The utility model announce it is a kind of can convenient disassembly hydraulic cylinder ears template cylinder bottom steel bushing mounting structure, belong to hydraulic cylinder technical field.Including cylinder bottom, cylinder bottom is fixed with a pair of of otic placode, and the two otic placode centers are machined with opposite through-hole；The otic placode end face outside is provided with deep gouge；Steel bushing is installed, steel bushing and otic placode via clearance cooperate in the through-hole of two otic placodes；Described steel bushing one end is fixed with fixed plate, and fixed plate is fixed in the deep gouge on the outside of otic placode.The aperture of steel bushing and the through-hole at two otic placode centers is clearance fit in the utility model, and when in use, steel bushing can be easily passed through in otic placode through-hole；Then, it in the deep gouge that the fixed plate of steel bushing one end is installed to side otic placode, and is quickly fixed with fixing bolt.Compared with prior art, the utility model improves steel bushing press fitting, after-sales service efficiency, and stable structure is reliable, versatile.
Description
Technical field
The utility model relates to hydraulic cylinder technical field, it is specifically a kind of can convenient disassembly hydraulic cylinder ears template cylinder bottom
Steel bushing mounting structure.
Background technique
Hydraulic cylinder ears template cylinder bottom or earrings upper pin hole are often equipped with steel bushing, and steel bushing inner surface is connect with pin shaft.
It is to avoid directly wearing cylinder bottoms of hydraulic cylinders or earrings itself when hydraulic cylinder working in reciprocating mode using purpose, is only worn in steel bushing
The service life of cylinder bottoms of hydraulic cylinders or earrings itself is improved on surface.Conventional mounting fixed form are as follows: on steel bushing outer diameter and cylinder bottom or earrings
Hole be transition fit, cause:
1., it is tight fit, not easy to install, need special pressure machine to be pressed, low efficiency；
2., press machine press fitting steel bushing when, cylinder sleeve is often deformed because the otic placode sky with cylinder bottom quotient is transition fit, into
And cause often can not normally be pressed into second lug plate holes after passing through first otic placode；
3., when steel bushing is worn, be not easy convenient dismounting maintenance.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of hydraulic cylinder ears template cylinder bottom steel bushing of convenient disassembly
Mounting structure improves maintenance efficiency with the convenient assembly of detachable structure implementation type hydraulic cylinder.
The utility model is achieved through the following technical solutions: a kind of hydraulic cylinder ears template cylinder bottom steel bushing peace of convenient disassembly
Assembling structure, including cylinder bottom, cylinder bottom are fixed with a pair of of otic placode, and the two otic placode centers are machined with opposite through-hole；Outside the otic placode
Side end face is provided with deep gouge；Steel bushing is installed, steel bushing and otic placode via clearance cooperate in the through-hole of two otic placodes；The steel bushing
One end is fixed with fixed plate, and fixed plate is fixed in the deep gouge on the outside of otic placode.
Preferred: the steel bushing outside middle portion is provided with lubricating cup mounting hole, is equipped with lubricating cup in lubricating cup mounting hole.
Preferred: two otic placodes are centrosymmetrically arranged along cylinder bottom；It sinks described in the outer Flank machining of the otic placode of side
Slot, deep gouge inner end are connected to otic placode through-hole；The deep gouge bottom is provided with threaded hole.
Preferred: the fixed plate is vertically welded in steel bushing end sides, and the width dimensions of fixed plate are slightly less than deep gouge
Width dimensions, fixed plate middle part are provided with the unthreaded hole opposite with deep gouge threaded hole；Fixing bolt passes through unthreaded hole, is mounted on deep gouge screw thread
Kong Zhong.
The aperture of steel bushing and the through-hole at two otic placode centers is clearance fit in the utility model, and when in use, steel bushing can
To be easily passed through in otic placode through-hole；Then, it in the deep gouge that the fixed plate of steel bushing one end is installed to side otic placode, is used in combination
Fixing bolt is quickly fixed.
Compared with prior art, the utility model has the beneficial effects that improving steel bushing press fitting, after-sales service efficiency, knot
Structure is reliable and stable, versatile.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is steel bushing main view；
Fig. 3 is convex middle right view；
In figure: 1, cylinder bottom；2, otic placode；2-1, deep gouge；3, fixed plate；4, lubricating cup；5, fixing bolt；6, steel bushing.
Specific embodiment
It is a specific embodiment of the utility model below, the utility model is described further now in conjunction with attached drawing.
In conjunction with shown in Fig. 1 to Fig. 3, a kind of hydraulic cylinder ears template cylinder bottom steel bushing mounting structure of convenient disassembly, cylinder bottom 1 is consolidated
Surely there is a pair of of otic placode 2, two otic placodes 2 are centrosymmetrically arranged along cylinder bottom 1.Two otic placodes, 2 center is machined with opposite through-hole, wherein side
The outer Flank machining of otic placode 2 go out deep gouge 2-1, the inner end deep gouge 2-1 is connected to 2 through-hole of otic placode；The bottom deep gouge 2-1 is provided with threaded hole,
The specification of threaded hole is consistent with the screw thread specification of fixing bolt 5.
Steel bushing 6 is mounted in the through-hole of two otic placodes 2, and steel bushing 6 and 2 via clearance of otic placode cooperate, 6 length of steel bushing and cylinder bottom
The length of the lateral surface distance of two otic placodes 2 is consistent.6 outside middle portion of steel bushing is opened there are two centrosymmetric lubricating cup mounting hole,
Lubricating cup 4 is installed in lubricating cup mounting hole.
Fixed plate 3 is vertically welded in 6 end sides of steel bushing, and the width dimensions of fixed plate 3 are slightly less than the broad-ruler of deep gouge 2-1
It is very little, the unthreaded hole opposite with deep gouge 2-1 threaded hole is provided in the middle part of fixed plate 3, unthreaded hole diameter is slightly larger than the screw thread specification of fixing bolt 5
Size.Fixing bolt 5 passes through unthreaded hole, is mounted in deep gouge 2-1 threaded hole, fixed plate 3 is pressed in 2 deep gouge 2-1 of otic placode.
In use, steel bushing is through in two otic placode through-holes；Then, the fixed plate of steel bushing one end is installed into side otic placode
In deep gouge, and quickly fixed with fixing bolt.Above-described embodiment can be seen that the utility model improve steel bushing press fitting, after sale
Maintenance efficiency, stable structure are reliable, versatile.
