Description
Technical field
The utility model relates to a kind of excavator swing arm hinge hole processing unit (plant), belongs to the excavator technical field.
Background technology
Make the field at excavator and other engineering machinery, swing arm is the equipment of excavator and other engineering machinery, so the precision of swing arm processing directly influences the serviceability and the service life of complete machine.Swing arm is a structural member that is formed by a plurality of assembly weldings, as shown in Figure 1, is the boom structure front view, and Fig. 2 is its vertical view.Described swing arm comprises arc body 25, and arc body 25 middle parts are respectively equipped with the 4th hinge hole 24 and second hinge hole 22, and two arm ends of arc body 25 are respectively equipped with first hinge hole 21 and the 3rd hinge hole 23.When work, these four fulcrums that hinge hole is connecting moves.Therefore swing arm must a clamping processes at one time and guarantees the parallel to each other and left-right symmetry of four hinge holes.Otherwise machine performance will be had a greatly reduced quality.
In those early years, the mechanization degree of China also is not under the very high situation, wants multiple clamping for the large scale structural member of processing as the swing arm, and multiple devices just can be finished; And the non-cutting time of adjusting is long especially.Along with the lifting of Chinese mechanization degree, introduced the large-sized numerical control machining center, can high accuracy, the frock of finishing a clamping time processing expeditiously just become to capture difficult point; Moreover the swing arm surface structure form of the excavator of various tonnages is similar, and can a cover frock realize that the mach versatility of several adjacent tonnage swing arms is most important.Just can save a large amount of adjustment time raising working (machining) efficiencies in case well captured above difficult point, greatly reduce manufacturing cost simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of quick location, realizes disposable clamping processing and the high excavator swing arm hinge hole processing unit (plant) of versatility.
In order to achieve the above object, the technical solution of the utility model provides a kind of excavator swing arm hinge hole processing unit (plant), it is characterized in that, comprise the prelocalization seat, interfix seat and back positioning seat, the prelocalization seat links to each other by first limited block with the interfix seat, the interfix seat links to each other by second limited block with the back positioning seat, prelocalization seat rear side and positioning seat front side, back all are provided with the side positioner, prelocalization seat front side and back positioning seat rear side all are provided with the location and adjust seat, the location is adjusted the seat top and is provided with pressing plate, adjustment seat middle part, location is provided with two location and adjusts double-screw bolt, both sides all were provided with first alignment pin before and after seat was adjusted in the location, side positioner and location are adjusted to be provided with between the seat to locate and are compressed double-screw bolt, interfix seat base plate middle part is provided with the location and compresses double-screw bolt, and the upper left side of interfix seat two side is provided with second alignment pin, the upper right side is provided with the location and adjusts double-screw bolt, the middle part is provided with the side positioner, the lower right side is provided with the 3rd alignment pin.
Further, described location compresses double-screw bolt and is provided with bucker.
The utility model adopts segmented positioning and clamping mode, solves common processing vibration problems; Work in-process is in the heart by workbench one piece clamping; If machining center is changed other workpiece, just can be placed apart it, significantly reduce parking space; Design side positioner has shortened the adjustment time, can realize automation faster in process, is convenient to adjust the swing arm left-right symmetry; Designed bucker, solved the location compress double-screw bolt of long duration the dead problem of will becoming rusty.
