Description

Technical Field

[0001] The invention relates to a motor processing device, in particular to a fully automatic worm thread rolling device for a micro motor. Background Art

[0002] During the processing of the motor output shaft, its surface is generally subjected to a worm thread rolling operation. Woven thread rolling is essentially the surface extrusion of the output shaft to press out threads on its surface. The external thread processing of the output shaft usually uses worm thread rolling equipment. The existing thread rolling equipment generally places the motor in the processing position manually and uses double rollers to extrude the motor output shaft. This loading method has great safety hazards and is prone to danger. In addition, the fixture of this thread rolling equipment has poor positioning ability for the motor output shaft, and it is easy to loosen and deviate during the thread rolling process, which increases the deformation of the motor shaft and affects the thread rolling effect. In addition, manual positioning is usually used to position the processed motor to adjust the motor rotation to a position suitable for subsequent production. This processing method is time-consuming and labor-intensive, prolongs the production cycle, increases production costs, is very inconvenient to use, and has poor practicality.

[0075] In order to facilitate the description of the action process of this technical solution, Figure 1 The device angle shown is used as the direction reference for the following specific action description. It can be seen that the workbench 3 is located at the rear of the frame 2, the positioning mechanism 6 is arranged on the right side of the positioning mechanism 4, and the feeding rail 8 is arranged on the right side of the positioning mechanism 6. The clamping assembly 95 of the single-station material picking assembly 89 is defined as the first material picking station. In this figure, the clamping assembly 95 on the right side of the multi-station material picking assembly 88 is defined as the second material picking station, and the clamping assembly 95 on the left side of the multi-station material picking assembly 88 is defined as the third material picking station. In this figure, the cavity on the left side of the positioning mechanism 6 for placing the micro motor is the first cavity 81, and the cavity on the right side for placing the micro motor is the second cavity 82. In the specific production process, the following steps are included:

[0076] First, the driving device 26 on the support frame 25 drives the material taking device 28 to move to the position of the unloading motor, and the servo motor 97 on the driving device 26 drives the synchronous wheel 98 to rotate, so that the synchronous belt 99 on the synchronous wheel 98 drives the multi-station material taking component 88 and the single-station material taking component 89 to move rightward on the transverse guide rail 27. At this time, the first material taking station of the single-station material taking component 89 moves to the top of the feeding rail 8, and the third material taking station on the multi-station material taking component 88 moves to the second cavity 82 on the positioning mechanism 6. When it moves to the target position, the driving cylinder 104 in the multi-station material picking assembly 88 and the single-station material picking assembly 89 is started, and the driving cylinder 104 drives the sliding plate 101 to slide downward along the longitudinal guide rail 103 on the assembly plate 100, so that the first assembly plate 90 and the second assembly plate 91 located on the sliding plate 101 slide to the position of clamping the micro motor respectively, so that the clamping assemblies 95 on the first material picking station and the third material picking station clamp the micro motors on the feeding rail 8 and the second cavity 82 respectively.

[0077] Then, after the first material picking station and the third material picking station have clamped the micro-motor, the servo motor 97 drives the synchronous wheel 98 to rotate, so that the synchronous belt 99 on the synchronous wheel 98 drives the multi-station material picking assembly 88 and the single-station material picking assembly 89 to move leftward on the transverse guide rail 27, so that the first material picking station on the single-station material picking assembly 89 moves to above the second cavity 82 of the positioning mechanism 6, and the second material picking station on the multi-station material picking assembly 88 moves to above the material trough 56 of the positioning mechanism 4, and the third material picking station moves to one side of the positioning mechanism 4. After reaching the target position, the driving cylinder 104 is started again to move the first group The mounting plate 90 and the second assembly plate 91 descend along the longitudinal guide rail 103, thereby driving the first material picking station and the second material picking station to descend. Then, the clamping claw 110 on the first material picking station places the micro motor in the second cavity 82 that has been emptied of the positioning mechanism 6, and the clamping claw 110 on the second material picking station synchronously descends to the material trough 56 to take out the micro motor that has completed the rolling thread processing in the loading rail 54. Then, the first assembly plate 90 and the second assembly plate 91 rise along the longitudinal guide rail 103 driven by the driving cylinder 104, so that the first material picking station and the second material picking station rise from the positioning mechanism 4 and the positioning mechanism 6.

[0078] Then, when the first material picking station and the second material picking station complete the micro-motor picking and unloading operations and rise, the sliding cylinder on the positioning mechanism 6 is started, and the fixing frame 14 is driven to move to the right on the slide rail 16 through the connecting block 115, so that the first cavity 81 on the positioning mechanism 6 moves to the bottom of the first material picking station. At the same time, the adjusting cylinder 92 on the first assembly plate 90 is started, and the cylinder shaft in the adjusting cylinder 92 drives the adjusting plate 93 to slide and adjust in the guide groove 105, so that the adjusting plate 93 slides along the guide groove 84 to the right side of the first assembly plate 90, so that the third material picking station on the multi-station material picking assembly 88 is moved to above the material groove 56 of the positioning mechanism 4. Since the direction of the micro-motor on the positioning mechanism 6 is different from that of the micro-motor in the positioning mechanism 4, at this time, the rotating cylinder 94 on the second material picking station and the third material picking station is started, and the micro-motor on its clamping assembly 95 is rotated to the appropriate direction respectively, so that the clamping jaw 110 on the clamping assembly 95 can achieve rotation adjustment at different angles.

[0079] Furthermore, the first assembly plate 90 and the second assembly plate 91, driven by the driving cylinder 104, drive the first material picking station and the third material picking station to perform the descending operation again, and the micro motor that has completed the worm thread rolling process in the first cavity 81 of the positioning mechanism 6 is taken out through the clamping claw 110 on the first material picking station. At the same time, the third material picking station places the micro motor on its clamping claw 110 in the material trough 56 of the loading rail 54 to wait for the worm thread rolling operation. After completing the unloading operation, the first assembly plate 90 and the second assembly plate 91 are driven by the driving cylinder 104 to rise along the longitudinal guide rail 103, thereby driving the first material picking station and the third material picking station to complete the ascending action.

[0080] Furthermore, when the third material picking station places the micro motor in the material slot 56 of the positioning mechanism 4 and lifts it up, the adjusting cylinder 92 on the first assembly plate 90 is started again, and the adjusting plate 93 is pulled back in the opposite direction through the cylinder shaft, so that the adjusting plate 93 slides along the guide groove 84 to the left side of the first assembly plate 90. After completing this action, the servo motor 97 on the drive device 26 is started, and the multi-station material picking assembly 88 and the single-station material picking assembly 89 slide to the right on the transverse guide rail 27 driven by the synchronous wheel 98 and the synchronous belt 99, so that the single-station material picking assembly 89 The first material-retrieving station on the multi-station material-retrieving assembly 88 moves to the top of the feeding rail 8, and the second material-retrieving station on the multi-station material-retrieving assembly 88 moves to the top of the first cavity 81 of the positioning mechanism 6. After reaching the target position, the driving cylinder 104 is started to make the first assembly plate 90 and the second assembly plate 91 descend along the longitudinal guide rail 103, thereby driving the first material-retrieving station and the second material-retrieving station to achieve synchronous descent. After descent, the clamping jaw 110 on the first material-retrieving station puts the micro-motor that has completed the rolling of the worm teeth back into the feeding rail 8. At the same time, the clamping jaw 110 on the second material-retrieving station 0 The micro motor that has completed the rolling of the worm teeth is placed in the first cavity 81 to wait for the positioning operation. After that, the driving cylinder 104 is started again to drive the first assembly plate 90 and the second assembly plate 91 to rise along the longitudinal guide rail 103. Then, the adjusting cylinder 92 on the first assembly plate 90 is started again, and the adjusting plate 93 is slid along the guide groove 84 to the right side of the first assembly plate 90 through the cylinder shaft, and the feeding rail 8 sends out the micro motor that has completed the processing, and then sends the micro motor to be processed to the bottom of the first material picking station. The sliding cylinder on the positioning mechanism 6 is started, and the fixing frame 14 is driven to move to the left on the slide rail 16 through the connecting block 115, so that the first cavity 81 moves to the bottom of the rotating component 24, and the rotating component 24 performs a positioning operation on the micro motor that completes the worm gear rolling in the first cavity 81. At the same time, with the sliding of the fixing frame 14, the second cavity 82 on the positioning mechanism 6 where the micro motor to be processed is placed is synchronously moved to the bottom of the third material picking mechanism to wait for the third material picking mechanism to pick up the material. At this point, the entire production process is completed. Automatic loading and unloading process.

[0081] Furthermore, during the processing of rolling the worm teeth, the workpiece is first inspected, and the carrier rail 54 is inspected by the sensor on the guide plate 46 to confirm whether the motor to be processed on the carrier rail 54 is in place for subsequent processing.

[0082] Then, the pushing of the motor is realized through the pushing assembly 11. When the sensor detects that the motor is in place, the pushing cylinder 48 is started, and the transmission block 55 is pushed toward the working chamber through the transmission shaft. At this time, the pushing shaft 60 on the transmission block 55 moves toward the direction of the motor, so that the end of the motor output shaft 114 is inserted into the second sleeve 61 in the pushing shaft 60, and the transmission block 55 pushes the loading rail 54 carrying the motor to the oil baffle 50.

[0083] Next, the motor output shaft 114 is positioned through the positioning assembly 12. When the motor is pushed to the oil baffle plate 50, the output shaft 114 at the front end of the motor passes through the guide hole 77 on the oil baffle plate 50 and extends into the working chamber for rolling, and the front end portion of the output shaft 114 is synchronously inserted into the first sleeve 40 in the bearing 39. At this time, the two ends of the motor output shaft 114 are positioned by the first sleeve 40 and the second sleeve 61 respectively. At the same time, the ejection cylinder 53 is started, and the driving shaft pushes the positioning rod 52 toward the motor direction through the push block 78, so that the positioning rod 52 is coaxially abutted against the output shaft 114 in the first sleeve 40 to achieve axial positioning of the motor output shaft 114 and prevent axial displacement of the output shaft 114.

[0084] Furthermore, the rollers 5 located on both sides of the rotating seat 10 perform rolling processing on the motor output shaft 114. The two rollers 5 are inserted into the working cavity, and the roller 5 on one side presses against the motor output shaft 114, thereby squeezing the motor output shaft 114 toward the other rolling position. When the rollers 5 press against the motor output shaft 114, the rotating seat 10 rotates and deflects at a certain angle along the extrusion direction under the action of the mounting shaft, thereby effectively protecting the motor output shaft 114.

[0085] Finally, after the thread rolling is completed, the roller 5 is released from the motor output shaft 114, and the rotating shaft 36 rotates to the starting state under the action of the reset tension spring 42 to complete the reset. At this time, the ejection cylinder 53 is started, the drive shaft retracts, and the push block 78 is released from the positioning rod 52. The positioning rod 52 is reset to the starting state under the action of the reset spring. At the same time, the pushing cylinder 48 pulls the transmission block 55 back along the slide rail 16 in the opposite direction through the transmission shaft. During the sliding process, the transmission block 55 pulls the loading rail 54 back to the starting position through the pull rod 58. When reaching the starting position, the loading rail 54 will further slide toward the transmission block 55 under the inertia state, so that the end of the motor output shaft 114 is again stuck in the second shaft sleeve 61, affecting the removal of the motor. In order to avoid the above situation, a buffer spring 59 is set on the pull rod 58, so that the loading rail 54 can be pushed out of the limit by the buffer spring 59 after the reset movement to prevent the return from getting stuck. At this point, the positioning thread rolling process of the entire motor output shaft 114 is completed.

[0086] Furthermore, when performing the positioning operation, the micromotor after the worm gear rolling is placed in the second cavity 82, and the output shafts 114 at both ends of the micromotor are respectively inserted into the limit grooves 83 at the top of the first support block 18 and the second support block 19. At this time, the positioning block 22 is pressed against the bottom of the shell of the micromotor under the action of the telescopic spring 70. When the material sensor 87 detects that a micromotor is placed in the accommodating cavity 20, the lifting cylinder 75 is started, and the lifting cylinder 75 pulls the transmission block 55, and the rotating arm 72 is rotated and swung downward from the fixed arm 71 through the transmission block 55, so that the driving belt 116 of the rotating arm 72 is pressed against the top of the micromotor. On the outer shell, the driving motor 73 is started, so that the pulley 74 drives the driving belt 116 to rotate. During the rotation process, the driving belt 116 drives the micro motor to perform synchronous rotation movement in the second cavity 82. When the micro motor rotates to the target position, the positioning block 22 is inserted into the positioning hole 38 on the motor housing under the action of the telescopic spring 70, thereby fixing the micro motor at this position to achieve the positioning of the micro motor. After the positioning is completed, the lifting cylinder 75 is started again, and the rotating arm 72 is driven to rotate and swing upward through the pulling block 76, so that the driving belt 116 leaves the micro motor, and the positioned micro motor can be taken out for subsequent processing.

Technical personnel in this industry can make some deformation and modifications under the inspiration of this technical solution.
