Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically a positioning tooling for assembling a single transformer chamber cabinet. Background Technology

[0002] In power systems, single transformer cabinets (such as GGD, GCS, and MNS models) typically consist of a base, side panels, top panel, door panel, brackets, and internal electrical components. Their manufacturing process requires frame welding or bolting, and the assembly process demands high dimensional accuracy and positional consistency between components to ensure smooth subsequent installation and other procedures.

[0003] Currently, cabinet assembly often uses simple support frames with manual clamps, which is prone to errors and can lead to problems such as cabinet frame distortion. In addition, bolt pressure plates are often used, which need to be tightened one by one, making the operation cumbersome and labor-intensive. Uneven clamping force can also cause structural deformation. Therefore, we propose a positioning fixture for single transformer room cabinet assembly. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a single transformer room cabinet assembly and positioning fixture, comprising a base, cabinets fixedly connected to the upper ends of both sides of the base, an operating table fixedly connected to the lower end between the two cabinets, a lifting platform slidably connected to the upper end between the two cabinets, a double-acting screw rotatably connected inside the operating table and the lifting platform, positioning platforms slidably connected to the lower ends of the lifting platform on both sides, and the outer periphery of one of the double-acting screws is threadedly connected to the positioning platform, a limit plate slidably connected inside the two positioning platforms, a rack fixedly connected to one side of the limit plate, a spur gear meshing with the upper end of the rack, and a worm gear coaxially fixedly connected to one side of the spur gear.

[0006] As a preferred embodiment of this utility model, the lower end of the worm gear is connected to a worm, a servo motor is fixedly installed on the outer periphery of the positioning table, and the output end of the servo motor passes through the positioning table and is connected to the worm through a coupling.

A connecting column is fixedly connected to the upper end of one of the bevel gears, and a sliding groove is opened on the outer periphery of the upper end of the connecting column. The interior of the other bevel gear is slidably connected to the sliding groove.

[0009] As a preferred technical solution of this utility model, both sides of the upper end of the operating table are slidably connected to movable seats, and the lower end of the movable seats is threadedly connected to one of the bidirectional lead screws. A micro motor is fixedly installed on the outer side of one end of each of the two movable seats, and the output ends of the two micro motors are connected to bidirectional threaded rods through a coupling.

[0012] The beneficial effects of this utility model are:

[0013] 1. This single transformer cabinet assembly and positioning fixture uses a worm gear transmission mechanism driven by a servo motor within the positioning table to rotate a spur gear, which in turn controls the movement of the limit plate via a rack and pinion.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-5 As shown, this utility model discloses a single transformer room cabinet assembly and positioning fixture, including a base 1. Cabinets 2 are fixedly connected to the upper ends of both sides of the base 1. An operating table 3 is fixedly connected to the lower end between the two cabinets 2. A lifting platform 4 is slidably connected to the upper end between the two cabinets 2. Both the operating table 3 and the lifting platform 4 are rotatably connected to a double-acting screw 5. Positioning platforms 6 are slidably connected to both sides of the lower end of the lifting platform 4, and the outer periphery of one of the double-acting screws 5 is threadedly connected to the positioning platform 6. Limiting plates 7 are slidably connected inside the two positioning platforms 6. A rack 8 is fixedly connected to one side of the limiting plate 7. A spur gear 9 is meshed with the upper end of the rack 8. A worm gear 10 is coaxially fixedly connected to one side of the spur gear 9.

[0025] The lower end of the worm gear 10 is connected to the worm 11. A servo motor 12 is fixedly installed on the outer periphery of the positioning table 6. The output end of the servo motor 12 passes through the positioning table 6 and is connected to the worm 11 via a coupling. When the servo motor 12 is started, it drives the worm 11 to rotate, which in turn drives the worm gear 10 and the spur gear 9 to rotate. This causes the rack 8 to move the limit plate 7, thereby achieving automatic limiting and release of the top of the cabinet side panel placed on the operating table 3.

[0026] Hydraulic rods 13 are fixedly installed inside both cabinets 2. The output end of the hydraulic rods 13 is fixedly connected to the lifting platform 4 through the connecting block 14. A geared motor 15 is fixedly installed on the lower outer side of the cabinet 2. The output end of the geared motor 15 is connected to one of the two-way lead screws 5 through the coupling. By synchronously controlling the extension and retraction stroke of the hydraulic rods 13 on both sides, the lifting platform 4 can be raised and lowered smoothly, and its working height can be adjusted to facilitate the fixing of the top of the cabinet side panels of different heights.

[0027] Among them, bevel gears 16 are fixedly connected to one end of each of the two bidirectional lead screws 5, and bevel gears 17 are meshed with the outer periphery of each of the two bevel gears 16. A connecting column 18 is fixedly connected to the upper end of one of the bevel gears 17. A sliding groove 19 is opened on the outer periphery of the upper end of the connecting column 18, and the interior of the other bevel gear 17 is slidably connected to the sliding groove 19. Through the sliding engagement of the sliding groove 19 and the bevel gear 17, a sliding synchronous transmission structure is formed, so that the bevel gear 17 can maintain power transmission while moving up and down within the range of the upper end of the connecting column 18, ensuring that the bidirectional lead screws 5 in the operating table 3 and the lifting platform 4 can still operate synchronously during the movement of the lifting platform 4.

[0028] The upper sides of the operating table 3 are slidably connected to movable seats 20, and the lower end of the movable seats 20 is threadedly connected to one of the bidirectional lead screws 5. A micro motor 21 is fixedly installed on the outer side of one end of each of the two movable seats 20. The output ends of the two micro motors 21 are connected to bidirectional threaded rods 22 through a coupling. When the bidirectional lead screw 5 is rotated, the two movable seats 20 can move towards or away from each other along the operating table 3, which can limit the movement of cabinet side panels of different sizes.

[0029] Among them, the two bidirectional threaded rods 22 are threaded to both ends of the outer periphery with positioning blocks 23, and the upper ends of the four positioning blocks 23 are provided with positioning angles 24. The four positioning angles 24 are L-shaped groove structures, which are used to snap onto the corners of the cabinet side panels, beams or mounting brackets to achieve quick positioning and clamping.

[0030] Both cabinets 2 have suction boxes 25 fixedly installed on their inner lower ends, and a suction pump 26 is fixedly installed on one side of the base 1. The output end of the suction pump 26 is fixedly connected to a filter box 27, and the output end of the filter box 27 is connected to the two suction boxes 25 through a connecting pipe 28. The filter box 27 has an activated carbon layer inside to purify dusty air. After the suction pump 26 is started, a negative pressure zone can be formed around the operating table 3, which can effectively collect metal dust and harmful fumes generated by welding, grinding and other processes, suck them in and filter them to maintain a clean working environment.

[0031] Working Principle: In use, first place the bottom frame or side panel of the single transformer cabinet to be assembled on the operating platform 3. Based on the cabinet dimensions, start the reduction motor 15, which, through the bevel gear 16, bevel gear 17, and connecting column 18 transmission system, drives the bidirectional lead screw 5 within the operating platform 3 and the lifting platform 4 to rotate synchronously, moving the two movable seats 20 to the appropriate position. Then, start the micro motor 21, driving the bidirectional threaded rod 22 to rotate, causing the positioning angle 24 on the positioning block 23 to clamp the corners of the cabinet components, achieving initial fixation. Then, start the hydraulic rods 13 on both sides, which, through the connecting block 14, drive the lifting platform 4 to descend until it contacts the top of the positioning platform 6. During the lifting process, the connecting column 18 slides along the slide groove 19, ensuring the continuous meshing of the bevel gear 17. This allows the bidirectional lead screw 5 inside the lifting platform 4 to still drive the two positioning platforms 6 for relative position adjustment. Next, the servo motor 12 is activated, driving the worm gear 11 and worm wheel 10 to rotate the spur gear 9. This causes the rack 8 to push the limit plate 7, thus securing the cabinet component inside the positioning platform 6. Combined with the positioning angle 24, this limits the cabinet component, preventing lateral displacement during assembly and ensuring positioning accuracy for assembly of the cabinet parts. Throughout the assembly process, the suction pump 26 is activated, continuously extracting dust from the work area through the suction box 25. It also collects metal dust and harmful fumes generated during welding, grinding, and other processes. After purification by the filter box 27, these are released into the atmosphere, protecting the health of operators and the workshop environment.
