Description

(54) STONE TREATMENT DEVICE

one

The invention relates to the processing of flat products such as slabs, such as marble, granite and others, and can be used in the building materials industry and other industries.

A device for grinding and polishing a stone is known, which contains a movable carriage with a spindle head and a tool, which is moved between its limiting Upsra, installed with the possibility of interaction with the microswitches of the carriage 1.

However, the known device is characterized by the impossibility of automatic processing of the flat surfaces of curved contour plates.

Known grinding and polishing device containing a movable carriage with a spindle head and a tool that is moved between the stops limiting its course, installed with the ability to interact with

microswitch carriage. The stops are movable in the form of a parallelogram, on one link of which there is a probe that moves the stop depending on the contour of the side surface of the unmounted f 2j plate.

This device is characterized by the impossibility of processing products of large width due to the fact that the course is structurally limited. Besides,

10, the device does not allow processing with a carriage mounted on an automatically reversible bridge, since the stop, made in the form of a parallelogram, provides only one way movement of the product relative to the bridge.

The purpose of the invention is to increase its hydrofoil by ensuring the operation of un-edged flat products with a curvilinear contour of large dimensions.

This goal is achieved by the fact that the device is equipped with a significant pair of movable stops of flexible elements and block systems with hydraulic cylinders, each of the stops being attached to a flexible element between two block systems. FIG. 1 schematically shows the device, a general view; in fig. 2 - hydraulic scheme; The device consists of a bridge 1 with an on: yuravlimi 2. On a bridge 1 on their guides a carriage 3 is fixed with plungers 4 and 5 with a spindle head 6 and a tool 7. On one side of the tool axis there are stops 8 and 9, on the other, Yu and 11. Article 12 is mounted on the table 13. The stop 8 (see. Fig. 2) is fixed to the track 14, enveloping the block systems 15 and Ifc), which are installed respectively on the hydraulic cylinder rods 17 and 18 Stop 9 - on cable 19 with block scotomas 20 and 21 and hydraulic cylinders 22 and 23. Stop 1O - on cable 24 with block system 25 and 26 and hydraulic cylinders 27 and 28. Stop 11 - on cable 29 with block systems 30 and 31 and hydraulic cylinders 32 and 33. Hydraulic cylinders 17, 23, 27, 33 are connected to the Maracipan pressure head through one of the taps of the distributor 34 , through the other -j, the hydraulic cylinders 18, 22, 28, 32 are connected. The same pressure line is connected through the distributor 35 of the plunger 4 and 5, and the hydraulic motor of the bridge 37 through the distributor 36. On the carriage 3 there are installed microswitches 38 and 39 interacting with movement carriages 3 with movable stops 8 and 9, and on bridge 1 - microswitches 4О and 41, interacting e with movable stops 8 and 9 when moving bridge 1 for the dimensions of the product in one direction, and microswitches 42 and 43 that are in contact with movable stops 1O and 11 when moving bridge 1 for the dimensions of the product in the other direction. The operation of the proposed device is as follows. When the grinding tool 7 is lowered onto the product 12, the valve 34 and 35 is turned on, the carriage 3 is moved by means of the plungers 4 and 5, the hydraulic cylinder rods 18, 22, 28, 32 are pushed out, and the hydraulic cylinder rods 17 are pushed out , 23, 27, 33 w. As a result, the stops 8-11 move to the workpiece and rest against its Tqpubi. During grinding, the microswitches 38 and 39 of the carriage, meeting with stops 8 and 9, give a signal through the time relay to move the bridge 1. One of the distributor 36 magnets is turned on — the hydraulic motor of the bridge 37 starts to rotate. When the bridge is moved in one direction, the stops 8 and 9 meet microswitches 4O and 41, while moving the bridge in the other direction beyond the dimensions of the product, stops 10 and 11 meet microswitches 42 and 43. In either case, a signal is issued to reverse the bridge 1. Thus, microswitches 38 and 39 control L1FUYUT product width 12, and microswitches 40 - 43 - its length. The proposed grinding and polishing device for stone processing allows an increase in productivity by providing treatment of products of wide width and different lengths with a carriage with a tool mounted on an automatically reversible bridge. Claims A stone processing device comprising a movable carriage with a spindle head mounted on a bridge between limiting movable stops and microswitches, characterized in that, in order to increase productivity by treating non-edged products of large a width, the device is provided with an additional pair of stops, flexible linkage and block systems with hydraulic cylinders, with the stops fixed on the flexible link-between block systems.
