Abstract
The utility model discloses a kind of centre bore rapid survey tools, including measurement tool and fixing sleeve, the measuring mechanism is made of sequentially connected amesdial, connecting shaft, depth rod and probe, depth rod outer wall forms the sliding slot and scale being arranged along axis, fixing sleeve hole wall forms the threaded hole being disposed radially, lock screw is threaded into hole, and fixing sleeve and depth rod are fastened.The utility model provides a kind of centre bore rapid survey tool, it is mainly used in process, workpiece small hole concentricity can be detected, whether and it is qualified fast and accurately to measure workpiece small hole depth, avoid the generation of substandard product, doing over again for workpiece is greatly reduced, efficiency when more bit change is improved.
Description
Technical field
The utility model belongs to a kind of hole measurement device, and in particular to a kind of centre bore rapid survey tool.
Background technique
Currently, easily being trained off since workpiece small hole aperture is too small, and naked eyes can not identify, there is no measurable tool, often result in
Because discovery aperture trains off and makes postorder that can not process waste not in time, and continuously generates waste product situation.
Small hole depth is fast and accurately measured at scene without measurer, if there is dimensional problem that cannot find in time, is often occurred big
Measure repair conditions of doing over again.And in more bit change can only by the way that repeatedly the method for test run reaches size repeatedly, when due to test run,
Workpiece need to be removed from fixture, see whether to get through, however repeatedly cutting repeatedly, the significant wastage working time, vehicle repeatedly
It cuts repeatedly, increases mismachining tolerance, easily cause orifice size unqualified, to cause to scrap.
Utility model content
The utility model is proposed to overcome disadvantage existing in the prior art, and the purpose is to provide a kind of center
Hole rapid survey tool.
The technical solution of the utility model is:
A kind of centre bore rapid survey tool, including measurement tool and fixing sleeve, the measuring mechanism is by sequentially connected thousand points
Table, connecting shaft, depth rod and probe composition, depth rod outer wall form the sliding slot and scale being arranged along axis, fixing sleeve hole wall shape
The threaded hole being radially arranged, lock screw is threaded into hole, and fixing sleeve and depth rod are fastened.
The amesdial, connecting shaft, depth rod and probe coaxial line.
It is zero graduation among the scale.
Where the fixing sleeve is sheathed on centre bore on the outside of axis.
Clearance fit between the through-hole and depth rod of the fixing sleeve.
The fixing sleeve top surface is concordant with center hole end surface.
The lock screw tail end protrudes into sliding slot.
The beneficial effects of the utility model are:
The utility model provides a kind of centre bore rapid survey tool, is mainly used in process, can be small to workpiece
Hole concentricity is detected, and can fast and accurately measure whether small hole depth is qualified, avoids the production of substandard product
It is raw, doing over again for workpiece is greatly reduced, efficiency when more bit change is improved.

Specific embodiment
With reference to the accompanying drawings of the specification and embodiment carries out specifically a kind of centre bore rapid survey of the utility model tool
It is bright:
As shown in Fig. 1 ~ 5, a kind of centre bore rapid survey tool, including measurement tool 1 and fixing sleeve 2, the measuring mechanism by
Sequentially connected amesdial 3, connecting shaft 4, depth rod 5 and probe 6 form, and 5 outer wall of depth rod forms the sliding slot 7 being arranged along axis
With scale 8,2 hole wall of fixing sleeve forms the threaded hole that is disposed radially, and lock screw 10 is threaded into hole, and by 2 He of fixing sleeve
Depth rod 5 fastens.
The amesdial 3,6 coaxial line of connecting shaft 4, depth rod 5 and probe.
It is zero graduation among the scale 8.
Where the fixing sleeve 2 is sheathed on centre bore on the outside of axis.
Clearance fit between the through-hole 9 and depth rod 5 of the fixing sleeve 2.
2 top surface of fixing sleeve is concordant with center hole end surface.
10 tail end of lock screw protrudes into sliding slot 7.
The measurement method of the utility model:
Before measurement, hard alloy steel planar surface is cleaned out, measured workpiece is then put in planar surface；Measurement
The preceding cooperation precision for first calibrating fixing sleeve and depth rod, and check for corrosion or foul.
When measurement, measured workpiece is put in planar surface, fixed measurer set is inserted at the measured workpiece shaft shoulder, it is ensured that
Be installed in place, depth dose rod set then entered into fixed measurer set, it is to be installed in place after, pass through the label ruler on depth dose club body
Little progress row reading, if there is deviation, can adjust cutter compensation according to measured value to obtain the small hole depth of surveyed workpiece.If
The smooth insertion rod set standard depth position of gauge rod illustrates that aperture is qualified and concentricity depth reaches standard.
Judge using whether the probe of measurement tool is up to standard to aperture, when aperture qualification, pointer is located at 0, works as finger
Just when deviating, illustrate that aperture is unqualified, when hole trains off, when deviant is within 0.1MM, hole is in next sequence can be with
It is modified, beyond can only then scrap.
Depth interpretation is determined by the scale in depth rod, when " 0 " scale on fixing sleeve top surface and depth rod is flat
Qi Shi, depth are qualified；When fixing sleeve top surface is concordant with probe side scale close in depth rod, illustrates that hole depth is spent shallowly, need
It is further processed；When fixing sleeve top surface is concordant with amesdial side scale close in depth rod, illustrate that hole depth is too deep, no
Qualification is scrapped.
Lock screw design, is fixed, convenient reading numerical value convenient for fixing sleeve and depth rod, and reading will not change when removing measurer
Become.
The utility model, which can satisfy, to be quickly detected aperture concentricity in time and accurately measures in process
Small hole depth avoids the generation of rejected product, reduces doing over again for workpiece, replacement drill bit efficiency is improved, to reach raising work
The effect of efficiency and product qualification rate.
