Abstract
The invention discloses a kind of portable hardometer auxiliary moulds, and including upright bar, the upright bar is equipped with the detection tablet slided up and down along upright bar, and a guide rod is fixed in upright bar lower vertical；One is cased on the guide rod for upright bar to be supported on to the supporting rack on workpiece, the center of gravity ball by filament hanging is equipped with below guide rod.The present invention has the advantages that simple in structure, manufacture is at low cost, and solves the problems, such as that portable hardometer is difficult to find that peak so that detection is inaccurate to camshaft journal surface cylindrical surface.
Description
Technical field
The present invention relates to a kind of tooling for measuring hardness, more specifically, it relates to a kind of portable hardometer auxiliary mould.
Background technology
Originally the hardometer in workshop is fixed bench mounted hardness tester, and has a certain range to the diameter of the outside cylinder of camshaft
Limitation, this hardometer can not be used by directly resulting in part large size camshaft.And portable hardometer is in centering cylindrical surface highest
Stability is held in point and detection process larger difficulty, so that having during detection inaccurate.
Invention content
The technical problem to be solved by the present invention is to be directed to the above-mentioned deficiency of the prior art, it is auxiliary to provide a kind of portable hardometer
Assistant engineer fills, which can be quickly found out the peak of cam face, detect the hardness of camshaft, simple in structure, take
Band is convenient.
It is the technical scheme is that such:A kind of portable hardometer auxiliary mould, including upright bar, the upright bar
The detection tablet slided up and down along upright bar is equipped with, a guide rod is fixed in upright bar lower vertical；A use is cased on the guide rod
Be equipped with the center of gravity ball by filament hanging below supporting rack upright bar being supported on workpiece, guide rod.
Further, the supporting rack is the annular solid of upper opening, and the detection tablet is located at the upper of supporting rack
Portion opening portion.
Further, support frame as described above lower inside both sides are respectively provided with the cushion block of support workpiece, in supporting rack
Upside both sides are respectively equipped with the second screw being fixed on supporting rack on workpiece.
Further, the detection tablet is equipped with the open slot convenient for determining test position.
Further, the detection tablet by the first screw lock in upright bar.
Advantageous effect
Compared with prior art, the present invention the structure of the present invention is simple, manufacture is easy, easy to install and use, easy to carry,
Suitable for the hardness determination in different occasions, different size camshaft；Portable hardometer can effectively be solved and be difficult to centering circle
The problem of swinging when cylinder peak and inspection, can easily and quickly detect the hardness of camshaft, convenient and practical.

Fig. 2 is the left view of the portable hardometer auxiliary mould of the present invention；
Fig. 3 is the vertical view of the portable hardometer auxiliary mould of the present invention.
In figure：1st, the first screw, 2, detection tablet, the 3, second screw, 4, supporting rack, 5, cushion block, 6, upright bar, 7, filament,
8th, center of gravity ball, 9, guide rod.
Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
The embodiment of the present invention is such：As shown in Figures 1 to 3, a kind of portable hardometer auxiliary mould, including upright bar
6, the detection tablet 2 slided up and down along upright bar 6 is equipped in upright bar 6, detection tablet 2 is equipped with screw hole, can pass through the first spiral shell
1 locking of nail is fixed on detection tablet 2 in upright bar 6, and unscrewing the first screw 1 can allow detection tablet 2 to glide in upright bar 6
It is dynamic, to adapt to the bent axle hardness determination of different-diameter；The open slot convenient for determining test position, side are equipped on detection tablet 2
Just portable hardometer is placed to be detected the points hardness of workpiece；A guide rod 9, institute are fixed in the lower vertical of upright bar 6
It states and one is cased on guide rod 9 for upright bar 6 to be supported on to the supporting rack 4 on workpiece, supporting rack 4 can slide on guide rod 9, with suitable
Answer different measurement positions；Supporting rack 4 in the present embodiment is the annular solid of upper opening, convenient for supporting rack 4 is sleeved on bent axle
End, the detection tablet 2 are located at the upper opening portion of supporting rack 4；The weight by 7 hanging of filament is equipped with below guide rod 9
Bulbus cordis 8；Upright bar 6 can be made to remain vertical state.
In the present embodiment, 4 lower inside both sides of support frame as described above are respectively provided with the cushion block 5 of support workpiece, are used for
Prevent supporting rack 4 from sliding；Be respectively equipped with the second screw 3 supporting rack 4 being fixed on workpiece on the upside both sides of supporting rack 4,
Supporting rack 4 is fixed on by two the second screws 3 on workpiece.
When the present invention is specifically used, first cushion block 5 with supporting rack 4 by lock-screw is fixedly connected, supporting rack 4 is sleeved on
On guide rod 6, then detection tablet 2 is attached in upright bar 6, center of gravity ball 8 is hung in the lower section of guide rod 6, filament 7 and center of gravity ball 8 with filament 7
Upright bar 6 is made to keep vertical by center of gravity effect, at this moment adjust supporting rack 4, the vertical groove on supporting rack 4 is made to be overlapped with filament 7, with
This ajusts supporting rack 4.
Continue that tooling is kept to be in vertical state, supporting rack 4 is placed on camshaft mandrel end, is positioned by cushion block 5, mobile inspection
Master plate 2 is contacted with camshaft journal outer circle, tightens the first screw 1 and detection tablet 2 is fixed in upright bar 6, and at this moment detection is flat
Even if the cam arc-shaped surface peak measurement range in the range of 2 intermediate open channel of plate, so as to obtain the peak of cam face
Test position, detection tablet 2 are in same level with arc surface peak；Then it is in symmetrically to set by tightening 4 top of supporting rack
The second screw 3 put fixes camshaft, prevents camshaft from rolling, and portable hardometer can be smoothly placed on detection tablet 2,
Hardness determination is carried out to determining cam face peak test position.The auxiliary tool of the present invention has simple in structure, carrying
It is easy to assembly, suitable for the hardness determination in different occasions, different size camshaft；Cam face can rapidly and accurately be found out
The test position of peak can also fix camshaft, prevent from occurring camshaft rotation in detection process or tilt, effectively
It ensure that the accuracy of testing result.
What has been described above is only a preferred embodiment of the present invention, it should be pointed out that for those skilled in the art,
Without departing from the structure of the invention, several modifications and improvements can also be made, these all do not interfere with implementation of the present invention
Effect and practical applicability.
