Definitions
- the invention relates to a tool holder with a chisel holder which has a chisel holder for receiving a chisel which can be exchanged therein in a holding projection, wherein the chisel holder has a bore-like shape and has a chisel insertion opening, wherein the chisel holder has a fastening side with a fastening projection and Facing away facing an outer side, and wherein during the tool insert centrifugal forces act in the direction of the mounting side to the outside.
- Such an arrangement is known from DE 43 22 401 C2.
- Such tool holders are used, for example, in road milling machines, soil stabilizers, mining machines or the like.
- the bit holder is usually grown on a base part of the surface of a milling drum.
- the chisel holder is used for exchangeable picking up a chisel in the chisel holder.
- the chisel is held with play in the tool holder, usually with the aid of a clamping sleeve. He is then captive in the chisel, but kept freely rotatable about its central longitudinal axis.
- the chisel with its chisel tip works the surface to be machined, for example a road surface.
- the surface material is crushed. This results in coarse and finer removed surface particles. These are discharged from the area of the milling drum. The fine particles can penetrate into the area of the bit receptacle. They settle in and hinder the free rotation of the chisel. Sometimes they completely set the chisels. The reduced rotational capability leads to rapid wear of the bit. If this is not detected in time, then the chisel holder is damaged. This then requires a cost intensive exchange measure.
- the fine particulate material introduced into the bit holder hampers the replacement of the bit from the bit holder.
- the retaining lug has an opening which penetrates the inner wall of the bit receptacle and creates a spatial connection to the environment, and in that the opening opens the bit receptacle in the direction towards the outside.
- the scrap material introduced into the area of the bit receptacle is transported by the rotating bit along the longitudinal axis of the bit in the direction away from the bit head. It thus creates a "pumping action", which is supported by the periodic tool intervention.
- the bit holder now has an opening in the area of the bit receptacle. This is arranged on the centrifugal side. When the waste material is fed into the bit holder, it enters the area of the opening and can escape into the environment again. In this way, the free rotation of the bit is maintained.
- the bit holder is designed as a through hole and the chisel insertion opening facing away has an expulsion opening, and that the opening opens the bit receptacle in the region of the expulsion opening and extends from the expulsion opening in the direction of the chisel insertion opening.
- the user is then offered a generous accessibility to the bit holder, which allows a quick and easy bit disassembly.
- a chisel with a chisel shank is inserted into the chisel receiver, and that the opening is arranged at least in the region of the chisel holder assigned to the shank end.
- the knowledge is made use of, that the registered space material is transported in the direction of the chisel axis to the free end of the chisel shaft.
- the opening is arranged in the region of the shank end of the bit, the accumulating here accumulation material can easily get into the environment.
- the opening can be arranged to close to the shaft end, to the shaft end or the shaft end partially across.
- the opening can then be easily manufactured if it is provided that it is designed as a slot-shaped recess which has two boundary surfaces extending parallel to one another in the direction of the longitudinal axis of the bit receptacle, wherein the boundary surfaces are at a distance from one another smaller than or equal to the bore diameter of the bore
- bit receptacle for a disassembly tool is further enhanced when it is provided that the bit holder is attached to a base member, that the base member has a recess which provides access for a disassembly tool to the bit receptacle, and that the recess merges into the aperture ,
- a tool holding device may be such that at least one liquid spraying device is associated with the bit holder, which introduces liquid through the opening into the bit receptacle. The liquid then dissolves the waste material collecting in the bit receptacle so that it can easily be discharged through the opening. This happens particularly effectively when it is provided that the liquid spraying device applies a jet of liquid to the free end of the bit shank.
- FIG. 2 shows the bit holder shown in FIG. 1 in a perspective rear view
- Fig. 3 shows the bit holder of FIG. 2 in different views.
- FIG. 1 shows a tool holding device which has a base part 40.
- This can be welded by means of a fastening surface 41 on the curved surface of a milling drum (not shown), for example, welded.
- the base part 40 has a plug-in receptacle 42 into which a fastening lug 1 1 of a chisel holder 10 is inserted.
- the attachment lug 1 1 knows a recess 13 with a pressure surface 13.1.
- the pressure surface 13.1 is acted upon by a pressure screw 46, which is screwed into an internal thread of the base part 40.
- the pressure screw 46 is accessible through a tool feedthrough 45 for a screwing tool.
- the pressure screw 46 acts on the pressure surface 13. 1 in such a way that the fastening projection 1 1 is pulled into the plug-in receptacle 42.
- front side prism-shaped guide surfaces 12 are pressed against correspondingly formed mating surfaces of the base part 40.
- the configuration of the bit holder 10 can be seen in more detail in FIGS. 2 and 3.
- the bit holder 10 has a holding lug 15 following the attachment lug 1 1.
- This forms a rear support surface 14 which rests in the assembled state on a counter surface 43 of the base member 40.
- the retaining lug 15 has a cylindrical projection 16, in which wear marks formed as circumferential recesses are groove-likekohl ⁇ works.
- the cylindrical projection 16 terminates with a support surface 18.
- the bit holder 20 is designed as a cylindrical through hole. It forms in the region of the support surface 18 a chisel introduction opening 24 and this averted a Austreibö Stamm 21st
- an opening 22 is incorporated in the holding lug 15 in the holding lug 15 .
- the opening 22 opens the bit receptacle 20 toward the centrifugal force side of the bit holder 10. This can be clearly seen in FIG. 1.
- the bit holder 10 has a facing the base part 10 mounting side and this facing away from the centrifugal force side.
- a bit 30 is inserted into the bit receptacle 20 of the bit holder 10.
- the chisel 30 has a cylindrical chisel shaft 31 to which a chisel head 32 is integrally formed.
- a wear protection disc 35 is pushed in a known manner. This is circular and covers the support surface 18 of the chisel holder 10 completely.
- the chisel head 32 is supported centrally on the anti-wear washer 35.
- On the chisel shank 31 a longitudinally slotted clamping sleeve 34 is pushed. This has holding elements 34.1, which engage in a circumferential groove of the drill collar 31 to form a rotary bearing.
- the bit 30 is thus freely rotatable in the clamping sleeve 34, but held captive axially.
- fine space material can reach the area of the bit receptacle 22. This finds its access in the area between the chisel head 32 and the anti-wear washer 35 or between the anti-wear washer 35 and the support surface 18 of the chisel holder 10. It passes through these paths in the chisel holder 20 and in the present case in the area between the drill collar 31 and the clamping sleeve 34. As a result of the Dreh ⁇ movement and a limited axial play of the chisel shank 31 in the chip sleeve 34 creates a pumping effect.
- the spacer material often forms a sticky suspension, if coolant, for example water, is used during the removal process.
- the space material is removed by the chisel insertion due to the pumping effect along the bit axis. Opening in the direction of the Austreibö réelle and thus promoted against the centrifugal force direction until it emerges from the intermediate region between the drill collar 31 and the clamping sleeve 34 at the free end of the drill collar 31.
- the centrifugal forces acting here on the accumulating space material now move this through the opening 22 from the bit receptacle 20.
- the opening 22 extends a little way over the free end of the clamping sleeve 34 and thus also of the drill collar 31st Thus, the Austragungsrea can take place reliably. This would also be possible if the opening 22 closes off with the free end of the clamping sleeve 34 of the drill collar 31 or is offset a little way.
- the opening 22 is in spatial communication with a rear-side recess 44 of the base part 40.
