Abstract
The utility model relates to a tensile test clamp, which includes draw machine jaws, a positioning sleeve, an adapter and a transmission pin, wherein the adapter is clamped in a draw machine lower jaw through the transmission pin; the positioning sleeve is sleeved at turbine parts from a shaft end; a protruding U-shaped gap at the shaft end is connected with the draw machine upper jaw for tensile test; and a circular hole is formed at the center of the bottom surface of the adapter, and a U-shaped opening is machined on upper surface. The tensile test clamp has a simple structure, is convenient to use and saves time; the adapter can be connected onto the draw machine through the transmission pin for frequent welded seam strength test of the turbine parts without the need of daily clamping and unloading; and the workpiece is not required to be specially machined, the turbine end can be directly placed below the U-shaped opening of the adapter, and the tensile test can be performed as long as the protruding U-shaped gap at the shaft end is connected with the draw machine upper jaw.
Description
Technical field
The utility model relates to a kind of tensile test fixture, specifically is used for the anchor clamps of booster turbine parts welding back weld strength test, belongs to material mechanical performance test fixture technical field.
Background technology
Present most of tensile test equipment all has strict demand to the size and dimension of workpiece, need work the work piece into standard component so that the reliability of clamping and warranty test data.This just requires the complex-shaped a series of processing of workpiece process that is difficult to clamping to reach the requirement of existing stretching clamp, labor manpower and materials.Must make a kind of special fixtures for complex-shaped workpiece, to satisfy the needs of this type workpiece extension test.Existing utility model tensile test fixture has following several kinds: the one, and the utility model name is called the tensile test fixture (patent No.: CN2911655Y) of the nonstandard sample of a kind of fragility; This sleeve clamp can effectively carry out the detection of tension test to various little hard brittle materials; But it is bigger for a diameter; Complex-shaped, an elongated sample can't be suitable for.(patent No.: CN200620022944X), it requires sample is the dumbbell shape standard sample, and for complex-shaped, irregular sample is inapplicable equally to also have a kind of patent to be called a kind of tensile test fixture.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point, thereby a kind of tensile test fixture is provided, and this jigs structure is simple, and is practical and convenient, is applicable to that an end area is difficult to clamping more greatly, the elongated workpiece weld strength tension test that is easy to clamping of an end.
The technical scheme that provides according to the utility model; A kind of tensile test fixture comprises drawing machine jaw, locating sleeve, adapter, power transmission pin; Said adapter through power transmission pin clamping in the drawing machine lower jaw; Locating sleeve is enclosed within on the turbine part from axle head, can carry out tension test after axle head stretches out U type breach and the upper jaw of drawing machine is connected.Said adapter bottom center is provided with circular hole, U type mouth of last plane processing.
Compared with present technology the utility model has the following advantages:
The utility model is simple in structure, and is easy to use, saves time; For often doing turbine part weld strength when test, can adapter be connected on the drawing machine through the power transmission pin, need not clamping every day, unloading; Workpiece need not through special processing, and turbine end directly is positioned over the U type mouth below of adapter, and axle head stretches out U type notch portion only to be needed just be connected with the drawing machine upper jaw and can carry out tension test.
Description of drawings
Fig. 1 is the utility model structure user mode figure.
Fig. 2 is the utility model adapter structural representation.
Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, comprise drawing machine jaw 1, locating sleeve 3, adapter 4, power transmission pin 5.
The utility model adapter 4 forms by after the four block plates welding, and wherein two blocks of steel are processed into earlier after the shape that requires in the design and other two block welding again up and down, need heat-treat after anchor clamps machine.Said adapter 4 bottom center are provided with circular hole 4-1, U type mouth 4-2 of last plane processing.Said adapter 4 through power transmission pin 5 clampings in drawing machine lower jaw 1; Power transmission pin 5 couples together adapter 4 and cupping machine lower jaw 1; Then locating sleeve 3 is enclosed within on the turbine part 2 from the workpiece axle head; Workpiece whirlpool end is placed on U type breach below, can carries out tension test after the workpiece spindle end parts is stretched out U type breach and the upper jaw of drawing machine is connected, the assurance workpiece is evenly stressed and vertically be clamped on the drawing machine.
