Description

Technical Field

[0001] This utility model belongs to the field of positioning tooling technology, specifically a positioning tooling for welding seams of metal cans. Background Technology

[0002] Currently, many products use metal cans for packaging. Metal can packaging has advantages such as good sealing performance. Therefore, metal can packaging has been widely used in food, pharmaceutical, chemical and other fields. Currently, many metal cans for products are round in shape, which makes welding the seams difficult. Therefore, a metal can seam welding positioning tool is needed.

[0003] A search revealed that patent CN220330467U discloses a positioning fixture for welding seams in metal cans, relating to the field of positioning fixture technology. The fixture includes an adjustment mechanism with clamping components on its surface. One end of the adjustment mechanism is fixedly connected to the clamping mechanism. The adjustment mechanism also includes a support frame, which is fixedly connected to the surface of the clamping components. A sliding column is movably connected to the surface of the support frame, and one end of the sliding column is fixedly connected to a support plate. One end of the support plate is fixedly connected to a base plate. This invention utilizes the cooperation between a driving component and a fixed plate. The driving component rotates the fixed plate, and the metal can is clamped by adjusting the clamping blocks, achieving the effect of rotating the metal can fixed on the adjusting clamping blocks. This allows the metal can to be welded at all angles. The clamping blocks and springs work together; the clamping blocks fix the springs, and the springs, along with the clamping blocks, work together to clamp the metal cans according to their size, compressing the springs for optimal gripping.

[0004] While existing technologies can clamp the metal can using two fixed blocks, subsequent rotational welding requires adjusting the clamping force to ensure proper rotation. This inconvenience and instability during rotation negatively impacts welding quality. To address these issues, we provide a metal can joint welding positioning fixture. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a metal can joint welding positioning tool.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal can joint welding positioning fixture, comprising a U-shaped base, two opposing guide rods fixedly connected to the inner wall of the U-shaped base, a movable frame slidably sleeved between the two guide rods, a fixed frame fixedly connected to the right end of the U-shaped base, and rotating shafts fixedly connected to the top ends of both the movable frame and the fixed frame. Circular toothed plates are rotatably connected to one end of each of the two rotating shafts. A transmission mechanism for driving the two circular toothed plates to rotate synchronously is provided in the middle of the U-shaped base, and the circular toothed plates on the movable frame slide on the transmission mechanism. A positioning mechanism for fixing the metal can is provided on each of the two circular toothed plates.

[0007] Preferably, the transmission mechanism includes a toothed roller, which is rotatably connected to both sides of the inner wall of the U-shaped base and meshes with two circular toothed plates. A motor for driving the toothed roller to rotate is installed on the side of the U-shaped base.

[0008] Preferably, the positioning mechanism includes a support plate and two rotating rods. The support plate is fixedly connected to the side of the circular toothed plate. The two rotating rods are rotatably connected inside the circular toothed plate and are located on both sides of the support plate. One end of each of the two rotating rods is fixedly connected to an arc-shaped plate, and the top of each of the two arc-shaped plates is fixedly connected to a rubber airbag. The other side of the circular toothed plate is provided with a linkage mechanism for driving the two rotating rods to rotate relative to each other.

[0009] Preferably, the linkage mechanism includes a spur gear plate and two gears. The two gears are respectively fixedly connected to the ends of the two rotating rods away from the arc plate. The spur gear plate is located between the two gears and meshes with the two gears. The spur gear plate is elastically slidably disposed on the side of the circular gear plate.

[0010] Preferably, the circular toothed plate has a mounting groove on its side, a guide rod is fixedly connected to the inner wall of the mounting groove, a compression spring and a moving block are sleeved on the surface of the guide rod, and the moving block is slidably disposed in the mounting groove. The top end of the compression spring is fixedly connected to the inner top wall of the mounting groove, the bottom end of the compression spring is fixedly connected to the moving block, one end of the moving block is connected to the side of the straight toothed plate, and a pull rod is fixedly connected to the top end of the straight toothed plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, through the coordinated arrangement of a U-shaped base, guide rod, movable frame, fixed frame, rotating shaft, circular toothed plate, transmission mechanism, and positioning mechanism, allows the straight toothed plate on the right circular toothed plate to be pulled upwards, further placing the metal can body on the right support plate and securing it between two rubber airbags. The can lid is then clamped and fixed on the left circular toothed plate. The operator then slides the left circular toothed plate to bring the can lid and body into contact, allowing welding to begin. During welding, the motor drives the toothed roller to rotate, causing the two circular toothed plates to rotate synchronously, thus welding the metal can joint. The metal can maintains stability during rotation and will not shift. After welding is complete, the operator pulls the left straight toothed plate upwards and moves the left circular toothed plate away from the right circular toothed plate, separating the welded metal can from the left circular toothed plate. Finally, it can be disassembled from the right circular toothed plate. The operation is more flexible and convenient, allowing for easy adjustment of the distance between the two circular toothed plates and enabling their synchronous rotation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-6 As shown, this embodiment proposes a metal can joint welding positioning fixture, including a U-shaped base 1. Two opposing guide rods 3 are fixedly connected to the inner wall of the U-shaped base 1. A movable frame 5 is slidably sleeved between the two guide rods 3, allowing the movable frame 5 to slide stably on the two guide rods 3 without tilting. A fixed frame 6 is fixedly connected to the right end of the U-shaped base 1. Rotating shafts 7 are fixedly connected to the top ends of both the movable frame 5 and the fixed frame 6. Circular toothed plates 8 are rotatably connected to one end of each of the two rotating shafts 7, allowing the two circular toothed plates 8 to rotate on the top ends of the fixed frame 6 and the movable frame 5 respectively via their corresponding rotating shafts 7. A transmission mechanism for driving the two circular toothed plates 8 to rotate synchronously is provided in the middle of the U-shaped base 1. Furthermore, the circular toothed plate 8 on the movable frame 5 slides on the transmission mechanism. With the transmission mechanism in place, the two circular toothed plates 8 can be driven to rotate synchronously, thereby causing the metal can to rotate between the two circular toothed plates 8. Both circular toothed plates 8 are equipped with positioning mechanisms for fixing the metal can. The positioning mechanisms can fix the two parts of the metal can onto the two circular toothed plates 8 respectively, which is beneficial for subsequent rotational welding processing. Therefore, the positioning efficiency of the metal can is improved, as is the welding efficiency of the metal can. The machinery, parts and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0022] like Figure 1 and Figure 2 As shown, the transmission mechanism includes a toothed roller 4, which is rotatably connected to both sides of the inner wall of the U-shaped base 1. The toothed roller 4 meshes with two circular toothed plates 8. A motor 2 for driving the toothed roller 4 to rotate is installed on the side of the U-shaped base 1. With the above structure, when the metal can is fixed between the two circular toothed plates 8, the motor 2 drives the toothed roller 4 to rotate. Since both circular toothed plates 8 mesh with the toothed roller 4, they will rotate synchronously, thus driving the metal can to rotate. This facilitates welding operations on its surface, improves the flexibility of the device, and allows one of the circular toothed plates 8 to slide horizontally on the toothed roller 4 without affecting normal meshing. This not only allows for easy adjustment of the distance between the two circular toothed plates 8 but also enables synchronous rotation of the two circular toothed plates 8.

[0023] like Figure 1 , Figure 5 and Figure 6 As shown, the positioning mechanism includes a support plate 11 and two rotating rods 15. The support plate 11 is fixedly connected to the side of the circular toothed plate 8. The two rotating rods 15 are rotatably connected inside the circular toothed plate 8 and are located on both sides of the support plate 11. One end of each rotating rod 15 is fixedly connected to an arc-shaped plate 10, and the top of each arc-shaped plate 10 is fixedly connected to a rubber airbag 9. The other side of the circular toothed plate 8 is provided with a linkage mechanism for driving the two rotating rods 15 to rotate relative to each other. With the above structure, the two rotating rods 15 can be rotated relative to each other by using the linkage mechanism, further controlling the two rubber airbags 9 to move away from each other, so that personnel can place the metal can on the support plate 11, and then personnel can use the linkage mechanism to... By repositioning the two rubber airbags 9 closer together, one half of the metal can is fixed, and then the other half of the metal can is fixed to another circular toothed plate 8. By sliding one of the circular toothed plates 8, the two parts of the metal can are welded together. Specifically, the two metal can parts are the can lid and the can body. The operator can place the can body on the right circular toothed plate 8 and the can lid on the left circular toothed plate 8. The operator can then push the left circular toothed plate 8 to move it, thereby fitting the can lid and the can body together for easy welding. In addition, the rubber airbags 9 are made of rubber and are hollow inside, so they will not cause compression damage to the metal can and can adapt to the welding of metal cans of more different sizes.

[0024] like Figure 3 As shown, the linkage mechanism includes a straight toothed plate 12 and two gears 13. The two gears 13 are respectively fixed to the ends of the two rotating rods 15 away from the arc plate 10. The straight toothed plate 12 is located between the two gears 13 and meshes with the two gears 13. The straight toothed plate 12 is elastically slidably disposed on the side of the circular toothed plate 8. With the above structure, when the personnel slide the straight toothed plate 12 downward, they can drive the two gears 13 to rotate relative to each other, which further causes the two rotating rods 15 to drive the two arc plates 10 to swing relative to each other. This makes it convenient for personnel to fix the metal can. In addition, the straight toothed plate 12 has the feature of automatic reset, thus reducing the manual reset operation of personnel.

[0025] like Figures 3 to 5As shown, a mounting groove 17 is provided on the side of the circular toothed plate 8. A guide rod 19 is fixedly connected to the inner wall of the mounting groove 17. A compression spring 18 and a moving block 16 are sleeved on the surface of the guide rod 19. The moving block 16 is slidably disposed in the mounting groove 17. The top end of the compression spring 18 is fixedly connected to the inner top wall of the mounting groove 17, and the bottom end of the compression spring 18 is fixedly connected to the moving block 16. One end of the moving block 16 is connected to the side of the straight toothed plate 12. A pull rod 14 is fixedly connected to the top end of the straight toothed plate 12. With the above structure, the straight toothed plate 12 can slide stably on the circular toothed plate 8 without deviation. After the personnel release the straight toothed plate 12, it can automatically reset under the elastic force of the compression spring 18, thereby clamping and fixing the metal can. In addition, when the two circular toothed plates 8 rotate synchronously through the toothed roller 4, the corresponding gear 13, straight toothed plate 12 and pull rod 14 will not touch the moving frame 5 and the fixed frame 6.

[0026] The working principle and usage process of this utility model are as follows: First, pull the straight toothed plate 12 on the right circular toothed plate 8 upwards, thereby moving the two arc-shaped plates 10 away from each other. Then, place the metal can body on the right support plate 11, between the two rubber airbags 9. When the straight toothed plate 12 is released, it can automatically reset under the elastic force of the compression spring 18, thereby clamping and fixing the metal can. Then, fix the can lid on the left circular toothed plate 8 using the above method. Subsequently, the operator slides the left circular toothed plate 8 to move it, so that the can lid and the can body fit together, and welding can begin. During the welding process, the operation of the motor 2 drives the toothed roller 4. The rotation causes the two circular toothed plates 8 to rotate synchronously, thereby welding the joint of the metal can. After the metal can is welded, the operation of motor 2 is stopped, and the circular toothed plates 8 are rotated so that the support plate 11 is directly below. Then, the operator pulls the left straight toothed plate 12 upward and pulls the left circular toothed plate 8 away from the right circular toothed plate 8, so that the welded metal can is separated from the left circular toothed plate 8. Finally, it can be disassembled from the right circular toothed plate 8. The operation is more flexible and convenient, and it can not only easily adjust the distance between the two circular toothed plates 8, but also achieve synchronous rotation of the two circular toothed plates 8.
