Description
Technical field
The utility model belongs to cubing technical field, concretely relates to a kind of adjustable concentric shafts degree cubing.
Background technique
Concentricity is to evaluate an important technology index of cylindrical work, and coaxiality error directly affects the dress of workpiece
Match and uses.
Currently, the detection for disk-shaped part concentricity, can be used and measure on vernier caliper or three-coordinates measuring machine, trip
Mark calliper to measure precision is not high, and compare other measurement method low efficiencys；Three-coordinates measuring machine is at high cost, produces in small lot
When, not economical enough with this detecting instrument detection disk-shaped part concentricity, general midget plant also lacks this measuring instrument.
The application documents of application number CN201010501023.2 disclose a kind of coaxiality check tool device, and it includes pedestal
(1), a fixed bearing (6) and two expansion bearings (2), fixed bearing are equipped with by key (3) fastening on the pedestal (1)
(6) it is equipped with immovable high-precision radial bearing, expansion bearing (2) is equipped with moveable high-precision radial ball bearing.
The above structure that the present invention uses can substitute the concentricity of three-coordinates measuring machine measurement disk-shaped part, not only at low cost, and
It is easy to use.
But it is in the presence of structure is complicated, and precision is not easy to control and uses relatively complicated problem.
Summary of the invention
A kind of the purpose of the utility model is to provide structures simple, at low cost and coaxiality check fixture easy to use.
In order to solve the above technical problems, purpose of the utility model is realized as follows:
A kind of adjustable concentric shafts degree cubing, including pedestal and the clamping device being movably connected on the pedestal；
The guide groove of radial arrangement is offered on the pedestal；
The clamping device includes the clamping part being flexibly connected with the guide groove；
The clamping part include with the sliding block of the guide groove clearance fit, be located above the sliding block and with the sliding block
It is bolted adjusting block, one end that the adjusting block is directed toward base center is fixedly connected with clamping head；
The clamping head includes to be fixed on adjusting block and the shaft vertical with the pedestal and be movably connected on described
Idler wheel in shaft.
Preferred embodiment on the basis of above scheme and as above scheme: the idler wheel is placed at least two vertically
It is a.
Preferred embodiment on the basis of above scheme and as above scheme: the idler wheel is bearing, bearing inner race set
If in the shaft.

Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the attached drawing in embodiment, to reality
The technical solution applied in example is clearly and completely described:
A kind of adjustable concentric shafts degree cubing, including pedestal 10 and the clamping device being movably connected on pedestal 10 20；
The guide groove 11 of radial arrangement is offered on pedestal 10；
Clamping device 20 includes the clamping part being flexibly connected with guide groove 11；
Clamping part includes to be bolted with the sliding block 21 of 11 clearance fit of guide groove, above sliding block 21 and with sliding block 21
Adjusting block 22, one end that adjusting block 22 is directed toward 10 center of pedestal are fixedly connected with clamping head 23；
Clamping head 23 includes to be fixed on adjusting block 22 and the shaft 231 vertical with pedestal 10 and be movably connected on shaft
Idler wheel 232 on 231.
In the present embodiment, preferably there are two the vertical arrangements of idler wheel 232, setting can make clamping head 23 and quilt there are two idler wheel
It examines workpiece and forms two contact points, in manual rotation process, testing staff is often unbalanced to examined workpiece force, then
It will lead to examined workpiece deflection and lead to measurement inaccuracy, more than one contact point all can preferably be offset in rotation process
The out-of-balance force being subject to prevents examined workpiece from causing examined workpiece to lead to axis offset due to unbalance stress in manual rotation
The problem of, lead to the problem that measurement error is excessive.
Idler wheel 232 is high-precision bearing, bearing inner race be arranged in shaft 231, the outer peripheral surface of bearing outer ring and tested work
Part periphery face contact.
Preferably, pedestal 10 is dish type；In addition, for the ease of by pedestal 10 it is good be fixed to detection platform on, the bottom of at
10 middle part of seat offers counter sink 12, so that it may the counter sink 12 is passed through by fixing bolt, so that pedestal is fixed on detection
On platform, while bolt is sunk in pedestal, will not influence detection.
Preferably, in order to guarantee that clamping part being capable of smooth sliding and the clamping part after clamping examined workpiece in adjustment process
There can be good stability, it is dovetail groove or T-slot that slot 11 is preferably directed in the present embodiment, and sliding block 21 has phase with guide groove 11
The structure answered.
Specific application method are as follows:
Clamping head 23 is adjusted, makes the outer peripheral surface of idler wheel 232 and the periphery face contact of examined workpiece 30, then screwing bolts
24, tense adjusting block 22 in guide groove 11 sliding block 21, so that clamping head 23 is fixed on chassis 10, to realize aid
Mechanism gets to the concentricity institute for needing to detect by examined workpiece clamping position, using Magnetic gauge stand support dial gauge clamping dial gauge
In the position of circumferential surface, rotates examined workpiece and detected.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
