Description
- The present invention relates to apparatus for conditioning a surface of an object particularly, but not exclusively, the surface of a cylinder such as a pipe.
- When a metallic pipe is to be joined to another pipe or other component by means of a weld or the like it is generally necessary to condition the internal and/or external surface of the pipe both prior to and after the joining operation is performed. Most importantly, it is necessary to clean the surfaces at the region where the join is to be made in order to remove dirt and oxidation that may have a detrimental effect on the quality of the weld. It may also be necessary to prepare the ends to be joined by removing sharp edges or by fine machining of the ends to facilitate the welding process. After the weld has been formed it is often necessary to remove any weld material that projects from the surface of the pipe by grinding and polishing.
- The term “conditioning” is used herein to refer to treatments including grinding, polishing, deburring, rust or scale removal, chamfering, facing and undercutting. Such operations are conventionally performed manually by using abrasive paper or board or, alternatively, by using a hand-held power tool having an elongate circulating abrasive belt or a rotating abrasive disc. Both the above mentioned techniques require significant effort and are time consuming particularly when both the internal and external surfaces of each pipe require conditioning before and after welding. In certain applications such as the construction, servicing or maintenance of industrial boilers large volumes of pipe have to be conditioned and the task is labour intensive. Moreover it is often difficult to condition effectively certain pipes in-situ in circumstances where access is restricted.

- Referring now to FIGS. 1 and 2, a first embodiment of the
rotary tool 1 comprises anannular member 2 comprising an axially extending wall on the inner surface of which are formed a plurality of equi-angularly spaced, axially extendinggrooves 3, eachgroove 3 configured to receive in releasable engagement a conditioning member such as one of those shown in FIGS. 14 and 15. The wall surrounds aspace 4 in which a workpiece is to be received. Several tools may be provided each having different longitudinal and radial dimensions ofannular member 2 so as to receive objects of differing dimensions. - FIG. 3 illustrates a second embodiment of the tool where the annular member comprises four releasably
connectable sections 5. Eachsection 5 is identical and is semi-cylindrical. Thesections 5 are arranged in two pairs, the sections of each pair combining to form a completeannular member 6, as shown in FIG. 4, with six axially extendinggrooves 7 on the inner surface of each cylinder. The pairs of sections are angularly offset by one groove and are held together by insertion of conditioning members into thegrooves 7, FIG. 4 shows the tool when assembled, the conditioning members being omitted for clarity. It is to be appreciated that the rotary tool may have different longitudinal and radial dimensions ofsections 5 so as to receive objects of differing dimensions. - FIG. 5 illustrates a rotary tool having the same construction as FIG. 1, wherein an
annular member 2 comprising an axially extending wall has a plurality of equi-angularly spaced, axially extendinggrooves 3 formed on its inner surface, but additionally shows adrive shaft 8 for connection to a drive unit. Thedrive shaft 8 is connected to the axially extending wall by means of a further radially extending wall (not shown). - The embodiment of the rotary tool shown in FIGS. 6 and 7 differs from those described above in that it has a plurality of
radial slots 9. Eachradial slot 9 is configured to receive any one of the conditioning members shown in FIGS. 14 and 15. Eachslot 9 is open to allow a conditioning member to be inserted from the outermost surface of theannular member 10. When in use, the conditioning member inslot 9 engages the end of of the object to be conditioned. - FIG. 8 is an end view of a further embodiment of the apparatus. In this embodiment the tool has a

Conditioningmembers 14 are releasably received ingrooves 15 of theannular member 12. Each conditioning member has a spine (for example, 16) for location in a groove (for example, 15) and a radially projecting abrasive member (for example, 17). Theconditioning members 14 are used to condition the outer circumferential surface of a pipe as described below.Further conditioning members 18 are connected intogrooves 19 in the outer surface of thebore member 11. Thegrooves 19 are disposed so that conditioningmembers 18 project in to the space betweenconditioning members 14. Theconditioning members 18 are used to condition the inner circumferential surface of a pipe. It is to be understood that embodiments of the apparatus would be provided comprising different longitudinal and radial dimensions ofcentral bore member 11 configured to engage objects of differing dimensions. Conditioningmembers 20 are connected to the inner surface of theannular housing 12 utilising theradial slots 9 shown in FIGS. 6 and 7 (not shown in FIG. 8) and are used to condition the end face of a pipe. - FIGS. 9, 10 and11 illustrate an embodiment of the apparatus, such as that shown in FIG. 5, in use. The
rotary tool 1 is connected to adrive unit 21 utilising thedrive shaft 8. FIG. 9 illustrates the apparats prior to engagement of apipe 22 to be conditioned. The pipe is then inserted into thespace 4 and the conditioning members flex to accommodate its insertion FIG. 10). The rotary tool is driven in rotation by thedrive unit 21 in the direction of arrow A during engagement of thepipe 22. As the tool rotates the conditioning members (not shown) pass over the outside surface of thepipe 22 thereby conditioning the surface. If the embodiment of FIG. 8 is used, wherein the tool comprises acylindrical bore member 11 coaxially disposed inside the wall of theannular member 12, then theconditioning members 18 additionally pass over the inside surface of the pipe thereby conditioning it simultaneously with the outside surface. FIG. 11 illustrates the apparatus following engagement of thepipe 22. Thedarkened end 23 of thepipe 22 in FIG. 11 represents the conditioned exterior surface. - FIGS.12, 13(a) and 13(b) show the embodiment of the apparatus of FIG. 4, in use. The tool is assembled from the plurality of
sections 5 around apipe 24 to be conditioned. The outside surface of theannular member 6 is frictionally engaged with arotary drive wheel 25 of arotary drive unit 26 during engagement of thepipe 24. Mounted on either side of thewheel 25 is asupport member 27 that abuts thepipe 24 during engagement of the rotary tool by therotary drive wheel 25. Thesupport members 27 each have arecess 28 that receives the pipe surface. - FIG. 14 illustrates various embodiments of each
conditioning member conditioning member rigid spine 29 of cylindrical section that is complement to the shape of a groove (for example,groove 3 of FIG. 1) and a substantially flexibleabrasive member 30 received in thespine 29 and projecting radially therefrom. A plurality of abrasive members may be used with eachspine 29 so that as a leading abrasive member wears a fresh member is revealed behind it. The abrasive member of each conditioning member may be substantially rectangular in side view (FIGS. 14(a), 14(c), 14(e) and 14(f)) possessing a leadingedge 31 parallel to thespine 29 or may comprise aleading edge 32/33 that is at an angle to the spine 29 (FIGS. 14(b) and 14(d)).Abrasive members 30 constructed of different materials may be provided, for example, FIG. 14(a) illustrates anabrasive member 30 with a fine abrasive surface, FIG. 14(c) illustrates anabrasive member 30 with a combination of more fine and more coarse abrasive surfaces, FIG. 14(e) illustrates anabrasive member 30 with a coarse abrasive surface and FIG. 14(f) illustrates anabrasive member 30 with an alternative arrangement of more fine and more coarse abrasive surfaces to that in FIG. 14(c). This range of different embodiments allows a user to select theconditioning member 30 with the most suitable combination of size, shape, flexibility and abrasive characteristics for the job to be performed. - Although the
spine 29 is of circular cross-section in these embodiments, it may be otherwise shaped. - The apparatus of the present invention is versatile in that it may be used to condition different surfaces of a pipe independently or simultaneously. For example, if all three sets of
conditioning members annular member bore member 11 allowing the user to select the particular embodiment which best suits the job to be performed. The range of conditioning members (FIGS. 14 and 15) provided permits additional user customisation of the apparatus. - In an embodiment not shown in the drawings, means may be provided to bias each conditioning member towards the axis of rotation of the rotary tool thereby forcing each conditioning member against the surface to be conditioned. In a one embodiment, the biasing means may comprise a stream of compressed air. In another embodiment, the biasing means may be provided by magnetic attraction.
