Description

Technical Field

[0001] The invention relates to the technical field of bus duct production, and in particular to a processing tool for producing a flame-retardant, fire-resistant and waterproof bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] At present, in the production of flame-retardant, fire-resistant and waterproof bus duct, it is necessary to wrap the busbar with polyester film in advance, and then assemble four side panels on the outside of the stacked busbars to form the bus duct shell to complete the processing of a bus duct. However, some special wiring areas need to be deflected by 90 degrees, and then the production and processing of right-angle bus ducts are also required. For right-angle bus ducts, the bending of the busbar is very easy, but the production of the equipped right-angle shell requires staff to perform cutting and welding. In the prior art, the side panels of the right-angle busbars are mostly manually spot welded, and the welding is completed one by one.

DETAILED DESCRIPTION

[0016] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0017] Reference Figure 1-Figure 7A processing tool for the production of flame-retardant, fire-resistant and waterproof bus ducts, including a processing table 1, a moving mechanism is provided at the upper end of the processing table 1, and the moving mechanism includes four U-shaped blocks 2 distributed in a rectangular shape and fixedly connected to the upper end of the processing table 1, and a sprocket is rotatably connected between the left and right inner walls of each U-shaped block 2, a chain 3 is sleeved between the two corresponding front and rear sprockets, a transmission rod 4 is coaxially fixedly connected between the two sprockets located in the front, and a first motor 5 for driving the sprocket to rotate is fixedly installed on a U-shaped block 2 located in the front, and a moving seat 6 is fixedly connected to the upper ends of the two chains 3, and the two moving seats 6 are n-shaped and are in rolling contact with the upper end of the processing table 1. The first motor 5 can drive the two chains 3 to rotate synchronously at the same time through the setting of the transmission rod 4, and then drive the two moving seats 6 to move synchronously on the processing table 1.

[0018] A clamping mechanism is provided on the processing table 1, and the clamping mechanism includes a V-shaped mounting plate 7 fixedly connected to the upper ends of the two moving seats 6, and two rectangular boxes 8 symmetrical and perpendicular to each other are fixedly connected to the upper end of the mounting plate 7. Moving grooves 9 are provided in the two rectangular boxes 8, and the two moving grooves 9 are perpendicular to each other. A first two-way threaded rod 12 is rotatably connected between the front and rear inner walls of the two moving grooves 9, and two spaced moving bars 10 are slidably connected in the two rectangular boxes 8. The lower end of each moving bar 10 extends into the moving groove 9 and is threadedly connected to the corresponding first two-way threaded rod 12. A clamping column 11 is rotatably connected to the upper end of each moving bar 10. The four clamping columns 11 located in the same rectangular box 8 are distributed in a rectangular shape. When the first two-way threaded rod 12 rotates, the two moving bars 10 located in the same rectangular box 8 can move relatively, thereby driving the upper clamping column 11 to clamp the side plate of the bus duct. Pad rollers 18 are provided on the front and rear side walls of the two rectangular boxes 8. The pad rollers 18 are used to support the side panels placed on the rectangular boxes 8. When the two side panels are placed on the corresponding rectangular boxes 8 at the same time, the two side panels can remain in a vertical state. Then, it is only necessary to cut the required splicing angles of the two side panels in advance, and the alignment work can be completed directly on the two rectangular boxes 8.

[0019] A rotating disk 13 that passes through the mounting plate 7 is rotatably connected on the mounting plate 7 and between the two rectangular boxes 8. A bevel gear disk 14 is coaxially fixedly connected to the upper end of the rotating disk 13. Two first bidirectional threaded rods 12 are coaxially fixedly connected to driving rods 15 at opposite ends. The two driving rods 15 extend to the top of the bevel gear disk 14 at one end away from the first bidirectional threaded rod 12 and are fixedly sleeved with a bevel gear 16. The two bevel gears 16 are vertically meshed with the bevel gear disk 14. A rocking rod 17 is fixedly connected to the center position of the upper end of the bevel gear disk 14. The bevel gear disk 14 can be manually rotated by the rocking rod 17, and then the two driving rods 15 can rotate synchronously under the transmission of the bevel gear 16, so that the two first bidirectional threaded rods 12 rotate at the same time, thereby controlling the clamping columns 11 on the two rectangular boxes 8 to perform equal clamping work at the same time.

[0020] Specifically, the staff only needs to shake the rocker 17 to easily place the two side panels to be welded in the corresponding rectangular box 8 for clamping and limiting, so that the two can only move along the right angle direction to ensure the vertical state of the two side panels.

[0021] The clamping mechanism can be driven to move forward and backward on the processing table 1 by the moving mechanism, so that the side plate can be conveniently moved to the welding position after the side plate is clamped.

[0022] A brake grinding wheel 35 is coaxially fixedly connected to the lower end of the rotating disk 13. The outer peripheral surface of the brake grinding wheel 35 is a frosted surface, which has a good braking effect. An auxiliary limiting mechanism is provided at the upper end of the processing table 1 and below the brake grinding wheel 35. The auxiliary limiting mechanism includes four first vertical plates 36 fixedly connected to the upper end of the processing table 1 at intervals. The two first vertical plates 36 located on the inner side are respectively fixedly connected to the two first vertical plates 36 on the outer side with a sliding rod 37. The two sliding rods 37 are slidably sleeved with a first set of blocks 38. The upper ends of the two first sets of blocks 38 are fixedly connected with an arc-shaped brake clamp 39. The inner wall of the brake clamp 39 is made of rubber material. The two brake clamps 39 are arranged opposite to each other and are respectively located on both sides of the brake grinding wheel 35. The upper end of the processing table 1 is fixedly connected to two second vertical plates 40 arranged at an interval front and back. A second two-way threaded rod 41 is connected to the two second vertical plates 40 for common rotation. The second two-way threaded rod 41 runs through and is arranged between the two first vertical plates 36 located in the middle. Two second sets of blocks 42 arranged front and back are threadedly sleeved on the second two-way threaded rod 41. The two second sets of blocks 42 are connected to the two first sets of blocks 38 for common rotation with connecting rods 43 on both sides. A fourth motor 44 for driving the second two-way threaded rod 41 to rotate is fixedly installed on the second vertical plate 40 located in the front. When the fourth motor 44 drives the second two-way threaded rod 41 to rotate, it can drive the two second sets of blocks 42 to move relative to each other. In the relative movement state, under the connection action of the four connecting rods 43, the two first sets of blocks 38 also move relative to each other along the slide rod 37, thereby driving the two brake clamps 39 to move relative to each other.

[0023] Specifically, when the clamping mechanism moves the side plate to be welded to the welding position, the brake grinding wheel 35 is located between the two brake clamps 39, and then driven by the fourth motor 44, the two brake clamps 39 can be controlled to clamp the brake grinding wheel 35, so that the brake grinding wheel 35 cannot rotate, thereby achieving the purpose of braking the rotating disk 13 and the bevel gear disk 14, ensuring that the clamping column 11 will not loosen, thereby ensuring the clamping effect.

[0024] Two limiting slides 30 are provided at the upper end of the processing table 1. The two limiting slides 30 are in an eight-shaped shape and are arranged perpendicular to each other. End blocks are fixedly connected to the lower end of the processing table 1 and at the front and rear positions of the limiting slides 30. A second threaded rod 31 is rotatably connected between the two corresponding end blocks at the front and rear. The second threaded rod 31 is arranged parallel to the limiting slide 30. The end blocks located in the front are fixedly installed with a third motor 33 that drives the second threaded rod 31 to rotate. A T-plate 32 is vertically penetrated and slidably connected in the two limiting slides 30. The lower end of the T-plate 32 is connected to the second threaded rod 31. The rod 31 is threadedly connected, and a push plate 34 is fixedly connected to the upper end of the T-plate 32. The two push plates 34 are symmetrical and vertically arranged. After the side panels are clamped and moved to the welding position, the two push plates 34 are located at the rear ends of the two side panels and are arranged parallel to the rear ends of the side panels. At this time, the two second threaded rods 31 can be driven to rotate by two third motors 33 to control the movement of the corresponding push plates 34, thereby pushing the two side panels to move along the right angle line until the welding ends of the two are in close contact and maintained, so that the two side panels cannot move, and a stable state to be welded is achieved.

[0025] A slag drop opening 19 is provided at the rear end of the processing table 1 to facilitate the collection of solder for welding. A welding mechanism is provided at the upper end of the processing table 1 and above the slag drop opening 19. The welding mechanism includes two support plates 20 fixedly connected to the upper end of the processing table 1 and located on both sides of the slag drop opening 19. A top plate 21 is fixedly connected to the upper ends of the two support plates 20. A movable opening is longitudinally provided at the center position of the upper end of the top plate 21. End plates 22 are fixedly connected to the upper end of the top plate 21 and in front and behind the movable opening. A first threaded rod 24 and a limit rod 23 arranged at intervals on the left and right are provided between the two end plates 22. The first threaded rod 24 is rotatably connected to the two end plates 22. The limit rod 23 is fixedly connected to the two end plates 22. A movable plate 26 is sleeved on the first threaded rod 24 and the limit rod 23. The movable plate 26 is threadedly connected to the first threaded rod 24 and slidably connected to the limit rod 23. A second motor 25 for driving the first threaded rod 24 to rotate is fixedly installed on the end plate 22 located on the rear side, and a telescopic cylinder 27 is fixedly installed on the upper end of the movable plate 26. The telescopic end of the telescopic cylinder 27 passes through the movable plate 26 and the movable port and is fixedly installed with a rotating cylinder 28. An electric welding head 29 is fixedly installed on the rotating end of the rotating cylinder 28. The welding point position of the electric welding head 29 is located on the symmetry axis of the two rectangular boxes 8.

[0026] Specifically, after the two side panels are in the waiting-for-welding state, the welding lines of the two side panels are just located on the symmetry axes of the two rectangular boxes 8. Then, it is only necessary to control the forward and backward movement of the welding head 29 through the second motor 25, the up and down movement of the welding head 29 through the telescopic cylinder 27, and the flipping of the welding head 29 through the rotating cylinder 28, so as to complete the effective welding work on the right-angle welding points of the side panels.

[0027] After the welding is completed, it is only necessary to release the brake on the brake grinding wheel 35 through the fourth motor 44, and then use the moving mechanism to move the clamping mechanism to the front of the processing table 1, and then the shaking rod 17 can be shaken to remove the welded right-angle side panel, so as to carry out the welding work of the next right-angle side panel. The welding process is simple and has a high degree of automation, which ensures the production efficiency of the bus duct.

[0028] 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, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
