Abstract
The utility model discloses an axial loading device, including afterburning screw and adaptor, but afterburning screw spiral removes ground to be connected on the base lateral wall, and its threaded end center is connected with the adaptor, and the adaptor tip is provided with universal ball head, and universal ball head promotes the depression bar and presses. The utility model discloses an on the adaptor was transmitted the axial force to in afterburning screw rotation, the adaptor promoted the axial loading that the sample was realized to the depression bar, and universal ball head's contact can reduce the contact surface, prevented that the depression bar from rotating the influence to sample test data, improved the stability and the reliability of axial loading power greatly, improved experimental measuring accuracy, the utility model discloses still have simple structure, convenient operation characteristics swift and with low costs.
Description
Technical field
The utility model is related to a kind of axial loading device, belongs to high temperature and pressure experiment apparatus field.
Background technology
On multifunction test device, when axially loaded is carried out to sample, always occur that tested part rotates, test data
Inaccurate and unreliable, and the instantaneous change of the axial force loading easily appearance is big, wayward even variation, makes test data further
Inaccurate and unreliable, inconvenient operation.
Content of the invention
The technical problems to be solved in the utility model is：There is provided a kind of axial loading device, axially loaded power is stable, test
Data is more accurately and more reliable, to solve problems of the prior art.
The technical scheme that the utility model is taken is：A kind of axial loading device, including afterburning screw and adaptor, described
Afterburning screw can spiral be movably attached on base side wall, and its thread head center is connected with adaptor, and adaptor end sets
It is equipped with universal ball end, universal ball end promotes depression bar pressing.
Preferably, above-mentioned adaptor is Step Shaft, in the blind hole in the middle part of its little axle insertion reinforcing screw, and covers on little axle
It is connected to compression spring, compression spring one end is resisted against on afterburning screw end face, and its other end is resisted against in the big axial end of adaptor.
The beneficial effects of the utility model：Compared with prior art, the utility model passes through afterburning screw rotation by axially
Power is delivered on adaptor, and adaptor promotes depression bar to realize the axially loaded of sample, and the contact of universal ball end can reduce contact
Face, prevents the impact to sample testing data for the depression bar rotation, reduces the impact to axial load for the non axial component, greatly improve axle
To stability and the reliability of loading force, improve results precision, be placed between adaptor and afterburning screw using spring, because
The elastic buffer effect of spring, allows the axial force of loading to change slow, more uniformly, easily facilitates the change of controlled loading power,
Improve data test precision and testing reliability further, more convenient to operate easy, it is to avoid the test that instantaneous impact brings
Effect data is poor and unreliable and the damage of sensor, substantially increases safety in utilization, the utility model also has structure
It is simple and convenient to operate quick and low cost feature.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A close-up schematic view of Fig. 1；
Fig. 3 is the schematic top plan view of Fig. 1.
In figure：1- reinforcing screw, 2- adaptor, 3- base, the little axle of 4-, 5- universal ball end, 6- depression bar, 7- blind hole, 8- presses
Contracting spring.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the utility model.
As shown in Figure 1-Figure 3, a kind of axial loading device, including afterburning screw 1 and adaptor 2, afterburning screw 1 can spiral
It is movably attached on base 3 side wall, its thread head center is connected with adaptor 2, adaptor 2 is Step Shaft, its little axle 4 is inserted
Enter in the blind hole 7 at afterburning screw 1 middle part, blind hole 7 depth is more than little axle 4 length, and gap coordinates, and is socketed with pressure on little axle 4
Contracting spring 8, compression spring 8 one end is resisted against on afterburning screw 1 end face, and its other end is resisted against in the big axial end of afterburning screw 1,
Adaptor 2 end is provided with universal ball end 5, and universal ball end 5 promotes depression bar 6 to press, and afterburning screw 1 adopts T-shaped screw thread to load, and holds
Load power is big, and deformation is little, and T-shaped thread size is T30.
Use principle：As shown in figure 1, turning afterburning screw 1, spiral movement being changed into rectilinear movement, promotes depression bar 6 forward
Pressing, and sample opposite side is also equipped with depression bar against two depression bars are placed in realizes the axially loaded of sample in through hole.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art, in the technical scope that the utility model discloses, can readily occur in change
Or replace, all should cover within protection domain of the present utility model, therefore, protection domain of the present utility model should be with described power
The protection domain that profit requires is defined.
