Mainly there is following shortcoming in existing joint arm: one is that joint arm adopts simple joint to rotate mostly, lack multi-joint, in any direction can linear extension and can the spine joint arm of 360 degree of rotoflectors, make joint arm both be difficult to keep gravity balance, specific movement locus can not be realized; Two is that monarthric joint arm only has one degree of freedom, greatly reduces the scope of application of joint arm.
Summary of the invention
Mainly there is following shortcoming for joint arm existing in prior art in the utility model: one is that joint arm adopts simple joint to rotate mostly, lack multi-joint, in any direction can linear extension and can the spine joint arm of 360 degree of rotoflectors, make joint arm both be difficult to keep gravity balance, specific movement locus can not be realized; Two is that monarthric joint arm only has one degree of freedom, greatly reduce the scope of application of joint arm, provide a kind of have five frees degree, in any direction can linear extension and can the extending spine joint arm of three fulcrums, 360 degree of rotoflectors of 360 degree of rotoflectors.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The extending spine joint arm of a kind of three fulcrums, 360 degree of rotoflectors, comprises pass segmented column, and close segmented column and comprise power transmission shaft, joint arm body, universal joint, joint arm body is located on power transmission shaft, and universal joint one end is fastened between power transmission shaft and joint arm body.
As preferably, two ends, power transmission shaft left and right are all arranged with universal joint.
As preferably, be flexibly connected by universal joint between adjacent two pass segmented columns.
As preferably, between adjacent two pass segmented columns, comprise portable connection and rotary connection by the flexible connection of universal joint.Close the moving left and right of segmented column, move forward and backward, move up and down and be portable connection, the rotation and the bending motion that close segmented column are rotary connection.
As preferably, the anglec of rotation of the pass segmented column of rotary connection is 0 ~ 360 degree.
As preferably, universal joint is screw thread universal joint.
As preferably, power transmission shaft is three, and the axial connecting line of three power transmission shafts forms three fulcrums of equilateral triangle.
As preferably, outside joint arm body, be arranged with housing.
Pass of the present utility model segmented column is two or more, and two or more joint post forms multi-joint column construction.The spine joint arm of multi-joint column construction has five frees degree, five frees degree are respectively: X-direction move left and right as one degree of freedom, Y direction move forward and backward as one degree of freedom, Z-direction move up and down as one degree of freedom, XYZ space rotates to be one degree of freedom, XYZ space is bent into one degree of freedom.
The utility model is owing to have employed above technical scheme, there is significant technique effect: the spine joint arm adopting five frees degree, by the joint arm main body of threaded universal joint arranges three fulcrums, make joint arm in any direction can linear extension and can 360 degree of rotoflectors, substantially increase the gravity balance ability of joint arm, and there is self-lock ability, achieve the specific movement locus of joint arm and 360 degree of omnibearing scopes of application, this joint arm structure is comparatively simple, installs and operation facility.
