Description

Известны ударные упрочнители галтелей валов, устанавливаемые на металлообрабатывающих станках.Known shock reinforcers shaft shafts mounted on metalworking machines.

Упрочнение галтелей вынолн ют методами обкатки роликами и шариками , а также чеканки с помощью нневматического ударника.The reinforcement of the fillets is carried out by the methods of running with rollers and balls, as well as by coining with the help of a pneumatic hammer.

Предлагаемое устройство дл  упрочнени  галтелей пр мых п коленчатых неподвпл ных валов методом чеканки состоит из разъемной муфты , на одной половине которой укреплен чеканочный пневмагкческий молоток, вращаемый вокруг щейки вала с помощью электродвигател . Такое устройство улучшает процесс чеканки и позвол ет производить упрочнепие валов, не занима  металлообрабатывающего станка.The proposed device for strengthening the fillets of the straight and crankshaft non-connected shafts by the embossing method consists of a detachable coupling, in one half of which a stamping pneumatic hammer is attached, which is rotated around the shaft shaft with an electric motor. Such a device improves the embossing process and permits the production of shaft hardening without occupying the metal working machine.

На чертеже показана кинематическа  схема предлагаемого устройства дл  внестаночного упрочнени  галтелей коленчатых валов.The drawing shows the kinematic diagram of the proposed device for extra-station reinforcement of crankshaft fillets.

Устройство состоит из разъемной стальной муфты /, пo ieщaeмoi на обрабатываемую шейку вала 2 с допусками, соответствующими ходово посадке. Две половинк г муфты скрепл ютс  между собой болтами. К одной из половинок разъемной муфты приварен шарнирный кронштейн , в котором укрепл етс  пневматический молоток 3. Боек молотка имеет сферическую форму с радиусом, равным ли близким к радиусу обрабатываемой галтели, и соприкасаетс  с галтелью, про.ход  через отверстие в муфте.The device consists of a detachable steel coupling /, that is, on the shaft of the shaft 2 to be machined with tolerances corresponding to the running fit. The two halves of the coupling are bolted together. A hinge bracket is welded to one of the halves of the detachable coupling, in which the pneumatic hammer 3 is fixed. The hammer head has a spherical shape with a radius equal to that of the processed fillet and is in contact with the fillet, passing through the hole in the coupling.

Корпус пневматического молотка располагаетс  в кропште Л е под углом в 45° к оси обрабатываемой шейки.The body of the pneumatic hammer is located in the pier of Le at an angle of 45 ° to the axis of the treated neck.

Разъемпа  муфта вместе с укрепленным на ней пневл:агическпм молотком приводитс  в медленное вращен 1е от электродвигател  4 через редуктор 5 и ременную передачу 6.The coupler coupler together with the pneumatic mounted on it: an agic hammer is driven into a slow 1e from electric motor 4 through a gearbox 5 and a belt drive 6.

При этом гибкий шланг, снабжающий инструмент воздухом, наматываетс  на вал (два-три нолных оборота муфты вокруг щейки) сначала в одном, 3 затем в обратном иаправленгиг.At the same time, the flexible hose supplying the instrument with air is wound onto the shaft (two or three full turns of the coupling around the cheek), first in one, then in the reverse and forward direction.

Во врем  вращени  муфты боек пневматического молотка наносит частые последовательные удары по галтели вала. От этих ударов остаетDuring the rotation of the coupling, the pneumatic hammer strike repeatedly hits the shaft fillet. From these blows remains
