Including installing the work platform on the sclerometer lead screw, off centre installs the position ball supporting seat on work platform, and the work platform side -mounting has balanced sticking together, be provided with balance lever on the ball supporting seat, install on the ball supporting seat balance lever fulcrum position, and the balance lever outer end sets up weight, the special pressure head of the inner installation of balance lever, installation three pearl workstations in work platform centre of a circle position top set up the gage block above the three pearl workstations, special pressure head sets up in three pearl workstations top. The utility model provides a calibrating installation's the not enough problem of the degree of accuracy of the metal rockwell hardness meter indentation degree of depth.
Description
Technical field
The utility model relates to measuring technique instrument field, is specifically related to metal Rockwell hardometer depth of cup calibrating installation, is mainly used in the measurement of the metal Rockwell hardometer depth of cup error of indication.
Background technology
The calibrating installation now existing patented claim that metal Rockwell hardometer depth of cup is measured, its principle of work uses clock gauge to be main standard device, with Rockwell hardometer initial load Compress Spring, spring makes the stressed generation displacement of bell crank, to change direction pass to clock gauge and measure metal Rockwell hardometer depth of cup by the bell crank of 1:5.This kind of design has following drawback in the application: 1) deformation can occur when spring stress, thus affect measurement result; 2) lever changes direction, violates abbe ' s principle; 3), while lever amplification displacement, the error of measurement result is also amplified thereupon.By taking into full account above-mentioned deficiency, present invention employs with gauge block is main standard device, balanced lever is utilized to balance the scleroscopic test force in metal Lip river, pressure head acts directly on gauge block, meet the principle of work of Rockwell hardometer, also meet abbe ' s principle, thus improve the accuracy of measurement result.The present invention is also had to trace to the source simple and easy, gauge block of directly tracing to the source.Measurement range of the present invention: (0 ~ 0.3) mm.Measurement result uncertainty: (
k=2); The technical conditions that standard GB/T/T230.2-2002 " metallic rockwell hardness test part 2: the inspection of sclerometer (A, B, C, D, E, F, G, H, K, N, T scale) and calibration " and JJG112-2013 " metal Rockwell hardometer vertification regulation " specifies can be met.At present, the accuracy Shortcomings of the calibrating installation of metal Rockwell hardometer depth of cup.
Summary of the invention
The utility model provides a kind of Rockwell hardometer depth of cup calibrating installation, and the utility model solves the problem of the accuracy deficiency of the calibrating installation of metal Rockwell hardometer depth of cup.
For solving the problem, the utility model adopts following technical scheme: a kind of Rockwell hardometer depth of cup calibrating installation, comprise the workbench be installed on sclerometer leading screw, on workbench, depart from center be provided with ball supporting seat, workbench side is provided with balance and sticks together; Ball supporting seat is provided with balanced lever, and balanced lever position of the fulcrum is installed on ball supporting seat, and balanced lever outer end arranges counterweight, and Special pressing head is installed in balanced lever the inner; Install three pearl worktable above workbench home position, arrange gauge block above three pearl worktable, Special pressing head is arranged at above three pearl worktable.
Advantage of the present utility model: structure is simple, and easy to operate, good stability, accuracy is high, can measure the sounding gear of Rockwell hardometer and superficial Rockwell hardness tester.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Symbol description in figure: gauge block group 1, workbench 2, Special pressing head 3, three pearl worktable 4, ball supporting seat 5, balanced lever 6, counterweight 7, balance stick together 8, sclerometer leading screw 9, micro-positioning regulators screw rod 10.
Embodiment
By best embodiment, the utility model is described in detail below
.
As shown in Figure 1, a kind of Rockwell hardometer depth of cup calibrating installation, comprises the workbench 2 be installed on sclerometer leading screw 9, departs from center and be provided with ball supporting seat 5 on workbench 2, and workbench 2 side is provided with balance and sticks together 8; Ball supporting seat 5 is provided with balanced lever 6, balanced lever 6 position of the fulcrum is installed on ball supporting seat 5, and balanced lever 6 outer end arranges counterweight 7, and Special pressing head 3 is installed in balanced lever 6 the inner; Install three pearl worktable 4, three pearl worktable 4 above workbench 2 home position and arrange gauge block above, Special pressing head 3 is arranged at above three pearl worktable 4.Arrange baffle plate in ball supporting seat 5 both sides, the pressing plate above baffle plate connects micro-positioning regulators screw rod 10, micro-positioning regulators screw rod is positioned at directly over balanced lever 6.
Described workbench 2 is apart from the installation supporting seat 5 in 40mm place, its center, and side is installed balance and sticked together 8.Special pressing head 3 is arranged on accredited Rockwell hardometer.U-shaped one end of balanced lever 6 is connected with simulation pressure head 3 with pin, then installs two baffle plates of ball supporting seat, is placed in by lever between two baffle plates, at the other end hanging counterweight of lever, balances the initial load of Rockwell hardometer.Then gently press lever to be placed on workbench by three pearl worktable, then be placed on three pearl worktable by the gauge block of 1.2mm, hand unclamps lever, allows pressure head touch gauge block, at this moment regulates scleroscopic zero point to zero.Again pressed gently by lever, the 1.2mm gauge block on three pearl worktable has been replaced with the gauge block of 1.18mm, unclamps lever, the difference of twice gauge block is 0.02mm, equals 10 Rockwell units, and the reading device of viewing Rockwell hardometer differs with standard value.Repeatedly change gauge block, mean allocation at least five point, until be calibrated to the full scale of sclerometer depth of cup.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
