Изобретение относитс к области машиностроени и может быть использовано при изготовлении топливной аппаратуры дизелей .-.The invention relates to the field of mechanical engineering and can be used in the manufacture of diesel fuel equipment.

Известно устройство дл ДОВОДКИ конического отверсти в детали, содержащее св занный с приводным двигателем iliapнирно установленный держатель детали и св занный с приводом враш,ени инструментальный шпиндель, установленный с возможностью осевого перемещени и соединенный посредством упорного подщипника и пружины с кулачковым вибратором 1.A device for the TRAINING of a conical hole in a part is known, which comprises an iliapedrically mounted part holder connected to a drive motor and a turner connected to a vrah drive, a tool spindle mounted for axial movement and coupled by means of an anvil support and a spring to a cam vibrator 1.

Однако известное устройство не обеспечивает достаточно высокой производительности и повышенного качества обр аботки вследствие ограниченной возможности повышени частоты вибрации шпиндел .However, the known device does not provide a sufficiently high performance and improved processing quality due to the limited possibility of increasing the frequency of vibration of the spindle.

Целью изобретени вл етс повышение производительности и качества обработки.The aim of the invention is to increase the productivity and quality of processing.

Эта цель достигаетс тем, что кулёчок вибратора выполнен с торцовой рабочей поверхностью, установлен на введенном в устройство подшипнике соосно шпинделю и св зан с. приводом вращени шпиндел , при этом вибратор снабжен установленным соосно кулачку с возможностью осевогоThis goal is achieved by the fact that the vibrator cup is made with an end-face working surface, mounted on a spindle coaxially inserted into a bearing device and connected with. the drive of the spindle rotation, while the vibrator is equipped with an installed coaxially cam with the possibility of axial

Устройство содержит стол 1,- инстру10 ментальный шпиндель 2, корпус 3 держател детали, св занный с педа1лью 4 механизма подъема (не показан). Инструментальный шпиндель 2 в корпусе 5 посредством клиномерной передачи 6 св зан с приводомThe device comprises a table 1, - an instrumental mental spindle 2, a body 3 of a part holder connected with a pedal 4 of a lifting mechanism (not shown). The tool spindle 2 in the housing 5 is coupled to the drive via a wedge gear 6.

Claims

15 7 rotations The pulley 8 through the flange 9 n key 10 is rigidly connected to the tool spindle. The spindle supports are bearings 11 with bushings 12, 13 and 14. The tool spindle from displacement 2Q is axially secured by a nut 15 with a lock washer 16. Inside the spindle, a rod 17 passes, which serves to unclench the collet 18 into which it is fixed. lap 19 interacting with workpiece 20. Pulley 21 is rigidly connected to cam 23 through a key 22 with a cam 23, the bearing of which is a bearing 24. A cam 23 at the end has three profile protrusions. The rollers 25 act on the thrust bearing 26 and are held in one position by means of a separator 27 into which three pins 28 are pressed in, which enter the slots of the flange 29. The cam 23, the bearing 24 and the separator 27 with the rollers 25 together form a cam vibrator. The tool spindle 2 is connected to the vibrator by means of a thrust bearing 26 and a spring 30. The part holder 31 is installed in the case 3 by means of a crosspiece 32. To prevent the part from turning during processing, a plate 33 of a material with a high coefficient of friction is designed. The part holder, the crosspiece and the housing are interconnected by means of axes 34 and 35 arranged in pairs in mutually perpendicular planes. The axle is prevented from falling out of the ring 36. With screws 37, the housing 3 is attached to a movable rod 38, which is driven by a driving motor (not shown) and raised by the pedal 4. An additional spindle 39 can be mounted in the device, which is driven by the engine 40, due to which it is possible to process the external cone of the part 41, for example, the priter 19 used to process the cone in the part 20. The part 41 rests on the supports 42 and is pressed against them by the roller 43. With spindle 39 it is connected with a clamp 44. The tool ntom is flat lapping 45. The apparatus operates as follows. After switching on the drive 7 (Fig. 2), the rotation is transmitted respectively to the pins 8 and 21. The pulley 8 via the flange 9 and the key 10 transmits the rotation to the tool spindle 2 with lap 19. The pulley 21 transmits the rotation of the cam 23 through the key 22. three rollers 25 rotating in the grooves of the separator 27 act on the bearing 26, which, through the flange 9, ensures the separation of the lap from the surface to be treated. To open the collet 18 when changing the lap 19, the rod 17 serves. Performing a vibrator cam with several protrusions on the working end and having a separate actuator for its rotation allows you to choose a rational oscillation frequency of the priter and thereby increase the productivity and quality of processing. A device for adjusting a tapered bore, comprising a pivotally mounted part holder associated with a drive motor and a tool spindle connected to a rotational drive, mounted for axial movement and connected to a cam vibrator by means of a thrust bearing and a spring, in order increase of productivity and quality of processing, the vibrator cam is made with an end working surface, mounted on a bearing introduced into the device but the spindle and coupled to drive rotation of the spindle, wherein the vibrator is provided with a cam mounted coaxially with the possibility of axial movement with the separator rollers finds schimis in contact with the working surface of the cam and the end surface of the thrust bearing of the spindle.
