본 고안은 공작기계에서 소형공작물을 가공함에 있어서 공작물을 지지하여 주는 지그(JIG)인 돌리개를 공작기계주축대의 프론트커버(FRONT COVER)에 직접 볼트로 체결하여 보다 편리하고 안정되게 가공할 수 있도록한 공작기계의 공작물지지장치에 관한 것이다.The present invention is designed to make machining more convenient and stable by fastening the dolly, which is a jig supporting the workpiece, directly to the front cover of the machine tool headstock when machining small workpieces in machine tools. It relates to a workpiece support device of a machine tool.
일반적으로 선반등의 공작기계에서 소형공작물을 가공함에 있어서는, 첨부도면 제1도에 도시한 바와같이 주축대(10)내부에 센터지지봉(11)을 장착하고 상기 센터지지봉(11)에 가공하고자 하는 공작물(100)의 일측면을 밀착시킨후, 상기 주축대(10)와 대응하도록 구성된 심압대(20)의 심압봉(21)으로 공작물(100)의 타단을 압압하여 고정하되, 상기 주축대(10)의 프론트커버(12)와 드라이빙암(13)으로 결합된 별도의 지그인 돌리개(14)를 이용하여 공작물을 지지하여 돌려주도록 구성하였다.In general, in the machining of small workpieces in machine tools such as lathes, as shown in FIG. 1 of the accompanying drawings, a center support rod 11 is mounted inside the headstock 10 and the center support rod 11 is to be processed. After closely contacting one side of the work piece 100, the other end of the work piece 100 is pressed and fixed with the tailstock bar 21 of the tailstock 20 configured to correspond to the headstock 10, and the headstock ( It was configured to support and turn the workpiece by using a separate jig dolly 14 coupled to the front cover 12 and the driving arm 13 of 10).
즉 이와같은 종래의 구성은 공작물(100)을 채우기 위해 돌리개(14)의 볼트(14a)를 풀어 공작물(100)을 돌리개(14)에 물리고, 당시 볼트(14a)를 죄어서 공작물(100)이 헛돌지 않게 조인상태로 주축대(10)의 센터지지봉(11)과 심압대(20)의 심압봉(21)으로 공작물(100)을 압압지지토록한 다음, 돌리개(14) 돌출부의 요홈(14b)에 주축대(10)의 프론트커버(12)에 셀팅된 드라이빙암(13)을 걸어서 가공한다.In other words, such a conventional configuration is to loosen the bolt 14a of the dolly 14 to fill the work 100, the work 100 is bitten on the dolly 14, the bolt (100a) at the time to tighten the workpiece 100 is The workpiece 100 is pressed against the center support rod 11 of the headstock 10 and the tailstock 21 of the tailstock 20 in a tightly tightened state, and then the groove 14b of the protrusion 14 of the dolly 14 is pressed. ) Is processed by hanging the driving arm 13 selected on the front cover 12 of the main shaft (10).
그러나 상기한 지금까지의 구성은 공작물을 고정하기 위하여 돌리개(14)의 볼트(14a)를 수시로 조작하여야 하므로 작업이 번거롭고 작업중 볼트(14a)가 풀릴 경우 공작물(100)이 이탈되면서 안전사고를 유발할 우려가 있었으며, 특히 가공하고자 하는 공작물이 단부에 세레이션(SERRATION)을 형성하고 폭이 작은 경우에는, 돌리개를 채울수 있는 공간이 작아 작업중 공작물이 이탈할 염려가 있는 것은 물론, 공작물의 세레이션부가 손상될 염려가 있었다.However, the above-described configuration requires frequent operation of the bolt 14a of the dolly 14 to fix the work, which is cumbersome, and if the bolt 14a is released during work, the work 100 may be detached and cause a safety accident. Particularly, when the workpiece to be processed forms serrations at the end and the width is small, the space for filling the dolly is small, which may cause the workpiece to escape during operation, and the serration of the workpiece may be damaged. There was concern.
본고안은 상기한 지금까지의 제결함을 감안하여 공작기계주축대의 프론트커버전면에 워커홀더를 나사결합하고, 상기 워커홀더에 내주면에 다수의 요홈을 환설한 돌리개를 설치하여서 상기 돌리개가 공작물의 쎄레이션부를 감착지지하도록 함으로써, 공작물을 보호하고 보다 안정된 지지상태로 가공이 이루어짐은 물론, 공작물을 로딩 또는 언로딩하는데 소요되는 시간을 절감하여 작업능률을 향상시키도록함에 그 목적을 둔 것이다.In view of the above deficiencies mentioned above, this work screw-couples the worker holder to the front cover of the machine tool spindle, and installs a turner having a plurality of grooves on the inner circumferential surface of the work holder so that the turner is secured to the workpiece. It is intended to improve the work efficiency by reducing the time required for loading and unloading the workpiece as well as protecting the workpiece and processing the workpiece to a more stable support state.
상기한 목적을 달성하기 위한 본고안은 중앙에 센터지지봉이 삽설되는 프론트커버전면에 워커홀더(WORK HOLDER)를 나사결합하고, 상기 워커홀드의 선단돌출부 끝단에는 내주면에 요홈을 환설한 공작 물지지용돌리개를 센터지지봉의 끝단보다 돌출되도록 나사결합하여 공작물의 일측단외연을 감착지지토록 구성한 것으로 이를 첨부도면에 의거 더욱 상세히 설명하면 다음과 같다.In order to achieve the above object, the present invention has a work holder screwed to a front cover front surface in which a center support rod is inserted in the center, and the end of the tip of the walker holder is provided with a recess for the work support. Is screwed so as to protrude from the end of the center support rod is configured to support the one end edge of the workpiece as described below in more detail based on the accompanying drawings.
첨부도면 제2도에 도시한 바와같이 주축대(10)와 심압대(20) 공구대(30)로 구성되는 공작기계에 있어서,In the machine tool consisting of the main shaft 10 and the tailstock 20, the tool post 30, as shown in FIG.
상기 주축대(10)의 프론트커버(12)전면에는 중앙에 돌출부(51)를 갖는 워커홀더(50)를 볼트(50)로 체결하여 일체로 결합하고, 상기 워커홀더(50)의 돌출부(52)로 체결하여 일체로 결합하고, 상기 워커홀더(50)의 돌출부(51)전면에는 내주면에 다수의 요홈(56)을 환설한 공작물파지공(57)을 형성한 돌리개(55)를 볼트(52)로 체결하되, 상기 돌리개(55)는 주축대(10)에 장착된 센터지지봉(11)의 선단보다 돌출되게 구성한다.The front of the front cover 12 of the headstock 10 is fastened to the front of the worker holder 50 having a protrusion 51 in the center by bolts 50 to be integrally coupled, the protrusion 52 of the worker holder 50 Bolts 52 to form a workpiece gripping hole 57 formed by turning a plurality of grooves 56 on the inner circumferential surface on the front surface of the protrusion 51 of the worker holder 50. The fastener 55 is configured to protrude from the distal end of the center support rod 11 mounted on the headstock 10.
상기한 본고안은 일측단부에 세레이션부를 형성한 일정한 치수의 공작물(100)을 가공함에 있어서, 상기 심압대(20)를 후퇴시킨다음 공작물(100)의 세레이션부를 상기 주축대(10)의 프론트커버(12)에 장착된 워커홀더(50)의 돌리개(55)에 형성한 공작물파지공(57)에 삽착하여 주축대(10)의 센터지지봉(11)에 일측단부를 밀착하고, 타단을 심압대(20)의 심압봉(21)으로 밀착고정한 다음, 주축대(10)를 회동시키면서 공구대(30)에 장착된 공구로 가공을 하면된다.In the above-described proposal, in processing the work piece 100 having a constant dimension in which a serration part is formed at one end, the tail stock 20 is retracted, and then the serration part of the work piece 100 of the headstock 10 Inserted into the workpiece gripping hole 57 formed in the dolly 55 of the worker holder 50 mounted on the front cover 12, one end is in close contact with the center support rod 11 of the headstock 10, the other end After tightly fixing the tailstock 21 of the tailstock 20, the headstock 10 may be rotated to process the tool mounted on the tool post 30.
상기한 본고안은 공작물을 가공하기위한 로딩작업과 가공된 공작물의 언로딩작업을 수행함에 있어서, 단순히 돌리개의 공작물파지공에 삽입 또는 이탈시키기만 하면되므로 이때 소요되는 작업시간을 절감하게되고 공작물에 가공된 세레이션부를 보호함은 물론, 돌리개가 공작물을 감착한 상태가 되므로써 작업도중 공작물이 이탈될 염려가 없는등 매우 안전하고 편리하게 작업을 수행할 수 있는 신규하고도 유용한 고안이다.In the above-mentioned proposal, in carrying out the loading operation and the unloading of the processed workpiece for machining the workpiece, simply inserting or removing the workpiece into the dolly workpiece gripping hole reduces work time required for the workpiece. As well as protecting the processed serrations, it is a new and useful design that can perform the work very safely and conveniently, such that there is no fear that the workpiece is detached during the work, since the dolly is in a state where the work is attached.
