Problems solved by technology

[0003] At the same time, when the traditional friction and wear testing machine applies pressure to the two samples, it is easy to cause the sample to be deflected, and the bonding surface of the two samples cannot be guaranteed to be a plane, or even the contact surface of the two samples is A line, so this also seriously reduces

Example Embodiment

[0022] Combine Figure 1 to Figure 6 , To further explain the present invention:

[0023] A multi-head planar reciprocating friction and wear tester, including a workbench 10, on which a lower clamp 20 for fixing a sample to be tested is provided, and a movable crossbeam 40 is provided above the workbench 10, the movable crossbeam 40 The upper clamp 50 is used to clamp the upper sample to be tested. The adjusting mechanism adjusts the movable cross beam 40 to move up and down and makes the upper clamp 50 and the lower clamp 20 close to or away from each other. The movable cross beam 40 is horizontally overhanging and arranged There is an elastic plate 30, the plate surface of the elastic plate 30 is arranged horizontally, the upper clamp 50 is fixed on the overhanging end of the elastic plate 30, and the upper end of the upper clamp 50 is provided with a pressing head 70 which is vertical It moves back and forth in the upper clamp 50 and abuts or separates from the upper sample ...

Abstract

The invention relates to a multihead plane reciprocating friction wear testing machine. The multihead plane reciprocating friction wear testing machine comprises a worktable, wherein lower clamps forfixing lower to-be-tested samples are arranged on the worktable; a movable cross beam is arranged above the worktable; upper clamps are arranged on the movable cross beam; a mechanism adjusts the movable cross beam to vertically move and enables the upper clamps to be close to or separated from the corresponding lower lamps; elastic plates are horizontally arranged on the movable cross beam in a suspending manner; the plate surfaces of the elastic plates are horizontally arranged; the upper clamps are fixed at the suspending ends of the elastic plates; pressure applying heads are arranged at the upper ends of the upper clamps; a three-way force sensor is arranged on the lower clamps and is used for detecting applying pressure of the pressure applying heads; a driving mechanism drives the lower clamps to do reciprocating motion in the horizontal direction; the upper clamps are fixed at the ends of the elastic plates; when the pressure applying heads prop against upper to-be-tested samples, the upper to-be-tested samples can be always kept vertical, further friction surfaces of the upper to-be-tested samples and the lower to-be-tested samples are always planes, the constancy of the contact pressure of the friction surfaces is kept and data accuracy of a friction test is ensured.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a multi-head plane reciprocating friction and wear testing machine. Background technique [0002] The friction and wear test of the sample is to conduct an accelerated friction and wear test on the part of the workpiece or the prepared sample that actually faces the friction, so as to test its friction coefficient and wear rate curve in a short time, which is of great importance to the application research of the sample. to a more crucial role. In the actual operation of the friction and wear test, two samples to be tested are placed on the testing machine, and the surfaces to be tested of the two samples are bonded together, and one of the samples is pressurized by a pressurizing device, and pulled back and forth The sample, so as to realize the back and forth friction of two samples, under the set time and set pressure, record the friction coefficient and wear amount...
