Embodiment

[0066] figure 1 shows a perspective view of an implementation of the fretting test device 001 of the embodiment of the present invention; figure 2 for figure 1 Frontal view of part of the structure; image 3 for figure 1 side view.

[0067] See figure 1 (for coordination see figure 2 , image 3 ), the fretting test device 001 in this embodiment includes: a frame 100 , a sample stage 200 , a fretting device 300 , a load applying device 400 and a friction measuring device 500 .

[0068] Cooperate see Figure 4 , wherein the sample stage 200 is slidably fitted to the frame 100 along the first linear direction Y1, and the sample stage 200 includes a sample holder 201 for holding the test sample S2. The form of the chuck of the sample holder 201 can be set in various forms, and can be determined according to the shape or other physical and chemical properties of the test sample S2 to be clamped. For example, for a circular test sample S2, the clamping head of the sample ...

Abstract

The invention relates to the field of testing devices, and provides a fine motion device and a fine motion testing device in order to solve the problem that an existing fine motion device cannot stably and precisely adjust and provide reciprocating fine motions. The fine motion device comprises a fine motion generator and a transmission structure. The fine motion generated is constructed to be capable of generating reciprocating fine motion in the first straight line direction. The transmission structure comprises a fixed part connected to the fine motion generator in the first straight line direction, and a movable part hinged to the outer end of the fixed part. The outer end of the movable part is used for installing a friction piece and transmitting the reciprocating fine motions to a reciprocating fine motion output end of the friction piece. A hinge rotating shaft between the movable part and the fixed part extends in the second straight line direction perpendicular to the first straight line direction. The fine motion device has the advantage of being capable of stably and precisely adjusting and providing reciprocating fine motions.

Description

technical field [0001] The invention relates to the field of test devices, in particular to a micro-motion device and a micro-motion test device. Background technique [0002] The fretting test includes tests for simulating and / or studying the damage mechanism of mutual fretting friction between objects, which requires reciprocating fretting of the friction part on the surface of the sample sample. [0003] However, the existing micro-motion devices cannot stably and accurately adjust and provide the reciprocating micro-motion. Contents of the invention [0004] The present invention aims to provide a micro-motion device to solve the problem that the existing micro-motion device cannot adjust and provide reciprocating micro-motion stably and accurately. [0005] Another object of the present invention is to provide a fretting test device provided with the above-mentioned fretting device. [0006] Embodiments of the present invention are achieved like this: [0007] A mi...
