Description

The compression of gasket material and resiliency test machine

The utility model relates to a kind of compression and resiliency test device of gasket material, specifically, relates to a kind of compression and resiliency test machine of small-sized hand-operated formula gasket material.

The compression of gasket seal material or usually said " creep " property and rebound resilience or what is called " compressed residual distortion " under long-term stress are the important performances of gasket material, and they are related to the quality of the sealing property of pad.Test to these performances is the important means that guarantees the pad quality.

From the interrelated data of consulting, present domestic manufacturer still impotentia carries out the test of these parameters, has only colleges and universities of several family and research institute can carry out the test of this respect, and tracing it to its cause is because present domestic this kind product that uses is the fluid pressure type loading and unloading, cost is very high, and testing expense is more expensive.

The purpose of this utility model is to design that a kind of volume is little, simple in structure, good reliability, easy to operate, measuring accuracy is higher, load and unload carried convenient, processing and easy for installation, cost is lower and the compression of the small-sized hand-operated formula gasket material of the extensive versatility of tool and resiliency test machine.

Realize the technical solution of the utility model:

The compression of small-sized gasket material provided by the utility model and resiliency test machine be one manually the device, need not be equipped with power system, comprise: framework, load bar, inner chamber are provided with the overcoat of gathering sill, the interior cover of spiral, elevating screws cover, resilience guide rod, standard testing pressure head, spacer base, counterweight base and the displacement measurement instrument that the outside is provided with orienting lug;

By Fig. 1, Fig. 2, Fig. 3 and Fig. 4 as seen, the utility model comprises:

One by upper support bar cover 106, middle cramp bar cover 107 and lower support bar cover 108, go up force bearing plate 102, in a force bearing plate 103, in two force bearing plates 104 and following force bearing plate 105 cooperatively interact overcoat 6, outside that the quadrilateral frame 1, load bar 7, the inner chamber that constitute be provided with gathering sill 601 be provided with overlap 2 in the spiral of orienting lug 201, elevating screws overlaps 4, resilience guide rod 8, standard testing pressure head 9, spacer base 10, counterweight base 3 and displacement measurement instrument 12;

Said 102 of the force bearing plates gone up are on upper support bar cover 106, in 103 of force bearing plates on middle cramp bar cover 107, in 104 of two force bearing plates on lower support bar cover 108,105 of following force bearing plates and pass each force bearing plate and the integrally-built connection of bar cover realization with adding thru-bolt 101 below lower support bar cover 108.So, as long as the length enough accuracy and the end face of each cramp bar are enough parallel, can guarantee that promptly each force bearing plate has enough depth of parallelisms; Force bearing plate 102 in the adjusting, in a force bearing plate 103, in relative position between two force bearing plates 104 and the following force bearing plate 105, promptly can adjust the right alignment between resilience guide rod 8 and the load bar 7.

Cover 2 is enclosed within the top of load bar 7 slidably in the said spiral, overcoat 6 is enclosed within the outside of cover 2 in the spiral, and be fixed on the force bearing plate 102, orienting lug 201 in the spiral on the cover 2 embeds in the gathering sill 601 of overcoat 6, elevating screws cover 4 is arranged on the top of overcoat 6, and the internal thread of elevating screws cover 4 is meshed with the external thread of cover 2 in the spiral;

Said counterweight base 3 is fixed on the top of load bar 7;

Said resilience guide rod 8 is arranged on the below of load bar 7, in passing a force bearing plate 103 and in two force bearing plates 104, position, and coaxial, and can move up and down with load bar 7;

Be preferably in middle orienting sleeve 110 is set on the force bearing plate 103, in orienting sleeve 111 down is set on two force bearing plates 104, orienting sleeve 110 and following orienting sleeve 111 during load bar 6, resilience guide rod 8 pass dock mutually, to guarantee load bar 6, right alignment when resilience guide rod 8 moves up and down.

During said displacement measurement instrument 12 is fixing on the force bearing plate 103, and match with block 11 on being fixed on resilience guide rod 8, displacement measurement instrument 12 can adopt conventional dial gauge or displacement transducer;

Said standard testing pressure head 9 is arranged on the below of resilience guide rod 8;

Spacer base 10 is arranged on the below of standard testing pressure head 9, and is fixed on down on the force bearing plate 105.

As shown in Figure 1, for preventing the landing of counterweight, a counterweight backstay 301 can be set at the center of counterweight base 3;

Between elevating screws cover 4 and the spiral sleeve 6 rolling bearing 5 is set,, makes rapid operation, on elevating screws cover 4, a handle 401 is set again, with the rotation of easy of rise screw-casing 4 to reduce sliding friction torque;

The utility model is to use like this:

Resilience guide rod 8 moves up, tested pad 13 is placed on the spacer base 10, can realize the installation of pad 13, counterweight 302 is added on the counterweight base 3, rotate elevating screws cover 4 then, the interior cover 2 of spiral is moved down, thereby the weight of the counterweight 302 of loading all is carried on the load bar 7, and pass to pad 13 on the spacer base 10 by resilience guide rod 8 and standard testing pressure head 9, write down the numerical value on the displacement testing tool 12 simultaneously;

Then, counter-rotation elevating screws cover 4, cover 2 moves up in the spiral, counterweight base 3 is driven on the load bar 7 to be moved, unload, resilience guide rod 8 and standard testing pressure head 9 are owing to pad 13 screen resiliences move up, and 11 of blocks that are fixed on the resilience guide rod 8 drive displacement measurement instrument 12, then can test out the correlation parameter of pad 13.

By the aforesaid operations process as seen, loading of the present utility model and unloading are finished by a combined helical mechanism, cover 2 is owing to the location cooperation of orienting lug 201 and gathering sill 601 can only move up and down and can not rotate in the spiral, moving up and down of cover 2 makes counterweight base 3 liftings of carrying counterweight 302 and realizes loading and unloading in the spiral, cover 2 does not produce rotation in the spiral in whole loading and uninstall process, counterweight base 3 is not rotated in lifting process, therefore can be to " creep " property and the rebound resilience or the what is called " compressed residual distortion " under long-term stress of pad, measure accurately, operate very simple and convenient.
