Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device for displaying the moving direction and position of a tool rest in a numerically controlled machine tool, such as a lathe.

A particular feature of this display device is that it automatically indicates the moving direction and numerically displays the moving position of the tool post in response to the operation of the operating lever that changes the moving direction of the tool post.

Conventionally, the configuration of this type of display device is schematically shown in FIG. 1 using a lathe as an example. To explain this FIG. It has an operating lever 3 for switching control between the front and back direction (X direction) and the parallel direction (two directions) with respect to the workpiece.

This operating lever 3 switches the direction of movement of the tool post by selecting one of the movement directions (X direction and two directions) specified in relation to the lever and moving the lever 3 to the specified position. It is.

Reference numeral 4 denotes a control device for the lathe 1, and this control device 4 includes a position display section 5 that indicates the turret movement position using numerical information, and a display of the movement direction (X direction and two directions) on the position display section 5.
It was equipped with a display changeover switch 6 for selecting.

FIG. 2 is an enlarged view of the position display section 5 and display changeover switch 6 of the control device 4.

In such a conventional configuration, when the user wants to move the operating lever 3 on the operating unit 2 of the lathe 1 in the desired direction of movement, for example, in the X direction, the switching operation is performed by moving the operating lever 3 on the operating unit 2 of the lathe 1 to the X direction indicating side. At the same time, the position display section 5 on the control device 4 side is instructed to display in the X direction by using the display changeover switch 6, whereby the position display section 5 displays the position of the turret in the X direction. .

In this case, since the lathe 1 and the control device 4 are installed at a distance, it is necessary to go back and forth between the operation section 2 of the lathe 1 and the display changeover switch 6 of the control device 4 when switching the movement of the tool post. This switching operation was extremely troublesome.

The present invention was proposed in order to solve the above-mentioned drawbacks, and in response to an operation to change the moving direction of the operating lever 3 in the operating section 2 of the lathe 1 shown in FIG. The control device 4 detects the moving direction of the tool post.
Instructions are given on the side display and the movement position of the tool post in response to these instructions is displayed numerically, eliminating the need for the troublesome work of going back and forth between the lathe and the control device as in the past. It is something.

FIG. 3 is a circuit diagram showing the configuration of the present invention, and FIG. 3 will be explained below.

Block A represents the operating section 2 of the lathe 1 in FIG. 1, and has an operating lever 3 for switching the movement of the tool post.

This operating lever 3 is connected to one of the contacts 7a to 7e of the contact group 7 and selectively switches between these contacts 7a to 7e.

The contact 7a is on the (-) side in the X direction, the contact 7b is on the (+) side in the X direction, the contact 7c is in the neutral position, and the contact 7d is in the Z direction.
The contact point 7e is defined as the (-) side in the Z direction and the (+) side in the Z direction.

Block B is this control section and is provided, for example, on the control device 4 side in FIG. 1.

In this block B, signals from contacts 7a and 7b are introduced into the input side of OR gate G1, and signals from contacts 7d and 7e are introduced into the input side of OR gate G2.

The gate output of the OR gate G1 serves as a set input for the J-type flip-flop F/F, and the gate output of the OR gate G2 serves as a reset input for the flip-flop F/F.

The set output of the flip-flop F/F is block C.
The reset output of the flip-flop F/F is led out to the display section indicated by block C and one input terminal of AND gate G4.

Then, the output of an The output of the Z register 9 containing position information is introduced.

The gate outputs of the AND gates G3 and G4 are sent to the display circuit of the display section via the OR gate G5.

The display section of the block C described above uses a display circuit to display the position information from the X register 8 or 2 register 9, to numerically indicate the position of the turret, and also to indicate the X direction by the set output of the flip-flop F/F. A lamp indicating that it is a two-way instruction is lit, and a lamp indicating that it is a two-way instruction is lit by the reset output.

Further, this display section is equipped with a display changeover switch 10 so that the display in the X direction and the two directions can be manually switched as necessary. are introduced on the input side of each.

FIG. 4 shows the appearance of the display section indicated by block C.
It is equipped with a display window 11 that indicates the position of the turret, lamps 12 (X direction) and 13 (two directions) that indicate the direction of movement of the turret, and a bush type display changeover switch 10.

To explain the operation shown in Fig. 3 a little more, when the operator wants to move the tool post in the (+) direction of
is switched from the neutral position (contact 7c) to contact 7b.

Then, the selection signal of the operating lever 3 is introduced to the set side of the flip-flop F/F via the OR gate G1, and the flip-flop F/F is set.

This means that the flip-flop F/F has detected that the X direction has been selected by the operating lever 3, and the set output of the flip-flop F/F lights up the lamp 12 on the display that indicates the direction of movement of the tool post. At the same time, the AND gate G3 is enabled and the position information of the X register 8 is sent to the display circuit of the display section, and the position of the tool rest is displayed on the display window 11.

In this case, the contacts in the contact group 7 are defined as (+) and (-) sides in the X direction and two directions, and although not particularly shown in the figure, the (+) and (-) sides are detected. The position information of registers X and z is controlled in response to the detection means.

On the other hand, if you want to move the turret in the (-) direction of 2,
The operating lever 3 is switched and connected to the contact 7d.

Then, the selection signal of the operating lever 3 is introduced to the reset side of the flip-flop F/F via the OR gate G2,
The flip-flop F/F is reset.

This means that the flip-flop F/F is
It means that the direction selection is detected, and the flip-flop F
The reset output of /F turns on the lamp 13 that indicates the direction of movement of the tool rest in the display section, makes AND gate G4 valid, sends the position information of the second register 8 to the display circuit of the display section, and displays the direction of the tool rest in the display window 11. The location will be displayed.

Furthermore, the display changeover switch 10 is used when it is desired to change the display manually, and when the changeover switch 10 is pressed, this switch signal is sent to the OR gate G1. Introduced in G2.

For example, when the flip-flop F/F is in the set state (X direction detection) and the switch signal is introduced, the flip-flop F/F becomes the reset state, or when the flip-flop F/F is in the reset state and the switch signal is introduced. When introduced, the flip-flops F/F enter a set state, and each display can be switched to a display state in a direction different from the previous state.

As described above, the tool post position display device of the present invention detects the moving direction of the tool post according to the contact point selected by the operation of the operating lever that switches and controls the moving direction of the tool post, and responds to this detection. It is configured to instruct the position display according to the direction of movement and display the position of the turret numerically, and the direction of movement and position of the turret are automatically displayed in response to the operation of the control lever. This eliminates the need for the operator to move between the lathe and the control device, which was previously the case, and the switching operation becomes extremely simple, which is extremely effective in improving work efficiency. Become.
