Technical Field

[0001] This utility model relates to the field of auxiliary devices for power equipment installation, and more specifically, to a combined busbar welding bracket. Background Technology

[0002] In the welding operation of busbar pipe joints, the welding end of the busbar pipe is usually inserted into the three-jaw chuck of the welding equipment for fixed welding.

[0003] However, in actual production, different specifications of busbars need to be processed, and the diameter and centerline position of the busbars will change. Traditional welding brackets are difficult to adapt to the stable support and precise positioning of busbars of different specifications, which leads to problems such as busbar displacement and shaking during welding. This not only affects the welding quality but also reduces welding efficiency, increases production costs and the workload of manual adjustment. In view of this, we propose a combined busbar welding bracket. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a combined busbar welding bracket to solve the technical problem that the current welding bracket is difficult to adapt to the stable support and precise positioning of busbars of different specifications, which leads to the busbars being prone to displacement and shaking during welding.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a combined busbar welding bracket, including a base, two telescopic rods fixedly installed on the top of the base, an adjusting component fixedly installed at the middle of the top of the base, a horizontal plate fixedly connected to the top of the two telescopic rods, a cylinder fixedly installed on the top of the horizontal plate, and a clamp for clamping the busbar fixedly installed on the top of the cylinder.

[0006] The clamp includes a support block, the top of which has two parallel movable slots. A limiting plate is fixedly installed in the middle of each movable slot. A gripper is slidably installed between the two movable slots. Inside each movable slot, two positioning plates that cooperate with the gripper for limiting are movably installed.

[0007] This invention utilizes a cylinder to provide a stable power source for the clamp, enabling it to quickly and stably grip the busbar pipe. The unique internal structure of the clamp allows the grippers to slide flexibly within the movable groove, achieving precise positioning through cooperation with the positioning plate. This allows for adaptive adjustment and secure clamping according to the busbar pipe's diameter, ensuring stability during welding and preventing welding quality issues caused by shaking or displacement, thus improving welding precision and quality.

[0008] Preferably, an extrusion member is installed through the wall of the limiting plate, and two adjusting blocks that fit against the sides of the extrusion member are movably installed at the bottom of the inner cavity of the movable groove. The bottom side of the adjusting block fits against the end of the positioning plate, and the contact surfaces of the adjusting block and the positioning plate are both upwardly inclined slopes. A first spring supporting the extrusion member is fixedly installed at the center of the bottom of the inner cavity of the movable groove.

[0009] Preferably, the gripper includes a pressing block, the bottom of which is movably mounted with a movable block that fits against the side of the movable groove, and the bottom of the movable block is fixedly provided with a positioning element that cooperates with the positioning plate.

[0010] Preferably, the top of the positioning plate has several positioning slots that are adapted to and inserted into the positioning component, and the side of the positioning plate that fits with the movable slot has several ball bearings embedded in it to reduce the resistance to movement.

[0011] Preferably, the extrusion member includes a fixing rod, and a triangular pressure block that cooperates with the adjusting block is fixedly provided at the bottom of the fixing rod, and the contact surfaces of the triangular pressure block and the adjusting block are both downward inclined surfaces.

[0012] Preferably, a slider is fixedly provided at the bottom of the extrusion block, and a groove is provided at the top of the movable block to cooperate with the slider. A second spring for support is fixedly connected between the slider and the groove.

[0013] Preferably, the adjusting component includes a fixed shell, a first bevel gear is rotatably mounted at the bottom of the inner cavity of the fixed shell, a second bevel gear is meshed at the top of the first bevel gear, a control rod penetrating the fixed shell is mounted on the side of the second bevel gear, a screw rod penetrating the top of the fixed shell is fixedly provided at the top of the first bevel gear, and a threaded tube threadedly connected to the screw rod is fixedly provided at the bottom of the cross plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model provides a stable power source for the clamp by using a cylinder, enabling it to quickly and stably drive the clamp to hold the busbar pipe. The unique internal structure of the clamp allows the grippers to slide flexibly within the movable groove, and through cooperation with the positioning plate, it can achieve position positioning. This allows for adaptive adjustment and secure clamping according to the diameter of the busbar pipe, ensuring the busbar pipe remains stable during welding and avoiding welding quality problems caused by shaking or displacement, thus improving welding accuracy and quality.

[0016] 2. This utility model also utilizes the triangular pressure block on the extruder to cooperate with the adjusting block, with both surfaces being inclined. When the extruder is pressed down, the inclined surface drives the adjusting block to move the clamping plate upward. The cooperation of the slider, groove, and spring allows for the allowance for the displacement distance of the busbar extrusion jaws, further improving the strength of the jaws in holding the busbar and reducing the existence of clamping gaps. Simultaneously, the supporting effect of the first spring on the extruder ensures that the extruder can automatically reset when the busbar is placed or removed, facilitating operation and maintaining the stability and reliability of the entire clamping structure.

[0023] like Figures 1 to 5As shown, this utility model relates to a combined busbar welding bracket, including a base 1. Two telescopic rods 2 are fixedly installed on the top of the base 1. An adjusting component 3 is fixedly installed at the middle of the top of the base 1. A horizontal plate 4 is fixedly connected to the top of the two telescopic rods 2. A cylinder 5 is fixedly installed on the top of the horizontal plate 4. A clamp 6 for clamping the busbar is fixedly installed on the top of the cylinder 5. The overall height can be adjusted by the cooperation of the telescopic rods 2 and the adjusting component 3. The clamp 6 can be adjusted to a suitable position for clamping the busbar by the cooperation of the cylinder 5.

[0024] The clamp 6 includes a support block 601. The top of the support block 601 has two parallel movable slots 602. A limiting plate 603 is fixedly installed in the middle of each movable slot 602. A gripper 7 is slidably installed between the two movable slots 602. Inside each movable slot 602, two positioning plates 9 are movably installed to cooperate with the gripper 7 for limiting. The movable slots 602 make it easy for the gripper 7 on both sides to slide and adjust its position. With the limiting of the positioning plates 9, it can be used to clamp busbars of different sizes.

[0025] In this embodiment of the present invention, a pressing member 8 is installed through the wall of the limiting plate 603. Two adjusting blocks 604 are movably installed at the bottom of the inner cavity of the movable groove 602, which are attached to both sides of the pressing member 8. The bottom side of the adjusting block 604 is attached to the end of the positioning plate 9. The contact surfaces of the adjusting block 604 and the positioning plate 9 are both upwardly inclined. A first spring 605 supporting the pressing member 8 is fixedly installed at the center of the bottom of the inner cavity of the movable groove 602. The pressing member 8 can be squeezed downward when the busbar is placed, which will press the adjusting block 604 to move towards the positioning plate 9, thereby squeezing the positioning plate 9 upward and engaging with the gripper 7 to achieve the limiting effect. The support of the first spring 605 can retract after the pressing member 8 moves downward, so that it can rebound and reset when the pressure is lost, achieving the effect of automatic adjustment.

[0026] In an embodiment of this utility model, the gripper 7 includes a pressing block 701. A movable block 702, which fits against the side of the movable groove 602, is movably mounted on the bottom of the pressing block 701. A locking member 703, which cooperates with the locking plate 9, is fixedly provided on the bottom of the movable block 702. The top of the locking plate 9 has several locking grooves 901 that are adapted to and inserted into the locking member 703. Several ball bearings 902, which reduce movement resistance, are embedded in the side of the locking plate 9 that fits against the movable groove 602. The combination of the locking grooves 901 and the locking member 703 can restrict the displacement of the movable block 702. The ball bearings 902 on the side of the locking plate 9 can reduce resistance when moving upwards and also reduce resistance when resetting, thus enhancing the automatic engagement effect.

[0027] In an embodiment of this utility model, the extrusion member 8 includes a fixed rod 801. A triangular pressure block 802 that cooperates with the adjusting block 604 is fixedly provided at the bottom of the fixed rod 801. The contact surfaces of the triangular pressure block 802 and the adjusting block 604 are both downward inclined surfaces. Through the contact of the inclined surfaces, the adjusting block 604 can be pressed to move downward, thereby causing the adjusting block 604 to press the positioning plate 9 upward. A limiting hole 803 is provided between the fixed rod 801 and the triangular pressure block 802. It cooperates with the limiting rod 606 provided at the bottom of the inner cavity of the movable groove 602 to achieve the effect of vertical limiting movement.

[0028] In an embodiment of this utility model, a slider 704 is fixedly provided at the bottom of the extrusion block 701, and a groove 705 that cooperates with the slider 704 is provided at the top of the movable block 702. A second spring 706 for support is fixedly connected between the slider 704 and the groove 705. The cooperation between the slider 704 and the groove 705 can reserve a displacement distance for the extrusion block 701, which is convenient for the busbar to move to a fixed position and enhances the stability of clamping and limiting during welding.

[0029] In an embodiment of this utility model, the adjusting component 3 includes a fixed shell 301. A first bevel gear 302 is rotatably mounted at the bottom of the inner cavity of the fixed shell 301. A second bevel gear 303 is meshed with the top of the first bevel gear 302. A control rod 304 that penetrates the fixed shell 301 is mounted on the side of the second bevel gear 303. A screw 305 that penetrates the top of the fixed shell 301 is fixedly provided at the top of the first bevel gear 302. A threaded tube 401 that is threadedly connected to the screw 305 is fixedly provided at the bottom of the horizontal plate 4. Through cooperation, the screw 305 can rotate, causing the threaded tube 401 to move up and down under the thread limit, thereby achieving the effect of height adjustment.

[0030] Working Principle: This embodiment provides a combined busbar welding bracket. During overall height adjustment, firstly, rotating the control lever 304 drives the second bevel gear 303 to rotate. The second bevel gear 303 meshes with the first bevel gear 302, causing the first bevel gear 302 to rotate. The screw 305 at the top of the first bevel gear 302 then rotates accordingly. Since the threaded tube 401 at the bottom of the horizontal plate 4 is threadedly connected to the screw 305, when the screw 305 rotates, the threaded tube 401 drives the horizontal plate 4 to move up and down along the screw 305, thereby adjusting the height of the horizontal plate 4. Simultaneously, the telescopic rod 2 provides stable support and assists in telescopic movement. After the height adjustment is complete, the clamp 6 can be moved to a suitable position by the cylinder 5 to begin clamping and fixing the busbar. When the busbar is placed above the clamp 6, it first contacts the clamps 7 on both sides. Through compression, the clamps 7 can move in opposite directions, maintaining contact with the sides of the busbar. When the busbar moves down to contact the top of the clamping element 8, the clamping element 8 is pressed downwards by external force. During this downward movement, the first spring 605 contracts, and the triangular pressure block 802 at the bottom of the clamping element 8 presses against the adjusting block 604. Because the contact surfaces of the adjusting block 604 and the positioning plate 9 are both upwardly inclined, the adjusting block 604 moves to both sides. Under the pressure of the adjusting block 604, the positioning plate 9 is pushed upwards within the movable groove 602. Simultaneously, the upward movement pulls the elastic band 607 at the bottom, causing the positioning groove 901 at the top of the positioning plate 9 to connect with the positioning element 703 at the bottom of the clamps 7. This fixes the position of the clamps 7. After the clamps 7 are fixed, the busbar is held... Continuing to move downwards, the pressing block 701 can be displaced, causing the slider 704 to move inside the slide groove 705. At the same time, the second spring 706 is compressed and contracted, causing the slider 704 to reach a position where it cannot move, thus completing the limiting clamping of the busbar. After the welding operation is completed, the pressing component 8 can be released by moving the busbar upwards. Under the action of the first spring 605, the pressing component 8 returns to its original position upwards, and the clamping plate 9 can return to its original position under the rebound action of the elastic band 607. This compresses the adjusting block 604 to move towards the center, thereby releasing the limiting of the gripper 7. It then automatically returns to its original position under the rebound action of the telescopic support rod 10 set on the inner wall of the movable groove 602, completing the release of the limiting operation. This automatic clamping and releasing operation method simplifies the operation steps, improves the flexibility of operation, and is suitable for clamping and limiting busbars of different sizes, effectively improving the structural fit effect.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
