Definitions
- the invention relates to a chuck according to the preamble of claim 1.
- Such a chuck is known from DE 29 34 428 C2, the window-shaped opening of the bush receiving the ball opening in the region of one of the hexagonal surfaces of the cavity.
- the opening is as in
- W insertion direction of the tool is designed longitudinal slot.
- the inner wall is equipped with support shoulders in such a way that two rectilinear support shoulders are connected to one another by arched support shoulders.
- the longitudinal slot is to be produced by means of a finger milling cutter, there is an identical cross-sectional design of the support shoulders.
- the longitudinal slot-like opening is provided so that when the actuating sleeve is inadequately displaced, the
- the object of the invention is based on the object of designing a generic chuck in a simple manner in terms of production technology in such a way that, in addition to easy insertion and release of the tool, a large holding force acts on the inserted tool when the tensile load acts on it in the direction of extraction .
- the triggering of the tool must take place in a will-oriented manner, namely by displacing the actuating sleeve against spring action, the clamping surface moving away from the ball with the same being released in the radial direction. After release, the tool is again easily removable. If the actuating sleeve is not in the release direction, one can open the ball acting force not to move the actuating sleeve, since the clamping surface has such an angle to the longitudinal axis of the chuck, so that this creates a self-locking effect.
- such a dimensional adjustment is chosen that the diameter of the ball is smaller than half the shaft end corner dimension and more than twice as large as the width of the corner recess lying in the axial direction of the shaft. It can therefore z. B. with ball diameters that are at 2-3 mm
- H lie, which generate the aforementioned large holding force. Furthermore, it is advantageous if the support shoulders of the hollow penetrating one of the polygonal edges have a different thickness, seen in the circumferential direction. Bit-shaped tools manufactured with larger tolerances can also be held sufficiently firmly. It particularly applies to tools that are manufactured by cold working. If tools with a large undersize are used, the ball can penetrate right up to the support shoulders
- the rolling behavior of the ball in the withdrawal direction of the tool is less favorable than in the transverse direction, which also contributes to an improved fit of the tool.
- the strength of the support shoulders can be reduced to zero. Nevertheless, there is sufficient support by the support shoulders running transversely to it.
- the arrangement of the opening forming the support shoulders at the level of one of the polygonal edges allows the wall thickness of the bushing to be kept low in comparison to the previously known embodiment 5, combined with the reduced ten spatial shape, without this resulting from a reduction in the ball diameter.
- 1 is an approximately five times enlarged representation of a chuck designed according to the invention with dash-dotted tool designed as a screwdriver bit,
- FIG. 8 shows a longitudinal section corresponding to FIG. 4 with the tool inserted
- FIG. 9 shows the section along the line IX-IX in FIG. 8.
- the chuck designated as a whole by the number 1, has a clamping pin 2 which is continued in a stepped threaded bolt 3. The latter engages in a central threaded bore of a bush 5.
- a lock nut 6 arranged thereon, which is braced against the facing end edge 7 of the bush 5.
- the threaded bore 4 opens into a cavity 8 which runs in the longitudinal direction of the sleeve 5 and has a hexagonal cross section.
- the length of the cavity 8 is greater than that of the threaded bore 4.
- the sleeve 5 can be screwed onto the threaded bolt 3 such that it also projects into the interior of the cavity 8.
- the front end of the threaded bolt 3 closes with the bottom 9 of the cavity 8.
- the sleeve 5 is provided with an outwardly directed collar 10, which also serves to guide an actuating sleeve 11 overlapping the sleeve 5.
- the same has a cylindrical and a conical section 12, 13.
- the cylindrical section 12 is guided by the collar 10 of the sleeve 5.
- At the free end of the cylindrical section 12 there is a guide ring 14 with a bevel 15 on the end face, which is overlaid by an inward flanging 16 of the cylindrical section 12.
- One end of a compression spring 17 which surrounds the bush 5 is supported on the guide ring 14.
- the other end of the same is supported on the collar 10.
- the actuating sleeve 11 is acted upon in the insertion direction x of the tool.
- the actuating sleeve 11 is provided with a limit stop by an inner one located in the transition area between the two sections 12, 13 Ring step 18, with which the actuating sleeve 11 abuts the collar 10, cf. Fig.
- the conical section 13 has a wedge-shaped falling clamping surface 19 on the inside of the sleeve. This runs at an angle alpha of 85 to the chuck longitudinal direction and is therefore in the area of self-locking.
- the smallest diameter of the clamping surface 19 corresponds to the outer diameter of the bush 5.
- FIG. 2 also shows that when the tool is not inserted, the lower end edge 20 of the bush 5 is approximately aligned with the free end edge 21 of the actuating sleeve 11.
- the clamping surface 19 acts together with a ball 22 which represents a pressure piece and has a diameter d of approximately 3 mm.
- the same is accommodated in a radial opening 23 of the bush 5 in such a way that the longitudinal axis of the opening 23 designed as a bore intersects the associated polygonal edge 24 and also the polygonal edge 25 running diametrically thereto.
- the opening 23 is produced by drilling in such a way that support shoulders 26, 2.7 remain in the region of the inner edge of the opening.
- the support shoulders 26, 27 have different thicknesses such that the thickness of the support shoulders 27 decreases with respect to the regions of the cavity 8 diametrically opposite in the direction of insertion.
- the support shoulders 26 lying in the area of the polygonal edge 24 have a smaller thickness than the support shoulders 27 running transversely thereto.
- the latter are dimensioned so large that they give the ball good support.
- the opening 23 could be drilled in such a way that the strength of the support shoulders 26 could be brought to zero. Still, they would Bring the remaining, transversely oriented support shoulders 27 still provide sufficient support for the ball 22.
- the opening 23 opens into the approximately polygonal edge 24 in an approximately oval opening 28, with the realization of the support shoulders 26, 27, which are of different sizes and areas.
- the embodiment is a screwdriver bit 29 of hexagonal cross-sectional shape which is adapted to that of the cavity 8.
- the screwdriver bit 29 has a working end 30 and forms the corresponding blade there.
- Corner recesses 31 lying on the same cross-sectional plane are provided in the opposite shaft end 32.
- the outlet angle beta of the same can be between 60-120 * according to existing standards.
- the width w lying in the axial direction, depending on the size of the outlet angle, is approximately 0.9 mm in the exemplary embodiment.
- the diameter d of the ball ⁇ , 22 of 3 mm is less than half the shaft end corner dimension E of 7.2 mm and more than twice as large as the width w lying in the axial direction of the shaft.
- the corner recesses 31 lie at the same height with the center of the opening 23 or with the ball 22.
- the insertion of the screwdriver bit 29 requires a displacement of the actuating sleeve 11 against the insertion direction x, specifically in the position shown in dash-dotted lines in FIG. 3.
- the clamping surface 19 of the actuating sleeve 11 thus gives the ball 22 the corresponding free space so that it can be inserted of the screwdriver bit 29 can move outwards in the radial direction.
- the insertion movement is limited when the screwdriver bit 29 acts on the bottom 9 of the cavity.
- the actuating sleeve 11 can now be released, whereupon the compression spring 17 a
- the clamping surface 19 acts on the ball 22 and presses it into abutment with the screwdriver bit 29, the protruding portion of the ball dipping into the facing corner recess 31 of the screwdriver bit 29 while at the same time realizing a two-point abutment with the prismatic ones Surfaces 31 'of the relevant corner recess 31 at the height of their outlet-side corner points 31 * '.
- Each of these two corner points 31 ′′ is the intersection of three intersecting edges, as can be seen particularly well from FIG. 8. In this way, an extremely stable, tight fit of the screwdriver bit used is produced by means of a lock.
- the ball 22 can be supported on the support shoulders 26, 27 when the screwdriver bit is inserted. Since the support shoulders 26 are less strong than the support shoulders 27, there is also a different rolling behavior of the ball 22 in such a way that the rolling behavior in the insertion or removal direction of the tool is less favorable, as a result of which an additional braking effect is generated.
