Description

Technical Field

[0001] The utility model discloses a turnover device, belonging to the technical field of distribution transformer coil assembly equipment, and specifically relates to a distribution transformer coil mold-closing turnover device. Background Art

[0002] Coil mold closing is a key step in the production of distribution transformers. It generally includes docking the transformer coil with the iron core, precisely positioning it through a mold, and then fixing and securing the coil to ensure its correct position in the transformer. This step aims to ensure the tight fit between the coil and the iron core, thereby improving the performance and stability of the transformer. During the mold-closing process, the coil is first placed on the iron core, and then a special mold-closing device is used to tightly dock the coil and the iron core. After mold closing, insulation treatment is carried out to prevent electrical short circuits. Finally, inspections are carried out to ensure that all connection points are firm and meet the specifications. This step is crucial for the electrical performance and mechanical stability of the transformer. After the distribution transformer completes mold closing, it needs to be turned over. The traditional turning work is carried out manually and transferred by a trolley, but this turning efficiency is low and the labor consumption is large. For large transformer coils, more than two people are required to complete the turning, so the efficiency is very low. At the same time, with the application of automated production lines, an automatic turning device is needed to realize the mold-closing turnover of distribution transformer coils.

One bracket is used for installing the left - right displacement assembly 4, and the telescopic rod of the flipping hydraulic cylinder 3 is fixedly connected to one bracket; the other bracket is used for placing the cart 8.

[0024] In one embodiment, as Figures 1 to 4 shown, the left - right displacement assembly 4 includes: a first motor 9; a driving gear 10 sleeved on the rotating shaft of the first motor 9 to rotate following the first motor 9; a rack 11 fixedly installed on the one bracket and meshing with the driving gear 10; a guide rail 12 fixedly installed inside the one bracket; two sliders 13 slidably installed on the guide rail 12.

[0025] In one embodiment, as Figures 1 to 4 shown, the front - back displacement assembly 5 includes: a first displacement frame 14 fixedly installed on one slider 13; a second displacement frame 15 fixedly installed on the other slider 13; a second motor 16 fixedly connected to the one bracket through a connecting plate; a driving sprocket 17 sleeved on the rotating shaft of the second motor 16 and rotating following the second motor 16; a driving shaft 18 with both ends installed at the bottom of the first displacement frame 14 and the second displacement frame 15 through roller bearings; a driven sprocket 191 sleeved on the driving shaft 18 and connected to the driving sprocket 17 through a chain; a first pulley 20 sleeved on both ends of the driving shaft 18 to rotate following the driving shaft 18; a second pulley 21 rotatably connected to both ends of the first displacement frame 14 and the second displacement frame 15 respectively; a belt rail 22 fixedly installed on the first displacement frame 14 and the second displacement frame 15 respectively; the first pulley 20 and the second pulley 21 are connected by a belt and the belt is located inside the belt rail 22.

[0026] In one embodiment, as Figures 1 to 4 shown, the first motor 9 is fixedly installed on the first displacement frame 14 through a connecting plate.

[0027] In one embodiment, as Figures 1 to 4As shown, tension wheels 23 are provided at the bottoms of the first displacement frame 14 and the second displacement frame 15, and the tension wheels 23 control the tension of the belt.

[0030] Working principle: When the present utility model is working (the distribution transformer coil can be transferred from the conveyor line to the cart 8, or from the cart 8 to the conveyor line, and the flipping is realized by the flipping device), first, the flipping hydraulic cylinder 3 works to rotate the flipping table 2 to one side. At the same time, the cart 8 is placed in the other bracket of the flipping table 2. Then, the flipping hydraulic cylinder 3 works to retract, so as to return the flipping table 2 to the base 1, and the shock-absorbing blocks 24 are used for shock absorption. At the same time, the left and right displacement assembly 4 works to adjust the position of the workpiece table 6. Thus, the first motor 9 rotates, driving the driving gear 10 to rotate. Then, the driving gear 10 meshes with the rack 11. Since the rack 11 is fixed on the base 1, the driving gear 10 rotates and moves on the rack 11, driving the first displacement frame 14 and the second displacement frame 15 to move left and right through the guide rail 12 and the slider 13, driving the workpiece table 6 to move left and right, and stopping after adjusting to the specified position. Then, the front and back displacement assembly 5 works, the second motor 16 rotates, drives the sprocket to rotate, and uses the transmission chain to drive the driven sprocket 191 to rotate, driving the driving shaft 18 to rotate. The driving shaft 18 drives the first belt wheels 20 at both ends to rotate, and drives the second belt wheels 21 of the first displacement frame 14 and the second displacement frame 15 to rotate through the belt, moving the workpiece table 6 to the side matching the conveyor line first. When the workpiece is placed on the workpiece table 6, the front and back displacement assembly 5 adjusts the position again, and at the same time, the left and right displacement assembly 4 cooperates with the cart 8 to dock the bottom of the workpiece with the cart 8. Then, the flipping hydraulic cylinder 3 works to drive the flipping table 2 to rotate, placing the workpiece on the cart 8, and the staff takes it away.

[0031] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description.

And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
