Abstract
Description
The invention belongs to reciprocating motion type surface wear testing machine field.
Reciprocating surface wear testing machine can be used for simulating the to-and-fro movement and the plane contact friction wearing and tearing working condition of actual part, to the surface coating of part material itself or material, test evaluation as the friction and wear behavior of coating, coating or thermal treatment layer etc.Existing reciprocating surface wear testing machine has only the test battery system, once can only carry out the M5-3 type of battery of tests such as Beijing Machine Tool Inst..In the time will carrying out two groups of contrast tests, will be divided into secondary does, it is long so not only to test the required time, and because of the variation of the environmental baseline of twice experiment, will cause the repeated bad of the wrong official post wear measurement of wear test result as temperature, humidity, voltage and variation.On existing abrasion tester, ubiquity eccentric wear problem, the mated condition of last sample and last specimen holder, as shown in Figure 1.Last procedure of detected sample generally requires grinding, parallels so can guarantee any two corresponding parallel planes of each sample.But the angle α on adjacent two planes, general being difficult to fits like a glove with the clamp body corresponding angles β (90 °) of last specimen holder, so when going up sample with holding screw fixedly the time, fit mutually in the side of last sample and the side of its clamp body, and upper and lower surface has produced certain inclination, therefore caused eccentric wear, made test figure untrue or repeated bad.
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.
Accompanying drawing 1 is the mated condition that goes up sample and specimen holder, wherein: and 1-holding screw, 2-upward sample holder is concrete, 3-upward samples, 4-following sample.
Accompanying drawing 2 is front views of reciprocating surface wear testing machine.
Accompanying drawing 3 is vertical views of reciprocating surface wear testing machine.
Accompanying drawing 4 is last specimen holder [I] and the spiral sphere carrier heads [II] that have from whole position device.
Be one embodiment of the present of invention below, be described with reference to the accompanying drawings details of the present invention.
The motor [2] that is contained on the frame [1] is passed to gear case [3] by belt gear [4] with motion, through behind the gear [5], [6], [7] speed change motion being passed to the crank axle [8] in the identical toggle of rack-mounted two nested structures of parallel symmetry, see accompanying drawing 2.Drive crankwheel [9] and rotate, through pin [10], connecting rod [11], drive slide block [12] and connecting link [13], following sample coaster [28] slide.Following sample [15] is contained in down in the sample coaster, two row's balls [29] are housed below the following sample coaster [28], evenly separate with plate shape retainer [14] between each ball, and be installed on the guide rail [30] with two rows, half garden arc groove [a], sample was done straight reciprocating motion under following sample coaster drove on guide rail.Last sample [27] is placed in the clamp body from whole position Cylinder [32] to be equipped with one on the last sample holder in the last specimen holder [I] concrete [26], by holding screw [31], whole certainly position Cylinder [32], be clamped in sample holder specifically in.Be milled with a plane [b] with parallel axes on the Cylinder of whole position, it can rotate along with the differing tilt angles α of last sample side, sees Fig. 4.Thereby guarantee that clamp body and clamped test specimen can well fit, eliminated the eccentric wear phenomenon.Steel ball [20] in the spiral sphere carrier head [II] is fixed on the carrier head by gland [21], and gland and carrier head can be with gluing together.The bottom of carrier head is screwed at the concrete top of sample holder.When doing experiment with the test specimen of differing heights, the spiral carrier head can be screwed in and screws out, make lever be transferred to level.The lever load maintainer is made up of lever [23], counterweight [24], lever balancing weight [17], loading head [19], and detection table [18] is housed on the loading head [19].In carrying out the wear test process, sample produces wearing and tearing up and down, and lever is descended, and this will make and detect meter reading and change, and can be used for the size of test samples wear extent.
