Abstract
The utility model relates to an anti-releasing chuck device for a tensile testing machine. The anti-releasing chuck device comprises two chucks which are symmetrically arranged along a vertical direction, wherein the two chucks are provided with dovetail grooves respectively; the dovetail grooves are internally provided with ladder-shaped slide blocks matched with the dovetail grooves. Known by the technical scheme, the chuck device provided by the utility model utilizes an inclined plane fastening principle; an experiment tensile force is converted into a test piece clamping force by relative movement of the ladder-shaped slide blocks and the dovetail grooves; the clamping force is synchronously increased along the increasing of the experiment tensile force so that the anti-releasing chuck device is prevented from sliding off and an abrasion condition does not exist without applying the force to other parts; the anti-releasing chuck device is reliably clamped and is convenient to use.
Description
Technical field
The utility model relates to a kind of cupping machine, is specifically related to a kind of cupping machine anti-dropping clamp head unit.
Background technology
At present, do in test for tensile strength on universal testing machine, applied chuck is generally templin chuck and opposite-compacting type chuck, structure relative complex, and its principle is to withstand two locking racks by projection or bolt etc. substantially, clamps experiment body.But in tension test process, the chuck of universal testing machine is in clamping test pieces work, and usually because projection wearing and tearing, " skidding ", " collapsing tooth " phenomenon, appear in bolt hole and the stressed damage of bolt silk tooth and holding force is declined, and experiment is affected.
Utility model content
The purpose of this utility model is to provide a kind of cupping machine anti-dropping clamp head unit, and this cartridge device can carry out gripped object fastening, simple operation, easy switching.
For achieving the above object, the utility model has adopted following technical scheme: comprise along symmetrically arranged two chucks of vertical, on two described chucks, offer respectively dovetail groove, be provided with the trapezoidal slide block matching with it in described dovetail groove.
Described dovetail groove is respectively equipped with toothed projections with the face that trapezoidal slide block matches.
As shown from the above technical solution, cartridge device of the present utility model utilizes the fastening principle in inclined-plane, by the relative motion of trapezoidal slide block and dovetail groove, convert experiment pulling force to test specimen holding force, along with the increase of experiment pulling force, clamping force synchronously increases, thereby prevent slippage, because not by the miscellaneous part application of force, so there is not abrasion condition, reliable clamping, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of cupping machine anti-dropping clamp head unit as shown in Figure 1, comprises along symmetrically arranged two chucks 1 of vertical, on two described chucks 1, offers respectively dovetail groove 2, is provided with the trapezoidal slide block 3 matching with it in described dovetail groove 2.
Further, dovetail groove 2 is respectively equipped with toothed projections with the face that trapezoidal slide block 3 matches.Toothed projections can increase the friction force of dovetail groove 2 and trapezoidal slide block 3.
During use, experiment body 4 is wound with one circuit and tested along two trapezoidal slide blocks 3.Because the utility model is the principle of utilizing inclined-plane fastening, by the relative motion of trapezoidal slide block and dovetail groove, convert experiment pulling force to test specimen holding force, increase along with experiment pulling force, synchronously increases clamping force, thereby prevents the appearance of the phenomenons such as slippage, because not by the miscellaneous part application of force, so there is not abrasion condition, reliable clamping, easy to use.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
Claims (2)
