Abstract
The utility model discloses a tensile testing hook device. The angle of a hook can be directly adjusted under the condition that a clamping head of a tensile testing machine is not required to be opened or clamped, and the defect that time and labor consumption is high because the angle of the conventional tensile testing hook is adjusted under the condition that the clamping head of the tensile testing machine is needed to be opened and clamped is overcome. The tensile testing hook device comprises a body, wherein a connecting groove and a limiting groove communicated with the connecting groove are formed on the body; a connecting head is arranged at one end of the body; a clamping handle is arranged on the connecting head; the limiting groove penetrates through the other end of the body; a hook is arranged in the connecting groove and comprises a hook body and a hook head which are connected through a transition section; the transition section is attached to and rotatably connected with the limiting groove; and the hook head stretches out of the body. The tensile testing hook device is applied to occasions where the conventional tensile testing hook device is applied, and has the advantages that the angle of the hook can be directly adjusted, force provided by the tensile testing machine can be well transferred to an object to be tested, and the like.
Description
Technical field
The utility model relates to a kind of test fixture, relates in particular to the hooking device that a kind of tension test is used.
Background technology
Glue class shear strength test is a kind of of tension test, and it is that the two ends of object that two sections glue is connected are separately fixed on the anchor clamps of two chucks of cupping machine, then carries out the fail in tension test, and hook is more common a kind of of such anchor clamps.Two hook ends are clipped in cupping machine up and down on two chucks, and the hook front end can be used for catching on the measured object two ends.Yet glue class shear strength test is obstructed and other tension tests, and its measured object can not reverse, and destroys otherwise will cause in advance, and is therefore very high to the angle requirement of hook, must guarantee that the measured object that catches on can not be subject to torsion.The hooking device that existing tension test is used, when two hooks up and down can not be in the situation that when not reversing measured object and tangling measured object, must utilize the chuck of driven by motor cupping machine to open by the operation control knob, operating personnel's Rotary hanging hook angle, with the angular adjustment between two hooks up and down to measured object being hung over up and down on two hooks and the position that can not twist, recycling motor clamping collet, because cupping machine is the larger equipment of volume, open, clamp the chuck of cupping machine, by driven by motor and comparatively slow, therefore adjusting the hook angle wastes time and energy without needs.
China Patent Publication No. CN102258317A, open day on November 30th, 2011, the name of invention is called a kind of hook, this application case discloses a kind of hook, it comprises hook head portions, link rod part and hook district, are connected a kind of material and connect and make an integral body in described hook head portions, link rod part and hook district, front end in the hook district is set up catching groove, the junction of hook head portions and connecting link is designed with bevel edge, the radian of bevel edge is that 60 degree are to 80 degree, link rod part is provided with the bending type transition face with the hook interval, and hook head portions is cylindrical slide block.If its weak point is still the angle that will adjust hook, needing wastes time and energy through opening, clamp the process of tension test machine grip holder.
The utility model content
The utility model has overcome when existing tension test is adjusted angle with hook need pass through the process of opening, clamp the tension test machine grip holder, cause the deficiency that wastes time and energy, provide a kind of and need just can directly not regulate the tension test hooking device of linking up with angle through the process of opening, clamp the tension test machine grip holder.
The utility model is achieved through the following technical solutions:
A kind of tension test hooking device, comprise body, the stopper slot that described body is provided with link slot, is communicated with link slot, described body one end is provided with connector, described connector is provided with grip shank, described stopper slot runs through the body other end, be provided with hook in the described link slot, described hook comprises Hook, gib head, described Hook is connected by transition section with gib head, described transition section and stopper slot are fitted, and described transition section and stopper slot are rotationally connected, and described gib head stretches out originally external.Link slot is used for holding Hook, and stopper slot is used for holding transition section, and stopper slot also has the prevention hook and drops out this external function.Transition section and stopper slot are rotationally connected, therefore when needs are regulated the hook angle, need only hold and link up with rotation, make hook on upper and lower two chucks of cupping machine go to correct position and get final product, need not through opening, clamp the process of tension test machine grip holder, operate very easy.
As preferably, described stopper slot comprises trough and groove body, and a diameter of described groove is greater than the diameter of groove body.The contact area of stopper slot and transition section is increased, and hook is more tight with being connected of body in the tension test process.
As preferably, described connector is cylindrical, and described connector is coaxial with link slot; Described grip shank is cylindrical, and described grip shank is coaxial with connector.The chuck of cupping machine is clamped connector, and to the power of a vertical direction of its effect, connector, link slot, grip shank be coaxial to be guaranteed can not produce in the transmittance process of this acting force the component of other directions to make the process of the test efficient stable in process of the test.
As preferably, described Hook is provided with the head that reclines, and the described head that reclines is annular, and the described head that reclines contacts with body internal surface, and a described side that reclines is provided with anti-skidding projection.The head that reclines contact with body internal surface and there is anti-skidding projection a side that reclines, makes the friction that reclines between head and the body enough large, make link up with in the process of the test and body between difficultly slide the stability of warranty test process.
As preferably, the minimum point of described gib head is on the grip shank axis.Make the power of the vertical direction that cupping machine provides pass to preferably measured object, make that measured object can not be subject to torsion in the process of the test.
Therefore, the beneficial effects of the utility model are: (1) need just can directly not regulate the hook angle through the process of opening, clamp the tension test machine grip holder; (2) power of the vertical direction that provides of cupping machine can pass to measured object preferably.
