The spiral groove of the screw restricts the cross plate so that the cross plate drives the cutting die set to move up and down without offsetting, thereby preventing the turning equipment from offsetting when cutting the curved surface of the tubular workpiece, resulting in poor positioning of the equipment for cutting the curved surface of the tubular workpiece.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-Figure 7 One embodiment of the present invention is: a turning device for curved surface processing, comprising a frame plate 1, a bottom plate 2 is fixed on the top surface of the frame plate 1, a circular hole is opened in the middle of the top surface of the bottom plate 2, a motor 3 is fixedly installed at the bottom end of the frame plate 1, an I-shaped disc 4 is rotatably installed on the inner wall of the circular hole of the bottom plate 2, the middle of the bottom surface of the I-shaped disc 4 is fixedly connected to the top surface of the rotating shaft of the motor 3, and a clamping module 5 is fixedly installed on the top surface of the I-shaped disc 4;

[0030] A Z-shaped frame 6 is fixedly installed on the top surface of the bottom plate 2, and the Z-shaped frame 6 is located on the left side of the clamping module 5. A convex ring 9 is fixed on the top surface of the bottom plate 2. A screw 10 is rotatably installed on the top of the Z-shaped frame 6. The bottom surface of the screw 10 is rotatably connected to the top surface of the convex ring 9. An electric telescopic rod 11 is fixedly installed on the bottom end of the frame plate 1. The electric telescopic rod 11 penetrates and is fixedly installed on the bottom surface of the bottom plate 2. The electric telescopic rod 11 is located on the left side of the motor 3. A block 12 is fixed on the top surface of the telescopic end of the electric telescopic rod 11. A cross plate 13 is fixed on the right side of the block 12. A spiral hole is provided on the top surface of the cross plate 13. The inner wall of the spiral hole of the cross plate 13 is meshed with the spiral groove of the screw 10. A cutting module 14 is fixedly installed on the top surface of the cross plate 13. The cutting module 14 Located on the right side of the Z-shaped frame 6, the cutting module 14 includes a servo electric cylinder and a cutting head. The servo electric cylinder is fixedly installed on the top surface of the horizontal plate 13, and the cutting head is fixedly installed on the right side of the telescopic end of the servo electric cylinder. The curved surface of the workpiece clamped by the clamping module 5 is on the movement track of the cutting head of the cutting module 14. The cutting module 14 extends the cutting head during the movement to cut the curved surface of the tubular workpiece clamped by the clamping module 5. During the up and down reciprocating movement of the cutting module 14, the spiral groove of the screw 10 restricts the horizontal plate 13, so that the horizontal plate 13 will not deviate when driving the cutting module 14 to reciprocate up and down, thereby avoiding the deviation of the turning equipment when cutting the curved surface of the tubular workpiece, resulting in poor equipment positioning and cutting effect of the tubular workpiece curved surface;

[0031] An anti-stuck component is arranged in the middle of the bottom surface of the transverse plate 13, and the anti-stuck component includes a T-shaped plate 15, which is fixed in the middle of the bottom surface of the transverse plate 13, an arc plate 16 is fixed on the right side of the T-shaped plate 15, and a strip block 17 is fixed on the bottom of the left side of the T-shaped plate 15. The strip block 17 is arranged in the spiral groove of the screw 10, and the strip block 17 reciprocates downward in the spiral groove of the screw 10. During the reciprocating movement of the strip block 17 up and down, the strip block 17 sweeps away the cutting debris in the screw 10, so that there is no cutting debris in the spiral groove of the screw 10, so as to avoid the cutting debris adhering to the screw 10 and causing the equipment to jam when the turning equipment is cutting the curved surface of the workpiece.

[0032] When in use, the frame plate 1 supports the bottom plate 2, the bottom plate 2 supports the I-shaped disc 4, the I-shaped disc 4 supports the clamping module 5, the staff puts the tubular workpiece in the clamping module 5, the clamping module 5 clamps the tubular workpiece, and starts the motor 3 on the frame plate 1, the motor 3 shaft starts to rotate forward, the motor 3 shaft drives the I-shaped disc 4 to rotate forward, the I-shaped disc 4 drives the clamping module 5 to rotate forward, and the clamping module 5 drives the tubular workpiece to rotate forward. During the cutting process of the curved surface of the tubular workpiece, the cutting head of the equipment is prone to deviation, which leads to poor effect of positioning and cutting the curved surface of the tubular workpiece by the turning equipment. At this time, the staff starts the electric telescopic rod 11 on the frame plate 1, and the telescopic end of the electric telescopic rod 11 drives the block 12 to move up and down, and the block 12 drives the cross plate 13 to move up and down. The bottom plate 2 supports the convex ring 9, and the spiral hole of the cross plate 13 reciprocates upward in the spiral groove of the screw 10. The screw 10 reciprocates forward and backward in the convex ring 9. At the same time, the screw 10 reciprocates forward and backward in the Z-shaped frame 6. The cross plate 13 drives the cutting module 14 to reciprocate up and down. During the movement, the cutting module 14 extends the cutting head to cut the curved surface of the tubular workpiece clamped by the clamping module 5, so that during the reciprocating movement of the cutting module 14 up and down, the spiral groove of the screw 10 restricts the cross plate 13, so that the cross plate 13 will not deviate when driving the cutting module 14 to reciprocate up and down, thereby preventing the equipment from deviating when cutting the curved surface of the tubular workpiece, thereby avoiding the problem of poor positioning of the equipment and cutting the curved surface of the tubular workpiece caused by the deviation of the turning equipment when cutting the curved surface of the tubular workpiece.

[0033] While the block 12 drives the cross plate 13 to move back and forth up and down, the cross plate 13 drives the T-shaped plate 15 to move back and forth up and down, and the T-shaped plate 15 drives the arc plate 16 to move back and forth up and down. During the process of the arc plate 16 moving back and forth up and down, the arc surface of the arc plate 16 prevents the chips cut by the equipment from splashing into the spiral groove of the screw 10. At the same time, the T-shaped plate 15 drives the bar 17 to move back and forth up and down, and the bar 17 moves back and forth downward in the spiral groove of the screw 10, so that during the process of the bar 17 moving back and forth up and down, the bar 17 sweeps away the cutting chips in the screw 10, leaving no cutting chips in the spiral groove of the screw 10, preventing cutting chips from being present in the screw 10 in the equipment, thereby avoiding the problem of cutting chips adhering to the screw 10 and causing the equipment to jam when the turning equipment cuts the curved surface of the workpiece.

[0034] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a wall wiping device 7 is provided on the right side of the horizontal plate 13, and the wall wiping device 7 includes a ring strip plate 71, two slide bars 72, two round blocks 73, two springs 74 and two sponge blocks 75. The ring strip plate 71 is fixed to the right side of the horizontal plate 13, and slide holes are provided on the front and back sides of the ring strip plate 71. The two slide bars 72 are slidably mounted on the inner walls of the two slide holes of the ring strip plate 71, and the two round blocks 73 are fixed at one end of the two slide bars 72 away from each other. One end of the two springs 74 is fixed to the two round blocks 73. Opposite, the other ends of the two springs 74 away from the two round blocks 73 are fixed on the outer wall of the annular plate 71, and the two sponge blocks 75 are fixed on the opposite sides of the two slide bars 72. The two springs 74 are sleeved on the outer walls of the two slide bars 72. The two sponge blocks 75 are located on the front and back sides of the inside of the annular plate 71. Under the elastic force of the spring 74, the sponge blocks 75 are attached to the rotating tubular workpiece surface and wiped, so that the tubular workpiece surface is wiped clean by the sponge blocks 75, so as to avoid foreign matter attached to the tubular workpiece surface when the turning equipment is cutting the workpiece surface, causing the equipment cutting accuracy to decrease.

[0035] The wall wiping device 7 also includes a rectangular plate 76, a U-shaped rod 77, a circular tube 78 and an annular brush 79. The rectangular plate 76 is fixed on the right side of the annular plate 71, the U-shaped rod 77 is fixed on the front and back sides of the rectangular plate 76, the circular tube 78 is fixed on the outer wall of the U-shaped rod 77, and the annular brush 79 is fixed on the left side of the circular tube 78. The workpiece clamped by the clamping module 5 is on the movement trajectory of the annular brush 79. During the up and down reciprocating movement of the annular brush 79, the annular brush 79 brushes off the cutting debris remaining on the curved surface of the tubular workpiece, so as to avoid the residual cutting debris on the curved surface of the tubular workpiece when the turning equipment is cutting the curved surface of the workpiece, resulting in poor processing effect of the equipment.

[0036] A stabilizing device 8 is arranged on the right side of the wall-wiping device 7, and the stabilizing device 8 comprises a fork plate 81, an L-shaped frame 82, a plurality of semi-arc blocks 83 and a roller 84. The fork plate 81 is fixed on the right side of the rectangular plate 76, the L-shaped frame 82 is fixed on the top surface of the bottom plate 2, the L-shaped frame 82 is located on the right side of the clamping module 5, a plurality of semi-arc blocks 83 are fixed on the left side of the L-shaped frame 82, and the roller 84 is rotatably mounted on the front and back sides of the inner wall of the fork plate 81, a plurality of arc grooves are provided on the outer wall of the roller 84, and a plurality of semi-arc blocks 83 are all on the arc groove movement trajectory of the roller 84. During the rotation of the roller 84, the arc groove of the roller 84 is stuck on the semi-arc block 83, and the semi-arc block 83 limits the roller 84. The friction force of the roller 84 reduces the shaking generated when the ring plate 71 moves up and down, so as to avoid the severe shaking of the turning equipment when cutting the curved surface of the workpiece, resulting in poor processing accuracy of the equipment.

[0037] The stabilizing device 8 also includes two ring frames 85, a cylinder 86, a spring 87, a short rod 88, an arc baffle 89 and an arc-shaped rubber block 810. The two ring frames 85 are fixed to the top surface of the fork plate 81, the cylinder 86 is fixedly mounted on the inner wall of the two ring frames 85, one end of the spring 87 is fixed to the left side of the inner wall of the cylinder 86, the short rod 88 is fixed to the other end of the spring 87 away from the cylinder 86, the outer wall of the short rod 88 is slidably connected to the inner wall of the cylinder 86, the arc baffle 89 is fixed to the left side of the short rod 88, and the arc-shaped rubber block 810 is fixed to the inner wall of the cylinder 86. Block 810 is fixed in the middle of the left side of the arc baffle 89. The workpiece clamped by the clamping module 5 is on the movement trajectory of the arc-shaped rubber block 810. The left side of the arc-shaped rubber block 810 is set as a smooth surface. The arc-shaped rubber block 810 is tightly attached to the rotating tubular workpiece, so that when the cutting head of the cutting module 14 cuts the curved surface of the tubular workpiece, the arc-shaped rubber block 810 is against one side of the rotating tubular workpiece, so as to avoid uneven force on the curved surface of the tubular workpiece when the turning equipment cuts the curved surface of the workpiece, causing deformation of the curved surface of the tubular workpiece.

[0038] While the block 12 drives the cross plate 13 to move up and down reciprocatingly, the cross plate 13 drives the annular strip plate 71 to move up and down reciprocatingly, the annular strip plate 71 drives the slide bar 72 to move up and down reciprocatingly, the slide bar 72 drives the round block 73 to move up and down reciprocatingly, the round block 73 drives the spring 1 74 to move up and down reciprocatingly, and at the same time, the slide bar 72 drives the sponge block 75 to move up and down reciprocatingly. During the up and down reciprocating movement of the sponge block 75, the sponge block 75 contacts the rotating tubular workpiece. Under the action of the extrusion force, the slide bar 72 The ring plate 71 slides, and the slide rod 72 drives the round block 73 to move. The spring 74 on the round block 73 is stretched. Under the elastic force of the spring 74, the sponge block 75 is attached to the rotating tubular workpiece surface for wiping, so that the tubular workpiece surface is wiped clean by the sponge block 75, thereby preventing foreign matter from being attached to the tubular workpiece surface when the equipment is cutting the tubular workpiece surface, thereby avoiding the problem of reduced cutting accuracy of the equipment due to foreign matter being attached to the tubular workpiece surface when the turning equipment is cutting the workpiece surface.

[0039] While the cross plate 13 drives the annular plate 71 to move reciprocatingly up and down, the annular plate 71 drives the rectangular plate 76 to move reciprocatingly up and down, the rectangular plate 76 drives the U-shaped rod 77 to move reciprocatingly up and down, the U-shaped rod 77 drives the round tube 78 to move reciprocatingly up and down, and the round tube 78 drives the annular brush 79 to move reciprocatingly up and down, so that in the process of the annular brush 79 reciprocating up and down, the annular brush 79 brushes off the cutting debris remaining on the curved surface of the tubular workpiece, preventing the equipment from having cutting debris remaining on the curved surface of the tubular workpiece when cutting the curved surface of the tubular workpiece, thereby avoiding the problem of poor processing effect of the equipment caused by cutting debris remaining on the curved surface of the tubular workpiece when the turning equipment cuts the curved surface of the workpiece.

[0040] When the annular plate 71 drives the rectangular plate 76 to move up and down, the rectangular plate 76 drives the fork plate 81 to move up and down, and the fork plate 81 drives the roller 84 to move up and down. At the same time, the bottom plate 2 supports the L-shaped frame 82, and the L-shaped frame 82 supports the semi-arc block 83. Under the action of friction, the roller 84 rolls up and down on the L-shaped frame 82. During the rotation of the roller 84, the arc groove of the roller 84 is stuck on the semi-arc block 83, so that the semi-arc block 83 limits the roller 84. The friction force of the roller 84 slows down the shaking generated when the annular plate 71 moves up and down, preventing the equipment from shaking violently during operation, thereby avoiding the problem of poor processing accuracy of the equipment caused by the severe shaking of the turning equipment when cutting the curved surface of the workpiece.

[0041] While the rectangular plate 76 drives the fork plate 81 to move back and forth up and down, the fork plate 81 drives the ring frame 85 to move back and forth up and down, the ring frame 85 drives the cylinder 86 to move back and forth up and down, the cylinder 86 drives the spring 2 87 to move back and forth up and down, the cylinder 86 drives the short rod 88 to move back and forth up and down, the short rod 88 drives the arc baffle 89 to move back and forth up and down, the arc baffle 89 drives the arc-shaped rubber block 810 to move back and forth up and down, and in the process of the arc-shaped rubber block 810 moving back and forth up and down, the arc-shaped rubber block 810 contacts the rotating tubular workpiece under the action of the extrusion force. The short rod 88 slides rightward in the cylinder 86, and the spring 2 87 of the cylinder 86 begins to contract. Under the elastic force of the spring 2 87, the arc-shaped rubber block 810 is tightly attached to the rotating tubular workpiece, so that when the cutting head of the cutting module 14 cuts the curved surface of the tubular workpiece, the arc-shaped rubber block 810 is against one side of the rotating tubular workpiece, preventing the curved surface of the tubular workpiece from being subjected to uneven force when the equipment cuts the curved surface of the tubular workpiece, thereby avoiding the problem of deformation of the curved surface of the tubular workpiece caused by uneven force on the curved surface of the tubular workpiece when the turning equipment cuts the curved surface of the workpiece.
