Description

Technical Field

[0001] This utility model relates to the field of water pump processing, specifically to an automated device for deburring water pump bodies and impellers. Background Technology

[0002] Burrs are a common technical problem in metal processing, especially in the turning and milling of precision components such as pump bodies and impellers, where sharp metal burrs easily form on the end faces. These burrs not only affect the sealing and fluid performance of components, but can also cause fatigue damage due to stress concentration, and even lead to system leaks or failures. Currently, the industry generally relies on manual grinding to remove burrs, but this method has the following main drawbacks: 1. Low efficiency of manual polishing: Manual operation relies on worker experience, and it takes a long time to process complex structures or internal burrs, making it difficult to meet the needs of mass production.

[0003] 2. Labor intensity and environmental hazards: Manual grinding requires high-intensity repetitive actions, and metal dust floats in the air for a long time. Even with a dust mask, there are still occupational health risks. Long-term operation poses a health threat to the operator's respiratory system.

[0004] 3. Poor quality consistency: Manual polishing is prone to uneven surfaces or residual microburrs due to differences in operation, which affects the assembly accuracy and service life of parts.

[0005] With the increasing demand for automation and green production in the manufacturing industry, the development of efficient and environmentally friendly automatic deburring equipment has become an urgent need. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automated device for deburring pump bodies and impellers. It has a deburring mechanism with up-and-down floating and angle tilting to adapt to the removal of burrs from parts (pump bodies or impellers) of different structures and sizes. The enclosed working environment allows dust to be collected in a concentrated manner, preventing it from being dispersed into the external air environment and improving the working environment.

[0007] The purpose of this utility model is achieved through the following technical solution: an automated device for deburring the pump body and impeller of a water pump, comprising: The frame has an electrical control box at its bottom and a tabletop at the top of the electrical control box. Two first guide rails are set parallel to each other on the table panel, and a rack is set on the table panel between the two first guide rails; The chuck is mounted on the platform on one side of the first guide rail. The bottom of the chuck is connected to and driven by a chuck motor located in the electrical control box. The chuck is used to hold parts, so that the parts rotate under the drive of the chuck motor. A deburring mechanism includes a drive motor, a sliding plate, and a grinding assembly. The drive motor is fixed on the sliding plate, and the grinding assembly is slidably mounted on a first guide rail via the sliding plate. A gear is mounted on the shaft end of the drive motor and meshes with a rack for transmission. The drive motor controls the grinding assembly to approach and contact the part, thereby removing burrs. The machine cover, which covers the tabletop and is connected to the frame, forms a closed processing chamber to prevent metal dust generated during deburring from escaping.

[0008] As a further technical solution, the grinding assembly includes an asynchronous motor bracket mounted on a sliding plate. A second guide rail is provided on the asynchronous motor bracket along its length. The asynchronous motor is slidably mounted on the second guide rail via an asynchronous motor mounting plate. Multiple steel wire grinding wheels are installed at the output end of the asynchronous motor for removing burrs from the parts. A lead screw is also provided on the asynchronous motor bracket for driving the asynchronous motor mounting plate and the asynchronous motor to slide along the second guide rail.

[0009] As a further technical solution, the asynchronous motor controls the rotation direction of the wire grinding wheel to be opposite to the rotation direction of the part, and the asynchronous motor adjusts the speed by controlling the motor frequency converter through the electrical control box to remove burrs of different sizes; a motor baffle is set to semi-enclose the outer circumference of the wire grinding wheel, and a flexible hose is installed on the motor baffle and connected to an external vacuum cleaner to collect metal dust, burr fragments and debris.

[0010] As a further technical solution, the lead screw includes a lead rod disposed on the back of the asynchronous motor bracket and parallel to the second guide rail. The lead rod and the lead screw motor are driven by bevel gear meshing. A nut mounted on the lead rod passes through the asynchronous motor bracket and is connected to the asynchronous motor mounting plate.

[0011] As a further technical solution, a contact plate is provided on the outside of the nut, and an upper limit switch and a lower limit switch are respectively provided on the asynchronous motor brackets on both sides of the contact plate. The contact plate controls the upper limit position by contacting the upper limit switch, and the contact plate controls the lower limit position by contacting the lower limit switch.

[0012] As a further technical solution, the asynchronous motor bracket and the sliding plate are rotatably connected by a pivot pin. A third guide rail is set on the end of the asynchronous motor bracket away from the pivot pin. An adapter is installed on the slider of the third guide rail to connect the piston rod of the servo electric cylinder. The servo electric cylinder is supported on the sliding plate by the asynchronous motor angle bracket. The rotation of the asynchronous motor bracket is controlled by the extension and retraction of the servo electric cylinder, thereby adjusting the tilt angle of the wire grinding wheel to remove burrs from parts with larger chamfering dimensions.

[0013] As a further technical solution, a limit switch is installed on the sliding plate to cooperate with the limit baffle fixed on the table panel to limit the sliding stroke.

[0014] As a further technical solution, the machine cover is equipped with indicator lights and a touch screen system. The indicator lights are used to display the operating status of the equipment, and the touch screen system is electrically connected to the electrical control box to send control signals to the electrical control box. The electrical control box controls the deburring mechanism and the chuck motor through electrical connection.

[0015] The beneficial effects of this utility model are as follows: 1. Improve processing efficiency: By using automation technologies such as servo motors and multi-axis linkage, continuous operation can be achieved by replacing manual labor, thus shortening the processing cycle of a single piece; 2. Eliminate health hazards: The integrated enclosed processing chamber and dust collection system prevent metal dust from escaping and improve the working environment; 3. Ensure deburring quality: Utilize flexible contact processes such as steel wire wheels and servo motor control to ensure that sharp edges are removed while avoiding damage to the substrate.

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings: Example 1: As shown in the attached document Figures 1-9 As shown, an automated device for deburring pump bodies and impellers includes a frame 1, a cover 2, indicator lights 3, a touch screen system 4, an electrical control box 5, casters 6, a platform 7, a first guide rail 8, a rack 9, a deburring mechanism 10, a chuck 11, a component 12, a chuck motor 13, a drive motor 10-1, a sliding plate 10-2, an asynchronous motor bracket 10-3, a second guide rail 10-4, an asynchronous motor mounting plate 10-5, an asynchronous motor 10-6, and a motor baffle. 10-7, Wire grinding wheel; 10-8, Shaft pin; 10-9, Lead screw motor; 10-10, Third guide rail; 10-11, Lead screw; 10-12, Nut; 10-13, Upper limit switch; 10-14, Lower limit switch; 10-15, Servo electric cylinder; 10-16, Asynchronous motor angle bracket; 10-17, Bevel gear; 10-18, Contact plate; 10-19, Adapter; 10-20, Limit switch; 10-21, Limit baffle; 10-22, and Gear; 10-23.

[0027] Reference Appendix Figure 1 , 2 An electrical control box 5 is installed at the bottom of the frame 1, and a platform 7 is installed on top of the electrical control box 5. A caster 6 is installed at each of the four corners of the bottom of the frame 1 to facilitate the overall movement of the equipment. Figure 3 , 4 As shown in Figure 5, two first guide rails 8 are arranged parallel to each other on the table panel 7, and a rack 9 is provided between the two first guide rails 8, with the rack 9 fixed to the table panel 7. (See attached figure) Figure 3The chuck 11 is positioned on the platform 7 on one side (left side) of the first guide rail 8. The bottom of the chuck 11 is connected to and driven by a chuck motor 13 located inside the electrical control box 5. The chuck 11 can hold parts 12 (in this embodiment, an impeller is used as an example; in practice, both the pump body and the impeller are applicable), allowing the parts 12 to rotate under the drive of the chuck motor 13. Furthermore, as... Figure 1 As shown, the machine cover 2 encloses the worktable 7 and is connected to the frame 1, forming a closed processing chamber. This prevents metal dust generated during deburring from escaping, improving the working environment and eliminating health hazards. Preferably, the machine cover 2 is equipped with indicator lights 3 and a touch screen system 4. The indicator lights 3 can display the equipment's operating status (such as running, stopped, alarm, etc.). The touch screen system 4 is electrically connected to the electrical control box 5, sending control signals to the electrical control box 5 and displaying the real-time operating status of the equipment. The electrical control box 5 controls the deburring mechanism 10 and the chuck motor 13 via electrical connection. The electrical control box 5 can process signals received by the touch screen system 3 and other external sensors, and control various components of the equipment based on signal feedback.

[0028] like Figure 4 , 5 As shown, the deburring mechanism 10 includes a drive motor 10-1, a sliding plate 10-2, and a grinding assembly. The drive motor 10-1 is fixedly supported on the sliding plate 10-2. The grinding assembly includes an asynchronous motor bracket 10-3 and an asynchronous motor 10-6. The asynchronous motor bracket 10-3 is movably mounted (rotatably connected) on the sliding plate 10-2. Two second guide rails 10-4 are arranged along the length of the asynchronous motor bracket 10-3. The asynchronous motor 10-6 is slidably mounted on the second guide rails 10-4 via an asynchronous motor mounting plate 10-5 (and a corresponding slider). Multiple wire grinding wheels 10-8 are mounted on the output end of the asynchronous motor 10-6. The burrs are removed by the contact of the wire grinding wheels 10-8 with the part 12. Preferably, the asynchronous motor 10-6 can control the rotation direction of the wire grinding wheels 10-8 to be opposite to the rotation direction of the part 12, and the asynchronous motor 10-6 can adjust its speed through the control of the motor frequency converter via the electrical control box 5, thus enabling the removal of burrs of different sizes. Preferably, a motor baffle 10-7 is provided in a semi-encircling manner around the outer periphery of the wire grinding wheel 10-8. A hose is installed on the motor baffle 10-7 and connected to an external vacuum cleaner, which can collect metal dust, burrs and debris.

[0029] Furthermore, such as Figure 6As shown, a set of lead screws is also provided on the asynchronous motor bracket 10-3. The lead screws can drive the asynchronous motor mounting plate 10-5 and the asynchronous motor 10-6 to slide along the second guide rail 10-4. The lead screw includes a lead rod 10-12 and a nut 10-13 mounted on the lead rod 10-12. The lead rod 10-12 is located on the back of the asynchronous motor bracket 10-3 and is parallel to the second guide rail 10-4. The lead rod 10-12 is driven by the lead screw motor 10-10 through the meshing of a bevel gear 10-18. The nut 10-13 passes through the asynchronous motor bracket 10-3 (the asynchronous motor bracket 10-3 has a clearance space for the nut 10-13 in the middle to avoid interference) and is connected to drive the asynchronous motor mounting plate 10-5. Preferably, a contact plate 10-19 is provided on the outside of the nut 10-13. An upper limit switch 10-14 (located at the upper middle part of the asynchronous motor bracket 10-3) and a lower limit switch 10-15 (located at the lower middle part of the asynchronous motor bracket 10-3) are respectively provided on the asynchronous motor bracket 10-3 on both sides of the contact plate 10-19. The contact plate 10-19 controls the upper limit position by contacting the upper limit switch 10-14, and the contact plate 10-19 controls the lower limit position by contacting the lower limit switch 10-15, so as to prevent the asynchronous motor 10-6 from moving excessively and causing damage to the equipment.

[0030] Reference Appendix Figure 6 , 7 8. The lower part of the asynchronous motor bracket 10-3 is rotatably connected to the sliding plate 10-2 via a pivot pin 10-9. A third guide rail 10-11 is provided on the upper part of the asynchronous motor bracket 10-3 (i.e., the end away from the pivot pin 10-9). An adapter 10-20 is installed on the slider corresponding to the third guide rail 10-11. The piston rod of the servo electric cylinder 10-16 is connected to the slider via the adapter 10-20 (allowing the angle of the piston rod relative to the slider to be changed). At the same time, the servo electric cylinder 10-16 is supported on the sliding plate 10-2 via the asynchronous motor angle bracket 10-17. When the servo electric cylinder 10-16 extends or retracts, the piston rod extends or retracts. Under the action of the adapter 10-20, the slider slides along the third guide rail 10-11, thereby controlling the rotation of the asynchronous motor bracket 10-3 to adjust the tilt angle of the wire grinding wheel 10-8, thus achieving burr removal for parts 12 with larger chamfer dimensions.

[0031] Furthermore, such as Figure 5 As shown, the grinding assembly is slidably mounted on the first guide rail 8 via a sliding plate 10-2. A gear 10-23 is mounted on the shaft end of the drive motor 10-1 and meshes with the rack 9 for transmission. By controlling the drive motor 10-1 to bring the grinding assembly closer to and contact the part 12, burr removal can be achieved. Preferably, as shown... Figure 4 , 9As shown, a limit switch 10-21 is installed at the bottom of the sliding plate 10-2. The limit switch 10-21 can cooperate with the limit baffle 10-22 fixed on the table panel 7 to limit the sliding stroke.

[0032] Example 2: A method for deburring a water pump body and impeller, using the automated equipment for deburring water pump bodies and impellers described in Example 1, including the following steps: S1. Open the machine cover 2, place the part 12 on the chuck 11 and fix it, then close the machine cover 2 tightly to seal it; S2. The chuck motor 13 is started via the touch screen system 4, causing the part 12 to rotate. Simultaneously, the drive motor 10-1 is started, causing the asynchronous motor bracket 10-3 and its wire grinding wheel 10-8 to approach the part 12 and begin deburring. During this process, the touch screen system 4 sends a speed adjustment signal, and the frequency converter of the asynchronous motor 10-5 is controlled via the electrical control box 5 to adjust the speed of the wire grinding wheel 10-8. This allows for the removal of burrs of different sizes for different parts 12.

[0033] S3. Then, the touch screen system 4 is used to control the start of the lead screw motor 10-10, which drives the asynchronous motor mounting plate 10-5 to move up and down through the nut 10-13, so as to remove burrs from the parts 12 at different heights. S4. Next, the servo electric cylinder 10-16 is started using the touch screen system 4. The servo electric cylinder 10-16 pushes the asynchronous motor bracket 10-3 to rotate relative to the sliding plate 10-2, causing the wire grinding wheel 10-8 to tilt, thereby removing burrs from the part 12 with a large chamfer size. After the burrs are removed, the machine cover 2 can be opened to take out the part 12.

[0034] This invention utilizes a deburring mechanism with vertical floating (second guide rail 10-4 and asynchronous motor mounting plate 10-5) and angular tilting (asynchronous motor bracket 10-3 and shaft pin 10-9) to adapt to the removal of burrs from parts of different structures and sizes. Simultaneously, a closed working environment is formed inside the machine cover 2, allowing dust to be collected and preventing it from dispersing into the external air, thus improving the working environment and eliminating health hazards for workers.

[0035] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
