Definitions
- the invention relates to a device for holding a shaft chisel with a base part on which a chisel holder is interchangeably fastened, the chisel holder having a chisel holder for the shaft chisel, the chisel holder having a support surface on which the shaft chisel can be supported, the chisel holder being attached to the Base part is coupled by means of a pivot bearing, and wherein the bit holder rests on a counter surface of the base part by means of a contact surface.
- the base part has a recessed receptacle into which the chisel holder is inserted with a holding piece.
- the holding piece has a convexly curved contact surface.
- the counter surface of the base part is correspondingly concave. With the contact and the counter surface there is a swivel bearing. This enables the chisel holder to be mounted, whereby it is pivoted into the receptacle and slides along the contact surface on the counter surface.
- the bit holder protrudes from the receptacle with an attachment.
- This approach has a chisel holder in which a shaft chisel can be installed.
- the shank chisel is supported on an annular support surface that runs around the chisel holder.
- the forces from the shank chisel are introduced into the support surface during tool use. Starting from the support surface, the forces are then transferred into the base part via the contact surface and the counter surface.
- a curved contour of the contact surface protrudes towards the bit holder on the base part.
- This enables the support surface of the bit holder to be brought close to the contact area formed between the contact surface and the counter surface.
- the tensions in the chisel holder can be significantly reduced during use of the tool, and the service life of the chisel holder can be extended.
- the axis of rotation or the axis of rotation (hereinafter collectively referred to as "axis of rotation") of the pivot bearing intersects the bit holder of the bit holder in the assembled state of the bit holder.
- the chisel holder is moved into the volume area of the base part.
- this enables a compact design.
- the forces can be introduced directly into the base part, which leads to a noticeable reduction in tension.
- a conceivable variant of the invention is such that the base part has a recessed receptacle into which the bit holder engages with a holding section, and that the bit holder is at least partially arranged in the region of the recessed receptacle.
- the support surface for the bit holder can be arranged close to the surface of a cutting roller on which the base part is usually mounted. This means that even small cutting circle diameters can be created. This is particularly advantageous for small milling machines used in road construction.
- the tool holder has a simple design, in particular, which is also easy to manufacture if it is provided that the chisel holder has a concave joint section which cooperates with a convex joint section of the base part to form the pivot bearing.
- a compact design can also be achieved in particular if the design is such that the chisel holder has a holding section that forms the chisel holder, and that an attachment laterally to the holding section transversely to the central longitudinal axis of the chisel holder is integrally formed, which carries the joint section and that on both sides of the retaining attachment symmetrically to the central transverse plane of the chisel receptacle, an attachment is arranged, each having an articulated section, the two articulated sections forming a common joint axis.
- the tension-optimized tool design can be further improved if it is provided that the axis of rotation of the pivot bearing in the assembled state of the tool holder intersects the central longitudinal axis of the tool holder.
- a preferred variant of the invention can be such that the base part has a fastening section, by means of which it can be attached to a rotating body of a milling machine, that a connecting attachment, which carries the articulated section, adjoins the fastening section, and that the bit holder holds the connecting attachment by means of a cover on the , at least partially covers the side facing away from the fastening section.
- the cover protects the base part against wear due to the abrasive material removed during the cutting / milling process.
- a possible variant of the invention provides that the chisel holder in the assembled state rests with a seat on a stop of the base part, that the chisel holder has a fixing piece with a screw receptacle facing away from the pivot bearing, that the fixing piece is at a distance from a fastening attachment of the base part is arranged, and that the chisel holder is clamped to the fastening projection of the base part by means of a fastening screw guided through the screw receptacle.
- the spaced arrangement of the fixing piece to the pivot bearing forms a large fastening lever, which enables the bit holder to be securely attached to the base part.
- the fact that the fixing piece is spaced apart from the fastening attachment creates a clamping area. On the one hand, this compensates for dimensional tolerances. On the other hand, reliable bracing is possible.
- the base part has a receptacle in the area of the fastening attachment, in which a nut is received in a rotationally fixed manner, and that the nut is in alignment with a breakthrough of the fastening attachment and the screw receptacle of the fixing piece of the bit holder.
- the mother can also be designed as a standard mother. In the event of wear, the nut can be replaced quickly and easily.

- the fastening section 10.1 has a receptacle 1 3 in its rear area. This is open towards the bottom of the base 10 so that it is easily manufactured, e.g. B. can be milled.
- the receptacle 1 3 is designed in its cross-sectional shape so that a nut can be inserted over the open back of the receptacle 1 3.
- the circumferential contour of the nut is fixed in the receptacle 1 3 in a torsion-proof manner.
- the thread of the nut is accessible through an opening 1 4 in a fastening projection 1 5 of the base part 1 0.
- the connection approach 1 0.2 is closed with a convexly rounded front piece 1 1.
- FIG. 2 shows more clearly, two plate-shaped connecting lugs 10.2 are formed on the fastening section 10.1.
