One key factor of exactness height.Due to structure, the outward appearance difference of various samples, the particularity of clamp structure is formed.
With the development of science and technology, requirement more and more higher of all trades and professions to material causes new material constantly to occur, to fixture
Design is put forward higher requirement.If any product requirement, under 150N pulling force, closing in junction will not be threaded off, but portion big absolutely at present
Divide the limit that fixture can be tested to be below 100N, the test request of new product cannot be met, for this reason, it is necessary to design one kind
The fixture of larger pressure can be detected.In addition, the structure of existing fixture is complex, and the detection process of sample is more bothered.
Utility model content
In view of this, the purpose of this utility model is to provide device for testing tensile force, to solve sample detection process trouble, show
The technical problem for having the detection pressure of fixture less and existing.
This utility model solves above-mentioned technical problem by the following technical programs：
A kind of device for testing tensile force, including base, union joint, fixed seat, regulating part, connector, sensor and bearing,
Fixed seat and bearing are arranged on base, and regulating part is arranged in fixed seat, and sensor is arranged on bearing, and union joint leads to
Cross connector to connect on a sensor, and union joint can be moved horizontally on connector, union joint is near one end end of fixed seat
Face is provided with perforate.
The union joint is hollow rectangular structure.
The hollow space of the union joint is in " convex " type.
The connector includes nut and studs, and the two ends of studs connect sensor and union joint respectively,
Nut is arranged on the studs of union joint one end.
The regulating part is pivot pin.
The sensor is connected using screw I with bearing.
The bearing is connected using screw II with base (1).
The fixed seat is connected using screw III with base.
The using method of the fixture is：First sample to be tested is fixed in fixed seat with regulating part, and by union joint and
Sample to be tested is threadedly coupled, it is desirable to sample anterior-posterior horizontal, pulls sensor, connector and union joint, reads on sensor
Pulling force data, when it is to be tested reach acceptance value after, union joint is pulled down from sample to be tested, regulating part is pulled up.
The beneficial effects of the utility model are：Type shape and material of this utility model according to test standard and sample, root
The tension test fixture is designed according to the particularity of test method, the position weight by line of force and the power of sensor of sample
Close, specimen clamping is parallel before and after can ensureing, during doing experiment, sample breakpoint is good, and data discrete is good.By specimen clamping in folder
On tool, by pulling sensor, connector and union joint, it is possible to apply the power of 150N.It is capable of achieving by connecting header structure
Test assembly is easy to loading and unloading quick, and fixture overall structure is capable of achieving manual operation, and simple to operation quick, clamping is reliable, no
Skid.Fixture overall structure guarantee test is accurately safe and reliable.
