Abstract

The utility model relates to an electronic digital display measurer which can measure the deviating degree of a certain point on an object surface with different radian (including zero radian plane) from the normal radian of the object surface. The utility model is composed of a fixed support, a sliding support, a measuring probe and an electron displacement checking meter. After the normal surface reference radian of a measured object is confirmed by two points on the fixed support and one point on the sliding support, the convex-concave value of the measured point deviating from the normal reference radian is read out on the electron displacement checking meter by moving the determine to contact the measured position.

Description

Body surface convex-concave degree measurement instrument

Affiliated technical field

The utility model relates to a kind of surveying instrument of body surface convex-concave degree; can measure a certain position on the different radians body surface of (comprising 0 radian plane) and depart from the convex-concave degree of the normal radian of this body surface; can read the concrete convex-concave value that departs from by the electronic digit display screen on the measuring instrument, measuring accuracy is 0.01mm.

Background technology

At present, Measuring Object surface convex-concave degree methods has a lot, and instrument also has a variety of, but all be to want to measure accurate method mostly with regard to more complicated, it is just bigger to want the simple error of measuring method, and the instrument price is all higher accurately mostly, is difficult for being applied in the routine work.Therefore, lack that a method is simple, low price, data surveying instrument accurately.

Summary of the invention

In order to solve measuring method, instrument price and order of accuarcy three's contradiction, the utility model provides a kind of measuring instrument, and this measuring instrument not only cost is low, importantly is simple and easy to usefulness, be easy to carry, and measurement result is accurate.Use this measuring instrument can measure different radian body surfaces (sphere, concave surface, plane) go up certain position with respect to this body surface normally with reference to the convex-concave value of radian, directly by the display screen reading of data.

The technical scheme that its technical matters that solves the utility model adopts is: establish two contacts on fixed support, establish a contact on sliding support, add the measuring probe needle point, be provided with four metering contacts that distance is impartial altogether.During measurement, after a reference surface (cambered surface or plane) has been determined in three contacts on fixed support and the sliding support, promote measuring probe and be close to tested position, if the reading of electron displacement detector is 0, illustrate that tested position and reference surface are on same cambered surface or the plane, if the reading of electric electron displacement detector has positive and negative branch, positive number is represented the measured point than the degree of protruding with reference to radian, and negative number representation measured point ratio is with reference to the recessed degree of radian.The measuring accuracy of this body surface convex-concave degree measurement instrument is relevant with the precision of the electron displacement detector that is adopted, and can be as accurate as 0.01mm.

The beneficial effects of the utility model are: simple, quick in certain some convex-concave degree of Measuring Object surface, accurately.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is a unitary construction front view of the present utility model.

Among the figure: 1. fixed support, 2. sliding support, 3. measuring probe, 4. electron displacement detector, 5. metering contact, 6. metering contact, 7. metering contact, 8. metering contact.

Embodiment

In the accompanying drawings, sliding support (2) is installed on the fixed support (1), and can slide up and down by relative fixed support (1); Electron displacement detector (4) is fixed on the sliding support (2), can not move; Measuring probe (3) is installed on the electron displacement detector (4), and electron displacement detector (4) slides up and down relatively, and its slippage can show on the screen of electron displacement detector.The four measuring contact (5) (6) (7) (8) of this body surface convex-concave degree measurement instrument is in same straight line when original state, and distance is impartial, utilize 4 move mutually can convex surface, concave surface and the plane of Measuring Object on certain part protrude or recessed degree with respect to normal surface.The size dimension of measuring instrument and measurement range can be decided according to the needs of practical application area.

Claims

1. body surface convex-concave degree measurement instrument, form by fixed support, sliding support, measuring probe and electron displacement detector four parts, on fixed support, be provided with two contacts, a contact is set on sliding support, add that measuring probe is provided with four metering contacts that distance is impartial altogether, it is characterized in that: three contacts on fixed support and the sliding support determined one with reference to cambered surface or plane after, contact tested position with measuring probe, on the electron displacement detector, read measurement result.
