Abstract
The utility model relates to a standard dynameter with raster digital display for detecting the load of a material testing machine or other force values, belonging to the technical field of force measurement, which comprises an elastic body and a measuring mechanism. The utility model is mainly characterized in that the elastic body is in the shape of a hollow column, and the measuring mechanism comprises a lever mounted inside the elastic body, a grating sensor contacted wit the contact point of the level, and a digital indicator. The utility model has the advantages of simple structure, convenient operation, direct viewing, easy reading, and the force value can be directly displayed.
Description
The utility model relates to the dynamometry field of measuring techniques, is a kind of Grating Digital display standard dynamometer that other power values were loaded, also be can be used for measuring to the calibrating Material Testing Machine that is mainly used in.
The measurement mechanism of known grade IIIstandard dynamometer (hereinafter to be referred as dynamometer) has two kinds of frame modes: a kind of is the percentage tabular form; Another kind is that mercury is box.After percentage tabular form dynamometer was stressed, elastomeric distortion was measured by dial gauge, and the measurement display result is a length value, needed just can obtain the power value through calculating.Again because dial gauge is the gear transmission structure form, when using dynamometer calibrating Material Testing Machine load, for eliminating gash spacing error, stipulate in JJG144-82 " grade IIIstandard dynamometer " vertification regulation: " on dial gauge during reading; use resilient spillikin, rap the middle part, surface of dial gauge." this " rapping " not of uniform size, varies with each individual, and often causes personal error.Also, also bring artificial reading error because the precision of dial gauge is the quantitative value of 1/100, thousand fen position can only read by estimating.After the box dynamometer of mercury was stressed, elastomeric distortion was measured by mercury slug, and reading is very inconvenient, and environment temperature is very big to the indicating value influence, and mercury is harmful.
The purpose of this utility model is, provides a kind of simple in structure, easy to use and can directly show the Grating Digital standard dynamometer of power value.
Task of the present utility model is achieved in that as shown in drawings, it comprises elastic body (3) and measuring mechanism composition, special character of the present utility model is: elastic body (3) is a hollow cylindrical, the compression leg of measuring mechanism (4) matches with the hole of elastic body (3), lever (5) is placed on the support (6), the upper contact of lever (5) contacts with compression leg (4), support (6) places in the elastic body (3) and is fixed on the elastic body (3), the lower contact of lever (5) contacts with the sensing head of grating sensor (9) in being placed on elastic body (3) side opening, and grating sensor (9) is connected with digital indicator (10) by cable.
Measuring mechanism of the present utility model can also be connected with computing machine, and measurement result is carried out data processing or printing, has danger to pick up the metering of power value to some, can also adopt remote measurement or remote control to realize.
Dynamometer of the present utility model is because elastic body is the hollow cylindrical structure, and the thickness (a) and the width (b) that change open column just can easily change the ability that elastic body bears load; Dynamometer with the same specification of known ES type is compared, and weight can alleviate 2/3rds; The elastomer structure complexity of known dynamometer, manufacturing procedure is various, car is arranged, mill, machining operation such as plane, mill, and elastomeric processing of the present utility model is mainly finished by turner.Can save man-hour 2/3rds.
Have simple in structure, easy to use, and can directly show the power value, advantages such as readability directly perceived.
Dynamometer precision of the present utility model is 0.3/100, and it is identical with known dynamometer that every technical indicator meets the requirement of ZBN74002-89 " testing machine verification standard dynamometer " and JJG144-82-" grade IIIstandard dynamometer " vertification regulation.
Accompanying drawing has been described an embodiment of the present utility model.
Accompanying drawing 1 is a dynamometer structural representation of the present utility model.
Accompanying drawing 2 is the side view of accompanying drawing 1.
With reference to attached Fig. 1 and 2, elastic body (3) is a hollow cylindrical, matches with base (8).The compression leg of measuring mechanism (4) matches with the hole of elastic body (3), lever (5) is placed on the support (6), the upper contact of lever (5) contacts with compression leg (4), support (6) places in the elastic body (3), the bottom face of support (6) is provided with the hole, with the hole of screw by its bottom face support (6) is fixed on the elastic body (3), spring (7) makes lever (5) usefulness that resets.The lower contact of lever (5) contacts with the sensing head of grating sensor (9) in being placed on elastic body (3) lateral aperture, and grating sensor (9) and digital indicator (10) are the auxiliary products of known technology, and its precision is 1/1000.
During use, load is added on the upper press cover (1), pass to elastic body (3) by steel ball (2), elastic body (3) is stressed and be out of shape, the measurement of distortion is the contact of being depressed lever (5) by compression leg (4), and distortion is after the lever of 10:1 amplifies, and the lower contact of lever (5) promotes the sensing head of grating sensor (9), signal is delivered to digital indicator (10) by cable, carries out the power value by digital indicator (10) again and show.
Claims (2)
1, a kind ofly be used to measure the power value, particularly examine and determine the Grating Digital display standard dynamometer of Material Testing Machine load, comprise: elastic body (3) and measuring mechanism are formed, it is characterized in that: the compression leg of measuring mechanism (4) matches with the hole of elastic body (3), lever (5) is placed on the support (6), the upper contact of lever (5) contacts with compression leg (4), support (6) places in the elastic body (3) and is fixed on the elastic body (3), the lower contact of lever (5) contacts with the sensing head of grating sensor (9) in being placed on elastic body (3) side opening, and grating sensor (9) is connected with digital indicator (10) by cable.
2, Grating Digital display standard dynamometer according to claim 1 is characterized in that: elastic body (3) is a hollow cylindrical.
