Description

one

The invention relates to metal cutting.

: A machine tool with an automatic tool changer is known, in which tool fixing is carried out autonomously by means of a disk magazine, mounted on vertically slides mounted above the spindle head and carrying spring-loaded levers with clamps. When changing tool blocks, rigid reciprocal guide guides are required for placing the blocks and the corresponding block guides, write a required clearance when pulling the block onto the caliper between 1 guide, which can get into the body and other foreign objects.

This complicates the design, since it is necessary to use special devices for cleaning the clamping surfaces and to perform an automatic check on the accuracy of their fit: in addition, when installing the device, it is necessary to carry out labor-consuming fitting works. of the block are blocked in the form of U-shaped elastic elements, which are classified in series in one row of fixed

base to the store and having a side lug along the length of the element at the end of each shelf. In addition, each protrusion of the elastic element of the installation mechanism has a section, perpendicular to the base and an element shelf, a V-shaped depression facing the other shelf of the element, and each protrusion of the elastic element of the fixation mechanism has a section, parallel to the base of the element, of a trapezium facing verist outward.

This simplifies the design and improves the cleaning of guide rails and tool blocks.

Application of U-shaped elastic elements

provides the thrust of the block on the caliper without a gap (with a strain), which allows to clear the support guides and the block-based guides from foreign objects, and also there is no need for fitting work when mounting the device on

machine tool.

FIG. 1 shows the device, the general view; in fig. 2 is the same, section L-A in FIG. I in FIG. 3 is the same section B - B in FIG. 1 (installation mechanism); in fig. 4 is the same permission :) B-B to

FIG. 2 locking mechanisms; in fig. 5 - the same.

RGI of GG in FIG. 4 protrusions mehashzma fixing; in fig. 6 - the same, top view.

The device comprises a housing 1, a magazine 2, drives -3 N 4 moving the case and the magazine, mechanisms 5 and 6 of the installation and fittings 1; the tool blocks 7. The mechanisms of fixing the blocks 7 are executed in the form of n-cSpasiiWK) elements of the same size | fixed, I agree, u bases 8 and 9 to the store with 2 screws W. According to the elastic element of the mechanism 5

The installation at the end of each shelf II has an outer lateral protrusion 12, having, in cross-section, a perpendicular-;

on the base 8 and shelf P, V - shaped, hollowed, turned with the base to another shelf of the elastic element.

Along the length of the elastic element | mechanism b HOSKHiy K01, each shelf 13 has a bead joked protrusion 14, having a cross section parallel to ocnoBaifflio 9 of the elastic element, the form of transes, My face facing outwards.

The device works as follows.

In order to remove the screwed-in unit, mounted and mounted on the guide rails 15 for the base units of the standard units, the device is moved by the actuator 3 to the support in the direction indicated by the arrow D. (see Fig. 2 and 6). :

At the same time, the lateral protrusions 12 and 14 respond-1 of the external elastic elements of the mechanisms 5 and 6 of the installation and fixation run over the y-shaped guides 16 of the block 7 until the lateral projections 14 of the elastic element of the fixing mechanism 6 drop into the center of the first grooves 17 in guides 16 of block 7, fixing the tool block in the magazine. The device has stopped; The block 7 is detached from the guides 15 of the caliper for the base structural blocks and the device together with the block 1 sitting on the elastic elements returns to the original polo. life, I

After that, the drive 4 turns the magazine 2 in; the installation of the new block 7, the device moves to the caliper, the block 7 advances with its guiding rails 18 onto the control bars 15 of the caliper, the device stops, the block 7 is fixed to the support and the device starts moving in the opposite direction. At this moment, the lateral protrusions 14 of the elastic element I of the fixation mechanism 6, due to the presence of 1 SHH bevels and the elasticity of the shelves 13, expelled from the central grooves of the G / in the guides 16 of block 7, fixation of the IiCtpy semt - vlЮгOO block 7 in store 2 stops and the device returns to the starting position.

With the longitudinal thrust of the block 18 block guides on the slide rails 15, they are mutually cleaned of foreign objects due to the external effect of the lychisms 5 and 6 of the set and fixation of the block 7.1

The base unit 18 block 7 and the BHHromiie caliper 15 for the base of the tool blocks are positioned so that when you hit the block 18 block on the direction, the block 15 elastic elements of the mechanisms 5 and 6. of installation and fixation are deformed as a result of block 7 direction, perpendicular to p; the direction of movement of the block on the caliper, and because of this, the latter remains stationary in this direction. At the same time, the elastic elements of the Bod mechanisms 5 give the guides 18 to the guides 15 with a force allowing the first guides to move along the second ones.

In this case, the displacement of the end of the block 7 displaces the objects from the guide rails, and the end of the guide rails 15 of the slide displaces foreign objects from the guides 18 of the block 7 and thus mutual cleaning of the guides 11Д1 | x 15 and 18.
