Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation panel of a control device for controlling a machine tool, and more particularly to a structure of an operation panel section capable of rotating the direction of the operation panel depending on a state of use.

[0002]

2. Description of the Related Art The body of various machine tools is provided with a control device for controlling the machine tool. Numerical control (hereinafter referred to as NC) NC machine tools such as NC lathes
It has an operation panel for operating the NC machine tool. This operation panel is often fixed to the body of the NC device or the body of the machine tool and does not move.

During setup work such as tool setting, program check and trial cutting, the operator operates the operation panel while confirming the state of the work (workpiece) and tool in the machining area of the machine tool. Confirm and monitor the contents displayed on the CRT display.

[0004]

At this time, if the operation panel is located away from the operator and is not facing the operator, the displayed contents are difficult to see and the operability is poor because it is out of reach. Therefore, a control device of a type capable of accommodating the operation panel has been proposed. For example, Japanese Utility Model Publication No. 53-51390 discloses an operation panel that can be pulled out by a manual operation, but does not describe positioning and holding the operation panel that has been pulled out so as not to move.
That is, when the operator operates or monitors the operation panel,
If the operation panel is easy to move and is unstable, the operation panel may be fixed with one hand and operated with the other hand, resulting in poor operability. In addition, there is a possibility that a monitoring error such as an error or oversight of a display screen such as a CRT or display lamps may occur.

On the other hand, Japanese Utility Model Laid-Open No. 61-205729 and Japanese Utility Model Publication No. 6-37442 disclose a control device in which a movable operation panel can be fixed at an arbitrary position. However, since the bolts and screws are used to fix the operation panel after moving it to an arbitrary position, it takes time and effort to attach and remove the operation panel, resulting in poor workability. Moreover, since the conventional movable operation panel is designed to be moved manually, a large amount of force is required to move the operation panel, and the operability is poor.

The present invention has been made to solve the above problems, and when an operator works in or near the working area of a machine tool, the operator can quickly pull it out of the storage section toward the operator with one-touch operation. It is an object of the present invention to provide an operation panel of a machine tool that can be positioned and held by a machine and can be easily stored.

[0007]

In order to achieve the above-mentioned object, an operation panel for operating a machine tool according to the present invention comprises:
An accommodating portion which is arranged in the vicinity of a working position of an operator who works in the machining area of the machine tool or in the vicinity of the machining area and which is formed in a housing portion of the control device main body or the machine tool main body so that the operation panel can be stored, An operation panel support device that supports the operation panel swingably and can hold the operation panel in the storage unit, and urges the operation panel outward of the storage unit and pulls the operation panel outward by the urging force. And an urging means capable of positioning and holding the operation panel in a predetermined direction.

Between the operation panel 4 and the splash guard 9, a biasing means 19 for biasing the operation panel 4 to the outside of the storage portion is provided, and the biasing means 19 is outwardly actuated by the biasing force. The operation panel 4 that has been pulled out can be positioned and held in a predetermined direction. In this embodiment, a gas-sealed spring member (hereinafter referred to as a gas spring) 19 is used as the urging means. The gas spring 19 is provided with a piston that slides in the axial direction integrally with the piston rod inside a sealed cylinder. The piston divides the inside of the cylinder into two chambers, and nitrogen gas etc. High-pressure gas is enclosed and the pressure of this high-pressure gas is used as a spring. Since the gas spring 19 uses high-pressure gas, it has an advantage that a small spring constant can be obtained with a large initial load and a shock can be relaxed as compared with a metal spring or a rubber spring. Therefore, the operation panel 4, which is weak against impact, can be swung smoothly.

One end 30 of the gas spring 19 is engaged with the splash guard 9 and the other end 31 is engaged with the operation panel 4. That is, the support member 33 that swingably supports the one end 30 of the gas spring 19 is fastened and fixed to the ceiling portion 34 of the splash guard 9 with bolts or the like. The support member 35 that swingably supports the other end 31 of the gas spring 19 is fastened and fixed to the upper surface 36 of the operation panel 4 by bolts or the like.

The gas spring 19 urges the operation panel 4 toward the outside of the storage part so that the operation panel 4 faces the working position P, and the operation panel 4 pulled out by the urging force is
At the end of the stroke, it is temporarily positioned and held in a predetermined direction C (see FIG. 3). Therefore, even if the operator operates the keyboard 6 and the switches 7 of the operation panel 4, the operation panel 4 is not moved and is firmly held by the gas spring 19. The urging means 19 may be a closed cylinder device in which a fluid other than high-pressure gas is hermetically sealed as long as it urges the operation panel 4 to the outside of the accommodating portion, but other types of elasticity such as a compression spring may be used. It may be the body.

In the operation panel support device 18, an upper shaft support portion 37 for rotatably supporting one side end portion 20 of the operation panel 4.
The a and the lower shaft support portion 37b are arranged close to the operation panel front surface 23. The lower shaft support portion 37b is provided on the operation panel 4 side and the shaft support member 21b provided on the splash guard 9 side to rotatably support the shaft member 21a.
And a material for reducing friction provided between the operation panel 4 and the shaft support member 21b (for example, plastic material such as polycarbonate or nylon, oiles material, metal, etc.)
And a bearing member 32 formed by.

Shaft member 2 having a circular cross section (or a cylindrical cross section)
1 a is arranged at a position near one side end 20 of the operation panel 4, and projects downward from the bottom plate 25. The shaft support member 21b, which has a cylindrical cross-section and has an inner diameter portion that is larger than the outer diameter of the shaft member 21a by a predetermined dimension, is provided in the vicinity of one end portion (the left side in FIG. 4) 33a of the bottom surface portion 33 of the storage portion 17 and. It is located on the front side. A stay 51 is fixed to the upper end of the splash guard 9 on one end 20 side by a bolt 51b. A bolt 52, which is an upper shaft member, is fixed to the upper plate 36 of the operation panel 4 below the stay 51.
The outer peripheral portion of the head of the bolt 52 has a support hole 51a for the stay 51.
Has been inserted. The stay 51 and the bolt 52 form an upper shaft support portion 37a.

Since the upper shaft support portion 37a and the lower shaft support portion 37b are arranged close to the front surface 23 of the operation panel 4 and one side end portion 20, when the operation panel 4 is pulled out forward, the operation panel front surface 2
Substantially the entire 3 is exposed from the storage portion 17 to the outside. Therefore, it is possible to prevent the switches 7 and the lamps 8 arranged on the front surface 23 of the operation panel from being obstructed by the storage section 17 and becoming difficult to see, and the operation and monitoring are facilitated.

As shown in FIGS. 3 to 6, the latch mechanism 2
4 is near the other side portion 22 of the operation panel 4 and
Is disposed on the back surface 38 side of the. The latch mechanism 24 has an engaging portion 40 and an engaged portion 41.
By bringing 0 and the engaged portion 41 into contact with each other, the locked state ((A) of FIG. 6) and the unlocked state ((B) of FIG. 6) are repeated, and engagement and disengagement are repeated.
The engaging portion 40 is fixed to the upper plate 36 of the operation panel 4, and the engaged portion 41 is fixed to the ceiling portion 34 of the splash guard 9. Contrary to this, the engaging portion 40 is attached to the ceiling portion 34.
Alternatively, the engaged portions 41 may be fixed to the upper plate 36, respectively.

A lock fitting 43 is attached to the L-shaped member 42 of the engaged portion 41 so as to face the engaging portion 40 side. The case 44 of the engaging portion 40 has a slide member 45 that moves in and out, and an arm 46 that swings with the movement of the slide member 45 to engage and disengage the lock fitting 43.
Are provided. By moving the engaging portion 40 in the direction of the engaged portion 41, the lock fitting 43 pushes the slide member 45. Each time, the arm 46 moves downward and engages with the locking fitting 43 (lock state (FIG. 6A)).
Then, the lock release state (FIG. 6 (B)) in which the arm 46 escapes upward and separates from the lock fitting 43 is repeated.

Therefore, when the operator M gently pushes the front surface 23 of the operation panel 4 rearward with his hand, the engagement portion 40 and the engaged portion 41 repeatedly engage and disengage, and the operation panel 4 moves. It may be held in the storage part 17 or may be pulled out forward. Since it is necessary to fix the operation panel 4 to the splash guard 9 when the NC lathe 1 is conveyed, a fixing piece 47 for fixing the operation panel is attached to the upper plate 36. The fixed piece 47 includes the back surface 38 and the other side portion 2.
The fixing piece 47 is arranged from the corner of 2 toward the rear.
A through-hole 48 is formed in the ceiling 34 for passing a screwable bolt.

Next, a method of using the operation panel 4 will be described. When the operator M performs setup work such as setting of the work 11 and the tool 14, program check, and trial cutting at the work position P, the operation of the NC lathe 1 is performed on the operation panel 4. In order to use the operation panel 4 when the operation panel 4 is stored in the storage section 17, the operation panel front surface 23 located near the other side portion 22 of the operation panel 4 is indicated by an arrow D (FIG. 3). Then, lightly press backward and release.

Then, the slide member 4 of the latch mechanism 24
Since 5 is pushed in by the lock fitting 43 and then protrudes, the arm 46 escapes upward and enters the unlocked state. When the latch mechanism 24 is released from the locked state, the operation panel 4 is operated by the urging force of the gas spring 19 so that the upper shaft member 52 of the upper shaft support portion 37a and the bearing member 3 of the lower shaft support portion 37b.
2, using the shaft member 21a and the shaft support member 21b as a support shaft,
As shown by the arrow B, it automatically rotates in the clockwise direction in FIG. Then, the operation panel 4 is moved to a position in the predetermined direction C corresponding to the stroke end of the gas spring 19 and then temporarily positioned and held there.

Thus, the operation panel 4 can be operated by one-touch operation.
Is pulled out to a predetermined position C where the operator M can easily operate and monitor and stands still. Since the operation panel 4 faces its direction in the vicinity of the operator M who is working at the work position P, the operator M operates the operation panel 4 at the work position P while performing the setup work on the machining area 15. Monitoring can be performed accurately and easily.

Since the operation panel 4 is constantly urged to the outside of the storage portion by the urging force of the gas spring 19, the operation panel 4 can be quickly pulled out to a predetermined outside position by one-touch operation. The operation panel 4 that has been pulled out is positioned and held while being pressed in a predetermined direction C at the end of its stroke. Therefore, even if the operator M extends his hand to operate the keyboard 6 and the switches 7 of the operation panel 4, the operation panel 4 does not move and is still stationary.
You can comfortably operate and monitor.

When the setup work or the like at the work position P is completed, the operation panel 4 is stored in the storage portion 17. In this case,
The front surface 23 of the operation panel is pushed by hand, the operation panel 24 is rotated counterclockwise in FIG. 3, and the engaging portion 40 of the latch mechanism 24 is pressed against the engaged portion 41. Then, the protruding slide member 45 is pushed by the locking metal fitting 43 and the arm 46 moves downward, so that the arm 46 engages with the locking metal fitting 43 and enters a locked state. In this way, when the latch mechanism 42 is in the locked state and the hand is released, the operation panel 4
Are held in the storage unit 17. In this way, the storage unit 17
Since the operation panel 4 is stored inside, the splash guard 9
Since it does not protrude from the machine body, the operation panel 4 does not obstruct the passage of traffic.

As described above, according to the present invention, the operator M sets the work 1 on the machining area 15 of the NC lathe 1.
While carrying out setup work such as removal and installation of 1 and tool 14 and inspection work of the cutting processing state, extend the hand to operate the keyboard 6 and switches 7 of the operation panel 4, the screen and lamp of the CRT display unit 5. Class 8 can be monitored. At this time, the operation panel 4 that has been pulled out faces the operator, is located in the vicinity thereof, and is stable without movement. Therefore, the operability is improved, the operation error does not occur, the CRT display section 5 and the lamps 8 are easily monitored, and the monitoring error such as the misreading or the oversight can be prevented. Note that instead of positioning and holding the operation panel 4 at the stroke end of the gas spring 19, the operation panel 4 pulled out by the urging force comes into contact with the operation panel 4 in a predetermined direction C to position the operation panel 4. Means may be provided.

Further, in the present invention, the operator operates the operation panel 4
With the one-touch operation of lightly pushing the front surface 23 of the operator, the operation panel 4 can be quickly pulled out and positioned and held when using the operation panel through the gas spring 19 and the latch mechanism 24. After the operation panel is used, the one-touch operation is performed. Thus, the operation panel 4 can be easily stored in the storage section 17. Therefore, it does not take time and effort to position and fix the operation panel 4, and a large force is not required to move the operation panel 4.

Compared with the prior art in which the operation panel is installed separately from the machine tool, in the present invention, other than during setup work or inspection work in the machining area 15, for example, when monitoring the operating state of the NC lathe 1, When the operator moves, the operation panel 4 in the stored state does not get in the way, and the operator panel is not accidentally touched, so that the safety is improved. In the above-described embodiment, the operation panel is rotatably attached to the splash guard (machine tool body side member), but the control device is placed separately so that the operation panel can be rotated on the control device body. May be attached. For example, in the case of a horizontal machining center or the like, an operation panel may be rotatably provided on the front side of the main body of the control device attached to the side surface of the splash guard. The same reference numerals in the drawings indicate the same or corresponding parts.

[0034]

Since the present invention is configured as described above, when the operator is working in the machining area of the machine tool or in the vicinity of the machining area, the operator can quickly pull out the operation panel from the storage portion to the operator by one-touch operation. It can be positioned and held, and the operation panel can be easily stored.
