Description

Marble carving surface polishing all-in-one

Technical Field

The invention relates to the field of polishing equipment, in particular to a marble carving surface polishing all-in-one machine.

Background

Marble is a common stone material, and is used more and more widely in the decorative material industry.

All artificial marbles and many natural marbles have rough surfaces, and if the surface roughness is too low, the artificial marbles are easy to store dirt and are easy to damage surfaces when being collided, so that most marbles need to be polished in the end use process, and the artificial marbles are beautiful and extremely resistant to pollution.

Traditionally, marble polishing is almost performed in a mechanical mode, a grinding wheel rotates at a high speed to sweep a plane to be processed, and the surface roughness is reduced, however, the improvement of the surface roughness is limited in the polishing mode of the grinding wheel, the roughness of Ra0.8 is almost limited, the polishing mode cannot be assisted when higher precision is required, and a large amount of dust generated in the polishing process pollutes the surrounding environment.

Some polishing devices for eliminating dust pollution appear in the prior art, and no equipment for further improving polishing precision exists in a dust collection or water spraying mode.

Disclosure of Invention

The invention aims to provide a marble carving surface polishing all-in-one machine to solve the problems in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides a marble carving surface finish all-in-one, including inner tube, including a motor, an end cap, a controller, and a cover plate, stirring subassembly, polishing solution and base plate, the base plate passes through frame alignment and installs on marble carving treats polishing plane, surface mounting motor on the base plate, the base plate lower surface passes through connecting rod connection opening inner tube down, the stirring subassembly includes axle and stirring vane, stirring vane is located the inner tube, stirring vane is up through hub connection to motor, the inner tube includes barrel and sealed support piece, be full of polishing solution in the barrel, the position department that the barrel was passed to the axle sets up sealed support piece.

The invention uses polishing solution to polish, the polishing solution contains a certain content of polishing particles, the particles are remained in the polishing solution, the polishing solution is stirred by the stirring component and contacts with the plane to be polished, and burrs on the plane to be polished and protrusions on the surface roughness microscale are ground flat in the process that the particles continuously wash the plane to be polished, thereby achieving the purposes of reducing the roughness and improving the surface smoothness, the smaller the grain size of the grains in the polishing solution is selected, can continuously improve the smoothness of the surface to be polished, compared with the polished objects such as a mechanical grinding wheel and the like, the precision grade is not limited, different from chemical means such as acid-base corrosion, the polishing solution with the fine particles is still a pure physical means, so that the chemical properties of the surface of the marble cannot be damaged, and the problems of secondary chemical pollution and the like cannot be caused.

The power of stirring the polishing solution by the stirring blades comes from the motor above, the lower cantilever structure is provided with a sealing support piece for providing the rotation stability of the shaft, and meanwhile, in order to prevent the polishing solution from splashing out of the position where the shaft passes through the cylinder body and splashing into the bearing in the sealing support piece, the bearing is undoubtedly damaged by fine particles in the polishing solution, so the sealing support piece has the sealing function towards the polishing solution.

Further, the polishing all-in-one machine further comprises an outer barrel, the outer barrel is also provided with an opening facing downwards, the outer barrel is sleeved outside the inner barrel, the outer barrel comprises a plurality of splicing plates, the side faces of the splicing plates are provided with mortises, the splicing plates are embedded together through the mortises and can translate along the vertical direction independently, the lower ends of the splicing plates are provided with sealing strips, the sealing strips are attached to the polishing plane to be tightly treated, pre-tightening columns are upwards arranged on the splicing plates, and the upper ends of the pre-tightening columns are inserted into the substrate and abut against pre-tightening springs arranged in the substrate.

The purpose of the outer cylinder is to provide a working area with perfect sealing for the polishing liquid, a circle of ring bodies at the bottom of the outer cylinder is contacted with the surface of marble to form a plane to be polished, and a plurality of bulges may exist on the circle, if the circle at the bottom of the outer cylinder is a rigid or only a thin layer of rubber pad, the bulges can cause gaps, so that the polishing liquid in the cylinder flows out to influence the use. The outer barrel is divided into a plurality of splicing plates by a fan shape, the splicing plates are like side plates of a traditional wooden barrel, but the splicing plates are mutually embedded through mortises to form a ring shape, the splicing plates are mutually independent in the vertical direction, a bulge exists at a certain position, the splicing plates at the position can move upwards for a certain distance without influencing the surrounding splicing plates, all the splicing plates are downwards compressed by pre-tightening springs in the base plate, so that sealing strips at the bottom of the splicing plates are all attached to the surface of marble to form a ring-shaped sealing ring, and polishing liquid in the device is prevented from being leaked.

Further, stirring vane is a plurality of stirring boards that set up on a section body of rod, and stirring vane's size reduces along radial gradually. If the stirring blades uniformly stir the polishing solution to enable the polishing solution to concentrically rotate, namely the rotation angular velocity is approximately equal along the radial direction, the linear speed of the contact between the polishing solution positioned on the outer ring and the surface to be polished is greater than that of the contact between the polishing solution positioned on the outer ring and the surface to be polished, so that the problem of inconsistent polishing speed is caused, the polishing is carried out at the same time, the abrasion at the outer ring is large, and the abrasion at the inner ring is small and the polishing is not in place;

in order to avoid this, by providing agitating blades of different sizes, the agitating blade near the axis is larger, while the agitating blade far from the axis is smaller, and the large blade transmits more power to the water body than the small blade, so that although the agitating blades are concentric in rotation angular velocity, the power ratio of different blades transmitted to the polishing liquid is reduced in the radial direction, so that the polishing liquid has different angular velocities in the radial direction of the rotation axis thereof in the top view direction, two moving micelles located on different radii are examined, and their respective rotation radii are R1 and R2, the angular velocity of the micelle located on the outer side is w1, and the angular velocity located on the inner side is w2, and by adjusting the sizes of the respective agitating blades arranged in the radial direction, w 1R 1= w 2R 2, the contact line velocity of the polishing liquid on the whole polishing plane is made as identical as possible, and since the number of the agitating blades is necessarily limited, this way of balancing the line speed can only be made approximately uniform. In addition, because the fluid micro-clusters on different radiuses have different rotating speeds, disturbance exists on the speed boundary, and then the particles for polishing are uniformly distributed in the whole flow field range.

In addition, because the fluid micelles have different angular velocities for balancing the contact linear velocities at different radiuses, and because the polishing solution is not increased or decreased, namely, no speed singularity or material suction point/ejection point exists in the flow field, the internal friction and frictional heat are inevitably generated between the adjacent micelles, the temperature of the polishing solution is improved, the fluidity is greatly enhanced, and the polishing performance of the particles in the polishing solution is better.

Furthermore, a magnet is arranged in the shaft, the polishing solution contains fine powder particles, the fine powder particles have permanent magnetism, and the particle size of the fine powder particles is at least one order of magnitude lower than the target roughness of the polishing surface.

The polishing process is realized by the rotation process of the polishing liquid, although fine powder particles tend to be stirred by the liquid to be uniform, the particles also tend to gather towards an outer ring due to the action of centrifugal force, so that the centrifugal force is provided by using magnetism, the centrifugal force existing in the operation is balanced, and the particles can be freely dispersed to carry out the polishing process. The marble impacted by the particles on the polished plane is mixed into the polishing solution, the polished plane can be scratched after the marble falls off from the surface, and the marble is not attracted by the shaft, so the marble can be thrown to the outer ring after rotating in the polishing solution for a certain time, the average particle size of the falling marble particles is determined by the target roughness of the plane to be polished, and the marble particles and the fine powder particles for polishing have larger particle size difference to help quick separation so as to be tightly attached to the periphery.

Preferably, the bottom of the inner wall of the cylinder side is provided with an annular detention groove, the upper part of the detention groove inclines upwards, and the lower part of the detention groove is horizontal or concave towards the wall surface of the cylinder.

The stagnation grooves accommodate the marble particles falling from the plane to be processed in the aforementioned polishing process.

Further, the polishing all-in-one machine further comprises a liquid injection pipe, the inner barrel further comprises a liquid injection hole and a vent valve, the liquid injection hole is formed in the top surface of the barrel body, and the liquid injection pipe is connected with the liquid injection hole. The liquid injection pipe adds the polishing liquid into the device from the upper part of the inner barrel, namely the polishing liquid is added after all other components are installed in place. The air release valve can exhaust air in the cylinder in the process of adding the polishing liquid.

Further, the air release valve comprises a valve ball and a mounting plate, an air release hole is formed in the upper surface of the cylinder body, the air release hole is a counter bore with an inclined surface, a countersunk head is arranged below the counter bore, the mounting plate is in threaded connection with the bottom end of the air release hole, a plurality of through holes are formed in the surface of the mounting plate, and the valve ball is arranged between the mounting plate and the inclined surface of the air release hole. The air release valve is used for discharging air in the cylinder in the liquid injection process, but needs to be closed in time after the discharge is finished, a valve ball with the density smaller than that of the polishing liquid is used for the on-off component, an air channel is reserved when the air is reserved, and when the polishing liquid in the cylinder rises to the valve ball after being filled, the valve ball is lifted through the buoyancy support so as to seal the air exhaust channel.

Preferably, the pre-tightening spring is a clockwork spring. The elasticity of the spring does not change along with the action stroke, and after initialization, as long as the pre-tightening springs are in a compression state, all the pre-tightening columns are subjected to the same downward abutting force, so that a circle of the bottom of the outer cylinder in contact with the marble surface has the same sealing force.

Furthermore, the magnet in the shaft is an electromagnet, and the electromagnet is electrically connected with the outside. The electromagnet can change the magnetic force by electric signals so as to provide matched centripetal force for different rotating speeds of fine powder particles in the polishing solution.

Compared with the prior art, the invention has the beneficial effects that: the invention uses the particles below the micron level as the polishing agent, the particles are mixed in the liquid to form the polishing liquid, the polishing liquid is contacted with the plane to be polished after rotating at a high speed, and the microscopic protrusions on the marble plane are ground to achieve the polishing effect; when the stirring blades with gradually changed sizes rotate, different forces can be transmitted to the surrounding polishing solution, so that the polishing solution has different angular speeds, and the polishing solution has approximately equal rotating linear speeds by matching with the radius difference, so that the polishing solution uniformly contacts the surface of the marble for polishing, and the phenomenon that part of a matrix is lost due to excessive polishing and the luster is insufficient due to insufficient polishing at one position is not easy to occur; the angular velocity difference enables the polishing solution to generate heat when rotating, so that the fluidity is improved, and microscopic protrusions on a plane to be polished can be softened to a certain degree.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, a marble carving surface polishing all-in-one, including inner tube 1, motor 3, stirring subassembly 4, polishing solution 5 and base plate 7, base plate 7 passes through frame alignment and installs on the plane of treating polishing of marble carving, surface mounting motor 3 on the base plate 7, the inner tube 1 that the opening is down is connected through the connecting rod to the base plate 7 lower surface, stirring subassembly 4 includes axle 41 and stirring vane 42, stirring vane 42 is arranged in inner tube 1, stirring vane 42 is connected to motor 3 through axle 41 up, inner tube 1 includes barrel 11 and sealed support piece 12, be full of polishing solution 5 in the barrel 11, axle 41 passes the position department of barrel 11 and sets up sealed support piece 12.

The invention uses the polishing solution 5 to polish, the polishing solution 5 contains a certain content of polishing particles, the particles are remained in the polishing solution 5, the polishing solution 5 is stirred by the stirring component 4, the polishing solution 5 is contacted with the plane to be polished, and burrs on the plane to be polished and protrusions on the microscopic scale of surface roughness are ground flat in the process that particles continuously wash the plane to be polished, thereby achieving the purposes of reducing the roughness and improving the surface smoothness, the smaller the grain size of the grains in the polishing solution 5 is selected, can continuously improve the smoothness of the surface to be polished, compared with the polished objects such as a mechanical grinding wheel and the like, the precision grade is not limited, different from chemical means such as acid-base corrosion, the polishing solution with the fine particles is still a pure physical means, so that the chemical properties of the surface of the marble cannot be damaged, and the problems of secondary chemical pollution and the like cannot be caused. It should be noted that the roughness cannot be increased across too many levels, for example, it is not convenient to polish a stone block with a surface roughness of 6.3 directly to 0.8 or even 0.4, and the roughness accuracy level should be increased by one level.

The stirring blade 42 stirs the polishing liquid 5 from the motor 3 above, the lower cantilever structure is provided with the seal support 12 for providing the rotational stability of the shaft 41, and the seal support 12 has a sealing function toward the polishing liquid 5 because the seal support 12 provides a radial support and fine particles in the polishing liquid 5 can damage the bearing in order to prevent the polishing liquid 5 from splashing out of the position where the shaft 41 passes through the cylinder 11 and into the bearing in the seal support 12.

As shown in fig. 1, 3 and 4, the polishing all-in-one machine further comprises an outer barrel 2, the outer barrel 2 is also provided with a downward opening, the outer barrel 2 is sleeved outside the inner barrel 1, the outer barrel 2 comprises a plurality of splicing plates 21, the side surfaces of the splicing plates 21 are provided with mortises 211, the splicing plates 21 are embedded together through the mortises 211 and can mutually independently translate along the vertical direction, the lower ends of the splicing plates 21 are provided with sealing strips 22, the sealing strips 22 are attached to the plane to be polished, the splicing plates 21 are upwards provided with pre-tightening columns 23, and the upper ends of the pre-tightening columns 23 are inserted into the substrate 7 and abut against pre-tightening springs 8 arranged.

The purpose of the outer cylinder 2 is to provide a working area with perfect sealing for the polishing liquid 5, a ring at the bottom of the outer cylinder 2 is contacted with the surface of marble to frame a plane to be polished, and a plurality of bulges may exist on the ring, if the ring at the bottom of the outer cylinder 2 is a rigid or only a thin layer of rubber pad, the bulges will cause gaps, so that the polishing liquid 5 in the cylinder 11 flows out to influence the use. The outer cylinder 2 is divided into a plurality of splicing plates 21 by sectors, which is the same as a side plate of a traditional wooden barrel, but the splicing plates 21 of the invention are mutually embedded through the mortise 211 to form a ring shape and are mutually independent in the vertical direction, as shown in fig. 3, a certain position is provided with a bulge, so that the splicing plates 21 at the position can move upwards for a certain distance without influencing the surrounding splicing plates 21, and all the splicing plates 21 are downwards compressed by pre-tightening springs in the substrate 7, so that sealing strips 22 at the bottoms of the splicing plates 21 are all attached to the surface of marble to form a ring-shaped sealing ring, and the leakage of polishing liquid 5 in the device is prevented.

As shown in fig. 6, the stirring blades 42 are a plurality of stirring plates disposed on a section of the rod body, and the size of the stirring blades 42 gradually decreases along the radial direction. If the stirring blades 42 uniformly stir the polishing solution 5 to make the polishing solution rotate concentrically, i.e. the rotation angular velocities are approximately equal in the radial direction, the linear velocity of the contact between the polishing solution 5 positioned on the outer ring and the surface to be polished is greater than that at the position of the inner ring, which causes the problem of inconsistent polishing velocity, and the polishing is performed at the same time, the abrasion at the outer ring is great, and the abrasion at the inner ring is small and the polishing is not in place;

in order to avoid this, by providing agitating blades 42 of different sizes, the agitating blade near the axis is larger, while the agitating blade far from the axis is smaller, and the larger blade transmits more power to the water body than the smaller blade, so that, although the agitating blades 42 are concentric in rotational angular velocity, the proportion of power transmitted to the polishing liquid 5 by the different blades is reduced in the radial direction, so that the polishing liquid 5 has different angular velocities in the radial direction of its rotational axis in the top view direction, as shown in fig. 7, two moving micelles located on different radii are examined, and their respective rotational radii are R1 and R2, the angular velocity of the outer micelle is w2, and the angular velocity of the inner micelle is w1, and the radial arrangement of the respective agitating blades 42 is adjusted in size so that w 1R 1= w 2R 2, thereby making the contact velocity with the polishing liquid 5 on the entire polishing plane as equal as possible, since the number of blades of the stirring blade 42 is necessarily a limited value, this manner of balancing the linear velocity can be achieved only approximately uniformly. In addition, because the fluid micro-clusters on different radiuses have different rotating speeds, disturbance exists on the speed boundary, and then the particles for polishing are uniformly distributed in the whole flow field range.

In addition, because the fluid micelles have different angular velocities in order to balance the contact linear velocities at different radiuses, and because the polishing solution 5 is not increased or decreased, that is, no speed singularity or material suction point/ejection point exists in the flow field, internal friction and frictional heat are inevitably generated between adjacent micelles, the temperature of the polishing solution 5 is increased, the fluidity is greatly enhanced, and the polishing performance of particles in the polishing solution 5 is better.

The shaft 41 is internally provided with a magnet, the polishing solution 5 contains fine powder particles, the fine powder particles have permanent magnetism, and the particle size of the fine powder particles is at least one order of magnitude lower than the target roughness of the polishing surface.

The polishing process is realized by the rotation process of the polishing liquid 5, although fine powder particles tend to be stirred by the liquid to be uniform, the particles tend to gather towards an outer ring due to the action of centrifugal force, so that the centrifugal force is provided by using magnetism, the centrifugal force existing in the operation is balanced, and the particles can be freely dispersed to carry out the polishing process. The marble impacted by the particles on the plane to be polished is mixed into the polishing solution 5, the plane to be polished can be scratched after falling from the surface, the marble is not attracted by the shaft 41, the marble can be thrown to an outer ring after rotating the polishing solution 5 for a certain time, the average particle size of the falling marble particles is determined by the target roughness of the plane to be polished, and the marble particles and fine powder particles for polishing have larger particle size difference to help quick separation so as to be tightly attached to the periphery.

As shown in fig. 1, an annular retention groove 112 is provided in the bottom of the inner wall of the cylindrical body 11, the upper part of the retention groove 112 is inclined upward, and the lower part of the retention groove 112 is horizontal or concave toward the wall surface of the cylindrical body 11.

The stagnation grooves 112 accommodate the marble particles falling from the plane to be processed by the aforementioned polishing process.

As shown in figure 1, the polishing all-in-one machine further comprises a liquid injection pipe 6, the inner barrel 1 further comprises a liquid injection hole 13 and a vent valve 14 which are arranged on the top surface of the barrel body 11, and the liquid injection hole 13 is connected with the liquid injection pipe 6. The liquid injection pipe 6 adds the polishing liquid 5 into the device from the upper part of the inner cylinder 1, namely, the polishing liquid 5 is added after all other parts are installed in place. The air release valve 14 can release air in the barrel 11 during the process of adding the polishing solution 5.

As shown in fig. 2, the purge valve 14 includes a valve ball 141 and a mounting plate 142, the upper surface of the cylinder 11 is provided with a purge hole 111, the purge hole 111 is a counter bore with an inclined surface and is countersunk, the mounting plate 142 is in threaded connection with the bottom end of the purge hole 111, the surface of the mounting plate 142 is provided with a plurality of through holes, and the valve ball 141 is disposed between the mounting plate 142 and the inclined surface of the purge hole 111. The air release valve 14 is used for discharging air in the barrel 11 during the liquid injection process, but needs to be closed in time after the discharge is finished, a valve ball 141 with density smaller than that of the polishing liquid 5 is used for the on-off component, as shown in fig. 2, an air passage is reserved when air still exists, and when the polishing liquid 5 in the barrel 11 is filled up and rises to the valve ball 141, the valve ball 141 is lifted up through buoyancy so as to close the air release passage.

As shown in fig. 5, the pre-tensioned spring 8 is a clockwork spring. The elasticity of the spring does not change with the action stroke, and after initialization, as long as the pre-tightening springs 8 are in a compressed state, all the pre-tightening columns 23 are subjected to the same downward abutting force, so that the bottom of the outer cylinder 2 and a circle of marble surface contact have the same sealing force.

The magnet in the shaft 41 is an electromagnet, and the electromagnet is electrically connected to the outside. The electromagnet can change the magnitude of the magnetic force by an electric signal to provide a matching centripetal force for different rotational speeds of the fine powder particles in the polishing liquid 5.

The main using process of the invention is as follows: arrange the device in the marble treat the polishing plane on, make level and install the back, through annotating liquid pipe 6 and pour into polishing solution 5 into in inner tube 1, then starter motor 3 drives stirring vane 42 rotatory, is located barrel 11, presses close to the rotary motion that treats 5 one-tenth constant linear velocities of polishing solution on polishing plane, polishes the surface uniformly, because 5 rotation angular velocity of polishing solution are different, and liquid friction leads to 5 temperature rises of polishing solution, and mobility is better, and the polishing surface is treated in warm and humid.
