Background technology
Numerical control gear milling machine YKD2280 cage chair servomotor is in the time of debugging lathe, when having offset at the cutterhead above cage chair and during in manual adjustment state, now press the power-off of " scram button " equipment cage chair servomotor, work cage chair is not because center of gravity is on center line, under Gravitative Loads, rotate, cutterhead offset is larger, fallback distance is longer, now product and knife are in engagement machining state, cause breaking cutterhead cutter head and product workpiece simultaneously, cause lathe cutter spindle and work spindle to be badly damaged, make lathe cutter spindle precise decreasing, a knife loses more than 3,000 yuan.After cutter shaft knife and workpiece break simultaneously, need renew cutter and toolsetting processing to lathe, and tool setting after tool changing, check whether lathe bias moves, whether the workpiece degree of depth moves, whether move in workpiece position of wheel, the whether displacement of workpiece teeth groove, also need to check the work such as whether contact zone and gap qualified, greatly increasing cost of labor expense increases.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of numerical control gear milling machine cage chair servomotor self-locking device is provided, and can the in the situation that of power-off, effectively protect cage chair main shaft knife and workpiece, reduces the loss.
The technical solution of the utility model is: a kind of numerical control gear milling machine cage chair servomotor self-locking device, self-locking device comprises fixed head, portable plate and a magnetic valve, described fixed head is mounted by means of bolts on the lathe of numerical control gear milling machine, parallel with the motor shaft of numerical control gear milling machine servomotor, one end of described portable plate and one end of fixed head are hinged, the middle part of portable plate is installed one and is adjusted bolt, this adjustment bolt extends towards the motor shaft of numerical control gear milling servomotor through fixed head, adjusting bolt extends cover on the screw rod of fixed head and has spring, the screw rod end of adjusting bolt is fixedly connected with a brake disc, between the motor shaft of this brake disc and numerical control gear milling servomotor, leave distance, the valve body of described magnetic valve is fixedly mounted on portable plate, the magnetic core push rod of magnetic valve is connected towards fixed head and with fixed head, make the interval between portable plate and fixed head adjustable.
Described adjustment bolt is arranged on the middle part of portable plate by an adjusting nut.
Described brake disc adapts with motor shaft near an end face of numerical control gear milling servomotor motor shaft is curved.
On described portable plate, the position of corresponding bolt is provided with nut resigning hole.
Adopt technique scheme, by regulating the interval between portable plate and fixed head, make the distance between brake disc and the motor shaft of numerical control gear milling servomotor adjustable.In the time that magnetic valve is switched on, the magnetic core push rod of magnetic valve extends, interval between portable plate and fixed head is increased, drive brake disc away from numerical control gear milling servomotor motor shaft Compress Spring, now numerical control gear milling servomotor motor shaft freely rotates, numerical control gear milling machine is normally worked, in the time of unexpected power failure, the magnetic core push rod of magnetic valve shortens, under the effect of spring, brake disc moves locking motor shaft towards the motor shaft of numerical control gear milling servomotor, by frictional force, motor shaft cannot be rotated, effectively protection cage chair main shaft knife and workpiece, ensure the precision of lathe cutter spindle and work spindle, extend the service life of numerical control gear milling machine.
Described adjustment bolt is arranged on the middle part of portable plate by an adjusting nut, regulate by threaded engagement between adjusting nut and adjustment bolt, can effectively finely tune the distance between brake disc and the motor shaft of servomotor, simple in structure, easy to use.
Described brake disc adapts with motor shaft near an end face of numerical control gear milling servomotor motor shaft is curved, so effectively ensure the contact area between brake disc and servomotor motor shaft, in braking procedure, contact area is large, and frictional force is larger, good braking effect.
Be further described below in conjunction with the drawings and specific embodiments.
Brief description of the drawings
Fig. 1 is mounting structure schematic diagram of the present utility model;
Fig. 2 is self-locking device structural representation of the present utility model.
In accompanying drawing, 1 is portable plate, and 2 is fixed head, and 3 is magnetic valve, and 4 is lathe, and 5 for adjusting bolt, and 6 is spring, and 7 is brake disc, and 8 is adjusting nut.
Detailed description of the invention
Referring to Fig. 1 and Fig. 2, a kind of numerical control gear milling machine cage chair servomotor self-locking device, self-locking device comprises fixed head 2, portable plate 1 and a magnetic valve 3, the present embodiment, the thickness of described fixed head is 10mm, length is that 260mm, width are 75mm, and the thickness of portable plate is that 10mm, length are that 250mm, width are 75mm.Described fixed head 2 is mounted by means of bolts on the lathe 4 of numerical control gear milling machine, parallel with the motor shaft of numerical control gear milling machine servomotor, the present embodiment, fixed head 2 is fixedly mounted on the lathe of numerical control gear milling machine by two M6 bolts, the length direction of fixed head 2 is parallel with the motor shaft of servomotor, width vertically upward, perpendicular to the lathe of numerical control gear milling machine.One end of one end of described portable plate 1 and fixed head 2 is hinged, and on portable plate 1, the position of corresponding M6 bolt is provided with nut resigning hole.The middle part of portable plate 1 is installed one and is adjusted bolt 5, the present embodiment, described adjustment bolt 5 is arranged on the middle part of portable plate 1 by an adjusting nut 8, this adjustment bolt 5 extends towards the motor shaft of numerical control gear milling servomotor through fixed head 2, adjusting bolt 5 extends cover on the screw rod of fixed head 2 and has spring 6, the screw rod end of adjusting bolt 5 is fixedly connected with a brake disc 7, the present embodiment, described brake disc 7 is fixed by welding on the end of adjusting bolt screw rod, brake disc adapts with motor shaft near an end face of numerical control gear milling servomotor motor shaft is curved, between this brake disc 7 and the motor shaft of numerical control gear milling servomotor, leave distance.The valve body of described magnetic valve 3 is fixedly mounted on portable plate 1, and the magnetic core push rod of magnetic valve 3 is connected towards fixed head and with fixed head 2, makes the interval between portable plate 1 and fixed head 2 adjustable.
