Description

Technical Field

[0001] This utility model relates to the field of automobile production and processing technology, and specifically to a clamping mechanism for a spare tire compartment welding conveying device. Background Technology

[0002] The spare tire compartment is an integral part of a car's interior. It's typically located inside the trunk and stores the spare tire and other vehicle tools for easy access when needed. While the design and location of the spare tire compartment vary depending on the car model, most modern cars store the spare tire in the trunk. This maximizes its protection from external elements and ensures its durability. Welding is a crucial process in the production of the spare tire compartment. This includes welding the left and right rear reinforcing side beam assemblies, applying sealant, and placing the spare tire panel in a fixture while welding it to the left and right rear reinforcing side beam assemblies. This process requires the use of welding conveyor equipment.

[0003] A search revealed an ultrasonic welding machine for automotive interior trim in application document CN218396416U. This machine places the interior trim parts to be welded within a limiting member on a chain-plate conveyor mechanism, which then transports them directly below the welding mechanism for welding. After welding, the parts are transported to a lower processing unit by the same mechanism. This reduces the standby time of the welding mechanism and improves welding efficiency. Two symmetrical clamping components secure the interior trim parts below the welding mechanism, thereby increasing welding stability.

[0004] However, there are still some defects and shortcomings that need to be optimized. Specifically, although the ultrasonic welding machine for automotive interiors meets the welding and transfer operations of most automotive interiors, the clamping components are not compatible with the shape of the spare tire compartment, making it difficult to clamp effectively, which directly affects its stability during the welding process. Therefore, it is necessary to design a clamping mechanism for the spare tire compartment welding transfer equipment to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping mechanism for a spare tire compartment welding conveying device. The spare tire compartment welding workpiece table and the main body of the clamping mechanism are designed to match the shape and structure of the spare tire compartment, making it easy to perform effective clamping and thus ensuring its stability during the welding process, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clamping mechanism for a spare tire compartment welding conveying device includes a spare tire compartment welding workpiece table for welding conveying and a clamping mechanism body. The clamping mechanism body is composed of a first reinforcing plate clamp and a second reinforcing plate clamp arranged in parallel. A spare tire panel locator is provided between the first and second reinforcing plate clamps. Both the first and second reinforcing plate clamps include two sets of U-shaped clamps symmetrically distributed on both sides of the spare tire compartment welding workpiece table. The inside of the U-shaped clamps is equipped with clamping plates that are movably installed by telescopic cylinders through reinforcing plates. The side of the U-shaped clamp away from the spare tire compartment welding workpiece table is fixedly connected to the inner wall of the welding equipment mounting frame through a mounting seat.

[0008] As a preferred embodiment of this utility model, the bottom surface of the inner wall of the U-shaped clamp and the bottom surface of the clamping plate are both provided with clamping teeth. A limiting slide is fixedly installed at one end of the clamping plate near the side of the inner wall of the U-shaped clamp. A limiting groove adapted to the limiting slide is opened on the side of the inner wall of the U-shaped clamp, and the limiting slide and the limiting groove are slidably connected.

[0009] As a preferred embodiment of this utility model, the spare tire panel locator includes an I-shaped mounting frame, a telescopic cylinder for the spare tire panel, a positioning base, and guide members. The four corners of the I-shaped mounting frame are fixedly connected to adjacent U-shaped clamps. The bottom of the I-shaped mounting frame is movably mounted with a positioning base via the telescopic cylinder for the spare tire panel. Guide members are movably mounted on both sides of the top surface of the positioning base and the bottom surface of the I-shaped mounting frame, near the telescopic cylinder for the spare tire panel.

[0010] As a preferred embodiment of this utility model, the spare tire compartment welding workpiece table includes a spare tire panel table, a right rear longitudinal beam reinforcing plate table, and a left rear longitudinal beam reinforcing plate table. The spare tire panel table is located on the top surface of the chain conveyor belt, and the right rear longitudinal beam reinforcing plate table and the left rear longitudinal beam reinforcing plate table are respectively fixedly installed at the center of both sides of the spare tire panel table.

[0011] As a preferred embodiment of this utility model, positioning pins are fixedly installed on the top surfaces of both the right rear longitudinal beam reinforcing plate platform and the left rear longitudinal beam reinforcing plate platform, and the thickness of both the right rear longitudinal beam reinforcing plate platform and the left rear longitudinal beam reinforcing plate platform is less than the thickness of the spare tire panel platform.

[0012] As a preferred embodiment of this utility model, the right rear longitudinal beam reinforcing plate platform and the left rear longitudinal beam reinforcing plate platform respectively penetrate the interior of the adjacent U-shaped clamps and are located at the bottom of the clamps.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the spare tire compartment welding workpiece stage and clamping mechanism are designed specifically for the spare tire compartment's shape and structure, ensuring a high degree of compatibility with the spare tire compartment's shape and facilitating effective clamping. This guarantees the spare tire compartment's stability during the welding process. This effectively solves the problem that while existing ultrasonic welding machines for automotive interiors meet the welding and transfer requirements of most automotive interiors, their clamping components are not compatible with the spare tire compartment's shape, making it difficult to effectively clamp the spare tire compartment and directly affecting its stability during the welding process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] This utility model embodiment provides a clamping mechanism for a spare tire compartment welding conveying device. The spare tire compartment welding workpiece table and the main body of the clamping mechanism are designed to match the shape and structure of the spare tire compartment, making it highly compatible with the shape of the spare tire compartment and facilitating effective clamping, thereby ensuring its stability during the welding process and solving the problems mentioned in the background art.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] A clamping mechanism for a spare tire compartment welding conveying device includes a spare tire compartment welding workpiece table 1 and a clamping mechanism body 2 for welding conveying of the spare tire compartment. The spare tire compartment welding workpiece table 1 includes a spare tire panel table 11, a right rear longitudinal beam reinforcing plate table 12, and a left rear longitudinal beam reinforcing plate table 13. The spare tire panel table 11 is located on the top surface of the chain conveyor belt. The right rear longitudinal beam reinforcing plate table 12 and the left rear longitudinal beam reinforcing plate table 13 are respectively fixedly installed at the center of both sides of the spare tire panel table 11. The top surfaces of the right rear longitudinal beam reinforcing plate table 12 and the left rear longitudinal beam reinforcing plate table 13 are also fixedly installed. Equipped with positioning pins 14, in order to ensure a more secure placement of the spare tire compartment, spare tire panel platform 11, right rear longitudinal beam reinforcement plate platform 12, and left rear longitudinal beam reinforcement plate platform 13 are designed to correspond to the spare tire panel, right rear longitudinal beam reinforcement plate, and left rear longitudinal beam reinforcement plate, thereby making the transfer of the spare tire compartment components stable and reliable. Furthermore, through the design of positioning pins 14, the right rear longitudinal beam reinforcement plate and left rear longitudinal beam reinforcement plate located on the top surface of the right rear longitudinal beam reinforcement plate platform 12 and left rear longitudinal beam reinforcement plate platform 13 can be positioned to prevent misalignment with the spare tire panel during transfer and facilitate precise welding.

[0026] The clamping mechanism body 2 is composed of a first reinforcing plate clamp 21 and a second reinforcing plate clamp 22 arranged in parallel. A spare tire panel locator 23 is provided between the first reinforcing plate clamp 21 and the second reinforcing plate clamp 22. Both the first reinforcing plate clamp 21 and the second reinforcing plate clamp 22 include two sets of U-shaped clamps 24 symmetrically distributed on both sides of the spare tire compartment welding workpiece table 1. The inside of the U-shaped clamp 24 is movably installed with a clamping plate 242 through a telescopic cylinder 241. The side of the U-shaped clamp 24 away from the spare tire compartment welding workpiece table 1 and the inner wall of the welding equipment mounting frame are fixedly connected by a mounting base 243. The spare tire panel, the right rear longitudinal beam reinforcing plate, and the left rear longitudinal beam reinforcing plate to be welded and transferred are placed on the corresponding spare tire panel table 11, right rear longitudinal beam reinforcing plate table 12, and left rear longitudinal beam reinforcing plate table 13. The top surface of the rear longitudinal beam reinforcing plate platform 13 is positioned by the positioning pin 14. Then, it is conveyed to the welding equipment by the action of the chain conveyor belt and the conveying is paused. At this time, the reinforcing plate is unfolded downward by the telescopic cylinder 241. Under its action, the clamping plate 242 continues to descend until it clamps the two ends of the rear longitudinal beam reinforcing plate inside the U-shaped clamp 24. After the clamping and positioning are completed, the welding equipment welds the spare tire panel and the left and right rear longitudinal beam reinforcing plates. After the welding is completed, the clamping plate 242 is reset, and the chain conveyor belt continues to run. The spare tire compartment after welding is conveyed to the next production and processing step. The spare tire compartment welding workpiece table and the main body of the clamping mechanism are highly compatible with the shape of the spare tire compartment, which facilitates effective clamping and ensures its stability during the welding process.

[0027] Furthermore, in this embodiment, please refer to Figure 2 The thickness of the right rear longitudinal beam reinforcing plate platform 12 and the left rear longitudinal beam reinforcing plate platform 13 is smaller than that of the spare tire panel platform 11. The right rear longitudinal beam reinforcing plate platform 12 and the left rear longitudinal beam reinforcing plate platform 13 pass through the interior of the adjacent U-shaped clamps 24 and are located at the bottom of the clamping plate 242, which facilitates clamping and effectively avoids obstructing the transfer of the spare tire compartment welding workpiece platform 1.

[0028] Furthermore, in this embodiment, please refer to Figure 4The spare tire panel locator 23 includes an I-shaped mounting frame 231, a telescopic cylinder 232 for the spare tire panel, a positioning pressure seat 233, and guide members 234. The four corners of the I-shaped mounting frame 231 are fixedly connected to the adjacent U-shaped clamps 24. The positioning pressure seat 233 is movably mounted on the bottom of the I-shaped mounting frame 231 through the telescopic cylinder 232 for the spare tire panel. Guide members 234 are movably mounted on both sides of the top surface of the positioning pressure seat 233 and the bottom surface of the I-shaped mounting frame 231 near the telescopic cylinder 232 for the spare tire panel. The design of the spare tire panel locator 23 allows for positioning of the spare tire panel during welding, which is beneficial to the overall stability and further improves the stability and reliability of the welding process. While clamping the rear longitudinal beam reinforcing plate, the telescopic cylinder 232 for the spare tire panel unfolds downwards, and under its action, the positioning pressure seat 233 presses down to position the spare tire panel. During the entire pressing and positioning process, the guide members 234 unfold accordingly, which is beneficial for accurate positioning.

[0029] Furthermore, in this embodiment, please refer to Figure 5 The bottom surface of the inner wall of the U-shaped clamp 24 and the bottom surface of the clamping plate 242 are provided with clamping teeth 244. A limiting slide 245 is fixedly installed at one end of the clamping plate 242 near the side of the inner wall of the U-shaped clamp 24. A limiting groove 246 adapted to the limiting slide 245 is opened on the side of the inner wall of the U-shaped clamp 24. The limiting slide 245 and the limiting groove 246 are slidably connected. The design of the clamping teeth 244 can make the clamping effect better and prevent slippage. At the same time, the design of the limiting slide 245 and the limiting groove 246 can ensure more stable clamping.

[0030] It should be noted that telescopic cylinders are existing technology, and will not be discussed in detail here.

[0031] In this embodiment, the specific implementation scenario is as follows: the spare tire panel, right rear longitudinal beam reinforcement plate, and left rear longitudinal beam reinforcement plate to be welded are placed on the top surfaces of the corresponding spare tire panel table 11, right rear longitudinal beam reinforcement plate table 12, and left rear longitudinal beam reinforcement plate table 13, respectively. The rear longitudinal beam reinforcement plates are positioned using positioning pins 14. Subsequently, they are conveyed to the welding equipment by a chain conveyor belt, and the conveying is paused. At this time, the reinforcement plates are extended downwards by a telescopic cylinder 241. Under its action, the clamping plate 242 continuously descends until the two ends of the rear longitudinal beam reinforcement plates are clamped inside the U-shaped clamp 24. While the reinforcing plate is clamped, the spare tire panel is extended downward by the telescopic cylinder 232. Under its action, the positioning pressure seat 233 presses down to position the spare tire panel. After clamping and positioning are completed, the welding equipment welds the spare tire panel and the left and right rear longitudinal beam reinforcing plates. After welding is completed, the clamping plate 242 and the positioning pressure seat 233 are reset. At the same time, the chain conveyor belt continues to run, and the spare tire compartment after welding is conveyed to the next production and processing step. The spare tire compartment welding workpiece table and the main body of the clamping mechanism are highly compatible with the shape of the spare tire compartment, which facilitates effective clamping and ensures its stability during the welding process.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
