Description

本考案は、コレットと関連があり、特に、弾性のあるコレットに関係がある。 The present invention relates to a collet, and in particular to an elastic collet.

一般に、弾性のあるコレットは、刃具上半部を入れる軸孔の孔径の大小に多くの規格があり、製作過程において便利に素早く生産するため、通常、軸孔に対して２段階の製作方式が採られていて、図１に示す如く、まず、大きな孔径を加工して、前部分軸孔１とし、後に続けて実際に必要な孔径を加工し、以って、完成して後部分軸孔２となる。 In general, an elastic collet has many standards for the diameter of the shaft hole into which the upper half of the cutting tool is inserted, and is usually produced in a convenient manner and quickly in the manufacturing process. As shown in FIG. 1, first, a large hole diameter is processed to form the front partial shaft hole 1, and subsequently the actual required hole diameter is processed to complete the rear partial shaft hole. 2.

しかしながら、挟み持つ刃具のコレットの筒身がきつめに刃具を挟む際、前部分軸孔１と後部分軸孔２との孔径寸法の差は比較的大きくなり、前部分軸孔１はコレットがきつく締められる時、容易に比較的大きな変形量を産み出し、コレットに於いて何度も反復してきつく締めまたは緩めた後、最初の変形量の最も大きな前部分軸孔が１回原状に戻る影響を受け、遂に間接的に後部分軸孔２の孔径は変動を受けて元の寸法精度を喪失する問題が発生し、後者の刃具を再び挟み持って使用することで言えば、不安定な欠点を産み出す状況となる。 However, when the barrel of the collet of the bladed tool that is pinched sandwiches the blade tightly, the difference in hole diameter between the front partial shaft hole 1 and the rear partial shaft hole 2 becomes relatively large, and the front partial shaft hole 1 is tightly colleted. When tightened, it easily produces a relatively large amount of deformation, and after repeatedly tightening or loosening the collet repeatedly, the front shaft hole with the largest initial amount of deformation will return to its original shape once. As a result, there is a problem that the hole diameter of the rear partial shaft hole 2 is changed indirectly and the original dimensional accuracy is lost. If the latter blade tool is sandwiched and used again, an unstable defect is caused. It becomes the situation to produce.

故に、従来の弾性のあるコレットで言えば、従来の設計構造の影響は刃具の挟み持つ精度の正確さに達し、実際の加工精度に影響する。これを鑑み、本考案の創作者は、詳細な思索を経て、並びに長年関連業界に従事して研究開発経験を積み、ついに本考案を産み出した。 Therefore, in the case of the conventional elastic collet, the influence of the conventional design structure reaches the accuracy of the accuracy of the cutting tool and affects the actual machining accuracy. In view of this, the creator of the present invention, after careful thought, and engaged in related industries for many years, gained research and development experience and finally produced the present invention.

即ち、本考案の主要な目的は、一種の弾性のあるコレットを提供することにあり、軸孔は容易に変形を発生することはなく、安定して刃具を挟み、使用する効果を有している。 That is, the main purpose of the present invention is to provide a kind of elastic collet, the shaft hole does not easily deform, and has the effect of stably sandwiching and using the blade. Yes.

上述の目的を達成するため、本考案が提供する一種の弾性のあるコレットは、一つの本体を有し、本体の両端はそれぞれ一つの頂面及び一つの底面を有し、一つの軸孔は本体の軸心に沿って頂面と底面を貫通している。いくつかの剖溝が本体の側面に設置されている。その特徴は、以下である。軸孔は頂面の前部分近くに一つの比較的大きな孔径の第一の真っ直ぐな孔を有し、軸孔は底面の後部分近くに一つの比較的小さな孔径の第二の真っ直ぐな孔を有し、第一の真っ直ぐな孔の孔径と第二の真っ直ぐな孔の孔径との差の値は０．５ｍｍと等しいか或いは小さい。 In order to achieve the above object, the elastic collet provided by the present invention has one body, both ends of the body each have one top surface and one bottom surface, and one shaft hole has It penetrates the top and bottom surfaces along the axis of the main body. Several autopsy grooves are located on the sides of the body. Its characteristics are as follows. The shaft hole has a first straight hole with one relatively large hole diameter near the front portion of the top surface, and the shaft hole has a second straight hole with one relatively small hole diameter near the rear portion of the bottom surface. And the difference between the hole diameter of the first straight hole and the hole diameter of the second straight hole is equal to or smaller than 0.5 mm.

図２から図５を示すところをご覧ください。本考案の比較的優れた一実施例の提供する一種の弾性のあるコレットは、一つの本体１０を有し、本体１０の両端はそれぞれ一つの頂面１１及び一つの底面１２となっている。一つの軸孔１３は本体１０の中心を貫くように設置されていて、軸孔１３は本体１０の頂面１１と底面１２を貫通していて、軸孔１３は２段階の設計になっている。軸孔１３は頂面１１の前部分に一つの比較的大きな孔径の第一の真っ直ぐな孔１３１を有していて、軸孔１３は底面１２に近づく後部分に一つの比較的小さな孔径の第二の真っ直ぐな孔１３２を有していて、且つ第一の真っ直ぐな孔１３１と第二の真っ直ぐな孔１３２との孔径の差の値は０．５ｍｍと等しいか或いは小さい。本体１０は頂面１１に近づく部分で一つの円錐状の被せ合わせ部分１４となっていて、ちょうど工作機械のアーバの軸孔内（図中未表示）に収まることができる。被せ合わせ部分１４の下方は一つの首の締まった首軸１５になっていて、首軸１５の下方は一つの挟み持ち部分となり、工作刃具の刃柄（図中未表示）を底面１２より軸孔１３の第二の真っ直ぐな孔１３２の中に入れることができる。本体１０は体側に数個の第一剖溝１７及び数個の第二剖溝１８を有していて、それらの剖溝１７と剖溝１８は軸に沿って交錯して開設されていて、本体１０は挟み持つ力を発揮することができる。 Please refer to Figure 2 to Figure 5. A kind of elastic collet provided by a relatively superior embodiment of the present invention has a main body 10, and both ends of the main body 10 have a top surface 11 and a bottom surface 12, respectively. One shaft hole 13 is installed so as to penetrate the center of the main body 10, and the shaft hole 13 passes through the top surface 11 and the bottom surface 12 of the main body 10, and the shaft hole 13 has a two-stage design. . The shaft hole 13 has a first straight hole 131 having a relatively large hole diameter in the front portion of the top surface 11, and the shaft hole 13 has a relatively small hole diameter in the rear portion approaching the bottom surface 12. The first straight hole 131 and the second straight hole 132 have a hole diameter difference value equal to or smaller than 0.5 mm. The main body 10 is formed as a conical covering portion 14 at a portion close to the top surface 11 and can be accommodated in a shaft hole (not shown in the drawing) of the arbor of the machine tool. Below the covering portion 14 is a neck 15 with one neck tightened, and below the neck 15 is a pinching portion, and the handle of the work tool (not shown in the drawing) is pivoted from the bottom surface 12. It can enter into the second straight hole 132 of the hole 13. The main body 10 has several first autopsy grooves 17 and several second autopsy grooves 18 on the body side, and these autopsy grooves 17 and autopsy grooves 18 are opened along the axis, The main body 10 can exhibit the force of pinching.

本実施例の長所は、軸孔１３の２段階の孔径の差の値は０．５ｍｍより小さいか或いは等しく、しっかりと挟み持つ際の応力が連続しない現象が小さく、軸孔１３は変形偏移し難く、軸線は工作機械の主軸の軸線に偏移し、これにより、刃具が挟み持たれた後、中心の軸線は確実に主軸の軸線と重なり合い、偏移或いは傾斜現象を生み出すことはなく、加工過程に於いて振動を発生させて加工精度を低下させ、工作機械及び加工ワークを損壊させることがない。 The advantage of this embodiment is that the difference between the two hole diameters of the shaft hole 13 is less than or equal to 0.5 mm, and the phenomenon that the stress does not continue when holding firmly is small. However, the axis is shifted to the axis of the main axis of the machine tool, so that after the cutting tool is sandwiched, the central axis does not overlap with the axis of the main axis without causing a shift or tilt phenomenon. In the machining process, vibrations are not generated to reduce machining accuracy, and the machine tool and workpiece are not damaged.
