Abstract
A sander suitable for an outer periphery of a timber variable cross section mainly comprises an abrasive belt, a feeding plate, a material-holding hopper, a pinch roller mechanism, a rod end oscillating bearing, a screw and a spring. During a working process, a pinch roller pinches a work piece on the feeding plate against the abrasive belt, the clockwise rotation of the pinch roller and the abrasive belt drives the work piece to rotate anticlockwise and the work piece is polished along the circumference of the work piece by the abrasive belt, and at the same time the work piece contacts gradually with the pinch roller along the axis direction of the work piece and moves along the feeding plate, and is finally ejected to the material-holding hopper. When the cross section of the work piece changes, on one hand, the pinch roller, a pinch roller cross support, the rod end oscillating bearing and the screw move horizontally relative to a machine frame, on the other hand, the rod end oscillating bearing enables the pinch roller and the pinch roller cross support to be capable of deflecting slightly relative to the screw, and at the same time a pinch roller slant support deflects slightly around a pinch roller slant support drive shaft to enable the relative position between the pinch roller and the work piece to change automatically, and therefore the polishing of the outer cylinder surface is realized. The outer periphery of the timber variable cross section has the advantages of being good in polishing quality, strong in adaptability, simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of sander, especially relates to a kind ofly for the sander to the variable cross-section outer cylinder surface polishing of timber, belongs to the woodworking machinery field.
Background technology
Woodworking machinery mainly be from log saw cut open, saw used the woodwork process digs to being processed in treating of wood, splicing, boring, polishing, with the process equipment such as post-processed.Woodworking machinery can be divided into the subsidiary engine of carpenter's sawing class, thicknessing and planning machine, wood-turning machine, wood-milling machine, wood boring machine, wood sanding machine, woodenware external coating equipment, finishing, sharpening wood cutter etc.
Wood sanding machine is that abrasive band for no reason is stretched on two or more belt wheels, and the rotation by belt wheel makes the abrasive band produce cutting movement, realizes the sand of timber is cut polishing.Abrasive band polishing is a kind of elasticity grinding, and the title of " cold conditions grinding " is arranged, the little and good stability of system's vibrations, and polishing velocity is stable, thereby the polishing workpiece surface quality is high, is used widely.Existing sander generally is used for the polishing of plane, uiform section outer cylinder surface, and the polishing of variable cross-section outer cylinder surface is used manual grinding or used the finishing method of gauge finder to realize.By hand carry out polishing, inefficiency, cost is higher, and polishes inhomogeneously, is difficult to the quality requirement that reaches unified; Use gauge finder to carry out polishing, the processing equipment complex structure, when the surface of the work change of shape, gauge finder just needs to change, change, and flexibility, the adaptability of production are relatively poor.So, in the urgent need to a kind of can automatic polishing and be suitable for the sander of the variable cross-section outer cylinder surface of timber.
The utility model content
The purpose of this utility model is for variable cross-section outer cylinder surface polishing difficulty, the poor problem of product flexibility, and a kind of abrasive band polishing machinery that is applicable to the variable cross-section outer cylinder surface of timber is provided.For the outside cylinder workpiece of vertically sectional dimension variation, can automatically realize the polishing of outer surface of workpiece, and polished amount is even, adjustable.Utilize abrasive band polishing little to the damage of timber itself, improved the quality of product.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of variable cross-section outer cylinder surface polishing machine that is applicable to timber mainly is comprised of frame, abrasive band driving wheel, abrasive band driven pulley, abrasive band regulating wheel, abrasive band, feed mechanism, pressing wheel mechanism, spherical plain bearing rod end, bearing pin, free bearing, screw rod, handwheel and power section.During work, manually material loading is placed on workpiece on the delivery sheet.Motor arrives the abrasive band driving wheel to transmission of power by the V tape handler, and the abrasive band is turned round along clockwise direction; Another motor on the pinch roller of transmission of power in the pressing wheel mechanism, turns round pinch roller by V band, synchronous belt drive mechanism along clockwise direction; Workpiece is pressed against on the abrasive band under the effect of pinch roller, turned round in the counterclockwise direction by the rotating belt in pinch roller and the abrasive band part of starting building, by abrasive band polishing, while workpiece under the crowded stranding effect of pinch roller moves at last along delivery sheet and injects on the receiving hopper workpiece along circumference in turning course.The polished amount of workpiece determines by the sand grains label in the compression degree in workpiece and abrasive band and abrasive band, and the compression in workpiece and abrasive band by adjusting handle screw rod is moved and then driven rod end oscillating bearing, pinch roller move realization.For variable cross-section outer cylinder surface workpiece, when diameter of work changes, pinch roller, pinch roller lateral frame, spherical plain bearing rod end, free bearing, the relative frame of screw rod move horizontally on the one hand, spherical plain bearing rod end makes pinch roller, the relatively screw rod trace deflection of pinch roller lateral frame in the pressing wheel mechanism on the other hand, and the pinch roller tilted supporter is around the deflection of pinch roller tilted supporter power transmission shaft trace simultaneously.Like this, the relative position of pinch roller and workpiece changes with the workpiece changes of section automatically in polishing process, guarantees that workpiece is in the realization polishing of the basis of original shape.
The beneficial effects of the utility model: utilize the characteristic of the flexibility in abrasive band, two rod members that spherical plain bearing rod end can be connected with micro-deflection and the elasticity of spring, automatically realize that pinch roller moves with the diameter of work variation, thereby finish the polishing process of variable cross-section outer cylinder surface.During the workpiece size specifications vary, the bolt link position that only needs to adjust pinch roller tilted supporter and pinch roller lateral frame gets final product.Quality of finish is good, and polishing efficiency is high, and mechanism structure is simple, and is easy and simple to handle, is easy to promote.
