Description
Technical field
The utility model is specifically related to a kind of easy-to-dismount axle fixing structure.
Background technique
In traditional mechanical manufacturing field, when axle class mechanical parts require neither to allow that axial float is not allowed again in rotation after mounting, the conventional method adopted on axle, makes step shoulder or the part such as mounting nuts, back-up ring carrys out the axial float of restrictive axes, carrys out rotating in a circumferential direction of restrictive axes with key, pin.There is dismounting difficulty in this kind of axle fixing structure, being not suitable for is needing the occasion of frequent dismounting to use.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of easy-to-dismount axle fixing structure, is not suitable in the problem needing the occasion of frequent dismounting to use to solve existing axle fixing structure dismounting difficulty.
For achieving the above object, technical solution adopted in the utility model is: provide a kind of easy-to-dismount axle fixing structure, comprise rotating shaft, axle locating piece and positioning pressuring plate, shoulder hole is provided with in the middle part of axle locating piece, the mounting hole coaxial with shoulder hole is provided with in the middle part of positioning pressuring plate, rotating shaft is located in shoulder hole and mounting hole, and axle locating piece is evenly equipped with multiple inner bolt hole;
Positioning pressuring plate is evenly equipped with multiple through hole relative with inner bolt hole, the bolt be connected with inner bolt hole is provided with in through hole, positioning pressuring plate is provided with the step I adjacent with axle locating piece and is positioned at the step II of the large end of shoulder hole, is provided with interval between the inner cylindrical surface of the external cylindrical surface of step II and the large end of shoulder hole.
As preferably, the inner bolt hole on axle locating piece has six, and through hole relative with inner bolt hole on positioning pressuring plate has six.
the beneficial effects of the utility model are:
1, the utility model comprises rotating shaft, axle locating piece and positioning pressuring plate, is provided with shoulder hole in the middle part of axle locating piece, is provided with the mounting hole coaxial with shoulder hole in the middle part of positioning pressuring plate, and rotating shaft is located in shoulder hole and mounting hole, and axle locating piece is evenly equipped with multiple inner bolt hole; Positioning pressuring plate is evenly equipped with multiple through hole relative with inner bolt hole, the bolt be connected with inner bolt hole is provided with in through hole, positioning pressuring plate is provided with the step I adjacent with axle locating piece and is positioned at the step II of the large end of shoulder hole, is provided with interval between the inner cylindrical surface of the external cylindrical surface of step II and the large end of shoulder hole.When dismantling this fixed structure, taken off by the bolt of coupling shaft locating piece and positioning pressuring plate, positioning pressuring plate flicks by spring, and positioning pressuring plate takes off by the step I fastening positioning pressuring plate with hand, so just this fixed structure can be taken apart.The simple cost of this fixed structure preparation process is lower, unloading process simple and fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, rotating shaft; 2, axle locating piece; 3, inner bolt hole; 4, step I; 5, through hole; 6, bolt; 7, shoulder hole; 8, step II; 9, positioning pressuring plate; 10, mounting hole; 11, interval.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, the present embodiment provides a kind of easy-to-dismount axle fixing structure, comprise rotating shaft 1, axle locating piece 2 and positioning pressuring plate 9, shoulder hole 7 is provided with in the middle part of axle locating piece 2, the mounting hole 10 coaxial with shoulder hole 7 is provided with in the middle part of positioning pressuring plate 9, rotating shaft 1 is located in shoulder hole 7 and mounting hole 10, axle locating piece 2 is evenly equipped with multiple inner bolt hole 3.
Positioning pressuring plate 9 is evenly equipped with multiple through hole 5 relative with inner bolt hole 3, the bolt 6 be connected with inner bolt hole 3 is provided with in through hole 5, positioning pressuring plate 9 is provided with the step I 4 adjacent with axle locating piece 2 and is positioned at the large step II 8 held of shoulder hole 7, is provided with interval 11 between the inner cylindrical surface that the external cylindrical surface of step II 8 and shoulder hole 7 are held greatly.Inner bolt hole 3 on axle locating piece 2 has six, and through hole 5 relative with inner bolt hole 3 on positioning pressuring plate 9 has six.
In implementation process, when dismantling this fixed structure, taken off by the bolt 6 of coupling shaft locating piece 2 and positioning pressuring plate 9, positioning pressuring plate 9 takes off by the step I 4 fastening positioning pressuring plate 9 with hand, so just this fixed structure can be taken apart.The simple cost of this fixed structure preparation process is lower, unloading process simple and fast.
