CN102049785A - Ball connection type anti-vibration synarthrosis - Google Patents

Abstract

The invention relates to a ball connection type anti-vibration synarthrosis belonging to the field of robots, automatic production lines and mechanical manufacture, and a method for fixedly connecting two objects (or two parts of one object) through a spherical part and enabling a connection area to have a capability of resorbing various types of force being unnecessary to transfer in a body. Fixity exists between the objects which are connected through the method, when the connected objects receive external force, the received force is transferred in the connected objects, a considerable amount of the force is resorbed when passing through the connection area, and the resorbable amount can be regulated.

Description

Ball connects formula vibrationproof synarthrodia

Field: robot, automatic production line and machine-building

Background: as the term suggests the joint is exactly crucial the connection.Joint of animal is the place that head of phalanx connects, and is divided into synarthrodia, amphiarthrosis and turning joint.Because bone surface all has tough and tensile periosteum, so all joint of animal all have certain anti-vibration functions, especially turning joint also has bone liquid, and anti-vibration functions is better.The activity of artificial mechanisms such as robot wants to reach or surmount the degree of flexibility of animal limb activity, and each crucial connecting portion is the joint just.Must possess certain anti-vibration functions, with the unnecessary transmission of molten various power in integral body that disappear.Mechanical joint also can be divided into synarthrodia and diarthrosis.

Purpose: make spherical motionless (machinery) joint

Scheme:

One, joint

As shown in drawings, the hard material that the material selection mechanical strength is good, the pawl number can according to circumstances be made by oneself, pawl is long to be needed above the centre of sphere (can embrace the ball that external diameter equals the joint internal diameter), two joints are buckled into a hollow spheres, fasten latter two joint and divide between the pawl certain clearance should be arranged, and inwall has accepts the asperities that the ball tire expands, the pawl base is following to be the bonding pad, and the object a bit any or that face can be connected with need of bonding pad is connected as a single entity.Must there be one to establish the charging connector eye in two joints that fasten.

Two, ball tire

The ball tire accompanies meridianal spherical rubber inflatable ball exactly, and external diameter equals the internal diameter that two joints fasten the georama that forms, and anti-automatically ease gas charging connector is arranged.

Three, combination (referring to accompanying drawing 2)

Need to connect object and fix with the joint bonding pad respectively, ball tire charging connector to going into the charging connector eye of joint, is fastened another joint inflation, make the pawl of two joints all embrace firm ball tire.

Four, description of drawings

Accompanying drawing 1 is the joint schematic diagram, and accompanying drawing 2 is a ball chain type vibrationproof synarthrodia schematic appearance.

Effect: the ball tire tightly is connected as a single entity two joints, which point of two joint whichever joints that are connected as a single entity is subjected to power, this power must be passed through the ball tire to another joint transmission, and the power in out-of-date transmission has the molten and amount molten power that can disappear of disappearing of a great deal of here and can regulate by the size of ball air pressure.

Claims (3)

1. Fixedly connected two objects (or two parts of an object) and the junction is possessed disappear molten various in connector the method for the power of unnecessary transmission, its concrete feature is, needing to connect object fixedlys connected with the bonding pad of two joints respectively, two joints are buckled into hollow ball shell, Place tire in the spherical shell that is buckled into, the inflation of ball tire firmly fuses two joints.
2. 2. parts shown in the good Figure of description of making according to the hard material that it is good that the joint in the claim 1 is mechanical strength 1, two joints can be buckled into a georama, the pawl number can be made by oneself, and no claw is the bonding pad, and inner nosepiece wall has can accept the asperities that the ball tire expands.
3. 3. be the inflated rubber ball that accompanies meridian (preventing excessive expansion) according to the ball tire in the claim 1, external diameter equals the joint internal diameter.
