Description
Technical field
What the present invention relates to is a kind of experimental provision, specifically, is a kind of device that is used for abrasive band frictional wear experiment, belongs to mechanical engineering technical field.
Background technology
Along with the development of machinery manufacturing industry, belt sanding has become one of effective ways of precision, ultraprecise processing.Abrasive belt grinding machine has obtained application more and more widely.But in the abrasive belt grinding machine grinding process, in the time of the grinding work piece of front, abrasive band, the back side, abrasive band closely contacts with contact wheel.Though the back side, abrasive band does not have abrasive particle, the contact wheel wearing and tearing are still comparatively serious, influence working (machining) efficiency and precision.And it is higher to change the contact wheel cost, and this becomes a big bottleneck of this type of abrasive belt grinding machine development of restriction.And that the main cause that causes the contact wheel wearing and tearing of this type of abrasive belt grinding machine is the linear differential of abrasive band and contact wheel is very big, thereby produces strong friction.So need study the friction and wear behavior of contact wheel by abrasive band frictional wear experiment, the improvement of abrasive belt grinding machine provides foundation for future.
Friction-wear test mainly is divided three classes at present: sample experiment, platform experiment and use experiment.Wherein the sample experiment is exactly under given condition, and the friction member of required research is made the less sample of size, experimentizes on corresponding experimental machine, is mainly used in the dissimilar process of friction and wear of research under the laboratory condition.Platform experiment is exactly on the basis of sample experiment, optimizes the material that can satisfy the friction and wear behavior requirement substantially, makes the friction member similar to the practical structures size, and the simulation actual service conditions experimentizes.
Owing to there is not special-purpose experimental machine, the platform experiment mode is adopted in friction wear experiment in abrasive band usually.Bench test device adopts two-wheel bi-motor mechanism usually: driving wheel and contact wheel are respectively by motor-driven, the abrasive band is by the guide wheel mechanism tensioning, and guide wheel, driving wheel and contact wheel and the back side, abrasive band walked around in the guide wheel mechanism all closely contact with contact wheel with above-mentioned guide wheel, driving wheel.Wherein, but the tensioning degree in abrasive band is regulated in the guide wheel mechanism translation, and the drive motor of driving wheel and contact wheel can be selected respectively as required.Generally, the driver motor rotating speed is higher, and the contact wheel motor speed is less.Abrasive band and contact wheel all can be changed as required.The problem that this experimental provision exists is: when the contact wheel size is big, can all make troubles to its preparation and test.In addition, this experimental provision can only be simultaneously carries out the friction wear experiment to a kind of contact wheel of material, and efficient is not high.
Through new, do not find identical with theme of the present invention or similar bibliographical information as yet to looking into of prior art.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of device that is used for abrasive band frictional wear experiment is provided, make it replace original experimental provision, allow platform experiment in conjunction with the small and exquisite advantage of sample experiment test specimen, make the preparation and the test of experiment test specimen more convenient, improve abrasive band frictional wear experiment efficient simultaneously.
The present invention is achieved by the following technical solutions, the present invention includes: driver motor, contact wheel motor, driving wheel, contact wheel, guide wheel mechanism, wedge, abrasive band, support and base.Driving wheel is connected with the contact wheel motor with driver motor respectively with contact wheel, and the abrasive band is by the guide wheel mechanism tensioning, and guide wheel, the driving wheel walked around in the guide wheel mechanism all closely contact with contact wheel with above-mentioned guide wheel, driving wheel with the contact wheel and the back side, abrasive band.Wedge is installed in the external peripheral surface of contact wheel.Guide wheel mechanism is rack-mount, and driver motor, contact wheel motor, support are installed on the base.
Among the present invention, be evenly distributed with a plurality of wedge-shaped slots on the whole external peripheral surface of contact wheel, embed a wedge that is complementary with it in each groove respectively, wedge material therefor and its tightness can be determined according to needs.After installing, wedge can carry out turning again to guarantee that it is smooth bright and clean to the contact wheel external peripheral surface.
Guide wheel mechanism among the present invention can be the slide block slide block mechanism, is made up of guide wheel, slide block, balladeur train, linkage assembly.Balladeur train is fixed on the support, linkage assembly be installed on the balladeur train after slide block is connected.The upper and lower strut end of linkage assembly respectively is equipped with a guide wheel.
When adopting the slide block slide block mechanism as guide wheel mechanism, the present invention regulates the tensioning degree in abrasive band along the translation of balladeur train by slide block.After tensioning was finished, guide wheel, driving wheel, contact wheel and the back side, abrasive band that the abrasive band is walked around in the guide wheel mechanism all closely contacted with above-mentioned guide wheel, driving wheel, contact wheel.Behind driver motor and the contact wheel electric motor starting, drive driving wheel respectively and contact wheel rotates in opposite direction.Because driving wheel rotating speed height drives the abrasive band and realizes the friction of the back side, abrasive band to the contact wheel surface along rotating with the driving wheel equidirectional.This experimental provision can be simultaneously carries out frictional wear experiment to the wedge of a plurality of different materials.After experiment finished, the wedge of different materials carried out test analysis on the detachable lower contact wheel, and abrasive band and contact wheel also can be changed as required, make whole experiment very efficient convenient.
The present invention replaces original contact wheel with the contact wheel and the wedge that improve back band wedge-shaped slot, has realized the convenience of test material preparation and test and the high efficiency of whole experiment.
The present invention compared with prior art has substantive distinguishing features and marked improvement.The present invention can suitably be out of shape according to concrete process conditions and deviser's requirement, and is simple in structure, easy to manufacture.Because the present invention can be simultaneously the wedge of a plurality of different materials is experimentized, thereby be very easy to the preparation and the test of test specimen, improved the efficient of this belt sanding wear test.
