Description

one

The invention relates to the field of machining of metals, namely, to auto operators for centering automatic lathes and automatic lines for machining shaft-like parts.

Known auto operators with drive links for loading and unloading lathes, the gripper axes of which are parallel to the axis of the centers of the machine.

The described autoradiator is different from the known ones in that the grippers are fixed on the axles movably mounted on the drive links x. The axes of the grippers that carry out the loading are equipped with a bracket that interacts with the stop mounted on the machine ninoli, and on the fixed part of the auto-operator are two shoulders levers that interact with the stops on the drive links.

The invention is shown in the drawings, where in FIG. 1 - auto operator in the position corresponding to the beginning of the unloading of the machine, view from the end of the machine (from the tailstock); in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 is a view of B in FIG. 1 (the unloading arm of an auto operator is depicted in the lowered position, corresponding to the moment when the tailstock of the machine’s tailstock begins to move).

Hydraulic cylinders (or pneumatic cylinders) of loading 2 and unloading 3 hands of the operator are installed on the carriage 1 of the auto-operator. On the stock of the hydraulic cylinder of the loading arm 2, a clip 4 is installed, which is an irrivodny link of this hand. (Zkalka 5 is non-reversible, turns back the rotation of the bracket 4 relative to the axis of the rod. In the bracket 4 there are two axes 6, which move freely relative to the bracket along

of their axes and fastened with plaque 7. On the x-6 axes, the grippers 8 are also freely mounted, which have a gear (in pairs) with each other. The movement of the grippers 8 along the axes b is prevented by the block 9, rigidly

fortified on axle x 6 and placed inside the grippers 8 having U-shaped shanks. The drive of the grippers can be either long-spring (as shown in Fig. 1), or hydraulic, pneumatic, etc.

On the hydraulic rod of the discharge arm 3, similar brackets 10 (drive link) are installed, axles 11 with a bar 12, grips 13 with pads 14. On the machine 15, the autoradiator can be set in various ways. FIG. Figure 1 shows an embodiment where the auto operator carriage 1 is mounted on the beam 16 and is moved along it with the help of rollers 17. The auto operator works as follows.

When giving the command to unload the machine, the hydraulic cylinder rod of the unloading arm 3 moves downwards. At the end of the stroke of the rod grips 13 capture the item 18 (see Fig. 4) installed in the cartridge 19 flock and nodzhatuyu center 20 Ninoli 21 of the headstock 22 of the machine. After that, the ninola 21 of the machine’s tailstock is retracted to the right. In this case, the center 20 is first brought out of the center hole of the part 18 (at its end), and then the reset 24, connected to the axes 11 of the unloading arm, moves the axes II, and with them the clamps 13 and the part 18 to the right, withdrawing the part from the cartridge 19 Then, the hydraulic cylinder rod of the discharge arm moves upwards. At the end of the upward stroke, the stop 25 of the bracket 10 acts on the lever 26, whose axis 27 is mounted on the fixed part of the arm, and turns it. As a result of the rotation, the lever 26 with its second shoulder acts on the support 28 fixed on the shoe 14 and returns the axles 11 and the grippers 13 to the extreme left (initial) position.

Further, the stock cylinder of the loading arm moves downward, moving the workpiece 29 to the axis of the machine centers. Then the quill 21 moves to the left, moving the workpiece 29 (along with the grippers 8 and the axle 6). After entering the workpiece in the chuck hand hydraulic cylinder rod

moves up. At the end of its stroke, the stop 30 acts on the lever 31, which with the help of the stop 32 on the block 9 returns the grippers 8 of the loading arm to the extreme right (initial)

position.

Thus, the input of the workpiece into the cartridge and the output of the machined part from the cartridge are carried out without the use of an additional drive, and these operations are combined in time with other operations on the machine.
