Description

TECHNICAL FIELD

[0002] As a key conductor for transmitting large current in the power system, the performance of the connection part of the busbar directly affects the stability of power supply. Welding can effectively eliminate the gap between the busbar connections, reduce the contact resistance, avoid local heating due to excessive resistance, and prevent overheating burnout or insulation aging problems during long-term operation. In electrical engineering construction, the core purpose of welding two busbars is to build a reliable conductive connection and structural fixation.

However, in the existing technology, the busbar needs to be transferred between different devices during the polishing and welding key processes. This process not only easily causes positioning deviation, but also requires workers to transfer the busbar, which has limited operation efficiency. The current equipment cannot realize integrated operation of these processes, and it is difficult to meet the dual requirements of operation efficiency and processing accuracy in modern construction scenarios.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0041] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0042] Reference Figures 1-10The utility model provides a welding equipment for electrical engineering construction, including workbench 9, dust extraction box 3, workbench 9 is polished disc 101 one side and is fixedly connected with dust extraction box 3 through bolt, nut and gasket, the both sides of dust extraction box 3 are symmetrical and are rotatably connected with the closed door 4 through pin shaft and bearing cooperation, the top of dust extraction box 3 is fixedly connected with the edge cover 2 through bolt, nut and gasket, the edge cover 2 blocks the top of one closed door 4, and the guide assembly is arranged on the opposite side of polished disc 101 of dust extraction box 3, and the guide assembly drives welding torch to move along the contact position of two sections of busbar.

[0043] The guide assembly includes top horizontal broken frame 5, top motor 6, horizontal moving screw 61 and mounting seat 7, the top horizontal broken frame 5 includes horizontal section and vertical section, the vertical section of top horizontal broken frame 5 is fixedly connected at the top of workbench 9 through bolt, nut and gasket, the horizontal section of top horizontal broken frame 5 is fixedly connected with top motor 6 at the edge position through bolt, nut and gasket, the output end of top motor 6 is fixedly connected with horizontal moving screw 61 through bolt, nut and gasket, and mounting seat 7 is screwed into the outer wall of horizontal moving screw 61, and the mounting seat 7 is used for fixing the welding torch in the prior art.

[0044] In addition, in order to ensure that the mounting seat 7 is stable when moving horizontally on the horizontal moving screw 61, the horizontal section of the top horizontal broken frame 5 is further provided with a slot with the same width as the mounting seat 7, and the mounting seat 7 extends into the slot, and finally the length of the horizontal moving screw 61 limits the horizontal moving distance of the mounting seat 7, and the horizontal moving distance of the mounting seat 7 is the length of the welding seam of the two sections of busbar, so the length of the horizontal moving screw 61 needs to be appropriately set.

[0045] The closed door 4 blocked by the edge cover 2 is the closed door 4 away from the side face of the guide assembly, and the closed door 4 forms a structure similar to a "one-way door" under the blockage of the edge cover 2, and the two sections of busbar after polishing enter the dust extraction box 3 for dust removal, and in this process, the two sections of busbar will first push the closed door 4 to lift and then put down.

[0046] When the two sections of busbar enter the dust extraction box 3, the two closed doors 4 and the dust extraction box 3 form a closed chamber, and since the two sections of busbar will be polished by the polishing disc 101, grinding slag will inevitably remain at the ends of the two sections of busbar, which will seriously affect the welding quality at the contact position of the two sections of busbar if not cleaned, and the dust extraction box 3 needs to be externally connected with a dust extractor of a factory during actual use, and the dust remaining at the ends of the two sections of busbar can be sucked away when the two sections of busbar pass through the dust extraction box 3.

[0047] The workbench 9 top is symmetrically provided with busbar fixing assemblies, the busbar fixing assemblies are used as transfer containers of two sections of busbars to be welded, the busbar fixing assemblies comprise fixing seats 21, fixing tables 24 and inverted U-shaped frames 241, the fixing tables 24 are rotatably connected with the fixing seats 21 through pin shafts and bearings, the inverted U-shaped frames 241 are fixedly connected with the top of the fixing tables 24 through bolts, nuts and washers, the inverted U-shaped frames 241 are screwed into the top of the press screw 22, the press rod 23 is rotatably connected with the bottom of the press screw 22 through a pin shaft and a bearing, the press rod 23 and the fixing table 24 form a simple fixing structure for the busbar plate, the press rod 23 is equal in width with the inverted U-shaped frame 241, when the press screw 22 rotates, the two ends of the press rod 23 are limited by the inverted U-shaped frame 241, and only move upward in the vertical direction, in addition, in order to facilitate the rotation of the press screw 22, a hand wheel is further arranged at the top of the press screw 22.

[0048] In order to assist in blocking one end of the busbar when the busbar is fixed on the fixing table 24, an auxiliary blocking assembly is further arranged in the busbar fixing assembly, the auxiliary blocking assembly comprises blocking magnets 29 and repelling magnets 11, the two repelling magnets 11 are symmetrically fixedly connected on the top of the workbench 9 through bolts, nuts and washers, the blocking magnets 29 are movably inserted into the fixing table 24, the outer wall of the blocking magnet 29 is fixedly connected with one end of the retaining spring 291 through bolts, nuts and washers, the other end of the retaining spring 291 is fixedly connected with the bottom of the fixing table 24 through bolts, nuts and washers, and the opposite faces of the blocking magnet 29 and the repelling magnet 11 have the same polarity.

[0049] When the blocking magnet 29 is not repelled by the repelling magnet 11, the retaining spring 291 is in the original length, at this time, the blocking magnet 29 is retracted in the inner cavity of the fixing table 24, when the two fixing tables 24 are located at the edge position of the workbench 9, the blocking magnet 29 is exposed from the top of the fixing table 24 and repelled by the repelling magnet 11, the user can quickly abut one end of the busbar against the blocking magnet 29, and quickly fix the busbar by using the press rod 23, when the fixing table 24 moves to one side of the guide assembly, when the blocking magnet 29 is not repelled by the repelling magnet 11, the retaining spring 291 restores to the original length, at this time, the blocking magnet 29 is retracted in the inner cavity of the fixing table 24, and the two busbar ends are no longer blocked, so that the two busbar ends are facilitated to be chamfered and butted.

[0050] One of the busbar fixing assemblies is a posture adjusting assembly, which adjusts the inclination angle of the fixing table 24. A mounting groove 95 is formed in the bottom of the workbench 9. A polishing motor 10 is fixedly connected inside the mounting groove 95 by bolts, nuts and washers. A polishing disc 101 is fixedly connected to the output end of the polishing motor 10 by bolts, nuts and washers. The polishing disc 101 extends out of the top of the workbench 9. Since the polishing motor 10 occupies a certain space, a support plate 1 needs to be fixedly connected to the bottom of the workbench 9 by bolts, nuts and washers. At the same time, the two ends of the busbar to be welded are polished. When the fixing table 24 reaches the position of the polishing disc 101, the end of the busbar fixed by the fixing table 24 is inclined downward, which facilitates the polishing disc 101 to perform micro-chamfering on the end of the busbar. In order to avoid the collision between the two ends of the busbar when they are polished by the polishing disc 101, the thickness of the polishing disc 101 needs to be set relatively thick.

[0051] The posture adjusting assembly comprises a vertical plate 30, a driving cross column 26, a vertical tooth rod 28 and a driven gear 27. The driven gear 27 is fixedly connected at one end of the rotating shaft of the fixing table 24 by bolts, nuts and washers. The driven gear 27 stably engages with the vertical tooth rod 28. The vertical tooth rod 28 is movably inserted into one side of the fixing base 21. The vertical tooth rod 28 has a horizontal T-shaped top view cross-sectional dimension. The position where the vertical tooth rod 28 is movably inserted into the fixing base 21 is provided with a corresponding-shaped air slot, which limits the vertical tooth rod 28 to only move in the vertical direction. The vertical plate 30 is fixedly connected at the edge position of the top of the workbench 9 by bolts, nuts and washers. The side surface of the vertical plate 30 is sequentially provided with a retaining horizontal groove 301, a V-shaped groove 302 and a restoring horizontal groove 303. The side surface of the vertical tooth rod 28 is fixedly connected with the driving cross column 26 by bolts, nuts and washers. The driving cross column 26 is movably inserted into the retaining horizontal groove 301, the V-shaped groove 302 or the restoring horizontal groove 303.

[0052] When the driving cross column 26 moves along the retaining horizontal groove 301, the V-shaped groove 302 or the restoring horizontal groove 303, the vertical tooth rod 28 will be forced to move in the vertical direction. The retaining horizontal groove 301 and the restoring horizontal groove 303 are parallel to the horizontal plane. It is obvious that the vertical distance between the retaining horizontal groove 301 and the restoring horizontal groove 303 is the vertical displacement distance of the vertical tooth rod 28. After the vertical tooth rod 28 completes the complete vertical displacement, it will drive the fixing table 24 to overturn by a certain angle through the driven gear 27. Finally, the busbar at the top of the fixing table 24 is overturned and kept at a certain inclination angle. Finally, in order to protect the posture adjusting assembly, the side surface of the fixing base 21 is also fixedly connected with the edge folding cover 25 by bolts, nuts and washers. The bottom and the side surface of the edge folding cover 25 are both open surfaces, which leave space for the displacement of the driving cross column 26 and the vertical tooth rod 28.

[0053] A transfer assembly is arranged at the top edge position of the workbench 9, which drives the busbar on the busbar fixing assembly to move horizontally along the workbench 9 to sequentially perform polishing, butt joint and welding work. The transfer assembly comprises a transfer motor 8, a transfer screw 14, a driving block 19, a horizontal moving seat 18 and a path control assembly. An edge groove 96 is formed at the top edge position of the workbench 9. The transfer screw 14 is rotatably connected to the inside of one of the edge grooves 96 through a pin shaft and a bearing. The auxiliary screw 15 is rotatably connected to the inside of the other edge groove 96 through a pin shaft and a bearing. The transfer motor 8 is fixedly connected to the side surface of the workbench 9 through bolts, nuts and washers. The output end of the transfer motor 8 is fixedly connected with the transfer screw 14 through bolts, nuts and washers.

[0054] The driving pulleys 17 are fixedly connected to the ends of the transfer screw 14 and the auxiliary screw 15 through bolts, nuts and washers. The same common belt 16 is sleeved on the outer walls of the two driving pulleys 17. When the transfer motor 8 drives the transfer screw 14 to rotate, the auxiliary screw 15 can be driven to rotate through the common belt 16 and the driving pulleys 17. The auxiliary screw 15 and the transfer screw 14 rotate in the same direction and at the same speed. Further, in order to ensure the synchronous rotation of the auxiliary screw 15 and the transfer screw 14, the common belt 16 is selected as a synchronous belt, the driving pulleys 17 are selected as synchronous pulleys, and the transfer motor 8 is selected as a servo motor with higher precision. Finally, in order to protect the common belt 16 and the driving pulleys 17, the edge cover 12 is fixedly connected to the positions of the common belt 16 and the two driving pulleys 17 through bolts, nuts and washers.

[0055] The driving blocks 19 are screwed into the outer walls of the auxiliary screw 15 and the transfer screw 14. The horizontal moving seat 18 is fixedly connected to the top of the driving block 19 through bolts, nuts and washers. In order to reduce the horizontal moving resistance of the horizontal moving seat 18, the edge guide rail 13 is movably inserted into the side surface of the horizontal moving seat 18. The horizontal moving seat 18 is provided with an avoiding groove 181 at the corresponding position of the edge guide rail 13. The extension cross bar 20 is fixedly connected to the side surface of the horizontal moving seat 18 through bolts, nuts and washers. The extension cross bar 20 is provided with a horizontal moving groove 201 at the top. The path control assembly controls the two fixed seats 21 to move towards each other when moving horizontally along the workbench 9. The path control assembly comprises a horizontal moving block 210 and a driving vertical column 2100. The horizontal moving block 210 is fixedly connected to the bottom of the fixed seat 21 through bolts, nuts and washers. The driving vertical column 2100 is screwed into the bottom of the horizontal moving block 210 after the horizontal moving block 210 extends into the horizontal moving groove 201. The first inclined groove 91, the polishing horizontal groove 92, the second inclined groove 93 and the close horizontal groove 94 are symmetrically formed at the top of the workbench 9. The driving vertical column 2100 is movably inserted into the first inclined groove 91, the polishing horizontal groove 92, the second inclined groove 93 or the close horizontal groove 94.

[0056] The specific implementation steps and principles of the application are as follows:

[0057] In the initial state, the dust extraction box 3 is connected to the top of the dust extraction machine, and in the initial state, the two horizontal moving seats 18 are located at the top edge of the workbench 9. At this time, the two repulsion magnets 11 are directly below the blocking magnets 29, and the two blocking magnets 29 are exposed from the top of the fixed table 24 due to the repulsion of the repulsion magnets 11. The user inserts the two busbars to be welded into the space below the pressing rod 23, rotates the pressing screw 22, and the pressing screw 22 drives the pressing rod 23 to move downward to clamp the busbars. Until the end of the busbar is blocked by the blocking magnet 29, at this time, the driving vertical column 2100 is in the first inclined groove 91, and the two ends of the busbar are at the farthest distance, and one end of the driving horizontal column 26 is in the holding horizontal groove 301, and the fixed table 24 is kept in a horizontal state by the vertical rack 28 and the driven gear 27.

[0058] The user starts the transfer motor 8, which drives the transfer screw 14 to rotate. The transfer screw 14 drives the auxiliary screw 15 to rotate through the driving pulley 17 and the common belt 16. The transfer screw 14 moves the horizontal moving seat 18 on the top of the driving block 19 to the polishing disc 101. When the driving vertical column 2100 moves to the polishing horizontal groove 92, it drives the two busbars on the top of the fixed seat 21 to approach a certain distance. At the same time, the driving horizontal column 26 moves from the holding horizontal groove 301 to the V-shaped groove 302, and the fixed table 24 is kept at a certain inclination by the vertical rack 28 and the driven gear 27. The opposite ends of the two busbars are inclined downward, and after passing through the two sides of the polishing disc 101, the opposite ends of the two busbars are slightly chamfered.

[0059] When the driving vertical column 2100 is ready to move from the polishing horizontal groove 92 to the second inclined groove 93, and the driving horizontal column 26 moves from the V-shaped groove 302 to the recovery horizontal groove 303, the fixed table 24 is restored to a horizontal state by the vertical rack 28 and the driven gear 27.

[0060] When the driving vertical column 2100 moves from the second inclined groove 93 to the close horizontal groove 94, the two fixed seats 21 continue to move towards each other, and the two busbar ends on the fixed table 24 are completely attached. The welding gun is fixed on the top of the mounting seat 7, and the top motor 6 is started. The top motor 6 drives the mounting seat 7 to move horizontally through the horizontal moving screw 61, and the welding gun moves along the joint of the two busbars to weld the two busbars.

[0061] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes within the technical scope disclosed by the present application and according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
