SU514687A1 - Manipulatory Executive Body - Google Patents

Description

The invention relates to a manipulator, in particular, an actuator of the manipulator for capturing products of the type of alitized inserts for compression rings of pistons from the working area and placing them in a chill mold. Known executive bodies of manipulators include a body, a grip, and a ball of rotation of a grip with a drive. However, such a manipulator does not provide high quality stacking of alitized inserts under compression rings in the metal mold, because an insert made of wear-resistant material is better immersed in the aluminum melt bath for better adhesion to the main alloy of the molten plastics and when it is removed from the melt drips are formed which, crystallized in air, increase and distort the diameter of the insert. The purpose of the invention is to improve the quality of manufactured inserts for compression rings. This is achieved by the fact that the executive body is equipped with a shock-pulse mechanism mounted on the housing and kinematically connected with the drive of the rotation of the gripper. The shock-impulse mechanism is made in two ratchet coupling halves, one of which is set movably and kinematically connected with the gripping jaws. In FIG. 1, the image shows the described executive body of the manipulator, general vi /; in FIG. 2, a diagram of the manipulator with the proposed executive body. Manipulator actuator with housing 1 with shock-pulse mechanism 2 mounted on it, gripper with jaws 3 pivotally connected with levers 4 fixed on lower end of rod 5, fitted with return spring 6 and mounted on upper end of rod 7 with a roller S, interacting with the bevel 9 of the rolling pin 10, movable From the drive 11 of the grip (FIG. 2). The hinge of rotation of the grip in the vertical plane is connected to the drive 12 through the crank 13 and the shaft 14 fixed on the body 1 and located inside the arm 15c by a gear 16 rigidly fixed on it, Shock3

The new mechanism 2 has a popumufta wheel 17, a snoring oolumufta 18 with springs 19 and a latch 20, acting through the jaws 3 on the machined ring 21 and also the actuator 22 of the turn of the hand 15,

When the actuator 11 is turned on, the rolling pin 10 through the system of levers moves to the extreme left hulosch and, with its bevel 9, acts through the roller 8 and the guide 7 on the rod 5, moving it down. In this case, the spring 6 is compressed, and the levers 4 are pivotally attached to the end of the rod 5 and act on the gripping jaws 3, moving them apart, and fixing the machined ring 21 on the inner diameter of three (according to the number of jaws). After that, the actuator 12 rotates the gripper in the vertical plane, which acts with a rod on the crank 13, transmitting the rotation to the shaft 90, and turns the body 1, When the body 1 rotates the coupling half 17, wrapped around the gear 16 fixed on the arm 15 , the ratchet coupling half 18 is rotated. In this case, the teeth of the ratchet coupling half rattling, creating a shock-pulse loading, which results in constant shaking of the processing device fixed in the jaws 3 (cola 21).

The semi-coupling 18, interacting with the wheel of the half-coupling 17, moves only in a pneumatic manner and overcomes the force of the springs 19. The coupling half-18 is held by a clamp 20 from rotation, which is in the locked position in this NJOMOHT. As soon as the gripper of the manipulator takes up the vertical (working) position, the actuator 22 turns the arms of the manipulator and the sponge is set to a predetermined position (above the metal mold), then the actuator 23 moves the vertical displacement of the manipulator and

ring 21 is lowered (in a chill mold). The next time the drive 11 is turned on, the rolling pin O moves to the extreme right position, whereby its bevel 9 comes off the roller 8, freeing the spring 6, which with its own force presses the shanks 5 to the extreme upper position and through the levers 4 reduces the sponge 3, freeing the ring 21. After the vertical movement actuator switches and the gripper returns to its original position (to the bath). In this case, the latch 2O disengages, the wheel of the half-coupling 17 and the ratchet coupling half 18 are locked with the back side of the teeth and work as one piece, so as to run around the pinion 16,

As soon as the gripper of the manipulator has taken a horizontal position and the hand 15 has been turned to its original position, the drive 12 of the gripper rotation and the actuator 22 of the turn of the handle 15 are turned off and the operation cycle of the manipulator is repeated.
