The utility model has the following contents:
the utility model aims at providing an anchor clamps suitable for controllable temperature friction wear testing machine, this anchor clamps can realize cable oil pipe friction wear performance test of material under the high temperature when carrying out the friction wear test and can realize the friction wear performance test that has the grit under the lubricated state again, and convenient to detach can recycle.
The utility model aims at solving through the following technical scheme: a clamp suitable for a temperature-controllable friction wear testing machine comprises an upper sample clamp, a lower sample clamp, a loading device and a coupler, wherein a brass heating plate is installed inside the upper sample clamp, the upper sample clamp is connected with the upper part of the friction wear testing machine through the loading device, and loading pressure is set through the loading device; the lower sample clamp is arranged on the coupler, a circular groove is formed in the bottom of the lower sample clamp, a brass heating plate is loaded in the circular groove, two rectangular grooves are formed in the top of the lower sample clamp, four fastening bolts are arranged on the periphery of the two rectangular grooves, and a positioning bolt is arranged on the outer side of each rectangular groove.
The beneficial effects of the utility model reside in that:
1. the utility model discloses an anchor clamps are through anchor clamps the inside installation brass hot plate about, heat the sample more than 300 degrees, utilize temperature controller control temperature interval. The outer circumference of the lower clamp is provided with the high polymer material sleeve, crude oil and gravel are added into the sleeve, the upper clamp and the lower clamp are immersed, and the influence of parameters such as crude oil flow velocity, gravel size and sand content on the abrasion performance of the cable/oil pipe can be tested.
2. The utility model discloses an anchor clamps loading and unloading are free, more make things convenient for the staff to operate, can recycle the cable oil pipe of different specifications moreover, and the utilization efficiency is high.

Description of reference numerals: the test device comprises a lower sample clamp 1, a rectangular groove 2, a circular groove 3, a positioning bolt 4, a fastening bolt 5, a loading device 6, an upper sample clamp 7, an upper sample 8, a circular hole 9, a lower sample 10, a sleeve 11 and a coupler 12.
The specific implementation mode is as follows:
the present invention will be described in further detail with reference to specific embodiments. The clamp suitable for the controllable-temperature friction wear testing machine comprises an upper sample clamp 7, a lower sample clamp 1, a loading device 6 and a coupler 12, wherein a brass heating plate is installed inside the upper sample clamp 7, the upper sample clamp 7 is connected with the upper part of the friction wear testing machine through the loading device 6, and loading pressure is set through the loading device 6; lower sample anchor clamps 1 is installed on shaft coupling 12, and open the bottom of lower sample anchor clamps 1 has circular recess 3, and the brass hot plate is loaded in circular recess 3, and open at the top of lower sample anchor clamps 1 has two rectangle recesses 2, and two rectangle recesses 2 are opened all around have four fastening bolt 5, and a positioning bolt 4 has respectively been opened to the outside.
The device of the utility model is adopted to test the friction and wear performance of the cable and the oil pipe under high temperature, firstly, the oil pipe to be tested is pressed into a flat sample along the circumferential direction, a round hole 9 is arranged at the center of the flat sample, and the flat sample (namely an upper sample 8) is fixed on an upper sample clamp 7 through the round hole 9; secondly, in order to achieve the purpose of friction abrasion between the cable sheath or the steel wire arranged in the cable and a flat plate sample (namely an upper sample 8), the cable is pre-bent before the test, the length of a rectangular groove 2 used for storing the cable (namely a lower sample 10) is selected to be 86mm, the cable is placed in the rectangular groove 2 during assembly, and two ends of the cable are fixed on a fastening bolt 5 by using the steel wire with the diameter of 0.3mm so as to keep the in-situ performance of the cable in the abrasion test process; finally, an upper sample holder 7 on which the flat plate sample is mounted is connected to the upper part of the frictional wear tester via a loading device 6, and a loading pressure is set by the loading device 6.
