Description
Technical field
The present invention relates to numerical control maintenance testing table fault setting device, specifically is that a kind of numerical control maintenance testing table is wireless
The remote control trouble setting device is applicable in the real training experimental teaching of higher education.
Background technology
The fault of numerical control machine tool maintenance experiment table that China teaching equipment manufacturing firm produces all is to come the simulated failure point by the break-make of toggle switch on the circuit of numerically-controlled machine, and the operator adopts manual mode to stir toggle switch at panel fault is set.This set method makes the trouble spot come into plain view, and the operator is when arranging fault, and the student can see operator's setting up procedure, can guess out the trouble spot easily, such breakdown maintenance testing table does not have trainee's analysis of failure, the ability of fixing a breakdown.Therefore need convenient, the hidden device that fault is set of a kind of energy.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of numerical control maintenance testing table wireless remote control fault setting device and existing numerical control maintenance testing table and combine, fault can be set easily, the student can't see the process that fault arranges, and can't see the position, trouble spot.
The present invention realizes with following technical scheme: a kind of numerical control maintenance testing table wireless remote control fault setting device, comprise a remote control transmitter, be used for receiving the receiver of remote-control sytem of remote control transmitter information, the decoding amplification driving circuit that is connected with receiver of remote-control sytem, a plurality of faults that are connected with the decoding amplification driving circuit arrange relay; Fault arranged in the start loop that is arranged on numerically-controlled machine of normally closed contact correspondence of relay, in main shaft of numerical control machine tool control loop and the numerically-controlled machine tool rest control loop, be respectively applied to simulate start loop fault, main shaft of numerical control machine tool control loop fault and the numerically-controlled machine tool rest control loop fault of numerically-controlled machine.
Principle of work: carrying out fault when arranging, pressing the respective keys of wireless remote control emitter, the wireless remote control signal is installed in after receiving trap on the maintenance test bench set receives, and changes it into electric signal.After the driven plate circuit of electric signal amplifies, can make corresponding circuit be switched on or switched off by relay contact, numerically-controlled machine is broken down.
The invention has the beneficial effects as follows: this device can be used in combination with existing practice-training teaching device, by this
Device can arrange various faults at original practice-training teaching experiment table, and it is more convenient that fault is arranged, more hidden, thereby is conducive to practice-training teaching more; Simple in structure, be convenient to produce, make.
