Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a switchgear gas chamber welding displacement device. Background Technology

[0002] Switchgear welding is a crucial step in the manufacturing process of electrical equipment. By welding metal components together, the reliability and structural stability of the electrical equipment connected within the switchgear are ensured. The welding quality directly affects the safe operation, durability, and overall performance of the switchgear. Welding is categorized into three main types: pressure welding, fusion welding, and special welding. Pressure welding only requires applying pressure to the connection points to join two workpieces together; examples include cold welding and hot press welding. Fusion welding utilizes high temperatures to melt the surface of the workpieces into a liquid, and the molten metal forms a bond after cooling; examples include electric arc welding and TIG welding. Special welding methods are based on specific phenomena and physical properties, such as laser welding and plasma welding.

[0003] During the welding of switchgear gas chambers, different welding heads need to be changed for different welding processes. The existing approach is to transport the switchgear and set up different welding platforms to perform different types of welding on the switchgear, resulting in poor overall welding efficiency. Furthermore, since the welding machine needs to perform repositioning welding inside the switchgear gas chamber, the entire welding machine base occupies a large area due to the use of a robotic arm or a dual-axis linear motor platform for repositioning welding heads. When using a combination of three welding machine bases to weld the switchgear gas chamber, the problem of interference between the movements of each welding head needs to be considered. In view of this, we propose a switchgear gas chamber welding repositioning device. Summary of the Invention

[0007] Preferably, the screw seat is slidably connected to the inner wall of the limiting top seat, and the output shaft of the dual-axis linear motor is fixedly connected to the welding head.

[0008] Preferably, the welding device further includes a cam holder, which is slidably connected to the connecting frame rod. A sleeve is rotatably connected inside the cam holder, and a meshing gear is fixedly connected to the sleeve. A slidable shaft is slidably connected inside the sleeve.

[0009] Preferably, a spring is fixedly connected between the surface of the cam holder and the surface of the limiting top seat, and the end of the cam shaft passes through one side of the limiting top seat and is fixedly connected to the end of the bidirectional threaded rod.

[0010] Preferably, a cam push rod is fixedly connected to the welding positioner base, and the cam push rod is used to press the cam holder to achieve displacement.

[0011] Preferably, the fixed control telescopic device includes a control motor, which is installed inside the welding positioner base. The output shaft of the control motor is fixedly connected to a drive gear, and a transmission gear ring meshes with the surface of the drive gear. A fixed ring seat is rotatably connected to one side of the transmission gear ring, and a guide ring seat is fixedly connected to the inner ring wall of the transmission gear ring. The fixed ring seat is fixedly connected inside the welding positioner base.

[0012] Preferably, the hydraulic clamping device includes a hydraulic base, which is fixed inside the welding positioner base. A slide rod is slidably connected to the top of the hydraulic base. A slide shaft is fixedly connected to one end of the slide rod, and a hydraulic plate is fixedly connected to the other end of the slide rod. Flow pipes are fixedly connected to both sides of the hydraulic base. A hydraulic pipe is fixedly connected to the end of the flow pipe. A piston rod is connected inside the hydraulic pipe, and a clamping plate is fixedly connected to the end of the piston rod.

[0013] Preferably, the hydraulic plate piston is connected inside the hydraulic base, a spring is fixedly connected between the surface of the sliding shaft and the surface of the hydraulic base, the end of the sliding shaft is slidably connected to the inner wall of the guide ring seat, and the interior of the hydraulic base is connected to the interior of the hydraulic pipe through a flow pipe.

[0014] As can be seen from the above technical solutions, the switchgear gas chamber welding displacement device provided in the embodiments of this specification has at least the following beneficial effects:

[0015] 1. This invention achieves three different welding methods for welding the switchgear gas chamber by setting up three different welding heads. These heads are centrally positioned in a fan-shaped array on the top area of ​​the welding positioner base, reducing the footprint. A positioner motor drives a worm gear transmission worm wheel ring to move the three welding devices, thus achieving automatic positioning and welding of the three welding heads. A fixed-control telescopic device regulates the welding devices vertically positioned at the top of the positioning platform, controlling the welding heads on these devices to move towards the switchgear, aligning the corresponding welding heads with the switchgear gas chamber for welding. The remaining two welding devices control their respective welding heads to retract at the top of the welding positioner base, achieving the effect of not interfering with the welding heads during the welding process. This achieves multi-station automatic positioning and welding of the switchgear, reducing the operating time during traditional switchgear welding and improving welding efficiency.

[0016] 2. This invention uses a bidirectional threaded rod to drive two symmetrical threaded seats to move closer together, and a telescopic connecting rod to extend. The telescopic connecting rod transmits force to the connecting seat on the limiting rod through a sliding block. The connecting seat drives the welding head to move towards the switch cabinet through a dual-axis linear motor, achieving an automatic alignment effect. The welding head corresponding to the welding requirements moves a long distance to align with the welding. Combined with the method of retracting the remaining two welding heads on the top of the welding positioner base, the area occupied by the three welding heads is reduced while achieving the effect of not interfering with the welding head during the welding process.

[0017] 3. This invention uses a cam push rod to compress and displace the cam holder, so that the meshing gear on the cam holder at that location is aligned with the transmission gear ring to maintain the transmission effect. At the same time, since the cam holders at the other two locations are in a state far away from the limit push seat, the corresponding meshing gears on them are misaligned with the transmission gear ring. This achieves the effect of not working on the two welding heads, and also ensures that when the three welding heads are rotated and displaced, the corresponding telescopic connecting rods do not perform ineffective movement.

[0018] 4. This invention controls a motor to drive a drive gear to mesh with a transmission gear ring. In the initial stage of rotation, the transmission gear ring squeezes the sliding shaft rod through the combined groove in the guide ring seat. The sliding shaft rod is forced to compress the spring on its surface, and through the sliding rod, it drives the hydraulic plate to squeeze the liquid in the hydraulic base. After being squeezed, the liquid flows evenly out to the flow pipes on both sides. The flow pipes move through the hydraulic drive hydraulic pipe clamps. During the movement of the two symmetrical clamps close to each other, the switch cabinet on the positioning platform is clamped and positioned. The power of the control welding head to align with the switch cabinet for close welding drives the two clamps to clamp the switch cabinet, achieving the effect of automatic clamping and positioning. At the same time, the use of power can reduce the setting of drive components, thereby reducing equipment costs to a certain extent. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 - Figure 10As shown, a switchgear gas chamber welding positioning device includes a welding positioning machine base 1. A positioning motor 2 is fixedly installed on one side of the welding positioning machine base 1. A worm gear 3 is fixedly connected to the output shaft of the positioning motor 2. A worm wheel ring 4 meshes with the surface of the worm gear 3. Three sets of welding devices 5 are distributed in a fan-shaped array on the worm wheel ring 4. The three sets of welding devices 5 have the same internal structure, and three different welding heads 6 are provided on the three sets of welding devices 5. The three different welding heads 6 are used to perform three different welding operations on the switchgear gas chamber, and are distributed in a fan-shaped array. The welding positioner base 1 is centrally located at the top, reducing its footprint. A positioning motor 2 drives a worm gear 3, which in turn drives a worm wheel ring 4 to move three welding devices 5, thus achieving automatic positioning and welding of the three welding heads 6. A hydraulic clamping device 7, mounted on the welding positioner base 1, is used to position and clamp the switchgear on both sides during welding, improving welding stability. A fixed-control telescopic device 8, also mounted on the welding positioner base 1, drives the welding devices 5 and controls the welding machine. The head 6 is telescopic; the positioning platform 9 is set on the welding positioner base 1, and the positioning platform 9 is movably connected to the positioning platform 9. The switch cabinet to be welded is placed flat on the positioning platform 9. The auxiliary rollers 10 facilitate the adjustment of the position of the switch cabinet on the positioning platform 9. The air chamber cavity to be welded of the switch cabinet is placed facing upwards. The fixed control telescopic device 8 controls the welding device 5 at the top vertical of the positioning platform 9, and controls the welding head 6 on the welding device 5 to move towards the switch cabinet, so that the corresponding welding head 6 aligns and welds the air chamber of the switch cabinet. The remaining two sets of welding devices 5 control the corresponding welding heads 6 to retract to the top of the welding positioner base 1, so as to achieve the effect of not interfering with the welding head 6 in the welding work, thereby achieving the effect of multi-station automatic position welding of the switch cabinet, reducing the running time during traditional switch cabinet welding, and improving welding efficiency. The worm gear ring 4 is set as a hollow ring, and the end of the worm gear ring 4 is rotatably connected to the welding positioner base 1. The connection between the worm gear ring 4 and the worm 3 ensures the transmission effect while achieving self-locking, improving the overall stability of the welding head 6.

[0033] In this embodiment, the welding device 5 includes a connecting rod 51, which is fixedly connected to the worm gear ring 4. A limiting top seat 52 is fixedly connected to the surface of the connecting rod 51. A bidirectional threaded rod 53 is rotatably connected inside the limiting top seat 52. Two symmetrical screw seats 54 are threadedly connected to the bidirectional threaded rod 53, and the screw seats 54 are slidably connected to the inner wall of the limiting top seat 52. When the bidirectional threaded rod 53 rotates, the two screw seats 54 move relative to each other, that is, they move closer to each other or move further away from each other. A telescopic connecting rod 55 is rotatably connected to the screw seats 54. 5 is composed of multiple cross links and shafts. The two ends of the first cross link in the telescopic link 55 are rotatably connected to the inside of the screw seat 54 through the shaft. The two ends of the last cross link in the telescopic link 55 are slidably connected to the limit rod 57 through two symmetrical slide seats 56. The limit rod 57 is fixedly connected to the connecting seat 58, and the connecting seat 58 is fixedly connected to the dual-axis linear motor 59. The output shaft of the dual-axis linear motor 59 is fixedly connected to the welding head 6. The dual-axis linear motor 59 is composed of two linear motors vertically combined and is used to drive the welding head 6 to move along the x-axis and y-axis. When the bidirectional threaded rod 53 rotates and drives the two symmetrical threaded seats 54 to move closer together, the telescopic connecting rod 55 extends. The telescopic connecting rod 55 transmits force to the connecting seat 58 on the limit rod 57 through the slide 56. The connecting seat 58 drives the welding head 6 to move towards the switch cabinet through the dual-axis linear motor 59, achieving the effect of automatic alignment. The welding head 6 corresponding to the welding requirements is moved a long distance to be aligned for welding. Combined with the way that the remaining two welding heads 6 are retracted on the top of the welding positioner base 1, the area occupied by the three welding heads 6 is reduced, while achieving the effect of not interfering with the welding head 6 during the welding process.

[0034] Furthermore, the welding device 5 also includes a cam holder 510, which is slidably connected to the connecting frame rod 51 via grooves on both sides. A sleeve 511 is rotatably connected inside the cam holder 510, and a meshing gear 512 is fixedly connected to the surface of the sleeve 511. A retaining shaft 513 is slidably connected inside the sleeve 511. A spring is fixedly connected between the surface of the cam holder 510 and the surface of the limiting top seat 52. The end of the retaining shaft 513 passes through one side of the limiting top seat 52 and is fixedly connected to the end of the bidirectional threaded rod 53. The spring is used to limit the position of the cam holder 510. The cam holder 510 located directly above the positioning platform 9 is in a ready-to-work state, with the spring at this cam holder 510 in a contracted state, and the cam holder 510 is close to the limiting top seat 52. The other two cam holders 510 are in a non-working state, away from the limiting top seat 52.

[0035] Furthermore, a cam push rod 514 (such as...) is fixedly connected to the welding positioner base 1. Figure 10As shown, the cam push rod 514 is used to press the cam holder 510 to achieve displacement. When the displacement motor 2 drives the worm gear 3 to drive the worm wheel ring 4 to drive the three sets of welding devices 5 to perform displacement, the cam holder 510 at the corresponding position rotates synchronously with the connecting frame rod 51 at the corresponding position. During the rotation, when it gradually contacts the cam push rod 514, the cam holder 510 contacts and presses the cam push rod 514 at the top through the convex arc surface at the top. The cam holder 510 as a whole performs a passive displacement movement, thereby realizing that the cam holder 510 at the cam push rod 514 is close to the limit top seat 52, realizing the effect of switching between non-working state and waiting-to-work state.

[0036] In addition, the fixed-control telescopic device 8 includes a control motor 81, which is installed inside the welding positioner base 1. The output shaft of the control motor 81 is fixedly connected to a drive gear 82. A transmission gear ring 83 meshes with the surface of the drive gear 82. A fixed ring seat 84 is rotatably connected to one side of the transmission gear ring 83. A guide ring seat 85 is fixedly connected to the inner ring wall of the transmission gear ring 83. The fixed ring seat 84 is fixedly connected inside the welding positioner base 1. When the cam holder 510 at the cam push rod 514 approaches the limit top seat 52, the meshing gear 512 on the cam holder 510 and the transmission gear ring 83 are at the same horizontal plane. At this time, by starting the control motor 81, the output shaft of the control motor 81 rotates through the drive gear 82 meshing with the transmission gear ring 83, and the transmission gear ring 83... During rotation, the meshing gear 512 at the cam push rod 514 rotates. The meshing gear 512 transmits the rotational force to the bidirectional threaded rod 53 through the sleeve 511 and the shaft 513, thereby controlling the telescopic connecting rod 55 at that location to push out the welding head 6. This achieves the effect of automatically aligning the welding head 6 with the switch cabinet air chamber for close welding. Meanwhile, since the cam holders 510 at the other two locations are in a state far away from the limit top seat 52, the corresponding meshing gears 512 and the transmission gear ring 83 on them are misaligned. Therefore, the other two welding heads 6 do not work. This achieves the effect of not working the two welding heads 6, and also ensures that when the three welding heads 6 rotate and change position, the corresponding telescopic connecting rods 55 do not perform ineffective movement.

[0037] In addition, the hydraulic clamping device 7 includes a hydraulic base 71, which is fixed inside the welding positioner base 1. The interior of the hydraulic base 71 is filled with liquid. A slide rod 72 is slidably connected to the top of the hydraulic base 71. A slide shaft 73 is fixedly connected to one end of the slide rod 72. A spring is fixedly connected between the surface of the slide shaft 73 and the surface of the hydraulic base 71. A hydraulic plate 74 is fixedly connected to the other end of the slide rod 72. The hydraulic plate 74 is piston-connected inside the hydraulic base 71. The end of the slide shaft 73 is slidably connected to the inner wall of the guide ring seat 85. When the output shaft of the control motor 81 transmits the rotation of the gear ring 83 through the meshing of the drive gear 82 (the rotation of the gear ring 83 does not exceed one revolution), a combined groove is opened inside the guide ring seat 85. This combined groove is composed of a circular arc groove and a triangular protrusion groove (e.g., Figure 7 As shown), in the initial state, the sliding shaft 73 is located in the triangular convex groove. When the guide ring seat 85 rotates, it will squeeze the sliding shaft 73 downward through the inner wall of the triangular convex groove. In the initial stage of rotation, the transmission gear ring 83 squeezes the sliding shaft 73 through the combined groove in the guide ring seat 85. The sliding shaft 73 is compressed by the force of the spring on its surface, and through the sliding rod 72, it drives the hydraulic plate 74 to squeeze the liquid in the hydraulic base 71. The rotation angle of the transmission gear ring 83 is less than the angle of the arc groove distribution. After rotating in the forward direction, it can be reset and reversed by controlling the motor 81. Both sides of the hydraulic base 71 are fixedly connected to the flow pipe 75. The end of the flow pipe 75 is fixedly connected to the hydraulic pipe 76. The piston inside the hydraulic pipe 76 is connected to the stop rod 77. A clamping plate 78 is fixedly connected to the end of the 7. The interior of the hydraulic base 71 is connected to the interior of the hydraulic pipe 76 through the flow pipe 75. After being squeezed by force, the liquid flows out evenly to the flow pipes 75 on both sides. The flow pipe 75 moves the clamping plate 78 on the hydraulic pipe 76 through the hydraulic drive. During the movement of the two symmetrical clamping plates 78 close to each other, the switch cabinet on the positioning platform 9 is clamped and positioned. The power of the welding head 6 is used to drive the two clamping plates 78 to clamp the switch cabinet, achieving the effect of automatic clamping and positioning. At the same time, the use of power can reduce the setting of driving components, thereby reducing equipment costs to a certain extent, and further achieving the effect of stable clamping of the switch cabinet during the welding work.

[0038] In use, the switchgear gas chamber welding positioning device of the present invention places the switchgear to be welded on the positioning platform 9, selects the corresponding welding head 6 according to the welding requirements, and starts the positioning motor 2. The positioning motor 2 drives the worm gear 3 to drive the three welding devices 5 on the worm wheel ring 4 to reposition. The corresponding welding device 5 is positioned directly above the positioning platform 9. During the rotation of the worm wheel ring 4, the cam holder 510 at the corresponding position rotates synchronously with the connecting rod 51 at the corresponding position. When it gradually contacts the cam push rod 514 during the rotation, the cam holder 510 contacts and presses against the convex arc surface at the top of the cam push rod 514 through the convex arc surface at the top of the cam holder 510. The entire assembly undergoes a passive yielding motion, causing the cam holder 510 at the cam push rod 514 to approach the limit top seat 52, achieving the effect of switching between a non-working state and a standby state. At this time, the meshing gear 512 on the cam holder 510 and the transmission gear ring 83 are on the same horizontal plane. By starting the control motor 81, the output shaft of the control motor 81 drives the transmission gear ring 83 to rotate via the drive gear 82. During rotation, the transmission gear ring 83 drives the meshing gear 512 at the cam push rod 514 to rotate. This meshing gear 512 transmits the rotational force to the bidirectional threaded rod 53 via the sleeve 511 and the clasp 513. The rotation of the bidirectional threaded rod 53 drives the two symmetrical threaded seats 54 to rotate. As the device approaches, the telescopic link 55 extends, transmitting force to the connecting seat 58 on the limit rod 57 via the slide 56. The connecting seat 58 then drives the welding head 6 towards the switch cabinet via the dual-axis linear motor 59, achieving automatic alignment. This allows the welding head 6 to be moved a long distance to align with the welding requirements. Combined with the retraction of the remaining two welding heads 6 on top of the welding positioner base 1, this reduces the area occupied by the three welding heads 6 while ensuring that the welding heads 6 do not interfere with the welding process. When the output shaft of the control motor 81 meshes with the drive gear 82 to transmit the rotation of the gear ring 83, the gear ring 83 initially rotates through the combined groove in the guide ring seat 85. The sliding shaft 73 is pressed, and the spring on its surface is compressed. The sliding shaft 73, through the sliding rod 72, drives the hydraulic plate 74 to compress the liquid in the hydraulic base 71. After being compressed, the liquid flows evenly out to the flow pipes 75 on both sides. The flow pipes 75 are moved by the hydraulic drive hydraulic pipe 76. During the movement of the two symmetrical clamps 78 towards each other, the switch cabinet on the positioning platform 9 is clamped and positioned. The power of the control welding head 6 to align with the switch cabinet for close welding drives the two clamps 78 to clamp the switch cabinet, achieving the effect of automatic clamping and positioning. At the same time, the use of power can reduce the setting of drive components, thereby reducing equipment costs to a certain extent.
