Description
Affiliated technical field
A kind of high-speed friction wear test servicing unit that uses on the lathe that is configured in belongs to frictional wear test device.
Background technology
At present, generally on existing friction wear testing machine, carry out friction-wear test and have shortcomings such as frictional vibration is big, material style manufacturing cycle is long, and test condition is subjected to the influence of device structure, the attainable scope of friction velocity is less, can not satisfy the demand that wearing and tearing are studied to high-speed friction.As the omnipotent friction wear testing machine of MMW-1A, maximum speed is 2000r/min, but the sample contact diameter is 46mm to the maximum, and attainable maximum slip velocity is 290m/mim, and frictional vibration is quite obvious after removing rotating speed to be higher than 1000r/min, has a strong impact on the reliability of test.Be put to the test the in addition restriction of environment, but the operating space of testing machine is smaller, and some advanced jet cooling and lubricating technology can not be applied in the friction-wear test easily goes.
Document " the high-speed friction Research on Wear Characteristics of ultrafine gain size " (Pan Yongzhi etc. the high-speed friction Research on Wear Characteristics of ultrafine gain size. tribology journal .2008 January) a kind of method of carrying out friction-wear test on lathe proposed, utilize lathe that power is provided, use three-dimensional dynamometer to measure the size of each power.The advantage of the method has, and specimen size can strengthen as required voluntarily, increases the slip radius and can realize high-speed friction, and linear velocity can reach 900m/min; The lathe rigidity is better than testing machine, vibrates for a short time, and test effect is good; Experimental enviroment adaptability is strong, can easily jet cooling and lubricating technology be applied in the test to go.But how undeclared how imposed load keeps constant normal force in the article, and accurately apply, transmitted load is for guaranteeing the sliding friction behavior, repeat experimental study and play key effect.
Summary of the invention
The utility model proposes a kind of being installed on the lathe at the problem that existing friction wear testing machine exists, and cooperates the simple in structure, with low cost of dynamometer use, the high-speed friction wear test servicing unit of transmitted load that can be more accurate.
A kind of high-speed friction wear test servicing unit that uses on the lathe that is configured in, it is characterized in that: comprise base plate, base plate is simultaneously installed the horizontal guide rail pair, auxiliary body is connected with the slide block regulation of horizontal guide rail pair, auxiliary body one end is equipped with the chuck that is used for clamping sample I, the other end links to each other with a horizontal spring one end, and the horizontal spring other end links to each other with loading bolt, and loading bolt is by the bolt block support that is installed on the base plate.
Described chuck head has pilot hole, cooperates with bolt, nut to be used for the sample that clamping has the clamping hole.Afterbody has locating slot and screw fit is used for chuck is fixed in auxiliary body, can adjust the chuck height by locating slot.Spring contacts with auxiliary body on the slide unit that is installed in guideway, comes transmitted load by auxiliary body.
The beneficial effects of the utility model are, this servicing unit is simple in structure, and is with low cost, easy for installation, can transmit normal load accurately, sample are required simple, and adaptability is good.Test can be by the high engine speed range of lathe, and the design of the major diameter of disk body sample II realizes high-speed friction, can reach 200mm as the slip diameter of disk body sample, and when rotating speed was 1500r/min, friction velocity just had 942m/min.The lathe vibrations are little, pilot system precision height, reliable results, and experimental enviroment adaptability is good, can satisfy the application of jet cooling and lubricating technology in friction-wear test.

Embodiment
The utility model is realized by following measure: device comprises base plate 1, rail plate pair 2, chuck 3, load maintainer.Load maintainer comprises auxiliary body 4, spring 5, bolt block 6, loading bolt 7.Each purposes and characteristics are:
Chuck 3 is installed on the auxiliary body 4, is used for clamping sample I 12; The chuck shape can be according to the shape otherwise designed of the required sample I 12 of test.Chuck 3 has locating slot 9, can adjust up and down with auxiliary body 4 link positions, and is top to height of center with lathe.
Load maintainer is installed on the base plate 1, to auxiliary body 4 imposed loads.
As shown in Figure 4, whole device 13 is installed on the dynamometer 14 by base plate 1, dynamometer 1 is installed on the carriage box of lathe imitation turning process.Sample I12 is installed on the device chuck 3, and sample II 11 makes the disk body shape and is clipped on the scroll chuck 10.Start lathe, disk body sample high speed rotating, the control carriage box moves and makes two samples 11 can carry out friction-wear test with 12 mutual stressed contacts.The decrement that the size of normal load can the spinning in and out by bolt changes spring is regulated and is kept.The big I of normal load and friction force is measured by dynamometer simultaneously, can draw friction factor by calculating then.By improving the friction radius of lathe rotating speed or increase disk body sample II 11, can obtain higher friction speed, realize high-speed friction.The machined into good environmental adaptability can conveniently be applied to jet cooling and lubricating technology in the test.
