本考案は、ドリル等の切削機械のドリルアーバ
ーからドリルチヤツクを簡単に取り外すことので
きるチヤツク取り外し具に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a chuck removal tool that can easily remove a drill chuck from a drill arbor of a cutting machine such as a drill.

ていた。
Conventionally, for example, in order to remove a drill chuck from a drill arbor, the drill chuck was removed by hammering the end face of the drill chuck, or a wedge plate was driven into the groove formed between the end face on the drill chuck side and the connecting part on the drill arbor side. Then, the wedge slope of the wedge plate presses the end face of the drill chuck to loosen the drill chuck and remove it.
しかし、従来法によると槌打する力及び槌打す

However, according to the conventional method, the hammering force and hammering angle are irregular, and the wedge slope is not perpendicular to the axial direction of the drill arbor, so the force is applied at the moment the drill chuck comes out of the drill arbor. Since the direction does not match the axial direction, an unreasonable force will be applied to the drill arbor.
添付図面を参照して本考案の要旨を説明する。 The gist of the present invention will be explained with reference to the accompanying drawings.

ツク取り外し具に係るものである。 The drill chuck 1 is removed from the taper shaft 9 of the drill arbor 2 by driving the drill chuck 1 between the end surface 2' of the main body of the drill arbor 2, on which the taper shaft 9 is protruded, and the end surface 1' of the drill chuck 1. is a horizontal surface, the lower surface 3b is a wedge slope, and the side surface 3c on the base side is a flat hitting surface,
A wedge plate 3 is provided with a guide groove 6 having a width approximately equal to the diameter of the tapered shaft 9 at its tip, a lower surface 5a is a horizontal surface, an upper surface 5b is a wedge slope having the same slope as the wedge slope, and the guide groove 6 is provided at the tip. This relates to a chuck removal tool comprising a wedge receiving plate 5 provided with a guide groove 4 that matches the chuck.

てくことになる。[Operation] To explain based on the embodiment, as shown in the figure, the guide groove 4 of the wedge receiving plate 5 is fitted into the connecting part 7 of the drill chuck 1 and the drill arbor 2, the wedge receiving plate 5 is inserted, and the wedge receiving plate 5 is inserted. Similarly, the wedge plate 3 is fitted onto the connecting portion 7 using the guide groove 6 so as to face the plate 5 and rub against the wedge receiving plate 5, and the two are overlapped, and the side surface 3c of the wedge plate 3 is fitted. For example, when hit with a hammer 8, the wedge plate 3 is guided by the guide groove 6 and approaches the wedge receiving plate 5 while rubbing against the wedge receiving plate 5.

からスムースに外れることになる。 At this time, according to the wedge principle, the hammering force is applied to the end surface 2' of the chuck arbor 2 and the end surface 1' of the drill chuck 1 in the axial direction of the tapered shaft 9 via the wedge plate 3 and the wedge receiving plate 5.
Therefore, the drill chuck 1 is connected to the chuck arbor 2.
It will come off smoothly.

As shown in FIG. 3, when the inner circumferential surface 11 of the guide grooves 4 and 6 of the wedge plate 3 and the wedge receiving plate 5 is made into a tapered slope, this inner circumferential surface 11 and the outer circumferential surface 10 of the tapered shaft 9 match. It becomes a more efficient removal tool.
図面のクサビ板３とクサビ受板５は同形のもの
を採用した場合を図示している。 The wedge plate 3 and the wedge receiving plate 5 in the drawings are of the same shape.
図中符号５ｃは打撃面である。 The reference numeral 5c in the figure is a striking surface.
