Definitions
- the invention relates to a holder for cutting tool inserts, in particular lancing or cutting inserts, with this holding clamping slot, the opposing jaws of which have an elongated slot area, into which an expansion key with an elliptical or elongated oval cross-sectional profile can be inserted and with the opposite opening being spread apart Jaw is rotatable.
- Such holders are known for example from DE 39 06 822 C2 or EP 0 095 062 B1.
- the spreading apart of one clamping jaw relative to the other, opposite clamping jaw is brought about by inserting and turning an elliptical key in the oval-shaped region of the clamping slot.
- DE 39 06 822 C2 states that the exact geometric shape for the oval slot area is not specified in detail and, consequently, in this holder system an excessive spreading of the clamping slot, in which the yield point of the material is exceeded, is not is to be avoided with certainty.
- mountings for cutting inserts are known in the case of disc milling cutters, which are arranged in a clamping slot which has a rear extension located behind the clamped cutting insert.
- a key is provided, the first mandrel of which should engage in the extension mentioned and the second mandrel of which lies parallel to it engages on a radial end face of the disk-shaped holder.
- the disadvantage of this system is the long lever arm that is required, which leads to a high shear load on the mandrels mentioned and the risk of bending.
- a high spreading force must be applied, which can damage the holder. Controlled release of the clamping voltage is hardly possible.
- the slot-slot region has part-circular opposing extensions, the apexes of which have a distance which is smaller than the greatest distance of the elliptical or elongated oval cross-sectional profile.
- Such extensions can be created by drilling the elongated slot area.
- the advantage over elongated oval extensions with flat or those interfaces whose radius of curvature increases lent is greater than the effective radius of the expansion key, there is much better guidance of the expansion key. In terms of production technology, such extensions are easier to manufacture than oval or oblong extensions.
- the intersection points at which the circular extension in each case merges into the adjacent elongated slot areas represent the only contact points in the form of a 4-point support. This has the effect that the expansion key already during insertion with regard to its position receives a clearly defined position. When actuated by turning, the spreading forces act evenly on opposite surface sections due to the 4-point support.
- the distance between the jaws of the unspread slot area outside the extensions is smaller than the larger semi-axis but larger than the small semi-axis of the elliptical cross-sectional profile or smaller than the maximum distance between two opposite boundary points of an elongated oval cross-sectional profile.
- the part-circular extensions are preferably arranged axially asymmetrically with respect to the elongated hole longitudinal axis, and further preferably such that the lower extension is larger than the upper one.
- the cross-sectional profile of the expansion key essentially consists of a rectangular profile, on the short sides of which are segment-shaped protuberances. This dimensioning ensures one clear guidance of the expansion key in the area of the circular extensions.
- the cross-sectional profile jacket is edge-free or has only four edges, on which the short sides adjoin the long sides.
- the radius of the circular segment-shaped protuberances of the short sides of the expansion key is larger than the radius of the circular extensions of the elongated slot area. This measure allows a favorable compromise between optimal guidance and the least possible friction when spreading, i.e. Turning the expansion key.
- the distance between the vertices of the opposite circular extensions is greater than the diameter of the circular extensions of the elongated slot area.
- one of the jaws has a projecting stop for limiting the insertion for the cutting insert, the circular extensions between this stop and the end of the slot region, preferably being as close as possible to the stop. Due to the correspondingly long configuration of the slot area, an optimal elasticity of the clamping jaws can be guaranteed.
- FIG. 1 shows a side view of a holder with the cutting insert inserted
- Fig. 2a shows a socket wrench in a side view
- Fig. 2b is a sectional view along the line
- the holder 10 shown in each case has a clamping slot for holding a cutting insert 11, in the rear clamping slot extension 12 in the region of an extension to an elongated hole 25 part-circular extensions 13 and 14 are provided, the vertices of which have a spacing e which is at the apex is smaller than the largest distance a of the elliptical or elongated oval cross-sectional profile 15.
- This cross-sectional profile is part of a plug-in connector 16 and can be inserted so loosely that the four points at which the circular extensions 13 and 14 each merge into the elongated slot area 25 are the only points of contact 17 to 20 in the form of a 4-point - represent editions.
- the clamping arm 22 can be spread out by turning the key 16 by a maximum of 90 °.
- the slot area 12, 25, 21 is a rear continuation of the clamping slot in which the cutting insert 11 is clamped.
- the upper clamping jaw 22 also has a stop 24 as a rear boundary.
- the circular extensions 13 and 14 are relatively close to the stop 24, at least at a considerable distance from the circular rear extension 23. A sufficient lever arm is thus available for spreading, the length of which is determined by the spacings of the extensions 13 and 14 from the end region 23.
