Description
Technical field
The present invention relates to the calibrating installation in measurement verification field, particularly a kind of cylinder gauge.
Background technology
Boats and ships are often wanted measurement host barrel wear situation when navigation, with the serviceable life of correct judgement cylinder sleeve; When cylinder gauge is ship's navigation, to a kind of special test equipment of diesel cylinder sleeve abrasion condition detection.
Cylinder gauge is to make according to the principle of three-point circle, and is as shown in Figure 1, and as the location fulcrum, the moving fulcrum of an other end is the spherical measuring head of dial gauge 2 by two fixed amount pin 1 for it, and the physical size of cylinder sleeve obtains through the dial gauge reading; The accuracy of cylinder gauge contacts the back through standard survey cap 3 and accomplishes zero with basal plane, the correctness of standard survey cap can be regulated adjustable inner core 4 and guaranteed.
If cylinder gauge loses accurate, the wear extent that obtains just has no reference value, so just must guarantee the correctness of cylinder gauge.
Because cylinder gauge is a special test equipment, its specification all is the nominal value of cylinder bore, and engineering department only provides schematic diagram, and technical requirement is: " through using cylinder gauge, the diameter of energy measurement cylinder sleeve bore ".As far as metrological service; Difficulty is just big; Both do not had vertification regulation, and also do not proofreaded equipment, and the dial gauge of installing on the cylinder gauge that is used for reading is " active "; How cylinder gauge is demarcated (be actually standard survey cap is demarcated), with what equipment calibrated, just become the task of top priority.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existing measuring technology, a kind of calibrating installation of cylinder gauge is provided.This calibrating installation should have simple in structure, is convenient to processing, can be efficiently, correctly the dimensional accuracy to cylinder gauge detects and adjusts, and is easy to use, and low cost of manufacture, solved the difficult problem that cylinder gauge can't be demarcated.
Technical solution of the present invention is following:
A kind of calibrating installation of cylinder gauge; Its characteristics are to be made up of two reference blocks, two connected positioning plates, fastening bolt and register pins; Its annexation is following: described reference block comprises identical two of structure; Each piece reference block has the spill R face that an end face of certain width, length and height rectangular block has regulation curvature; The two sides of this reference block have screw and dowel hole; Waist hole and dowel hole are arranged on the described connected positioning plate, and the R face on two reference blocks is discrete relatively and be clipped between two connected positioning plates, utilizes described fastening bolt and register pin to be formed by connecting through screw, the dowel hole of waist hole, dowel hole and the reference block of described connected positioning plate.
On the described reference block a screw and dowel hole are arranged, the R face on two reference blocks be worked on the lathe need size after, b connects with connected positioning plate.Waist hole and dowel hole are arranged on the connected positioning plate, and the device after the connection is the repetition measurement diameter on three coordinate measuring machine, can regulate the position of reference block if any error; Several times check qualified after; With dowel hole hinge processing back installing and locating pin, on three coordinate measuring machine, finally to measure again, the measurement project is: diameter and circularity; Physical size with diameter is labeled on the calibrating installation of cylinder gauge then, so that when cylinder gauge is calibrated, use.
Technique effect of the present invention is following:
On probation show that cylinder gauge calibrating installation of the present invention has simple in structure, be convenient to processing, can be efficiently, correctly the dimensional accuracy to cylinder gauge detects and adjusts, and is easy to use, and low cost of manufacture, solved the difficult problem that cylinder gauge can't be demarcated.
Description of drawings
Fig. 1 is the structural representation of existing cylinder gauge
Fig. 2 is the exploded view of cylinder gauge calibrating installation of the present invention
Fig. 3 is that cylinder gauge steadily is placed to the combination synoptic diagram in the cylinder gauge calibrating installation of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is described further, but should limit protection scope of the present invention with this.
See also Fig. 2 earlier; Visible by figure; The calibrating installation of cylinder gauge of the present invention; Be made up of two reference block a, two connected positioning plate b, fastening bolt c and register pin d, its annexation is following: described reference block a comprises identical two of structure, and each piece reference block a has the spill R face that an end face of certain width, length and height rectangular block has regulation curvature; The two sides of this reference block a have screw and dowel hole; On the described connected positioning plate b waist hole and dowel hole are arranged, the R face on two reference block a is discrete relatively and be clipped between two connected positioning plate b, utilizes described fastening bolt c and register pin d to be formed by connecting through screw, the dowel hole of waist hole, dowel hole and the reference block a of described connected positioning plate b.
R face on two reference block a be worked on the lathe need size after, b connects with connected positioning plate; Connect back repetition measurement diameter on three coordinate measuring machine, can regulate the position of reference block if any error; Check qualified after, with dowel hole hinge processing back installing and locating pin; On three coordinate measuring machine, finally measure at last, and physical size is labeled on the calibrating installation of cylinder gauge.
The method of application of cylinder gauge calibrating installation of the present invention is following:
Earlier cylinder gauge steadily being placed in the cylinder gauge calibrating installation of the present invention and (seeing shown in Figure 3), two fixed amount pin 1 are in horizontality, is to put into cylinder gauge calibrating installation of the present invention after the spherical measuring head compression of dial gauge 2 with moving fulcrum then; Swing back and forth up and down, find out the turning point that the dial gauge pointer rotates, according to the actual value of cylinder gauge calibrating installation prompting; Pointer is adjusted to prompting is worth corresponding position, take out cylinder gauge, standard is surveyed cap spare 3 contact with basal plane; At this moment if the position of dial gauge pointer should inconsistent, can be regulated the position of adjustable inner core member 4 with instrument with consistent with the cylinder gauge calibrating position; After treating unanimity; Available " 502 glue " is fixed, and the outer big plane of then standard being surveyed cap spare 3 polishes, and the calibration operation of cylinder gauge is accomplished.
Shows that through on probation cylinder gauge calibrating installation of the present invention has simple in structure, be convenient to processing, can be efficiently, correctly the dimensional accuracy to cylinder gauge detects and adjusts, and is easy to use, and low cost of manufacture, solved the difficult problem that cylinder gauge can't be demarcated.
