A second screw that mates with the second threaded hole is fixed on the lower surface of the support plate. The second screw is screwed onto the second threaded hole. The lower surface of the support plate is in close contact with the upper surface of the mounting platform. A limiting cylinder is fixed on the upper surface of the support plate. The limiting cylinder and the second threaded hole are located on the same central axis. A vertical valve cylinder to be welded is fitted around the limiting cylinder. The upper surface of the support plate abuts against the lower surface of the vertical valve cylinder.

[0006] Preferably, the first threaded hole penetrates the movable plate, and the length of the first screw is greater than the length of the first threaded hole.

A horizontally positioned fixed plate 2 is fixed to the top of the mounting frame 1. A push-pull device 30 is mounted on the fixed plate 2. The push-pull device 30 can be a hydraulic cylinder or a pneumatic cylinder. The push-pull device 30 is connected to a vertically positioned movable plate 3, and the push-pull device 30 drives the movable plate 3 to move horizontally. The movable plate 3 is provided with a first threaded hole, the central axis of which is parallel to the pushing and pulling direction of the push-pull device 30. The positioning cylinder 31 is vertically arranged, and a first screw 32 that mates with the first threaded hole is fixed on the positioning cylinder 31. The first screw 32 and the positioning cylinder 31 are located on the same central axis. The first screw 32 is screwed onto the first threaded hole. The positioning cylinder 31 is close to the end of the movable plate 3 away from the push-pull device 30. A transverse valve cylinder 5 to be welded is sleeved on the outside of the positioning cylinder 31. The outer diameter of the positioning cylinder 31 is adapted to the inner diameter of the transverse valve cylinder 5.

[0017] A lifting device 11 is installed on the mounting frame 1. The lifting device 11 can be a hydraulic cylinder or a pneumatic cylinder. The lifting device 11 is connected to a mounting platform 12. The lifting device 11 drives the mounting platform 12 to move vertically up and down. A second threaded hole is provided on the upper end face of the mounting platform 12. The central axis of the first threaded hole and the central axis of the second threaded hole are located on the same vertical plane. A second screw 40 that mates with the second threaded hole is fixed on the lower end face of the support plate 4. The second screw 40 is screwed on the second threaded hole. The lower end face of the support plate 4 is close to the upper end face of the mounting platform 12. A limiting cylinder 41 is fixed on the upper end face of the support plate 4. The limiting cylinder 41 and the second threaded hole are located on the same central axis. A vertical valve cylinder 6 to be welded is sleeved on the outside of the limiting cylinder 41. The outer diameter of the limiting cylinder 41 is adapted to the inner diameter of the vertical valve cylinder 6. The upper end face of the support plate 4 abuts against the lower end face of the vertical valve cylinder 6.

[0018] In order to make the movable plate 3 run more smoothly and less prone to tilting, the upper surface of the fixed plate 2 is provided with several guide grooves 25 parallel to the moving direction of the movable plate 3, and the bottom end of the movable plate 3 is fixed with several guide blocks 35 corresponding to the guide grooves 25, and the guide blocks 35 are embedded in the guide grooves 25.

[0019] Example 2:

[0020] In order to make the movable plate 3 thinner and reduce its weight, the first threaded hole penetrates the movable plate 3, and the length of the first screw 32 is greater than the length of the first threaded hole.

[0021] In order to ensure that the support plate 4 can fit tightly against the mounting platform 12, so that the height of the vertical valve cylinder 6 can be easily guaranteed, the length of the second screw 40 is less than the depth of the second threaded hole.

[0022] Example 3:

[0023] To prevent the vertical valve cylinder 6 from accidentally falling and damaging the lifting device 11, the lifting device 11 is located below the fixed plate 2. The fixed plate 2 is provided with a clearance hole that allows the mounting platform 12 to pass through, and the lower projection of the support plate 4 completely covers the clearance hole.

[0024] Example 4:

[0025] In order to keep the device in a horizontal position and ensure the accuracy of the positional relationship between the horizontal valve cylinder 5 and the vertical valve cylinder 6, the bottom of the mounting frame 1 is provided with several adjustable support feet 10, and a level 15 is fixed on the upper surface of the fixing plate 2.

[0026] The working process of this utility model:

[0027] In operation, this adjustable valve body welding and positioning device involves placing the vertical valve cylinder 6 around the limiting cylinder 41, then using the lifting device 11 to raise the vertical valve cylinder 6 to the required height. Next, the horizontal valve cylinder 5 is placed around the positioning cylinder 31, and the push-pull device 30 pushes the horizontal valve cylinder 5 towards the vertical valve cylinder 6 until they are in contact. When the horizontal valve cylinder 5 is about to contact the vertical valve cylinder 6, the push-pull device 30 can be paused. The circumferential orientation of the horizontal valve cylinder 5 is then adjusted so that its end aligns with the outer wall of the vertical valve cylinder 6. The push-pull device 30 is then used to push the horizontal valve cylinder 5 towards the vertical valve cylinder 6 again. If necessary, the push-pull device can be paused multiple times to adjust the horizontal valve cylinder 5. Welding can then proceed once the vertical valve cylinders 6 are in contact.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
