[0002] The side panel is a crucial part of car body manufacturing, and its manufacturing quality directly affects the car's appearance and performance. The inner side panel is generally a ring-shaped structure, with the B-pillar on one side. The main function of the B-pillar is to provide protection in the event of a side collision, and it is desirable for the B-pillar to deform in a controlled manner during a side impact to protect passengers as much as possible, primarily for energy absorption. However, the inner side panel itself also needs to maintain a certain level of strength.

A second ball bearing sleeve is fixedly mounted at the center point of the top surface of the welding table, and a second ball bearing is movably mounted inside the second ball bearing sleeve. The second ball bearing and the first ball bearing are fixedly connected by a connecting rod, and the welding table is fixedly mounted on the upper end of the connecting rod. The connecting ball bearing moves freely in all directions, causing the welding table to move in all directions, facilitating the movement of the vehicle side panel on the welding table and improving the welding efficiency of the vehicle side panel.

[0004] When using the above technology, the following technical problems were found in the existing technology: In the automotive production line, the side panels of automobiles generally need to be transported using lifting devices. Due to the special structure of the side panels, traditional side panel lifting devices are complex and prone to instability during transportation, easily causing deformation of the side panels and affecting product quality. Therefore, an automotive side panel welding and conveying mechanism is designed to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A car side panel welding conveying mechanism includes a guide rail and further includes:

[0013] The synchronous belt assembly includes a drive pulley coaxially connected to a geared motor, a driven pulley coaxially connected to the first pulley, and a belt sleeved between the drive pulley and the driven pulley.

[0014] As a preferred embodiment of the automotive side panel welding conveying mechanism provided by this utility model, the plate frame includes a connecting end fixed to the bottom of the outer frame and a bearing surface integrally connected to the connecting end, and a plurality of the limiting members are provided on the bearing surface.

[0015] As a preferred embodiment of the automotive side panel welding conveying mechanism provided by this utility model, a set of hollows are opened on the bearing surface corresponding to the side panel, and multiple limiting members are respectively located at the edge of the hollows.

[0016] As a preferred embodiment of the automotive side panel welding conveying mechanism provided by this utility model, each of the multiple limiting members includes a second base fixed to the bearing surface by a support member, a first clamping end fixed to the second base, and a second clamping end that can elastically extend, retract, and rotate on the second base.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] like Figure 1 As shown, this type of automotive side panel welding conveying mechanism includes a guide rail 1, a traveling trolley 2, multiple limiting components 3, and a plate frame 4. The guide rail 1 is laid between two adjacent processing locations, and its length is the distance between the two processing locations. The traveling trolley 2 is slidably connected to the guide rail 1 and is used to carry and convey the automotive side panel 5 to be welded. The plate frame 4 is fixedly connected to the traveling trolley 2, providing a support platform for the automotive side panel 5 to be welded. The multiple limiting components 3 are evenly distributed and fixedly connected to the plate frame 4 to fix the automotive side panel 5 on the plate frame 4, thereby ensuring the stability and accuracy of the automotive side panel 5 during the conveying process.

[0037] like Figure 2 As shown, and for reference Figure 1 The traveling vehicle 2 includes a set of moving parts 21 that abut against the guide rail 1, an outer frame 22 connected between the set of moving parts 21, and a drive unit 23 disposed on the outer frame 22 and capable of driving the set of moving parts 21 to move synchronously on the guide rail 1.

[0038] The traveling vehicle 2 further includes a set of moving parts 21, an outer frame 22, and a drive unit 23. Specifically, the set of moving parts 21 all abut against the guide rail 1, ensuring that the traveling vehicle 2 slides smoothly and precisely on the guide rail 1. The design of the moving parts 21 takes into account the shape and size of the guide rail 1 to ensure optimal contact and support. The outer frame 22, as a structural member connecting the set of moving parts 21, not only provides sufficient strength and rigidity but also serves as the mounting base for other components such as the drive unit 23.

[0039] The drive unit 23 can drive a group of moving parts 21 to move synchronously. By controlling the drive unit 23, the vehicle 2 can be accurately positioned and moved quickly on the guide rail 1, thereby meeting the transportation needs of the vehicle side panel 5;

[0040] Each set of moving parts 21 includes a first base 211, and a first wheel 212 and a second wheel 213 respectively rotatably connected to both ends of the first base 211;

[0041] Based on the above, each set of moving parts 21 further includes a first base 211, a first wheel 212, and a second wheel 213. Specifically, the first base 211 serves as the main structure of the moving parts 21, bearing the first wheel 212 and the second wheel 213, and ensuring their relative positional relationship. That is, the first wheel 212 and the second wheel 213 are rotatably connected to both ends of the first base 211, and the first wheel 212 and the second wheel 213 can smoothly roll on the guide rail 1 by the driving member 23, for example, driving the first wheel 212. Furthermore, the set of moving parts 21 can not only slide smoothly and accurately on the guide rail 1;

[0042] The moving part 21 is preferably made of high-strength alloy material. This material not only has excellent load-bearing capacity and can effectively bear the weight of the car side panel 5, but also has good wear resistance and corrosion resistance, ensuring that the moving part 21 can maintain a good working condition during long-term use, and further ensuring the stability and safety of the conveying process.

[0043] The drive unit 23 further includes a geared motor 231 and a set of synchronous belts 232. Specifically, the geared motor 231 has a pair of output shafts that rotate in the same direction to provide power to the moving part 21. The synchronous belts 232 serve as a transmission medium, connecting the first wheel 212 and the output shafts of the geared motor 231 to ensure smooth and precise power transmission. When the geared motor 231 starts, its output shaft drives the synchronous belts 232 to rotate, thereby driving the first wheel 212 to rotate. Since both the first wheel 212 and the second wheel 213 are rotatably connected to the first base 211, and the rotation of the first wheel 212 drives the second wheel 213 to rotate synchronously, the entire moving part 21 can slide smoothly and precisely along the guide rail 1.

[0044] It should be noted that the geared motor 231 is a worm gear reducer, in which a pair of output shafts are connected to the worm wheel shaft from both sides of the worm wheel axis.

[0045] The synchronous belt assembly 232 further includes a drive pulley coaxially connected to the geared motor 231, a driven pulley coaxially connected to the first pulley 212, and a belt sleeved between the drive pulley and the driven pulley.

[0046] like Figure 3 As shown, and for reference Figure 1 The plate frame 4 includes a connecting end 41 fixed to the bottom of the outer frame 22, and a bearing surface 42 integrally connected to the connecting end 41. Multiple limiting members 3 are provided on the bearing surface 42.

[0047] The plate frame 4 further includes a connecting end 41 and a bearing surface 42; specifically, the connecting end 41 is fixed to the bottom of the outer frame 22 by welding or bolts to ensure the stability of the plate frame 4. The bearing surface 42 is designed as a planar structure for placing the car side panel 5 to be welded through multiple limiting members 3, and the bearing surface 42 and the limiting members 3 ensure that the car side panel 5 will not shift or shake during transportation.

[0048] A set of openings 43 are provided on the bearing surface 42; specifically, the design of the openings 43 is intended to reduce the overall weight of the frame 4, while facilitating observation and operation by the operator during welding of the car side panel 5. These openings 43 can also effectively dissipate heat, preventing the bearing surface 42 from deforming due to heat during prolonged welding. Multiple limiting members 3 are distributed along the edges of the openings 43, which not only serve to fix the car side panel 5, but also further enhance the structural strength of the frame 4 through their positional arrangement.

[0049] like Figure 4 As shown, and for reference Figure 1 Each of the multiple limiting members 3 further includes a support member 31, a second base 32, a first clamping end 33, and a second clamping end 34. Specifically, the support member 31 has an L-shaped structure, with one end fixedly connected to the bearing surface 42 by bolts or welding, and the other end connected to the second base 32, providing stable support for the second base 32. The second base 32, as a connecting member, not only supports the fixing of the first clamping end 33, but also allows the second clamping end 34 to flexibly extend, retract, and rotate.

[0050] The first clamping end 33 is fixed to one end of the second base 32. Its shape and size are designed according to the contour of the car side panel 5 to ensure a tight fit and provide stable clamping force. The second clamping end 34 is connected to the second base 32 through an elastic element (described below), allowing it to adjust the clamping force according to the thickness of the car side panel 5. Its rotational function allows for fine-tuning during clamping, ensuring that the car side panel 5 is firmly and evenly clamped. This design not only improves the adaptability of the conveying mechanism but also greatly simplifies the operation process and increases work efficiency.

[0051] like Figure 5 As shown, and for reference Figure 4 The second base 32 is a cavity 321; the limiting member 3 further includes a telescopic rod 36 and a tension spring 37; specifically, the telescopic rod 36 is located inside the cavity 321, one end of which is connected to the second clamping end 34 via a rotating shaft 35, and the other end is connected to the tension spring 37. One end of the tension spring 37 is fixed to the inner wall of the cavity 321, and the other end is connected to the telescopic rod 36. When the second clamping end 34 needs to adjust the clamping force or position, the telescopic rod 36 will extend and retract under the elastic force of the tension spring 37, providing necessary support and adjustment for the second clamping end 34, thereby expanding or shrinking the space formed between the first clamping end 33 and the second clamping end 34, so as to clamp different parts of the car side panel 5;

[0052] Both the first clamping end 33 and the second clamping end 34 include grippers 331 and a spacer 332 fixed to the grippers 331. The second clamping end 34 also includes a handle 341 fixed to the grippers 331. Through the handle 341, the operator can easily and manually adjust the position and force of the second clamping end 34 without the need for tools, further simplifying the operation process. Furthermore, the grippers 331 are made of high-strength material, ensuring clamping stability and durability. The spacer 332 is made of rubber, serving to isolate and protect the vehicle side panel 5, preventing unnecessary contact damage to the vehicle side panel 5 during transport.

[0053] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
