Abstract
The invention discloses a kind of sleeping power protector for sensor that draws testing machine, comprise oil cylinder, piston, load sensor and moving beam, also comprise sphere pole, spherical bearing and dish spring, described sphere pole is placed in spherical bearing and packs into together in piston, spherical bearing is fixed on piston, described load sensor is provided with locating hole, and the locating hole of load sensor is connected to the rear end of moving beam by set bolt through sphere pole, and the front end of described moving beam is provided with dish spring; Described dish spring uses nut to be fixed on moving beam front end by dish spring installing rack. The present invention, after sample is disrumpent feelings, can effectively protect sensor, avoids sensor to be subject to impulsive force and destroys, simple in structure, dependable performance, the damage of having avoided the inertia force of the disrumpent feelings back piston of sample to cause sensor completely.
Description
Technical field
The present invention relates to a kind of sleeping power protector for sensor that draws testing machine, particularly a kind of on horizontal tensile testing machine the disrumpent feelings rear protective device to load sensor of sample.
Background technology
Along with scientific and technological progress and development, testing machine is as the equipment of the testing of materials and detection, obtain applying more and more widely, for some large-size horizontal tensile testing machines, need applied load sensor measurement test force, crouching draws testing machine to carry out tension test to material or member, sample is disrumpent feelings can produce larger impact load afterwards to sensor, affects the performance of sensor, reduces precision and even damages sensor, and large-tonnage power sensor is expensive, and replacement cost is high.
Summary of the invention
Technical problem to be solved by this invention is the defect for prior art, and a kind of protective device for power sensor on tensile testing machine is provided, and avoids the larger impact load that is subject to of sensor.
For solving this technical problem; the invention provides a kind of sleeping power protector for sensor that draws testing machine; comprise oil cylinder, piston, load sensor and moving beam; also comprise sphere pole, spherical bearing and dish spring; described sphere pole is placed in spherical bearing and packs into together in piston; spherical bearing is fixed on piston; described load sensor is provided with locating hole; the locating hole of load sensor is connected to the rear end of moving beam by set bolt through sphere pole, the front end of described moving beam is provided with dish spring.
Described dish spring uses nut to be fixed on moving beam front end by dish spring installing rack.
Beneficial effect: the present invention, after sample is disrumpent feelings, can effectively protect sensor, avoids sensor to be subject to impulsive force and destroys, simple in structure, dependable performance, the damage of having avoided the inertia force of the disrumpent feelings back piston of sample to cause sensor completely.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is cross-sectional view of the present invention.
In figure: 1 nut, 2 dish springs, 3 sphere poles, 4 moving beams, 5 load sensors, 6 set bolts, 7 oil cylinders, 8. spherical bearing, 9 pistons.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 1 shows that structural representation of the present invention.
Figure 2 shows that cross-sectional view of the present invention.
The present invention includes oil cylinder 7, piston 9, load sensor 5 and moving beam 4, sphere pole 3, spherical bearing 8 and dish spring 2.
Described sphere pole 3 is placed in spherical bearing 8 and packs into together in piston 9, and spherical bearing 8 is fixed on piston 9.
Described load sensor 5 is provided with locating hole, and the locating hole of load sensor 5 is connected to the rear end of moving beam 4 by set bolt 6 through sphere pole 3.
The front end of described moving beam 4 is provided with dish spring 2.
Described dish spring 2 uses nut 1 to be fixed on moving beam 4 front ends by dish spring installing rack.
Test principle of the present invention and process: when tension test, under the effect of oil cylinder 7 interior hydraulic oil, promoting piston 9 moves forward, because sphere pole 3 and spherical bearing 8 pack in the piston 9 of testing machine, sphere pole 3 is connected with load sensor 5, load sensor 5 use set bolts 6 are fixed on moving beam 4, be equivalent to that piston 9 promotes load sensor 5 and moving beam 4 moves forward, when disrumpent feelings moment of sample, act on the pulling force pop-off on moving beam 4, sphere pole 3, load sensor 5 travels forward together with moving beam 4 under the effect of inertia force, the sphere pole 3 being connected with load sensor 5 and spherical bearing 8 are thrown off in time, now, the compression that the stressed generation of dish spring 2 is certain, dish spring 2 further reduces impact load suffered load sensor 5, play obvious cushioning effect, the be not hit destruction of power of protection load sensor 5, extend the service life of load sensor 5. the present invention has simple in structure, the advantage of dependable performance, the damage of having avoided the inertia force of the disrumpent feelings back piston of sample to cause sensor completely.
The above-mentioned embodiment of the present invention, just illustrates, and is not only, and change within the scope of the present invention all or that be equal in scope of the present invention is all surrounded by the present invention.
