종래 이런 종류의 공작기계는 제1도에 예시한 레이저 가공기와 같이 레이저 빔을 방사하는 헤드부(2)는 기체(1) 일측에 고정하고, 타측에 전후 좌우로 왕복 이동가능한 왕복대(3)의 파지구(4)에 공작물(WP)의 일측연부를 파지하여 다수의 공작물 지지볼(5)(6)이 돌출된 중앙의 고정테이블(7)과 양측 왕복테이블(8) 상에서 공작물(WP)을 이동시키면서 가공하도록 되어 있다.In the conventional machine tool of this kind, the head part 2 that emits a laser beam, such as the laser processing machine illustrated in FIG. One side edge of the workpiece WP is held in the holding hole 4 of the workpiece WP on both the fixed table 7 and the reciprocating table 8 at the center where the plurality of workpiece support balls 5 and 6 protrude. It is to be processed while moving.

그러나 왕복대(3)의 파지구(4)의 하부파지 각(4')은 지지볼(5)(6)에 의해 지지되는 공작물(WP)의 하부에 위치하므로 파지구(4)의 공작물 파지위치가 왕복테이블(8)상에 있을 경우에는 상관이 없으나 고정테이블(7)상의 볼(5)와 동일선상에 있을 경우에는 왕복대(3)가 헤드부(2) 방향으로 이동시 파지구(4)의 하부파지각(4')의 선단이 지지볼(5)에 충돌하게 되어 가공작업이 중지되거나 기능고장을 일으키며 파손될 염려가 있으므로 파지구(4)를 항상 볼과 볼사이에 위치하도록 해야 하며 볼의 돌출높이가 고정되어 있으므로 공작물에 따른 볼돌출높이를 조정할 수 없다.However, the lower grip angle 4 ′ of the gripper 4 of the carriage 3 is located below the workpiece WP supported by the support balls 5, 6, so that the workpiece grip of the gripper 4 is gripped. It does not matter if the position is on the reciprocating table 8, but when the position of the carriage 3 moves in the direction of the head 2 when the reciprocating table 3 is in the same line as the ball 5 on the fixed table 7 Since the tip of the lower gripping angle 4 'of the c) collides with the support ball 5, the machining operation may be stopped or cause malfunction, and the gripping opening 4 should always be located between the ball and the ball. Since the protrusion height of the ball is fixed, it is impossible to adjust the ball protrusion height according to the workpiece.

따라서 공작물(WP)의 크기에 따른 적절한 파지가 곤란하며 공작물 파지 작업이 번잡하게 되는 등 많은 폐단이 있었다.Therefore, it is difficult to properly grasp according to the size of the workpiece (WP) and there are many closures, such as complicated work of gripping the workpiece.

따라서 본 고안은 이러한 종래의 제반 문제점을 해소하기 위하여 일측에는 공작물 파지구가 설치된 왕복대를 설치하고 타측에는 헤드부를 고정설치한 기체 중앙부에 다수 공작물 지지볼이 설치된 고정 테이블을 설치하여서 된 통상의 공작기계에 있어서, 상기 공작물 지지볼이 좌우 방향 일열씩 식설된 다수의 볼 고정 승강판을 테이블판에 하향 입설된 안내봉에 지지하여 상시 상승되도록 탄설하고, 승강판 양측단에는 로울러가 지지된 브라켓트를 고정하고, 왕복대 하부에는 경사면의 하단이 적어도 파지구 하부파지각의 선단과 동일 수직 선상에 위치하는 도그판을 고정하여서 되며, 또한 브라켓트 상부에는 테이블판 저면에 두부가 당접되는 볼돌출 높이 조절나사를 조절 가능하게 나입한 것이다.Therefore, the present invention is to solve the conventional problems, one side is provided with a carriage is provided with a workpiece holding hole, and the other side is a normal work by installing a fixed table installed a plurality of workpiece support ball in the center of the body fixed to the head portion In the machine, the workpiece support ball is supported by a guide rod installed downward on the table plate, and a plurality of ball fixed lifting plates planted one by one in the left and right directions are mounted so that they are always raised, and brackets on which rollers are supported are provided at both ends of the lifting plate. In the lower part of the carriage, the lower end of the inclined surface is fixed at least with the dog plate positioned at the same vertical line as the tip of the lower holding angle of the gripper. Also, the upper part of the bracket has a ball protrusion height adjusting screw that contacts the head to the bottom of the table plate. The mouth is adjustable.

이하 본 고안을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도면에 있어서 (10)은 고정테이블(7)에 설치되는 공작물 지지볼(5)을 좌우 방향 일열씩 식설한 볼고정 승강판으로써 전후 방향으로 다수(도면에서는 5개) 배열되어 있다.In the drawing, reference numeral 10 denotes a ball fixing lifting plate in which the work support balls 5 installed on the fixed table 7 are planted one by one in a left and right direction, and are arranged in a large number (five in the figure) in the front-rear direction.

볼 고정 승강판(10)은 고정테이블(7)의 테이블판(11)에 하향 입설된 좌우 한쌍의 안내봉(21)에 승강 가능하게 지지되어 있으며 안내봉(12)에 감삽된 스프링(13)에 의해 상시 상승되어 볼(5)이 테이블판(11) 상방으로 돌출되도록 되어 있다.The ball fixed elevating plate 10 is supported by a pair of left and right guide rods 21 which are placed on the table plate 11 of the fixed table 7 so as to be lifted and lowered. As a result, the ball 5 is projected upward above the table plate 11.

승강판(10)의 양단에는 로울러(14)가 설치된 브라켓트(10)가 고정되어 있다.Brackets 10 provided with rollers 14 are fixed to both ends of the elevating plate 10.

왕복대(3)의 하부에는 경사면(16)을 보유하는 한쌍의 도그판(17)이 설치되어 있다.The lower part of the carriage 3 is provided with a pair of dog plates 17 which hold the inclined surface 16.

도그판(17)은 경사면(16)의 하단(16')이 공작물 파지구(4)의 하부 파지각(4') 선단과 적어도 동일 수직선상에 위치하도록 하며 그 수직선보다 헤드부(2) 쪽으로 위치하는 것은 상관없으나, 그 반대쪽 즉 왕복대(3)의 후방측에 위치하면 안된다.The dog plate 17 is positioned so that the lower end 16 'of the inclined surface 16 is at least on the same vertical line as the tip of the lower gripping angle 4' of the workpiece gripper 4, and toward the head 2 than the vertical line. It does not matter, but it should not be located on the opposite side, that is, on the rear side of the carriage 3.

또한 승강판(10)의 양측단에 고정된 브라켓트(15) 상부에는 테이블판(11) 저면에 두부가 당접되는 볼돌출 높이 조절나사(18)가 조절 가능하게 설치되어 있다.In addition, the upper part of the bracket 15 fixed to both ends of the elevating plate 10 is provided with a ball projection height adjustment screw 18, the head of the head abuts on the bottom of the table plate 11 adjustable.

이러한 구성의 본 고안은 파지구(4)에 공작물(WP)을 고정한 상태에서 왕복대(3)가 헤드부(2) 측으로 이동하여 왕복대(3) 하부에 설치된 도그판(17)이 전진하면서 승강판(10) 양측에 이르면 경사면(16)이 양측 로울러(4) 상부에 당접하게 되고 계속하여 이동되면 로울러(14)는 경사면(16)에 의해 압압되며 이때 승강판(10)이 하강하여 볼(5)은 테이블판(11)에서 몰입하기 시작한다.According to the present invention of the above configuration, while the workpiece WP is fixed to the gripper 4, the carriage 3 moves to the head 2 side, and the dog plate 17 installed under the carriage 3 moves forward. When the lifting plate 10 reaches both sides, the inclined surface 16 abuts on the upper sides of the rollers 4 and continues to move, and the roller 14 is pressed by the inclined surface 16. At this time, the lifting plate 10 is lowered and viewed. (5) starts to immerse in the table board 11. As shown in FIG.

로울러(14) 상부에 경사면(16)의 하단(16')이 접촉되면 승강판(10)은 하한 위치까지 하강되며 이에 따라 볼(5)은 완전히 몰입된다. 따라서 파지구(4)가 볼(5)과 전후 방향의 동일선상에 위치하드라도 하부파지 각 (4')이 볼(5)에 충돌할 염려가 없으므로 안전사고 등을 미연에 방지할 수 있다.When the lower end 16 ′ of the inclined surface 16 is in contact with the upper portion of the roller 14, the lifting plate 10 is lowered to the lower limit position, and thus the ball 5 is completely immersed. Therefore, even if the gripper 4 is located on the same line as the ball 5, the lower grip angle 4 'may not collide with the ball 5, thereby preventing safety accidents.

또한 볼(5)가 완전히 몰입된 상태에서는 그 부위의 공작물(WP)은 파지구(4)에 의해 지지되어 있으므로 공작물 지지에는 아무런 문제도 없게 된다. 다음 왕복대(3)가 후진하여 도그(17)의 경사면(16)이 하단(16')으로부터 선단쪽으로 로울러(14)와의 접촉점이 이동하므로 승강판(10)은 스프링(13)에 의해 압상되고 볼(5)은 테이블판(11) 상으로 돌출되어 공작물(WP)을 지지하게 된다.In addition, since the workpiece | work WP of the site | part is supported by the holding | gripping tool 4 in the state in which the ball 5 was fully immersed, there will be no problem in workpiece support. As the next carriage 3 moves backward, the inclined surface 16 of the dog 17 moves the contact point with the roller 14 from the lower end 16 'toward the tip, so that the elevating plate 10 is pushed up by the spring 13. The ball 5 protrudes onto the table plate 11 to support the work WP.

또한 승강판(10)의 양측단에 고정된 브라켓트(15) 상부에는 테이블판(11) 저면에 두부가 당접되는 조절나사(18)를 회전시키는 것에 의해 테이블판(11)의 저면과 승강판(10)을 승강시키므로써 테이블판(11) 상부로 돌출되는 볼(5)의 높이를 공작물(WP)의 조건에 따라서 적정 높이로 조정할 수 있다.In addition, the bottom of the table plate 11 and the elevating plate (by rotating the adjusting screw 18, the head of which is abutted on the bottom of the table plate 11, on the upper portion of the bracket 15 fixed to both ends of the elevating plate 10 ( By elevating 10), the height of the ball 5 protruding upward from the table plate 11 can be adjusted to an appropriate height in accordance with the condition of the work WP.

이상과 같이 본 고안에 의하면 공작물 파지구가 고정테이블의 볼과 동일 선상에 위치하드라도 파지구 선단 선상에 볼이 위치하면 몰입되도록 하였으므로 파지구 하부 파지각이 볼에 충돌하는 일이 없게되어 기능 고장이나 파손등의 사고를 미연에 방지할 수 있으며, 파지구의 공작물 파지 위치에 하등 제한을 받지 않으므로 공작물 셋팅파지 작업이 신속하고 용이하게 되며 볼의 돌출높이를 조절할 수 있으므로 공작물과 가공조건에 따라 적절하게 사용할 수 있는 효과가 있다.As described above, according to the present invention, even if the workpiece gripper is positioned on the same line as the ball of the fixed table, the ball is immersed when the ball is positioned on the tip of the gripper so that the grip angle below the gripper does not collide with the ball, thereby causing a malfunction. It is possible to prevent accidents or damages in advance, and because there is no restriction on the gripping position of the workpiece, work setting and gripping work can be done quickly and easily, and the height of ball protrusion can be adjusted accordingly according to the workpiece and processing conditions. There is an effect that can be used.
