Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular to an anti-deformation welding tool for simultaneous welding of multiple threaded seats. Background Art

[0002] Glove boxes used in nuclear power plants are used to clean items containing radioactive samples. The glove box contains several valves, which control the flow of liquid in the glove box's pipes by rotating the valve stems. The valve handles extend outside the glove box and can be operated from outside. During use, wastewater and exhaust gases are generated within the glove box. Leakage is essential, as the valve stems and the glove box must rotate relative to each other, ensuring a tight seal between them.

[0003] Currently, glove boxes are equipped with multiple valves, which extend from threaded sockets on the box body. To ensure proper rotation of the valve stems, they must be coaxial with the sockets. Therefore, the welded sockets must all be perpendicular to the box panel. Otherwise, the valve stems will become stuck when rotating, leading to leakage.

[0004] Reference Figure 1 The box panel 27 has multiple circular holes 28. The threaded seat includes, from top to bottom, a threaded portion 29, a welding portion 30, and a base 31. When welding the threaded seat, it is necessary to place the threaded seat into the circular holes 28 of the box panel 27, and then weld the welding portion 30 of the threaded seat to the box panel 27. The threaded seat and the box panel 27 have different thicknesses. When the threaded seat is placed into the circular holes 28 of the box panel 27, the welding portion 30 has a base 31 at the bottom, causing the height of the welding portion 30 to be slightly higher than the box panel 27. In this case, the box panel 27 needs to be raised before welding can be performed. This welding method can easily cause the threaded seat to deflect during the welding process. Summary of the Invention

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0036] An embodiment of the present application discloses an anti-deformation welding tool for simultaneously welding multiple threaded seats.

[0037] Example 1:

[0038] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A deformation-preventing welding fixture for the simultaneous welding of multiple threaded seats includes a rectangular plate 1 with a sealing gasket 8 fixedly mounted on its top wall. The sealing gasket 8 is in the shape of a rectangular ring and is located on the outer periphery of the plate 1. A rectangular box panel 27 is provided with nine circular holes 28. The box panel 27 is placed on the sealing gasket 8, and the length and width of the box panel 27 are smaller than those of the plate 1. The upper surface of the plate 1 has nine positioning holes 2, which correspond one-to-one with the nine circular holes 28.

[0039] First, place the box panel 27 on the flat plate 1. Adjust the flat plate 1 so that the positioning hole 2 is concentric with the circular hole 28. Use the clamping device to press the box panel 27 against the flat plate 1. Next, place the nine threaded seats into the nine circular holes 28 of the box panel 27. The bottom wall of the threaded seat's welding portion 30 abuts the top wall of the flat plate 1, and the base 31 of the threaded seat is located in the positioning hole 2 of the flat plate 1, so that the box panel 27 and the welding portion 30 are on the same horizontal plane. The opening at the top of the positioning hole 2 is designed to be expanded outward to facilitate the insertion of the threaded seat base 31 into the positioning hole 2.

[0040] A first gap 32 is formed between the outer periphery of the welding portion 30 and the inner wall of the circular hole 28 of the box panel 27, and a second gap 33 is formed between the outer periphery of the base 31 and the inner wall of the positioning hole 2. The first gap 32 and the second gap 33 are used to adjust the position of the threaded seat so that the threaded seat and the circular hole 28 of the box panel 27 are concentric.

[0041] The threaded portion 29 of each threaded seat is covered with a positioning sleeve 3, the bottom wall of the positioning sleeve 3 abuts the top wall of the welding portion 30, and a locking member 4 is inserted into the positioning sleeve 3. The locking member 4 passes through the threaded seat and is threadedly installed in the flat plate 1. In this application, the locking member 4 can be a bolt.

[0042] After the threaded seat is concentrically adjusted with the circular hole 28 of the box panel 27, the positioning sleeve 3 is placed over the threaded portion 29, and the locking member 4 is rotated. The bottom end of the locking member 4 is screwed into the flat plate 1, thereby fixing the positioning sleeve 3, so that the positioning sleeve 3 presses down and fixes the welding portion 30 of the threaded seat. During the threaded seat welding process, the box panel 27 and the welding portion 30 can be stably located on the same horizontal plane. At the same time, the box panel 27 and the threaded seat are both fixed, making the threaded seat welding more stable and thus improving the accuracy of the threaded seat welding.

[0043] The flat plate 1 is provided with nine circular air supply grooves 5, corresponding one-to-one with the nine positioning holes 2. The circular air supply grooves 5 are located on the outer periphery of the positioning holes 2. The flat plate 1 is provided with a plurality of ventilation grooves 6, which are sequentially connected to the plurality of air supply grooves 5. An air inlet 7 is provided in the flat plate 1, which is connected to the ends of the ventilation grooves 6.

[0044] During threaded seat welding, the inlet pipe is precisely inserted into the inlet hole 7. Using the pressure from the gas supply equipment, argon gas is smoothly injected into the vent groove 6 along the inlet pipe. As the argon gas accumulates in the vent groove 6, it further fills the gas supply ring groove 5. This argon gas creates a stable inert gas protective atmosphere in the threaded seat welding area, effectively isolating active components such as oxygen from the air, thereby significantly improving the weld quality of the threaded seat.

[0045] The implementation principle of the anti-deformation welding tool for simultaneous welding of multiple threaded seats in Example 1 of the present application is as follows: when welding the threaded seat, first place the box panel 27 on the flat plate 1, and first place the welding part 30 into the circular hole 28. At this time, the bases 31 of the multiple threaded seats are located in the multiple positioning holes 2, so that the box panel 27 and the welding part 30 can be on the same horizontal plane, and then install the positioning sleeve 3 on the threaded cloth, and use the locking part 4 to fix the positioning sleeve 3. The positioning sleeve 3 presses the welding part 30 onto the flat plate 1, so that the threaded seat is more stable during welding, thereby improving the accuracy of the threaded seat welding.

[0046] Example 2:

[0047] Reference Figure 5 and Figure 6 The difference between Example 2 and Example 1 is that two stoppers 10 are fixedly mounted on two adjacent sides of the flat plate 1, and two movable grooves 15 are defined on the other adjacent sides of the flat plate 1. A push block 11 is slidably mounted within each movable groove 15. A first inclined wall 14 is formed on the side of the push block 11 and the baffle plate near the box panel 27. The first inclined wall 14 is inclined from top to bottom away from the box panel 27 and abuts the box panel 27.

[0048] A moving assembly 9 is installed in each moving groove 15 on the flat plate 1. The moving assembly 9 is used to drive the push block 11 to move toward or away from the box panel 27. Three guide rods 34 are fixedly installed on the flat plate 1. An L-shaped cross bar 12 is slidably installed on the three guide rods 34. The cross bar 12 is located above the four moving assemblies 9. A pressure block 35 is fixedly installed on the side wall of the cross bar 12. Two lifting members 13 are rotatably installed on the flat plate 1. The lifting members 13 are threaded through the cross bar 12 and are used to drive the cross bar 12 to move up and down. In this application, the lifting members 13 can be optionally used as screws.

[0049] When placing the box panel 27, first place the box panel 27 on the flat plate 1, then rotate the two lifting members 13 at the same time, and the two lifting members 13 drive the cross bar 12 to move downward. During the descent of the cross bar 12, it will first contact the four moving components 9, and then the cross bar 12 drives the push block 11 to move in the direction close to the box panel 27 with the help of the moving components 9. The push block 11 pushes the box panel 27 to move, so that it cooperates with the stop block 10 to abut and limit the four sides of the box panel 27. The first inclined wall 14 of the stop block 10 and the push block 11 abuts the box panel 27. Under the action of the first inclined wall 14, the stop block 10 and the push block 11 also have a downward pressing effect on the box panel 27. After completing the abutment on the four sides, the cross bar 12 continues to drive the pressure block 35 to move downward, and the pressure block 35 presses down on the box panel 27, and finally fixes the box panel 27 on the flat plate 1.

[0050] Specifically, the moving assembly 9 includes a moving block 91, a spring 92 and a tension spring 93. The moving block 91 is slidably installed in the moving groove 15. The moving block 91 is located on the side of the push block 11 away from the box panel 27. The moving block 91 is located below the cross bar 12, and the top wall of the moving block 91 and the bottom wall of the cross bar 12 are both formed with a second inclined wall 16. The tension spring 93 is installed in the moving groove 15 on the side of the moving block 91 away from the push block 11, and the two ends of the tension spring 93 are respectively fixedly connected to the inner wall of the moving groove 15 and the side wall of the moving block 91 away from the push block 11. The spring 92 is installed between the push block 11 and the moving block 91, and the two ends of the spring 92 are respectively fixedly connected to the side walls of the push block 11 and the moving block 91 that are close to each other.

[0051] When the crossbar 12 moves downward, the second inclined wall 16 at the bottom of the crossbar 12 contacts the second inclined wall 16 at the top of the moving block 91, pushing the moving block 91 toward the box panel 27. During this process, the moving block 91 stretches the tension spring 93 and simultaneously drives the push block 11 to move synchronously via the spring 92, ultimately causing the push block 11 to abut against the box panel 27. When the crossbar 12 moves upward, the second inclined wall 16 of the crossbar 12 disengages from the second inclined wall 16 of the moving block 91. The stretched tension spring 93 contracts and drives the moving block 91 back to its original position. The moving block 91 then drives the push block 11 in the opposite direction via the spring 92, separating the push block 11 from the box panel 27, thereby facilitating the removal of the box panel 27.

[0052] Reference Figure 6 and Figure 7 A driving block 19 is fixedly mounted on the bottom wall of the crossbar 12, and a rack 17 is slidably mounted in the horizontal direction in the flat plate 1. A third inclined wall 25 is formed at the ends of the driving block 19 and the rack 17 that are close to each other. A gear 18 is rotatably mounted in the flat plate 1, and the gear 18 meshes with the rack 17. A swivel 20 is rotatably mounted on the outside of each positioning hole 2 in the flat plate 1. The swivel 20 is coaxially mounted with the positioning hole 2. A first transmission belt 21 is sleeved on the rotating shaft of the gear 18 and one swivel 20, and a second transmission belt 22 is sleeved on each adjacent two swivels 20. Four shifting rods 23 are rotatably mounted on the top wall of each swivel 20 at equal intervals. The end of the shifting rod 23 away from the positioning hole 2 and connected to the swivel 20 is a telescopic end. The middle part of the shifting rod 23 is rotatably connected to the flat plate 1, and the four shifting rods 23 are arranged at equal intervals along the circumference of the positioning hole 2.

[0053] When the crossbar 12 moves downward, it drives the drive block 19 downward synchronously, and the third inclined wall 25 at the bottom of the drive block 19 contacts the third inclined wall 25 at the end of the rack 17. As the drive block 19 moves, it pushes the rack 17 horizontally, which in turn drives the gear 18 to rotate. Simultaneously, the rack 17 drives a rotating ring 20 via a first transmission belt 21. This rotating ring 20 then rotates the remaining rotating rings 20 synchronously via a second transmission belt 22. As the rotating ring 20 rotates, it drives the four levers 23 to rotate synchronously with it. These levers 23 rotate, shifting the base 31 of the threaded seat, ultimately precisely positioning the threaded seat in the center of the positioning hole 2.

[0054] A reset block 26 is fixedly mounted on the side wall of the rack 17, and an abutment block 36 is fixedly mounted within the flat panel 1. An elastic reset member 24 is mounted within the flat panel 1, with both ends of the elastic reset member 24 abutting against the reset block 26 and the abutment block 36. In the present application, the reset elastic member 24 may be a spring. When the crossbar 12 moves downward and drives the rack 17, the rack 17 drives the reset block 26 to move, and the elastic reset member 24 contracts and deforms after being squeezed by the reset block 26. When the crossbar 12 moves upward, the elastic reset member 24 pushes the rack 17 to move and reset via the reset block 26, thereby driving the shift lever 23 to rotate and reset.

[0055] The implementation principle of Example 2 of the present application is as follows: first, the box panel 27 is placed on the flat plate 1, and multiple threaded seats are placed into the multiple positioning holes 2 of the flat plate 1. Then, the two lifting members 13 are rotated simultaneously, and the two lifting members 13 drive the crossbar 12 to move downward. During the descent of the crossbar 12, it will first contact the four moving components 9. Then, the crossbar 12 drives the push block 11 to move toward the box panel 27 with the help of the moving components 9. The push block 11 pushes the box panel 27 to move, so that it cooperates with the stop block 10 to abut and limit the four sides of the box panel 27. The first inclined wall 14 of the stop block 10 and the push block 11 abuts the box panel 27. Under the action of the first inclined wall 14, the stop block 10 and the push block 11 also have a downward pressure on the box panel 27. After the four sides are abutted, the crossbar 12 continues to drive the pressing block 35 to move downward, and the pressing block 35 presses down on the box panel 27, finally fixing the box panel 27 on the flat plate 1. When the crossbar 12 moves downward, it drives the drive block 19 to descend synchronously, and the third inclined wall 25 at the bottom of the drive block 19 contacts the third inclined wall 25 at the end of the rack 17. The drive block 19 pushes the rack 17 to move horizontally during movement, and the rack 17 in turn drives the gear 18 to rotate. At the same time, the rack 17 drives a swivel 20 to rotate through the first transmission belt 21, and the swivel 20 then drives the remaining swivels 20 to rotate synchronously through the second transmission belt 22. During the rotation of the swivel 20, the four levers 23 are driven to rotate synchronously with it. After the four levers 23 rotate, they move the base 31 of the threaded seat, and finally accurately position the threaded seat to the middle of the positioning hole 2, so that the box panel 27 can be fixed while the threaded seat can be centered, which increases the accuracy of the threaded seat welding.

[0056] The above are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
