Description

Technical Field

[0001] This invention relates to the field of CNC lathe technology, and in particular to a rotary automated CNC lathe and its usage method. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting internal and external cylindrical surfaces, internal and external conical surfaces with arbitrary cone angles, complex rotating internal and external curved surfaces, and cylindrical and conical threads on shaft-type or disc-type parts. They can also perform grooving, drilling, reaming, boring, and other machining operations. CNC machine tools automatically process parts according to pre-programmed machining procedures. The machining process route, process parameters, tool movement trajectory, displacement, cutting parameters, and auxiliary functions are compiled into a machining program sheet according to the instruction codes and program format specified by the CNC machine tool. The contents of this program sheet are then recorded on a control medium and input into the CNC device of the CNC machine tool, thereby directing the machine tool to process the parts.

[0003] In the prior art, patent application number CN201910882946.8 discloses a CNC double-head vertical lathe. This CNC double-head vertical lathe clamps the lower side of a ring-shaped workpiece with a clamping block, supports and positions the lower side of the ring-shaped workpiece with a rotating plate, and then uses two turning tools on the upper side to turn the inner and outer walls of the ring-shaped workpiece, achieving the effect of turning the inner and outer walls of the end of the ring-shaped workpiece. However, in practical applications, it is often necessary to turn the other end of the ring-shaped workpiece. Before turning the other end of the ring-shaped workpiece, it is necessary to first release the clamping of the ring-shaped workpiece, flip the ring-shaped workpiece, and then clamp and position the ring-shaped workpiece again. Finally, the other end is cut. When disassembling and flipping the ring-shaped workpiece, it is also necessary to clean the waste attached to the outer side of the ring-shaped workpiece to avoid the waste waste affecting the subsequent cutting work. However, this operation method is relatively cumbersome and affects the processing efficiency of the ring-shaped workpiece. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a rotary automated CNC lathe and its usage method.

[0017] Preferably, telescopic tubes are provided between the mounting bracket and the connecting bracket, as well as between the connecting plate and the first sleeve.

[0018] Preferably, a take-up rod is fixed to the bottom of the reciprocating screw, a first drum is provided on the take-up rod, a first pull rope is wound and connected to the first drum, and the end of the first pull rope away from the first drum is connected to a connecting plate. A second drum is also provided on the take-up rod, a second pull rope is wound and connected to the second drum, and the end of the second pull rope away from the second drum passes through the mounting frame and the upper rotating plate and is connected to a slider. A groove for sliding the slider is provided on the upper rotating plate, and a second elastic element is provided between the inner wall of the groove and the slider.

[0019] Preferably, the processing unit includes a first hydraulic cylinder fixed on the frame, the piston rod of the first hydraulic cylinder being connected to a movable seat that is slidably connected to the frame, a second hydraulic cylinder being fixed on the movable seat, and the piston rod of the second hydraulic cylinder being connected to a processing tool holder.

[0020] This invention also discloses a method for using a rotary automated CNC lathe, comprising the following steps:

[0021] S1: Place the ring-shaped workpiece to be processed on the rotating seat. The upper rotating plate is pressed by the elastic telescopic rod and moves relative to the lower rotating plate. The elastic telescopic rod deforms and thus buffers and unloads the force when the ring-shaped workpiece is lowered.

[0022] S2: Then the staff controls the clamping mechanism to work. The output shaft of the second motor drives the screw to rotate. The first sleeve moves along the screw axis. The first sleeve drives the clamping plate to move through the connecting plate and the sleeve, so that the clamping plate clamps the ring workpiece placed on the rotating seat.

[0023] When the first sleeve moves, it drives the elastic telescopic rod on the connecting plate to move, so that the elastic telescopic rod is inserted into the insertion hole of the upper rotating plate, thus fixing the height position of the upper rotating plate at this time.

[0024] S3: Then the operator controls the machining unit to work, so that the first hydraulic cylinder and the second hydraulic cylinder work together until the machining tool holder is placed on the upper side of the ring workpiece and abuts against the upper side wall of the ring workpiece. At this time, the first motor is controlled to run, and the first motor drives the ring workpiece held on the rotating seat to rotate, thereby realizing the cutting work of the ring workpiece.

[0025] S4: After the cutting of the upper end of the ring workpiece is completed, the operator controls the third motor to run. The output shaft of the third motor drives the sleeve to rotate through the drive rod, so that the sleeve rotates the ring workpiece in the clamping plate.

[0026] S5: When the output shaft of the third motor rotates, the outer incomplete bevel gear meshes with the secondary bevel gear at the end of the lifting rod, and the lifting rod drives the reciprocating screw to rotate. When the reciprocating screw rotates, the second sleeve first moves upward along its axis. After the second sleeve moves to the upper end of the reciprocating screw, it automatically moves downward along its track groove, so that the second sleeve drives the ring workpiece in the clamp to shake up and down through the connecting frame, shaking off the debris generated during the processing of the outer side of the ring workpiece.

[0027] When the reciprocating screw rotates, it drives the winding rod to rotate. The first drum on the winding rod winds up the first pull rope, and the second drum winds up the second pull rope. When the second pull rope is wound up, it first drives the slider to move down in the groove, and the second elastic element is compressed. When the first pull rope is wound up, it drives the elastic telescopic rod to move out of the insertion hole through the connecting plate. After the elastic telescopic rod moves out of the insertion hole, the first pull rope pulls down the upper rotating plate through the slider, and the elastic telescopic rod is further compressed, so that the upper rotating plate moves down and does not obstruct the flipping ring workpiece.

[0028] S6: After the third motor drives the upper and lower ends of the ring workpiece to change positions via the clamping plate, the incomplete bevel gear no longer meshes with the secondary bevel gear, the winding rod no longer pulls the connecting plate and the upper rotating plate, and the elastic telescopic rod pushes the upper rotating plate to move upward, so that the top surface of the upper rotating plate abuts against the bottom surface of the ring workpiece, and the elastic telescopic rod is re-inserted into the insertion hole, fixing the height of the upper rotating plate at this time, so that the upper rotating plate supports and limits the bottom of the ring workpiece. Then the machining department performs cutting work on the upper end of the ring workpiece.

[0029] Compared with the prior art, the present invention provides a rotary automated CNC lathe and its method of use, which has the following beneficial effects:

[0030] 1. This rotary automated CNC lathe and its usage method, through the cooperation of the clamping mechanism and the rotating mechanism, can quickly flip the ring workpiece and then perform cutting processing on both ends of the ring workpiece while stably supporting and clamping it, thereby improving the processing efficiency of the ring workpiece. During the flipping of the ring workpiece, the shaking component works automatically to automatically clean the debris on the surface of the ring workpiece, reducing the workload of the workers and ensuring the processing quality of the ring workpiece.

[0031] 2. The rotary automated CNC lathe and its usage method, by driving the ring workpiece to flip through the rotary mechanism, make the upper rotating plate no longer restricted by the elastic telescopic rod, and automatically move down under the tension of the second pull rope, so as to avoid the upper rotating plate obstructing the flipped ring workpiece, thereby making the ring workpiece processing stable.

[0032] 3. This rotary automated CNC lathe and its operating method, when the incomplete bevel gear is not meshing with the secondary bevel gear, the winding rod will no longer pull the connecting plate and the upper rotating plate. The elastic telescopic rod pushes the upper rotating plate upward. During the upward movement of the upper rotating plate, the squeezing inclined surface at the end of the elastic telescopic rod pushes the elastic telescopic rod to avoid the upward movement of the upper rotating plate until the top surface of the upper rotating plate abuts against the bottom surface of the annular workpiece. Then, under the pull of the first elastic element, the elastic telescopic rod is re-inserted into the insertion hole, and the height of the upper rotating plate is fixed again. This allows the upper rotating plate to support and limit the bottom of the annular workpiece, effectively preventing the annular workpiece from shifting downward under force during cutting and ensuring the machining quality of the annular workpiece.

[0033] 4. The rotary automated CNC lathe and its usage method, by setting multiple elastic telescopic rods at unequal intervals on the connecting plate, ensures that at least one elastic telescopic rod is always aligned with the insertion hole and plugged in, while the remaining elastic telescopic rods that are not aligned with the insertion hole automatically retract, thereby ensuring the stable support state of the upper rotating plate for the ring-shaped workpiece.

Detailed Implementation

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0047] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0048] Example 1: Refer to Figure 1 , Figure 2 , Figure 4 and Figure 7 A rotary automated CNC lathe includes a frame 1, and further includes:

[0049] Rotary seat 2 is rotatably mounted on frame 1, and a first motor 101 for driving the rotation of the rotary seat 2 is provided at the bottom of frame 1;

[0050] The clamping mechanism is fixed on the side of the rotating seat 2 and is used to clamp the annular workpiece placed on the rotating seat 2. The clamping mechanism includes a clamping plate 3 and a clamping assembly for driving the clamping plate 3 to move.

[0051] A rotating mechanism, mounted on the clamping mechanism, is used to drive the clamping plate 3 to rotate; and

[0052] A shaking component is mounted on the clamping mechanism and is used to drive the rotating mechanism to reciprocate and shake.

[0053] The top of the frame 1 is provided with a machining section for machining the annular workpiece on the rotary seat 2.

[0054] Furthermore, the rotating base 2 includes a lower rotating plate 201 rotatably connected to the frame 1, an elastic telescopic rod 202 disposed on the lower rotating plate 201, and an upper rotating plate 203 disposed on the top of the elastic telescopic rod 202. The output shaft of the first motor 101 passes through the frame 1 and is connected to the lower rotating plate 201.

[0055] Specifically, the annular workpiece to be processed is placed on the rotating seat 2. The upper rotating plate 203 is pressed by the elastic telescopic rod 202 and moves relative to the lower rotating plate 201. The elastic telescopic rod 202 deforms, thus buffering and unloading the downward movement of the annular workpiece. Then, the operator controls the clamping mechanism to drive the clamping plate 3 to clamp and position the annular workpiece placed on the rotating seat 2. Then, the upper end of the annular workpiece is cut by the processing unit. After the upper end of the annular workpiece is cut, the clamping mechanism works in conjunction with the rotating mechanism to quickly flip the annular workpiece while stably supporting and clamping it, and then cut both ends of the annular workpiece, improving the processing efficiency of the annular workpiece. During the flipping of the annular workpiece, the shaking component works automatically to automatically clean the debris on the surface of the annular workpiece, reducing the workload of the operator and ensuring the processing quality of the annular workpiece.

[0056] Example 2: Refer to Figure 1 , Figure 4 , Figure 7 , Figure 9 and Figure 10 A rotary automated CNC lathe, based on embodiment 1, further includes a clamping assembly comprising a mounting frame 4 fixed on a rotary seat 2, a second motor 401 fixed on the mounting frame 4, a screw 402 rotatably connected to the output shaft of the second motor 401 on the mounting frame 4, a first sleeve 403 threadedly connected to the screw 402, a connecting plate 404 provided on the first sleeve 403, a sleeve 405 rotatably connected to the connecting plate 404, and the end of the sleeve 405 away from the connecting plate 404 slidably connected to the clamping plate 3.

[0057] Specifically, when the clamping assembly is working, it controls the operation of the second motor 401. The output shaft of the second motor 401 drives the screw 402 to rotate, and the first sleeve 403 moves along the axial direction of the screw 402. The first sleeve 403 drives the clamping plate 3 to move through the connecting plate 404 and the sleeve 405, so that the clamping plate 3 clamps the annular workpiece placed on the rotating seat 2.

[0058] Example 3: Reference Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 A rotary automated CNC lathe, based on embodiment 2, further includes a fixed plate 5 fixedly mounted on the lower side of the first sleeve 403, a sliding rod 501 slidably connected to the fixed plate 5, a connecting plate 6 fixedly mounted on one end of the sliding rod 501, a first elastic element 502 sleeved on the outer side of the sliding rod 501 with both ends connected to the fixed plate 5 and the connecting plate 6 respectively, the first elastic element 502 being configured as a spring, a plurality of unequally spaced elastic telescopic inserts 601 being provided on the connecting plate 6, an insertion hole 2031 cooperating with the elastic telescopic inserts 601 being provided on the upper rotating plate 203, and a pressing slope being provided on the lower side of the end of the elastic telescopic insert 601.

[0059] Specifically, when the first sleeve 403 moves axially along the screw 402, the first sleeve 403 drives the elastic telescopic rod 601 on the connecting plate 6 to move to the upper rotating plate 203, so that the elastic telescopic rod 601 is inserted into the insertion hole 2031, fixing the position of the upper rotating plate 203 at this time, thereby effectively supporting the placed annular workpiece and preventing the upper end of the annular workpiece from shifting downward when it is subjected to cutting force, which would affect the processing quality of the annular workpiece; and multiple elastic telescopic rods 601 are unequally spaced on the connecting plate 6, so that at least one elastic telescopic rod 601 is always aligned with the insertion hole 2031 and inserted, while the remaining elastic telescopic rods 601 that are not aligned with the insertion hole 2031 automatically retract, thereby ensuring the stable support state of the upper rotating plate 203 for the annular workpiece.

[0060] Example 4: Reference Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 9 A rotary automated CNC lathe, based on embodiment 3, further includes a rotating mechanism comprising a connecting frame 7 mounted on a mounting frame 4, a third motor 701 fixed on the connecting frame 7, and an output shaft of the third motor 701 connected to a drive rod 702 connected to a sleeve 405.

[0061] Specifically, when the rotating mechanism is working, it controls the operation of the third motor 701, so that the output shaft of the third motor 701 drives the drive rod 702 to rotate. The drive rod 702 drives the sleeve 405, which is slidably connected to it, to rotate through the guide bar, thereby causing the annular workpiece held by the clamping plate 3 at the end of the sleeve 405 to rotate.

[0062] Example 5: Refer to Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 A rotary automated CNC lathe, based on embodiment 4, further includes a vibration assembly comprising a second support plate 11 fixed on a mounting frame 4, a reciprocating lead screw 111 rotatably connected to the second support plate 11, a lifting rod 112 slidably connected to the reciprocating lead screw 111 and rotatably connected to the connecting frame 7, a secondary bevel gear 1121 provided at the top of the lifting rod 112, a first support plate 8 fixed on the connecting frame 7 and rotatably connected to the secondary bevel gear 1121, an incomplete bevel gear 7011 meshing with the secondary bevel gear 1121 connected to the output shaft of the third motor 701, a second sleeve 113 threadedly connected to the outer side of the reciprocating lead screw 111, and the second sleeve 113 fixedly connected to the connecting frame 7.

[0063] Furthermore, telescopic tubes 12 are provided between the mounting bracket 4 and the connecting bracket 7, as well as between the connecting plate 404 and the first sleeve 403.

[0064] Specifically, when the output shaft of the third motor 701 rotates, the outer incomplete bevel gear 7011 meshes with the secondary bevel gear 1121 at the end of the lifting rod 112. The incomplete bevel gear 7011 and the secondary bevel gear 1121 have different numbers of teeth, so that when the incomplete bevel gear 7011 rotates half a turn, the secondary bevel gear 1121 can drive the secondary bevel gear 1121 to rotate multiple turns. The lifting rod 112 drives the reciprocating screw 111 to rotate. When the reciprocating screw 111 rotates, the second sleeve 113 first moves upward along its axial direction, causing the clamping plate 3 to move upward when it rotates the annular workpiece. After the second sleeve 113 moves to the upper end of the reciprocating screw 111, it automatically moves downward along its track groove, so that the second sleeve 113 drives the annular workpiece in the clamping position to shake up and down through the connecting frame 7, shaking off the debris generated during the processing of the outer side of the annular workpiece, and avoiding affecting the cutting operation of the processing unit on the annular workpiece.

[0065] Example 6: Refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 11A rotary automated CNC lathe, based on embodiment 5, further includes a take-up rod 9 fixed to the bottom of the reciprocating lead screw 111, a first drum 901 on the take-up rod 9, a first pull rope 9011 wound around the first drum 901, and the end of the first pull rope 9011 away from the first drum 901 connected to the connecting plate 6. A second drum 902 is also provided on the take-up rod 9, and a second pull rope 9021 is wound around the second drum 902. The end of the second pull rope 9021 away from the second drum 902 passes through the mounting frame 4 and the upper rotating plate 203 and is connected to a slider 1001. A groove 10 for sliding the slider 1001 is provided on the upper rotating plate 203. A second elastic element 1002 is provided between the inner wall of the groove 10 and the slider 1001. The second elastic element 1002 is a spring.

[0066] Specifically, when the vibrating component is working, the reciprocating screw 111 rotates, which drives the winding rod 9 to rotate. The first drum 901 on the winding rod 9 winds up the first pull rope 9011, and the second drum 902 winds up the second pull rope 9021. When the second pull rope 9021 is wound up, it first drives the slider 1001 to move down in the slide groove 10, and the second elastic element 1002 is compressed. When the first pull rope 9011 is wound up, it drives the elastic telescopic rod 601 to move out of the insertion hole 2031 through the connecting plate 6. After the elastic telescopic rod 601 moves out of the insertion hole 2031, the first pull rope 9011 pulls down on the upper rotating plate 203 through the slider 1001, and the elastic telescopic rod 202 is further compressed, causing the upper rotating plate 203 to move down. 03. The downward movement of the ring-shaped workpiece will not obstruct the rotation of the ring-shaped workpiece. After the third motor 701 drives the upper and lower ends of the ring-shaped workpiece to change positions through the clamping plate 3, the incomplete bevel gear 7011 no longer meshes with the secondary bevel gear 1121, the winding rod 9 no longer pulls the connecting plate 6 and the upper rotating plate 203, the elastic telescopic rod 202 pushes the upper rotating plate 203 upward, so that the top surface of the upper rotating plate 203 abuts against the bottom surface of the ring-shaped workpiece, and the elastic telescopic insertion rod 601 is reset and re-inserted into the insertion hole 2031, fixing the height of the upper rotating plate 203 at this time, so that the upper rotating plate 203 supports and limits the bottom of the ring-shaped workpiece, effectively preventing the ring-shaped workpiece from shifting downward under force during cutting and ensuring the processing quality of the ring-shaped workpiece.

[0067] Example 7: Refer to Figure 1 and Figure 4 A rotary automated CNC lathe, based on embodiment 6, further includes a machining section comprising a first hydraulic cylinder 13 fixed on a frame 1, the piston rod of the first hydraulic cylinder 13 being connected to a movable seat 131 slidably connected to the frame 1, a second hydraulic cylinder 132 being fixed on the movable seat 131, and the piston rod of the second hydraulic cylinder 132 being connected to a machining tool holder 133.

[0068] Specifically, when the machining unit is working, the first hydraulic cylinder 13 and the second hydraulic cylinder 132 are engaged until the machining tool holder 133 is placed on the upper side of the annular workpiece and abuts against the upper side wall of the annular workpiece. At this time, the first motor 101 is controlled to run, and the first motor 101 drives the annular workpiece held on the rotating seat 2 to rotate, thereby realizing the cutting work on the annular workpiece.

[0069] This invention also discloses a method for using a rotary automated CNC lathe, comprising the following steps:

[0070] S1: The ring-shaped workpiece to be processed is placed on the rotating seat 2. The upper rotating plate 203 is pressed by the elastic telescopic rod 202 and moves relative to the lower rotating plate 201. The elastic telescopic rod 202 deforms and thus buffers and unloads the force of the ring-shaped workpiece as it is lowered.

[0071] S2: Subsequently, the staff controls the clamping mechanism to work. The output shaft of the second motor 401 drives the screw 402 to rotate. The first sleeve 403 moves along the axial direction of the screw 402. The first sleeve 403 drives the clamping plate 3 to move through the connecting plate 404 and the sleeve 405, so that the clamping plate 3 clamps the annular workpiece placed on the rotating seat 2.

[0072] When the first sleeve 403 moves, it drives the elastic telescopic rod 601 on the connecting plate 6 to move, so that the elastic telescopic rod 601 is inserted into the insertion hole 2031 of the upper rotating plate 203, and the height position of the upper rotating plate 203 is fixed at this time.

[0073] S3: Then the operator controls the machining department to work, so that the first hydraulic cylinder 13 and the second hydraulic cylinder 132 cooperate until the machining tool holder 133 is placed on the upper side of the annular workpiece and abuts against the upper side wall of the annular workpiece. At this time, the operator controls the first motor 101 to run. The first motor 101 drives the annular workpiece clamped on the rotating seat 2 to rotate, thereby realizing the cutting work of the annular workpiece.

[0074] S4: After the cutting of the upper end of the ring workpiece is completed, the operator controls the third motor 701 to run. The output shaft of the third motor 701 drives the sleeve 405 to rotate through the drive rod 702, so that the sleeve 405 rotates the ring workpiece in the clamping plate 3.

[0075] S5: When the output shaft of the third motor 701 rotates, the outer incomplete bevel gear 7011 meshes with the secondary bevel gear 1121 at the end of the lifting rod 112, and the lifting rod 112 drives the reciprocating screw 111 to rotate. When the reciprocating screw 111 rotates, the second sleeve 113 first moves upward along its axial direction. After the second sleeve 113 moves to the upper end of the reciprocating screw 111, it automatically moves downward along its track groove, so that the second sleeve 113 drives the ring workpiece in the clamp to reciprocate up and down through the connecting frame 7, and shakes off the debris generated during the processing of the outer side of the ring workpiece.

[0076] When the reciprocating screw 111 rotates, it drives the winding rod 9 to rotate. The first drum 901 on the winding rod 9 winds up the first pull rope 9011, and the second drum 902 winds up the second pull rope 9021. When the second pull rope 9021 is wound up, it first drives the slider 1001 to move down in the slide groove 10, and the second elastic element 1002 is compressed. When the first pull rope 9011 is wound up, it drives the elastic telescopic rod 601 to move out of the insertion hole 2031 through the connecting plate 6. After the elastic telescopic rod 601 moves out of the insertion hole 2031, the first pull rope 9011 pulls down the upper rotating plate 203 through the slider 1001, and the elastic telescopic rod 202 is further compressed, so that the upper rotating plate 203 moves down and does not obstruct the flipping ring workpiece.

[0077] S6: After the third motor 701 drives the upper and lower ends of the ring workpiece to change positions through the clamping plate 3, the incomplete bevel gear 7011 no longer meshes with the secondary bevel gear 1121, the winding rod 9 no longer pulls the connecting plate 6 and the upper rotating plate 203, the elastic telescopic rod 202 pushes the upper rotating plate 203 to move upward, so that the top surface of the upper rotating plate 203 abuts against the bottom surface of the ring workpiece, and the elastic telescopic insertion rod 601 is re-inserted into the insertion hole 2031, fixing the height of the upper rotating plate 203 at this time, so that the upper rotating plate 203 supports and limits the bottom of the ring workpiece, and then the machining department performs cutting work on the upper end of the ring workpiece.

8. A method of using the rotary automated CNC lathe according to claim 7, characterized in that, Includes the following steps: S1: Place the ring-shaped workpiece to be processed on the rotating seat (2). The upper rotating plate (203) is pressed by the elastic telescopic rod (202) to move relative to the lower rotating plate (201). The elastic telescopic rod (202) deforms and thus buffers and unloads the force of the ring-shaped workpiece as it is lowered. S2: Subsequently, the staff controls the clamping mechanism to work. The output shaft of the second motor (401) drives the screw (402) to rotate. The first sleeve (403) moves along the axial direction of the screw (402). The first sleeve (403) drives the clamping plate (3) to move through the connecting plate (404) and the sleeve (405), so that the clamping plate (3) clamps the annular workpiece placed on the rotating seat (2). When the first sleeve (403) moves, it drives the elastic telescopic rod (601) on the connecting plate (6) to move, so that the elastic telescopic rod (601) is inserted into the insertion hole (2031) of the upper rotating plate (203), and the height position of the upper rotating plate (203) is fixed at this time. S3: Then the operator controls the machining department to work, so that the first hydraulic cylinder (13) and the second hydraulic cylinder (132) cooperate until the machining tool holder (133) is placed on the upper side of the ring workpiece and abuts against the upper side wall of the ring workpiece. At this time, the first motor (101) is controlled to run. The first motor (101) drives the ring workpiece clamped on the rotating seat (2) to rotate, thereby realizing the cutting work of the ring workpiece. S4: After the cutting of the upper end of the ring workpiece is completed, the operator controls the third motor (701) to run. The output shaft of the third motor (701) drives the sleeve (405) to rotate through the drive rod (702), so that the sleeve (405) rotates the ring workpiece in the clamping plate (3). S5: When the output shaft of the third motor (701) rotates, the outer incomplete bevel gear (7011) meshes with the secondary bevel gear (1121) at the end of the lifting rod (112), and the lifting rod (112) drives the reciprocating screw (111) to rotate. When the reciprocating screw (111) rotates, the second sleeve (113) first moves upward along the axial direction of the reciprocating screw (111). After the second sleeve (113) moves to the upper end of the reciprocating screw (111), it automatically moves downward along the track groove of the reciprocating screw (111), so that the second sleeve (113) drives the ring workpiece in the clamp to shake up and down through the connecting frame (7), and shakes off the debris generated during the processing of the outer side of the ring workpiece. When the reciprocating screw (111) rotates, it drives the winding rod (9) to rotate. The first drum (901) on the winding rod (9) winds up the first pull rope (9011), and the second drum (902) winds up the second pull rope (9021). When the second pull rope (9021) is wound up, it first drives the slider (1001) to move down in the groove (10), and the second elastic element (1002) is compressed. When the first pull rope (9011) is wound up, it drives the elastic telescopic rod (601) to move out of the insertion hole (2031) through the connecting plate (6). After the elastic telescopic rod (601) moves out of the insertion hole (2031), the first pull rope (9011) pulls down the upper rotating plate (203) through the slider (1001), and the elastic telescopic rod (202) is further compressed, so that the upper rotating plate (203) moves down and does not obstruct the flipping ring workpiece. S6: After the third motor (701) drives the upper and lower ends of the ring workpiece to change positions through the clamping plate (3), the incomplete bevel gear (7011) no longer meshes with the secondary bevel gear (1121), the winding rod (9) no longer pulls the connecting plate (6) and the upper rotating plate (203), the elastic telescopic rod (202) pushes the upper rotating plate (203) to move upward, so that the top surface of the upper rotating plate (203) abuts against the bottom surface of the ring workpiece, and the elastic telescopic insert (601) is re-inserted into the insert hole (2031) to fix the height of the upper rotating plate (203) at this time, so that the upper rotating plate (203) supports and limits the bottom of the ring workpiece. Then the machining department performs cutting work on the upper end of the ring workpiece.
