Description

Measured material

Technical field

The utility model relates to a kind of measured material, is applicable to general small-sized shaft element, both can measure material object separately, can measure subassembly again, can extensively use in field of machining and machinebuilding technology.

Background technology

Original measured material is single three-phase axle (axial workpiece) to be measured, and cubing is simple in structure, and precision is low, accuracy rate is not high, and error is arranged during judgement, can only detect the right alignment technical indicator, do not have the guide rail move mode, can not carry out multimetering, the data of therefore judging are not comprehensive.It also is one pair of simple measured material that rotating disk is measured, and its measuring accuracy simple in structure is low, can only measure the radial beat eccentricity of rotating disk.In a word, this mode is simple in structure, and degree of accuracy is low, measures purposes not extensive, and measurement data can not reflect True Data in kind all sidedly.

The utility model content

The purpose of this utility model is exactly in order to address the above problem, and a kind of measured material is provided.

To achieve these goals, the utility model adopts following technical scheme:

A kind of measured material that is applicable to the small shafts parts and not only can have measured material object separately but also can measure subassembly is characterized in that having:

The support (1) that contains one to be detected mounting groove, its bottom is equipped with base plate;

Be located at the slide block (3) of mounting groove, it is equipped with gear shaft (2), and described slide block is provided with the gear that cooperates with gear shaft;

Be installed on respectively the bearing seat combination (4) at the place, mounting groove two side of support, it comprises bearing seat, is located at precise rolling bearing and the axle sleeve combination of bearing seat, the precise rolling bearing of described bearing seat is equipped with thimble axle (5), and two are installed on the thimble axle coaxial arrangement of precise rolling bearing;

The rack combination that is installed on base plate and is connected with slide block, it comprises tooth bar seat and the tooth bar of being located at the tooth bar seat.

The beneficial effects of the utility model are: compact conformation, degree of accuracy are higher, easy to operate when measuring, the utilization scope is wide, can measure multiple spot and the measured material of composite measurement ability is arranged.
