[0017] The welding method of a kind of automatic positioning welding tooling for sheet metal parts includes the following steps:

[0018] S1: When the power device moves, it drives the rotating shaft to move in the direction of approaching each other. When the power device moves, it squeezes the limit spring. When the limit spring is squeezed, it contracts in the direction of approaching each other. When the limit spring contracts in place, it limits the power device to prevent the power device from contacting the support ring;

[0019] S2: When the positioning ring expands, it supports the tubular sheet metal part and fixes the sheet metal part for positioning. When the sheet metal part is supported, the surface of the pulley contacts the sheet metal part. When the ends of the two sheet metal parts contact, the motor is turned off to keep it stationary, effectively positioning the sheet metal part. And the surface of the positioning ring and the inner wall of the sheet metal part support and fix it, replacing the cumbersome operation steps and improving the welding efficiency;

[0020] S3: When the passive rod moves, it pushes the lower slide plate to slide down along the inner wall of the chute. When the lower slide plate slides, it drives the push rod to move downward. When the push rod moves, it pushes the blocking cover to move in the direction of approaching each other. When the blocking cover moves, it wraps the automatic welding machine, which can block the welding slag generated during the welding process and also isolate the arc light generated during welding to prevent harm to the eyes of the staff;

[0021] S4: When the blocking cover moves, it pulls the support telescopic rod to extend in the direction of approaching each other. When the blocking cover moves, it drives the material receiving plate to move in the direction of approaching each other. At this time, the ends of the two material receiving plates will contact. At this time, the material receiving plate is directly below the blocking cover. The welding slag blocked by the blocking cover will fall on the surface of the material receiving plate, thus achieving the effect of collecting the welding slag and saving the labor of the staff.

[0022] The present invention has the following beneficial effects:

[0023] In the present invention, by providing a positioning mechanism, first, the tubular sheet metal parts to be welded are placed on the surface of the positioning ring, and then the motor is started to drive the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, the threaded rings will move towards each other. When the threaded rings move, they will drive the positioning tables to move towards each other. When the positioning tables move, they will drive the moving plates to slide towards each other on the surface of the guide rails. When the positioning tables move, they will drive the power devices to move towards each other. When the power devices move, they will drive the rotating shafts to move towards each other. When the power devices move, they will squeeze the limiting springs. When the limiting springs are squeezed, they will contract towards each other. When the limiting springs are contracted in place, they will limit the power devices to prevent the power devices from contacting the support ring. When the rotating shafts move, they will drive the grooves to move towards each other. At this time, due to the support of the pull rods, the sliding rings remain stationary, and the fixed rings will move together with the rotating shafts and push the push plates to move away from each other. When the push plates move, they will push the positioning rings to expand away from each other. When the positioning rings expand, they will support the tubular sheet metal parts and fix the sheet metal parts in place for positioning. When the sheet metal parts are supported, the surfaces of the pulleys will contact the sheet metal parts. When the ends of the two sheet metal parts contact, the motor is turned off to keep them stationary, effectively positioning the sheet metal parts. And by the surface of the positioning ring and the inner wall of the sheet metal parts, it is supported and fixed, replacing the cumbersome operation steps and improving the welding efficiency.

[0024] In the present invention, by providing a stabilizing mechanism, when the positioning table moves, it will push the right-angle frame to move towards each other. When the right-angle frame moves, it will push the sliding plate to move towards each other along the inner wall of the chute plate. When the sliding plate moves, it will push the lower push plate to move downwards. When the lower push plate moves, it will push the driven plate to move downwards. When the driven plate moves, it will drive the automatic welding machine to move downwards. When the automatic welding machine moves to the joint of the two sheet metal parts and remains stationary, then the automatic welding machine is started to start welding. At the same time, the power device is started to drive the rotating shaft to rotate. When the rotating shaft rotates, it will drive the slip ring to rotate. When the slip ring rotates, it will drive the push plate to rotate. When the slip ring rotates, it will drive the positioning ring to rotate. When the positioning ring rotates, it will drive the sheet metal part to rotate, so as to weld the sheet metal part and weld the two sheet metal parts together. When the driven plate moves downwards, it will drive the reinforcement ring to move downwards. When the rotating wheel contacts the sheet metal part, it will squeeze the contact elastic frame backwards. When the contact elastic frame is squeezed, it will push the extension ring to extend in a circular direction away from each other along the inner wall of the extension groove. When the welding is completed, the motor drives the bidirectional threaded rod to reverse. When the bidirectional threaded rod reverses, the two positioning tables will move away from each other. When the positioning tables move, it will drive the whole rotating shaft to move. When the two positioning rings on both sides move away from each other, they will gradually separate from the welded workpiece. When the positioning ring separates from the sheet metal part, it will fall on the surface of the receiving table, thus preventing the sheet metal part from falling and facilitating the staff to pick it up, effectively strengthening the sheet metal part and making the sheet metal part more stable during the welding process.

[0025] In the present invention, by providing a receiving mechanism, when the driven plate moves downwards, it will drive the passive rod to move downwards. When the passive rod moves, it will push the lower sliding plate to slide downwards along the inner wall of the chute. When the lower sliding plate slides, it will drive the push rod to move downwards. When the push rod moves, it will push the blocking cover to move towards each other. When the blocking cover moves, it will wrap the automatic welding machine, which can block the welding slag generated during the welding process and can also isolate the arc light generated during welding to prevent harm to the eyes of the staff. When the blocking cover moves, it will pull the support telescopic rod to extend towards each other. When the blocking cover moves, it will drive the receiving plate to move towards each other. At this time, the ends of the two receiving plates will contact. At this time, the receiving plate is directly below the blocking cover. The welding slag blocked by the blocking cover will fall on the surface of the receiving plate, thus achieving the effect of collecting the welding slag and saving the labor of the staff.

[0026] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] A positioning mechanism 10. The positioning mechanism 10 includes a slip ring 16. A push plate 17 is rotatably connected to the surface of the slip ring 16. When the rotating shaft 13 moves, it will drive the grooves to move towards each other. At this time, due to the support of the pull rod 21, the slip ring 16 remains stationary.

When the slip ring 16 rotates, it will drive the rotation of the positioning ring 18. When the positioning ring 18 rotates, it will drive the rotation of the sheet metal part, so as to weld the sheet metal part and weld two sheet metal parts together. When the driven plate 35 moves downward, it will drive the reinforcing ring 37 to move downward. An extension groove is formed on the surface of the reinforcing ring 37, and an extension ring 38 is slidably connected to the inner wall of the extension groove.

[0045] The material receiving mechanism 50 includes a blocking cover 54. When the push rod 53 moves, it will push the blocking cover 54 to move in a direction close to each other. A material receiving plate 55 is fixedly connected to the bottom of the blocking cover 54. When the blocking cover 54 moves, it will drive the material receiving plate 55 to move in a direction close to each other. At this time, the ends of the two material receiving plates 55 will contact. A support telescopic rod 56 is fixedly connected to the surface of the blocking cover 54. When the blocking cover 54 moves, it will wrap the automatic welding machine 36, which can block the welding slag generated during the welding process and can also isolate the arc light generated during welding to prevent harm to the eyes of the staff. When the blocking cover 54 moves, it will pull the support telescopic rod 56 to extend in a direction close to each other.

[0046] One end of the bidirectional threaded rod 5 away from the motor 4 is rotatably connected to the surface of the workbench 1.

[0047] The positioning mechanism 10 includes a positioning table 11. First, place the cylindrical sheet metal part to be welded on the surface of the positioning ring 18, and then start the motor 4 to drive the bidirectional threaded rod 5 to rotate. When the bidirectional threaded rod 5 rotates, the threaded rings 6 will move towards each other. When the threaded rings 6 move, they will drive the positioning table 11 to move towards each other. A power device 12 is fixedly connected to the surface of the positioning table 11. When the positioning table 11 moves, it will drive the power device 12 to move towards each other. The output end of the power device 12 is fixedly connected to a rotating shaft 13. When the power device 12 moves, it will drive the rotating shaft 13 to move towards each other.

A pull rod 21 is slidably connected to the inner wall of the support ring 20. A pulley 22 is rotatably connected to the inner wall of the positioning ring 18. When the sheet metal part is supported, the surface of the pulley 22 will contact the sheet metal part. When the ends of the two sheet metal parts come into contact, turn off the motor 4 to keep it stationary, effectively position the sheet metal part, and support and fix it through the surface of the positioning ring 18 and the inner wall of the sheet metal part, replacing the cumbersome operation steps and improving the welding efficiency.

[0048] The bottom of the positioning table 11 is fixedly connected to the surface of the moving plate 3. When the positioning table 11 moves, it will drive the moving plate 3 to slide towards each other on the surface of the guide rail 2. One end of the threaded ring 6 away from the bidirectional threaded rod 5 is fixedly connected to the surface of the positioning table 11. One end of the limiting spring 14 away from the power device 12 is fixedly connected to the surface of the support ring 20. When the power device 12 moves, it will squeeze the limiting spring 14. When the limiting spring 14 is squeezed, it will contract towards each other. When the limiting spring 14 contracts in place, it will limit the power device 12 to prevent the power device 12 from contacting the support ring 20. The bottom of the support ring 20 is fixedly connected to the surface of the workbench 1. The inner wall of the rotating disc 15 is fixedly connected to the surface of the rotating shaft 13.

One end of the lower push plate 34 away from the sliding plate 32 is rotatably connected to a driven plate 35. An automatic welding machine 36 is fixedly connected to the surface of the driven plate 35. When the driven plate 35 moves, it will drive the automatic welding machine 36 to move downward. When the automatic welding machine 36 moves to the joint of the two sheet metals and remains stationary, then the automatic welding machine 36 is started to start welding. The end of the extension ring 38 is fixedly connected to a contact elastic frame 39. A runner 40 is rotatably connected to the surface of the contact elastic frame 39. When the welding is completed, the motor 4 drives the bidirectional threaded rod 5 to reverse. When the bidirectional threaded rod 5 reverses, it will cause the two positioning tables 11 to move away from each other. When the positioning table 11 moves, it will drive the entire rotating shaft 13 to move. When the two positioning rings 18 move away from each other, they will gradually separate from the welded workpiece. When the positioning ring 18 separates from the sheet metal, it will fall on the surface of the material receiving table 8, thereby preventing the sheet metal from falling and facilitating the staff to take it, effectively strengthening the sheet metal and making the sheet metal more stable during the welding process.

[0050] One end of the right-angle frame 33 away from the sliding plate 32 is fixedly connected to the top of the positioning table 11. When the right-angle frame 33 moves, it will push the sliding plate 32 to move towards each other on the inner wall of the chute plate 31. The top of the chute plate 31 is fixedly connected to the top of the inner wall of the U-shaped frame 7. Both ends of the driven plate 35 are fixedly connected to the surface of the reinforcement ring 37. When the lower push plate 34 moves, it will push the driven plate 35 to move downward. At this time, the material receiving plate 55 is located directly below the blocking cover 54. The welding slag blocked by the blocking cover 54 will fall on the surface of the material receiving plate 55, thereby achieving the effect of collecting the welding slag and saving the labor of the staff.

[0051] The material receiving mechanism 50 includes a passive rod 51. When the driven plate 35 moves downward, it will drive the passive rod 51 to move downward. One end of the passive rod 51 is fixedly connected to a lower sliding plate 52. When the passive rod 51 moves, it will push the lower sliding plate 52 to slide downward on the inner wall of the chute.

[0052] One end of the passive rod 51 away from the lower sliding plate 52 is fixedly connected to the surface of the driven plate 35. One end of the push rod 53 away from the lower sliding plate 52 is rotatably connected to the surface of the blocking cover 54. When the lower sliding plate 52 slides, it will drive the push rod 53 to move downward. Both ends of the lower sliding plate 52 are slidably connected to the inner wall of the chute. One end of the support telescopic rod 56 away from the blocking cover 54 is fixedly connected to the inner wall of the U-shaped frame 7.

[0053] A welding method for a sheet metal automatic positioning welding tool comprises the following steps:

[0054] S1: When the power device 12 moves, it drives the rotating shaft 13 to move in a direction close to each other. When the power device 12 moves, it squeezes the limit spring 14. When the limit spring 14 is squeezed, it shrinks in a direction close to each other. When the limit spring 14 shrinks to a certain position, it limits the power device 12 to prevent the power device 12 from contacting the support ring 20.

[0055] S2: When the positioning ring 18 expands, it will support the cylindrical sheet metal part and fix the sheet metal part to position it. When the sheet metal part is supported, the surface of the pulley 22 will contact the sheet metal part. When the ends of the two sheet metal parts are in contact, the motor 4 is turned off to keep it still, effectively positioning the sheet metal part, and supporting and fixing it through the surface of the positioning ring 18 and the inner wall of the sheet metal part, replacing the cumbersome steps and improving the welding efficiency.

[0056] S3: When the passive rod 51 moves, it pushes the lower slide plate 52 to slide downward on the inner wall of the slide groove. When the lower slide plate 52 slides, it drives the push rod 53 to move downward. When the push rod 53 moves, it pushes the blocking cover 54 to move in the direction of approaching each other. When the blocking cover 54 moves, it wraps the automatic welding machine 36, which can block the welding slag generated during the welding process, and can also isolate the arc generated during welding to prevent harm to the eyes of the staff;

[0057] S4: When the blocking cover 54 moves, it will pull the supporting telescopic rod 56 to extend in the direction of approaching each other. When the blocking cover 54 moves, it will drive the receiving plate 55 to move in the direction of approaching each other. At this time, the ends of the two receiving plates 55 will touch. At this time, the receiving plate 55 is located directly below the blocking cover 54. When the welding slag is blocked by the blocking cover 54, it will fall on the surface of the receiving plate 55, thereby achieving the effect of collecting the welding slag and saving the labor of the staff.

[0058] During use, first place the cylindrical sheet metal part to be welded on the surface of the positioning ring 18, and then start the motor 4 to drive the bidirectional threaded rod 5 to rotate. When the bidirectional threaded rod 5 rotates, the threaded rings 6 will move towards each other. When the threaded rings 6 move, they will drive the positioning platforms 11 to move towards each other. When the positioning platforms 11 move, they will drive the moving plates 3 to slide towards each other on the surface of the guide rails 2. When the positioning platforms 11 move, they will also drive the power devices 12 to move towards each other. When the power devices 12 move, they will drive the rotating shafts 13 to move towards each other. When the power devices 12 move, they will squeeze the limit springs 14. When the limit springs 14 are squeezed, they will contract towards each other. When the limit springs 14 contract in place, they will limit the power devices 12 to prevent the power devices 12 from contacting the support ring 20. When the rotating shafts 13 move, they will drive the grooves to move towards each other. At this time, due to the support of the pull rod 21, the sliding ring 16 remains stationary, while the fixed ring 19 will move with the rotating shaft 13 and push the push plate 17 to move away from each other. When the push plate 17 moves, it will push the positioning ring 18 to expand away from each other. When the positioning ring 18 expands, it will support the cylindrical sheet metal part and fix the sheet metal part for positioning. When the sheet metal part is supported, the surface of the pulley 22 will contact the sheet metal part. When the ends of the two sheet metal parts contact, turn off the motor 4 to keep it stationary. When the positioning platforms 11 move, they will push the right-angle frame 33 to move towards each other. When the right-angle frame 33 moves, it will push the sliding plate 32 to move towards each other on the inner wall of the chute plate 31. When the sliding plate 32 moves, it will push the lower push plate 34 to move downward. When the lower push plate 34 moves, it will push the driven plate 35 to move downward. When the driven plate 35 moves, it will drive the automatic welding machine 36 to move downward. When the automatic welding machine 36 moves to the joint of the two sheet metal parts and remains stationary, then start the automatic welding machine 36 to start welding. At the same time, start the power device 12 to drive the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it will drive the sliding ring 16 to rotate. When the sliding ring 16 rotates, it will drive the push plate 17 to rotate. When the sliding ring 16 rotates, it will drive the positioning ring 18 to rotate. When the positioning ring 18 rotates, it will drive the sheet metal part to rotate, so as to weld the sheet metal part and weld the two sheet metal parts together. When the driven plate 35 moves downward, it will drive the reinforcement ring 37 to move downward. When the runner 40 contacts the sheet metal part, it will squeeze the contact elastic frame 39 backward. When the contact elastic frame 39 is squeezed, it will push the extension ring 38 to extend away from each other in a circular shape on the inner wall of the extension groove. When the welding is completed, the motor 4 drives the bidirectional threaded rod 5 to reverse. When the bidirectional threaded rod 5 reverses, the two positioning platforms 11 will move away from each other. When the positioning platforms 11 move, they will drive the entire rotating shaft 13 to move. When the two positioning rings 18 move away from each other, they will gradually separate from the welded workpiece. When the positioning ring 18 separates from the sheet metal part, it will fall on the surface of the receiving table 8.When the driven plate 35 moves downward, it will drive the passive rod 51 to move downward. When the passive rod 51 moves, it will push the lower slide plate 52 to slide downward along the inner wall of the chute. When the lower slide plate 52 slides, it will drive the push rod 53 to move downward. When the push rod 53 moves, it will push the blocking cover 54 to move towards each other. When the blocking cover 54 moves, it will wrap the automatic welding machine 36, blocking the welding slag generated during the welding process and also isolating the arc light generated during welding to prevent harm to the eyes of the staff. When the blocking cover 54 moves, it will pull the support telescopic rod 56 to extend towards each other. When the blocking cover 54 moves, it will drive the material receiving plate 55 to move towards each other. At this time, the ends of the two material receiving plates 55 will contact. At this time, the material receiving plate 55 is located directly below the blocking cover 54. The welding slag blocked by the blocking cover 54 will fall on the surface of the material receiving plate 55.,
