The purpose of this invention is to provide a kind of reciprocating surface wear testing machine with two cover abrasion test devices, it can carry out two groups of wear tests simultaneously, to shorten total test period, and make two groups of tests have identical experimental situation and condition, have higher precision and better repeatability to guarantee experiment.In order to solve the eccentric wear problem of sample, the present invention adopts a kind of special entity to guarantee that the sample contact is good up and down in last specimen holder, can eliminate sample eccentric wear problem.

The present invention is achieved through the following technical solutions, reciprocating surface wear testing machine by frame [1], motor [2], gear case [3], by handle linkage assembly, guide rail [30], down sample coaster [28], go up specimen holder [I], fixture supports frame [16], lever load maintainer and form.This testing machine parallel symmetry on the frame installed the identical toggle of two nested structures, guide rail, down the sample coaster, on specimen holder, fixture supports frame, lever load maintainer and spiral sphere carrier head [II].

Two row's balls [29] are housed below the following sample coaster [28] of reciprocating surface wear testing machine, evenly separate with plate shape ball retainer [14] between each ball, and be installed on the guide rail [30] with two rows, half garden arc groove [a].

Be equipped with one on the last sample holder in last specimen holder [I] concrete [26] from whole position Cylinder [32], a plane [b] with parallel axes is arranged on this Cylinder.

Spiral sphere carrier head [II] is made up of steel ball [20], gland [21], the screw rod [22] that has garden arc groove [C], and screw rod is by being screwed at the top of sample holder concrete [I].

Detection table [18] is housed on the loading head in the lever load maintainer [19].

The guiding theory of the technology of the present invention solution is: rack-mounted motor passes through belt gear, gear case is passed in motion, through passing motion to two cover crank linkage assemblys of parallel installation after the gear change, the rotation of motor is become the linear reciprocating motion of following sample.Last sample is contained in the specimen holder, maintains static.Utilize the lever load maintainer with load by loading head, steel ball, spiral sphere carrier head, go up sample holder and specifically be applied on the sample, sample contact up and down, through sample several times linear reciprocating motion down, sample produces and weares and teares up and down.By change in size or the weight change of measuring upper and lower sample, just know the wear extent of sample up and down.In last specimen holder, adopt whole certainly Cylinder mechanism, guaranteed that the sample contact is all right up and down, eliminated the eccentric wear phenomenon.For reducing the frictional resistance in the motion, will play sample coaster and lower guideway contact portion and side that rolling body all has been installed, make motion flexible, light.

Effect of the present invention is to utilize two groups of experimental provisions that structure is identical provided by the invention, can carry out two groups of experiments simultaneously on a machine, promptly as many as two testing machine work.Can shorten experimental period greatly, because of experimental situation (temperature, humidity, voltage etc.) is identical, the experimental result error is little, precision height, favorable repeatability.Adopt rolling friction to replace original sliding friction between following sample coaster and the guide rail, the resistance of motion is little, and it is little to generate heat, flexible movements, light, testing machine long service life.
