As shown in fig. 5 and 6, in the thread turning, the work 7 passes through the groove 6 from the work, the relief groove 72 is formed by moving the tool so that the groove-forming insert 4 approaches the work 7, and the thread 71 is formed by moving the tool so that the thread-forming insert 3 approaches the work 7. The tool withdrawal groove 72 and the thread 71 are machined only by operating a machine tool or setting a program to move the tool, the tool does not need to be switched, machining of the thread 71 and the tool withdrawal groove 72 is simplified, and machining efficiency is improved.
The position of the movable cutter bar 2 is adjustable, so that the width of a workpiece passing through the groove 6 and the distance between the thread machining blade 3 and the groove machining blade 4 are adjustable, when the diameter of the workpiece 7 is smaller, the distance between the workpiece passing through the groove 6 and the thread machining blade 3 and the groove machining blade 4 is adjustable, the cutter is shortened, the cutter is better in rigidity, the vibration during groove machining is small, the feed distance for switching the groove machining state to the thread machining state can be reduced, and the machining efficiency is improved; when the diameter of the workpiece 7 is larger, the workpiece can be widened by passing through the slot 6 and increasing the distance between the thread machining blade 3 and the slot machining blade 4, so that the invention can machine the workpiece 7 with larger diameter. Therefore, the invention has the beneficial effect of strong adaptability.
The specific structure of the fixed cutter bar 1 and the movable cutter bar 2 is preferably as follows: the shape of fixed cutter arbor 1 is rectangular shape, and the shape of activity cutter arbor 2 is "L" shape, and activity cutter arbor 2 includes the vertical portion 22 of cutter arbor horizontal part 21 and cutter arbor, and the position is adjusted in the below of fixed cutter arbor 1 and can be followed the removal of fixed cutter arbor 1 length direction to cutter arbor horizontal part 21 connection, forms the work piece between the vertical portion 22 of cutter arbor and the fixed cutter arbor 1 front end and passes through groove 6. The width of the workpiece passing through the groove 6 and the distance between the thread machining blade 3 and the groove machining blade 4 can be adjusted by moving the movable cutter bar 2 along the length direction of the fixed cutter bar 1.
The specific connection mode of the fixed cutter bar 1 and the movable cutter bar 2 is preferably as follows: the thread and tool withdrawal groove processing tool comprises a fastener 5; the fixed cutter bar 1 is provided with a deformation groove 11 extending backwards from the front end of the fixed cutter bar 1, the deformation groove 11 divides the front part of the fixed cutter bar 1 into two clamping parts 13, and the clamping parts 13 are provided with V-shaped clamping grooves 12 extending backwards from the front end of the fixed cutter bar 1; a diamond-shaped sliding block 23 is arranged on the horizontal part 21 of the cutter bar, and the diamond-shaped sliding block 23 is inserted into the V-shaped clamping groove 12; the fastener 5 connects the two clamping portions 13 and reduces the distance between them, so that the V-shaped clamping groove 12 clamps the diamond-shaped slider 23.
The fastener 5 is threaded through one of the clamping portions 13 and into the other clamping portion 13, and tightening the fastener 5 reduces the distance between the two clamping portions 13.

If the edge orientation of the groove-working insert 4 is the same as the edge orientation of the thread-working insert 3, the rotational direction of the workpiece 7 needs to be different when the relief groove 72 and the thread 71 are worked. Therefore, the arrangement is also beneficial to simplifying processing and improving processing efficiency.
Further, it is preferable that the cutting edge of the groove-processing blade 4 is the same height as the cutting edge of the threading blade 3. In turning, the tool is generally horizontally mounted, and therefore the present arrangement specifically means that the cutting edge of the groove-machining insert 4 is at the same height as the cutting edge of the thread-machining insert 3 when the tool is horizontally arranged. The cutting edge of the groove-machining insert 4 and the cutting edge of the threading insert 3 should be flush with the center of the workpiece 7 at the time of machining. When the height of the edge of the groove machining insert 4 is the same as that of the thread machining insert 3, the tool moves horizontally during machining of the relief groove 72 and the thread 71, and the height does not need to be adjusted.
