Abstract
The utility model discloses a kind of levelling device of precision equipment work top, it includes firm banking, four pillars in rectangular layout are fixed with firm banking, it has been threaded connection stop sleeve on each strut respectively, there is work top in four stop sleeve upper supports, mutual corresponding sphere pit is respectively equipped between each stop sleeve top surface and work top bottom surface and steel ball is clamped with respectively, extension spring is arranged between firm banking and work top, steel ball is clamped between stop sleeve and work top.Beneficial effect is：Simple structure, easy to adjust, long service life；Due to having used steel ball to carry out transition connection between work top and stop sleeve, therefore the power of non-vertical direction will not be applied in leveling process B-C post to work top, the flexural deformation that work top can be avoided to produce because of stress, it is ensured that the flatness of work top.
Description
Technical field
This utility model belongs to a kind of machinery, more particularly to a kind of levelling device of precision equipment work top.
Background technology
At present, in machine industry, precision equipment work top can be affected by working environment, such as temperature,
Humidity, vibration and load etc., if being unable to the flatness of effective control work top, influence whether the crudy of workpiece, because
This, how research carries out leveling to work top, and to research and develop corresponding levelling device be very necessary.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of simple structure, is easy to adjust, ensure that work
The levelling device of the precision equipment work top of table top flatness.
To solve the above problems, this utility model is adopted the following technical scheme that：
A kind of levelling device of precision equipment work top, including firm banking, four are fixed with firm banking is in
The pillar of rectangular arrangement, has been threaded connection stop sleeve on each strut respectively, in four stop sleeve upper supports
There is work top, mutual corresponding sphere pit is respectively equipped between each stop sleeve top surface and work top bottom surface and is divided
Steel ball is not clamped with, extension spring is arranged between firm banking and work top, make steel ball stop sleeve is clamped in work
Between table top.
Used as further preferred, the pillar is ladder shaft-like, and its top is provided with external screw thread, and its bottom is fixed by screw
On firm banking.
Used as further preferred, the extension spring is two and is respectively provided in the middle of two pillars of the same side, at fixed bottom
Seat with mutually corresponding extension spring link plate is respectively equipped with work top.
The beneficial effects of the utility model are：Simple structure, easy to adjust, long service life；Due to work top with
Use steel ball to carry out transition connection between stop sleeve, therefore non-hanging down will not have been applied to work top in leveling process B-C post
Nogata to power, the flexural deformation that work top can be avoided to produce because of stress, it is ensured that the flatness of work top.

Specific embodiment
As shown in FIG. 1 to 3, the levelling device of a kind of precision equipment work top that this utility model is related to, including one
Individual firm banking 1, firm banking 1 are cuboid tabular, and four pillars 2 in rectangular layout, institute are fixed with firm banking 1
Pillar 2 is stated for ladder shaft-like, its top is provided with external screw thread, and its bottom is fixed by screws on firm banking 1.
Stop sleeve 3 has been threaded connection respectively on each 2 top of pillar, has been had in four 3 upper supports of stop sleeve
One work top 5, is respectively equipped with mutual corresponding sphere recessed between each 3 top surface of stop sleeve and 5 bottom surface of work top
Hole 8, and steel ball 4 is clamped with respectively between mutual corresponding sphere pit 8.
Extension spring 7 is arranged between firm banking 1 and work top 5, makes steel ball 4 stop sleeve 3 is clamped in work
Between table top 5.The extension spring 7 is preferably two and is respectively provided in the middle of two pillars 2 of the same side, in firm banking 1 and work
Make to be respectively fixed with mutual corresponding extension spring link plate 6 in the middle of two pillars 2 of the same side on table top 5,7 two ends of extension spring are distinguished
Hang on the hook of corresponding extension spring link plate 6.
Although embodiment of the present utility model is disclosed as above, which is not restricted in description and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the general concept limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to and shown here as the legend with description with new.
