Abstract

The invention relates to the field of machine tool construction and can be used in multi-operation Tima machines processing center with mutually perpendicular arrangement of the spindle axes and tool magazine. The purpose of the invention is to simplify the design by reducing the number of engines. For this purpose, two pairs of mutually perpendicular rods 3, 4 and 5, 6 are mounted on the rotary body 1 on the rods. Brackets 7, 8 are fixed to the rods 3, 4, in which the rails 13, 14, bearing rods with tool grips are mounted. The rods 3, 4 and 5, 6 and the rails 13, 14 are moved with the help of the stem 37 of the cylinder 35. On the rod 37 there are two rollers which interact with the grooves made in the slide 9, 10 rigidly connected with the rods 3, 4 and 5, 6, and sliders, installed in the guide slide 9, 10. 1. f-ly, 12 ill. with (L

Description

belonging to the rails 13 and 14 respectively-45 occurs, since the grooves of length 1,

stately.

In the slide 9 and 10, in their guides, for example, like the dovetail type, sliders 29 and 30 are mounted with additional rails 31 and 32 interacting with the wheels 33 and 34 of the wheel assembly.

The rods 3, 4, and 5, 6 are moved by a power cylinder 35, which is rigidly connected to the housing 1. The cylinder 35 contains a piston 36 and a rod 37, passes w; through the guide hole in the housing 1 and the frame 2, extends it rigidity. On stock 37

parallel to the rod 37 and its movement. The slides 29 and 30 move together with the slats 31 and 32, interacting with the wheels 33 and 34 and the rotating wheels 11 and 12. The slats 13 and 14 with the grippers 19 and 20 first move to the distance 1. The grippers 19 and 20 come into contact with the tool hubs and the protrusions 21 and 22 of the rods 17 and 18 abut against the brackets 7 and 8. The rails 13 and 14 continue to move for a distance (H. At this time, the tool is unmounted in the machine spindle, and the forks 27 and 28 interact with jaws 23 and 24, which lock the necks of the tools. Rollers 39 and 40 at this time pass a distance of line 1y, and rails 13, 14 - distance 1 + (/. Then, the rollers 39 and 40 interact simultaneously with the grooves of length 1 and, as a result, the sliders 29 and 30 are fixed, and consequently the tool and they move together with slides 9 and 10, rods 3, 4 and 5, 6 and brackets 7, 8 to a length of 1, corresponding to the tool extension from the spindle and magazine slots and beyond the a-a plane (figure 1 to ensure safe rotation (nothing do not concern).

After that, the working medium is fed along the arrow M or H depending on where the rail 43 (Fig. 7) is located, and the rotary body 1 is rotated 180 by means of a gear-rack pair (rail 43 and the wheel 42) with the tools. Next, the working medium is fed into the rod cavity of dstindra 35. The rollers 39 and 40 are tracked back - first, jointly with the slots Ij of the sled 9 and 10 and the slots 1z of the sliders 29 and 30. The replaced tools are installed

in the nest of the spindle and the store, since 35 R this blocks gear wheels mouth

brackets 7 and 8 with grippers 19 and 20 are moved a distance of 1 in length. Then rollers 39 and 40 follow the grooves of length 1 and Ij. The slides 9 and 10 do not move, the slats 13 and 14 initially move to the distance cG, and the jaws 23 and 24 of the grippers 19 and 20 release the tool. At this time, the replacement tool is fixed in the machine spindle, and the grippers 19 and 20 move away from the tools to the distance 1, as the sliders 29 and 30 with the rails 31 and 32, moving, rotate the wheels 33 and 34 of the blocks. Wheels 11 and 12, interacting with the slats 13 and 14, return them to their original position. After that, the cycle can be repeated.

on the brackets, and in the latter, the guides, in which the grippers are placed, are made, and the power cylinder rod is provided with a roller, which is located in the copy and straight grooves of the sled and sliders.

2. The device according to claim 1, about t l and often because the cotton sponge is installed on an additional

The 45 injected rods with protrusions placed in longitudinal cavities made in rails, while the rods are spring-loaded with respect to the rails and arranged with their jaws to interact with the forks made on the rails, and the protrusions with brackets.

Invention Formula

1. A device for automatic tool changer comprising a housing, rotatable from the drive, on which a mechanical arm is placed with two grippers arranged to move in a mutually perpendicular direction at an angle to

the axis of rotation of the housing and the included spring-loaded sponges, as well as the mechanism for moving the grippers along the axis of rotation of the housing and their movement, having the main gear racks attached to the grips, connected by means of blocks of gear wheels with additional rails, and a power cylinder characterized by

In order to simplify the design by reducing the number of engines, the mechanism for moving each of the grippers along the axis of rotation of the housing and its extension is made in the form of a slide with guides, 25 arms and rigidly connected to the latter the slide is mounted in the housing with the possibility of their movement in the mutually perpendicular direction and made with locking grooves, and each slider is mounted in the respective guides on the slide, is made with a straight groove and is rigidly connected with the corresponding with additional rail

on the brackets, and in the latter, the guides in which the clamps are placed are made, and the power cylinder rod is provided with a roller placed in the copier and straight grooves of the slide and sliders.

2. The device according to claim 1, about t l and often because the cotton sponge is installed on an additional

the inserted rods with protrusions placed in longitudinal cavities made in rails, while the rods are spring-loaded relative to the rails and arranged to interact with their jaws with the forks made on the rails, and the protrusions with brackets.
