This kind of lathe gravity shaft protection device that cuts off power supply unusually, including the brake of motor end, band -type brake power, band -type brake relay and auxiliary relay, the brake of motor end is used for the locking of motor gravity axis band -type brake, the band -type brake power -on is crossed the band -type brake return circuit and is connected with the brake of motor end, the band -type brake relay is connected on the band -type brake return circuit and according to the break -make in band -type brake input signal control band -type brake return circuit, auxiliary relay connects on the band -type brake return circuit and break -make and the auxiliary relay coil power of controlling the band -type brake return circuit connects on the arbitrary double -phase major loop of lathe. Above -mentioned lathe gravity shaft protection device that cuts off power supply unusually, through the detection control of auxiliary relay to lathe major loop power, improvement gravity axis motor braking's response speed to guarantee the precision of gravity axis, and processing state is to the protection demand of work piece when cutting off the power supply suddenly down.
Description
Technical field
The utility model belongs to and precision machine tool and instrument field, relates to a kind of lathe abnormal power-down gravity axis protective device specifically.
Background technology
Existing, its motor shaft of motor that the main spindle box of Digit Control Machine Tool moves up and down controls primarily of an independent circuit for controlling motor, this circuit is provided with a relay, when Digit Control Machine Tool does not work, relay remains open state, and control circuit disconnects, motor shaft cup band-type brake, when after Digit Control Machine Tool energising, relay obtains instruction closed relay again, control circuit is communicated with, and motor shaft is rotatable.When lathe emergent stopping or outside power machine suddenly, relay on circuit for controlling motor disconnects needs certain hour, motor is caused locking to shut down immediately, thus the main spindle box moved up and down by Electric Machine Control completely can be glided at the moment trace of power-off, in case of emergency may interrupt cutter head or defective work piece.
In order to solve the problem, the patent of invention of application publication number CN103490677A discloses a kind of motor emergency stop control circuit of numerically-controllmachine machine tool, comprise the relay road for controlling motor shaft rotation be arranged on circuit, it is characterized in that: also comprise the manual emergency stop button of connecting with relay, described manual emergency stop button by the total emergency stop push button of domination number controlled machine by key control.This kind of motor emergency stop control circuit of numerically-controllmachine machine tool improves the security performance of Digit Control Machine Tool by adding manual emergency stop button, but manual button need people constantly at button station, operation inconvenience and reaction speed slow.
Utility model content
In order to overcome deficiency of the prior art, the utility model provides a kind of deficiency that compensate for driver band-type brake output signal low-response when abnormal power-down, can disconnect rapidly the lathe abnormal power-down gravity axis protective device of brake loop.
For achieving the above object, the technical solution adopted in the utility model is: a kind of lathe abnormal power-down gravity axis protective device, it is characterized in that: comprise motor side brake, band-type brake power supply, band-type brake relay and auxiliary reclay, described motor side brake is used for the locking of motor gravity axis band-type brake, described band-type brake power supply to be braked with motor side by brake loop and is connected, described band-type brake relay to be connected in brake loop and to control the break-make of brake loop according to band-type brake output signal, described auxiliary reclay to be connected in brake loop and to control the break-make of brake loop, and auxiliary reclay coil power is connected on any two-phase major loop of lathe.
Further, 220-380V voltage supported by auxiliary reclay.
Further, auxiliary reclay can control brake loop two way circuit or any unidirectional circuit break-make.
From above-mentioned to description of the present utility model; compared with prior art; the lathe abnormal power-down gravity axis protective device that the utility model provides; by the detection control of auxiliary reclay to lathe main circuit power; improve the response speed of gravity axis motor braking; effectively can improve lathe when abnormal power-down; because the reasons such as driver electric capacity maintenance cause the delayed gravity axis trace caused of motor internal contracting brake to glide; thus ensure the precision of gravity axis, and under machining state during unexpected power-off to the protection demand of workpiece.
Accompanying drawing explanation

Motor side brake 1 is for by the locking of motor gravity axis band-type brake;
Band-type brake power supply 2 is braked with motor side by brake loop 21 and is connected;
Band-type brake relay 3 to be connected in brake loop 21 and to control the break-make of brake loop according to band-type brake output signal;
Auxiliary reclay 4 to be connected in brake loop 21 and to control the break-make of brake loop and auxiliary reclay coil power is connected on any two-phase major loop of lathe, 220-380V voltage supported by auxiliary reclay, and can break gravity axis band-type brake two way circuit or any unidirectional circuit in auxiliary reclay contact.
With reference to shown in Fig. 1; above-mentioned lathe abnormal power-down gravity axis protective device; by the detection control of auxiliary reclay 4 pairs of lathe main circuit powers; improve the response speed of gravity axis motor braking; effectively can improve lathe when abnormal power-down; because the reasons such as driver electric capacity maintenance cause the delayed gravity axis trace caused of motor internal contracting brake to glide, thus ensure the precision of gravity axis, and under machining state during unexpected power-off to the protection demand of workpiece
Above are only some detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
