Abstract
The utility model discloses a riveted joint tensile test clamp is slightly pressed to cross mound, include chuck and the fixed plate of being connected with the chuck, wherein: the chuck is upper grip and lower chuck, and the fixed plate is an upper fixed plate and bottom plate, an upper fixed plate goes up the sheet material with the riveting joint and is connected to fixing on the upper grip, being equipped with the shrinkage pool in upper grip and contact department of last sheet material, the upper grip passes through the shrinkage pool and is connected with the bump that the riveting connects. The sheet material was connected under the bottom plate connected with the riveting to fix under on the chuck. These anchor clamps simple structure, easy dismounting, and easily operation, putting at upper grip bottom central point and having set up interior counter bore, can guarantee can not receive the damage at tensile process middle connector, and the central atress direction that connects is unchangeable, tensile test is effectual, can appraise the tensile strength of articulate through tension failure betterly.
Description
Technical field
The present invention relates to fixture, specially a kind of cross upset joint tensile test fixture that presses.
Background technology
As the technical process for riveting is simple, with reliable and stable bonding strength, and breaks down, no
Limited by connection plate, the connection being adapted between baroque various metals and nonmetallic materials is widely used at present
In the manufacturing industry such as aircraft, automobile, five metals.But as the requirement to riveted structure and riveting process is improved constantly, quality also will
Improve constantly, and the tensile strength of jointing is to check one of index of riveting quality.
The content of the invention
It is the invention aims to provide a kind of easy accessibility, simple to operate, good a kind of cross of shearing test effect
The upset joint tensile test fixture that presses.
Realization the technical scheme is that：
A kind of cross upset joint tensile test fixture that presses, including chuck and the fixed plate being connected with chuck, wherein：
Chuck is upper grip and lower chuck, and fixed plate is upper mounted plate and bottom plate；
Upper mounted plate is connected with plate on riveted joint, and is fixed on upper grip, in upper grip and upper plate contact position
Shrinkage pool is provided with, upper grip is connected with the salient point of riveted joint by shrinkage pool.
Bottom plate is connected with plate under riveted joint, and is fixed on lower chuck.
It is an advantage of the invention that：This clamp structure is simple, easy accessibility, and easily operated；In upper grip bottom centre position
Put and be provided with interior counterbore, ensure that joint will not receive damage during stretching, and the center stressed direction of joint is not
Become, tension test effect is good, the tensile property of joint connection preferably can be evaluated by tensile failure.
Description of the drawings
Schematic diagrams of the Fig. 1 for apparatus of the present invention；
In figure：1. 2. bolt of upper grip（Six）3. upper mounted plate（Two pieces）4. plate 6. on plate 5. is descended
Bottom plate（Two pieces）7. nut（Six）8. lower chuck.
Specific embodiment
As shown in figure 1, a kind of cross upset joint tensile test fixture that presses of the present invention, by upper grip 1, lower chuck 8,
The upper plate 5 of riveted joint is led to by upper mounted plate 3, bottom plate 6 and the part such as bolt 2 and nut 7 composition, upper mounted plate 3
Cross bolt 2 and nut 7 is fastened on upper grip 1, the lower plate 4 of riveted joint is passed through bolt 2 and nut by bottom plate 6
7 are fastened on lower chuck 8；Upper grip 8 is provided with a counterbore where contacting with upper plate 5, so as to ensure the convex of joint
Point has enough spaces, will not be destroyed.
The present invention clamping process be：
（1）Upper grip 1 is placed on joint, is made in the counterbore that joint is put in upper grip completely, and with lower chuck 8
Center alignment, it is ensured that joint is during tension all the time on centrage；
（2）By the lower plate 4 of riveted joint with two pieces of bottom plates 6, fixed by four bolts 2 and four nuts 7
On lower chuck；
（3）With two pieces of upper mounted plates 3 by the upper plate 5 of riveted joint, fixed by two bolts 2 and two nuts 6
On upper grip 1, that is, complete the clamping of part.
（4）Clamping fixture is arranged on hydraulic extension test machine, you can carry out the tension test of riveted joint.
