Embodiment Construction
[0011] like figure 1 As shown, the rear end of the measuring lever 5 is installed on the measuring lever seat 1 and is constrained by the top 2 of the two rotating shafts so that it can swing freely. A movable and adjustable adjusting plate 3 is installed on the upper plane of the measuring lever 5, and a measuring tip 4 is installed on the adjusting plate 3; the adjusting plate 3 can translate together with the measuring tip 4 to adjust the lever ratio. The tip of the measuring tip 4 is in contact with the upper end surface of the main shaft 6 of the indenter of the hardness tester. Measuring lever 5 front ends contact with the measuring head of Rockwell special scale 7. The Rockwell special scale 7 and the measuring lever seat 1 are all fixed on the hardness tester housing 8 .
[0012] The displacement of the indenter spindle 6 of the hardness tester is transmitted to the measuring lever 5 through the measuring tip 4; after mechanical amplification, it is transmitted to th...

The invention discloses a gauge head-type three-use sclerometer. A measuring lever seat (1) is fixed on the case (8) of the sclerometer. The back end of a measuring lever (5) is flexibly connected with a rotor shaft apex (2) fixed on the measuring lever seat (1). The front end of the measuring lever touches and is connected with the gauge head of a Rockwell special-purpose gauge (7). The point of a measuring apex (4) arranged on the measuring lever (5) touches and is connected with the upper end face of the main shaft (6) of a penetrator. The invention discloses the gauge head-type three-use sclerometer adopting the measuring lever and the Rockwell special-purpose gauge. The structure of the invention is simple and clear, and completely achieves the functions of the prior optical lever, and the effects of facilitating maintenance, reduction of environmental sensitivity and improvement of the precision stability.
Description
technical field [0001] The invention relates to a hardness tester, in particular to a Blowy three-purpose hardness tester. Background technique [0002] In the past, Blowy three-purpose hardness testers all used optical levers and projection screens to realize the Rockwell hardness measurement function. This method has a complex structure, troublesome use and maintenance, is extremely sensitive to the use environment, and has poor precision stability. Contents of the invention [0003] The purpose of the present invention is to provide a meter-type three-purpose hardness tester. The technical problem to be solved is to overcome the shortcomings of the existing Buluowei three-purpose hardness tester optical lever measuring device with complex structure, difficult maintenance and poor stability. Rockwell hardness measurement is accurate and reliable, easy to use and maintain. [0004] Technical scheme of the present invention is as follows: [0005] A meter head type thre...
