Abstract
The utility model discloses a bolt tensile strength test clamp, comprising a clamp block a (1) and a clamp block b (2). The clamp block a has the shape of a step cylinder, and an installation end (11) is arranged at the end with larger diameter of clamp block a and a clamping end (12) is arranged at the other end of clamp block a. A through hole (111) is arranged at one side of the installation end, and an installation groove which communicates to the through hole is arranged at the outside of the installation end. The clamp block b has the shape of a cylinder, and a thread hole which has the same axis as the clamp block b is arranged at one side of the clamp block b. The utility model is advantageous in that it saves the process of installation and adjustment and improves test efficiency, for clamp block a is not required to be taken off from a testing machine when a test bolt is being replaced; the bolt tensile strength test clamp is not easy to be broken since the bearing capacity of the function part between clamp block a, clamp block b and the test machine is strong; the bolt tensile strength test clamp has a large application scope, for it can be made according to different bolt models.
Description
Technical field
The utility model relates to a kind of anchor clamps, especially relates to a kind of bolt tension strength test anchor clamps.
Background technology
Bolt is a secure component main on the automobile, and the quality of bolt strength directly has influence on the reliability that automobile uses, so will carry out tensile strength test to the fastening bolt of various significant points on the automobile usually.When bolt is carried out sampling test, bolted fixture will be taken off from universal testing machine usually, change the bolt of being broken, because anchor clamps are heavier, and the bolt of test is more, makes that the time of changing anchor clamps is longer, causes test efficiency on the low side.The Chinese utility model patent instructions of the CN201152840Y that on November 19th, 2008 was announced discloses a kind of ordinary bolt/nut test fixture, fixture block and following fixture block carry out tension test to bolt in this anchor clamps utilization, because each test all will be taken off these anchor clamps from testing machine, make the time of single test increase, reduced test efficiency, and these anchor clamps and testing machine agency part are the flat disk, anchor clamps and testing machine contact site intensity are not high like this, when some high-strength bolt of test, easy-to-draw bad anchor clamps.
The utility model content
The utility model mainly is to solve test fixture efficient and the not high problem of intensity that exists in the prior art, and a kind of bolt tension strength test anchor clamps are provided, and this anchor clamps set-up time is short, intensity is high, has improved test efficiency effectively.
In order to solve the problems of the technologies described above, the utility model has adopted a kind of like this bolt tension strength test anchor clamps, these anchor clamps comprise fixture block a and fixture block b, described fixture block a is the step right cylinder, and the end that diameter is big is an installation end, and the end that diameter is little is a pinching end, be provided with a through hole in described installation end one side, this installation end outer face is provided with the mounting groove that connects described through hole, and described fixture block b is a right cylinder, at the fixture block b one end setting threaded hole coaxial with fixture block b.When carrying out the bolt tension strength test, the thread end of bolt is screwed into threaded hole on the fixture block b, the other end is installed on the fixture block a by the mounting groove on the fixture block a, and fixture block b is installed on the testing machine chuck.Like this when changing the test bolt, only need pull down the bolt broken end on fixture block b and the fixture block a, and fixture block a does not need from testing machine to take off, saved the operation of installing and adjusting, reduced test period, improved test efficiency, and the site of action of fixture block a and fixture block b and testing machine is a right cylinder, this right cylinder bearing capacity is strong, is difficult for being broken.Threaded hole on mounting groove on the fixture block a and the fixture block b can be made according to the model of different bolts, and is applied widely.
As preferably, described mounting groove one end connects described installation end lateral surface, and the other end is the arc surface coaxial with fixture block a.Do not need to adjust the right alignment of fixture block a and fixture block b like this during erection bolt on fixture block a, make test effect better, the result is more accurate.
As preferably, described through hole is an arc surface near described pinching end one side, and opposite side is a rectangular surfaces.In through hole, form arc transiting surface like this, be difficult for producing stress and concentrate, prolong the anchor clamps life-span.
As preferably, the transitional region of described installation end and pinching end is provided with circular arc chamfering.Be difficult for like this producing that stress is concentrated and the damage that causes anchor clamps in the transitional region of installation end and pinching end.
The utility model does not need to take off fixture block a from testing machine when changing the test bolt, has saved the operation of installing and adjusting, and improved test efficiency, and the site of action bearing capacity of fixture block a and fixture block b and testing machine is strong, is difficult for being broken.The utility model can be made according to the model of different bolts in addition, and is applied widely.
