Abstract

The utility model relates to a stone-grinding machine, which is provided with a rotary table between a machine base walking frame and a machine frame of the stone-grinding machine. So the machine frame can revolve 360 DEG winding the machine base. The head of a stone-grinding machine can side-to-side control stick movement. The grinding end panel is enlarged. Meanwhile, the head of a stone-grinding machine can reverse end for end rapidity to grind, so the ground grinded is level and smooth. The head of a stone-grinding machine can also rotate the entire circle winding a transverse axis. The head of a stone-grinding machine can be fixed at any angles to grind. When a vibration damper is arranged, the vibration of a joystick is reduced. The head of a stone-grinding machine mainly uses the rotation of a curved surface triangular prism in a square socket to enable a triangle grinding wheel abrasion to grind a square trace. The head of a stone-grinding machine changed necessary components can still be used as an ordinary stone-grinding machine.

Description

Head of stone-grinding machine

The utility model relates to a kind of stone mill, belongs to building machinery.

Terrazzo floor attractive in appearancely, inexpensive is adopted by all kinds of buildings with it, the grinding of terrazzo floor all utilizes stone mill to finish, existing stone mill all has the labour-saving characteristics, but still come with some shortcomings: ground, grinding one place needs when grinding is carried out on ground on every side, whole of stone mill must be moved, cause the ground injustice that grinds like this, rough; Stone mill can not grinding ground corner in addition, has " dead angle ".

The purpose of this utility model is to provide a kind of stone mill of flexible operating, and not mobile stone mill support walker just can make the stone mill main body around 360 ° of support walker center steerings, and the stone mill head that provides simultaneously can carry out grinding to the ground corner.

The utility model is realized with following technical proposals: a kind of stone mill, comprise support walker, frame, be fixed in motor and control stick on the frame, be connected in the stone mill head on the motor shaft, support walker, frame link by rotary table, rotary table can be by being loaded on bearing block in the overcoat, being installed on the bearing inside and outside the bearing block and the main shaft that is supported in the bearing is formed, overcoat, main shaft are fixed on the frame, bearing block and support walker bearing connect firmly, frame can be installed damper around 360 ° of main shaft gyrations on control stick.This stone mill head can be comprise casing, transverse axis, be loaded on bevel gear on the transverse axis, with the passive bevel gear of bevel gear engagement, the affixed sliding cross coupling in vertical shaft lower end that connects firmly with passive bevel gear, there is a curved surface triangular prism half a coupler lower end under the sliding cross coupling, curved surface triangular prism bottom connects firmly bistrique, its center is over against curved surface triangular prism geometric center, the triangle emery wheel is installed on the bistrique, in the curved surface triangular prism side of the being sleeved on cover, side's cover is fixed on the casing inner wall, and curved surface triangular prism cross section inscribed triangle is an equilateral triangle.

The utility model stone mill adopts the turn-around machine holder structure, make frame turn round 360 ° around support walker (main shaft), the grinding stone head can swing, and has enlarged the grinding breadth when direction of advance work each time, simultaneously can also reverse end for end rapidly to carry out grinding, make the ground that grinds smooth, smooth.The grinding stone head also can rotate 360 ° around transverse axis, can be fixed on any angle and carry out grinding, and shock absorber can reduce to vibrate the adverse effect to the operator.Thereby the stone mill head utilizes the face triangular prism to rotate in side's cover and makes the track on the triangle wheel grinding ground that connects firmly with triangular prism is square, has solved the grinding " dead angle " of ground corner.It is long that the utility model also has efficient height, life-span, the characteristics of reliable operation.

Accompanying drawing has provided embodiment of the present utility model;

The utility model is described in further detail with reference to the accompanying drawings.

With reference to Fig. 1, Fig. 2, Fig. 3, motor 3 is housed on the frame 2, support walker 1 is made up of the road wheel 25 of in the support walker bearing 12 wheel shaft 24 being installed and be loaded on the wheel shaft 24, base 6 is by the bearing block 8 that is loaded in the overcoat 7, the main shafts 11 that are installed on inside and outside bearing 10 bearings 9 of bearing block 8 and are loaded in the bearing 10 are formed, bearing 10 usefulness axle sleeve and locking nuts, packing ring is fixed on the main shaft, main shaft 11 upper ends and frame 2 base plates are integrally welded, overcoat 7 is screwed on frame 2 base plates, support walker 1 bearing 12 is fixed on bearing block 8 bottoms, rotate control stick 4, frame 2 can be around main shaft 8 revolutions, control stick 4 is provided with shock absorber 26, and it is made up of force transmission shaft outer casing spring and yielding rubber cover, and its shell and frame 2 connect firmly, force transmission shaft and control stick 4 connect firmly, 5 of shock absorber 26 configurations, respectively 2 of control sticks about 4, middle horizontal 1, behind the stone mill vibration weakening, just not having strong vibration has reached the operator on hand on the control stick 4 like this.With reference to Fig. 4, stone mill head 5 is become by straight-bar machines and perpendicular mechanism, motor 3 output shafts 28 connect with transverse axis 14 through interior six side's coupling bands 29, casing 27 connects with straight-bar machines casing 30 by flange, the perpendicular machine casing 13 of stone mill head 5 has an annulus 31 by the transverse axis end, and straight-bar machines casing 30 left ends have a corresponding seam 32, two

casings

13,30 are coupled to each other by pressure ring 33 and bolt 34, when stone mill head 5 need be when transverse axis 14 rotations be arbitrarily angled, unclamp bolt 34, adjust head 5 angles, fastening bolt 34 gets final product.With reference to Fig. 5, Fig. 6, transverse axis 14 ends connect firmly bevel gear 15, through bevel gear 16 transmission vertical shafts 17, connect firmly sliding cross coupling 18 in vertical shaft 17 lower ends, it connects firmly equilateral curved surface triangular prism 20 on half a coupler 19 down, its cross section such as Fig. 6 show, triangular prism 20 overcoats one four directions cover 23, four directions cover 23 is fixed on casing 13 inwalls, triangular prism 20 and four directions cover 23 are by interior round nut 35 baffle plates 36 axial location, connect firmly bistrique 21 in triangular prism 20 lower ends equilateral triangle emery wheel 22 is installed on bistrique 21, bistrique 21 centers are over against triangular prism 20 geometric centers, connecing the equilateral triangle length of side in equilateral curved surface triangular prism 20 cross sections equates with the length of side of four directions cover 23, this stone mill head course of work is as follows: motor is through transverse axis 14,

bevel gear

15,16 drive vertical shaft 17 rotates, drive equilateral curved surface triangular prism 20 through sliding cross coupling 18 and in four directions cover 23, make eccentric rotary, three ribs of triangular prism 20 contact with the inwall of four directions cover 23 all the time, thereby make the track squarely of the bistrique equilateral triangle emery wheel 22 that connects firmly with triangular prism, so just, can carry out the corner grinding, eliminate " dead angle ".This stone mill head also can be made general bistrique usefulness, only needs side's cover and triangular prism replacing are got final product.
