Description
Technical field
The utility model relates to calibrating installation, specifically Shore durometer test force calibrating installation.
Background technology
Shore hardness test is the peculiar hardness test of rubber and plastics, for the mensuration of finished product and semi-manufacture hardness performance to control the quality of rubber and plastic product.In the calibrating of Shore durometer, test force calibrating is most important technical indicator.Conventionally adopt balance-type type dynamometer to examine and determine Shore durometer, during certificate test power, sclerometer is fixed on to a side of balance-type type dynamometer, at opposite side, places power value counterweight, the power value that during Balance, more scleroscopic reading is corresponding and the add power value of counterweight.The column dynamometer link contacting with the axis of Shore durometer pressing on balance-type type dynamometer, little and the dimpling of its apex area, when contacting, both very easily rock, simultaneously, the structures shape of balance-type type dynamometer its calibrating shore hardness timing, angle between its dynamometer link axis and Shore durometer pressing axis is not zero, and the pressing of Shore durometer can produce relative displacement on dynamometer link, so that the indicated value instability of Shore durometer.In addition, what balance-type type dynamometer utilized that counterweight obtains is discontinuous single-point hardness number, and range limitation, and adaptive surface is narrow.Therefore, design simple in structure, can obtain continuous hardness number and range is large, precision is high, indicating value is stable, the Shore durometer test force calibrating installation of convenient data processing is very necessary.
Summary of the invention
That the purpose of this utility model is to provide is simple in structure, can obtain continuous hardness number and range is large, precision is high, indicating value is stable, the Shore durometer test force calibrating installation of convenient data processing.
For achieving the above object, the utility model adopts following technical scheme: Shore durometer test force calibrating installation, comprise base, worktable, lifting handwheel, screw mandrel, sway brace, lifting nut, upper grip, lower chuck, upper grip lifting knob, fast clamp handle and lock-screw, worktable is arranged on base and can moves up and down by lifting handwheel, screw mandrel is vertically fixed on base, one end of sway brace is socketed on screw mandrel and is vertical with screw mandrel, the other end of sway brace is provided with upper grip, lower chuck, upper grip lifting knob and fast clamp handle, on upper grip, be provided with lock-screw, lifting nut coordinates the height of adjustment and fixed support arm with screw mandrel, what it is characterized in that worktable also arranges above strong sensor, the signal output part of power sensor is connected with the signal input part of scale load measuring instrument.
Further, described power sensor is also provided with above pressing protective sleeve.
Further, the signal output part of described scale load measuring instrument and the signal input part of computing machine are connected.
Further, the range of described power sensor is 1kg～5kg, and precision is not less than 0.08%FS.
Structure of the present utility model has guaranteed that the angle between its dynamometer link axis and Shore durometer pressing axis is zero, and the power sensor of employing applies test force continuously, can not only obtain continuous hardness number, also can be connected with computing machine and carry out data processing.The utility model is simple in structure, range is large, precision is high, indicating value is stable.
