Abstract

A grinding head of stone grinding machinery, the extension line of the central line of each grinding block shaft (16) is intersected with the extension line of the central line of the grinding head inner shaft (7) at one point, a spring (15) is arranged between a planet sleeve shaft (17) and the grinding block shaft (16), and a grinding block (18) is in a conical ring shape. When the grinding head is used for grinding stone, under the same grinding head pressure, the pressure intensity borne by the plate is much larger than that of a conventional grinding head, so that the grinding efficiency is high, the grinding blocks are uniformly worn, the glossiness of the ground plate is high, the yield of the stone plate can be improved, and the stone plate with edges cut firstly can be ground.

Description

Lapping-head of stone-lapping machine

The utility model belongs to the attrition process machinery field of building stones.

Bistrique is used in modal stone grinding processing, all employing face contact grindings during abrading block grinding stone material, and the contact area between abrading block and the processed plate is bigger.In order to improve grinding rate, generally all strengthen the pressure of bistrique to processed plate as far as possible; But, cause processed plate to break easily if pressure is excessive.Though from the thin plate production line that Italy introduces, adopted planet abrading block bistrique in China, make by the edge of nog plate and core glossiness to be more or less the same, Grinding Quality is better, can grind the slabstone of cutting edge earlier; But because it still grinds for the face contact, even if abrading block is very big to the pressure of slabstone, but pressure is still little, has hindered the further raising of grinding efficiency.＜granite in slab grinder〉(patent No. 88209700) of this research institute invention and＜planet swing abrading block granite grinding mill〉(patent No. 89220164), abrading block is changed over line contact processing to the processing of the grinding cutting of slabstone by face contact processing, strengthened the pressure of abrading block cutting edge, thereby increased substantially the efficient and the crudy of grinding slabstone; But the abrading block of preceding a kind of grinding machine can not rotation commutation, abrading block is by the part wearing and tearing earlier of bistrique outer rim, it is low to grind slabstone edge glossiness, thereby can not grind the slabstone of cutting edge earlier; A kind of grinding machine in back has overcome above-mentioned shortcoming, can grind and cut the big thin plate of specification and the side cut hair plates of standard specification, but because the geomery error of the abrading block of producing both at home and abroad is all bigger at present, in the first few minutes that new abrading block has just used, because the off size requirement of abrading block, make bistrique play and vibrating up and down, when abrading block entad forms arc surfaced naturally in grinding, vibration just alleviates, and it is particularly unfavorable that this phenomenon is ground thin plate.

The purpose of this utility model provides a kind of grinding efficiency height, grind that stone material is highly polished, the slabstone edge is consistent with the central glossiness of plate, and the bistrique vibration less, the bistrique of good stability.

The utility model is realized its purpose as follows: the extended line of axle 8 center lines intersects at a point in the extended line of each root abrading block axle 16 center line in the grinding head box body 10 and the bistrique; Planet sleeve 17 is fixedlyed connected with the bottom of abrading block axle 16, and between the top of abrading block axle spring 15 is arranged, and being fixed between planet quill gear 13 and the bistrique mandrel 11 on the planet sleeve 17 has grinding head core shaft gear 12 to be connected; It is circular that abrading block 18 is the conical surface.

Because abrading block of the present utility model is the line contact with contacting of processed slabstone when grinding, and the length of contact wire is than the weak point of aforementioned two kinds of grinding machines being invented, the various grinding machine contact-making surfaces of specific surface contact are littler, therefore under the situation of identical wheelhead pressure, slabstone suffered pressure when grinding is big especially, thereby the grinding capacity of the grinding machine that adopts the utility model bistrique is significantly improved, and owing to have only the part abrading block of close bistrique outer rim to carry out grinding, grinding speed is big on the processed plate face, speed difference is little, the grinding efficiency height, the abrading block wearing and tearing evenly, the glossiness of the sheet material center and peripheral that grinds is all high, has improved lumber recovery when grinding untrained hair plates, can also grind the slabstone that cuts the limit earlier.

Embodiment further specifies the utility model below in conjunction with accompanying drawing:

Fig. 1 is the transmission mechanism and the bistrique box structure schematic diagram of this stone grinding machine bistrique.

Axle 7 one ends are fixedlyed connected with small belt pulley 2, spline sleeve 1 in the bistrique, the other end is connected with bistrique mandrel 11, planet sleeve 17 lower inside are fixedlyed connected with abrading block axle 16, spring 15 is arranged in the inside upper part, fixedly connected with planet quill gear 13 in the outside, grinding head core shaft gear 12 is fixedly mounted on the bistrique mandrel 11; Bistrique outer shaft 8 tops are connected with spline sleeve 4 that is positioned at spline housing axle bearing seat 5 and big belt pulley 3, fixedly connected with grinding head box body 10 in the bottom.Fixedly connected with spline housing axle bearing seat 5 in bistrique lifting fairlead 6 tops, the lower end is connected with feather key 20 with bistrique outer shaft bearing block 9.Axle 7 center line extended lines intersect at a bit of bistrique below in the center extended line of each abrading block axle 16 and the bistrique.Behind the electric motor starting, big small belt pulley rotates with friction speed, small belt pulley 1 drives axle 7 in the bistrique, bistrique mandrel 11, grinding head core shaft gear 12, planet quill gear 13, abrading block axle 16 and abrading block 18 and rotates, when grinding head box body 10 drops to when contacting with processed slabstone, because the center line of axle 7 is not parallel in the center line of abrading block axle 16 and the bistrique, have only part could contact and carry out grinding with slabstone 19 in the abrading block 18 by grinding head box body 10 outer rims, because the rotation of abrading block, abrading block and slabstone contact and cutting point constantly changes, so abrading block is subjected to uniform wear.When axle 7 rotates in small belt pulley 2 drive bistriques, big belt pulley 3 drives bistrique outer shaft 8 and grinding head box body 10 is rotated, because big small belt pulley speed is rotated all different with the interior outer shaft of bistrique, cause the bistrique case also different with the abrading block rotating speed, abrading block rotation just have simultaneously have higher line speed, the revolution of shaft centre line in the line bistrique.Since abrading block with high even velocity carry out grinding, and because spring 15 is arranged, abrading block can flexiblely move, therefore use the grinding machine of this bistrique that high grinding speed is not only arranged, and the plate glossiness that grinds is good, whole plate glossiness differs in the 2-3 degree, and the wearing and tearing of abrading block are also very even, realized making full use of of abrading block.
