Description
Technical Field
The application belongs to the field of machining, and particularly relates to a groove ring type hydraulic locking device for a rotating shaft.
Background
In the process of machining a five-axis machine tool, machining is often required under the condition that an A/C rotating shaft is locked, so that the rotating shaft locking device is widely applied to the five-axis machine tool.
The positioning and clamping mechanism at any position adopted in the market at present is mainly a disc type positioning and clamping mechanism. The disc type positioning and clamping mechanism adopts brake pads to brake and clamp, and for a rotating shaft, the brake pads are required to be respectively arranged on the upper end surface and the lower end surface of the rotating shaft, so that the brake and the clamping can be effectively performed. The disc type positioning and clamping mechanism has the following defects: there are many mechanical parts and installation procedures are cumbersome, and there may be situations where the parts cannot be completely disengaged when the brake is released.
Disclosure of Invention
In order to overcome the problems in the prior art, the groove ring type hydraulic locking device for the rotating shaft is compact in structure, convenient to install, low in cost, stable and reliable in positioning and clamping and quick in brake response relieving.
In order to achieve the technical problem, the technical scheme adopted by the application is as follows:
a groove ring type hydraulic locking device for a rotating shaft is characterized in that: the oil cavity locking device is characterized by comprising a locking sleeve, wherein a groove ring oil cavity inner ring is installed in an outer wall ring groove of the locking sleeve, O-shaped sealing rings are respectively embedded in ring grooves at two ends of the groove ring oil cavity inner ring, a groove ring oil cavity outer ring is arranged outside the locking sleeve, and the O-shaped sealing rings are arranged between the groove ring oil cavity inner ring and the groove ring oil cavity outer ring.
The outer wall of the outer ring of the groove ring oil cavity is connected with a hinged pipe joint.
The hinged pipe joint is in threaded connection with the outer ring of the groove ring oil cavity.
The middle part of the outer ring of the groove ring oil cavity is provided with a connecting ring structure of a vertical structure, and the connecting ring structure is used for being connected with the rotating shaft box body.
The working principle of the application is as follows:
when the locking device works, hydraulic oil with rated pressure is introduced from the hinged pipe joint, and the inner ring of the oil cavity of the groove ring transmits radial pressure to the locking sleeve under the action of the oil pressure, so that the locking sleeve is contracted inwards until the rotating shaft is locked. When the oil pressure passes through articulated coupling release back, the locking cover is at elastic deformation effect reconversion down, and the device gets back to the unclamped state.
The application has the advantages that:
the hydraulic control system can realize quick locking of the rotating shaft, is simple in mechanical structure and convenient to install, adopts single oil circuit control, and is simple in hydraulic control loop and low in implementation cost; the hydraulic locking device adopts a standard O-shaped ring and a hinged pipe joint, and has good universality.

In the figure: 1-locking sleeve, 2-groove ring oil cavity inner ring, 3-O-shaped sealing ring, 4-groove ring oil cavity outer ring, 5-hinged pipe joint, 6-rotating shaft box body, 7-supporting bearing and 8-rotating shaft.
Detailed Description
Example 1
The utility model provides a groove ring formula hydraulic locking device for rotation axis, its includes lock sleeve 1, install groove ring oil pocket inner ring 2 in the outer wall annular of lock sleeve 1, inlay O shape sealing washer 3 in the annular at groove ring oil pocket inner ring 2 both ends respectively, lock sleeve 1 is provided with groove ring oil pocket outer loop 4 outward, O shape sealing washer 3 sets up between groove ring oil pocket inner ring 2 and groove ring oil pocket outer loop 4. When the locking device works, hydraulic oil with rated pressure is introduced from the hinged pipe joint 5, and the inner ring 2 of the oil cavity of the groove ring transmits radial pressure to the locking sleeve 1 under the action of the oil pressure, so that the locking sleeve 1 is contracted inwards until the rotating shaft 8 is locked. When the oil pressure passes through articulated coupling 5 release back, the original state is resumeed to lock sleeve 1 under the effect of elastic deformation power, and the device gets back to and loosens the state. The locking device can realize the quick locking of the rotating shaft 8, has simple mechanical structure and convenient installation, adopts the control of a single oil circuit, and has simple hydraulic control loop and lower implementation cost; the hydraulic locking device adopts a standard O-shaped ring and a hinged pipe joint 5, and has good universality.
Example 2
The utility model provides a groove ring formula hydraulic locking device for rotation axis, its includes lock sleeve 1, install groove ring oil pocket inner ring 2 in the outer wall annular of lock sleeve 1, inlay O shape sealing washer 3 in the annular at groove ring oil pocket inner ring 2 both ends respectively, lock sleeve 1 is provided with groove ring oil pocket outer loop 4 outward, O shape sealing washer 3 sets up between groove ring oil pocket inner ring 2 and groove ring oil pocket outer loop 4.
The outer wall of the groove ring oil cavity outer ring 4 is connected with a hinged pipe joint 5. The hinged pipe joint 5 is in threaded connection with the groove ring oil cavity outer ring 4. The middle part of the outer ring 4 of the groove ring oil cavity is provided with a connecting ring structure with a vertical structure, and the connecting ring structure is used for being connected with a rotating shaft box body 6.
The rotating shaft 8 is arranged in the locking sleeve 1, then the hydraulic oil cavity outer ring is connected with the rotating shaft box body 6 through screws, in the installation process, the locking sleeve 1 and the rotating shaft 8 are ensured to be coaxial, and the rotating shaft box body 6 is connected with the rotating shaft 8 through the supporting bearing 7.
When the locking device works, hydraulic oil with rated pressure is introduced from the hinged pipe joint 5, and the inner ring 2 of the oil cavity of the groove ring transmits radial pressure to the locking sleeve 1 under the action of the oil pressure, so that the locking sleeve 1 is contracted inwards until the rotating shaft 8 is locked. When the oil pressure passes through articulated coupling 5 release back, the original state is resumeed to lock sleeve 1 under the effect of elastic deformation power, and the device gets back to and loosens the state.
The locking device can realize the quick locking of the rotating shaft 8, has simple mechanical structure and convenient installation, adopts the control of a single oil circuit, and has simple hydraulic control loop and lower implementation cost; the hydraulic locking device adopts a standard O-shaped ring and a hinged pipe joint 5, and has good universality.
