Description of drawings
Below will describe the present invention in detail by the embodiment that a back is represented in the accompanying drawings.This accompanying drawing is represented the summary profile of cutter holder of a quick-change type chuck form of the toolroom machine that the portable power of a screw-driving machine form drives.
The specific embodiment
The end of summarily representing the toolroom machine 10 that portable power drives in the accompanying drawings, the toolroom machine that this portable power drives forms by screw-driving machine, drilling machine or similar tool machine and by unshowned, an especially electric drive motors and a postposition, also unshowned speed changer drives.This portable dam machine 10 has illustrated axial arranged a, cutter holder 20 of quick-change type chuck form especially in its end.This cutter holder 20 has a maintenance sleeve 21 that has locking system 22, and being used for releasedly, one of locking can be received in sleeve 21, the unshowned cutter of maintenance.This cutter will by its axostylus axostyle be received in keep sleeve 21 one axially in the reception cavity 23, this reception cavity for example has polygonal profile, hexagon profile for example is with the respective cross-sectional shapes of adaptive cutter axostylus axostyle.Locking system 22 has a locking sleeve 24, and this locking sleeve is overlapped on the maintenance sleeve 21 and can keeping axially mobile and fixing on the sleeve.In the drawings footpath make progress annular projection part 25 inside the left side on an O RunddichtringO 26 be used for this and fix, the sealing circle is received in the cannelure 27 that keeps sleeve 21 and as annular projection part 25 backstop in left side in the drawings.
In the zone of the front end 28 that keeps sleeve 21, receiving a collar 30 in the cannelure 29 here, this collar is used for axially supporting a spring 31, this spring with its left end shaft in the drawings to ground be bearing in annular projection part 25 facing to a side on and this spring is used in opposite end and rests on and be positioned on the support ring 32 that keeps on the sleeve 21, this support ring is supported on the described collar 30.This spring 31 plays a stage clip, and its pre-pressure of the spring is guaranteed by support ring 32 and collar 30.On the lock position shown in this locking sleeve 24 remains on constantly by described spring 31, one is inserted in cutter in the reception cavity 23, axially is locked in this lock position as the axostylus axostyle of a screwdriver.The lock piece 33 of at least one radially mobilizable ball form is used for this locking, this lock piece anticreep lands and is remained on like this in the additional radial hole 34 that keeps sleeve 21, has been release and has discharged by locking sleeve 24 mobile at least one lock piece 33 mobile radially outwardly cutter that also can make in radial hole 34 that is radially discharged by annular projection part 25 that makes on the right side in figure.On the position shown in the figure, at locking under unshowned, situation of being inserted in the cutter in the reception cavity 23 lock piece 33 radially pressed to the center of rotation direction of cutter holder 20 by annular projection part 25.
The collar 30 that is arranged in described front end 28 zones has guaranteed the Functional Capability of the cutter holder 20 of quick-change type chuck form.Because the position of collar 30, the relative mechanical load of this collar, especially damage irresistance.If occur damaging in this zone, this collar 30 will damage, and make cutter holder 20 lose its repertoire ability thus.
The outer surface of locking sleeve 24 and this keep the outer surface and the collar 30 of sleeve 21 free front ends may damage the parts that contact with them.In this scope of damaging these parts that the dangerous portable dam machine 10 that for example is present in by the screw-driving machine form is connected to each other.This may be a car body component of having made and gone up lacquer in the vehicle manufacturing, and these parts are to be connected each other or be connected on the parts to be fixed by screw (bolt).
Remedy and on the one hand protect cutter holder 20 for this is made in order to avoid its damage; and protect the parts that connect by portable dam machine 10 to avoid the damage of cutter holder 20 on the other hand; designed: described maintenance sleeve 21 is surrounded by the external protector 40 of their outer surface of protection ground covering outside with locking system 22; this protective device provides the protection to these outer surfaces on the one hand; be used on the other hand protect with them and form the parts that contact, parts for example to be connected.Guaranteed the mechanical part of cutter holder 20 is prevented the protection that damages and the parts that portable dam machine 10 to be used is connected given protection by this protective device 40.This protective device is easy to install and dismounting.Its available simple mode is installed on the portable dam machine 10 of having devoted oneself to work afterwards.If these protective device 40 damaged, be damaged or be worn fully, still guarantee cutter holder 20 function originally fully.This protective device 40 can need not any servicing unit with plain mode and only be installed on the cutter holder 20 with hand.The operation of portable dam machine 10 can not change owing to protective device 40 has been installed.
This protective device 40 will be advantageously by a kind of material soft, vibration damping such as rubber, artificial rubber, and plastics etc. are made.This protective device 40 has a wall part 41, and its especially columniform reaching extends on the whole length of locking sleeve 24 in the axial direction at least substantially.Wall part 41 surrounds locking system on the whole length of locking sleeve 24, this wall part 41 detachably but not removable and/or can not be maintained on the locking sleeve with relatively rotating.This available simple mode realizes that soon wall part 41 is enclosed within on the described locking sleeve 24 and remains on clampingly on this locking sleeve.Should the maintenance effect also be supported so in the case: locking sleeve 24 is provided with embossing in due form on its outer surface, and it can further improve the friction of adhering between the wall part 41 of this surface and protective device 40 as surface roughness.
This protective device 40 stretches and surpasses the free front end 28 that keeps sleeve 21.At this; what be enough to satisfy is: especially pass through a corresponding flange (Bund) axially-extending for columniform wall part 41; and make whole protecting device 40 only partly form by the axially-extending in this cylindrical wall portion and front end 28 zones; wherein the front end face 35 of the described maintenance sleeve 21 of this axially-extending part extend through reaches in this way and not only can guarantee corresponding contact protection to cutter holder 20 but also to the parts that connect by portable dam machine 10.
In illustrated embodiment, this protective device 40 is to constitute like this: its protection ground is covered with the front end face 35 of maintenance sleeve 21 and rests on this end face 35 and be covered with this end face with a loop section 42.This loop section 42 is connected on described wall part 41 distolateral in the case, loop section 42 preferably and this wall part be whole.In this configuration 40 of protective devices by one roughly the protective cover 43 of jar shape constitute, its wall is made of wall part 41 and its end is made of loop section 42, wherein loop section 42 comprises an open-work 44 at the center, this open-work can be passed by the cutter of an insertion.
Protective cover 43 begins to be pulled on its locking sleeve 24 and keeps thereon clampingly from the free front end 28 that keeps sleeve 21; and cover locking sleeve 24 from the outside and keep the free front end 28 of sleeve 21, and cover parts disposed thereon such as support ring 32 and collar 30.
Be appreciated that described protective device 40 can be simply as individual components and unnecessaryly can at any time be installed on the cutter holder 20 afterwards with servicing unit, and also can advantageously be suitable as the parts of the existing portable dam machine 10 of repacking thus.
