(54) УСТРОЙСТВО ДЛЯ ШЛИФОВАНИЯ(54) DEVICE FOR GRINDING

II

Изобретение относитс к машиностроению, в частности к устройствам дл выполнени шлифовальных, а также полировальных работ эластичным инструментом.The invention relates to mechanical engineering, in particular, to devices for carrying out grinding, as well as polishing work with an elastic tool.

Известны устройства, содержащие вращающийс щпиндель и механизм осциллировани , в котором дл сообщений осевого возвратнопоступательного движени используетс кулачковый пазовый механизм и ременна передача с двум шкивами, насаженными на один вал и имеющими разные диаметры 1.Devices are known that contain a rotating spindle and an oscillation mechanism in which a cam groove mechanism and a belt drive with two pulleys mounted on one shaft and having different diameters 1 are used for axial reciprocating movement.

Вращение передаетс от отдельного привода , .через общий щкнв-муфту, на шкив щпиндел . Дополнительный шкив, надетый на втулку с пазом, име иной диаметр по сравнению с первым щкивом, сообщает через палец возвратно-поступательное движение шпинделю.The rotation is transmitted from a separate actuator, through a common push-in coupling, to the pinch pulley. An additional pulley, worn on a sleeve with a groove, having a different diameter compared to the first one, imparts a reciprocating movement to the spindle through a finger.

Величина возвратно-поступательного движени шпиндел зависит от паза во втулке, возможность регулировки хода и усили поджати инструмента к изделию исключаетс .The magnitude of the reciprocating movement of the spindle depends on the groove in the sleeve, the possibility of adjusting the stroke and the force of the tool against the product is excluded.

Использование ременной передачи увеличивает габариты н вес устройства, что ограничивает его использование, так как оно можетThe use of a belt drive increases the size and weight of the device, which limits its use, as it can

бьгть применеИо только в стационарном оборудовании .Be used only in stationary equipment.

Целью изобретени вл етс упрощение конструкции н расширение технологических возможностей устройства.The aim of the invention is to simplify the construction and expansion of the technological capabilities of the device.

Дл этого устройство снабжено кронштейном , шарнирно св занным с корпусом, и упругим упором, установленным между корпусом н кронштейном, а механизм возвратно-посту7 нательного перемешени шпиндел вьшолнен в виде шестерни-кулачка, закрепленного на валу привода с возможностью упругого контакта со шпинделем, дл чего в устройство введена пружина, св занна со шпинделем, при этом привод вращени шпиндел выполнен в виде двух пар зубчатых передач, кинематически св зывающих приводной вал со шпинделем.For this, the device is equipped with a bracket pivotally connected to the housing and an elastic stop mounted between the housing and the bracket, and the spindle is reciprocating and post-shuffling in the form of a gear-cam mounted on the drive shaft with the possibility of elastic contact with the spindle, for which A spring connected to the spindle is inserted into the device, while the rotational drive of the spindle is made in the form of two pairs of gears, kinematically connecting the drive shaft with the spindle.

Claims

In case 1 a quill 2 is mounted for reciprocating movement in which spindle 3 is mounted. A flange motor 5 is fixed on flange 4, the shaft of which is connected to intermediate shaft 6 carrying gear-cam 7. Gear spindle 8 is seated at the end of spindle 3, large in comparison with the gear-cam 7. Both gears are kinematically connected through a shaft-gear 9. The gear 7 is equipped with a contact roller 10, which is pressed by a spring 11 to the gear-cam 7. A thread is made on 2, on which the adjusting nut 12 is obstructed .Cor The trigger 1 is hinged to the bracket 13. Between them is located a spring shock absorber 14. The device operates as follows. From gear-cam 7, the rotation is transmitted to shaft-shaft 1 of day 9, which engages with gear 8, mounted on spindle. Gear 8 has more teeth than gear-cam 7. Thus, the difference in the number of revolutions between them and the possibility of providing back - by stepwise movement of the quill 2 due to the elastic interaction of the roller 10 with the cam 7. The hinged attachment of the body 1 to the bracket 13 and the presence of a shock absorber 14 provide a soft, elastic movement of the tool along the surface of the product, creating Enhance the adjustment of the force of the polishing wheel and the processing of both smooth and relief surfaces. Combining the gears and cam mechanisms in one kinematic scheme allows us to simplify the design, reduce the size and weight of the device, make it compact and versatile. Claims An apparatus for grinding, comprising a housing, a spindle with a drive for turning it, and a mechanism for reciprocating movement of the spindle, characterized in that, in order to simplify the design and expand the technological capabilities, the device is provided with a bracket pivotally connected to the housing and an elastic stop mounted between the case and the bracket, the mechanism of the reciprocating movement of the spindle is made in the form of a cam-cam) fixed on the drive shaft with the possibility of elastic contact with the spindle using the spring connected to the spindle, which is inserted into the device, with the spindle rotating the drive in the form of two pairs of gears, kinematically linking the drive shaft with the spindle.
