Description
Technical field
A kind of portable Leeb Hardness Tester is the utility model is related to, belongs to rigidity detection device manufacturing field.
Background technology
Leeb Hardness Tester is a kind of test equipment, and its general principle is the impact body with certain mass in certain examination
The lower impact specimen surface of power effect is tested, measurement impact body utilizes electromagnetism away from the impact velocity at specimen surface 1mm and rebound speed
Principle, sense velocity voltage.Leeb Hardness Tester is mainly used in live hardness quick detection, and the generation of its error is past
The past operation with Site Detection personnel has certain relation, it is necessary to ensure that bulb impacts table to be measured with vertical direction in detection process
Face, this needs testing staff voluntarily to control the direction of Leeb Hardness Tester, when measuring the cylindrical surface hardness such as bolt, pipeline,
Easily cause the shake of percussion mechanism, it is difficult to the perpendicularity of Leeb Hardness Tester is controlled, so as to influence the standard of Leeb Hardness Tester measurement
True property.Found by live practical operation, when support ring can stablize support percussion mechanism, measured with Leeb Hardness Tester
For mutual difference between hardness number between 0-1.5HRC, and when percussion mechanism is shaken, same measurement position, same Richter scale are hard
Mutual difference between the hardness number that degree measurement measures has reached 8-10HRC.It follows that measure steel class with Leeb Hardness Tester
During product surface hardness, percussion mechanism support stability the accuracy and validity of measurement result are served it is vital
Effect.
Utility model content
Deficiency of the prior art, the technical problems to be solved in the utility model are more than：There is provided one kind can be to circle
Cylindrical curved surface workpiece carries out hardness determination, and the portable Leeb Hardness Tester that detection accuracy is higher.

In preferred embodiment：The side wall of cylinder 1 is provided with skid resistant course, can further prevent that percussion mechanism is trembled during detection
Dynamic, hardness determination accuracy is higher；The outside of loading sleeve 10 is provided with antiskid thread 11, hand and the phase of loading sleeve 10 when preventing from loading
To sliding, it is easy to load；The top of main frame 7 is provided with data communication charging inlet 8.
As shown in Figure 3, Figure 4, when in use, cylinder 1 is used for being supported on tested curve surface work pieces the utility model, passes through
The position for adjusting two cylinders 1 is allowed to and is tested curved surface full contact, you can ensures support ring 3 and the survey on tested curve surface work pieces
Pilot position is tangent, and detection accuracy is higher., can be by adjusting the position of fixed seat 5 for the curved surface of different curvature, and lead to
Cross locking nut 6 and carry out locking, you can realize that support ring 3 and the test point position on different curve workpiece are tangent.
Portable Leeb Hardness Tester described in the utility model, hardness determination can be carried out to cylindrical surface workpiece, and can
