[0002] The processing of DC motors for water pumps involves some professional machining and motor technology. Generally speaking, the DC motors used in the manufacture of water pumps need to have certain power, speed and torque characteristics to meet the working requirements of the water pump. The rotor is the rotating part of the DC motor. The rotor rotates under the action of the magnetic field generated by the stator, thereby realizing the conversion of electrical energy into mechanical energy. At present, the production process of DC motor rotors, such as series-excited motor rotors, includes spot welding, cutting, and inspection processing steps.

[0027] The upper end bearing of the disc 4 is connected to an extrusion structure 7, which includes a motor 6 whose bearing is connected to the central top surface of the disc 4, a turntable 71 is provided at the output end of the motor 6, a bump 72 is provided on the surface of the turntable 71, a hollow plate 73 is sleeved on the surface of the bump 72, an extrusion rod 74 is provided at one end of the hollow plate 73, an extrusion plate 77 is provided at one end of the extrusion rod 74, a connecting plate 76 is provided at one end of the extension frame 81, a limit frame 75 is provided at one end of the connecting plate 76, and the extrusion rod 74 slides inside the limit frame 75 to facilitate driving the air blowing structure 8.

[0028] Another technical solution proposed by the present invention is to provide a method for processing a DC motor for a water pump, comprising the following steps: Step 1: Fix the rotor position: Place the rotor of the DC motor on the tray 11, ensure that the rotor is in close contact with the tray, accurately place the tray 11 on the placement plate 10 of the disc 4, so that the rotor is in the processing position, and use the spot welding head 12 to weld the rotor placed in the groove of the tray 11; Step 2: Start the drive mechanism: Start the motor 32 to start the drive rod 33 to move, and the drive rod 33 drives the half gear 34 to mesh with the driven wheel 35, so that the disc 4 starts to intermittently rotate a quarter of a turn to prepare for the subsequent processing steps; Step 3: Air blowing cleaning: The central bearing on the top of the disc 4 is connected to the motor 6, which drives the turntable 71 to rotate. The bump 72 on the turntable 71 moves around the circle, and the bump 72 slides inside the hollow plate 73, pushing the extrusion rod 74 to move back and forth. One end of the extrusion rod 74 applies pressure to the air bag 83 through the extrusion plate 77 to release gas, which enters the arc tube 88 through the one-way valve 2 87 connected to the outlet pipe 86 to clean the rotor surface. One-way air intake is achieved through the inlet pipe 84 and the one-way valve 1 85 to keep the rotor surface clean and improve product quality and production efficiency. Step 4: Discharging process: The rotation of the disc 4 drives the arc plate 91 to squeeze the push block 92, so that the accurate pushing and discharging of the tray 11 can be achieved through the coordinated action of the pull wire 93 and the push plate 911. Four sets of guide wheels are arranged in the middle of the pull wire 93 for fixed-point pulling. The guide wheels are connected to the push block 92 through the plate. When the disc 4 rotates to drive the arc plate 91 to squeeze the push block 92, the push block 92 drives the compression spring 94 to store force, and at the same time, the push plate 911 is stretched and stored by the tension spring 913. After the disc 4 rotates a quarter of a circle, the push block 92 resets and moves, the pull wire 93 is in a loose state, and the push plate 911 rebounds and stores force. Then, the cylinder 54 is driven by the external button to release the limit of the tray 11 of the clamping structure 5, and the tray 11 is further pushed onto the conveyor belt 2 to realize the discharging work.

[0029] Specifically, three sets of racks are arranged at equal intervals at the fixed end of the workbench 1, and a spot welding head 12, a turning head 13 and a detection head 14 are arranged at one end of each of the three sets of racks. The spot welding head 12, the turning head 13 and the detection head 14 respectively process the motor rotor in the tray 11 placed on the surface of the three sets of placement trays 10, and then the rotor of the DC motor is placed on the tray 11, and then the tray 11 is placed on the placement tray 10 directly below the spot welding head 12, and then the spot welding head 12 is started by an external button to weld the rotor on the tray 11; Thus, the weight of the tray 11 and the motor rotor presses the pressure plate 52 downward, the pressure plate 52 presses the rack 53 downward, the rack 53 presses the output end of the cylinder 54 at the bottom downward, the rack 53 meshes with the gear 55, the gear 55 drives the screw rods 56 at both ends to rotate, the two ends of the screw rod 56 are movably connected to the inner wall of the fixed shell 51, the surface of the screw rod 56 is threadedly connected with two groups of moving blocks 57, the two groups of moving blocks 57 move in opposite directions, the two groups of moving blocks 57 respectively drive the vertical plates 58 to move inside the notches 59, the placement tray 10 and the fixed shell 51 are provided with corresponding notches 59 on the surface, the two groups of vertical plates 58 respectively drive the two groups of clamping plates 510 to move The tray 11 is clamped and fixed in the middle, and a clamping structure 5 is provided on each set of placement plates 10 to fix the tray 11, and a cylinder 54 is provided at the bottom end of the rack 53. When the placement plate 10 rotates to one end close to the conveyor belt 2, it is necessary to discharge the material, and the two sets of clamping plates 510 need to be moved away from the two sides of the tray 11. The cylinder 54 under the corresponding rack 53 is driven by an external button, and the cylinder 54 drives the rack 53 to move upward, and the rack 53 is reversely meshed with the gear 55, and the gear 55 drives the screw 56 to rotate in the opposite direction, and the two sets of moving blocks 57 drive the clamping plates 510 connected to the vertical plates 58 to move in the opposite direction away from the surface of the tray 11; Then, the motor 32 fixed by the bottom block 31 at the top of the workbench 1 is started by an external button, and the motor 32 drives the driving rod 33 at the output end to rotate, and the driving rod 33 drives the half gear 34 to mesh with the driven wheel 35. The half gear 34 has six gear blocks symmetrically divided into two groups, and the driven wheel 35 is provided with eight gear blocks and four arc blocks, and two gear blocks are distributed between every two arc blocks, so that one group of gear blocks of the half gear 34 is engaged with the gear blocks of the driven wheel 35 to drive the disk 4 at the top of the driven rod 36 to rotate a quarter of a circle. When the disk 4 is directly below the spot welding head 12 and the other group of gear blocks of the half gear 34 contacts the arc blocks provided on the driven wheel 35, the driven rod 36 does not drive the disk 4 to rotate. With the continuous rotation of the motor 32, the intermittent rotation of the disk 4 is completed. The motion state of a quarter of a circle is completed, so that the four groups of placement disks 10 are rotated to the bottom of the processing head in turn to perform spot welding, turning and detection work, which is beneficial to improving processing quality and production efficiency. The motor 6 connected to the central bearing on the top surface of the disc 4 drives the turntable 71 at the output end to rotate, and the turntable 71 drives the protrusion 72 on the surface to rotate in a circle. The protrusion 72 slides from one end to the other end inside the hollow plate 73, so that the hollow plate 73 drives the extrusion rod 74 to slide back and forth inside the limit frame 75. The top of the limit frame 75 is connected and fixed to the extension frame 81 through the connecting plate 76. The extrusion rod 74 drives the extrusion plate 77 at one end to squeeze the airbag 83, and the spring 810 inside the airbag 83 is compressed. The two sides of the airbag 83 and the side away from the extrusion plate 77 are fixed with support plates 82. The support plate 82 is connected and fixed to the extension frame 81. After the airbag 83 is squeezed, the gas inside is output through the outlet pipe 86. The outlet pipe 86 is connected to a one-way valve 2 87 to output the gas to the inside of the arc tube 88. One end of the airbag 83 is connected to an inlet pipe 84. One end of the inlet pipe 84 is provided with a one-way valve 1 85. The length of the arc tube 88 is circular The circumference of the disk 4 is a quarter of a circle, and the surface of the arc tube 88 is evenly spaced with multiple groups of blowing heads 89. The multiple groups of blowing heads 89 are used to blow and clean the debris and dust on the rotor surface after turning. The arc tube 88 and the blowing head 89 are set between the turning head 13 and the detection head 14, so that when the rotor on the tray 11 after turning rotates a quarter of a circle on the disk 4, it is convenient to move from the turning head 13 to the movement trajectory below the detection head 14. The blowing head 89 cleans the debris and dust on the rotor surface during the movement. Since the extrusion plate 77 moves back and forth, when the extrusion plate 77 does not squeeze the airbag 83, the airbag 83 is reset by the internal spring 810. The one-way air intake work can be completed by the one-way valve 85 provided with the air intake pipe 84, so as to keep the rotor surface clean, improve product quality and production efficiency, ensure that the cleaning work on the rotor surface can be carried out at the appropriate position and time, and improve the cleaning effect. As the disc 4 rotates, the arc plate 91 on the surface is driven to rotate. Four groups of arc plates 91 are evenly spaced on the surface of the disc 4. The four groups of arc plates 91 are tilted outward from the center of the circle at the upper end of the disc 4. As the disc 4 rotates, the arc plate 91 is driven to rotate. The arc plate 91 squeezes the push block 92 outward. The push block 92 drives the T-shaped slide block 98 to slide outward in the T-shaped slide groove 97 opened inside the connecting shell 95. The connecting shell 95 is connected and fixed to the extension frame 81 through the connecting rod 96, so that the push block 92 drives the pull wire 93 connected to the left end to move. Four groups of guide wheels are set in the middle of the pull wire 93 for fixed-point pulling. The guide wheel is connected to the connecting shell through the plate 95 is connected, and the other end of the pull wire 93 drives the push plate 911 connected to the connecting block 910 to move away from the conveyor belt 2, so that the push block 92 squeezes the squeezing spring 99, and the connecting block 910 squeezes the squeezing spring 99. The opposite ends of the push block 92 and the connecting block 910 are respectively provided with a telescopic guide plate 915 to prevent the squeezing spring 99 from bending during the squeezing and stretching process. The push block 92 drives the compression spring 94 to pull and store force, and at the same time, the push plate 911 drives the tension spring 913 connected to the convex plates 912 at both ends to stretch and store force, and one end of the tension spring 913 is connected and fixed to the side plate of the conveyor belt 2 through the extension plate 914, and the tension spring 913 is higher than the height of the push plate 911. When the disc 4 rotates a quarter of a circle, the tray 11 placed on the surface of the disc 10 just below the detection head 14 rotates to one side of the push plate 911, which is on the same horizontal line as the conveyor belt 2, so as to facilitate automatic material pushing at the back. Therefore, when the disc 4 rotates a quarter of a circle, the arc plate 91 rotates a quarter of a circle to squeeze the push block 92. When the disc 4 rotates a quarter of a circle, a group of arc plates 91 rotates from one end close to the center of the disc 4 to the end away from the center of the circle. The arc plate 91 does not squeeze the push block 92. At this time, the push block 92 is reset to the left end by the compression spring 94, the pull wire 93 is in a loose state, and the push plate 911 is connected by the convex plates 912 on both sides. The tension spring 913 rebounds and accumulates force to move closer to the right end of the conveyor belt 2. Therefore, when the pallet 11 approaches the conveyor belt 2, the cylinder 54 is driven by the external button to release the limit of the pallet 11 on the clamping structure 5 on the placement plate 10 of a group close to the conveyor belt 2, and the push plate 911 is further pushed to push the pallet 11 onto the conveyor belt 2. Due to the transmission force on the surface of the conveyor belt 2, half of the pallet 11 is located on the conveyor belt 2 and can be discharged according to the transmission force. The pallet 11 can be accurately pushed and discharged, thereby improving production efficiency and reducing energy consumption to a certain extent. At the same time, the stability and reliability of the system are maintained, and it has certain operability and maintainability.
