[0001] The invention relates to the technical field of workpiece processing, in particular to a device used for turning processing. Background Art

[0011] Preferably, a fourth motor is installed on the right surface of the first mounting frame, and the output end of the fourth motor slides through the right surface of the first mounting frame and extends to the left side.

When all the clamping columns are fully retracted inward, the end of the workpiece can be clamped, and only three clamping columns need to be tightly in contact with the surface of the workpiece to complete the clamping and fixing of the workpiece. Therefore, this device is suitable for processing workpieces of most shapes and has high practicality.

[0018] 3. When the workpiece and the blank are fixed by the clamping column, rotate the adjusting screw on the top of the mounting block. At this time, since the fastening block is limited by the guide rod, it will move in a straight line toward the center of the rotating disk. When the fastening block and the gear sleeve on the surface of the fixed disk are engaged, since the mounting block and the rotating disk are in a fixed connection state, the rotating disk and the fixed disk will not rotate at this time, ensuring the stability of the clamping column. The design has a simple structure and further improves the clamping effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 7The present invention provides a technical solution: a device for turning processing, comprising a workbench 1, an extrusion mechanism 5 is arranged at the top of the workbench 1 near the left side, a driving mechanism 3 is arranged at the top of the workbench 1 near the right side, a clamping mechanism 4 is arranged on the left side of the driving mechanism 3, a replicating mechanism 2 is arranged between the driving mechanism 3 and the extrusion mechanism 5, the replicating mechanism 2 comprises a second motor 201, a second screw rod 202 is fixedly connected to the output end of the second motor 201, an inner sleeve 203 is provided on the outer surface of the second screw rod 202, an outer sleeve 204 is rotatably connected to the outer surface of the inner sleeve 203, a T-shaped piece 205 is fixedly connected to the position above the outer surface of the outer sleeve 204, and the T-shaped piece 205 is fixedly connected to the position above the outer surface of the outer sleeve 204. The T-shaped piece 205 is arranged at an angle. When the workpiece and the blank are installed, the guide disc 207 will be located obliquely above the surface of the new workpiece, and the milling cutter disc 209 will be located obliquely below the blank and the two will contact each other. Then the third motor 208 is started to drive the milling cutter disc 209 to rotate at a high speed to cut the surface of the blank. During this process, the counterweight block 206 will cause the T-shaped piece 205 to always be in an inclined state, and the outer sleeve 204 at the bottom of the T-shaped piece 205 will adaptively rotate outside the inner sleeve 203 on the surface of the second screw rod 202. As the surface of the blank is gradually cut off, the guide disc 207 will fit the surface of the new workpiece, so that the milling cutter disc 209 can no longer continue to contact the surface of the blank.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, a third motor 208 is installed on the left surface of the T-shaped piece 205 near the top, and the output end of the third motor 208 slides through the outer surface of the T-shaped piece 205 and extends to the other side. The output end of the third motor 208 is fixedly connected to a milling cutter disc 209, and a guide disc 207 is rotatably connected to the right surface of the T-shaped piece 205 near the bottom. A counterweight block 206 is fixedly connected to the left surface of the T-shaped piece 205 near the bottom. During the process of the milling cutter disc 209 processing the blank, the second motor 201 is started at the same time to drive the second screw rod 202 to rotate. At this time, the second screw rod 202 will drive the inner sleeve 203 to move back and forth left and right, so that the milling cutter disc 209 will repeatedly cut the surface of the blank until the guide disc 207 is fully in contact with each position of the surface of the new workpiece. At this time, the blank is cut into a state consistent with the shape of the new workpiece, and the turning operation is completed. The design structure is simple and novel, has a strong replica effect, and can be operated without professional technology, and is highly practical.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, the driving mechanism 3 includes a first mounting frame 301, which is fixedly connected to the top of the workbench 1 near the right edge, and the second motor 201 is installed on the right surface of the first mounting frame 301 near the middle position, and the output end of the second motor 201 slides through the right surface of the first mounting frame 301 and extends to the left side, and the left surface of the first mounting frame 301 is rotatably connected to two pulleys 303, and the center of the first screw rod 16 is located on the perpendicular bisector of the centers of the two pulleys 303, and the rotation center of the new workpiece and the blank coincides with the center of the two pulleys 303, and the rotation center of the first screw rod 16 is located on the perpendicular bisector of the centers of the new workpiece and the blank, and the centers of the two form an isosceles triangle, and the milling cutter disc 209 and the guide disc 207 are of the same size, so the distances between the edges of the milling cutter disc 209 and the guide disc 207 and the edges of the two pulleys 303 are always equal.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, a fourth motor 302 is installed on the right surface of the first mounting frame 301, and the output end of the fourth motor 302 slides through the right surface of the first mounting frame 301 and extends to the left side. The output end of the fourth motor 302 is fixedly connected to the center of the right surface of one of the pulleys 303, and a transmission belt 304 is connected between the outer surfaces of the two pulleys 303. During the cutting process of the blank, the fourth motor 302 is started at the same time. At this time, the output end of the fourth motor 302 will drive one of the pulleys 303 to rotate, and under the action of the transmission belt 304, the other pulley 303 will follow and rotate synchronously, so that the new workpiece and the blank are in the same direction and speed rotation state, and then the guide disk 207 is in contact with any position of the surface of the new workpiece, thereby ensuring that the blank is cut into a new workpiece state.

[0027] like Figure 1 , Figure 2 and Figure 6As shown, the number of clamping mechanisms 4 is set to two, and the two clamping mechanisms 4 each include a mounting disk 401, and the two mounting disks 401 are respectively fixedly connected to the left surfaces of the two pulleys 303, and the left surfaces of the two mounting disks 401 are fixedly connected with a fixed disk 402, and the left surface of the fixed disk 402 is rotatably connected with a rotating shaft 406, and the left end of the rotating shaft 406 is fixedly connected with a rotating disk 407, and the left surface of the rotating disk 407 is penetrated by a plurality of straight grooves 408, and the plurality of straight grooves 408 are circumferentially distributed on the left surface of the rotating disk 407, and the left surface of the fixed disk 402 is provided with a plurality of arc grooves 403, and the plurality of arc grooves 403 are circumferentially distributed on the left surface of the fixed disk 402, and a clamping column 405 is slidably embedded between the inner surface walls of the straight grooves 408, and the clamping column 405 The right end is slidably inserted into the interior of the arc groove 403. When using this device to turn a new workpiece, first place one end of the new workpiece blank against the rotating disk 407, and then rotate the rotating disk 407. At this time, the straight groove 408 on the surface of the rotating disk 407 will rotate relative to the arc groove 403 on the surface of the fixed disk 402, and the intersection of the two will gradually shift from the outside to the inside, and the movable clamping column 405 between the straight groove 408 and the inner wall of the arc groove 403 will move with the intersection of the two. When all the clamping columns 405 are fully retracted inwardly, the end of the workpiece can be clamped, and only three clamping columns 405 need to be tightly in contact with the surface of the workpiece to complete the clamping and fixing of the workpiece. Therefore, this device is suitable for processing workpieces of most shapes and has high practicality.

[0028] like Figure 1 , Figure 2 and Figure 6 As shown, the top of the rotating disk 407 is fixedly connected with an L-shaped mounting block 409, the top center of the mounting block 409 is threadedly connected with an adjusting screw 410, the bottom end of the adjusting screw 410 is rotatably connected with a fastening block 411, the top of the fastening block 411 is symmetrically fixedly connected with a guide rod 412 near the edge, the outer surface of the guide rod 412 slides through the outer surface of the mounting block 409 and extends upward, the outer surface of the fixed disk 402 is fixedly connected with a gear sleeve 404, the outer surface of the gear sleeve 404 is meshed with the bottom of the fastening block 411, when After the workpiece and the blank are fixed by the clamping column 405, the adjusting screw 410 on the top of the mounting block 409 is rotated. At this time, since the fastening block 411 is limited by the guide rod 412, it will move in a straight line toward the center of the rotating disk 407. When the fastening block 411 and the toothed sleeve 404 on the surface of the fixed disk 402 are engaged, since the mounting block 409 and the rotating disk 407 are in a fixed connection state, the rotating disk 407 and the fixed disk 402 will not rotate at this time, thereby ensuring the stability of the clamping column 405. The design structure is simple and further improves the clamping effect.

[0029] like Figure 1 , Figure 2 and Figure 7 As shown, the extrusion mechanism 5 includes a second mounting frame 501, which is fixedly connected between the movable block 13 and the top of the limit block 14. The right surface of the second mounting frame 501 is rotatably connected to two rotating seats 502 through bearings. The right surface of the rotating seat 502 is fixedly connected to a conical block 503. The first motor 15 is started to drive the first screw rod 16 to rotate. At this time, the movable block 13 will drive the second mounting frame 501 to move toward the first mounting frame 301 under the action of the first screw rod 16. When the sharp end of the conical block 503 is against the other end of the workpiece and the blank, the limit block 14 and the limit groove 12 cooperate to limit the second mounting frame 501 when it moves, thereby improving stability. The conical block 503 and the second mounting frame 501 are connected through the rotating seat 502 and the bearing, so that the conical block 503 can rotate with it when it is against the workpiece and the blank.

[0030] The use method and working principle of this device: When using this device to turn a new workpiece, first place one end of the new workpiece blank against the rotating disk 407, and then rotate the rotating disk 407. At this time, the straight groove 408 on the surface of the rotating disk 407 will rotate relative to the arc groove 403 on the surface of the fixed disk 402, and the intersection of the two will gradually move from the outside to the inside, and the movable clamping column 405 between the inner wall of the straight groove 408 and the arc groove 403 will move with the intersection of the two. When all the clamping columns 405 are fully retracted inward, the end of the workpiece can be clamped, and only three clamping columns 405 need to be tightly in contact with the surface of the workpiece to complete the clamping and fixing of the workpiece. Therefore, this device is suitable for processing workpieces of most shapes and is very practical. The workpiece and the blank are fixed by the clamping column 405, and the adjusting screw 410 on the top of the mounting block 409 is rotated. At this time, since the fastening block 411 is limited by the guide rod 412, it will move linearly toward the center of the rotating disk 407. When the fastening block 411 is engaged with the toothed sleeve 404 on the surface of the fixed disk 402, since the mounting block 409 and the rotating disk 407 are in a fixed connection state, the rotating disk 407 and the fixed disk 402 will not rotate at this time, thereby ensuring the stability of the clamping column 405. The design structure is simple and further improves the clamping effect. Subsequently, the first motor 15 is started to drive the first screw rod 16 to rotate. At this time, the movable block 13 will drive the second mounting frame 501 to move toward the direction of the first mounting frame 301 under the action of the first screw rod 16. When the sharp end of the conical block 503 is against the other end of the workpiece and the blank, the limit block 14 and the limit groove 12 cooperate to limit the second mounting frame 501 when it moves, thereby improving stability. The conical block 503 and the second mounting frame 501 are connected through the rotating seat 502 and the bearing, so the conical block 503 can rotate with the workpiece and the blank when it is against the workpiece and the blank. When the workpiece and the blank are installed, the guide disk 207 will be located obliquely above the surface of the new workpiece, and the milling cutter disk 209 will be located obliquely below the blank and the two will contact each other. Then, the third motor 208 is started to drive the milling cutter disk 209 to rotate at a high speed to cut the surface of the blank. During this process, the counterweight block 206 will cause the T-shaped piece 205 to always be in an inclined state, and the T-shaped piece 205 will be in an inclined state. The outer sleeve 204 at the bottom of the blank 205 will adaptively rotate on the outside of the inner sleeve 203 on the surface of the second screw rod 202. As the surface of the blank is gradually cut off, the guide disc 207 will fit with the surface of the new workpiece, so that the milling cutter disc 209 can no longer continue to contact the surface of the blank. During the process of the milling cutter disc 209 processing the blank, the second motor 201 is started at the same time to drive the second screw rod 202 to rotate. At this time, the second screw rod 202 will drive the inner sleeve 203 to move back and forth left and right, so that the milling cutter disc 209 will repeatedly cut the surface of the blank until the guide disc 207 is fully in contact with every position of the surface of the new workpiece. At this time, the blank is cut into a state consistent with the shape of the new workpiece, and the turning operation is completed. The design structure is simple and novel, and has a strong replica effect.And it can be operated without professional skills, and it is highly practical. During the cutting process of the blank, the fourth motor 302 is started at the same time. At this time, the output end of the fourth motor 302 will drive one of the pulleys 303 to rotate, and under the action of the transmission belt 304, the other pulley 303 will follow and rotate synchronously, so that the new workpiece and the blank are in the same direction and speed rotation state, and then the guide plate 207 and any position of the surface of the new workpiece are in contact, so as to ensure that the blank is cut into a new workpiece state.
