[0087] Further, with specific reference to Figure 3 、 Figure 5 、 Figure 6 as shown:

[0088] The feeding unit 200 comprises a feeding rack 201 and a material guide groove 202, the feeding rack 201 is fixedly installed at the top of the machining rack 100 and distributed front and back, the spacing between the two feeding racks 201 is adapted to the size specifications of the rolling mill guide roller, and the material guide groove 202 is opened at the top of the two feeding racks 201;

[0089] The conveying unit 300 comprises an aluminum profile frame 301, a first bearing seat 302, a rotating shaft 303, a rotating tray 304, a U-shaped positioning notch 305, a first servo motor 306, a driving synchronous wheel 307, a driven synchronous wheel 308, a synchronous belt 309 and an assembly plate 3010. The aluminum profile frame 301 is fixedly installed on the top of the machining rack 100 in front and back distribution. The first bearing seat 302 is fixedly installed on the side face close to the two aluminum profile frames 301 and extends to the right end of the first bearing seat 302. The rotating shaft 303 is rotatably installed in the first bearing seat 302. The rotating tray 304 is fixedly installed on the outer wall of the rotating shaft 303 in front and back distribution. The distance between the two rotating trays 304 is matched with the size of the rolling mill guide roller. The two rotating trays 304 are located outside the feeding frame 201. The U-shaped positioning notch 305 is evenly arranged on the outer wall of the rotating tray 304. The size of the U-shaped positioning notch 305 is matched with the size of the rolling mill guide roller. The first servo motor 306 is fixedly installed in the machining rack 100. The driving synchronous wheel 307 is fixedly installed on the output shaft of the first servo motor 306. The driven synchronous wheel 308 is fixedly installed on the outer wall of the rotating shaft 303. The synchronous belt 309 is sleeved on the driving synchronous wheel 307 and the driven synchronous wheel 308.

[0091] Specifically, the mill guide rollers are placed in the material guide groove 202 in sequence, so that the outer wall of the center shaft of the mill guide roller abuts against the inner wall of the material guide groove 202. It should be noted that the right end of the material guide groove 202 is lower than the left end, so the mill guide rollers inside the material guide groove 202 always have the potential to roll to the right. Then, the output shaft of the first servo motor 306 drives the driving synchronous wheel 307 to rotate clockwise, which further drives the driven synchronous wheel 308 to rotate clockwise through the synchronous belt 309. The rotation of the driven synchronous wheel 308 drives the rotating shaft 303 and the two rotating material discs 304 to rotate. When one of the two U-shaped positioning slots 305 of the front and rear rotating material discs 304 rotates to the position of the two material guide grooves 202, the center shaft of the rightmost mill guide roller inside the material guide groove 202 rolls into the U-shaped positioning slots 305, and then rotates upward to the top position with the rotating material disc 304. Then, the inner holes at both ends of the center shaft are machined by the cutting unit 400. After the machining is completed, the output shaft of the first servo motor 306 continues to drive the driving synchronous wheel 307 to rotate clockwise, which drives the driven synchronous wheel 308 and the rotating shaft 303 to rotate clockwise through the synchronous belt 309. The rotation of the rotating shaft 303 drives the front and rear rotating shafts 303 to rotate, and the machined mill guide rollers are conveyed to the right to the top of the two material guide blocks 700, and then slide along the top of the material guide blocks 700 to the right end of the device, completing the automatic feeding of the machined mill guide rollers. The whole process is highly automated and does not require manual operation, with high processing efficiency.

The positioning plug blocks 6011 are symmetrically and fixedly installed at the bottom of the subsidence block 609. The positioning plug grooves 6012 are formed on the outer wall of the running tray 304 and are located at both sides of the opening of each U-shaped positioning slot 305. The specifications of the positioning plug grooves 6012 are matched with the specifications of the positioning plug blocks 6011. The third spring 6013 is fixedly installed between the top of the positioning pressing plate 603 and the bottom of the guide shaft support 601.

[0100] Specifically, the output shaft of the third servo motor 4014 drives the driving bevel gear 4015 to rotate, further drives the driven bevel gear 4013 engaged with the driving bevel gear 4015 to rotate, the driven bevel gear 4013 drives the positive and negative lead screw 4012 to rotate along the inside of the front and rear two No. 2 bearing seats 4011, pushes the two inner spiral pipes 4010 to the middle, the two inner spiral pipes 4010 further drive the two translation plates 404 to move to the middle, the translation plates 404 drive the foot support plate 405, the connecting plate 406 and the push-pull rod 606 to move together, thereby generating a downward wedge force on the folding block 605, further pushing the push-pull block 604 downward, the push-pull block 604 moves downward to drive the positioning pressing plate 603 to move downward through the two guide vertical shafts 602, the positioning pressing plate 603 moves downward to further drive the front and rear two extension rods 608 to move downward together, through the connection of the No. 2 spring 6010, drives the extension rod 608, the settlement block 609 and the left and right two positioning insert blocks 6011 to move downward together, makes the two positioning insert blocks 6011 inserted into the two positioning insert grooves 6012 located at both ends of the U-shaped positioning slot 305, realizes the angle positioning of the running tray 304, prevents the running tray 304 from rotating, thereby ensuring the cutting precision.

[0101] The rolling mill guide roller thread cutting equipment of the scheme is used for placing the rolling mill guide rollers in the material guide groove 202 in sequence, so that the outer wall of the center shaft of the rolling mill guide roller abuts against the inner wall of the material guide groove 202. It should be noted that the right end of the material guide groove 202 is lower than the left end, so the rolling mill guide roller in the material guide groove 202 always has the potential energy of rolling to the right. Then, the output shaft of the first servo motor 306 drives the driving synchronous wheel 307 to rotate clockwise, and further drives the driven synchronous wheel 308 to rotate clockwise through the synchronous belt 309. The rotation of the driven synchronous wheel 308 drives the rotating shaft 303 and the two rotating material discs 304 to rotate together. When one of the two U-shaped positioning slots 305 of the front and rear rotating material discs 304 rotates to the position of the two material guide grooves 202, the center shaft of the rolling mill guide roller at the right end in the material guide groove 202 rolls into the two U-shaped positioning slots 305, and rotates upward with the rotating material disc 304, until it is rotated to the position between the front and rear cutting tool heads 409, and the first servo motor 306 stops rotating. During the rotation of the front and rear rotating material discs 304, the top pin 502, the first spring 503, the ball sleeve 504 and the ball stem 505 are also rotated through the sliding hole 501, so that the ball stem 505 rotates along the inner wall of the fixed ring 507. When the ball stem 505 rotates to the position of the inclined guide surface 509, the ball stem 505 is finally rolled to the inner side of the arc-shaped guide rail 508 through the guidance of the inclined guide surface 509, so as to press the top pin 502 towards the rolling mill guide roller, and the first spring 503 is compressed. Since the front and rear top pins 502 are pressed and moved towards the middle, the rolling mill guide roller in the U-shaped positioning slot 305 is positioned in the middle, so as to ensure that the rolling mill guide roller is located in the middle position between the front and rear rotating material discs 304, and further ensure that the thread cutting lengths of the inner holes at both ends of the center shaft of the rolling mill guide roller are consistent. At the same time, the front and rear top pins 502 press the rolling mill guide roller from front to back, so that the rolling mill guide roller can be positioned in the U-shaped positioning slot 305, so that the rolling mill guide roller can be avoided from loosening during thread cutting, so as to ensure the stability of processing and improve the processing precision.

[0102] Then, the output shaft of the third servo motor 4014 drives the driving bevel gear 4015 to rotate, further drives the driven bevel gear 4013 engaged with the driving bevel gear 4015 to rotate, the driven bevel gear 4013 drives the positive and negative screw rod 4012 to rotate along the inside of the front and rear two No. 2 bearing seats 4011, pushes the two inner spiral pipes 4010 to the middle, the two inner spiral pipes 4010 further drive the two translation plates 404 to move to the middle, the translation plates 404 drive the foot support plate 405, the connecting plate 406 and the push rod 606 to move together, thereby generating a downward wedge force on the folding block 605, further pushing the push block 604 downward, the push block 604 moves downward through the two guide vertical shafts 602 to drive the positioning plate 603 to move downward, the positioning plate 603 moves downward to further drive the front and rear two extension rods 608 to move downward together, through the connection effect of the No. 2 spring 6010, the extension rod 608, the settlement block 609 and the left and right two positioning blocks 6011 are driven to move downward together, so that the two positioning blocks 6011 are inserted into the two positioning slots 6012 at both ends of the U-shaped positioning slot 305, the angle positioning of the running tray 304 is realized, the rotation of the running tray 304 is prevented, and the precision of subsequent cutting is ensured, then, the two running trays 304 continue to move to the middle, through the connection effect of the foot support plate 405 and the motor mounting plate 407, the No. 2 servo motor 408 and the cutting tool head 409 are driven to move together, at the same time, the two No. 2 servo motors 408 drive the two cutting tool heads 409 to rotate, and threads are cut in the inner holes at the two ends of the center line of the rolling mill guide roller;

[0103] Subsequently, the output shaft of the third servo motor 4014 rotates reversely, causing the two translation plates 404 to move away from each other, further causing the two push rods 606 and the second servo motor 408 to move together, withdrawing the cutting tool head 409 from the inside of the threaded holes at both ends of the center shaft of the rolling mill guide roller, and the two push rods 606 moving away from each other gradually releases the wedge force on the two bending blocks 605, causing the third spring 6013 to release the tension, pulling the positioning plate 603 to move upwards, and driving the two guide vertical shafts 602, the push blocks 604, the bending blocks 605, the sheet metal bracket 607, the telescopic rod 608, the sinking block 609 and the positioning plug 6011 to move, causing the positioning plug 6011 to exit from the inside of the positioning slot 6012, releasing the angle positioning of the rotating tray 304. Then, the output shaft of the first servo motor 306 continues to drive the driving synchronous wheel 307 to rotate clockwise, and under the connection of the synchronous belt 309, drives the driven synchronous wheel 308 to rotate clockwise together with the rotating shaft 303, and the rotating shaft 303 rotates to drive the two rotating shafts 303 to rotate together, conveying the rolling mill guide roller with the cutting completed to the right to the top of the two discharging guide blocks 700. When the rolling mill guide roller approaches the top of the two discharging guide blocks 700, the two top pins 502 clamping the rolling mill guide roller rotate to the bottom end of the arc-shaped guide rail 508 together with the rotating tray 304, so that the elastic force of the first spring 503 around the top pin 502 is released, pushing the top pin 502 to slide along the inside of the slide hole 501 away from the rolling mill guide roller, releasing the front and rear clamping of the rolling mill guide roller, and finally causing the rolling mill guide roller to roll from the inside of the two U-shaped positioning slots 305 to the top of the two discharging guide blocks 700, and continue to slide to the right end of the device along the top of the discharging guide blocks 700, completing the automatic discharging of the rolling mill guide roller thread cutting.
