본 발명은 연삭기(Grinding Machine)에 사용되는 연삭숫돌을 일정시간 사용한후 드레싱(dressing)하는 것으로써 연삭기 자쳉 장착하여 자동으로 연삭숫돌을 드레싱 할수 있게된 연삭기 장착용 자동 드레싱 장치에 관한 것이다.The present invention relates to an automatic dressing device for a grinder that is capable of dressing a grinding wheel automatically by dressing a grinder by dressing after using a grinding wheel used in a grinding machine for a predetermined time.

종래의 경우 연삭기에서 제품을 연삭 가공하는 도중에 마모된 연삭숫돌을 드레싱 할때는 작업자가 직접 연삭숫돌을 전면에 별도로 설치된 드레서(Dresser)를 드레싱하려는 량만큼 장입하여 수동으로 연삭숫돌의 드레싱작업을 별도로 실시하는 2단계 공정으로써 드레싱 작업의 번거로움과 이때 연삭가동중이던 제품이 있을 경우는 제품을 연삭기로 부터 이탈시키고 연삭숫돌을 수동으로 드레싱작업한후 다시 제품을 안착시켜 연삭가공을 실시해야하는 여러가지 결점이 있었다.In the conventional case, when dressing a worn grinding wheel while grinding a product in a grinding machine, a worker manually loads the grinding wheel into a dressing machine installed separately to perform dressing of the grinding wheel manually. As a two-step process, the hassle of dressing work and the products that were being operated were removed from the grinding machine, the grinding wheel was manually dressed and the product was settled again.

따라서 본 발명은 이와같은 종래의 결점을 완전히 해소시키기 위해 스텝모터와 유압시린더를 이용하여 완전 자동으로 연삭기의 연삭 숫돌을 드레싱할수 있게한 새로운 발명으로써 그 기계적인 장치의 구성과 작용을 상세히 설명하면 다음과 같다.Therefore, the present invention is a new invention that allows the grinding wheel of the grinding machine to be fully automated by using a step motor and a hydraulic cylinder to completely solve such a conventional defect. As follows.

상판(1)의 상부 일측에 풀리(2)를 결착한 스텝모터(3)를 장착한 스텝모터브라켓(4)을 나사결합하여 설치하고, 상판(1)의 양측단부에 형성된 베어링하우징(5)(5')에는 커버베어링(6)(6'), 보올베어링(7)(7'), 부시(8)(8')등을 다수의 세트스크류와 소켓너트(9)로써 이송 스크류 축(10)을 양쪽에서 지지하면서 결착하고, 이송스크류축(10)의 후방인 스텝모터(3)의 풀리(2) 직하부 위치에 풀리(2')를 키이(11)로써 결착하면서 벨트(12)를 장착하고 또한 상판(1)의 전방 일측에서 드레서(13)를 고정볼트(14)로 장착한 드레서하우징(15)을 결착하여 상판(1)과 일체로된 조립체의 이송스크류축(10)에 맞물려 이송할수 있도록 너트(16)를 내장한 너트하우징(17)이 결합되어진 상태가 중앙판(18)에 나사결착하고 중앙판(18) 중앙하부에 형성된 시린더로드브라켓(19)에는 유압시린더(20)의 로드(21)를 결착한 중앙 판(18) 은 유압시린더(20)가 장착되고 연삭기몸체(22)에 나사결합된 베이스프레임(23)과 좌우 슬라이딩 할수 있도록 결합되어진 구성으로써 미설명부호 24는 연삭숫돌인 것이다.A bearing housing (5) formed at both ends of the upper plate (1) by screwing the step motor bracket (4) mounted with the step motor (3) to which the pulley (2) is attached to the upper side of the upper plate (1). (5 ') includes a cover bearing (6) (6'), a bowl bearing (7) (7 '), a bush (8) (8'), and the like by using a plurality of set screws and socket nuts (9). 10) is supported by both sides, and the belt 12 is engaged with the pulley 2 'by the key 11 at the position directly below the pulley 2 of the step motor 3, which is the rear of the transfer screw shaft 10. To the transfer screw shaft 10 of the assembly integrated with the top plate 1 by attaching the dresser housing 15 to which the dresser 13 is mounted on the front side of the top plate 1 with the fixing bolts 14. The state in which the nut housing 17 having the nut 16 embedded therein is coupled to the center plate 18 and the cylinder rod bracket 19 formed at the center lower part of the center plate 18 is coupled to the hydraulic cylinder. 20 loads The center plate 18 to which the 21 is attached is mounted to the hydraulic cylinder 20 and coupled to the base frame 23 screwed to the grinding machine body 22 so as to slide left and right. It is a whetstone.

상기와 같이 상판(1)의 전체적인 조립체가 중앙판(18)의 조립체에 결착되고 그 중앙판(18)의 조립체는 연삭기 몸체(22)에 결합된 베이스 프레임(23)에 슬라이딩할수 있도록 하게 결합된 주요 3부분으로된 본 발명의 그 작용을 상세히 설명하면 다음과 같다.As described above, the entire assembly of the upper plate 1 is fastened to the assembly of the middle plate 18 and the assembly of the middle plate 18 is slidably coupled to the base frame 23 coupled to the grinder body 22. Referring to the operation of the present invention in three main parts as follows.

연삭기에 장착된 연삭숫돌(24)의 후방에 본 발명의 장치인 베이스페임(23)을 연삭기몸체(22)의 일부위에 장착하여 작업자의 임의대로 제품을 연삭가공도중이나 혹은 가공이 끝난후에 즉, 제품의 가공상태에 무관한 임의의 시기에 연삭숫돌(24)을 드레싱하려할때 본 발명인 드레싱장치의 전원스위치를 조작시키면 스텝모터브라켓(4)을 이용하여 상판(1)에 결착된 스텝모터(3)의 특성에 따라 인정회전수만큼 구동하며 그 구동력은 풀리(2)에 장착된 벨트(12)에 의해 이송스크류축(10)에 장착된 풀리(2')로 동력전달되면 상판(1)이 하부 양측 베어링하우징(5)(5')과 커버베어링(6)(6'), 보올베어링(7)(7'), 부시(8)(8')등으로 지지하며 결합된 이송스크류축(10)과 풀리(2')가 일체로 키이(11)에 의해 결합되여 있기 때문에 이송스크류축(10)은 스텝모터(3)의 회전수만큼 회전하게되며 이때 이송스크류축(10)에는 중앙판(18)에 너트하우징(17)으로 결착하여 설치된 너트(16)가 맞물려있기 때문에 이송스크류축(10)의 회전에 의해 전방 방향인 A방향으로 전진이동하게 된다.After the grinding wheel 24 mounted on the grinding machine, the base frame 23, which is the device of the present invention, is mounted on a part of the grinding machine body 22, so that the product can be arbitrarily processed by the operator or after finishing the processing. If you operate the power switch of the dressing device of the present invention when dressing the grinding wheel 24 at any time irrespective of the processing state of the product, the step motor which is bound to the upper plate 1 using the step motor bracket 4 According to the characteristics of 3), the driving speed is driven by the authorized rotation speed, and the driving force is transferred to the pulley 2 'mounted on the feed screw shaft 10 by the belt 12 mounted on the pulley 2, and the upper plate 1 Transfer screw shafts supported by the lower bearing housings 5, 5 ', cover bearings 6, 6', ball bearings 7, 7 ', bushes 8, 8' and the like. Since the 10 and the pulley 2 'are integrally coupled by the key 11, the feed screw shaft 10 is rotated by the rotational speed of the step motor 3. At this time, since the nut 16 is attached to the feed screw shaft 10 by the nut housing 17 on the center plate 18, the feed screw shaft 10 moves forward in the A direction, which is forward by rotation of the feed screw shaft 10. Done.

이때 이송스크류축(10)에는 상판(1) 상부의 조립체와 일측에 드레서하우징(15)에 드레서(13)가 고정볼트(14)로 고정된 전체의 일체로된 조립체인 것으로써 제1도에서 보는 바와 같이 이송스크류축(10)과 동시에 전방인 A방향으로 이동하는 것이며 이는 즉, 드레서(13)의 단부가 일정한 드레싱하려는 량만큼 진행한 상태로 됨과 동시에 베이스프레임(23)에 장착된 유압시린더(20)의 작동에 의해 로드(21)는 제3도에서 보느 바와같이 B방향으로 진행함에 따라 시린더로드브라켓(19)과 일체로된 중앙판(18)과 그 상부에 결착된 너트 하우징(17)의 너트(16) 및 이와 결합된 상판(1)의 전체적인 조립체는 베이스프레임(23)의 안내를 받아 진행하게 되어 동작 완료되는 것으로써 즉, 스텝모터(3)의 구동력에 의해 드레서(13)는 A방향으로 전진하게 되어 임의의 드레싱하려는 연삭숫돌(24)의 드레싱량만큼 조절하여 전진시키고 제2단계 동작인 유압시린더(20)의 작동에 의해 베이스프레임(23)의 안내를 받아 B방향으로 진행하면서 연삭숫돌(24)을 드레서(13)에 의해 드레싱되는 동작을 하게 되는 것으로써 완전자동으로 연삭숫돌(24)의 드레싱을 할수 있게되어 종래의 여러가지면에서 번거로운 결점을 완전 해소하게 되고 또한 이러한 자동에 의한 드레싱장치는 전혀없는 상태이며 특히 연상기 자체에 부착된 자동드레싱장치는 새로이 발명되어진 것이다.At this time, in the conveying screw shaft 10, the assembly of the upper plate 1 and the dresser 13 is fixed to the dresser housing 15 on one side, and the entire assembly is fixed to the fixing bolt 14. As can be seen, the feed screw shaft 10 is moved forward in the direction A, that is, the end of the dresser 13 is in a state in which it proceeds by a certain amount of dressing, and at the same time the hydraulic cylinder mounted to the base frame 23 As the rod 20 is driven by the operation of the rod 20, as shown in FIG. 3, the rod 21 moves toward the B direction, and the nut housing fastened to the center plate 18 integral with the cylinder rod bracket 19 and the upper portion thereof. The entire assembly of the nut 16 of the 17 and the upper plate 1 coupled thereto is driven by the guide of the base frame 23 to complete the operation, that is, by the driving force of the step motor 3. 13) is advancing in the A direction for any dressing to grinding The grinding wheel 24 is drier 13 by adjusting the dressing amount of the stone 24 to advance and proceeding in the direction B by receiving the guide of the base frame 23 by the operation of the hydraulic cylinder 20 which is the second step operation. The dressing operation of the grinding wheel 24 can be done automatically by dressing by), which completely eliminates troublesome defects in various aspects of the related art. The automatic dressing device attached to the retarder itself is a new invention.
