Abstract
The invention relates to a disc spring string swinging balancing mechanism for a workbench of a 2000mm numerical control polishing machine. The disc spring string swinging balancing mechanism mainly aims at solving the problem that existing balancing mechanisms of the heavy-punch type, the hydraulic type and the like cannot meet the requirement of gravitational balancing of a workbench of a large-size polishing machine tool. The disc spring string swinging balancing mechanism is characterized in that the mechanism comprises the workbench (1), a workbench base (2) and a disc spring string (4); a disc spring string lower support (5) and a disc spring string upper support (3) are fixed to the lower end and the upper end of the disc spring string (4) correspondingly; the disc spring string lower support (5) is fixed to the workbench base (2) and located under a workbench overturning center (A); and the disc spring string upper support (3) is fixed to the bottom face of the workbench (1) and located at the left side of the workbench overturning center (A) in the horizontal direction. By means of the mechanism, gravitational balancing can be conducted on overturning of the workbench of the 2000mm numerical control polishing machine, and the mechanism is stable and reliable in function.
Description
Technical field
The present invention relates to machining equipment field, specifically one kind is for 2000mm numerical control polishing working platform overturning
Disc spring string swing balanced controls.
Background technology
In precision optics machining eyeglass field, with social development, precision optics eyeglass does bigger and bigger, and current throwing
Light lathe cannot adapt to the processing of major diameter optical glass, for this reason, have developed large-sized numerical control buffing machine.And this lathe is due to chi
Very little excessive, its workbench, in upset measurement, topples protection for the ease of operation and increase, needs the upset to workbench to carry out
Gravitational equilibrium, and existing Weight type, hydraulic cylinder type isoequilibrium mechanism all cannot meet equilibrant dynamic change demand.
Content of the invention
In order to overcome existing Weight type, hydraulic cylinder type isoequilibrium mechanism cannot meet large scale burnishing machine workbench
The deficiency of gravitational equilibrium, the present invention provides a kind of disc spring string for 2000mm numerical control polishing machine worktable to swing balanced controls,
This mechanism can carry out gravitational equilibrium to 2000mm numerical control polishing working platform overturning, and function-stable is reliable.
The technical scheme is that：A kind of disc spring string for 2000mm numerical control polishing machine worktable swings balancing machine
Structure, including workbench, table base, also includes disc spring string, described disc spring string upper and lower ends are respectively fixed with lower of disc spring string
Frame and disc spring string upper bracket, described disc spring string lower carriage is fixed on table base, and disc spring string lower carriage is located at workbench
The underface at upset center, described disc spring string upper bracket is fixed on workbench bottom surface, and disc spring string upper bracket horizontal direction is upper
In working platform overturning center left.
Described disc spring string lower carriage and table base are connected by self-aligning roller bearing pair, described disc spring string upper bracket and
Workbench connects by self-aligning roller bearing is secondary.
The present invention has the advantages that：Due to taking such scheme, between table base and workbench, pass through dish
Spring string is connected, and during working platform overturning, disc spring string carrier parts centre-to-centre spacing changes, and disc spring is compressed, loosened, balance arm of force change, from
And change trimming moment.When workbench is turned to horizontal state around upset center from vertical state, gravitational moment is first from big to small, then from little
To greatly, the trimming moment of disc spring string is also from big to small first, more from small to large, preferably meeting equilibrant dynamic change needs
Ask, function-stable is reliable.
Brief description
Fig. 1 is the structural representation of table vertical state of the present invention；
Fig. 2 is the structural representation of driving water level state of the present invention.
In figure 1- workbench, 2- table base, 3- disc spring string upper bracket, 4- disc spring string, 5- disc spring string lower carriage, A- turns over
Turn center, B- workbench barycenter, h- decrement.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings：
Shown in Fig. 1, Fig. 2, a kind of disc spring string for 2000mm numerical control polishing machine worktable swings balanced controls, including work
Platform 1, table base 2, also include disc spring string 4, model A100-1 of described disc spring（GB/T1972（108）, disc spring string 4 by
Several described disc springs are connected in series.Described disc spring string 4 upper and lower ends are respectively fixed with disc spring string lower carriage 5 and disc spring string
Upper bracket 3, described disc spring string lower carriage 5 is connected on table base 2 by self-aligning roller bearing pair, and disc spring string lower carriage
5 underfaces being located at working platform overturning center A, wherein disc spring string lower carriage 5 center vertical direction is apart from table base 2 bottom surface
For 580mm, horizontal direction is positioned at the underface of working platform overturning center A.Described disc spring string upper bracket 3 passes through self-aligning roller bearing
Pair is connected to workbench 1 bottom surface, and is located in disc spring string upper bracket 3 horizontal direction on the left of the A of working platform overturning center, distance work
Platform upset center A is 120mm, and disc spring string upper bracket 3 center vertical direction is 74mm apart from table base 2 bottom surface.
When working platform overturning, due to disc spring string 4 upper bracket bearing centre with workbench around upset center A upset when,
The upper and lower carriage center of disc spring string will be compressed, loosened away from change, disc spring.When workbench be in upset stroke the vertical state in two ends with
During horizontal state, decrement h of disc spring is maximum, and equilibrant is also maximum, and the balance arm of force is also long, now, due to the weight of workbench barycenter
The arm of force is the longest, needs balanced moment also maximum.When workbench barycenter B from two ends around upset center A to upset overcentre
During upset, when weight arm is gradually reduced, disc spring string upper bracket center is with workbench to upset overcentre upset, disc spring string length
Elongated, equilibrant is gradually reduced, and the balance arm of force also shortens.Workbench is turned to level around working platform overturning center from vertical state
State, gravitational moment is first from big to small, more from small to large, the trimming moment of disc spring string is also from big to small first, more from small to large, preferably
Meet equilibrant dynamic change demand.
