Description

[Detailed Description of the Invention] [Field of Application of the Invention] This invention relates to an inspection device for an NC device that can be used for final inspection of the NC device, inspection at the time of shipment, and various other inspections.

[Description of Prior Art] As an example of a conventional NC device inspection device, there is an example using an inspection personal computer equipped with a diagnostic program necessary for inspecting an NC device.

However, in such conventional inspection equipment for NC equipment, it is necessary to actually directly operate the operation panel attached to the NC equipment (hereinafter referred to as the NC panel), or to check the internal wiring between the personal computer and the NC panel. I had to find a way to connect it to the NC panel and operate the NC panel.

However, in the former example of direct operation, the inspector has to operate both the NC panel and the personal computer, which is cumbersome. Further, in recent years, personal computers are often installed in central control rooms, so in such cases, it is not only a nuisance, but also difficult to inspect.

On the other hand, in the latter example of wiring connection, the wiring work itself is troublesome, and the NC panel itself must be inspected separately during product inspection.

[Purpose of the invention] In view of the above, the object of this invention is to provide an inspection device for an NC device that can easily and reliably inspect an NC device.

[Summary of the invention] In order to achieve the above purpose, this invention
As shown in the outline in the figure, there is an operating device driving device 5 that drives the operating device 3 of the NC device 1, and a drive command signal Si is output to the driving device 5, and the output signal So of the NC device 1 is appropriately controlled. An inspection unit 9 that inputs signals via the intermediate device 7 and inspects the signal output state of the NC device 1 constitutes an inspection device 11 for the NC device. The controller 3 of the NC device 1 can be operated via the controller 5.

[Example of idea] Examples of this invention will be described below.

As shown in Fig. 2, the inspection device 11a of the NC device
is the inspection personal computer 9a and the intermediate box 11.
and an operating device drive device 5a.

The inspection personal computer 9a has a CPU that has a diagnostic function for the NC device and various calculation functions, a keyboard 13,
It has a CRT 15 and a communication section 17. The communication section 17 can perform both parallel communication and serial communication, and the parallel communication section is connected to the parallel communication line _L1 , and the serial communication section is connected to the serial communication line _L2 .
However, the inspection computer 9a and the intermediate box 1
If the distance to 1 is long, the parallel communication line
It is also possible to change L ₁ and L ₂ to serial communication lines.

The intermediate box 11 processes the control unit 5b of the operating device driving device 5a, one aspect of the intermediate device, that is, the servo motor M, the encoder E attached to the servo motor, and the output signal of the encoder E. The position calculation unit 19 is configured to include a position calculation unit 19. Note that these intermediate devices mentioned in this example are provided to inspect the servo motor system of the NC device 1 in correspondence with the actual machine.

Details of the operating device drive device 5a are shown in FIG. 3.

The operating device drive device 5a is detachably attached to the front side of the NC panel 21, and has a large number of operating actuators 23 for operating a large number of operating devices such as key switches, push buttons, changeover switches, etc. therein. .

In FIG. 3, the actuator 23 is composed of a solenoid device 23d equipped with a return spring 23a at the rear end to reciprocate the tip action point 23c of the rod 23b, and a drive voltage Sa based on the signal Si shown in FIG. The tip 23c acts to press the operating device 3. As the operation actuator 23, it is also possible to use an actuator that rotates a switch in multiple stages.

Next, the operation of the inspection device 5a of the NC device having the above configuration will be explained.

First, as shown in FIG. 3, the inspector attaches the operating device drive device 5a to the NC panel 21.

Next, the keyboard 13 of the inspection computer 9a is operated to output a signal Si for operating a specific operation device 3 to the control unit 5b of the operation device driving device in the intermediate box 11.
b outputs the actuator drive signal Sa;
A predetermined actuator 23 of the operating device driving device 5a shown in FIG.
The rod tip 23c presses the designated operating device 3.

The inspector performs these operations using the NC device 1.
This allows you to perform operations as if you were directly operating the NC panel.

Therefore, for example, if the above operation is performed on the operating device 3 which drives a specified servo motor, since the actual servo motor is not yet attached to the NC unit 1 at the time of shipment, only a motor drive voltage, for example, is generated in the output section.

In this embodiment, this voltage is used to drive the actual servo motor M provided in the intermediate box. Then, the actual rotational state of the motor M is actually measured by the encoder E, and the current position to be driven by the motor M later is calculated and returned to the detection personal computer 9a.

As described above, the inspector can operate the NC device 1 while being in front of the inspection personal computer, and can easily observe the results using the CRT 15 or the like. Furthermore, at this time, since the operating device 3 on the NC panel 21 is actually being operated, the panel itself is also being inspected.

In the above example, the servo motor M is driven by operating the NC panel 21, but the NC panel 21 is operated to drive the servo motor M.
Of course, various tests can be performed by directly connecting the output section of the device 1 and the communication section of the testing personal computer.

In addition, as a drive command method for the operating device 3 on the PC 9a side, in addition to using the keyboard 13 of the PC itself, a panel similar to the NC panel is separately provided on the PC 9a side, and this panel is operated. You may also do this by doing this.

[Effects of the invention] As can be understood from the above description of the embodiments, the present invention includes a plurality of actuators 23 for operating various operating devices 3 provided on the NC panel 21 of the NC device 1, and an operating device drive device 5a that is detachable from the NC panel 21.
and a drive signal for driving each actuator 23 in response to a control signal Si from the inspection personal computer 9a.
A motor M connected to the output section of the NC device 1 and driven by the operation of each of the operating devices 3 by each of the actuators 23; The inspection personal computer 9a includes an intermediate box 11 comprising a position calculation section 19 for processing an output signal of an encoder E linked to a motor M, and an operation section, a display section, and a communication section 17 with the intermediate box 11. It is equipped with the following.

As is clear from the above configuration, in the present invention, various actuators 23 provided in the operating device driving device 5a are used to operate various operating devices 3 provided in the NC panel 21 of the NC device 1. , it is possible to check not only the function of the NC device 1 but also the presence or absence of a failure in the operating device 3 of the NC panel 21.

Furthermore, the intermediate box 11 is equipped with a position calculation unit 19 that processes output signals of a motor M connected to and driven by the output unit of the NC device 1 and an encoder E interlocked with the motor M. Unlike the case where the output signal of the output section of the output section is directly tested, the test can be performed in a state that approximates the actual state.
