Description

A kind of five-axis robot fixture

Technical field

The utility model belongs to machine tools field, and in particular to a kind of five-axis robot fixture.

Background technology

Equipment manufacture is the foundation stone of National Industrial, is indispensable industry.As country develops rapidly, for product Processing request more and more higher, such as five axle parts processing when required precision more and more higher, especially in five axles When the surface of the multiple different directions of part is required for being machined out, conventional processing mode is to consolidate five axle parts at present Fixed cutter first processes a face on the table, and face repositioning then will be being changed under detaching products, other faces are being processed, This kind of processing mode needs multiple bearing, causes accumulated tolerance to beat.Also using wedging and the composite structure compressed to five axles zero Part, which is clamped, to be processed, but this structure has enjoyable risk, and very big frictional force is produced during nipping is tight, can The deformation or damage of product can be caused, so processing precision of products is low, and waste machining period.

The content of the invention

The utility model purpose provide a kind of five-axis robot fixture, the deficiency solved the above problems, overcome wedging and The defect that composite structure produces very big frictional force in clamping is compressed, not only effectively prevents from not reducing on the premise of crushing product Clamping force.

The utility model is achieved in the following ways a kind of five-axis robot fixture, is mainly compressed by fixed plate and two Mechanism and an afterbody hold-down mechanism composition, described fixed plate is semicircle, two hold-down mechanisms and afterbody compacting machine configuration Into a rounded projections arranged and the upper table surface of fixed plate is arranged on, why claims rounded projections arranged because the structure of triangle is most firm Lean on, the compacting by hold-down mechanism to front end, afterbody hold-down mechanism play compress and positioning left and right, three cylinders respectively with pressure Tight mechanism and the connection of afterbody hold-down mechanism, three cylinders are bolted on the following table of fixed plate respectively.Described compression Mechanism includes being installed with active connector on pressure head, jam-packed roller, locating piece, the piston of cylinder, and active connector upper end is fixed Jam-packed roller bearing.Jam-packed roller bearing is provided with jam-packed roller, and described jam-packed roller is arranged on jam-packed roller bearing by jam-packed roller pin, Using rolling friction, reducing friction resistance to greatest extent, pressure head is located above jam-packed roller and is fixed on jam-packed roller bearing, with The locating piece that pressure head is engaged is bolted in fixed plate.Described afterbody hold-down mechanism mainly include pressing plate, depression bar, Lever support, support block.Described pressing plate is fixed on the upper end of depression bar, and the lower end of depression bar is bolted in support block, Support block is fixedly connected with the piston of cylinder, and depression bar is arranged on lever support by pin, and lever support is fixed on fixed plate On, lever support not only plays a part of supporting depression bar, also acts as the effect to processing workpiece positioning.Described pressing plate and depression bar For integral type structure.

The beneficial effects of the utility model are that structure design is simple and practical, and small volume clamping force is relatively large, so staying Space to process tool is bigger, and the cutter beaten can be used to be processed, and improves the efficiency and precision of processing, and carries Convenient, the structure uses rolling friction, reduces frictional force to greatest extent, can realize that multiaspect is multi-faceted and be processed.
