Description

The invention relates to the field of metalworking and can be used for automatic loading of machine tools with workpieces and removal of finished parts after their processing.

A device for loading a metal-cutting machine, containing a magazine with orienting cells formed by plates, and an auto-operator [1]. An auto operator carries two pivot points around a common grip axis with clamping fingers. In order to provide the possibility of supplying the grip fingers to the workpiece when they are tightly located in the store in the plates of the latter in the direction of the axes of the prisms, grooves are made for an easy passage of the grip fingers.

However, when installing workpieces of different diameters, readjustment of plates and prisms of cells is required. Otherwise, either the workpiece will fall down (will not be oriented), or it will not enter the cell. In addition, the magazine has a certain number of cells, and the same number of blanks can be loaded into it, regardless of their length, even if the length of the part is much less than the length of the cell along the axis.

The aim of the invention is to provide the possibility of loading blanks of different diameter and length without readjusting the cells of the store.

This is achieved by the fact that the plates are installed ₅ on the case of the store so that they can be rotated from each other along the store at a distance equal to the shorter length of the workpiece, each pair of oppositely arranged plates forming the cell being connected between 10 by a spring. Plates are made in the form of unbalanced levers.

FIG. 1 shows a general view of the device; in fig. 2 shows section A-A in FIG. one;

The device consists of an auto operator and ¹⁵ magazines for blanks. An auto operator is a mechanical arm 1 with clamping fingers 2 on the grippers 3, which are opposite each other symmetrically with respect to the general geometric ₂₀ axis of the arm 1. The fingers 2 of each gripper can move towards each other in a vertical plane. Arm 1 is located vertically and can move along its vertical axis relative to the carriage 755509

Ki 4, which is movable in turn through the portal 5.

The billet magazine consists of a replaceable cassette 6 mounted on a platform 7, movable in the perpendicular direction of the portal 5. Disk-shaped pre- ₅ billets 8 oriented in the cells formed in the cells formed by the plates 9 and the rods 10. The plates 9 are pivotally attached to springs 12. The distance between the plates along the magazine is equal to the shortest length of the workpiece.

When installing the workpiece 8 in the store, the workpiece squeezes the plate 9 (if it is longer than the distance between the plates) and is installed on the rod 10. Not pressed the plates with their projections prevent the fall of the workpiece.

When loading the machine, the device works as follows.

The platform 7 is moved until the alignment of the axes of the blanks of one row with the axis of the arm 1 of the auto operator and the axis of the machine (not shown). One of the grips of the hand of an auto operator comes up to the extreme blank, and the fingers 2 of the grip clamp the gate.

The hand 1 rises up, the carriage 4 moves horizontally along the portal 5 and transfers the workpiece to the working area of the machine for installation in the cartridge and its processing. The processed billet by hand 1 is transferred to the store and installed on a free space in the store, then a new billet is taken, and the process is repeated.

After processing the entire number of blanks, platform 7 moves to a step, combining the axis of the centers of the next row of blanks with the axis of the machine spindle. In the store you can set the workpiece of different diameter and length. The plates 9 and the rods 10 will hold them in the oriented position. Adjustment of the position of the plates 9 is not required.

The proposed device provides the versatility of the use of cartridges for billet, different in diameter and length without changeover cassettes, which simplifies their use, increases the capacity of the store.

Claims (2)

Claim 1. Device for loading "cutting machine, containing a magazine with orienting cells formed by plates, and an operator, characterized in that, in order to ensure the loading of workpieces of different diameter and length, the plates are installed on the magazine with the possibility of rotation and are located from each other along store at a distance equal to the shorter length of the workpiece, with each pair of opposite plates located forming a cell connected to each other by a spring. 2. Device by π. 1, characterized in that the plates are made in the form of unbalanced levers.,
