[0002] CNC gear hobbing machine is the most widely used type of gear processing machine tool. It mainly uses hobs to process spur and helical cylindrical gears according to the development method. It can also process worm gears, sprockets, etc. When the gear hobbing machine processes the gear, it is usually equipped with coolant, which is used to spray coolant on the cut gear and flush the waste chips generated by gear cutting.

[0003] However, in the existing arrangement, when the waste chips are flushed away by the coolant, 1. some of the waste chips and coolant will fall on the surface of the workpiece placement table below. At the same time, because the placement table will rotate during the workpiece processing, the waste chips and coolant falling on its surface will be rotated and splashed to various parts of the machine, making it more difficult, time-consuming and labor-intensive for the staff to clean the machine later, affecting the overall work efficiency; 2. Although the existing equipment generally has a recycling and reuse mechanism to recycle the coolant and reduce resource loss, during the long processing process, the filter plate inside the recovery device is prone to clogging after accumulating a lot of waste chips, affecting the filtration efficiency, requiring the staff to stop the machine for cleaning, which has certain limitations.

[0032] Please refer to Figure 1 - Fig. 9 As shown in the figure, an automatic cleaning device for a numerical control hobbing machine includes a base 1. The base 1 is designed to be hollow so that coolant can be stored in its interior in advance, facilitating the use of the device. Baffles 2 are provided around the upper surface of the base 1.

Among them, the right end of the impurity falling opening 14 is located below the left end of the clamping mechanism 4, so that most of the waste chips and coolant generated during the processing can directly fall into the interior of the base 1 from the impurity falling opening 14;

[0033] The cleaning mechanism 15 includes a first rotating rod 501, and the first rotating rod 501 is rotatably installed inside the upper end of the base 1. A rotating spur gear 502 is provided on the circumferential surface of the upper end of the first rotating rod 501.

The front end of the first driven spur gear 503 is meshed and connected with a second driven spur gear 504. A second rotating rod 505 is provided in the middle of the upper surface of the second driven spur gear 504. The upper end of the second rotating rod 505 penetrates through the base 1 and is fixedly connected with a cleaning brush 506. Through the setting of the first driven spur gear 503, the rotating directions of the rotating spur gear 502 and the cleaning brush 506 are the same, that is, both rotate counterclockwise, so that the cleaning brush 506 can sweep the waste chips to the left to the impurity falling port 14;

[0034] The clamping mechanism 4 includes a U-shaped fixed seat 401, and the U-shaped fixed seat 401 is arranged on the right side of the upper surface of the base 1. A first movable groove 12 is opened inside the lower end of the U-shaped fixed seat 401. The rotating spur gear 502, the first driven spur gear 503 and the second driven spur gear 504 are all arranged inside the first movable groove 12. The setting of the first movable groove 12 provides a rotating space for the rotating spur gear 502, the first driven spur gear 503 and the second driven spur gear 504, so that when the rotating spur gear 502 rotates, it can smoothly drive the first driven spur gear 503 and the second driven spur gear 504 to rotate. Among them, the lower end of the first driven spur gear 503 is rotatably installed inside the U-shaped fixed seat 401 through a positioning shaft. A placing table 402 is rotatably installed on the lower surface of the U-shaped fixed seat 401. The upper end of the first rotating rod 501 penetrates through the lower end of the U-shaped fixed seat 401 and is connected with the middle of the lower surface of the placing table 402. A hydraulic cylinder 403 is arranged on the upper surface of the U-shaped fixed seat 401. The lower end of the hydraulic cylinder 403 penetrates through the upper end of the U-shaped fixed seat 401 and is connected with a first servo motor 404. The power output end of the first servo motor 404 is drivingly connected with a limiting table 405;

[0035] The cleaning mechanism 2 6 includes a horizontal moving plate 601, and the horizontal moving plate 601 is slidably installed in front of the baffle 2. A lifting plate 602 is slidably installed inside the front end of the horizontal moving plate 601, so that the lifting plate 602 can move vertically on the horizontal moving plate 601. A servo motor 2 603 is arranged at the front end of the lifting plate 602 through a motor seat. The power output end of the servo motor 2 603 is connected to a rotating shaft 1 604 through a coupling transmission. The circumferential surface of the rotating shaft 1 604 is provided with a groove wheel 605. A row of pins 606 matching the groove wheel 605 are evenly arranged on the surface. The upper end of the lifting plate 602 is fixedly connected to an L-shaped scraper 608 through a connecting plate 607, and the lower end of the L-shaped scraper 608 abuts against the upper surface of the base 1. A rotating shaft 609 is rotatably installed inside the upper left end of the L-shaped scraper 608, and two rotating shafts 609 are arranged in front and behind. The lower ends of the two rotating shafts 609 are both provided with sweeping brushes 610. The sweeping brush 610 can sweep up the waste on the base 1 when moving to the left, and then The L-shaped scraper 608 can push the waste to the left more smoothly into the impurity drop port 14. The circumferential surfaces of the upper ends of the two rotating shafts 609 are respectively provided with a transmission spur gear 1 611 and a transmission spur gear 2 613, and the rear end of the transmission spur gear 1 611 is meshed with the front end of the transmission spur gear 2 613. The front end of the transmission spur gear 1 611 is meshed with a fixed tooth plate 612, and the fixed tooth plate 612 is arranged on the surface of the baffle 2. The arrangement enables the transmission spur gear 1 611 and the transmission spur gear 2 613 to rotate when the L-shaped scraper 608 moves horizontally to the left, thereby causing the sweeping brush 610 to rotate, and the waste on the base 1 to be smoothly stirred up. A through groove 11 is provided at the front end of the L-shaped scraper 608, and the fixed tooth plate 612 is arranged on the same horizontal line as the through groove 11. A movable groove 2 13 is provided on the left side of the L-shaped scraper 608, and the right ends of the transmission spur gear 1 611 and the transmission spur gear 2 613 are both arranged inside the movable groove 2 13.

[0036] It should be noted that the arrangement of the groove wheel 605 and the pin 606 enables the servo motor 2 603 to drive the groove wheel 605 to rotate when it is working, so that the groove wheel 605 contacts the bottom of the pin 606, so that the horizontal movable plate 601 is subjected to a leftward thrust and moves to the left, and then after the leftmost end, the groove wheel 605 contacts the leftmost pin 606 to generate an upward thrust, so that the lifting plate 602 moves upward, and then the groove wheel 605 contacts the upper surface of the pin 606, generating a rightward thrust, pushing the horizontal movable plate 601 to move to the right, and finally the groove wheel 605 contacts the right end of the pin 606 again, generating a downward force, thereby resetting and realizing a cyclic reciprocating movement.

[0037] The front surface of the baffle 2 is provided with a moving groove 8 and an annular groove 9. There are two moving grooves 8 symmetrically arranged up and down. The rear sides of the upper and lower ends of the horizontal moving plate 601 are respectively slidably installed inside the two moving grooves 8. The setting of the moving groove 8 can limit the installation of the horizontal moving plate 601 while not affecting the left - right horizontal movement of the horizontal moving plate 601. An active block 10 is slidably installed inside the annular groove 9. The rear end of the first rotating shaft 604 penetrates through the horizontal moving plate 601 and is rotatably installed inside the front end of the active block 10. The setting of the annular groove 9 can limit the moving paths of the active block 10 and the first rotating shaft 604, and then enable the first rotating shaft 604 and the active block 10 to reciprocate inside the annular groove 9;

[0038] A workpiece 7 is inserted into the upper end of the placing table 402. The rear end and the lower surface of the rear end of the cleaning brush 506 are respectively abutted against the upper surface and the side surface of the placing table 402, and the upper surface of the rear end of the cleaning brush 506 does not contact the lower surface of the front end of the workpiece 7. Because the placing table 402 is designed in a similar circular stepped shape, after the workpiece 7 is placed on the surface of the placing table 402, the lower end of the workpiece 7 does not contact the upper surface of the lowermost end of the placing table 402. At this time, during the rotary cutting process, some waste chips generated will fall on the surface of this part of the placing table 402 along with the coolant. The setting of the cleaning brush 506 can clean this surface, so as to sweep the waste chips and the coolant to the impurity falling port 14, avoiding the waste chips remaining on the placing table 402, which may cause the waste chips to be thrown everywhere when the placing table 402 rotates and pollute the working environment. A拨动板507 is abutted against the left front of the cleaning brush 506, and the拨动板507 is installed on the lower surface of the U - shaped fixed seat 401 through a mounting rod 508. The setting of the拨动板507 can, when the cleaning brush 506 rotates,拨动 the left front of the cleaning brush 506, so that the waste chips that may adhere to the cleaning brush 506 are pulled off. Among them, the left front end of the U - shaped fixed seat 401 is designed as a slope, so that the pulled - off waste chips can fall on this slope, and then fall to the impurity falling port 14 through the vibration of the device and natural falling.

[0039] Embodiment 2:

[0040] Please refer to Figure 1 - Figure 3 and Fig. 9 It should be noted that there is an unclear "拨动板" in the original Chinese text. It may need to be further clarified according to the actual situation to ensure the accuracy of the translation.As shown, an impurity filter plate 15 is arranged below the impurity drop port 14, and the left and right ends of the impurity filter plate 15 are movably mounted inside the base 1 through a spring return mechanism 16, wherein the spring return mechanism 16 is a prior art, so it is not described in detail. The impurity filter plate 15 is arranged to block the waste on the upper surface of the impurity filter plate 15, so that the coolant falls into the inner bottom of the base 1 through the filter hole for recycling. An impurity discharge port 17 is provided at the left end of the base 1, and a sealing plate 18 is hinged inside the impurity discharge port 17. The sealing plate 18 is arranged to close the impurity discharge port 17 when not in use. The left end of the impurity filter plate 15 is arranged on the impurity filter plate 15. The inside of the material discharge port 17, and a collection box 20 is arranged below the left end of the impurity filter plate 15, and the right end of the collection box 20 is plugged into the left outer wall of the base 1 through an insert block, so as to facilitate the quick disassembly and replacement of the collection box 20, and then during the continuous processing, when the collection box 20 is full of waste chips, the collection box 20 can be quickly replaced without affecting the work. The lower end of the rotating rod 501 passes through the upper end of the base 1 and is fixedly connected with a rotating disk 509, and five protrusions 510 are arranged on the circumferential surface of the rotating disk 509, and the rotating disk 509 and the protrusions 510 are both arranged on the right side of the impurity filter plate 15, and the protrusions 510 can contact the right end of the impurity filter plate 15;

[0041] It should be noted that, through the arrangement of the five protrusions 510 on the turntable 509, when the turntable 509 drives the protrusions 510 to rotate, when the protrusions 510 contact the right end of the impurity filter plate 15, the impurity filter plate 15 is pushed to the left, and when the protrusions 510 do not contact the impurity filter plate 15, the impurity filter plate 15 is reset to the right under the action of the spring reset mechanism 16, achieving left and right reciprocating movement, and then the impurities on the surface of the impurity filter plate 15 can be vibrated to shake the impurities to the left, and then fall into the interior of the collection box 20 through the impurity discharge port 17.

[0042] A sealing groove 21 and a storage groove 22 are provided on the left side wall of the base 1, and two groups of storage grooves 22 are symmetrically arranged front and back. The two groups of storage grooves 22 are connected to the sealing groove 21, and the size of the sealing groove 21 matches the sealing plate 18. The setting of the sealing groove 21 provides installation space for the front and rear ends of the sealing plate 18. Support rods 19 are rotatably installed inside the lower ends of the two groups of storage grooves 22. The upper ends of the two support rods 19 are respectively inserted into the right side inside the front and rear ends of the sealing plate 18. The setting of the storage grooves 22 provides storage space for the support rods 19, so that the support rods 19 can be stored inside the storage grooves 22 when not in use.

[0043] When the present invention is in use, the workpiece 7 is first inserted and placed on the placement table 402, and then the hydraulic cylinder 403 is started. The hydraulic cylinder 403 drives the servo motor 404 and the limiting table 405 to move downward. The limiting table 405 cooperates with the placement table 402 to limit and fix the workpiece 7. Then the rolling mechanism 3 works to roll the workpiece 7. At the same time, the servo motor 404 rotates, and the workpiece 7 and the placement table 402 are driven to rotate through the limiting table 405, so that the rolling mechanism 3 can cut the gear teeth on the entire circumferential surface of the workpiece 7. At the same time, during the working process, the coolant sprayed from the rolling mechanism 3 can wash away the waste chips downward, so that most of the waste chips and coolant directly pass through the inside of the impurity drop port 14 base 1, and a small part of the waste chips and coolant will fall on the surface of the placement table 402.

[0044] When the placement table 402 rotates, it can simultaneously drive the rotating rod 1 501 and the rotating spur gear 502 to rotate, and then drive the driven spur gear 2 504, the rotating rod 2 505 and the cleaning brush 506 to rotate through the driven spur gear 1 503. Here, the placement table 402 and the cleaning brush 506 both rotate counterclockwise. The rotation of the cleaning brush 506 will sweep away the waste chips and coolant on the placement table 402, and then drop them into the interior of the base 1 through the impurity drop port 14, so as to prevent the waste chips from being thrown to various parts of the machine and affecting subsequent cleaning under the rotation of the placement table 402.

[0045] During the processing, servo motor 2 603 is started at the same time, and servo motor 2 603 drives shaft 1 604 and groove wheel 605 to rotate. The groove wheel 605 rotates in cooperation with pin 606 and movable block 10, first driving horizontal moving plate 601 and the lifting plate 602 inside it to move horizontally to the left, and then move to the leftmost end of the annular groove 9. Due to the limitation of the horizontal moving plate 601, the groove wheel 605 continues to rotate at this time, so that the lifting plate 602 moves upward, and then the horizontal moving plate 601 and the lifting plate 602 move horizontally to the right. After moving to the rightmost end of the annular groove 9, the lifting plate 602 moves downward again, realizing a one-time movement and closure of the horizontal moving plate 601 and the lifting plate 602, and the water During the movement of the horizontal moving plate 601 and the lifting plate 602, the L-shaped scraper 608 connected by the connecting plate 607 will also perform the working steps of horizontally moving to the left, moving upward, moving horizontally to the right, and moving downward, so that when the L-shaped scraper 608 moves horizontally to the left, the waste chips that may fall on the front end surface of the base 1 are pushed to the left into the impurity drop opening 14, and then the L-shaped scraper 608 moves upward, so that the lower end of the L-shaped scraper 608 is no longer in contact with the upper surface of the base 1, so as to avoid pushing the waste chips and impurities generated during the movement to the right when the L-shaped scraper 608 moves to the right, and then moves downward again, so that the lower end of the L-shaped scraper 608 is in contact with the upper surface of the base 1, and can wait for the next material pushing work;

[0046] The rotating rod 501 also drives the rotating disk 509 and the protrusion 510 to rotate during the rotation, so that the impurity filter plate 15 can vibrate left and right under the cooperation of the protrusion 510 and the spring return mechanism 16, so that the impurities are smoothly shaken off to the left side, and then discharged through the impurity discharge port 17 into the interior of the collection box 20, so as to avoid the accumulation of impurities and clogging the filter holes.
