The embodiment stated is the utility model part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's all other embodiments obtained without creative efforts, belongs to
The scope of the utility model protection.
The embodiment of the utility model provides a kind of device for detecting numerically-controlled machine tool spring and whether coming off or disconnecting.
It please refers to Fig.1, Fig. 2, Fig. 3 and Fig. 4, the utility model, which provides a kind of detection numerical control machine tool changer spring assembly, is
The no device for coming off or disconnecting, including detection device 4, the digital control system with the communication connection of detection device 4, the detection device 4
For detecting its distance with tool magazine spring assembly, the letter that detecting real-time detection device 4 is sent is encoded in the digital control system
Number PLC program and alarm PLC program.
The detection device 4 has further included stent 41, the detecting element 42 being installed on stent 41.
The detecting element 42 is electromagnetic detection element E2B-M18KN14-WZ-B1, and maximum effectively detecting distance is
16mm。
Indicator light is equiped in the detecting element 42.
The hole of M6 is beaten during specific implementation on the casting of lathe transverse axis 2, the M6*12 glasss of head hexagon socket head cap screws of stent 41 are added
M6 gaskets are fixed on the casting of numerically-controlled machine tool transverse axis 2, the fixed test element 42 on stent 41, adjust the sense of detecting element 42
It is 5mm-8mm to answer end face and the distance of tool magazine spring pull rod 51, and (distance does not limit, which can be according to the effective of sensor
Spring maximum angle range estimation in detecting distance and exchanging knives process).
The PLC program signal come off including tool magazine spring assembly 5 or disconnection detection function effectively with invalid selection
K0001.2 judges that tool magazine spring assembly 5 comes off or disconnecting warning condition selects K0019.7, tool magazine spin safe position signal
F0070.4, storage Z axis tool changing stroke section position signal G0007.4, warning output relay A0029.7.
Tool magazine spring assembly 5 comes off when program switch K0001.2 is arranged to 1 or disconnection detection function is effective.
When tool magazine spring pull rod 51 is in effective detecting distance of detecting element 42, tool magazine spring assembly 5 does not take off at this time
Fall or do not disconnect, 42 interior lamp of detecting element lights, and detecting element 42 sends signal and inputted by PLC program I/O units
Address X0001.2 obtains 1 high level, and switch X0001.2 switches are off, and relay A29.7 coils will not be powered,
Spring 5 comes off at this time or disconnecting warning information will not export, and lathe can be with normal operation；
When tool magazine spring pull rod 51 is outside effective detecting distance of detecting element 42, tool magazine spring assembly 5 comes off at this time
Or disconnect, 42 interior lamp of detecting element extinguishes, and detecting element 42 sends signal and by PLC program detecting I/O unit inputs
Address X0001.2 is reversed to low level by high level, switch X0001.2 switches in an ON state, at this time K0019.7 can have with
Lower two kinds of settings：
1. if K0019.7 is arranged to 0 state；
Spin safe position F0070.4 (preset by systematic parameter) or machine are allowed when PLC program meets tool magazine 1
Bed Z axis 3 in tool changing region when G0007.4 (preset by systematic parameter) signal be switched on, at this time and meet wherein 1 condition
Relay A29.7 coils energization output tool magazine spring assembly 5 comes off or disconnecting warning information, is touched by A29.7 relay switches
Point each axis of excitation lathe is out of service；
When PLC program be unsatisfactory for tool magazine 1 allow spin safe position F0070.4 (preset by systematic parameter) or
G0007.4 (preset by systematic parameter) signal is not switched on when machine Z-axis 3 is in tool changing region, at this time and meet wherein 1
The energization of condition relay A29.7 coils will not export tool magazine spring assembly 5 and come off or disconnecting warning information, lathe normal operation；
2. if K0019.7 is arranged to 1 state；
Represent that unconditional termination tool magazine spring assembly 5 comes off or disconnecting warning condition selects, at this time relay A29.7 lines
Circle is powered, and output tool magazine spring assembly 5 breaks warning message, and lathe terminates each axis operation immediately.
The utility model can make lathe self-test its whether tool magazine spring assembly comes off or disconnects in the process of running, it is such as resolute
It opens, by the PLC program of lathe lathe is controlled to terminate the operation of lathe immediately or terminate lathe before tool changing and run, if not
It comes off or does not disconnect, then machine tool system PLC program control lathe continues to run with, and the utility model method is solved because playing tool magazine spring
Tool changing abnormal sound caused by component is had no progeny, tool magazine cutter holder is broken, cutter is fallen in tool changing and because falling cutter product to be processed is caused to damage
It is bad, scrap, while prompt lathe operator using visual language in good man-machine interface, lathe had exception, and
Fault coverage or trouble point are directly locked, avoids to need to hinder to Machine Manufacture Business in the past and repair, wait commerce commission of machine tool plant
Engineer all scenes is sent to be studied and judged, tested, until finding out failure, repair the trouble of resulting secondary failure.This
Utility model method can reduce client to avoid the possibility for the secondary failure for coming off because of tool magazine spring assembly or generating after disconnecting
Maintenance cost, while also improve the reliability of Machine Manufacture business's product.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiment of the utility model and from above-mentioned
The limitation of embodiment, the change made under other any Spirit Essences and principle without departing from the utility model are modified, replaced
Generation, combination simplify, and should be equivalent substitute mode, are included within the scope of protection of the utility model.
