Description

Technical Field

[0001] The invention belongs to the technical field of transformer tooling equipment, and in particular relates to a rotary tooling table for assembling a transformer and a use method thereof. Background Art

[0002] With the continuous development of power equipment, transformer tooling equipment has been widely used in power systems. The application of these devices can save a lot of manpower and time costs in the assembly and manufacturing process of transformers. Rotary tooling table, also known as rotary workbench or rotary platform, is a device used to support and fix workpieces and make them perform precise rotational motion. It is widely used in mechanical processing, instrument assembly, automated production lines and other fields.

[0003] During the transformer assembly process, the transformer not only needs to be rotated, but also needs to be moved horizontally. However, the existing rotary tooling table does not have the function of horizontally moving large workpieces. Therefore, the current transformer assembly process has a low degree of automation, and most companies still use pure manual or semi-automatic methods. This method has the following problems: 1. Low efficiency: Enterprises usually use crane lifting to move transformers. After each assembly step is completed, the transformer body needs to be lifted and moved before the next assembly step can be carried out, which is inefficient.

[0004] 2. High labor intensity: Manual rotation and shifting are performed according to the needs of the assembly side, which requires continuous observation and intervention by the operator; 3. Poor safety: During manual lifting and auxiliary rotation, the lifting belt may swing or rotate slightly, resulting in deviation in the landing position when lowering. Therefore, some workers will manually push the transformer being hoisted to ensure accurate landing, which does not comply with safety regulations and greatly increases the safety risks of collision, falling and smashing; 4. Unable to meet the needs of mass production: The above-mentioned lifting and moving process requires the use of lifting equipment, and requires the cooperation of multiple workers such as lifting drivers and observation commanders, which increases the manpower requirements and cannot meet the needs of mass production.

The right end of the rotating shaft 1 32 passes through the roller bearing 2 35 and is rotatably mounted in the roller bearing 2 35. The retaining ring 1 27 and the retaining ring 2 37 are respectively fixedly mounted on the left and right ends of the rotating shaft 1 32 by bolts, and the retaining ring 2 37 limits the roller bearing 2 35.

The sleeve 2 31 passes through the circular hole of the roller support 1 22, and the two end surfaces of the sleeve 2 31 respectively abut against the roller bearing 1 36 and the roller 26, so as to limit the horizontal position of the roller 26 and prevent the roller 26 from contacting and rubbing with the roller support 1 36.

A sprocket keyway 38 and a roller keyway 39 are provided on the rotating shaft 1 32, and the rotating shaft 1 32 and the double-row sprocket 28 and the roller 26 are connected by nesting + keyway.

[0026] The rollers L3 and R3, as well as the rollers L4 and R4, are connected via the coupling 21 and the optical axis 20; the installation structure of the rollers L3, L4, R3 and R4 is similar to the installation structure of the rollers 26 at other positions above, except that the length of the second rotating shaft 40 is greater than the length of the first rotating shaft 32, the left end of the second rotating shaft 40 is connected to the coupling 21, and the outer peripheral sleeve of the second rotating shaft 40 between the double-row sprocket 28 and the coupling 21 is provided with a shaft sleeve 41, which is used for horizontal position limiting.

After the motor seat adjusting bolt 45 is rotated, it can push against the reinforcing rib on one side of the motor seat 14, which can not only fine-tune the position of the motor seat 14, but also rotate the motor seat adjusting bolt 45 after the chain is installed to further tighten the chain and increase the stability of the chain transmission.

Embodiment 2

[0029] The method for using a rotary tooling table for assembling a transformer according to the first embodiment comprises the following steps: ① Place the transformer casing to be assembled on the pallet, and use the lifting mechanism to place the transformer casing together with the pallet on the rotating workbench.

[0030] ② The worker starts assembly. When the transformer housing needs to be rotated during assembly, the rotary drive motor 5 is started through the control panel, and the rotary drive motor 5 drives the upper surface of the rotary bearing 7 to rotate, and the rotary bearing 7 drives the roller conveyor 1 to rotate. When the transformer housing needs to be moved horizontally, the roller motor 42 is started through the control panel, and the roller motor 42 drives the roller 26 to rotate, so that the tray moves slightly in the horizontal direction.

[0031] ③After completing the transformer assembly, use the lifting mechanism to transport the pallet and the finished transformer away.

[0032] like Fig.11 As shown, the process of the roller motor 42 driving the roller 26 to rotate is as follows: The roller motor 42 drives the roller reducer 43 to rotate, and the rotating shaft of the roller reducer 43 drives the driving sprocket 44 to rotate. When the driving sprocket 44 rotates, it drives the roller R4 to rotate through the chain and the double-row sprocket 28, and the roller R4 drives the roller R5 to rotate through the chain and the double-row sprocket 28, and the roller R5 drives the roller R6 to rotate through the chain and the double-row sprocket 28. At the same time, the roller R4 and the roller L4 are linked by the coupling 21-optical axis 20-coupling 21, and the roller L4 drives the roller L5 to rotate through the chain and the double-row sprocket 28, and the roller L5 drives the roller L6 to rotate through the chain and the double-row sprocket 28, and the roller L4 drives the roller L3 to rotate through the chain and the double-row sprocket 28, and the roller L3 drives the roller L2 to rotate through the chain and the double-row sprocket 28, and the roller L2 drives the roller L1 to rotate through the chain and the double-row sprocket 28. At the same time, the roller L3 and the roller R3 are linked through the coupling 21-optical axis 20-coupling 21. The roller R3 drives the roller R2 to rotate through the chain and the double-row sprocket 28, and the roller R2 drives the roller R1 to rotate through the chain and the double-row sprocket 28.

[0033] The usual design for synchronously driving multiple sprockets is to set the drive motor at one end and connect the sprockets in series in one direction. Different from the commonly used technical solution of six rollers 26 connected in series in sequence and couplings 21 and optical axes 20 are set between the left and right, the present invention only needs to use two couplings 21 and optical axes 20, and has a simple structure; the transmission path is optimized. From the perspective of transmission efficiency, the present invention places the roller motor 42 in the middle, which can reduce the distance from the drive end to the farthest terminal, reduce transmission loss, and drive products with heavier weight.

[0034] In the embodiments of the present invention, technical features that are not described in detail are all existing technologies or conventional technical means and will not be described in detail here.

[0035] Finally, it should be noted that the above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them, and the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that any technician familiar with the technical field can modify the technical solutions recorded in the above embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be covered within the protection scope of the present invention.
