Description

Technical Field

[0001] This utility model relates to the field of motor shaft processing technology, and in particular to a motor shaft end face de-screw machine. Background Technology

[0002] Motor shaft machining is a professional metal processing service involving the precision manufacturing and customization of motor shafts. The main processes include cutting, grinding, and customization of motor shafts to meet the precision, material, and size requirements of different motors. The machined motor shafts have high precision, high stability, and long service life, which can improve the performance and reliability of motors.

[0003] Currently, after the motor shaft core is processed by machine tools, the burrs and tail material on the end face of the shaft core need to be processed and removed by a separate machine and personnel. Manual processing is more troublesome and cannot process each shaft core well, cannot ensure the same precision, and is prone to customer complaints. Moreover, the machine tool processing can easily cause the shaft core to resonate, which may cause the shaft core to fly out, and in severe cases, it may cause the shaft core to break. Long-term processing will result in the ground being covered with shaft core waste, which is difficult to clean under the machine tool and will consume a lot of workers' time and energy.

Through mechanical processing, the shaft core can be guaranteed to have the same precision, and manual removal is no longer required, saving a lot of manpower. Furthermore, the fixing structure reduces the occurrence of resonance during the processing of the shaft core, preventing the shaft core from flying out or breaking.

[0015] 2. In this utility model, the reciprocating screw is driven by the motor to rotate, thereby driving the cleaning structure to reciprocate and clean the hard-to-reach areas on the underside of the machine tool. The water is also scraped off by the water pusher plate, which prevents water from accumulating for a long time and affecting the bottom of the machine tool. This eliminates the need for manual cleaning and saves workers' time and energy. Attached Figure Description

[0025] Reference Figures 1-8 A machine for removing nails from the end face of a motor shaft core, comprising:

[0026] A support frame 1 has a storage box 32 slidably connected to its side wall. A handle is fixedly connected to the side wall of the storage box 32, allowing it to be opened. A rotating shaft 2 is rotatably connected to the side wall of the support frame 1. A wheel 3 is fixedly sleeved on the outer side of the rotating shaft 2. Multiple notches are formed on the side wall of the wheel 3. A hydraulic rod 35 is fixedly installed on the upper side of the support frame 1. A push rod 36 is fixedly installed at the output end of the hydraulic rod 35. The push rod 36 matches the notches. When the notch in the wheel 3 moves to the corresponding position, the hydraulic rod 35 is activated, driving the push rod 36 forward, thus pushing the motor shaft core within the notch forward. A drive structure is installed on the support frame 1, including components fixedly mounted on the support frame. The control motor 18 is located on the lower side of the frame 1. The output shaft of the control motor 18 is fixedly mounted with a drive shaft 19. A spur gear 20 is fixedly sleeved on the outer side of the drive shaft 19. A spur gear 21 is fixedly sleeved on the outer side of the rotating shaft 2. The spur gear 20 and the spur gear 21 mesh with each other. A housing 16 is fixedly connected to the outer side of the wheel 3. Multiple sanding discs 17 are fixedly connected to the inner side of the housing 16. The push rod 36 pushes the shaft core to fit against the sanding disc 17, thereby completing the end face nail removal. A water spray shell 33 is fixedly connected to the upper side of the bracket 1. Multiple nozzles 34 are fixedly connected to the side wall of the water spray shell 33. The water spray shell 33 is connected to an external water pump to spray water on the wheel 3 and the sanding disc 17 for cooling treatment.

[0027] A fixing structure is installed on the bracket 1. The fixing structure includes a fixing block 4 installed on the side wall of the wheel 3. A fixing shaft 5 is fixedly connected to the side wall of the fixing block 4. A locking plate 6 is rotatably sleeved on the outside of the fixing shaft 5. A locking block 7 is fixedly connected to the side wall of the locking plate 6. A rotary spring 8 is fixedly connected between the locking plate 6 and the fixing block 4. A pressing rod 15 is fixedly connected to the upper side of the bracket 1. A groove is opened in the wheel 3. A pin 9 is slidably connected in the groove. A spring 10 is fixedly connected between the pin 9 and the groove. A hollow rod 11 is fixedly connected to the side wall of the pin 9. A sliding rod 12 is slidably connected in the hollow rod 11. A spring is fixedly connected between the sliding rod 12 and the hollow rod 11. Spring 13 and slider 12 are fixedly connected to one end of slider 37. A pressing block 14 is fixedly connected to the lower side of bracket 1. When pressing block 14 presses slider 37, the elastic force of spring 13 is much greater than that of spring 10, causing the pin 9 to move backward through slider 37. The pin 9 disengages from the locking block 7, and the locking plate 6 rebounds through the rotary spring 8, no longer fixing the shaft core, allowing the shaft core to fall off. The pin 9, which has moved to the bottom, can no longer move. At this time, pressing block 14 can press slider 37 through the inclined surface, causing slider 37 to move inward through spring 13 until it is freed from the pressing of pressing block 14.

[0028] A cleaning structure is installed on the bracket 1. The cleaning structure includes a rotating shaft 22 rotatably connected to the side wall of the bracket 1. The rotating shaft 22 is connected to the drive shaft 19 via a pulley assembly 23. The pulley assembly 23 consists of two pulleys and a belt. A reciprocating screw 24 is fixedly connected to the outside of the rotating shaft 22. Two fixed rods 25 are fixedly connected to the side wall of the bracket 1. A connecting plate 26 is slidably connected to the outside of the two fixed rods 25. A rotating shaft 27 is rotatably connected to the side wall of the connecting plate 26. A slider 28 is fixedly connected to the outside of the rotating shaft 27. The slider 28 matches the reciprocating screw 24 and moves in the groove outside the reciprocating screw 24 to complete the reciprocating motion. A connecting plate 29 is fixedly connected to the lower side of the connecting plate 26. Multiple brush plates 30 and a water pusher plate 31 are fixedly connected to the lower side of the connecting plate 29.

[0029] In this invention, the operator first places the motor shaft into the recess of the wheel 3 using an external placement device. Then, by turning on the control motor 18, the drive shaft 19 rotates. The drive shaft 19, through spur gear 20 and spur gear 21, drives the rotating shaft 2 to rotate, which in turn drives the wheel 3 to rotate. During rotation, the wheel 3 drives the outer fixing structure to rotate. During this rotation, the clamping plate 6 is pressed downwards by the pressing rod 15, causing the clamping block 7 to press the pin 9 against the inclined surface. When it reaches the fixed position, the pin 9 rebounds through the spring 10, locking it into the clamping block 7, thus fixing the motor shaft. When it moves to the lower side, the pressing block 14 presses the slider 37, compressing the spring 10 while simultaneously compressing the spring 2 13. This causes the sliding rod 12 and hollow rod 11 to move the pin 9 backwards and to the left, making it unable to hold the clamping block 7. The clamping plate 6 then springs open under the force of the return spring 8, no longer clamping the motor shaft. The core is fixed, allowing the shaft core to fall off. The pin 9, which has moved to the bottom, can no longer move. At this time, the pressing block 14 can press the slider 37 through the inclined surface, causing the slider 37 to move inward through the spring 13 until it is freed from the pressing block 14. The fixing structure reduces the resonance of the shaft core during processing, preventing the shaft core from flying out or breaking. At the same time, the drive shaft 19 can also drive the rotating shaft 22 to rotate through the pulley assembly 23. The rotating shaft 22 drives the reciprocating screw 24 to rotate, and then through the sliding groove on the side wall of the reciprocating screw 24, the connecting plate 26 moves back and forth outside the fixed rod 25 through the slider 28. This, in turn, drives the brush plate 30 and the water pusher plate 31 to move back and forth, cleaning the hard-to-reach areas on the bottom of the machine tool. The water pusher plate 31 scrapes out the water falling from above, preventing water accumulation from affecting the bottom of the machine tool and eliminating the need for manual cleaning.
