Definitions
- the invention relates to a bit holder changing system for a road milling machine, a cutting machine or the like with a base part to which a bit holder is exchangeably fastened by means of a connecting mechanism, the bit holder interchangeably receiving at least one bit, the central longitudinal axis of the bit being smaller than the working surface in the working angle is set as 90 °.
- the bit holder changing system has a base part, which protrudes welded onto a surface of a roller body.
- the base part has a plug-in receptacle into which a plug insert of the chisel holder can be inserted.
- the chisel holder is provided with a mounting hole into which a chisel shank of a round shank chisel is inserted.
- the chisel holder can be clamped to the base part using a fastening screw.
- the central longitudinal axis (axis of rotation) of the round shank bit is inclined with respect to the surface to be machined.
- This object is achieved in that the chisel holder can be fixed to the base part in two or more attachment positions, and in that the central longitudinal axis of the chisel is inclined by different working angles in the different attachment positions.
- the chisel holder is supported on a contact surface of the base part by means of a support surface, and that the chisel holder can be displaced relative to the contact surface on its support surface in order to achieve the different mounting positions.
- the bit holder can be adjusted with respect to the base part.
- certain, preferably used, working angles are assigned to the individual grid points. In the case of a road milling machine, these are, for example, the angles 35 °, 40 ° and 45 °.
- the rasterized adjustment can be achieved, for example, in that the chisel holder is provided with a toothing that is in engagement with a counter-toothing of the base part, that the toothing and the counter-toothing have flat support flanks that extend transversely to the direction of adjustment of the bit holder relative to the base part.
- the forces occurring during operation can be safely diverted into the base part via the support flanks.
- the tool holder changing system is usually applied to a roller-shaped base body which can be moved about an axis of rotation.
- a tool holder changing system is characterized in that the counter-toothing of the base part has two partial teeth and that the partial teeth for absorbing transverse forces in the direction transverse to the feed direction of the bit are inclined.
- An alternative design variant of a bit holder change system can be realized, for example, in that the base part has a contact part which is equipped with a plurality of concentrically arranged tooth elements of the counter-toothing, that the bit holder carries a clamping plate which is provided with a toothing adapted to the counter-toothing, and that the bit holder is rotatable relative to the base part about an adjustment axis which is arranged transversely to the direction of advance of the bit.
- Such a connection mechanism can also be designed as a Hirth tooth system. Due to the large number of tooth elements, extremely high forces can be transmitted via this connection mechanism.
- the chisel holder has a base body which carries a holding attachment for receiving the chisel that the base body has an elongated hole which is aligned with a threaded receptacle of the base part, that a fastening screw can be inserted into the elongated hole and screwed into the threaded receptacle, and that the bit holder is adjustable when the fastening screw is loosened.
- the screw head of the fastening screw should be protected in a recess that widens after the elongated hole. A particularly good and firm bracing of the screw head with the chisel holder can be achieved if the screw head is designed as a lens screw head.
- the chisel holder In the event of wear or in the case of impermissibly high loads, it can happen that a bit holder is damaged.
- the chisel holder carries a holding attachment on a base body, that the holding attachment has a receiving bore for a chisel shaft of the chisel, and that the holding attachment with the base body over a predetermined breaking point is connected.
- FIG. 1A and 1B show a tool holder changing system in two views and in a first setting position
- Fig. 4 shows an embodiment variant of a base part for a
- FIG. 5 in side view a further embodiment variant of a tool holder changing system.
- 1 shows a tool holder changing system which has a base part 40 and a tool holder 20.
- the base part 40 has a lower connection surface 41 with which it can be placed on a cylindrical base body, for example a road milling machine.
- the connection to the cylindrical base body is made by means of weld seams.
- the base part 40 On its side facing upward, the base part 40 is provided with an arcuate contact surface.
- the contact surface has counter teeth 42.
- the individual teeth of this counter-toothing 42 are triangular in cross-section and thus form two contact flanks.
- the teeth of the counter toothing 42 extend over the entire width of the base part 40.
- a thread receiver 43 is incorporated into the contact surface of the base part 40 over half the width of the teeth.
- the thread receptacle is arranged so that it is incorporated into the base part to take up as much space as possible and thereby provides a sufficient thread length for a fastening screw.
- the thread receptacle 43 is therefore introduced obliquely into the contact surface.
- a low overall height of the base part 40 can also be achieved. This has particular advantages, since the entire structure of the bit holder changing system can therefore be kept small.
- the chisel holder 20 can be attached to the base part 40.
- the chisel holder 20 has a base body 25 which is provided with an elongated hole 28.
- the elongated hole 28 widens towards the outside of the base body 25 by means of a recess 27.
- the fastening screw which in the present case represents the connecting mechanism 30, can be inserted through the elongated hole 28 and screwed into the threaded receptacle 43.
- the screw head 32 is then protected in the recess 27. When the fastening screw is tightened, the screw head 32 is in the transition area between
- Chisel holder 20 can be pressed against the base part 40 and over which large forces can be transmitted during work.
- the base body 25 has a protruding retaining lug 21, into which a receiving bore 22 is machined.
- the central longitudinal axis of the receiving bore 27 is at right angles to the arcuate contact surface of the base part 40.
- An expulsion channel 23 is drilled into the tool holder 20 from the rear of the tool holder changing system.
- the drive-out channel 23 crosses the receiving bore 22.
- a chisel 10 can be inserted into the receiving bore 22.
- the chisel 10 has a chisel head 17 which carries a chisel tip 11.
- the chisel tip 1 1 is designed as a hard metal element.
- a chisel shaft adjoins the chisel head 17, on which a clamping sleeve 12 is fitted.
- the clamping sleeve 12 is spread out in the receiving bore 22. At the same time, the clamping sleeve 12 holds the chisel shaft of the chisel 10 and thus prevents it from falling out. In the inserted state, the chisel head 17 rests on a wear protection disk 14. The wear protection disc 14 is supported around the receiving bore 22 on the bit holder 20. The chisel 10 can be pulled out of the receiving bore 22 in two different ways. On the one hand, an expulsion mandrel can be inserted into the expulsion channel 23 through an inlet opening 24 until it comes to rest on an end face 13 of the chisel shaft.
- the chisel shank can then be driven out of the receiving bore 22 with a hammer blow. Furthermore, a circumferential extraction groove 15 is introduced into the chisel head 17, into which an extraction tool can be inserted.
- the chisel 10 can then be levered out of the receiving bore 22 by means of a lever.
- 1 A and 1 B show that the fastening screw is arranged centrally in the slot 28. This results in a working angle a at which the central longitudinal axis 16 of the chisel 10 is set in relation to the surface to be machined.
- the complementary angle is shown in FIG. 1A with a '. If this working angle a is now to be changed, then only the fastening screw has to be loosened.
- the bit holder 20 can then be displaced relative to the base part 40.
- the fastening screw is then tightened again, so that the toothing 26 can be braced with the counter toothing 42.
- FIGS. 2A and 2B Such a changed setting position is shown in FIGS. 2A and 2B.
- the working angle a is now 45 ° (compared to the previous setting of 40 °). 2A and 2B, the fastening screw and the screw head 32 abut one end of the elongated hole 28 and the recess 27, respectively.
- FIGS. 3A and 3B The other maximum working angle a is illustrated in FIGS. 3A and 3B.
- the fastening screw and the screw head 32 abut against the other end of the elongated hole 28 or the recess 27. 3A and 3B, a working angle a of 35 ° is realized. It can be seen that regardless of the setting position of the chisel holder 20, the central longitudinal axis 16 of the chisel 10 is always arranged normal to the contact surface of the base part 40. This enables optimal derivation of the forces generated during work.
- Screw head 32 of the fastening screw selected a cylindrical geometry.
- a lens head geometry can also be selected to improve the contact pressure.
- FIG. 4 A possible embodiment of a base part 40 is shown in perspective in FIG. 4.
- the opposite toothing 42 divided into two partial teeth 42.1 and 42.2.
- the two partial teeth 42.1 and 42.2 are inclined in the direction transverse to the feed direction of the round shank chisel 10.
- This forms a toothed strip-shaped edge 42.3 in the transition area between the two partial teeth 42.1, 42.2.
- the toothing 26 of the bit holder 20 is also designed. As a result of this configuration, the forces acting transversely to the direction of advance of the chisel can be positively transmitted into the base part 40 via the teeth 26 and the counter teeth 42.
- FIG. 5 shows a further embodiment variant of a bit holder changing system.
- the base part 40 is placed with its connecting surface 41 on the surface of a roller body 50.
- the base part 40 has an abutment part 44.
- This abutment part 44 is provided with counter teeth 42 in the form of a star.
- the individual teeth of the counter toothing 42 are directed radially outwards from a common center.
- the central longitudinal axis of the fastening screw, of which the screw head 32 can be seen in FIG. 5, is also arranged in this center.
- a clamping plate 25.1 of the base body 25 of the bit holder 20 can be placed on the system part 44.
- the clamping plate 2.5 is provided with a toothing 26 which is adapted to the counter toothing 42 of the base part 40.
- the toothed connection shown in FIG. 5 is usually referred to as a Hirth toothing.
- the teeth 26 are braced with the counter teeth 42 by means of the fastening screw.
- the fastening screw is loosened, the chisel holder 20 can be gradually offset relative to the base part 40 in accordance with the tooth pitch. This also changes the working angle a of the chisel 10.
- the working angle a can be changed quickly and without great effort.
- the removal tool for example a road milling machine
- the removal tool can be easily adapted to different applications. If, for example, a large working angle ⁇ is selected, a fine surface roughness can be generated in road milling machines. Small working angles a, on the other hand, lead to a large overburden volume with a high roughness depth.
