Title: Grinding head for machining constant internal profiles
IPC: B24B19/12
Filed: 1975-12-30
Abstract: 1537280 Grinding ROTO DIESEL 30 Dec 1975 [10 Jan 1975] 53084/75 Heading B3D A grinding head for machining internal profiles of components to a constant size comprises a grinding wheel 5 rotatable about its axis, a generator profile 2 arranged to remain in contact with a detector roll 29 as it moves relative to the roll, and means to impart to a component 6 to be machined and is related to the grinding wheel a movement which is homothetic with the movement of the generator profile as related to the detector roll, the detector roll being of variable diameter so as to remain in constant ratio with the diameter of the grinding wheel after each dressing of the wheel. A component 6 is rotatably mounted in a head 12 which is supported by arms 12<SP>1</SP> for pivotal movement on a shaft 14 carried by bearings 15 in a housing 10. A second head 13 is likewise pivotably mounted by arms 131 on the shaft 14 and rotatably carries the generator profile 2. The component 6 to be machined and the generator profile 2 are synchronously rotated by gearing 17, 19 and 16, 18 from the shaft 14, the gearing being driven by reduction gearing 22 from a variable speed motor 20. The generator profile is engaged by the detector roll 29 which is in the form of a tapered cylinder having its generatrix parallel to the axis of the shaft 14 and carried by a slide 28 movable axially stepwise in a housing 27 by a stepping motor 30 when a pneumatic or hydraulic clamp 32 is released. A lever 24 is, at one end, mounted on a pivot 25 and, at the other end, guided in a fork 26, and a spring 34, which is adjustable by a screw 35, urges a slide 36 into engagement with the lever which, in turn, bears on the head 13 to press the generator profile 2 against the detector roll 29. A spring 37 connected to an adjustable slider 38 on the lever 24, urges the head 12 against the lever, the arrangement being such that pivotal movement of the head 13 about the shaft 14 as the generator profile 2 moves over the detector roll causes a corresponding, although reduced, movement of the head 12 so that the component is ground to the same but smaller shape as the profile by the grinding wheel 5. When the diameter of the grinding wheel is reduced as a result of stressing, the stopping motor 30 is actuated, after release of the clamp 32, to move the detector roll 29 so that its operative diameter is varied in accordance with the reduction in diameter of the grinding wheel. In another embodiment, the spring 34 is acted upon by a cam driven synchronously with the shaft 14 so as to exert a constant pressure on the head 13 during its pivotal movements.
