[0003] Turning equipment for surface machining is a very important type of equipment in the field of machining. It is widely used in aerospace, automobile manufacturing, mold processing and other fields. It is mainly used for rotary cutting of various metal and non-metal materials. This equipment effectively improves the machining accuracy and production efficiency of curved surfaces of mechanical parts.

[0004] Patent CN215237852U discloses a gantry turning machine for processing heavy machinery parts, including a turning machine body and a turning head on the turning machine body. The turning head is equipped with a collection component for collecting the chips generated after turning. The collection component has a filter component inside to prevent chips from being thrown out. The outer side of the collection component is equipped with a negative pressure component for sucking the chips into the collection component. When the turning head is turning the product, the negative pressure component is opened to generate negative pressure at the input end of the collection component to absorb the chips. This gantry turning machine for processing heavy machinery parts achieves the effect of preventing chips from contaminating the working environment and preventing chips from damaging the exterior of the product during the turning process by collecting chips through the collection component. The filter component filters the chips collected inside the collection component to prevent chips from splashing out of the collection component and prevents chips from entering the negative pressure component.

[0005] However, the current gantry turning equipment for machining heavy machinery parts has the following problems: When using this gantry turning equipment for machining heavy machinery parts, the cutting head of the equipment is prone to deflection during the cutting process of the curved surface of the tubular workpiece, which leads to poor positioning and cutting effect of the turning equipment on the curved surface of the tubular workpiece. Therefore, we propose a turning equipment for curved surface machining. Summary of the Invention

An anti-jamming component is provided in the middle of the bottom surface of the horizontal plate.

[0008] The anti-jamming component includes a T-shaped plate, which is fixed in the middle of the bottom surface of the horizontal plate. An arc plate is fixed to the right side of the T-shaped plate, and a strip is fixed to the bottom left side of the T-shaped plate. The strip is set in the spiral groove of the screw and removes cutting debris from the screw, so that there are no cutting debris in the spiral groove of the screw.

[0009] A wall-rubbing device is provided on the right side of the horizontal plate, and a stabilizing device is provided on the right side of the wall-rubbing device.

[0010] According to the above technical solution, the cutting module includes a servo electric cylinder and a cutting head. The servo electric cylinder is fixedly installed on the top surface of the horizontal plate, 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 held by the clamping module is on the movement trajectory of the cutting head of the cutting module, and the arc plate is located on the top left side of the workpiece held by the clamping module.

[0011] According to the above technical solution, the wall-wiping device includes a ring plate, two sliding rods, two round blocks, two springs, and two sponge blocks. The ring plate is fixed to the right side of the horizontal plate. Sliding holes are opened on the front and back of the ring plate. The two sliding rods are slidably installed on the inner walls of the two sliding holes of the ring plate. The two round blocks are fixed at the ends of the two sliding rods that are far apart from each other. One end of the two springs is fixed directly opposite the two round blocks. The other end of the two springs that is far away from the two round blocks is fixed on the outer wall of the ring plate. The two sponge blocks are fixed directly opposite the two sliding rods. The sponge blocks are attached to the curved surface of the rotating tubular workpiece to wipe it clean.

[0012] According to the above technical solution, the wall-wiping device further includes a rectangular plate, a U-shaped rod, a round tube, and a ring brush. The rectangular plate is fixed to the right side of the ring plate, the U-shaped rod is fixed to the front and back of the rectangular plate, the round tube is fixed to the outer wall of the U-shaped rod, and the ring brush is fixed to the left side of the round tube. The ring brush brushes off the cutting debris remaining on the curved surface of the tubular workpiece.

[0013] According to the above technical solution, the two springs are connected to the outer walls of the two slide rods, the two sponge blocks are located on the front and back sides inside the ring plate, and the workpiece held by the clamping module is on the movement trajectory of the ring brush.

[0014] According to the above technical solution, the stabilizing device includes a fork plate, an L-shaped frame, several semi-circular blocks, and rollers. The fork plate is fixed to the right side of the rectangular plate, the L-shaped frame is fixed to the top surface of the base plate, and the L-shaped frame is located to the right of the clamping module. Several semi-circular blocks are fixed to the left side of the L-shaped frame. The rollers are rotatably mounted on the front and back of the inner wall of the fork plate. Several arc grooves are opened on the outer wall of the rollers. The arc grooves of the rollers are stuck on the semi-circular blocks, and the semi-circular blocks limit the rollers. The friction of the rollers reduces the shaking caused by the up-and-down movement of the ring plate.

[0015] According to the above technical solution, the stabilizing device further includes two ring frames, a cylinder, a second spring, a short rod, an arc baffle, and an arc-shaped rubber block. The two ring frames are fixed to the top surface of the fork plate, the cylinder is fixedly installed on the inner wall of the two ring frames, one end of the second spring is fixed to the left side of the inner wall of the cylinder, the short rod is fixed to the other end of the second spring away from the cylinder, the outer wall of the short rod is slidably connected to the inner wall of the cylinder, the arc baffle is fixed to the left side of the short rod, and the arc-shaped rubber block is fixed to the middle of the left side of the arc baffle. The arc-shaped rubber block is in close contact with the forward-rotating tubular workpiece, so that when the cutting head of the cutting module cuts the curved surface of the tubular workpiece, the arc-shaped rubber block abuts against one side of the forward-rotating tubular workpiece.

[0016] According to the above technical solution, several of the semi-arc blocks are all on the arc groove movement trajectory of the roller, and the workpiece clamped by the clamping module is on the movement trajectory of the arc-shaped rubber block. The left side of the arc-shaped rubber block is set as a smooth surface.

[0017] This invention provides a turning device for machining curved surfaces. It has the following advantages:

[0018] (1) The present invention uses a Z-shaped frame, a convex ring, a screw, an electric telescopic rod, a block, a horizontal plate, a cutting module, a T-shaped plate, and an arc plate in combination with the strip block. The spiral groove of the screw restricts the horizontal plate, so that the horizontal plate will not deviate when the cutting module moves up and down. This prevents the turning equipment from deviating when cutting the curved surface of the tubular workpiece, resulting in poor positioning and cutting effect of the tubular workpiece. In addition, the strip block removes the cutting chips in the screw, so that there are no cutting chips in the spiral groove of the screw, preventing the cutting chips from adhering to the screw and causing the equipment to jam.

[0019] (2) The present invention, through the setting of the wall wiping device, makes the ring bar plate, slide bar, round block, spring, sponge block, rectangular plate, U-shaped rod and round tube work together with the ring brush. The sponge block is attached to the curved surface of the tubular workpiece in the forward rotation to wipe it clean, so that the curved surface of the tubular workpiece is wiped clean by the sponge block, preventing foreign objects from adhering to the curved surface of the tubular workpiece and causing a decrease in the cutting accuracy of the equipment. In addition, the ring brush brushes off the cutting debris remaining on the curved surface of the tubular workpiece, preventing the cutting debris remaining on the curved surface of the tubular workpiece from causing poor processing effect of the equipment.

[0020] (3) The present invention, through the setting of the stabilizing device, makes the fork plate, L-shaped frame, semi-arc block, roller, ring frame, cylinder, spring two, short rod and arc baffle cooperate with the arc rubber block. The arc groove of the roller is stuck on the semi-arc block, and the semi-arc block limits the roller. The friction of the roller reduces the shaking generated when the ring plate moves up and down, and prevents the equipment from shaking violently, resulting in poor processing accuracy. In addition, the arc rubber block is close to the forward rotating tubular workpiece. When the cutting head of the cutting module cuts the curved surface of the tubular workpiece, the arc rubber block is pressed against one side of the forward rotating tubular workpiece, preventing uneven force on the curved surface of the tubular workpiece from causing deformation of the curved surface of the tubular workpiece.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figures 1-7 One embodiment of the present invention is: a turning device for surface machining, including a frame plate 1, a base plate 2 fixed on the top surface of the frame plate 1, a circular hole in the middle of the top surface of the base plate 2, a motor 3 fixedly installed at the bottom inside the frame plate 1, an I-shaped disc 4 rotatably installed on the inner wall of the circular hole of the base 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;

[0031] A Z-shaped frame 6 is fixedly installed on the top surface of the base plate 2. The Z-shaped frame 6 is located to the left of the clamping module 5. A convex ring 9 is fixedly installed on the top surface of the base plate 2. A screw 10 is rotatably installed at 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 at the bottom of the frame plate 1. The electric telescopic rod 11 passes through and is fixedly installed on the bottom surface of the base plate 2. The electric telescopic rod 11 is located to the left of the motor 3. A block 12 is fixedly installed on the top surface of the telescopic end of the electric telescopic rod 11. A horizontal plate 13 is fixedly installed on the right side of the block 12. A spiral hole is provided on the top surface of the horizontal plate 13. The inner wall of the spiral hole of the horizontal plate 13 meshes with the spiral groove of the screw 10. A cutting module 14 is fixedly installed on the top surface of the horizontal plate 13. 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 extension end of the servo electric cylinder. The curved surface of the workpiece held by the clamping module 5 is on the movement trajectory of the cutting head of the cutting module 14. During the movement, the cutting module 14 extends the cutting head to cut the curved surface of the tubular workpiece held 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 it drives the cutting module 14 to move up and down. This avoids the turning equipment from deviating when cutting the curved surface of the tubular workpiece, resulting in poor positioning and cutting effect of the tubular workpiece.

[0032] An anti-jamming component is provided in the middle of the bottom surface of the horizontal plate 13. The anti-jamming component includes a T-shaped plate 15, which is fixed in the middle of the bottom surface of the horizontal plate 13. An arc plate 16 is fixed to the right side of the T-shaped plate 15, and a strip 17 is fixed to the bottom left side of the T-shaped plate 15. The strip 17 is set in the spiral groove of the screw 10. The strip 17 moves downward and reciprocally in the spiral groove of the screw 10. During the up-and-down reciprocating movement, the strip 17 sweeps away the cutting debris in the screw 10, so that there are no cutting debris in the spiral groove of the screw 10, thus preventing the cutting debris from adhering to the screw 10 and causing the equipment to jam when the turning equipment is cutting the curved surface of the workpiece.

[0033] In use, the frame plate 1 supports the base plate 2, the base plate 2 supports the I-shaped disc 4, and the I-shaped disc 4 supports the clamping module 5. The operator places the tubular workpiece in the clamping module 5, which clamps the workpiece. The motor 3 on the frame plate 1 is then started, and the motor 3's shaft begins to rotate clockwise. The motor 3's shaft drives the I-shaped disc 4 to rotate clockwise, which in turn drives the clamping module 5 to rotate clockwise. The clamping module 5 then drives the tubular workpiece to rotate clockwise. Because the cutting head of the equipment is prone to misalignment during the cutting of the curved surface of the tubular workpiece, resulting in poor positioning and cutting effect, the operator activates the electric telescopic rod 11 on the frame plate 1. The telescopic end of the electric telescopic rod 11 drives the block 12 to move up and down reciprocally, which in turn drives the horizontal plate 13 to move up and down reciprocally. Simultaneously... The base plate 2 supports the convex ring 9. The spiral hole of the horizontal plate 13 moves back and forth in the spiral groove of the screw 10. The screw 10 rotates back and forth in the convex ring 9. At the same time, the screw 10 rotates back and forth in the Z-shaped frame 6. The horizontal plate 13 drives the cutting module 14 to move up and down. During the movement, the cutting module 14 extends the cutting head to cut the curved surface of the tubular workpiece held 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 does not deviate when driving the cutting module 14 to move up and down. This prevents the equipment from deviating when cutting the curved surface of the tubular workpiece, thus avoiding the problem of poor positioning and cutting effect of the tubular workpiece when the turning equipment deviates when cutting the curved surface of the tubular workpiece.

[0034] While the square block 12 drives the horizontal plate 13 to move up and down reciprocally, the horizontal plate 13 drives the T-shaped plate 15 to move up and down reciprocally, and the T-shaped plate 15 drives the arc plate 16 to move up and down reciprocally. During the up and down reciprocating movement of the arc plate 16, the arc surface of the arc plate 16 prevents the cutting debris from splashing into the spiral groove of the screw 10. At the same time, the T-shaped plate 15 drives the strip block 17 to move up and down reciprocally. The strip block 17 moves downwards in the spiral groove of the screw 10, so that the strip block 17 sweeps away the cutting debris in the screw 10 during the up and down reciprocating movement, so that there are no cutting debris in the spiral groove of the screw 10. This prevents the screw 10 in the equipment from having cutting debris, thereby avoiding the problem of 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.

[0035] Please see Figures 1-7In another embodiment of the present invention, based on the above embodiments, a wall-rubbing device 7 is provided on the right side of the horizontal plate 13. The wall-rubbing device 7 includes a ring plate 71, two sliding rods 72, two round blocks 73, two springs 74, and two sponge blocks 75. The ring plate 71 is fixed to the right side of the horizontal plate 13. Sliding holes are provided on the front and back of the ring plate 71. The two sliding rods 72 are slidably installed on the inner walls of the two sliding holes of the ring plate 71. The two round blocks 73 are fixed at the ends of the two sliding rods 72 that are far apart from each other. One end of each of the two springs 74 is fixed to the two round blocks 73. Directly opposite, the other ends of two springs 74, away from the two round blocks 73, are fixed to the outer wall of the ring plate 71. Two sponge blocks 75 are fixed directly opposite the two slide rods 72. The two springs 74 are sleeved on the outer wall of the two slide rods 72. The two sponge blocks 75 are located on the inside front and back sides of the ring plate 71. Under the elastic force of the springs 74, the sponge blocks 75 are attached to the curved surface of the rotating tubular workpiece to wipe it clean, so that the curved surface of the tubular workpiece is wiped clean by the sponge blocks 75. This prevents the cutting accuracy of the equipment from being reduced due to foreign objects adhering to the curved surface of the tubular workpiece when the turning equipment is cutting the curved surface of the workpiece.

[0036] The wall-wiping device 7 also includes a rectangular plate 76, a U-shaped rod 77, a round tube 78, and a ring brush 79. The rectangular plate 76 is fixed to the right side of the ring plate 71, the U-shaped rod 77 is fixed to the front and back of the rectangular plate 76, the round tube 78 is fixed to the outer wall of the U-shaped rod 77, and the ring brush 79 is fixed to the left side of the round tube 78. The workpiece held by the clamping module 5 is on the movement trajectory of the ring brush 79. During the up-and-down reciprocating movement of the ring brush 79, the ring brush 79 brushes off the cutting debris remaining on the curved surface of the tubular workpiece, so as to avoid the poor processing effect caused by the cutting debris remaining on the curved surface of the tubular workpiece when the turning equipment cuts the curved surface of the workpiece.

[0037] A stabilizing device 8 is provided on the right side of the wall-rubbing device 7. The stabilizing device 8 includes a fork plate 81, an L-shaped frame 82, several semi-arc blocks 83, and rollers 84. The fork plate 81 is fixed to the right side of the rectangular plate 76, the L-shaped frame 82 is fixed to the top surface of the base plate 2 and is located on the right side of the clamping module 5. Several semi-arc blocks 83 are fixed to the left side of the L-shaped frame 82. The rollers 84 are rotatably mounted on the front and back of the inner wall of the fork plate 81. Several arc grooves are opened on the outer wall of the rollers 84. Several semi-arc blocks 83 are all on the movement trajectory of the arc grooves of the rollers 84. During the rotation of the rollers 84, the arc grooves of the rollers 84 are stuck on the semi-arc blocks 83. The semi-arc blocks 83 limit the rollers 84. The friction of the rollers 84 reduces the vibration generated when the ring plate 71 moves up and down, and avoids the turning equipment from generating severe vibration when cutting the curved surface of the workpiece, which would cause poor machining accuracy.

[0038] The stabilizing device 8 also includes two ring frames 85, a cylinder 86, a second spring 87, a short rod 88, an arc-shaped 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 installed on the inner wall of the two ring frames 85. One end of the second 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 second 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-shaped baffle 89 is fixed to the left side of the short rod 88. The arc-shaped rubber block 810... Block 810 is fixed to the middle of the left side of the arc baffle 89. The workpiece held by the clamping module 5 is on the movement trajectory of the arc rubber block 810. The left side of the arc rubber block 810 is set as a smooth surface. The arc rubber block 810 is tightly attached to the rotating tubular workpiece. When the cutting head of the cutting module 14 cuts the curved surface of the tubular workpiece, the arc rubber block 810 is pressed against one side of the rotating tubular workpiece to avoid uneven force on the curved surface of the tubular workpiece during the cutting of the workpiece surface by the turning equipment, which would cause deformation of the curved surface of the tubular workpiece.

[0039] While block 12 drives horizontal plate 13 to move up and down reciprocally, horizontal plate 13 drives ring plate 71 to move up and down reciprocally, ring plate 71 drives slide rod 72 to move up and down reciprocally, slide rod 72 drives round block 73 to move up and down reciprocally, round block 73 drives spring 74 to move up and down reciprocally, and at the same time, slide rod 72 drives sponge block 75 to move up and down reciprocally. During the up and down reciprocating movement of sponge block 75, sponge block 75 contacts the forward-rotating tubular workpiece. Under the action of extrusion force, slide rod 72... The ring plate 71 slides, and the slide rod 72 drives the circular block 73 to move. The spring 74 on the circular block 73 is stretched. Under the elastic force of the spring 74, the sponge block 75 is made to stick to the curved surface of the rotating tubular workpiece and wipe it clean. This prevents foreign objects from adhering to the curved surface of the tubular workpiece when the equipment is cutting it, thus avoiding the problem of reduced cutting accuracy caused by foreign objects adhering to the curved surface of the tubular workpiece when the turning equipment is cutting the curved surface of the workpiece.

[0040] While the horizontal plate 13 drives the ring plate 71 to move up and down reciprocally, the ring plate 71 drives the rectangular plate 76 to move up and down reciprocally, the rectangular plate 76 drives the U-shaped rod 77 to move up and down reciprocally, the U-shaped rod 77 drives the round tube 78 to move up and down reciprocally, and the round tube 78 drives the ring brush 79 to move up and down reciprocally. During the up and down reciprocating motion, the ring brush 79 brushes off the cutting debris remaining on the curved surface of the tubular workpiece, preventing the equipment from leaving cutting debris on the curved surface of the tubular workpiece when cutting it. This avoids the problem of poor processing effect caused by the cutting debris remaining on the curved surface of the tubular workpiece when the turning equipment cuts the curved surface of the workpiece.

[0041] While the ring plate 71 drives the rectangular plate 76 to move up and down reciprocally, the rectangular plate 76 drives the fork plate 81 to move up and down reciprocally, and the fork plate 81 drives the roller 84 to move up and down reciprocally. At the same time, the base plate 2 supports the L-shaped frame 82, and the L-shaped frame 82 supports the semi-circular 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-circular block 83, so that the semi-circular block 83 limits the roller 84. The friction of the roller 84 reduces the vibration generated when the ring plate 71 moves up and down, and prevents the equipment from vibrating violently during operation. This avoids the problem of poor machining accuracy caused by violent vibration of the equipment when the turning equipment is cutting the curved surface of the workpiece.

[0042] While the rectangular plate 76 drives the fork plate 81 to move up and down reciprocally, the fork plate 81 drives the ring frame 85 to move up and down reciprocally, the ring frame 85 drives the cylinder 86 to move up and down reciprocally, the cylinder 86 drives the spring 87 to move up and down reciprocally, the cylinder 86 drives the short rod 88 to move up and down reciprocally, the short rod 88 drives the arc baffle 89 to move up and down reciprocally, and the arc baffle 89 drives the arc-shaped rubber block 810 to move up and down reciprocally. During the up and down reciprocating movement of the arc-shaped rubber block 810, the arc-shaped rubber block 810 contacts the forward-rotating tubular workpiece, and under the action of extrusion force... The short rod 88 slides to the right in the cylinder 86, and the spring 87 of the cylinder 86 begins to contract. Under the elastic force of the spring 87, the arc-shaped rubber block 810 is pressed tightly against the rotating tubular workpiece. When the cutting head of the cutting module 14 cuts the curved surface of the tubular workpiece, the arc-shaped rubber block 810 presses against one side of the rotating tubular workpiece to prevent uneven force on the curved surface of the tubular workpiece when the equipment cuts the curved surface of the tubular workpiece. This avoids 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.
