Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to a welding device for valves. Background Art

[0002] Socket welding is to insert the pipe into the valve body for welding. The socket welding connection is mainly used for small-diameter valves and pipes. Small-diameter pipes generally have thin walls, are prone to misalignment and ablation, and are difficult to weld, so they are more suitable for socket welding.

[0003] When workers perform socket welding on small valves, due to the lack of a special welding platform, they usually weld the iron rod to a fixed object, then insert one end of the valve on the iron rod, insert the pipe fitting to be welded into the other end of the valve, and finally use a welding gun to weld the valve and the pipe fitting.

[0004] This welding method is inconvenient and will affect the quality of welding. Therefore, a device that can assist workers in performing socket welding is needed to avoid the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a welding device for a valve in order to solve the above-mentioned problem.

The height of the connecting plate is controlled by the adjusting member so that the rotating block abuts against the end of the pipe to be welded, and the insert block is inserted into the pipe.

[0007] Preferably, the adjusting member includes a fixed disk 1 fixedly connected to the vertical rod 1, a fixed disk 2 corresponding to the fixed disk 1 is fixed on the vertical rod 2, a plurality of circumferentially distributed through holes 1 are provided on the fixed disk 1, a through hole 2 corresponding to the position of the through hole 1 is provided on the fixed disk 2, a rotating ring is slidably connected to the vertical rod 2, and a through rod passing through the through holes 1 and 2 is fixed on the rotating ring, the rotating ring cooperates with the mating member to rotate the driven wheel, thereby driving the valve to rotate together.

[0008] Preferably, the mating part includes a long rod rotatably connected to the base, a driving wheel meshing with the driven wheel through a gear is fixed on the long rod, a sliding groove is provided on the long rod, and the long rod is slidably connected to gear 2, a sliding block slidably connected to the sliding groove is fixed on the gear 2, an annular sleeve is fixed on the sliding block, and the annular sleeve is slidably connected to the long rod, the annular sleeve is rotatably connected to a cross plate, and the cross plate is rotatably connected to a rotating ring, a circular hole slidably connected to the long rod is provided on the connecting plate, and a limiter for limiting the position of the cross plate is also provided on the long rod.

[0009] Preferably, the limiting member includes a stop block fixed on the long rod, a spring is sleeved on the long rod, one end of the spring abuts against the stop block, and the other end abuts against the bottom of the cross plate, and the elastic force of the spring pushes the cross plate up until gear two is meshed with gear one through the gears.

[0010] Preferably, the horizontal plate is pressed downward until the through rod at the bottom of the rotating ring passes through through hole 2 and through hole 1. At this time, gear 2 moves downward with the horizontal plate, so gear 2 does not mesh with gear 1, and vertical rod 2 drives vertical rod 1 to rotate during rotation.

[0011] Preferably, the screw block is connected to the screw groove by threads and moves upward, and when the screw block abuts against the inner top wall of the screw groove, the long rod is separated from the circular hole, and the gear 2 can be removed from the long rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present application enables the horizontal plate to move up under the elastic force of the spring, causing gear 2 to mesh with gear 1. Therefore, when no force is applied to the horizontal plate, gear 2 can always remain in mesh with gear 1. When the handle is rotated, the top plate can be driven to rotate, so the valve and the pipe fitting can rotate accordingly, which is convenient for welding operations. When the through rod passes through through hole 1 and through hole 2, the handle can also be used to control the rotation of vertical rod 1, thereby changing the height of the connecting plate, so that the connecting plate can cooperate with the rotating block to press one end of the pipe fitting.

The pipe fitting to be welded is inserted into the valve body from the other end opening of the valve. During the rotation of the vertical rod, the connecting plate can be moved downward, thereby causing the rotating block to abut against the top of the pipe fitting. With the cooperation of the top plate and the rotating block, the valve and the pipe fitting are clamped and fixed, and the staff can use a welding gun to perform welding operations on the connection between the valve and the pipe fitting.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 4 , the present invention provides a technical solution: A welding device for a valve, comprising: A base 1, a driven wheel 2 is rotatably connected to the base 1, and a top plate 3 is fixed to the driven wheel 2, a clamping block 4 inserted into the valve body is fixed to the top plate 3, and the clamping block 4 extends into an opening at one end of the valve body, and the other end of the valve body is opened upwards for plugging with a pipe fitting to be welded; The base 1 is provided with a placement groove 32, and a bottom groove 33 and a wire groove 34 are provided at the placement groove 32. A welding gun 35 is placed at the placement groove 32, and the tail of the welding gun 35 extends into the bottom groove 33, and the wire of the welding gun 35 extends into the wire groove 34. This is a direct reference to the prior art and will not be described in detail here. A fixing seat 5, a screw groove 6 and a connecting hole 7 are provided on the fixing seat 5, and the screw groove 6 is connected to a screw block 8 by a thread, a vertical rod 9 slidably connected to the connecting hole 7 is fixed on the screw block 8, the vertical rod 9 is rotatably connected to a vertical rod 2 12, a gear 15 is fixed on the vertical rod 2 12, the gear 15 is fixedly connected to a handle 17, and the handle 17 is rotatably connected to a connecting plate 16, and the gear 15 and the vertical rod 2 12 can be rotated together by rotating the handle 17; The rotating block 18 is rotatably connected to the connecting plate 16, and an insert block 19 is fixed to the bottom of the rotating block 18. The height of the connecting plate 16 is controlled by the adjusting member so that the rotating block 18 abuts against the end of the pipe to be welded, and the insert block 19 is inserted into the pipe.

[0018] Specifically, Figure 1 As shown, the adjusting member includes a fixed plate 10 fixedly connected to the vertical rod 19, a fixed plate 2 13 corresponding to the fixed plate 10 is fixed on the vertical rod 2 12, a plurality of through holes 11 distributed circumferentially are provided on the fixed plate 10, a through hole 2 14 corresponding to the position of the through hole 11 is provided on the fixed plate 2 13, a rotating ring 20 is slidably connected to the vertical rod 2 12, and a through rod 21 penetrating through the through hole 11 and the through hole 2 14 is fixed on the rotating ring 20, and the rotating ring 20 cooperates with the matching member to make the driven wheel 2 rotate, thereby driving the valve to rotate together. After the through rod 21 penetrates through the through hole 11 and the through hole 2 14, the vertical rod 19 and the vertical rod 2 12 can be fixed as one body, so the vertical rod 2 12 will also drive the vertical rod 19 to rotate when rotating. Therefore, the staff can rotate the handle 17 to rotate the vertical rod 2 12, thereby changing the height of the vertical rod 19 and the vertical rod 2 12, so that the connecting plate 16 can abut against the pipe fitting on the valve.

[0019] Specifically, Figure 3 As shown, the matching part includes a long rod 27 rotatably connected to the base 1, a driving wheel 26 meshing with the driven wheel 2 through a gear is fixed on the long rod 27, a sliding groove 28 is provided on the long rod 27, and the long rod 27 is slidably connected to the gear 2 24, a slider 25 slidably connected to the sliding groove 28 is fixed on the gear 24, an annular sleeve 23 is fixed on the slider 25, and the annular sleeve 23 is slidably connected to the long rod 27, the annular sleeve 23 is rotatably connected to the cross plate 22, and the cross plate 22 is rotatably connected to the rotating ring 20, a circular hole 31 slidably connected to the long rod 27 is provided on the connecting plate 16, and a limiter for limiting the position of the cross plate 22 is also provided on the long rod 27.

[0020] Specifically, Figure 2 and Figure 3 As shown, the limiter includes a stopper 29 fixed on the long rod 27, and a spring 30 is sleeved on the long rod 27, and one end of the spring 30 abuts against the stopper 29, and the other end abuts against the bottom of the horizontal plate 22. The elastic force of the spring 30 pushes the horizontal plate 22 to move up until the gear 24 and the gear 1 15 are meshed through the gears. The horizontal plate 22 is pressed down until the through rod 21 at the bottom of the rotating ring 20 passes through the through hole 2 14 and the through hole 1 11. At this time, the gear 24 moves down with the horizontal plate 22, so the gear 24 does not mesh with the gear 1 15, and the vertical rod 2 12 drives the vertical rod 1 9 to rotate during rotation.

[0021] The screw block 8 and the screw groove 6 are connected by threads and moved upward. When the screw block 8 abuts against the inner top wall of the screw groove 6, the long rod 27 is separated from the circular hole 31. At this time, the gear 24 can be removed from the long rod 27, so it is more convenient to replace and clean the gear 24. An elastic rubber gasket protrudes from the part where the screw block 8 abuts against the inner top wall of the screw groove 6, so there will be no wear when the screw block 8 abuts against the inner wall of the screw groove 6.

[0022] In summary, the valve installation process provided in this embodiment is as follows: Put the open end of the valve on the clamping block 4, and the valve is in contact with the top plate 3. Then insert the pipe to be welded into the valve body from the other end of the valve. Rotate the connecting plate 16 so that the rotating block 18 and the inserting block 19 on the connecting plate 16 are aligned with the pipe to be welded.

[0023] Press the horizontal plate 22 downward, so that the horizontal plate 22 moves down to the point where the gear 2 24 is not meshed with the gear 1 15, and the through rod 21 passes through the through hole 1 11 and the through hole 2 14. At this time, the handle 17 can be rotated, and the handle 17 will drive the gear 15 and the vertical rod 2 12 to rotate during the rotation. Since the through rod 21 passes through the through hole 1 11 and the through hole 2 14, the vertical rod 2 12 will also drive the vertical rod 1 9 to rotate when it rotates, so the screw block 8 moves down at the screw groove 6 during the rotation. Then the connecting plate 16 also moves down in the vertical direction, and the long rod 27 is also slidably connected with the circular hole 31, until the rotating block 18 on the connecting plate 16 abuts against the top of the pipe to be welded, and the insert block 19 extends into the pipe to be welded.

[0024] At this time, with the cooperation of the rotating block 18 and the top plate 3, the valve and the pipe fitting are fixed as one, which is convenient for welding. Then, the downward pressure on the horizontal plate 22 can be released, and the horizontal plate 22 moves upward under the elastic force of the spring 30 until the gear 24 is engaged with the gear 1 15, and the through rod 21 is separated from the through hole 11 and the through hole 2 14.

[0025] At this time, the vertical rod 2 12 will not drive the vertical rod 1 9 to rotate when rotating.

[0026] Welding process: Remove the welding gun 35 from the groove 32, and use the welding gun 35 to weld the connection between the valve and the pipe fitting. When the valve and the pipe fitting need to be rotated: By turning the handle 17, the gear 1 15 rotates. Since the gear 2 24 is meshed with the gear 1 15, the gear 1 15 rotates and the gear 2 24 rotates. Since the slider 25 on the gear 2 24 is slidably connected with the slide groove 28 provided on the long rod 27, the gear 2 24 rotates and drives the long rod 27 to rotate.

[0027] Since the driving wheel 26 at the bottom of the long rod 27 is meshed with the driven wheel 2, the long rod 27 will cause the driven wheel 2 to rotate together, thereby driving the top plate 3 to rotate. Since the valve and the pipe fitting are fixed by the clamping of the top plate 3 and the rotating block 18, the rotation of the top plate 3 will drive the valve and the pipe fitting to rotate together. The staff can rotate the handle 17 to rotate the valve and the pipe fitting, and use the welding gun 35 to weld the valve and the pipe fitting together.

[0028] After welding is completed, the horizontal plate 22 can be pushed downward so that the horizontal plate 22 and the gear 2 24 move downward together until the through rod 21 passes through the through hole 11 and the through hole 2 14. By turning the handle 17, the vertical rod 1 9 and the vertical rod 2 12 rotate together until the connecting plate 16 moves up and the plug block 19 is disengaged from the inside of the pipe fitting. The connecting plate 16 can be rotated, and finally the valve and the pipe fitting can be removed from the top plate 3.

[0029] Another way to operate: Under the elastic force of the spring 30, the horizontal plate 22 can be moved upward, causing the gear 24 to mesh with the gear 1 15. Therefore, when no force is applied to the horizontal plate 22, the gear 24 can always remain meshed with the gear 1 15. When the handle 17 is rotated, the top plate 3 can be driven to rotate, so the valve and the pipe fitting can rotate accordingly, which is convenient for welding operations.

[0030] If you want to adjust the height of the connecting plate 16, you can directly rotate the vertical rod 9, so that the height of the connecting plate 16 directly changes.

[0031] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
