Abstract

PURPOSE: To treat many kinds of castings with the same robot and to economically manufacture a grip part used to together with a feeder head by arranging the grip part forming the outer shape to a prescribed shape and the same shape as the grip parts of the other kinds of castings. CONSTITUTION: The grip part 1 has the cylindrical shape having a prescribed diameter projected from a part of the feeder head W1 in the casting W and the same shape as the grip parts of the other kinds of castings and can be treated with the same robot hand H. This grip part 1 serve also as a part of the feeder head arranged to reinforce molten metal to solidified shrinkage of the molten metal. The casting W arranging the grip part 1 can be shifted by gripping with the chuck C of the robot hand H and the chuck C is formed to linkage chuck mechanism easily centering with three claw mechanism. By using such mechanism, since the shape of the grip part 1 is the same even if the kind of the casting is different, the change of the robot hand H is unnecessary, and the grip part 1 serve also as the feeder head can economically be produced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case where a robot hand removes a casting from a casting mold and moves the casting to another place at the time of casting production, or when the robot hand moves the casting to a predetermined place in the next manufacturing process. The present invention relates to a suitable casting.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view showing a state in which a casting W'is being gripped and moved by a robot hand H. That is, the robot hand H has a raised portion 1'formed by a gate, a feeder provided on the casting W'or a product portion.
Is held by a chuck C having a three-claw structure provided at the tip of the robot hand H to move the casting W ′.

[0003]

However, in the above-mentioned conventional casting, since the size and shape of the raised portion to be gripped by the robot hand are different depending on the shape and type of casting, each casting shape and type are different. There is a drawback that the robot hand has to be replaced with one that matches the raised portion, and many robot hands must be prepared, resulting in high cost.

Therefore, the present invention has been made to solve the above-mentioned drawbacks, and an object thereof is to provide a casting which does not require replacement of the robot hand.

[0005]

In order to achieve the above-mentioned object, the present invention is provided in another type of casting having an outer shape of a convex shape having a predetermined shape and being held by the same robot hand. It is characterized in that the same grip portion as the grip portion protruding outward is provided. Further, it is characterized in that the grip portion also serves as a feeder.

[0006]

In the above structure, the casting moves while the gripping portion is gripped by the robot hand.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view when the casting W is used as an intake manifold, and FIG. 2 is a part of a side view of FIG. 1 viewed from the direction a.

In the figure, reference numeral 1 is a gripping portion, which has a cylindrical shape with a predetermined diameter provided so as to project outward from a part of the feeder W1 of the casting W. That is, this grip 1
Has an outer shape of a convex shape having a predetermined shape, and the shape of the grip portion 1 is the same as that of another type of casting (not shown) moved by the same robot hand H. Is formed in.

When the casting W is cast, the gripping portion 1 also serves as a part of a so-called feeder, which is attached to the casting to reinforce the molten metal against solidification shrinkage of the poured molten metal. There is.

The casting W provided with the grip 1 is
As shown in FIG. 2, the chuck C of the robot hand H is
It can be grasped and moved with. The chuck C has a three-claw structure and is configured as an interlocking chuck mechanism that allows easy centering. Moreover, this gripping portion 1 has the feature that the robot hand H does not need to be replaced according to the type of casting, unlike the conventional case, because the shape of the gripping portion 1 is the same even if the type of casting W is different. are doing.

Further, since the gripping portion 1 is also used as the feeder W1, the shape of the feeder is the same as that of the other castings W, and it is not necessary to specially make it, which is economical. Can be made into

In the above-described embodiment, the shape of the gripping portion 1 is cylindrical, but the chuck C of the robot hand H has two shapes.
In the case of holding by one piece, the shape can be a prismatic shape or a plate shape. Furthermore, when the feeder is provided with another feeder, for example, another feeder W2 is provided at the bottom of FIG.
, The gripping portion 1a may be provided at the portion of the feeder W2, or in some cases, at the gate W3.

Further, in the above-described embodiment shown in FIGS. 1 and 2, the gripping portion 1 is projected upward as shown in FIG. 2, but as shown in FIG.
In some cases, as shown in FIG. 3 (b), an upward grip portion 1 c with a shifted position may be used.

[0014]

Since the casting according to the present invention is a protrusion having an outer shape of a predetermined shape and provided with a gripping portion projecting outward, which is gripped by the same robot hand, the same robot hand is provided. Can be used to move different types of castings. Further, when the grip portion is also used as the feeder, the grip portion can be economically manufactured.
