Abstract

The invention relates to metal working and can be used for finishing flat surfaces. The purpose of the invention is to simplify the design by using a mechanical drive instead of a hydraulic one. The machine contains a frame on which the guides are mounted. A table 8 is mounted on the frame by means of the carriage 3. On the carriage 3 there is a slot 9 in which the rail 7 is mounted for reciprocating and contacting with adjustable stops, which serves for lateral movement of the table. The rail 7 interacts through gears 6 with rollers 4 mounted on carriage 3 and equipped with eccentric fingers 12. Eccentric fingers 12 are placed in apertures "a" of table 8. For one reciprocating longitudinal course, the table performs a math movement in the transverse direction, providing the treatment of the entire polished surface with a grinding tool made with a pad of flap wheels 21. 3 Il.

The invention relates to metal working and can be used for finishing flat surfaces.

The purpose of the invention is to simplify the design of the machine through the use of a mechanical drive for moving a table instead of a hydraulic one.

The device comprises a frame 1 on which horizontal guides 2 are mounted, which serve to move the carriage 3. The carriage is equipped with two rollers 4 mounted in thrust support pins 5 and having gears 6 mounted on them that engage with the rail 7, which serves transverse movement of the table 8, freely mounted (for example, by means of a clip) on the carriage 3. In the table 8 there are two holes a. The rail 7 is placed with the possibility of reciprocating movement in the slot 9, made on the carriage 3 parallel to its axis, and is in contact with the adjustable stops 10 and 11; mounted on the bed 1. The rollers 4 are provided with eccentric fingers 12 located in the holes a of the table 8.

On the table 8 is placed a magnetic plate 13 serving to secure the workpieces being processed. On the carriage 3, the rail 14 is rigidly mounted, interacting with the bristles 15 of the 16 feed box and in contact with the microswitches 17 and 18, indicating the command to reverse the table 8.

On the base 1 there is a grinding wheel 19, in which a grinding tool is fixed, which incorporates a mandrel 20 with a set. lenecTKOBbJx circles 21.

The device works as follows.

The parts to be machined are mounted on a magnetic plate 13. An electric motor (not shown) is turned on, which drives a 1-ton rotation of the jaws 15 of the box 16 ydach. The gear 15, interacting with the rail 14, communicates the longitudinal movement of the carriage 3 with the table 8 placed on it. Simultaneously, the rotation DT of the electric motor is communicated to the grinding tool, and the grinding tool is fed into the work area.

the rail 7 rests on the anvil 10, and the carriage 3 continues to move forward. The gears 6, the arrival of interaction with the stationary rail 7, rotate, jointly rotating the rollers 4 with eccentric fingers 12 arranged on them located in the holes of the table 8. Table 8, freely mounted on the carriage 3, is shifted by a specified amount in the transverse direction.

At the end of the stroke, the rail 7 again abuts against the stop 11, the table by means of gear 6, the rollers 4 and the ex20 of the centric fingers 12 performs a lateral movement, returning to its original position. The rail 14 rests on the microswitch 18, together with a reverse command. The cycle is repeated.

The invention makes it possible to increase the productivity of a machine by providing processing of the entire ground surface in one reciprocating longitudinal course. and simplify its design, since the longitudinal and transverse feeds of the table are carried out without using), 1 high-speed transmission using simple mechanical means.
