(54) DEVICE FOR TAPE GRINDING

 . /;

The invention relates to the woodworking industry.

A device is known for the accurate shafting of flat pieces of wood, consisting of screed and belt grinding. ball head with pinch roller.

However, the known device is not secured; it requires the required quality of the surface of the products.

; The aim of the invention is to improve: the quality of the surface of the 1-st. To this end, the grinding head is equipped with a jMOM mechanism for reciprocating | -Ivary movement I around the axis perpendicular to the plane of | Ttola, and kinematically connected with it by a screw for adjusting the grinding heads to a certain angle of rotation, having right and left hand wheels mounted on them with adjustable sleeves .

FIG. 1 depicts the proposed

device, side view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 - device in plan.

On the bed 1 fixed table 2, for example, in the form of a conveyor, and brackets

3. In the brackets 3, one end of the axle 4 is hingedly mounted, on the other ends of which grinding heads 5 with irons 6 are rigidly suspended.

On the bed 1, the mechanism for cutting the grinding heads 5 is fixed at a certain angle of rotation consisting of a screw 7 with the right and left cutting and movable stops 8; chained transmission of Mi 9 and Yu with a drive of rotation of grinding heads 5, for example, a hydraulic one containing a hydraulic panel 11 with a high-speed one (spool 12 and a reverse il3 slide valve in Four g of a dropper 14, and arranging the JCTBOM 15 to regulate the course of hydrodilia | firewood 14.

f The device works as follows.

Claims (1)

I- When submitting the workpiece to | table 2, the rotation of the shafts | fovalny heads 5 is adjusted depending on the width of the workpiece to adjust the frequency of their reciprocating rotational motion. To do this, by turning the screw 7, I set the distance between the movable MB stops tl, the wider width, and my part. this, through the valuable gear 9, is automatically set by the center of the high-speed spool 12, the frequency of the rotational movements of the knob-f 5 heads; At the same time, through the chain drive 10, the mechanism 15 for adjusting the stroke-movement of the indra 14 is adjusted, which {I 1e in my echer / No. adjusts the angle of rotation of the grinding heads 5. After setting w; w | foam heads include feeding of the workpiece and rotational drive of grinding heads 5, while grinding heads perform reverse rotation around the 4 axes along the width of the workpiece, forming radial strokes in one direction in one direction, and opposite radial strokes in the other direction, thereby obtaining a clean surface. The other grinding the hulk with the smaller grating of the sanding belt, making the same movements, produces the final processing. The invention of a belt grinding device made in the form of a table and a grinding head with a pressing iron, characterized in that, in order to improve the quality of the surface being treated, the grinding head is provided with a back and forth movement mechanism about an axis perpendicular to the plane of the table and kinematically the screw of adjustment of grinding heads connected with it at a certain angle of rotation, having sections of the right and left cutting with movable stops mounted on them.
