(54) DEVICE FOR DRILLING HOLE

I

(57) The invention relates to a machine tool industry, in particular, to devices for drilling a group of holes in parts without prior marking0. The aim of the invention is to expand the technological capabilities. In the replaceable conductor plate 1 in the form of a disk 2, radial pass-through slots are made under the corresponding parts corners In the additional disk 7 there are a series of mounting holes 8 for installing conductor sleeves with them on the flats on one of the

end face Another end of the conductor sleeves is in contact with the lining 15 "On the shank of the conductor plate 1 there is a T-shaped groove in which the device orientation mechanism is installed relative to the end of the workpiece 12" The orientation mechanism contains the sleeve 17, the eccentric 19 and is rotatably mounted around the axis of the sleeve 17 the stop 20 with two asymmetrical support surfaces. Depending on the size of the workpiece, the surface of the stop 20 contacting with the end surface of the part 12 is mounted on an The distance and fastening is fixed. At this, the eccentric 19 is set to the middle position, which makes it possible to move the stop 20 through the T-shaped groove 160 when changing the workpieces. Then the device is superimposed on the part 12 and the holes 1 1 Il are machined.

The invention relates to a machine tool industry, in particular, to devices for drilling a group of holes in parts without prior marking, circumferentially or in the rectangular coordinates of the relative central base hole in parts of the body, panel, and associated flanges, sockets. - max, covers, and can be used in machine building

The purpose of the invention is the expansion of technological capabilities,)

The figo shows the overhead conductor, front view, section, ft, an example of a specific implementation of the proposed conductor for drilling 2S 4, 8 holes symmetrically circumferentially or set in rectangular coordinates, based on the central bore (hole ) in the rectangular blank) n-afit.2. top view of figure 1; figoZ - section aa on figo 2 (conductor sleeve assembly); FIG. 4 is a bottom view of FIG. O1; FIG. on fig5 - plate, front view, section; FIG. 6 is the same, bottom view of FIG. 5, FIG. 7 is a section BB of the fig (U-shaped slot is shown); Fig, 8 is a section bb In Fig (shown T-shaped groove); Fig - additional disk 7; Fig 10 - lining 15; FigoP is an embodiment of the plate 1 (grooves after 60)

The device contains a replaceable plate 1 in the form of a disk 2 with a shank ZS. In the disk 2 there are radial through grooves 4 located under the corners corresponding to the workpiece, and in the center of the disk 2 there is an exact mounting hole 5 for installing the sleeve 6 serving as a base element for an additional disk 7 with a number of installation holes 8 for installing conductor sleeves 9 with strips in them 100 All groups of holes 8 are provided with numeric characters 11 corresponding to the center distance in the workpiece 12, the additional disk 7 is pressed by means of a base disk 13 and a screw 14 with a lining 15, which serves as a stop against axial displacement of the conductor sleeves 9, which contact the lining 15 with their lower ends IO On the replacement plate 1 on the shank 3 there is a T-groove 16, employee for installing a mechanism on it

The orientation of the part 12 is perpendicular to the longitudinal axis of the groove 160. The orientation mechanism comprises a sleeve 7 rigidly connected to the plate 1 by a bolt 18, an eccentric 19 mounted rotatably around the axis of the sleeve 17, an emphasis 20 mounted with the possibility of reciprocating displacement along the longitudinal axis of the groove 16 under the influence of the rotation of the eccentric 19 to compensate for the error in the manufacture of the workpiece. The stop 20 is kept from being twisted by the keys 21, rigidly fastened to the stop 20. In this case, at the stop 20 s two unsymmetrical abutment surface In addition, the orientation mechanism is pivotally mounted anvil 20 by 180 ° during the changeover of the conductor for the purpose of using different basing abutment surface 20 (Figure 5) - left or right - depending on the size of the workpiece.

For orientation of the base disk 7 relative to the workpiece 12, plate 1 has a central II-shaped groove 22 passing through the entire disk 2, with the axial axis of the U-shaped groove 22 coinciding with the longitudinal axis of the T-shaped groove 160

The D-shaped groove 22 serves to install a retainer 23 in it, terminating with flips, in contact with the U-shaped groove 22, the cylindrical part of the retainer 23 fitting into one of the mounting holes 8 of the disc 7 o

The device is set up as follows.

Select a basic disk 7 from the set of replaceable disks, corresponding to the workpiece, with the numeric sign 11 (the number indicates the center distance between the holes of the part), install guide sleeves 9 and install sleeve into the other holes of the basic disk 7, and set in such a way that the flats 10 on the conductor sleeves 9 entered the grooves 4 on the disk 2 of the plate 1 "

After that dock the Central hole 5 in the disk 2 of the plate 1 with the sleeve 6 and together with the lining 15 of the base disk 13 is pressed against the interchangeable plate 1 by means of a screw 145
