Detailed description of the invention
Accompanying drawings detailed description of the invention of the present utility model.
As depicted in figs. 1 and 2, furniture panel cambered surface sanding device, comprises workpiece polishing mechanism, globoidal plate mechanism and panel clamping device;
Described workpiece polishing mechanism, comprises abrasive band 9 and a pair abrasive belt wheel 8, and abrasive band 9 is enclosed within a pair abrasive belt wheel 8, and the axle of abrasive belt wheel 8 is supported by support 18;
Described globoidal plate mechanism comprises globoidal plate 5, and globoidal plate 5 is arranged on the upper surface of one end of connecting rod 4; Connecting rod 4 other end is hinged on the edge of disk 1, and described disk 1 is arranged in frame 3, and can rotate around its center of circle; Described disk 1 also has alignment pin 2, corresponding frame 3 has locating slot 7, alignment pin 2 is inserted into locking in locating slot 7 and can realizes disk 1 and locate; Described connecting rod 4 is hinged fork 6 also, and described fork 6 is hinged in frame 3; Disk 1, connecting rod 4, fork 6 and frame 3 form parallelogram double-crank mechanism, rotating circular disk 1, and connecting rod 4 keeps level to move obliquely upward, globoidal plate 5 is reached between a pair abrasive belt wheel 8, along with connecting rod 4 highly raises, by abrasive band 9 median rise, form a protruding cambered surface;
Panel 12 clamps and is placed on median rise position, abrasive band 9 and polishes by described panel clamping device.
The lower surface that globoidal plate 5 one end installed by described connecting rod 4 also has chute 14, and described chute 14 forms sliding pair with slide block 15; Described slide block 15 is arranged on and supports cylinder 13 top, supports cylinder 13 and is arranged in frame 3, when connecting rod 4 motion puts in place time, withstands connecting rod 4 lower surface play support and position locking effect by support cylinder 13.
The cambered surface of polishing as required, chooses corresponding globoidal plate 5 and is arranged on connecting rod 4, rotating circular disk 1, drive link 4 moves obliquely upward, by below globoidal plate 5 abrasive band 9 and gradually jack-up abrasive band 9, until the cambered surface of abrasive band median rise reaches requirement, disk 1 is located by locking positioning pin 2; Locking support cylinder 13 simultaneously, realizes the position locking of connecting rod 4.
Described panel clamping device comprises panel holder 20 and bar cover 11, panel holder 20 is connected on bar cover 11, bar cover 11 is enclosed within pillar 10 and also can rotates around pillar 10, also comprise cylinder platform 16, cylinder platform 16 by bearing mounting column 10, and below bar cover 11, and cylinder platform 16 is at least provided with two lift cylinders 17, the bottom of the top connecting bar cover 11 of lift cylinder 17, lift cylinder 17 overlaps the lifting of 11 for control panel fixture 20 and bar, and lift cylinder 17 and cylinder platform 16 rotate around pillar 10 along with bar overlaps 11.
Panel holder 20 rotates and leaves above abrasive band 9, and rise panel holder 20 and bar cover 11 with lift cylinder 17, being encased in by panel 12 on panel holder 20 and clamping, rotated to by panel 12 above abrasive band 9, panel 12 is progressively fallen and polished by lift cylinder 17.After polishing terminates, then rise panel 12, rotate and leave abrasive band, take off the panel 12 of having polished.
Described support 18 there is mounting hole 19, for regulating the spacing of a pair abrasive belt wheel 8, when cambered surface change is swelled in abrasive band 9 time, to adjust the tensile force in abrasive band 9.
