Description

Изобретение относитс к станкостроению , преимущественно к устройствам замены шлифовальных кругов на торцекруглошлифовальных станках.The invention relates to a machine tool industry, primarily to devices for replacing grinding wheels on round-grinding machines.

По основному авт. св. № 596414 известно устройство дл замены шлифовального круга, зашищенного кожухом , шарнирно соединенным с крышкой, выполненной в виде двух шарнирных створок, на одной из которых установлены механизм захвата и механизм перемещени шлифовального круга с план- шайбой 1.According to the main author. St. No. 596414 discloses a device for replacing a grinding wheel encased with a casing hinged to a lid made in the form of two hinged flaps, one of which has a gripping mechanism and a mechanism for moving the grinding wheel with a washer 1.

Недостатком указанного устройства вл етс невозможность размещени шарнирных створок кожуха шлифовального круга на современных скоростных торце КРУ глош;7ифов ал ьных станках в св зи с упором их в стол несуаий бабки издели . Кроме того, отверсти , выполненные в планшайбе шлифовального круга, ухудшают услови демонтажа в св зи с необходимостью поворота планшайб дл совмещени отверстий с зажимными винтами механизма захвата. Выполнение крышки кожуха в,виде двух шарнирных створок ухудшает работу , р еханизма перемещени шлифовального круга. Во врем замены шлифовального круга нарушаетс соосность выжимной п ты и шпиндел , что может привести к -заклиниванию механизма перемещени .The disadvantage of this device is the impossibility of placing the hinged flaps of the grinding wheel casing on the modern high-speed end faces of the switchgear assembly in combination with their machine-tool in relation to the table on the table. In addition, the holes made in the faceplate of the grinding wheel worsen the dismounting conditions due to the need to rotate the faceplates to align the holes with the clamping screws of the locking mechanism. Making the cover of the casing in the form of two hinged flaps impairs the operation of the grinding wheel movement mechanism. During the replacement of the grinding wheel, the coaxiality of the release pin and the spindle is disrupted, which can lead to jamming of the movement mechanism.

Целью изобретени вл етс повышение эксплуатационной надежности устройства. The aim of the invention is to increase the operational reliability of the device.

Дл этого крышка снабжена щарнирным рычагом, установленным между For this, the cover is equipped with a hinged lever mounted between

10 створками, а створка, на которой установлены механизм захвата и механизм перемещени шлифовального круга с планшайбой, снабжена шарнирно-рычажным упором, причем на планшайбе выполнена кольцева канавка, с которой 10 flaps, and the flap, on which the gripping mechanism and the mechanism for moving the grinding wheel with the faceplate are installed, is equipped with a hinged-lever stop, with a ring groove with which

Claims

The device comprises a casing 1, hingedly connected with a cover made in the form of a flap 2, a lever 3 and a flap 4. On the flap. 2 are mounted a gripping mechanism, made in the form of two hinged-lever clamps 5, interacting with the annular groove of the faceplate 6, and a moving mechanism, made in the form of screws, heels 7, as well as a hinged-lever stop 8 for supporting and installing J Ki faceplate 6 shpfovalovogo circle. The washer b is fixed with a nut 9 on the spindle 10. The device works as follows. When the grinding wheel is removed, the fasteners securing the flaps 2 and 4 and the lever 3 of the cover are released to the skin 1, and the nut 9 is screwed in (pin 10). Then the clamps 5 are inserted into the ring channel of the faceplate 6 and fixed with screw clips. the faceplate B is guided by an abutment 8 and secured with a screw clamp.Then, using the screw bar 7, the faceplate b is removed from the spindle 10. By turning the hinged flaps 2 and 4 and the lever 3, the faceplate b moves coaxially to the axis of the spindle 10 and is moved outside the machine where the worn grinding circle lane is loaded onto the transport cart and a new circle is put in its place .. The installation of a new circle on the spindle 10 proceeds in the reverse sequence of the circle removal. In the proposed device, the introduction of a pivotal-lever support facilitates the installation and orientation of the circle relative to the pivot-lever grippers. An annular groove in the faceplate of the circle speeds up the process of coupling the circle to the cover of the casing. Due to the three-part cover of the casing, there are no distortions of the circle's faceplate relative to the spindle. The invention The device for replacing the grinding wheel on the author. St. 596414, characterized in that, in order to increase the operational reliability of the device, the lid is provided with a hinged lever installed between the doors, and the sash, on which the gripping mechanism and the mechanism for moving the grinding wheel with a faceplate are installed, is equipped with a hinge-lever support, and there is an annular ring on the faceplate. groove for engagement with the grinding wheel grab mechanism.
