A groove 34 is formed at the top of the support platform 15, and a vertical groove 37 is formed at the bottom of one side of the groove 34. A pulley 42 is rotatably connected to the bottom of the horizontal plate 35. The pulley 42 is located on one side of the cleaning plate 36 and is slidably connected inside the groove 34. When the horizontal plate 35 moves together with the push block 32, it will drive the pulley 42 to move together. Since the pulley 42 is slidably located inside the groove 34, it facilitates the movement of the horizontal plate 35.

By setting the second baffle 44 at the top of the first hydraulic rod 5, the top of the first hydraulic rod 5 can be protected.

[0038] In this embodiment, in order to solve the problem that long cutting chips are difficult to break during gear machining, when the gear needs to be machined, the moving table 4 is pushed to one side of the support table 15 through the first hydraulic rod 5, when the position of the blank block 14 needs to be fixed, the blank block 14 is placed on the support table 15, and the second hydraulic rod 8 is started to push the rotator 9 and the three-jaw clamp 10 to one side until the one side of the blank block 14 extends into the inner control of the three-jaw clamp 10, the outer wall of one end of the blank block 14 can be fixed by the three-jaw clamp 10, then the third hydraulic rod 11 is started, the sharp rod can be pushed to the other side of the blank block 14 through the third hydraulic rod 11 until the two sides of the blank block 14 are fixed by the three-jaw clamp 10, by setting the fourth hydraulic rod 12, when the blank block 14 needs to be cut, the gear cutting machine 13 is pushed downward by the fourth hydraulic rod 12 to move downward to machine the blank block 14, when the blank block 14 needs to be rotated, the three-jaw clamp 10 is driven to rotate by the servo motor arranged inside the rotator 9, so that the blank block 14 clamped by the three-jaw clamp 10 is rotated together, and after the blank block 14 is rotated by a specified angle, the gear cutting machine 13 can machine the surface of the blank block 14 again, so that the outer wall of the blank block 14 forms a toothed protrusion;

[0039] When a long cutting chip is encountered, the motor 16 can be started and the half gear 17 is driven to rotate by the motor 16. Since the inner wall of the sliding frame 19 is provided with a plurality of groups of protrusions on both sides, when the half gear 17 rotates, it will drive the sliding frame 19 to move in one direction by engaging with one side first, and when the half gear 17 engages with the other side, it will drive the sliding frame 19 to move in the opposite direction, so that the sliding frame 19 is driven to move reciprocatingly in the inner wall of the supporting piece 18 by the rotation of the half gear 17. When the sliding frame 19 moves to one side of the blank block 14, it will drive the pull rod 20 and the plurality of hooks 21 on one side to move together. When the sliding frame 19 and the pull rod 20 move to one side of the blank block 14, the rack 24 at the bottom of the pull rod 20 will be driven to move, which will drive the transmission gear 25 engaged with the rack 24 to rotate. When the transmission gear 25 rotates, it will drive the bidirectional screw rod 23 to rotate, and the bidirectional screw rod 23 will drive the two groups of nuts 26 provided on the outer wall to move to both sides at the same time. When the nuts 26 move, they will drive the connecting rod 27 and the cutting knife 28 to move together. By providing the bottom frame 29 at the bottom of the side plate 22, when the connecting rod 27 moves, the connecting rod 27 will slide in the sliding groove of the bottom frame 29, which facilitates limiting the movement track of the connecting rod 27 and the cutting knife 28. When the two groups of cutting knives 28 move to both sides at the same time, the pull rod 20 can pass between the two groups of cutting knives 28. When the hooks 21 move to below the contact position between the gear shaping machine 13 and the blank block 14, the longer cutting chip will be hooked by the plurality of hooks 21. Then the sliding frame 19 will reset to the other side, which will drive the pull rod 20 and the hooks 21 to move together to pull the longer cutting chip, so as to facilitate pulling the cutting chip away from the blank block 14. When the hooks 21 on the pull rod 20 hook the longer cutting chip and reset to one side, the rack 24 will move in the opposite direction, and the movement of the rack 24 will drive the transmission gear 25 and the bidirectional screw rod 23 to rotate in the opposite direction. When the bidirectional screw rod 23 rotates in the opposite direction, it will drive the two groups of nuts 26, the connecting rod 27 and the cutting knife 28 to move to the center at the same time. After the pull rod 20 moves away from between the two groups of cutting knives 28, the two groups of cutting knives 28 will move to the center at the same time to cut the longer cutting chip;

[0040] After the blank block 14 is processed, the fifth hydraulic rod 31 can be started to push the push block 32 to move to one side, so that the push block 32 is pushed to the bottom of the processed blank block 14, and because the surface of the processed blank block 14 has a plurality of groups of convex teeth, a plurality of groups of tooth-shaped grooves arranged on the curved surface of the push block 32 can be clamped on the surface of the processed blank block 14, so that the position of the processed blank block 14 can be fixed, then the second hydraulic rod 8 and the third hydraulic rod 11 are retracted, so that the three-jaw clamp 10 and the sharp rod are moved away from both sides of the blank block 14, so that the processed blank block 14 is lifted by the push block 32, and the fifth hydraulic rod 31 is continuously started to push the push block 32 and the processed blank block 14 to one side until the processed blank block 14 is pushed into the falling basket 33, so that the operator can take it out, and by arranging the protective pad 41 made of rubber in the inside of the falling basket 33, the surface of the processed blank block 14 can be protected by the protective pad 41 when the processed blank block 14 falls into the falling basket 33, so as to prevent it from being scratched;
