(54) DEVICE TO THE MILLING MACHINE

I

The invention relates to a machine tool industry and can be used for machining grooves.

Known devices for machining grooves include a spindle with a free-e 11, tool. for deburring and a fixture mounted on the table with part 1.

The purpose of the invention is an increase in labor productivity due to the fact that the deburring is performed during the reverser of the cutter.

This goal is achieved by the fact that the device is equipped with a kinematically connected spindle, mounted with a psshorot shaft carrying a tool for removing burrs, and a copier mounted on the table, consisting of placed parallel and upper and lower bars and a flag hinged on the upper bar The shaft is provided with a bearing for interacting with the cam and flag.

FIG. 1 shows the proposed device, the cut; in fig. 2 shows section A-A in FIG. one; on fng. 3 shows a section BB in FIG. 2

On the base 1 of the device, which stands on the table 2 of the horizontal milling machine, there are installed 3 for fastening the part 4 and the copier 5, consisting of two horizontal bars connected between: (at the top, 6 and lower 7. Parallel to the spindle 8 a machine with a milling cutter 9 for milling a groove mounted on two earrings a shaft 10 with a 1 m planted on it with a tool (a milling cutter) 11 for removing zaesh (s and the console located

0 bearing 12. The shaft 10, together with the milling cutter 11, receives rotation from the spindle 8 by means of gears 13. The shaft 10 is suspended from the trunk 14 of the machine by means of a spring 15 and is in contact with the gear 5 through a subgrip 12. On the upper slat 6 of copier 5 The flag 16 is equally hinged with the same width as the arm 12, and the bar is grooved 17 to allow the bar 16 to contact the lower bar with the lower bar 7.% of the lower bar of the copier also have two slots 18 and 19 on both cTopoHbJE from the bar 16 for exit pod 12

The device works as follows.

When the table is fed forward, the groove is milled into the part by the cutter 9. At this time, the scraper 12, moving the lower plane 20 of the upper rail 6 of the copier 5, lifts the flag 16.

When the groove has been milled, the bearing is in the extreme left position, with the flag returning to its original position, i.e. falls under its own weight and the upper plane of the lower plan ki 7 of the copier 5. When the table moves backward, the bearing slides first along the plane 21 of the flag 16, the passage groove 18 in the lower bar, then along the lower plane 22 of the lower bar 7 of the copier 5. At this moment This is a burr in the part by the cutter 11. At the end of the table's reverse travel, the bearing 12 drops over the groove 19 and comes into contact with the plane 20. The cycle ends. Thus, the axis of the shaft 10 makes a trajectory of 22-23-25 relative to the copier, and the burr removal occurs at section 23-24.

Copier 5 is adjustable in height to adjust the amount of deburring.
