Abstract
The invention discloses a rotary braking device which comprises a body, an annular elastic tube and a friction ring, wherein the body is annular, and an annular groove extending in circumference direction is also formed on the body; the annular elastic tube is sleeved in the groove; the inner part of the annular elastic tube can be filled with a pressure medium; the friction ring is sleeved on the body in a manner of pressing against the annular elastic tube and can elastically expand or shrink along the radial direction of the body; and the expansion or shrinkage of the friction ring is controlled through controlling the pressure of the pressure medium filled into the annular elastic tube. According to the rotary braking device, when the high pressure medium is filled into the annular elastic tube, the annular elastic tube is enabled to expand outwards or shrink inwards by controlling the pressure of the high pressure medium, so that the friction ring is extruded to expand outwards or shrink inwards, so as to hold the braked rotary sleeve or rotary shaft tightly. The annular elastic tube shrinks naturally when the high pressure medium is unloaded, so that the braked rotary sleeve or rotary shaft is loosened by the friction ring.
Description
Technical field
The present invention relates to machinery, relate in particular to a kind of device that is used to brake.
Background technique
Some have in the machinery etc. of revolving structure in existing machine tool etc.; What braking was adopted is to adopt hydraulic pressure installation, calutron etc. usually, and physical dimension is bigger, under the relatively stricter situation of some spatial limitation; Braking device such as hydraulic pressure installation, calutron has just been installed not; Such as the braking of two swing axiss in the milling head of Double swing head, the space is very narrow and small, and general braking device just can not be installed at all.Brake device structure of the present invention is compact, and stopping power is strong, is fit to the rotary braking in the small space.
Summary of the invention
The object of the present invention is to provide a kind of braking rapid, the higher rotary braking device of efficient.
A kind of rotary braking device of the present invention comprises:
Body, this body are annular, on said body, also are formed with the annular recess along extending circumferentially;
The cyclic spring pipe is set in the said groove, but charged pressure medium in the said cyclic spring pipe;
Dead turn is set on the said body with the mode that is pressed against on the said cyclic spring pipe, and said dead turn can be along the radial elastic dilation or the contraction of said body;
Charge into the pressure of the pressure medium in the said cyclic spring pipe through control, control the expansion or the contraction of said dead turn.
Preferably, said body is fastened by two annulars, half dish and forms.
Preferably, said groove is formed on the inner peripheral surface of said body, and said dead turn is set in the ring of said body.
Preferably, said groove is formed on the outer peripheral surface of said body, and said dead turn is set in outside the ring of said body.
Preferably, the bellows of said cyclic spring Guan Weike elastic dilatation.
Preferably, be formed with first stop tooth at the periphery of said dead turn, on said body, be formed be meshed with said first stop tooth so that second stop tooth that the not said relatively body of said dead turn rotates.
Preferably, said high-pressure medium is pressurized gas or highly pressurised liquid.
The present invention is when charging into high-pressure medium in the cyclic spring pipe, through the pressure of control high-pressure medium, so that the cyclic spring pipe expands outward or toward interior contraction, the extrusion friction circle expands or toward interior contraction outward, thereby holds revolution sleeve or the turning axle that is braked tightly.When unloading during high-pressure medium, the cyclic spring pipe shrinks naturally, thus the revolution sleeve or the turning axle that dead turn are unclamped be braked.

Embodiment
Embodiment 1
Like Fig. 1, shown in 2, the present invention includes: body 1, cyclic spring pipe 2 and dead turn 3, body 1 are annular, and in the present embodiment, body 1 is fastened and forms, and be fixedly installed togather through screw 4 by the first half dishes 11 of two annulars, the second half dishes 12.On body 1, also be formed with the annular recess 5 along extending circumferentially, in the present embodiment, annular groove 5 is arranged on the inner peripheral surface of body 1.Cyclic spring pipe 2 is set in the groove 5, but cyclic spring pipe 2 is interior through being opened in the opening 21 charged pressure media on the cyclic spring pipe 2, and for example highly pressurised liquid certainly, also can be pressurized gas.Dead turn 3 is set on the body 1 with the mode that is pressed against on the cyclic spring pipe 2, and dead turn 3 can be along the radial elastic dilation or the contraction of body 1.
In addition, as shown in Figure 2, be formed with first stop tooth 31 at the periphery of dead turn 3, on body 1, be formed be meshed with first stop tooth 31 so that dead turn 3 second stop tooth 13 that rotates of body 1 relatively.Like this, when dead turn 3 shrank and holds the turning axle 6 that is braked tightly, dead turn 3 can not driven and circumferentially rotate by turning axle 6, to guarantee braking effect.
In addition, as shown in Figure 3, on dead turn 3, also be formed with gap 32, like this, can play and control collapsing of dead turn 3 preferably.In addition, in the present embodiment, but cyclic spring pipe 2 adopts the bellows of elastic dilatation, and is as shown in Figure 3.
Like this; When cyclic spring pipe 2 charges into highly pressurised liquid, can make cyclic spring pipe 2 in the past interior contraction of the direction of arrow B as shown in Figure 2 through the pressure of controlling highly pressurised liquid, with the 3 past interior contractions of extrusion friction circle; Thereby hold the turning axle 6 that is braked tightly, thereby realize rotary braking.When the unloading highly pressurised liquid, then cyclic spring pipe 2 shrinks, thereby unclamps turning axle 6.
The present invention carries out rotary braking control owing to adopt such cyclic spring pipe 2 to drive the mode that dead turns 3 collapse, compact structure not only, requirements of installation space is littler, and braking rapidly, efficient is high.The present invention can organize parallel connection more and use, thereby makes the braking moment multiplication.
The present invention both can be used for the turning axle braking of lathe, also can be used for the braking of gearing turning axle.
Like Fig. 4,5, shown in 6.Present embodiment and embodiment's 1 difference is that annular recess 5 is opened on the outer peripheral surface of body 1.Through the expansion of cyclic spring pipe 2, drive dead turn 3 and expand, thereby the revolution sleeve 7 that is set on the dead turn 3 is braked, played good braking effect.When the unloading highly pressurised liquid, just unclamp revolution sleeve 7.All the other mode of executions are identical with embodiment 1.
