Abstract

A turn broach machine may include a machining member machining a target to be cut; and an adaptor which is provided under the machining member, supports the machining member, and adjusts a position of the machining member. At the time of adjusting a position of a segment of the machining member from a plate provided in an adapter, the segment moves on an adjusting plate that is mechanically defined, such that work accuracy may be improved to increase marketability and a work time may be decreased to improve work convenience and productivity.

First claim

What is claimed is:

1. A turn broach machine comprising:
a machining member for cutting material from a workpiece; and
an adapter being disposed under the machining member and supporting the machining member, wherein the adapter adjusts a position of the machining member such that an adjusting plate moves along a plate,
wherein the adapter includes the plate supporting the machining member; and
an adjusting part being provided on the plate, the adjusting part including:
the adjusting plate being provided on the plate, and
a stopper being provided on the plate and limiting movement of the machining member.

2. The turn broach machine according to claim 1 , wherein the machining member includes:
segments provided on the adjusting plate of the adjusting part; and
inserts provided on the segments configured for cutting material from the workpiece.

3. The turn broach machine according to claim 2 , wherein the machining member further includes insert cores inserted between the segments and the inserts, wherein the insert cores allow adjusting the relative positions of the inserts.

4. The turn broach machine according to claim 2 , wherein the machining member further includes cartridges mounting the inserts on the segments.

5. The turn broach machine according to claim 2 , wherein the adjusting plate of the plate has a serration formed on an upper surface thereof.

6. The turn broach machine according to claim 5 , wherein a lower portion of the segment has a shape corresponding to that of the serration formed on the upper surface of the adjusting plate of the plate.

7. The turn broach machine according to claim 2 , wherein the segments are coupled to an upper portion of the adjusting plate by fixing bolts.

8. The turn broach machine according to claim 1 , wherein one end of the adjusting plate is supported by a bearing along the plate and an other end of the adjusting plate is provided with an adjusting bolt to adjust the relative position of the adjusting plate with respect to the plate.

9. The turn broach machine according to claim 8 , wherein the other end of the adjusting plate is provided with an adjusting hole having a screw thread formed on an inner peripheral surface thereof to allow the adjusting bolt to be threaded therein so as to ascend and descend with respect to the plate.

10. The turn broach machine according to claim 8 , wherein the adjusting plate has a trapezoidal shape in which a lower surface thereof is short.

11. The turn broach machine according to claim 10 , wherein inclined surfaces corresponding to each other are formed between the first and second supports and are formed in the same direction as that of the inclined surface formed on one end of the adjusting plate.

12. The turn broach machine according to claim 8 , wherein the plate has a first support provided on an upper portion of the center thereof, the adjusting plate has a second support provided on a lower portion of the center thereof, and the first and second supports have a bearing additionally provided therebetween.
