Definitions
- the invention relates to the field of machining rotationally symmetrical bodies, especially rotors, such as compressor wheels, turbine wheels, compressors and the like.
- it relates to a method for clamping rotationally symmetrical bodies according to the preamble of the method claim, a device for clamping rotationally symmetrical bodies according to the preamble of the device claim and a rotationally symmetrical body according to the preamble of the subject claim.
- Rotally symmetrical bodies that are later used as components in machines or are otherwise used, such as pipes, shafts, spindles, wheels, rotors, are first produced in the form of blanks that have the basic shape of the desired body.
- the blanks can be produced, for example, by casting, sintering, injection molding, forging, etc.
- machining is usually required, such as cutting, drilling, turning, milling, grinding, etc.
- the chuck generally comprises a collet which generally has at least three clamping jaws for rotationally symmetrical bodies.
- the support element obtains a centering effect, for example, by applying a spring force counteracting the tensile force to the support element. Is the spring force slightly less than the tensile force and dimensioned so that when the body hits the Support element the support element initially yields in the axial direction, so it is possible to pull the rotationally symmetrical body even more precisely centrally against the support element and thus fix it.
- the pulling force can be very easily transferred to the body with the help of a type of tie rod, which is connected to the body quickly and easily, for example by means of a quick coupling.
- tie rod with radial play axially and concentrically to the axis of rotation of the rotationally symmetrical body.
- the radial play particularly advantageously in conjunction with the spring element acted upon by the spring element, causes an exact, central fixation against the support element without the body being misaligned.
- the body is additionally pulled against an axially stationary centering device with a support area which is arranged axially spaced from the first side of the body and is aligned in the same way as the first side, then an even more stable fixation of the body is obtained, which provides the exact central position of the body also stabilized against vibrations.
- This is very advantageous, especially when it comes to machining operations that involve great forces on the body.
- the centered clamping of the body is the more stable the closer the centering device is to the location where the machining operation is attacking
- the rotationally symmetrical body to be clamped is a rotor with integrally formed blades
- a particularly stable clamping is obtained if a centering device is selected, the centering surfaces of which grip between the blades like fingers.
- a centering device whose centering surfaces cooperate with the blade edges.
- the method described above for clamping a rotationally symmetrical body for the purpose of machining can be carried out with a device which comprises a tie rod which is guided axially with radial play in a wall of the device which forms a support element for the body in such a way that it is axially and can attack the body to be clamped concentrically to the axis of rotation.
- a particularly good centering can be achieved with a support element which can be moved in the axial direction, preferably without play, and which is in particular spring-supported on a fixed stop of the device. It is particularly advantageous if the support element is either bell-shaped so that it can encompass a body to be clamped in a centering manner, or if it is designed in the form of a dome or a tip which then centers in a recess or concave bearing surfaces of the body to be clamped.
- the tie rod is provided with a coupling device, which is preferably designed in the form of a quick coupling and can be connected to a coupling unit of the body to be clamped, the body to be clamped can be clamped very easily and, above all, quickly in the device and can also be removed from the device.
- the support element is provided with support surfaces arranged concentrically to the axis of rotation of the body to be clamped, this favors a central clamping. Particularly good results are achieved with a support element whose support surfaces are inclined against the axis of rotation.
- the support surfaces touch at least along a defined outer circumference and form an annular support surface.
- An axially spaced-apart centering device which is provided with centering surfaces arranged concentrically to the axis of rotation of the body to be clamped and preferably inclined against the axis of rotation, enables even more secure clamping of rotationally symmetrical bodies.
- a device according to the invention in which the tensile force of the tie rod and the spring force counteracting the tensile force can be adjusted.
- Interchangeable, differently designed support elements also contribute to very good clamping results and, if the centering device is present, interchangeable, differently designed centering devices. Adjusted to the body to be clamped (geometry, weight, etc.), the support element, centering device, spring force and tensile force can then be selected. Very cheap, especially for rotationally symmetrical bodies such as rotors with blades, are e.g.
- the number of centering surfaces must then of course be matched to the number of rotor blades, so that the centering surfaces engage between the rotor blades.
- Rotationally symmetrical bodies in particular rotors, which have on a first side a coupling unit that is centered with its axis of rotation and a support area with at least three support surfaces arranged concentrically to the axis of rotation are particularly suitable for clamping in the device according to the invention.
- the contact surfaces are oriented away from the center of the body towards the first side.
- the coupling unit can be subjected to tensile stress and can be connected particularly easily to a coupling device of opposite design. For quick clamping and unclamping, it is advantageous if the coupling unit is designed in the form of a quick coupling. This can be realized very easily with a
- the coupling unit which has the shape of a concentric hollow cylinder or hollow polygon arranged in the body.
- the coupling unit is designed as one half of a bayonet lock, in another advantageous embodiment as one half of a screw connection.
- the bayonet lock advantageously has a stop as an overturn protection, as is known for bayonet locks.

- the contact surfaces can also be designed as surfaces which are curved convexly or concavely towards the axis of rotation and towards the first side.
- the bearing surfaces are connected to one another and form a closed ring surface.
- the body can also be clamped in with the aid of a centering device and thus fixed particularly well.
- the bearing surfaces are designed to be inclined with respect to the axis of rotation.
- the angle of inclination ⁇ for the contact surfaces of the centering areas is in the range from 15 ° to 100 °, preferably 20 ° to 60 ° and in particular 30 °. Another good possibility is to make these contact surfaces as convexly or concavely curved surfaces towards the axis of rotation.
- the bearing surfaces are connected to one another and form an annular surface.
- the body has a marking that enables the body to be always oriented in the same way in the room, it is also possible to ensure that the clamping is always the same and precise.
- the easiest way to produce the rotationally symmetrical body is as a cast body.
- the coupling unit, the contact surfaces and preferably, if present, the marking can already be produced simply and inexpensively using essentially casting technology.
- Rotors, in particular with rotor blades molded in one piece, can also be produced very advantageously in the form of the rotationally symmetrical bodies described above. It is particularly advantageous in the case of such rotors to arrange the bearing surfaces at least on the second side of the body between the rotor blades and to preferably integrate the coupling unit in the hub.

- the coupling device 63 of the tie rod 64 is inserted into the coupling unit 18 of the rotationally symmetrical body 10 and the tie rod 64 is rotated, so that the tie rod 64 is detachably but tensile connected to the rotationally symmetrical body 10 by means of the coupling device 18.
- the tie rod 64 is withdrawn axially through the through opening 62 and the contact surfaces 24 of the contact area 22 are brought into contact with the support surfaces 73 of the support element 72.
- the contact surfaces should also be at this point in time 24 'of the centering region 28 of the rotationally symmetrical body 10 come into contact with the centering surfaces 82 of the centering device 76.
- the support element 72 yields a little axially until the spring force F2 and the tensile force F1 are in equilibrium or the spring 75 is compressed accordingly and the support element 72 is fully supported on the annular flange 68 of the stop 60. Due to the special design of the support surfaces 73, centering surfaces 82 and support surfaces 24, 24 '- curved or inclined - the rotationally symmetrical body 10 is automatically coaxially centered when tightened against the support surfaces 73 or support and centering surfaces 73, 82.
- the resilient support element 72 supports this. Misalignment can be avoided by the axial guidance of the tie rod 64 with radial play 66. If the body 10 to be clamped has a marking 9 which allows it to be clamped in the device 50 with exactly the same spatial orientation, then an exact, central clamping is again possible even if a reclamping is necessary. If the marking 9 has already been introduced into the cast body in the case of a cast body, undesired unbalance effects, such as can occur with markings which are subsequently mechanically introduced, can be avoided. It goes without saying that cast-in markings should be applied in such a way that they are still visible on the clamped body as far as possible and do not impair its function when the finished body is used. It goes without saying that the individual configurations of the individual elements of the rotationally symmetrical bodies and of the device can be combined in a technically meaningful manner by the person skilled in the art.
