Definitions
- the invention relates to a deep rolling roller head of a deep rolling tool for deep rolling radii or recesses on the bearing journal of crankshafts with the help of deep rolling rollers, which are freely rotatable in roller cages, which are at a mutual distance from each other approximately in the middle of the crankshaft facing underside of the prismatic housing Support the deep-rolling roller head on the front side at the end of the long leg from two L-shaped holders, each with a long and a short leg, which can be adjusted and locked in the direction of the center of the underside by the long leg having an elongated hole into which a first screw engages, via which the respective L-shaped holder is held on the underside of the housing, while a second screw engages through a hole in the short leg and with its outer end in a hole in the end face of the housing adjoining the underside , wherein the second screw is intended to adjust the exact position of the roller cage with respect to the center of the bottom.
- the known deep rolling roller heads without exception, have in common that an exact adjustment of the deep rolling rollers with respect to the center of the deep rolling roller head is extremely difficult and requires a great deal of skill from the person skilled in the art.
- An exact adjustment to the center of the deep rolling roller head is not even desirable, but a presetting in the order of magnitude between 0.1 and 0.2 mm is carried out against the direction of the rotating crankshaft.
- devices have therefore already been developed which should make setting easier for the person skilled in the art and at the same time should achieve a setting result of sufficient accuracy. This is understandable when, as is known from the prior art, the L-shaped holders for the roller cages have to be set and fixed by two screws each on the deep-rolling roller head. In total there are four screws per deep rolling roller head, which fix the L-shaped holder, the exact adjustment of which is difficult and time-consuming.
- Another way that the present invention takes is to simplify the deep rolling roller head in a suitable manner in such a way that a firm stop is created for one of the two roller cages before the second roller cage is placed against it and the associated L-shaped one with the insertion of the deep rolling roller Holder is fixed.
- the deep rolling roller head is to be simplified and the setting of the deep rolling rollers can be carried out with greater accuracy without additional effort.
- this object is achieved in that one of the two end faces of the housing adjoining the underside has a predetermined first distance from the center of the underside over at least a portion of its length, -
- the short leg of the L-shaped holder in question is supported on at least a portion of its inside facing the housing on that portion of the housing which is at a first distance from the center of the underside, while
- the other second L-shaped holder is brought to a stop with its short leg on surfaces of the housing which have a predetermined first fixed distance from the center of the housing.
- the roller cage then comes to rest on this end face.
- the second holder is fixed to the deep-rolling roller head with two screws, one of which reaches through the elongated hole in the long leg of the holder and engages in the housing of the deep-rolling roller head.
- the second roller cage is pushed up with the help of the first L-shaped holder and this first L-shaped holder is attached to the one by one screw in the long leg and one screw in the short leg Housing fixed, as is already known from the prior art.
- the second end face facing away from the front of the housing is preferably provided with a fixed stop for the second L-shaped holder.
- the second screw is inserted into a threaded hole in the housing of the deep rolling roller head and screwed there.
- FIG. 1 is a side view of a deep rolling roller head
- FIG. 2 is a section through the deep rolling roller head of FIG. 1 along the line II-II and 3, 4 and 5 a second L-shaped holder in the three usual views.
- the deep-rolling roller head 1 of a deep-rolling tool (not shown) for deep-rolling radii or recesses on the bearing journals of crankshafts (not shown) works with the aid of deep-rolling rollers 2, which are freely rotatably guided in roller cages 3.
- the deep rolling rollers 2 are guided in the roller cages 3 with play, the guide surfaces of the roller cages 3 supporting the deep rolling rollers 2 on two opposite sections of their circumference.
- the play between the deep rolling rollers 2 and the roller cages 3 is between 0.1 and 0.5, preferably 0.2 mm.
- the two roller cages 3 are at a mutual distance 4 from one another.
- the roller cages 3 are located approximately in the center 5 of the underside 6 of the prismatic housing 7 of the deep rolling roller head 1 facing the crankshaft 1.
- the roller cages 3 are each supported on the end face 8 at the end of the long leg 9 by two L-shaped holders 11.
- the two L-shaped holders 11 each have a long leg 9 and a short leg 10.
- the L-shaped holder 11 can be fastened on the underside 6 of the housing 7.
- each of the two L-shaped holders 11 has an elongated hole 12 into which a first screw 13 engages, via which the respective L-shaped holder 11 is held on the underside 6 of the housing 7 of the deep-rolling roller head 1.
- a second screw 14 extends through a bore 15 in the short leg 10 of the L-shaped holder 11 and with its outer end 22 into a threaded bore 23 or 26 in the bottom 6 Adjacent end face 16 of the housing 7.
- the second screw 14 is provided to reliably transmit the forces exerted by the deep-rolling rollers 2 via the roller cages 3 to the deep-rolling roller head 1.
- the second screw 14 engages through the bore 15 in the short leg 10 into the bore 26 in the end face 16 of the deep rolling roller head 1.
- a section 17 of the end face 16 of the housing 7 adjoining the underside 6 has a first fixed distance 18 from the center 5 of the housing 7.
- the inside of the short leg 10 of the second L-shaped holder 11 is supported on the section 17 3.
- the end face 8 of the long leg 9 also has a second predetermined distance 20 from the section 17.
- the second screw 14 is provided for engaging with its front end 22 in a threaded bore 23 of the housing 7 through a bore 15 in the short leg 10.
- the first L-shaped holder 11 shown on the right half of FIG. 1 is adjusted and fixed in the manner known per se on the housing 7 with the aid of the two screws 13 and 14.
- the play between the deep rolling rollers 2 and the ones holding the deep rolling rollers 2 can be there Roller cages 3 can be adjusted more precisely; it is between 0.1 and 0.5, preferably 0.2 mm.
- a pin 24 on the front end face 21 of the housing 7 is used to attach a tool (not shown) for handling the deep-rolling roller head 1.
- a tool (not shown) for handling the deep-rolling roller head 1.
