When utilizing two parallel roll support cylinder shape instruments, cylindrical tool can only rotate in original place, and moving axially of difficulty or ease implementation tool, needs continuous travelling workpiece, cannot realize automatically all polishings.The cylinder that simple utilization drives cylindrical tool to move axially or mechanical arm, there are the following problems in meeting: 1, because cylindrical tool constantly rotates, cylinder or mechanical arm and its binding site need to adopt pulley structure, this complex structure, can form resistance, long-time use affects cylindrical tool at the uniform velocity verticity because resistance increase.2, vibrations and the natural travelling performance naturally of cylindrical tool can be affected after applying external force, cause polishing problem of non-uniform.
Utility model content
The purpose of this utility model is to provide the quick sanding apparatus in a kind of surface to the workpiece with arc surface, to reduce operation easier, reduces equipment complexity, provides working (machining) efficiency and machining accuracy.
Adopt following technical scheme for achieving the above object: a kind of work-piece polishing device with arc-shaped surface, comprise support and rack-mount two parallel rolls, distance between two carrying rollers is less than circular arc works width, to make cylindrical or arc-shaped work.Two carrying rollers and driving mechanism are in transmission connection and rotating Vortex.Also be provided with workpiece polishing mechanism.Below between two carrying rollers is provided with discoid axle and drives roller, axle is driven roller and is in transmission connection by transmission mechanism and driving mechanism, the annulus driving roller at axle evenly there is axial trough respectively, in each bearing, be separately installed with rubber wheel, in each axial trough in same annular, be provided with the rotating shaft of annular shaft as each rubber wheel.Thus, can move vertically under the integral-rotation effect that cylindrical work drives roller at axle.Cylindrical work is driven by two carrying rollers simultaneously, constantly rotates.Now, be provided with multiple rubber wheel because axle drives on roller, rubber wheel can not only make it move axially by support cylinder shape workpiece, also can rotate with cylindrical work.Thus axle can be avoided to drive roller surface affects the workpiece speed of rotation with cylindrical surface because there is sliding friction, cause polishing problem of non-uniform.
Described elasticity workpiece polishing mechanism comprises the grinding head of a cylinder or truncated cone-shaped, is fixed with bull stick in grinding head back center; Pivoted housing is set with, spline joint between bull stick and pivoted housing outside bull stick; Described pivoted housing is arranged in rack shaft holder by bearing, and described pivoted housing is connected with motor by transmission mechanism; Spring is connected with between grinding head and pivoted housing.Described transmission mechanism installs driven wheel of differential on pivoted housing, and machine shaft installs drive bevel gear, and drive bevel gear is meshed with driven wheel of differential.Or described transmission mechanism installs driven pulley on pivoted housing, and machine shaft installs drive pulley, and drive pulley is connected by belt transmission with driven pulley.
Beneficial effect: 1, the utility model utilizes two parallel carrying rollers to support cylindrical work, thus need not consider cylindrical work fixation problem, also need not consider to determine axle center problem.
2, utilizing axle to drive roller makes cylindrical work automatically push ahead, and axle can be avoided to drive roller surface affects the workpiece speed of rotation with cylindrical surface because there is sliding friction, cause polishing problem of non-uniform.Thus guarantee grinding head can along the lateral surface of cylindrical work spin shape polishing, there is grinding homogeneity, effective advantage.
3, elasticity workpiece polishing mechanism provides appropriate pressure and screen resilience, guarantees that polishing pressure stability is accurate.The axle rubber wheel driven on roller is conducive to promoting cylindrical work and moves forward and non-slip.
4, the utility model structure is simple, and easy processing and manufacturing, uses easy to operate, can improve machining accuracy and working (machining) efficiency, very be beneficial to promotion and implementation.
