Accompanying drawing explanation

Fig. 1 be adaptive damping of the present invention joint structural representation.

Fig. 2 is the operation schematic diagram that the present invention uses aborning.

In figure: 1-ball and socket joint, 2-fossa glenoid, 3-controlling device, 4-joint handle, 5-joint handle, 6-ball and socket joint.11-pull bar inner sleeve, 12-rod outer sleeve, 13-adjusting bolt, 14-workpiece a, 15-workpiece b, 16-clip, 17-clip, 18-controlling device, 19-controlling device, 20-controlling device.

Embodiment

As Fig. 1, ball and socket joint 1 is a spheroid with certain radius, after connect joint handle 5; Fossa glenoid 2 is the spherical shells that inside radius is slightly less than ball and socket joint 1, prunes 1/3 above, from centre, is divided into two; Also can be two members with hemispherical Shell equally manufacturing.On joint handle 4 tops, fossa glenoid 2 roots arrange adjusting mounting hole, proceed to bolt and the convenient wing nut using that regulates, and form controlling device 3.The other end of fossa glenoid 2 can be also ball and socket joint 6.

Unclamp nut, ball and socket joint is inserted to fossa glenoid.If need it in low resistance working state, adjusting nut is pine just, and joint is in sliding mode more freely; If need it in middle damping state, adjusting nut is just tight, joint in can fix and adjustable can twisted posture; If need it in high damping working state, the lock state under working load active force namely, fastening nut more just, until this working load active force can not make joint be twisted.

Nut in this controlling device 3 can be also wedge block, by end, by pull bar or the pull bar that installed ratchet additional, realize to be regulated, and adjustings can be realized by adjusting nut in this kind of adaptive damping joint, also can be by stirring ratchet realization adjusting.This adjusting also can be fixed by fossa glenoid, and ball and socket joint is expanded, and reaches the object that changes damping and locking.The head in this kind of joint and the surface of nest, for meeting different operating load, the damping realizing within the specific limits regulates, it can be the smooth surface of low resistance, also can be the roughened surface of high damping, or add lubriation material or damping material, specifically by service condition, be determined.

Various material manufactures that can moulding can be used at present in this adaptive damping joint, as plastics, and timber, bamboo, various metals and alloy etc.Can make the joint of various sizes, end also can have various connections, as flange plate, and clip, hook, various machinery tools etc.The simplest, for example, can found on the ground a bar, fossa glenoid is fixed on the ground with flange plate, vertical rod can have numerous position.

If vertical rod can be elongated again, and we already widely used TV telescopic antenna seem very elephant, different is, here our seat is adaptive damping joint, can fix, and this is also the polar coordinate system in mathematics, change angle and length, can determine the position of any point, space.Such characteristic facilitates us to use a plurality of adaptive dampings joint to connect and compose the helper of similar mankind's arm.

As Fig. 2, in a work cell, because simple in structure, we use several adaptive dampings joint to form the mechanical arm of two arms of similar people.The 11st, the inner sleeve of drawbar structure, the 12nd, overcoat, 13 represent adjusting bolt, 14,15 represent two workpiece.16,17 clamp devices that represent to be used for clamping work pieces, can select according to the workpiece that will clamp, and generally select the adjustable anchorage clip of spiral of similar bench vice.3,18,19,20 expressions is all damping adjustment device, generally screw bolt and nut, consists of.Seeming, is exactly realize bench vice rotatable, removable here, is almost can clamp at any angle.

Damping adjusting controlling device 3 and 20 bolts, these two arms just can be in room each half place wave, regulating tie bar structure adjusting bolt, these two arms can also be waved arbitrarily arm in half many place.Like this, allow their coordinate, two workpiece according to rigging position to together, or double-screw bolt installs, or welding, rivet ... can easily carry out, not have other people to help, a Ms also can complete, and fit dimension also can be fine.Because, these two mechanical arms, fastening nut, allows them not move, and how long their acts can not tire out.

Have such mechanical arm, no matter be what grotesque workpiece, we do not need separately to do fixture, they can be gathered and are combined together.Workpiece is many, and two mechanical arms are inadequate, can also add.There is so mechanical helper, cold, that scald, poisonous, harmful, they are not all minded.Because they are machinery, there is no position problem, elbow can turn inwards, also can outwards turn, and we can be arbitrarily adjusted to the comparatively comfortable position of human body while working them, up and down, process which position and all facilitate.And their strength can be afraid of toil again than the National People's Congress, certainly workpiece is too heavy, and people can not move specified position to, also needs to use crane.

Particularly sometimes, for example, main equipment is as vehicle, boats and ships, mine, the installations such as bridge, processing work, have various angles, for example sideling punching, polishing, the mechanical helper who consists of adaptive damping joint like this, can regulate by quick random, and recycling pull bar regulates push-and-pull, process equipment is fixed on to front end, can realizes light and high progress, high-precision operation.

Human body mainly consists of bone, muscle, tendon, blood vessel, nerve etc., and people has thought an action, and moulding is sent signal by nervous system, and muscle produces and stretches, shrinks, and bone is subjected to displacement at joint, and people has just completed an action, moulding.The maintenance of human action, is also to provide signal by nervous system, by muscle deformation, has been kept.Robot, many is by motor rotation, gear rotates execution, moulding.And the present invention, even if only use adaptive damping joint, makes skeleton, by each joint of artificial adjustment, can complete equally the compound action of various human bodies, and, the action that normal person can do, pendulum moulding more than.Certainly, same principle, can make various animals with this adaptive damping joint, allows them complete exercises, moulding.This has for example also facilitated teaching, scientific research, toy, animation, animation making and movies-making put scape.

In a word, the mechanical helper of the mechanical component that this manual tune consists of adaptive damping joint very easily and the similar people's who combines arm, for for example adjusting of desk lamp, display device, open antenna, machining, make toy, animation, daily life all brings many convenience at home.
