Description

A kind of device for detecting length of repacking measurement equipment axis

Technical field

The utility model belongs to field of measuring technique, is related to a kind of device for detecting length of repacking measurement equipment axis.

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 is not reached to requirement eliminates.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 and depth of two segment length and Inner holes to axle detect.Currently without special equipment automatically to the axle of this structure Detected, the detection for this kind of axle is mainly carried out by way of manually using instrumentation detection, this kind of method efficiency It is relatively low, and easily there is mistake in artificial detection.

The content of the invention

The purpose of this utility model is above mentioned problem be present for existing technology, it is proposed that a kind of repacking measurement equipment axis Device for detecting length, the utility model solve technical problem be that can accurately measure the length of axle.

The purpose of this utility model can be realized by following technical proposal：

A kind of device for detecting length of repacking measurement equipment axis, repacking measurement equipment include workbench and set on the table Test desk, it is characterised in that the device for detecting length of this axle includes upper range sensor, lower range sensor and is fixed on survey The detection pedestal on platform is measured, the detection pedestal includes bearing block, the shaft core being rotatably connected in detection pedestal and consolidated with shaft core Surely there is the benchmark panel on benchmark convex surface, the shaft core is vertically arranged and shaft core has the upper through hole for being available for axle to penetrate, the base Quasi- panel is fixed on the upper end of shaft core, and the test desk is provided with the rotational structure for driving the shaft core in detection pedestal to rotate, institute Range sensor is stated to be fixed on test desk and be fixed on test desk positioned at the surface of shaft core, the lower range sensor And positioned at the underface of shaft core.

In detection, the upper through hole of the less one section of insertion shaft core of shaft diameter, the step of axle and shaft core are against causing axle to erect Straight to set, upper range sensor and lower range sensor contact with the upper surface of axle and lower surface respectively, due to upper Distance-sensing Position between device, lower range sensor and benchmark convex surface determines, therefore it is larger by upper range sensor to detect shaft diameter One section of length, the length of smaller one section of shaft diameter can be detected by lower range sensor；Pass through rotational structure band in detection Moving axis core rotates, thus axle also can be with rotation, therefore upper range sensor can contact with the upper surface diverse location of axle respectively, Lower range sensor can be contacted with the lower surface diverse location of axle respectively, and shaft diameter can be accurately obtained by the measurement of multiple positions Larger one section and the length of smaller one section of diameter；Preferably, the upper range sensor and lower range sensor in the application are adopted It is existing product with model GT2-A50 sensor.

In the device for detecting length of above-mentioned repacking measurement equipment axis, the rotational structure includes motor, belt Wheel shaft, the upper bearing (metal) and lower bearing being rotatably connected in bearing block, the shaft core plugged and fixed is in upper bearing (metal), the belt pulley Axle plugged and fixed has resigning gap one, the Pulley shaft in the inner ring of lower bearing between the shaft core and Pulley shaft Positioned in the circumferential with shaft core and the relative shaft core of Pulley shaft energy is axially moveable, the lower end of the Pulley shaft passes bearing block And driven pulley is fixedly connected with, the lower surface of the driven pulley and bearing block has resigning gap two, the driving Motor is fixed on test desk, is fixed with drive pulley in the rotating shaft of the motor, the drive pulley and driven Connected between belt pulley by the belt of tensioning.In detection, the lower end of axle is located at shaft core and the step surface of axle supports with shaft core By positioning, shaft core and Pulley shaft be rotatably connected in bearing block by upper bearing (metal) and lower bearing respectively, both and bearing block it Between attachment structure it is separate, shaft core and Pulley shaft only position in the circumferential, belt drive driven pulley rotate when Situation about fluctuating occurs, driven pulley can fluctuate with Pulley shaft, and resigning gap one causes Pulley shaft There is the space fluctuated between shaft core, resigning gap two, which to have between driven pulley and bearing block, fluctuates Space, and because shaft core is not connected to Pulley shaft in the axial direction, therefore dynamic belt pulley and Pulley shaft fluctuate not The vibration or movement of shaft core either bearing block can be caused, axle to be detected in shaft core is positioned at and is unaffected, therefore energy Ensure the precision and accuracy of shaft detection；Rotated by a root skin band with several driven pulleies, multiple detections can be realized Pedestal synchronously detects, and compact-sized and detection efficiency is higher.
