Abstract

PURPOSE:To shift manually the optional speed and the shifting quantity by providing a manual shifting speed data input means and a shifting quantity data input means and inputting directly the optional manual shifting speed and manual shifting quantity from an external part to the control part. CONSTITUTION:From the external part to a control part 1, a shifting direction data input is given by a shifting direction data input means 11, a necessary optional shifting quantity data input is given by a shifting quantity data input means 13 and a necessary optional manual speed data input is given by a manual shifting speed data input means 13. Next, when the manual starting input signal is given by a manual starting input means 14, the shifting direction data input, the shifting quantity data input and the manual shifting speed data input is fetched into the control part 1, by the action of an arithmetic part 3 by the control program stored in a memory part 2, the shifting command is given from the control part 1 to a driving control part 4, and the driving control part controls a motor 5 to be controlled. Thus, the optional action can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a numerical control device, and relates to an improvement in manual operation thereof.

[Conventional technology]

Figure 2 is a block diagram showing a conventional numerical control device.
In the figure, 1 is a control unit including a central processing unit, 2 is a storage unit that stores control programs and data, 3 is a calculation unit that executes all numerical calculations, 4 is a drive control unit that drives the controlled motor 5t, and 11 is a storage unit that stores control programs and data. Movement direction data input means for inputting movement direction data for designating the movement direction; 14 a manual start input means for receiving a manual start input signal means; 15 a manual start input means for inputting movement direction data for specifying the movement direction; 16 is a sizing movement code data input means for providing data input for specifying fixed-dimension movement; This is a manual speed code data input means.

Next, the operation will be explained. Movement direction data input means 1
After inputting movement direction data from 1, fixed size movement code data input from the fixed size movement code data input means 15, and manual speed code data input from the manual speed code data input means 1, the controller 1 is given input.

A manual start input signal is given to the control section 1 from the manual start input signal means 14 . Next, in the control unit 1, the fixed size movement amount specified by the fixed size movement code data input from among the fixed size movement amounts stored in the storage unit 2.

Based on the manual movement speed specified by the manual speed code data input from among the manual movement speeds stored in the storage unit 2 and the direction specified by the movement direction data input, the drive control unit is operated by the operation of the calculation unit 3. Give a movement command to 4. Next, the drive control unit 4 moves the controlled motor 5 in the commanded direction by the designated movement amount at the commanded speed.

[Problem that the invention seeks to solve]

Conventional numerical control devices are configured as described above, so when operating a controlled motor by manual operation, a fixed amount of movement and a certain movement speed are selected from among the amount of movement and movement speed already stored in the numerical control device. Movement speed can only carry money,
There was a problem in that the controlled motor could not be operated at any speed and any amount of movement.

This invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a numerical control device that can be manually moved at any speed and by any amount of movement.

[Failure to solve the problem]

In the numerical control device according to the present invention, the control section is provided with a manual movement speed data input means and a movement amount data input means as external H3 human power means, and an arbitrary manual movement speed and an arbitrary manual movement amount are input from the outside to the control section. It is designed to be input directly.

[Effect]

The manual movement speed data input means in this invention directly inputs an arbitrary movement speed for driving the controlled motor to the control unit from the outside as data, and the movement amount data input means inputs arbitrary movement data as data. input directly to the control unit from the outside. By inputting these two types of data and movement direction to the control unit from the outside, and first inputting a manual start signal to the control unit, the controlled motor can be moved in any direction, at any speed, and by any amount. can do.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a control unit including a central processing unit, 2 is a storage unit, 3 is a calculation unit, 4 is a drive control unit, 5 is a driven motor, 11 is a movement direction data input means, and 12 is movement amount data. Input means, 13, manual movement speed data input means, 14
is a manual activation input means.

Next, the operation will be explained. The control unit 1 is externally inputted with the movement direction data input means 11 to input movement direction data, and the movement amount data input means 12 to input any necessary movement amount data into the manual movement speed data input means 13. When a manual speed data input is given and then a manual start input signal is given by the manual start input means 14, the movement direction data input, movement amount data input and manual movement speed data input are taken into the control section 1 and stored in the storage section. According to the control program stored in 2, a movement command is given from the control unit 1 to the drive control unit 4 by the action of the calculation unit 3, and the drive control unit 4 controls the controlled motor 5 to achieve the target. Any behavior can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, since the control unit is provided with the movement amount data input means and the manual movement speed data input means as external input means, it is possible to arbitrarily set the movement amount and the moving speed money from the outside. Therefore, the direction, amount of movement, and speed that meet the required conditions can be realized by fully manual operation, for example,
When machining is interrupted, complex evacuation operations are possible.
