Background technique
Now existing many kinds of gyrodamping devices are disclosed, and under simple scenario, rotor is made of a cylinder, and this cylinder is rotating to be contained in the cylinder space, in resisting medium and/or the elastic device annular space between these parts.
Chinese invention patent application " rotating cylinder type oil damper ", application number is 03147661.9, it discloses a kind of rotating cylinder type oil damper, in this damper, the flowing fluid ratio of viscosity such as silicone oil, its rotation of damping around axle.Described damper comprises a shell, and this shell has concentrically with respect to one another an inner cylinder and an outer cylinder that is provided with and is formed on a annular space between described inner cylinder and the outer cylinder, includes viscous liquid in this annular space; A cylindric rotor is contained in the described shell and is subjected to the damping function of described viscous liquid; An annular seal element is used to prevent that viscous liquid from leaking; And a ring cover, be independent of described rotor setting and be installed on the described shell, described rotor and described seal element are remained in the described shell.
The rotation motion of cold rolling machine tool chief axis adopts damper assurance synchronization accuracy also not see at home and abroad.At present, the synchronization accuracy of the main shaft gyration motion of cold rolling lathe is guaranteed by accuracy of manufacturing fully, but foozle is an objective reality, each main shaft circumferential position changes when causing motion of main shaft to be subjected to the impact of power or stop motion, thereby be difficult to accomplish each main shaft synchronism stability operation, be difficult to guarantee the precision and the quality of part processing.
The model utility content
Technical problem to be solved in the utility model provides the synchronous damper of a kind of main shaft, solves main shaft because the caused velocity variations of variation of load guarantees that the stable of each motion of main shaft with synchronously, improves the indexing accuracy of processing profiled parts effectively.
The technological scheme that the synchronous damper of main shaft described in the utility model is taked, it comprises:
A housing is fixedly connected on the positioning link; Its excircle is equipped with an outlet valve, and outlet valve is connected with sealing gasket, also has a fluid input;
A rotor, i.e. the collar bush of fixedlying connected with main shaft, it can rotate in housing;
It is characterized in that: also comprise
An adjustable damping device is arranged in the space that housing and collar bush form, and is positioned on the housing, and its internal surface and a side contact with collar bush;
A fluid transmission means, cavity that is formed by housing, collar bush and adjustable damping device and the fluid input that is communicated with it are formed.
The synchronous damper of described main shaft is characterized in that: described adjustable damping device is a friction ring.
The synchronous damper of described main shaft is characterized in that: be provided with a piston ring in the described cavity, it contacts with friction ring.
The synchronous damper of described main shaft is characterized in that: with straight pin friction ring is positioned on the housing, with Cock screw fixed cylinder pin;
The synchronous damper of described main shaft is characterized in that: collar bush is fixedlyed connected with main shaft by connecting key.
A kind of chipless cold rolling lathe comprises a body, and annex and some main shafts is characterized in that: the synchronous damper of above-mentioned main shaft is housed on the described main shaft.
That is to say that in the preferred synchronous damper of main shaft, the collar bush device is in housing, friction ring is positioned at the space of collar bush and housing formation, and straight pin is positioned at friction ring on the housing, and fixes with Cock screw; Piston ring is installed in the cavity of collar bush, housing and friction ring formation, and described cavity is communicated with fluid input; Outlet valve and sealing gasket are loaded on the excircle of housing, and damper is fixed on the main shaft link.
The synchronous damper of above-mentioned main shaft is contained in respectively on each main shaft, and it produces damping function during work, can eliminate because the motion of main shaft wild effect that the impact of motion and fit up gap cause realizes the synchronous of motion of main shaft.
After chipless cold rolling lathe is loaded onto the synchronous damper of described main shaft, make the axis feeding velocity-stabilization, calibration is accurate, the workpiece precision height that obtains, high conformity.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is further specified.
Fig. 1 is the plan view of the synchronous damper of the utility model main shaft;
Fig. 2 is the B-B phantom of Fig. 1;
Fig. 3 is the A-A phantom of Fig. 1.
Embodiment
The synchronous damper of main shaft described in the utility model, it comprises:
A housing 6 is fixedly connected on the positioning link; Its excircle is equipped with an outlet valve 12, and outlet valve 12 is connected with sealing gasket 11; Also have a fluid input 4;
A rotor, the collar bush 2 of promptly fixedlying connected with main shaft, it can rotate in housing 6;
Also have:
Piston ring 8 and friction ring 3 cavity 5 that housing 6 and collar bush 2 form of packing into, cavity 5 is communicated with fluid input 4; Collar bush 2 runs through the endoporus of housing 6 and friction ring 3, makes the external diameter of collar bush 2 and the internal diameter of housing 6 and friction ring 3 keep uniform gap.Collar bush 2 is fixedlyed connected with main shaft by connecting key 7.Straight pin 10 is behind friction ring 3 and housing 6 location, with Cock screw 9 it tightened.An outlet valve 12 is equipped with in housing 6 tops, and its effect is: after two main shafts quit work, need carry out rotating exhaust when the tooth position is adjusted to workpiece, friction ring 3 and collar bush 2 are thrown off, two main shafts can arbitrarily carry out the clockwise and anticlockwise rotation, carry out the adjustment of tooth position.A sealing gasket 11 is housed, fluid leaks when preventing exhaust below the outlet valve 12.1 fixation of screw, with the damping device that assembles be fixed on the main shaft link on, carry out work with the motion of lathe main shaft.
The working state of the synchronous damper of main shaft described in the utility model is: behind the pump work of pressurizing system, the fluid of transmission pressure enters housing 6 top-right fluid inputs 4 by the pressure valve of setting pressure, cavity 5 is communicated with fluid input 4, fluid just acts on the piston ring 8 in the cavity 5, thereby promoting friction ring 3 fits with the right side of collar bush 2, play damping function, make the main shaft that described damper is housed realize being synchronized with the movement.
