The invention relates to the processing of metals by cutting, in particular to assemblies of automated machines, mainly small-sized, for horizontal drilling of bolts.

An object of the invention is to increase productivity in drilling horizontal holes in bolt heads.

This goal is achieved by the fact that in an aggregate automated machine for horizontal bolt drilling containing a bed, a work table with bolt-based devices and power heads connected by a single automatic control system in the form of spindle heads with drills installed in spring-loaded cups , clamping and orienting devices in the form of rolling pins mounted on a traverse in guides, and drives for vertical movement and rotation of rolling pins, automatic loading devices in ide vibrobunkera and two-armed robot, the presser-orienting devices disposed vertically, coaxially with the fixture bolts E for basing and above it, while their axes are perpendicular to the plane of the desktop, and Rolling Pin ends have hexagonal cavity mating with the bolt heads. In addition, the spring-loaded cups have annular beads, and the automatic control system comprises proximity sensors electrically connected to them and mounted on the outside of the spindles.

In FIG. 1 shows a machine, general view (front view); in FIG. 2 - general view of the machine (plan view); in FIG. 3 - bolt-based devices and pressure-orienting devices (general view); in Fig. .4 - drive for vertical movement and rotation of the clamping and orienting device (section AA in Fig. 3); in FIG. 5 is a transverse section of the end of the rolling pin of the clamping-orienting device (section BB in FIG. 4); in FIG. 6 is a device for protecting the drill from overload (section BB of FIG. 1).

Aggregate automated machine for horizontal drilling of bolts contains a frame 1, a working table 2 with devices 3 for mounting bolts mounted on it, power heads 4 for horizontal drilling, pressure-orienting devices 5, an automatic loading device, consisting of a vibro-hopper 6 and a two-armed robot 7. The strength of the head 4 is spindle head mounted on the worktable 2 in guides 8 for horizontal movement. The clamping and orienting devices 5 are located coaxially with the devices 3 for the base of the bolts and above them, with their axes being perpendicular to the plane of the working table 2. These devices are rolling rods 9 (see Figs. 3 and 4), which are mounted on the traverses 10. The traverses 10 can be moved along the guides 11, rigidly fixed on the table 2. The rolling rods 9 at the ends have hexagonal cavities 12 (see Figs. 4 and 5) mating with the heads of the bolts. There are also openings 13 for through passage of a headstock drill.

The clamping and orienting devices 5 are equipped with drives for vertical movement and rotation of the rolling pin 9. The drive for vertical movement is a pneumatic cylinder, the sleeve 14 of which

made integral with a rolling pin 9 and a traverse 10, and a piston 15 with a rod through a connecting strip 16 is rigidly fixed to the guides 11 (see Fig. 3). The rolling pin rotation drive is located on the crossarm and is a rack and pinion gear in which the gear 17 is rigidly mounted on the rotary part 18 of the rolling pin 9, and the gear rack 19 is integral with the rod of the pneumatic cylinder 20.

Bolt arrangements 3 consist of (see FIG. 6) guide exchange sleeves 21 mounted in the housing 22, and replaceable conductive bushings 23 for guiding the drill, also mounted on the housing 22, Replaceable drills 24 are fixed in the cartridge 25. which is installed in the spring-loaded cup 26 of the sleeve 27 of the spindle of the power head 4. The spring-loaded cup 26 has an annular

collar 23. A proximity sensor 29, electrically connected to the annular collar 28, is mounted on the outside of the spindle. Power heads, vertical drives, moving and turning rolling pins,

automatic boot devices

interconnected by a single automatic control system. The control system contains appropriate sensors monitoring the extreme positions of machine elements.

The machine has two working positions: the first one with one locating device 3 and one clamping and orienting device with a vertical displacement drive 5 and the second position similar to the first, but here the clamping and orienting device also has a rolling pin drive.

The operation of the machine during drilling, for example, of a hole in a bolt head followed by chamfering in this hole from two sides, occurs as follows:

In the initial position: the rolling rods 9 of the pressing-orienting devices 5 are raised to their highest position, and there is a gap (working space) between the ends of the rolling rods 9 and the bolt fixtures 3, the fixtures 3 of the first and second position of the machine have machined parts (bolts), spindle heads of power heads 4 with drills retracted to their original position (back). The first hand of the robot is against the first position of the machine, the second hand is against the second position. In this position, the control circuit instructs robot 7 to load and unload the machine. The second arm of the robot (see Fig. 2) removes the part (bolt) from the tool 3 to base the bolt of the second position of the machine, while the first hand removes the part from the device 3 of the first position of the machine. Both hands simultaneously move the parts one step so that the first hand of the robot 7 is opposite the second position of the machine, and the second hand of the robot is above the container for finished parts. Then the second dumps the finished part into the container, and the first hand loads the part processed at the first position of the machine to the second position. After that, the robot 7 moves the first hand and the second hand at the same time so that the second hand stops opposite the first position of the machine, and the first hand opposite the receiving tray of the vibration bin b. Then the second hand of the robot removes the part (bolt) from the first position of the machine, and the first hand removes the next part from the receiver of the vibratory hopper, after which both hands of the robot move and stop like that. so that the second hand stops opposite the second position of the machine, and the first hand opposite the first position of the machine. Then, both hands of the robot load the parts to the indicated positions of the machine, moving forward, after which they return back to their original position.

After both parts are installed in the bushings 21 of the devices 3 for basing on the first and second positions of the machine, a command is issued to the drives for vertical movement of the rolling pins 9 of both positions of the machine.

Compressed air is supplied to the pneumatic cylinders of these actuators, the cylinder rods moving the traverses 10 with rolling pins 9 down, mating the hexagonal cavities 12 (see Fig. 5 and Fig. 4) with the bolt heads. The corresponding faces of the heads of the bolts and the cavities 12 must be combined due to the fact that

lowering from above, rolling pin 9, in contact with the heads of the bolts, turn the bolt (orientate) around the vertical axis so that the faces of the bolt heads are in the same 5 position as the faces of the cavities 12 of the rolling pin 9, are in the corresponding position with respect to m drills 24. If this happens, the rolling pin 9 will lower to its lowest position, the bolt heads will be placed in 10 spaces 12 of the rolling pin 9, and the control circuit will command the power heads 4 to feed the drill. If the orientation of the faces of the bolt heads does not occur, the control circuit will give a command to re-elevate and lower the scanning of the rolling pin 9. And these operations will be carried out until then. while this orientation is carried out and the rolling rods 9 will take their extreme lower position, holding the parts in the fixtures 3.

0 The power heads 4, having received the appropriate commands, feed the rotary drill 24, moving the headstock along the guides 8 (see Fig. 1) towards the bolts being machined. With this drill

5 24 enter through the holes of the bushings 23 (see Fig. 6) and holes in the rolling pin 9, drill holes in the bolt head in the first position of the machine and chamfer in this hole on one side

0 in the second position of the machine. When the chamfer on the one side occurs at the second position of the machine, the drill 24 at the second position is retracted by the power head 4 of this position. After that, the turning pins of the rolling pins 9 of the second position of the machine are turned on. In this case, the rack gear 19 (see Fig. 4), moving the rod of the pneumatic cylinder, rotates the gear 17, and with it the rolling pin 9, which rotates the bolt in the sleeve of the fixture 3 by 180 °. The power head 4 is instructed to move forward, and the drill 24 chamfers the hole in the bolt head on the other hand. After that, drill 24 is retracted

5 backward, the rolling pin 9 in the second position rises to its highest position.

At the end of the process of drilling holes in the bolt head in the first position of the machine drill 24 power head 4 of this

0 position is retracted, rolling pin 9 of this position of the machine rises. The process of simultaneous processing at both positions of the machine is completed.

They give command to robot 7, and he hand 2

5 removes the finished part from the second position of the machine and throws it into the container, and by hand 1 removes the part from the tool 3 of the first position, transfers it and installs it in the same device of the second position of the machine. After which the process is repeated.

During the drilling operation at both positions of the machine, in case of increased load on the drill 24 (blunting of the drill, heterogeneous inclusions in the material of the part, skew, etc.), the spring-loaded cup 26, compressing the spring, moves back, while the annular shoulder 28 It is combined with a sensor 29, which gives a command through the control system to stop feeding the power head until the causes of increased load on the drill 24 are eliminated. Thus, the drill is protected from breakdowns (see Fig. 6).
