Abstract

Disclosed is a grinding machine for granite plate material. A differential gear case is used to make the rotary speed of an inner and an outer shafts arranged inside a welding sleeve different so as to generate speed difference; driving members, such as an eccentric wheel, a cross axle, a slide block, a fork, etc., are used to make a grinding block follow a grinding head to rotate and meantime to oscillate; a touching processing surface is made into a straight line shape, and meantime, the grinding block is made of silicon carbide so as to make the grinding machine high grinding capacity. The utility model has the advantages of high productive efficiency, low cost, firm and durable structure and easy maintenance, and the products are flat and smooth.

Description

Granite board grinder

The utility model belongs to the abrasive machine field of processing building stones.

The grinding of present domestic building stones processing, its bistrique adopts the plane abrading block more.The granite slab material is hard and frangible, requires abrading block pressure very big when grinding on the one hand, and sharpening could insert and carry out grinding in the slabstone, but simultaneously, the bistrique gross pressure too greatly but can cause slabstone cracked.For solving this contradiction, often plane abrading block area is reduced, perhaps reduce the abrading block adhesion strength simultaneously, but this can make the abrading block quick abrasion, cause grinding machine production efficiency low, cost height, crudy are poor.In recent years, introduced some production efficiency height, good product quality, equipment and technology that competitiveness is strong from states such as Italy, West Germany, but needed the cost foreign exchange, with high costs, maintenance difficult, and introducing equipment is not a long-term plan.

It is smooth smooth that the purpose of this utility model is to make the granite in slab that a kind of grinding capacity is strong, production efficiency is high, grind, and processing cost is low, sturdy and durable, is convenient to the granite in slab grinder of operating maintenance.Facts have proved: grinder of the present utility model has reached this purpose fully, and this grinder is that road has been opened up in the technological transformation of the middle-size and small-size granite material of numerous domestic factory.

The utility model is achieved in that by differential case power of motor is passed on two concentric axles, make two concentric shafts that different rotating speeds be arranged, outer shaft drives the bistrique rotation, the rotation of an interior axle drive eccentric wheel, like this, between eccentric wheel and bistrique case, there is relative motion, pass through eccentric wheel, cross axle, driving member such as slide block and shift fork, make abrading block in along with the bistrique rotation, tangent to periphery direction along its rotation swings back and forth, and because the one side that contacts with building stones of abrading block is not plane but cylindrical cambered surface, make grinding change into line contact processing by plane contact processing, add the powerful big increase of point pressure in man-hour, production efficiency, product quality and yield rate all increase substantially; Also, processing cost is also greatly reduced because above-mentioned swing type abrading block has adopted carborundum to make raw material.

Further specify the utility model below in conjunction with accompanying drawing:

Fig. 1 is the schematic diagram of this granite in slab grinder bistrique and running part thereof.

Fig. 2 is the A-A profile.

This granite in slab grinder adopts bridge architecture, and two crossbeams of crane span structure can be walked on planar tracks, and being equipped with one on the crane span structure can have a circular guide pin bushing along the dolly of crane span structure track travel in the dolly, and bistrique can lifting in guide pin bushing.Bistrique and running part thereof are described below: motor 1 is given sleeve by differential gear housing 2 with transmission of power, wherein gear mesh 3 is given interior axle 5 with transmission of power, gear mesh 4 is given outer shaft 6 with transmission of power, because the speed ratio difference of two gear mesh has speed difference between axle 5 and the outer shaft 6 in making; Outer shaft 6 drives bistrique case 8 and rotates, and interior axle 5 drives eccentric wheel 7 friction tight with it and rotates; 7 of cross axle 10 and eccentric wheels are for being slidingly matched; Four slide blocks 9 are enclosed within four of cross axle 10 respectively and are outside the periphery of stem stem of crossing distribution, and stem stem can translations in the middle of slide block 9, and slide block 9 again can translation in the middle of the fork of shift fork 12; Two iron hoops 11 being close to 7 liang of wheel faces of eccentric wheel have limited cross axle 10 displacement in the axial direction; Shift fork 12 is connected with abrading block bracing frame 14 by mandrel 13; Vibration when grinding sheet material for reducing abrading block and machine operation vibration cause mutually shakes, and also has one deck Shockproof rubber 15 between abrading block 16 and bracing frame 14; For reducing the vibration that causes owing to the eccentric stiffener running, establish a stabilizer 17; For the axial displacement of restriction slide block, be provided with positive stop key 18; Have four abrading blocks 16 and attaching parts thereof on the bistrique.When carrying out the sheet material grinding, because interior outer shaft rotating speed difference, 7 pairs of bistrique casees 8 of eccentric wheel have relative motion, make the cross axle 10 can only translation in the plane at its place with respect to the bistrique case, each stem stem is by slide block 9, the center line that each shift fork 12 and abrading block 16 are produced with mandrel 13 is the rotation of axle, and it is the swing repeatedly of axle with mandrel 13 center lines that this motion has formed abrading block 16; This speed of swing repeatedly depends on inside and outside diaxon rotating speed extent.The utility model adopts oil bath lubrication to abrading block swing mechanism and gear-box, and complete machine transmission mechanism lubricating condition is good.

The embodiment technical specification:

Bistrique master motor: Y160L-4 15KW star triangle starting

Bistrique rotary grinding diameter: 500mm

Bistrique rotating speed: 330 rev/mins

Water consumption: 2.5m ³/ time

Can grind maximum sheet material specification: 2.4 * 1.5 meters

Grind sheet material glossiness 90-120 degree (stone matter difference is different)

Grind granite in slab output: 2～4m ²/ time (relevant) with the raw wool plate flatness

Bistrique walking dragging motor: 2 of YCT 132-4 1.5KW

125～1250 rev/mins of speed adjustable ranges

Fuselage: long * wide * high=4 * 4 * 1.8 meters

Complete machine weight: about 3.5 tons

Compare with hand steered grinding machine, gantry grinding machine with present embodiment, efficient can improve 10 times, compares with some numerical control bridge-type grinding machines on the market, and efficient is high 5 times, and it is good to grind the sheet material flatness, and thickness is even, and the sheet material percentage of damage is low.Owing to using silicon carbide grinding block, reduce by 80% than employing diamond grinding block consuming cost, and because of the whole planar linkage mechanisms that adopt of abrading block swing, it between the member face contact, equipment part processing is simpler, obtains degree of precision easily, long service life.
