Abstract

The invention discloses a size-adjustable pressurizing, fixing and centering device and a centering method and belongs to the field of sample pretreatment. The centering device comprises a base and centering clamping plate units, centering guide grooves are arranged on the surface of the base, the two centering clamping plate units are slidably connected onto the centering guide grooves, two baffle plates are parallelly arranged on two sides of each centering guide groove, and fastening screws are arranged on the baffle plates. Certain contact pressure can be generated between sample pieces through the baffles and the fastening screws arranged on the two sides of the centering guide grooves, and good contact between the sample pieces is guaranteed; the two centering clamping plate units can do relative motion in the groove direction of the centering guide grooves, and therefore the centering clamping plate units can adapt to centering, pressurizing and fixing of sample pieces of different sizes by adjusting the sliding positions of the two centering clamping plate units on the centering guide grooves. The device is simple in structure, easy to operate and high in practicability.

Description

technical field [0001] The invention belongs to the field of sample pretreatment, and relates to the centering and pressurized fixing of a plurality of sample pieces, in particular to a size-adjustable pressurized and fixed centering device and a centering method. Background technique [0002] In mechanical experiments, especially in tensile tests, when the tensile piece is composed of two or more specimens, it is necessary to axially bond multiple specimens together before the experiment. During the bonding process, it is necessary to keep multiple specimens strictly centered at all times. If these specimens are not strictly centered, the experimental results will seriously deviate from the true value. Generally, in order to make the joint surfaces of the specimens tightly bonded, it is necessary to A contact pressure is provided at both ends of the sample, and it is required that these samples can be kept pressurized and centered without external interference for a long pe...
