Definitions

  • the invention consists in housing, while at the same time limiting the overall dimensions of, a spindle and grinding wheel mounting shaft equipped with a rotation mechanism which makes it possible to quickly vary the angle of the grinding wheel mounting shaft relative to the axis of the sleeve member of a vertical grinder.
  • the invention allows different machining processes, both traditional and non-traditional, to be performed in a short time on a workpiece. The workpiece needs to be located once only. The explanation for this is very simple. With the grinding wheel mounting shaft parallel to the axis of the sleeve member, small diameters and small shoulders can be machined in the traditional manner using cup grinding wheels.
  • the axis of the grinding wheel mounting spindle forms an angle ( ⁇ ) to the axis of the sleeve member, so that it is possible, with a suitable grinding wheel mounted, to machine simultaneously both the diameter and the shoulder, or to tangentially machine even large surfaces on the inside or outside of the workpiece.
  • a need which is felt particularly strongly by operators in the trade is that of having a vertical axis grinder which can be used to perform a plurality of operations simultaneously, such as grinding flat surfaces, shoulders and diameters without having to retool the machine, and whose overall size is particularly limited.
  • the very small size of the invented mechanism allows the sleeve member, in the preferred embodiment, to be inserted, for example, into a hole 310 mm in diameter with the grinding wheel mounting spindle in the position P1, and into a hole 306 mm in diameter P2 for a grindable length equal to the stroke of the sleeve member (700mm).
  • a vertical axis grinder is equipped with a workpiece holder table and a grinding wheel spindle head which works either with vertical axis or with horizontal axis.
  • the document GB 2226783 A discloses a vertical axis grinder, whose shaft can be inclined by screwing respectively unscrewing screws.
  • the whole wheel head and consequently the shaft can be inclined.
  • the grinding wheel has a first surface which is inclined at an angle to the axis of the selfsame grinding wheel and a second surface which is at night angles to the axis of the wheel.
  • a further aim of the invention is to provide a grinding machine which is highly versatile, that is to say, which allows a plurality of machine operations to be carried out with great precision.
  • a yet further aim is to propose a grinding method which allows shoulders and diameter surfaces of a mechanical part to be machined extremely precisely and rapidly.
  • the above aims are achieved by a grinding machine comprising the technical characteristics described in one or more claim 1 and by a method described in claim 9.
  • the numeral 1 denotes a grinding machine according to the invention.
  • Figures 1 and 2 illustrate the machine in its entirety in a front view and in a plan view, respectively.
  • the machine 1 comprises a workpiece holder table 19, preferably equipped with means for rotationally driving it and/or for moving it (of known type and therefore not described or illustrated).
  • the workpiece holder table 19 is preferably of the magnetic type, or in any case equipped with means for holding the workpiece 20 and configured to allow the workpiece 20 to be locked to the surface of the table 19.
  • the reference numeral 2 denotes a grinding head 2 or a work head 2 (clearly visible in Figure 3 and partly hidden in Figure 1 by a door which closes the operating area of the machine 1).
  • the grinding head 2 comprises a spindle 3 (hereinafter also referred to as grinding wheel 4), equipped with a shaft 5 connectable to the grinding wheel 4 to drive it in rotation to allow the workpiece 20 locked to the workpiece holder table 19 to be machined.
  • a spindle 3 hereinafter also referred to as grinding wheel 4
  • the grinding head 2 comprises an outer covering sleeve member 7 configured to house the spindle 3.
  • the sleeve member 7 comprises an internal cavity 24 for housing the spindle 3.
  • the internal housing cavity 24 is substantially cylindrical in shape; this shape will be described in more detail below.
  • the spindle 3 comprises a shell 8 which rotatably mounts the shaft 5.
  • the shell 8 is shaped to fit (with clearance) into the cavity 24 of the sleeve member 7.
  • the shaft 5 is supported by the shell 8 by means of bearings.
  • the shaft 5 can be driven in rotation relative to the shell 8. More specifically, the shaft 5 is connected to a motor, not illustrated, which drives the grinding wheel 4 in rotation.
  • the grinding wheel mounting shaft 5 may adopt two working positions, namely, a first working position P1, where the shaft 5 is vertical, and a second working position P2, where the shaft 5 is inclined at a predetermined acute angle ⁇ to a vertical direction Z so as to machine (tangentially) a first surface 17 (diameter surface), which is parallel with the vertical direction Z, and a second surface 18 (shoulder), which is at right angles to the vertical direction Z, simultaneously or almost simultaneously, as will become clearer as this description continues.
  • the machine 1 comprises inclining means 6 by which the shaft 5 can be set at an angle and which are configured to allow the shaft 5 to be positioned vertically in the first working position P1 and inclined at a predetermined acute angle ⁇ to the vertical direction Z in the second working position P2 such as to tangentially machine simultaneously a first surface 17 of a workpiece 20, where the first surface 17 is parallel with the vertical direction Z, and a second surface 18 of the workpiece 20, where the second surface 18 is at right angles to the vertical direction Z.

  • the ring 10 comprises an upper annular surface 21 and a lower annular surface 22, defining two respective parallel planes PP1 and PP2.
  • the work head 2 comprises a guide 42 for the ring 10.
  • the guide 42 is associated with the sleeve member 7. More specifically, in the example illustrated, the guide 42 is defined by the selfsame sleeve member 7 (in particular by an annular surface 44 which is inclined to the vertical at an angle equal to half the predetermined angle ⁇ ) and partly by a bushing 14 which forms part of the work head 2 and which can be associated removably with the sleeve member 7.
  • the guide 42 is configured to allow the shell 8 to rotate about the central axis X of the ring 10 to take the shaft 5 to one of either the first position P1 or the second position P2
  • the guide 42 defines means 11 by which the shell 8 is guided between the working positions P1, P2 and which are associated with the sleeve member 7.
  • the bushing 14 is cylindrical in shape. More specifically, it has a through hole 27 made in it. When the bushing 14 is coupled to the sleeve member 7, the shell 8 is inserted through the hole 27.
  • the bushing 14 comprises an upper annular surface 12.
  • a portion 23 of the outer lateral surface of the bushing 14 is provided with threading F1 configured to be screwed to a respective threaded portion 25 of the lateral surface of the cavity 24 of the sleeve member 7.
  • Another portion 26 of the outer lateral surface of the bushing 14 is provided with toothing F2, that is to say, it is circumferentially provided with teeth.
  • the cavity 24 comprises, at the bottom opening, a cylindrical portion 28 having a central axis which is inclined at an angle equal to half the predetermined angle ⁇ (angle ⁇ /2).
  • the threaded portion 25 of the sleeve member 7 is made at the cylindrical portion 28 whose central axis is inclined at an angle equal to half the predetermined angle ⁇ (angle ⁇ /2).
  • the work head 2 further comprises a pinion 29 which is meshed with the bushing 14 in order to drive it in rotation.
  • the pinion 29 is rotatably connected to the sleeve member 7. More specifically, it should be noted that the pinion 29 is provided with toothing which meshes with the toothing of the bushing 14 to form a gear. More generally speaking, the gear defines means 34 for driving the bushing 14 in rotation and which can be operated by the user in order to rotate the bushing 14 in such a way as to impart to the bushing 14 a translational movement within the cavity 24 (and more specifically, within the portion 28) along a direction K1 parallel to the axis of the cylindrical portion 28.
  • the sleeve member 7 has two radial holes 31 made in it (in the example illustrated, the holes 31 are located at 180° to each other).
  • the ring 10 also has peripherally made in it a pair of radial holes 30 (whose angular spacing from each other corresponds to that of the holes 31).
  • each pin 32 engages one radial hole 30 and one radial hole 31.
  • the pins 32 make it possible to stop the rotation of the shell 8 with respect to the sleeve member 7, that it to say, they prevent the rotation of the shell 8 relative to the sleeve member 7.
  • pins 32 define anti-rotation means 33 of the shell 8 relative to the sleeve member 7.
  • the pins 32 and the bushing 14 define means 9 for locking the shell 8 relative to the sleeve member 7 at the aforementioned positions (P1, P2).
  • the work head 2 also comprises a further ring 39, located at the opening of the cavity 24, and a cover 40 for closing the ring 39.
  • a protective guard 41 Also shown is a protective guard 41.
  • the ring 10 and the guide means 11 define, more in general, the inclining means 6 by which the shaft 5 is tilted between the first working position P1 and the second working position P2.
  • Figure 4 illustrates the shaft 5 in the first working position P1 (with the axis K vertical).
  • the machine 1 preferably has installed on it cylindrical grinding wheels 4 of the type labelled 4a in Figure 6 .
  • the machine 1 when fitted with grinding wheels of type 4a, can machine diameters (these machine operations are labelled 35c in Figure 6 ) as well as inclined surfaces (these machine operations are labelled 35a and 35d in Figure 6 ).
  • the entire work head 2 (that is, the sleeve member 7) of the machine 1 is inclined by an angle corresponding to that of the inclined surface 16 being machined.
  • the axis K of the shaft 5 is positioned so it is substantially parallel to the inclined surface 16 to be machined.
  • the machine 1 comprises further rotation means by which the sleeve member 7 is rotated about a direction Q (horizontal in the embodiment illustrated) at right angles to the vertical direction Z, and which are configured to allow the entire sleeve member 7 to be rotated in such a way that the axis K of the shaft 5 is parallel to an inclined surface 16 of the workpiece 20.
  • these rotation means allow the machine 1 to work conical surfaces 16 (machine operations 35a and 35d, Figure 6 ) with extreme precision.
  • the shaft axis K is aligned (positioned so it is inclined at the same angle to the vertical Z) with the surface 16 being machined and the grinding wheel 4 and the workpiece 20 are moved relative to each other along a direction parallel to the axis K of the selfsame shaft 5 (this may be done by moving the workpiece holder table 19 or the work head 2).
  • Figure 7 illustrates the shaft 5 with a grinding wheel of the type labelled 4b in Figure 6 .
  • the grinding wheel 4b has a lateral surface 36 which is inclined to its axis W, and an underside surface 37 which is substantially at right angles to its axis W.
  • the lateral surface 36 is inclined at the predetermined angle ⁇ to its axis W.
  • the underside surface 37 of the grinding wheel 4b is connected to the lateral surface by a surface 38 which is inclined (to the axis W) in the opposite direction to the surface 36.
  • the inclined surface 38 preferably makes a 90° angle with the lateral surface 36.
  • the grinding wheel 4b comprises two frustoconical portions: an upper portion T1 and a lower portion T2 (considerably smaller in volume).
  • the operator removes the pins 32 from the holes 30, thereby disengaging the shell 8 from the sleeve member (that is to say, removing the lock which prevents rotation of the shell 8 relative to the sleeve member 7).
  • the user After removing the pins 32, the user operates on the pinion 29 in such a way as to set it in rotation.
  • Rotating the pinion 29 (which, as mentioned above, is kinematically linked to the bushing 14) causes the bushing 14 to rotate relative to the sleeve member 7.
  • the bushing 14 since it is screwed to the sleeve member 7, is made to translate along the direction labelled K1 (more specifically, it is made to translate away from the inclined surface 44 of the sleeve member 7).
  • the shell 8 is made to rotate (manually in the example illustrated) by 180° about the axis X, which is inclined to the vertical direction Z by half the angle ⁇ (angle ⁇ /2)
  • this rotation is performed manually.
  • the inside lateral surface of the cavity 24 of the sleeve member 7 comprises a portion 15 (hereinafter referred to as surface 15) which is shaped to form an abutment stop for - preventing the rotation of - the shell 8.
  • the pins 32 guarantee that the shell 8 is angularly centred relative to the sleeve member 7 both in the first working position P1 and in the second working position P2.
  • the shaft 5 is inclined to a vertical direction Z at an angle corresponding to the predetermined angle ⁇ (in this regard, see the angle subtended between the shaft axis K and the vertical Z in Figure 7 ).
  • the predetermined angle ⁇ is an angle of 8°. Hence, half that angle (angle ⁇ /2) is 4°.
  • the angle is an acute angle (that is, smaller than 90°), and still more preferably, it is an angle less than 20°.
  • the pins 32 keep the shaft 5 in a predetermined position.
  • the grinding wheel 4b can machine diameters (surface 17) and shoulders (surface 18) simultaneously.
  • the machine 1 when in this configuration, can perform the operations labelled 35b and 35e, tangentially machining a shoulder (horizontal surface 18) and a diameter (vertical surface 17) almost simultaneously.
  • machine 1 can advantageously work on shoulders and inside diameters (machine operation 35e) even of small holes, without having to use shaft extensions connected to the shaft 5 (which inevitably lead to machining errors on account of misalignments with the axis K).
  • these shoulder and diameter machine operations are extremely precise, also because they are carried out without changing any tool or retooling the machine 1 in any way.
  • the ring 10 abuts on the top of it with the surface 44 of the sleeve member 7 and its underside with the surface 12 of the bushing 14.
  • the inclining means 6 are configured to rotate the shaft 5 between the first and second positions (P1, P2) about an axis X which is inclined at an angle corresponding to half the predetermined angle ⁇ to the vertical direction Z

  • they define the guide 42.
  • pins 32 determine the angular centring of the shell 8 relative to the sleeve member 7, guaranteeing that the shaft is precisely and securely positioned in both positions P1 and P2.

  • the method comprises the following steps:
  • the first surface 36 of the grinding wheel 4b is inclined at the predetermined angle ⁇ to the axis W of the selfsame grinding wheel 4b.
  • the grinding wheel 4b comprises a third surface 38 connecting the first surface 36 and the second surface 37 and inclined at an angle to the axis W.
  • the third surface 38 is at right angles to the first surface 36.
  • the method allows a shoulder (surface 18) and a diameter surface (surface 17) to be simultaneously machined tangentially in an extremely precise and rapid manner. Indeed, it is not necessary to retool the machine 1 in any way between one machine operation and the other, since the two can be performed substantially simultaneously and with the same tool 4b.
  • the third surface 38 machines the shoulder 18 - tangentially - while the first surface machines the diameter surface 17 - also tangentially.
  • Figure 8 illustrates a grinding wheel 4c having a first portion T3, whose characteristics are similar to those of the grinding wheel 4b, as well as a second, frustoconical upper portion T4.
  • the frustoconical upper portion T4 comprises an upper surface 46 which is parallel to the lower surface 37, and a connecting surface 45 between the upper surface 46 and the lateral surface 36.
