Description

Technical Field

[0001] This invention relates to the field of rapid prototyping devices for molds, and more particularly to a rapid prototyping device and method for a submersible pump mold. Background Technology

[0002] As a core conveying equipment in fields such as water conservancy, mining, and municipal engineering, the molding accuracy and processing efficiency of the molds used in submersible pumps directly determine the assembly accuracy and service life of the pumps. Existing devices typically mount the detection components on both ends of the frame using support rods. Splashing debris can damage the lens of the detection equipment, shorten the lifespan of the detection components, and increase equipment maintenance costs. At the same time, metal shavings generated during processing usually adhere to the gaps inside the T-slot worktable, making them difficult to remove and causing inconvenience for workers to clean. To address these issues, this application presents a rapid prototyping device and method for submersible pump molds. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid prototyping device and method for submersible pump molds.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rapid prototyping device for a submersible pump mold, comprising a base, the base being U-shaped, a gantry frame sliding on both sides of the top surface of the base via an X-axis linear motor, a Y-axis linear motor mounted on the upper end of the gantry frame, a vertically sliding Z-axis linear motor fixedly connected to the slider of the Y-axis linear motor, a rotary motor fixedly connected to the slider of the Z-axis linear motor, a mounting plate fixedly connected to the rotating shaft of the rotary motor, a horizontal plate fixedly connected to the middle section of the outer wall of the mounting plate, a drive motor mounted on the top surface of the horizontal plate, a rapid tool change mechanism provided on the bottom surface of the horizontal plate, the output shaft of the drive motor passing through the horizontal plate and being connected to the internal rotating shaft of the rapid tool change mechanism, a detachable milling cutter inserted into the rapid tool change mechanism, a tool changer provided at one end of the base, a tool changer holder having multiple tapered tubes for inserting tools equidistantly on the top surface of the tool changer holder, a positioning component for positioning materials provided in the middle of the top surface of the base, and multiple detection components for detecting material processing equidistantly provided on the upper ends of the inner walls on both sides of the base.

[0005] Preferably, the positioning component includes a processing plate fixed to the top surface of the machine base. The processing plate is hollow inside, and a plurality of internal threaded holes are evenly opened on the top surface of the processing plate. Positioning pins are screwed into the internal threaded holes.

[0006] Preferably, the processing plate has multiple through holes equidistantly opened on both sides of the outer wall of the machine base, and a filter plate is rotatably installed in the through holes. One end of the filter plate is coaxially fixed to a wind turbine impeller rotatably installed in the through hole.

[0007] Preferably, the outer walls on both sides of the base are provided with connecting pipes that communicate with multiple through holes. The connecting pipes are U-shaped in general. A vacuum fan is provided at one end of the base. The output end of the vacuum fan is connected and fixed to the middle section of the connecting pipe.

[0008] Preferably, the bottom surface of the processing plate is inclined, and an opening is provided at the lower end of the inclined surface. A sealing plate is fixed to the end of the processing plate at the opening by bolts. The sealing plate has an inverted L-shaped cross section, and a sealing rubber gasket that extends into the interior of the processing plate through the opening is fixed to one end face of the sealing plate.

[0009] Preferably, the detection component includes mounting slots equidistantly formed on the upper ends of the inner walls on both sides of the base. A rotating rod is rotatably mounted in the mounting slot. A fixing box is fixedly connected to the outer wall of the rotating rod. Multiple spring-locking steel balls are equidistantly arranged on the inner walls on both sides of the fixing box. A detection component, which is a 3D scanner or an industrial camera, is detachably inserted into the fixing box. Both outer walls of the 3D scanner and the industrial camera have locking slots adapted to the spring-locking steel balls. A gear transmission box is provided on one inner wall of the mounting slot. Two meshing gears are provided in the gear transmission box. One end of the rotating rod is coaxially fixedly connected to one of the two gears. The other gear is coaxially fixedly connected to the output end of a worm gear transmission box. The input end of the worm gear transmission box is coaxially fixedly connected to a first motor mounted on the outer wall of the base. A wire groove communicating with the mounting slot is formed on the outer wall of the base. A control box is provided on the outer wall of one end of the base.

[0010] Preferably, an explosion-proof glass plate is bolted to the outer wall of the base at the mounting groove.

[0011] This invention also proposes a method for using a rapid prototyping device for submersible pump molds, comprising the following steps: S1: First, power is supplied to all electrical appliances and motors. Then, the required milling cutters are inserted into the tapered tubes on the top of the tool changer to pre-store the tools. Based on the processing and inspection requirements of the submersible pump mold material, suitable inspection components are selected. Using a 3D scanner or industrial camera, the inspection components are inserted into the fixing box. The spring-locking steel balls on both sides of the fixing box cooperate with the locking grooves on the outer wall of the inspection components to quickly fix the inspection components. Then, the first motor is started, and the rotating rod is driven to rotate through the meshing of the gears in the worm gear transmission box and the gear transmission box. This adjusts the inspection angle of the inspection components in the fixing box. The angle of the inspection components is observed through the explosion-proof glass plate until it is adjusted to the preset inspection position to ensure accurate subsequent processing and inspection. The detachable design of the inspection components allows the device to adapt to different types of inspection requirements, improving the applicability of the device.

[0012] S2. Next, take the submersible pump mold material with pre-drilled positioning holes on the bottom surface from the storage area and place it on the top surface of the processing plate. According to the positioning requirements of the material, screw the positioning pin into the corresponding internal threaded hole on the top surface of the processing plate, and make the positioning pin accurately inserted into the positioning hole on the bottom surface of the material. The positioning pin and the positioning hole cooperate to limit and fix the material, preventing the material from shifting during processing. At the same time, check the installation status of the sealing plate to ensure that the sealing rubber gasket on the sealing plate is tightly attached to the opening inside the processing plate, ensuring the sealing of the inside of the processing plate. The positioning pin can improve the positioning accuracy of the material during processing, and the sealing plate can prevent processing debris from entering the inside of the processing plate and becoming impossible to clean.

[0013] S3. Then, start the vacuum fan at one end of the base. The vacuum fan generates suction force, which draws air through the through holes on both sides of the processing plate through the connecting pipe. The airflow drives the impeller inside the through hole to rotate, and the impeller drives the coaxially fixed filter plate to rotate synchronously, starting the filter plate in advance to prepare for the filtration of processing debris. Start the X-axis linear motor, Y-axis linear motor and Z-axis linear motor through the control box, adjust the position of the gantry and the rotary motor, so that the quick tool change mechanism moves above the tool changer. Start the drive motor, which drives the internal shaft of the quick tool change mechanism to rotate, so that the quick tool change mechanism grabs the preset milling cutter on the tool changer and completes the quick installation of the milling cutter. The quick tool change mechanism enables the rapid replacement of milling cutters and improves the processing efficiency of the device.

[0014] S4. Next, the rotary motor and drive motor are started. The rotary motor drives the mounting plate to rotate, thereby adjusting the machining angle of the milling cutter. The drive motor drives the milling cutter to rotate at high speed. Through the coordinated action of the X-axis linear motor, Y-axis linear motor, and Z-axis linear motor, the milling cutter performs all-round rapid forming processing on the material. During the processing, the detection component is in real-time working state. A 3D scanner or industrial camera performs real-time detection on the material processing surface. The detection data is transmitted to the control box through the wiring in the cable tray. If a processing deviation is detected, the control box automatically adjusts the operating parameters of each linear motor and rotary motor to ensure the material processing accuracy. The debris generated during processing falls to the top surface of the processing plate. Under the suction force of the vacuum fan, the debris is sucked into the through hole, filtered by the filter plate, and left inside the processing plate. The filtered airflow is extracted and discharged through the connecting pipe. Through the cooperation of the filter plate and the wind impeller, the wind impeller drives the filter plate to rotate synchronously. Using centrifugal force, the debris attached to the filter plate is thrown into the processing plate.

[0015] S5. Finally, after the material processing is completed, first turn off all motors and the vacuum fan. Control the X-axis, Y-axis, and Z-axis linear motors through the control box to move the quick tool changer to the top of the tool changer. Start the drive motor to move the quick tool changer back into the corresponding tapered tube of the tool changer, completing the milling cutter reset. Then, take out the finished submersible pump mold, unscrew the positioning pin on the processing plate, unscrew the bolts on the sealing plate, open the sealing plate, and use the inclined surface of the bottom of the processing plate to clean the processing debris collected inside. After cleaning, reinstall the sealing plate and tighten the bolts, then turn off the main power. The use of the device is now complete.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the cooperation between the fixing box and the spring-locking steel ball facilitates the quick assembly and disassembly of the detection component. At the same time, the cooperation between the first motor, the worm gear transmission box and the rotating rod facilitates the flexible adjustment of the detection angle of the detection component. Furthermore, the cooperation between the mounting groove and the explosion-proof glass plate effectively blocks flying debris, protects the lens of the detection equipment, extends the service life of the detection component, and reduces equipment maintenance costs. Thus, it can achieve the functions of convenient adaptation of the detection component, accurate detection and not easily damaged. In addition, the cooperation between the vacuum fan and the connecting pipe generates a stable suction force. Combined with the rotation of the impeller and the filter plate, centrifugal force is used to throw the attached debris into the processing plate, which facilitates the quick cleaning of processing debris, avoids debris adhering to the gaps of the table, reduces the difficulty of cleaning for workers, and improves the chip removal efficiency. Thus, it can achieve the functions of a clean processing environment and convenient debris cleaning. Finally, it solves the problems of the detection component being easily damaged by debris and the processing debris adhering to the table and being inconvenient to clean in the existing device, and improves the ease of use, detection stability and chip removal efficiency of the device.

Multiple spring-locking steel balls 20 are equidistantly arranged on the inner walls on both sides of the fixing box 19. A detection component, which is a 3D scanner 21 or an industrial camera, is detachably inserted into the fixing box 19.

The above features combine to improve the detection protection structure of the device, ensuring the normal operation of the detection component.

[0023] Working principle: In this embodiment, the present invention also proposes a method for using a rapid prototyping device for submersible pump molds, including the following steps: Step 1: Place the mold material with pre-drilled positioning holes on the processing plate 10. Use the positioning pin 12 and the internal threaded hole 11 to insert the positioning pin 12 into the positioning hole of the material to achieve stable fixation of the material and prevent displacement during processing, thus laying the foundation for precise processing. At the same time, check the fit between the sealing plate 17 and the sealing rubber gasket to ensure the internal sealing of the processing plate 10 and prevent debris from falling. Step two: Then, the 3D scanner 21 or industrial camera is inserted into the fixing box 19. The spring locking steel ball 20 and the locking groove are used to quickly fix the detection part. The first motor is started. Through the meshing of the worm gear transmission box and the gear transmission box, the rotating rod 18 is driven to rotate. The detection angle of the detection part is adjusted. The angle is confirmed to be in place by observing through the explosion-proof glass plate 23. This ensures that the detection part can be accurately detected throughout the entire processing process. At the same time, the explosion-proof glass plate 23 can block flying debris and protect the detection lens. Step 3: Utilize the tapered tube on the tool changer 9 to store various milling cutters 8. Adjust the position of the gantry 2 and the quick tool changer 7 using the coordinated X-axis linear motor, Y-axis linear motor, and Z-axis linear motor 3. Start the drive motor 6 to activate the quick tool changer 7, which picks up the preset milling cutter 8 from the tool changer 9 and completes its installation. Simultaneously, start the rotation motor 4 to rotate the mounting plate 5, adjusting the milling cutter 8 to a suitable machining angle to prepare for subsequent machining. Step four: Start the drive motor 6 to drive the milling cutter 8 to rotate at high speed. With the coordinated action of the X-axis linear motor, Y-axis linear motor and Z-axis linear motor 3, the material is rapidly formed in all directions. During the processing, the detection component works in real time. The detection data is transmitted to the control box 22 through the wire groove to realize real-time feedback and adjustment of processing deviation. At the same time, the vacuum fan 16 starts to generate suction force. Through the connecting pipe 15, air is drawn from the through holes on both sides of the processing plate 10. The debris generated during processing is sucked to the through holes under the action of suction force. After being filtered by the filter plate 13, it falls into the interior of the processing plate 10. The filter plate 13 rotates synchronously under the drive of the wind impeller 14. The centrifugal force generated by it can throw off the debris attached to its surface and prevent the filter plate 13 from being blocked. Step 5: After the mold processing is completed, first turn off the vacuum blower 16 and all motors. After the equipment has completely stopped, unscrew the bolts on the sealing plate 17, remove the sealing plate 17 and its sealing rubber gasket. Utilize the inclined structure of the inner bottom surface of the processing plate 10 to allow the debris collected inside to converge towards the opening under gravity. Then, use manual or special cleaning tools to thoroughly clean the debris inside the processing plate 10 from the opening. After cleaning, attach the sealing rubber gasket to the opening of the processing plate 10, reinstall the sealing plate 17 and tighten the bolts to ensure the internal sealing of the processing plate 10. The use of the device is now complete.

Then, insert the milling cutter (8) to be used into the tapered tube on the top surface of the tool changer (9) to complete the pre-storage of the tool. According to the processing and inspection requirements of the submersible pump mold material, select the appropriate inspection component and use a 3D scanner (21) or industrial camera to insert the inspection component into the fixed box (19). Use the spring locking steel balls (20) on both sides of the fixed box (19) to cooperate with the locking groove on the outer wall of the inspection component to achieve rapid fixation of the inspection component. Then, start the first motor and drive the rotating rod (18) to rotate through the gear meshing transmission in the worm gear transmission box and the gear transmission box. Then, adjust the inspection angle of the inspection component in the fixed box (19). Observe the angle status of the inspection component through the explosion-proof glass plate (23) until it is adjusted to the preset inspection position to ensure the accuracy of subsequent processing and inspection. S2, then take the submersible pump mold material with pre-drilled positioning holes on the bottom surface from the storage area and place it on the top surface of the processing plate (10). According to the positioning requirements of the material, screw the positioning pin (12) into the corresponding internal thread hole (11) on the top surface of the processing plate (10) and make the positioning pin (12) accurately inserted into the positioning hole on the bottom surface of the material. The material is limited and fixed by the cooperation of the positioning pin (12) and the positioning hole to prevent the material from shifting during the processing. At the same time, check the installation status of the sealing plate (17) to ensure that the sealing rubber gasket on the sealing plate (17) fits tightly against the opening inside the processing plate (10) to ensure the sealing of the inside of the processing plate (10). S3, then start the vacuum fan (16) at one end of the base (1). The vacuum fan (16) generates suction force, and through the connecting pipe (15), it draws air from the through holes on both sides of the processing plate (10). The airflow drives the wind impeller (14) in the through hole to rotate. The wind impeller (14) drives the coaxially fixed filter plate (13) to rotate synchronously, starting the filter plate (13) in advance to prepare for the filtration of subsequent processing debris. Start the X-axis linear motor and Y-axis linear motor through the control box (22). Linear motor and Z-axis linear motor (3), adjust the position of gantry (2) and rotary motor (4) to move the quick tool change mechanism (7) above the tool changer (9), start drive motor (6), drive motor (6) drives the internal shaft of quick tool change mechanism (7) to rotate, so that quick tool change mechanism (7) grabs the preset milling cutter (8) on tool changer (9) and completes the quick installation of milling cutter (8). Through the setting of quick tool change mechanism (7), the quick replacement of milling cutter (8) can be realized; S4, then start the rotary motor (4) and drive motor (6). The rotary motor (4) drives the mounting plate (5) to rotate, thereby adjusting the machining angle of the milling cutter (8). The drive motor (6) drives the milling cutter (8) to rotate at high speed. Through the coordinated action of the X-axis linear motor, Y-axis linear motor, and Z-axis linear motor (3), the milling cutter (8) is driven to perform all-round rapid forming processing on the material. During the processing, the detection component is in real time working. The 3D scanner (21) or industrial camera performs real-time detection on the material processing surface. The detection data is transmitted to the control box (22) through the wire in the wire groove. If the processing is detected, the control box will detect the material processing surface. Deviation, the control box (22) automatically adjusts the operating parameters of each linear motor and rotary motor (4) to ensure the material processing accuracy; the debris generated during processing falls to the top surface of the processing plate (10), and under the suction force of the vacuum blower (16), the debris is sucked into the through hole, filtered by the filter plate (13) and left inside the processing plate (10), and the filtered airflow is extracted and discharged through the connecting pipe (15). Through the cooperation of the filter plate (13) and the wind impeller (14), the wind impeller (14) drives the filter plate (13) to rotate synchronously, and uses centrifugal force to throw the debris attached to the filter plate (13) into the processing plate (10); S5. Finally, after the material processing is completed, first turn off all motors and vacuum blowers (16), and control the X-axis, Y-axis and Z-axis linear motors to work together through the control box (22) to drive the quick tool change mechanism (7) to move above the tool changer (9), start the drive motor (6) to drive the quick tool change mechanism (7) to move, and put the milling cutter (8) back into the corresponding tapered tube of the tool changer (9) to complete the reset of the milling cutter (8); then take out the finished submersible pump mold, then unscrew the positioning pin (12) on the processing plate (10), unscrew the bolts on the sealing plate (17), open the sealing plate (17), and use the inclined surface of the bottom of the processing plate (10) to clean the processing debris collected inside the filter. After cleaning, reinstall the sealing plate (17) and tighten the bolts, turn off the main power, and the use of the device is completed.
