Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of Miniature precision adjustable supports.
Background technology
In the production and processing of machine components, part is pressed from both sides in the enterprising luggage of mechanical equipment, and due to mechanical equipment, there are one in itself
Fixed position error can not ensure the accuracy of form and position between part surface to be machined and reference plane by clamped one time, usually need
Micro height is carried out to part again to adjust.When carrying out micro height to part and adjusting, generally use hammer to part into
Row is slight to be tapped, and part is made to carry out micro adjustment, but tapping can cause the element precision of part clamping face to be destroyed, and cause part
The accuracy of form and position of drawing requirement cannot be met.
For the problem present on, people make miscellaneous improvement, and some has also applied for patent, such as China is specially
Sharp documents and materials disclose a kind of lathe foot pad [application number：201320348213.4；Application publication number：CN203330696U],
Including pedestal, on pedestal there is mounting groove, be equipped with sliding block and elevator in mounting groove, elevator is located at the top of sliding block, sliding block
Upper surface there is inclined-plane one, the lower surface of elevator has the inclined-plane two to match with inclined-plane one, the upper table mask of elevator
There is ball bowl, be equipped with the ball ring to match with ball bowl in ball bowl, the middle of ball ring is fixed with fixing bolt, the one side of pedestal
Adjustment bolt is axially fixed with by fixed structure, the inner end of adjustment bolt is connected with sliding block screw thread.
When this kind of lathe height of foot pad is adjusted, adjusting bolt is rotated, moves axially sliding block relative adjustment bolt, by
The axial movement of sliding block drives the vertical shift of elevator, although lathe foot pad is adjusted for the height of lathe, this kind of structure
The height and levelness for being equally applicable to other mechanical devices or parts are adjusted.But the lathe foot pad of this kind of structure adds in production
, it is necessary to which the circumferential direction in adjusting bolt opens up annular groove in work, while open up on base side wall corresponding with annular groove
