Description
Technical field
The utility model relates to a kind of processing of hydraulic cylinder part, and in particular to a kind of hydraulic cylinder weldment cylinder bottom
Processing unit (plant).
Background technique
Cylinder bottom is one of component part of hydraulic cylinder, primarily serves the effect connecting with external agency.Weldment cylinder bottom
It is made of cylinder bottom, straight pin, earrings, earrings set, the general processing method of weldment cylinder bottom is first to add to cylinder bottom, earrings
Cylinder bottom and earrings set are welded on earrings by work later, finally process earrings set by machining benchmark of cylinder bottom end face.
In the welding that this processing method middle cylinder bottom and earrings cover using earrings as positioning datum, the processing of earrings set is with cylinder bottom
End face is machining benchmark；Wherein cylinder bottom is easy to produce positioning shakiness and welding deformation relative to earrings, due to weldment cylinder bottom
Size it is elongated, and welding changed with the benchmark finally processed, cause finally using cylinder bottom end face as machining benchmark processing earrings
Earrings set is difficult to reach design requirement relative to the verticality and symmetry of cylinder bottom benchmark A after set.
The qualification rate for processing this cylinder bottom weldment using universal method is too low, and processing cost is higher, therefore is badly in need of providing
A kind of processing unit (plant) is to solve above-mentioned processing problems.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of adding for hydraulic cylinder weldment cylinder bottom
Tooling is set, and to solve in the prior art due to machining benchmark disunity, earrings set caused by welding deformation and positioning are unstable is vertical
Degree and problem of the symmetry relative to cylinder bottom difference improve cylinder bottom weldment processing quality.
To achieve the above object, the utility model uses following technical scheme:
A kind of processing unit (plant) of hydraulic cylinder weldment cylinder bottom, including limited block, pressing plate, stud, nut, cushion block, positioning
Block, bottom plate and jackscrew.The bottom plate is installed on machining center workbench, and bottom plate is equipped with locating piece, and it is fixed to be provided on locating piece
Position slot can place weldment cylinder bottom in locating slot, and locating slot side is equipped with jackscrew, and jackscrew can hold out against weldment cylinder bottom in positioning
In slot；The bottom plate is equipped with bolt, and cushion block, pressing plate are compressed by nut after passing through bolt, can be fixed on weldment cylinder bottom
In locating slot；The bottom plate is equipped with limited block, and limited block is corresponding with one end of locating slot, the weldment being placed in locating slot
Cylinder bottom end is bonded positioning with limited block, and cutter and tooling occur dry when the limit block size will avoid milling earrings set end face
It relates to.
Further, on the locating piece be symmetrical arranged two at locating slot, can simultaneous processing two pieces weldment cylinder bottom, improve
Processing efficiency.
The beneficial effects of the utility model are: its is structurally reasonable, simple, machining benchmark is unified and can eliminate welding deformation
Influence, processing consistency greatly promotes, and processing efficiency is improved, and solves the processing and manufacturing of hydraulic cylinder weldment cylinder bottom
Problem guarantees geometric tolerance, improves process reliability and at low cost, easily fabricated.
