Cheng Zhongyou strong actual demand.
There are mainly two types of detection modes for end face bulge quantity at present:
(1) platform+auxiliary detection tool: placing dedicated adjustable auxiliary detection tool in detection platform, and tappet is placed in auxiliary
In cubing, by altitude meter and adjustment auxiliary detection tool, the smoothing of 3 points of tappet top surface measures highest point to basic circle using altitude meter
Difference in height, as bulge quantity；
(2) three coordinates: measuring basis circle is used as reference projection plane by drawing, to end face center multimetering, meter
The distance that point arrives face is calculated, is maximized as bulge quantity.
Existing detection mode is primarily present following defect:
(1) it can not achieve on-line checking: being line external pelivimetry, cannot achieve instant, live, quick detection, this is very
It is unfavorable for process control when continuous production；
(2) measurement efficiency is low: time of measuring is long, and measurement process is complicated, cumbersome.Detection of platform mode, knack worker
5 ~ 8 minutes/part is needed, three coordinate measurements are averaged 2 ~ 3 minutes/part after completing adjustment；
(3) measurement stability is poor: the measurement accuracy of detection of platform is due to by platform precision, the technical ability of plane adjustment, mesh
Survey highest point position inaccuracy and basic circle smoothing etc. multiple links influence, measurement accuracy is not high, stability is poor, three coordinates by
In there are the influence of reference projection plane error, measurement accuracy is not equally high；
(4) measurement cost is big: detection of platform, the investment of three coordinate measurements is larger, detection place needs occupancy is a large amount of empty
Between, while needing to be equipped with professional testing staff.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of portable survey of end face bulge quantity
Measure device, can easily and fast, high-precision measurement tappet end face bulge quantity.
According to technical solution provided by the utility model, a kind of end face bulge quantity Portable type measurement unit, it is characterized in that: packet

Head is exposed by the lower section of through-hole；Positioning thread insert is installed in the inspection specific bottom, positioning thread insert central through hole region be used as to
Survey the measurement and positioning hole of workpiece, the positioning thread insert and the specific central coaxial line of inspection.
Further, the cubing body is made of steel.
Further, notching construction is set in the inspection specific upper end, notching construction is connected to through-hole, in notching construction
Outside be arranged taper thread, notching construction outside setting locking flare nut, locking flare nut by taper thread and fluting knot
Structure locks amesdial.
Further, external screw thread is set in the inspection specific bottom, and positioning thread insert is installed by the external screw thread.
Further, the measurement and positioning hole of cubing body bottom is rectangular or round.
The utility model has the advantage that
(1) the utility model realizes the portable type measuring of shaft forgings end face bulge quantity, can production process scene, at
Product go out the scene of being put in storage and realize measurement；
(2) measurement accuracy can satisfy design accuracy (usual tappet end face bulge quantity accuracy tolerance be the μ of 10 μ ~ 15, through trying
Test to ratio error≤2 μ, fully meet measurement accuracy requirement), it is higher than detection of platform (precision≤4 μ) and three coordinate measurement (precision
≤ 3 μ)；
(3) with regard to the measurement of tappet end face bulge quantity, beat≤10 second/part is measured, efficiency is the 12 of three coordinate measuring machine
Times or more, 30 times or more of detection of platform；
(4) compared with three coordinate measuring machine, the cost of investment of the measuring device is small.
