Description

one

The invention relates to mechanical engineering, in particular to hand-held drilling devices, and can be used to install and drill and similar portable tools directly at the work site.

The aim of the invention is to expand the technological capabilities of the drilling machine by combining the axial flow of the machine with the grip of the actuated product when the working fluid is pressurized.

FIG. 1 shows a nozzle with a manual drilling machine, FIG. 2 - a process of riveting parts; FIG. 3 is a view A of FIG. 2; FIG. 4 is a view B of FIG. 3; in fig. 5 is a sectional view BB in FIG. four; in fig. 6 shows the process of drilling the workpiece at an angle; in fig. 7, node I in FIG. 6, in FIG. 8 - section GG in FIG. 7; in fig. 9 shows the use of a nozzle for removing a bearing from a shaft; FIG. 10 is the same for centering shafts.

The nozzle for a hand-held drilling machine consists of a telescopic body, made like a pipe in a pipe and composed, starting from the inside, of movable sleeves 1 relative to one another, a team sleeve 2 with tabs 3, sleeves 4, In the sleeve 1 a hand-held drilling machine 5 with a chuck is installed 6, the fixed position of which is fixed with a clamp 7 with a screw 8 and a nut 9, the clamp 7 is connected to the sleeve 1 with a thread .. Depending on the process, a drill 10 can be installed in the cartridge 6 of the hand-held drilling machine 5 Drill 11, tip 12 or drill countersink 1 On the team sleeve 2 and the holder 4, there are eyelets 14-21, on which the clamps 22 and 23 are hingedly mounted with control rods 24 and 25. The tubes consist of a sleeve 26, a screw 27 and the nuts 28; On the gripper 23, it is installed adjustable on the thread of a nut 29 with a nut 30. In addition, a stud 31 is mounted on the clamp 23 with the nuts 32 and flags 33 and 34.

On the sleeve 1, the team sleeve 2 and the grip 23 marked scale 35 143382

Z-linear displacements. On the holder 4 there is a degree scale 39 with an arrow 40. On the hub 1 from the outside, and} ja of the holder 4 on the inside there are ortrules, which are equipped with annular grooves 41 and 42. team sleeve 2 on the inner and outer sides are also available

10 cylindrical beads, in KOTopjiix are made annular grooves, in which are installed threaded sealing rings 43 and 44. In addition, on the team sleeve 2 is installed

, lock nut 45. Sleeve 1 and the prefab g.pza 2 with the mating surfaces form rings of the cavity 46, and the assembled sleeve 2 with the holder 4 - the ring cavity 47. In the combined sleeve 2

20 and the casing 4 is made holes and installed fittings 48 and 49, connected to the source of supply of the working fluid (not shown). For the return movement of the sleeve 1 with the manual drilling machine 5 (between the sleeve 1 and the inner side of the collection sleeve 2) a spring 50 is installed.

For the return movement of the shimmer, Q we 4 (between the lock nut 45 and the cylindrical collar shoulder 4) are fitted with a spring 51.

The length of the feed stroke of the sleeve 1 with the hand-held drilling machine 5 depends on the distance over which the lower part of the collection sleeve 2 is screwed into the upper part, since the lower part of the collection sleeve 2 serves as an emphasis for the stroke of the sleeve 1. The larger the lower part of the assembly sleeve 2 to the top, the smaller the stroke length of the sleeve 1 with the hand-held drilling machine 5. The result of the length of the feed of the sleeve 1 with the hand-held drilling machine is obtained on a scale of 35, and the result of the thickness of the parts is on a scale of 36.

The angle at which the parts are drilled is indicated by the arrow 40 on the degree scale 39.

Nozzle to the manual drilling machine works as follows.

To perform drilling, zening and riveting of parts, install the grip 22 with the thrust 24 on the lugs 15

5- and 14, and the grip 23 with the thrust 25 - on the lugs 21 and 20, Spin nuts 28 t g 24 and 25, set the length t g r to set the grippers 22 and 23 s

nozzle on the rear corner of drilling details. In the chuck in the drilling machine 5, a drill-countersink 13 is installed, the drilling machine 5 is inserted into the sleeve 1 and fixed with a collar 7. The clamp 29 is set to a size that provides drilling of the part along the marking line, flags 33 and 34 on the pin 31 - equal to the step of drilling parts 52 and 53, and parts 52 and 53 - between the grippers 22 and 23; The working pressure is supplied through the nozzle 49 into the cavity 47, as a result of which the sleeve 4 is moved with the gripper 22 and the parts 52 and 53 are compressed. 5. Give the working pressure through the nozzle 48 into the cavity 46, in p The result is that the sleeve 1 moves with the hand-held drilling machine 3 to the parts to be machined 52 and 53. The results of the drilling depth, the detail engraving are obtained on a scale of 35, and the result of the thickness of details 52 and 53 is shown on a scale of 36. The angle at which the drill is drilled details, shown by an arrow 40 on a scale of degrees 39, Stretch the working pressure from the cavities 46 47. Under the action of the spring 50 and 51, the sleeve 1 with the hand-held drilling machine 5 and the sleeve 4 with the grips 22 and 23 move to their original position. Install the rivet 54 into the drilled hole. The nozzle with the hand-held drilling machine 5 is relocated by a step equal to the pitch between the rivets, for which the flag arrow must point to the hole made.

The working pressure is supplied through the nozzle 49B cavity 47, as a result of which the holder 4 is moved with the gripper 22, which under the action of pressure forms the closing head of the rivet 54. To perform the next cycle, including the operations of drilling, zening and forming the closing head of the rivet, will repeat the indicated operations.

To perform the centering operation of shafts intended for machining on a lathe in the centers, set the gripper 22 to the eyelet 16 or 17, and the gripper 23 to the

about tpina 20 or 21, t gu 24 - on the eyelet 15, and t gu 25 - on the eye 19. Install the centering drill 11 in the chuck 6 of the hand-held drilling machine 5, 5 in the chuck-1 and fix it with the clamp 7, and the nozzle pads 3 - at the end of the shaft 55, Serves the working pressure through the nozzle 49 in

the cavity 47, resulting in the movement of the cage 4 with tami 24 and 25 and grippers 22 and 23, which fix the shaft 55, Include a manual drilling machine 5, serves

the working pressure through the nozzle 48 into the cavity 46, whereby the bushing 1 with the handheld drilling machine 5 moves to the shaft 55 being processed. The result of the shaft centering is obtained on a scale of 35, the working pressure is released from the cavities 46 and 47, under the action of the springs 50 and 51 sleeve 1 with a handheld drilling machine 5, the sleeve 4 with clamps 22 and 23 are moved to the initial position,

To perform the removal of bearings 56 from the shaft 57, install T5 gripper 22 to eyelet 16 or 17, and gripper 23 to eyelet 20 or 21, weight of 24 and eyelet 15, and load of 25 to eyelet 19, install into the sleeve 1 tip 12, the diameter of the shank

equal to the diameter of the body of the handheld drilling machine 5 and fixed with its clamp 7, the working pressure is fed through the nozzle 49 into the cavity 47, as a result of which the movement occurs

sleeves 4 with shafts 24 and 25 and clamps 22 and 23, which fix the bearing 56, supply working pressure through fitting 48 to cavity 46, as a result of which sleeve 1 moves

with a tip 12, which under the action of force will press the shaft 57 from the bearing 56,

Compared to the known, the proposed attachment allows simultaneous drilling, countersink with automatic feed and riveting of parts, only drilling with automatic feed or only riveting of parts, centering of shafts, removal of bearings from the shaft.
