Description
Technical field
The utility model relates to a kind of Imitation Rock Porcelain Tiles (stone material) grinding head for polishing, is specifically related to a kind of grinding head for polishing that improves abrading block wobble drive mode, belongs to construction material process equipment field.
Background technology
In existing Imitation Rock Porcelain Tiles (stone material) grinding head for polishing equipment, a kind of grinding head for polishing that adopts the swing type abrading block is arranged, its application is the most extensive, and its each abrading block drives corresponding fork by cam and realizes.
Shown in figure 10; Abrading block swing mechanism assembly is launched into plane can be found out; It drives the structure that abrading block is swung for putting cam on a kind of; Comprise cam 6, active both arms fork 7, driven both arms fork 8, abrading block mount pad 21 and abrading block 25; Active both arms fork 7 is installed on the bistriques rotation mount pads through rotating shaft 24 with driven both arms fork 8, and active both arms fork 7 is connected the abrading block mount pad respectively with driven both arms fork 8, and the abrading block mount pad is with initiatively both arms fork 7 or abrading block mount pad can rotate around rotating shaft 7 with active both arms fork 7 synchronously.Initiatively on two hold-down arms of both arms fork 7 roller 71 is installed and contacts with cam 6, adjustment screw 81 is installed on driven both arms fork 8 contacts with roller 71, driven both arms fork 8 driving forces are transmitted through the adjustment screw 81 and the contact position of roller 71.Its operation principle is as shown in Figure 4, and cam 6 drives initiatively both arms fork 7, and initiatively both arms fork 7 drives driven both arms fork 8, makes the abrading block that is connected on the fork do reciprocal swing.The grinding motion of bistrique is that abrading block rotatablely moves and the compound motion of abrading block around two kinds of motion compositions of left rotation and right rotation swing of rotating shaft around the circumference of main shaft, abrading block and institute's linear contact in flat surface grinding, so grinding pressure is big.Because abrading block swings, grind pure abrasive particle can in this swing, squeeze very soon sand that the broken processing corner angle that make new advances have processed simultaneously also can with grind the discharge easily in side-to-side movement together of pure abrasive particle, and be unlikely to stop up the slit of abrading block.
In the course of the work, adjustment screw 81 changes with the contact point gap length of roller 71, and the process of abrading block 22 swings can produce impact, causes vibration and the very big noise of generation.In order to keep normal work, above-mentioned gap is strict controlled within certain scope, otherwise can produce vibration; But in practice, there is bigger difficulty in this clearance control, makes bistrique produce very big vibration; Bistrique can't normally move, and has only minimum is adjusted in the gap just to be overcome the problems referred to above, but can quicken the wearing and tearing of adjustment screw 81 in operation like this; Need carry out the adjusting play often in the useful life, make troubles to production.
Simultaneously, when active both arms fork 7 was in horizontal level, two rollers 71 above it all contacted with the end face of cam 6; But when walking around this position, initiatively both arms fork 7 has only single roller 71 to contact with the end face of cam 6, and another one roller 71 is unsettled cam 6 end faces that leave; Process in the bistrique swing; Unsettled roller 71 can contact cam 6 end faces once more, impacts thereby produce, and causes vibration and noise.
