Description
Technical field
The invention belongs to field of measuring technique, it is related to the detection dress of a kind of repacking measurement equipment axis length and hole size
Put.
Background technology
In high precision apparatus field to equipment in the sizes of parts require higher, therefore after parts complete
It will be detected, the defect ware that size does not reach requirement is eliminated.There is a kind of axle at present, axle has diameter different
Two sections, form step between different two sections of diameter, the end that less one section of shaft diameter is provided with Inner holes, needed before assembly
The diameter of two segment length and Inner holes to axle is detected.Examined currently without the automatic axle to this structure of special equipment
Survey, the detection for this kind of axle is mainly carried out by way of manually being detected using instrumentation, and this kind of method is less efficient, and
Easily there is mistake in artificial detection.
The content of the invention
The purpose of the present invention is there is above mentioned problem for existing technology, it is proposed that a kind of repacking measurement equipment axis length
And the detection means of hole size, present invention solves the technical problem that being that the length and its endoporus of axle accurately can be measured.
The purpose of the present invention can be realized by following technical proposal：
A kind of detection means of repacking measurement equipment axis length and hole size, repacking measurement equipment includes workbench and setting
Test desk on the table, it is characterised in that the detection means of this shaft length and hole size includes detection air pump, airtight survey
Amount instrument, upper range sensor, lower range sensor and be arranged on test desk three detection pedestals, three detection pedestals according to
The shaft core for locating shaft is provided with secondary arrangement, the detection pedestal, the shaft core of three detection pedestals can be tied by rotating
Structure synchronous axial system, the workbench, which is provided with, to shift station that axle be moved to another detection pedestal from a detection pedestal
Device, the upper range sensor and lower range sensor are fixed on the table and consistency from top to bottom, one of detection pedestal
Crane is additionally provided with the position that can be moved between upper range sensor and lower range sensor, the workbench, institute
State and two plug jets set straight up are fixed with crane, two other detection pedestal can be moved to two gas
Move the surface of gauge head and two aerodynamic sides heads can be just right with two shaft cores detected in pedestals respectively, the detection air pump
It is connected with airtight measuring instrument by tracheae, the airtight measuring instrument is connected with two plug jets respectively by tracheae.
Upper range sensor and lower range sensor are contacted with the upper surface and lower surface of axle respectively, due to upper Distance-sensing
Position between device, lower range sensor and shaft core is determined, therefore can detect larger one section of shaft diameter by upper range sensor
Length, the length of smaller one section of shaft diameter can be detected by lower range sensor；Pass through rotational structure band moving axis in detection
Core is rotated, thus axle also can be with rotation, therefore upper range sensor can be contacted with the upper surface diverse location of axle respectively, under away from
It can be contacted respectively with the lower surface diverse location of axle from sensor, it is larger to be accurately obtained shaft diameter by the measurement of multiple positions
One section and the length of smaller one section of diameter；By crane so that aerodynamic side head rises and penetrated in the endoporus of axle, at the same time
Air-pump inflating is detected, air-flow by plug jet by entering endoporus again after airtight measuring instrument；Because plug jet penetrates axle
Be not necessarily located at during endoporus on the axis of axle, thus by detection rotary shaft cause the inwall of axle endoporus and aerodynamic side head
Between dynamic change, airtight measuring instrument can detect the pressure change from plug jet eluting gas, and send data to computer
Upper to be compared with pre-stored values, the hole size of axle, which is met, if data are in the range of pre-stored values requires, if data exist
Then the hole size of axle is unqualified outside the scope of pre-stored values, carries out repeated detection to the endoporus of axle by two groups of detection pedestals, protects
Demonstrate,prove the precision of detection.
