Abstract
Description
Technical Field
[0001] This application relates to the field of circuit breaker assembly technology, and in particular to a circuit breaker assembly fixture. Background Technology
[0002] As a critical closing, load-bearing, and breaking device in a power system, the assembly quality of a circuit breaker directly determines its operational reliability. During manufacturing, a vertical assembly process is commonly used to facilitate the precise installation and commissioning of internal components (such as the arc-extinguishing chamber and operating mechanism). After the main assembly is completed, the circuit breaker needs to be flipped from its vertical position to a horizontal position for easy transport or storage.
[0003] Currently, the main method to achieve this posture conversion still relies on hoisting and flipping operations. Specifically, the operation process is usually as follows: using a workshop crane or large hoisting equipment, the circuit breaker in an upright position is lifted away from the assembly station, and then manually pulled by the guy ropes or operating equipment, the circuit breaker is slowly rotated in the air and finally placed smoothly on a horizontal storage rack or conveyor.
[0004] However, this traditional hoisting and flipping method has obvious drawbacks. The process must rely on lifting equipment, requires high skills from operators, and the circuit breaker is prone to shaking, bumping, or even falling during hoisting, which poses a risk of damaging the product's outer shell and internal components. At the same time, the operation requires the cooperation of multiple people, with many steps and complex coordination, which makes the flipping process time-consuming and labor-intensive, resulting in low flipping efficiency of existing circuit breakers.

When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0049] It should be noted that the directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0051] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, and a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.
[0052] As a critical closing, load-bearing, and breaking device in a power system, the assembly quality of a circuit breaker directly determines its operational reliability. During manufacturing, a vertical assembly process is commonly used to facilitate the precise installation and commissioning of internal components (such as the arc-extinguishing chamber and operating mechanism). After the main assembly is completed, the circuit breaker needs to be flipped from its vertical position to a horizontal position for easy transport or storage.
[0053] Currently, the main method to achieve this posture conversion still relies on hoisting and flipping operations. Specifically, the operation process is usually as follows: using a workshop crane or large hoisting equipment, the circuit breaker in an upright position is lifted away from the assembly station, and then manually pulled by the guy ropes or operating equipment, the circuit breaker is slowly rotated in the air and finally placed smoothly on a horizontal storage rack or conveyor.
[0054] However, this traditional hoisting and flipping method has obvious drawbacks. The process must rely on lifting equipment, requires high skills from operators, and the circuit breaker is prone to shaking, bumping, or even falling during hoisting, which poses a risk of damaging the product's outer shell and internal components. At the same time, the operation requires the cooperation of multiple people, with many steps and complex coordination, which makes the flipping process time-consuming and labor-intensive, resulting in low flipping efficiency of existing circuit breakers.
[0055] To address the technical problem of low switching efficiency in existing circuit breakers, this application proposes a circuit breaker assembly fixture, including a base and a drive device. A first support frame and a second support frame are spaced apart on the base. A first support plate is mounted on the first support frame, supporting the sidewalls of the circuit breaker when it is in a horizontal position. A movable plate is rotatably connected to the second support frame, and a first connecting portion is provided on the movable plate for detachable connection with the circuit breaker. The drive device is driven by the movable plate to switch between a first position and a second position around its rotation axis. The drive device is configured such that when the circuit breaker is connected to the movable plate via the first connecting portion, it drives the movable plate to the first position to bring the circuit breaker into a vertical position; and drives the movable plate to the second position to bring the circuit breaker into a horizontal position, with the end of the circuit breaker furthest from the movable plate supported on the first support plate.
[0056] During the initial assembly of the circuit breaker assembly fixture in this embodiment, the circuit breaker is first securely connected to the first connecting part on the movable plate using fasteners. Then, the drive device is activated, driving the movable plate to the first position (i.e., the vertical state), thus placing the circuit breaker in a vertical assembly state that facilitates the installation and debugging of internal components. When the assembly process is completed and the circuit breaker needs to be converted to a horizontal state for storage or transport, the drive device is activated again, driving the movable plate to rotate smoothly towards the first support frame. When the movable plate reaches the second position, the circuit breaker is precisely in a horizontal state, and its free end is stably supported on the first support plate. Subsequently, the connection can be released, and the horizontally positioned circuit breaker can be removed. The entire process is automatically completed by the drive device, smoothly and controllably, achieving an integrated and mechanized switch from vertical assembly to horizontal storage, eliminating the need for multiple people to coordinate hoisting operations, and greatly simplifying the process. Furthermore, because the attitude conversion can be completed in a short time through drive device control, the process is tightly connected, greatly improving the circuit breaker's turning efficiency, shortening the production cycle, and providing a guarantee for mass production.
[0057] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0059] In the embodiments of this application, reference is made to Figures 1 to 3 As shown, an embodiment of this application provides a circuit breaker assembly fixture, including a base 100 and a drive device 600.
[0060] The base 100 is provided with a first support frame 200 and a second support frame 300 at intervals.
[0061] A first support plate 400 is provided on the first support frame 200. The first support plate 400 is used to support the side wall of the circuit breaker 10 when it is in a horizontal state.
[0062] A movable plate 500 is rotatably connected to the second support frame 300. A first connecting part 510 is provided on the movable plate 500, which is used for detachable connection with the circuit breaker 10.
[0063] The drive unit 600 is connected to the movable plate 500 to drive the movable plate 500 to switch between a first position and a second position around its rotation axis.
[0064] The drive device 600 is configured to drive the movable plate 500 to a first position when the circuit breaker 10 is connected to the movable plate 500 via the first connecting part 510, so as to drive the circuit breaker 10 to a vertical position; and drive the movable plate 500 to a second position so as to drive the circuit breaker 10 to a horizontal position, and so that the end of the circuit breaker 10 away from the movable plate 500 is supported on the first support plate 400.
[0065] In the circuit breaker assembly fixture of this embodiment, the base 100 serves as the basic support component of the entire fixture and can be welded from structural steel, possessing sufficient structural strength and stability. A first support frame 200 and a second support frame 300 are fixedly installed at intervals along the length direction on the upper surface of the base 100.
[0066] The upper end of the second support frame 300 is rotatably connected to a movable plate 500 via a rotating shaft. The movable plate 500 can be a rigid plate, with one end fixedly connected to the rotating shaft, allowing the movable plate 500 to rotate around the axis of the rotating shaft. A first connecting part 510 is provided on the movable plate 500, which is used to achieve a detachable connection with the circuit breaker 10.
[0067] Specifically, in this embodiment, the first connecting part 510 can be multiple threaded holes or through holes, which are secured and detachable by bolts engaging with pre-set connecting holes on the circuit breaker 10 housing. This connection method can prevent the circuit breaker 10 from shaking.
[0068] A first support plate 400 is fixedly installed at the upper end of the first support frame 200. The position of the first support plate 400 is configured such that when the movable plate 500 is rotated to bring the circuit breaker 10 on it to a horizontal position, the end of the circuit breaker 10 away from the movable plate 500 can be stably supported on the first support plate 400, thereby providing reliable auxiliary support after being flipped into place.
[0069] The drive unit 600 is connected to the movable plate 500 for driving its rotation around the axis. The drive unit 600 can be of various types, such as an electric actuator, hydraulic cylinder, or servo motor. The drive unit 600 can be controlled by an operator using simple control buttons, thus reducing reliance on operator skills, such as those of a crane operator.
[0070] The working process of the circuit breaker assembly fixture in this embodiment is as follows:
[0071] During initial assembly, the circuit breaker 10 is first securely connected to the first connecting part 510 on the movable plate 500 using fasteners. The drive device 600 is then activated to drive the movable plate 500 to the first position (i.e., the vertical state), thereby placing the circuit breaker 10 in a vertical assembly state that facilitates the installation and debugging of internal components.
[0072] When the assembly process is complete and the circuit breaker 10 needs to be converted to a horizontal position for storage or transfer, the drive unit 600 is restarted, driving the movable plate 500 to rotate smoothly towards the first support frame 200. When the movable plate 500 reaches the second position, the circuit breaker 10 is exactly in a horizontal position, and its free end is stably supported on the first support plate 400. Subsequently, the connection can be disconnected, and the horizontally positioned circuit breaker 10 can be removed. The entire process is automatically completed by the drive unit 600, smoothly and controllably, realizing an integrated and mechanized switch from vertical assembly to horizontal storage, eliminating the need for multiple people to coordinate hoisting operations, and greatly simplifying the process.
[0073] The circuit breaker assembly fixture in this embodiment uses the mechanical flipping of the movable plate 500 and the drive device 600 to ensure that the circuit breaker 10 is always under rigid connection and stable support during the attitude change process. This avoids the risk of equipment damage caused by shaking and collision in traditional hoisting, as well as the hidden danger of falling from height, thus ensuring the integrity of the product and the safety of personnel.
[0074] Furthermore, the circuit breaker assembly fixture in this embodiment can complete the attitude conversion in a short time under the control of the drive device 600, with close process connection, which greatly improves the turning efficiency of the circuit breaker 10, shortens the production cycle, and provides a guarantee for mass production.
[0075] Furthermore, the circuit breaker assembly fixtures in this application are simple and intuitive to operate, and can be operated by ordinary workers after simple training, reducing the requirements for professional skills. At the same time, it eliminates the absolute dependence on large-scale special lifting equipment such as workshop cranes, reducing equipment occupancy costs and scheduling complexity.
[0076] Furthermore, the drive unit 600 can precisely control the flipping angle and speed, ensuring that the circuit breaker 10 can smoothly and accurately reach the predetermined working position, avoiding the uncertainty in manual operation and improving the standardization and consistency of assembly operations.
[0077] In some embodiments, the base 100 includes a fixed plate 110 and a sliding plate 120. The fixed plate 110 is provided with a slide rail 111 extending along the length direction when the circuit breaker 10 is in a horizontal state. The sliding plate 120 is slidably connected to the slide rail 111. A first support frame 200 is disposed on the sliding plate 120, and a second support frame 300 is disposed on the fixed plate 110. The sliding plate 120 is configured to slide on the slide rail 111 to adjust the distance between the first support frame 200 and the second support frame 300.
[0078] In this embodiment, the fixing plate 110 can be cut and welded from high-strength alloy steel plate, and is rectangular in shape. It can be fixed to the workshop floor with expansion bolts to ensure the overall installation stability of the tooling and prevent the tooling from shifting during the adjustment of spacing or flipping. A slide rail 111 is machined on the fixing plate 110 along the length direction of the circuit breaker 10 when it is in a horizontal state. The slide rail 111 can adopt a dovetail groove structure or a rectangular guide rail groove, etc. The groove width is precisely matched with the size of the matching slider 430 of the sliding plate 120. The groove wall is ground to ensure smoothness and reduce sliding resistance.
[0079] The sliding plate 120 can be made of the same steel plate as the fixed plate 110. The sliding plate 120 is embedded in the slide rail 111 to achieve a sliding connection. The top surface of the sliding plate 120 can be detachably provided with a first support frame 200 by bolts. The connection strength meets the load requirements of supporting the horizontal circuit breaker 10.
[0080] Specifically, the fixed plate 110 has an opening, and slide rails 111 are formed on both sides of the opening. The two sides of the sliding plate 120 are slidably connected to the slide rails 111 on both sides of the opening.
[0081] Furthermore, sliding wheels can be installed on both sides of the sliding plate 120 to make the sliding smoother and reduce sliding resistance.
[0082] To prevent the sliding plate 120 from shifting after adjustment, a locking element can be provided between the fixed plate 110 and the sliding plate 120. Specifically, it is a combination structure of locking bolts and positioning holes. The fixed plate 110 is machined with multiple positioning holes at even intervals along the extension direction of the slide rail 111. The sliding plate 120 is provided with threaded through holes at corresponding positions. When the sliding plate 120 is adjusted to the target position, the locking bolt is passed through the threaded through hole and screwed into the corresponding positioning hole to achieve rigid locking between the sliding plate 120 and the fixed plate 110. At the same time, the side wall of the slide rail 111 is engraved with length scales, and the sliding plate 120 is provided with indicator lines, which makes it easy for operators to accurately read the adjustment distance and improve the adaptation efficiency.
[0083] The second support frame 300 can be fixed to the fixed plate 110 by welding or bolting.
[0084] When the model of the circuit breaker 10 to be assembled changes, and its length (i.e., the distance between the first connecting part 510 and the side wall that needs to be supported) changes, the operator can release the locking element (if present) and then push the sliding plate 120 or directly push the first support frame 200. The sliding plate 120 then moves the first support frame 200 on it closer to or further away from the second support frame 300 fixed on the fixed plate 110, thereby precisely adjusting the support distance between the two. When the circuit breaker 10 is adjusted to a suitable position so that it can be stably placed between the movable plate 500 and the first support plate 400, the position of the sliding plate 120 can be fixed by locking the locking element (if present), and then the operation can begin.
[0085] In this embodiment, the distance between the first support frame 200 and the second support frame 300 can be precisely adjusted steplessly or in steps through the cooperation of the sliding plate 120 and the slide rail 111. This means that the same tooling can easily adapt to circuit breaker 10 products of different lengths and specifications, avoiding the limitation of one machine for one use, significantly expanding the application range of the tooling, reducing the cost of repeatedly purchasing special tooling due to changes in product models, and eliminating the trouble of customizing different tooling for different specifications of circuit breakers 10. This achieves multi-purpose use and greatly improves the versatility and economy of the tooling.
[0086] Furthermore, the sliding structure operates smoothly and requires little effort, allowing operators to easily and intuitively adjust the spacing and quickly switch the tooling to the target working state. This effectively reduces the time spent changing tooling or using pads and other auxiliary adjustments, making the process connections smoother and thus improving overall assembly efficiency.
[0087] In another embodiment, a third support frame 700 is also provided on the base 100. The first support frame 200, the second support frame 300 and the third support frame 700 are arranged in sequence along the length direction when the circuit breaker 10 is in a horizontal state. A second support plate 800 is provided on the third support frame 700. A second connecting part 810 is provided on the second support plate 800. The second connecting part 810 is configured to be detachably connected to the movable plate 500 when the movable plate 500 is rotated to the first position, so as to lock the movable plate 500 in the first position.
[0088] In this embodiment, the base 100 serves as the basic platform for the entire tooling. In addition to the first support frame 200 and the second support frame 300, a third support frame 700 is also fixedly installed. The first support frame 200, the second support frame 300, and the third support frame 700 are arranged sequentially and at intervals along the length direction of the circuit breaker 10 when it is in a horizontal state; that is, the first support frame 200, the second support frame 300, and the third support frame 700 are arranged sequentially and at intervals along the length direction of the base 100. When the movable plate 500 rotates to the first position, the second connecting part 810 is detachably connected to the movable plate 500 to lock the movable plate 500 in the first position.
[0089] The third support frame 700, the second support plate 800, and the second connecting part 810 together constitute a locking mechanism for the movable plate 500, which provides rigid support when the movable plate 500 is rotated to the vertical position of the circuit breaker 10 (i.e., the first position) to prevent the movable plate 500 from swinging back unexpectedly.
[0090] Specifically, the third support frame 700 is fixed to the base 100 and is arranged sequentially with the first support frame 200 and the second support frame 300 along the length of the base 100 (i.e., the length of the circuit breaker 10 when it is placed horizontally). The height of the third support frame 700 matches that of the second support frame 300, ensuring that the second support plate 800 at its top can align with the corresponding part on the movable plate 500.
[0091] The third support frame 700 can be fixed to the base 100 by welding or bolting. Its material can be steel to ensure load-bearing stability.
[0092] The second support plate 800 is horizontally fixed to the top of the third support frame 700. Support slots, threaded holes or pin holes are provided on its surface to form the second connecting part 810.
[0093] The second connecting part 810 may take the form of a support slot, a pin mechanism, a bolt mechanism, a snap-fit structure, etc.
[0094] Specifically, for example, when a support slot is provided, a support slot can be provided on the upper surface of the second support plate 800. The support slot is used to engage and support the movable plate 500, thereby supporting and fixing the movable plate 500.
[0095] For example, a pin mechanism can be added, with a pin sleeve vertically installed on the second support plate 800, and a pin hole provided at the corresponding position on the movable plate 500. When the movable plate 500 rotates to the first position, the pin can be manually inserted to complete the locking.
[0096] For example, a bolt mechanism can be added, with a threaded fixing block on the second support plate 800, and the movable plate 500 can be tightened and fixed by tightening bolts.
[0097] For example, a snap-fit structure can be added, using a spring snap-fit that quickly engages with the groove of the movable plate 500, suitable for scenarios that require frequent switching of locking.
[0098] The specific engagement process between the movable plate 500 and the second connecting part 810 is as follows: when the drive device 600 pushes the movable plate 500 to rotate to the first position (circuit breaker 10 in vertical position), the mating hole at the end of the movable plate 500 aligns with the second connecting part 810. The operator then uses a pin to insert or a bolt to tighten, thus forming a rigid connection between the movable plate 500 and the third support frame 700.
[0099] In this embodiment, when the circuit breaker 10 is in a vertical position, the movable plate 500 is rigidly connected to the third support frame 700 through the second connecting part 810, which effectively counteracts the overturning moment generated by the weight of the circuit breaker 10, prevents the movable plate 500 from shifting due to external force or vibration, and avoids installation errors caused by workpiece shaking during assembly.
[0100] Furthermore, the locking mechanism eliminates the risk of accidental swing of the movable plate 500, protecting operators from impact injuries. For example, when tightening the circuit breaker bolts 10, a sudden loosening of the tooling could cause the component to slip off, but this design provides redundant protection through physical locking.
[0101] In another possible embodiment, the third support frame 700 includes at least one third telescopic rod 710, one end of which is fixedly connected to the base 100, and the other end of which is fixedly connected to the second support plate 800.
[0102] In this embodiment, the third support frame 700 adopts a height-adjustable telescopic rod structure to achieve flexible adjustment of the support height. The third support frame 700 mainly includes at least one third telescopic rod 710.
[0103] The third telescopic rod 710 is preferably a linear drive mechanism such as an electric push rod, hydraulic cylinder, or pneumatic cylinder. The bottom end (i.e., the fixed end) of the third telescopic rod 710 is firmly fixed to the base 100 by means of bolt connection or welding to ensure the stability of the support. The top end (i.e., the telescopic end) of the third telescopic rod 710 is fixedly connected to the bottom of the second support plate 800.
[0104] When the circuit breaker 10 is in a vertical assembly position driven by the drive device 600, the operator can control the third telescopic rod 710 to extend or retract according to the actual height of the specific model of circuit breaker 10. By extending or shortening the third telescopic rod 710, the second support plate 800 at its top can be raised or lowered, thereby precisely adjusting the height position of the second support plate 800 so that it can accurately and stably support the movable plate 500. After adjustment, the current height can be fixed by the self-locking function of the telescopic rod or by an additional mechanical locking device (such as a locking screw) to ensure the reliability of support during subsequent assembly.
[0105] This embodiment, through the stepless or stepped adjustment of the telescopic rod, can precisely match circuit breaker 10 products of different models and heights. This allows one set of tooling to meet the production needs of multiple product specifications, effectively reducing the cost of purchasing or modifying special tooling due to product changes, and is particularly suitable for flexible production modes of small batches and multiple varieties.
[0106] Furthermore, operators can easily and quickly adjust the support height using control buttons or handles without the need for auxiliary tools such as pads. This adjustment method saves time and effort, simplifies the production preparation process, and allows for faster switching of tooling between different assembly tasks, thus helping to improve overall assembly efficiency.
[0107] In some embodiments, reference is made to Figure 2 and Figure 4 As shown, the second support plate 800 includes a first sub-plate 820 and a second sub-plate 830. The first sub-plate 820 is connected to the base 100 through at least one third telescopic rod 710, and the second sub-plate 830 is connected to the base 100 through at least one third telescopic rod 710. A clearance gap 20 is provided between the first sub-plate 820 and the second sub-plate 830.
[0108] The clearance 20 is configured to avoid the pull rod of the circuit breaker 10 when the movable plate 500 drives the circuit breaker 10 to switch between a vertical and a horizontal state.
[0109] In this embodiment, the second support plate 800 adopts a split design, which is jointly composed of a first sub-plate 820 and a second sub-plate 830. The first sub-plate 820 and the second sub-plate 830 are arranged side by side at intervals in the width direction of the base 100, with a certain gap between them, thereby forming a clearance gap 20.
[0110] The first sub-plate 820 and the second sub-plate 830 are independent support units, and their bottoms are directly connected to the base 100 via at least one third telescopic rod 710. That is, the first sub-plate 820 and the second sub-plate 830 can be independently driven by a set of telescopic rods to achieve independent adjustment of their respective support heights, thereby better adapting to the position of the movable plate 500 and providing more stable support for the movable plate 500.
[0111] It should be noted that both the first sub-plate 820 and the second sub-plate 830 are provided with a second connecting part, and the second connecting part on the first sub-plate 820 and the second sub-plate 830 of the second sub-plate 830 together form the second connecting part 810.
[0112] When the movable plate 500 is driven by the drive device 600 to drive the circuit breaker 10 to rotate, the clearance 20 provides a dedicated movement channel for the pull rod (or other similar operating levers, linkage mechanisms, or other protruding parts) extending from the bottom of the circuit breaker 10 when switching between a vertical state for easy assembly and a horizontal state for easy storage.
[0113] The specific working process is as follows:
[0114] When the circuit breaker 10 is in the vertical assembly state, the second support plate 800 rises to an appropriate height, and its first sub-plate 820 and second sub-plate 830 are respectively supported on the two reliable parts on both sides of the bottom of the movable plate 500. At this time, the tie rod at the bottom of the circuit breaker 10 is exactly located within the clearance gap 20, and does not interfere with the first sub-plate 820 and the second sub-plate 830.
[0115] When the circuit breaker 10 needs to be tilted, the drive unit 600 starts working, and the movable plate 500 drives the circuit breaker 10 to rotate. During this process, the pull rod of the circuit breaker 10 swings accordingly. Due to the pre-set clearance 20, the pull rod will not collide or scrape with the first sub-plate 820 and the second sub-plate 830 on the movement trajectory, but will pass smoothly through the clearance 20, thereby ensuring the smoothness, stability and safety of the tilting action, and effectively preventing equipment damage or operation jamming caused by motion interference.
[0116] This application provides a dedicated and safe movement path for the lever by pre-setting a clearance 20, eliminating this risk and ensuring the smoothness and reliability of the entire attitude transition process, which is crucial for protecting the integrity of the circuit breaker 10 and its external mechanisms.
[0117] Furthermore, the split design, coupled with independent telescopic rod drive, allows the first sub-plate 820 and the second sub-plate 830 to be finely adjusted in height independently. This enables the fixture to not only adapt to movable plates 500 of different heights, but also to cope with uneven support surfaces that may exist at the bottom of the movable plate 500, resulting in a more uniform distribution of support force and a closer fit of support contact, greatly enhancing the fixture's adaptability to different models and specifications of circuit breakers 10.
[0118] In another embodiment, the first support frame 200 includes a first telescopic rod assembly 210 and a first rotating shaft 220. One end of the first telescopic rod assembly 210 is fixedly connected to the base 100, and the other end of the first telescopic rod assembly 210 is provided with a first bearing assembly 211. The first rotating shaft 220 is rotatably connected to the first bearing assembly 211, and the first support plate 400 is fixed on the first rotating shaft 220.
[0119] In this embodiment, the first support frame 200 is mainly composed of three parts: the first telescopic rod group 210, the first bearing group 211, and the first rotating shaft 220.
[0120] The first telescopic rod assembly 210 serves as the support column and height adjustment mechanism for the support frame. One end of it is securely fixed to the base 100 via bolts or welding. The first telescopic rod assembly 210 can employ an electric push rod, a hydraulic cylinder, or a scissor-type lifting mechanism. By controlling its extension and retraction, the entire upper structure of the support frame can be vertically raised and lowered, thereby flexibly adjusting the support height to accommodate circuit breakers 10 at different heights.
[0121] A first bearing assembly 211 is provided at the other end of the first telescopic rod assembly 210. This bearing assembly can be a self-aligning roller bearing or a mounted spherical roller bearing. These bearings have a certain self-aligning function, which can better adapt to installation errors and ensure smooth rotation. The first bearing assembly 211 is fixedly connected to the top end of the first telescopic rod assembly 210.
[0122] The first rotating shaft 220 passes through the inner ring of the first bearing assembly 211, achieving a smooth rotational connection. The axial direction of the first rotating shaft 220 is parallel to the width direction of the circuit breaker 10.
[0123] The first support plate 400 is fixedly installed on the first rotating shaft 220 by means of welding or flange connection, and the first support plate 400 can rotate together with the first rotating shaft 220.
[0124] When the circuit breaker 10 is driven to a horizontal position by the movable plate 500 and requires support, the operator first controls the first telescopic rod assembly 210 to extend or retract according to the actual height of the circuit breaker 10, raising or lowering the first support plate 400 to a height approximately flush with the support point on the side wall of the circuit breaker 10. Subsequently, the rotation angle of the first support plate 400 around the first rotating shaft 220 can be manually fine-tuned to ensure its support surface perfectly fits the side wall of the circuit breaker 10. For applications requiring precise control, a simple worm gear mechanism or linkage mechanism can be added, along with a handwheel for more precise angle adjustments. After adjustment, the position of the first rotating shaft 220 can be fixed using an additional locking device (such as a locking screw or pin) to prevent rotation during subsequent operations and ensure the reliability of the support.
[0125] In this embodiment, through independent fine-tuning of height and angle, the first support plate 400 can always fit optimally against the side wall of the circuit breaker 10, providing large-area, uniform, and stable support. This avoids the risk of the circuit breaker 10 swaying, tilting, or even slipping in a horizontal state due to support mismatch, and provides a safe and stable working platform for any subsequent operations (such as wiring and installing accessories) performed above the circuit breaker 10, effectively ensuring assembly accuracy and operator safety.
[0126] Different models and series of circuit breakers 10 may have variations in the height and profile angle of their side wall support points. This embodiment achieves stepless or stepped height adjustment via a telescopic rod assembly, combined with angle adjustment via a rotating shaft, allowing a single tooling set to easily adapt to various product specifications. This greatly improves the versatility of the tooling, reduces the cost of purchasing or modifying dedicated tooling due to product changes, and is particularly suitable for flexible production lines with multiple product types and small batches.
[0127] In some embodiments, reference is made to Figure 5 As shown, the first support plate 400 is recessed on one side facing the circuit breaker 10 to form an arc-shaped support recess 410, which is used to accommodate and support the side wall of the circuit breaker 10 in a horizontal state.
[0128] The first support plate 400 is provided with a plurality of sliding grooves 420, and the extending directions of each sliding groove 420 intersect at the center of the arc-shaped support recess 410.
[0129] A slider 430 is slidably connected inside the slide groove 420. An abutment rod 440 is provided on the slider 430, and the free end of the abutment rod 440 points to the center of the arc-shaped support recess 410.
[0130] The slider 430 is configured to adjust the depth of the free end of the abutment rod 440 extending into the arc-shaped support recess 410 by sliding along the slide groove 420, so that the abutment rod 440 fits against the side wall of the circuit breaker 10 to adapt to different specifications of the circuit breaker 10.
[0131] In this embodiment, the first support plate 400 can be made of steel plate, and its side facing the circuit breaker 10 is formed by pressing or cutting to create an arc-shaped support recess 410. The curvature of this recess is precisely calculated to match the side wall shape of the target series circuit breaker 10, providing initial, large-area wrapping support when the circuit breaker 10 is in a horizontal state, ensuring uniform stress distribution.
[0132] On the surface of the first support plate 400, multiple grooves 420 are provided. These grooves 420 can be linear guides or T-slot structures, and their extension directions all point to or intersect the theoretical center of the arc-shaped support recess 410. This radial layout is the key to achieving radial adjustment.
[0133] Each slide groove 420 is equipped with a slider 430, and the slider 430 and the slide groove 420 form a sliding pair. To achieve precise positioning and prevent loosening, a locking screw can be provided on the slider 430. After the slider 430 slides to the target position, tightening the locking screw will fix it in the slide groove 420.
[0134] An abutment rod 440 is fixed on each slider 430. The free end of the abutment rod 440, that is, the end away from the slider 430, points towards the central area of the arc-shaped support recess 410.
[0135] When adapting a new circuit breaker 10, the operator first places the circuit breaker 10 horizontally, allowing its sidewalls to fall into the arc-shaped support recess 410 of the first support plate 400. At this time, there may be gaps between the sidewalls of the circuit breaker 10 and the recess, or they may not fit completely due to size differences. Subsequently, the operator slides the sliders 430 in each groove 420 in sequence. The movement of the sliders 430 will cause the abutment rods 440 on them to move forward or backward along the radial direction of the groove 420, that is, change the depth of the abutment rods 440 extending into the arc-shaped support recess 410. When the free ends of all the abutment rods 440 are tightly fitted against the sidewalls of the circuit breaker 10, completely eliminating gaps, the locking screws on the sliders 430 can be tightened to fix the position. At this time, the circuit breaker 10 is firmly limited in a stable support system composed of macroscopic support provided by the arc-shaped support recess 410 and microscopic auxiliary clamping provided by multiple abutment rods 440.
[0136] Traditional support plates are often only compatible with a single type of circuit breaker 10. Changing products requires changing tooling or using pads, which is inefficient and poses safety hazards. This embodiment, through the design of a radially sliding abutment rod 440, achieves stepless or stepped adjustment of the support size. The same set of tooling can quickly and accurately adapt to a series of circuit breakers 10 with different widths and profiles, realizing multi-purpose functionality and significantly reducing tooling investment costs and changeover time. It is particularly suitable for flexible production lines with multiple varieties and small batches.
[0137] Multiple radially arranged abutment rods 440 can simultaneously apply balanced clamping force to the sidewalls of the circuit breaker 10 from different directions, effectively eliminating swaying and displacement of the workpiece during the support process. This provides an extremely stable and reliable working platform for any subsequent precision operations performed on the circuit breaker 10, greatly improving assembly accuracy and product quality consistency, while reducing safety risks caused by workpiece instability.
[0138] In other embodiments, refer to Figure 5 As shown, the free end of the abutment rod 440 is provided with an arc-shaped abutment plate 450. The arc of the arc-shaped abutment plate 450 is adapted to the arc of the arc-shaped support recess 410 and fits the contour of the side wall of the circuit breaker 10.
[0139] In this embodiment, the free end of the abutment rod 440 (i.e., the end away from the slider 430) is fixedly connected to an arc-shaped abutment plate 450 by welding or bolting. The arc-shaped abutment plate 450 can be made of metal sheet by stamping or engineering plastic by injection molding. The side facing the sidewall of the circuit breaker 10 is processed into a concave arc surface. The radius of curvature of the concave arc surface is precisely calculated and is the same as or similar to the radius of curvature of the arc-shaped support recess 410 on the first support plate 400, so that the two can together form a continuous, concentric wrap-around support structure.
[0140] When the operator slides the slider 430, causing the abutment rod 440 and its end arc-shaped abutment plate 450 to extend into the arc-shaped support recess 410, the concave arc surface of the arc-shaped abutment plate 450 gradually approaches the side wall of the circuit breaker 10. Because the curvature of the arc-shaped abutment plate 450 matches the curvature of the arc-shaped support recess 410, when the abutment rod 440 moves to the target position, the concave arc surface of the arc-shaped abutment plate 450 can completely conform to the outer contour of the side wall of the circuit breaker 10, forming surface contact support. At this time, the side wall of the circuit breaker 10 is simultaneously subjected to the macroscopic inclusive support of the arc-shaped support recess 410 and the local precise abutment support of the arc-shaped abutment plate 450, resulting in a uniform distribution of support force and effectively eliminating stress concentration problems that may occur with point contact.
[0141] In this embodiment, the arc-shaped abutment plate 450 and the arc-shaped support recess 410 form a concentric arc support system, which evenly distributes the supporting force on the side wall of the circuit breaker 10 along its contour, avoiding stress concentration caused by point contact or line contact. This surface contact support significantly reduces the risk of micro-movement or shaking of the circuit breaker 10 due to uneven force during assembly or flipping, providing a more stable foundation for subsequent precision assembly operations, which is especially crucial for ensuring the assembly quality of heavy-duty or precision circuit breakers 10.
[0142] In another possible embodiment, the second support frame 300 includes a second telescopic rod assembly 310 and a second rotating shaft 320. One end of the second telescopic rod assembly 310 is fixedly connected to the base 100, and the other end of the second telescopic rod assembly 310 is provided with a second bearing assembly 311. The second rotating shaft 320 is rotatably connected to the second bearing assembly 311, and the movable plate 500 is fixed to the second rotating shaft 320. The driving device 600 is connected to the second rotating shaft 320 to drive the second rotating shaft 320 to rotate, thereby driving the movable plate 500 to switch between a first position and a second position.
[0143] In this embodiment, the second support frame 300 is mainly composed of a second telescopic rod group 310, a second bearing group 311, and a second rotating shaft 320.
[0144] The second telescopic rod assembly 310 serves as the support column and height adjustment mechanism of the support frame. One end (fixed end) is securely fixed to the base 100 by bolts or welding. The second telescopic rod assembly 310 can be an electric push rod, a hydraulic cylinder, or a scissor lift mechanism. By controlling its extension and retraction, the entire upper structure of the support frame can be vertically raised and lowered, thereby flexibly adjusting the initial height of the movable plate 500 to accommodate circuit breakers 10 of different specifications.
[0145] At the other end (movable end) of the second telescopic rod assembly 310, a second bearing assembly 311 is provided. This bearing assembly preferably uses a self-aligning roller bearing or a mounted spherical roller bearing. These bearings can withstand radial loads and allow for a certain angular deviation, ensuring smooth and stable rotation. The second bearing assembly 311 is fixedly connected to the top end of the second telescopic rod assembly 310.
[0146] The second rotating shaft 320 passes through the inner ring of the second bearing assembly 311, achieving a smooth rotational connection.
[0147] The movable plate 500 is fixedly installed on the second rotating shaft 320 by means of flange connection or keyway fit, so that the movable plate 500 can rotate precisely together with the second rotating shaft 320.
[0148] The drive unit 600 is connected to the second rotating shaft 320 via a transmission connection. The drive unit 600 can be a servo motor with a reducer, whose output shaft is directly connected to one end of the second rotating shaft 320 via a coupling. Alternatively, a worm gear mechanism or a rack and pinion mechanism can be used to convert the output motion of the drive unit 600 into the rotational motion of the second rotating shaft 320.
[0149] When it is necessary to adapt to circuit breakers 10 of different heights or adjust the assembly posture, the second telescopic rod assembly 310 is first controlled to extend and retract, raising and lowering the movable plate 500 to a suitable height position. Then, the drive device 600 is activated, driving the second rotating shaft 320 to rotate. The second rotating shaft 320, through the stable support of the bearing assembly, drives the movable plate 500 fixed thereon to rotate smoothly around its axis, thereby precisely switching between a vertical state (first position) for easy assembly and a horizontal state (second position) for easy storage. Throughout the process, the height and angle of the movable plate 500 can be independently and precisely controlled.
[0150] This embodiment achieves stepless height adjustment through the telescopic rod assembly, combined with precise angle rotation controlled by the drive device 600. This allows the tooling to quickly adapt to a series of circuit breaker 10 products of different sizes and support point heights, realizing multi-purpose functionality. It significantly reduces the cost of purchasing or modifying special tooling due to product changes, and is particularly suitable for flexible production lines with multiple varieties and small batches.
[0151] Furthermore, the use of bearing assemblies to support the rotating shaft provides a stable, low-friction rotation center for the flipping motion, effectively avoiding the wobbling and misalignment problems that may exist in ordinary hinges. This makes the circuit breaker 10 move smoothly and controllably during attitude transitions, significantly reducing the risk of workpiece wobbling, collisions, or even overturning caused by instability in the mechanism, and providing a safety guarantee for high-quality assembly operations.
[0152] In one embodiment, the drive device 600 includes a drive motor 610 and a transmission assembly 620. The drive motor 610 is connected to the input end of the transmission assembly 620, and the output end of the transmission assembly 620 is connected to the second rotating shaft 320.
[0153] In this embodiment, the drive device 600 mainly includes two core components: a drive motor 610 and a transmission assembly 620.
[0154] The drive motor 610 serves as the power source and can be a servo motor, stepper motor, or a three-phase asynchronous motor with a reducer. A servo motor or stepper motor enables precise angle and position control, facilitating precise stopping of the movable plate 500 in a vertical or horizontal position via a control system, such as a PLC. If high control precision is not required, a robust, high-torque ordinary geared motor can also be selected. The drive motor 610 is securely mounted on the base 100 or the second support frame 300 via a motor mount, ensuring stability during operation.
[0155] The transmission assembly 620 is a key power transmission link connecting the drive motor 610 and the second rotating shaft 320. Its input end (such as a worm gear, pinion, or drive pulley) is connected to the output shaft of the drive motor 610. This connection method can be implemented in several ways:
[0156] Gear transmission: The transmission component 620 can be specifically defined as a worm gear mechanism or a cylindrical gear pair. For example, a worm is installed on the output shaft of the drive motor 610, and a worm wheel is installed at the end of the second rotating shaft 320. By utilizing the large reduction ratio and self-locking characteristics of the worm gear transmission, both torque increase and speed reduction can be achieved, and the position of the movable plate 500 can be automatically locked when the power is off to prevent reverse rotation due to the weight of the circuit breaker 10, ensuring safety and reliability.
[0157] Chain drive or synchronous belt drive: In applications involving long transmission distances or where rigid impacts need to be avoided, a combination of sprockets and chains or synchronous pulleys and belts can be used. This method effectively absorbs vibration and allows for a certain degree of center distance error during installation.
[0158] The output end of the transmission assembly 620 (such as a worm gear, driven gear, or driven sprocket) is coaxially fixed to the second rotating shaft 320 via a key connection or flange connection. In this way, the rotational power generated by the drive motor 610 is reliably transmitted to the second rotating shaft 320 after the speed and torque are changed by the transmission assembly 620, thereby driving the movable plate 500 to rotate precisely.
