Description

Technical Field

[0001] This utility model relates to the field of housings, and more particularly to a processing device for circuit breaker housings. Background Technology

[0002] A circuit breaker is an electrical device used to protect circuits. Its main function is to automatically cut off the current when an overload or short circuit occurs, thereby preventing damage to the electrical system or fire. The molding precision and structural strength of the circuit breaker housing directly affect the overall performance and safety of the circuit breaker. As an important component that carries and protects circuit components, the efficiency and precision of the circuit breaker housing's manufacturing process directly affect the overall performance and service life of the circuit breaker.

[0003] Circuit breaker housings require multiple irregularly shaped holes on their surface to meet wiring, heat dissipation, and assembly needs. Positioning accuracy directly affects the assembly quality and operational safety of the circuit breaker. Traditional equipment for machining irregularly shaped holes in circuit breaker housings mainly consists of a worktable and a milling or drilling mechanism. During machining, the housing must be manually placed on the worktable and aligned with the baseline. This process is prone to misalignment, resulting in low efficiency and, over long-term production, unstable quality and increased production costs. Furthermore, manual operation suffers from large positioning errors and poor machining consistency, making it difficult to meet the demands of modern industry for high-precision, high-volume production, especially in the machining of complex housing structures.

[0004] To address these issues, a circuit breaker housing processing device is proposed here. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies that rely on manual visual alignment during the casing processing, which makes the casing prone to longitudinal or lateral displacement, this utility model provides a circuit breaker casing processing device.

[0006] This utility model is achieved using the following technical solution: A circuit breaker housing processing device includes a workbench, with mounting platforms symmetrically arranged above the workbench. A tray is provided on the top of the mounting platform, and a positioning groove is provided in the tray. A housing is embedded in the positioning groove. A gear is provided at the center of the top of the workbench. A first slide rail and a second slide rail are symmetrically arranged around the gear. A cylinder is provided on one side of the workbench. A piston rod is built into the cylinder. The front end of the piston rod is connected to a first transmission arm through a connecting seat. A first toothed plate that meshes with the gear is provided at the bottom of the first transmission arm. A first slider is provided at the bottom of the first toothed plate. The first slider is embedded in the first slide rail and can slide along it. A second transmission arm is provided above the second slide rail, and a second toothed plate that meshes with the gear is provided at the bottom of the second toothed plate. A second slider is provided at the bottom of the second toothed plate. The second slider is embedded in the second slide rail and can slide along it. The cylinder pushes the piston rod to extend and retract, causing the first transmission arm and the second transmission arm to move synchronously in opposite directions or in opposite directions.

[0007] As a preferred embodiment of this utility model, the first transmission arm and the second transmission arm are provided with clamping plates on their inner sides, and multiple extrusion components are installed on the clamping plates. Each extrusion component includes a spring and a contact plate. One end of the spring is fixed inside the clamping plate, and the other end is connected to the contact plate.

[0008] As a preferred embodiment of the present invention, the end of the first transmission arm is provided with a first transmission slider, and the first transmission slider is movably connected to the second slide rail. The second transmission arm is provided with a second transmission slider at its end, and the second transmission slider is movably connected to the first slide rail.

[0009] In a preferred embodiment of this utility model, the gear is located directly below the tray, and the gear is always engaged with the first toothed plate and the second toothed plate.

[0010] As a preferred embodiment of this utility model, the end face of the touch plate is provided with an anti-slip sticker.

[0011] As a preferred embodiment of this utility model, the tray is connected to the mounting platform by a detachable bolt connection.

[0012] Compared with existing technologies, the advantages of this utility model are: 1. By placing the housing in the positioning groove of the tray, the housing is initially fixed by the positioning groove. Then, the piston rod is pushed out by the cylinder, which drives the first transmission arm and the second transmission arm to move synchronously in opposite directions along the slide rail. The contact plates on both sides of the clamping plate are tightly attached to the outer wall of the housing under the action of the spring force, realizing self-adaptive clamping. This effectively avoids displacement or deformation of the housing during processing, thereby improving processing accuracy and stability.

[0013] 2. The tray is detachably connected to the mounting platform, making it easy to replace the tray with a suitable one according to the housing specifications, thus improving the versatility and changeover efficiency of the device. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example: Please see Figures 1-5 A circuit breaker housing processing device includes a workbench 1, with mounting platforms symmetrically arranged above the workbench 1. A tray 13 is provided on the top of the mounting platform 12, and a positioning groove 131 is provided in the tray 13. A housing 2 is embedded in the positioning groove 131. A gear 3 is provided at the center of the top of the workbench 1. A first slide rail 4 and a second slide rail 41 are symmetrically arranged around the gear 3. A cylinder 11 is provided on one side of the workbench 1. A piston rod 111 is built into the cylinder 11. The front end of the piston rod 111 is connected to a first transmission arm 5 through a connecting seat 51. A first toothed plate 52 that meshes with the gear 3 is provided at the bottom of the first transmission arm 5. A first slider 521 is provided at the bottom of the first toothed plate 52. The first slider 521 is embedded in the first slide rail 4 and can slide along it. In this embodiment, please refer specifically to Figure 1 and... Figure 2A mounting platform 12 is symmetrically arranged at the top center of the workbench 1. A tray 13 is connected to the top of the mounting platform 12. The tray 13 is connected to the mounting platform 12 by a detachable bolt connection, which facilitates quick replacement of the appropriate tray 13 according to the specifications of the housing 2. The tray 13 has a positioning groove 131, which matches the shape of the housing 2 and can effectively fix the position of the housing 2. By placing the housing 2 in the positioning groove 131 of the tray 13, the housing 2 is initially fixed by the positioning groove 131. A gear 3 is located at the top center of the workbench 1, between the mounting platforms 12, and the gear 3 is directly mounted on the workbench. At the top, gear 3 is located directly below tray 13 and can rotate freely. The first slide rail 4 and the second slide rail 41 are symmetrically distributed on both sides of gear 3, and their axes are consistent with the radial direction of gear 3. Both the first slide rail 4 and the second slide rail 41 are fixed to the surface of worktable 1. A cylinder 11 is also provided at the top of worktable 1. The cylinder 11 is located on the side close to the first slide rail 4. The cylinder 11 is horizontally installed and the extension and retraction direction of the piston rod 111 is parallel to the extension direction of the first slide rail 4. The front end of the piston rod 111 is hinged to the first transmission arm 5 through the connecting seat 51, which drives the first transmission arm 5 to slide back and forth along the first slide rail 4.

[0017] A second transmission arm 6 is provided above the second slide rail 41, and a second toothed plate 61 that meshes with the gear 3 is provided at its bottom. A second slider 611 is provided at the bottom of the second toothed plate 61. The second slider 611 is embedded in the second slide rail 41 and can slide along it. The cylinder 11 pushes the piston rod 111 to extend and retract, driving the first transmission arm 5 and the second transmission arm 6 to move synchronously towards or away from each other.

[0018] In this embodiment, specific reference is made. Figure 3 as well as Figure 4 The main function of the second transmission arm 6 is to respond to the rotational motion of the gear 3. Through the meshing of the second toothed plate 61 with the gear 3, the second transmission arm 6 moves synchronously in the opposite direction with the first transmission arm 5, thereby realizing the coordinated opening and closing of the clamping components.

[0019] When the piston rod 111 extends, it pushes the first transmission arm 5 to move towards the gear 3, causing the first toothed plate 52 to mesh with the gear 3 and drive it to rotate. This synchronously drives the second toothed plate 61 and the second transmission arm 6, which are meshed with the gear 3, to move, realizing the linkage opening and closing of the clamping components on both sides. The main function of the first transmission arm 5 is to transmit the thrust generated by the cylinder 11, converting the linear motion of the piston rod 111 into the rotational motion of the gear 3, and then driving the second transmission arm 6 to operate synchronously through the gear 3. When the piston rod 111 extends, the first transmission arm 5 and the second transmission arm 6 move away from each other, causing the clamping components to open. After the housing 2 is inserted, the piston rod 111 retracts, driving the first transmission arm 5 to move towards the cylinder 11. The first toothed plate 52 drives the gear 3 to rotate in the opposite direction, thereby causing the second transmission arm 6 to move towards the center synchronously, realizing the clamping of the housing 2. The entire device is accurately positioned, low in cost, and easy to operate, making it suitable for the assembly process of the housing 2 in mass production.

[0020] Specifically, the first transmission arm 5 and the second transmission arm 6 are provided with clamping plates 7 on their inner sides. Multiple extrusion components 8 are installed on the clamping plates 7. Each extrusion component 8 includes a spring 81 and a contact plate 82. One end of the spring 81 is fixed inside the clamping plate 7, and the other end is connected to the contact plate 82.

[0021] In this embodiment, the clamping plate 7 is specifically matched with the outer wall of the housing 2 and can fit against the outer surface of the housing 2. Multiple pressing components 8 are distributed on the inner side of the clamping plate 7 on the first transmission arm 5 and the second transmission arm 6. The pressing component 8 is composed of a spring 81 and a contact plate 82. Under the action of external force, the contact plate 82 can compress the spring 81 and generate buffer pressure to ensure that the force is applied evenly to the surface of the housing 2 during the clamping process and to avoid damage. The end face of the contact plate 82 is provided with an anti-slip sticker 83, which is made of rubber and can effectively increase friction.

[0022] Specifically, the first transmission arm 5 is provided with a first transmission slider 53 at its end, and the first transmission slider 53 is movably connected to the second slide rail 41; The second transmission arm 6 has a second transmission slider 62 at its end, and the second transmission slider 62 is movably connected to the first slide rail 4.

[0023] In this embodiment, specific reference is made. Figure 4 The first transmission arm 5 and the second transmission arm 6 have a symmetrical structure with a convex center and concave sides. When they retract, the clamping plates 7 on both sides move towards the center synchronously. The first transmission arm 5 and the second transmission arm 6 will not contact the tray 13, ensuring that they work independently and avoiding motion interference. One end of the first transmission arm 5 has a first toothed plate 52 at the bottom and the other end has a first transmission slider 53. The first transmission slider 53 is movably connected to the second slide rail 41. When the piston rod 111 of the cylinder 11 extends, the first transmission slider 53 at the bottom slides along the second slide rail 41 towards the gear 3. The second transmission arm 6 has a second toothed plate 61 at one end and a second transmission slider 62 at the other end. The second transmission slider 62 is movably connected to the first slide rail 4. After the second toothed plate 61 receives power from the gear 3, the second transmission slider 62 moves along the first slide rail 4 to maintain the synchronicity of the movement of the second transmission arm 6 and the first transmission arm 5.

[0024] The gear 3 is always engaged with the first toothed plate 52 and the second toothed plate 61.

[0025] The principle of this utility model is as follows: First, select a tray 13 of appropriate size according to the size of the shell 2, install the support bolts on the mounting platform 12, place the shell 2 in the positioning groove 131 of the tray 13, and use the positioning groove 131 to initially fix the shell 2.

[0026] When cylinder 11 is activated, piston rod 111 retracts, causing the first toothed plate 52 at the bottom of the first transmission arm 5 to move along the first slide rail 4. This causes the first toothed plate 52 to mesh with gear 3 and rotate, thereby synchronously driving the second toothed plate 61 and the second transmission arm 6, which mesh with gear 3, to move along the second slide rail 41. As piston rod 111 retracts, clamping plates 7 move towards each other. The contact plate 82 on the inner side of clamping plate 7 is tightly attached to the outer wall of housing 2 under the elastic force of spring 81. Anti-slip sticker 83 contacts the surface of housing 2 to increase friction and prevent housing 2 from sliding during clamping. At this point, clamping is complete, cylinder 11 stops, clamping force is stable, and housing 2 is firmly fixed on tray 13. Subsequent assembly or testing can then be performed. When the operation is completed, piston rod 111 of cylinder 11 extends, driving the first transmission slider 53 to slide in the opposite direction along the second slide rail 41. The first transmission arm 5 and the second transmission arm 6 move in opposite directions synchronously under the transmission of gear 3, and clamping plate 7 moves away from the center of housing 2, completing the disengagement.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
