Definitions

  • the present invention relates to polishing apparatus and polishing picks employed for such apparatus, principally for polishing concrete surfaces such as floors . It will be convenient to describe the present invention as it applies to concrete polishing but it will be appreciated by those skilled in the art of the present invention that the invention is not limited to concrete polishing and could, for example, polishing surfaces other than concrete, such as ceramic, clay, stone, terrazzo and asphalt .
  • Polished concrete can be suitable for factory and warehouse floors, because it is hard wearing, easy to clean, resistant to oils and acids and the like and can be readily painted or marked as may be required in such commercial premises .
  • polished concrete flooring is also gaining popularity in domestic residences, such as warehouse apartments . Polished concrete has become an alternative to other surface materials such as marble, paving tiles and linoleum or carpet .
  • a polishing pick including: a cylindrical shank, wherein at least a part of the shank is adapted for receipt within a bore of a polishing apparatus; a polishing substrate suitable for engaging and polishing the surface to be polished, wherein the substrate is attached to an opposite end of the shank to that received by the bore; and securing means associated with the shank, wherein when the shank is inserted into the bore the securing means retains the shank in the bore in an axial direction and allows free rotation of the shank relative to the bore .
  • the securing means can reliably secure the polishing pick to a polishing head of a polishing apparatus by receipt of the shank within the bore of such a head.
  • some prior art polishing picks have a tapered bore into which the shank of the pick is driven and it is the shank which directly and frictionally engages the bore surface to maintain the polishing pick in position during use .
  • One of the difficulties with this type of prior art polishing pick is that the shank is driven into the bore using a mallet, hammer or hydraulic piston, and the act of driving one of the picks in a bore can cause one or more of the other polishing picks already fitted to become loose .
  • Another advantage of the present invention over this type of the prior art polishing pick is that the securing means of the present invention allows the polishing pick to freely rotate during a polishing operation and this promotes more even wear of the polishing substrate so that the life of the polishing pick is maximised.
  • the securing means preferably includes a sleeve which is secured to and loosely disposed about the shank so that the shank can freely rotate relative to the sleeve .
  • the sleeve is arranged to frictionally engage the surface of a bore of a polishing head assembly or machine and in this manner, the shank can be secured against removal from the bore, yet maintaining the required ability to freely rotate . It is the outer surface of the sleeve which engages the inside surface of the bore .
  • the sleeve be formed with a lengthwise split that permits the sleeve to be at least partially deformed or collapsed radially inwardly for insertion into a bore .
  • the sleeve can be released to resiliently expand or recoil radially outwardly so that it frictionally engages the bore surface and thereby fix or retain the polishing pick in position.
  • the shank In order to secure the shank axially to the sleeve, and in turn axially to the bore, it is preferred that the shank have an annular groove and the sleeve have at least one projection for receipt within the groove .
  • shank of the pick also include a platform at an end thereof for supporting the polishing substrate .
  • the platform and the polishing substrate have a circular cross-section. It is also preferred that the diameter of the platform and the polishing substrate be either substantially the same, or that the diameter of the platform be less than, preferably slightly less than, the diameter of the polishing substrate. In a preferred arrangement, the diameter of the polishing substrate is about 50 mm although it could easily be larger or smaller. The diameter of the platform can be slightly smaller than that of the polishing substrate, or it can be about the same diameter, or the platform can be large enough to encase the substrate . In the last arrangement, the polishing substrate can be partially received within a recess in the platform.
  • the polishing substrate preferably is industrial diamond, although the following polishing substrate materials could also be employed: poly ⁇ rystalline diamond, silicon diamond or tungsten carbide . Moreover, the polishing substrate preferably includes any one or a combination of the above mentioned materials .
  • locating means be provided to locate or align the polishing substrate in position relative to the platform before the polishing substrate is fixed to the platform.
  • the locating means comprise a lug which projects from one of the platform or the polishing substrate and which is arranged for receipt within an opening provided in the other of the platform or the polishing substrate.
  • the lug can be a key or a pip, or any other suitable projection.
  • the polishing substrate For properly fixing the polishing substrate to the platform, it is preferred that the polishing substrate have a generally planar base surface which sits flush against a generally planar support surface of the platform.
  • a contact area between the polishing substrate and the platform is across substantially the full base surface of the polishing substrate so that a broad contact area is provided.
  • the manner of attaching the polishing substrate to the platform is by brazing or by other suitable adhesive materials .
  • a polishing head assembly includes a plurality of bores that each receive shanks of the polishing picks, when the picks are inserted into the bores , the securing means associated with the shanks retains or secures the shanks in an axial direction in the bore while allowing the shank to freely rotate therein.
  • the head assembly is rotatably driven with the polishing substrates of the picks contacting or facing the surface to be polished. As this occurs, each pick is able to freely rotate in response interaction between the polishing substrate and the surface being polished.
  • a method of polishing a surface including rotating the polishing head assembly described above with the polishing picks contacting or facing the surface to be polished.
  • a polishing pick which comprises : a cylindrical shank for receipt within a bore of a polishing apparatus ; a platform for supporting a polishing substrate extending from one end of the shank; a polishing substrate attached to the platform; and securing means associated with the shank to secure the shank within the bore of the polishing apparatus and to facilitate free rotation of the shank relative to the bore of the polishing apparatus when the shank is inserted into the bore .
  • the platform and the shank may be integrally formed such that the platform may be regarded as part of, or forming part of the shank.
  • Figure 1 is a side view of a polishing pick according to one embodiment of the invention.
  • Figure 2 is a side view of a polishing head assembly including a plurality of the polishing picks shown in Figure 1.
  • a polishing pick 10 includes a shank 11, a platform 12 and a polishing substrate 13.
  • each of the shank 11, the platform 12 and the polishing substrate 13 are cylindrical and coaxial .
  • the shank 11 and the platform 12 can be formed as integral components, and preferable they are formed of steel .
  • the polishing substrate 13 can be of any suitable material depending on the particular purpose to which the polishing pick is to be applied, and if the material being polished is concrete, preferably the polishing substrate is an industrial diamond material .
  • the axial height H p of the platform 12 is about equal to the axial height H ps of the polishing substrate .
  • the typical platform height H p and the axial height H ps of the polishing substrate could have dimensions very different to that shown.
  • the H p could be twice that of the height H ps and vice versa.
  • the diameters of both of the platform 12 and the polishing substrate 13 are about the same, or as shown, that the diameter of the polishing substrate 13 slightly exceeds that of the platform 12. It is however acceptable for the diameter of the platform 12 to be greater than the diameter of the polishing substrate 13.
  • the polishing pick 10 includes securing means associated with the shaft 11 and in Figure 1, the securing means comprises a sleeve 14 which is loosely disposed about the shank 11 but is secured axially thereto .
  • the shank 11 can rotate relative to the sleeve 14 about its lengthwise axis, but is secured against significant axial movement relative to the sleeve 14.
  • the sleeve 14 is secured axially to the shank 11, by receipt of a radially inwardly extending protrusion 15 which extends into a annular groove 16 formed in the shank 11.
  • the sleeve 14 includes a lengthwise split 17 and by the provision of the split 17 , sleeve 14 can be at least partially collapsed radially inwardly, to insert the sleeve 14 and the shank 11 into the bore of a polishing head assembly. Once inserted, the sleeve 14 can be allowed to resiliently expand, released, or allowed to expand outwardly radially such that the sleeve frictionally engages the surface of the bore and that frictional engagement secures the sleeve 14 within the bore and so secures the shank 11 against removal from the bore .
  • the shank 11 is rotatable within the bore by this arrangement and allows the polishing pick 10 to rotate during a polishing operation.
  • a flange 18 is provided and this can be loosely- fitted or fixedly secured about the sleeve 14 and is in engagement with the underneath surface 19 of the platform 12.
  • the flange 18 can provide shock absorption qualities between the platform 12 and the polishing head assembly 20 to which the polishing pick 10 is fitted.
  • a polishing head assembly 20 includes : a circular base 22 ; a plurality of mounting knuckles 26 which define cylindrical bores 23
  • the shanks are secured or retained to the sleeves in the axial direction identified by line A to A by way of an inwardly protruding lug on the inner surface of the sleeve 14 which is received by an annular groove on the shank 11.
  • the lug and annular groove allowing free rotation of the shank 11 inside the sleeve 14.
  • the knuckles 26 and, therefore, the bores 23 inside the knuckles 26 and the picks 10 inserted into the bores are oriented substantially perpendicular to the general plane of the base 22.
  • the mounting knuckles 36 can be fixed to the base 32 by any suitable arrangement, and in the embodiment illustrated are fixed to the base 32 by welding.
  • each polishing pick 10 includes a working surface 21 at the end of the shanks
  • the working surfaces 21 are essentially co-planar and include a central recessed portion 21B that is defined by a raised outer annular ring 21A. In this form of working surface, the surface has less wear area and therefore can wear for more consistent polishing pattern.
  • the polishing head 20 is rotatably driven about an axis define by line B to B and the polishing picks freely rotate about an axis defined by line A to A. Rotation of the polishing picks will be determined by forces on the picks resulting from interaction between the polishing picks and the surfacing being polished.
