Description

Technical Field

[0001] This utility model relates to the field of mechanical design and manufacturing, and more specifically, it relates to a pole-mounted circuit breaker clamp with an adjustable rotation center of gravity. Background Technology

[0002] Currently, the main process flow of the pole-mounted circuit breaker production line is: shell loading, component assembly, product performance testing, sealing, and packaging. Among these, component assembly is the main production step. Each workstation needs to adjust the product to different postures when assembling different parts, highlighting the importance of the product's rotation. However, because the production line is compatible with many product models, each with a different center of gravity, the old pole-mounted circuit breaker rotating fixture only achieved shell loading. This had many inconveniences in actual production. For example, the old fixture was formed by cutting and bending thin metal sheets. Due to limitations in processing methods, the fixture's precision was rough, resulting in poor consistency (leading to the rotation axis not being horizontal). When the product was installed on the old fixture, the sides of the shell were obstructed, which was not conducive to the assembly of side components. After the fixture was bent, it could not be adjusted later, making it impossible to obtain the most suitable operating state for product rotation when changing product types.

[0003] For the reasons mentioned above, the question that this application addresses is how to obtain the optimal rotating operating state for different types of pole-mounted circuit breakers. Utility Model Content

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0034] Reference Figure 1-6 As shown, a pole-mounted circuit breaker clamp with adjustable rotation center of gravity includes a base 1, a support assembly 2, a drive assembly 3, and a rotation assembly 4.

[0035] The support assembly 2 is mounted on the base 1. The drive assembly 3 and the rotating assembly 4 are both mounted on the support assembly 2. The drive assembly 3 drives the rotating assembly 4, and the rotating assembly 4 is used to drive the pole-mounted circuit breaker to rotate.

[0036] Compared with existing technologies, most existing fixtures are formed by cutting and bending thin metal sheets. Due to the limitations of processing methods, the fixtures are rough in precision and have poor consistency (resulting in non-horizontal rotation axes). When changing products, it is impossible to obtain the most suitable operating state for product rotation. However, this utility model uses the cooperation of the support component 2, drive component 3 and rotation component 4 to drive the pole-mounted circuit breaker to rotate, so that the pole-mounted circuit breaker is in the most suitable operating state for rotation. Moreover, the fixture of this utility model can be precision machined by lathe and milling machine, solving the problem of dimensional consistency and the problem of rotational misalignment.

[0037] In the optimization, the drive component 3 includes a drive housing 31, and the rotation component 4 includes a connecting shaft 41;

[0038] The drive housing 31 is connected to the connecting shaft 41 and is used to drive the connecting shaft 41 to rotate.

[0039] The connecting shaft 41 is inserted into the drive housing 31, and the drive housing 31 is driven manually or by an external driver 32 to drive the connecting shaft 41 to rotate.

[0040] In the optimization process, driver component 3 also includes driver 32;

[0041] The driver 32 is connected to the drive housing 31, and the connecting shaft 41 is connected to the drive housing 31. The driver 32 is used to drive the connecting shaft 41 inside the drive housing 31 to rotate.

[0042] The connecting shaft 41 is inserted into the drive housing 31. The drive housing 31 is driven by the driver 32 to achieve the rotation of the connecting shaft 41. The connecting shaft 41 can rotate stably inside the drive housing 31, ensuring a smooth and efficient rotation process.

[0043] In the optimization, the rotating assembly 4 also includes a connecting seat 42, a moving column 43, and a moving part 44;

[0044] The connecting seat 42 is connected to the pole-mounted circuit breaker. One end of the movable column 43 is connected to the connecting seat 42, and the other end is connected to the movable member 44. The movable member 44 is connected to the connecting shaft 41 and is used to drive the connecting shaft 41 to move on the movable column 43.

[0045] The connecting shaft 41, the moving column 43, the moving part 44, and the connecting seat 42 cooperate to drive the pole-mounted circuit breaker to rotate, and also cooperate to drive the circuit breaker to move along the fixed trajectory of the moving column 43. The driver 32 drives the connecting shaft 41 to rotate, the rotation of the connecting shaft 41 drives the moving part 44 to rotate, the moving part 44 drives the moving column 43 to rotate, the moving column 43 is connected to the connecting seat 42, thereby driving the connecting seat 42 to rotate, and the connecting seat 42 is connected to the pole-mounted circuit breaker, thereby driving the pole-mounted circuit breaker to rotate. When installing different models of pole-mounted circuit breakers, by changing the position of the moving part 44 on the moving column 43, the height of the pole-mounted circuit breaker from the base 1 is changed, obtaining the most suitable working state for the rotation of the pole-mounted circuit breaker, making the rotation smoother. At the same time, the connecting seat 42, the moving column 43, the connecting shaft 41, and the moving part 44 make the overall structure simpler and the working space more sufficient.

[0046] In the optimization, the connecting seat 42 is provided with a sliding groove 421 and a first through hole 422;

[0047] The sliding groove 421 is used to connect with the pole-mounted circuit breaker, and the pole-mounted circuit breaker can move on the sliding groove 421. The first through hole 422 is used to connect with one end of the movable column 43.

[0048] The movable column 43 and the pole-mounted circuit breaker are fixed on both sides of the connecting seat 42. The connection part between the pole-mounted circuit breaker and the connecting seat 42 can be provided with a through groove corresponding to the sliding groove 421. The sliding groove 421 and the through groove of the pole-mounted circuit breaker correspond to each other and are fixedly connected by bolts and nuts. When it is necessary to replace different models of pole-mounted circuit breakers, the operator only needs to simply remove the bolts to easily carry out the replacement work, improving efficiency. The sliding groove 421 can be set as an ellipse. The pole-mounted circuit breaker can move on the fixed trajectory provided by the sliding groove 421, changing the position of the through groove on the connecting seat 42, thereby changing the position of the pole-mounted circuit breaker, so that the pole-mounted circuit breaker can obtain a suitable rotational working state. The end of the movable column 43 connected to the connecting seat 42 can be provided with threads. The first through hole 422 is provided with threads and is threaded to the threaded end of the movable column 43, and is used to reinforce the connection. Nuts can also be added to strengthen the connection between the movable column 43 and the connecting seat 42.

[0049] In the optimization, the moving part 44 includes a fastener 441, and the fastener 441 is provided with a second through hole 4411 and a third through hole 4412;

[0050] One end of the movable column 43 is inserted into the second through hole 4411. The second through hole 4411 is used for the movable part 44 to move along the fixed trajectory of the movable column 43. The third through hole 4412 is used to insert a bolt to adjust the inner diameter of the second through hole 4411.

[0051] After the movable column 43 is fixedly connected to the connecting seat 42, the movable part 44 is inserted into the movable column 43. The movable part 44 moves within the length range of the movable column 43. The movable part 44 and the connecting shaft 41 cooperate to drive the pole-mounted circuit breaker to move along the fixed trajectory of the movable column 43. Thus, by adjusting the height of the pole-mounted circuit breaker, the center of gravity of rotation is changed, avoiding the problem of the center of gravity moving away from the rotation axis and thus making rotation difficult when changing the model. The through hole makes the movable part 44 move more stably on the movable column 43, and is easy to install, allowing for the replacement of parts at any time. A bolt is inserted into the third through hole 4412. Through the cooperation of the bolt and nut, the inner diameter of the second through hole 4411 of the fastener 441 is changed. By decreasing or increasing the inner diameter of the second through hole 4411, the second through hole 4411 abuts against the movable column 43, restricting the movement of the movable part 43 and playing a role in tightening or loosening the movable part 43. Thus, through the cooperation of the bolt and nut, the position of the fastener 441 on the movable column 43 is changed.

[0052] During the optimization process, fastener 441 is equipped with a bending hole 4413;

[0053] The bent hole 4413 is adjacent to the first through hole 422 and facilitates bending of the fastener 441.

[0054] The bent hole 4413 is adjacent to the first through hole 422. When the second through hole 4411 is contracted, the bent hole 4413 provides space for the fastener 441 to bend inward, which facilitates the fastener 441 to better contract the second through hole 4411, thereby strengthening the connection between the fastener 441 and the moving post 43. When the second through hole 4411 is contracted, the bent hole 4413 can provide the fastener 441 with directional elastic deformation space, causing the fastener 441 body to undergo centripetal bending deformation. This deformation increases the contact pressure between the inner wall of the fastener 441 and the outer wall of the moving post 43, forming an interference fit reinforcement effect, effectively preventing axial displacement. At the same time, the stress release effect of the bent hole 4413 keeps the deformation process of the fastener 441 linear and elastic, avoiding the weakening of connection strength caused by local plastic deformation.

[0055] In the optimization, the moving part 44 also includes a fixing part 442, the fixing part 442 is provided with a connecting groove 4421, and the connecting shaft 41 is provided with a plug-in part 411;

[0056] One end of the connector 411 is connected to the connecting shaft 41, and the other end is inserted into the connecting groove 4421.

[0057] The connecting slot 4421 is set to be non-circular, for example... Figure 5The shape of the connecting groove 4421 is such that the plug-in 411 is set to correspond to the shape of the connecting groove 4421. Through the mutual cooperation of the connecting groove 4421 and the plug-in 411, the moving column 43 is driven to rotate. The non-circular design of the connecting groove 4421 increases the contact area, improves the rotational stability, reduces frictional loss, and extends the service life. The tight cooperation between the plug-in 411 and the connecting groove 4421 ensures the smoothness and accuracy of the rotation process.

[0058] In the optimization, the connecting shaft 41 is provided with a groove 412;

[0059] The groove 412 is connected to the driver 32 and is used to cooperate with each other to drive the connecting shaft 41 to rotate.

[0060] The driver 32 is provided with a protrusion that mates with the groove 412. When the driver 32 drives the connecting shaft 41 to rotate, the protrusion is inserted into the groove 412 to restrict the connecting shaft 41 from idling, thereby enabling the driver 32 to drive the connecting shaft 41 to rotate. The groove 412 and the protrusion mate to ensure the stability of the rotation process, avoid the ineffective rotation of the connecting shaft 41, enhance the transmission effect of the driving force, and improve the driving efficiency.

[0061] During the optimization process, a slide rail 11 is also installed on the base 1;

[0062] There are two support components 2 and two rotating components 4, forming a first clamp and a second clamp. The first clamp is installed on one side of the base 1, and the second clamp is installed on the slide rail 11.

[0063] The first clamp is equipped with a drive housing 31 and a rotating assembly 4. One side of the pole-mounted circuit breaker is connected to the rotating assembly 4 near the drive housing 31. The second clamp drives the rotating assembly 4 to move to the other side of the pole-mounted circuit breaker via a slide rail 11. The connection is made by fixing one side and moving and fixing it via the slide rail 11 on the other side, which facilitates worker operation and is suitable for pole-mounted circuit breakers of various models and sizes.

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 protection scope of this utility model.
