Description

Be used to measure the clinometer rule of corner between two rotary bodies

Technical field

The utility model relates to the clinometer rule that a kind of field of engineering technology is used to measure corner between two rotary bodies.

Background technology

When structural design, the relative angle when regular meeting needs the measuring system running between the turning axle.General commonly used method is to adopt rotary encoder or angle measurement scrambler to finish the measurement of relative angle, uses often in reality the stator of scrambler and rotor to be separately fixed in relative rotation on two parts, and makes their axis pass through rotation.This method is simple and convenient, and the output angle of scrambler is exactly the actual angle of two rotating parts.But because the overall objective restriction, the axial space of system is often very limited, and clinometer rule can't be arranged on the rotation, and existing method and apparatus can't be used, and brings a difficult problem for construction or design.

The utility model content

At the problems referred to above, task of the present utility model provides the clinometer rule that a kind of field of engineering technology is used to measure corner between two rotary bodies, only converts by simple proportional, just can get the angle between the turning axle in the shaft system.

For finishing above-mentioned task, the technical solution of the utility model has been to provide a kind of clinometer rule that is used to measure corner between two rotary bodies, this clinometer rule is counted the master by an accurate rotary current potential and is constituted, potentiometric rotating shaft side body bottom is provided with mount pad, is equipped with in the potentiometric rotating shaft and radially puts handle.

Described pendulum handle is a V shape pendulum handle.

Slidable fit has slide block in the handle fork of described V shape pendulum handle, and slide block is provided with an axial balance staff.

Described pendulum handle is a slide bar type pendulum handle, and slip cap is equipped with a slide block on the slide bar type pendulum handle, and slide block is provided with an axial balance staff.

This programme is installed in well-to-do relatively position, space in the system with clinometer rule, and it is flexible to have an installation site, the angle easy characteristics that convert.Through application verification, respond well, not only accurately angle measurement, and the overall dimensions of having dwindled system are fully used the useful space.The utility model structurally is easy to realize, need not complicated parts or mechanism; Survey angle and need angle measurement degree conversion relation simple; Can flexible arrangement in structure, can effectively utilize the remaining space of system.

Concrete real-time mode

As shown in Figure 1 and Figure 2, when we need measure between the rotational parts 1,2 relative rotation around rotation.Select for use precision potentiometer as clinometer rule, pot is fixedlyed connected with rotational parts 1, and slide block is fixedlyed connected with rotational parts 2, and the fork-shaped part is connected on the potentiometric angle measurement axle by holding screw, and slide block can slide in the chute of fork-shaped part.

In the actual motion process, the actual measurement angle that pot is directly measured is the relative rotation α between fork-shaped part and the rotational parts 1, and the corner β between the rotational parts 1,2 can draw by simple trigonometric function relation.In design process, suppose that the distance between rotation and the precision potentiometer rotating shaft is a, the distance between rotation and slide block center line or the balance staff is b, then the angle of asking and the relation of actual measurement between the angle suc as formula 1:

$\sin (\mathrm{\α}-\mathrm{\β})=\frac{a}{b}\sin \mathrm{\α}---\left(1\right)$

By calculating, can get the corner β between two rotary bodies.
