Description

Technical Field

[0001] The invention relates to the technical field of welding processing, in particular to automatic welding processing equipment for thin-walled metal hoses. Background Art

[0002] Metal hose is an important component of the connecting pipeline of modern industrial equipment. Metal hose products include oil delivery and suction hose, steam hose, sandblasting hose, acid and alkali delivery and suction hose, food hose, oxygen blowing hose and various special-shaped hoses. It is widely used in machinery, chemical, petroleum, metallurgy, food and other industries. Metal hose is generally composed of three parts: bellows, mesh and joint. The bellows is the main body of the metal hose and plays a flexible role; the mesh plays a role of strengthening and shielding; the joint plays a connecting role. For different usage requirements, the ways of connecting them to each other are different: the three parts of the bellows, mesh and joint are connected in the form of welding, which is called welding type; the connection in the form of mechanical clamping is called mechanical clamping type. In addition, there is a combination of the above two methods, which is called mixed type.

[0003] At present, when welding a metal hose, it is necessary to weld the metal hose and the joint. Since the metal hose is highly flexible, it is easy to deform when docking with the joint. It cannot fit with the joint during welding, resulting in deviations in the welding point. Summary of the invention

The staff adjusts the position of the positioning assembly and the slide seat in the guide rail according to the position of the welding assembly, and clamps and fixes the metal hose and the joint respectively through the positioning assembly and the clamping inner support assembly. The clamping inner support assembly clamps the joint and supports the inside of the metal hose at the same time, so as to stably support the welding position of the metal hose and prevent the joint from being set on the outside of the metal hose and the hose in the joint from being easily deformed and unable to fit with the inner wall of the joint when the welding assembly is used to weld the two, resulting in deviation of the welding point.

[0008] Preferably, the clamping inner support assembly includes a support seat, a mounting shaft is fixedly installed inside the support seat, the mounting shaft is fixedly installed on the top of the first lifting seat, an extension rod is rotatably installed at the center of the outer surface of the mounting shaft, a support is fixedly installed at the end of the extension rod, a side connection block is fixedly installed on the outer surface of the extension rod, four side connection blocks are provided, and a clamp is fixedly installed on the outer surface of each of the four side connection blocks, the clamp is clamped on the outer surface of the joint, and the support passes through the joint and extends to the inside of the metal hose. When welding the metal hose and the joint, the staff sets the joint on the outside of the support and moves the joint into the clamp so that the clamp clamps the joint. After the joint is clamped and fixed, the staff adjusts the position of the slide so that the slide drives the clamping inner support assembly to move to the position of the positioning assembly. At this time, the support is located on the outside of the positioning assembly, and then the staff passes the metal hose through the positioning assembly and sets it on the surface of the support. The support supports the inside of the metal hose while the metal hose is docked with the joint to facilitate subsequent welding work.

[0009] Preferably, the support member includes an extension tube, a center block is fixedly installed inside the extension tube, a through plate is fixedly installed on the outer surface of the center block, four through plates are provided, and the four through plates are symmetrically arranged with the extension tube as the center, the through plate penetrates the extension tube and extends to the outside thereof, a round rod is fixedly installed in the middle of the outer surface of the through plate, a mounting block is fixedly installed inside the round rod, both sides of the outer surface of the mounting block are rotatably installed with rotating rods, the outer surface of the rotating rod is fixedly installed with connecting rods, and the outer surface of the connecting rod is fixedly installed with inner arc pads. When the staff sets the metal hose on the surface of the inner arc pad, the inner arc pad adjusts the position of the rotating rod according to the inner diameter of the metal hose, so that the rotating rod drives the connecting rod to rotate on both sides of the mounting block. Since the connecting rods are installed at both ends of the inner arc pad, the inner arc pad is stretched when the two connecting rods rotate, so that multiple groups of inner arc pads can support the metal hose according to the inner diameter of the metal hose, so as to support and shape the metal hose, and avoid deformation of the thin-walled metal hose during welding, which affects the welding effect.

After the staff sets the joint on the outer side of the extension rod, the joint moves the joint to the bottom of the bending frame. At this time, the joint squeezes the clamping piece, so that the clamping piece and the squeezing pad are deformed by force and are clamped on the outer side of the joint, so as to flexibly clamp the joint from multiple angles to avoid deformation of the joint and the metal hose caused by excessive clamping force.

[0014] Preferably, the mounting frame is fixedly mounted on the top of the second lifting seat, and the welding head is movably mounted on the outside of the clamping inner support assembly and the positioning assembly through a connecting block.

Then the staff adjusts the position of the guide slider according to the shape of the metal hose, so that the guide slider drives the inner connecting plate and the clamp block to slide on the surface of the guide rod, and clamps the metal hose through the clamp block. When the welding head welds the metal hose and the joint, the staff starts the rotating plate so that the rotating plate drives the metal hose clamped in the clamp block to rotate. Since the inside of the metal hose fits the support member, the support member and the extension rod are rotated when the metal hose rotates, thereby driving the joint clamped by the clamp member on the outside of the extension rod to rotate, so that the welding head can fully weld the connection between the metal hose and the joint.

[0016] Preferably, the support frame is slidably installed inside the guide rail, and two groups of guide rods are provided. The two groups of guide rods are symmetrically arranged with the rotating plate as the center, and the clamping block is clamped on the outer surface of the metal hose.

[0017] The present invention provides a thin-walled metal hose automatic welding processing equipment. It has the following beneficial effects:

[0018] 1. The thin-walled metal hose automatic welding processing equipment needs to weld the metal hose and the joint when the staff welds the metal hose. The staff adjusts the position of the positioning component and the slide seat in the guide rail according to the position of the welding component, and clamps and fixes the metal hose and the joint respectively through the positioning component and the clamping inner support component. The clamping inner support component clamps the joint and supports the inside of the metal hose at the same time to stably support the welding position of the metal hose, preventing the joint from being set on the outside of the metal hose and welding the two through the welding component. The hose in the joint is prone to deformation and cannot fit with the inner wall of the joint, resulting in deviation in the welding point.

[0019] 2. The thin-walled metal hose automatic welding processing equipment, when welding the metal hose and the joint, the staff puts the joint on the outside of the support and moves the joint into the clamping part, so that the clamping part clamps the joint. After the joint is clamped and fixed, the staff adjusts the position of the slide seat, so that the slide seat drives the clamping inner support component to move to the position of the positioning component. At this time, the support member is located on the outside of the positioning component, and then the staff passes the metal hose through the positioning component and puts it on the surface of the support member. The support member supports the inside of the metal hose while the metal hose is connected to the joint to facilitate subsequent welding work.

[0020] 3. The automatic welding processing equipment for thin-walled metal hose, when the staff puts the metal hose on the surface of the inner arc pad, the inner arc pad adjusts the position of the rotating rod according to the inner diameter of the metal hose, so that the rotating rod drives the connecting rod to rotate on both sides of the mounting block. Since the connecting rods are installed at both ends of the inner arc pad, the inner arc pad is stretched when the two connecting rods rotate, so that multiple groups of inner arc pads can support the metal hose according to the inner diameter of the metal hose, so as to support and shape the metal hose, thereby avoiding deformation of the thin-walled metal hose during welding and affecting the welding effect.

[0021] 4. The thin-walled metal hose automatic welding processing equipment is used by the staff to put the joint on the outside of the extension rod and then move the joint to the bottom of the bending frame. At this time, the joint squeezes the clamping plate, so that the clamping plate and the extrusion pad are deformed under the force and clamped on the outside of the joint, so as to flexibly clamp the joint from multiple angles to avoid deformation of the joint and the metal hose caused by excessive clamping force.

[0022] 5. The thin-walled metal hose automatic welding processing equipment, when clamping and fixing the metal hose, the staff moves the clamping inner support assembly to the outside of the clamping block, the staff puts the metal hose on the top of the bottom support frame, and passes it through the rotating plate, so that the metal hose is sleeved on the surface of the support member, so that the inside of the metal hose is supported and shaped by the support member, and then the staff adjusts the position of the guide slider according to the shape of the metal hose, so that the guide slider drives the inner connecting plate and the clamping block to slide on the surface of the guide rod, and clamps the metal hose through the clamping block. When the welding head welds the metal hose and the joint, the staff starts the rotating plate, so that the rotating plate drives the metal hose clamped in the clamping block to rotate. Since the inside of the metal hose fits the support member, the support member and the extension rod are rotated when the metal hose rotates, thereby driving the joint clamped by the clamping member on the outside of the extension rod to rotate, so that the welding head can fully weld the connection between the metal hose and the joint.

After the joint is clamped and fixed, the staff will adjust the position of the slide 5, so that the slide 5 drives the clamping inner support component 4 to move toward the position of the positioning component 2. At this time, the support member 45 is located on the outside of the positioning component 2, and then the staff will pass the metal hose through the positioning component 2 and put it on the surface of the support member 45. The support member 45 supports the inside of the metal hose while the metal hose is connected to the joint to facilitate subsequent welding work.

[0040] A positioning assembly 2, which is used for guiding and clamping the metal hose. The positioning assembly 2 is slidably mounted inside the guide rail 6. The positioning assembly 2 and the clamping inner support assembly 4 are arranged on the same central axis;

[0041] The positioning assembly 2 includes a support frame 28, a frame plate 21 is fixedly installed on the outer surface of the support frame 28, a bottom support frame 27 is fixedly installed on the surface of the frame plate 21 close to the support frame 28, a rotating plate 24 is rotatably installed on the surface of the frame plate 21 away from the bottom support frame 27, guide rods 26 are fixedly installed on both sides of the outer surface of the rotating plate 24, a guide slider 25 is slidably installed on the outer surface of the guide rod 26, an inner plate 22 is fixedly installed inside the guide slider 25, and a clamping block 23 is fixedly installed on the surface of the inner plate 22. When clamping and fixing the metal hose, the staff moves the clamping inner support assembly 4 to the outside of the clamp block 23, and the staff places the metal hose on top of the bottom support frame 27 and passes it through the rotating plate 24, so that the metal hose is sleeved on the surface of the support member 45, so that the inside of the metal hose is supported and shaped by the support member 45, and then the staff adjusts the position of the guide slider 25 according to the shape of the metal hose, so that the guide slider 25 drives the inner connecting plate 22 and the clamp block 23 to slide on the surface of the guide rod 26, and clamps the metal hose through the clamp block 23. When the welding head 37 welds the metal hose and the joint, the staff starts the rotating plate 24, so that the rotating plate 24 drives the metal hose clamped in the clamp block 23 to rotate. Since the inside of the metal hose fits against the support member 45, when the metal hose rotates, it drives the support member 45 and the extension rod 44 to rotate, thereby driving the joint clamped by the clamp member 46 on the outside of the extension rod 44 to rotate, so that the welding head 37 can fully weld the connection between the metal hose and the joint.

[0042] The support frame 28 is slidably mounted inside the guide rail 6 , and two groups of guide rods 26 are provided. The two groups of guide rods 26 are symmetrically arranged with the rotating plate 24 as the center, and the clamping block 23 is clamped on the outer surface of the metal hose.

[0043] The welding assembly 3 has a second lifting seat 9 fixedly mounted on the bottom of the welding assembly 3 , and the second lifting seat 9 is movably mounted on the top of the fixed seat 8 . The welding assembly 3 is arranged on one side of the top of the base 1 through the fixed seat 8 .

[0044] The welding assembly 3 includes a mounting frame 38, a driving member 31 is fixedly installed inside the mounting frame 38, a positioning frame 32 is fixedly installed on the outer surface of the driving member 31, a connecting block 34 is rotatably installed inside the positioning frame 32, a limiting frame 35 is fixedly installed on the outer surface of the connecting block 34, a connecting plate 36 is fixedly installed between adjacent surfaces of the limiting frame 35, a connecting pipe 33 is fixedly installed on the top of the connecting plate 36, and a welding head 37 is fixedly installed on the bottom of the connecting pipe 33. After the metal hose and the joint are docked and fixed, the staff starts the driving member 31, so that the driving member 31 drives the connecting block 34 to rotate to drive the limiting frame 35 to rotate, so as to adjust the inclination angle of the welding head 37, so that the welding head 37 welds the connection between the metal hose and the joint.

[0045] The mounting frame 38 is fixedly mounted on the top of the second lifting seat 9, and the welding head 37 is movably mounted on the outside of the clamping inner support component 4 and the positioning component 2 through the connecting block 34. When welding the metal hose, the staff needs to weld the metal hose and the joint. The staff adjusts the position of the positioning component 2 and the slide 5 in the guide rail 6 according to the position of the welding component 3, and clamps and fixes the metal hose and the joint respectively through the positioning component 2 and the clamping inner support component 4. The clamping inner support component 4 clamps the joint and supports the inside of the metal hose at the same time, so as to stably support the welding position of the metal hose and prevent the joint from being easily deformed when the joint is set on the outside of the metal hose and the two are welded by the welding component 3, and the hose in the joint cannot fit with the inner wall of the joint, resulting in deviation of the welding point.

[0046] The second embodiment is based on the first embodiment. Figures 8 to 10 As shown, the clamping member 46 includes a connecting plate 461, a fixing plate 462 is fixedly installed on the outer surface of the connecting plate 461, a supporting block 464 is fixedly installed inside the fixing plate 462, and three supporting blocks 464 are provided, and a bent frame 463 is fixedly installed at the bottom of the three supporting blocks 464, and clamping pieces 465 are fixedly installed on both sides of the outer surface of the bent frame 463. After the staff sets the joint on the outer side of the extension rod 44, the joint moves the joint to the bottom of the bent frame 463. At this time, the joint squeezes the clamping piece 465, so that the clamping piece 465 and the squeezing pad 466 are deformed by force and clamped on the outer side of the joint, so as to flexibly clamp the joint from multiple angles to avoid deformation of the joint and the metal hose caused by excessive clamping force.

[0047] The connecting plate 461 is fixedly mounted on one side of the outer surface of the side connecting block 43 , the clamping piece 465 is made of a flexible material, and a compression pad 466 is disposed on the surface of the clamping piece 465 , and the compression pad 466 is clamped on the outer surface of the joint.

[0048] The third embodiment is based on the first and second embodiments. Figure 11 to Figure 12As shown, the support member 45 includes an extension tube 451, a center block 453 is fixedly installed inside the extension tube 451, a through plate 452 is fixedly installed on the outer surface of the center block 453, four through plates 452 are provided, and the four through plates 452 are symmetrically arranged with the extension tube 451 as the center, the through plate 452 penetrates the extension tube 451 and extends to the outside thereof, a round rod 454 is fixedly installed in the middle of the outer surface of the through plate 452, a mounting block 458 is fixedly installed inside the round rod 454, rotating rods 455 are rotatably installed on both sides of the outer surface of the mounting block 458, connecting rods 456 are fixedly installed on the outer surface of the connecting rod 456, and inner arc pads 457 are fixedly installed on the outer surface of the connecting rod 456. When the staff puts the metal hose on the surface of the inner arc pad 457, the inner arc pad 457 adjusts the position of the rotating rod 455 according to the inner diameter of the metal hose, so that the rotating rod 455 drives the connecting rod 456 to rotate on both sides of the mounting block 458. Since the connecting rods 456 are installed at both ends of the inner arc pad 457, the two connecting rods 456 stretch the inner arc pad 457 when they rotate, so that multiple groups of inner arc pads 457 can support the metal hose according to the inner diameter of the metal hose, so as to support and shape the metal hose and avoid deformation of the thin-walled metal hose during welding, affecting the welding effect.

[0049] The extension tube 451 is fixedly mounted on the outer surface of the extension rod 44 , and the inner arc pad 457 is made of a flexible material, and the inner arc pad 457 is attached to the inner wall of the metal hose.

[0050] During use, when the staff is welding the metal hose, it is necessary to weld the metal hose and the joint. The staff adjusts the position of the positioning component 2 and the slide seat 5 in the guide rail 6 according to the position of the welding component 3, and clamps and fixes the metal hose and the joint respectively through the positioning component 2 and the clamping inner support component 4. The clamping inner support component 4 clamps the joint and supports the inside of the metal hose at the same time to stably support the welding position of the metal hose, and prevents the joint from being set on the outside of the metal hose and being welded by the welding component 3. The hose in the joint is easily deformed and cannot fit with the inner wall of the joint, resulting in deviation in the welding point.

[0051] When welding the metal hose and the joint, the staff will put the joint on the outside of the support member 45 and move the joint into the clamping member 46, so that the clamping member 46 clamps the joint. After the joint is clamped and fixed, the staff will adjust the position of the slide 5, so that the slide 5 drives the clamping inner support component 4 to move toward the position of the positioning component 2. At this time, the support member 45 is located on the outside of the positioning component 2, and then the staff will pass the metal hose through the positioning component 2 and put it on the surface of the support member 45. The support member 45 supports the inside of the metal hose while the metal hose is connected to the joint to facilitate subsequent welding work.

[0052] When the staff puts the metal hose on the surface of the inner arc pad 457, the inner arc pad 457 adjusts the position of the rotating rod 455 according to the inner diameter of the metal hose, so that the rotating rod 455 drives the connecting rod 456 to rotate on both sides of the mounting block 458. Since the connecting rods 456 are installed at both ends of the inner arc pad 457, the two connecting rods 456 stretch the inner arc pad 457 when they rotate, so that multiple groups of inner arc pads 457 can support the metal hose according to the inner diameter of the metal hose, so as to support and shape the metal hose and avoid deformation of the thin-walled metal hose during welding, affecting the welding effect.

[0053] After the staff puts the joint on the outside of the extension rod 44, the joint is moved to the bottom of the bent frame 463. At this time, the joint squeezes the clamping piece 465, so that the clamping piece 465 and the squeezing pad 466 are deformed under the force and clamped on the outside of the joint, so as to flexibly clamp the joint from multiple angles to avoid deformation of the joint and the metal hose due to excessive clamping force.

[0054] When clamping and fixing the metal hose, the staff moves the clamping inner support assembly 4 to the outside of the clamp block 23, and the staff places the metal hose on top of the bottom support frame 27 and passes it through the rotating plate 24, so that the metal hose is sleeved on the surface of the support member 45, so that the inside of the metal hose is supported and shaped by the support member 45, and then the staff adjusts the position of the guide slider 25 according to the shape of the metal hose, so that the guide slider 25 drives the inner connecting plate 22 and the clamp block 23 to slide on the surface of the guide rod 26, and clamps the metal hose through the clamp block 23. When the welding head 37 welds the metal hose and the joint, the staff starts the rotating plate 24, so that the rotating plate 24 drives the metal hose clamped in the clamp block 23 to rotate. Since the inside of the metal hose fits against the support member 45, when the metal hose rotates, it drives the support member 45 and the extension rod 44 to rotate, thereby driving the joint clamped by the clamp member 46 on the outside of the extension rod 44 to rotate, so that the welding head 37 can fully weld the connection between the metal hose and the joint.

[0055] After the metal hose is fixed to the joint, the staff starts the driving component 31, so that the driving component 31 drives the connecting block 34 to rotate to drive the limiting frame 35 to rotate, so as to adjust the inclination angle of the welding head 37 so that the welding head 37 can weld the connection between the metal hose and the joint.
