Description

Technical Field

[0001] The present application relates to the technical field of circuit breaker processing, and in particular to a circuit breaker housing deburring device. Background Art

[0002] Plastic circuit breakers are key components in power distribution systems, and the manufacturing quality of their bases and shell covers is critical. The base is usually produced using an injection molding process, which, while bringing efficient production, will inevitably leave some burrs on the base surface. These burrs not only affect the appearance quality of the product, but may also have an adverse effect on the electrical and mechanical properties of the circuit breaker. Therefore, deburring the base surface is an indispensable part of the production process.

[0003] However, existing deburring equipment faces certain limitations when dealing with base burrs. Specifically, the equipment can usually only deburr one side of the base. Once the burrs on that side are removed, the staff needs to manually adjust the clamping state of the base so that the other side can be treated in the same way. This processing method that relies on manual adjustment is not only time-consuming and labor-intensive, but also prone to human errors, resulting in unstable processing results.

[0004] This limitation is particularly prominent in mass production. As production demand increases, the frequency and time cost of manual adjustments also increase, seriously restricting the improvement of production efficiency. In addition, manual adjustments may increase the risk of product damage, further affecting the stability and reliability of the production line, and there is room for improvement. Summary of the invention

[0005] The purpose of this application is to provide a circuit breaker casing deburring device to solve the problem that the deburring processing efficiency of the plastic shell base in the above-mentioned related technology is low and cannot meet the needs of mass production.

[0006] The circuit breaker housing deburring device provided in this application adopts the following technical solution: A deburring device for a circuit breaker casing comprises a base, a grinding wheel located above the base, and a first power member that drives the grinding wheel to rotate, and a second power member that drives the grinding wheel to move in the horizontal and vertical directions is also provided on the base; a clamping plate is provided below the grinding wheel, and a processing through hole is opened in the middle of the clamping plate; two supporting plates are relatively fixed on the base, and the opposite side surfaces of the clamping plate are respectively rotatably connected to the side surfaces of the two supporting plates close to each other, and a first driving member that drives the clamping plate to rotate is fixed on the supporting plate; clamping assemblies for clamping the workpiece are provided on the opposite edges of the upper side of the clamping plate; the grinding wheel can grind the bottom side of the workpiece through the processing through hole.

[0007] By adopting the above technical solution, the grinding wheel in the equipment can not only move in the horizontal direction, but also adjust its position in the vertical direction. At the same time, the clamping plate can rotate relative to the support plate, so that the grinding wheel can easily reach all sides of the base, including the top, bottom and sides. The clamping assembly ensures that the workpiece is stable and motionless during the grinding process, which improves the accuracy and safety of grinding. The first power part drives the grinding wheel to rotate, and the second power part is responsible for the spatial movement of the grinding wheel. The two work together to greatly improve the efficiency of deburring. In addition, the equipment reduces the reliance on manual adjustment, reduces the risk of human error and product damage, ensures the stability and consistency of the processing effect, and is very suitable for the needs of mass production, effectively improving the overall efficiency and reliability of the production line.

[0008] Optionally, a collecting box placed on the side surface of the base is provided between the two support plates, and a limiting convex plate abutting against the outer side surface of the collecting box is fixedly provided on the side surfaces of the two support plates close to each other, and the opening of the collecting box is upward and located below the clamping plate; a first through hole is provided on the upper side surface of the base, and a second through hole overlapping the first through hole is provided on the bottom side of the collecting box; a hose, a negative pressure pump and a receiving box are provided in the base, the extraction end of the negative pressure pump is fixedly connected to the receiving box, one end of the hose is fixedly connected to the receiving box, and the other end of the hose passes through the first through hole and is fixedly connected to the inner wall of the second through hole.

[0009] By adopting the above technical solution, the collection box arranged between the two support plates can conveniently collect the debris and dust generated during the grinding process, avoiding these impurities from polluting the equipment and the working environment. The design of the limiting convex plate ensures the stable placement of the collection box, while facilitating cleaning and replacement. The collection box cooperates with the first through hole on the base and the hose and the second through hole, so that the debris can be directly extracted by the negative pressure pump and sent to the receiving box, realizing the rapid cleaning and centralized treatment of the debris. This design not only keeps the working area clean, but also effectively reduces the downtime for cleaning, further improving production efficiency, but also reflects the concern for environmental protection and employee health, and enhances the practicality and market competitiveness of the equipment.

[0010] Optionally, the first through hole is a waist-shaped hole, the support plate is slidably disposed on the upper side of the base, and a limiting member for fixing the position of the support plate after sliding is provided above the base.

[0011] By adopting the above technical solution, the first through hole is designed as a waist-shaped hole, allowing the position of the collection box on the base to have a certain adjustment range to meet the processing requirements of workpieces of different sizes or shapes. The support plate is slidably arranged on the side of the base, and is equipped with a limiter to fix the position of the support plate after sliding. This design allows the position of the support plate to be flexibly adjusted and firmly locked. This flexible configuration improves the versatility of the equipment.

[0012] Optionally, the limit member includes a plurality of limit rods slidably arranged on the support plate along the vertical direction, a locking bolt fixing the sliding state of the limit rods, and a plurality of limit holes evenly arranged on the base for inserting the lower ends of the limit rods; a fixing plate is fixedly arranged on the outer periphery of the upper part of the limit rod, a fixing through hole is arranged on the fixing plate, and a fixing screw hole is arranged on the support plate, and the fixing screw hole coincides with the fixing through hole when the limit rod is inserted into the limit hole, and the fixing bolt can penetrate the fixing through hole and then be screwed into the fixing screw hole.

[0013] By adopting the above technical solution, the limit rod is slid on the support plate in the vertical direction, and its sliding state can be fixed by the locking bolt, so that the operator can easily adjust the position of the support plate. The cooperation between the limit socket on the base and the lower end of the limit rod further ensures the accuracy and stability of the position of the support plate. At the same time, the combined design of the fixing plate, the fixing through hole, the fixing screw hole and the fixing bolt provides an additional fixing means for the limit rod, which can keep the support plate stable and not shake even in a high-intensity working environment. This design not only simplifies the process of equipment adjustment, but also improves the stability and safety of equipment operation, providing a strong guarantee for efficient and accurate deburring operations.

[0014] Optionally, a guide through hole is provided on the support plate in the vertical direction, and an extension rod penetrating the guide through hole is fixedly provided on the upper portion of the limiting rod.

[0015] By adopting the above technical solution, the guide through hole opened in the vertical direction on the support plate cooperates with the extension rod fixed on the upper part of the limit rod, playing a guiding and supporting role, making the limit rod more stable during the sliding process and less likely to deviate or shake. This design not only helps the operator to adjust the position of the support plate more accurately, but also provides better stability when fixing, ensuring that the support plate remains stable during the processing process.

[0016] Optionally, protective plates are hinged on two opposite edges of the collection box, and the protective plates can be rotated upward to a vertical state. A positioning piece for locking the protective plates in the vertical state is provided on the support plate.

[0017] By adopting the above technical solution, the hinged protective plates on the two opposite edges of the collection box can be rotated upward to a vertical state when necessary, effectively covering the opening of the collection box to prevent the debris generated during the grinding process from splashing out and causing harm to the operator or polluting the working environment. The positioning piece set on the support plate can lock the protective plate in the vertical state to ensure that it is stable and immovable, further enhancing the reliability of safety protection.

[0018] Optionally, the positioning member includes a positioning rod located between the two support plates and a positioning block fixed at one end of the positioning rod; the end of the positioning rod away from the positioning block is coaxially fixedly connected to the end of the extension rod, and a positioning notch is provided on the lower side of the positioning block, and the upper edge of the protective plate is inserted into the positioning notch when the limiting rod moves down and is inserted into the limiting hole.

[0019] By adopting the above technical solution, when the limit rod moves down and inserts into the limit socket, the upper edge of the protective plate will cleverly fit into the positioning notch on the lower side of the positioning block, thereby achieving a stable locking of the protective plate. This design not only simplifies the locking operation and improves work efficiency, but also ensures the stability of the protective plate during the grinding process, effectively prevents the splashing of debris, and improves the safety performance of the equipment. At the same time, the locking mechanism is compact and easy to maintain, reflecting the ingenuity and practicality of the equipment design.

[0020] Optionally, the two vertical side surfaces opposite to the limiting protrusion are provided with adjusting rods, and the lower ends of the adjusting rods are hinged to the lower part of the limiting protrusion; the adjusting rods can be rotated downward to a horizontal state abutting against the outer side surface of the collection box; when the adjusting rods are rotated upward to a vertical state, they can abut against the lower side surface of the end of the extension rod, and the limiting rods are disengaged from the limiting socket in this state of the adjusting rods.

[0021] By adopting the above technical solution, the adjustment rod provided on the limit convex plate can be rotated downward to a horizontal state abutting against the outer side of the collection box, thereby achieving a stable fixation of the collection box. When the collection box needs to be disassembled, the adjustment rod only needs to be rotated upward to a vertical state, at which time the adjustment rod will abut against the lower side of the end of the extension rod, and the limit rod will be pushed out of the limit socket, so that the fixation of the collection box can be easily released. This design not only simplifies the disassembly process of the collection box and improves work efficiency, but also enables operators to clean and replace the collection box more conveniently.

[0022] Optionally, an elastic clip is provided on the outer periphery of the end of the adjusting rod away from the limiting protrusion, a first groove for the elastic clip to be inserted into is formed on the limiting protrusion, and a second groove for the elastic clip to be inserted into is formed on the outer surface of the collection box.

[0023] By adopting the above technical solution, when the adjusting rod is rotated upward to a vertical state, the elastic clamp is snapped into the first groove; when it is rotated downward to a horizontal state, the elastic clamp is snapped into the second groove, thereby improving the installation stability of the adjusting rod in the two states.

[0024] Optionally, an installation cavity connected to the second through hole is provided on two opposite vertical side surfaces at the bottom of the collection box, and a sealing plate is slidably provided inside the installation cavity, and an elastic extrusion member for driving the two sealing plates to slide toward each other is fixedly provided; the outer end of the sealing plate extends to the outside of the collection box, and a clearance gap is provided on the upper side surface of the outer end of the sealing plate; the ends of the two sealing plates close to each other are inserted into the second through hole under the action of the elastic extrusion member to seal it; when the adjusting rod is rotated downward and stuck in the clearance gap, the sealing plate overcomes the elastic force of the elastic extrusion member and slides out of the second through hole.

[0025] By adopting the above technical solution, when the collection box is not installed stably, that is, the adjustment rod is not rotated downward to fit into the clearance gap at the outer end of the blocking plate, the two blocking plates tightly seal the second through hole under the action of the elastic extrusion member, effectively preventing debris from leaking out of the second through hole before the collection box is stabilized, thereby ensuring the cleanliness and safety of the working environment. Only when the collection box is correctly installed, the adjustment rod is inserted into the clearance gap, and the blocking plate overcomes the elastic force of the elastic extrusion member and slides out of the second through hole, can the corresponding collection components (such as the negative pressure pump and hose system) be normally activated to start collecting the debris generated during the grinding process. This design not only enhances the safety performance of the equipment and prevents the problem of debris leakage caused by the unstable collection box, but also ensures that the collection components are activated at the right time through the intelligent linkage mechanism, thereby improving the overall operating efficiency and practicality of the equipment.

[0026] In summary, this application includes the following beneficial technical effects: The grinding wheel in the device can not only move in the horizontal direction, but also adjust its position in the vertical direction. At the same time, the clamping plate can rotate relative to the supporting plate, so that the grinding wheel can easily reach all sides of the base, including the top, bottom and both sides.
