Detailed Description
The present invention will be described in further detail in with reference to examples and drawings so that those skilled in the art can practice the invention with reference to the description.
Fig. 1 shows tool holder for a floor-working machine, which tool holder has a chisel receptacle 11 in the region of the working side and carries an insertion extension 13 directly or indirectly on the side of the insertion extension of a support body 12, the insertion extension 13 being formed by a conical body enclosing an angle, wherein the support body 12 has a -th support surface 1, a second support surface 2, a third support surface 3 and a fourth support surface 4.
As shown in fig. 2-3, the plug extension 13 is formed of a cone having a cross-sectional diameter along the central axis L of the cone (i.e., along the direction of arrow V) including, but not limited to, a diameter X (diameter at section a-a in fig. 2), a diameter Y (diameter at section B-B in fig. 2), and X > Y. The diameter X ranges in size from 40mm to 50 mm; the diameter Y ranges in size from 30mm to 40 mm. The contact surface of the plug receptacle 5 ' of the base part 20 forms a surface element line around its center axis L ' with an angle a '.
Fig. 4 shows a tool combination consisting of a base part 20 and a tool holder 10. The tool holder 10 is connected to the base part 20 in an exchangeable manner. The base part 20 has a solid base body 21 with a lower connecting side 22. The connecting side 22 is concavely curved, wherein the curvature is selected according to the outer diameter of the milling roller tube. The base part 20 can therefore be placed with its connecting side 22 on the outside of the milling roller tube and fixedly welded thereto. The base body 21 has a bulge on the front side, which bulge is delimited laterally by a ramp 23 and on the front side by a ramp 24, the ramps 24 being arranged at an angle to one another, and the ramp 23 adjoining the ramp 24 at an angle. The base part 20 is thus formed with an arrow-like geometry on the front side, which geometry gives the base part 20 a better spatial effect.
As can be seen from fig. 5, a plug receptacle 5 ' for mounting the tool holder plug extension 13 is formed in the base part 20, wherein the plug receptacle 5 ' penetrates the base part 20 completely, and a threaded receptacle 15 is formed in the base part 20 and opens into the plug receptacle 5 '.
As shown in fig. 6, in order to fix the aforementioned mounting state, the pressure bolt 16 is screwed into the threaded receiving portion 15. The pressing surface 18 presses with its flat end face against the locking surface 14 and thus produces a traction force in the direction V along the central longitudinal axis L of the plug-in extension 13. At the same time, however, the pressure bolt 16 is angled relative to the central longitudinal axis L of the plug-in extension 13 in such a way that a tensile force acting in the direction of the front side can be applied to the plug-in extension 13. This tension is transmitted via the contact surface 5 into the corresponding counter surface of the conical section of the plug receptacle 5', since the plug extension 13 is formed by a cone, the contact surface 5 forms a surface contour around the center axis L of the plug extension 13 with an angle a; the contact surface of the plug receptacle 5 'of the base part 20 forms a surface profile around its center axis L' with an angle a ', and a = a', the traction force acting in the direction of V, and the diameter X of the plug extension 13 of the tool holder 10 gradually changes in the direction of V to a diameter Y, X > Y, so that the plug extension 13 and the plug receptacle 5 'form an interference fit, and the mating surfaces of the contact surface 5 and the plug extension 5' come into increasingly tight contact due to the traction force in the direction of V generated by the compression screw 16 and the tool holder during operation, resulting in a non-rocking and reliable fixing action.
Fig. 7 to 12 show another embodiment of the present invention, and it is understood that the plug extension 13 may be formed of a tapered column, the plug extension 13 has a -th abutting surface 6, a second abutting surface 7, a third abutting surface 8, a fourth abutting surface 9, and a -th abutting surface 6 forms an angle C with the third abutting surface 8, the second abutting surface 7 forms an angle b with the fourth abutting surface 9, the length of the cross section in the direction of the central axis L (the direction of the arrow V in the drawing) includes, but is not limited to, a length e (the -th side at the section C-C), a length f (the second side at the section C-C), a length e ' (the -th side at the section D-D), a length f ' (the second side at the section D-D), and e > e ', f '. the lengths e, e ', f ' have dimensions in the ranges of 30mm-40mm, 20mm-25mm, 35mm-45mm, 25-30 mm = 30mm, 5-mm, 3-C ', 3-degrees, 3-four-degree interference fit base parts respectively.
While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to be accorded the widest scope consistent with the principles and novel features disclosed herein, as those skilled in the art will readily appreciate that many additional modifications are possible in the exemplary embodiments shown and described without departing from the -like concept defined by the appended claims and their equivalents.
