Abstract

The utility model provides a torsion machine universal chuck, usually, install on the torsion machine, be used for the centre gripping screw, thereby conveniently detect the workman and carry out torque force testing to the screw, including being used for the preceding lip river clamp splice of living hugged closely with torsion machine front plate, a back lip river alive clamp splice that be used for with the torsion machine after splint hug closely, the preceding lip river clamp splice of living is a cuboid with back lip river alive clamp splice, it presss from both sides the position groove all to set up a plurality of openings not of uniform size on the front and back side of preceding live lip river clamp splice and back lip river alive clamp splice, the contained angle alpha that each opening pressed from both sides the position groove is 90. The utility model discloses the torsion machine universal chuck commonality is strong, low in manufacturing cost, clamping fast convenient, the centre gripping is firm, is difficult for appearing the phenomenon of skidding, accessible 90 not unidimensional openings press from both sides a position groove 3 and make up test from M2.0 -M8.0's various standard series and nonstandard screw when the screw of the different specifications of centre gripping.

Description

Torsion machine universal chuck

Technical field:

The utility model relates to a kind of frock clamp, is specifically that one is arranged on torsion machine, and for clamp screws, thus convenient detection workman carries out the torsion machine universal chuck of torsional test to screw.

Background technology:

Some manufacturers are when producing screw, a strict quality standard is had to control to it, torsional test is a very important mechanical performance index in screw test, if screw torsion is not up to standard, it will being caused also not tighten when screwing in screw hole just rupture, especially also often occurring when using electronic spiral shell batch operation causing personal injury because of screw extraction.All torsion testing machine can be used when carrying out torsional test to screw, but the fixture brought due to torsion testing machine is all standard serialization, a kind of fixture of specification can only test the screw of corresponding specification, the non-constant of versatility, torsional test cannot be carried out for the non-standard component that client has made to order at all, in addition, the manufacturing cost of above-mentioned fixture is higher, every quality of fit requires high, sometimes also there will be because two semicircle orifices cannot clamp completely and skidding occurs, directly affecting the accuracy of test data.

Utility model content:

The technical problems to be solved in the utility model is, provide a kind of highly versatile, low cost of manufacture, clamping quick and convenient, clamp firm, not easily there is the torsion machine universal chuck of skidding.

Technical solution of the present utility model is, there is provided a kind of torsion machine universal chuck with following structure: comprise for Lip river fixture block of living before being close to torsion machine front plate, for the Lip river rear alive fixture block be close to torsion machine rear plate, front Lip river alive fixture block and rear Lip river alive fixture block are a rectangular parallelepiped, the front and back sides of front Lip river alive fixture block and rear Lip river alive fixture block all offers multiple opening not of uniform size folder position groove, the angle α of each opening folder position groove is 90 °.

After adopting above structure, compared with prior art, the utility model torsion machine universal chuck has the following advantages: the utility model can only clamp a kind of specification screw half nahlock by two of original fixture is revised as two rectangular front Lip river fixture block and rear Lip river alive fixture blocks of living, and on the front and back sides of front Lip river alive fixture block and rear Lip river alive fixture block, offer multiple 90 ° of openings folder position grooves not of uniform size, test workman is by being undertaken combining the screw that can clamp multiple different size by 90 ° of opening folder position grooves of different size on front Lip river alive fixture block and rear Lip river alive fixture block, standard component and non-standard all can clamp, versatility is very strong, and low cost of manufacture, clamping gets up very quick and convenient, two relative 90 ° of openings folder position groove clamp screws are very firm, there will not be skidding, ensure that the accuracy of test data.

Accompanying drawing illustrates:

Fig. 1 is the plan structure schematic diagram of the utility model torsion machine universal chuck;

Fig. 2 be in the utility model torsion machine universal chuck front Lip river fixture block and the rear Lip river alive fixture block of living by perspective view during wherein two 90 ° of openings folder position grooves combinations.

Embodiment:

Below in conjunction with the drawings and specific embodiments, the utility model torsion machine universal chuck is described in further detail:

As depicted in figs. 1 and 2, in this embodiment, the utility model torsion machine universal chuck comprises for Lip river fixture block 2 of living before being close to torsion machine front plate, for the Lip river rear alive fixture block 1 be close to torsion machine rear plate, front Lip river alive fixture block 2 and rear Lip river alive fixture block 1 are a rectangular parallelepiped, the front and back sides of front Lip river alive fixture block 2 and rear Lip river alive fixture block 1 all offers multiple opening not of uniform size folder position groove 3, the angle α of each opening folder position groove 3 is 90 °.90 ° of opening folder position grooves 3 that in the utility model torsion machine universal chuck, front Lip river fixture block 2 of living is different with the front and back sides of rear Lip river alive fixture block 1 offering all altogether six opening sizes, 90 ° of opening folder position grooves 3 when clamping the screw of different size by different size combine, test the various standard series from M2.0-M8.0 and nonstandard screw, as long as Lip river fixture block just can be suitable for the torsional test making various screw just because of the utility model torsion machine universal chuck two pieces of multidigits are lived, so clamping is convenient, speed is fast, and this fixture makes simple, cost is low, be applicable to various torsion machine, do not need the spare unit doing all size.

Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.

Claims

1. a torsion machine universal chuck, it is characterized in that: comprise for Lip river fixture block (2) of living before being close to torsion machine front plate, for the Lip river rear alive fixture block (1) be close to torsion machine rear plate, front Lip river alive fixture block (2) and rear Lip river alive fixture block (1) are a rectangular parallelepiped, the front and back sides of front Lip river alive fixture block (2) and rear Lip river alive fixture block (1) all offers multiple opening not of uniform size folder position groove (3), the angle α of each opening folder position groove (3) is 90 °.
