Abstract
The invention relates to a hydraumatic disc-type locking device for a swing mechanism of a machine tool. A rotating shaft is fixedly provided with a locking disc; and the upper and lower sides of the locking disc are respectively provided with a hydraumatic transforming disc and a fixed disc which are fixed on a box body through bolts. By adopting the hydraumatic disc-type circumferential plane locking device, contact face between an upper plane and a lower plane is added in the locking device, improves the locking force, and ensures that the swing mechanism not only can realize automatic locking, but also increases the reliability and stability of the locking device.
Description
Technical field
The present invention relates to a kind of mechanical device, relate in particular to a kind of Hydraumatic disc-type locking device for swing mechanism of machine tool.
Background technology
The mechanical locking device of machine tool rotary mechanism can have various ways, as screw tighten, bite type holds tightly, also has fluid pressure type radially to lock, perhaps form such as fluid pressure type wedge locking.These locking forms all have limitation, and screw is tightened, bite type is held tightly, generally is used for the simple mechanism of hand, can not be used for automatic locking mechanism.Fluid pressure type is radially locked, and perhaps fluid pressure type wedge locking form can be used for automatic locking mechanism, but radially locks the mechanism that is applicable to the external diameter direction; And the fluid pressure type wedge that is used for planar fashion is locked, and limited because of the contact-making surface on wedge and plane, its coupling mechanism force is little, is not suitable for the bigger gyroaxis mechanism of deadweight.
Summary of the invention
Main purpose of the present invention is: solve the locking problem that bigger deadweight slew gear is arranged, thereby develop a kind of increase flat contact surface, improve coupling mechanism force, make slew gear can implement auto lock, and the reliable and stable Hydraumatic disc-type locking device for swing mechanism of machine tool of coupling mechanism force.
The present invention improves the main technical schemes of coupling mechanism force: a kind of Hydraumatic disc-type locking device for swing mechanism of machine tool, form by gyroaxis, bearing, locking plate, hydraulic system, indexing mechanism etc., indexing mechanism is connected with bearing, bearing is contained on the gyroaxis, it is characterized in that: be fixed with locking plate on the gyroaxis, locking plate two sides up and down is equipped with hydraulic pressure texturising disc and fixed disk, and hydraulic pressure texturising disc and fixed disk keep certain clearance with locking plate respectively, and nationality is bolted on the casing.
Technique scheme of the present invention can also be further perfect:
As preferably, the pressure oil of described hydraulic system is through fixed disk and the connection of hydraulic pressure texturising disc inner chamber, and described hydraulic pressure texturising disc is the disc of thin-wall construction.
As preferably, the operating pressure of described hydraulic system is 2.5-12MPa.
The invention has the beneficial effects as follows: the hydraulic pressure texturising disc is the disc of thin-wall construction, adopts hydraulic disk circumferential plane locking device, has increased the contact-making surface of last lower plane, has improved coupling mechanism force.What make slew gear can not only realize auto lock, and has increased the reliability and stability of retaining mechanism.

Description of reference numerals: gyroaxis 1, bearing 2, locking plate 3, hydraulic system 4, indexing mechanism 5, hydraulic pressure texturising disc 6, fixed disk 7, casing 8.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, technical solution of the present invention is described in further detail.
Hydraumatic disc-type locking device for swing mechanism of machine tool as shown in Figure 1 is equipped with internal tooth floating bearing 2 on the gyroaxis 1, bearing 2 models are: ROLLIX/07.0380.01.ZZ10, bearing outer ring nationality screw M12 is fixed on the casing 8.Locking plate 3 nationality screw M8 are fixed on the gyroaxis 1.Fixed disk 7 is equipped with in locking plate 3 tops, and hydraulic pressure texturising disc 6 is equipped with in the below, makes fixed disk 7 and hydraulic pressure texturising disc 6 all and maintain the 0.03-0.05mm gap between the locking plate 3.Fixed disk 7 and hydraulic pressure texturising disc 6 nationality screw M8 are fixed on the casing 8.Hydraulic system 4 is connected by pipeline and fixed disk 7, makes hydraulic oil enter hydraulic pressure texturising disc 6 cavitys, and hydraulic system working pressure is about 65Mpa.
Operation principle: after the gyroaxis calibration is finished, fluid pressure oil enters texturising disc 6 cavitys, make hydraulic pressure texturising disc 6 produce distortion, the circumference working face of hydraulic pressure texturising disc is pressed to locking plate 3, locking plate 3 is subjected to the restriction of fixed disk 7 again, metamorphosis power and reaction force produce coupling mechanism force, have guaranteed that the reliable lock of locking plate 3 and gyroaxis 1 thereof is stable.
The machine tool rotary organization hydraulic pressure disc type circumferential plane locking device that the present invention adopts uses on product MKB7025 numerical control track slab grinder, reliable lock, and effect is obvious.
The described specific embodiment of this specification only is illustrating technical solution of the present invention.The technical staff of the technical field of the invention may be to the instantiation of above-mentioned description, do some and revise to replenish or adopt the similar techniques scheme to substitute, but can not depart from the initiative spirit of technical solution of the present invention or surmount the defined scope of this programme claims.
