Abstract

Usage: machine tool industry, namely, devices for drilling holes in large metal structures. SUMMARY OF THE INVENTION: the device is mounted on the workpiece 15. The handle 10 is in the off position, the magnetic flux is closed on the rack 1, and the chassis 19 is in the lowered position, which allows the device to move freely along the part 15. Using the lever 5 the drill head 4 moves down, the drill is fixed at the pivot point, and by turning the handle 10 by 180 °; the magnet is simultaneously locked onto the part 15 and the chassis 19 is lifted above it. After completing the drilling process by turning the knobs 10, the magnet is moved up to the off position, the chassis 19 is lowered and the device is ready to move to another processing position. 4 ill.

Description

AND

FIG. 7

The invention relates to machine tool industry and can be used to drill holes in large metal structures, in particular when drilling a thick steel sheet.

The purpose of the invention is to increase productivity by accelerating the movement of the device to another processing position.

Figure 1 presents a General view of the device; figure 2 is a top view; in Fig.3 - section aa in Fig.1 in the position of the magnet is turned off; figure 4 - section aa in figure 1 in the position of the magnet is turned on.

The device comprises a rack 1 with guide rails 2 placed on it, in which a movable plate 3 is mounted with a drill head 4 fixed to it, for supplying which there is a lever 5 connected with it with a fork 6 and a finger 7. The lever 5 is connected also with a stand 1 through an earring 8, which serves to transport the device with lifting means. The magnet 9 is controlled by the handle 10, which is set to the on or off position by turning 180 °. The handle 10 is fixed on an axis 11, which is connected to the magnet Z through the link 12 and the pin 13. by means of which the magnetic flux is closed to the rack 1 or through the base 14 to the workpiece 15.

At the ends of the axis 11, eccentrics 16 are mounted, interacting via clamps 17 and rods 18 with the chassis 19, which contain beams 2.0, at the ends of which swivel wheels 21 are installed, which serve to move the device along the workpiece 15.

The rods 18 are located in the guides 22, mounted on the rack 1.

The device operates as follows.

J

The drilling device is mounted on the pre-cleaned workpiece 15. The handle 10 is in the off position, the magnetic flux is closed on the rack 1, and the swivel wheels 21 are in the lowered position, which allows the drilling device to move freely around the part 15. When using lever 5 drill head

4 falls down, the drill is fixed at the pivot point and by turning the handle 10 through 180 °, the magnet 9 is simultaneously locked to the part 15 and the chassis 19 is lifted above it.

When drilling with the lever 5, the drill is fed to the desired depth and the drill is pulled out of the hole to remove chips.

At the end of the drilling process

the drill is removed from the machined hole, by turning the handle 10 the magnet 9 is moved up to the off position, by turning the axis 11 acting through the clamps 17 and rods 18 on

beams 119 with wheels 21. The device then moves to drill the next hole, after which the process is repeated.

Claims (1)

SUMMARY OF THE INVENTION A device for drilling, in the rack of which there is a magnetic element and rails designed to move the drill head, characterized in that, in order to increase productivity by accelerating the movement of the device to a different processing position, the device is provided with two chassis connected respectively to the last two rods, which are placed in the rack, and a handle connected to the rods and a magnetic element, which is a permanent magnet.
