Abstract

The present invention relates to a cone-surface measuring tool for the rotor of a large motor. According to the technical scheme of the measuring tool, a positioning disc (3) is tightened onto the end surface of a rotor via a locking screw (4). An extension rod (1) is tightened onto the positioning disc via a screw (2). The angle alpha of a cone surface, the diameter d3 of a small end and the diameter d of a ball-head micrometer are defined in a drawing. Based on the above requirements of the drawing, to-be-measured dimensions d1 and d2, and a tolerance can be calculated. During the fine grinding process of the cone surface, only the to-be-measured dimensions d1 and d2 are machined to be within the tolerance range of the dimensions d1 and d2 that are calculated according to a formula. The measuring tool is used for measuring the cone surface of the rotor of a large motor. By means of the measuring tool, the difficult problem that the cone surfaces of the rotor shafts of large motors are difficult to measure during the fine grinding process can be solved. Meanwhile, the measuring tool is more accurate in measurement and the dimensions of cone surfaces can be measured more quickly. Moreover, the measuring tool is high in accuracy.

Description

Large Rotor conical surface survey instrument
Technical field: the present invention relates to a kind of Large Rotor conical surface survey instrument.
Background technology: in the accurately machined process of nuclear power three generation products rotor, need the Precise Grinding conical surface, this just needs to measure the conical surface accurately, because the diameter of axle is large, measures with corresponding ring gauge, and weight is large, use is inconvenient, can not measure numerical value accurately.
Summary of the invention: the object of this invention is to provide a kind of survey instrument can measuring conical surface size fast, accurately.Technical scheme of the present invention is: a kind of Large Rotor conical surface survey instrument, it is characterized in that: positioning disk (3) by lock-screw (4) tight on the end face of rotor (5), the inclined-plane of two extension rods (1) is attached on the conical surface of rotor, one end of two extension rods (1) abuts on the end face of positioning disk (3), two extension rods (1), through the waist hole of positioning disk (3), are fixed on the end face of positioning disk (3) by two screws (2) respectively.
Its principle of work of the present invention is: positioning disk (3) by lock-screw (4) tight on the end face of rotor, extension rod (1) by screw (2) tight on positioning disk, as shown in Figure 2, according to frustoconical bevel angle α, the end diameter d3 of drawing requirement, the diameter d of bulb milscale, calculate required d1, d2 of measuring:
d 1 = 2 L tan α 2 + d 2
d 2 = d 3 + d tan ( 45 + α 4 ) - d
During the fine grinding conical surface, only need the value of d1, d2 of measurement to be milled in corresponding tolerance, just can make frustoconical bevel angle α, end diameter d3 is machined to required size.
Advantage of the present invention and other similar means contrast and have the following advantages:
Measured the Large Rotor conical surface to need to test color method measurement with ring gauge in the past, and during inspection tapering, needed the rotor conical surface and ring gauge inner conical surface are fitted tightly, rotate the angle that ring gauge is certain.Because the root diameter of large-size machine is larger, corresponding measurement ring gauge weight is large, operating difficulties, and the numerical value can not measuring actual tapering.When using the present invention to measure the Large Rotor conical surface, by positioning disk (3) by lock-screw (4) tight on the end face of rotor (5), the inclined-plane of two extension rods (1) is attached on the conical surface of rotor, one end of two extension rods (1) abuts on the end face of positioning disk (3), two screws (2) are through the waist hole of positioning disk (3), after on the end face respectively two extension rods (1) being fixed on positioning disk (3), only need with the d1 in bulb miking Fig. 2, d2, can accurately calculate tapering actual value like this, and weight ratio of the present invention is lighter, structure is simple, easy to use, can be quick, measure conical surface size accurately.
Accompanying drawing explanation
Fig. 1 is that view installed by Large Rotor conical surface survey instrument
Fig. 2 is that view measured by Large Rotor conical surface survey instrument
Embodiment
A kind of Large Rotor conical surface survey instrument as shown in Figure 1, positioning disk 3 by lock-screw 4 tight on the end face of rotor 5, the inclined-plane of two extension rods 1 is attached on the conical surface of rotor, one end of two extension rods 1 abuts on the end face of positioning disk 3, two extension rods 1, through the waist hole of positioning disk 3, are fixed on the end face of positioning disk 3 by two screws 2 respectively.
As shown in Figure 2, according to the length L of extension rod 1, conical surface α to be processed, the diameter d 3 of rotor small end to be processed and the diameter d of bulb milscale, calculate required d1, d2 size measured:
d 1 = 2 L tan α 2 + d 2
d 2 = d 3 + d tan ( 45 + α 4 ) - d .
During the fine grinding conical surface, measure the numerical value of d1, d2, need the value of d1, d2 of measurement fine grinding in the tolerance of the size d1 utilizing formulae discovery to go out, d2.
