[0030] In one embodiment of the present invention, see Figure 1-Figure 2 The column clamping assembly 3 includes a plurality of support cross bars 301 arranged on the side close to each other of the support turntable 2, and the end of the support cross bar 301 away from the support turntable 2 is connected through an end plate 302, and a plurality of support cross bars 301 are respectively slidably provided with a first movable clamping plate 304 and a second movable clamping plate 305 that cooperate with each other, and a first spring 303 sleeved on the outside of the support cross bar 301 is connected between the end plate 302 and the first movable clamping plate 304, and an electric cylinder 306 connected to the second movable clamping plate 305 is installed on the support turntable 2.

[0031] In this embodiment, in the initial state, the second movable splint 305 is close to the supporting turntable 2, the first movable splint 304 is in contact with the second movable splint 305, and the first spring 303 is at its original length. When it is necessary to clamp the upright post of the fence 9, the first movable splint 304 is pushed away from the supporting turntable 2, the first spring 303 is stressed and contracts, the upright post is horizontally placed on a plurality of supporting cross bars 301 and is located between the first movable splint 304 and the second movable splint 305, the first movable splint 304 is released, the first spring 303 extends and pushes the first movable splint 304 close to the supporting turntable 2, the first movable splint 304 clamps the upright post by cooperating with the second movable splint 305, according to the actual spacing requirement between the two upright posts, the electric cylinder 306 extends toward the middle of the U-shaped bracket 1 and pushes the second movable splint 305 away from the supporting turntable 2, the spacing between the two second movable splints 305 can be adjusted, and the welding requirements of upright posts with different spacings can be met; Among them, several supporting cross bars 301 are horizontally arranged on the supporting turntable 2, which can provide stable support for the column. The supporting cross bars 301 are at least provided with 3, and the first movable clamp plate 304 is set as an L-shaped clamp plate and the protruding end is located at the end of the first movable clamp plate 304 away from the supporting cross bar 301. Through the cooperation of the first movable clamp plate 304 and the second movable clamp plate 305, the left and right sides of the column can be clamped, and through the cooperation of the supporting cross bar 301 and the protruding end of the first movable clamp plate 304, the upper and lower sides of the column can be clamped, thereby improving the stability of the clamping of the column and preventing the column from slipping after flipping.

[0032] In one embodiment of the present invention, see Figure 1-Figure 4 The vertical rod clamping assembly 4 includes a supporting rotating rod 401 fixedly connected between the two supporting rotating disks 2, and the two ends of the supporting rotating rod 401 are symmetrically provided with sliding grooves 402, and the middle part of the sliding groove 402 is fixedly provided with a fixed seat 403, and the supporting rotating rod 401 is movably sleeved with a plurality of sliding seats 404 symmetrically distributed about the fixed seat 403, and the sliding seat 404 is slidably matched with the sliding groove 402, and the fixed seat 403 and the plurality of sliding seats 404 are fixedly installed with a connecting frame 405, and movable slide plates 406 are respectively slidably provided at both ends of the connecting frame 405, and the ends of the movable slide plates 406 that are away from each other are connected to the corresponding first pneumatic clamping jaws 5, and a spacing adjustment module is provided between the connecting frame 405 and the supporting rotating disk 2; The spacing adjustment module includes a support 407 fixedly arranged at the bottom of the fixed seat 403 and a threaded seat 409 fixedly arranged at the bottom of the sliding seat 404 away from the fixed seat 403. A screw 408 is rotatably connected between the support 407 and the supporting turntable 2. The screw 408 is threadedly connected to the threaded seat 409. The screw 408 is connected to a first adjustment motor 410 installed on the supporting turntable 2. The connecting frame 405 is symmetrically provided with guide grooves 411 on one side close to the supporting rotating rod 401. The two guide grooves 411 are respectively provided with sliding There are a first connecting column 412 and a second connecting column 413 connected to the corresponding movable slide plate 406, the first connecting column 412 on the connecting frame 405 is movably connected to the second connecting column 413 on the adjacent connecting frame 405 via a first hinge plate 414, the second connecting column 413 on the connecting frame 405 is movably connected to the first connecting column 412 on the adjacent connecting frame 405 via a second hinge plate 415, and the first hinge plate 414 and the second hinge plate 415 located between the two connecting frames 405 are rotatably connected via a pin shaft 416.

[0033] In this embodiment, in the initial state, the spacing between adjacent connection frames 405 is at a suitable position, and a plurality of vertical rods are placed on the connection frames 405 in sequence. The first pneumatic clamps 5 located at both ends of the connection frames 405 can clamp both ends of the vertical rods to facilitate subsequent welding processing; When the length of the vertical rod in the fence 9 is long, the increase in the length of the vertical rod will reduce its bending stiffness, and it is easy to bend under wind pressure or external force. It is necessary to disperse the load by reducing the welding spacing to improve the overall lateral force resistance. Therefore, it is necessary to reduce the spacing between two adjacent connecting frames 405. Specifically, the first adjusting motor 410 drives the screw 408 to rotate clockwise, and the screw 408 drives the sliding seat 404 located on the outside to approach the fixed seat 403 by threaded connection with the threaded seat 409 and the sliding cooperation between the sliding seat 404 and the sliding groove 402. The sliding seat 404 drives the movable slides 406 at both ends to move synchronously. Through the rotation cooperation of the cross-arranged first hinge plate 414 and the second hinge plate 415 and the sliding cooperation between the first connecting column 412 and the second connecting column 413 and the guide groove 411, it is possible to achieve the contraction of several connecting frames 405 toward the fixed seat 403 and Moreover, during the movement of the connection frame 405, the distance between two adjacent connection frames 405 is always kept consistent. At the same time, as the distance between two adjacent connection frames 405 decreases, the angle between the first hinge plate 414 and the second hinge plate 415 corresponding to the same connection frame 405 becomes larger, and the outer ends of the first hinge plate 414 and the second hinge plate 415 push the corresponding movable slide plate 406 toward the outer end of the connection frame 405 through the first connection column 412 and the second connection column 413 respectively, and the movable slide plate 406 drives the first pneumatic clamping jaw 5 to move synchronously, so that the two first pneumatic clamping jaws 5 symmetrically distributed about the connection frame 405 are separated from each other; when the movable slide plate 406 is extended outward to a suitable position, the first adjustment motor 410 stops working, and the two ends of a plurality of long vertical rods can be clamped by a plurality of symmetrically distributed first pneumatic clamping jaws 5, thereby improving the applicability of the device; When the length of the vertical rod in the fence 9 is short, the welding spacing can be increased due to the strong bending resistance of the short vertical rod. Therefore, the spacing between two adjacent connecting frames 405 can be increased. Specifically, the first adjusting motor 410 drives the screw 408 to rotate counterclockwise, and the screw 408 drives the sliding seat 404 located on the outside to move away from the fixed seat 403 by means of threaded connection with the threaded seat 409 and sliding cooperation between the sliding seat 404 and the sliding groove 402. The sliding seat 404 drives the movable slides 406 at both ends to move synchronously, and the several connecting frames 405 are moved away from the fixed seat 403 by means of the rotation cooperation of the cross-arranged first hinge plate 414 and the second hinge plate 415 and the sliding cooperation of the first connecting column 412 and the second connecting column 413 and the guide groove 411. In addition, during the movement of the connecting frame 405 , the spacing between two adjacent connection frames 405 is always kept consistent. At the same time, as the spacing between two adjacent connection frames 405 increases, the angle between the first hinge plate 414 and the second hinge plate 415 corresponding to the same connection frame 405 becomes smaller, and the outer ends of the first hinge plate 414 and the second hinge plate 415 push the corresponding movable slide plate 406 to move inside the connection frame 405 through the first connection column 412 and the second connection column 413 respectively, and the movable slide plate 406 drives the first pneumatic clamping jaw 5 to move synchronously, so that the two first pneumatic clamping jaws 5 symmetrically distributed about the connection frame 405 are close to each other; when the movable slide plate 406 is retracted to a suitable position, the first adjustment motor 410 stops working, and the two ends of a plurality of short vertical rods can be clamped by a plurality of symmetrically distributed first pneumatic clamping jaws 5; Among them, the length of the first connecting column 412 is consistent with the length of the second connecting column 413, and the connecting line of several pin shafts 416 is in the same vertical plane with the axis of the supporting rotating rod 401, which can ensure that the movable slides 406 at both ends of the connecting frame 405 are synchronously extended and contracted. At the same time, by moving the first pneumatic clamp 5, the clamping position between the first pneumatic clamp 5 and the vertical rod can be adjusted, and it can be ensured that there is a certain distance between the clamping position between the first pneumatic clamp 5 and the vertical rod and the end of the vertical rod, which can leave enough operating space for the welding position between the vertical rod and the crossbeam. In addition, by adjusting the clamping position, the clamping stability of the vertical rod can be enhanced, avoiding the clamping positions at both ends of the vertical rod being too close to the middle of the vertical rod and unable to stably support the end of the vertical rod, thereby solving the problem that the end of the vertical rod is prone to shaking during welding.

[0034] In one embodiment of the present invention, see Figure 1-Figure 6The crossbeam clamping assembly 6 includes two sets of side ears 601 symmetrically arranged on one end of the movable slide 406 close to the first pneumatic clamp 5, and a movable frame 603 is movably arranged between two adjacent movable slides 406. The two side walls of the movable frame 603 are rotatably connected to the side ears 601 on the movable slide 406 on the corresponding side through a third hinge plate 602. A sliding support rod 604 is penetrated and slidably arranged on the movable frame 603. The end of the sliding support rod 604 close to the supporting rotating rod 401 is connected to a retaining ring 605 The other end of the sliding support rod 604 is connected to the second pneumatic clamp 7, and a plurality of limiting holes 606 are distributed on the sliding support rod 604. A connecting groove 607 is provided on the upper surface of the movable frame 603. A shift plate 608 corresponding to the connecting groove 607 is rotatably provided on the movable frame 603. A limiting pin 609 that passes through the connecting groove 607 and is movably connected to the limiting hole 606 is provided at one end of the shift plate 608. A second spring 610 is connected between the other end of the shift plate 608 and the upper surface of the movable frame 603.

[0035] In this embodiment, in the initial state, the angle between the third hinged plates 602 on both sides of the movable frame 603 is an obtuse angle. At this time, the spacing between two adjacent movable slides 406 is at a suitable distance, and the limiting pin 609 is connected to the limiting hole 606. Through the first pneumatic clamp 5, a vertical rod of a suitable length can be clamped, and the position of the corresponding second pneumatic clamp 7 is adjusted according to the shape of the crossbeam. Specifically, the end of the dial plate 608 close to the second spring 610 is pressed downward, and the second spring 610 is stressed and contracts. The dial plate 608 drives the limiting pin 609 to rotate upward, and the connection between the limiting pin 609 and the limiting hole 606 is released. The position of the second pneumatic clamp 7 is adjusted by pulling the sliding support rod 604 outward or pushing the sliding support rod 604 inward, so that the second pneumatic clamp 7 can clamp the corresponding position of the beam, and then release the paddle plate 608, the second spring 610 extends upward and pushes the paddle plate 608 to rotate upward near the end of the second spring 610, and the paddle plate 608 drives the limiting pin 609 to rotate downward, so that the limiting pin 609 is connected with the corresponding limiting hole 606, so that the position of the sliding support rod 604 is fixed, thereby fixing the position of the second pneumatic clamp 7, and adaptively clamping beams of different shapes can be processed, thereby improving the applicability of the device; At the same time, according to the different lengths of the vertical rods, the spacing between the two adjacent movable slides 406 will be adjusted accordingly. When the long vertical rod is clamped, the spacing between the two adjacent movable slides 406 is reduced, and the angle between the third hinged plates 602 on both sides of the movable frame 603 is reduced, so that the movable frame 603 is away from the supporting rotating rod 401, and the synchronous outward movement of the sliding support rod 604 and the second pneumatic clamp 7 can be achieved; when the short vertical rod is clamped, the spacing between the two adjacent movable slides 406 is increased, and the angle between the third hinged plates 602 on both sides of the movable frame 603 is increased, so that the movable frame 603 is close to the supporting rotating rod 401, and the synchronous inward movement of the sliding support rod 604 and the second pneumatic clamp 7 can be achieved; through the adaptive movement of the second pneumatic clamp 7, the spacing between the first pneumatic clamp 5 and the second pneumatic clamp 7 can be adjusted to meet the abutment requirements of different positions of the vertical rod and the crossbeam; In addition, by the third hinged plate 602 rotatably connected on both sides of the movable frame 603, it can be ensured that the movable frame 603 is always located in the middle of the two adjacent movable slides 406, so that the second pneumatic clamp 7 can be located in the middle of the welding point between the adjacent vertical rods and the horizontal beams, and sufficient operating space can be left for the welding between the vertical rods and the horizontal beams, thereby avoiding the second pneumatic clamp 7 being too close to the welding point and unable to perform comprehensive welding processing on the welding point.

[0036] In one embodiment of the present invention, see Figure 1-Figure 7 The angle adjustment assembly 8 includes a worm gear ring 801 arranged on a side wall of the support turntable 2 away from the vertical rod clamping assembly 4, and a worm 802 meshing with the worm gear ring 801 is rotatably provided on the side wall of the U-shaped bracket 1, and the worm 802 is connected to a second adjustment motor 803 installed on the U-shaped bracket 1.

[0037] In this embodiment, in the initial state, the connecting frame 405 is in a horizontal state and is located above the supporting rotating rod 401. In this state, the clamping and welding processing of the columns, beams and several vertical rods can be realized; after the welding of the upper surface of the fence 9 is completed, the second adjusting motor 803 drives the worm 802 to rotate, and the worm 802 drives the supporting rotating rod 401 to rotate synchronously by engaging with the second adjusting motor 803 and the supporting turntable 2 and the U-shaped bracket 1, so that the supporting rotating rod 401 rotates 180°. At this time, the connecting frame 405 is in a horizontal state and the connecting frame 405 is located below the supporting rotating rod 401. In this state, the lower surface of the fence 9 is flipped to the top, which is convenient for the staff to perform welding processing on it, avoiding the inefficiency of manually flipping the fence 9 and reducing the workload of the staff.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
