Description

TECHNICAL FIELD

[0001] The present application relates to the polishing technical field, and in particular to a wood carving polishing device and an intelligent polishing method for wood carving artware in the later stage. BACKGROUND

[0002] Wood carving surface finishing usually needs to go through rough grinding, fine polishing, waxing and other independent processes. The existing polishing device mostly adopts a "single point rotation + manual feeding" mode, that is, the polishing wheel is directly driven by a motor, the workpiece is fixed on a stationary clamp, and the operator holds or uses a simple sliding table to make the wood carving repeatedly contact with the wheel surface, and then the clamp is loosened to manually turn over the wood carving. In this open structure, the pressing force between the wheel and the wood completely depends on the operator's experience, and the uneven cutting amount caused by pressure fluctuation easily causes local over-polishing, missed polishing or "bright spot" phenomenon; at the same time, the wheel speed is constant and has no linkage with the feeding action, and the polishing efficiency is limited by the manual moving speed, and the polishing degree has limited space for improvement.

[0003] In order to reduce the labor intensity, part of the equipment is additionally provided with a linear feeding mechanism, so that the polishing wheel can automatically reciprocate in a single direction. However, this reciprocating motion is only used to change the relative position of the wheel and the workpiece, and the polishing wheel itself still relies on an independent motor to rotate at a constant speed, and the power source is repeated and the structure is dispersed; and there is no speed ratio coupling between the feeding and the wheel speed, it is difficult to maintain a stable linear velocity difference in the process of changing the stroke, and the surface quality consistency is insufficient. In addition, the wax spraying system in the existing scheme is mostly controlled by intermittent foot pedal or electromagnetic valve, and the wax flow is not synchronized with the polishing action, which easily causes uneven wax layer thickness, secondary "dry polishing" and other problems; and once the clamp is fixed, it cannot automatically rotate and needs to be manually turned over, and the multi-faced wood carving must be clamped one by one, so the auxiliary time is long and it is difficult to realize continuous operation.

DETAILED DESCRIPTION

[0054] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application.

[0055] Please refer to Figures 1-10 As an embodiment of the present application, a wood carving polishing device comprises an operation table 1, a moving base 2 and a polishing wheel 3, the moving base 2 is arranged on the operation table 1 through a reciprocating mechanism, and the moving base 2 will move horizontally and reciprocally when the reciprocating mechanism operates.

[0056] The polishing wheel 3 is arranged on the moving base 2 through an elastic assembly, and the elastic assembly will make the polishing wheel 3 always adhere to the surface of the wood carving during the reciprocating movement of the moving base 2.

[0057] The operation table 1 is provided with a speed increasing mechanism, and the speed increasing mechanism is connected with the moving base 2 and the polishing wheel 3 respectively, and the speed increasing mechanism will drive the polishing wheel 3 to rotate rapidly during the reciprocating movement of the moving base 2.

[0058] Further comprising a clamp 4, a spray head 5 and an oil tank 6, the clamp 4 is rotatably arranged on the operation table 1 and can clamp and fix the wood carving, the spray head 5 is connected with the elastic assembly and located at the polishing wheel 3, and the operation table 1 is provided with a driving mechanism connected with the spray head 5 and the oil tank 6 respectively, and the driving mechanism can spray the wax oil in the oil tank 6 from the spray head 5 when the driving mechanism operates.

[0059] The driving mechanism is further connected with the clamp 4 and the reciprocating mechanism respectively, and the driving mechanism can drive the reciprocating mechanism to continuously operate and drive the clamp 4 to intermittently rotate when the driving mechanism operates.

[0060] In this embodiment, after the driving mechanism is started, power is simultaneously transmitted to the reciprocating mechanism and the oil pump; the reciprocating mechanism drives the moving base 2 to move horizontally and linearly on the operation table 1; the elastic assembly fixed with the moving base 2 moves reciprocally at the same time, and always presses the polishing wheel 3 to the surface of the wood carving by the elastic force of the elastic assembly, so as to keep adhering; during the reciprocating movement of the moving base 2, the speed increasing mechanism converts the linear motion into rotary motion, and drives the polishing wheel 3 to rotate at high speed after speed increasing, so that the polishing wheel 3 moves while cutting and polishing the wood carving; the oil pump driven by the driving mechanism pressurizes the wax oil in the oil tank 6 to the spray head 5, and the spray head 5 moves synchronously with the elastic assembly, so as to spray the wax oil in mist form to the contact area of the polishing wheel 3 and the wood carving, and realize polishing while waxing; the driving mechanism outputs a indexing action to the clamp 4 once after completing one or several reciprocating periods, so as to drive the clamp 4 to rotate the wood carving by a fixed angle, and make the next polishing surface enter the processing position; the above actions are cyclically performed until all the surfaces of the wood carving are polished.

[0061] As a further scheme of the present application, the elastic assembly comprises a sleeve 7 and a slide rod 8 in sliding fit with the sleeve 7, the sleeve 7 is vertically fixed on the moving seat 2, and the bottom of the slide rod 8 is rotationally provided with a rotating shaft 9, and the polishing wheel 3 is coaxially fixed on the rotating shaft 9.

[0062] The inside of the sleeve 7 is provided with a spring 10, and the two ends of the spring 10 are respectively abutted against the top of the slide rod 8 and the inner top of the sleeve 7.

[0063] In this embodiment, please refer to Figure 3 and Figure 6 , the sleeve 7 is vertically fixed on the moving seat 2, the slide rod 8 is inserted into the sleeve 7 and can slide up and down along the axis thereof, the spring 10 is arranged between the top end of the slide rod 8 and the inner top end of the sleeve 7, and the spring 10 is always in a compressed state to exert a downward pushing force on the slide rod 8.

[0064] The bottom end of the slide rod 8 is rotationally installed with the rotating shaft 9, and the polishing wheel 3 is coaxially fixed on the rotating shaft 9; when the moving seat 2 drives the whole assembly to approach the surface of the wood sculpture, the polishing wheel 3 first touches the wood sculpture, and the height variation of the surface of the wood sculpture forces the slide rod 8 to slide upward in the sleeve 7, further compressing the spring 10; the reaction force of the spring 10 is transmitted to the polishing wheel 3 through the slide rod 8 and the rotating shaft 9, so that the polishing wheel 3 is always tightly attached to the wood sculpture and keeps constant pressure.

[0065] During the reciprocating movement of the moving seat 2, the rotating shaft 9 drives the polishing wheel 3 to rotate under the driving of the external speed increasing mechanism, while the slide rod 8 slightly slides in the sleeve 7 along with the surface fluctuation, and the spring 10 adjusts the extension and contraction amount in real time to ensure the stable adhesion and pressure, thereby completing continuous polishing.

[0066] As a further scheme of the present application, the reciprocating mechanism comprises a reciprocating screw rod 11 and a first sprocket 12 coaxially fixed on one end of the reciprocating screw rod 11, and the reciprocating screw rod 11 is horizontally rotationally arranged on the operating table 1.

[0067] The moving seat 2 is in threaded fit with the reciprocating screw rod 11, and when the first sprocket 12 drives the reciprocating screw rod 11 to rotate and the moving seat 2 can only slide axially along the reciprocating screw rod 11 and cannot rotate, the moving seat 2 will move horizontally and reciprocally.

[0068] In this embodiment, please refer to Figure 7 and Figure 8 , the reciprocating screw rod 11 is horizontally arranged on the operating table 1 and can freely rotate about its axis; the moving seat 2 is screwed on the reciprocating screw rod 11 and is limited by the guide structure of the operating table 1, so that it can only slide axially along the reciprocating screw rod 11 and cannot rotate with the reciprocating screw rod 11.

[0069] When the first sprocket wheel 12 drives the reciprocating screw rod 11 to rotate under external drive, the screw pair converts the rotary motion into linear feeding of the moving base 2; since the reciprocating screw rod 11 is provided with left-right symmetrical closed spiral tracks on the surface, the sliding pin in the moving base 2 is alternately reversed in the tracks, so that the moving base 2 automatically changes the moving direction; with the continuous rotation of the reciprocating screw rod 11, the moving base 2 is continuously alternately reversed, and periodic horizontal reciprocating movement is formed on the operation table 1, thereby providing stable back-and-forth feeding action for the polishing wheel 3.

[0070] As a further scheme of the present application, the speed increasing mechanism comprises a rotating rod 13 and a sleeve ring 14, the rotating rod 13 is horizontally fixedly arranged on the operation table 1, and the sleeve ring 14 is rotationally arranged on the moving base 2 and coaxially sleeved on the outer wall of the rotating rod 13;

[0071] The inner wall of the sleeve ring 14 is rollingly embedded with a steel ball 15, and the outer wall of the rotating rod 13 is provided with a spiral groove 1301 along the length direction, and the steel ball 15 is also rollingly embedded in the spiral groove 1301;

[0072] A transmission shaft 16 is vertically rotationally arranged on the sleeve 7, one-end and the other-end of the transmission shaft 16 are coaxially fixedly arranged with a first bevel gear 17 and a second bevel gear 18 respectively, and the sleeve ring 14 is coaxially fixedly arranged with a third bevel gear 19 which is in mesh with the first bevel gear 17;

[0073] A linkage shaft 20 is horizontally rotationally arranged on the sleeve 7, and the linkage shaft 20 is coaxially fixedly arranged with a fourth bevel gear 21 which is in mesh with the second bevel gear 18;

[0074] The speed increasing mechanism further comprises a pin shaft 22, a first connecting rod 23 and a second connecting rod 24, one-end of the first connecting rod 23 and the second connecting rod 24 are rotationally connected with the pin shaft 22, the other-end of the first connecting rod 23 is rotationally connected with the linkage shaft 20, and the other-end of the second connecting rod 24 is rotationally connected with the rotating shaft 9;

[0075] A first belt pulley 25 is fixedly arranged on the linkage shaft 20, a second belt pulley 26 is fixedly arranged on the pin shaft 22, and the first belt pulley 25 and the second belt pulley 26 are connected through a first toothed belt 27;

[0076] A third belt pulley 28 is fixedly arranged on the pin shaft 22, and a fourth belt pulley 29 is fixedly arranged on the rotating shaft 9, and the third belt pulley 28 and the fourth belt pulley 29 are connected through a second toothed belt 30.

[0077] In this embodiment, please refer to Figure 3 , Figure 4 and Figure 6When the moving seat 2 axially slides along the rotating rod 13, the sleeve ring 14 is synchronously moved by the moving seat 2; the steel ball 15 in the sleeve ring 14 is embedded in the spiral groove 1301 on the outer wall of the rotating rod 13 at the same time, and the linear motion of the sleeve ring 14 forces the steel ball 15 to roll along the spiral groove 1301, thereby driving the sleeve ring 14 to rotate at high speed around its axis;

[0078] The No. 3 bevel gear 19 on the sleeve ring 14 rotates at the same time, meshes with the No. 1 bevel gear 17, changes the rotation in the horizontal plane into the rotation in the vertical plane and transmits to the transmission shaft 16; the No. 2 bevel gear 18 on the other end of the transmission shaft 16 meshes with the No. 4 bevel gear 21, changes the rotation again into the horizontal direction and transmits to the linkage shaft 20;

[0079] The No. 1 pulley 25 on the linkage shaft 20 drives the No. 2 pulley 26 on the pin shaft 22 through the first toothed belt 27, so that the pin shaft 22 obtains the rotation in the same direction as the linkage shaft 20; the No. 3 pulley 28 on the pin shaft 22 drives the No. 4 pulley 29 on the rotating shaft 9 through the second toothed belt 30, so that the rotating shaft 9 and the polishing wheel 3 fixed coaxially obtain higher rotating speed;

[0080] Since the first connecting rod 23 is hinged at the two ends with the linkage shaft 20 and the pin shaft 22 respectively, and the second connecting rod 24 is hinged at the two ends with the pin shaft 22 and the rotating shaft 9 respectively, the first connecting rod 23 and the second connecting rod 24 keep the constant center distance of the pulleys while transmitting the torque, so as to ensure that the toothed belt is always tensioned; due to the cooperation among the pin shaft 22, the first connecting rod 23 and the second connecting rod 24, the slide rod 8 can still transmit power when it is slightly up and down, so that each linear reciprocation of the moving seat 2 is gradually enlarged into the rapid rotation of the polishing wheel 3, and the high-speed polishing is realized while moving.

[0081] As a further scheme of the application, the driving mechanism comprises a pump machine 31, a conduit 32 and a hose 33, and the pump machine 31 is fixedly arranged on the operation table 1;

[0082] The liquid inlet of the pump machine 31 is communicated with the oil tank 6 through the conduit 32, and the liquid outlet of the pump machine 31 is communicated with the spray head 5 through the hose 33;

[0083] The driving disc 34 and the driven disc 35 are rotatably arranged on the operation table 1 respectively, and the driving disc 34 and the driven disc 35 are cooperated with each other, so that the driven disc 35 will be intermittently rotated by a preset angle when the driving disc 34 rotates;

[0084] The driven disc 35 is coaxially fixedly connected with the clamp 4, a mandrel 36 is rotatably arranged on the operation table 1, and one end of the mandrel 36 is coaxially fixedly connected with the output end of the pump machine 31;

[0085] The core shaft 36 is coaxially fixed with a No. 5 pulley 37, the driving disc 34 is coaxially fixed with a No. 6 pulley 38, and the No. 5 pulley 37 and the No. 6 pulley 38 are connected through a third toothed belt 39.

[0086] The core shaft 36 is coaxially fixed with a No. 2 sprocket 40, and the No. 2 sprocket 40 and the No. 1 sprocket 12 are connected through a chain 41.

[0087] In this embodiment, referring to Figure 6 、 Figure 8 and Figure 10 , when the pump 31 is started, the output end drives the core shaft 36 to rotate synchronously, the No. 5 pulley 37 on the core shaft 36 transmits the rotation to the No. 6 pulley 38 through the third toothed belt 39, so that the driving disc 34 rotates continuously.

[0088] The driving disc 34 and the driven disc 35 form a Malta mechanism, and the driving disc 34 rotates by one circle, the driven disc 35 is actuated once and rotates by a preset angle, the clamp 4 fixed coaxially with the driven disc 35 drives the wood carving to complete one indexing, so that the wood carving is turned over intermittently; at the same time, the No. 2 sprocket 40 on the core shaft 36 transmits the rotation to the No. 1 sprocket 12 through the chain 41, so that the reciprocating screw rod 11 rotates and drives the moving seat 2 to move horizontally and reciprocally.

[0089] During the rotation of the pump 31, the wax oil in the oil tank 6 is sucked into the pump cavity through the conduit 32, is sprayed out in a mist form through the hose 33, the nozzle 5 in sequence after being pressurized, and continuously supplies the wax to the polishing area along with the reciprocating movement of the moving seat 2; thus, the same pump 31 provides three action paths at the same time: one path is for intermittently actuating the clamp 4 through the pulleys, one path is for driving the reciprocating feed through the sprockets, and one path is for directly pumping the wax oil, so that the polishing, the turning over and the wax spraying are coordinately operated.

[0090] An intelligent polishing method for wood carving artware using the wood carving polishing equipment, comprising the following steps:

[0091] Step one: starting the pump, the core shaft rotates synchronously, the reciprocating screw rod is driven to rotate through the sprocket, the moving seat drives the polishing wheel to enter the initial working position, and the pump sucks the wax oil in the oil tank into the pump cavity through the conduit, and the nozzle is on standby;

[0092] Step two: the moving seat moves horizontally and reciprocally along the reciprocating screw rod, the sleeve ring rotates at a high speed due to the cooperation of the steel ball and the helical groove, the polishing wheel is driven to rotate rapidly through the bevel gear set, the pulley set and the connecting rod mechanism, the spring in the elastic assembly presses the sliding rod in real time, so that the polishing wheel always adheres to the surface of the wood carving, the first surface is polished at a high speed while moving, and the wax oil is sprayed in a mist form through the hose along with the nozzle synchronously, so that the wood carving is polished and waxed at the same time.

[0093] Step three: when the moving seat completes a reciprocating cycle, the mandrel rotates a circle through the pulley driven driving disc, the Malta mechanism moves the driven disc to drive the clamp to rotate intermittently by a preset angle, the next surface to be polished of the wood carving is automatically entered into the processing position, the reciprocating screw rod continues to operate, the moving seat immediately starts the next cycle polishing, and the cycle is repeated until all surfaces are processed;

[0094] Step four: after all surface polishing is completed, the pump machine stops, the mandrel stops rotating, the reciprocating movement, the wheel body rotation, the wax spraying and the clamp indexing are simultaneously terminated, the finished wood carving is taken down, and the intelligent polishing is completed.
