The specific embodiment
As Fig. 1 and Fig. 2 and shown in Figure 3, this plane abrasive belt glazing machine comprises a frame 1, is provided with driving wheel 1, driven pulley 1, driving wheel 24, driven pulley 25 and two abrasive bands 6 on frame 1.
Driving wheel 1 all is connected on the frame 1 with driven pulley 1, and they are all rotatable, and driving wheel 1 links with power set.Driving wheel 24 and driven pulley 25 also are connected on the frame 1, and they are also rotatable, and driving wheel 24 links with power set.In the present embodiment, power set are motor 7, driving pulley 8, driven pulley 9 and driving-belt 10, and driving pulley 8 is connected in the rotating shaft of motor 7, and driven pulley 9 is connected on above-mentioned driving wheel 1 or the driving wheel 24, driving-belt 10 is enclosed within on driving pulley 8 and the driven pulley 9, sees shown in Figure 4.
Wherein an abrasive band 6 is enclosed within on driving wheel 1 and the driven pulley 1, and an other abrasive band 6 is enclosed within on driving wheel 24 and the driven pulley 25.And these two abrasive bands 6 are adjacent.
6 outsides, abrasive band between driving wheel 1 and the driven pulley 1 are the polishing face 6a in this abrasive band, 6 outsides, abrasive band between driving wheel 24 and the driven pulley 25 are the polishing face 6a in this abrasive band 6, and the polishing face 6a in these two abrasive bands 6 be in over against the position.
6 inboard also is provided with top-pressure mechanism in the abrasive band, and top-pressure mechanism comprises guide 11, top-pressure part 12 and impeller 13.Guide 11 is connected on the frame 1, and top-pressure part 12 along continuous straight runs are located in the guide 11 and guide 11 is all stretched out at the two ends of top-pressure part 12.
Guide 11 in two top-pressure mechanisms be in over against the position, and both under the promotion of impeller 13 its moving direction also over against.
As shown in Figure 2, an end of impeller 13 is articulated on the frame 1, and an other end of impeller 13 is provided with and can makes the control device of impeller 13 around its hinged place swing.Control device comprises spring 14 and drag-line 15, and spring 14 is located at impeller 13 tops, and the two ends of spring 14 are connected in impeller 13 tops and frame 1 top respectively.Drag-line 15 is located at impeller 13 bottoms, and the two ends of drag-line 15 are connected in impeller 13 bottoms and frame 1 bottom respectively.The bottom of frame 1 is provided with the pedal that can step on 16, and an end of drag-line 15 just is connected on the pedal 16.
In the present embodiment, be equipped with the teeth 13a that arcuation distributes on two impellers 13, and the teeth 13a on these two impellers 13 is meshing with each other together.Make two impellers 13 to swing synchronously by such structure.
When workpiece is polished, workpiece is placed between the polishing face 6a in two abrasive bands 6.Then, the operator steps on pedal 16, makes impeller 13 around its hinged place swing, and impeller 13 swing backs promote top-pressure part 12 and move with respect to guide 11.Top-pressure part 12 after moving makes polishing face 6a to abrasive band 6 outside projectioies with regard to roof pressure in polishing face 6a inboard, just can be resisted against the two sides of workpiece after the polishing face 6a projection in two abrasive bands 6 respectively, thereby simultaneously two faces of workpiece is polished.
After operator's pin was removed from pedal 16, impeller 13 returned back to initial position under the elastic force effect of spring 14.Top-pressure part 12 oppositely shifts out, thereby makes the polishing face 6a in abrasive band 6 not to outer lug, is convenient to next time workpiece be placed between the polishing face 6a in two abrasive bands 6.
