Definitions

  • the invention relates to a tool holder system for tools, especially for round chisels, on rollers for the road and Wegebau, with a box welded onto the roller with a Holder for the shaft of an interchangeable holder and surfaces on it Top for the installation of the change holder head, a change holder with a tool holder, its shaft in the holder the box is inserted, and a clamping screw for fixing of the change holder on the box.
  • the present invention is based on the object Tool holder system for tools, especially round shank chisels, to create on rollers, which is characterized by a low overall height and therefore also on small diameter rollers (e.g. 15 to 30 cm) is suitable. Furthermore, a change holder system is said be created in which the exchange of the change holder is simplified becomes. In particular, this should be the case with this exchange required space tangential to the roller can be reduced. Further advantages of the system according to the invention result from the following description.
  • the fixation and centering of the change holder in the box with the help of two on opposite sides of the change holder shaft attacking jaws reduces the space requirement in comparison to known constructions with approximately tangential insertion of the change holder in the box because the stroke length on both jaw bodies is distributed and because of the external position of the attack surfaces a slight ramp-like overlap of the Attack surfaces are sufficient compared to the insertion length of the change holder in the above known construction.
  • the change holder is therefore only radial when inserting and removing from the box moved to the roller.
  • the central axis mentioned above, which is the displacement axis the jaw body is approximately tangential to the circumferential direction of rotation lie.
  • Exchange holder systems are the first target on the top of the formations of the change holder shaft, which inner ends of the cheek body step-like and the second attack surfaces formed on the undersides of these steps.
  • the cheek bodies When moving together the cheek bodies come up with their second attack surfaces the undersides of the steps on the first attack surfaces on the Top of the console-like formations of the shaft to the system and then push the change holder shaft down in the box Direction on the roller surface, causing the collar of the interchangeable holder head comes to rest on the top of the box.
  • Prismatic jaw body with e.g. triangular or square Cross-section can also be an uninterrupted second target have that with only one or two first attack surfaces cooperates on the shaft of the interchangeable holder. Are preferred on each of the two sides of the change holder and on each jaw body two first and second attack surfaces available.
  • the first and / or second attack surfaces are preferred inclined, arched or spherical to the central axis.
  • the first and / or second attack surfaces can be inclined to the central axis Be levels so that when the jaw body moves together the first and second attack surfaces over one another and thereby the Shaft of the change holder is pressed down and anchored.
  • the jaw bodies are in guided their guides without turning. If the jaw body and the Guides have a cylindrical shape. contain the cheek body on the outside one to the length of its maximum displacement range limited longitudinal groove in which a pin engages, which in a in the Box wall provided threaded hole is screwed.
  • the freedom of rotation the jaw body in their guides can be easier can be achieved in that the jaw body and its guides have a square or other polygonal cross section.
  • prismatic jaw bodies too others, e.g. triangular cross sections possible.
  • Systems has an internal thread in the first hole and is the second Hole without thread, it contains an annular groove in which the Head of the clamping screw is included. This type of intervention the screw in the jaw body ensures that at a Screwing the jaw body inevitably moved together or apart be, the movements of the cheek body relative to the clamping screw also take place sequentially can.
  • the clamping screw over opposite threads with the first and engages the second jaw body.
  • drive at Turning the clamping screw inevitably both jaw bodies at the same time and equally fast relative to the clamping screw (with the same Thread pitch in the holes of both jaw bodies) together and apart.
  • an essentially rectangular box 2 is welded onto a roller 1 and contains a receptacle 3 for the shaft 5 of an interchangeable holder.
  • the change holder shown has in its head 4 a receptacle 4 a for a round shank chisel (not shown).
  • exchangeable holders for other tools for example, chiseling chisels, can be fastened and centered in box 2 with differently designed receptacles.
  • the correspondingly designed head 4 of the interchangeable holder has a collar 4 b and comes into contact with the attachment and centering of the interchangeable holder according to the invention on surfaces 2 a provided on the top of the box 2.
  • a vertical support surface 2 b provided on which the force acting in the circumferential direction during operation of the roller component of the shock reaction forces is intercepted.
  • the box 2 has in its front wall and in its rear wall a guide 6 or 7 of quadrangular cross-section, in which a front jaw body 8 and a rear jaw body 9 are slidably guided.
  • the jaw bodies 8, 9 have a square outer cross section corresponding to the guides 6, 7 and each have an axial bore 10 or 11.
  • the bore 10 has a thread 12, while the bore 11 is close to its rear end contains an annular groove 13.
  • the annular groove 13 is formed in the embodiment shown by an extension at the end of the bore 11 and a welded ring 14.
  • the inner end of both jaw bodies 8 and 9 is symmetrical and step-like, with the steps 8 a and 9 a in the embodiment shown in FIG. 1 lying in the central axis 15.
  • a clamping screw 16 is screwed into the thread 12 of the jaw body 8 and lies with its head 16 a in the annular groove 13, so that it is not axially displaceable in the jaw body 9.
  • the screw 16 with its Imbuskopf 16 a (not shown) through the ring 14 to be rotated therethrough, thereby changing their length of engagement in the thread 12 and thereby can be changed 8,9, the axial distance of the shoe body with an Allen key. Since the jaw bodies 8, 9 in their guides 6 and 7 are not rotatable, the step surfaces 8 a and 9 a also retain their position relative to the shaft 5 during the axial displacement of the jaw bodies.
  • the shaft 5 of the interchangeable holder has an approximately rectangular cross section which is essentially adapted to the receptacle 3 in the box.
  • the shaft 5 has a central slot 17 which is open on the underside and extends from its front side to its rear side and in which part of the screw 16 is received.
  • the shaft 5 is laterally guided in the receptacle 3 of the box 2 through four surfaces 5 c , between which the side wall has a recess 5 d .
  • FIG. 3 shows a schematic perspective view of the interchangeable holder 4, 5 and the jaw body 8 of the system shown in FIG. 1, which is retracted from the interchangeable holder.
  • the step surface 8 a of the jaw body 8 is below the highest point of the curved surface 5 b .
  • the front edge 8 b of the step surface 8 a therefore meets the curved engagement surfaces 5 b , so that when the jaw bodies move further together, the edge 8 b runs over the curved surfaces 5 b in a ramp-like manner and the interchangeable holder in the receptacle 3 pulls, whereby the collar 4 b is fixed and centered on the support surface 2 a of the box 2.
  • the interchangeable holder head 4 is offset from its shaft and against the box 2 by an angle of approximately 7 ° in order to ensure the rotation of the round shank chisel (not shown) inserted into the receptacle 4 a .
  • the contact surface 2 b is arranged obliquely to broadly absorb the impact reaction forces acting on the change holder.
  • FIG. 5 shows an embodiment in which, in contrast to the embodiment according to FIG. 3, the upper sides of the console-like projections 5 a of the interchangeable holder shaft are not curved, but are designed to rise flat and ramp-like towards the center of the interchangeable holder. Accordingly, the step surface 8 a of the jaw body 8 is formed as a flat surface inclined to the axis 15.
  • the embodiment of the quick-change holder system shown in FIG. 6 differs from that in FIG. 1 in that, instead of the engagement of the screw head 16 a in the annular groove 13, the bore 11 of the jaw body 9 contains a thread 18 which runs counter to the thread 12 of the bore 10 of the Cheek body 8 is.
  • the tensioning screw 16 also has a thread in the area of the thread 18 which is opposite to the thread at the front end of the screw 16.
  • a rotation of the screw 16 therefore, like in the embodiment according to FIG. 1, causes the jaw bodies 8, 9 to move together and apart, so that the interchangeable holder shaft 5 is fixed and centered in the receptacle, as in the embodiment according to FIG. 1, or for the purpose of exchanging the Exchange holder can be solved.
