A kind of tension tester clamp
Technical field
The invention belongs to automobile pipeline technical field of measurement and test, particularly relate to a kind of tension tester clamp.
Background technology
In orthodox car pipeline detection operation, do not carry out signal piping and bear the experiment of maximum pull, pipeline
Safety cannot ensure.
Summary of the invention
The technical problem to be solved is to provide one and is applicable to the detection of automobile pipeline maximum pull in fact
Test, the tension tester clamp that easy to adjust, reliable clamping, versatility are good.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of tensile testing machine folder
Tool, including chuck, described chuck is provided with dovetail groove, also includes the pole being connected with chuck, described dovetail
Being provided with two pieces of briquettings in groove, it is the inclined-plane suitable with dovetail groove side that two pieces of briquettings are respectively arranged with one side, two pieces
The face that briquetting is relative constitutes clamping face;
Described pole is provided with through guide groove, also include stretching into pole and can in pole the push rod of sliding,
Described push rod stretches into one end connection of pole has pin, the other end to stretch in dovetail groove;Described pin stretches out institute
State guide groove and can slide in guide groove;Described push rod stretches into one end connection of dovetail groove push pedal;
Being respectively provided with a groove on described two pieces of briquettings, described push pedal is inserted in groove and can slide in groove;
Described pole periphery is provided with external screw thread, also includes threadeding with pole and can promote pin in guide groove
The rotating disk slided.
Described pole is provided with the union joint being connected with puller system.
It is provided with lubricating oil between described push pedal and groove, between described briquetting and dovetail groove, is provided with lubricating oil, institute
State and between 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.
It is an advantage of the current invention that this fixture to can be used on puller system and detect the maximum that automobile pipeline can bear
Pulling force, easy to adjust, reliable clamping, versatility are good, are applicable to all kinds of pipeline.

Detailed description of the invention
Fig. 1 to Fig. 3 is the structural representation of a kind of tension tester clamp of the present invention, including chuck 1, chuck
1 is provided with dovetail groove 11, also includes the pole 2 being connected with chuck 1, is provided with two pieces of briquettings in dovetail groove 11
5, it is the inclined-plane suitable with dovetail groove 11 side that two pieces of briquettings 5 are respectively arranged with one side, and two pieces of briquettings 5 are relative
Face constitute clamping face;
Pole 2 is provided with through guide groove 21, also include stretching into pole 2 and can in pole 2 the pushing away of sliding
Bar 3, push rod 3 stretches into one end connection of pole 2 pin 4, and the other end stretches in dovetail groove 11;Pin 4
Stretch out guide groove 21 and can slide in guide groove 21;Push rod 3 stretches into one end connection of dovetail groove 11 push pedal 6;
Being respectively provided with a groove on two pieces of briquettings 5, push pedal 6 is inserted in groove and can slide in groove;
Pole 2 periphery is provided with external screw thread, also includes threadeding with pole 2 and can promote pin 4 at guide groove
The rotating disk 7 slided in 21.
Pole 2 is provided with the union joint 9 being connected with puller system.By union joint 9, fixture is connected to puller system
On.
It is provided with lubricating oil between push pedal 6 and groove, between briquetting 5 and dovetail groove 11, is provided with lubricating oil, pin
It is provided with lubricating oil between 4 and rotating disk 7.Fixture is made to be difficult in the course of the work stuck.
The clamping face of fixture block is provided with groove.Groove is easy to spacing pipeline.
Rotating disk 7 periphery is fixed with handle 8, it is simple to operation rotating disk 7.
During use, rotary turnplate 7, rotating disk 7 promotes pin 4, drives push rod 3 to slide in dovetail groove 11,
Under the effect of the pressing plate of push rod 3 end, briquetting 5 moves downward, under the effect of the sidewall of dovetail groove 11,
Distance between the clamping face of two pieces of briquettings 5 reduces, and plays clamping action.
After using above-mentioned structure, this fixture can be used for detecting on puller system the maximum that automobile pipeline can bear
Pulling force, easy to adjust, reliable clamping, versatility are good, are applicable to all kinds of pipeline.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by upper
State the restriction of mode, if the various unsubstantialities that the method design that have employed the present invention is carried out with technical scheme
Improvement, or the most improved design by the present invention and technical scheme directly apply to other occasion, all exists
Within protection scope of the present invention.
