Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a structure of an NC control device for controlling a numerically controlled (hereinafter referred to as NC) machine tool and an operation panel portion for the NC control device.

[Conventional technology]

In the NC controller fixedly installed on the side surface of the NC machine tool such as a machining center, the operation panel is also fixed to the NC controller. On this operation panel, a CRT display section that displays the NC machining program, each tool offset amount, coordinate system numerical value, etc., a keyboard for changing the CRT display screen, changing the display contents, NC machine tools, etc. There are switches such as a push button switch for manual operation, a switching switch for manually turning the cutting agent on and off, and lamps for indicating the selection state of each switch. Worker CR
While observing the T screen and lamp display, various switches are operated to operate the NC machine tool in manual and automatic modes.

[Problems of conventional technology]

However, the operation panel of the NC controller fixedly installed on the side surface of the conventional NC machine tool is fixed to the NC controller casing. That is, it was designed at a height position corresponding to the average height that fits the operator. However, each operator's height is different, and people who are several tens of centimeters higher or lower than the average height see the CRT display screen from above or below, so it is difficult to see the display contents and the name plate is used to explain the operation switch. There was a problem that the name written on was difficult to see and it was difficult to operate the machine. Especially when performing a tape check of the machining program,
As each switch is operated while looking at the CRT display screen for a long time, the operator who is significantly different from the average height will continue to have an unnatural posture, increasing fatigue and increasing This is one of the causes of misrecognition and glitches on the display screen, which may cause a collision of the machine moving part due to an erroneous operation, which is also a safety problem.

On the other hand, a method of moving the entire operation panel is also known as seen in a pendant type, but it requires a floor space, cannot be fixed immovably at any position, and the structure itself becomes large and costly. There was a problem such as becoming high.

The purpose of the present invention is to solve the problems of the operation panel of the conventional NC control device, reduce the fatigue caused by the unnatural posture of the operator, and improve the safety of the NC control device pursuing ergonomics. It is to provide an operation panel.

[Means for solving problems]

 In order to achieve the above object, the following means are taken.

A first means is a numerical control device fixedly installed on a side surface of a machine body for controlling a numerically controlled machine tool,
A base body that forms the main body of the control device, an operation panel that is movable in the up and down direction relative to the base body, and one end is fixed to the operation panel, and when the operation panel is moved, the operation panel is maintained in an arbitrary predetermined position in a floating state. It is a control panel of a shiftable numerical control device including a balance maintaining body.

The second means is provided with respect to the first means in a base body which constitutes a control device or an operation panel which is movable in the vertical direction relative to the base body. It is a control panel of a shiftable numerical control device with a fixing member added to fix it at a predetermined position.

[Action]

Loosen the fixing member of the operation panel fixed to the NC control device,
The control panel is adjusted by lifting or pushing it down to a position where an operator can easily operate it, and the control panel is fixed to the NC control device by a fixing member.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, an NC controller C is fixed to a side surface of a machine tool M such as a machining center. The NC control unit C is provided with a control panel 1. The operator of the machine tool M mounts on the step A, and the workpiece T (not shown) fixed on the tool T mounted on the spindle S and the table or pallet.
The machine tool M is operated in the manual mode and the automatic mode while monitoring the state of the CRT display screen on the operation panel 1 while operating the keyboard and various switches.

2 and 3 show the operation panel 1 provided in the NC control device C.
The front view and sectional drawing of are shown. The base plate 3 of the operation panel 1 is attached to the casing 2 of the NC control device C, and the CR for displaying various data such as machining programs on the base plate 3
A name plate 9 to which the T display section 4 and the keyboard 6 are attached and a name plate 10 to which various switches are attached are fixed. The CRT body 4a is fixed to a support 8 fixed to the base plate 3, and a dustproof glass cover is fitted on the base plate 3 on the front surface of the CRT body.

A gas seal is provided between the mounting portion 8a fixed to the support 8 and the mounting portion 2a fixed to the housing 2 to balance the weight of the operation panel 1 when the operation panel 1 is slid vertically. A mold cylinder 5 is provided. Gas sealed cylinder 5
Is divided into 5a and 5b cylinder chambers by a cylinder 12 and a piston 11, and the cylinder chambers 5a and 5b are piston 11
It communicates with a small hole cut in. Also, cylinder chamber 5
The a and 5b are filled with compressed gas, and the cylinder chambers 5a and 5b
The piston is calculated from the load obtained by multiplying the difference in cross-sectional area of
The load value obtained by subtracting the sliding resistance of 11 parts and the weight value of the control panel 1 are almost balanced. Therefore, the operation panel 1 does not drop even if the fixing member (described later) is loosened. Further, in order to slide the operation panel 1 in the vertical direction, the sliding resistance of the slide member, which will be described later, is improved, and the operation panel 1 can be moved up and down with a small load. Further, the method for weight-balancing the operation panel is not limited to the gas-sealed cylinder described above. A closed cylinder other than gas may be used,
Further, a balance weight may be attached at a position facing the operation panel via a fulcrum provided on the fixed side.

2 and 4 show a slide member 13 on which the operation panel 1 slides on the housing 2. The slide member 13 is shown in FIG.
As shown in 13b, 13c, and 13d, the housing 2 is provided at four places.
A plate 2b that reinforces the case 2 is fixed to the case 2, and the case 2 and the plate 16 are bolted with the slide plate 15 in between.
It is screwed by 14. The slide plate 15 is preferably made of a plastic resin having good slidability, such as an olefin resin. On the side of the slide plate 15,
A groove 15a into which the base plate 3 of the operation plate 1 is inserted is cut, and the base plate 3 is guided by the groove 15a and slides in the vertical direction.

A fixing member for fixing the operation panel 1 to the housing 2 in FIGS. 2 and 5.
Shows 17. A plate 2c for reinforcement is fixed to the housing 2, and an elongated hole 2d into which a screw 18a is inserted is provided. Grip knob 1
The screw 18a is fixed to the screw 8, and the nut is attached to the screw 18a through the base plate 3 of the operation panel 1 and the housing 2 through the rotation washer 19.
20 are screwed together. When the grip knob 18 is rotated in the clockwise direction, the nut 20 is stopped by the washer 19 for preventing rotation, so the screw 18a moves in the screw axis direction, and the base plate 3 moves through the pipe portion 3a fixed to the base plate 3 portion. It is sandwiched and fixed to the housing 2 by the grip knob 18 and the nut 20. Reference numeral 21 is a dustproof felt, which is adhered to the surface of the housing 2 where there is no slide member 15.

Next, a method of using the present invention will be described.

The grip knob 18 is rotated counterclockwise so that the operation panel 1 can be vertically moved with respect to the housing 2. Since the operation panel 1 is weight-balanced by the gas-sealed cylinder 5,
It does not fall. The operation panel 1 is slid up and down to a height position where the operator can easily use it. Even at this time, since the weight is balanced, it can slide in the vertical direction with a small load. When the height position is determined, the grip knob 18 is rotated clockwise to fix the operation panel 1 to the housing 2.

[Effect of device]

As is clear from the above description, according to the present invention, NC
The operator of the machine tool can easily move and fix the operation panel (CRT display, various switches, lamps, etc.) to a position where it is easy for the operator to operate. The feeling was reduced, and fatigue was not accumulated, improving safety.

Moreover, since a gas-sealed cylinder or the like is used for the weight balance of the operation panel portion that slides in the vertical direction, the weight balance can be achieved with a compact structure. Therefore, it is possible to slide the operation panel with a small force despite the vertical slide.
