Abstract

The utility model discloses a handling device of a rubber compression permanent-deformation compression clamp, which relates to the technical field of rubber detection. The handling device comprises a lower plate, an upper plate and a stand column, wherein the upper plate is arranged above the lower plate and parallel to the lower plate; the stand column penetrates through the edges of the upper plate and the lower plate and is used for fixing the relative positions of the upper plate and the lower plate; the position, corresponding to three screws below the compression clamp, of the middle part of the lower plate is provided with a turnbuckle; the middle part of the upper plate is provided with a pressurizing device for pressurizing a compression plate. The handling device is novel in design, simple in structure, convenient to use and operate, and capable of being independently completed by one person, and the labor intensity of the employees can be alleviated.

Description

A kind of handler of rubber compression set compression clamp

Technical field

The utility model relates to rubber detection technique technical field, specifically a kind of handler of rubber compression set compression clamp.

Background technology

While carrying out rubber permanent compression test by national standard < < GB/T7759 vulcanized rubber, thermoplastic elastomer normal temperature, high temperature and low temperature lower compression permanent strain mensuration > > at present, the compression clamp that uses as depicted in figs. 1 and 2, mainly comprise 2,54 stop 4(2 of 4 compressive plates that are parallel to each other that stack large group of A, B, 9 of every group of 3 kinds of different-thickness) and 3 fastener screws 1 form, compressive plate requires smooth surface, even thickness.

Process of the test is first the sample of having measured thickness to be put into compression clamp middle (every layer of sample), by three screw tightenings until between compressive plate distance equal the thickness of stop, compression clamp integral body is put into certain environment (temperature, medium, humidity) (as baking oven etc.) to be tested, after test duration arrives, take out compression clamp, screw is unclamped, from compression clamp, take out sample, park certain hour, measure again the thickness after sample compression, the compression set that can calculate rubber in substitution correlation formula.

In process of the test, tightening and unclamping screw is generally by manual operation, in order to keep uniformity, can not disposablely tighten and unclamp on earth, require three screws to loop, conventionally at least carry out 2～3 above circulations, if 1～2 screw is first tightened or is unclamped on earth, other screw operation is very inconvenient and inhomogeneous, when being pressed to the later stage and just having started to unclamp, screw often produces transfer simultaneously, this will use wrench (survivor of a murder attempt's plate, stiff, quincuncial plate, interior hexagonal plate, cage plate etc.) will be below spiral shell head-clamp firmly do not allow its transfer, thereby people's inconvenient operation, normally 2 people carry out compounding practice, and be pressed onto and finally and just start there is certain labour intensity when loosening.

Summary of the invention

For existing practical problems in above-mentioned, the utility model provides a kind of handler of rubber compression set compression clamp.

The utility model is achieved through the following technical solutions: a kind of handler of rubber compression set compression clamp, comprises lower plate; Be positioned at lower plate top the upper plate parallel with lower plate; Through upper and lower plates edge, be used for the fixedly column of upper and lower plates relative position; Below the described corresponding compression clamp in lower plate middle part, on the position of three screws, offer thread; At described upper plate middle part, be provided with for the pressue device to compressive plate pressurization.

It is further: described pressue device comprises vertically the threaded rod through upper plate middle part; Described threaded rod upper end is fixed with the afterburning dish of level.

Described lower plate and upper plate are circular or other analogous shape, and its edge evenly has three through holes.

Described column is through the through hole at upper and lower plates edge, and two ends are fixed by nut.

During use, the sample of measuring thickness is put into compression clamp, first tentatively screw is compressed by hand, again compression clamp is put into this device, and make the screw terminal below compression clamp enter into thread (choosing thread according to compression clamp screw terminal specification in advance), using pressue device to compress compression clamp puts in place, by hand nut is turned to tight again, with wrench (survivor of a murder attempt, stiff hand, double off-set spanners, wrench, interior angle wrench) (selecting according to nut), nut is stepped up to make that wherein stop is inactive, finally unclamp hold down gag, take out compression clamp.By test condition, test.

When test period is unclamped compression clamp taking-up sample to needs, compression clamp is put into this device, to good thread below, first with pressue device, compression clamp is compressed, with wrench, nut is unclamped again, after three nuts exit entirely, unclamp pressue device, take out compression clamp, finally take off clamping plate, thereby taking-up sample, while parking on request one section after, measure thickness.

The utility model is novel in design, features simple structure, use easy to operate, can people's complete independently, reduce employee's labour intensity.
