Abstract

The invention discloses a self-adjusting clamp head for a macromolecular material multi-sample friction and abrasion tester for an oilfield, and belongs to the field of friction and abrasion testing devices. The self-adjusting clamp head comprises a transmission shaft, a cross shaft universal joint, an upper friction plate, a lower friction plate and a sleeve cylinder, wherein the upper end of the transmission shaft is fixedly connected with a rotary power shaft of the friction and abrasion tester, and the lower end of the transmission shaft is fixedly connected with the cross shaft universal joint; the lower end of the cross shaft universal joint is fixedly connected with the upper friction plate, a sample clamping hole is formed in the upper friction plate, and a sample is arranged in the sample clamping hole; the lower end of the lower friction plate is fixedly connected with a loading shaft, and the upper end of the lower friction plate is attached to the sample. The self-adjusting clamp head has the advantages that the requirement of friction and abrasion test on one or multiple macromolecular material samples with height size deviation at the oilfield site is met, and the loads on the samples are uniform; the structure is simple, and the testing efficiency is high.

Description

technical field [0001] The invention relates to a friction and wear test device, in particular to a self-adjusting chuck for an oil field multi-block friction and wear test machine for polymer materials. Background technique [0002] With the continuous development of oil fields, various polymer materials are more and more widely used in oil fields, such as HPPE lined pipes for anti-eccentric wear process, outsourcing sucker rods, etc. For oil fields using this material, friction performance tests must be carried out on materials provided by different manufacturers, and a friction and wear performance test report must be issued. At present, most of the commonly used friction testing machines are single test block tests, that is, each test can only complete the measurement of the friction and wear performance of a single test block, which cannot meet the increasing experimental task requirements of the oil field, and the efficiency is low; The polymer material test blocks ar...
