For achieving the above object, the technical scheme that the present invention adopts is:
A kind of contact wear fatigue experiment is used clamping device; Be arranged at and be used for the bar-shaped or plate tensile sample of clamping round metal on the single shaft fatigue testing machine and carry out the contact wear fatigue experiment; Described contact wear fatigue experiment comprises carrier, a pair of loading head carriage that is fixedly connected and is oppositely arranged with described carrier, slides and be arranged at a pair of loading head on the described loading head carriage respectively with clamping device; Described a pair of loading head is symmetrical set and the horizontal conllinear of its sliding axle; Symmetrical being provided with in both sides of each described sliding axle in the described loading head upper edge counterweight fixing pin that dangles; Be connected with wire rope on each described counterweight fixing pin that dangles, the other end of described wire rope is provided with counterweight; The wire rope and the counterweight that dangle the counterweight fixing pin and connect on it that are positioned at the homonymy of described sliding axle and are arranged at respectively on two described loading heads constitute one group of application of force assembly; In every group of described application of force assembly, the wire rope that the counterweight fixing pin connected of dangling on described loading head is walked around dangling the counterweight fixing pin and an end that is connected with described counterweight of described wire rope is vertically hung down on another described loading head.
Preferably, described loading head carriage is fixedly connected on the described carrier through set bolt.
Preferably, be applied with lubricating oil between described loading head carriage and the described loading head.
Preferably, each described horizontal coplane of counterweight fixing pin that dangles.
Preferably, the weight of each described counterweight is identical.
The present invention at first is positioned over it on single shaft fatigue testing machine in use, and sample is positioned between a pair of described loading head.Gravity through counterweight makes a pair of described loading head slide in opposition and described sample applied normal load in the horizontal direction.
Because the technique scheme utilization, the present invention compared with prior art has advantage: the present invention is simple in structure, easy to use, can match with the single shaft fatigue testing machine and accomplish the contact wear fatigue experiment.
Description of drawings
Accompanying drawing 1 is the synoptic diagram of contact wear fatigue experiment of the present invention with clamping device.
In the above accompanying drawing: 1, carrier; 2, loading head; 3, loading head carriage; 4, the counterweight fixing pin that dangles; 5, set bolt.
Embodiment
Below in conjunction with embodiment shown in the drawings the present invention is further described.
Embodiment one: shown in accompanying drawing 1.
A kind of contact wear fatigue experiment is used clamping device, is arranged to be used for the bar-shaped or plate tensile sample of clamping round metal on the single shaft fatigue testing machine and to carry out the contact wear fatigue experiment.
The contact wear fatigue experiment comprises the carrier 1 of rectangular framed structure, is fixedly connected through set bolt 5 with carrier 1 and a pair of loading head carriage 3 that is oppositely arranged, slides and be arranged at a pair of loading head 2 on the loading head carriage 3 respectively with clamping device.A pair of loading head 2 is symmetrical set and the horizontal conllinear of its sliding axle, and the relative end of loading head 2 has half-terete clamping part.In accompanying drawing 1, a pair of loading head 2 can slide along the left and right directions among the figure, the left and right directions horizontal distribution among its sliding axle and the edge figure.Loading head carriage 3 is held loading head 2 and is limited the moving direction of loading head 2, is applied with lubricating oil between loading head carriage 3 and the loading head 2 and is free to slide to guarantee it.
Symmetrical being provided with in both sides of each the loading head 2 upper edge sliding axle counterweight fixing pin 4 that dangles, each counterweight fixing pin 4 horizontal coplanes that dangle.Be connected with wire rope on each counterweight fixing pin 4 that dangles, the other end of wire rope is provided with the identical counterweight of weight.In the present embodiment, be provided with 4 dangle counterweight fixing pin 4 and four counterweights altogether.The wire rope and the counterweight that dangle counterweight fixing pin 4 and connect on it that are positioned at the homonymy of sliding axle and are arranged at respectively on two loading heads 2 constitute one group of application of force assembly, and promptly being seen two wire rope and counterweights that dangle counterweight fixing pin 4 and connect on it constitute one group of application of force assembly in the accompanying drawing 1.In every group of application of force assembly, the wire rope that counterweight fixing pin 4 connected of dangling on loading head 2 is walked around dangling counterweight fixing pin 4 and an end that is connected with counterweight of wire rope is vertically hung down on another loading head 2.
