Description

This invention relates to the building materials industry, in particular to the production of slabs from natural stone.

The purpose of the invention is to increase productivity and improve the quality of cladding plates.

FIG. 1 shows a structural diagram of the machine; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2, figure 4 - section bb In figure 1.

The machine contains a frame 1 and a rack 2 on which tool spindle heads 3 with electric motors 4 and a V-belt transmission 5 are placed. On the spindle heads 3 - the positions I, II, III, IV (Fig.2) are respectively installed sawing disk 6, grinding wheel 7, fine grinding wheel 8 and polishing pad 9.

A hard stop 10 is placed on the stand 2. The spindle heads 3 at positions I and II are equipped with a subsetting mechanism 11 containing a screw 12 and a nut 13. The adjusting mechanism 11 makes it possible to adjust the position of the tool relative to the fixed stop 10, and therefore the thickness of the cut tiles at position I and grinding depth at position (I.

The spindle heads 3 at positions III and IV are equipped with a mechanism 14 for longitudinal movement and pressing of a tool, comprising a spring 15, a nut 16, a spring adjusting force, a rod 17 and a screw probe 18,

ABOUT

s

In the rack 2 there is a hollow screw 19 on which the leash body 20 of the planetary gearbox 21 and the rotor 22 with spindle heads 23 carrying the blank blocks 24 and the mechanisms 25 for feeding and fastening the blanks are rigidly mounted.

The feed drive is carried out from the electric motor 26 through the V-belt transmission 27. the gearbox 28 and the coupling 29 to the drive shaft 30 of the planetary gearbox 27, the gearbox 21,

The drive shaft 30 is transmitted to the rotation of the spindle heads 23 through the central gear wheel 31 and gears 32 and transmitted to the rotation of the rotor 22 through the central gear 33 m gear unit 34 and 35 (satellites) rolling around the stationary gear 36, thereby rotating the body - lead 20, and hence the hollow shaft 19 with the rotor 22,

On the planetary gear 21, a copier 37 is installed, which interacts with the screw probe of the longitudinal movement mechanism and tool pressing.

The machining process is carried out continuously with continuously rotating tool spindle heads 3, rotor 22 and spindle heads 23 for blanks as follows,

At the position of the disk saw 6, the tile is cut from the blank block 24, when the spindle head 23 approaches the rigid stop, the workpiece 24 is unfolded and fed to the hard stop by the feed and spotting mechanism 25 of the workpiece and re-clamped (the mechanism is shown partially).

At position II, the end face of the workpiece 24 is ground with a predetermined grinding depth.

At the position IH, the end face of the workpiece 24 is finely polished with a given pressure determined by the spring setting.

The grinding head 3 operates in a galloping mode upon a command from the copier 37 through the mechanism for longitudinal movement and pressing of the tool.

At position IV, the face of the workpiece 24 is polished with a given pressure,

determined by the spring setting. The polishing head 3 also works in a jumping mode.

At position I, the finished tile is cut again and the processing cycle is repeated.

Making the feed mechanism in the form of a rotor carrying a spindle with preformed bars, which rotate simultaneously with the rotor from the planetary gearbox, ensures continuous operation of the cutting, grinding and polishing mechanisms, thereby increasing labor productivity.

Due to the achievement of the oscillating stage of the workpiece face relative to the grinder, the quality of the manufacturing of thin facing plits is improved.
