Description

one

The invention relates to the field of mechanical engineering and can be used in the foundry industry.

At present, foundry processing, in most cases, is carried out manually.

At the Volzhsky Automobile Plant, an attempt was made to mechanize the processing of engine cylinder blocks from foundry bays. A device has been created for treating casting bays with percussion instruments and pneumatic actuators. A device that contains percussion instruments creates a lot of noise, which negatively affects the operating personnel.

A device comprising a base, a mechanism for feeding parts with an actuator, a housing in which a tool for punching holes and a tool for processing curvilinear surfaces, latches are known. The device is provided with elastic elements and a drive for a vertical feed of the body, which is installed on the base by means of elastic elements with the ability to move in a horizontal plane in mutually perpendicular directions and swing about a vertical axis. The tools are made in the form of a self-aligning tip and are placed along the perimeter of the housing, which

connected to the drive via a hinge

one.

Operation of the device has shown low productivity and inaccuracy of processing.

The listed bay handling devices do not work in an automatic cycle.

The purpose of the proposed invention is to automate the processing of bays of parts such as pistons.

To achieve this goal, a device is proposed, the machining tool of which is made in the form of paired, carrying knives, breakers that are hinged to the end of the lever through the traction and traverse. The lever is fixed on the rack between the stops with the possibility of rotation. The other end of the lever is connected to the drive. The device can be driven by an unloader, the visor which has a contact effect on the lever of the device. Knives breakers secured between the latches.

FIG. 1 - a general view of the device; in fig. 2 is a side view of the device on the casting machine accumulator; in fig. 3 shows an embodiment of the knives as one piece with the latches.

The device for processing bays of parts of the type of pigs consists of a support 1, on

the rack 2 is fixed to the rack. In the upper part of the rack there is a lever 6 attached to the rack by means of a spring 4 and stops 5, to which the yoke 7 is hingedly attached. On the frame there are machining tools made in the form of paired breakers 9 attached to the frame by means of hinges 8 which, through the glands 10, are movably connected to the crossmember. On the ends of the breakers fixed clamps 11, between which are placed the knives 12.

In order for the device to work in the automatic casting cycle cycle, the visor 13 is attached to the unloader of the latter, and the device support is attached to the accumulator 14 of the casting machine.

The device is driven by an unloader, the visor of which acts as a contact on the lever of the device.

The device works as follows.

During the movement of the machined piston 15 from the machine to the accumulator 14, the unloader with a visor 13 presses the end of the lever 6, which, moving between the stops 5, with its other end, using the crosshead 7 and the g 10, brings together a couple of breakers 9. During the approach of the breakers 9 the bay 16 occurs between the latches 11. With the final approach of the breakers 9, the gulf 16 of the treated piston 15 is removed with the help of the blades 12.

After removing the bay while moving the unloader for the next part, the lever 6, freed from the action of the visor 13,

under the action of the spring 4, it returns to the initial state.

The piston 15 is dropped into the container, and the next pair of pistons is fed to the accumulator 14 to process the bays.

The whole process of the device operation takes place in the automatic cycle of the casting machine.

The proposed device can operate without a casting machine from, for example, a hydraulic drive.

The proposed device reduces the labor intensity when processing casting bays of parts such as pistons by 6 times, freeing operators from heavy manual labor.
