Description
Technical field
The utility model relates to a kind of novel dial gauge fixed mechanisms.
Background technique
The main technical requirements of shaft coupling assembly are to guarantee the concentricity of two axial lines.Excessive coaxiality error will make shaft coupling
Device, transmission shaft and its bearing generate additional load, and result can cause the vibration of machine, the premature abrasion of bearing, mechanical seal
Failure, or even fatigue fracture accident, therefore, measurement method accurate and reliable distich more demanding to shaft coupling accuracy of alignment occurs
Axis device accuracy of alignment influences very big.Measurement method substantially ruler feeler gauge method, outer circle and end face double meter method, outer circle and end face at present
The modes such as genuine standard, through frequently with outer circle, the double dial gauge methods in end face, dial gauge fixing seat is using magnetic table in terms of precise measurement
Seat, by magnetic absorption in steel surface, shaft one is fixed on Magnetic gauge stand, the fixed dial gauge in other end, and dial gauge is logical
Shaft adjustment shaft coupling outer circle or end face upright position are crossed, to measure, the dial gauge fixed form and measurement operation letter
It is single, good application effect, high reliablity.
But due to measurement when dial gauge be all to be fixed on axis or shaft coupling by shaft and Magnetic gauge stand, exist with
The problem of lower two aspects: 1, requiring the rotary space of rectification measuring mechanism, and in open space, then there is no problem, but
It is the clutch space in relative narrowness, then dial gauge fixed frame can not be fixed, fixed frame or magnet base frequent scraping collision when revolution
It falls off, the working condition of measurement request is not achieved；2, under normal circumstances, shaft coupling material is iron, cobalt, nickel and its alloy and iron oxygen
Body casts material or steel, can be adsorbed by Magnetic gauge stand, but some weak magnetic shaft coupling materials, not such as copper, aluminium and some austenites
Become rusty steel, cannot be adsorbed.
Therefore, the prior art could be improved.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of novel dial gauge fixed mechanism, guarantee in use hundred
Point table can be fixed quickly well, avoid because dial gauge measurement is limited or can not carry out caused by fixed form is bad.
To achieve the above object, the technical solution of the utility model is:
A kind of novel dial gauge fixed mechanism, for positioning of the dial gauge on shaft coupling, shaft coupling reference edge is equipped with axis
To pin hole, the dial gauge fixed mechanism includes expansion set, connector, backing plate, connecting rod, pole band and shaft, and expansion set is arranged
In pin hole, backing plate is fixed on the end face of shaft coupling reference edge by expansion set and connector, and the vertical shaft coupling of connecting rod is axially set
It sets, one end is fixed on backing plate, and the other end is connected by one end of pole band and shaft, and dial gauge is fixed on the other end of shaft.
As a kind of improvement of the utility model, the expansion set includes the inner ring of cylindrical outer ring and cone, outside
Enclosing has the inner conical surface to match with inner ring male cone (strobilus masculinus), and outer ring and inner ring all have axial notch, and the connector includes
Bolt and wing nut, bolt are spirally connected after passing through inner ring, outer ring, backing plate with wing nut.
The utility model compared with prior art, the beneficial effect is that:
1, the swelling by expansion set in measuring piece axis hole makes dial indicator holder in non-magnetic material to replace Magnetic gauge stand
It is reliably fixed on shaft coupling.
2, dial indicator holder and shaft coupling closely connect, avoid the absorption of former Magnetic gauge stand bad and caused by measure distortion.
3, according to shaft coupling exterior space, reasonable selection different length shaft makes dial gauge in limited or enclosure space
With good, reach measurement purpose.
4, select minor diameter shaft, reduce fixed mechanism weight, because caused by weight fixed mechanism deform to measurement accuracy
Influence reduce.

Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
As shown in Figure 1, a kind of novel dial gauge fixed mechanism, is suitable for outer circle, the double dial gauge methods in end face, for by 2
The measuring point of dial gauge 7 is located in the side or end face of 8 measurement end of shaft coupling, specifically includes expansion set 1, connector 2, backing plate 3, connection
Bar 4, pole band 5 and shaft 6.8 reference edge of shaft coupling is equipped with axial pin hole 9, and in pin hole 9, backing plate 3 passes through swollen 1 expansion set of expansion set
Set 1 and connector 2 are fixed on the end face of 8 reference edge of shaft coupling, and the 4 axial setting of vertical shaft coupling 8 of connecting rod, one end is fixed on pad
On plate 3, the other end is connect by pole band 5 with 6 one end of shaft, and dial gauge 7 is fixed on 6 other end of shaft.Expansion can be used in expansion set 1
Bolt, connector 2 are screw rod matched with expansion bolt.
In order to more easily dismount, the expansion set 1 of the utility model is using cylindrical outer ring 11 and conical inner ring 12
Composite structure, outer ring 11 have the inner conical surface to match with 12 male cone (strobilus masculinus) of inner ring, and outer ring 11 and inner ring 12 all have axial lack
Mouthful, connector 2 includes bolt 21 and wing nut 22, bolt 21 pass through inner ring 12, outer ring 11, after backing plate 3 with wing nut 22
It is spirally connected.
In use, bolt 21 is passed through expansion set 1, it is packed into expansion set 1 in the pin hole 9 of 8 reference edge of shaft coupling, places in advance
