Description
Technical field
The utility model relates to detection technique field more particularly to a kind of disk-like accessory large cylindrical and short and small outer circle portables
Coaxiality check fixture.
Background technique
Determine vortex is the important part of screw compressor, and large cylindrical and the concentricity of cylinder where sealing surface are to directly affect
The requirement of the important technology of assembly and performance.Since large cylindrical outer diameter and small outer circle outer diameter quantity difference are very big, small outer circle compares again
It is short, it measures relatively difficult.
Three coordinates are generally used in the measurement of this numerical value, and head inspection, process detection frequency are high, and when three coordinate measurements needs constant temperature to examine
It is just accurate to survey, and process equipment can only just shut down waiting as a result, loss efficiency, night shift also need to arrange three to sit when three coordinate measurements
Mark person works.Alternatively, it is also possible to make special pneumatic cubing, cost is higher.
Utility model content
The utility model is to solve the above problems, provide a kind of disk-like accessory large cylindrical and short and small outer circle portable concentricity
Cubing.
In order to solve the above technical problems, the technical solution of the utility model is: disk-like accessory large cylindrical and short and small outer circle are just
Prompt formula coaxiality check fixture, including equipotential disk, table bracket, amesdial and pedestal；Table bracket includes connection vertical bar and cross in 90 °
The bottom end of bar, vertical bar is mounted on the base, and the side horizontal of cross bar is equipped with amesdial, and the end of amesdial passes through cross bar and inspection
The small outer circle in top for surveying workpiece is in contact and is fastened by being located at the fastening screw at the top of cross bar；Equipotential disk include disc and
Ladder supports column, the top of ladder supports column are fixedly connected with the end face of disc, excircle and the detection workpiece of disc
Lower part large cylindrical is in contact, and the bottom of ladder supports column is fixed in pedestal.
Further, pedestal is rectangular configuration.
Further, Yuan Du≤0.003mm of disc.
Further, Yuan Zhu Du≤0.005mm of disc.
Further, the material of disc is T10.
Further, the excircle of disc uses Carburization Treatment.
The utility model solves the problems, such as size outer diameter concentricity, convenient and efficient, is suitble to scene to use, batch production；It is existing
A possibility that field uses, and is not required to constant temperature, and operator can detect at any time, reduces defective products；It is easy to operate, intuitive reflection as a result,
It is suitable for batch production.

Disk-like accessory large cylindrical and short and small outer circle portable coaxiality check fixture, including equipotential disk 1, table bracket 3, amesdial
5 and pedestal 6；Table bracket 3 includes connecting vertical bar and cross bar in 90 °, and the bottom end of vertical bar is mounted on pedestal 6, the side of cross bar
It is horizontally installed with amesdial 5, the end of amesdial 5 passes through cross bar and is in contact with the small outer circle in top for detecting workpiece 2 and passes through position
Fastening screw 4 at the top of cross bar fastens；Equipotential disk 1 include disc and ladder supports column, the top of ladder supports column with
The end face of disc is fixedly connected, and the excircle of disc is in contact with the lower part large cylindrical of detection workpiece 2, ladder supports column
Bottom is fixed in pedestal 6.
The pedestal 6 is rectangular configuration.
Yuan Du≤0.003mm of the disc.
Yuan Zhu Du≤0.005mm of the disc.
The material of the disc is T10.
The excircle of the disc uses Carburization Treatment.
In use, amesdial 5 is fixed on pedestal 6 with table bracket 3 and fastening screw 4, it is (fixed that when measurement, will test workpiece
It is vortexed) 2 large cylindricals lean against on equipotential disk 1,5 gauge outfit of amesdial are pressed in the small outer circle of detection workpiece 2, rotation detection workpiece
2 one circles, can measure concentricity.Through with three-dimensional coordinates measurement result repeatedly compared with, as a result unanimously.
More than, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art is in the technical scope that the utility model discloses, according to the utility model
Technical solution and its utility model design be subject to equivalent substitution or change, should all cover the protection scope of the utility model it
It is interior.
