Description

one

The invention relates to machine tools.

Devices for automatic tool changers are known. For cutting machines, there are two movable magazines with movable blades carrying tools whose axes are parallel to the axis of the assembly.

(The described device differs from the known ones in that the stores are installed on separate supports on opposite sides of the spindle head and are equipped with autonomous drives that provide alternate interconnected movement of both stores to the center pin and back. This simplifies the design of the machine, compactly placing it outside the working zones of necessary chi-layer of tools and shorten the cycle time of a tool change.

FIG. 1 shows the described device, front view; in fig. 2 - view “and the device from above; in fig. 3 is a section along A-A in FIG. one.

On the racks of the supports 1 there is installed a pulse head 2 with pinchings 3. To the right and left of it, on supports 4 and 5, there are tool shops 6 and 7 mounted on ball guides 8. Inside the shops there are carriages 9 connected in an endless chain. In the left part of the shop biv, the right part of the shop 7 is symmetrically mounted with drives for translational movement of shops and carriages consisting of

electric motors 10 with gearboxes 11. The carriages 9 are equipped with forks 12, in which tools 13 are laid. Rollers 14 and 15 of the carriages rest on rails 16 and 17.

When a signal is sent to a tool change, the pulse head 2 rises to the extreme upper position, and at the same time the spindle 3 moves in such a way that the juice of the tool holder 13 is

flush with the plug 12 of magazine 6, which is free at this moment. The magazine 6 moves along the guides 8 as far as it will go, while the fork 12 picks up the tool 13. At the same time, the command to spin

tool, and the spindle 3 moves to its highest position, freeing the tool cone. After the upper end position has been reached, the magazine 6 is reversed, at the end of which the magazine 7 moves towards the spindle, carrying a new tool in the fork of the front carriage 9. After stopping the magazine 7 in the leftmost position, a command is issued to lower the Spindle 3, the tool grip

clamp and its clamp. Then, the magazine 7 is retracted to the original (right) position. The next tool change cycle begins at the store side 7, which is now in the position of being ready to receive the spent

The tool is free. Until

The machining process is in progress, the carriages of the store B are moved from the electric motor 10 with the gearbox 11 until the carriage € 0 is installed in the readiness position for the change of the (front) carriage following the tooling program. After processing is completed, the tool change cycle is repeated.

Subject invention

Device for automatic tool change to machine tools, made in the form of two mobile magazines

with | movable | carriages carrying tools whose axles are spindle axles, characterized in that, in order to simplify the design, to compactly place the necessary number of tools outside the working area and shorten the tool change cycle time, the stores are installed on separate supports on opposite sides of the spindle head and are provided with autonomous drives that provide alternate interconnected movement of both stores to the spindle and back.
