The utility model has the advantage of high measuring precision.
Description
Technical field
The utility model relates to calibration equipment, relates in particular to a kind of stereometry equipment, specifically is meant a kind of stereometry liquid level elevating mechanism.
Background technology
When some solids (like counterweight) etc. are carried out stereometry; A kind of method commonly used is to utilize Archimedes' principle with solid its quality of weighing in air neutralising fluid (like water) respectively; According to the certain mathematical model it is carried out modeling then, thereby calculate the volume of weighing solid.
When in liquid, solid being carried out weighing; Classic method is directly to immerse tested solid in the liquid; The container of this measuring method storaging liquid is fixed, and liquid level also is motionless, and the degree of depth that when solid is immersed liquid, immerses like this is different; And because solid normally is suspended on quality meter lower end; The quality meter is transferred the swing that causes solid when immersing liquid easily together with fixing, and the quality meter often moves repeatedly in addition also can influence the precision of its measurement, and then has influenced the precision of cubing.
The utility model content
The technical matters that the utility model will solve is, provides a kind of tested solid and quality meter to fix and utilizes the up-down of liquid level to make tested solid immerse stereometry liquid level elevating mechanism liquid, that measuring accuracy is higher.
The technical solution of the utility model is; A kind of stereometry liquid level elevating mechanism is provided; Comprise liquid storage container and station carrier to be measured; Station carrier to be measured is suspended on the top of liquid storage container, also comprises lifting drive and adjustable height control device, and described lifting drive drives the lifting action that liquid storage container is done predetermined stroke under the control of adjustable height control device.
After adopting above scheme, liquid storage container can go up and down under the driving of lifting drive, and the stroke of up-down receives the control of adjustable height control device; Station carrier to be measured like this is that suspension is fixed on the liquid storage container top, and when liquid storage container rose, the solid that is placed on the station carrier to be measured can immerse in the liquid; The tested solid of this mode is difficult for rocking; The quality meter also is fixed in addition, is not vulnerable to the influence of repeated measurement, thereby the precision of measuring is more guaranteed.
As preferably; Described lifting drive comprises support and rack-mount drive motor, guide pillar, lead screw assembly, back up pad and controller; Lead screw assembly drives carrying liquid storage container back up pad and on guide pillar, moves up and down under the driving of drive motor, described drive motor is electrically connected with controller.This optimal way adopts lead screw assembly as lift drive mechanism, and rising or falling speed is even, and precision is higher.
As preferably, described adjustable height control device comprises controller and at least two optical couplers that are used to respond to the back up pad height and position, and described optical coupler is electrically connected with controller.Whether this preferred version utilizes optocoupler mensuration back up pad to go up and down to put in place, is quick on the draw, and reliability is high.

Embodiment
For the technical scheme of the utility model better is described, be described in detail below in conjunction with the embodiment of accompanying drawing to the utility model.
Shown in accompanying drawing; A kind of stereometry liquid level elevating mechanism; Comprise liquid storage container 1 and station carrier 2 to be measured; Station carrier 2 to be measured is suspended on the top of liquid storage container 1, also comprises lifting drive 3 and adjustable height control device 4, and described lifting drive 3 drives the lifting action that liquid storage container 1 is done predetermined stroke under the control of adjustable height control device 4; In the present embodiment; Described lifting drive 3 comprises support 3.1 and is installed in drive motor 3.2, guide pillar 3.3, lead screw assembly 3.4, back up pad 3.5 and the controller 5 on the support 3.1, and lead screw assembly 3.4 moves up and down on guide pillar 3.3 driving carrying liquid storage container 1 back up pad 3.5 driving of drive motor 3.2 under, and described drive motor 3.2 is electrically connected with controller 5; Described adjustable height control device 4 comprises controller 5 and three optical couplers 4.1 that are used to respond to back up pad 3.5 height and positions, and described optical coupler 4.1 is electrically connected with controller 5.
Should explain that at this lead screw assembly 3.4 generally comprises compositions such as leading screw, ball nut, it utilizes the rotating band dynamic component of motor to do the oscilaltion campaign for this area prior art commonly used, and its concrete connection mode is launched admittedly no longer in detail.
In the above-described embodiments, a kind of preferred forms of the utility model is described, obviously; Under the inventive concept of the utility model; Still can make a lot of variations and improvement, substitute, go up and down with air cylinder driven liquid storage container 1 like described lifting drive 3 cylinder also capable of using; Described like this adjustable height control device 4 is promptly controlled through the stroke of cylinder, so equally also can reach the purpose that liquid storage container 1 goes up and down.At this, should explain that any change of under the inventive concept of the utility model, being made all will fall in the protection domain of the utility model.
