- the present invention relates to a tool for machining for drilling or milling with a rotatable about a tool axis tool body and a fastened to the tool body holding member with a cutting board seat for a cutting plate.
- a tool is known for example from DE 103 15 394 A1.
- This boring tool has a drive shaft and serves, for example, for widening a pre-machined bore.
- the tool rotates about a central axis, also called tool axis or drilling axis, which is substantially perpendicular to the end face of the tool body.
- tool axis also called tool axis or drilling axis
- the cutting plates received on the retaining element engage with the inner contour of the bore, expand it and, if necessary, carry out the finishing of the inner surfaces.
- the diameter of the drill can be varied by moving the retaining elements in the radial direction, i. perpendicular to the tool axis, can be moved to a limited extent.
- this object is achieved in that an adjusting device is provided for the axial adjustment of the holding element with respect to the tool body.
- the invention proposes to adjust the holding element together with the cutting board seat and thus together with the cutting plate axially and not just the cutting plate.
- a slider body could be provided, which is fastened to the tool body and in the radial direction relative to the tool body between two positions back and forth movable, wherein the holding member is attachable to the slider body.
- the slider body is initially set in the radial direction relative to the tool body and then set the holding member relative to the slider body in the axial direction.
- the adjusting device preferably has an adjusting screw, which is arranged in a first threaded bore in the tool body or in the slider body and optionally applied via a contact piece on a contact surface of the support member, so that when turning the adjusting screw in the threaded bore, the holding member axially against the slider body or the tool body is moved.
- the first threaded hole with the tool axis includes an angle between 15 ° and 165 °, preferably between 45 ° and 135 °, more preferably between 60 ° and 120 °, and most preferably about 90 °.
- the contact surface of the holding element or a corresponding with the contact surface of the holding element engaging stop surface of the adjusting screw or the investment piece preferably closes with the first threaded hole an angle between 0 ° and 90 °, more preferably between 0 ° and 20 ° and more preferably between 10 ° and 20 °.
- a spring element may be provided, which biases the holding element in a specific axial position.
- the holding element has a second threaded bore and the slider body or the tool body has a through hole, so that the holding element can be fixed with a through the through hole in the second threaded hole engaging locking screw on the slider body or on the tool body.
- the through hole is formed as a slot.
- the retaining element has a web-shaped projection and the slider body or the tool base body has a corresponding groove, the second threaded bore preferably being arranged in the web-shaped projection and the through-hole being arranged in the groove.
- a stop surface for the locking screw head can be provided on the slider body or on the tool body, wherein the stop surface with the groove bottom an angle of> 0 °, preferably between 1 ° and 20 ° and particularly preferably between 1 ° and 10 ° includes.
- the second threaded hole in a preferred embodiment with the radial direction at an angle between 15 ° and 165 °, preferably between 45 ° and 135 ° and more preferably between 40 ° and 50 °.
- an extension arm is provided which is fastened on the one hand to the tool base body and on the other hand carries the cutting plate holder, wherein the cutting plate holder can be fastened to the extension arm at at least two positions spaced apart from one another in the radial direction.
- FIG. 1 shows a perspective view of an embodiment of the invention
- FIG. 2 shows a side view of the embodiment of FIG. 1
- FIG. 3 shows a further perspective view of the embodiment of FIG. 1,
- FIG. 4 shows a view from below of the embodiment of FIG. 1,
- FIG. 5 shows a plan view of a slider body, - -
- FIG. 6 shows a side view of the slider body of FIG. 5
- Figure 7 is a sectional view taken along the line A-A in Figure 6 and
- FIG. 8 is a sectional view taken along the line B-B of FIG. 5.
- FIG. 1 shows a perspective view of an embodiment of the invention.
- a boring tool 1 has a tool base 2, which has an interface 3 to a corresponding drive.
- the interface 3 consists here of a steeply tapered shaft 3, on whose end facing the tool base body a gripping groove 4 and a flange 5 are arranged for a- xialen support.
- the interface can also be designed as a separate component that can be connected to the tool base body 2.
- the interface expediently has an axially over the flange 5 projecting centering pin (not shown), which can engage in a corresponding central bore (not shown) in the tool body.
- the tool base body here has a wheel-shaped section 6, which is connected to an inner hub section via corresponding spoke sections 7. At the tool body 2 and at the spoke portions 7 extension arms 8 are attached.
- the embodiment shown has four spoke sections 7, to each of which an extension arm 8 is attached.
- an insert holder 9 is accommodated, which has a web-like projection 10 which lies in a groove 11 of the extension arm 8.
- Figure 2 shows a side view of the embodiment of Figure 1. It can be seen here that the insert holder 9 has a seat for a cutting plate 12 which is held by means of a clamp 13 on the cutting board holder.
- the web-like projection 10 is slightly inclined, resulting in better axial contact during operation.
- the screw 14, which is arranged within the web-like projection 10, serves for the radial displacement of the insert holder 9 within the groove 11 of the extension arm 8.
- Figure 3 is a perspective view from below and in Figure 4 is a plan view from below of the embodiment of Figures 1 and 2 is shown.
- the tool body 2 consists of an inner hub portion, a wheel-shaped portion 6 and four spoke sections 7.
- the extension arms 8 are screwed onto the spoke sections 7.
- the insert holder 9, which in turn consists of a slider body 15 and a holding element 16 received therein, which comprises the cutting plate seat, has at least one elongated hole, in the example shown, three elongated holes 17 can be seen.
- the extension arm 8 has a corresponding number of threaded holes 18, so that the insert holder 9 due - -
- the slots 17 can be adjusted in the radial direction. This is done, as already mentioned, with the aid of the adjusting screw 14 (see Figure 2).
- extension arm 8 has a second set of threaded holes 18.
- the insert holder 9 can therefore be completely detached from the extension arm 8 and be re-attached by means of the additional threaded holes at a radially spaced position. Even in the new position allow the slots 17 a certain radial displacement of the insert holder relative to the extension arms. 8
- the tip holder can be displaced relative to the extension arm, but it is also possible to use a different shaped extension arm 8 or a differently shaped tool body 2. Furthermore, it is possible to use tool body with a different number of spoke sections. In addition, it is not absolutely necessary that the individual spoke sections are arranged equidistantly in the circumferential direction. On the contrary, in a so-called differential division has been found that vibrations that might occur in operation, can be minimized.
- FIG. 5 shows a plan view of a slider body 15.
- the slider body 15 forms together with the support member 16, the cutting plate holder 9.
- the slider body 15 has on its underside a web-like projection 10 which can be inserted into a groove 11 of the extension arm 8.
- To fasten the slider body 15 on the extension arm 8 serve three screws which engage in corresponding threaded holes of the extension arm. They engage in the attachment through corresponding slots 17 of the slider body 15, so that when the screws are released, the slider body 15 can be moved radially between two positions back and forth. Once the slider body 15 is in the desired position, it can be secured to the extension arm 8 by means of the screws.
- the holding element 16 has a clamp 13 with which the cutting plate 12 can be held in the holding element 16.
- the slider body 15 has a groove 28 in which a corresponding web 27 of the retaining element 16 engages. For fixing the retaining element 16 in the groove 28, a fastening screw 29 is used.
- FIG. 8 which shows a sectional view along the line BB
- the fastening screw 29 in the slider body 15 has some play.
- the angle ⁇ shown in Figure 8 between the groove bottom of the groove 28 and the contact surface for the head of the fastening screw 29 is preferably> 0 ° and is best in the range between 0 ° and 10 °.
- Figure 7 shows a sectional view along the line AA of Figure 6. It can be seen that the holding member 16 has on its underside a chamfer 33 and a V-shaped recess.
- the slider body 15 has a spring element 30, which is designed as a resilient pressure piece, which projects under spring action into the recess provided for the retaining element 16.
- a piece of equipment designed as a wedge 31 is fastened to the slider body 15 with the aid of an adjustment screw 32.
- the holding element 16 When inserting the holding element 16 in the groove 28 of the slider body 15, the holding element 16 is inserted in Figure 7 from bottom to top in the slider body 15.
- the resilient pressure piece 30 will engage the chamfer 33.
- the resilient pressure member 30 By the chamfer 33, the resilient pressure member 30 is pressed into the slider body 15 (in the figure 7 to the left) until the V-shaped recess with respect to the pressure piece 30 comes to rest.
- the holding member 16 abuts on the wedge 31.
- the wedge 31 With the help of the adjusting screw 32, the wedge 31 can be moved, whereby an axial adjustment of the holding element 16 takes place. By the wedge 31 a finer adjustment is possible.
- the spring element 30 is essentially to push the retaining element 16 along the groove 28 in the direction of the wedge 31 when the wedge 31 is reset. As soon as the axial position of the retaining element is reached, the retaining element 16 can be fixed on the slider body 15 with the aid of the fastening screw 29.
