Description

Technical Field

[0001] This utility model relates to the field of power equipment assembly technology, specifically a track-flow assembly tooling suitable for pole-mounted circuit breaker production lines. Background Technology

[0002] In the assembly line process of pole-mounted circuit breakers, traditional assembly tooling has many limitations:

[0003] 1. The distance between its two ends is fixed, which cannot flexibly adapt to the assembly requirements of different specifications of circuit breakers. Changing the tooling requires a lot of time, which seriously affects the production efficiency of the assembly line.

[0004] 2. The assembly tooling lacks insulation properties, making it impossible to conduct power frequency withstand voltage tests simultaneously during assembly. The assembled circuit breakers need to be transported to a dedicated testing area, increasing the number of procedures and costs.

[0005] 3. The circuit breaker's flipping operation mainly relies on manual labor, which is not only labor-intensive, but also makes it difficult to accurately control the flipping angle, which can easily cause damage to components or assembly deviations.

[0006] 4. Traditional tooling lacks a guiding structure to work with the assembly line track, resulting in poor stability when moving between workstations, which affects the assembly rhythm and accuracy. Summary of the Invention

[0007] To address the aforementioned technical problems, this utility model provides a track-based assembly tooling suitable for pole-mounted circuit breaker production lines. It features flexible telescopic and flipping functions, improving assembly efficiency and accuracy, reducing labor intensity, and adapting to the needs of production lines.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A track-based assembly fixture suitable for pole-mounted circuit breaker production lines includes a flexible telescopic base frame, an insulating support mechanism, a flipping mechanism, and a guide mechanism. The flexible telescopic base frame consists of channel steel on both sides and telescopic components connecting them, forming an adjustable-width telescopic structure. The insulating support mechanism includes two insulating support tubes, with their bottoms symmetrically fixed to the channel steel on both sides and the flipping mechanism fixed at the top. The flipping mechanism is used to fix the assembly components of the pole-mounted circuit breaker and perform a 360° flipping motion. The guide mechanism consists of four guide wheel assemblies with braking functions adapted to the production line track.

[0010] The telescopic component of the flexible telescopic base includes a square tube and an extension bend plate.

The speed reducer is fixedly located on the outer side of the top of the insulating support tube, and its output shaft is connected to the corresponding inner housing fixing plate via a key. The other housing fixing plate is rotatably connected to the inner side of the top of the insulating support tube on that side via a rotating shaft. The housing fixing plate and the housing fixing plate are bolted to the mounting holes of the pole-mounted circuit breaker mounting components. The speed reducer drives the housing fixing plate to flip the pole-mounted circuit breaker components and the housing fixing plate to rotate within a 360° range.

[0012] The bottom and top of the two insulating support tubes of the insulating support mechanism are respectively provided with fixing boxes. The fixing box at the top is provided with bearings, which are used to install the output shaft of the reducer and the rotating shaft connected to the housing fixing plate.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0024] like Figure 1-3 As shown, this assembly tooling suitable for the production line of pole-mounted circuit breakers includes a flexible telescopic base frame 1, an insulating support mechanism 2, a flipping mechanism 3, and a guide mechanism 4. The flexible telescopic base frame 1 consists of channel steels 11 on both sides and telescopic components connecting the two sides, forming a telescopic structure with adjustable width. The insulating support mechanism 2 includes two insulating support tubes 21, the bottoms of which are symmetrically fixed on the channel steels 11 on both sides, and the flipping mechanism 3 is fixedly installed on the top. The flipping mechanism 3 is used to fix the assembly components of the pole-mounted circuit breaker and perform a 360° flipping action. The guide mechanism 4 is configured as four guide wheel assemblies with braking function adapted to the production line track.

[0025] In a preferred embodiment, the telescopic component of the flexible telescopic base frame 1 includes a square tube 12 and an extension bending plate 13. The square tubes 12 are fixedly installed at the same position on the inner side of the channel steel 11 on both sides. The extension bending plate 13 is provided with a long slot 131. The two square tubes 12 and the extension bending plate 13 are fixedly connected by bolts provided in the long slot 131 and the connection position can be adjusted to achieve flexible telescopic movement.

[0026] The flexible telescopic base frame 1 uses channel steel 11 of model 10# Q235B, which has sufficient strength and rigidity to withstand various loads generated during assembly. The square tube 12 is made of 40×4 equilateral square tube Q235B, and is fixedly connected to the channel steel 11 by welding. The connection should be firm and reliable to ensure that it will not loosen during use. The square tubes 12 at both ends are connected to the extension bends 13 by long slot mounting bolts. The length of the long slot holes 131 on the extension bends 13 is determined according to the required telescopic range, specifically set to 350mm-400mm. The long slot mounting bolts pass through the long slot holes 131 to connect the square tubes 12 and the extension bends 13 together. When it is necessary to adjust the distance between the two ends, loosen the long slot mounting bolts, push the extension bends 13 to move relative to the square tubes 12, and after adjusting to the appropriate position, tighten the long slot mounting bolts to fix the two, realizing flexible telescopic adjustment of the distance between the two ends to adapt to different specifications of pole-mounted circuit breakers.

[0027] In a preferred embodiment, the flipping mechanism 3 includes a speed reducer 31 and two housing fixing plates 32. The speed reducer 31 and one housing fixing plate 321 are disposed on both sides of the top of one insulating support tube 211 of the insulating support mechanism 2. The speed reducer 31 is fixedly disposed on the outer side of the top of the insulating support tube 211, and its output shaft is connected to the corresponding inner housing fixing plate 321 by a key. The other housing fixing plate 322 is rotatably connected to the inner side of the top of the insulating support tube 212 on that side by a rotating shaft. The housing fixing plate 321 and the housing fixing plate 322 are fixedly connected to the mounting holes of the pole-mounted circuit breaker mounting components by bolts. The speed reducer 31 drives the housing fixing plate 321 to rotate the pole-mounted circuit breaker components and the housing fixing plate 322 within a 360° range.

[0028] The reducer 31 of the flipping mechanism is an NRV075, with a handwheel on the input shaft. It has a suitable reduction ratio and output torque to meet the flipping requirements of the circuit breaker components. The reducer 31 is bolted to the reducer pad 33, which is made of 6mm steel plate and is fixed to the corresponding mounting box 22. The output shaft of the reducer 31 is connected to the housing mounting plate 32 by a key connection to ensure reliable torque transmission between them. The housing mounting plate 32 can be bolted to the mounting holes of the pole-mounted circuit breaker 5. By starting the reducer 31, its output shaft drives the two housing mounting plates 32 and the pole-mounted circuit breaker 5 components to rotate together, realizing the flipping of the pole-mounted circuit breaker 5 components. The flipping angle can be adjusted within a 360° range to meet different assembly requirements.

[0029] In a preferred embodiment, the bottom and top of the two insulating support tubes 21 of the insulating support mechanism 2 are respectively provided with fixing boxes 22. Bearings 23 are installed inside the top fixing box 22, which are used to install the output shaft of the reducer 31 and the rotating shaft connected to the housing fixing plate 322. The bottom fixing box 22 is welded from steel plates and fixed to the channel steel 11 by welding. The insulating support tubes 21 and the bottom fixing box 22 are connected with bolts of M8×100 specification. During connection, the verticality of the insulating support tubes 21 should be ensured to avoid tilting. The top fixing box 22 is used to install the bearings 23, the housing fixing plate 32, and the reducer 31. The bearings 23 are F6006ZZ with flange seats to ensure the flexible rotation of the housing fixing plate 32.

[0030] As a preferred embodiment, in this case, the insulating support tube 21 of the insulating support mechanism 2 is made of epoxy fiberglass. Epoxy fiberglass tubes have excellent insulation and mechanical properties, and can meet the requirements of power frequency withstand voltage tests.

[0031] The guiding mechanism 4 has four guide wheel assemblies. The guide wheels are made of nylon and have a diameter of 30 mm. The guide wheels are mounted on the bottom of the channel steel 11 via axles and bearings, ensuring flexible rotation. The guide wheels are matched with the assembly line track, which is made of 10# Q235B channel steel, allowing the tooling to move smoothly along the track. Once the tooling reaches the designated workstation, it is fixed there for assembly operations, ensuring the stability of the assembly process.

[0032] When using this fixture to assemble a pole-mounted circuit breaker, first, adjust the distance between the two ends of the fixture according to the specifications of the circuit breaker to be assembled using a flexible telescopic structure (adjustable connection between square tube 11 and extension bend 13); then, fix the pole-mounted circuit breaker 5 to the housing fixing plate 1 321 and housing fixing plate 2 322 with bolts; during the assembly process, start the reducer 31 as needed to rotate the pole-mounted circuit breaker 5 to a suitable angle for assembly; if a power frequency withstand voltage test is required, it can be performed directly on this fixture, utilizing the insulation performance of the insulating support tube 21 to meet the test conditions; after the assembly operation of one station is completed, push the fixture along the track to the next station, fix the fixture upon arrival at the station, and continue the assembly operation.

[0033] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
