welding angle of the parts between the gripping components 2. After adjusting to a suitable angle, the third hydraulic cylinder 311 is controlled to drive the arc-shaped block 3101 to abut against the arc-shaped rod 309, thereby limiting the adjustment angle of the support plate 301 and improving the stability of the angle adjustment of the support plate 301.
