Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and more particularly to an automatic welding equipment for tubular metal parts. Background Art

[0002] The metal railing consists of columns and cross bars. The columns are welded together by multiple pipe fittings and ball sleeves. The ball sleeves on multiple columns pass through the same cross bar to form a guardrail. The pipe fittings and ball sleeves are fixed by welding, and the opening direction of each ball sleeve needs to be consistent to ensure the smooth insertion of the cross bar. Therefore, it is necessary to set up a specific die, and the pipe fittings and ball sleeves are embedded in the die to achieve mutual contact between the pipe fittings and the ball sleeves, and then the contact surface is welded by welding equipment.

[0003] A Chinese patent with authorization publication number CN117464233A discloses a guardrail net assembly welding connection device. The pushing plate in the welding mechanism of the invention pushes the connecting piece to be welded to be close to the side of the metal frame, limits the left and right directions of the connecting piece while keeping the connecting piece close to the metal frame. Then, the lower pressure plate and the supporting block cooperate with each other to limit the up and down directions of the connecting piece. At the same time, the corresponding two adjustment plates limit the front and back directions of the connecting piece, finally keeping the connecting piece close to the metal frame. At the same time, the connecting piece is perpendicular to the side of the metal frame, avoiding the problem of low welding strength at the connection due to low fit between the connecting piece and the metal frame, and at the same time improving the welding accuracy, which facilitates the subsequent assembly operation of the welded guardrail net.

[0004] Although the dedicated welding positioning device of this type of guardrail net component has achieved welding precision control in theory, in industrial production practice, significant process adaptability defects are exposed when arc welding is performed on the spatial intersection structure of special-shaped metal pipes and ball nodes. Due to the asymmetric stress distribution characteristics of the multi-curved geometric configuration of the special-shaped pipes and ball nodes, micro-displacement caused by thermal deformation is easily generated during the welding thermal cycle. Even if a high-precision positioning system is used, radial offset will still occur. Summary of the Invention

[0029] A support rod 7 is provided on the front side of the reciprocating screw rod 1 6, and a reciprocating screw rod 2 5 is provided on the rear side of the reciprocating screw rod 1 6. The reciprocating screw rod 2 5 is rotatably connected to the workbench 1, and the support rod 7 is fixedly connected to the workbench 1. A gear 2 10 is fixedly installed on the outer surface of the reciprocating screw rod 1 6, and a gear 1 9 is provided on one side of the gear 2 10.

[0030] A motor 8 is fixedly mounted on the inner right end face of the workbench 1, and a gear 1 9 is fixedly mounted on the outer surface of the output shaft of the motor 8, which meshes with the gear 2 10. A gear 3 11 is fixedly mounted on the outer surface of the reciprocating screw 2 5, which meshes with the gear 1 9. One-way bearings are provided inside both the gear 2 10 and the gear 3 11.

[0031] The upper end surface of the workbench 1 is provided with a slide groove 17, and the interior of the slide groove 17 is slidably connected to a slider 18, and a transmission rod 2 19 is slidably connected to the slider 18. The outer surface of the reciprocating screw rod 2 5 is spirally connected to a threaded sleeve 21, and the outer surface of the support rod 7 is provided with a sliding sleeve 22. A pushing piece 20 is fixedly installed between the threaded sleeve 21 and the sliding sleeve 22, and the pushing piece 20 is slidably connected to the transmission rod 2 19.

[0032] This equipment cooperates with external multi-axis welding equipment to perform welding operations between pipe fittings 3 and spheres 4. First, pipe fittings 3 and spheres 4 are placed in corresponding positions, and then motor 8 is started to drive gear 1 9 to rotate forward. Gear 2 10 and gear 3 11 that are engaged with gear 1 9 are both provided with one-way bearings. At this time, reciprocating screw rod 2 5 does not rotate under the action of the one-way bearing inside gear 3 11, and reciprocating screw rod 1 6 rotates under the action of the one-way bearing inside gear 2 10. Therefore, the reciprocating screw The two groups of threaded sleeves 12 connected by spiral transmission at both ends of the outer surface of rod 16 will move away from each other. The thread groove on the outer surface of reciprocating screw rod 16 is a bidirectional thread groove, and the thread groove on the outer surface of reciprocating screw rod 2 5 is a unidirectional thread groove. Each group of threaded sleeves 12 will carry a group of connecting rods 13 for displacement, and the two groups of threaded sleeves 12 are rotatably connected to the top block 15 on the lower end surface of the cross bar 14, thereby driving the cross bar 14 to descend; the cross bar 14 descends and carries two groups of transmission rods 16 and one group of transmission rods 2 19 to descend.

[0033] The automated processing mechanism also includes a fixing part 1 arranged on the left side of the upper end surface of the workbench 1. The fixing part 1 includes two sets of support shafts 24 fixedly installed on the left and right end surfaces of the support platform 2. The outer surface of the support shaft 24 is rotatably connected to a clamping claw 25.

[0034] A transmission member 26 is provided between the two groups of support shafts 24. Two groups of slide grooves 3 27 are opened on the left end face of the transmission member 26. A slide rod 28 is fixedly installed on one end of the clamping jaw 1 25. The slide rod 28 is slidably connected to the slide groove 3 27. Two groups of clamping jaw 1 25 are symmetrically arranged.

[0035] The transmission rod 16 descends, carrying the transmission member 26 with it. The slide bar 28 on the clamp 25 is slidably connected to the slide groove 3 27 on the transmission member 26, so that the clamp 25 deflects around the support shaft 24 and deflects toward the pipe 3. The two sets of symmetrically arranged clamps 25 both deflect toward the pipe 3, thereby clamping and fixing the pipe 3. Two sets of symmetrical clamps 25 are provided at both ends of the pipe 3, thereby providing a stable fixing effect.

[0036] The automated processing mechanism also includes a fixing part 2 provided on the right side of the upper end surface of the workbench 1, and the fixing part 2 includes a transmission block 29 provided on the upper side of the workbench 1. The upper end of the transmission rod 219 extends to the upper side of the workbench 1 and is fixedly connected to the transmission block 29. A support ring 30 is provided on the outer side of the transmission block 29, and the support ring 30 is fixedly connected to the workbench 1.

[0037] The outer surface of the support ring 30 is rotatably connected to the clamping jaw 2 31, and the end of the clamping jaw 2 31 is provided with a sliding groove 4 33. The inside of the sliding groove 4 33 is slidably connected to the fixed shaft 32, and the fixed shaft 32 is fixedly connected to the transmission block 29. The clamping jaw 2 31 is provided in three groups and is dispersedly arranged in a ring shape.

[0038] When the transmission rod 219 descends, the transmission block 29 will be carried down with it, and the fixed shaft 32 on the transmission block 29 will descend synchronously. The fixed shaft 32 is slidably connected with the slide groove 4 33 on the clamp 21, thereby driving the clamp 21 to deflect toward the sphere 4 around the support ring 30. The three groups of annularly dispersed clamps 31 deflect toward the sphere 4 synchronously, thereby fixing the sphere 4.

[0039] The automated processing mechanism also includes an auxiliary part arranged on the front side of the adjusting part. The auxiliary part includes a fixing plate 34 fixedly installed on the front end surface of the cross bar 14, an air bag 35 fixedly installed between the fixing plate 34 and the workbench 1, and a connecting pipe 36 is provided at the upper end of the air bag 35.

[0040] Suction ports 37 are formed on the inner sides of the first clamping jaw 25 and the second clamping jaw 31 , and the plurality of suction ports 37 are connected to the connecting pipe 36 .

[0041] When the cross bar 14 descends, it will pull the airbag 35 through the fixed plate 34, and the airbag 35 will pass through the connecting tube 36 to allow the suction ports 37 opened on the inner wall of each group of jaws 1 25 and jaw 2 31 to suck gas. Each group of suction ports 37 is in close contact with its respective workpiece, thus creating a vacuum suction effect, further improving the stability of the pipe 3 and the sphere 4.

[0042] After the fixation is completed, the output shaft of the motor 8 can drive the gear 19 to reverse. At this time, the reciprocating screw 16 will not rotate, and the reciprocating screw 25 will rotate. The threaded sleeve 21 connected to the spiral transmission on the outer surface of the reciprocating screw 25 will drive the slider 18 to move through the pushing member 20. The sphere 4 in the fixed state on the slider 18 is synchronously displaced and approaches the pipe 3, and is tightly attached to the pipe 3. Then, the external welding equipment is started to weld the pipe 3 and the sphere 4. When the welding is completed, the output shaft of the motor 8 can be continued to be driven to make the gear 19 continue to rotate forward and the reciprocating screw 6 continue to rotate. Due to the characteristics of the reciprocating screw 6, the two sets of threaded sleeves 12 will move in the opposite direction when they move to the end, so that the cross bar 14 can be raised, thereby releasing the fixation of the pipe 3 and the sphere 4.

[0043] In industrial production practice, when arc welding is performed on the spatial intersection structure of the special-shaped metal pipe 3 and the ball node, significant process adaptability defects are exposed. Due to the asymmetric stress distribution characteristics of the multi-curved geometric configuration of the special-shaped pipe 3 and the ball node, micro-displacement caused by thermal deformation is easily generated during the welding thermal cycle. Even if a high-precision positioning system is used, radial offset will still occur. Therefore, this solution sets up an automated processing mechanism and cooperates with an external welding device to perform welding operations between the pipe 3 and the sphere 4, and provide a stable fixing effect to avoid shaking during welding. At the same time, the auxiliary parts further enhance the fixing effect of the workpiece.

[0044] Instructions for use: This equipment cooperates with external multi-axis welding equipment to perform welding operations between pipe fittings 3 and spheres 4. First, pipe fittings 3 and spheres 4 are placed in corresponding positions, and then motor 8 is started to drive gear 1 9 to rotate forward. Gear 2 10 and gear 3 11 that are engaged with gear 1 9 are both provided with one-way bearings. At this time, reciprocating screw 2 5 does not rotate under the action of the one-way bearing inside gear 3 11, while reciprocating screw 1 6 rotates under the action of the one-way bearing inside gear 2 10. Therefore, The two sets of threaded sleeves 12 connected by spiral transmission at both ends of the outer surface of the reciprocating screw rod 16 will move away from each other. The thread groove on the outer surface of the reciprocating screw rod 16 is a bidirectional thread groove, and the thread groove on the outer surface of the reciprocating screw rod 25 is a unidirectional thread groove. Each set of threaded sleeves 12 will carry a set of connecting rods 13 for displacement, and the two sets of threaded sleeves 12 are rotatably connected to the top block 15 on the lower end surface of the cross bar 14, thereby driving the cross bar 14 to descend; the cross bar 14 descends and carries the two sets of transmission rods 16 and the one set of transmission rods 2 19 to descend;

[0045] The transmission rod 16 descends, bringing the transmission member 26 downward. The slide bar 28 on the clamping jaw 25 is slidably connected to the slide groove 3 27 on the transmission member 26, thereby causing the clamping jaw 25 to deflect around the support shaft 24 and deflect toward the pipe 3. The two sets of symmetrically arranged clamping jaws 25 both deflect toward the pipe 3, thereby clamping and fixing the pipe 3. Two sets of symmetrical clamping jaws 25 are provided at both ends of the pipe 3, thereby providing a stable fixing effect.

[0046] When the transmission rod 19 descends, the transmission block 29 is brought down with it, and the fixed shaft 32 on the transmission block 29 descends synchronously. The fixed shaft 32 is slidably connected with the fourth slide groove 33 on the second clamping jaw 31, thereby driving the second clamping jaw 31 to deflect toward the ball 4 around the support ring 30. The three groups of annularly dispersed clamping jaws 31 deflect synchronously toward the ball 4, thereby fixing the ball 4;

[0047] When the crossbar 14 descends, it pulls the airbag 35 through the fixed plate 34. The airbag 35 then draws gas through the connecting tube 36, causing the suction ports 37 on the inner wall of each set of jaws 1 25 and jaw 2 31 to draw gas. Each set of suction ports 37 is in close contact with its respective workpiece, thus creating a vacuum suction effect, further enhancing the stability of the tube 3 and the sphere 4.

[0048] After the fixation is completed, the output shaft of the motor 8 can drive the gear 9 to reverse. At this time, the reciprocating screw 6 will not rotate, and the reciprocating screw 2 5 will rotate. The threaded sleeve 21 connected to the spiral transmission on the outer surface of the reciprocating screw 2 5 will drive the slider 18 to move through the pushing member 20. The sphere 4 in the fixed state on the slider 18 is synchronously displaced and approaches the pipe 3, and is tightly attached to the pipe 3. Then, the external welding equipment is started to weld the pipe 3 and the sphere 4. When the welding is completed, the output shaft of the motor 8 can be continued to be driven to make the gear 9 continue to rotate forward and the reciprocating screw 6 continue to rotate. Due to the characteristics of the reciprocating screw 6, the two sets of threaded sleeves 12 will move in the opposite direction when they move to the end, so that the cross bar 14 can be raised, thereby releasing the fixation of the pipe 3 and the sphere 4.

[0049] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
