This reaction cylinder (150) functions to cause the lifting means (160) to generate a reaction force at a pressure predetermined by the first regulator (410) described below.

Furthermore, a first guide path (113) is formed on the other side of one side of the main body plate (110). The first guide path (113) plays a role in guiding the raising and lowering movement of the lifting portion (200) described below.

In addition, further included between the motor base block (111) and the reaction cylinder block (140): a stopper (120) that controls the movement of the lifting means (160), and a stopper block (130) that supports the stopper. ). In the absence of such a stopper (120), the ball screw (220) will descend uncontrollably due to the lifting means (160). Therefore, in order to control the unrestricted downward movement of the ball screw (220), the stopper (120) is used.

Next, the lifting part (200) moves up and down through the first guide path (113) of the supporting part (100).

This kind of lifting part (200) is connected with the lifting means (160) through the through hole of the motor base block (111) of the supporting part (100) on one side for lifting.

Here, the push cylinder (260) plays a role in controlling the load of the rebound force generated from the holder (310) described below through the second adjuster (420).

In addition, the lifting part (200) includes a ball screw mounting block (210), a ball screw (220), a cylinder upper mounting block (230), a cylinder lower mounting block (240), a coupling (250), and a push cylinder (250). 260).

One side of the ball screw mounting block (210) is curved, and a second guide path (211) is formed on the inner surface of the other side that is curvedly extended from the one side.

The ball screw (220) is connected to the outside of one side of the ball screw mounting block (210).

The coupling (250) is combined with the ball screw (220) on one side and the lifting means (160) on the other side. The push cylinder (260) is combined with the inside of one side of the ball screw mounting block (210).

On the other hand, the cylinder upper mounting block (230) includes a first guide member (231) that raises and lowers the second guide path (211) of the ball screw mounting block (210).

Furthermore, the cylinder lower mounting block (240) is included in a second guide member (241) that raises and lowers the first guide path (113) on one side and is connected to the ball screw mounting block (210) on the other side.

Finally, the lifting part (200) further includes a cylinder propeller (180). The lower part of the cylinder propeller (180) is combined with the other side of the upper cylinder mounting block (230), and the side surface is connected with the control push cylinder (260). The action push cylinder stop part (181) is combined.

Using a graph representing the torque-rotation speed characteristics in this manner, the multifunctional scoring head (1000) of one embodiment of the present invention can be selectively utilized as a servo head, a low pressure head, or an air head, etc.

That is, if the servo head is used, if a strong pressure is used to make the push cylinder (260) move forward, the reaction force transmitted through the wheel (not shown) will not be transmitted through the push cylinder (260). The offset is directly transmitted to the lifting means (160), so that it can be used in the same way as the existing servo head. At this time, the reaction cylinder (150) is in the off state (standby state).

Secondly, after studying the use of low-pressure heads, the usual lifting means (160), such as servo motors, cannot be used in a reproducible manner in the low-pressure range, that is, the lower torque (Torque) range (because in general motors The lower torque range has the characteristics of non-linear motor torque, so it cannot be controlled). At this time, if the regulator part (400) is used to cause the reaction force of a certain pressure to pass through the reaction cylinder (150), so that the lifting means (160) operates with the reaction force, the lifting means (160) must generate a load equivalent to the cutter. + The torque of the reaction force load of the reaction cylinder (150). Thereby, when the reaction force of the reaction cylinder (150) is increased to the stable range of the lifting means torque, the lifting means (160) can operate stably, and the wheel pressure can be controlled consistently. That is, a low-pressure head for thin plate cutting can be used. At this time, the push cylinder (260) must be in the On state and set to the maximum pressure.

In addition, if the air head is used, if the position of the lifting means (160) is controlled instead of torque control, the pressure of the push cylinder (260) is controlled in the second regulator (420), It can be used in the same way as the existing air head. At this time, the reaction cylinder (150) is in the disconnected state (standby state).

This will be further studied with reference to Figures 4 to 7 .

If explained in more detail, the reaction cylinder (150) performs pressure control using the first regulator (410) to generate a reaction force on the lifting means (160) until the torque of the lifting means (160) can reach the torque. Operate within the stable range.

In addition, the push cylinder (260) uses the maximum pressure using the second regulator (420) to transmit the torque resulting from the combination of the lifting means (160) and the reaction cylinder (150) to the wheel.
