(54) TOOL STORE

The invention relates to the field of machine tools and can be used in multi-tool machines with automatic tool change.

A drum-type tool magazine is known for machine tools with an automatic tool change that contains elements of axial and radial fixation of tool holders Cl.

The disadvantages of the known tool shop are reduced accuracy of the radial fixation of the tool mandrels, due to the fact that the radial fixation elements are located in the sleeves that are movable relative to the magazine, the gap between them and the magazine introduces additional error in the base of the mandrels, as well as associated with the need to manufacture and install movable sleeves and ensure their interaction with the power drive.

The purpose of the present invention is to improve the accuracy of the radial fixation of the tool, as well as to simplify the design and technology of the shop.

To achieve this goal, the radial fixation elements are made in the form of sleeves fixed on the shop with two centering sleeves, and the axial fixation elements are made in the form of a stationary di-fcKa interacting with the flanges of the tool holders. The disk is provided with a spring-loaded plate with a drive for its movement and has a groove in which the above-mentioned bar is installed.

In FIG. 1 shows a tool magazine, a section; in FIG. 2 is a view A of FIG. 1 (guide and mt conditionally removed); in fig. 3 shows a section BB in FIG. one .

The drum type tool magazine consists of a rotating clock 1 mounted on bearings 2 on axis 3. Axis 3 is fixed on plate 4, through which the magazine is attached to the machine. On the rotating part, the radial fixation elements are made in the form of a sleeve 5 with two centering points for the radial fixation of tool mandrels.

A disk 6 is fixed on axis 3, providing axial fixation of instrumental mandrels. The disk b in the position of the tool change has a rectangular groove 7, the overlap of the movable plate Ko; i 8 mounted between the guides 9 and 10 fixed to the disk 6, In the plank 8, the axle 11 passes through the through window through to the guide 10. Under the action of the spring 12, the strip can be displaced to the periphery of the disk 6 until the axis 11 stops against the end of the through window in the guide 10. At the same time, the front end of the strip 8 forms a common closed surface with the disk 6 using an axle 13 on with a power drive 14, which is used as an electromagnet .rjHytn.Ggo tpg, s akreplenig;, nd on b. I1KGG1 y;, r4iTajib n.je gmgranka 15 install ntov in the store so that they are fixed by the centering bits of Btulok 5, and in the axial direction by the disk b. On the left (in the drawing) of the instrumental. the mandrel 15 is located the gripping portion of the mechanical arm 16, which directly implements the tool change. The drive of the enemy part of the magazine and the mechanism of its fixation in the position of the tool change are not shown in the drawing. The shop works as follows. By means of the drive of the rotating part of the magazine and the mechanism of its fixation, the illuminating part of the magazine is turned into a fixed position set by the software. At the same time, the instrumental mandrel stops at the tool changer position on the bar 8, which is to be changed. The mechanical arm moves as it moves. vatulvaet instrumental mandrel from its flange. At the end of the acquisition, the actuator 14 is turned on, which, through mt 13 and axle 11, shifts the bar 8 to the center of the disk b, releasing, and then caMbiTvi inot the axial fixture of the cage. The spring 12 is in this case supplied. The mechanical arm pulls the tool from the magazine and inserts the mandrel from the magazine and inserts the gas in a 180 ma after the turn on the gas and the tool comes in: a to y, s g thuja from spindle. After that, the actuator 14 is turned off and the bracket 8 is moved by the action of the spring 12 to the initial position, fixing the tool. The mechanical adjustment in the axial right hand by moving in the direction of the arrow B returns to the initial position, and the tool change cycle is completed.
