Description
Technical field
The invention belongs to mechanical equipment technical field, and in particular to a kind of manual quick lock mechanism, for part on workbench
Or the quick locking of equipment.
Background technology
The operating instrument installed on many platens, test platform, equipment mounting bracket, tripod at present, set
Standby, parts to be processed etc., such as needs Jing often to be installed manually and dismantled, and is required to a set of lock machine fast manually of mounted thereon fixation
Structure, to carry out at any time installing fixed or dismantle.By taking the retaining element on platen as an example, according to consulted reference materials and patent,
Mainly there are following several ways：
Mode the most frequently used at present, is the part on platen to be carried out admittedly by the combination of pressing plate and fixing bolt
It is fixed, pressing plate is placed on into part fixed position first when fixed, then pressing plate is compressed by tightening fixing bolt, so as to reach fastening
The purpose of part.The advantage of this mode is low cost, reliability height, has the disadvantage inconvenient operation, when each part is installed, all
Need first pressing plate is manually placed in behind part fixed position, then be fixed, when part is dismantled, first unclamp fixing bolt, then handss
It is dynamic that pressing plate is departed from part.
There is a kind of manual quick lock mechanism of platen in addition, by two fixing bolts, locking pressure plate, a bullet
Spring is constituted, by the way of two fixing bolt fastening locking pressure plates, so as to reach the purpose for fastening part thereon, this structure
It is cased with spring wherein on a fixing bolt, spring is located between platen and locking pressure plate, when part is installed, will
After which moves to the fixed position on platen, by tightening two fixing bolts, locking pressure plate is made by part and lathe worker
Fix as platform, when part is dismantled, by unclamping two fixing bolts, locking pressure plate is taken off automatically by contained spring with part
From, quickly part can be removed from platen, entirely the process of installation or removal part, is not required to handss move locking
Pressing plate.The advantage of this mode is：Part installing/dismounting is quick, reliable.Have the disadvantage：Part installation position on platen
Put, mounting means, part shape have certain restriction, after retaining mechanism unclamps, part can not be complete with the position of locking pressure plate
Depart from, outside needing part is moved to locking pressure plate first, just can be carried part up and down, this mechanism takes interior space dimension
It is larger.
In addition mounting hole etc. is changed to also by locking pressure plate is changed to annular, installing hole, to facilitate using manually will lock
Press plate to depart from retaining element.
, all there is certain restriction or inconvenient operation, particularly work as in several fastenings modes on the table above
Part installation fixing position is put when being difficult to reach with handss or instrument, or part is when being in obliquity, now consolidating on the table
Operation that is fixed and dismantling part, it will very difficult or cannot realize.
The content of the invention
For the defect of prior art, the invention provides a kind of quick lock mechanism, it is intended that can by rotary nut
Enable to be oriented to locking mechanism rotary motion up and down, so as near compressing component or release, away from part, mechanism of the present invention accounts for
With space is little, it is reliable lock, easy to operate, part easy installation and removal, do not limited by part installation site and shape.
A kind of quick lock mechanism, including：
