Definitions
- the present invention relates to a bit holder comprising a body portion having a bit receiving opening open at least to a bit insertion side of the body portion and a fastener shaft having a shaft longitudinal axis extending from a support side of the body portion, the body portion having a first support surface portion on its support side.
- Such a bit holder for a road milling machine or the like is known from DE 43 22 401 C2.
- the chisel receiving opening of this known chisel holder is open at its end remote from the chisel insertion side, ie at the support side, to the first support surface area.
- the attachment shaft extends from the body portion.
- the first abutment surface area of the chisel holder rests on the first counter-abutment area of the base part, so that in principle a defined positioning of the chisel holder is predetermined on the base part.
- a clearance is provided between the attachment shaft bearing portion of the body portion and the opposite side of the base member to provide a so-called bit holder retention space allowing deeper penetration of the attachment shaft into the attachment shaft receiving aperture when in the region of the first support surface region. and the first counter-Abstütz vom Kunststoff Kunststoffs wear occurs.
- first support surface region and thus also the first counter-support surface region are approximately orthogonal to a chisel receiving opening longitudinal axis and thus also a longitudinal axis of the bit, transverse loads can arise in the milling operation, which leads to a considerable amount of torsion when the attachment shaft adjoins the body region. as well as shear stress, which can also lead to a demolition of the fastening shaft in unfavorable cases when designing the fastening shaft with a comparatively large shaft cross-sectional area.
- a bit holder comprising a body portion having a bit receiving opening open at least to a bit insertion side of the body portion and a fastener shaft having a shaft longitudinal axis extending from a support side of the body portion, the body portion having a first support surface portion at its support side.
- the body region has on its support side a second support surface region angled with respect to the first support surface region and / or that the first support surface region comprises a first support surface and a second support surface angled relative to the first support surface.
- the bit receiving opening is substantially open
- the first supporting surface area also has two supporting surfaces which are angled relative to one another, a total of four supporting surfaces which are pyramid-like angled, in particular a funnel-like configuration, are provided on the bit holder which avoids or at least reduces the introduction of force into the securing shaft and consequently a considerable reduction the burden of the same brings in particular transversely to its shaft longitudinal axis with it.
- the first support surface and the second support surface of the first support surface region and / or the second support surface region are arranged substantially symmetrically with respect to a holder center plane.
- the holder center plane essentially represent the geometric center of the chisel holder can and can be clamped, for example, by the shaft longitudinal axis and a longitudinal axis of the chisel receiving opening.
- a first angle enclosed between the first support surface and / or the second support surface of the first support surface region and the second support surface region is in the range of 127 ° to 147 °, preferably approximately 137 ° and / or a second angle enclosed between the first support surface and the second support surface of the first support surface is in the range of 120 ° to 140 °, preferably about 130 °, and / or between the first support surface and the second support surface of the first support surface second support surface area included third angle in the range of 100 ° to 120 °, preferably at about 1 10 °, and / or between a transition region between the first support surface and the second support surface of the first support surface region and a transition region between the first support surface and un d of the second support surface of the second support surface area included angle in the range of 121 ° to 141 °, preferably at about 131 °.
- the various support surfaces of the chisel holder constructed according to the invention are substantially planar, ie not curved, it is proposed to allow a direct transition of such support surfaces into each other that at least one support surface of the first support surface region and the second support surface region in a line-like and / or Just adjoin the first transition area to each other.
- the first support surface and the second support surface of the second support surface region adjoin one another in a planar or / and straight extending second transition region. It has been shown that, in particular in the manufacture of ment of the chisel holder as a forging in the transition region between the two support surfaces of the first support surface area an approximately flat, area-like area arises, which can be processed in a simple manufacturing technology to a planar or straight extending second transition region.
- the second transition region comprises a transition surface substantially orthogonal to the holder center plane.
- a longitudinal center axis of the bit receiving opening and the shaft longitudinal axis at an angle of 10 ° to 15 °, preferably about 12.5 °, are inclined to each other.
- This angle has therefore proved to be particularly advantageous, since it has been found that in milling operation, the forces acting on a bit are generally not parallel to its longitudinal axis and thus not inclined in the direction of the longitudinal axis of the bit receiving opening, but slightly inclined thereto. This inclination can be taken account of by the employment of the shaft longitudinal axis with respect to the longitudinal axis of the chisel receiving opening.
- the attachment member loading area may comprise an attachment member engagement surface, and the shaft longitudinal axis and a surface normal of the attachment member engagement surface may be inclined to each other at an angle of 50 ° to 65 °, preferably about 62.5 °.
- a force exerted approximately in the direction of this surface normal on the fastening element contact surface by means of a fastening element is inclined as little as possible to the longitudinal axis of the shaft, thus loading it as strongly as possible in the direction of its longitudinal axis ,
- This also cross-loads can be reduced in the shaft, however, such a Orientation of a trained example as a bolt fastener to be ensured that when used in a base part tool holder access to the attachment member.
- the object mentioned at the outset is achieved by a bit holder system, comprising a bit holder preferably constructed according to the invention and a base part with a first counter-support surface region for supporting the first supporting surface.
- This bit holder system is characterized by a second counter-support surface area angled relative to the first counter-support surface area for supporting the second support surface area, and / or in that the first counter-support surface area comprises a first counter-support surface for supporting the first support surface of the first support surface area and a second counter-support surface, angled relative to the first counter-support surface, for supporting the second support surface of the first support surface region.
- provision may be made for the angling of the first support surface area with respect to the second support surface area and the angling of the first counter support surface area with respect to the second counter support area and / or the angling of the first support surface with respect to the second support surface of the first support area and the angling the first counter-support surface with respect to the second counter-support surface of the first counter-Abstütz vom Kunststoff Scenes are complementary to each other.
- the second counter-support surface region has a first counter-support surface for supporting the first support surface of the second support surface region and a second counter-support surface angled relative to the first counter-support surface for supporting the second support surface of the second support surface area.
- provision can be made for the angling of the first support surface with respect to the second support surface of the second support surface region and the angling of the first counter-support surface relative to the second counter-support surface of the second counter support surface region are complementary to each other.
- the first counter-support surface and the second counter-support surface of at least one counter-support surface region adjoin one another in a countersink-type third transition region. Since, as in the case of the various support surfaces, the various counter-support surfaces are also advantageously provided with a substantially planar, ie non-curved, configuration, the provision of a depression-type transition region between such counter-support surfaces results in notch stresses under heavy load avoided.
- a volume is kept free, into which a transition region extending, for example, in a straight line between two support surfaces of a support surface area or two support surface regions can dip without abutting the tool holder and base part in this region.
- further volume is kept ready to allow for the occurrence of wear at least a slight resetting of the bit holder.
- first counter-support surface region and the second counter-support surface region in connect a Einsenkungsartigen fourth transition area together.

- a bit receiving aperture 18 is provided therethrough or the entire body portion 12. This is open at the bit insertion side 14 for receiving an exchangeable chisel lockable therein by a friction lock seat, and is open at a support side 20 of the body portion 12 substantially opposite to the bit insertion side 14. From this side, a tool inserted to remove a worn bit from the bit receiving opening 18 may be inserted to force the bit out of the bit hole 18.

- the second support surface area 24 also comprises a first support surface 32 and a second support surface 34.
- the two support surfaces 32 , 34 are angled to each other and thus also angled to the holder center plane, in which case the embodiment with respect to the holder center plane corresponding to the configuration of the two support surfaces 28, 30 of the first support surface area 22 may be symmetrical.
- first transition regions 36 38 are formed on an edge-like adjoining region of the respective support surfaces. Due to the fact that the support surfaces 28, 30, 32, 34 are preferably all flat, that is, not curved, these are thus also line-like first transition regions 36, 38 according to uncrimped.
- a second transition region 40 formed between the first support surface 32 and the second support surface 34 of the second support surface region 24 is formed with a substantially straight transition surface 42. This is essentially orthogonal to the holder center plane. Since the two support surfaces 32, 34 are substantially planar, that is to say unconstrained, this second transition region 40 also extends substantially rectilinearly.
- an angle Wi is formed, which is in the range of about 137 °.
- An angle W 2 of approximately 130 ° is formed between the two support surfaces 28, 30 of the first support surface region 22, so that each of these support surfaces 28, 30 has an inclination angle of approximately 65 ° to the holder center plane.

- the angle W 4 are in the range of 67 °, while the angle W 5 may be about 64 °. It should be pointed out here that in order to determine these angles W 4 or W 5, a line connecting the respective support surfaces 28, 30 or 32, 34 in the case of imaginary extension thereof can be used or, in the case of the support surfaces 32, 34, the angle W.
- the total angle formed by the sum of the two angles W 4 and W 5 can therefore be in a range of approximately 131 ° and defines the angle of attack of two prism-like configurations, one of which is defined by the two support surfaces 28, 30 of the first support region 22 and the other is defined 24 by the two support surfaces 32, 34 of the second Abstütz vom Kunststoffs by varying this Ambiwin- kels, ie the sum of the two angles W 4 and W 5, wherein, for example, kept equal angles thus the geometry W 2 and W 3 of the pyramid-like arrangement, formed by the four support surfaces 28, 30, 32, 34, and in particular a concentration of the forces in the direction of an imaginary pyramid vertex are supported.
- FIGS. 11 and 12 show this base part 44 in assembly with the bit holder 10.
- a fastening shaft receiving opening 46 is formed, which can be seen both at a counter-support side 48, which can be seen at the top in FIG. 9, and at a recognizable one in FIG Connecting side 50 of the base 44 is open.

- a first counter-support surface region 52 is formed in association with the first support surface region 22.
- a second counter-support surface region 54 is formed in association with the first counter-support surface region 52.
- the first counter-support surface region 52 comprises a first counter-support surface 56 in association with the first support surface 28 of the first support surface region 22 and comprises a second counter-support surface 58 in association with the second support surface 30 of the first support surface region 22.

- the respective counter-Abstützflä- surfaces 56, 58, 60, 62 are mutually angled in accordance with the respective Anwinkelungen the support surfaces 28, 30, 32, 34 of the bit holder 10 to each other and flat, so that the mutually associated support surfaces and counter-support surfaces can abut each other flat.
- an immersion-type third transition region 64 or 66 is formed between the two counter-support surface regions 52, 54, ie between the first counter-support surface 56 and the first counter-Abstützflä- 60 and the second counter-support surface 58 and the second counter-support surface 62.
- a depression-like fourth transition region 68, 70 is formed between the two counter-support surface regions 52, 54, ie between the first counter-support surface 56 and the first counter-Abstützflä- 60 and the second counter-support surface 58 and the second counter-support surface 62.
- the recess-like transitional regions 64, 66, 68, 76 are each provided with space for the various transition regions of the bit holder 10, where the support surfaces thereof merge into one another. This ensures that even if wear occurs in the region of the abutting support surfaces or counter-support surfaces, a re-setting and, accordingly, a deeper penetration of the first and second transition regions in the third and fourth transition regions is possible.
- the support side 20 formed on the bit holder 10 on the one hand and the counter-support side 48 formed on the base part 44 on the other hand complement each other in particular with the support surfaces or counter-support surfaces coming into abutment with each other are shaped.
- a plurality of prism-like adjoining support surfaces or counter-support surfaces results in a funnel-like configuration which ensures stable support of the bit holder 10 and base part 44 also in the direction transverse to the attachment shaft 26 or the shaft longitudinal axis L B.
- the attachment shank 26 of the chisel holder 10 has an attachment member application area 76 at a first side located approximately below the first support surface area 22 and has a support area 78 at a second side opposite the shank longitudinal axis L B.
- the Befest onlysorganbeetzungs #2 is notched like formed with a Befest onlysorganbeetzungs simulation 80, the surface normal F N with respect to the shaft longitudinal axis L B at a relatively small angle W 7 of about 62.5 ° is inclined.
- a fastening element 82 provided on the base part whose longitudinal center axis is oriented approximately parallel to the surface normal F N , ie substantially orthogonal to the fastening member loading surface 80, acts comparatively strongly in the direction of the shaft longitudinal axis L B when the fastening shaft 26 is acted upon directed force component generated.
- the fastening member 82 is received in a mounting member receiving opening 84 of the base member 44 which is at least partially formed with internal thread, so that at least partially formed with external thread attachment member 82 by rotation, so screwing in the direction of Befest Trentsorganryö Maschinenslticiansach- se l_o can be moved toward the Befest onlyoorganbeetzhausungs composition 80 to and away from it.
- the fastening member receiving opening longitudinal axis L 0 stands for a fastening shank receiving opening longitudinal axis L A , which, in the assembled state, also substantially coincides with the shank longitudinal axis L B , at an angle W 7 of approximately 62.5 °.
- the support region 78 is formed with two support surface regions 88, 90, which run angled or inclined with respect to each other, in particular each have a preferably circularly curved course in the circumferential direction about the shaft longitudinal axis L B. In a central region of the support region 78, these two support surface regions 88, 90 adjoin one another in a fifth transition region 92.
- This fifth transition region 92 is formed like a depression, preferably with in the direction of the shaft longitudinal axis L B extending, concave depression profile.
- the support surface regions 88, 90 of the support region 78 are formed such that they project at least in regions beyond a base outer peripheral surface 94 of the attachment shaft 26 radially with respect to the attachment shank longitudinal axis L B.
- the design is such that this radial projection in the central region of the support region 78, ie where the fifth transition region 92 is formed, is the lowest, so that there is almost no radial projection, for example, while in the circumferential direction and in the direction from the fifth transition region 92, this radial projection increases.
- a further significant advantage of the support surface regions 88, 90 projecting radially beyond the base outer peripheral surface 94 is that locally localized surface regions are used there to generate abutting contact between the attachment shaft 26, ie the bit holder 10, and the base part 44. Since both the bit holder 10 and the base member 44 are generally provided as forgings and thus those surfaces in which a mutual support, to achieve the required precision material to be edited or reworked, this operation can be limited to the For actually provided surface areas, namely where the support surface areas 88, 90 are formed.
- the counter-support region 86 is formed on the base part 44.
- the counter-Abstützbe- rich 86 in association with the support surface areas 88, 90 counter-support surface areas 96, 98.
- These adjoin one another in a sixth transition region 100, wherein the sixth transition region 100 is formed as a projection, preferably with a convexly curved projection 102 elongated in the direction of the fastening shaft receiving opening longitudinal axis L A.
- This projection can be provided by an insert 104 for production-related reasons which is inserted into a corresponding opening 106 of the base member, for example, press-fitting and projects with a peripheral portion thereof for providing the projection 102 radially inward beyond the two counter-supporting surface portions 96, 98.
- the counter-Abstützbericht Schemee 96, 98 are formed in the Befest whysschaftareaö réelle 46 such that they project at least partially over a basic inner peripheral surface 108 of the Befestriensschafta- opening 46 radially inwardly with respect to the Befestriensschaftareaöffungs- longitudinal axis L A.
- the configuration may be such that near the sixth transition region 100, this radial projection is maximum and decreases in the circumferential direction in the direction away from the sixth transition region 100, so that gradually the counter-Abstützflä- surfaces 96, 98 pass into the basic inner peripheral surface 108.
- a restriction of the surface areas to be machined to provide a precise abutment contact on the counter Abstützbericht Kunststoffe 96, 98 is reached, in particular in their two axial end portions again like a step or curvature in the base inner peripheral surface 108 on the base part 44 can pass.
- the two counter-support surface regions 96, 98 are inclined with respect to each other, in this case with a curved course, this curvature being able to correspond to the curvature of the two support surface regions 88, 90 in order to achieve a large contact area.
- the attachment shaft 26 can in principle be inserted into the fastening shaft receiving opening 46 with lateral play , wherein only by the movement of the fastening member 82 on the Befest Trentsorganbeetzungs solution 80 to a fixed abutting contact between the Abstütz vomauer Societyen 88, 90 and the counter-Abstützbericht Kunststoffen 96, 98 is generated. A leading to a stronger pressure contact of the two transition regions 92, 100 is thereby avoided.
- both the support portion 78, and the counter-support portion 86 to the holder center plane or a plane corresponding to this symmetry plane of the base member 44 symmetrical, in particular point-symmetrical, are formed.
- the support region 78 and the counter-support region 86 constructed in accordance with the principles of the present invention can also be constructed in such a way that the support region 78 is basically formed on the outer peripheral surface of the support Attachment 26 is provided without a board on the base outer peripheral surface 94, so provided, for example, provided with approximately circular peripheral contour base outer circumferential surface 94 and the support surface areas 88, 90 on both sides of the einproofungsungsform trained transition region 92.
- This recess-like transition region 92 can in this embodiment, but basically also in the embodiment with respect to the base outer peripheral surface 94 radially projecting Abstweilbericht Schemeen 88, 90, for example, be designed as a substantially planar transition surface between the Abstützbericht Schemeen in the circumferential direction on both sides, ie a surface which is recessed radially inward with respect to a circumferential contour defined by the outer periphery of the attachment shaft 26.
- a substantially planar configuration obtained, for example, by material-removing machining or else in the casting process, is particularly advantageous due to the ease of manufacture. In principle, however, could also be a respect to the curvature of the mounting shaft 26 slightly flattened curved transition surface in the transition region 92nd be provided.
- a corresponding geometry can also be provided on the counter-support region 86 in the base part 44.
- the counter-support surface regions 96, 98 can be integrated into the base inner circumferential surface 108, and therefore do not necessarily have to protrude radially inward relative thereto.
- the transition region 100 between the two counter-support surface regions 96, 98 can then also be designed as a substantially planar transition surface, for example, of the correspondingly shaped transition surface of the transition region 92 then to be positioned opposite. In the case of such a configuration, as can also be seen in FIGS.
- the support region 78 may be provided on the axially free end region of the attachment shaft 26, so that starting from a substantially circular peripheral contour of the base outer peripheral surface 94 Then also the support surface areas 88, 90 provides, in the axially free end region of the mounting shaft 26 then, for example, a substantially flat, radially inwardly with respect to the generally existing circular peripheral contour einlenkungsartig recessed transition region 92 is present.
- a supporting surface area or counter-supporting surface area with the respective surfaces serving for mutual support is designed or processed in such a way that a direct metal-metal contact contact can be produced. Since both the base part and the chisel holder are generally produced as forgings, the surfaces serving as support surface areas or counter-support surface areas in the context of the present invention are thus basically manufactured and / or reworked in terms of materials. In this way, the high precision required for a substantial relief and accurate positioning of these surfaces can be ensured, which would not be feasible in a merely machined in a forging surface.
- the bit holder 10 with its attachment shank 26 is inserted into the stub shaft 10 provided in the base member 44 Befest Trentsschaftaidö réelle 46 at on a rotatable milling drum fixed by welding, until the two Abstweilberichtbericht Schemee 22, 24 of the bit holder 10 in contact with the respective associated counter-Abstweilbericht Schemeen 52, 54 of the base part come. Then, for example, the screw-type fastening member 82 is tightened so that it is further moved into the fastening organ receiving opening 84 and is pressed against the fastening member loading surface 80 on the fastening shaft 26.
