Description

I

FIELD OF THE INVENTION The invention relates to machine tools), namely to multioperational machines with automatic change of satellite equipment.

Closest to the proposed technical solution is a multioperational machine with an automatic change of satellite devices, containing a column with a spindle head, a coordinate table and a mechanism for changing the accessories of satellites p}.

The disadvantage of the known machine is a considerable time to change the pallet.

The purpose of the invention is to increase the productivity of the machine.

The goal is achieved by the fact that the mechanism for changing satellite devices is equipped with a carriage and is made in the form of two adjacent parallel branches of a chain conveyor connected on one side by a carriage installed

with the ability to move perpendicularly to these branches, and on the other hand, the coordinate table, with drive chain sprockets. the conveyor belts are located in the zone of coordinate movements of the table, while the satellite devices are equipped to transfer satellite devices from the chain conveyor to the machine coordinate table

10 lever with sprockets, installed with the possibility of engagement with the drag chain of the conveyor.

FIG. 1 schematically shows the proposed machine, a general view; on

Based on 1, go

20, the coordinate table 2 is moved to, which is fitted to fit-fit 3 with the workpiece. A spindle head 5 is mounted on the column 4 above the table. Next to the base 1 there is a chain conveyor made in the form of two branches 6 and 7 with directions 8, on which the devices 3 are placed. The drive of the transport is carried out from the gearmotor 9 through chains 10 through sprockets 11, on the frame of branches 6 and 7 a hydraulic cylinder 12 is displaced by a carriage 1 3; In case 14 of a fixture-satellite 3 on an axis 15 a lever 16 is fixed carrying sprockets 18 that are free to sit on an axis 17 19 washers Already 20, the stroke of which is limited by krppko 2. The adjusting screw 22 serves to adjust the position of the lever 16. The propeller sprockets 23 of the conveyors 6 and 7 are located in the zone of the table 2 movement. The proposed machine works as follows. At the beginning of the cycle of the machine dinate table 2 is moved to conveyor branch 6 by a command. At this time, the corresponding motor-gearbox 9 is turned on, and the chain 10 begins to move. When all the fixtures-satellites are on the conveyor, all the sprockets 18 engage with the drive chain 10. Thus, as the chain moves, and the fixtures-satellites stand either completely or each stop, the sprockets 18, which are free on the axis 17, rotate about this axis. When the coordinate table 2 arrives at the load, the sprocket 23 of the branch 6 of the conveyor is in the table area, and as soon as the command removes the stop (not shown), which holds the extreme satellite device 3, it gets a further opportunity, since only the effort of the stop, exceeding the setting of prulsna 20-, this spring, clamping the stars daughter 18 with washers 19 to axis 17, fixes an asterisk on this axis, and with method-satellite 3 together with chain moves to the coordinate table 2, lever 16 this pallets on teams is rotated about the axis 15 is withdrawn from the chain sprocket 10, 14 and a coordinate table 2 with a device-satellite goes into the working ozitsiyu, where the details of processing. this time, all the satellite accessories located on both branches of the conveyor are moved one step further, with the extreme one being adapted. a satellite on branch 7 of the conveyor adjacent to the carriage 13, along the guides of the conveyor, slides onto the guide carriages. In the machine cycle, the hydraulic cylinder 12 is turned on, the satellite adjustment carriage moves to the conveyor branch 7, where the asterisk of this satellite attachment engages with the moving drive chain. Due to this, the satellite device moves the space left free as a result of moving satellite devices on the conveyor belt, and all the satellite devices on the conveyor branch 6 stop at the stop, and the carriage 13 returns to its original position. located on the coordinate table 2. When the machining of the part ends, the command table moves to the position where the sprocket 23 of the conveyor branch 7 is in the coordinate zone displacements of the table. On cdmand, the satellite access lever 16 with the machined part is lowered and its sprocket engages with the moving drive chain of the conveyor branch 7. As a result, the satellite, which is unlocked on the coordinate table 2, moves to the conveyor branch 7, and the coordinate table itself goes to the load with the next satellite. After that, the cycle repeats. Thus, the proposed multioperational machine works without the operator’s participation until all the parts loaded initially along both branches of the conveyor are processed, and with the appropriate extension of these branches the automatic processing process lasts a long time.
