Abstract
The utility model relates to a measuring instrument, particularly a special globe- shaped measuring head micrometer which measures the module of an involute spline of 30 DEG or an involute gear of 20 DEG. The utility model is characterized in that the end parts of a standard pillar and a measuring pillar are directly made into a globe-shaped measuring head, or can also be inlaid with a globe-shaped measuring head. The utility model has the advantages of high measuring precision, and simple and convenient measurement, and is an ideal and novel special measuring tool.
Description
The utility model relates to a kind of surveying instrument, especially measures the special-purpose spheric probe milscale of the modulus of 30 ° of involute splines or 20 ° of involute gears.
In the prior art, when the workpiece of 30 ° of involute splines or 20 ° of involute gears was tested, the method for inspection of employing is people's number number of teeth normally, then with measuring rod, after analysis-by-synthesis is calculated the value that just draws modulus.The shortcoming of doing like this is: 1. measurement result is inaccurate; 2. waste a large amount of man-hours; 3. waste product appears easily; 4. easily axial error is included when rod is measured with measuring; 5. measure excellent precision own and do not satisfy desirable measuring accuracy, in addition,,, be difficult to measure the surface of arc because of the end of benchmark post and measurement column is plane directly with conventional miking.
The purpose of this utility model is to overcome the deficiency of known technology and a kind of measuring accuracy height is provided, and measures simple and conveniently, is particularly suited for measuring the special-purpose spheric probe milscale of the modulus of 30 ° of involute splines and 20 ° of involute gears.
The utility model is achieved in that
Spheric probe is directly made in end at benchmark post and measurement column, perhaps also can be to stud with spheric probe.
The utility model has the advantages that: because of the end of benchmark post and measurement column is a spheric probe, when therefore measuring 30 ° of involute splines and 20 ° of involute gear moduluses, is beneficial to very much and measures this curved surfaces, the result of measurement is very accurate.Milscale using method routinely when using the utility model, easy to use, be a kind of novel special measurement instrument.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of another embodiment of the utility model.
Below in conjunction with accompanying drawing the utility model embodiment is further described:
Embodiment 1: benchmark post 1 and measurement column 4 are installed on the chi frame 10, directly be shaped on spheric probe 2,3 in the end of benchmark post and measurement column, be shaped on above that the sleeve 8 of chi 7 is read in fine setting and tangent screw 9 is installed on the chi frame and may command measurement column flexible, can read chi and read measured value by being engraved in the main scale 6 on the chi frame and being engraved in fine setting on the sleeve thus.Clamp 5 also can position measurement column on the chi frame.
Embodiment 2: only direct spheric probe built in benchmark post and measurement column end is changed into the end that the spheric probe 11,12 that makes is set in benchmark post and measurement column and get final product, other structure is with embodiment 1.
When using the utility model, because of accuracy requirement, it is manufactured the precision permissible error and is ± 0.002 millimeter when manufacturing spheric probe, measurement column and benchmark axis of a cylinder are less than 0.005 millimeter to error, select the spheric probe of different size in addition for use at the specification of 30 ° of different involute splines and 20 ° of involute gears.Only the diameter of 30 ° of its corresponding spheric probes of involute spline of part specification is listed as follows below:
| Nominal size * modulus * the number of teeth | Spheric probe diameter (millimeter) | |
| 1 | 25×1.25×18 | 2.75 |
| 2 | 35×1.25×26 | 2.5 |
| 3 | 55×2×26 | 4 |
| 4 | 75×2×36 | 3.5 |
| 5 | 80×3×25 | 6 |
Claims (1)
1, a kind of special-purpose spheric probe milscale, reading chi, tangent screw, clamp etc. by chi frame, benchmark post, measurement column, sleeve, main scale, fine setting constitutes, it is characterized in that: spheric probe is directly made in the end at benchmark post and measurement column, or studs with spheric probe.
