Description

TECHNICAL FIELD [0001] The present invention relates to a torque collimator, and more particularly, to a torque collimator and a torque collimator using the same.

The present invention relates to a torque adjusting device for a tap collet holding a cutting tool and a torque adjusting method for a tap collet using the same.

For example, a cutting tool for cutting a thread is held by a tap collet. If the torque of the tap collet exceeds the proper value, there is a problem that the cutting tool is damaged or the quality of the workpiece is deteriorated.

Conventionally, to adjust the torque of the tap collet, a tab collet is fixed at a predetermined position using a separate plate provided with a seating jig on which the tap collet is seated, and then the torque setting value of the tap collet is adjusted by manually operating the wrench member Respectively.

Conventionally, in order to reach the target torque value of the tap collet, the operator has to apply a torque corresponding to the target torque value of the tap collet in total amount, thereby causing difficulty in operation and causing musculoskeletal disorders.

However, conventionally, there is a problem that the torque value setting time is long because of using a separate jig depending on the size of the tap collet.

A through hole 7a is formed in the inner socket 7 so that the loading ball 9 is movable in the circumferential direction, And a loading spring 11 is interposed between the bottom of the receiving groove 5a and the inner socket 7. [

When the shaft portion of the cutting tool T is inserted into the boring portion 7b of the inner socket 7 and then held in the boring portion 7b by the above-described structure, the inner socket 7 is elastically deformed by the elastic force of the loading spring 11, In the direction away from the bottom of the receiving groove 5 along the axial direction.

Thereafter, when the loading ball 9 is brought into close contact with the conical slope groove 5b and the outer surface of the shaft of the cutting tool T so that the inner socket 7 does not move any further, the cutting tool T Is loaded into the outer socket (5).
