  • the prior art discloses a variety of tools for machining, such as for beveling the end of a tubular or round bar type piece.
  • One exemplary prior known tool is the angle grinder, comprising a rotating disc capable of beveling the end of a piece.
  • One objective of the invention is to eliminate or at least mitigate drawbacks related to the prior art.
  • the invention seeks to provide such an apparatus for machining a tubular or round bar type piece, particularly for beveling and straightening its end, wherein one and the same apparatus enables the convenient, safe and quick machining of tubular pieces varying in sizes as regards their diameters and/or wall thicknesses.
  • the apparatus for machining a tubular or round bar type piece such as for example for beveling and/or straightening the end of a piece, comprises a frame element, as well as support elements associated with the frame element, and a tool member, such as for example a blade, associated with at least one support element.
  • the support elements are adapted to be radially movable relative to the frame element towards the frame element's rotation axis, i.e. approaching each other, and away from the rotation axis, i.e. drawing away from each other.
  • the frame element has a groove for enabling said radial movement for each support element in radial direction.
  • the support elements can be extended for example to their extreme positions to set the same as far apart as possible, after which the apparatus can be placed around the end of a work object, for example a plastic pipe. This is followed by moving the support elements preferably towards the frame element's rotation axis, such that the support elements touch a surface of the workpiece, thus supporting the apparatus around the piece in a rotatable manner, whereby the tool member becomes preferably adapted to touch the workpiece at an angle and to perform the machining operation as said frame element is rotated axially around said frame element's rotation axis.
  • the angle of a tool member can be changed and tool members can be replaceable or double-sided to turn the same over upon wearing.
  • the support elements are adapted to be movable simultaneously towards the frame element's rotation axis (approaching) or away from the same (drawing away).
  • all support elements are moving simultaneously in an interdependent manner either towards or away from the rotation axis.
  • the apparatus further comprises also a guide element associated with the frame element for guiding the support elements with respect to the frame element, for example in the process of adjusting a distance of the support elements from the frame element's rotation axis.
  • the guide element has preferably grooves, along which the support elements are adapted to be radially movable relative to the frame element towards the frame element's rotation axis (approaching) and away from the same (drawing away).
  • the grooves are arcuate in terms of their geometry, the support elements being provided on the apparatus so as to slide not only along the frame element's radially extending grooves but also along the guide element's arcuate grooves.
  • the support elements travel along the guide element's arcuate grooves, thereby conducting, relative to the frame element's rotation axis and depending on which way the guide element is being turned, either an approaching or drawing away motion in the frame element's radial direction.
  • Said embodiment provides a very high speed, high precision and convenient way of adjusting the support elements symmetrically around a workpiece, most preferably for example with a single wrist movement.
  • the apparatus for example the frame element, be provided with a measurement scale arranged to enable adjusting the support elements by means of the measurement scale to comply directly with a piece of certain size.
  • the support element comprises preferably a wheel or roller, which is adapted to be rotatable around its axis and which is adapted to slide or roll along the surface of a piece as the latter is worked on.
  • the wheel or roller serving as a support element is most preferably adapted to touch an outer surface of the workpiece, but, according to a principle of the invention, especially in the process of machining hollow tubular pieces, the wheel or roller serving as a support element can also be brought to contact with an internal surface of the piece.
  • the apparatus comprises also a second tool member for straightening the end of a piece as said frame element is rotated axially around the frame element's rotation axis.
  • the second tool member or blade can be arranged for example in connection with the support element in such a way that, when adapting said support element to comply with the dimensions of a workpiece, said second tool member is preferably carried along with the support element to an optimal position.
  • the apparatus comprises at least three support elements, already providing adequate support for the apparatus rotating around a workpiece during the machining operation. Even more preferably, the number of support elements is four, providing a higher quality support and steadiness of rotation around a piece. The number of support elements can be even higher than what has been described here. It should be noted that the apparatus has at least one tool member, but that each support element may also be provided with at least one tool member either for beveling the end of a piece at its external surface and/or with at least one second tool member for straightening the end of a piece.
  • the apparatus comprises preferably also clamping means for securing the support elements in said lateral direction of the frame element, such that said elements would support the apparatus through the entire machining process instead of sliding, for example in response to centrifugal force, to an outer periphery of the frame element.
  • the clamping means can be implemented for example by a wing nut associated with each support element or by a clamping element common to the support elements, such as by a rotatably lockable and releasable clamping ring.
  • the clamping means can be implemented by means of a friction brake type clamping element, wherein the friction brake can be released for the duration of moving the support elements and then engaged for securing the support elements in position.
  • the friction brake type clamping element can be implemented for example by friction surfaces between the support elements and the frame element or between other such surfaces, the relative friction force thereof being adjustable for engaging and releasing the friction brake.
  • the apparatus according to the invention also enables the use of other types of clamping mechanisms, such as for example cotter pins or a ratchet system, which enable securing the clamping means at a desired spot for the duration of a machining process as opposed to sliding off for example as a result of centrifugal force.
  • the frame element and the guide element are composed of most preferably co-directional planar components with a common rotation axis.
  • a planar guard component for blocking the access of cuttings between the frame element and the guide element.
  • the guard component is also provided with grooves, along which the support elements are adapted to travel upon rotating the guide element axially with respect to the rotation axis of the frame element and the guide element.
  • the guard component's grooves are arcuate in terms of their, geometry.
  • guard component's arcuate grooves are set to curve in a direction opposite to the corresponding guide element's grooves or at least diverging from the guide element's grooves, the result is a maximal protection effect for blocking the cuttings, because, at any time in the direction of the frame element's rotation axis there is a hole only in that particular location at which the support element extends across both the frame element's groove, guide element's groove and the guard component's groove.
