Abstract
The invention discloses a force sensor protecting device of a horizontal tension tester. The force sensor protecting device comprises an oil cylinder, a piston, a load sensor and a movable beam, and further comprises a spherical supporting rod, a spherical supporting base and a disk spring, wherein the spherical supporting rod is arranged inside the spherical supporting base and the spherical supporting rod and the spherical supporting base are arranged inside the piston together; the spherical supporting base is fixed on the piston; a positioning hole is formed in the load sensor, penetrates through the spherical supporting rod, and is connected to the rear end of the movable beam by a fixing bolt; the disk spring is arranged at the front end of the movable beam and is fixed at the front end of the movable beam by a disk spring installation frame through a nut. After a test sample is broken, the force sensor protecting device disclosed by the invention can effectively protect the sensor and prevent the sensor from being damaged due to impact force, is simple in structure and reliable in performance, and completely avoids damages of inertia force of the piston on the sensor after the test sample is broken.
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 material test and detection, obtain applying more and more widely, for some large-size horizontal tension testers, 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 matters to be solved by this invention is the defect for prior art, and a kind of protective device for power sensor on tension tester is provided, and avoids the larger impact load that is subject to of sensor.
For solving this technical matters; 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 pilot hole; the pilot hole of load sensor is connected to the rear end of moving beam through sphere pole by set bolt, the front end of described moving beam is provided with dish spring.
Described dish spring is used nut to be fixed on moving beam front end by dish spring erecting frame.
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 inertial force of the disrumpent feelings back piston of sample to cause sensor completely.
Accompanying drawing explanation
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.
Embodiment
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 pilot hole, and the pilot hole of load sensor 5 is connected to the rear end of moving beam 4 through sphere pole 3 by set bolt 6.
The front end of described moving beam 4 is provided with dish spring 2.
Described dish spring 2 is used nut 1 to be fixed on moving beam 4 front ends by dish spring erecting frame.
Test principle of the present invention and process: during 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, being equivalent to piston 9 promotion load sensors 5 and moving beam 4 moves forward, when sample disrumpent feelings moment, 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 inertial force, the sphere pole 3 being connected with load sensor 5 and spherical bearing 8 are thrown off in time, now, the compression deformation that the stressed generation of dish spring 2 is certain, dish spring 2 further reduces the suffered impact load of load sensor 5, play obvious buffer action, the be not hit destruction of power of protection load sensor 5, extend the serviceable life of load sensor 5.The present invention has simple in structure, the advantage of dependable performance, the damage of having avoided the inertial 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.
