Definitions
- the invention relates to a portable grinding machine with a motor-driven drive shaft and a quick-action clamping device for a grinding tool, in which the quick-action clamping device comprises a spindle which is coaxial with the drive shaft and which braces against the drive shaft in the axial direction via a spring and by means of a clamping lever in the axial direction is displaceable relative to the drive shaft, an outer free end of the spindle holding the grinding tool, which can be removed from the free end in a release position when the free end of the spindle is extended and the spring is tensioned, and partially and in a clamping position when the free end of the spindle is retracted relaxed spring is in a rotationally fixed connection with the drive shaft.
- the quick-action clamping device comprises a spindle which is coaxial with the drive shaft and which braces against the drive shaft in the axial direction via a spring and by means of a clamping lever in the axial direction is displaceable relative to the drive shaft, an outer free end of the spindle holding
- a grinding machine of the type mentioned above is known from EP-OS 152 564.
- the known grinding machine is an angle grinding machine and the grinding tool is a rigid grinding wheel.
- the free end of the spindle protrudes from the grinding machine housing and the grinding wheel can be screwed onto the free end of the spindle.
- this is done in that the projecting free end of the spindle is provided with a threaded section which extends through the grinding wheel and on which a fastening nut can be screwed on from the outside and which covers the grinding wheel in its central region.
- the protruding end of the spindle is provided with a central bore, at the bottom of which there is a collet-like element with an internal threaded bore.
- a screw bolt the thickened end of which covers the central area of the grinding wheel, can be inserted from the outside through a central opening in the grinding wheel and inserted into the central bore of the spindle.
- the screw bolt carries at its inner free end a threaded section which engages in the collet-like element.
- Similar arrangement is used, in which a screw bolt is screwed into a central bore of the drive spindle. However, there is still a fastening sleeve between the thickened outer end of the screw bolt and the grinding wheel.
- a portable grinding machine of another type is known from EP 0 147 545, in which a bayonet connection is provided for the detachable fastening of a grinding wheel.
- the invention has for its object to develop a grinding machine of the type mentioned in such a way that the fixing process of the grinding tool is simplified.
- the free end is designed as a bayonet end, which extends through the grinding tool, that a fastening sleeve with a bayonet opening can be placed on the bayonet end from the outside , wherein the fastening sleeve partially covers the grinding tool from the outside, that the bayonet end has a first, outer Bayonet section of larger cross-sectional area and a second, inner bayonet section of smaller cross-sectional area that the cross-sectional shape of the first bayonet section has that of a regular triangle with three straight and three circular sections, that the cross-sectional shape of the second bayonet section has three circular sections with the radius of the inner circle of the triangle and 60 ° circumferential angle, three first straight sections that are aligned with the straight sections of the triangle and take up half of their width, and three second straight sections that connect at 120 ° to the first straight sections and have their width, and that the bayonet Opening of the fastening slee
- a bayonet mount is created that is simple in shape and therefore reliable in long-term use, especially taking into account the harsh operating conditions of grinding machines, for example angle grinders.
- the configuration mentioned has the advantage that the fastening sleeve on the bayonet end is simple Attachment and twisting can be fixed without the fastening sleeve having to be moved outward again by an axial amount, as is the case with some bayonet sockets.
- the grinding tool can be designed as a brush tool on which the fastening sleeve with its bayonet opening is provided.
- the disc-shaped grinding tool comprises a flexible grinding plate which has an inner region with an inner-conical contact surface for an abrasive paper, the fastening sleeve comprising an outer-conical section for pressing the sanding paper against the inner-conical contact surface.
- the axial length of the spring is a multiple, preferably 3 to 10 times the axial height of the inner conical contact surface.
- This measure has the advantage that a reliable clamping of the sanding paper on the flexible sanding plate is possible with such a long stroke clamping device.
- This measure has the advantage that, even if the sanding paper is loosely placed on the flexible sanding plate, it is reliably tensioned under frictional engagement.
- the bayonet end rests on the bayonet opening without a slope over radial end faces.
- This measure has the advantage that the construction and thus the manufacture of the bayonet is simplified because the fastening sleeve with its bayonet opening is only rotated in the circumferential direction relative to the bayonet end of the free end of the spindle, but does not have to be screwed onto it.
- This is achieved in particular in the previously described exemplary embodiment, in which a wedge effect occurs in the circumferential direction of the bayonet connection, with which the fastening sleeve is fastened to the bayonet end of the spindle without having to be screwed.
- the bayonet end is provided at the free end of the spindle with an extension which, when the bayonet connection is closed, positively engages in an outer opening of the bayonet sleeve.
- This measure has the advantage that the positively active elements of the bayonet connection are secured against contamination, because the extension in the outer opening represents a closure of the inner elements of the bayonet connection with respect to the outside.
- the grinding tool has bristles which are held between an outer, cup-shaped bristle holder and an inner, cup-shaped bristle holder.
- the outer bristle holder is welded to the fastening sleeve.
- a plate disk is arranged between the inner bristle holder and the outer bristle holder for fixing the bristles, in which edge-side bores are provided, through which the individual bristles are looped.
- This design ensures a particularly secure and durable fixation of the bristles.
- the bristle receptacles and the plate washer are held on a cylindrical carrier body and are fixed between a collar and a peripheral edge flange of the carrier body.
- the bristle receptacles are pushed together with the bristles fixed on the plate washer onto the cylindrical carrier body, which is then pressed from the outside, so that the circumferential edge flanging is created, through which a secure hold of the arrangement on the carrier body is ensured.
- 10 designates a total of an angle grinder of a conventional type.
- the angle grinder 10 has a housing 11 in which a motor shaft 12 is mounted.
- the motor shaft 12 is driven by a motor, not shown, for example an electric motor, a pneumatic motor or the like, as indicated by an arrow.
- a conical first pinion 13 is arranged in a rotationally fixed manner.
- the first pinion 13 meshes with a second pinion 14, which is also conical, so that an angular gear is formed.
- the second pinion 14 is non-rotatably connected to a hollow drive shaft 15.
- the drive shaft 15 has a non-circular inner profile 16 at its lower free end.
- a drive spindle 20 is arranged concentrically with and in the drive shaft 15.
- a non-circular section 21 of the spindle 20 is adapted to the non-circular inner profile 16 of the drive shaft 15, so that the spindle 20 is arranged in the drive shaft 15 in a rotationally fixed but axially displaceable manner.
- the spindle 20 is formed at its upper end in FIG. 1 as an elongated bolt 22.
- the bolt 22 carries a stop 23 at its upper free end.
- a disk spring assembly 24 occupies a space between the bolt 22 and the drive shaft 15.
- the plate spring assembly 24 is supported at the top by the stop 23 and at the bottom by a shoulder 25 of the drive shaft 15.
- the spindle 20 with the stop 23 is connected in the axial direction to an eccentric disk 30 via an axially movable pressure piece 26.
- the eccentric disc 30 is rotatable about an axis 31 running perpendicular to the plane of the drawing in FIG. 1.
- an elongated lever 32 which can be pivoted in the plane of the drawing in FIG. 1, as indicated by an arrow 33.
- the drive shaft 15 is axially rigid in the housing 11 in a manner not shown.
- the shoulder 25 is therefore fixed in space relative to the housing 11.
- Fig. 1 a clamping position is shown in which the plate spring assembly 24 braces the stop 23 upwards, with the result that the spindle 20 is drawn into the housing 11. This is possible because the eccentric disc 30 is in a position in which the pressure piece 26 is at a minimal distance from the axis 31.
- the arrangement is such that a fastening sleeve 41 can be plugged and fixed onto the bayonet end 40.
- the fastening sleeve 41 covers the central region of an abrasive paper 42 from the outside and presses it against a flexible one Sanding plate 43.
- the sanding plate 43 is provided on its side facing the housing 11 with a rigid disk 44 which, from the outside, bears against a radial end face of the drive shaft 15.
- the flexible grinding plate 43 has an outer region 45 with an outer, flat contact surface 46 and an inner region 47 with an outer, inner-conical contact surface 48.
- the fastening sleeve 41 has a hollow-conical section 50, the inclination of which is adapted to that of the inner-conical contact surface 48.
- a cylindrical section 51 adjoins the hollow-tapered section 50 of the fastening sleeve 41.
- the cylindrical section 51 is divided in the axial direction into a lower area 52 and an upper area 53. While the lower region 52 has a cylindrical inner surface, the upper region 53 is provided with an original opening 54, namely a triangular profile.
- the triangular profile consists of three straight sections 55 and three circular sections 56.
- the upper region 53 which is consequently narrowed over part of the circumference with respect to the lower region 52, thus has end faces 57 on the underside in the illustration in FIG. 2.
- the end faces 57 lie strictly in a radial plane.
- a peripheral collar 58 adjoins the lower region 52, which is provided with an opening 59 in its center.
- the opening 59 has, as FIG. 3 clearly shows a diameter which is smaller than the smallest radius at the three straight sections 55.
- the opening 59 is preferably designed as a cylindrical opening, but can also be conical by opening upwards in FIG. 2.
- the bayonet end 40 of the spindle 20 is divided into a first, lower bayonet section 60 and a second, upper bayonet section 61.
- the first bayonet section 60 as can clearly be seen in FIG. 6, has a larger cross-sectional area than the second bayonet section 61, so that a protrusion 62 is formed in some areas.
- an axial extension 64 can also be seen below the first bayonet section 60, which is preferably designed as a cylindrical extension.
- the shape of the extension 64 is selected so that it fits in a form-fitting manner in the opening 59 in the collar 58 of the fastening sleeve 41.
- the extension 64 forms a closure in the opening 59, which prevents dirt from penetrating into the axially behind regions of the elements forming the bayonet connection.
- the cross-sectional shape of the first bayonet section 60 is the same as the cross-sectional shape of the opening 54, apart from a slight play.
- the axial thickness of the upper region 53 also essentially corresponds to the axial thickness of the second bayonet section 61.
- the fastening sleeve 41 with the opening 54 can be pushed over the first bayonet section 60 and then rotated.
- the fastening sleeve 41 is now axially secured in the region of the straight sections 55 of the opening 54 by abutment on the projections 62.
- This bayonet connection is functional because the second bayonet section 61 has the shape shown in detail in FIG. 7 in relation to the first bayonet section 60 or the opening 54 corresponding in cross-sectional shape.
- the cross-sectional shape of the first bayonet section 60 is then divided into three arcuate sections 70, which lie on a common circumference 71 and three straight sections 72.
- the cross-sectional shape of the second bayonet section 61 is subdivided into three first straight sections 74 and three second straight sections 75 as well as three arcuate sections 76 which lie on an incircle 77 of the straight sections 72.
- the radius of the circumference 71 is R1 and the radius of the inscribed circle 77 is R2.
- the first straight sections 74 are aligned with the straight sections 72 and each take up half of their width.
- the first straight sections 74 are each adjoined at 120 ° by the second straight sections 75, the width of which corresponds to that of the first straight sections 74.
- each the arcuate sections 76 In between are each the arcuate sections 76, each of which has a circumferential angle of 60 °.
- the fastening sleeve 41 can be axially fixed on the bayonet end 40 of the spindle 20. If you now move the lever 32 against the direction of the arrow 33 from the release position to the clamping position, the fastening sleeve 41 is pulled upwards in FIG.
- the arrangement is such that the maximum eccentricity E of the eccentric disk 30 is at least as large as the axial height H2 of the inner conical contact surface 48. Because of this, in extreme cases it is even possible to do so first press the flat sandpaper 42 only slightly or not at all into the center when the fastening sleeve 41 is placed on the bayonet end 40. The eccentricity E is then sufficient to measure the entire axial path corresponding to the height H2.
- the axial length H 1 of the plate spring assembly 24 is dimensioned substantially greater than the height H 2 of the inner conical contact surface 48.
- H1 is 3 to 30 times, especially 5 times as large as H2.
- FIG. 8 Another embodiment is shown in FIG. 8.
- the angle grinder designated overall by the number 80, corresponds completely in structure and function to the angle grinder 10 described above.
- a brush-shaped grinding tool is provided in this exemplary embodiment, which is generally designated by the number 82.
- the grinding tool 82 is fastened in the manner described above to the free end of the spindle 20, which is designed as a bayonet end 40.
- a bayonet opening 91 which is provided in a fastening sleeve 81, can be plugged and fixed onto the bayonet end 40.
- the fastening sleeve 81 has a conical extension 93 on its outer end facing away from the bolt 22. This extension 93 is welded on the edge to the cup-shaped brush tool 82 via a weld 83.
- a cylindrical spacer sleeve 80 is pressed onto the fastening sleeve 41, which protrudes relative to the fastening sleeve 41 in the direction of the spindle 20 and on the end face of the Drive shaft 15 is present.
- the grinding tool 82 has bristles 84 which are held between an outer, cup-shaped bristle holder 85 and an inner, cup-shaped bristle holder 86 by means of a disk 87.
- a disk 87 In the plate disk 87, bores 90 are provided on the edge in the axial direction, through which the individual bristles 84 are passed in the manner of a loop.
- the bristle receptacles 85 and 86 and the intermediate disk 87, on which the bristles 84 are held, are fastened on a cylindrical carrier body 89.
- the cylindrical carrier body 89 is closed on its side facing the fastening sleeve 81 by a collar 92 which projects slightly outwards and against which the outer bristle receptacle 85 bears.
- the outer bristle receptacle 85 is first pushed onto the cylindrical carrier body 89 until the latter strikes the collar 92. Then the plate 87 with the bristles 84 and the inner bristle holder 86 on the Carrier body 89 pushed. The carrier body 89 is now pressed on the edge against the inner bristle holder 86, so that a circumferential flange 88 is formed, by means of which the inner bristle holder 86 is held under tension on the carrier body, so that the bristles 84 are pressed in between the two bristle holders 85, 86 and protrude outwards.
- the outer bristle receptacle 85 is welded to the conical extension 93 on the edge side.
- the bristles can be arranged so that a pot-braid brush is created.
- any other common embodiments e.g. possible as a pot brush.
- the grinding tool 82 is changed in the manner previously described with reference to FIGS. 1 to 7.
