The multi-purpose portal machine comprises a base plate 1 (Fig. 1), two stands 2 located along the base plate 1. A portal consisting of carriages 3, racks 4 and a crosshead 5, on the guides of which two headstock are mounted with the possibility of movement 6 and 7 with sliders. 8 and 9.

On the continuation of the base plate 1, a tool magazine 10 is installed, which is a parallelepiped, on two opposite lateral surfaces of which there are holders 11 with the horizontal axis of the tool 12 (Fig. 3, 4), on the upper plane of the pair holders 13 with a vertical axis of the tool 14 are installed. Tool holders are fixed on the case of the magazine 10 with screws 15 (Fig. 5). The toolholders 11 and 13 have the same design and are only mounted in different ways to install horizontal 12 and vertical 14 tools. On the body of the holder, two jaws 17 are fixed with screws 16, having wedge surfaces 1Y (FIGS. 6 and 7), which interact with the gripping part of the tool mandrels made with the same wedge power joints. To center the tool in the holder, 1Pp is provided; and the key 19 is secured with a screw 20 which fits into the groove 21 of the tool holder 14.

To fix the mandrel of the tools 14, leaf springs 22 are provided in the holder, which are fastened by strips 23 and screws 24 to the jaws 17.

Shop overhead 25 contains a housing 26 mounted along the frame

2 from their outer sides to the foundation of the machine on which the plates 27 are installed for each head 28 separately The plates 27 are connected to the housing 26 by means of spring-loaded guide rolling pins 29 so that

the plate 27 can move relative to the housing 26, if in emergency situations, the slider runs across a predetermined amount of movement. ; ; ;

The overhead heads 26 (Fig. 1,2) are based on the plate 27 using the base strips 30 and the fingers 31. The design of the overhead head shops 25 mounted on the spruce and right sides of the machine is the same. The base plate 1 on the working surface has T-grooves for securing the satellite table 32 or the device for securing the grommets 33.

The machine operates as follows. , On the base plate 1 is installed

5, satellite table 32 with two identical blanks 33. The portal moves to the programmed coordinate to the tool magazine 10, the sliders 8 and 9 are lowered, heated up on the settings 14, stopped, the mandrels are clamped in the spindle and the bungee. The portal moves forward, while the springs 22 are moved apart, the gripping part of the mandrel of the tool 14 comes out of the jaws 17,

5, the movement of the portal is determined by the diameter of the tool 14 being removed from the holders 13. The sliders 8 and 9 are moved to the upper position and the portal is moved to the treatment area.

0 The installation of the tool 14 back into the magazine 10 after the cutting process is completed is as follows. The portal moves from the processing zone back to the magazine 10 to a predetermined coordinate, the sliders 5 and 8 are lowered down until the gripping part of the mandrels is against the jaws 17. The portal moves back and stops, while the springs 22 are moved apart by the mandrel, the groove 21 is centered0 a key 19, and the gripping part of the mandrel of the tool 14 enters under the wedge surface 18 of the jaws 17, which hold the mandrel in the axial direction, and the springs 22 press it against the side surface K

5 (Fig. 8).

The mandrel is pressed in the spindle. Each slider moves upward to release the tapering portion of the mandrel. The tool remains in the magazine 10. Next, the cycle repeats.

The change of overhead heads and tools in the heads is as follows.

The portal moves to a predetermined coordinate to the store of consignment notes, heads 25, at the same time headstock 6 and 7 are moved from the starting position in the middle of the crosshead 5 on the line of location of the store of the overhead head 25. The portal and headstock are stopped. The sliders 8 and 9 move down, stop, and the heads 25 are clamped at the ends of the sliders. The sliders 8 and 9 are moved to the upper position, at the same time the portal and the headstock 6 and 7 are moved to the specified coordinates and stopped above the tool magazine 10. The sliders 8 and 9 are moved down, the bikes 6 and 7 are moved to the tool, and are pierced by the head spindles 25 onto the taper shanks of the tools 12 and stop, clamping the tools in the spindles. The portal moves forward, the tools are removed from the holders 11, the portal moves to the processing zone, processing is performed.

The head 25 on the sliders 8 and 9 can be rotated 360 ° and fixed every 90 °, which allows to process all 4 vertical surfaces,

The tools 12 are inserted into the toolholders -1.1 of the magazine 10 in the reverse order.

Installing the overhead heads 25 in the overhead head magazine 25 is as follows; :

The portal from the processing zone moves to the shops of the overhead heads 25, at the same time the headstock 6 and 7 move along the traverse 5 on the head line and stop against the free places of the plates 27. The sliders 8 and 9 move down and stop. The overhead heads 28 are pressed, the heads are centered using the base strips 30 and the fingers 31. The sliders 8 and 9 are moved to the top:

henna position, stop, the portal moves to a predetermined coordinate to take the next overhead heads 28 and the cycle repeats.

The overheads 28 may be stored in stores 25 with a pre-installed tool, thereby improving processing productivity.

The proposed machine allows us to expand technological capabilities, increase productivity with full automation of the processing process, which is most achieved by simultaneous processing of two workpieces simultaneously with Two headstock.

Formula d & r etre and A multi-purpose machine with a movable portal, containing a bed, a fixed table, a beam, a headstock mounted on it, carrying a slider with a spindle, a tool magazine located at the end of the table; with sockets for the tool, and the spindles of rails are parallel to the axis of the spindle, which is installed with the possibility of interoperability with the tool, characterized in that, in order to expand technological capabilities, the machine is equipped with an additional headstock, similar to the main one, and shops of overhead heads, and the tool the magazine is made in the form of a parallelepiped, while on the upper plane of the latter there are nests, the axes of which are parallel to the axes of the spindles of the main and additional headstock, and at least on its two lateral planes nests are made, the axes of which are perpendicular to the axes of the aforementioned headstock, and the head-mounted magazines are placed along the bed from its two sides, and each of the spindles is mounted with the possibility of interacting with the corresponding head-mounted magazine and, with the latter, with a tool placed in the nests on the side plane x tool magazine.
