Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of welding technology, and more specifically, to an automatic welding machine for the production of seismic brackets. Background Art

[0002] A seismic bracket is various components or devices that restrict the displacement of auxiliary mechanical and electrical engineering facilities, control the vibration of the facilities, and transfer the load to the bearing structure. During the production and processing of seismic brackets, a welding machine is required to weld the bracket base.

[0003] In the prior art, a welding machine performs T-shaped welding on the clamped section steel and steel plate to form a welding base for the installation of seismic brackets. The welding quality has a great influence on the performance of seismic brackets. Especially for the welding base, the vertical relationship between the section steel and the steel plate has a great influence on the accuracy of the assembly and the seismic performance of the seismic bracket. During the welding process, it is necessary to ensure the vertical relationship between the welding components. Currently, the welding machine uses fixtures to clamp and limit the welding components. Generally, only the section steel is pressed tightly on the top of the steel plate. However, due to the burrs at the end of the steel components, especially at the welding position, the angle between the welding components may deviate to a certain extent during clamping. At the same time, the automatic welding machine uses one welding head to weld the two sides of the section steel in sequence. After one side is welded, the steel component will deform to a certain extent due to the heat generated by welding. When welding the other side, there will also be a certain angle deviation, making it difficult to ensure the perpendicularity between the section steel and the steel plate, which has a certain impact on subsequent installation. Summary of the Invention

[0004] To overcome the above defects, embodiments of the present disclosure provide an automatic welding machine for the production of seismic brackets, which solves the technical problem in the prior art that it is difficult to ensure the perpendicularity of the welding components due to burrs and welding heat during the welding process, reducing the installation accuracy.

[0025] Such as Figures 1 to 11As shown in the figure, it shows an automatic welding machine for the production of seismic brackets in an embodiment of the present disclosure, including a frame body 1 and welding heads 2. There are two welding heads 2, and it also includes a moving mechanism, a clamping mechanism, a clamping plate 3 and a grinding mechanism. Compared with the automatic welding machine for the production of seismic brackets in the prior art, in the present disclosure, the position of the welding head 2 is adjusted by the movement of the moving frame 101 and the welding arm 102 and the lifting of the welding head 2 to adapt to the welding of profiled steel and steel plates. By setting two welding heads 2, the two sides of the welding position can be welded simultaneously, reducing the thermal deformation caused by welding one side first, thereby ensuring the perpendicularity of the profiled steel and the steel plate after welding. At the same time, the bottom end of the profiled steel and the top end of the steel plate are ground by the grinding disc 402 and the grinding belt 502 to grind the welding position of the profiled steel and the steel plate flat. Then, the welding position is purged by the air blowing pipe 701 to facilitate the butt joint and welding between the profiled steel and the steel plate, further ensuring the perpendicularity between the two and improving the installation accuracy of the subsequent seismic brackets.

[0026] The moving mechanism is used to drive the welding head 2 to move for welding workpieces. The moving mechanism includes a moving frame 101 and a welding arm 102. The moving frame 101 is movably arranged on the frame body 1. A lead screw feeding mechanism 103 is installed on the frame body 1. The moving frame 101 and the frame body 1 are in sliding fit, and the moving frame 101 is fixedly installed on the nut seat in the lead screw feeding mechanism 103. The lead screw feeding mechanism 103 can drive the moving seat 301 to move along the transverse direction of the frame body 1. There are two welding arms 102. The welding arms 102 are movably arranged on the moving frame 101. The welding arms 102 and the moving frame 101 are in sliding fit. Two first motors 104 are installed on the moving frame 101. The output end of the first motor 104 is fixedly connected with a driving gear 105. A driven rack 106 is fixedly connected to the welding arm 102. The driven racks 106 and the driving gears 105 are in one-to-one correspondence. The driven rack 106 and the driving gear 105 are meshed. The first motor 104 can drive the driving gear 105 to rotate, driving the driven rack 106 and the welding arm 102 to move along the longitudinal direction of the frame body 1. The moving direction of the welding arm 102 and the moving direction of the moving frame 101 are perpendicular to each other. The welding heads 2 and the welding arms 102 are in one-to-one correspondence. The welding heads 2 are vertically movable on the welding arms 102. An electric cylinder 107 is installed on the welding arm 102. The welding head 2 is fixedly connected to the output end of the electric cylinder 107 through a welding frame. The welding head 2 is equipped with an air pipe for conveying protective gas, as well as a welding power source and a controller. The welding of the welding head 2 is the prior art well-known to those skilled in the art and is not the innovation point of this disclosure, so it will not be elaborated here. Through the movement of the moving seat 301 and the welding arm 102 and the lifting of the electric cylinder, the welding head 2 can move relatively freely to weld different positions of the workpiece. There are two welding heads 2, which can make the two welding heads 2 located on both sides of the welding position. The two welding heads 2 weld synchronously, avoiding thermal deformation of the section steel and steel plate caused by one side welding first, thus ensuring the welding accuracy of the section steel and steel plate and reducing the offset and inclination of the section steel. It should be noted that two sliding seats 108 are slidably connected to the top of the moving frame 101. The welding arms 102 and the sliding seats 108 are in one-to-one correspondence. The welding arms 102 and the sliding seats are in sliding fit. A double-headed cylinder 109 is installed on the moving frame 101, which can adjust the distance between the two sliding seats, that is, adjust the distance between the two welding heads 2 to adapt the distance between the two welding heads 2 to the width of the section steel. When the welding head 2 descends, it is exactly located on both sides of the bottom end of the section steel, that is, the welding position. The two first motors 104 are respectively installed on the corresponding sliding seats 108.

[0027] The clamping mechanism is used to clamp and position the profiled steel. The clamping mechanism includes a lifting plate 201, a first clamping plate 202 and a second clamping plate 203. The lifting plate 201 is arranged on the frame 1 in a liftable manner. An electric cylinder two 204 is installed on the frame 1. The lifting plate 201 is fixedly connected to the output end of the electric cylinder two 204. There are two first clamping plates 202 and two second clamping plates 203. The first clamping plates 202 and the second clamping plates 203 are both movably arranged on the lifting plate 201. A motor two 205 is installed on the lifting plate 201. The output end of the motor two 205 is fixedly connected with a bidirectional screw 206. The two first clamping plates 202 are symmetrically arranged outside the bidirectional screw 206. Two sections of threads with opposite helix directions are arranged on the bidirectional screw 206. The two first clamping plates 202 are respectively provided with internal thread holes matching the two thread sections. A sliding opening for the first clamping plate 202 to pass through is opened on the lifting plate 201. Two electric cylinders three 207 are installed on the lifting plate 201. The second clamping plates 203 correspond to the electric cylinders three 207 one by one. The second clamping plates 203 are fixedly connected to the output ends of the electric cylinders three 207. The two electric cylinders three 207 move relatively, the two first clamping plates 202 move relatively, and the two second clamping plates 203 move relatively. The moving directions of the first clamping plate 202 and the second clamping plate 203 are perpendicular to each other. By driving the bidirectional screw 206 to rotate through the motor two 205, the two first clamping plates 202 can be close to or away from each other. By driving the two second clamping plates 203 to be close to or away from each other through the two electric cylinders three 207, a clamping groove matching the second clamping plate 203 is opened on the first clamping plate 202. The four sides of the profiled steel can be stably clamped by the two first clamping plates 202 and the two second clamping plates 203. The first clamping plate 202 and the second clamping plate 203 have a certain height. The first clamping plate 202 and the second clamping plate 203 are in close contact with the profiled steel, so that the profiled steel can be kept in a vertical state and perpendicular to the steel plate. By driving the lifting plate 201 to lift through the electric cylinder two 204, the profiled steel can be driven to lift, so that the profiled steel rises for grinding or descends and is in close contact with the steel plate for welding.

[0028] There are four clamping plates 3. The clamping plates 3 are movably arranged on the frame 1. The clamping plates 3 are in contact with the edges of the steel plate. The top height of the clamping plates 3 is lower than the top height of the steel plate. Four electric cylinders four 4 are installed on the frame 1. The clamping plates 3 correspond to the electric cylinders four 4 one by one. The clamping plates 3 are fixedly connected to the output ends of the electric cylinders four 4. The steel plate is placed between the four clamping plates 3. By driving the clamping plates 3 to approach the steel plate through the electric cylinders four 4, the steel plate can be positioned. The positions of the clamping plates 3 correspond to the positions of the first clamping plates 202 and the second clamping plates 203, so that the positions of the profiled steel and the steel plate correspond, ensuring the accuracy of welding. The clamping plates 3 are lower than the steel plate, avoiding obstacles to the grinding and welding of the steel plate.

A tensioning wheel 608 is rotatably connected to the tensioning block 610. The tensioning wheel 608 is in external contact with the chain. The tensioning wheel 608 is located below the chain. The tensioning spring presses the tensioning wheel 608 against the surface of the chain to ensure the tension of the chain, thereby ensuring the stable transmission between the grinding roller 501 and the transmission shaft 606. The motor three 609 drives the drive shaft 601 and the driving gear 602 to rotate. Under the action of the transmission gear 604, the driven toothed ring 603 and the main board 401 are driven to rotate. The main board 401 drives the grinding disc 402 to rotate through the telescopic rod. The two grinding discs 402 are pressed against the surfaces of the steel plate and the section steel under the action of the compression spring. The bottom end of the section steel and the top end of the steel plate are ground by the grinding disc 402 to grind the welding surface flat and make the two end faces parallel, thereby ensuring the perpendicularity of the section steel and the steel plate. The welding arm 102 drives the moving seat 301 to move, so that the grinding disc 402 moves to grind the surfaces of the section steel and the steel plate more comprehensively. Then the grinding belt 502 is moved between the section steel and the steel plate. The drive shaft 601 drives the drive bevel gear 605 to rotate, thereby driving the driven bevel gear 607 and the transmission shaft 606 to rotate. The grinding roller 501 is driven to rotate under the transmission of the sprocket and chain, thereby driving the grinding belt 502 to make a rotary motion. Two pressing blocks 5 are slidably arranged on the moving seat 301. A pressing roller 7 is rotatably connected to the pressing block 5. A contraction spring 6 is connected between the two pressing blocks 5.

The two grinding rollers 501 at the top and the two grinding rollers 501 at the bottom make the top end and the bottom end of the grinding belt 502 in a horizontal state. And under the action of the support spring 504, the top end of the grinding belt 502 is pressed against the bottom end of the section steel, and the bottom end of the grinding belt 502 is pressed against the top end of the steel plate, thereby finely grinding the section steel and the steel plate. Under the action of the contraction spring 6, the two pressing rollers 7 approach each other to tension the grinding belt 502, thereby ensuring the stable rotary motion of the grinding belt 502. At the same time, under the action of the tensioning wheel 608, an upward force is given to the chain. The sprocket is fixedly sleeved on one of the upper grinding rollers 501, which can assist the top end of the grinding belt 502 to be pressed against the surface of the section steel.,

[0030] To reduce the impact of grinding debris on welding, it further includes a purging assembly. The purging assembly is used to purge the grinding position. The purging assembly includes a blowing air pipe 701 and a blower 702. The blowing air pipe 701 is fixedly connected to the welding head 2, and the air outlet of the blowing air pipe 701 faces the welding position of the welding head 2. The air outlet of the blower 702 is communicated with the blowing air pipe 701. By moving the moving frame 101, the welding arm 102, and lifting the electric cylinder 107 to drive the movement of the welding head 2, the blowing air pipe 701 rises and falls with the welding head 2, and its air outlet faces the welding head 2. The blower 702 sends air into the blowing air pipe 701, and the welding position can be purged before welding to avoid the impact of the debris generated by grinding on welding.

[0031] To reduce the thermal deformation of the profiled steel and the steel plate after welding, it further includes a cooling assembly. The cooling assembly is used to cooperate with the purging assembly to cool the welding position. The cooling assembly includes a cold water tank 801 and a cold air pipe 802. The cold water tank 801 is fixedly connected to the welding arm 102, and the cold air pipe 802 is located inside the cold water tank 801. The air outlet of the blower 702 is communicated with the blowing air pipe 701 through the cold air pipe 802. The cold water tank 801 can be communicated with a refrigeration device or a faucet to ensure that cold water is always stored inside the cold water tank 801. The blower 702 transports air into the cold air pipe 802, and the air in the cold air pipe 802 is cooled by the cold water. The cold air pipe 802 is arranged in a bent shape inside the cold water tank 801, so that the air inside it can fully contact and exchange heat with the cold water, ensuring that the air blown out by the blowing air pipe 701 is in a low-temperature state. The blowing air pipe 701 is communicated with the cold air pipe 802 through a telescopic hose. The telescopic of the telescopic hose can adapt to the lifting of the electric cylinder 107 to drive the welding head 2 and the blowing air pipe 701. After welding, cold air is blown through the blower 702 and the blowing air pipe 701 to cool the welding position, reduce the deformation generated after the profiled steel and the steel plate are welded, and at the same time facilitate the collection of the welded seismic support base.

[0032] The working principle or usage process of the automatic welding machine for producing seismic supports is as follows: Place the steel plate between the four clamping plates 3. The electric cylinder 4 drives the clamping plates 3 to clamp the steel plate. Place the profiled steel on the steel plate and between the clamping plate 1 202 and the clamping plate 2 203. The motor 2 drives the bidirectional screw 206 to rotate, so that the two clamping plates 1 202 clamp the profiled steel. At the same time, the electric cylinder 3 207 drives the clamping plate 2 203 to clamp the other two sides of the profiled steel, so that the positions of the profiled steel and the steel plate correspond. The electric cylinder 2 204 drives the lifting plate 201 and the profiled steel to press down on the steel plate, so that the steel plate is tightly attached to the top of the frame 1 to ensure the horizontal state of the steel plate. Then the electric cylinder 2 204 drives the lifting plate 201 to rise, so that the profiled steel is away from the steel plate; The first motor 104 drives the driving gear 105 to rotate, causing the welding arm 102 to move. The lead screw feeding mechanism 103 drives the moving frame 101 to move, adjusting the position of the moving seat 301 to make the grinding disc 402 and the grinding belt 502 correspond to the positions of the profiled steel and the steel plate. As the lead screw feeding mechanism 103 drives the moving frame 101 to move, the grinding disc 402 first moves between the profiled steel and the steel plate. The two grinding discs 402 respectively contact the bottom end of the profiled steel and the top end of the steel plate. The motor drives the main board 401 to rotate, thereby driving the two grinding discs 402 to rotate, and roughly grinding the welding position of the profiled steel and the steel plate. Then the moving frame 101 drives the moving seat 301 to continue moving, making the grinding belt 502 move between the profiled steel and the steel plate. The grinding roller 501 drives the grinding belt 502 to perform a rotary motion, finely grinding the welding position of the profiled steel and the steel plate. While grinding the profiled steel and the steel plate flat, the horizontal state of their welding surfaces is ensured; Then the second electric cylinder 204 drives the lifting plate 201 and the profiled steel to descend, making the top ends of the profiled steel and the steel plate close tightly. The moving frame 101 and the welding arm 102 move, making the two welding heads 2 move to both sides of the profiled steel. The blower 702 sends air into the air blowing pipe 701 to purge the welding position. The first electric cylinder 107 drives the welding head 2 to descend to its welding position, and then the welding arm 102 makes the welding head 2 move longitudinally to synchronously weld both sides of the profiled steel and the steel plate. After one side is welded, the moving frame 101 drives the welding head 2 to move horizontally to weld the remaining side of the profiled steel and the steel plate; After welding is completed, the first electric cylinder 107 drives the welding head 2 to rise, and the air blowing pipe 701 continues to blow air at the welding position. The cold water in the cold water tank 801 cools the air in the cold air pipe 802, thereby cooling the welding position. Then the anti-seismic support base after welding is collected.
