Description
Technical field
The present invention relates to a kind of ball indentation test machines more particularly to a kind of novel ball to press testing machine.
Background technique
Ball indentation test is a kind of measurement plastic hardness that International Organization for standardization is recommended in electrical safety field and nonmetallic
One of method of material thermal resistance, in test, by condition as defined in standard, with certain etc ball indentation test device certain
Temperature, regular hour are pushed down into nonmetallic, non-ceramic material surface to examine the examination of electric tool structure material thermal resistance
It tests, to guarantee that sample under high temperature operating conditions, there is enough support strengths, does not cause electrical safety hidden danger.Existing ball pressure
The counterweight of testing machine is more troublesome in adjustment process, inconvenient for operation, and manufacturing cost is high.
Summary of the invention
In view of the foregoing drawbacks, easy to operate the purpose of the present invention is to provide a kind of structure is simple, manufacturing cost it is low one
Kind novel ball presses testing machine.
Thus the technical scheme adopted by the invention is that:
Including load body and support, thermocouple is equipped in the support, the support side wall is equipped with thermocouple hole location, the load
Lotus body lower end is reverse taper, and the lower end of the reverse taper is equipped with steel ball, and the steel ball spherical radius is R2.5mm, on the support
End face is placed with sample, and steel ball spherical surface is pressed on sample, and the load body side surface is radially provided with through-hole, the company of being equipped in the through-hole
Extension bar, the both ends of the connecting rod are respectively equipped with counterweight, and the connecting rod both ends are respectively equipped with screw thread, and the counterweight is equipped with spiral shell
Line through-hole, the tapped through hole be threadedly engaged.
As a further improvement of the above technical scheme, the bending two ends of the connecting rod are downwards and with connecting rod center pair
Claim.
As a further improvement of the above technical scheme, load body upper end is equipped with threaded hole and communicates with through-hole, described
Lock-screw is equipped in threaded hole for locking connecting rod.
The invention has the advantages that
The configuration of the present invention is simple, it is easy to adjust to counterweight quick by using structure of the invention, so that connecting rod both ends balance,
Easy to operate, manufacturing cost is low.
Detailed description of the invention
