A kind of tensile test machine clamp
Technical field
The invention belongs to automobile pipeline technical field of measurement and test, relate in particular to a kind of tensile test machine clamp.
Background technology
Orthodox car pipeline detects in operation, does not carry out the experiment that signal piping bears maximum pull, and the security of pipeline cannot guarantee.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of automobile pipeline maximum pull test experience, easy to adjust, reliable clamping, tensile test machine clamp that versatility is good of being applicable to.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of tensile test machine clamp, comprise chuck, described chuck is provided with dovetail groove, also comprise the pole being connected with chuck, in described dovetail groove, be provided with two briquettings, it is the inclined-plane suitable with dovetail groove side that two briquettings respectively have a side, and two relative faces of briquetting form clamping faces;
Described pole is provided with the guide groove of perforation, also comprises and stretches into pole push rod that can slippage in pole, and one end that described push rod stretches into pole is connected with pin, and the other end stretches in dovetail groove; Described pin stretches out described guide groove and can in guide groove, slide; One end that described push rod stretches into dovetail groove is connected with push pedal;
On described two briquettings, be respectively provided with a groove, described push pedal is inserted in groove and can in groove, be slided;
Described pole periphery is provided with external thread, also comprises and is threaded with pole and can promotes the rotating disk that pin slides in guide groove.
Described pole is provided with the connector being connected with puller system.
Between described push pedal and groove, be provided with lubricating oil, between described briquetting and dovetail groove, be provided with lubricating oil, between described pin and rotating disk, be provided with lubricating oil.
The clamping face of described fixture block is provided with groove.
Described rotating disk periphery is fixed with handle.
The invention has the advantages that, this fixture can be used for detecting on puller system the maximum pull that automobile pipeline can bear, and easy to adjust, reliable clamping, versatility are good, applicable to all kinds of pipelines.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of tensile test machine clamp of the present invention;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the partial enlarged drawing of Fig. 1;
Mark in above-mentioned figure is: 1, chuck, 11, dovetail groove, 2, pole, 21, guide groove, 3, push rod, 4, pin, 5, briquetting, 6, push pedal, 7, rotating disk, 8, handle, 10, connector.
Embodiment
Fig. 1 to Fig. 3 is the structural representation of a kind of tensile test machine clamp of the present invention, comprise chuck 1, chuck 1 is provided with dovetail groove 11, also comprise the pole 2 being connected with chuck 1, in dovetail groove 11, be provided with two briquettings 5, it is the inclined-plane suitable with dovetail groove 11 sides that two briquettings 5 respectively have a side, and two relative faces of briquetting 5 form clamping faces;
Pole 2 is provided with the guide groove 21 of perforation, also comprises and stretches into pole 2 can be at the push rod 3 of pole 2 interior slippages, and one end that push rod 3 stretches into pole 2 is connected with pin 4, and the other end stretches in dovetail groove 11; Pin 4 stretches out guide groove 21 also can be in the interior slip of guide groove 21; One end that push rod 3 stretches into dovetail groove 11 is connected with push pedal 6;
On two briquettings 5, be respectively provided with a groove, push pedal 6 is inserted in groove and can in groove, be slided;
Pole 2 peripheries are provided with external thread, also comprise and are threaded with pole 2 and can promote pin 4 at the rotating disk 7 of guide groove 21 interior slips.
Pole 2 is provided with the connector 9 being connected with puller system.By connector 9, fixture is connected on puller system.
Between push pedal 6 and groove, be provided with lubricating oil, between briquetting 5 and dovetail groove 11, be provided with lubricating oil, between pin 4 and rotating disk 7, be provided with lubricating oil.Fixture is difficult in the course of the work stuck.
The clamping face of fixture block is provided with groove.Groove is convenient to spacing pipeline.
Rotating disk 7 peripheries are fixed with handle 8, convenient operation rotating disk 7.
During use, rotary turnplate 7, rotating disk 7 promotes pin 4, drive push rod 3 to the interior slip of dovetail groove 11, under the effect of the pressing plate of push rod 3 ends, briquetting 5 moves downward, under the effect of the sidewall of dovetail groove 11, the distance between the clamping face of two briquettings 5 reduces, and plays clamping action.
Adopt after above-mentioned structure, this fixture can be used for detecting on puller system the maximum pull that automobile pipeline can bear, and easy to adjust, reliable clamping, versatility are good, applicable to all kinds of pipelines.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
