Abstract
The invention relates to an automatic hydraulic lock block which comprises a lock block body, a piston rod, a disk spring, a seal ring, a press cover, a fixed screw, an oil joint, a puller block, a guide rail and the like. Hydraulic oil enters the lock block body from pipe joints on both sides of the lock block and then enters an oil cavity formed from the lock block body, the piston rod and the seal ring through an oil passage in the lock block body through electrical control, the piston rod is driven to move by means of oil pressure, the movement of the piston rod enables the disk spring to be compressed to drive the puller block to move, and thus, the purpose of loosing the guide rail by the lock block is realized. During shutdown power-off, because the hydraulic system stops supplying oil, the pressure of the oil cavity formed from the lock block body, the piston rod and the seal ring is reduced, the disk spring supports against the piston rod tightly due to the action of spring force, the piston rod drives the puller block to move, and thus, the purpose of locking the guide rail is realized.
Description
Technical field
Patent of the present invention is an automatic hydraulic latch segment device, this device can be installed on the feed arrangement of inclination, vertical axis of various Digit Control Machine Tools, special purpose machine tool, the line slideway that is used for locking feed shaft when outage is stopped, can prevent the downslide of feed arrangement, the demand of the outage brake locking in the time of particularly can satisfying feed arrangement and be linear electric motors and drive.
Background technology
At present, on the feed arrangement of domestic inclination at various Digit Control Machine Tools, vertical axis, the locking device of application mostly is electromagnetic brake device or mechanical gripping means, and the electromagnetic brake device is mainly used in the locking gyroaxis, when feed shaft is linear electric motors, then can't lock; Mechanical grip is complex structure then, and volume is big, and cramping is counted few, discontinuity, and machining is easy to generate vibrations, clamping and release, manually-operated, conversion time is long, can not realize lathe, parts automation, the manufacturing cost height; For the feed system of plant equipment is that linear electric motors then require to have when driving and clamp require electromagnetic brake device or mechanical gripping means automatic, quick, even, firm, simple in structure, that volume is little and all can't realize.
Summary of the invention
The object of the present invention is to provide a kind of automatic hydraulic latch segment device, can accomplish the line slideway of automatic, quick, even, firm locking feed arrangement, the accurate positioning requirements that is used for feed arrangement when outage is stopped, the outage brake demand in the time of particularly can satisfying feed shaft and be linear electric motors.
For achieving the above object, the technical solution used in the present invention is as follows:
Automatic hydraulic latch segment device of the present invention comprises the locking block, is provided with the oil cylinder pilot hole in the both sides of locking block, and piston rod is packed in the oil cylinder pilot hole, forms seal oil chamber by oil cylinder pilot hole, the piston rod of locking block; Screw thread place at piston rod is provided with withstanding tight block, and disk spring is packed in the oil cylinder pilot hole of locking block, and gland is fixed on the locking block, and makes disk spring have certain pretightning force, is provided with joint in the side of locking block.
The present invention preferably is provided with sealing ring in the seal groove at piston rod, form seal oil chamber by oil cylinder pilot hole, sealing ring, the piston rod of locking block.
When hydraulic oil entered the oil circuit of locking block by joint, oil pressure made piston rod drive withstanding tight block and moves outward, makes disk spring stressed, and compression is adjacent to gland, makes withstanding tight block unclamp guide rail; When fuel cut-off and off-load, disk spring moves inward by the elastic force promotion piston rod of self, and piston rod drives withstanding tight block 8 and holds out against guide rail, plays the purpose of locking guide rail.
This automatic hydraulic latch segment device comprises compositions such as locking block, piston rod, disk spring, sealing ring, gland, hold-down screw, oily joint, withstanding tight block, guide rail; Hydraulic oil is by electrical control, enter in the locking block from the pipe joint of the two sides of latch segment, by the asphalt channel in the locking block, enter into the oil pocket of forming by locking block, piston rod, sealing ring, promoting piston rod by oil pressure moves, piston rod moves and makes disk spring compression and drive withstanding tight block move, thereby realizes the purpose that latch segment unclamps guide rail; When stopping outage, because the hydraulic system fuel cut-off, the pressure in the oil pocket of being made up of locking block, piston rod, sealing ring reduces, and disk spring is owing to the effect of spring force holds out against piston rod, make piston rod drive withstanding tight block and move, realize the purpose of locking guide rail.
The computing formula of clamping force is as follows:
Clamping force: F1=2(D/2)
2π p (N)
Wherein: D clamping piston diameter, (m)
P fluid pressure, (Pa)
Two oil cylinder oil circuits of locking block communicate, and oil-feed simultaneously, off-load simultaneously realize synchronization action.
Owing to adopted technique scheme, the present invention to have following advantage:
1, this device clamping force is clamped, is unclamped by hydraulic pressure transfer, can be realized automatically by electrical control.
2. can arbitrarily arrange withstanding tight block as required, be fit to the hydraulic pressure auto lock of various guide rails.
3. overall structure is simple in structure, volume is little, can satisfy less space requirement.
4. the cramping piston is by hydraulic control, and oil pocket links to each other, concurrently-acting, and the cramping time is short.
5. this device is produced part, only forms low cost of manufacture by locking block, piston rod, gland, withstanding tight block.
