Description

Technical Field

[0001] This invention relates to the field of welding fixtures for busbar trunking production, and particularly to a welding fixture for busbar trunking production. Background Technology

[0002] Busbar trunking is a device used for power transmission in power systems, primarily replacing traditional cable transmission methods. It is commonly used in the power distribution systems of large buildings, factories, and industrial facilities. The main function of busbar trunking is to transmit electrical energy from substations or distribution rooms to various load points, providing efficient, safe, and reliable power transmission. Welding fixtures used in busbar trunking production are specialized tools used in the manufacturing process to fix the various components of the busbar trunking (such as the busbar trunking housing, conductive strips, and terminals) in suitable positions to facilitate efficient and precise welding operations.

[0003] The prior art publication CN212384915U provides a welding fixture device for busbar trunking shells. It features welding clamps hinged to both sides of a support rod, and an adjusting screw clamped onto an inclined panel. Adjusting the length of the adjusting screw protruding from the inclined panel adjusts the rotation angle of the welding clamps, ensuring they meet the required angle for the busbar trunking shell. The clamps are then used to assemble and fix the busbar trunking shell before welding. This method is simple and convenient, effectively improving the welding accuracy and quality of the busbar trunking shell, while also increasing production efficiency.

[0004] Existing technology uses adjusting screws that are close to each other to clamp the busbar. However, when clamping bent busbars, which have specific bending angles and shapes, the straight clamping method of the adjusting screws may not be able to fit the shape of the busbar tightly, resulting in unstable clamping. This can easily lead to displacement or shaking during welding, affecting welding accuracy.

[0005] In summary, the existing technology lacks a technique for using welding fixtures that are compatible with the shape of bent busbars. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a welding fixture for busbar production.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a welding fixture for busbar production, comprising a base, a fixed column fixedly connected to the base, a top seat fixedly connected to the top of the fixed column, a welding fixture mechanism rotatably connected to the top seat, a rotating seat rotatably connected to the outer wall of the bottom end of the fixed column, a plurality of placement racks fixedly connected to the rotating seat, an automatic feeding mechanism rotatably connected to the placement racks, and a movable limiting plate rotatably connected to one side of the placement racks.

[0008] Preferably, a first motor is fixedly connected to the inner wall of the base, an adjusting wheel is fixedly connected to the output end of the first motor, and a guide ring is fixedly connected to the base, with one side of the guide ring having an inwardly concave structure.

[0009] Preferably, a rotating shaft is rotatably connected to both sides of the top of the fixed column, and a drive wheel is fixedly connected to the outer wall of the rotating shaft.

[0010] Preferably, the welding fixture mechanism includes a second motor, which is fixedly connected to the inner wall of the fixed column. A sector gear is fixedly connected to the output end of the second motor, and the sector gear meshes with two driving wheels for transmission. An electric push rod is fixedly connected to the output end of the second motor through the bottom of the top seat and to the upper side. A connecting frame is fixedly connected to the output end of the electric push rod.

[0011] Preferably, a bending frame is fixedly connected to the bottom end of the connecting frame, a third motor is fixedly connected to the inner wall of one end of the bending frame, a universal joint assembly is fixedly connected to the output end of the third motor, the universal joint assembly is rotatably connected to the bending frame, multiple worm gears are fixedly connected to the outer wall of the universal joint assembly, worm wheels are meshed and driven on both sides of the worm gears, a rotating rod is fixedly connected to the worm wheel, the bottom end of the rotating rod is rotatably connected to the bending frame, and an abutment wheel is rotatably connected to one end of the rotating rod.

[0012] Preferably, an annular rack is fixedly connected to the lower inner wall of the rotating seat, and the annular rack is meshed with the adjusting wheel for transmission. Multiple rollers are rotatably connected to the lower surface of the rotating seat in an annular structure, and the rollers are in sliding contact with the top surface of the base.

[0013] Preferably, the placement rack has multiple bent busbar grooves placed on it, the inner wall of the bent busbar groove abutting the outer wall of the abutting wheel, and a fixed limiting plate is fixedly connected to one side of the placement rack, the fixed limiting plate being adapted to one side of the bent busbar groove.

[0014] Preferably, the automatic feeding mechanism includes a reciprocating screw, the bottom end of which is rotatably connected to the placement frame, a driven wheel is fixedly connected to the top end of the reciprocating screw, the driven wheel is meshed with the driving wheel for transmission, a movable frame is slidably fitted on the outer wall of the reciprocating screw, and a lifting plate is fixedly connected to one end of the movable frame through a fixed limiting plate.

[0015] Preferably, one side of the movable limiting plate is adapted to the other side of the bent busbar groove. A transmission wheel is fixedly connected to the bottom end of the movable limiting plate. A transmission rack is meshed and driven on the lower side of the transmission wheel. A T-shaped frame is fixedly connected to the transmission rack. One side of the T-shaped frame is slidably fitted with the placement frame. Both ends of the other side of the T-shaped frame are fixedly connected with tension springs. The other end of the tension springs is fixedly connected to the placement frame. A contact shaft is rotatably connected to the lower side of the T-shaped frame. The outer wall of the contact shaft is slidably in contact with the outer wall of the guide ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting a bending frame that matches the shape of the bent busbar, and setting rotatable rotating rods at multiple positions on the bending frame, the rotating rods will drive the abutment wheel to abut against the inner wall of the bent busbar, thereby achieving clamping of the bent busbar. This can avoid the loosening or deformation problems caused by the incompatibility of the clamping method in traditional fixtures, thereby improving the stability of the welding process.

[0018] 2. By setting up an automatic feeding mechanism, while the welding fixture mechanism rotates to reposition and weld the bent busbar, it will drive the automatic feeding mechanism to lift the bent busbars to be welded on one side of the placement frame in sequence for easy clamping. At the same time, it will drive the automatic feeding mechanism on the other side of the placement frame to descend in sequence for easy placement of the welded bent busbar. By combining the automatic feeding mechanism with the repositioning function of the welding fixture, the welding of bent busbars is automated, efficient and standardized, which not only improves production efficiency and welding quality, but also reduces costs and safety risks.

[0019] 3. By setting a rotating seat and a movable limit plate, combined with the function of the guide ring, efficient repositioning and convenient loading and unloading are achieved during the welding process of the bent busbar trunking. This not only improves welding efficiency, but also simplifies the operation process, enhances safety, and saves labor costs. Attached Figure Description

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] like Figures 1-9 The welding fixture for busbar trunking production shown includes a base 1, a fixed column 2 fixedly connected to the base 1, a top seat 3 fixedly connected to the top of the fixed column 2, a welding fixture mechanism 4 rotatably connected to the top seat 3, a rotating seat 5 rotatably connected to the outer wall of the bottom end of the fixed column 2, multiple placement racks 6 fixedly connected to the rotating seat 5, an automatic feeding mechanism 7 rotatably connected to the placement racks 6, and a movable limiting plate 8 rotatably connected to one side of the placement racks 6.

[0032] like Figure 3As shown, a first motor 101 is fixedly connected to the inner wall of the base 1, an adjusting wheel 102 is fixedly connected to the output end of the first motor 101, and a guide ring 103 is fixedly connected to the base 1. One side of the guide ring 103 has an inwardly concave structure.

[0033] like Figure 4 As shown, a rotating shaft 202 is rotatably connected to both sides of the top of the fixed column 2, and a drive wheel 201 is fixedly connected to the outer wall of the rotating shaft 202.

[0034] like Figure 5 , Figure 6 As shown, the welding fixture mechanism 4 includes a second motor 401, which is fixedly connected to the inner wall of the fixed column 2. A sector gear 402 is fixedly connected to the output end of the second motor 401. The sector gear 402 meshes with two drive wheels 201 respectively. An electric push rod 403 is fixedly connected to the output end of the second motor 401 through the bottom of the top seat 3 and to the upper side. A connecting frame 404 is fixedly connected to the output end of the electric push rod 403.

[0035] A bending frame 405 is fixedly connected to the bottom of the connecting frame 404. A third motor 406 is fixedly connected to the inner wall of one end of the bending frame 405. A universal joint assembly 407 is fixedly connected to the output end of the third motor 406. The universal joint assembly 407 is rotatably connected to the bending frame 405. Multiple worm gears 408 are fixedly connected to the outer wall of the universal joint assembly 407. Worm wheels 409 are meshed on both sides of each worm gear 408. A rotating rod 410 is fixedly connected to the worm wheel 409. The bottom end of the rotating rod 410 is rotatably connected to the bending frame 405. An abutment wheel 411 is rotatably connected to one end of the rotating rod 410. The outer wall of the abutment wheel 411 is covered with a rubber layer, which serves to protect the inner wall of the bent busbar 601. The electric actuator 403 drives the connecting frame 404 to move downward, so that the bending frame 405 on the connecting frame 404 can be inserted into the inside of the bent busbar groove 601. Then, the third motor 406 drives the connected universal joint assembly 407 to rotate. At this time, the universal joint assembly 407 will drive the connected worm gear 408 to rotate, so that the worm gear 408 can drive the worm wheels 409 on both sides to rotate, so that the worm wheels 409 can drive the connected rotating rod 410 to rotate, so that the abutting wheel 411 on the rotating rod 410 can abut against the inside of the bent busbar groove 601.

[0036] By setting a bending frame 405 that is adapted to the shape of the bent busbar 601, and setting rotatable rotating rods 410 at multiple positions of the bending frame 405, the rotating rods 410 will drive the abutment wheel 411 to abut against the inner wall of the bent busbar 601 when they rotate, thereby achieving clamping of the bent busbar 601. This can avoid the loosening or deformation problems caused by the incompatibility of the clamping method in traditional fixtures, thereby improving the stability of the welding process.

[0037] like Figure 7 As shown, a ring rack 501 is fixedly connected to the lower inner wall of the rotating seat 5. The ring rack 501 meshes with the adjusting wheel 102 for transmission. Multiple rollers 502 are rotatably connected to the lower surface of the rotating seat 5 in a ring structure. The rollers 502 are in sliding contact with the top surface of the base 1. The rollers 502 make the rotating seat 5 easier to rotate.

[0038] like Figure 8 As shown, multiple bent busbar troughs 601 are placed on the placement rack 6. The inner wall of the bent busbar trough 601 abuts against the outer wall of the abutment wheel 411. A fixed limiting plate 602 is fixedly connected to one side of the placement rack 6, and the fixed limiting plate 602 is adapted to one side of the bent busbar trough 601.

[0039] like Figure 8 As shown, the automatic feeding mechanism 7 includes a reciprocating screw 701. The bottom end of the reciprocating screw 701 is rotatably connected to the placement frame 6. A driven wheel 702 is fixedly connected to the top end of the reciprocating screw 701. The driven wheel 702 is meshed with the driving wheel 201 for transmission. A movable frame 703 is slidably fitted on the outer wall of the reciprocating screw 701. One end of the movable frame 703 passes through the fixed limiting plate 602 and is fixedly connected to a lifting plate 704. The second motor 401 drives the connected electric push rod 403 to rotate clockwise, thereby moving the bending frame 405 to move above the bent busbar groove 601 to be welded. At this time, the second motor 401 will drive the drive wheel 201 on one side to rotate through the connected sector gear 402, so that the drive wheel 201 can drive the reciprocating screw 701 connected to the driven wheel 702 to rotate, so that the reciprocating screw 701 can drive the lifting plate 704 connected to the moving frame 703 to move up by the height of the bent busbar groove 601.

[0040] like Figure 9 As shown, one side of the movable limiting plate 8 is adapted to the other side of the bent busbar groove 601. A transmission wheel 801 is fixedly connected to the bottom end of the movable limiting plate 8. A transmission rack 802 is meshed on the lower side of the transmission wheel 801. A T-shaped frame 803 is fixedly connected to the transmission rack 802. One side of the T-shaped frame 803 is slidably fitted with the placement frame 6. Both ends of the other side of the T-shaped frame 803 are fixedly connected to tension springs 804. The other end of the tension springs 804 is fixedly connected to the placement frame 6. A contact shaft 805 is rotatably connected to the lower side of the T-shaped frame 803. The outer wall of the contact shaft 805 is in slidable contact with the outer wall of the guide ring 103. The tension springs 804 will drive the T-shaped frame 803 to automatically reset. The contact shaft 805 will move out from the concave part of the guide ring 103. At this time, it will drive the T-shaped frame 803 connected to the contact shaft 805 to move, so that the T-shaped frame 803 drives the connected transmission rack 802 to move, so that the transmission rack 802 can drive the movable limit plate 8 connected to the transmission wheel 801 to rotate and stand up.

[0041] Working principle: When welding the bent busbar 601 is required, the first motor 101 drives the connected adjusting wheel 102 to rotate, so that the adjusting wheel 102 drives the rotating seat 5 connected to the ring rack 501 to rotate clockwise, so that the placement frame 6, on which the bent busbar 601 to be welded is placed, rotates to one side. At this time, the driven wheel 702 connected to the reciprocating screw 701 on the placement frame 6 meshes with the driving wheel 201.

[0042] At this time, the contact shaft 805 will move out from the concave part of the guide ring 103, which will drive the T-shaped frame 803 connected to the contact shaft 805 to move, so that the T-shaped frame 803 drives the connected transmission rack 802 to move, so that the transmission rack 802 can drive the movable limiting plate 8 connected to the transmission wheel 801 to rotate and stand up, and cooperate with the fixed limiting plate 602 to limit the bent busbar groove 601.

[0043] Then, the second motor 401 drives the connected electric push rod 403 to rotate clockwise, thereby moving the bending frame 405 to move above the bent busbar groove 601 to be welded. At this time, the second motor 401 will drive the drive wheel 201 on one side to rotate through the connected sector gear 402, so that the drive wheel 201 can drive the reciprocating screw 701 connected to the driven wheel 702 to rotate, so that the reciprocating screw 701 can drive the lifting plate 704 connected to the moving frame 703 to move up by the height of the bent busbar groove 601.

[0044] Then, the electric actuator 403 drives the connecting frame 404 to move downward, so that the bending frame 405 on the connecting frame 404 can be inserted into the inside of the bent busbar trough 601. Then, the third motor 406 drives the connected universal joint assembly 407 to rotate. At this time, the universal joint assembly 407 will drive the connected worm gear 408 to rotate, so that the worm gear 408 can drive the worm wheels 409 on both sides to rotate, so that the worm wheels 409 can drive the connected rotating rod 410 to rotate, so that the abutment wheel 411 on the rotating rod 410 can abut against the inside of the bent busbar trough 601 to achieve clamping. Then, the electric actuator 403 drives the bending frame 405 to move upward, and then the second motor 401 continues to drive the electric actuator 403 to rotate, driving the bent busbar trough 601 to be welded to rotate to the other side for welding.

[0045] At this time, the second motor 401 will drive the drive wheel 201 on the other side to rotate through the connected sector gear 402, so that the drive wheel 201 can drive the reciprocating screw 701 connected to the driven wheel 702 to rotate, so that the reciprocating screw 701 can drive the lifting plate 704 connected to the moving frame 703 to move down by the height of a bent busbar 601, which is convenient for placing the welded bent busbar 601.
