Description

Technical Field

[0001] This invention relates to the field of welding technology for mining flat welded wire mesh, specifically to a welding positioning device for mining flat welded wire mesh. Background Technology

[0002] Mining welded wire mesh is a specialized metal mesh material used for support and safety protection in underground mines. It is primarily made from low-carbon steel wire, galvanized steel wire, or plastic-coated steel wire, manufactured through a cross-welding process. Various mesh sizes are available, and wire diameters are selected based on load-bearing requirements. The overall weld is strong and resistant to breakage. Its core function is to enhance the stability of surrounding rock. It can be widely used for sidewall / roof support in underground roadways, roof protection in working faces, goaf isolation, and coal chute protection. It effectively prevents rockfalls and rockfalls, ensuring safe mining operations. The galvanizing or plastic coating treatment gives it moisture resistance and corrosion resistance, making it suitable for the harsh environment of high humidity and dust in underground mines.

[0003] Mining flat welded wire mesh is a core metal mesh material for underground mine support and safety protection. The raw materials include low-carbon steel wire, galvanized steel wire, and plastic-coated steel wire. The wire diameter needs to be selected according to load-bearing requirements (typically 3-8mm), and the mesh size must also be adapted to specific protection scenarios, requiring extremely high compatibility with processing equipment. Currently, most mainstream welding positioning devices are designed with fixed specifications, exhibiting two major limitations: firstly, the clamping component parameters are fixed, making it unable to adapt to steel wires of different diameters (3-8mm), and easily damaging galvanized / plastic-coated steel wires, resulting in poor compatibility; secondly, there is a lack of standard positioning benchmarks and precision adjustment mechanisms, with clamping accuracy > ±1.5mm, far exceeding the industry standard of ±0.5mm, making it difficult to meet the precise welding requirements of intersections. Therefore, we propose a welding positioning device for mining flat welded wire mesh. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a welding positioning device for mining flat welded wire mesh, which solves the problems that existing mining flat welded wire mesh welding positioning devices are mostly designed with fixed specifications and fixed clamping component parameters, which cannot adapt to steel wires with different diameters of 3-8mm, are prone to damaging galvanized / plastic-coated steel wires, and have poor adaptability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding positioning device for mining flat welded wire mesh, comprising a body, a panel, an inspection door, and a steel wire strip. The panel is fixedly connected to the upper surface of the body, the inspection door is installed on the inner wall of the body, the steel wire strip is placed on the upper surface of the panel, and adjustment devices are provided on both the left and right sides of the body. An assembly device is provided at the drive end of the adjustment device. The assembly device includes a mounting frame one and a mounting frame two, and clamping devices are provided on the surfaces of both mounting frame one and mounting frame two.

[0006] The clamping device includes a positioning component, which includes a U-shaped frame. The U-shaped frame is sleeved on the surface of the mounting frame. A locking bolt is threaded onto the inner wall of the U-shaped frame. A lifting frame is fixedly connected to the upper surface of the U-shaped frame. A limiting frame is fixedly connected to the upper surface of the lifting frame. A clamping frame is rotatably connected to the inner wall of the limiting frame. A limiting spring is fixedly connected to the upper surface of the lifting frame. The limiting spring is fixedly connected to the surface of the clamping frame. A clamping plate is installed on the inner wall of the clamping frame. A threaded hole is opened on the arc surface of the clamping frame. A fixing bolt is threaded onto the inner wall of the clamping frame located in the threaded hole. A slot is opened on the outer arc surface of the clamping plate. The fixing bolt is inserted into the inner wall of the slot.

[0007] The clamping device also includes a constraint assembly, which consists of a connecting frame, a sleeve, a cover plate, a T-shaped locking pin, a protrusion, a compression spring, a connecting post, and a knob.

[0008] Preferably, the constraint assembly includes a connecting frame, which is fixedly connected to the side surface of the U-shaped frame. A sleeve is fixedly connected to the side surface of the connecting frame, and a cover plate is fixedly connected to the surface of the sleeve. A T-shaped locking pin is installed on the inner wall of the sleeve, and a protrusion is fixedly connected to the arc surface of the T-shaped locking pin. A guide cavity adapted to the protrusion is opened on the surface of the sleeve, and the protrusion is slidably connected to the inner wall of the guide cavity. A compression spring is fixedly connected to the inner wall of the connecting frame, and the side of the compression spring away from the connecting frame abuts against the surface of the T-shaped locking pin. A connecting post is fixedly connected to the side of the T-shaped locking pin away from the connecting frame, and a knob is fixedly connected to the surface of the connecting post. By means of the matching and cooperation between the guide cavity on the inner wall of the sleeve and the arc surface protrusion of the T-shaped locking pin, the position of the T-shaped locking pin can be simultaneously limited and locked while the compression spring applies an elastic force to the T-shaped locking pin, thereby stably restricting the T-shaped locking pin to the insertion working state.

[0009] Preferably, an acrylic plate is fixedly connected to the side surface of the U-shaped frame. The surface of the acrylic plate has a groove, and an identification strip is fixedly connected to the inner wall of the groove. The acrylic plate is movably abutted against the inner side of the first mounting frame. Both the first and second mounting frames have scale markings on their inner sides. By utilizing the movable abutment between the acrylic plate and the inner side of the first mounting frame, and the corresponding adaptation of the identification strip on the inner wall of the acrylic plate groove with the scale markings on the inner sides of the first and second mounting frames, precise control of the spacing between multiple clamping devices can be achieved simultaneously while the user adjusts the position of the clamping device.

[0010] Preferably, the locking bolt abuts against the upper surface of the first mounting frame, the upper surface of the lifting frame has a round hole adapted to the locking bolt, the clamping plate abuts against the surface of the steel wire, and the outer arc surface of the clamping plate is provided with an insertion part, which is inserted into the inner wall of the clamping frame; by tightening the locking bolt, it abuts tightly against the upper surface of the first mounting frame, thereby locking the position of the U-shaped frame that is already limited on the first mounting frame, thus ensuring that the first mounting frame and the associated structure above it are fixed in the designated position, and combined with the abutment between the clamping plate and the surface of the steel wire, finally achieving stable clamping and support for the steel wire.

[0011] Preferably, both mounting bracket one and mounting bracket two have grooves on their surfaces. The T-shaped pin is slidably connected to the inner wall of the connecting bracket and to the inner wall of the groove. The depth of the groove is greater than the insertion length of the T-shaped pin. The cover plate is fitted onto the surface of the connecting column. By means of the matching sliding connection between the T-shaped pin and the grooves on the surfaces of mounting bracket one and mounting bracket two, the U-shaped frame can be constrained on mounting bracket one or mounting bracket two first. Subsequently, by tightening the locking bolts, the limiting effect of the T-shaped pin is further coordinated, ultimately achieving reliable double locking of the U-shaped frame position.

[0012] Preferably, the adjustment device includes an assembly frame, which is fixedly connected to the side surface of the machine body. A cylinder is fixedly connected to the surface of the assembly frame, a connecting frame is fixedly connected to the piston rod of the cylinder, a servo motor is fixedly connected to the side surface of the connecting frame, a coupling is fixedly connected to the shaft of the servo motor, a rotating shaft is fixedly connected to the surface of the coupling, and an assembly frame is fixedly connected to the side of the rotating shaft away from the coupling. Based on the fixed connection between the assembly frame and the side surface of the machine body, the cylinder can be stably assembled on the surface of the assembly frame. When the cylinder works, its piston rod can drive the connected connecting frame to rise and fall in the vertical direction. Then, through the fixed relationship of the side surface of the connecting frame, the servo motor on the connecting frame and the rotating shaft connected to the servo motor shaft through the coupling, and the assembly frame fixed at the end of the rotating shaft away from the coupling, are driven synchronously. With the help of this transmission link, the clamping device connected to the assembly frame can be driven to rise and fall synchronously in the vertical direction, ultimately realizing the user's adjustment of the height of the clamping device.

[0013] Preferably, a positioning frame is fixedly connected to the inner wall of the connecting frame, and the rotating shaft is rotatably connected to the inner wall of the positioning frame. Relying on the rotational connection between the positioning frame fixed to the inner wall of the connecting frame and the rotating shaft, the positioning frame can provide reliable radial support for the rotating shaft, ensuring the coaxiality and operational stability of the rotating shaft when it rotates under the drive of the servo motor. On the other hand, it can transmit the radial force borne by the rotating shaft during rotation to the connecting frame through the positioning frame, thereby effectively reducing the load borne by the rotating shaft itself, reducing its operating load, and further ensuring the stable operation of the rotating shaft and the entire transmission link.

[0014] Preferably, the upper surface of the assembly frame is provided with an assembly device, the assembly device including a mounting frame one, the mounting frame one being fixedly connected to the upper surface of the assembly frame, a guide rail being fixedly connected to the inner wall of the mounting frame one, a slider being slidably connected to the inner wall of the guide rail, a mounting frame two being fixedly connected to the surface of the slider, a storage cavity being formed on the surface of the mounting frame two, a top block being slidably connected to the inner wall of the storage cavity of the mounting frame two, a pressing block being fixedly connected to the side surface of the top block, a rubber gasket being fixedly connected to the surface of the pressing block, and a fixed... The fixed plate has a return spring fixedly connected to its surface, and the second mounting bracket has a restraining bolt threadedly connected to the inner wall of the storage cavity. Relying on the guide rail on the inner wall of the first mounting bracket, a sliding connection is formed with the slider fixed on the surface of the second mounting bracket, which can accurately guide the movement direction of the second mounting bracket. This mating structure can ensure that when the user operates the second mounting bracket, it can move stably along the trajectory defined by the guide rail, avoiding deviation, and providing a stable movement reference for the pressing block, top block and other components in the storage cavity of the second mounting bracket, thereby ensuring the positional accuracy when clamping and positioning is achieved through the pressing block, restraining bolt and other means.

[0015] Preferably, the surface of the slider has a square hole, the pressing block is slidably connected to the inner wall of the square hole, the pressing block is slidably connected to the inner wall of the receiving cavity, and the rubber gasket abuts against the inner wall of the guide rail. Relying on the dual adaptive sliding connection between the pressing block and the square hole of the slider and the receiving cavity of the second mounting frame, when the pressing block is pushed along the receiving cavity by the restraining bolt, the rubber gasket on the surface of the pressing block can form a tight abutment with the guide rail on the inner wall of the first mounting frame. The rubber gasket can effectively increase the static friction between the pressing block and the guide rail. Thus, in the locked state, in conjunction with the tightening force of the restraining bolt and the limiting effect of the guide rail, the second mounting frame can be reliably locked, preventing it from shifting during the clamping and positioning process, and further ensuring the positioning stability of the assembly device.

[0016] Preferably, the top block has a storage groove on its side surface, the fixing plate is located on the inner wall of the storage groove, the side of the return spring away from the fixing plate is fixedly connected to the inner wall of the storage groove, the top block has a through hole on its upper surface, the binding bolt is inserted into the inner wall of the through hole, and the top block has a chamfer on the inner wall of the through hole; when the binding bolt is tightened, the bolt can be smoothly inserted along the chamfered through hole on the upper surface of the top block and push the top block to move along the storage cavity, thereby compressing the return spring. In the locked state, the binding bolt can counteract the rebound force of the return spring, stably restricting the top block to the "pushing and pressing block" state, so that the pressing block is kept in close contact with the inner wall of the guide rail, and finally the pressing block is reliably locked, further fixing the position of the mounting bracket two and ensuring the positioning accuracy of the assembly device.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] 1. In this invention, by setting up a clamping device, the clamping device can be quickly adjusted within a specified range. At the same time, the user can install or remove the clamping device according to the specifications of the workpiece being processed, thereby making the clamping device adaptable to workpieces of different specifications, effectively expanding its applicable scenarios and significantly improving the processing adaptability of the clamping device.

[0019] 2. In this invention, by setting up an assembly device, the height of the clamping device on the second mounting frame can be flexibly adjusted according to the needs of steel wires of different specifications, and it can be adapted to the clamping structure on the first mounting frame. This effectively breaks the limitation of a single specification, improves the versatility of the clamping device, and further broadens its application range for steel wires of different specifications, ensuring processing adaptability.

[0020] 3. In this invention, by setting an adjustment device to controllably adjust the orientation of the steel wire, it is ensured that the steel wire intersection can form a double welding node on the front and back sides, which effectively improves the welding firmness and overall structural strength of the steel wire intersection, and further optimizes the continuity and convenience of the welding operation.

A clamping plate 719 is installed on the inner wall of the clamping frame 717. A threaded hole is opened on the arc surface of the clamping frame 717. A fixing bolt 7110 is threadedly connected to the inner wall of the clamping frame 717 located in the threaded hole. A slot is opened on the outer arc surface of the clamping plate 719. The fixing bolt 7110 is inserted into the inner wall of the slot.

[0044] The clamping device 7 also includes a constraint assembly 72, which consists of a connecting frame 721, a sleeve 722, a cover plate 723, a T-shaped pin 724, a protrusion 725, a compression spring 726, a connecting post 727, and a knob 728.

[0045] The constraint assembly 72 includes a connecting frame 721, which is fixedly connected to the side surface of a U-shaped frame 711. A sleeve 722 is fixedly connected to the side surface of the connecting frame 721, and a cover plate 723 is fixedly connected to the surface of the sleeve 722. A T-shaped locking pin 724 is installed on the inner wall of the sleeve 722, and a protrusion 725 is fixedly connected to the arc surface of the T-shaped locking pin 724. A guide cavity adapted to the protrusion 725 is opened on the surface of the sleeve 722, and the protrusion 725 is slidably connected to the inner wall of the guide cavity. A compression spring 726 is fixedly connected to the inner wall of the connecting frame 721. The side of the spring 726 away from the connecting frame 721 abuts against the surface of the T-shaped locking pin 724. The side of the T-shaped locking pin 724 away from the connecting frame 721 is fixedly connected to the connecting post 727, and the surface of the connecting post 727 is fixedly connected to the knob 728. With the help of the matching and cooperation between the guide cavity of the inner wall of the sleeve 722 and the arc protrusion 725 of the T-shaped locking pin 724, the position limit and locking of the T-shaped locking pin 724 can be realized simultaneously while the spring 726 applies an elastic force to the T-shaped locking pin 724, thereby stably restricting the T-shaped locking pin 724 to the insertion working state.

[0046] An acrylic plate 713 is fixedly connected to the side surface of the U-shaped frame 711. The surface of the acrylic plate 713 has a groove.

The inner sides of both the mounting frame 61 and the mounting frame 64 are provided with scale markings. With the movable contact between the acrylic plate 713 and the inner side of the mounting frame 61, and the corresponding matching of the identification strip 714 on the inner wall of the groove of the acrylic plate 713 with the scale markings on the inner sides of the mounting frame 61 and the mounting frame 64, precise control of the distance between multiple clamping devices 7 can be achieved simultaneously while the user adjusts the position of the clamping device 7.

[0047] The locking bolt 712 abuts against the upper surface of the mounting bracket 61, the upper surface of the lifting bracket 715 has a round hole that matches the locking bolt 712, the clamping plate 719 abuts against the surface of the steel wire 4, and the outer arc surface of the clamping plate 719 is provided with an insertion part, which is inserted into the inner wall of the clamping bracket 717. By tightening the locking bolt 712, it abuts tightly against the upper surface of the mounting bracket 61, thereby locking the position of the U-shaped bracket 711 that is already limited on the mounting bracket 61, thus ensuring that the mounting bracket 61 and the related structure above it are fixed in the designated position. Combined with the abutment between the clamping plate 719 and the surface of the steel wire 4, the steel wire 4 is finally stably clamped and supported.

[0048] The surfaces of mounting bracket 1 61 and mounting bracket 2 64 are provided with sliding grooves.

The depth of the sliding grooves is greater than the insertion length of the T-shaped locking pins 724. Cover plate 723 is fitted onto the surface of connecting column 727. By means of the matching sliding connection between the T-shaped locking pins 724 and the sliding grooves on the surfaces of mounting bracket 1 61 and mounting bracket 2 64, the U-shaped frame 711 can be constrained on mounting bracket 1 61 or mounting bracket 2 64. Subsequently, by tightening the locking bolts 712, the limiting effect of the T-shaped locking pins 724 is further coordinated to achieve reliable double locking of the position of the U-shaped frame 711.

[0049] The adjustment device 5 includes an assembly frame 51, which is fixedly connected to the side surface of the machine body 1. A cylinder 52 is fixedly connected to the surface of the assembly frame 51. A connecting frame 53 is fixedly connected to the piston rod of the cylinder 52. A servo motor 55 is fixedly connected to the side surface of the connecting frame 53. A coupling 56 is fixedly connected to the shaft of the servo motor 55. A rotating shaft 57 is fixedly connected to the surface of the coupling 56. An assembly frame 58 is fixedly connected to the side of the rotating shaft 57 away from the coupling 56. Based on the fixed connection between the assembly frame 51 and the side surface of the machine body 1, the cylinder 52 can... Stably mounted on the surface of the assembly frame 51, when the cylinder 52 works, its piston rod can drive the connected connecting frame 53 to rise and fall in the vertical direction. Then, through the fixed relationship of the side surface of the connecting frame 53, the servo motor 55 on the connecting frame 53 is synchronously driven, as well as the rotating shaft 57 connected to the shaft of the servo motor 55 through the coupling 56, and the assembly frame 58 fixed at the end of the rotating shaft 57 away from the coupling 56. With the help of this transmission link, the clamping device 7 connected to the assembly frame 58 can be driven to rise and fall synchronously in the vertical direction, and finally realize the user's adjustment of the height of the clamping device 7.

[0050] The inner wall of the connecting frame 53 is fixedly connected to the positioning frame 54, and the rotating shaft 57 is rotatably connected to the inner wall of the positioning frame 54. Relying on the rotational connection between the positioning frame 54 fixed to the inner wall of the connecting frame 53 and the rotating shaft 57, the positioning frame 54 can provide reliable radial support for the rotating shaft 57, ensuring the coaxiality and operational stability of the rotating shaft 57 when it rotates under the drive of the servo motor 55. On the other hand, it can transmit the radial force borne by the rotating shaft 57 during rotation to the connecting frame 53 through the positioning frame 54, thereby effectively reducing the load borne by the rotating shaft 57 itself, reducing its operating load, and further ensuring the stable operation of the rotating shaft 57 and the entire transmission link.

[0051] The assembly frame 58 has an assembly device 6 on its upper surface. The assembly device 6 includes a mounting frame 61, which is fixedly connected to the upper surface of the assembly frame 58. A guide rail 62 is fixedly connected to the inner wall of the mounting frame 61, and a slider 63 is slidably connected to the inner wall of the guide rail 62. A mounting frame 64 is fixedly connected to the surface of the slider 63. A storage cavity 65 is formed on the surface of the mounting frame 64. A top block 66 is slidably connected to the inner wall of the storage cavity 65. A pressing block 67 is fixedly connected to the side surface of the top block 66, and a rubber gasket 68 is fixedly connected to the surface of the pressing block 67. A fixing plate 69 is fixedly connected to the inner wall of the storage cavity 65 of the mounting frame 64. A return spring 610 is fixedly connected to the surface of mounting bracket 69, and a restraining bolt 611 is threadedly connected to the inner wall of mounting bracket 64 in storage cavity 65. The guide rail 62 on the inner wall of mounting bracket 61 forms a matching sliding connection with the slider 63 fixed to the surface of mounting bracket 64, which can accurately guide the movement direction of mounting bracket 64. This mating structure can ensure that when the user operates mounting bracket 64, it can move stably along the trajectory defined by guide rail 62, avoiding deviation, and providing a stable movement reference for components such as pressing block 67 and top block 66 in storage cavity 65 of mounting bracket 64, thereby ensuring the positional accuracy when clamping and positioning is achieved through pressing block 67, restraining bolt 611, etc.

[0052] The slider 63 has a square hole on its surface. The pressing block 67 is slidably connected to the inner wall of the square hole and to the inner wall of the receiving cavity 65. The rubber gasket 68 abuts against the inner wall of the guide rail 62. Relying on the double-fit sliding connection between the pressing block 67 and the square hole of the slider 63 and the receiving cavity 65 of the second mounting bracket 64, when the pressing block 67 is pushed along the receiving cavity 65 by the restraining bolt 611, the rubber gasket 68 on the surface of the pressing block 67 can form a tight abutment with the guide rail 62 on the inner wall of the first mounting bracket 61. The rubber gasket 68 can effectively increase the static friction between the pressing block 67 and the guide rail 62. Thus, in the locked state, with the tightening force of the restraining bolt 611 and the limiting effect of the guide rail 62, the second mounting bracket 64 can be reliably locked, preventing it from shifting during the clamping and positioning process, and further ensuring the positioning stability of the assembly device 6.

[0053] The top block 66 has a storage groove on its side surface. The fixing plate 69 is located on the inner wall of the storage groove. The side of the return spring 610 away from the fixing plate 69 is fixedly connected to the inner wall of the storage groove. The top block 66 has a through hole on its upper surface. The binding bolt 611 is inserted into the inner wall of the through hole. The top block 66 has a chamfer on the inner wall of the through hole. When the binding bolt 611 is tightened, the binding bolt 611 can be smoothly inserted into the chamfered through hole on the upper surface of the top block 66 and push the top block 66 to move along the storage cavity 65, thereby compressing the return spring 610. In the locked state, the binding bolt 611 can counteract the rebound force of the return spring 610, and stably restrict the top block 66 to the state of "pushing the pressing block 67", so that the pressing block 67 is kept in close contact with the inner wall of the guide rail 62, and finally the pressing block 67 is reliably locked, further fixing the position of the mounting bracket 64 and ensuring the positioning accuracy of the assembly device 6.

[0054] Working principle of the invention: When producing and welding mining flat welded wire mesh, the steel wire 4 used for welding is placed on the clamping device 7 to clamp the steel wire 4 using the clamping structure. After all the horizontal and vertical steel wires 4 have been placed, the switch of the welding equipment installed on the side of the machine body can be turned on. The welding equipment is powered on and works to weld the intersections of the placed steel wires 4. After all the intersections have been welded, the steel wires 4 form a flat welded wire mesh. Then, the flat welded wire mesh can be removed from the clamping device 7 and subsequent processing operations can be carried out.

[0055] Before using the clamping device 7 to fix the steel wire 4, place the U-shaped frame 711 on the pre-reserved installation position of the mounting bracket 61 or the mounting bracket 64. After placing the U-shaped frame 711, push the knob 728. The knob 728, in conjunction with the connecting post 727, pushes the T-shaped locking pin 724. The T-shaped locking pin 724 is compressed by the force pressing the spring 726 and, guided by the protrusion 725 and the guide cavity, inserts into the slide groove. When the protrusion 725 is blocked by the guide cavity during movement, rotate the knob 728. The knob 728, in conjunction with the connecting post 727, rotates the T-shaped locking pin 724. The T-shaped locking pin 724 rotates the protrusion 725, and the protrusion 725, guided by the guide cavity, rotates the spring 726. The guide moves along the designated direction under the guidance of the cavity. When the protrusion 725 is blocked by the guide cavity again during the rotation, the knob 728 is released. The connecting post 727 loses the force applied to the T-shaped locking pin 724. The T-shaped locking pin 724 loses the pressure applied to the compression spring 726. The compression spring 726 loses the pressure and rebounds, pushing the T-shaped locking pin 724 and the protrusion 725 to reset. During the reset process, the protrusion 725 inserts into the recessed area reserved in the guide cavity, thereby locking the position of the T-shaped locking pin 724. When the position of the T-shaped locking pin 724 is locked, the U-shaped frame 711 can be initially restricted on the mounting bracket 1 61 or the mounting bracket 2 64.

[0056] After all U-shaped frames 711 are installed, move the U-shaped frames 711. Guided by mounting bracket 1 61 and mounting bracket 2 64, the U-shaped frames 711 move the acrylic plate 713 and the marking strip 714 along the specified direction. During the movement of the U-shaped frames 711, the user can control the spacing between the U-shaped frames 711 according to the position of the marking strip 714 and the scale on mounting bracket 1 61 or mounting bracket 2 64. When the spacing between the U-shaped frames 711 is adjusted to the designed distance, use a tool to rotate the locking bolt 712. After the locking bolt 712 is tightened, it can be used with mounting bracket 1 61 or mounting bracket 2 64 to lock the position of the U-shaped frames 711.

[0057] After completing the installation of the clamping device 7 according to the above steps, the wire 4 can be placed at the opening of the clamping frame 717. Then, push the wire 4 downwards directly above the opening. The arc surface of the wire 4 contacts the arc surface of the clamping frame 717. At this time, the clamping frame 717 rotates under the force applied by the wire 4 and compresses the limiting spring 718. The limiting spring 718 is compressed and deformed. During the rotation of the clamping frame 717, the opening of the clamping frame 717 widens. At this time, the wire 4 falls into the clamping area of ​​the clamping frame 717. After the wire 4 has completely fallen into the clamping area, the wire 4 loses the force applied to the clamping frame 717. The clamping frame 717 stops applying pressure to the limiting spring 718. The limiting spring 718 loses pressure and rebounds, pushing the clamping frame 717. After the holder 717 resets, it engages with the clamping plate 719 to clamp the wire 4, preventing it from shifting. Then, following the same procedure, all wires 4 are clamped and fixed for welding. When the specifications of the wire 4 to be processed change, the user can unscrew the fixing bolt 7110 to remove the clamping plate 719 and replace it with a clamping plate 719 of different thicknesses. The clamping device 7 allows for rapid adjustment within a specified range. Users can install or remove the clamping device 7 according to the specifications of the workpiece, thus adapting it to different workpiece specifications, effectively expanding its application scenarios and significantly improving its processing adaptability.

[0058] When the specifications of the steel wire 4 used for welding are different, and the position of the upper clamping device 7 of the mounting bracket 2 64 needs to be adjusted, the restraining bolt 611 is removed from the inner wall of the mounting bracket 2 64. When the restraining bolt 611 is removed from the mounting bracket 2 64, the top block 66 loses the restraint of the restraining bolt 611 and stops applying pressure to the return spring 610. The return spring 610 loses pressure and rebounds, and cooperates with the fixing plate 69 to push the top block 66 to reset. The reset top block 66 pulls the pressing block 67, and the pressing block 67 pulls the rubber pad 68. The rubber pad 68 is pulled away from the guide rail 62. After the unlocking of the structures on both sides of the mounting bracket 2 64 is completed, the mounting bracket 2 64 can be moved along the specified direction, thereby adjusting the position of the mounting bracket 2 64 in the vertical direction.

[0059] After adjusting the mounting bracket 64 to a position suitable for processing steel wire strip 4, insert the restraining bolt 611 into the receiving cavity 65 of the mounting bracket 64. Rotate the restraining bolt 611, and it will screw into the mounting bracket 64 and approach the top block 66. As the restraining bolt 611 is inserted into the through hole along the chamfer on the upper surface of the top block 66, it pushes the top block 66 in the specified direction. The top block 66 is forced to compress the return spring 610 and push the pressing block 67 and the rubber pad 68 to move. The rubber pad 68 moves to abut against the inner wall of the guide rail 62, and the top block 66 and the pressing block 67... Under the action of the slider 63, the position of the second mounting bracket 64 is locked. Then, the clamping device 7 installed on the second mounting bracket 64 can be adapted to the clamping structure on the first mounting bracket 61 to fit different specifications of steel wire strips 4. By setting the assembly device 6, the height of the clamping device 7 on the second mounting bracket 64 can be flexibly adjusted according to the needs of different specifications of steel wire strips 4, and it can be adapted to the clamping structure on the first mounting bracket 61. This effectively breaks the limitation of a single specification, improves the versatility of the clamping device 7, and further broadens its application range for different specifications of steel wire strips 4, ensuring processing adaptability.

[0060] In addition, after the front welding of the steel wire 4 is completed, the welding structure of the welding equipment leaves the welding area. Then, the cylinder 52 is controlled to lift the connecting frame 53. The connecting frame 53, together with the positioning frame 54, pushes the servo motor 55, coupling 56, rotating shaft 57 and assembly frame 58. As the assembly frame 58 moves upward, it lifts the assembly device 6 and clamping device 7. The clamping device 7 pushes the steel wire 4 upward. When the clamping device 7 moves to its maximum height, the servo motor 55 works with the coupling 56 to drive the rotating shaft 57 at low speed. The rotating shaft 57 rotates the assembly frame 58, and the assembly frame 58 rotates the assembly device 6. After the assembly device 6 rotates 180°, the assembly device 6, together with the clamping device 7, reverses the steel wire 4. After the steel wire 4 has reversed, the cylinder 52 resets, so as to move the assembly device 6, clamping device 7 and steel wire 4 back to their original positions with the connecting frame 53 and other structures. When the steel wire 4 is reset, the welding equipment starts working again to weld the back of the steel wire 4.

[0061] After the welding on the back side is completed, the welding equipment is removed from the welding area, the cylinder 52 works again, and according to the above steps, the welded steel wire 4 is rotated back to face up. After the steel wire 4 is reset, the flat welded mesh composed of steel wire 4 can be removed from the clamping device 7. By setting the adjustment device 5 to controllably adjust the orientation of the steel wire 4, it is ensured that the intersection of the steel wire 4 can form a double welding node on the front and back sides, which effectively improves the welding firmness and overall structural strength of the intersection of the steel wire 4, and further optimizes the continuity and convenience of the welding operation.
