Description

Technical Field

[0001] The present invention relates to the technical field of cable manufacturing, and in particular to a floating photovoltaic cable manufacturing device and a manufacturing method for an offshore photovoltaic system. Background Art

[0002] At present, offshore photovoltaic systems are developing rapidly. Setting up photovoltaic panels on the sea surface and then connecting them with photovoltaic cables to achieve photoelectric energy conversion is one of the very important development directions in the current new energy field. The difference between photovoltaic cables and ordinary cables is that ordinary cables need to meet other effects such as signal transmission, while photovoltaic cables only need to achieve energy transmission, similar to the existence of wires. At present, photovoltaic cables used in such environments mostly need to add an armor layer on the inside of the cable to improve the overall corrosion resistance, sealing and stress resistance of the cable body. Therefore, the preparation processes of photovoltaic cables and ordinary cables are different.

[0003] In the prior art, there are obvious defects in the packaging process of photovoltaic cable armor. The armor is mostly made of steel sheets or steel wires, which are aligned and wound on the insulating layer inside the cable body. The armor needs to be cut and welded at specific positions. This will result in that during normal processing, once the force on one side of the armor disappears (here refers to the armor tape being cut, the armor tape being insufficient, etc.), the armor wound on the surface of the cable body will become loose under the action of torsional force, resulting in armoring failure. In serious cases, there will be safety hazards. The traditional solution is to manually weld the armor gaps, which not only seriously wastes labor, but also is inconvenient and unsafe to operate.

[0004] Therefore, how to provide a floating photovoltaic cable manufacturing device and a manufacturing method for an offshore photovoltaic system is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] One object of the present invention is to provide a floating photovoltaic cable manufacturing device and a manufacturing method for an offshore photovoltaic system.

[0006] According to an embodiment of the present invention, a manufacturing device and method for a floating photovoltaic cable for an offshore photovoltaic system includes a cable body passing through a rack at a constant speed, a winding frame is rotatably arranged on a motion path close to the cable body on one side of the rack, the winding frame is connected to a drive motor through a transmission mechanism, and the rotation of the winding frame drives the armored steel sheet to be wound around the surface of the cable body;

[0007] A spot welding gun, wherein the spot welding gun is movably arranged inside the frame above the cable body through an adjusting mechanism, and the lower part of the spot welding gun is aligned with the armored steel sheet on the surface of the cable body. The adjusting mechanism comprises a quadruple toothed belt assembly and a reciprocating assembly, and the lower part of the quadruple toothed belt assembly is connected to the output shaft of the driving motor through a pulley, and one side of the pulley above the quadruple toothed belt assembly is movable on the inner side of the frame through a sleeve, and the driving motor drives the reciprocating assembly to rotate inside the frame through the quadruple toothed belt assembly, and the reciprocating assembly comprises a turntable and a pushing slide, and a bump shaft is fixed on one side of the turntable, and the bump shaft is slidably arranged on the inner side of the pushing slide, and the rotation of the turntable drives the pushing slide through the bump shaft The cam is connected to the drive shaft by a spring, and the cam is connected to the drive shaft by a spring.

[0008] The resistance belt is sleeved on the surfaces of the two groups of driving shafts, and the resistance belt is in contact with the armored steel sheets on the upper and lower sides of the cable body. The movement of the cable body realizes the rotation of the driving shaft on both sides of the connecting frame.

[0009] Furthermore, a pressing frame mechanism is arranged on the surface of the armored steel sheet near the spot welding gun, axial holes are provided on both sides of the connecting frame and are movably connected to the driving shaft, the surface of the connecting frame is elastically connected to the frame by setting a spring part, and the resistance band is tightly attached to the surface of the armored steel sheet through the spring part.

[0010] Furthermore, both sides of the single group of driving shafts are respectively connected to the belt transmission assembly, and one side of the belt transmission assembly is movably connected to the rotation amount monitor through the pulley shaft.

[0011] Furthermore, one side of the rotation amount monitor is connected to the inner surface of the frame by transverse sliding through an elastic slider, and the rotation amount monitor is electrically connected to the driving motor.

[0012] Furthermore, the transmission mechanism includes main teeth, auxiliary teeth and a gear ring, the main teeth and the gear ring are respectively engaged with the upper and lower sides of the auxiliary teeth, the main teeth are fixed to the output shaft of the driving motor, and the gear ring is opened on one side of the winding frame.

[0013] The manufacturing method of the floating photovoltaic cable for the offshore photovoltaic system comprises the following specific steps:

[0014] S1. The cable body passes through the frame and the axis centerline position of the winding frame at a constant speed, and at the same time, the driving motor drives the winding frame to rotate on one side of the frame through the meshing transmission of the main gear, the auxiliary gear and the gear ring. At this time, the armored steel sheets on both sides of the winding frame can be wound to achieve the twisting of the armor on the surface of the cable body;

[0015] S2. When the armored steel sheet wound on the surface of the cable body moves to the position of the pressing frame mechanism with the cable body, the resistance belt is sleeved on the surfaces of the two sets of driving shafts, and the driving shafts are connected to each other through the connecting frame. In this way, the spring member on the surface of the connecting frame can provide a downward pressure to the connecting frame, driving the resistance belt to be in close contact with the surface of the armored steel sheet. At this time, the continuous movement effect of the cable body can realize the rotation of the driving shaft through the resistance belt, and at the same time, the tight contact effect of the resistance belt on the armored steel sheet effectively prevents the armored steel sheet from loosening;

[0016] S3. When the driving shaft is driven to rotate, the two sides thereof can transmit the rotation effect to the rotation amount monitor through the belt transmission assembly, and the rotation amount monitor detects the rotation amount to judge the actual movement speed of the armored steel sheet on the surface of the cable body, thereby feeding back the signal to the driving motor to control the actual speed of the driving motor and prevent the armored steel sheet from being folded due to excessive speed of the driving motor;

[0017] S4. While driving the frame to rotate, the driving motor can drive the limiting slide bar on the upper inner side of the frame to rotate through the four-link toothed belt assembly. A turntable is fixed on one side of the limiting slide bar. The rotation of the turntable causes the convex block shaft on one side of the surface to rotate, pushing the slide bar to reciprocate up and down under the force, thereby driving the spot welding gun to move up and down, and starting the spot welding gun at the specified position, so that the welding point below the spot welding gun contacts the gap on the surface of the armored steel sheet, and the spot welding operation is realized during the movement under the action of the torsion spring. Finally, the threaded adjustment rod can be rotated, and the threaded adjustment rod can move threadedly and push the limiting slide bar under the support of the movable connection of the limiting convex ring, so that the reciprocating assembly as a whole drives the spot welding gun to move horizontally, changing the position of the welding point below the spot welding gun. At the same time, the connecting slide bar slides on the surface of the stable slide bar, and the bolt is tightened after the position is determined.

[0018] The beneficial effects of the present invention are:

[0019] The present invention arranges a quadruple toothed belt assembly on the output shaft of the driving motor. When the driving motor drives the winding frame to rotate to wrap the armored steel sheet on the surface of the cable body, the reciprocating assembly can also synchronously drive the spot welding gun to move up and down. When the spot welding gun contacts the gap on the surface of the wound armored steel sheet, the spot welding operation can be realized. At the same time, under the support of the elastic torsion of the torsion spring, the contact position between the lower part of the spot welding gun and the armored steel sheet can move laterally in a small range, so as to better adapt to the cable body in the moving state, greatly improve the production efficiency, and reduce the output of labor.

[0020] The present invention provides a limit slide bar on one side of the turntable, and a limit slide can occur between the limit slide bar and the upper pulley of the quadruple toothed belt assembly. When the threaded adjustment rod is twisted, one side of the threaded adjustment rod can effectively resist the limit slide bar to move horizontally, thereby pushing the reciprocating assembly and the spot welding gun as a whole to shift, thereby changing the contact position between the lower side of the spot welding gun and the armored steel sheet, thereby adapting to the spot welding operation of armored steel sheets of different widths, and stabilizing the movement effect of the spot welding gun by the stable sliding effect of the stable slide bar, further improving the spot welding accuracy, so that the armored steel sheet can be better wrapped around the cable body surface, and preventing the armored steel sheet from becoming loose in the middle after the force on one side of the armored steel sheet disappears;

[0021] The present invention arranges a pressing frame mechanism at a position near the spot welding gun on the inner side of the frame, so that the resistance belt can be fitted with the upper and lower sides of the armored steel sheet under the sleeve arrangement of the two sets of driving shafts, and the connecting frame is elastically connected to the frame through a spring member, so that the resistance belt can be well fitted with the armored steel sheet, further preventing the armored steel sheet from loosening;

[0022] The present invention provides a resistance band. The elastic effect of the spring member can not only make the resistance band close to the armored steel sheet, but also the movement effect of the cable body can drive the resistance band as a whole to move on the surface of the driving shaft through the close contact between the armored steel sheet and the resistance band. In this way, the driving shaft can rotate, and one side of the driving shaft is connected to a rotation amount monitor through a belt transmission assembly. The rotation amount monitor can monitor the rotation speed of the driving shaft in real time, so as to control the driving motor or feedback the actual movement amount signal, so that the overall independence of the device is strong, and it can have higher control and adjustment capabilities without relying on the assistance of other external devices.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0036] refer to Figure 1 and Figure 2 , including a cable body 2 passing through a frame 1 at a constant speed, a winding frame 3 is rotatably arranged on one side of the frame 1 close to the moving path of the cable body 2, the winding frame 3 is connected to a driving motor 4 through a transmission mechanism 6, and the rotation of the winding frame 3 drives the armored steel sheet 5 to be wound on the surface of the cable body 2;

[0037] A spot welding gun 7, which is movably arranged above the cable body 2 inside the frame 1 through an adjustment mechanism 8, and the lower side of the spot welding gun 7 is aligned with the armored steel sheet 5 on the surface of the cable body 2;

[0038] The resistance belt 91 is sleeved on the surfaces of two sets of driving shafts 92 . The resistance belt 91 is in contact with the armored steel sheets 5 on the upper and lower sides of the cable body 2 . The movement of the cable body 2 drives the shafts 92 to rotate on both sides of the connecting frame 93 .

[0039] In this embodiment, the cable body 2 passes through the inner side of the frame 1 during the extrusion process, and the driving motor 4 in the driving state can drive the winding frame 3 to rotate through the transmission mechanism 6, and armored steel sheets 5 are respectively set on both sides of the winding frame 3, and the armored steel sheets 5 are wound around the surface of the cable body 2, so that the basic armor winding operation can be realized. At this time, the armored steel sheet 5 has a large torsional stress. When the armored steel sheet 5 moves with the cable body 2 to the position of the resistance band 91, the driving shaft 92 can better press the upper and lower sides of the armored steel sheet 5 to reduce the existence of torsional force. Then the armored steel sheet 5 moves to the bottom of the spot welding gun 7. Under the transmission connection effect of the adjustment mechanism 8 and the driving motor 4, the spot welding gun 7 is driven to reciprocate up and down inside the frame 1, so as to realize the contact between the welding point below the spot welding gun 7 and the gap position between the armored steel sheet 5, thereby realizing the spot welding operation and preventing the armored steel sheet 5 from loosening.

[0040] refer to Figure 4 and Figure 7 The adjustment mechanism 8 includes a four-link toothed belt assembly 81 and a reciprocating assembly 83. The lower part of the four-link toothed belt assembly 81 is connected to the output shaft of the driving motor 4 through a pulley. One side of the pulley above the four-link toothed belt assembly 81 moves on the inner side of the frame 1 through a sleeve. The driving motor 4 drives the reciprocating assembly 83 to rotate on the inner side of the frame 1 through the four-link toothed belt assembly 81.

[0041] In this embodiment, the quadruple toothed belt assembly 81 refers to a belt transmission structure composed of four sets of pulleys and toothed belts. A pressure wheel can also be set on the surface of the toothed belt to improve the transmission effect. One side of the pulley above the quadruple toothed belt assembly 81 is movably connected to the frame 1 through a shaft sleeve to achieve active limiting and satisfy the subsequent connection operation of the limiting slide bar 82. In this way, the transmission effect of the drive motor 4 can effectively drive the reciprocating assembly 83 to rotate through the quadruple toothed belt assembly 81, thereby driving the spot welding gun 7 to reciprocate up and down.

[0042] refer to Figure 4 , Figure 5 and Figure 8 The reciprocating assembly 83 includes a rotating disk 831 and a pushing slide 833. A lug shaft 832 is fixed to one side of the rotating disk 831. The lug shaft 832 is slidably arranged inside the pushing slide 833. The rotating disk 831 drives the pushing slide 833 to move up and down through the lug shaft 832. One side of the pushing slide 833 is movably connected to the spot welding gun 7 through the shaft seat, and both sides of the spot welding gun 7 are elastically connected to the shaft seat of the pushing slide 833 through the torsion spring 84. A connecting slide 85 slidably connected to the stabilizing slide 86 is fixed above the pushing slide 833. The connecting slide 85 is limited by the pressing frame bolt and the stabilizing slide 86. Both sides of the stabilizing slide 86 slide up and down in the slide groove inside the frame 1.

[0043] When the spot welding gun 7 rotates on the surface of the push slide 833, the torsion spring 84 can provide an elastic torsion effect, so that the spot welding gun 7 can adapt to the cable body 2 in the moving state, thereby meeting the requirements of the spot welding operation.

[0044] refer to Figure 4 , Figure 5 and Figure 8 A limiting slide bar 82 is fixed on one side of the turntable 831, and the limiting slide bar 82 slides through the axial center line position of the quadruple toothed belt assembly 81. One side of the limiting slide bar 82 is fixedly connected to a limiting convex ring 88, and one side of the limiting convex ring 88 is rotationally limitedly connected to a threaded adjustment rod 87, and one side of the threaded adjustment rod 87 is threadedly connected to the frame 1 through the tooth pattern.

[0045] In the present embodiment, the connection mode between the limit slide bar 82 and the shaft sleeve on one side of the quadruple toothed belt assembly 81 is a sliding connection, and a spline connection is maintained between each other, thereby satisfying the transmission of the rotation effect, and a limit convex ring 88 is fixed on one side of the limit slide bar 82, and the limit convex ring 88 can maintain the connection effect with the threaded adjustment rod 87 while satisfying the rotation effect. In this way, when the threaded adjustment rod 87 rotates, the limit convex ring 88 can resist the limit slide bar 82 and move to one side, thereby driving the reciprocating assembly 83 and the spot welding gun 7 to move horizontally, changing the position of the welding point below the spot welding gun 7, so as to adapt to the gap welding operation of armored steel sheets 5 of different widths.

[0046] refer to Figure 2 , Figure 6 and Figure 8 A pressing frame mechanism 9 is provided on the surface of the armored steel sheet 5 near the spot welding gun 7. Axial holes are provided on both sides of the connecting frame 93 to be movably connected with the driving shaft 92. The surface of the connecting frame 93 is elastically connected to the frame 1 by setting a spring member 94. The resistance band 91 is tightly attached to the surface of the armored steel sheet 5 through the spring member 94. Both sides of the single group of driving shafts 92 are respectively connected to the belt transmission assembly 95, and one side of the belt transmission assembly 95 is movably connected to the rotation amount monitor 96 through the pulley shaft. One side of the rotation amount monitor 96 is lateral slidingly connected to the inner surface of the frame 1 through an elastic slider, and the rotation amount monitor 96 is electrically connected to the driving motor 4.

[0047] In this embodiment, under normal circumstances, the resistance band 91 is in contact with the armored steel sheet 5 wrapped around the surface of the cable body 2, and the driving shaft 92 is arranged at both ends of the inner side of the resistance band 91 to provide support for the resistance band 91. The driving shaft 92 is elastically connected to the frame 1 through the connecting frame 93 and the spring member 94, so that the resistance band 91 can elastically press against the surface of the armored steel sheet 5 to prevent the armored steel sheet 5 from loosening. When the cable body 2 drives the armored steel sheet 5 to move, the resistance band 91 will be driven synchronously to realize the rotation of the driving shaft 92, and one side of the driving shaft 92 is connected to the rotation amount monitor 96 through the belt transmission assembly 95. The rotation amount monitor 96 monitors the movement speed of the resistance band 91 in real time, thereby controlling the speed of the drive motor 4, so that the overall independence of the device is strong and it can be used alone without external settings.

[0048] refer to Figure 2 , Figure 6 and Figure 8 The transmission mechanism 6 includes a main tooth 61, a secondary tooth 62 and a ring gear 63. The main tooth 61 and the ring gear 63 are respectively engaged with the upper and lower sides of the secondary tooth 62. The main tooth 61 is fixed to the output shaft of the driving motor 4, and the ring gear 63 is opened on one side of the winding frame 3.

[0049] In this embodiment, the transmission connection effect of the main teeth 61 , the auxiliary teeth 62 and the gear ring 63 enables the driving motor 4 to normally drive the winding frame 3 to flip on one side of the frame 1 , thereby realizing the winding operation of the armored steel sheet 5 on the surface of the cable body 2 .

[0050] The manufacturing method of the floating photovoltaic cable for the offshore photovoltaic system comprises the following specific steps:

[0051] S1, by passing the cable body 2 through the frame 1 and the axis centerline position of the winding frame 3 at a constant speed, and at the same time driving the motor 4 to drive the winding frame 3 to rotate on one side of the frame 1 through the meshing transmission of the main teeth 61, the auxiliary teeth 62 and the gear ring 63, at this time, the armored steel sheets 5 on both sides of the winding frame 3 can be wound to achieve the twisting of the armor on the surface of the cable body 2;

[0052] S2, when the armored steel sheet 5 wound on the surface of the cable body 2 moves to the position of the pressing frame mechanism 9 with the cable body 2, the resistance belt 91 is sleeved on the surfaces of the two sets of driving shafts 92, and the driving shafts 92 are connected to each other through the connecting frame 93, so that the spring member 94 on the surface of the connecting frame 93 can provide a downward pressure to the connecting frame 93, driving the resistance belt 91 to be in close contact with the surface of the armored steel sheet 5. At this time, the continuous movement effect of the cable body 2 can be realized by the resistance belt 91 to drive the shaft 92 to rotate, and at the same time, the resistance belt 91 can effectively prevent the armored steel sheet 5 from loosening due to its close contact with the armored steel sheet 5;

[0053] S3, when the driving shaft 92 is driven to rotate, the two sides thereof can transmit the rotation effect to the rotation amount monitor 96 through the belt transmission assembly 95, and the rotation amount monitor 96 detects the rotation amount to judge the actual movement speed of the armored steel sheet 5 on the surface of the cable body 2, thereby feeding back a signal to the driving motor 4 to control the actual rotation speed of the driving motor 4, so as to prevent the armored steel sheet 5 from being wound up due to excessive rotation speed of the driving motor 4;

[0054] S4, the driving motor 4 can drive the limiting slide bar 82 on the upper inner side of the frame 1 to rotate through the quadruple toothed belt assembly 81 while driving the winding frame 3 to rotate. A turntable 831 is fixed on one side of the limiting slide bar 82. The rotation of the turntable 831 causes the protruding block shaft 832 on one side of the surface to rotate, pushing the slide bar 833 to be forced to reciprocate up and down, thereby driving the spot welding gun 7 to move up and down, starting the spot welding gun 7 at the specified position, so that the welding point below the spot welding gun 7 contacts the gap on the surface of the armored steel sheet 5. At the same time, the spot welding operation is realized during the movement under the action of the torsion spring 84. Finally, the threaded adjustment rod 87 can be rotated. The threaded adjustment rod 87 moves threadably and can push the limiting slide bar 82 under the support of the movable connection of the limiting protruding ring 88, so that the reciprocating assembly 83 as a whole drives the spot welding gun 7 to move horizontally, changing the position of the welding point below the spot welding gun 7. At the same time, the connecting slide bar 85 slides on the surface of the stabilizing slide bar 86, and the bolt is tightened after the position is determined.

[0055] Working principle: First, the cable body 2 passes through the center of the frame 1 and the winding frame 3 during the extrusion process. When the driving motor 4 is driven, the winding frame 3 can be driven to rotate through the transmission effect of the main teeth 61, the auxiliary teeth 62 and the gear ring 63 in the transmission mechanism 6. The armored steel sheets 5 on both sides of the winding frame 3 cover the surface of the cable body 2 during the rotation process. When the armored steel sheets 5 wound on the surface of the cable body 2 pass through the resistance belt 91 position in the pressing frame mechanism 9, the resistance belt 91 is connected to the spring member through the driving shaft 92 and the connecting frame 93. 94 is elastically connected, so that the resistance belt 91 has an elastic pressure, so as to better press the surface of the armored steel sheet 5 to prevent the armored steel sheet 5 from loosening. At the same time, the armored steel sheet 5 moves with the cable body 2 to drive the resistance belt 91 to move, so that the driving shaft 92 in the rotating state can transmit the rotation effect to the rotation amount monitor 96 through the belt transmission component 95. The rotation amount monitor 96 monitors the rotation amount in real time to control the speed of the drive motor 4 and improve the independence of the device. Then the armored steel sheet 5 moves to the bottom of the spot welding gun 7. At the same time, because the driving motor 4 drives the limiting slide bar 82 to rotate through the four-link toothed belt assembly 81 in the adjusting mechanism 8, one side of the limiting slide bar 82 is directly connected to the turntable 831, so that the turntable 831 in the rotating state can effectively drive the convex shaft 832 to rotate, pushing the slide 833 to move up and down under the force, and at the same time drives the spot welding gun 7 to move up and down until the spot welding gun 7 contacts the gap on the surface of the armored steel sheet 5 to achieve spot welding. At the same time, under the torsion connection of the torsion spring 84, the spot welding gun 7 can rotate in a small range, so that it can cooperate with The movement operation of the armored steel sheet 5 is finally carried out by rotating the threaded adjustment rod 87. The threaded adjustment rod 87 moves horizontally in the frame 1. Under the connection of the limiting convex ring 88, the limiting slide bar 82 is displaced, which resists the overall movement of the reciprocating assembly 83 and the spot welding gun 7. At the same time, the connecting slide bar 85 moves on the surface of the stabilizing slide bar 86. After reaching the specified position, the connecting slide bar 85 is fixed to the stabilizing slide bar 86 by a tightening bolt, so that the spot welding gun 7 can be spot welded with armored steel sheets 5 of different widths, and has a strong adaptability.

6. A method for manufacturing a floating photovoltaic cable for an offshore photovoltaic system, using the floating photovoltaic cable manufacturing device for an offshore photovoltaic system according to claim 5, characterized in that: The specific steps are as follows: S1, the cable body (2) is passed through the frame (1) and the axis centerline position of the winding frame (3) at a constant speed, and at the same time, the driving motor (4) drives the winding frame (3) to rotate on one side of the frame (1) through the meshing transmission of the main teeth (61), the auxiliary teeth (62) and the gear ring (63), and at this time, the armored steel sheets (5) on both sides of the winding frame (3) are wound and connected to realize the twisting of the armor on the surface of the cable body (2); S2, when the armored steel sheet (5) wound on the surface of the cable body (2) moves to the position of the pressing frame mechanism (9) following the cable body (2), the resistance band (91) is sleeved on the surfaces of the two sets of driving shafts (92), and the driving shafts (92) are connected to each other through the connecting frame (93), so that the spring member (94) on the surface of the connecting frame (93) can provide a downward pressure to the connecting frame (93), driving the resistance band (91) to be in close contact with the surface of the armored steel sheet (5). At this time, the continuous movement effect of the cable body (2) can realize the rotation of the driving shaft (92) through the resistance band (91), and at the same time, the close contact effect of the resistance band (91) on the armored steel sheet (5) effectively prevents the armored steel sheet (5) from loosening; S3, when the driving shaft (92) is driven to rotate, the two sides thereof can transmit the rotation effect to the rotation amount monitor (96) through the belt transmission assembly (95), and the rotation amount monitor (96) detects the rotation amount to judge the actual movement speed of the armored steel sheet (5) on the surface of the cable body (2), thereby feeding back a signal to the driving motor (4), controlling the actual rotation speed of the driving motor (4), and preventing the armored steel sheet (5) from being overlapped due to the driving motor (4) rotating too fast; S4, the driving motor (4) can drive the upper limit slide bar (82) on the inner side of the frame (1) to rotate through the quadruple toothed belt assembly (81) while driving the winding frame (3) to rotate. A turntable (831) is fixed on one side of the limit slide bar (82). The turntable (831) rotates so that the protruding block shaft (832) on one side of the turntable (831) rotates, pushing the slide bar (833) to reciprocate up and down under force, thereby driving the spot welding gun (7) to move up and down, starting the spot welding gun (7) at a specified position, so that the welding point below the spot welding gun (7) is connected to the armored steel sheet. (5) The spot welding operation is realized in the process of movement under the action of the torsion spring (84), and finally, the threaded adjustment rod (87) is rotated, the threaded adjustment rod (87) is threadedly moved, and the limit slide rod (82) can be pushed under the support of the movable connection of the limit convex ring (88), so that the reciprocating assembly (83) drives the spot welding gun (7) to move horizontally as a whole, and the position of the welding point under the spot welding gun (7) is changed. At the same time, the connecting slide rod (85) slides on the surface of the stabilizing slide rod (86), and the bolt is tightened after the position is determined.
