Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual handle data input device for directly inputting various data to an NC device by operating a manual handle.

[0002]

2. Description of the Related Art Since the conventional manual input device adopts a system in which it is connected to the main operation panel with a cord, the operation is performed while looking at the manual input device and the display section of the main operation panel. However, there is a problem in that the operation procedure and operability are complicated and erroneous operation cannot be avoided.

Therefore, as disclosed in Japanese Unexamined Patent Publication No. 4-261750, an input key for inputting a work coordinate system and the like is provided in a portable manual input device connected to a main operation panel by a cord, and the coordinates of each axis are coordinated. It has been proposed that displays are arranged to display values in real time. However, since the box body must be held and operated by hand, the operability is complicated and the problem remains that erroneous operation cannot be avoided.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention is to provide a novel data input device for a manual handle, which aims to solve the problems.

[0005]

According to the present invention, an axis is selected and displayed near each axis manual pulse handle of an NC machine tool.
The manual handle data input device is characterized in that it is provided with one indicator and further with one operating member for setting and resetting the manual pulse handle for each axis near the indicator.

[0006]

According to the present invention, since one indicator is provided near the manual pulse handle for each axis of the NC machine tool, the manual pulse handle for each axis can be operated while looking at the indicator in this near chamber and is simple. As a result, unnecessary attention is eliminated and operation mistakes are eliminated, and it is possible to operate the manual pulse handle of each axis with good work efficiency. Also, after specifying the angle, arc, point, etc. with one operating member, set the manual handle pulse handle operation to a predetermined value while observing the display, then set the condition by the operating member set operation and manually feed. Since the manual cutting is performed on two axes simultaneously by rotating the pulse handle, the manual roughing operation can be executed without looking at the operation panel once the manual cutting feed is set.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments shown in the drawings will be described below. Figure 1
Is a perspective view of the manual handle data input device of the present invention, and FIG. 2 is an enlarged plan view of a display portion of the manual handle data input device of the present invention. FIG. 3 is a flow chart showing the operating procedure of the present invention. FIG. 4 is a block diagram of the data input device, and FIG. 5 is an explanatory diagram showing an angle program example.

In FIG. 1, the front portion 4 of the knee 2 on which the table 3 of the NC machine tool 1 is placed is provided with manual pulse handles 5, 6, 7 for each axis. One indicator D for selectively displaying the axis designated by the axis selection switch S is provided on the upper edge of the front surface portion 4 near the manual pulse handles 5, 6, 7 for each axis. One operation member P including a set button B1 and a reset button B2 is provided near the manual pulse handle, that is, on the right edge of the display D.
The display D has an axis display selected as shown in FIG.
The angle (A), the arc (R), and the point (P) are switched and displayed.

Next, the configuration of the data input device of the present invention will be described with reference to FIG. The data input of the angle (A) of each axis is connected so as to be input to the switching control unit C1, and the axis selection button S of the operation member P switches the axes. And set button B
Each time 1 is pressed, the angle (A), the circular arc (R), and the point (P) are controlled so that numerical values can be input, and the reset button B
Press 2 to reset all. Under the control of the switching control section C1, when the manual pulse handles 5, 6 and 7 for each axis are operated, the pulse generated for each movement unit is put into the storage control section C2 as set information (data pulse) and the central processing computer 10 is operated. The central processing computer 10 (CPU) switches and displays the data display at the angle (A), the data display at the arc (R), and the data display at the point (P) on the display D. Further, the central processing computer 10 (CPU) distinguishes the set information (data pulse) into an angle (A) on the XY plane, an arc (R), and a point (P), and transmits it to the NC control unit 11. Based on the setting conditions “angle (A), arc (R), point (P)”, the tool (not shown) of the machine tool 12 is simultaneously operated based on the operation of the manual pulse handles 5, 6, 7 for each axis. 2-axis manual cutting. It has a relationship structure.

Next, the operating procedure will be described with reference to FIG. Select the manual feed axis (b) and select the manual feed axis (b) and the automatic feed axis (c) to operate each operation member P.
Press the set button B1 for X, PY, PZ to select the angle (A)
Alternatively, either the arc (R) or the point (P) is selected.
Thereafter, the set information (data pulse) is transmitted to the central processing computer 10 (CPU) based on the operation of the manual pulse handles 5, 6 and 7 for each axis, and the display DX, DY,
DZ displays. Here, as shown in FIG. 5, the input operation such that the straight line connecting the position P1 and the position P2 is the angle A from the X-axis direction is performed by checking the display of the position P1 with each axis manual pulse handle 5,6. While matching. Here, the set button B1 is pressed and stored, and then the position P2 is adjusted while watching the display, and the set button B1 is pressed and stored.
By the above operation, the stored set information (data pulse)
Are stored in the NC control unit 11 as position information.

With the above operation, all the data input operations are completed, and then the machine tool 12 is put into an operating state. In this state, when the X-axis manual pulse handle 5 is turned, the movement amount (pulse number) in the Y-axis direction is automatically determined in proportion to this rotation amount, that is, the movement amount (pulse number), and simultaneous two-axis manual cutting is performed. Do.

The feature of this method is that once the manual cutting feed is set, the manual roughing operation can be repeatedly executed without looking at the operation panel.

It is needless to say that the present invention is not limited to each of the above-described embodiments, and design changes can be further made within the scope of the invention.
For example, the position of the indicator provided in the vicinity of the manual pulse handle can be freely changed. [0014]

[Effect] According to the present invention, since one indicator is provided in the vicinity of each axis manual pulse handle of the NC machine tool, each axis manual pulse handle can be operated while looking at the indicator in this chamber. It is simple, eliminates unnecessary attention, eliminates operational mistakes, and allows you to operate manual pulse handles for each axis with good work efficiency. Also, after specifying the angle, arc, point, etc. with one operating member, set the manual handle pulse handle operation to a predetermined value while observing the display, then set the condition by the operating member set operation and manually feed. Since the manual operation with two axes is simultaneously performed by the rotation operation of the pulse handle, once the manual cutting feed is set, there is an effect that the manual roughing operation can be executed without looking at the operation panel.
