Abstract
Description
Technical Field
[0001] Specifically, it is a clamping and positioning structure for a pole-mounted circuit breaker tooling. Background Technology
[0002] In modern industrial assembly, the assembly process of pole-mounted circuit breakers commonly employs automated tooling carts for component transport and positioning. Typically, the base is mounted on a welding frame and then transported to a limit seat via a conveyor belt for clamping. However, the tooling cart contains electrical equipment such as motors and sensors, necessitating power supply to the base. Providing power to the base requires reliable positioning between the base and the welding frame; otherwise, poor power contact will occur. Therefore, designing a clamping and positioning structure for pole-mounted circuit breakers is essential. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clamping and positioning structure for pole-mounted circuit breaker tooling.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pole-mounted circuit breaker tooling clamping and positioning structure, including a welding frame, a base placed on the welding frame, and a limiting seat fixedly connected to the welding frame. The bottom of the welding frame is provided with a limiting component, which includes an execution component and a swing component. The execution component is used to drive the swing component to press against the limiting seat.

[0006] As a further improvement of this utility model, the clamping assembly includes a pair of pressure plates, a first rotating shaft and a second rotating shaft installed between the pair of pressure plates, the first rotating shaft being rotatably connected to a fixed base, and the second rotating shaft being rotatably connected to the output shaft of a cylinder.
[0007] As a further improvement of this utility model, the fixed base is provided with a through hole for mounting the first rotating shaft, and the first rotating shaft is installed in the through hole and rotates in cooperation with the through hole.
[0008] As a further improvement of this utility model, a bearing is provided inside the through hole, and the first rotating shaft is mounted on the bearing.
[0009] As a further improvement of this utility model, a bushing is provided on the second rotating shaft, and the bushing is sleeved on the second rotating shaft and fixedly connected to the output shaft of the cylinder.

[0011] As a further improvement of this utility model, the limiting component includes two half-shells, which are fixedly connected to the first rotating shaft by a locking member.
[0012] As a further improvement of this utility model, the limiting seat is provided with a position sensor for detecting that the base is pressed into place.
[0013] The beneficial effects of this utility model are that the cylinder is equipped with a driving component, and the welding frame is provided with an opening for the clamping component to extend. When the cylinder extends, the clamping component will extend out of the welding frame through the opening, and the base will be driven to the limit seat by the clamping component.

[0019] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.
[0020] Reference Figure 1-4As shown, a pole-mounted circuit breaker tooling clamping and positioning structure is disclosed. The structure includes a welding frame 1, a base 2 placed on the welding frame 1, and a limiting seat 3 fixedly connected to the welding frame 1. A limiting component is provided at the bottom of the welding frame 1. The limiting component includes an execution component and a swing component. The execution component is used to drive the swing component to press against the limiting seat 3. The swing component is driven by the execution component to abut against the base 2, so that the base 2 is pressed against the limiting seat 3.
[0021] In this embodiment, a limiting component is provided at the bottom of the welding frame 1. The limiting component includes an execution component and a swing component. The execution component is used to drive the swing component, and then the swing component drives the base 2 to move towards the limiting seat 3. Because the base 2 needs to be continuously powered, there are certain requirements for the accuracy of positioning. This setting can ensure that the base 2 can work continuously.
[0022] Preferably, the actuating component includes a cylinder seat 4 and a cylinder 5 fixedly connected to the welding frame 1, and the swinging component includes a fixed seat 6 fixedly connected to the welding frame 1 and a pressing component rotatably connected to the fixed seat 6. The output shaft of the cylinder 5 is rotatably connected to the pressing component, and the end of the cylinder 5 away from the output shaft is rotatably connected to the cylinder seat 4. The welding frame 1 is provided with an opening 7 for the pressing component to extend out. The pressing component is driven by the cylinder 5 to extend out of the opening 7 and press the base 2 onto the limiting seat 3.
[0023] In this embodiment, when not in operation, cylinder 5 is hidden at the bottom of welding frame 1, resulting in a better visual effect and a simpler overall appearance. When cylinder 5 is in operation, its output shaft extends to drive the clamping assembly to rotate. The clamping assembly also extends from the opening 7 on welding frame 1 as cylinder 5 moves. After extending from the opening 7, the clamping assembly drives the base 2 to press against the limit seat 3. The rotatable connection between the clamping assembly and the output shaft of cylinder 5 allows for better rotation of the clamping assembly, ensuring the correct angle of extension from the opening 7. Simultaneously, the end of cylinder 5 furthest from the output shaft is also rotatably connected to cylinder seat 4, further ensuring a better fit between the extension angle of cylinder 5 and the clamping assembly, thus guaranteeing the complete operation of the overall mechanism.
[0024] Preferably, the clamping assembly includes a pair of pressure plates 8, a first rotating shaft 9 and a second rotating shaft 10 installed between the pair of pressure plates 8, the first rotating shaft 9 being rotatably connected to the fixed base 6, and the second rotating shaft 10 being rotatably connected to the output shaft of the cylinder 5.
[0025] In this embodiment, the first rotating shaft 9 and the second rotating shaft 10 are both installed between the pair of pressure plates 8, and the position of the second rotating shaft 10 is further away from the fixed base 6 than that of the first rotating shaft 9. This arrangement allows the clamping assembly to adjust its rotation angle through the first rotating shaft 9 when rotating. The second rotating shaft 10 is rotatably connected to the output shaft of the cylinder 5, which allows the cylinder 5 to have more angles to adjust when it extends.
[0026] Preferably, the fixed base 6 is provided with a through hole for mounting the first rotating shaft 9, and the first rotating shaft 9 is mounted in the through hole and rotates in cooperation with the through hole.
[0027] In this embodiment, the first rotating shaft 9 passes through the fixed base 6 through the through hole and rotates with the through hole, which can strengthen the connection between the fixed base 6 and the first rotating shaft 9, making the overall mechanism more stable.
[0028] Furthermore, a bearing is provided inside the through hole, and the first rotating shaft 9 is mounted on the bearing.
[0029] In this embodiment, the first rotating shaft 9 can rotate through the bearing when it is in the through hole, which can have better rotational smoothness, reduce friction, and the number of bearings can be set to several.
[0030] Preferably, a bushing 11 is provided on the second rotating shaft 10, and the bushing 11 is sleeved on the second rotating shaft 10 and fixedly connected to the output shaft of the cylinder 5.
[0031] In this embodiment, the bushing can strengthen the connection between the second rotating shaft 10 and the output shaft of the cylinder 5, thereby improving the control force of the cylinder 5 on the second rotating shaft 10 during operation. The smoothness of the connection between the second rotating shaft 10 and the cylinder 5 also has a great influence on the final effect presented in this embodiment.
[0032] Preferably, the first rotating shaft 9 is provided with a pair of limiting components 12 to limit the axial movement of the first rotating shaft 9, and the pair of limiting components 12 are respectively installed on both sides of the fixed base 6.
[0033] In this embodiment, the limiting component 12 can limit the first rotating shaft 9, reducing the possibility of the first rotating shaft 9 moving in the axial direction and providing better stability.
[0034] Preferably, the limiting component 12 includes two half-shells, which are fixedly connected to the first rotating shaft 9 by a locking member.
[0035] In this embodiment, mounting holes are provided at the relative positions of the two half-shells. The locking member fixes the limiting member 12 to the first rotating shaft 9 through the mounting holes. At the same time, the arrangement of the two half-shells also facilitates the disassembly and installation of the limiting member 12.
[0036] Furthermore, the limiting seat 3 is equipped with a position sensor for detecting that the base 2 is pressed into place.
[0037] In this embodiment, the placement of a position sensor facilitates the detection of the accuracy of the base 2's positioning, thus simplifying subsequent operations. The above description is merely a preferred embodiment of this utility model, and the scope of protection of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.
