Abstract
The utility model relates to a test part punctuating machine, comprising a mechanism for clamping or loosening the test piece, a mechanism for determining the calculated length of the test piece, and a mechanism for dotting, wherein, the mechanism for clamping or loosening the test piece and the mechanism for determining the calculated length of the test piece are composed of nut screws which are arranged on two-way screw rods and do the reverse direction rectilinear motion following the rotation of the two-way screw rods; a cam is manipulated to rotate, the mechanism for clamping or loosening the test piece can be caused to rise and fall; the mechanism for determining the calculated length of the test piece is fixedly connected with a needle punching device. A half gear is rotated to lift the needle punching device, and the punching needle is fallen by gravity to dot a point. The utility model is operated by machinery, and overcomes various defects of the prior art in dotting. The utility model has the advantages simple operation, easy fabrication, and released bulky manual work.
Description
It is the metering outfit of feature, particularly a kind of test specimen punctuating machine to adopt mechanical means that the utility model relates to a kind of.
Mechanical-testing halls such as industry science institution of higher learning, secondary specialized school technical school, steel plant, enginerring works, scientific research office, when the tension test of making metal material, all to get a segment length as computational length L, in order to measure the variation of distortion back length at the test specimen middle part.Each makes a call to a point to need at the two ends of test specimen computational length L, and this point is called gauge point, is called for short punctuate.In the prior art, adopt Hammer head and sample punctuate in a state of excitement, not only former at first heavy, and two difficult beating on same straight line of parallel test specimen axis of punctuates, the distance L between punctuate also is difficult to reach desired computational length.
The purpose of this utility model provides a kind of test specimen punctuating machine, it adopts the method for machinery to finish the task of mark point, overcome the above-mentioned deficiency and the defective of prior art fully, with the operation of mechanically actuated instead of manual, gauge point is more accurate, and work becomes light.
Realize specifically constituting of the utility model above-mentioned purpose: mechanism that clamps or loosen test specimen is positioned at the below of the mechanism of the mechanism that makes a definite test specimen computational length being synchronized with the movement and a mark point.
Accompanying drawing 1 is a structure principle chart of the present utility model
Accompanying drawing 2 is the utility model part-structure figure.
Wherein: 1-half gear sliding key shaft 6-camshaft 11-tooth bar
The two-way screw mandrel 7-of 2-body 12-half gear
3-test specimen 8-is bearing seat 13-nut slidably
4-spring clamp 9-cam 14-pointer
The two-way screw mandrel 10-of 5-index dial 15-nut
Below in conjunction with drawings and Examples in detail the utility model is described in detail, the hand of spiral on screw mandrel 5 and 2 both sides is opposite, both sides are equipped with nut 15 and 13 respectively, test specimen 3 is placed on screw mandrel 5 rotations and does simultaneously on the nut 15 of reverse linear motion, the variation of distance between the nut 15, just can clamp or unclamp test specimen 3, cam 9 is held the slidably bearing seat 8 that is connected with screw mandrel 5 from the bottom, the rotation of cam 9 makes and clamps or the tripping-gear lifting, two nuts 13 of doing the reverse linear motion with screw mandrel 2 rotations simultaneously, respectively with two root pointers 14, the shell of two toothed rack 11 is fixedly connected into two integral body, in be equipped with towards the spring clamp 4 of pin with after tooth bar 11 is fixedlyed connected, be contained in the shell of tooth bar 11, when above-mentioned two integral body move, driving tooth bar 11 and spring clamp 4 moves, two half gears 12 with tooth bar 11 engagements are parallel thereupon mobile along half gear sliding key shaft 1, body 7 is equipped with index dial 10, regulating two root pointers 14 refers on required computational length, after aforesaid operations is ready, rotate half gear 12, it will drive two tooth bars 11 respectively and rise to certain altitude, the effect that is allowed to condition at gravity and spring force is fallen, and promptly goes out punctuate on test specimen 3 towards pin.
This utility model, it is easy, simple to operate to make, and can not only accurately get qualified punctuate, and removes heavy manual labor.
