[0040] See also Figure 1 - Figure 8 As shown, a steel pipe cutting machine tool equipment for rotating shaft production includes a base 1, a material discharge table 2 is provided on the left side of the upper surface of the base 1, a mounting seat 3 is provided on the right side of the upper surface of the base 1, and two groups of mounting seats 3 are provided, and a driving mechanism 4, a pushing mechanism 5 and a limit clamping mechanism 6 are provided inside the mounting seat 3. The driving mechanism 4 includes a pressure rod 401, and there are two pressure rods 401 symmetrically provided front and back. The two pressure rods 401 are slidably installed inside the mounting seat 3 through a hollow mounting block 405. The left ends of the two pressure rods 401 are fixedly connected by a push rod 12, so that the staff can drive the two pressure rods 401 to move horizontally to the right together by pushing the push rod 12, wherein a protrusion is provided on both sides of the upper surface of the pressure rod 401, and the protrusion is convenient for connecting with the components in the upper pushing mechanism 5, so that the pressure rod 401 can move smoothly when it moves horizontally left and right. To drive the parts of the pushing mechanism 5 to move, the right end of the pressure rod 401 is provided with a return spring 402, and the right end of the return spring 402 is provided with a fixed block 403, and the fixed block 403 is arranged inside the right mounting seat 3. The setting of the return spring 402 can ensure that the position of the protrusion on the upper part of the pressure rod 401 will be located on the left side of the corresponding limit clamping mechanism 6 when the pressure rod 401 is not affected by external force or is fixed by clamping. The limit clamping mechanism 6 includes a transverse plate 601, and the transverse plates 601 are provided with four. The four transverse plates 601 are respectively provided on the inner sides of the two pressure rods 401, and the inner ends of the four transverse plates 601 are all provided with limited movable plates 602. The inner ends of the limited movable plates 602 are fixedly connected to the clamping block 604 through the connecting column 603. The inner side of the clamping block 604 is provided with a V-shaped clamping groove. A cutting mechanism 7 and an automatic unlocking mechanism 8 are provided between the two sets of mounting seats 3;

[0041] It should be noted that the setting of the V-groove on the inner side of the clamping block 604 will cause the clamping block 604 to clamp the fixed rotating shaft, and the rotating shaft will automatically slide toward the bottom center line of the V-groove each time it is clamped, which simplifies the operation and improves the repeat positioning accuracy. Compared with the existing flat plate clamping method, it increases the contact area and the static friction between each other, significantly reduces the sliding or rolling tendency in the rotating shaft groove, and the clamping is more firm and reliable. The rotating shaft is not prone to accidental displacement, vibration or rotation during the cutting process, thereby ensuring processing accuracy and operational safety.

[0042] Preferably, the inner walls of the upper and lower sides of the mounting seat 3 are provided with a slide groove 19 and a slide groove 2 11, and a return spring 2 605 is provided inside the slide groove 19. One end of the return spring 2 605 is fixedly connected to the side wall of the limit movable plate 602. The setting of the slide groove 19 provides installation and activity space for the upper and lower ends of the limit movable plate 602 and the return spring 2 605, so that the limit movable plate 602 can stably move horizontally forward and backward to avoid offset affecting the moving effect. The setting of the return spring 2 605 can When the clamping block 604 or the horizontal plate 601 is not affected by external force, the limit movable plate 602 is pushed to abut against the side of the slide groove 9 close to the pressure rod 401, thereby making the clamping block 604 move away from the rotating shaft, losing the clamping effect on the rotating shaft, and facilitating the loading and unloading of the rotating shaft. The upper and lower ends of the clamping block 604 are respectively slidably installed inside the slide groove 2 11. The setting of the slide groove 2 11 limits the clamping block 604, so that the clamping block 604 can move stably back and forth horizontally, avoiding the displacement of the clamping block 604 and affecting the clamping effect.

[0043] The cutting mechanism 7 includes a mounting frame 701, and the mounting frame 701 is arranged at the front end of the upper surface of the base 1 and is located between the two mounting seats 3. An electric cylinder 702 is arranged inside the side wall of the mounting frame 701, and the electric cylinder 702 is arranged obliquely downward. A cutting saw 703 is arranged at the telescopic end of the electric cylinder 702. Protective plates 704 are provided at the front and rear ends of the right side of the mounting seat 3. The inner sides of the two protective plates 704 are provided with movable grooves 705. Connecting blocks are slidably installed inside the two movable grooves 705, and the connecting blocks are respectively fixedly connected to the front and rear sides of the cutting saw 703. The setting of the movable groove 705 and the connecting block can limit the cutting saw 703 and also limit the travel direction of the cutting tool 703, so that when the electric cylinder 702 is working, it can drive the cutting saw 703 to move in the direction of the movable groove 705, and then drive the cutting saw 703 to move obliquely downward or obliquely upward;

[0044] It should be noted that clamping blocks 604 are provided on both sides of the cutting mechanism 7, so that when the four clamping blocks 604 clamp the rotating shaft, they can clamp and fix both sides of the cutting point. The clamping effect on the left side prevents the rotating shaft from shaking or rotating to affect the cutting. The clamping effect on the right side prevents the cutting saw from breaking or notching when the right part is cut during the cutting process, thereby improving the cutting quality.

[0045] The automatic unlocking mechanism 8 includes a lower pressure plate 801 and a lever 802. The upper end of the lower pressure plate 801 is fixedly connected to the lower surface of the rear side of the cutting saw 703. Two levers 802 are symmetrically provided in front and back, and the middle parts are rotatably mounted on the upper surface of the base 1 through a fulcrum 804. The lower surfaces of the two levers 802 close to the unloading platform 2 are provided with lifting springs 803, and the lower ends of the lifting springs 803 are connected to the upper surface of the base 1. The lower surfaces of the two levers 802 away from the unloading platform 2 are provided with blocking blocks 805.

[0046] A slot 404 is provided on the inner side of the pressure rod 401, and the slot 404 matches the block 805. The arrangement of the slot 404 allows the block 805 to be stuck in the slot 404 after the pressure rod 401 moves horizontally to the right, thereby fixing the pressure rod 401 and preventing the return spring 402 from pushing the pressure rod 401 back to its original position. A movable slot 10 is provided on the side wall of the mounting frame 701. The front end of the front lever 802 passes through the movable slot 10 and extends above the front pressure rod 401. The arrangement of the movable slot 10 provides space for the front lever 802 to move, allowing the lever 802 to rotate smoothly.

[0047] When the cutting saw 703 is cut off, the electric cylinder 702 will continue to drive the cutting saw 703 to move downward a short distance. At this time, the lower pressure plate 801 under the cutting saw 703 will contact the upper surface of the two levers 802 provided with one end of the lifting spring 803, and press this end downward, so that the other end of the lever 802 moves upward, driving the card block 805 to move out of the card slot 404, so that the pressure rod 401 loses its limiting and fixing effect, and then the elastic force of the reset spring 1 402 and the reset spring 2 605 is released, pushing the pressure rod 401 and the clamping block 604 to reset, so that the rotating shaft loses its clamping and fixing effect, which is convenient for the transfer and unloading of the rotating shaft, and then convenient for the continuous cutting of the rotating shaft.

[0048] When the present invention is in use, the rotating shaft to be cut is first placed on the unloading table 2, and then the rotating shaft is moved to the right to the length required for cutting, and the pressing rod 401 is pushed to the right by the push rod 12. When the pressing rod 401 is pushed to the right, the four sets of horizontal plates 601 are driven to move toward the rotating shaft through the pushing mechanism 5. The horizontal plate 601 drives the clamping block 604 to move toward the rotating shaft through the limiting movable plate 602 and the connecting column 603, so that the four clamping blocks 604 clamp the left and right sides of the rotating shaft cutting point. At the same time, the card slot 404 on the pressing rod 401 moves to the bottom of the card block 805, and the lifting spring 803 pushes one end of the lever 802 to move upward, so that the lever 802 drives one end of its card block 805 to press down, so that the card block 805 is inserted into the inside of the card slot 404, and the pressing rod 401 is limited and fixed;

[0049] Then the electric cylinder 702 is started, and the electric cylinder 702 drives the cutting saw 703 to move in the direction of the rotating shaft, so that the cutting saw 703 cuts the rotating shaft. After the cutting saw 703 cuts the rotating shaft, the electric cylinder 702 will drive the cutting saw to continue to move diagonally downward for a short distance, so that the lower pressure plate 801 presses down on one end of the lever 802, and then the lever 802 drives its other end to move upward, moving the block 805 out of the slot 404, losing the fixing effect on the pressure rod 401, and then the elastic force of the return spring 1 402 and the return spring 2 605 is released, and the return spring 1 402 pushes the pressure rod 401 to move to the left and return to its initial position. The return spring 2 605 pushes the limit moving plate 602 away from the rotating shaft, so that the clamping block 604 loses its clamping effect on the rotating shaft, which is convenient for the quick replacement of the rotating shaft and the next cutting work.

[0050] In a first embodiment of the present invention:

[0051] The pushing mechanism 5 includes a wedge block 1 501 and a wedge block 2 502, and there are four wedge blocks 1 501 and four wedge blocks 2 502. The four wedge blocks 1 501 are respectively arranged at the upper ends of the left and right sides of the two pressure rods 401. The right sides of the four wedge blocks 1 501 are respectively in contact with the four wedge blocks 2 502. The four wedge blocks 2 502 are respectively fixedly connected to the outer ends of the four cross plates 601. When the pressure rod 401 moves horizontally to the right, the pressure rod 401 will drive the wedge block 1 501 to move horizontally to the right, and the wedge block 1 501 will push the wedge block 2 502 to move in the direction of the rotation axis, so that the wedge block 2 502 can smoothly move the cross plate 601 in the direction of the rotation axis.

[0052] It should be noted that the wedge block has a small number of parts, an intuitive structure, no rotating joints or precision meshing parts, and is relatively easy to manufacture, assemble and maintain. The wedge block has a large contact surface and is in surface contact (or approximate line contact), which can withstand large pressure and impact loads and is not easily damaged.

[0053] In a second embodiment of the present invention:

[0054] The pushing mechanism 5 includes a spur gear 504, a tooth plate 1 505 and a tooth plate 2 506, and the rotating rod 1 503, the spur gear 504, the tooth plate 1 505 and the tooth plate 2 506 are all provided with four, the four tooth plates 1 505 are respectively provided on the left and right sides of the upper ends of the two pressure rods 401, the four tooth plates 2 506 are respectively fixedly connected to the outer ends of the four horizontal plates 601, and the four spur gears 504 are rotatably connected to the inner top wall of the mounting seat 3 through the rotating rod 1 503. The lower part of the side of the spur gear 504 away from the horizontal plate 601 is meshed with the tooth plate 1 505. The upper front end of 504 is meshed with tooth plate 2 506. Tooth plate 1 505 and tooth plate 2 506 are arranged one above the other, so that when tooth plate 1 505 moves horizontally left and right, it will not collide with tooth plate 2 506, thereby avoiding affecting the front and rear horizontal movement of tooth plate 2 506. When the pressure rod 401 moves horizontally to the right, it can drive tooth plate 1 505 to move horizontally to the right, thereby driving the spur gear 504 to rotate. Then, the spur gear 504 rotates and drives tooth plate 2 506 to move toward the rotation axis. Tooth plate 2 506 can push the cross plate 601 to move toward the rotation axis.

[0055] It should be noted that the setting of the gear and the tooth plate can flexibly adjust the transmission ratio (displacement amplification ratio) and output characteristics by changing the module of the gear, the number of teeth and the relative position of the rack and the gear, and then adjust the moving distance of the clamping block 604, so as to clamp and limit more rotating shafts of different diameters, thereby improving the scope of application.

[0056] In a third embodiment of the present invention:

[0057] The pushing mechanism 5 includes a toggle plate 507, a push plate 509 and a baffle 510, and there are four toggle plates 507, push plates 509 and baffles 510. A rotating rod 2 508 is provided in the middle of the four toggle plates 507, and the upper end of the rotating rod 2 508 is rotatably connected to the inner top wall of the mounting seat 3. The four toggle plates 507 are respectively arranged on one side of the outer end of the four horizontal plates 601, and the four push plates 509 are respectively arranged on the left and right sides of the upper ends of the two pressure rods 401. The upper ends of the four baffles 510 are fixedly connected to the inner top wall of the mounting seat 3 through the fixing rod 511. The outer end and the baffle 510 are in the same horizontal plane. When the pressure rod 401 is pushed to the right, the pressure rod 401 will drive the push plate 509 to move to the right, so that the push plate 509 pushes the outer end of the toggle plate 507 to rotate to the right. When the toggle plate 507 rotates, its inner end will rotate to the left. Then, during the rotation process, the inner end of the toggle plate 507 will abut against the cross plate 601, pushing the cross plate 601 in the direction of the rotation axis. After the toggle plate 507 is in a front-to-back horizontal state, the pushing work is completed. The setting of the baffle 510 is to limit the rotation space of the toggle plate 507 to prevent the toggle plate 507 from rotating too much and affecting the use effect.

[0058] It should be noted that the connecting rod mechanism can usually provide better rigidity and stability, so as to obtain a larger outward movement stroke of the cross plate 601 with a smaller displacement of the pressure rod 401, or obtain a larger lateral thrust with a smaller downward force, which is more labor-saving and convenient for the staff to push the pressure rod 401 to the right.
