The utility model relates to fixing structure for pin shaft, to solve the problems, such as to need process caused by mutually welding otic placode with pin shaft relatively cumbersome, at high cost in existing fixing structure for pin shaft；A kind of fixing structure for pin shaft is provided, including pedestal, the fixed plate for being bolted on pedestal, pin shaft, pin shaft hole is set on pedestal, pin shaft is inserted into pin shaft hole, limited block is welded on pedestal, it is provided with the groove that bottom is plane on end part of pin shaft cylindrical side, there is in fixed plate the straight flange being bonded in the groove for being embedded into pin shaft with groove floor, the side opposite with straight flange is the limit contact edge contacted with the fitting of the side of limited block in fixed plate.The utility model fixed plate is fixed by bolt and limit plate, pin shaft carries out axial, circumferential and radial fixation by fixed plate, achieve the purpose that prevent pin shaft axial direction, move radially and circumferentially rotate, pin shaft opens up groove and welded limiting block forms otic placode relative to processing and welds in end part of pin shaft on the base, its simple process and low cost.
Description
Technical field
The utility model 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.
Utility model content
The technical problems to be solved in the utility model is to be directed in existing fixing structure for pin shaft to need otic placode and pin shaft phase
Relatively cumbersome, the at high cost problem of process caused by welding, and provide a kind of structure it is simple, without the pin shaft fixed knot of welding
Structure.
The utility model is to realize that the technical solution of its purpose is such that provide a kind of fixing structure for pin shaft, including base
Seat, pin shaft are 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 leading to
The fixed plate that bolt and the pedestal are fixed is crossed, limited block is welded on the pedestal, is set on the end part of pin shaft cylindrical side
Be equipped with the groove that bottom is plane, have in the fixed plate be bonded in the groove for being embedded into the pin shaft with groove floor it is straight
Side, the side opposite with the straight flange is to be bonded the limit contact edge contacted with the side of the limited block in the fixed plate.
Further, in above-mentioned fixing structure for pin shaft, the face that the limited block is contacted with the fixed plate is plane.It is described
The side contacted in fixed plate with the limited block is limit straight flange, the limit straight flange and straight flange arrangement at an acute angle；It is described
Hole in fixed plate for passing through for the bolt is long hole, and the length direction of the long hole is parallel with the limit straight flange.
Compared with prior art, the utility model fixed plate is fixed the utility model by bolt and limit plate, pin
Axis carries out axial, circumferential and radial fixation by fixed plate, reaches the mesh for preventing that pin shaft is axial, moves radially and circumferentially rotates
, pin shaft opens up groove and welded limiting block forms otic placode relative to processing and welds in end part of pin shaft, technique on the base
Simply, at low cost.
Detailed description of the invention
Fig. 1 is the installation diagram of the utility model fixing structure for pin shaft.
Fig. 2 is the exploded view of the utility model fixing structure for pin shaft.
Parts title and serial number in figure:
Pin shaft 1, groove 11, fixed plate 2, through-hole 21, gasket 3, bolt 4, hinged seat 5, pin shaft hole 51, threaded hole 52, limit
Position block 6, hinged rotatable parts 7.
Specific embodiment
Illustrate specific embodiment with reference to the accompanying drawing.
As shown in Fig. 1 Fig. 2, in the present embodiment, fixing structure for pin shaft includes hinged seat 5, the pin shaft 1, bolt as pedestal
4, fixed plate 2 and gasket 3, hinged seat 5 is hinged by pin shaft 1 and the end of hinged rotatable parts 7, is provided with pin on hinged seat 5
Axis hole 51 and threaded hole 52, pin shaft 1 are inserted into pin shaft hole 51, and through-hole 21 is provided in fixed plate 2, and bolt 4, which passes through, to be fixed
Through-hole 21 on plate 2 is threadedly engaged with threaded hole 52 to be connect, and fixed plate 2 is fixedly mounted on hinged seat 5 by realization, in bolt 4
Upper socket gasket 3 realizes that bolt 4 is locking.
As shown in Fig. 2, being provided with a groove 11 on the end cylindrical side of pin shaft 1, welded on hinged seat 5 limited
Position block, side of the limited block 6 towards pin shaft is plane.Fixed plate is wedge shape, has and is embedded on end part of pin shaft cylindrical side
Straight flange 22 in groove also has the limit contact edge 23 closed towards bearing pin side face paste with limited block, limit in fixed plate
Contact edge is at an acute angle with straight flange, so that fixed plate is wedge shaped.Through-hole 21 in fixed plate is long hole, length direction and limit
Contact edge is parallel.
As shown in Figure 1, in the present invention, after pin shaft is inserted into pin shaft hole, fixed plate is then close to hinged seat
It is inserted into the groove 11 of end part of pin shaft cylindrical side, fixed plate is being fixed on by hinged seat 5 by bolt and gasket.In this reality
In novel, fixed plate is wedge shaped, therefore fixed plate can be easily inserted into the gap between groove 11 and limited block,
And it wedging can fix well.
