Description
Technical field
The utility model is specifically related to a kind of easy-to-dismount shaft fixing device.
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 shaft fixing device, 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 shaft fixing device, is not suitable in the problem needing the occasion of frequent dismounting to use to solve existing shaft fixing device dismounting difficulty.
For achieving the above object, technical solution adopted in the utility model is: provide a kind of easy-to-dismount shaft fixing device, comprise rotating shaft, axle locating piece and positioning pressuring plate, shoulder hole is provided with in the middle part of axle locating piece, be provided with the mounting hole coaxial with shoulder hole in the middle part of positioning pressuring plate, rotating shaft is located in shoulder hole and mounting hole;
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, be provided with the bolt be connected with inner bolt hole 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 inside of shoulder hole; Be provided with the circular groove coaxial with shoulder hole in shoulder hole, in circular groove, be provided with the spring compressed by step II end face of positioning pressuring plate.
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;
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, be provided with the bolt be connected with inner bolt hole 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 inside of shoulder hole; Be provided with the circular groove coaxial with shoulder hole in shoulder hole, in circular groove, be provided with the spring compressed by step II end face of positioning pressuring plate.When dismantling this fixing device, taken off by the bolt of coupling shaft locating piece and positioning pressuring plate, positioning pressuring plate flicks by spring, is finally taken off by positioning pressuring plate and this fixed structure can be taken apart.The simple cost of this fixing device preparation process is lower, unloading process simple and fast.
