DEVICE FOR FASTENING METAL RINGS ON MACHINING
WORKBENCHES
Technical Field The invention is related to a metal ring fastening device that enables machining of the outer diameter of the metal ring with manufacturing methods such as turning, grinding and the like by taking the inner sectional profile of the ring as reference.
More specifically, the invention is related to a metal ring fastening device that enables quick and fault-free fastening of metal rings to machining workbenches (lathe, grinding) by helical spring, bolt, ball configurations.
Background of the Invention
The fastening devices used in the art enable fastening of the parts to be machined to the machining workbench by taking the cylindrical inner diameter as reference. Because, the purpose is to concentrically machine (turning or grinding) the outer diameter and the cylindrical inner diameter where the part is fastened.
In the United Stated patent document No.US20l5202694 of the known state of the art, a tightening mechanism developed for fastening the part in a boring, milling or grinding machine configured to turn around a fastening part is mentioned.
In the Chinese patent document No.CNl05643457 of the known state of the art, a clamp developed for grinding the outer rim of a roller bearing is mentioned. The clamp consists of a locking block having a cylindrical jacket, an air cylinder, and a conical rod and locking hole. In the invention, while the roller bearing outer ring is being ground, the outer ring is fixed to the turning machine by a jacket over three jaw chuck.
In the Chinese patent document No.CN20l922347 of the known state of the art, a roller bearing outer surface grinding mechanism is mentioned which comprises a mandrel fixed to the inner end face of the magnetic pole and a pressing mechanism to compress the work piece with magnetic pole. In the invention, outer ring of non- magnetic roller bearings is ground.
However, in the exemplified documents, the inner diameter of the ring cannot be fast and fault-free machined by taking the inner diameter as reference by helical spring, bolt, and roller configuration. Therefore, there exists a need for development of the metal ring fastening device of the invention. Objects of the Invention
The object of this invention is to embody a metal ring fastening device that enables machining the outer diameter of the ring axially symmetrical and concentric with respect to the inner profile.
Another object of the invention is to embody a metal ring fastening device that enables quick and fault-free fastening of the rings to machining workbenches (turning, grinding) by helical spring, bolt, and ball configuration.

1. Conical Compression Piece I
2. Conical Compression Piece P

The invention is a metal ring fastening device that comprises, a conical compression piece II (2) on the tailstock (10) side and a conical compression piece I (1) on the other side which move axially with respect to each other and of which the opposite faces are machined conical, wherein characterized by comprising; a helical spring (4) that is located between the conical compression piece I (1) and the conical compression piece II (2), that enables fastening of the metal ring (3) to be machined to the device by moving the conical compression piece I (1) and conical compression piece II (2) away from each other when there is no axial load,
a bolt (5) that prevents the conical compression piece I (1) and conical compression piece II (2) from completely separating when no compression force is applied,
balls (6) that are located between the conical compression piece 1 (1) and the conical compression piece II (2), that enables taking the inner profile of the ring (3) to be taken as reference and that enables the ring (3) to turn with
the device by transferring the turning moment from the conical compression piece I (1) and conical compression piece II (2) to the inner surface of the ring (3),
the cage (7) that holds the balls (6) together and that enables uniform distribution of the pressure at equal angles when a pressure is applied, centering and locking rods (8) that prevent the cage (7) and the balls (6) from running off center too much and that prevents the ring (3) to be machined from sliding on the device when there is no axial load on the device,
- clamping jaws (9) that are located on conical compression piece I (1) and that enables fastening of the conical compression piece I (1) to the machining workbench.
In the fastening device of the invention, the balls (6) move downwards in vertical direction on the conical surfaces of the conical compression piece I (1) and the conical compression piece P (2).
The fastening device of the invention is connected to the machining workbench (for example to a turning machine) by the clamping jaws (9) located on the conical compression piece 1 (1) as assembled with the conical compression piece 1 (1) and conical compression piece P (2), the bolt (5), the helical spring (4), the balls (6) and the cage (7).
Since initially there is no axial pressure force applied, the helical spring (4) moves the conical compression piece I (1) and the conical compression piece II (2) away from each other. The distance between the conical compression piece 1 (1) and the conical compression piece II (2) increases due to such moving away and the balls (6) come to a smaller diameter position by moving radially inward (towards center) since the distance between the conical surfaces of the conical compression piece I (1) and the conical compression piece II (2) increases.
In this position, the metal ring (3) to be machined is connected to the device (i.e. around the balls (6) at the position where the diameter is small). Then, as the result of the axial pressure force on the conical compression piece II (2) applied by the tailstock (10) of the machining workbench, the conical compression piece II (2) moves towards the conical compression piece I (1) in axial direction. Since the conical surfaces approach each other as a result of such movement, the balls(6) move peripherally outwards (towards bigger diameter) on the conical surfaces of the conical compression piece 1 (1) and the conical compression piece II (2) and so contact the inner profile of the ring (3). Thus, the inner profile of the metal ring (3) to be machined is taken as reference and the ring (3) is clamped on the device by transforming the axial force to peripheral radial force.
The centering and locking rods (8) prevent the ring (3) that is fastened to the device in this way from sliding on the device during machining and enables the ring (3) to turn with the device.
