Description
(1) technical field:
The utility model relates to a kind of inside dimension precision measurement utensil, specifically a kind of single lever-type micrometer inside caliper.
(2) background technology:
Existing mechanical single pole micrometer inside caliper is a principle of utilizing screw pair, distance separating between the spherical measurement face in two ends on the main body bar is carried out the inside dimension measuring appliance of reading through the microdrum scale.The measuring appliance of measuring as inside dimension also have a kind of commonly used be exactly the internal diameter scale.And present existing digimatic micrometer is a principle of utilizing electronic surveying, numeral to show, by sensor with screw pair on the chi frame between two measurement faces distance separating be converted into the outside micrometer that numeral shows and carry out reading.
At present, though mechanical single pole micrometer inside caliper, internal diameter scale and digital display outside micrometer all have use in reality, in the deficiency that self is all arranged aspect the measurement inside dimension separately! Though machinery single pole micrometer inside caliper is widely used for the measurement of inside dimension; And the mechanism design errors of principles is zero (meeting abbe ' s principle); But because its two spherical measurement face is to do the overhanging motion of rigidity and measure along with the motion of screw pair when measuring; (diametric(al) in tested inside dimension needs maximizing for ergometry during measurement and the correctness of measuring position; Axial cross section domestic demand in tested inside dimension is sought minimum value) depend on operator's operation skill fully, and be difficult to guarantee to obtain correct measuring position.Therefore, the consistance of measurement result and reliability are difficult to guarantee.Simultaneously, digitizing output can not be carried out, thereby the automation data processing can't be realized measurement result; The internal diameter scale also is widely used for the measurement of inside dimension; And owing to adopted the measuring head of an end float extension to be equipped with the centering that bridge is protected in the location; Can solve the problem that guarantees the accuracy of measuring position in the measurement well; But itself is sinusoidal leverage owing to what adopt, and the mechanism principle error increases and increases rapidly with range, thereby has limited the path increment of internal diameter scale one-shot measurement; Handle though digital display outside micrometer reading is directly perceived, also can export measurement result to the computer realization automation data, can't carry out the measurement of inside dimension.
(3) utility model content:
The purpose of the utility model provides a kind of simple in structure, complete function, if adopt digital display technology also can realize the single lever-type micrometer inside caliper that digitizing output measurement result is carried out the automation data processing.
Can realize the single lever-type micrometer inside caliper of above-mentioned purpose; Comprise the main body bar; Main body bar two ends are provided with measuring head and micrometer parts respectively; Spherical measuring head is located at the end of micrometer parts, and different is said measuring head is fixedly gauge head or elastic telescopic gauge head, and said main body bar is provided with digital display mechanism.
The little displacement measurement of said elastic telescopic gauge head is that numeral shows or the scale indication.
On this basis, said micrometer parts can be joined groove indication screw pair or joined numeral demonstration screw pair or join the translational micrometer mechanism.
Therefore, the utility model can not only maintain the total characteristic of mechanical single pole micrometer inside caliper, internal diameter scale and digital display outside micrometer through the combination of different structure, also the function of each measurer is further expanded, and satisfies the specific (special) requirements of different measuring environment.
Bridge is protected in also configurable location on the said main body bar.
Said digital display mechanism comprises digital display sensor and measuring unit and display unit.
The advantage of the utility model:
1, the utility model single lever-type micrometer inside caliper is simple and reasonable for structure, and measurement range is big, easy to operate, and manufacturing process requirement is not high yet, so its cost of manufacture is lower, also can reach very high measuring accuracy.
2, the utility model single lever-type micrometer inside caliper is that the function of set mechanical single pole micrometer inside caliper, internal diameter scale and digimatic micrometer is the innovative combination form of one.
(4) description of drawings:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Figure number sign: 1, main body bar; 2, measuring head; 3, spherical measuring head; 4, micrometer parts; 5, digital display mechanism.
(5) embodiment:
Below in conjunction with accompanying drawing the utility model technical scheme is further advanced explanation:
The utility model single lever-type micrometer inside caliper is the same with former mechanical single pole micrometer inside caliper; Comprise main body bar 1 parts; Main body bar 1 two ends are provided with measuring head 2 and micrometer parts 4, and micrometer parts 4 ends are provided with spherical measuring head 3, and different is in main body bar 1, to be provided with digital display mechanism 5; Digital display mechanism 5 comprises digital display sensor and measuring unit and display unit; And measuring head 2 is arranged to the elastic telescopic gauge head, and micrometer parts 4 adopt grooves indication screw pairs (or digital display screw pair or translational micrometer device), as shown in Figure 1.
In the single lever-type micrometer inside caliper of said structure; The little displacement of elastic telescopic gauge head is passed to displacement transducer; And the little displacement of elastic telescopic gauge head is converted into electric signal and handles through interlock circuit by sensor, show measurement result value by the display of digital display mechanism 5.
Can be arranged to fixedly gauge head like measuring head 2 according to measurement needs conversion measuring head 2 and micrometer parts 4, the micrometer parts 4 alternative numerals that adopt show screw pair or translational micrometer mechanism.
Also can on main body bar 1, dispose parts such as location bridge plate according to the needs that use.
