The present invention relates to a stone polishing machine for polishing primary processed slabs, and in particular, it can be polished on both sides of the bogie by grinding wheels and triangular bogies mounted on both sides of the triangular prism, thus providing high precision and polishing efficiency. It is about a stone grinder that can be used.

As shown in FIG. 8, the conventional stone grinder is continuously installed from the rough grinding to the fine grinding as the wheel 103 is vertically installed on the conveyor belt 101 and the plate 103 placed on the conveyor belt proceeds. Has a configuration that is made up of.

The conventional stone grinding machine having such a configuration is capable of continuous work according to the progress of the conveyor belt, but exhibits very high work efficiency. However, the plate 103 is continuously transferred to the conveyor belt 101, and the belt feed roller As the bearing 104 bears the polishing pressure from the grinding wheel 102 in a simple supported state by the shaft 104, the shrinkage deformation of the rubber belt occurs due to the polishing pressure applied on the roller shaft 104, resulting in a considerably large processing error. By doing so, there is a problem of lowering the processing accuracy, and when the plate member is in contact with the roller shaft and the roller shaft, the polishing pressure is applied to the center of the plate, so that the sheet is easily broken when the plate is not sufficiently thick, thereby making it difficult to process the thin plate.

For this reason, the conventional stone grinder has a problem that it is impossible to mass-work, but it is impossible to process the thin plate material with precision processing required in high value-added plates.

In addition, since the traveling direction of the conveyor belt is always fixed and the grinding wheel can be transported only left and right up and down with respect to the traveling direction of the conveyor belt. No polishing pieces other than the zig-zag polishing pieces of the type were obtained.

In general, the zigzag grinding trajectory has traces of grinding wheels left on the polished surface. Therefore, in the case of a plate requiring beautiful gloss, it is necessary to finish it with a separate precision grinding machine. It can be called an inefficient polishing method.

The present invention solves the problems of the conventional stone polishing machine as described above, doubles the processing capacity in the same work space, and devised for the purpose of presenting a new stone polishing machine of the structure that can obtain a high working efficiency and high processing precision at the same time It is.

In order to achieve this, the stone grinding machine has a triangular structure, and the whetstone is mounted on both pillars, and the bottom of the pillar is a triangular bogie that is moved back and forth along the rail. The work efficiency is increased by being polished by the grinding wheel which is inclined along the road, and the stone is closely adhered to both sides of the triangular bogie so that even a thin plate can be processed without breaking, and the stone is transferred by the bogie. By adopting the method, it is possible to obtain a beautiful polished flagstone by various polishing tools.

When described in detail by the accompanying drawings as follows.

Figure 1 shows the front state of the present invention, Figure 2 shows a planar state of the present invention, the present invention is to show two pillars (1) It is arranged in the shape and each well is equipped with a known whetstone (2), the whetstone is connected to the hydraulic cylinder (3) having the upper portion of the column as a fixed point, the grinding wheel is the sliding surface of the column according to the piston movement of the hydraulic cylinder (1a) to be able to incline up and down movement, and at the bottom between the two pillars (1) to advance back and forth along the rail (4) It shows that it is the stone grinder which has the structure which arrange | positioned the trolley | bogie 5 of a mold.

The present invention by the above configuration is to increase the working efficiency through the efficient use of space by mounting the whetstone wheel on both sides of the column and to propose a corresponding bogie structure, and to enable precise polishing work, the conventional stone polishing structure It can be said that the flat bed structure for mounting the whetstone is inclined.

3a to 3c is a view showing a specific embodiment of the present invention, Figure 3c is a partial cross-sectional state diagram for showing the mounting state of the pillar and the wheel, 3b is a detailed view of the coupling portion of the column and the wheel 3c is an enlarged cross-sectional view of aa part of FIG. 3b.

As shown in each figure, the column 1 has a cross-sectional shape. In the center portion, the grinding wheel transfer groove 1b is formed in the center portion from the bottom to the upper portion, and the dovetail-type sliding surface 1a is formed at both pillar bottoms of the transfer groove, and the grinding wheel is mounted on the sliding surface. The piston head 3a of the hydraulic cylinder 3 having the columnar portion as a fixed point is connected to the whetstone, and the incline reciprocating motion is performed on the whetstone while the piston moves backward along the direction of the hydraulic pressure provided from the outside to the hydraulic cylinder. It is configured to grant.

The whetstone 2 is a whetstone undercarriage frame 2a that is coupled to the devtail type sliding surface 1a formed at the bottom of the column, and a whetstone that protrudes through the whetstone transfer groove formed on the column and protrudes into the columnar top surface. The whetstone driving motor 2d, the whetstone driving motor 2d mounted on the plate 2c of the whetstone upper frame, the whetstone lower frame and the upper frame, and the upper part of the whetstone driving motor through the belt 2c. A whetstone axle 2d connected to the shaft, a whetstone head 2f fixed to the whetstone axle by a spline 2d 'formed at the end of the whetstone axle and a set screw 2e, and a rack gear formed on one spline It is composed of a non-feeding device (2g) composed of a pinion gear (2g) provided laterally on the grindstone head so as to engage with '), and a grindstone (2h) attached to the grindstone head.

The pinion gear of the feed mechanism is rotated to adjust the protruding length of the whetstone head relative to the whetstone shaft by the above configuration, and according to the stroke of the piston of the hydraulic cylinder connecting one end of the top frame of the whetstone to the top of the column. The whetstone can be tilted up and down along the column surface to polish the slabs placed on the bogie.

A whetstone wheel having such a configuration is a well-known one used in a conventional stone polishing machine. The wagon wheel is mounted on both sides of a column arranged in a triangular shape to achieve an efficient installation space. The structure can be configured in various ways.

The trolley 5 is for mounting the slab 6, which is a workpiece, and the mounting surface of the slab is formed in a triangular shape having the same inclination angle as the sliding surface of each column, and the rail is moved by the feed force from the lead screw 5a. (4) It is configured to reciprocate the phase.

In this state, the plate 6 is mounted on both sides of the trolley by such a configuration, and is reciprocated in the front and rear direction along the rail by the operation of the lead screw, and the whetstone is tilted upward and downward on the column surface according to the stroke of the piston. The grindstone is rotated at high speed by the power from the motor in the state in which the polishing depth is adjusted by the unfeeding device to polish the plate.

Therefore, stone grinding is performed simultaneously by grinding wheels mounted on both pillars, which has one line and has twice the processing capacity, and maximizes space utilization, and the slope movement of grinding wheels and bogies. Combination of forward and backward movements can be used to obtain various polished quizzes.

FIG. 7 shows such polishing, and FIG. 7a shows the grinding of the square obtained by the order of the advance of the bogie-the bottom of the bogie-the back of the bogie-the top of the bogie with the whetstone wheel located at the upper edge of the stone. 7b is the same as the grinding wheel of the conventional grinding machine, and the 7c is the grinding wheel upward-the bogie forward-the boulder wheel downward-the bogie forward-the whetstone Secondary upwards-This can be obtained when the balance advances sequentially.

Figure 7d shows the quarry drawn by the bogie's advance-wagon wheel upward-bogie backward-whetstone upward-bogie forward-whetstone upward, and Fig. 7e shows the bogie forward and backward and when the wagon wheel up and down is repeatedly made. It is a quartet, and Fig. 7f becomes a quest to draw when performing the same motion as that of Fig. 7b.

In general, when the movement to draw a zigzag quarry like Figure 7b is used to increase the work efficiency even if the wear surface is somewhat poor, Figures 7e, 7f can be used to obtain a beautiful gloss.

As such, the present invention can easily obtain the grinding wheels, which are impossible in the conventional conveyor conveying method, by using a combination of whetstone wheels and bogies, thereby obtaining a beautiful glossy plate with high added value. It becomes possible.

In addition, even a thin plate is closely adhered to a trolley, unlike a conventional conveyor belt, so that the shrinkage error of the rubber belt can be eliminated without breaking during processing, thereby enabling precision machining.

The present invention is based on the above-described configuration, together with the configuration for allowing the finish polishing operation in the rough polishing operation to be carried out continuously on the same line.

That is, the present invention, as shown in Figure 4 by arranging the triangular pillars on the same line at regular intervals from the initial grinding by the coarse grindstone can be carried out continuously precision grinding by the grindstone with fine particles have.

This configuration allows the triangular bogie to perform coarse polishing during the first grinder and then to have a finer polished surface during the next grinder, and to achieve perfect gloss by allowing the particles to perform the final polishing by fine grindstones at the end of the line. It is to be able to obtain a plate having.

5 and 6 show a structure in which the stone polishing machine of the above-described configuration is superimposed on two lines in order to increase the installation efficiency of the polishing machine and to effectively utilize the space.

That is, one end of the pillar constituting the polishing machine is continuously arranged on two parallel lines so as to overlap each other, and a rectangular bogie conveying line is provided so as to pass through the bottom of each polisher, and each bogie conveying line has a lift chain (7). ), Several triangular bogies are connected to the lift chain and transported simultaneously.

In this configuration, the line transfer of the trolley by the lift chain is generally well known and is conveyed in a state where the trolley is simply placed on the lift chain, so that the mechanical precision is lower than that of the trolley by the rail, but the circular transfer is performed. It is possible to have mass production. Part A or part B in the drawing indicates a point at which the plate is mounted on the trolley or the discharged plate is discharged.

As described above, the basic idea of the present invention is A well-known whetstone wheel is mounted on both sides of the pillar to make the inclined movement along the column and to adjust the grinding depth of the whetstone.The triangle is designed to reciprocate along the rail on the lower part of the column and to mount slabs on both sides. It is equipped with a bogie to construct a stone polishing machine to double the stone processing capacity on the same line, and to precisely process thin stones in close contact with the bogie and the workpiece. Combination is to get a variety of polished to obtain a beautiful luster.

In addition, each embodiment is intended to demonstrate the possibility of continuous polishing work by arranging the independent stone polishing machine according to the present invention in a variety of ways to selectively described the various implementation methods of this paper, and does not exclude other implementation methods.
