Description

one

The invention relates to a machine tool industry, in particular, to automatic lines for machining parts.

Automated lines for machining parts with a transport system made in the form of a sectional conveyor with pushers and devices for the vertical movement of parts are known. However, the known devices do not allow parts to be mixed on two coats in any sequence, do not provide for centering parts during lifting, and have a complex drive.

The purpose of the invention is to simplify the design of the transport system devices.

To do this, in the proposed automatic line, each section of the conveyor is equipped with a drive link with stops that interact alternately with the pushers of both wheels, and the device for vertical movement of parts is made in the form of a carriage with centering strips located on both sides of the two-track conveyor and connected in series with each other. with a friend.

FIG. 1 schematically shows the proposed automatic line, a top view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. 1. 5 Automatic line is designed for

machining the hole and the end face of the wagon wheels.

The line contains metalworking machines 1 connected by a transport system,

consisting of a device 2 for removing and turning the wheels 3, a feeder 4, a sectional two-bay conveyor 5, devices 6 for vertical movement of the wheels 3, auto operators 7, devices 8 for mounting and

5 removal of wheels 3 on the machine 1, devices 9 for loading the wheels 3 on the lower rus of the conveyor 5 and conveyor 1O for dispensing the processed wheels 3 for pressing,

The machines of the 1 line are installed in two rows.

Claims (1)

0 The device 2 serves to remove the blanks of the wheels 3 of the overhead conveyor and tilt them (wheels) by 9 ° and is a lift with two carriages moving vertically away from the rope drives. The feeder 4 is made in the form of a double-row pushing conveyor and acts as a storage device between the device 2 and the conveyor 5, the sectional two-bay conveyor 5 is intended for transporting the wheels 3 on the line and consists of a metal structure 11 with two non-drive rollers (upper Russian 12 for wheel blanks , the lower rus 13 is for machined wheels between which a rod 15 with a pneumatic drive of reciprocating movement (not shown) is mounted on the rollers 14. The rod 15 is made of sections hinged with each other For example, the followers are installed (the followers 16 are for moving the wheels 3 on the upper tier 12, the followers 17 are for moving the wheels 3 on the lower runner 13) and a pull 18 with an electromagnetic drive 19 and stops (the stops 20 are for the tappets 16, the stops 21 - for pushers 18). The device 6 serves to lift the wheels 3 from the upper tier 12 of the conveyor 5 and consists of two vertically moving carriages 22 with centering bars 23 located on both sides of the conveyor 5 and connected in series with a rope 24 (or chain) each a friend and a pneumatic actuator 25. Auto-operation Op 7 is for trans. porting the wheels 3 from the conveyor 5 to the machine 1 and vice versa, and the device 8 - for mounting and removing the wheels 3 on the machine 1. The device 9 serves to unload the machined wheels 3 to the lower rus 13 of the conveyor 5, and the conveyor 10 - to issue the processed 3 wheels on the press. Limit switches (not shown) are installed on all devices and mechanisms of the line, and pneumatic actuators are equipped with an air preparation system and air distributors with an electromagnetic drive (not shown). The automatic line works as follows. Device 2 removes the wheel blank 3 from the overhead conveyor, tilts by 90 ° and transmits no quotation 4, which accumulates the blanks and transfers one to the top of the research institute Rus 12 koneeyer 5. Conveyor 5 transports the wheel blanks 3 to zones operation of the machine 1. The wheel blank 3 using the carriages 22 of the device 6 is lifted from the top sipysa 12, after which the auto operator 7 takes the workpiece and through the device 8 sets it to the machine 1 where the wheel is processed 3. After removing the wheel blanks 3, from the upper tier 12 of the conveyor 5, the next billet is supplied. First, the electromagnetic actuator 19 moves the tug 18 forward and the lugs 20 fix the pushers 16 of the upper tier 12. In this case, the stops 21 release the tappets 17 of the lower 13. Then the pneumatic drive of the reciprocating movement of the rod 15 is turned on. Since the pushers 17 of the lower tier 13 are not fixed, the movement of the wheels 3 on the lower tier 13 does not occur and a free space is formed there for supplying the machined wheel 3 from the machine 1. The machined wheel 3 is removed from the machine 1 by means of the device 8 and transferred to the operator 7, which transports the wheel to the loading device 9 on the lower rus 13 of the conveyor 5. Along the lower tier 13 of the conveyor 5, the machined wheels 3 are fed to the conveyor 10, which transports them for pressing. Claims of the invention Automatic line for machining parts like wagon wheels with a transport system made in the form of a sectional two-story conveyor with pushers and devices for vertical movement of parts, characterized in that, in order to simplify the design, each section of the conveyor is equipped with a drive go with stops, interacting alternately with the pushers of both Rus, and the device for the vertical movement of parts is made in the form of carriages with centering bars located along both sides of a two-light conveyor and connected in series with each other.
