Description
Technical field
The utility model relates to the surveying instrument field, specifically is a kind of digital display angle calliper.
Background technology
When inner diameter of workpiece, external diameter or thickness are measured, usually adopt calliper to measure.Plain calliper gauge can only be measured air line distance, can not carry out measurement of angle, has limited the application of calliper; And precision, the error measured depend on machining, assembly precision, so manufacturing cost is high; The gage beam of plain calliper gauge is long more, and error is big more, and large-sized measurement does not suit to carry out.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and provide a kind of simple in structure, process and assemble is less demanding, low cost of manufacture, can realize the measurement of inside and outside footpath of workpiece and thickness, can realize the multifunctional digital angle calliper of measurement of angle again.
The purpose of the utility model is to realize through following technical scheme:
A kind of digital display angle calliper comprises measurement display unit, rotating shaft and two gage beams of being provided with sensor, and different with prior art is: also comprise processing unit, processing unit is connected with the measurement display unit;
Two but gage beam is rotationally connected through rotating shaft 360o, and the inside and outside both sides of every gage beam all are made as measurement of angle face, is respectively equipped with corresponding linear measure longimetry termination on two gage beams.
Described linear measure longimetry termination is a circular arc.
Article two, the center of two circular arcs on the gage beam can go to coincidence at gage beam when described rotating shaft is rotated.
Said sensor is absolute type or incremental capacitor grid transducer.
The center of two circular arcs and the center of rotating shaft be fixed value apart from length; Processing unit through including software is according to the account form of software; Realize measurement of angle commentaries on classics line measurement; Point of contact through two circular arcs in linear measure longimetry termination contacts with measured piece carries out linear measure longimetry, obtains length value, makes this angle calliper applicable to angle and measurement of length.
This angle calliper is continued to use the production technology of existing Digit Display Angle Ruler; Technical maturity, reliability height; The four measuring face of two gage beams and two straight lengths are measured the termination through standard machinery processing, and the mode through software processes very easily realizes and guaranteed manufacturing and service precision again.
The utility model can be widely used in the big inside and outside footpath of workpiece on the industries such as carpenter, building, installation, thickness, inside and outside angle and measurement of length.
The utlity model has simple in structure, can realize inside and outside footpath, thickness, inside and outside angle and linear measure longimetry, multi-functional advantage, and can calibrate through software processing mode, low cost of manufacture helps popularizing and promoting.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model content is done further to set forth, but be not qualification the utility model.
Embodiment:
With reference to Fig. 1-Fig. 3, a kind of digital display angle calliper comprises measurement display unit 2, rotating shaft 3 and two gage beams 1 of being provided with sensor, also comprises processing unit 6, and processing unit 6 is connected with measurement display unit 2;
Two but gage beam 1 is rotationally connected through rotating shaft 3 360o, and the inside and outside both sides of every gage beam 1 all are made as measurement of angle face, is respectively equipped with corresponding linear measure longimetry termination 7 on two gage beams 1.
Linear measure longimetry termination 7 is a circular arc, is arranged on the end of gage beam 1.Linear measure longimetry termination 7 also can be right cylinder, is arranged on the gage beam 1.
Article two, the center 5 of two circular arcs on the gage beam 1 can go to coincidence when gage beam 13 rotations around the shaft.
Sensor is absolute type or incremental capacitor grid transducer.
Particularly; Measuring display unit 2 mainly is made up of sensor, the processing unit 6 that includes software, function display module and Connection Block; Sensor, function display module and processing unit 6 are arranged in the Connection Block, and two gage beams 1, Connection Block and rotating shaft 3 matched togethers make two gage beams 13 do the relative angular displacement motion around the shaft; And make survey sensor detect the relative angle displacement that two gage beams, 1 motion back produces; After treated unit 6 is handled, through the function display module The measured results show is come out, data presented is the size value of workpiece calibration part.
The end of two gage beams 1 is linear measure longimetry termination 7, can realize the measurement of inside and outside footpath of workpiece and thickness.
Four measuring face 4 can be realized the measurement of the inside and outside angle of workpiece.
The center 5 of two circular arcs is fixed value with the center of rotating shaft 3 apart from length; Two circular arcs also are fixed value, and the processing unit 6 through including software again is according to the account form of software; Realize the measurement of angle commentaries on classics straight line; When measuring length,, can obtain length value as long as the surperficial point of contact of linear measure longimetry termination 7 circular arcs contacts with measured piece.
The center 5 of two circular arcs 3 goes to when overlapping at gage beam 1 around the shaft, also can carry out Zero positioning, eliminates the rigging error of benchmark, reduces matching requirements, reduces cost, and more is prone to realize producing in batches.
Adopt the absolute type capacitor grid transducer, have the characteristic of absolute zero position memory, only need a Zero positioning, can eliminate the error before assembling and measuring; The incremental capacitor grid transducer needs repeatedly to demarcate, and all need carry out Zero positioning before promptly each the use.
