Not rounded fitting surface hydraulic controlled sleeve locking mechanism, be characterized in leaving gap between hydraulic lock axle sleeve (3) and the tangential axle sleeve of band (2), tangential axle sleeve (2) is with to be connected by A type parallel key (7) with rotating shaft (1), hydraulic lock axle sleeve (3) is screwed in lock shaft block set (4), hydraulic lock axle sleeve (3), O RunddichtringO (6) and lock shaft block set (4) form airtight pressure oil cavity (5), the pressure oil be located in lock shaft block set (4) is imported and exported A and is connected with pressure oil cavity (5), and be connected with external tapping.The utility model adds locking torque, shorten period of braking, only need the aperture changing band bastard face axle sleeve, just the hydraulic lock axle sleeve of same Dimensions can be coordinated with the rotating shaft of other Dimensionss, be conducive to series reduced in size, save manufacture cost.

Description

Not rounded fitting surface hydraulic controlled sleeve locking mechanism

Technical field

The utility model relate to a kind of rotate axial workpiece braking, locking and positioning device, particularly a kind ofly under action of hydraulic force, there is by resilient metal member the not rounded fitting surface hydraulic controlled sleeve locking mechanism that resiliently deformable realizes locking.

Background technique

In a lot of mechanical structure, there is such situation: a rotating shaft, needs clockwise and anticlockwise in certain moment, need fixing in another moment, this relates to rotating shaft locking and positioning device.

For lathe, 5-shaft linkage numerical control lathe is made up of three straight-line feed axles and two swivel feeding axles, need swivel feeding axle is located and locks under some processing operating mode, the normal action having come locking and location by duplex fluted disc or three fluted discs and hydraulic lock axle sleeve at present, but fluted disc tooth calibration, although locking torque is larger, period of braking is short, but can not realize locating at any angle and locking, and easy to wear; Locate at any angle although hydraulic lock axle sleeve achieves and lock, compare fluted disc class location locking mechanism, its locking torque is relatively little, and period of braking is relatively long.

Model utility content

Goal of the invention of the present invention is to provide a kind of hydraulic locking mechanism, little with the hydraulic lock axle sleeve locking torque solved in the past, the problem that period of braking is long, solve simultaneously a kind of size hydraulic lock axle sleeve can only with a kind of rotating shaft of size with the use of problem.

The technological scheme that the utility model provides is: this not rounded fitting surface hydraulic controlled sleeve locking mechanism, be characterized in comprising rotating shaft 1, be with tangential axle sleeve 2, hydraulic lock axle sleeve 3, lock shaft block set 4, pressure oil cavity 5, O RunddichtringO 6, A type parallel key 7, bastard face 8, A imported and exported by pressure oil, wherein hydraulic lock axle sleeve 3 and be with between tangential axle sleeve 2 and leave gap, tangential axle sleeve 2 is with to be connected by A type parallel key 7 with rotating shaft 1, hydraulic lock axle sleeve 3 is screwed in lock shaft block set 4, hydraulic lock axle sleeve 3, O RunddichtringO 6 and lock shaft block set 4 form airtight pressure oil cavity 5, the pressure oil be located in lock shaft block set 4 is imported and exported A and is connected with pressure oil cavity 5, and be connected with external tapping.

Hydraulic lock axle sleeve 3 does not directly contact with rotating shaft 1 after being out of shape, but contacts with the tangential axle sleeve 2 of the band existed between hydraulic lock axle sleeve 3 and rotating shaft 1, and this band bastard face axle sleeve 2 is connected by parallel key 7 with rotating shaft 1.

Axial direction with tangential axle sleeve 2 also exists multiple bastard face 8 paralleled to the axis.

With the wear-resistant sleeve that tangential axle sleeve 2 entirety is made for the wear-resisting and tin bronze of good springiness.

Compared with prior art, the beneficial effects of the utility model: under the effect of pressure oil, there is the hydraulic lock axle sleeve generation resiliently deformable of excellent resilient properties, hydraulic lock axle sleeve can produce friction lock moment of torsion with the cylinder contacts face place of band bastard face axle sleeve, along with pressure increase, hydraulic lock axle sleeve is just greater than just to the resiliently deformable at cylndrical surface place to the distortion of bastard face place, the nonuniformity of this distortion can produce a mechanical braking effect at bastard face place to band bastard face axle sleeve, this mechanical braking effect not only adds locking torque, and shortens period of braking; Only need the aperture changing band bastard face axle sleeve simultaneously, just the hydraulic lock axle sleeve of same Dimensions can be coordinated with the rotating shaft of other Dimensionss, be conducive to series reduced in size, save manufacture cost.

Embodiment

Below the technical solution of the utility model is described in detail, but protection domain of the present utility model is not limited to described embodiment.

As shown in Figure 1, the invention provides a kind of not rounded fitting surface hydraulic controlled sleeve locking mechanism, this mechanism comprises: rotating shaft 1, band bastard face 8 axle sleeve 2(as shown in Figure 3), hydraulic lock axle sleeve 3(as shown in Figure 4), lock shaft block set 4, pressure oil cavity 5, O RunddichtringO 6, A type parallel key 7, bastard face 8, pressure oil import and export A; Leave gap between hydraulic lock axle sleeve 3 and band bastard face axle sleeve 2, band bastard face axle sleeve 3 is connected by A type parallel key 7 with rotating shaft 2, and hydraulic lock axle sleeve 3 is screwed in lock shaft block set 4; Hydraulic lock axle sleeve 3, O RunddichtringO 5 form airtight pressure oil cavity 5 with lock shaft block set 4; The pressure oil be located in lock shaft block set 4 is imported and exported A and is connected with pressure oil cavity 5, and is connected with external tapping.

When rotating shaft 1 needs to lock, oil pressure in pressure oil cavity 5 rises rapidly, make hydraulic lock axle sleeve 3 that resiliently deformable occur, eliminate the gap between hydraulic lock axle sleeve 3 and band bastard face axle sleeve 2, hydraulic lock axle sleeve 3 produces friction torque with the cylinder contacts face of band bastard face axle sleeve 2, hydraulic lock axle sleeve 3 applies a mechanical braking effect to the bastard face 8 on band bastard face axle sleeve 2 simultaneously, and friction torque and mechanical braking effect make rotating shaft 1 brake rapidly, and maintain the lock status.

When rotating shaft 1 does not need to lock, pressure oil pressure release in pressure oil cavity 5, hydraulic lock axle sleeve 3 recovers gap with band bastard face axle sleeve 2, and band bastard face axle sleeve is by the effect of hydraulic lock axle sleeve 3, and thus, rotating shaft 1 drive band bastard face axle sleeve 2 normally rotates.
