[0001] This utility model relates to the field of automobile production technology, and in particular to an automated welding production line for automobile bodies. Background Technology

[0002] Currently, robotics technology is widely used abroad, and robotic automated production lines have become the mainstream of automated equipment and the future direction of automated production lines. With the continuous development of the automotive manufacturing industry and the rising labor costs, the application of robots in this industry is already very common and will become the mainstream model in the future automotive manufacturing industry. Adopting robotic operations can improve the automation level of production equipment, thereby increasing labor productivity, while also improving product quality and enhancing the overall competitiveness of enterprises.

[0003] However, in the existing technology, although automated production lines can achieve diversified production of products to a certain extent through programming, it is difficult to adjust and modify the production line when the product model changes significantly or when a completely new product needs to be produced. This requires a lot of time and resources. Therefore, an automated welding production line for car bodies is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, when the product model changes significantly or a completely new product needs to be produced, the adjustment and transformation of the production line is difficult and requires a lot of time and resources. Therefore, an automated welding production line for car bodies is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated welding production line for car bodies, comprising a support frame and two sets of conveying devices. A connecting plate is fixedly installed at the lower end of the movable end of each of the two sets of conveying devices. An adjustment mechanism is provided at the lower end of each connecting plate. The adjustment mechanism includes a concave seat, two sets of irregularly shaped support plates, and a drive motor. A belt drive assembly is provided at one end of the concave seat. Four sets of guide rods are fixedly installed inside the concave seat. Two sets of movable plates are slidably installed on the outer wall of the four sets of guide rods. Four sets of threaded round seats are threaded through one end of each of the two sets of movable plates. Two sets of No. 2 threaded rods are rotatably installed through one end of the concave seat. A No. 1 threaded rod is rotatably installed through the other end of the concave seat. The upper ends of the two sets of irregularly shaped support plates are respectively fixed to the lower ends of the two sets of movable plates.

[0006] Preferably, a tension adjustment component is fixedly installed on the inner wall of the concave seat, and a portion of the tension adjustment component extends through one end of the concave seat to the interior of the belt drive assembly 25 and contacts the inner wall of the belt drive assembly.

[0007] Preferably, the outer walls of the two sets of first threaded rods are respectively threaded to the inner walls of two sets of threaded round seats, and the outer walls of the two sets of second threaded rods are respectively threaded to the inner walls of the other two sets of threaded round seats.

[0008] Preferably, a fixing frame is fixedly installed at one end of the concave seat, the outer walls of the two sets of No. 2 threaded rods are respectively fixed to the inner walls of the two pulleys inside the belt drive assembly, and the upper end of the concave seat is fixed to the lower end of the connecting plate.

[0009] Preferably, one end of the drive motor is fixed to one end of the fixed frame, and the output end of the drive motor passes through one end of the fixed frame and is fixed to the end of one set of No. 2 threaded rods.

[0010] Preferably, the upper ends of both sets of conveying devices are fixed to the inner top of the support frame, and a clamping mechanism is installed through one end of each set of irregular support plates.

[0011] Preferably, welding robotic arms are provided on both sides of the support frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, an adjustment mechanism is provided, and a drive motor provides power to the belt drive assembly. The belt drive assembly drives two sets of No. 2 threaded rods to rotate, and the two sets of No. 2 threaded rods provide power to two sets of No. 1 threaded rods. This causes the two sets of No. 2 threaded rods and the two sets of No. 1 threaded rods to rotate within the threads of four sets of threaded circular seats. The four sets of threaded circular seats then drive two sets of movable plates to move. Both sets of movable plates slide left and right on the outer walls of the four sets of guide rods. Simultaneously, the two sets of movable plates drive the four sets of clamping mechanisms to move left and right through two sets of irregularly shaped support plates. This allows for the adjustment of the positions of the four sets of clamping mechanisms, enabling the clamping of different models of car bodies and the movement of the car bodies. This avoids the difficulty of adjusting and modifying the production line and reduces the waste of a lot of time and resources. Attached Figure Description

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 4As shown, this utility model provides an automated welding production line for car bodies, including a support frame 1 and two sets of conveying devices 11. A connecting plate 12 is fixedly installed at the lower end of the movable end of each of the two sets of conveying devices 11. An adjusting mechanism 2 is provided at the lower end of the connecting plate 12. The adjusting mechanism 2 includes a concave seat 21, two sets of irregularly shaped support plates 22, and a drive motor 24. A belt drive assembly 25 is provided at one end of the concave seat 21. Four sets of guide rods 26 are fixedly installed inside the concave seat 21. Two sets of movable plates 27 are slidably installed on the outer wall of the four sets of guide rods 26. Four sets of threaded round seats 28 are threaded through one end of each of the two sets of movable plates 27. Two sets of No. 2 threaded rods 211 are rotatably installed through one end of the concave seat 21, and a No. 1 threaded rod 210 is rotatably installed through the other end of the concave seat 21. The upper ends of the two sets of irregularly shaped support plates 22 are respectively connected to the two sets of movable plates 26. The lower end of plate 27 is fixed. The outer walls of two sets of No. 1 threaded rods 210 are respectively threaded to the inner walls of two sets of threaded round seats 28. The outer walls of two sets of No. 2 threaded rods 211 are respectively threaded to the inner walls of the other two sets of threaded round seats 28. A fixing frame 23 is fixedly installed at one end of the concave seat 21. The outer walls of the two sets of No. 2 threaded rods 211 are respectively fixed to the inner walls of the two pulleys inside the belt drive assembly 25. The upper end of the concave seat 21 is fixed to the lower end of the connecting plate 12. One end of the drive motor 24 is fixed to one end of the fixing frame 23. The output end of the drive motor 24 passes through one end of the fixing frame 23 and is fixed to the end of one set of No. 2 threaded rods 211. A clamping mechanism 14 is installed through one end of each of the two sets of irregular support plates 22. The upper ends of the two sets of conveying devices 11 are fixed to the inner top of the support frame 1.

[0022] The specific settings and functions of this embodiment are described below. The drive motor 24 is started, and the drive motor 24 drives two sets of second-order threaded rods 211 to rotate via the belt transmission assembly 25. These two sets of second-order threaded rods 211 drive two sets of first-order threaded rods 210 to rotate. The two sets of second-order threaded rods 211 and the two sets of first-order threaded rods 210 rotate within the threads of the four sets of threaded circular seats 28. Because the two sets of movable plates 27 are limited by the four sets of guide rods 26, the four sets of threaded circular seats 28 can only rotate within the threads of the two sets of second-order threaded rods 211 and the two sets of first-order threaded rods 210. The outer wall of the first threaded rod 210 moves left and right, and at the same time, the four sets of threaded round seats 28 drive the two sets of movable plates 27 to move. The two sets of movable plates 27 slide left and right on the outer wall of the four sets of guide rods 26. At the same time, the two sets of movable plates 27 drive the four sets of clamping mechanisms 14 to move left and right through the two sets of irregular support plates 22. In this way, the position of the four sets of clamping mechanisms 14 can be adjusted, so that different models of car bodies can be clamped and the car bodies can be moved. This prevents the production line from being difficult to adjust and modify, and reduces a lot of time and resources wasted.

[0023] The mounting bracket 23 provides support for the drive motor 24, increasing its stability.

[0024] With the sliding cooperation of the two sets of movable plates 27 and the four sets of guide rods 26, when the two sets of movable plates 27 move, the two sets of movable plates 27 will slide on the outer wall of the four sets of guide rods 26, which can guide and support the two sets of movable plates 27 and improve the stability of the two sets of movable plates 27 when they move.

[0025] The symmetrical arrangement of the four clamping mechanisms 14 facilitates stable clamping of the vehicle body and prevents the vehicle body from shaking during movement.

[0026] Example 2: Figure 1 and Figure 2 As shown, a tension adjustment component 29 is fixedly installed on the inner wall of the concave seat 21. A part of the tension adjustment component 29 passes through one end of the concave seat 21 to the inside of the belt drive component 25 and contacts the inner wall of the belt drive component 25. Welding robot arms 13 are provided on both sides of the support frame 1.

[0027] The overall effect of this embodiment is that the tension adjustment component 29 can adjust the tension of the belt drive component 25, so that the belt drive component 25 can stably receive power from the drive motor 24.

[0028] Two sets of welding robotic arms 13 are symmetrically arranged, which can weld both sides of the car body, improving the welding efficiency of the car body.

[0029] The usage and working principle of this device are as follows: First, adjust the distance of the four clamping mechanisms 14 according to the vehicle model, and start the drive motor 24. The drive motor 24 drives the two sets of No. 2 threaded rods 211 to rotate through the belt transmission assembly 25. The two sets of No. 2 threaded rods 211 drive the two sets of No. 1 threaded rods 210 to rotate. The two sets of No. 2 threaded rods 211 and the two sets of No. 1 threaded rods 210 rotate inside the threads of the four sets of threaded round seats 28. The four sets of threaded round seats 28 drive the two sets of movable plates 27 to move. The two sets of movable plates 27 slide left and right on the outer wall of the four sets of guide rods 26. At the same time, the two sets of movable plates 27... Two sets of irregular support plates 22 drive four sets of clamping mechanisms 14 to move left and right, and the position of the four sets of clamping mechanisms 14 can be adjusted to clamp different models of car bodies. Then, the car body is clamped and fixed by the four sets of clamping mechanisms 14. Then, two sets of conveying devices 11 are operated synchronously. The conveying devices 11 drive the concave seat 21 to move through the connecting plate 12, and drive the car body to move through the entire adjustment mechanism 2 and the four sets of clamping mechanisms 14. The car body can be moved to the middle of the two sets of welding robot arms 13. Finally, the two sets of welding robot arms 13 are started and welded on the car body.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
