[0036] The embodiments of the present application disclose an anti-deformation welding tool for simultaneous welding of multiple-piece threaded seats.

[0037] Embodiment 1

[0038] With reference to Figs. 1-9, Figure 1 Figure 2 Figure 3 and Figure 4 An anti-deformation welding tool for simultaneous welding of multiple-piece threaded seats comprises a flat plate 1, which is rectangular, and a sealing gasket 8 fixedly installed on the top wall of the flat plate 1, the sealing gasket 8 being a long rectangular ring and located on the outer circumferential side of the flat plate 1. A box panel 27 is rectangular, nine circular holes 28 are formed in the box panel 27, 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 flat plate 1. Nine positioning holes 2 are formed on the upper surface of the flat plate 1, and the nine positioning holes 2 correspond to the nine circular holes 28 one by one.

[0039] ​​First, the box panel 27 is placed on the flat plate 1, and the flat plate 1 is adjusted so that the positioning hole 2 is concentric with the circular hole 28, and the box panel 27 is pressed on the flat plate 1 using a pressing device. Then, nine threaded seats are placed in the nine circular holes 28 of the box panel 27, the bottom wall of the welding part 30 of the threaded seat abuts against 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 part 30 can be in the same horizontal plane. The opening at the top of the positioning hole 2 is expanded outward to facilitate the insertion of the base 31 of the threaded seat into the positioning hole 2.

[0040] There is a first gap 32 between the outer circumferential side of the welding part 30 and the inner wall of the circular hole 28 of the box panel 27, and a second gap 33 between the outer circumferential side of the base 31 and the inner wall of the positioning hole 2. The position of the threaded seat is adjusted through the first gap 32 and the second gap 33, so that the threaded seat is concentric with the circular hole 28 of the box panel 27.

[0041] A positioning sleeve 3 is provided on the threaded part 29 of each threaded seat, the bottom wall of the positioning sleeve 3 abuts against the top wall of the welding part 30, and a locking piece 4 is provided in the positioning sleeve 3, which passes through the threaded seat and is screwed into the flat plate 1. In this application, the locking piece 4 can be selected as a bolt.

[0042] After the threaded seat is adjusted concentrically with the circular hole 28 of the box panel 27, the positioning sleeve 3 is provided on the threaded part 29, and then the locking piece 4 is rotated and screwed into the flat plate 1 at the bottom end, thereby fixing the positioning sleeve 3 and pressing the welding part 30 of the threaded seat. During the welding of the threaded seat, the box panel 27 and the welding part 30 can be stably in the same horizontal plane, and the box panel 27 and the threaded seat are both fixed, so that the threaded seat is more stable during welding, thereby improving the precision of the threaded seat welding.

[0043] Nine gas supply ring grooves 5 are provided on the flat plate 1, and the nine gas supply ring grooves 5 correspond one-to-one to the nine positioning holes 2. The gas supply ring grooves 5 are circular and located on the outer circumferential side of the positioning hole 2. A plurality of air passages 6 are provided on the flat plate 1, and the plurality of air passages 6 are sequentially connected to the plurality of gas supply ring grooves 5. An air inlet hole 7 is provided in the flat plate 1, and the air inlet hole 7 is in communication with the end of the air passage 6.

[0044] During the threaded seat welding operation, the air inlet pipe is accurately inserted into the air inlet hole 7, and the argon gas is smoothly injected into the air passage 6 by the pressure drive of the gas supply equipment. With the accumulation of argon gas in the air passage 6, it will further fill the gas supply ring groove 5. The argon gas forms a stable inert gas protection atmosphere in the threaded seat welding area, effectively isolating active ingredients such as oxygen in the air, thereby significantly improving the welding quality of the threaded seat.

[0045] The implementation principle of the anti-deformation welding tool for simultaneously welding multiple threaded seats according to the embodiment 1 of the present application is as follows: when the threaded seats are welded, the box panel 27 is first placed on the flat plate 1, and the welding part 30 is first placed into the round 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, then the positioning sleeve 3 is installed on the threaded cloth, the positioning sleeve 3 is fixed by using the locking part 4, and the welding part 30 is pressed tightly on the flat plate 1 by the positioning sleeve 3, so that the threaded seats are more stable during welding, and the precision of the threaded seat welding is improved.

[0046] Embodiment 2

[0047] With reference to Figure 5 and Figure 6 The difference between the embodiment 2 and the embodiment 1 of the present application is that two stop blocks 10 are fixedly installed on each of the two adjacent sides of the flat plate 1, two moving grooves 15 are formed on each of the other two adjacent sides of the flat plate 1, and a push block 11 is slidingly installed in each of the moving grooves 15. The push block 11 and the side of the baffle close to the box panel 27 are formed with a first inclined wall 14, the first inclined wall 14 is inclined from top to bottom away from the box panel 27, and the first inclined wall 14 abuts against the box panel 27.

[0048] A moving assembly 9 is installed on the flat plate 1 in each of the moving grooves 15, and the moving assembly 9 is used to drive the push block 11 to move towards 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 slidingly installed on the three guide rods 34, the cross bar 12 is located above the four moving assemblies 9, and a pressing block 35 is fixedly installed on the side wall of the cross bar 12. Two lifting parts 13 are rotatably installed on the flat plate 1, the lifting parts 13 are screwed through the cross bar 12 and are used to drive the cross bar 12 to move up and down. In the present application, the lifting part 13 can be selected as a screw rod.

[0049] When the box panel 27 is placed, the box panel 27 is first placed on the flat plate 1, and then the two lifting parts 13 are simultaneously rotated, and the two lifting parts 13 drive the cross bar 12 to move downward. In the process of the cross bar 12 descending, the cross bar 12 first contacts the four moving assemblies 9, and then the cross bar 12 drives the push block 11 to move towards the box panel 27 by means of the moving assembly 9. The push block 11 pushes the box panel 27 to move, so that the box panel 27 is limited and positioned by the stop block 10. The first inclined wall 14 of the stop block 10 and the push block 11 abuts against the box panel 27, and the stop block 10 and the push block 11 also have a downward pressing action on the box panel 27 under the action of the first inclined wall 14. After the four edges are limited and positioned, the cross bar 12 continues to drive the pressing block 35 to move downward, the pressing block 35 presses the box panel 27 downward, and finally the box panel 27 is fixed on the flat plate 1.

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

[0051] When the horizontal rod 12 moves downward, the second inclined wall 16 at the bottom of the horizontal rod 12 will contact the second inclined wall 16 at the top of the moving block 91 and push the moving block 91 to move towards the cabinet panel 27. In this process, the moving block 91 will stretch the tension spring 93, and at the same time, the push block 11 will be synchronously moved by the spring 92, so that the push block 11 is finally abutted against the cabinet panel 27. When the horizontal rod 12 moves upward, the second inclined wall 16 of the horizontal rod 12 is disengaged from the second inclined wall 16 of the moving block 91. The stretched tension spring 93 will contract and drive the moving block 91 to reset. The moving block 91 drives the push block 11 to move in the reverse direction through the spring 92, so that the push block 11 is separated from the cabinet panel 27, thereby facilitating the removal of the cabinet panel 27.

[0052] With reference to Figure 6 and Figure 7 , a driving block 19 is fixedly installed on the bottom wall of the horizontal rod 12, and a rack 17 is slidingly installed in the horizontal direction in the flat plate 1. The end portions of the driving block 19 and the rack 17 close to each other are both formed with a third inclined wall 25. A gear 18 is rotationally installed in the flat plate 1 and engaged with the rack 17. A rotating ring 20 is rotationally installed in the flat plate 1 outside each positioning hole 2, and the rotating ring 20 is coaxially installed with the positioning hole 2. A first transmission belt 21 is sleeved on the rotating shaft of the gear 18 and one rotating ring 20. A second transmission belt 22 is sleeved on every adjacent two rotating rings 20. Four lever rods 23 are rotationally installed on the top wall of each rotating ring 20 at equal intervals. The end portion of the lever rod 23 away from the positioning hole 2 and connected with the rotating ring 20 is a telescopic end. The middle portion of the lever rod 23 is rotationally connected with the flat plate 1, and the four lever rods 23 are arranged at equal intervals along the circumferential direction of the positioning hole 2.

[0053] When the horizontal rod 12 moves downward, the driving block 19 is synchronously lowered, and the third inclined wall 25 at the bottom of the driving block 19 is in contact with the third inclined wall 25 at the end of the rack 17. The driving block 19 pushes the rack 17 to move horizontally in the movement, and the rack 17 in turn drives the gear 18 to rotate. At the same time, the rack 17 drives a rotating ring 20 to rotate through the first transmission belt 21, and the rotating ring 20 in turn synchronously rotates the remaining rotating rings 20 through the second transmission belt 22. In the rotating process of the rotating ring 20, four shift rods 23 are synchronously rotated, and the four shift rods 23 rotate to shift the base 31 of the threaded seat, and finally accurately position the threaded seat to the middle of the positioning hole 2.

[0054] The side wall of the rack 17 is fixedly installed with a reset block 26, the flat plate 1 is fixedly installed with an abutting block 36, and the flat plate 1 is installed with an elastic reset member 24, the two ends of the elastic reset member 24 abutting the reset block 26 and the abutting block 36. In this application, the reset elastic member 24 can be selected as a spring. When the horizontal rod 12 moves downward and drives the rack 17 to move, the rack 17 drives the reset block 26 to move, and the elastic reset member 24 is extruded by the reset block 26 and shrinks and deforms. When the horizontal rod 12 moves upward, the elastic reset member 24 pushes the rack 17 to move through the reset block 26, and in turn drives the shift rod 23 to rotate and reset.

[0055] The implementation principle of the embodiment 2 of the present application is as follows: first, the box panel 27 is placed on the flat plate 1, the plurality of threaded seats are placed into the plurality of positioning holes 2 of the flat plate 1, then the two lifting members 13 are simultaneously rotated, and the two lifting members 13 drive the horizontal rod 12 to move downward. During the descending process of the horizontal rod 12, the horizontal rod 12 first contacts the four moving assemblies 9, and then the horizontal rod 12 drives the push block 11 to move towards the direction of being close to the box panel 27 by means of the moving assemblies 9. The push block 11 pushes the box panel 27 to move, so that the box panel 27 is limited and positioned by the stop block 10 on four sides. The first inclined wall 14 of the stop block 10 and the push block 11 abuts against the box panel 27, and the stop block 10 and the push block 11 also have a downward pressing action on the box panel 27 under the action of the first inclined wall 14. After the four sides are abutted, the horizontal rod 12 continues to drive the pressing block 35 to move downward, and the pressing block 35 presses the box panel 27 downward, so that the box panel 27 is finally fixed on the flat plate 1. When the horizontal rod 12 moves downward, the driving block 19 is synchronously lowered, and the third inclined wall 25 at the bottom of the driving block 19 contacts the third inclined wall 25 at the end of the rack 17. The driving block 19 pushes the rack 17 to move horizontally during the movement, and the rack 17 in turn drives the gear 18 to rotate. At the same time, the rack 17 drives one rotating ring 20 to rotate through the first transmission belt 21, and the remaining rotating rings 20 are synchronously rotated through the second transmission belt 22. During the rotating process of the rotating ring 20, the four lever rods 23 are synchronously rotated with the rotating ring 20, and the four lever rods 23 rotate to push the bases 31 of the threaded seats, so that the threaded seats are finally accurately positioned in the middle of the positioning holes 2, thereby being able to fix the box panel 27 and also being able to center the threaded seats, and the accuracy of the threaded seat welding is increased.

[0056] The above is only an optional embodiment of the present disclosure, and is not used to limit the present disclosure. The present disclosure can have various modifications and changes for those skilled in the art.
