Description
Technical field
The invention belongs to automated production field, be mainly used in workpiece and hole gap it is smaller when (unilateral gap is less than
0.05mm), realized by compensation approach automatically by workpiece and the accurate centering of mounting hole.
Background technology
Automated production field is generally required using automation equipment substitution manually, so as to improve the reliability of system, drop
Low production cost and labor intensity.On assembly line, when workpiece is sent into predetermined hole by automated manner, in workpiece and hole
When gap is smaller (unilateral gap is less than 0.05mm)；Compared with manual operation, the flexibility of automatic system is poor；To realize purpose, need
The machining accuracy for all parts that can influence workpiece hole site is improved, this generally requires to change whole part process flow；Together
Shi Caiyong possesses the manipulator (its positioning precision needs the gap being less than between workpiece and mounting hole) of high position precision, and also needs
Will be to the accurate teaching of manipulator.Whole process not only needs to expend substantial amounts of cost and long time, and to teaching personnel
Technical requirements it is high；Cause that when the gap in workpiece and hole is smaller automated production can not be realized.
The content of the invention
For workpiece is sent into predetermined hole using manipulator and automation can not be realized when the gap in workpiece and hole is smaller
The technical problem of production, the present invention provide a kind of two dimensional surface self compensation linkage light-duty intermediate module, can realize that fixture is put down in X-Y
Face internal linkage type compensation movement so that the module can aid in clamping jaw to realize flexible positioning in X-Y plane.When workpiece and hole
When gap is smaller, the machining accuracy for all parts for influenceing workpiece hole site is reduced, used manipulator positioning precision can be with
More than the gap between workpiece and mounting hole, the difficulty of teaching mode reduces.Pass through the light-duty centre of two dimensional surface self compensation linkage
Module, the requirement of relevant cost and teaching personnel can be reduced, save the time of related link.
The present invention technical solution be：Automatically reset principle using compression spring, with reference to linear bearing, realize fixture
Planar link compensation movement, and enabling the module, planar auxiliary clamp realizes flexible positioning.
When clamping workpiece is directed at mounting hole, if folded workpiece has coaxiality error with mounting hole center, two dimension is flat
The self compensation light-duty intermediate module that links in face in the presence of guiding force, moves on one side between workpiece and mounting hole to having contacted,
Realize automatic alignment function.
Put down workpiece and return to non-clamp position, in the presence of spring force and linear bearing, drive fixture to return to original
Position.
The module can planar link, thus can compensate the error of any axiality in plane.
Spring-compressed length is quickly adjusted using spring adjustment axle, to meet the needs of the occasion of different balancing forces.

Embodiment
The light-duty front end installs fixture 15 of intermediate module 14 of two dimensional surface self compensation linkage, the clamping workpiece 16 of fixture 15 make center
During the alignment installation centerline hole 12 of line 13, if coaxiality error be present with installation centerline hole 12 in folded work centre line 13,
Two dimensional surface self compensation links, and (workpiece and mounting hole have down guiding force light-duty intermediate module 14 between workpiece 16 and mounting hole
Angle, guiding force can be produced) in the presence of, to having contacted while mobile, drive X-direction linear bearing 2 and Y-direction linear axis
7 movements, compensation work centre line 13 and the installation coaxiality error of centerline hole 12 are held, is moved by lower interface housing 9, makes workpiece
Center line 13 aligns with installation centerline hole 12 from automatic compensation.
Fixture 15 puts down workpiece and returns to non-clamp position, and two dimensional surface self compensation links light-duty intermediate module 14 in X-direction
Under counterbalance spring 1 and the spring-force driven dual of Y-direction counterbalance spring 5, X-direction linear bearing 2 and the single action of Y-direction linear bearing 7 are promoted
Or linkage causes lower interface housing 9 to return to original position, fixture is driven to reset.
The light-duty intermediate module of two dimensional surface self compensation linkage can compensate plane in X-direction and Y-direction single action or linkage
Interior any direction work centre line 13 and the error of the installation axiality of centerline hole 12.
Axle 4 is adjusted using Y-direction counterbalance spring and X-direction counterbalance spring adjustment axle 10 quickly adjusts X-direction counterbalance spring 1
With the reduction length of Y-direction counterbalance spring 5, the occasions of different balancing forces is met the needs of.
