본 발명은 바이스 장치에 관한 것으로서, 특히 연질 가공부품등을 클램핑할 때나 일정한 가압력이 요구되는 가공물을 클램핑할때 가압력을 조절할 수 있도록하는 가압력조절바이스 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vise device, and more particularly, to a pressure control vise device for adjusting a pressing force when clamping a soft workpiece or the like and when clamping a workpiece requiring a constant pressing force.

일반적으로, 가공물을 클램핑하는 바이스장치는 작업자가 가공부품을 바이스의 조우에 물리고 가압을 할 때 가압력 조절장치가 없으므로 그 가압력을 감각적으로 조정해야 한다.In general, the vise device for clamping the workpiece has no pressure adjustment device when the operator pushes the workpiece into the vise jaws and pressurizes it, so the pressure should be sensibly adjusted.

따라서, 연질가공부품의 경우 물림력이 조금만 과다하여도 가공부품이 변형되고, 양산작업시에 그 가압력을 일일히 감각적으로 조정해야하기 때문에 작업시간의 지연으로 생산성을 저해하는 요인이 되고 있다.Therefore, in the case of soft machined parts, even if the biting force is excessively excessive, the machined parts are deformed, and the pressures must be sensibly adjusted during mass production, thereby delaying the work time, which is a factor that inhibits productivity.

본 발명은 상기한 제반문제점들을 감안하여 발명한 것으로서, 물림에 의한 가공부품의 변형방지 및 연질제품의 양산 작업시 소요되는 시간단축을 도모할 수 있는 가압력조절바이스 장치를 제공함에 그 목적이 있다. 이하 본 발명의 목적을 달성하기 위한 구성을 첨부된 도면에 의하여 기술하면 다음과 같다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a pressure control vise device capable of shortening the time required for preventing deformation of a machined part by mass biting and mass production of a soft product. Hereinafter, a configuration for achieving the object of the present invention will be described with reference to the accompanying drawings.

제 1 도 및 제 2 도에 도시한 바와같이, 바이스본체(1)에 고정설치된 고정조우(2)와 핸들(3)에 그 일측이 고정되어 리이드 스크류(4)의 선단에 설치되는 가압조절밸브(5), 그리고 이 가압조절밸브(5)의 전면부에는 피스톤(6)과 일체로 된 이동조우(7)을 이동조우지지봉(7')로 지지하여 바이스장치(V)를 구성한다.As shown in FIG. 1 and FIG. 2, a pressure regulating valve installed at the tip of the lead screw 4 with one side fixed to the fixing jaw 2 and the handle 3 fixed to the vise body 1. (5) And on the front part of this pressure regulating valve 5, the moving jaw 7 integrated with the piston 6 is supported by the moving jaw support rod 7 ', and the vise apparatus V is comprised.

전기한, 바이스장치(V)의 가압조절밸브(5)는 리이드스크류(4)가 유삽되어 핀(8)에 의해 회동가능케 설치되며 그 상방에 플런저실(9)가 뚫려져 피스톤(6)이 유삽되는 피스톤실(10)과 연통된다.The pressure regulating valve 5 of the vise apparatus V, which has been described above, is installed to be rotatable by the pin 8 with the lead screw 4 inserted therein, and the plunger chamber 9 is opened thereon so that the piston 6 is opened. In communication with the piston chamber 10 is introduced.

플렌저실(9)에는 압력조절노브(11)이 조절가능케 결합되어 내측에 유삽되는 스프링지지구(12)에 밀착되며 그 내측에 유삽되는 플런저(13)은 스프링 지지구(12)에 지지되는 스프링(14)에 의해 탄지된다. 플런저실(9)와 평행하게 뚫려진 오일리턴 피스톤실(15)에는 오일리턴 피스톤(16)이 유삽되어 스프링(17)에 의해 탄지되고, 오일리턴피스톤실(15)는 오일주입통로(18)가 수직연통된다.The pressure control knob 11 is adjustablely coupled to the flanger chamber 9 to be in close contact with the spring support 12 inserted into the inner side, and the plunger 13 inserted into the inner side is supported by the spring support 12. It is touched by 14. An oil return piston 16 is inserted into the oil return piston chamber 15 drilled in parallel with the plunger chamber 9 and supported by a spring 17, and the oil return piston chamber 15 has an oil injection passage 18 therein. Is in vertical communication.

오일주입통로(18)는 플런저실(9)와 연통되어 피스톤실(10)하부에 뚫려진 유로(19)와 수직연통된다. 플런저실(9)와 피스톤실(10)의 연통부(20)은 스프링(21)에 의해 탄지되는 체크볼(22)가 보전되는 유로(23)과 수직 연통되며, 이 유로(23)은 유로(19)와 서로 연통되어져 오일주입통로(18)로 유압유체가 충전되는 구성이다.The oil injection passage 18 communicates with the plunger chamber 9 and vertically communicates with the passage 19 drilled under the piston chamber 10. The communication portion 20 of the plunger chamber 9 and the piston chamber 10 is in vertical communication with the flow path 23 in which the check ball 22 held by the spring 21 is held, and the flow path 23 is a flow path. (19) is in communication with each other is the configuration in which the hydraulic fluid is filled in the oil injection passage (18).

도면 중 미설명 부호 24는 가공물이다.In the figure, reference numeral 24 denotes a workpiece.

이와같이 구성되는 본 발명은 가공물(24)가 가압되기전까지는 이동조우(7)에 가압력이 걸리지 않으므로 스프링(21)에 의해 체크볼(22)가 유로(23)을 차단하고 스프링(14)에 의해 탄지되는 플런저(13)은 플런저실(9)를 차단하게 된다.According to the present invention configured as described above, since the pressing jaw is not applied to the moving jaw 7 until the workpiece 24 is pressurized, the check ball 22 blocks the flow path 23 by the spring 21 and the spring 14. The plunger 13 that is carried out blocks the plunger chamber 9.

이와같은 상태에서 핸들(3)을 돌려 가압조절밸브(5)를 전진시키게 되면 고정조우(2)와 이동조우(7)사이에서 가공물(24)는 가압력을 받게 된다. 그러면, 이동조우(7)과 일체로 된 피스톤(6)이 가압조절밸브(5)에 유삽되어 있으므로, 핸들(3)을 계속 돌리게 되면 이동조우(7)은 후진하는 결과를 초래한다.When the handle 3 is rotated in this state to advance the pressure regulating valve 5, the workpiece 24 is subjected to a pressing force between the fixed jaw 2 and the moving jaw 7. Then, since the piston 6 integrally with the moving jaw 7 is inserted into the pressure regulating valve 5, if the handle 3 is continuously turned, the moving jaw 7 will result in reversing.

이와같이 이동조우(7)이 후진을 하게되면 피스톤실(10)내에 충전된 오일을 압축하게되고, 이오일의 압축은 플런저(13)에 그 압력을 전달하게 된다.As such, when the moving jaw 7 moves backward, the oil filled in the piston chamber 10 is compressed, and the compression of the oil is transmitted to the plunger 13.

이때 압력조절노브(11)에 의해 스프링(14)에 설정된 압력이상으로 플런저(13)에 압력이 작용하게 되면 플런저(13)은 뒤로 밀리게되어 플런저실(9)를 개방하게된다.At this time, when the pressure acts on the plunger 13 by the pressure adjusting knob 11 or more than the pressure set in the spring 14, the plunger 13 is pushed backward to open the plunger chamber 9.

제 3 도의 도시가 이를 나타내는 것으로, 플런저실(9)가 개방되면 피스톤실(10)내에 유압유체는 플런저실(9)로 유입되면서 오일리턴피스톤(16)에 유체압이 작용하게된다.3 illustrates this, when the plunger chamber 9 is opened, the hydraulic fluid flows into the plunger chamber 9 while the hydraulic fluid flows into the plunger chamber 9 so that the fluid pressure acts on the oil return piston 16.

그러면 오일리턴피스톤(16)은 스프링(17)을 압축시키면서 뒤로 밀리고, 유압유체는 오일리턴피스톤실(15)내로 축적되면서 가압조절밸브(5)의 선단부와 이동조우(7)의 후단부가 근접된다.Then, the oil return piston 16 is pushed backward while compressing the spring 17, and the hydraulic fluid accumulates into the oil return piston chamber 15, and the front end of the pressure regulating valve 5 and the rear end of the moving jaw 7 are close to each other. .

이와같이 가압조절밸브(5)와 이동조우(7)이 근접되면 조정,셋팅된 가압력이 가공물(24)을 가압하는 상태로서 핸들(3)의 회동을 멈추면 일정 압력으로 가공물을 클램핑하게 된다.As such, when the pressure regulating valve 5 and the moving jaw 7 are close to each other, the adjusted and set pressing force pressurizes the workpiece 24 and stops the rotation of the handle 3 to clamp the workpiece at a predetermined pressure.

이와같은 상태에서 작업이 완료되면 핸들(3)을 처음방향과 반대방향으로 돌려 가압조절밸브(5)를 후퇴시킨다.When the work is completed in this state, the pressure control valve 5 is retracted by turning the handle 3 in the opposite direction to the initial direction.

그러면, 이동조우(7)과 일체로 된 피스톤(6)이 유삽되어 있는 피스톤실(10)은 공간부가 확보되면서 오일 압축력이 강하됨과 아울러 스프링(14)에 의해 플런저(13)은 플런저실(9)를 차단하게 된다.Then, the piston chamber 10 into which the piston 6 integrated with the moving jaw 7 is inserted is lowered in the oil compression force while the space is secured, and the plunger 13 is moved by the spring 14 to the plunger chamber 9. ) Will be blocked.

그리고, 오일리턴피스톤실(15)에 축적되어 있는 유체는 스프링(17)의 탄성력을 받아 전진이동하는 오일리턴 피스톤(16)에 의해 밀려 오일주입통로(18)내로 이동된다.The fluid accumulated in the oil return piston chamber 15 is pushed by the oil return piston 16 moving forward under the elastic force of the spring 17 to be moved into the oil injection passage 18.

이와같이 이동되는 오일은 오일주입통로(18)과 연통된 유로(19)로 밀려들면서 이와 수직 연결되는 유로(23)으로 들어가 체크볼(22)를 밀어 유로(23)을 개방하게 된다.The oil moved in this way is pushed into the flow path 19 in communication with the oil injection passage 18 and enters the flow path 23 vertically connected thereto, thereby pushing the check ball 22 to open the flow path 23.

유로(23)이 개방되면 피스톤실(10)내로 유체가 유입되면서 가압전의 상태로 환원하게 된다.When the flow path 23 is opened, the fluid flows into the piston chamber 10 and is reduced to the state before pressurization.

이와같은 상태에서 핸들(3)을 계속돌리게되면 이동조우지지봉(7')에 의해 이동조우(7)은 가압조절밸브(5)와 함께 동시에 후진되어 가공물(24)를 교환시킬 수 있는 공간이 확보된다.In such a state, if the handle 3 is continuously turned, the moving jaw 7 is simultaneously retracted together with the pressure regulating valve 5 by the moving jaw support rod 7 'to secure a space for exchanging the workpiece 24. do.

이상과같이 본 발명에 의한 가압력조절 바이스장치는 가공물의 연질 정도에 따라 가압력을 조정, 세팅하므로써, 연질가공부품의 클램핑시 발생하는 가공부품의 변형을 방지할 수 있으며 작업자의 가압력 조절이 필요없이 양산작업시 작업시간의 단축을 도모하여 생산성을 향상시킬 수 있는 발명인 것이다.As described above, the pressing force adjusting vise device according to the present invention can prevent deformation of the processing part generated during clamping of the soft processing part by adjusting and setting the pressing force according to the softness of the workpiece and mass production without the need for adjusting the pressing force of the operator. It is an invention that can improve the productivity by shortening the working time when working.
