Description
Technical field
The present invention relates to a kind of Filings-removing polishing grinder head and buffing machine of brick body, particularly a kind of in making ceramic tile, floor tile, the brick body polishing machine that can carry out the grinding head for polishing of debris removal polishing and adopt this grinding head for polishing to make the brick surface.
Background technology
In the production of ceramic tile, floor tile, need carry out grinding and polishing to the brick surface that sintering finishes usually and handle, its process is that the brick body is lain on the working position, utilizes grinding head for polishing that the brick surface is carried out by thick to thin multiple tracks grinding and polishing processing.
The structure of existing grinding head for polishing as shown in Figure 1 and Figure 2, it comprises rotor 1a, evenly is distributed with a plurality of abrasive holder 2a in the outer ring week of rotor 1a, the bottom clamping of abrasive holder 2a has special-purpose abrasive material piece 21a.Described abrasive holder 2a connects by the semiaxis 11a that can back and forth rotate and is located on the rotor 1a.Be provided with the transmission mechanism (not shown) that connects with semiaxis 11a in the inside of rotor 1a, abrasive holder 2a can be driven at work, by semiaxis 11a towards the reciprocal oscillating motion of left and right directions.Also vertically run through to be provided with a wash tub pipe 12a in the inside of rotor 1a, the top of this wash tub pipe 12a is provided with flange 121a, and flange 121a is used for whole grinding head for polishing is connected drive end.In carrying out the grinding and polishing operation of brick body, grinding head for polishing horizontally rotates on the brick surface, simultaneously, the reciprocal oscillating motion of abrasive holder 2a, under the rotation aggregate motion of the revolution of grinding head for polishing and abrasive holder 2a, the brick surface obtains grinding and polishing, and flushing water passed rotor 1a according to arrow line direction among the figure by wash tub pipe 12a chip removal flushing was carried out in the brick surface this moment.
The structure of above-mentioned existing grinding head for polishing exists some shortcomings, brick surface defective of low quality when having caused the brick surface ground or polish, its main cause is that flushing water can't grind the bits material that falls with the brick surface and thoroughly remove, and causes the secondary in the grinding and polishing to scratch.Figure 3 shows that the partial enlarged drawing when grinding and polishing is carried out in the brick surface, among the figure, the surface of the brick body 3a that amplifies is actually rugged and has many spikes, after the special-purpose abrasive material piece 21a spike cutting that some are higher falls, these bigger bits material 31a may drop on the surperficial lower of brick body 3a, though flushing water can carry out the chip removal flushing, but because hydraulic pressure is lower and the surface of vertical impact brick body 3, the flushing dead angle appears easily, the bits material 31a that is rinsed be generally pulverous or granularity less, and those bigger bits material 31a still are trapped in the surface of brick body 3a.When special-purpose abrasive material piece 21a moves to bits material 31a delay place once more, bits material 31a can be clamped between the surface of special-purpose abrasive material piece 21a and brick body 3a mobile, because the hardness of bits material 31a self is not less than the hardness on brick body 3a surface, and the granularity of some bits material 31a goes up the granularity of abrasive material greater than special-purpose abrasive material piece 21a, therefore often cause the secondary in the grinding and polishing to scratch, and the groove mark that scratches often is difficult to repair to the surface of brick body 3a.
Cause the brick surface ground or polish adding the defect problem that occurs man-hour in order to solve above-mentioned deficiency because of the grinding head for polishing structure, the polishing machine of manufacturer's making at present, usually take the multiple tracks grinding and polishing, the mode that reduces the abrasive grain degree is step by step ground repeatedly to the brick surface.The part-structure schematic diagram that is habitual at present polishing machine shown in Figure 4.Among the figure, the frame 100a of polishing machine is provided with to move and transmits workbench 6a, a plurality of grinding head for polishing 10a serial is arranged side by side above mobile transmission workbench 6a, brick body to be ground direction shown in the arrow line in the figure moves horizontally to next machining cell from first machining cell at first grinding head for polishing 10a place, in each machining cell, these grinding head for polishing 10a carries out grinding and polishing one by one to the brick body respectively.In order to make the brick surface reach the fineness of regulation, the granularity of the special-purpose abrasive material piece on the grinding head for polishing 10a is taked the mode that reduces step by step, for example the first order adopts the special-purpose abrasive material piece of 30a purpose, the special-purpose abrasive material piece of 60a purpose is adopted in the second level, the rest may be inferred, and in the end one-level adopts the special-purpose abrasive material piece of 1800a purpose.Because the brick surface has the groove mark that above-mentioned secondary scratches in grinding and polishing processing, therefore, when setting the granularity size of the special-purpose abrasive material piece of each grade, can only take in adjacent several machining cells, to adopt the identical special-purpose abrasive material piece of order number, promptly, the brick body is carried out repeatedly grinding and polishing under the special-purpose abrasive material piece of identical order number, so, often make on the frame 100a a fairly large number of grinding head for polishing must be set, nearly 40 of grinding head for polishing quantity on the polishing machine for example commonly used, the power of the drive motors 7a of each grinding head for polishing is generally tens kilowatts.Even like this, still can not thoroughly eliminate the groove mark that secondary scratches, because in old darker groove mark is removed, also can produce new more shallow groove mark, in theory, the quantity of grinding head for polishing is many more, and the size of the granularity of the special-purpose abrasive material piece of afterbody is more little, the fineness of brick surface could be high more, but, so not only can cause great waste, and prolong the machining period of brick body greatly the energy, increased the manufacturing cost of brick body, moreover, because the thickness of the surface layer processed of brick surface is limited, therefore, a large amount of repeatedly grindings will certainly destroy surface layer and expose brick body internal layer, forms builder or brick inferior.
