Prior Art When replacing a cutting tool in a cutting tool holder, the cutting tool holder is clamped in a vice to attach and remove the cutting tool, or the taper shank of the cutting tool holder is inserted downward and a V-groove protruding from the outer periphery of the cutting tool holder is inserted. There is a vertical tool replacement jig that has a downwardly tapered pot that supports the flange surface to be formed, and a wrench is inserted through an opening in the side wall of the jig body to attach and detach the pull stud bolt. . Furthermore, as shown in FIG. 4, a foreign product includes a recess 5 that supports a part of the outer peripheral surface and a part of the outer surface of a flange 4 forming a V-groove 3 protruding from the base of the taper shank 2 of the cutter holder 1. There is a horizontal cutting tool replacement jig in which a fixing key 6 is installed at the bottom of the recess 5 to prevent the cutting tool holder 1 from rotating by fitting into a drive key groove provided in the V-groove 3 to prevent rotation of the cutting tool holder 1. , the cutter holder 1 is hung horizontally on a jig and the cutter is replaced.

干渉してセツトできない。c Problems that the invention aims to solve When clamping with a vise, the tool holder may be damaged, and when using a vertical tool replacement jig, the pull stud bolt must be attached or removed using a wrench inserted through the opening. When doing this, the wrench may interfere with the opening, making attachment and detachment difficult. In the case of a horizontal foreign-made tool replacement jig, a part of the outer surface of the flange 4 is clamped together with the fixed key 6. Therefore, when the diameter of the cutter holder 7 on the opposite side of the taper shank 2 is larger than the diameter of the base of the taper shank 2, the cutter holder 7 interferes with the upper surface of the recess 5 and cannot be set.

保持部である。 An embodiment of the present invention will be described below in detail with reference to the drawings. A gutter-like stepped semicircular groove 9 is recessed over approximately one-half of the area occupied by the upper surface of the trapezoidal jig main body 8. A locking portion main body 10 having a half-cut donut shape is fitted into the end of the stepped semicircular groove 9, and a locking protrusion 11 having a trapezoidal cross section is integrally formed in the diametrical direction of the inner peripheral surface of the locking portion main body 10. At the same time, the side surface of the locking part main body 10 is cut in the axial direction until it reaches the center of the locking protrusion 11 to form a keyway 12, and a stopper 13 is provided at the end of the keyway 12. Furthermore, a guide groove 14 is provided in the axial direction of the locking part main body 10 on one side wall forming the key groove 12, and the inner part of the guide groove 14 is formed in the shape of a blind hole. A sliding key 15 that is slightly bulkier than the height of the locking protrusion 11 is slidably inserted into the keyway 12, and a ball 1 is inserted into the side surface of the sliding key 15.
6 is rotatably loaded and the ball 16 is loosely fitted into the guide groove 14 to mount the sliding key 15 so as not to fall out of the key groove 12.
5 is removably engaged in the drive key groove 20a of the blade holder 20. A locking portion main body 10' provided with another locking protrusion 11' having a diameter smaller than the diameter of the locking protrusion 11 is fitted into the other end of the stepped semicircular groove 9. Reference numeral 17 denotes a known vertical tool exchanging jig, with a pot 18 forming a downwardly tapered inclined wall.
A fixing key 19 is provided on the top surface of the pot 18 to be engaged with the drive key groove of the cutter holder 20, and an opening 22 into which a wrench is inserted to tighten and fix the pull stud bolt 21 of the cutter holder 20 is provided in the jig body 8. It is installed on the side wall. In the figure, 20b is a flange provided on the cutter holder 20, and 20c is a cutter holding portion.

具本体８にセツトできるのである。"Effect of the invention" Since the present invention is constructed as described above, when the flange 20b of the cutter holder 20 is fitted into the locking protrusion 11 or 11' with an uneven fit, the cutter holder 20 is fixed. Suspended stably.
Next, when the sliding key 15 is moved and fitted with the drive key groove 20a facing downward, the flange 20b is fixed and the cutter holder 20 is horizontally fixed on the jig main body 8 in a stable manner. Therefore, the pull stud bolt 21
The screw tightening and unscrewing operations can be easily performed by visually checking the screw tightening and unscrewing operations without any interference, thereby significantly improving work efficiency. Further, since the cutter tool holder 20 is not held in a vise or the like, there is no risk of damaging it, and furthermore, it is easy to set it in the jig main body 8. Furthermore, since the depth of the stepped semicircular groove 9 is sufficiently deep, even if the diameter of the cutting tool holding portion 20c of the cutting tool holder 20 is larger than the diameter of the taper shank base of the cutting tool holder 20, the tool can be fixed without interference. It can be set in the tool body 8.
