Description

Technical Field

[0001] The invention relates to the field of sculpture surface treatment equipment, in particular to a sculpture surface treatment device. Background Art

[0002] In the field of sculpture art, the treatment of sculpture surface is very important. Traditional sculpture surface treatment methods often rely on manual operation and have many limitations.

[0003] On the one hand, manual grinding and polishing of sculpture surfaces is not only inefficient, but also difficult to ensure the accuracy and consistency of the processing. Due to the subjectivity and instability of manual operation, different craftsmen may produce large differences in processing results. At the same time, manual processing is slow, and for large sculptures or mass-produced sculptures, it cannot meet the efficient production needs.

[0004] On the other hand, a large amount of dust is generated during the processing, which poses a serious threat to the working environment and the health of operators. The traditional treatment method lacks an effective dust collection and treatment mechanism, resulting in poor air quality in the workplace. Long-term exposure to such an environment may cause various respiratory diseases.

[0005] In addition, the traditional surface treatment angle of sculptures is relatively single, and it is difficult to achieve all-round treatment of sculptures. For some sculptures with complex shapes, it is difficult to grind and polish without dead angles by manual operation, and it is easy to have inadequate treatment, which affects the overall quality of the sculpture.

[0006] With the continuous advancement of science and technology, people have higher and higher requirements for the quality of sculpture art, and also put forward higher requirements for the efficiency, environmental protection and accuracy of the processing process.

[0015] Preferably, a rotating shaft is movably installed in the inner middle part of the workbench and the top end of the rotating shaft is fixedly installed in the middle part of the bottom end of the rotating disk, a worm gear is fixedly installed on the middle outer diameter of the rotating shaft, a third motor is fixedly installed on one side of the inner part of the workbench, a worm is fixedly installed on the driving end of the third motor, and the inner ends of the worm and the worm gear are meshingly connected.

[0016] Preferably, a contour camera is fixedly mounted on one side of the front end of the cylinder, and a control panel is fixedly mounted on the front end of the workbench.

[0017] Working principle: Place the sculpture to be processed on the three-jaw chuck, start the three-jaw chuck to clamp the bottom of the sculpture, and then use the contour camera at the front end of the cylinder to input the contour of the sculpture into the control panel. The third motor drives the worm to rotate, which drives the worm wheel and the shaft to rotate, thereby driving the sculpture on the three-jaw chuck to rotate. At the same time, the combined control of the X-axis motion module, the Y-axis motion module and the Z-axis motion module is used to drive the contour camera to input the complete shape of the sculpture into the control panel, which is convenient for subsequent precise surface treatment according to the shape data. When the sculpture needs to be surface polished, start the second motor, and drive the upper transmission rod to rotate through the second motor. When the transmission rod rotates, it will drive the transmission wheel on the outer diameter to rotate, and the transmission of the synchronous belt will drive the lower transmission wheel and the transmission The driving rod rotates. Since the magnetic coupler on the outer diameter of the upper transmission rod is blocked by the baffle but not on the lower side, the rear half of the upper transmission rod cannot rotate while the lower transmission rod can rotate normally. The rotating transmission rod on the lower side will drive the active bevel gear to rotate. The rotating active bevel gear meshes with the driven bevel gear to drive the short shaft and the grinding rod to rotate. The sculpture surface is polished by the high-speed rotating grinding rod. The movement of the grinding rod is controlled by the X-axis motion module, the Y-axis motion module and the Z-axis motion module to achieve all-round polishing of the sculpture. In addition, the extension and retraction of the internal piston rod can be controlled by the hydraulic rod to push or pull the movable block to move, thereby driving the cylinder and the grinding rod to rotate, adjusting the grinding angle of the grinding rod, and controlling the movement of the grinding rod by the third electric The motor drives the worm to rotate, which drives the worm wheel and the rotating shaft to rotate, thereby driving the sculpture on the three-jaw chuck to rotate, and through the coordinated extension and retraction of the six electric cylinders, the three-jaw chuck and the sculpture can be translated in the X, Y, and Z directions and slightly rotated around the X, Y, and Z axes, a total of six degrees of freedom, as well as the compound movement of these degrees of freedom, to control the sculpture to perform adaptive tilt movement according to the position of the grinding rod, to achieve all-round grinding of the sculpture, avoid grinding dead angles, and improve the grinding quality. When the sculpture surface needs to be polished, start the first motor, drive the pinion to rotate through the first motor, drive the internal gear to rotate, thereby driving the cylinder to rotate, turn the polishing wheel downward, start the second motor again, and the positions of the upper and lower transmission rods are interchanged, but the position of the baffle is The position has not changed, and the baffle will still block the inside of the upper magnetic coupler, so at this time, the transmission rod on the lower side still rotates while the transmission rod on the upper side cannot rotate, and then the driving bevel gear and the driven bevel gear are used to drive the polishing wheel to rotate at high speed, and the motion module controls the route of the polishing wheel and the rotation and angle change of the sculpture itself to achieve high-quality polishing of the sculpture. When grinding or polishing the sculpture, the rotating transmission rod will also drive the cam in the middle to do circular motion. The moving cam will continuously lift and lower the piston plate, and cooperate with the reset spring to make the piston plate continuously reciprocate up and down in the square tube. When the piston plate drops, the air pressure in the dust suction pipe decreases, and the external atmospheric pressure pushes open the rubber one-way valve in the intake pipe.The dust generated during grinding and polishing is sucked into the dust suction pipe through the air intake pipe. When the piston plate rises, the air pressure inside the dust suction pipe increases, closing the rubber one-way valve in the air intake pipe and opening the rubber one-way valve in the exhaust pipe. The dust in the dust suction pipe is discharged into the exhaust pipe and then discharged into the outside air after being filtered by the dust removal filter.

[0018] The present invention provides a sculpture surface treatment device having the following beneficial effects:

[0019] 1. The present invention uses the contour camera at the front end of the cylinder to input the contour shape of the sculpture into the control panel, and at the same time drives the contour camera to input the complete shape of the sculpture into the control panel through the combined control of the X-axis motion module, the Y-axis motion module and the Z-axis motion module, so as to facilitate the subsequent precise surface treatment according to the shape data, thereby greatly improving the accuracy and pertinence of the surface treatment.

[0020] 2. The present invention controls the extension and retraction of the internal piston rod through a hydraulic rod to push or pull the movable block to move, thereby driving the cylinder and the polishing rod to rotate, and drives the worm to rotate through a third motor to drive the worm wheel and the rotating shaft to rotate, thereby driving the sculpture on the three-jaw chuck to rotate, and realizes the translation of the three-jaw chuck and the sculpture in the X, Y, and Z directions and the slight rotation around the X, Y, and Z axes through the coordinated extension and retraction of six electric cylinders. A total of six degrees of freedom and the compound movement of these degrees of freedom are achieved, and the sculpture is controlled to perform adaptive tilt movement according to the position of the polishing rod, so as to achieve all-round polishing of the sculpture, avoid grinding dead angles, and improve the quality of grinding and polishing.

[0021] 3. The present invention starts the second motor, which can drive the upper and lower drive rods to rotate through the transmission wheel and the synchronous belt, thereby driving the grinding rod and the polishing wheel. The transmission efficiency is high, ensuring the efficient surface treatment. When the sculpture surface needs to be polished, the first motor is started to drive the pinion to rotate, which drives the inner gear to rotate, thereby driving the cylinder to rotate, and the polishing wheel is directed downward to quickly switch to the polishing mode. The operation is simple and convenient.

[0022] 4. When the sculpture is ground or polished, the rotating transmission rod of the present invention drives the cam in the middle to make a circular motion, so that the piston plate continuously makes a reciprocating up and down motion in the square tube. When the piston plate descends, the air pressure in the dust suction pipe decreases, and the external atmospheric pressure pushes open the rubber one-way valve in the air intake pipe. The dust generated during grinding and polishing is sucked into the dust suction pipe through the air intake pipe. When the piston plate rises, the internal air pressure of the dust suction pipe increases, closing the rubber one-way valve in the air intake pipe and pushing open the rubber one-way valve in the exhaust pipe. The dust in the dust suction pipe is discharged into the exhaust pipe and then discharged into the outside air after being filtered by the dust removal filter, thereby effectively reducing dust pollution and protecting the working environment and the health of operators.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.

[0034] Example:

[0035] Please see attached Figure 1 -Attached Fig. 9 , an embodiment of the present invention provides a sculpture surface treatment device, such as Figure 1 As shown, it includes a workbench 1, Y-axis motion modules 2 are fixedly installed on both sides of the top of the workbench 1, Z-axis motion modules 3 are fixedly installed on the driving end movable tables of the Y-axis motion module 2, and the inner driving end movable tables of the Z-axis motion module 3 are respectively fixedly installed on the two ends of the X-axis motion module 4. The mutual cooperation of the X-axis motion module 4, the Y-axis motion module 2 and the Z-axis motion module 3 can realize precise position control in three-dimensional space, providing a flexible moving basis for the subsequent surface treatment of the sculpture.

[0036] A fixed rod 5 is fixedly installed on the movable table at the driving end of the X-axis motion module 4, a movable rod 6 is movably installed at the end of the fixed rod 5, and a cylinder 7 is movably installed on the middle outer diameter of the movable rod 6. The fixed rod 5 provides support for the movable rod 6, and the combination of the movable rod 6 and the cylinder 7 provides a key structural foundation for subsequent grinding and polishing operations.

[0037] Transmission rods 8 are movably installed on the upper and lower sides of the cylinder 7, and short shafts 9 are movably installed on the front sides of the upper and lower ends of the cylinder 7. A grinding rod 10 is fixedly connected to the end of the lower short shaft 9, and a polishing wheel 11 is fixedly installed on the end of the upper short shaft 9. The transmission rod 8 can drive the short shaft 9 to rotate through a series of transmission structures, so that the grinding rod 10 and the polishing wheel 11 can play a role. When grinding operation is required, the grinding rod 10 on the lower side rotates at high speed to perform fine grinding on the sculpture surface; and when polishing operation is required, the polishing wheel 11 on the upper side can perform high-quality polishing on the sculpture surface, making the sculpture surface smoother and brighter.

[0038] In this embodiment, an outer ring groove 12 is provided on the outer side of one end of the cylinder 7 close to the fixed rod 5, and a sliding block 13 is movably installed inside the outer ring groove 12. A hydraulic rod 14 is movably installed on one side of the top end of the fixed rod 5, and the end of the hydraulic rod 14 is movably installed on one end of the sliding block 13. The hydraulic rod 14 can push or pull the sliding block 13 to move in the outer ring groove 12 of the cylinder 7 by controlling the extension and retraction of the internal piston rod. This design allows the cylinder 7 and the grinding rod 10 and polishing wheel 11 connected thereto to rotate, thereby adjusting the grinding angle of the grinding rod 10 to meet the surface treatment requirements of sculptures of different shapes.

[0039] Specifically, the hydraulic rod 14 controls the extension and retraction of the internal piston rod to push or pull the movable block to move, thereby driving the cylinder 7 and the polishing rod 10 to rotate, adjusting the polishing angle of the polishing rod 10, and the third motor 42 drives the worm 43 to rotate, driving the worm wheel 41 and the rotating shaft 40 to rotate, thereby driving the sculpture on the three-jaw chuck 39 to rotate, and the coordinated extension and retraction of the six electric cylinders 37 to achieve six degrees of freedom along the three-jaw chuck 39 and the sculpture in the X, Y, and Z directions and slight rotation around the X, Y, and Z axes, as well as the composite movement of these degrees of freedom, to control the sculpture to perform adaptive tilt movement according to the position of the polishing rod 10, to achieve all-round polishing of the sculpture, avoid polishing dead angles, and improve the polishing quality.

[0040] Furthermore, an inner ring groove 15 is opened on the inner side of one end of the cylinder 7 close to the fixed rod 5, and an inner gear 16 is fixedly installed on the inner wall of the inner ring groove 15. A first motor 17 is fixedly installed on the top of the movable rod 6 close to the fixed rod 5. A pinion 18 is fixedly installed on the driving end of the first motor 17 and the top of the pinion 18 is meshingly connected to the inner side of the inner gear 16. When the sculpture surface needs to be polished, the first motor 17 is started to drive the pinion 18 to rotate. The meshing transmission of the pinion 18 and the inner gear 16 drives the cylinder 7 to rotate, so that the direction of the polishing wheel 11 is downward, ready for the polishing operation. This design realizes the function of quickly switching to the polishing mode, and the operation is simple and convenient.

[0041] Specifically, when the sculpture surface needs to be polished, the first motor 17 is started, and the pinion 18 is driven to rotate by the first motor 17, which drives the internal gear 16 to rotate, thereby driving the cylinder 7 to rotate, and the polishing wheel 11 is turned downward. The second motor 23 is started again, and the positions of the upper and lower transmission rods 8 are interchanged, but the position of the baffle 22 does not change. The baffle 22 will still block the interior of the upper magnetic coupler 21, so at this time, the lower transmission rod 8 still rotates while the upper transmission rod 8 cannot rotate. The transmission of the active bevel gear 24 and the driven bevel gear 25 is then used to drive the polishing wheel 11 to rotate at a high speed, and the motion module cooperates to control the route of the polishing wheel 11 and the rotation and angle change of the sculpture itself to achieve high-quality polishing of the sculpture.

[0042] Furthermore, a transmission wheel 19 is fixedly installed on the outer diameter of the transmission rod 8 near the fixed rod 5, and the outer diameters of the transmission wheels 19 are connected by a synchronous belt 20. A magnetic coupler 21 is fixedly installed on the outer diameter of the transmission rod 8 near the transmission wheel 19. A baffle 22 is fixedly installed on one side of the top of the movable rod 6 located inside the cylinder 7, and the end of the baffle 22 extends to the inside of the upper magnetic coupler 21. A second motor 23 is fixedly installed on one end of the cylinder 7 near the fixed rod 5, and the driving end of the second motor 23 is fixedly connected to the transmission rod 8 on one side. At one end, after starting the second motor 23, the upper transmission rod 8 can be driven to rotate. When the transmission rod 8 rotates, the transmission wheel 19 on the outer diameter will be driven to rotate, and the transmission of the synchronous belt 20 will drive the lower transmission wheel 19 and the transmission rod 8 to rotate. Since the magnetic coupler 21 on the outer diameter of the upper transmission rod 8 is blocked by the baffle 22, the rear half of the upper transmission rod 8 cannot rotate, while the lower transmission rod 8 can rotate normally. This design ensures that the rotation of the grinding rod 10 or the polishing wheel 11 can be accurately controlled under different surface treatment requirements.

[0043] Furthermore, a driven bevel gear 25 is fixedly installed on the outer diameter of the transmission rod 8 on the side away from the fixed rod 5, and the inner end of the short shaft 9 extends to the interior of the cylinder 7 and is fixedly installed with a driven bevel gear 25. The inner ends of the driven bevel gears 25 and the active bevel gears 24 on the corresponding sides are meshed and connected. The rotating transmission rod 8 on the lower side will drive the active bevel gear 24 to rotate, and the meshing transmission of the active bevel gear 24 and the driven bevel gear 25 will drive the short shaft 9 and the grinding rod 10 or the polishing wheel 11 to rotate. This bevel gear transmission structure has high transmission efficiency and can ensure efficient surface treatment of the sculpture.

[0044] Specifically, when it is necessary to polish the surface of the sculpture, the second motor 23 is started, and the second motor 23 is used to drive the upper transmission rod 8 to rotate. When the transmission rod 8 rotates, the transmission wheel 19 on the outer diameter will be driven to rotate, and the transmission of the synchronous belt 20 will drive the lower transmission wheel 19 and the transmission rod 8 to rotate. Since the magnetic coupler 21 on the outer diameter of the upper transmission rod 8 is blocked by the baffle 22 while the lower one is not blocked, the rear half of the upper transmission rod 8 cannot rotate while the lower transmission rod 8 can rotate normally. The rotating transmission rod 8 on the lower side will drive the active bevel gear 24 to rotate, and the rotating active bevel gear 24 meshes with the driven bevel gear 25 for transmission, thereby driving the short shaft 9 and the polishing rod 10 to rotate, and the high-speed rotating polishing rod 10 is used to polish the surface of the sculpture, and the X-axis motion module 4, the Y-axis motion module 2 and the Z-axis motion module 3 are cooperated to control the movement of the polishing rod 10 to achieve all-round polishing of the sculpture.

[0045] Furthermore, a dust suction pipe 26 is fixedly installed at the end of the movable rod 6, a square tube 27 is fixedly installed on one side of the bottom end of the dust suction pipe 26, a piston plate 28 is movably installed inside the square tube 27, a return spring 29 is fixedly installed on one side of the top wall of the dust suction pipe 26 and the end of the return spring 29 is connected to the top of the piston plate 28, and a cam 30 is fixedly connected at a position corresponding to the piston plate 28 on the middle outer diameter of the transmission rod 8. When the sculpture is ground or polished, the rotating transmission rod 8 will drive the cam 30 in the middle to make a circular motion, and the moving cam 30 will continuously lift and lower the piston plate 28, and cooperate with the action of the return spring 29 to make the piston plate 28 continuously reciprocate up and down in the square tube 27.

[0046] Furthermore, the end of the dust suction pipe 26 extends to the outside of the cylinder 7 and an air inlet pipe 31 is fixedly installed on the lower side of the end, and an exhaust pipe 32 is fixedly installed on the upper side of the end of the dust suction pipe 26. The connection between the air inlet pipe 31 and the exhaust pipe 32 and the dust suction pipe 26 is fixedly installed with a rubber one-way valve 33, and the inner top of the exhaust pipe 32 is also fixedly installed with a dust removal filter 34. When the piston plate 28 descends, the air pressure in the dust suction pipe 26 decreases, and the external atmospheric pressure pushes the rubber one-way valve 33 in the air inlet pipe 31 up. The dust generated during grinding and polishing is sucked into the dust suction pipe 26 through the air inlet pipe 31. When the piston plate 28 rises, the air pressure inside the dust suction pipe 26 increases, closing the rubber one-way valve 33 in the air inlet pipe 31 and pushing open the rubber one-way valve 33 in the exhaust pipe 32. The dust in the dust suction pipe 26 is discharged into the exhaust pipe 32 and then filtered by the dust removal filter 34 before being discharged into the outside air. This design effectively reduces dust pollution and protects the working environment and the health of operators.

[0047] Specifically, when grinding or polishing the sculpture, the rotating transmission rod 8 will also drive the cam 30 in the middle to make a circular motion. The moving cam 30 will continuously lift and lower the piston plate 28, and cooperate with the action of the return spring 29 to make the piston plate 28 continuously reciprocate up and down in the square tube 27. When the piston plate 28 descends, the air pressure in the dust suction pipe 26 decreases, and the external atmospheric pressure pushes open the rubber one-way valve 33 in the intake pipe 31. The dust generated during grinding and polishing is sucked into the dust suction pipe 26 through the intake pipe 31. When the piston plate 28 rises, the internal air pressure of the dust suction pipe 26 increases, closing the rubber one-way valve 33 in the intake pipe 31 and pushing open the rubber one-way valve 33 in the exhaust pipe 32. The dust in the dust suction pipe 26 is discharged into the exhaust pipe 32, and then discharged into the outside air after being filtered by the dust removal filter 34.

[0048] A rotating disk 35 is movably installed in the middle of the top of the workbench 1 through a bearing seat, and three lower hinge supports 36 are fixedly installed on the upper surface of the rotating disk 35. Electric cylinders 37 are movably installed on both sides of the interior of the lower hinge supports 36, and the ends of the corresponding side electric cylinders 37 are movably arranged in the interior of the three upper hinge supports 38. The top ends of the upper hinge supports 38 are fixedly installed at the bottom ends of the three-jaw chuck 39. Through the coordinated extension and retraction of the six electric cylinders 37, a total of six degrees of freedom can be achieved along the three-jaw chuck 39 and the sculpture in the X, Y, and Z directions and slight rotation around the X, Y, and Z axes, as well as the compound movement of these degrees of freedom. This design can control the sculpture to perform adaptive tilt movement according to the position of the grinding rod 10 or the polishing wheel 11, thereby realizing all-round grinding and polishing of the sculpture, avoiding grinding dead angles, and improving the processing quality.

[0049] Furthermore, a rotating shaft 40 is movably installed in the inner middle part of the workbench 1 and the top end of the rotating shaft 40 is fixedly installed in the middle part of the bottom end of the rotating disk 35, a worm gear 41 is fixedly installed on the middle outer diameter of the rotating shaft 40, and a third motor 42 is fixedly installed on one side of the inner part of the workbench 1, a worm 43 is fixedly installed on the driving end of the third motor 42, and the worm 43 and the inner end of the worm gear 41 are meshed and connected, the third motor 42 drives the worm 43 to rotate, driving the worm gear 41 and the rotating shaft 40 to rotate, thereby driving the sculpture on the three-jaw chuck 39 to rotate, and this design, together with the cooperation of other motion modules and the electric cylinder 37, further improves the flexibility and comprehensiveness of the sculpture surface treatment.

[0050] Furthermore, a contour camera 44 is fixedly installed on one side of the front end of the cylinder 7, and a control panel 45 is fixedly installed on the front end of the workbench 1. The sculpture to be processed is placed on the three-jaw chuck 39, and the three-jaw chuck 39 is started to clamp the bottom of the sculpture, and then the contour camera 44 at the front end of the cylinder 7 is used to input the contour shape of the sculpture into the control panel 45. At the same time, the combined control of the X-axis motion module 4, the Y-axis motion module 2 and the Z-axis motion module 3 is used to drive the contour camera 44 to input the complete shape of the sculpture into the control panel 45, which facilitates the subsequent precise surface treatment according to the shape data, greatly improving the accuracy and pertinence of the surface treatment.

[0051] Specifically, the sculpture to be processed is placed on the three-jaw chuck 39, and the three-jaw chuck 39 is started to clamp and fix the bottom of the sculpture. Then, the contour camera 44 at the front end of the cylinder 7 is used to input the contour shape of the sculpture into the control panel 45. The third motor 42 drives the worm 43 to rotate, driving the worm wheel 41 and the rotating shaft 40 to rotate, thereby driving the sculpture on the three-jaw chuck 39 to rotate.
