Description
Technical field
The present invention relates to a kind of pin shafts, more specifically to a kind of fixing structure for pin shaft.
Background technique
Pin shaft is usually used in the connection of two hinge members, and since stress is huge in engineering machinery, pin shaft size is usual
It is larger.In order to avoid pin shaft rotates in pin shaft hole, usually pin shaft and a wherein hinge member are fixed.Existing pin shaft is fixed
Method is that otic placode is arranged in end part of pin shaft, and otic placode is fixedly connected with pin body, such as is mutually welded, and it is logical that one is arranged on otic placode
Hole, fixing bolt pass through the threaded hole on through-hole and hinge member and cooperate, and otic placode is fixed in realization, so that pin shaft be fixed.?
In this fixing structure for pin shaft, otic placode will mutually be welded with pin body, and process is relatively cumbersome, at high cost.
Summary of the invention
The technical problem to be solved by the present invention is to be directed in existing fixing structure for pin shaft to need with pin shaft mutually to weld otic placode
Caused by relatively cumbersome, the at high cost problem of process, and provide a kind of structure it is simple, without the fixing structure for pin shaft of welding.
The present invention is to realize that the technical solution of its purpose is such that provide a kind of fixing structure for pin shaft, including pedestal, pin
Axis is provided with pin shaft hole on the pedestal, and the pin shaft is inserted into the pin shaft hole, it is characterised in that further includes passing through bolt
Fixed plate on the substrate is fixedly mounted, the fixed plate has at least one straight flange, the end part of pin shaft cylindrical side
On be provided at least one groove, the straight flange of the fixed plate is located in the groove of the pin shaft and is bonded with groove floor.?
In the present invention, using the cooperation of fixed plate and pin shaft groove, prevent pin shaft is from moving axially, at the same the straight flange in fixed plate with
The bottom surface of groove can prevent pin shaft from axially rotating and moving radially, to achieve the purpose that pin shaft is fixed.
Further, also have in above-mentioned fixing structure for pin shaft, in the fixed plate and constitute L-shaped the with the straight flange
Two sides, second side and the end part of pin shaft cylindrical side connect.Further, second side and the pin shaft it
Between contact point to the maximum normal distance between groove floor be greater than pin shaft axle center to groove floor distance.Second side can be with
It is straight flange, is also possible to the arc-shaped side being bonded with end part of pin shaft cylindrical side.Further, the fixed plate only passes through a spiral shell
Bolt is fixedly connected with the pedestal, and the bolt is arranged in fixed plate and using the A point as the center of circle, respectively with pin shaft axle center with
The extended line of A point line and by the ray of A point and B point be boundary fan-shaped region in, the A point is the in the fixed plate
There is the contact point of maximum normal distance with groove floor, the B point is groove in the point that two sides are contacted with pin shaft cylindrical side
With A point apart from nearest point on bottom surface.
It further, can be also to have and the straight flange other end in the fixed plate in above-mentioned fixing structure for pin shaft
The third side of connection, described second in, third and the straight flange constitutes trapezoidal recess, and the pin shaft is located at the trapezoidal recess
It is interior, described second while and connected with the pin shaft cylindrical side when third.Equally, third side be also possible to straight flange or with
The arc-shaped side of end part of pin shaft cylindrical side fitting.At this time can fixed plate only pass through a bolt and be fixedly connected with the pedestal, and
And achieve the purpose that anti-rotation.
Compared with prior art, the present invention inventive pin axle fixing structure is not necessarily to welding, but in the cylindrical side of pin shaft
On open up groove, cooperate with the straight flange for being fixedly mounted on pedestal upper mounted plate and reaching prevents that pin shaft is axial, moves radially and week
To the purpose of rotation, groove is opened up relative to welding, simple process and low cost.
Detailed description of the invention
Fig. 1 is the exploded view of inventive pin axle fixing structure.
Fig. 2 is the installation diagram of inventive pin axle fixing structure.
Fig. 3 is the position schematic diagram of bolt in inventive pin axle fixing structure.
Parts title and serial number in figure:
Pin shaft 1, groove 11, fixed plate 2, through-hole 21, gasket 3, bolt 4, hinged rotatable parts 5, hinged seat 6, pin shaft hole
