[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0035] Example 1

[0036] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a welding device for a tantalum-lined vacuum pressure vessel. The welding device for a tantalum-lined vacuum pressure vessel includes a base plate 1, a drive mechanism 2, a clamping device 3, a support member 4, and a fastening mechanism 5. Through the cooperation of the support member 4 and the drive mechanism 2, the clamping device 3 clamps the pressure vessel under the action of the weight of the vessel. It does not require multiple rotations of the screw for adjustment or manual operation of the clamping plate to achieve fixation. Moreover, the clamping force is unevenly distributed, ensuring the alignment of the vessel body and the welding fixture.

[0037] Specifically, the drive mechanism 2 is installed on the top of the base plate 1 and includes a base 25 fixedly connected to the base plate 1. The base 25 has a groove 24 inside, a first toothed plate 21 is slidably connected inside the base 25, and a gear 22 is rotatably connected inside the base 25. The first toothed plate 21 and the gear 22 mesh.

[0038] The rotation of the gear 22 inside the base 25 drives the first toothed plate 21 and another first toothed plate 21 to move left and right, while simultaneously driving the clamping device 3 to clamp. The groove 24 can limit the position of the first toothed plate 21.

[0039] Specifically, the clamping device 3 is mounted on the top of the drive mechanism 2, including a clamping plate 34 mounted on the top of the drive mechanism 2.

[0040] The first toothed plate 21 and the other first toothed plate 21 approach each other, which can drive the clamping device 3 to clamp the pressure tank. Moving in the opposite direction can make the clamping device 3 release the pressure tank.

[0041] Specifically, the support member 4 is installed on the top of the drive mechanism 2, including a support plate 46 set on the top of the base 25, a second toothed plate 42 is fixedly connected to the bottom of the support plate 46, a spring 43 is fixedly connected to the bottom of the second toothed plate 42, and the lower end of the spring 43 is fixedly connected to the inner wall of the base 25.

[0042] The support plate 46 moves downward, causing the second toothed plate 42 to move simultaneously. The clamping plate 34 clamps inward, and the spring 43 is compressed. When the support plate 46 is not under force, the spring 43 can drive the second toothed plate 42 to support the plate 46 to return to its original position.

[0043] Specifically, the fastening mechanism 5 is installed on the outside of the clamping device 3, including a fixed block 55 fixedly connected to one side of the clamping device 3, a rotating block 53 slidably connected inside the fixed block 55, a sliding groove 53-2 opened on the outer surface of the rotating block 53, a short column 53-1 fixedly connected inside the fixed block 55 and slidably connected in the sliding groove 53-2, a bottom block 54 fixedly connected to the bottom of the rotating block 53, and a rubber pad 52 fixedly connected to the bottom of the bottom block 54.

[0044] The handle 51 makes rotation easier. By applying downward pressure, the handle 51 can rotate the rotating block 53. The rubber pad 52 at the bottom compresses and deforms the base 25. The short column 53-1 moves in the sliding groove 53-2 to fix the fixing block 55 and the reinforcing plate 33, so that the clamping device 3 does not move easily when clamping the pressure tank.

[0045] Example 2

[0046] Reference Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0047] Specifically, a fixing groove 26 is provided inside the base 25, and the first toothed plate 21 is slidably connected in the fixing groove 26.

[0048] The first toothed plate 21 can be limited by setting the fixing groove 26.

[0049] The base 25 has a fixing groove 26 inside, and the first toothed plate 21 is slidably connected in the fixing groove 26.

[0050] The T-slot 23 can limit the T-block 31 at the bottom of the clamping device 3.

[0051] A T-shaped block 31 is fixedly connected to the bottom of the clamping plate 34, and a T-shaped groove 23 is opened on the top of the base 25, and the T-shaped block 31 is slidably connected in the T-shaped groove 23.

[0052] The reinforcing plate 33 can provide a stronger and more secure gripping effect when the clamping plate 34 is clamped.

[0053] A reinforcing plate 33 is fixedly connected to the outside of the clamping plate 34, and the reinforcing plate 33 is fixedly connected to the surface of the fixing block 55.

[0054] By rotating the handle 51, it is easier to rotate the rotating block 53, and the positioning groove in the sliding groove 53-2 can limit the short column 53-1.

[0055] The top of the rotating block 53 is fixedly connected to a handle 51, and a positioning groove is opened in the sliding groove 53-2, which cooperates with the short column 53-1.

[0056] By setting anti-slip pads, the friction between the clamping plate 34 and the tank can be increased when clamping, thus improving the fixing effect. By setting the curved surface, it can better fit the tank.

[0057] One side of the clamping plate 34 is provided with an arc surface, and an anti-slip pad is fixedly connected to the arc surface.

[0058] The support column 44 at the bottom of the support member 4 can prevent the support plate 46 from tilting and provide support.

[0059] There are two first toothed plates 21, and gear 22 meshes with the second toothed plate 42.

[0060] A support column 44 is fixedly connected to the bottom of the support plate 46, and the support column 44 is slidably connected to the base 25.

[0061] A T-shaped block 31 at the bottom of one clamping plate 34 is fixedly connected to one of the first toothed plates 21, and a connecting block 32 is fixedly connected to the lower end of the T-shaped block 31 at the bottom of the other clamping plate 34. The connecting block 32 is fixedly connected to the other first toothed plate 21.

[0062] The limiting grooves 45 and limiting blocks 41 on both sides of the second toothed plate 42 can stabilize the second toothed plate 42 when it meshes with the gear 22.

[0063] Limiting grooves 45 are provided on both sides of the second toothed plate 42. Limiting blocks 41 are slidably connected in the limiting grooves 45, and the limiting blocks 41 are fixedly connected to the inner wall of the base 25.

[0064] When in use, the pressure tank is placed on the surface of the support 4, and the support 4 is pressed down by gravity. At the same time, the second toothed plate 42 moves and drives the gear 22 to rotate. The spring 43 is compressed, and the gear 22 drives the first toothed plate 21 and another first toothed plate 21 to move inward. The movement of the first toothed plate 21 drives the connecting block 32 and the two clamping plates 34 to move inward at the same time to clamp the pressure tank.

[0065] After clamping the pressure tank, rotate the handle 51 to make the rotating block 53 rotate. With the cooperation of the sliding groove 53-2 and the short column 53-1, the rotating block 53 rotates and moves down. The rubber pad 52 at the bottom will apply pressure to the base 25, causing the short column 53-1 to move into the positioning groove, thereby fixing the fixing block 55. This achieves reinforcement of the reinforcing plate 33 and the clamping plate 34, improving the fixing effect and stability.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
