Abstract

The invention discloses a device for detecting a discontinuous conical rotating body angle, which comprises a reference block, a detected block and a correction block, wherein the detected block is arranged on the reference block; a positioning mandrel is arranged in the detected block; a dial indicator is arranged on the detected block; a spring is arranged between the detected block and the dial indicator; and the correction block is provided with a protrusion. The device has the advantages that: the discontinuous conical rotating body angle detected by the device is more accurate; and the device is convenient for calculation, has a simple structure, and meanwhile reduces the inspection cost.

Description

A kind of device that detects discontinuous taper rotary body angle
Technical field
The invention belongs to the pump technology field, particularly a kind of device that detects discontinuous taper rotary body angle.
Background technology
Each blade of pump class impeller all is discontinuous, is generally discontinuous taper rotary body.Whether the angle of discontinuous taper rotary body the qualified usability that is directly connected to product, we detect the angle of discontinuous taper rotary body, the method of generally taking is to design and produce a point of theory imitation body, whether the detect by an unaided eye gap of the tested part conical surface and the profiling conical surface, side judges evenly whether angle is qualified, what have detects with three-dimensional, but the workpiece conical surface is discontinuous, measuring point is not necessarily just surveyed on same straight line, and the inaccurate and inspection cost of the value that calculates is than higher.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, providing a kind of can address the above problem, and the angle that calculates is accurate, and the not high device of inspection cost.
A kind of device that detects discontinuous taper rotary body angle, comprise reference block, tested and proof-reading block, described tested is arranged on the reference block, be provided with positioning core axle in described tested, described tested is provided with dial gauge, be provided with spring between described tested and the dial gauge, described proof-reading block is provided with projection.
The invention has the beneficial effects as follows: the discontinuous taper rotary body angle that device of the present invention detects is more accurate, and convenience is calculated, apparatus structure is simple, has also reduced inspection cost simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of proof-reading block of the present invention;
Fig. 3 is the front view of the discontinuous taper rotary body of testing product of the present invention;
Fig. 4 is the vertical view of Fig. 3.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: a kind of device that detects discontinuous taper rotary body angle, comprise reference block 2, tested 3 and proof-reading block 7, described tested 3 is connected on the reference block 2 by holding screw 8, be provided with positioning core axle 6 in described tested 3, positioning core axle 6 is step axles, be to decide the tested part center, described tested 3 is provided with dial gauge 5, be provided with spring 4 between described tested 3 and the dial gauge 5, described proof-reading block 7 is provided with projection 11, and the height of projection 11 is L.
As Fig. 1, shown in Figure 3, the angle angle ﹠amp that we will detect; The angle during detection, is put into proof-reading block 7 in the reference block 2 earlier, and dial gauge 5 is proofreaded zero line, takes out proof-reading block 7 then, tested part 1 is put into positioning core axle 6 detect, and this moment, dial gauge 5 readings were B.
Method of the present invention is to calculate angle with the difference in height on two different-diameters on the same center of circle, the diameter of getting basic circle 10 is D, cone diameter maximum circle is basic circle; the diameter of getting measured circle 9 is d; the minimum place of cone diameter circle is measured circle; the difference in height of two circles is L+B, according to Gong Shi ﹠amp;=2arctg (D-d)/2 (L+B) just can obtain Jiao ﹠amp; Value.
Explanation is at last; above embodiment only is used to illustrate technical scheme of the present invention and is unrestricted; other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement; only otherwise break away from the spirit and scope of technical solution of the present invention, all should cover in the protection claimed range of the present invention.
