Description

A kind of lumber sanding grinder
Technical field
The present invention relates to a kind of sanding machinery, a kind of lumber sanding grinder especially is provided.
Background technology
Lumber sanding grinder tool frosted parts of the prior art mostly are rotary grinding wheel, and it contacts grinding with treating sanding woodenware spare by line.This grinding structure grinding part becomes line to contact with workpiece, and in the grinding of finish grinding, the grinding efficiency of above-mentioned grinding pattern is very low.In addition, because grinding emery cloth wheel speed is very high, use 600-800 purpose crosus cloth fine ginding, the wood chip that emery cloth is ground is soon stuck with paste, and water wave can appear in the surface of the work injustice with such milling drum grinds,
Also have a kind of emery cloth plate that is fixed on the camshaft in the prior art, under eccentric drive, do flat circle motion grinding work piece plane.On the sander of this structure, the emery cloth plate is fixed on the frame by spring, and simultaneously, this emery cloth plate of eccentric wheel effect makes the emery cloth plate swing on horizontal plane.Because spring has the longitudinal extension performance, thus, makes the emery cloth plate not only swing on horizontal plane, but also longitudinal extension.Owing to require eccentric rotating speed very high in the sanding operation, be very easy to damage so connect spring, in order to guarantee its service life, maintenance such as usually be lubricated, cumbersome; In addition, use emery cloth plate correct grinding woodenware surface, need the emery cloth board plane to contact, like this with the workpiece held stationary, grinding performance is better, but existing sanding machine uses spring one class connector, can not guarantee that the emery cloth plate contacts with the steady of workpiece, therefore, the grinding work piece difficult quality improves.
Summary of the invention
The objective of the invention is to improve the defective of prior art, it is steadily reliable to provide a kind of correct grinding grinding attachment wherein to contact with workpiece, thereby make grinding quality be improved, the while grinding attachment is without maintaining, and the lumber sanding grinder of long service life.
The object of the present invention is achieved like this:
Lumber sanding grinder provided by the invention comprises a frame, one fine grinding device is set on this frame, comprising an eccentric shaft device and an emery cloth plate, this eccentric shaft device comprises a main shaft, which is provided with driving member makes it to rotate with respect to this frame in order to be connected with power source, connect an eccentric shaft part in the lower end of this main shaft, the center line of this shaft part is parallel with the axis of main shaft, one side of described emery cloth plate sets firmly emery cloth, on its another side, set firmly an end of some isometric flexible columns, the other end of each flexible column is fixed on and makes this emery cloth plate be positioned at the below of described eccentric shaft part on the frame, described emery cloth plate is provided with a bearing liner case assembly that aligns with described main-shaft axis, and the lower end of the eccentric shaft part of described main shaft lower end connects firmly with the emery cloth plate rotationally by described bearing liner box; Described flexible column is the steel wire rope that steel wire strand twists into, and the following correspondence of described emery cloth plate is provided with workbench.
Being connected and fixed structure and can being of described steel wire rope and described frame and emery cloth plate: the two ends of steel wire rope respectively are connected a fixed disk, affixed described frame of this fixed disk and emery cloth plate.
On the frame of described emery cloth plate below workbench is set.
Lumber sanding grinder provided by the invention also comprises a workpiece transfer device, and described annular work piece conveyer belt is connected with tape handler, and the epipelagic zone of workpiece transfer device places on the upper surface of described workbench.
Between frame below the described emery cloth plate and workbench, be provided with elevating mechanism, make that the spacing between described workbench and the described emery cloth plate is adjustable, adapt to the specification of grinding work piece in using and take out the needs of putting into workpiece.
Described elevating mechanism can have multiple structure, the invention provides a kind of simple in structure but use reliably elevating mechanism easily: on described frame, set firmly some sprocket wheels rotationally, the center of this sprocket wheel has screw, set firmly screw rod on the described workbench bottom surface with the screw coupling, described screw rod is screwed onto in the described screw, a sheathed chain on some sprocket wheels, this chain combines with a drive sprocket, this drive sprocket is rotatably mounted on the frame, and the wheel shaft that is connected on it is connected with power source.When wanting self-powered platform, promptly start power source and make the synchronous original place of each sprocket wheel rotate, promptly make thus, just to make workbench rise or decline by each described screw rod synchronization lifting.
Transmission mechanism on the described workpiece transfer device can be supported on the elevator platform that is connected with the workbench one, thus can be so that workpiece transfer device and workbench synchronization lifting.
Lumber sanding grinder provided by the invention can also comprise the corase grind device, it comprises a gauze cylinder, it is connected with motor by belt mechanism and is rotatably mounted on the square beam, and this square beam is connected on a lifting hydraulic cylinder or the cylinder, and the plunger rod and the frame of this cylinder connect firmly.
Lumber sanding grinder provided by the invention, changing existing line contact sanding is face contact sanding, become unidirectional grinding and cut into circumference sand, connect the flexible column of being made by steel wire rope between emery cloth plate and frame, it compared with prior art, under the eccentric shaft effect in the vibration grinding process, steel wire rope can not produce longitudinal extension, and this can make emery cloth plate and workpiece keep good balance to contact, and grinding performance is good, the grinding quality height of workpiece, the fineness grade of processing work obviously improves.The high efficiency of this sander is compared with existing similar sanding machinery, can raise the efficiency more than 40%.Have, this sander is owing to contact well with workpiece again, and its energy consumption also reduces greatly, and energy-saving effect is obvious.The used motor of common sander needs 56KW, and the power of the motor of this sander can be 7.18KW.In addition, steel wire rope system flexible column does not in use need lubricated maintenance, but its service life is very long, can be tens times of spring flexible column life-span.
