SU101076A1 - A machine for spreading glue and applying an abrasive powder to the periphery of a cotton polishing wheel - Google Patents

Description

In order to prepare the surface before the electrolysis decorative coating of metal, for example, automobile, bicycle and other parts, polishing is applied with base (cotton) circles mounted on the spindles of the polishing machines. These razors are made by sewing end-to-end threads of individual sliced fabric discs.

Ready iolirovaly circle has a layer of abrasive burrs on the periphery. In the process, wear of the abrasive layer and the main fabric of the circle. The worked steep restoration is carried out by smearing its periphery with glue and then rolling it with an abrasive powder, but these operations are performed manually.

The proposed machine is intended for the mechanization of this work. This is achieved by using a crank in it, performing a swinging motion to feed the processed circle at its end while moving in one direction to an endless chain with glue passing through the bath with glue and when moving in the other direction to the bath with abrasion

iU) pouiKOM. Janna mounted on a movable table.

In the drawing, a kinematic diagram is given of the south machine. Above the executive table / committing ;; o: n; military and economic. moving along arrows 2 and nesui, bath 5 with abrasive powder and bath 4 with glue, pomei, crank 5, receiving a rocking motion in a turntable, in a woven plane. . The crank J carries at the end the processing of POLY, an equal cr} r 6. The crank 5, having made swinging movements, delivers the polishing wheel IRN to the movement; up to the endless chain 7 with H1, currents. The drive shaft 8 is of infinite value of 7 volts. It is mounted in wall 4 with glue and while moving the chain, old brushes with nylon pads are made from the bottom of the tub.5 bath 4, smeared with glue and. Applying under the action of the spring 9 to the knotted moty. 5 to the polishing wheel 6, turn it and grease the edge of the wheel with glue. When the Lyutyl 5 moves downward, it delivers polishing | Lgcr} t 6 3 to the bath 3, where the feather of the circle rolls over with an abrasive. The table receives a reciprocating drive from the pneumatic actuator 0. The crank 5 and rotates swinging movements from the electric motor 11 through the belt drive 12 and the crank / 5. The endless chain 7 with brushes is driven by another engine through the worm gear and gear 14 and the drive shaft 8. The shaft 8 via the worm gear 15 reports rotation. The cam 16, which through the lever 17, acts on the switch 18, turns off the electric motor and thereby stops the movement of the endless chain 7. At the same time, the same lever 17 acts on the crane of the drive 10, which converts the table / to the rolling operation of the circle. The deactivation of the electric motor // is realized by means of the lever 19 when turning the cam 20 by the worm gear 21, rotated by the crank shaft 13. The lever 19 acts on the switch 22 of the electric motor // and on the valve of the pneumatic cylinder 23

to remove the finished polishing wheel 6 from the bath 3 with an abrasive powder. To adjust the size of the lowering of the motil 5 cl} the screw of the pair 24 is rotated by hand with a flywheel 25.

Subject invention

A machine for spreading glue and applying an abrasive powder to the periphery of a cotton polishing wheel, characterized in that, in order to mechanize the process, a crank is used to perform swinging movements to feed the workpiece placed at its end when moving in one direction to an endless chain with brushes passing through a bath with glue, and when moving in another direction - to a bath with abrasive powder installed on a movable table.
