Description
Technical field
The present invention relates to detection technique field is examined, especially a kind of detection special fastening and loading device of thin-wall circular tube hardness.
Background technology
At present, pipe class workpiece need carry out hardness determination because tubing workpiece is hollow-core construction, if tube wall directly by
Pressure is very easy to deformation, causes measurement result inaccurate.In order to overcome drawbacks described above, the method for present testing crew generally use
Be to do a pipe plug, filled in and played a supporting role in pipe, but this method it is very high to the requirement on machining accuracy of pipe plug, it is necessary to
Pipe plug tightly coordinates with bore.It is same to influence measurement there are gap between pipe plug and inside pipe wall if machining accuracy is inadequate
As a result, and each sample be required for being equipped with a corresponding pipe plug, add the workload of staff.In addition, detect
Bi Hou, pipe plug is taken out from sample also more time-consuming.Especially when tube wall is relatively thin, held round using existing pipe plug branch
Manage accuracy that is very inconvenient, and cannot be guaranteed testing result.
The content of the invention
It is an object of the invention to make up the deficiencies in the prior art part, there is provided one kind design is reasonable, simple in structure, uses
It is convenient, it can play a supporting role to thin-wall circular tube, improve the special clamping of detection thin-wall circular tube hardness of testing result accuracy
Device.
The purpose of the present invention is what is realized by following technological means：
One kind detection special fastening and loading device of thin-wall circular tube hardness, it is characterised in that：Including bottom plate, side plate, pull rod, support
Bar, handle, sleeve and spacing ring, one side plate of each side installation of plate upper surface, the upper surface of each side plate is made
Go out a mounting groove；Sleeve outer surface is co-axially mounted a spacing ring；A pull rod, the rear end of the pull rod are coaxially installed in sleeve
Extend on the outside of sleeve and be co-axially mounted a handle thereon, the front end of pull rod extends to the outside of the sleeve other end, and pull rod
Front end and sleeve lining be contact of incline plane, the coaxially connected supporting rod of front end face of pull rod；Pull rod and supporting rod are put respectively
Put in the mounting groove of two side plates in left and right.
Moreover, the mounting groove is V-shaped groove, a pressing plate, the lower surface of the pressing plate are respectively provided with above each mounting groove
Make arc groove；On side plate, the other end is installed on side plate one end hinge of the pressing plate by jackscrew.
Moreover, the front portion of the pull rod and posterior face are designed with scale.
Moreover, the bottom surface of the bottom plate installs an alignment pin.
The advantages and positive effects of the present invention are：
1st, the pull rod of the present apparatus and sleeve can fix round tube inner wall progress top pressure, ensure that pipe is carrying out hardness measurement
Shi Buhui is deformed because of stress, so as to improve the accuracy of measurement result.
2nd, the pull rod of the present apparatus and sleeve use contact of incline plane, its not only uniform force application, and sleeve has certain bullet
Property, therefore can be used for the pipe for fixing a variety of internal diameters.Compared with traditional pipe plug, reduce the usage quantity of pipe plug.In addition,
When dismantling pipe, it is only necessary to release pull rod forward, sleeve can restore to the original state, and easily can take out the pipe after detection.
3rd, the present apparatus is connected to supporting rod in the front end of pull rod, its design can play balanced action, avoid pull rod one end from hanging
The phenomenon that accuracy of detection is influenced when sky is set occurs, so as to further increase the accuracy of detection.
4th, the front portion of present apparatus pull rod and posterior face are designed with scale, observable pull rod front end enter sleeve away from
From avoiding enter into too many, cause barrel forward end and rear end the phenomenon of unbalance stress occur.
5th, the present invention is the detection thin-walled that a kind of design is reasonable, simple in structure, easy to use, easy to manufacture, specificity is strong
The special fastening and loading device of pipe hardness, detection difficulty, the standard accelerated detection speed, improve measurement result can be reduced using the present apparatus
True property.
