Abstract
The utility model provides a two-way cylinder hydraulic universal testing machine, which comprises a test stand. A two-way cylinder is mounted in the middle of the test stand, two vertical screw rods are respectively mounted on two sides of the work stand and connected with a driving device, a lower beam is matched with the two screw rods in a threaded manner, an upper beam is fixed at the upper ends of the two screw rods, an upper clamp mounting seat is mounted on the lower portion of the lower beam, a lower clamp mounting seat is mounted on the upper portion of a two-way cylinder piston rod, and the upper clamp mounting seat is opposite to the lower clamp mounting seat in arrangement. The two-way cylinder hydraulic universal testing machine finishes tension and compression tests in the same space, thereby simplifying structure of the testing machine.
Description
Technical field
The utility model relates to a kind of testing machine, especially a kind of two-way cylinder electric-liquid type universal testing machine.
Background technology
At present, the electric-liquid type universal testing machine generally adopts unidirectional cylinder structure, and main frame is by support (in adorn main operating cylinder), compositions such as worktable, sill, screw mandrel, column, entablature.Worktable and entablature are connected into a rigid frame by column, and worktable is connected by a socket head cap screw with working piston.Like this, just form two work spaces, i.e. the stretching space of entablature and sill formation; The compression stroke that sill and worktable form.The adjustment of stretching space and compression stroke is by the realization that moves up and down of sill.During tension test, sample holder is between entablature and sill, and sill remains static, and test power is delivered to worktable by piston, is delivered to entablature by column from worktable again, by the anchor clamps tensile sample of entablature, reaches test objective again.During compression test, sample is placed on the compression clamp of worktable, and sill remains static, and test power is delivered to worktable by piston, utilizes the compression clamp of sill and worktable to test.This testing machine structure is comparatively complicated, and worktable, screw mandrel, column, entablature and sill all need be stressed when tension test, and stressed part is many.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of two-way cylinder electric-liquid type universal testing machine, and its tensile and compression test is all finished in a work space, has simplified testing machine structure.
In order to solve the problems of the technologies described above, the two-way cylinder electric-liquid type universal testing machine that the utility model provides, comprise worktable, two-way cylinder is housed in the middle of the described worktable, a vertical screw mandrel respectively is equipped with in described worktable both sides, described two rhizoid bars link to each other with drive unit, sill and described two rhizoid bar threaded engagement, entablature is fixed on described two rhizoid bar upper ends, last anchor clamps mount pad is contained in described sill bottom, the lower clamp mount pad is contained in described two-way cylinder piston rod top, and described upward anchor clamps mount pad and described lower clamp mount pad are over against setting.
Preferably, described sill and described going up between the anchor clamps mount pad are equipped with tension-compression sensor.
Preferably, described drive unit is a motor.
Preferably, described motor links to each other with described two rhizoid bars by chain drive system.
Two-way cylinder electric-liquid type universal testing machine of the present utility model, between sill and worktable, form a work space, tensile and compression test is all finished in this space, have only worktable, screw mandrel, sill stressed during work, can reduce the material of entablature and save worktable and entablature between column, simplified testing machine structure, stressed part when reducing test.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be specified.
As shown in Figure 1, two-way cylinder electric-liquid type universal testing machine of the present utility model, comprise worktable 1, two-way cylinder 2 is housed in the middle of the worktable 1, a vertical screw mandrel 3 respectively is equipped with in worktable 1 both sides, two rhizoid bars 3 link to each other with drive unit, sill 5 and two rhizoid bars, 3 threaded engagement, entablature 4 is fixed on two rhizoid bars, 3 upper ends, last anchor clamps mount pad 6 is contained in described sill 5 bottoms, lower clamp mount pad 7 is contained in described two-way cylinder 2 piston rod tops, and last anchor clamps mount pad 6 and described lower clamp mount pad 7 also are equipped with tension-compression sensor 8 over against setting between sill 5 and the last anchor clamps mount pad 6.
Drive unit is a motor 9, and motor links to each other with two rhizoid bars by chain drive system.
During test, at first control motor and rotate, drive sprocket rotation, drive two rhizoid bars by chain and rotate, sill is moved up and down, to adjust test space.After adjusting test space according to the test specimen situation, anchor clamps are installed to anchor clamps mount pad and lower clamp mount pad, test specimen is clipped on the anchor clamps, it is static that sill keeps, and controls hydraulic circuit then, applies test power by the two-way cylinder piston, piston moves upward, then carry out compression test, piston moves downward, and then carries out tension test.
Two-way cylinder electric-liquid type universal testing machine of the present utility model, between sill and worktable, form a work space, in this work space, both can carry out tension test, also can carry out compression test, this testing machine has only worktable, screw mandrel, sill stressed, can reduce the material of entablature and save worktable and entablature between column, simplified testing machine structure, stressed part when reducing test.
More than just utility model has been carried out exemplary explanation, specific implementation of the present utility model is not limited thereto.The insubstantial modifications that any employing design of the present utility model and technical scheme are carried out is all within protection domain of the present utility model.
