Description

A marble carving surface polishing integrated machine

technical field

The invention relates to the field of polishing equipment, in particular to an integrated machine for polishing the surface of marble carvings.

Background technique

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

The surface of all artificial marble and many natural marbles is not smooth. If the surface roughness is too low, it is easy to hide dirt and surface damage when it is bumped. Therefore, most marbles need to be polished at the end of use. , beautiful and extremely resistant to contamination.

Traditionally, the polishing of marble is almost always carried out mechanically. The grinding wheel rotates at a high speed and sweeps the surface to be processed to reduce the surface roughness. However, the polishing method in the form of grinding wheel has a limited improvement in surface roughness, Ra0. The roughness of 8 is almost the limit, when there is a need for higher precision, there is nothing that can be done, and a large amount of dust generated during the polishing process pollutes the surrounding environment.

In the prior art, there are some polishing devices for eliminating dust pollution, and there is no device for further improving polishing accuracy by means of dust suction or water spraying.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a marble carving surface polishing integrated machine to solve the problems in the prior art.

To achieve the above object, the present invention provides the following technical solutions:

An integrated machine for polishing the surface of marble carvings, comprising an inner cylinder, a motor, a stirring component, a polishing liquid and a base plate, the base plate is aligned and installed on the surface to be polished of the marble carving through a frame, a motor is installed on the upper surface of the base plate, and the lower surface of the base plate is connected by connecting The rod is connected to the inner cylinder with the opening facing down. The stirring assembly includes a shaft and a stirring blade. The stirring blade is located in the inner cylinder. The stirring blade is connected to the motor through the shaft. The inner cylinder includes a cylinder body and a sealing support. A sealing support is provided at a position passing through the barrel.

In the present invention, polishing liquid is used for polishing. The polishing liquid contains a certain content of polishing particles, and the particles remain in the polishing liquid. As the stirring component stirs the polishing liquid, the polishing liquid contacts the plane to be polished, and the particles continuously wash the plane to be polished. In the polishing process, the burrs on the surface to be polished and the bumps on the microscopic scale of the surface roughness are smoothed, so as to reduce the roughness and improve the surface finish. The smaller the particle size of the particles in the polishing solution, the more Compared with polishing objects such as mechanical grinding wheels, the degree of smoothness of the surface is not limited in terms of accuracy level. Unlike chemical methods such as acid-base corrosion, polishing using polishing liquid with finely divided particles is still purely physical. It will damage the chemical properties of the marble surface, and will not cause problems such as secondary chemical pollution.

The power of the stirring blade to stir the polishing liquid comes from the motor above. In order to provide the rotation stability of the shaft, the lower cantilever structure is provided with a sealing support to provide radial support, and at the same time, to prevent the polishing liquid from splashing from the position where the shaft passes through the cylinder, and The bearing splashed into the sealing support, the fine particles in the polishing liquid will undoubtedly damage the bearing, so the sealing support also has the sealing function towards the polishing liquid.

Further, the all-in-one polishing machine also includes an outer cylinder, which also has an opening facing downward, the outer cylinder is sleeved outside the inner cylinder, and the outer cylinder includes a plurality of splicing plates, the sides of the splicing plates are provided with tongue grooves, and the plurality of splicing plates are embedded through the tongue and groove. They can be combined together and can be translated in the vertical direction independently of each other. The lower end of the splicing plate is provided with a sealing strip, and the sealing strip is close to the surface to be polished. The splicing plate is upwardly set with a pre-tightening column, and the upper end of the pre-tightening column is inserted into the base plate and abuts against the base plate. inner preload spring.

The purpose of setting the outer cylinder is to provide a working area with a perfect seal for the polishing liquid. A ring body at the bottom of the outer cylinder is in contact with the marble surface to frame the surface to be polished. On this ring, there may be several convexities. If the bottom ring of the outer cylinder is rigid or just a thin layer of rubber pad, then these protrusions will cause gaps, which will cause the polishing liquid in the cylinder to flow out and affect the use. The outer cylinder is fan-shaped and divided into several splicing panels, just like the side panels of traditional wooden barrels, but the splicing panels of the present invention are fitted with each other to form a ring shape, and are independent of each other in the vertical direction. If there is a bulge at this position, the splicing plate at this position can retreat upward for a certain distance without affecting the surrounding splicing plates. All the splicing plates are pressed down by the preload springs in the base plate, so that the The sealing strips are all attached to the marble surface to form a ring-shaped sealing ring to prevent the leakage of the polishing liquid in the device.

Further, the stirring blades are several stirring plates arranged on a section of the rod body, and the size of the stirring blades gradually decreases along the radial direction. The mutual friction between the polishing liquid and the surface to be polished is used as the polishing process, and the relative velocity on the contact surface determines the polishing force. If they are approximately equal, then the contact linear velocity between the polishing liquid on the outer ring and the surface to be polished is greater than that on the inner ring, resulting in the problem of inconsistent polishing speeds. Polishing at the same time will cause large wear at the outer ring and greater wear at the inner ring. The wear is small and the polishing is not in place;

In order to avoid this situation, by setting stirring blades of different sizes, the stirring blades near the axis are larger, and the stirring blades far away from the axis are smaller, and the large blades transmit more power to the water body than the small blades. Therefore, although the stirring blades are The angular velocity of concentric rotation is the same, but the proportion of power transmitted by different blades to the polishing liquid decreases in the radial direction. Therefore, the polishing liquid has different angular velocities along the radial direction of its rotation axis in the top view direction. The moving micelles on the radius have their respective rotation radii R1 and R2, the angular velocity of the micelles located on the outer side is w1, and the angular velocity of the micelle located on the inner side is w2, through the size adjustment of the radial arrangement of the corresponding stirring blades, so that w1*R1=w2 *R2, make the contact linear velocity with the polishing liquid on the entire polishing plane as the same as possible. Since the number of blades of the stirring blade must be a limited value, this method of balancing the linear velocity can only be approximately uniform. In addition, due to the different rotational speeds of fluid micelles on different radii, there is a disturbance on the speed boundary, and the particles used for polishing are uniformly distributed in the entire flow field.

In addition, in order to balance the contact linear velocities at different radii, the fluid micelles have different angular velocities, and because the polishing liquid does not increase or decrease, that is, there are no velocity singularities, material suction points/ejection points in the flow field, so, There must be internal friction of the liquid between adjacent micelles, and the friction generates heat, increasing the temperature of the polishing liquid, greatly enhancing the fluidity, and the polishing performance of the particles in the polishing liquid is better.

Further, a magnet is arranged inside the shaft, the polishing liquid 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.

Polishing is achieved during the rotation of the polishing liquid. Although the fine powder particles will be agitated by the liquid and tend to be uniform, but due to the centrifugal force, the particles will also tend to collect in the outer ring. Therefore, a magnetic force is used to provide a centripetal force to balance the centrifugal effect existing in the operation. , allowing the particles to spread freely and carry out the polishing process. The marble hit by the particles on the polishing plane is mixed into the polishing liquid, and it may scratch the polished plane after falling from the surface, and the marble is not attracted by the shaft, so as long as it is rotated in the polishing liquid for a certain period of time, It will be thrown to the outer ring. The target roughness of the surface to be polished determines the average particle size of the falling marble particles. The large difference in particle size between the marble particles and the fine powder particles used for polishing can help to separate them quickly and make them Stick to the periphery.

As an optimization, the bottom of the inner wall of the cylinder side is provided with an annular retention groove, the upper part of the retention groove is inclined upward, and the lower part of the retention groove is horizontal or concave toward the cylinder wall.

The retention tank contains the marble particles that have fallen from the surface to be machined during the aforementioned polishing process.

Further, the all-in-one polishing machine further includes a liquid injection pipe, the inner cylinder further includes a liquid injection hole and a gas release valve arranged on the top surface of the cylinder body, and the liquid injection hole is connected to the liquid injection pipe. The liquid injection pipe adds polishing liquid into the device from the upper part of the inner cylinder, that is, the polishing liquid is added after all other components are installed in place. The air release valve can discharge the air in the cylinder during the process of adding polishing liquid.

Further, the air release valve includes a valve ball and an installation plate, a air release hole is arranged on the upper surface of the cylinder, the air release hole is a countersunk hole with a slope and the countersunk head is at the bottom, the installation plate is screwed with the bottom end of the air release hole, and the surface of the installation plate is provided with Several through holes, the valve ball is placed between the mounting plate and the inclined surface of the vent hole. The air release valve is used to discharge the air in the cylinder during the liquid injection process, but it needs to be closed in time after the discharge is completed. A valve ball with a density less than that of the polishing liquid is used to switch the parts, and an air channel is left when there is still air. When the polishing liquid in the cylinder is filled and rises to the valve ball, the valve ball is lifted by the buoyancy support to close the exhaust passage.

As an optimization, the preload spring is a clockwork spring. The elastic force of the mainspring does not change with the action stroke. After initialization, as long as the preload springs are in a compressed state, all the preload columns are subjected to the same downward pressing force, so that the bottom of the outer cylinder and the marble are in a compressed state. One ring in contact with each other has the same sealing force.

Further, the magnet in the shaft is an electromagnet, and the electromagnet is electrically connected to the outside. The electromagnet can change the size of the magnetic force through the electrical signal, so as to provide the matching centripetal force for the different rotational speeds of the fine powder particles in the polishing liquid.

Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention uses particles below the micron level as a polishing agent, which is mixed in a liquid to become a polishing liquid, and is in contact with the plane to be polished after high-speed rotation, and smoothes the marble plane. The micro-bulges can achieve polishing effect; when the stirring blade with changing blade size rotates, it can transmit different forces to the surrounding polishing liquid, so that it has different angular velocities, and with the difference in radius, the polishing liquid has approximately the same rotational linear speed , so as to uniformly contact the marble surface for polishing, and it is not easy to lose part of the matrix due to excessive polishing, and insufficient polishing to cause insufficient gloss; the difference in angular velocity makes the polishing liquid generate heat when it rotates, which not only improves fluidity, but also softens to a certain extent. Microscopic protrusions on the surface to be polished.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in Figure 1, an integrated machine for polishing the surface of marble carvings includes an inner cylinder 1, a motor 3, a stirring assembly 4, a polishing liquid 5 and a substrate 7. The substrate 7 is aligned and installed on the surface to be polished of the marble carving through a frame. , the motor 3 is installed on the upper surface of the base plate 7, the lower surface of the base plate 7 is connected to the inner cylinder 1 with the opening facing downward through the connecting rod, the stirring assembly 4 includes a shaft 41 and a stirring blade 42, the stirring blade 42 is located in the inner cylinder 1, and the stirring blade 42 faces upwards Connected to the motor 3 through the shaft 41 , the inner cylinder 1 includes a cylinder body 11 and a sealing support 12 .

In the present invention, polishing liquid 5 is used for polishing. The polishing liquid 5 contains a certain content of polishing particles, and the particles remain in the polishing liquid 5. With the stirring component 4 stirring the polishing liquid 5, the polishing liquid 5 is in contact with the surface to be polished, and the particles are continuously In the process of scouring the surface to be polished, the burrs on the surface to be polished and the protrusions on the microscopic scale of surface roughness are smoothed, so as to reduce the roughness and improve the surface finish. Small, it can continuously improve the smoothness of the surface to be polished. Compared with polishing objects such as mechanical grinding wheels, the accuracy level is not limited. Unlike chemical methods such as acid-base corrosion, polishing using polishing liquid with fine particles is still a problem. Pure physical means, first of all, will not damage the chemical properties of the marble surface, and will not cause secondary chemical pollution and other problems. It should be noted that the roughness cannot be improved across too many grades. For example, it is inconvenient to directly polish a stone with a surface roughness of 6.3 to 0.8 or even 0.4. The roughness accuracy grade should be improved step by step.

The power of the stirring blade 42 to stir the polishing liquid 5 comes from the motor 3 above. In order to provide the rotational stability of the shaft 41 in the lower cantilever structure, a sealing support 12 is provided to provide radial support, and at the same time, to prevent the polishing liquid 5 from passing through the barrel from the shaft 41 If the body 11 is splashed and splashed into the bearing in the sealing support 12 , the fine particles in the polishing liquid 5 will undoubtedly damage the bearing, so the sealing support 12 also has a sealing function towards the polishing liquid 5 .

As shown in Figures 1, 3, and 4, the integrated polishing machine further includes an outer cylinder 2, which also has an opening facing downward, the outer cylinder 2 is sleeved outside the inner cylinder 1, and the outer cylinder 2 includes a plurality of splicing plates 21. The splicing plates 21 There is a tongue and groove 211 on the side of the splicing plate 21, and several splicing plates 21 are fitted together through the tongue and groove 211 and can be translated in the vertical direction independently of each other. The lower end of the splicing plate 21 is provided with a sealing strip 22. The plate 21 is provided with a preload column 23 upward, and the upper end of the preload column 23 is inserted into the base plate 7 and abuts against the preload spring 8 in the base plate 7 .

The purpose of setting the outer cylinder 2 is to provide a working area with a perfect seal for the polishing liquid 5. A ring body at the bottom of the outer cylinder 2 is in contact with the marble surface and then frames the surface to be polished. There are several protrusions. If the bottom circle of the outer cylinder 2 is rigid or only a thin layer of rubber pads, these protrusions will cause gaps, and the polishing liquid 5 in the cylinder 11 will flow out and affect the use. The outer cylinder 2 is fan-shaped and divided into several splice plates 21, just like the side plates of a traditional wooden barrel, but the splice plates 21 of the present invention are fitted with each other through the tongue and groove 211 to form a ring, and are mutually in the vertical direction. Independent, as shown in FIG. 3, if there is a bulge at a certain position, then the splicing plate 21 at this position can retreat upward for a certain distance without affecting the surrounding splicing plates 21, and all the splicing plates 21 are covered by the substrate 7. The pre-tightening spring of the splicing plate 21 is pressed downward, so that the sealing strips 22 at the bottom of the splicing plate 21 are all attached to the marble surface, forming a ring-shaped sealing ring to prevent the leakage of the polishing liquid 5 in the device.

As shown in FIG. 6 , the stirring blades 42 are several stirring plates arranged on a section of the rod body, and the size of the stirring blades 42 gradually decreases in the radial direction. The mutual friction between the polishing liquid 5 and the surface to be polished is used as the polishing process, and the relative speed on the contact surface determines the polishing force. The radial direction is approximately equal, then the contact linear velocity between the polishing liquid 5 located on the outer ring and the surface to be polished is greater than that located on the inner ring, resulting in the problem of inconsistent polishing speeds. Polishing at the same time will cause large wear at the outer ring. , the wear at the inner ring is small, and the polishing is not in place;

In order to avoid this situation, by setting the stirring blades 42 of different sizes, the stirring blades near the axis are larger, and the stirring blades far away from the axis are smaller, and the large blades transmit more power to the water body than the small blades, so although the stirring blades 42 is the same concentric rotation angular velocity, but the ratio of the power transmitted by different blades to the polishing liquid 5 decreases in the radial direction, so the polishing liquid 5 has different angular velocities along the radial direction of its rotation axis in the top view direction, such as As shown in FIG. 7, two moving micelles with different radii are investigated, their respective radii of rotation are R1 and R2, the angular velocity of the micelles located on the outside is w2, and the angular velocity of the micelles located on the inside is w1, through the corresponding stirring blades 42 radial The size of the arrangement is adjusted so that w1*R1=w2*R2, so that the contact speed with the polishing liquid 5 on the entire polishing plane is as the same as possible. Since the number of blades of the stirring blade 42 must be a limited value, this method of balancing the linear speed only can be approximately uniform. In addition, due to the different rotation speeds of fluid micelles on different radii, there is a disturbance on the speed boundary, and the particles used for polishing are uniformly distributed in the entire flow field.

In addition, because the fluid micelles have different angular velocities in order to balance the contact linear velocities at different radii, and because the polishing liquid 5 does not increase or decrease, that is, there are no velocity singularities, material suction points/ejection points in the flow field, so , there must be internal friction of the liquid between adjacent micelles, friction generates heat, and the temperature of the polishing liquid 5 is increased, the fluidity is greatly enhanced, and the polishing performance of the particles in the polishing liquid 5 is better.

A magnet is arranged inside the shaft 41, the polishing liquid 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.

Polishing liquid 5 rotates to achieve polishing. Although the fine powder particles will be agitated by the liquid and tend to be uniform, but due to the effect of centrifugal force, there will also be a tendency for the particles to gather in the outer ring. Therefore, a magnetic force is used to provide a centripetal force to balance the centrifugal force existing in the operation. function, allowing the particles to spread freely and carry out the polishing process. The marble hit by the particles on the polishing plane is mixed into the polishing liquid 5, and it may scratch the polished plane after falling off the surface. The marble is not attracted by the shaft 41, so as long as it rotates in the polishing liquid 5 for a certain amount of time After time, it will be thrown to the outer ring. The target roughness of the surface to be polished determines the average particle size of the marble particles that fall down. The particle size of the marble particles and the fine powder particles used for polishing are greatly different, which can help rapid separation. , so that it is close to the periphery.

As shown in FIG. 1 , the bottom of the inner wall of the cylindrical body 11 is provided with an annular retention groove 112 .

The retention tank 112 contains marble particles that have fallen from the surface to be machined during the aforementioned polishing process.

The liquid injection pipe 6 adds the polishing liquid 5 into the device from the upper part of the inner cylinder 1, that is, the polishing liquid 5 is added after all other components are installed in place. The air release valve 14 can discharge the air in the cylinder 11 during the process of adding the polishing liquid 5 .

As shown in FIG. 2 , the air release valve 14 includes a valve ball 141 and a mounting plate 142. The upper surface of the cylinder body 11 is provided with a air release hole 111. The air release hole 111 is a countersunk hole with a slope and the countersunk head is at the bottom. The installation plate 142 is connected to the air release hole. The bottom end of 111 is threadedly connected, the surface of the mounting plate 142 is provided with a number of through holes, and the valve ball 141 is placed between the mounting plate 142 and the inclined surface of the vent hole 111 . The air release valve 14 is used to discharge the air in the cylinder 11 during the liquid injection process, but it needs to be closed in time after the discharge is completed, and a valve ball 141 with a density less than the polishing liquid 5 is used for the on-off parts, as shown in Figure 2, When there is still air left, an air passage is reserved. When the polishing liquid 5 in the cylinder 11 is filled and rises to the valve ball 141, the valve ball 141 is lifted by the buoyancy support to close the exhaust passage.

As shown in FIG. 5 , the preload spring 8 is a spring spring. The spring force of the spring does not change with the action stroke. After initialization, as long as the preload spring 8 is in a compressed state, all the preload columns 23 are subjected to the same downward pressing force, so that the outer cylinder 2 The bottom contact with the marble surface has 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 through an electrical signal, so as to provide a matching centripetal force for the different rotational speeds of the fine powder particles in the polishing liquid 5 .
