Abstract

The utility model discloses a mechanical type automatic roundness measuring mechanism, comprising an identity, a rubbing pair, a pressing spring and an end cap. The identity is a cavity with one end connecting with the end cap while the other end externally connecting with an amesdial which is arranged in the body cavity of the identity and contacts with the rubbing pair. The rubbing pair is arranged in the cavity of the identity and floats in the identity via the pressing spring with the end drilling through the end cap, and the top end is press fitted with an alloy feeler pin. The pressing spring is coated on the transition piece of the inner wall of the identity with impaction. The alignment pin is arranged in the spacing slot of the rubbing pair by crossing the long-middle bore of the transition piece and can generate the axial relative slipping with the rubbing pair. The measuring mechanism reduces the uncertain element factor brought artificially, which efficiently improves the measuring accuracy and efficiency, in particular suitable for the direct roundness measuring of the surface of the machine part in large batch.

Description

The automatic roundness measurement of mechanical type mechanism
Technical field: the utility model belongs to the mechanical measurement technique field, relates to the automatic roundness measurement of a kind of mechanical type mechanism.
Background technology: for a long time, in general piece surface precision measure index, jitter values is that the difference of peak and minimum point is usually as an important indicator weighing accuracy class.Circle diameter run-out value is a kind of in the surperficial jitter values classification, and purposes is very extensive, in the operation of reality, major part be with machinery thousand (hundred) submeters as instrument, add mental arithmetic based on artificial interpretation; The existence that owing to the people is the uncertain factor brought causes measuring accuracy not high, and efficiency of measurement is also lower simultaneously.
Summary of the invention: the low problem of measuring accuracy, efficiency of measurement that the utility model causes for the artificial uncertain factor that solves existing roundness measurement instrument existence, propose the automatic roundness measurement of a kind of mechanical type mechanism, it is characterized in that: described measuring head comprises body, friction pair, stage clip, end cap; Described body is a cavity, a termination end cap, and the external clock gauge of the other end, described clock gauge gauge head are positioned at described body cavity and contact with described friction pair; Described friction pair is positioned at the cavity of described body, floats in the described body by described stage clip, and described end cap is passed in the end, and the top is pressed with gauge head; Described stage clip by described friction pair clamping sleeve on the spacer shell of described inner body wall; The long lumbar hole that described register pin passes described spacer shell is arranged in the stopper slot of described friction pair, and can produce axially relative slippage with described friction pair.
It is the uncertain factor of bringing that the automatic roundness measurement of this mechanical type mechanism has reduced the people, has improved measuring accuracy and efficiency of measurement effectively, is particularly suitable for the direct measurement on surfaces such as machinery part surface circularity in enormous quantities.
Description of drawings: Fig. 1 is the structural representation of the automatic roundness measurement of the utility model mechanical type mechanism;
Fig. 2 is the automatic roundness measurement of a utility model mechanical type mechanism friction pair structural representation front view;
Fig. 3 is the automatic roundness measurement of a utility model mechanical type mechanism friction pair structural representation vertical view.
Embodiment: as shown in Figure 1, the automatic roundness measurement of this mechanical type mechanism comprises measuring head body 4, friction pair 14, end cap 11, stage clip 8; Wherein body 4 is a cavity, the external clock gauge 1 of an end, and clock gauge 1 is fixed on the body 4 by jackscrew 3 and fixing spring cover 2, and the clock gauge gauge head is positioned at body 4 cavitys and contacts with friction pair 14; Body 4 other ends are threaded with end cap 11; Friction pair 14 is positioned at the cavity of body 4, and is coaxial with the measuring staff of clock gauge 1, and friction pair 14 is made up of overcoat 9 and interior axle 10, floats in the body 4 by stage clip 8, and end cap 11 is passed in the end of interior axle 10, and the top is pressed with alloy gauge head 12; Stage clip 8 is pressed on the spacer shell 7 by the shaft shoulder 13 of axle 10 in the friction pair, and spacer shell 7 is enclosed within the inwall of body 4; Location stop pin 6 is fixed on the measuring head body 4, and the long lumbar hole 16 that the other end passes spacer shell 7 is arranged in the stopper slot 15 of friction pair overcoat 9, and can produce axially relative slippage with overcoat 9.
Return zero accurately for what guarantee clock gauge 1, improve measuring accuracy, the end face that contact with body 4 at friction pair overcoat 9 is provided with location bulb 5, changes a face contact into by the contact of face face, thus guaranteed time zero accurate.Friction pair can adopt multiple structure, when adopting telescopic friction pair, as Fig. 2, shown in Figure 3, on friction pair overcoat 9, leave slit 17 with wire cutting method vertically, can be one or more of, purpose be under the effect of internal stress, makes overcoat 9 produce inside radical elasticity; Radially offer elongated slot 18 again, elongated slot 18 is no more than the axial length of slit 17, its objective is in order to adjusting elastic force, and then reaches the purpose of regulating friction force.
Its know-why is to utilize the equilibrium relation of the accurate control survey power of friction pair and spring force, gravity etc., alloy gauge head by rigidity contacts and passes to this measuring mechanism with piece surface, measuring head is found out " peak " on surface automatically in the first lap of part rotation, relative " highly " of each point can be delivered to instrument in the rotation afterwards and show.Promptly be to utilize friction pair to seek " peak " automatically, and be defined as zero automatically, simultaneously jitter values is directly passed to corresponding instrument, need not manually calculate, directly show the circle jitter values.This measuring mechanism can improve measuring accuracy, efficiency of measurement effectively, and having reduced the people is the uncertain factor of bringing, and cost is very cheap, is suitable for the direct measurement on surfaces such as machinery part surface circularity in enormous quantities most.
