Description
Technical field
The present invention relates to measuring instrument field, concretely relate to the counter weight construction of a kind of pole coordinate measuring apparatus.
Background technology
In the large-scale precision equipment fields such as steamer, aviation, military project, the measurement right and wrong of pole coordinate, airscrew pitch etc. are usually shown in and necessity.But during at present to the pole coordinate of workpiece, the measurement to airscrew pitch, if artificially carrying out the measurement of X-coordinate, Y coordinate, angle, workload is huge, and error easily occurs.Thus generally use pole coordinate measuring apparatus to measure.When but the polar coordinate measurement device used at present uses, the support arm at scriber place is arranged on the side of polar coordinate measurement device rotary axis, workpiece for measurement is connected with measuring instrument by the scroll chuck bottom rotary axis, during measurement, scriber position is constantly moved, the center of gravity of pole coordinate measuring apparatus entirety can produce change along with the change of scriber position, therefore, if only arrange a fixing balancing weight in the side relative with scriber, then it cannot be guaranteed that the center of gravity of pole coordinate measuring apparatus is always positioned at initial position, thus cause coordinate system that measuring instrument sets up in the range of fluctuate, affect certainty of measurement.
Summary of the invention
The present invention proposes the counter weight construction of a kind of pole coordinate measuring apparatus, the problem of center of gravity continuous moving influence certainty of measurement during to solve the work of pole coordinate measuring apparatus in prior art, it is achieved the purpose of auto-control pole coordinate measuring apparatus center of gravity.
The present invention is achieved through the following technical solutions:
A kind of counter weight construction of pole coordinate measuring apparatus, including flat board, one end of described flat board long axis direction is fixed with connecting plate, described connecting plate is vertical with described flat board, it is further fixed on driving means on described flat board, the guide rail being fixed on planar surface it is provided with between described driving means and connecting plate, and can be along the balancing weight of slide, described balancing weight is connected with the drive end of described driving means；Described planar surface is additionally provided with electrolevel, single-chip microcomputer, and the signal receiving end of described single-chip microcomputer is connected with electrolevel, signal output part is connected with driving means.The problem of center of gravity continuous moving influence certainty of measurement when working for pole coordinate measuring apparatus in prior art, the present invention proposes the counter weight construction of a kind of pole coordinate measuring apparatus.Guide rail and supporting balancing weight are set on described flat board, described connecting plate is for being connected with the rotary axis of polar coordinate measurement instrument, connecting plate is fixed with flat board, and flat board is mobile with connecting plate, and connecting plate then rocks along with the rocking of measuring instrument rotary axis being attached thereto.Described balancing weight is connected with the drive end of described driving means, and driving means controls balancing weight position on guide rail, regulates and controls, with this, the center of gravity that measuring instrument is overall.Described planar surface is additionally provided with electrolevel, single-chip microcomputer.Electrolevel is existing horizontal sensor device, it it is the measuring appliance measuring tested surface relative level tiny inclination angle with the equilibrium principle of electric capacity pendulum, there is advantage highly sensitive, that precision is high, utilize the horizontality of the electrolevel monitoring flat board arranged at planar surface.Along with measuring instrument scriber constantly moving during measuring, can drive the inclination to the left or to the right of measuring instrument rotary axis, this is tilted through described connecting plate and is transferred on flat board, causes flatbed horizontal state to change.This change is monitored by electrolevel, and tilt signals is transferred to described single-chip microcomputer, the drive end of driving means described in Single-chip Controlling is to the rightabout motion tilted, described balancing weight is i.e. driven to move along the rightabout tilted on guide rail, so that flat board remains level, the active force being concurrently applied to measuring instrument rotary axis is different, thus by adjusting the distance regulation and control measuring instrument entirety center of gravity of balancing weight distance rotary axis, when measuring instrument scriber moves, balancing weight moves the most voluntarily, pole coordinate measuring apparatus entirety center of gravity is made to be in same position all the time, reduce measure error, improve certainty of measurement, realize auto-control pole coordinate measuring apparatus center of gravity purpose.
Preferably, described balancing weight is lead.In common metal, metallic lead has greater density, use lead as balancing weight, be conducive to increasing the total quality of the present invention, make the present invention after being connected to pole coordinate measuring apparatus, measuring instrument entirety center of gravity is partial to side of the present invention, thus reduces scriber and move the impact on measuring instrument entirety center of gravity.Use the metallic lead that quality is bigger as balancing weight simultaneously, utilize the density that metallic lead is bigger, it is possible to increase the counterweight modification scope of the present invention.
Further, described several screwed holes of connecting plate surface configuration.By screwed hole so that using bolt the present invention to be connected on the rotary axis of pole coordinate measuring apparatus.
Further, described connecting plate and plate welding.Welding is used to guarantee the firm and reliable connection between connecting plate and flat board.And welding manner does not increase miscellaneous part and is attached, it is to avoid other connection member stress deformations affect the transmission of stress.
The present invention compared with prior art, has such advantages as and beneficial effect:
The counter weight construction of the present invention a kind of pole coordinate measuring apparatus, flat board arranges driving means, guide rail, balancing weight, electrolevel, single-chip microcomputer, use electrolevel monitoring flatbed horizontal situation, and moved to the rightabout tilted by the drive end of Single-chip Controlling driving means, described balancing weight is i.e. driven to move along the rightabout tilted on guide rail, so that flat board remains level, pole coordinate measuring apparatus entirety center of gravity is made to be in same position all the time, reduce measure error, improve certainty of measurement, realize auto-control pole coordinate measuring apparatus center of gravity purpose.
