Description

A loading device is known, for example, to an automatic lathe for machining the outer surface of cup-shaped blanks supplied by a rotary mechanical arm with one gripper that carries the part from the mecha-nism to the position of the machine spindle. The workpiece is pushed into the machine spindle by a pusher that has been pushed out as an axially movable rod. The machined part is dropped into the discharge chute by a second movable pusher installed inside the machine spydel.

The proposed loading device is characterized in that it has an axially movable pusher with two cheeks, one of which is on the loading side of the spindle, and the other on the opposite side and acts on the movable bushing pushing the part into the grip, simultaneously pushing it out of the spindle finished product. The cheek, located on the side beyond the shpinindles, acts simultaneously on the part, loading the spindle, and on the finished product, releasing it in the discharge area. This reduces the cycle time for loading and unloading parts.

The drawing shows a general view of the device, its plan view and section of the drive-body of the boot arm.

The device contains a koryuus, /, which is fixed on the machine, the IB of which holds the loading arm 2. The loading arm is a single sector with two grippers 3 and 4 of the spring type, which are located at a distance of each other that is shortened to each other. blank from loading tray 5 to chuck b.

The loading arm makes a turn around its axis at a predetermined angle during the working stroke with the help of pneumatic | Tsilin, core 7 through a rack-toothed pair 8-9. Gear rack and pinion lars mounted on the same shaft with the boot arm. To return the boot arm. In its original position is the spring -10.

Workpieces from the loading tray 5 to the top: grip 3 of the loading arm (supplied by the movable sleeve 11 at 1PARAMENT of a single U-shaped pusher 12, which has the constructive shape of the loaded parts, driven by a pneumatic cylinder 13. The same U-shaped pusher 12 sets the workpiece zalimnoy cartridge 6 and pushes the machined parts in the discharge tray 14 in time; its reverse.

The boot device works as follows.

it is installed so that its upper dinner frame is located opposite the loading tray 5 a 1N Ж1Ний - against the chuck 6. At the same time, the workpiece is in the loading slot 5, and the workpiece is being processed.

At the end of the processing and the chuck's rabbi; P-ab, the DIFFERENT pusher, / 2 doubles forward from the action of the pneumatic shield of the cylinder 13. At the same time, pushing out the filling from the loading tray 6 to the top (gripping the loading hand three HELP sleeve L, it simultaneously removes the machined part with zazhrgmnopatro 6 and pushes it into the bottom spring grip.

(After that, the pneumatic slit 7 through a rack-and-pinion pair 8-9 (turns the loading arm 1 to a given angle. The upper grip with the workpiece is set against the clamping cartridge 6, and the lower part with the processed Part is against the discharge tray 14. Then the movement The P-arm pusher / 2 returns to its original position, and at the same time with this movement it sets the upper grip 113 of the upper gripper in the clamping patro, n 6, and pushes the machined part out of the lower gripper of the loading hand into the discharge chute 14. Then t clamping the workpiece in the chuck and its processing. Reverse movement to the original lozhe "is not 13 a1 load; on the hand it performs under the action of spring 10 to return during the machining process of the part.

At the end of the processing process, the unloading-unloading cycle is repeated in the same order.

P d. M et and about b.

Loading device for metal cutting machine tools, made in the form of a double gripping rotary mechanical arm, transferring a part from the feeding mechanism into the machine spindle and from the spindle to the unloading zone, which is different there With the aim of unloading it during the loading and unloading cycle parts, in it there is an axially movable pusher with two cheeks, one of which is on the loading side of the spindle, the other with the opposite, and a movable sleeve that pushes the part into the grip, simultaneously with the hinge vanie.m spindle of the finished product, and the cheek located on the side of the spindle load, acts simultaneously on the workpiece by charging a spindle on .gotovoe product, releasing it in the unloading zone.
