Technical Field

[0001] This utility model relates to the field of welding, and more specifically, it relates to a clamping welding device for upper and lower tanks. Background Technology

[0002] With social progress and the improvement of people's living standards, the demand for portable products is increasing day by day. Small handheld gas canisters have become an ideal choice for outdoor adventure, medical first aid, industrial inspection and other fields due to their small size, light weight and easy portability. Small gas canisters can be produced by welding the upper and lower canisters together.

[0003] Traditional welding methods mostly employ manual or semi-automatic welding techniques. During welding, workers need to manually adjust the position of the workpiece, which not only increases labor intensity but also easily leads to inaccurate welding positions, affecting weld quality. If conventional clamping tools such as bench vises are used to fix it, it is difficult to position and clamp it due to the curved shape of the tank side.

[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clamping and welding device for upper and lower tanks.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: it includes a base plate and a housing fixedly connected thereto. A welding head is fixedly connected to the upper end of the base plate away from the housing. Two fixing components are slidably connected to the top surface of the base plate. The line connecting the welding head and the housing intersects with the line connecting the two fixing components. The fixing components include a lower fixing plate. A plurality of cylinder rods are slidably connected to the top surface of the lower fixing plate. An upper fixing plate is fixedly connected to the top end of the cylinder rods. A cylindrical groove is formed on one wall of the upper fixing plate and the lower fixing plate opposite to the upper fixing plate and the lower fixing plate on another set of fixing components.

[0007] By adopting the above technical solution, this device installs a shell on the top surface of the base plate, and slides two fixing components on the top of the base plate. The two fixing components are installed opposite each other. The fixing components are moved horizontally and towards the center position to fix the tank placed in the middle position. The tank consists of an upper part and a lower part. The fixing components are composed of an upper fixing plate, a lower fixing plate and a cylinder rod connecting the two. The two lower fixing plates fix the lower half of the tank, and the two upper fixing plates fix the upper half of the tank. When the fixing components move towards the center position, the tank is fixed.

[0008] The present invention is further configured such that: a movable groove is provided at the upper end of the base plate, and the lower fixed plate moves horizontally through the movable groove.

[0009] By adopting the above technical solution, the lower fixed plate moves horizontally through the moving groove, and the moving position of the moving plate is limited by the relationship between the lower fixed plate and the moving groove.

[0010] The present invention is further configured such that a turntable is rotatably connected to the top surface of the base plate at a position between the two lower fixed plates.

[0011] By adopting the above technical solution, a turntable is used to place the tank. The turntable can rotate, and the tank is rotated and welded by the rotation of the turntable.

[0012] The present invention is further configured such that: a concave plate is fixedly connected to the side of the shell near the welding head, and a triangular strip is fixedly connected to the center of the concave plate.

[0013] By adopting the above technical solution, a triangular strip is fixedly connected at the center of the concave plate. The connection position of the triangular strip embedded in the tank body is such that when the concave plate and the two fixing components fix the tank body on the turntable, the welding work is more stable.

[0014] The present invention is further configured such that the arc length of the groove on the upper fixing plate projected onto the horizontal plane is greater than the arc length of the groove on the lower fixing plate projected onto the horizontal plane.

[0015] By adopting the above technical solution, the cross-sectional area of ​​the groove in the upper fixing plate is larger than that in the lower fixing plate.

[0016] The present invention is further configured such that the cylinder rod is a cross rod.

[0017] By adopting the above technical solution, the cross rod structure makes the cylinder rod support more stable and can better support the upper fixing plate.

[0018] In summary, this utility model has the following beneficial effects: by installing the upper fixing plate and the lower fixing plate, the upper fixing plate and the lower fixing plate can be moved to fix the tank placed on the top of the turntable. The fixed tank can be better welded at the center connection position of the tank. It is fixed in three directions. When the turntable rotates, the fixed connection welding head welds the connection.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example:

[0024] Upper and lower tank clamping welding device, such as Figure 1 As shown, the assembly includes a base plate 11 and a housing 1 fixedly connected thereto. A welding head 4 is fixedly connected to the upper end of the base plate 11 away from the housing 1. Two fixing components are slidably connected to the top surface of the base plate 11. The line connecting the welding head 4 and the housing 1 intersects with the line connecting the two fixing components. The fixing components include a lower fixing plate 22. Several cylinder rods 23 are slidably connected to the top surface of the lower fixing plate 22. An upper fixing plate 21 is fixedly connected to the top of the cylinder rods 23. A cylindrical groove is formed on one wall of the upper fixing plate 21 and the lower fixing plate 22 relative to the upper fixing plate 21 and the lower fixing plate 22 on another set of fixing components. A moving groove 111 is formed at the upper end of the base plate 11. The lower fixing plate 22 moves horizontally through the moving groove 111. A turntable 3 is rotatably connected to the top surface of the base plate 11 at a position between the two lower fixing plates 22.

[0025] like Figure 2 As shown, the base plate 11 is provided with a moving groove 111 below the fixed assembly. The lower fixed plate 22 moves horizontally through the moving groove 111. The cross-section of the groove in the upper fixed plate 21 is larger than that in the lower fixed plate 22. The cylinder rod 23 is a cross rod.

[0026] like Figure 3 As shown, a concave plate 12 is provided on the inner wall of the housing 1, and a triangular strip 121 is fixedly connected to the center of the concave plate 12.

[0027] This device uses a housing 1 mounted on the top surface of a base plate 11. Two fixing components are slidably connected to the top of the base plate 11. The two fixing components are installed opposite each other. By moving the fixing components horizontally and towards the center position, the tank placed in the middle position is fixed. The tank consists of an upper part and a lower part. Its fixing components consist of an upper fixing plate 21, a lower fixing plate 22, and a cylinder rod 23 connecting the two. The cross rod structure makes the support of the cylinder rod 23 more stable and can better support the upper fixing plate 21. The cross-sectional area of ​​the groove in the upper fixing plate 21 is larger than that in the lower fixing plate 22. The two lower fixing plates 22 fix the lower half of the tank, and the two upper fixing plates 21 fix the upper half of the tank. When the fixing components move towards the center position, they fix the tank. The lower fixing plate is fixed and moves horizontally through the moving groove 111. The moving position of the moving plate is limited by the lower fixing plate and the moving groove 111. A triangular strip 121 is fixedly connected at the center of the concave plate 12. The triangular strip 121 is embedded in the connection position of the tank. When the concave plate 12 and the two fixing components fix the tank on the turntable 3, the welding work is more stable. By installing the upper fixing plate 21 and the lower fixing plate 22, the upper fixing plate 21 and the lower fixing plate 22 can be moved to fix the tank placed at the top of the turntable 3. The fixed tank can be better welded at the center connection position of the tank. It is fixed in three directions. When the turntable 3 rotates, the fixedly connected welding head 4 welds the connection, so the welding work can be completed better.
