Five, embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
The reciprocating type femur friction wear testing machine of the utility model, it is made up of drawing and pressing type sensor 1, sensor mount pad 2, horizontal table 3, manual pulley 4, last specimen holder 5, following specimen holder dolly 8, electrical machine belt pulley 9, driving-belt 10, leading screw belt wheel 11, leading screw 12, travel switch 13, tester base 14, motor 15, motor cabinet 16, loading counterweight 18, counterweight positioning screw 17, slide block 19, V-arrangement track 20 and variable-frequence governor and computer data acquisition system.Following specimen holder dolly 8 is located on the worktable 3, and last specimen holder 5 rides over down specimen holder dolly 8 tops, and spatial vertical intersects mutually.Last specimen holder 5 is located in the V-type rail that is fixed in base 14 both sides, screw mandrel 12 by travel switch 13,11 transmissions of screw mandrel belt wheel is housed on the worktable 3, the block that is located on the worktable 3 is formed reciprocating reverse mechanism, sensor 1 is fixed on the worktable 3, is rigidly connected with following specimen holder dolly 8. Femur sample 6 and 7 is installed in respectively in upper and lower anchor clamps 5 and 8, and by counterweight 18, and the deadweight of slide block 19 and anchor clamps 5 loads friction pair, and the vertical contact of upper and lower sample is intersected under stress state.After opening motor 15, motor move through electrical machine belt pulley 9, driving-belt 10, leading screw belt wheel 11 turn-screws 12, about under the control of two travel switches 13, the to-and-fro movement that worktable 3 is produced on the horizontal direction, realize the reciprocating friction wearing and tearing of sample, variable-frequence governor can make the speed of reciprocating friction wearing and tearing adjustable continuously.Because between following specimen holder dolly 8 and the worktable 3 is rolling friction, frictional resistance is very little, therefore, the friction force between the sample directly affacts on the tension-compression sensor 1 by following specimen holder dolly 8, is gone out the size of friction force by the output electric signal measurement of sensor.Again because last sample can be along vertical V-arrangement track 20 upper and lower floating, thereby can adapt to the variation of the animal femur specimen surface shape of shape irregularity, so can in the variation of axis direction (horizontal reciprocating movement direction) height contact load or contact condition between the sample be changed because of sample down, thus the stabilization between the sample in the warranty test process.
