SU1646802A1 - Machine for polishing flat surfaces - Google Patents

Abstract

The invention relates to metal working. The purpose of the invention is to simplify the design and increase the operational reliability of the machine. The machine comprises a frame provided with horizontal guides 2, on which a carriage with a table movably mounted on it is placed. The carriage and the table are connected to each other pivotally by means of two strips, the image of a hinged parallelogram with them. A magnetic plate 7 is placed on the table. On the opposite sides of the table there are wedges 9 and 10, which are designed to interact with the rollers 13 and 14. The rollers are mounted on crusty 11 and 12 mounted on the frame and providing transverse movement of the table. A cylinder is placed between the guides 2 of the bed, telling the carriage to reciprocate along the guides 2. Under pressure of compressed air, the carriage with a table mounted on it and a magnetic plate 7 makes longitudinal movement. At the end of the translational longitudinal movement of the carriage, click 9, mounted on the table, comes into interaction with the roller 13, while the carriage continues to make translational motion, and the table with the magnetic plate 7 begins to make lateral movement by means of a hinged parallelogram. Then the carriage rests simultaneously on the stop 15, limiting its longitudinal course within the prescribed limits, and the microswitch 17, giving the command to the longitudinal reverse. The carriage begins to move in the opposite direction before the wedge 10 interacts with the roller 14, as a result of which the table returns to its original position. The carriage rests simultaneously on the anvil 16 and the microswitch 18, together with a reverse command. The cycle is repeated. 4 or
