Description

The invention relates to mechanical engineering and can be used to load lathes.

The aim of the invention is to increase productivity by reducing the time for readjustment when working with parts of different lengths.

FIG. 1. shows a mechanical arm, general view; in fig. 2 is a section AA in FIG. one..

Rolling pins 2 are fixed in case 1 of the mechanical arm, the axes of which are parallel to the axis of the clamped mechanical arm of the workpiece 3. On the rolling pins 2 the case 4 of the gripper 5 is movably mounted, the clamping levers 7 and the pneumatic cylinder 8, which rod 9 through the wedge 10 interacts with the rollers 11. The clamping levers 7 are connected with the gripping body 5 by the extension springs 12.

The body 4 of the gripper 5 is pivot-tight relative to the body 1 of the mechanical arm by means of a spring 13 of compression.

The microswitch 14 is fixed on the body 1 of the hand with the ability to interact with the body 4 of the grip,

Mechanical works as follows.

AFIG. g

202881

A gripper hand 5 is fed to a drive (not shown) with blanks 3.

Clamping the workpiece 3 occurs in reg 5 through the supply of compressed air

in the piston cavity of the pneumatic cylinder 8. The rod 9 moves the wedge 10, which closes the clamping levers 7.

Then the hand performs functional movements due to the layout of the automated machine and the design of the auto operator.

When approaching the hand to the cartridge 15. The machine tool 3 prepares with its 15 end face in accordance with the tweeter of the surface of its cams. Capture 5 while

stops, and the body 1 of the arm carrying the microswitch 14 continues to move, compressing the spring 13. After passing the specified distance H, the microswitch 14 interacts with the body 4 and sends a signal to the workpiece clamp 3 by the chuck 15, opening the clamping levers 7 and discharging the mechanical hand of the operator.

Regardless of the length of the workpiece 3, its configuration, i.e. from the length of the path that the mechanical arm passes from the accumulator to the insertion of the workpiece 3 into the cartridge 15, the signal is given when the workpiece reaches 3 jaws of the cartridge 15.
