Description
Technical Field
The utility model relates to a test device technical field, more specifically relate to a broken protecting against shock aligning device for test piece center and adjusting well at pneumatic cylinder center when breaking test.
Background
At present, the force measurement of test equipment mainly adopts two modes of a load sensor and a pressure sensor. The load sensor is mainly arranged between the loading hydraulic cylinder and the test piece connecting piece and is used for directly collecting the actual stress of the test piece; the pressure sensor mainly collects the pressure of a force application cavity of the loading hydraulic cylinder, then calculates the actual stress of the test piece through software, and the piston of the loading hydraulic cylinder is directly connected with the test piece connecting piece.
In order to ensure that the center of the test piece is automatically aligned with the center of the hydraulic cylinder during loading and eliminate errors of the test piece caused by coaxiality, a self-aligning device is generally required to be added between a test piece connecting piece and a load sensor (or a piston of the hydraulic cylinder), but when a test piece breakage test is carried out, the self-aligning device cannot effectively eliminate the impact of the broken test piece on test equipment, the impact generated by the broken test piece easily damages the load sensor (or the piston of the hydraulic cylinder), the collection precision and the service life of the load sensor are influenced (or oil leakage at the rod outlet end of the hydraulic cylinder is caused), and a serious person can damage the hydraulic cylinder and the test equipment.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: in order to solve the problem that the test piece can't be eliminated completely to the impact of test equipment to current aligning device, the utility model provides a broken protecting against shock aligning device.
The utility model discloses a realize above-mentioned purpose and specifically adopt following technical scheme:
the utility model provides a broken protecting against shock aligning device, is including establishing the load sensor at pneumatic cylinder piston lower extreme, the load sensor lower extreme is equipped with the sphere seat, sphere seat lower extreme is equipped with the bulb, the bulb lower extreme is equipped with the test piece connecting piece, the equipartition has a plurality of bolster between test piece connecting piece and the pneumatic cylinder piston lower extreme, the bolster encircles the setting of sphere seat circumference.
Further, the buffer is a damper.
The utility model has the advantages as follows:
1. the utility model has simple structure, the buffer parts are evenly distributed around the spherical seat, the gap between the spherical seat and the ball head can be eliminated, the realization of the aligning function is not influenced, when the test piece is subjected to the breaking test, the buffer parts can absorb the instantaneous impact force generated when the test piece is broken, and the load sensor is prevented from being influenced by the impact force;
2. in the test process, if the test piece center and the hydraulic cylinder center are not coaxial, the test piece center and the hydraulic cylinder center can flexibly swing within a certain range through the ball head and the test piece connecting plate, so that the coaxiality error can be corrected, and the test piece center and the hydraulic cylinder center can be automatically aligned.
