Abstract

The utility model discloses a comparer for a cast aluminium alloy fast measurer, which is composed of a bottom board, measuring arms, a testing head, an electric clamping head, etc. Totally three pairs of measuring arms are arranged, and each pair of measuring arms is provided with fours pairs of testing contact heads. The electric clamping head is composed of two knife blades fixed on a spring leaf, etc. The utility model has small resistance when a sample is loaded, high speed and accurate testing, and meets the test requirement of cast aluminium.

Description

Multi-function casting aluminium alloy tacheometer comparer

The utility model relates to a kind of comparer that is used for multi-function casting aluminium alloy tacheometer.

Aluminium alloy can change its as-cast structure and mechanical property significantly through refining, the rotten processing.To the detection of refining, modification effect (metallographic grade, alterant residual quantity) and cast aluminium tissue, mechanical property, adopt conventional physico-chemical analysis method and instrument thereof to carry out usually, but this only is product inspection afterwards, and analysis time is long, the expense height at present.Name is called that " (patent No.: patent of invention 86102192.4) discloses the method and the measuring instrument thereof of a kind of usefulness " level than method " test cast iron for cast iron method for rapidly testing and measuring instrument thereof.Though this method and measuring instrument have solved the difficulty of cast iron stokehold fast quantification test substantially, this measuring instrument still has following weak point: 1, gage beam is too much, promptly causes waste, can not adapt to cast aluminium test needs again.2, the electric chuck first half of this measuring instrument is a serrate, and Lower Half is the garden arc, and the resistance of the sample of packing into is big, and speed is slow, contacts inhomogeneously with sample, easily causes poor electric contact, influences measuring accuracy.

The purpose of this utility model provides a kind of easy to use, and test speed is fast, and the precision height meets the multi-function casting aluminium alloy tacheometer comparer of testing the cast aluminium requirement.

The utility model comprises base plate 1, the gage beam on the base plate 1, and test contact on the gage beam and the electric chuck 5 that is positioned at the gage beam both sides, lead-in wire 2, said gage beam is provided with three pairs altogether, i.e. gage beam 3a, 3a '; 3b, 3b '; 3c, 3c '; Be equipped with the test contact of four pairs of mutual insulatings on the every pair of gage beam, i.e. test contact 4a, 4a '; 4b, 4b '; 4c, 4c '; 4d, 4d '.Electricity chuck 5 is 10mm with the spacing of test contact, and all the other test contact spacings are 60mm, 30mm, middle two couples of test contact 4c, 4c '; 4d, 4d ' are than all the other two couples of test contact 4c, 4c '; 4d, 4d increase 3mm.Electricity chuck 5 is made up of blade 5a, the 5a ' that symmetry is fixed on the spring leaf 5b, spring leaf 5b is fixed on the cross-over block 5d through pressing plate 5c, the cutter of blade 5a, 5a ' is wide to be 1-2mm, be 15 ° of angles with vertical direction, 3 at the two blade lower extreme points of blade 5a, 5a ' and the mid point between pressing plate 5c are on the same garden of 18mm at diameter.

Because gage beam of the present utility model is established three pairs altogether, a pair of is reference arm, and two pairs can be gage beam in addition, meets cast aluminium test needs.Electric chuck of the present utility model is made up of two blades that are fixed on the spring leaf, and cutting edge does not have sawtooth, and resistance is little when packing sample into, and speed is fast, electrically contacts well, and test accurately.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model electricity chuck structure synoptic diagram.

Further describe the utility model below in conjunction with accompanying drawing.

Referring to accompanying drawing 1, physical dimension and structure are identical, and three couples of gage beam 3a, 3a ' being parallel to each other,

gage beam

3b, 3b ', and

gage beam

3c, 3c ' are packed on the base plate 1.

Gage beam

3c, 3c ' are reference arm, and in order to installation code coupon 6c, gage beam 3a, 3a ',

gage beam

3b, 3b ' are respectively in order to install isotype two tensile bar 6a, 6b.Standard coupon 6c and chest-developing bar 6a, 6b are fixing by the electric chuck 5 of the gage beam left and right sides respectively.Equal upper and lower settings four couples of measuring head 4a, 4a ' on every pair of gage beam; 4b, 4b '; 4c, 4c '; 4d, 4d ', each measuring head all are packed on the gage beam through fixing screwed pipe 4.Lead-in wire 2 links to each other with fixing screwed pipe 4, and the spacing of test contact 4c, 4d is about 30mm, and the spacing of test contact 4c, 4b is 60mm.Middle two couples of measuring head 4c, 4c ',

test contact

4b, 4b ' are than test contact 4a, 4a ', 4d, the about 3mm of 4d ' growth.

Referring to accompanying drawing 3, blade 5a, 5a ' left-right symmetric are fixed on the top of spring leaf 5b, spring leaf 5b is fixed on the cross-over block 5d through pressing plate 5c, blade 5a, 5a ' first half are blade, tread is 1-2mm, and being 15 ° of angles with vertical direction, 3 at the mid point of two blade lower extreme points and pressing plate 5c is that the same garden of 18mm is on week at diameter.The Lower Half of blade 5a, 5a ' is a vertical plane, does not contact with coupon during test.
