Description

Self-positioning floating bearing with multiple degrees of freedom

Technical Field

The utility model relates to a work piece centre gripping degree of freedom technical field specifically is the unsteady supporting of self-align who has a plurality of degrees of freedom.

Background

After the workpiece is clamped, the degree of freedom of the workpiece in the workpiece is limited, so that the workpiece is possibly limited during processing, the workpiece needs to be disassembled and clamped again to continue processing, and thus, the process is complicated and the operation is complex;

in view of the foregoing, it is desirable to design a self-locating floating bearing with multiple degrees of freedom to increase the degree of applicability.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art, the utility model provides a from unsteady supporting of locating with a plurality of degrees of freedom has solved the problem mentioned in the background art.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the self-positioning floating support with multiple degrees of freedom comprises a first part and a second part, wherein floating supports are arranged outside the first part and the second part, and clamping assemblies are arranged in the floating supports, so that multiple degrees of freedom are realized on workpieces at the first part and the second part.

Further, the floating support comprises two symmetrical supports, and the two supports are combined through external force to be wholly supported and then clamp the workpiece.

Further, two supports all are square setting.

Further, the clamping assembly includes:

the rolling grooves are formed in the supports, and two rolling grooves which are arranged up and down are formed in one support;

the ball bodies are arranged in the rolling grooves in a rolling mode, and the workpieces on the first workpiece and the second workpiece are located in the middle of the four ball bodies.

Compared with the prior art, the utility model following beneficial effect possesses: the workpieces at the first position and the second position can do linear motion and rotary motion, the workpieces at the second position swing around the first center, and under the action of an external force F, the four spheres clamp the workpieces, so that the workpieces can have multiple degrees of freedom.

Drawings

FIG. 1 is a front view of the floating support of the present invention;

fig. 2 is a side view of the floating bearing of the present invention.

In the figure: 1-one piece I, 2-two piece II, 3-bracket, 4-rolling groove and 5-sphere.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the self-positioning floating support with multiple degrees of freedom comprises a first part 1 and a second part 2, the floating support is arranged outside the first part 1 and the second part 2, and a clamping assembly is arranged in the floating support, so that multiple degrees of freedom are realized on a workpiece on the first part 1 and the second part 2.

The floating support comprises two supports 3 which are symmetrical to each other, the two supports 3 are all arranged in a square mode, the two supports 3 are combined through the action of external force to be wholly supported and then clamp a workpiece, and the workpiece at the first position 1 and the second position 2 can move linearly and move in a rotary mode.

The clamping assembly includes:

the rolling grooves 4 are formed in the brackets 3, and two rolling grooves 4 which are vertically arranged are formed in one bracket 3;

the ball body 5 and the ball body 5 are arranged in the rolling groove 4 in a rolling mode, the workpiece on the first ball body 1 and the second ball body 2 is located in the middle of the four ball bodies 5, and under the action of an external force F, the four ball bodies 5 clamp the workpiece, so that the workpiece can have multiple degrees of freedom.

During operation, the workpieces at the positions of the first part 1 and the second part 2 can do linear motion and rotary motion, the workpieces at the positions of the second part 2 swing around the center of the first part 1, and under the action of an external force F, the four spheres 5 clamp the workpieces, so that the workpieces can have multiple degrees of freedom.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
