Description

[Detailed Description of the Invention] The present invention relates to a workpiece feeding and setting device that accurately feeds and sets a plate-shaped workpiece into a hole of a set object with good concentricity.

Conventionally, in order to set and weld a workpiece into each hole of a set object in which a plurality of holes are drilled at a constant pitch, the first hole and the work supply setting means are manually positioned concentrically, After that, it is enough to send the object to be set at a predetermined pitch. In reality, the pitch of the holes is not constant, making it impossible to accurately feed and set the workpiece into the hole. This is particularly noticeable in the case of holes in castings. .

This is because holes in castings are often made with cores, which causes considerable misalignment.

For this reason, in the past, the operator had to set the workpiece in the hole each time, resulting in a problem of poor efficiency.

The present invention has been developed in view of the above circumstances, and its purpose is to provide a workpiece supply and setting device that can accurately supply and set a workpiece to a hole in a set object with good concentricity.

Next, the operation will be explained.

The piston rod 56 is contracted and the finger 58 and guide 59 are moved rightward in the figure to support one work A of the work stocker 55 at a predetermined position of the finger 58.

On the other hand, the piston rod 49 of the work setting cylinder 4T is retracted to draw the electromagnet 50 into the positioning member 48 and stored therein, and in this state, the piston rod 46 of the lifting cylinder 45 is retracted.
is extended to fit the downwardly tapered portion 48a of the positioning member 48 into the hole 62.

(See FIG. 5) At this time, if the center of the positioning member 48 and the center of the hole 62 are not aligned, a moving force in the X-Y direction will be applied to the positioning member 48 by the downward tapered portion 48a, and 44 is the left and right, front and rear mounting rods 8゜18.24,2
5th bearing 6, 7, 16, 17° 26.27, 35.36
move in the X-Y direction between the two.

As a result, the center of the positioning member 48 coincides with the center of the hole 62.

In this state, the clamp cylinders 11, 21, 31, and 40 of each clamp mechanism IQ, 2G, and 30°39 are extended to separate the movable clamp pieces 12, 22, and 32°41 and the fixed clamp piece 1.
3, 23, 33.42 and each mounting rod 8.18.24.2
5 to the bracket 9°19.34.43.

As a result, the mounting plate 44 is moved and fixed in the X-Y direction.

Next, the piston rod 46 of the lifting cylinder 45 is contracted, the positioning member 48 is moved upward, and the piston rod 56 of the workpiece supply cylinder 54 is moved (Et'1%) so that the finger 58 and the guide 59 are Move to the left.

As a result, the guide groove 60 of the guide 59 is aligned with the positioning member 48.
Since the finger 58 is fitted with the electromagnet 50, the positional deviation of the finger 58 with respect to the electromagnet 50 is corrected and the finger 58 is maintained at a predetermined position with respect to the electromagnet 50.

That is, the guide groove 60 of the guide 59 is aligned with the positioning member 48.
If there is any misalignment when fitting the mounting base 53 to the base 51.
On the other hand, since the turning guide groove 60 reliably fits tightly into the positioning member 48, the finger 58 and the electromagnet 50 are maintained in a predetermined positional relationship.

In this state, the piston rod 49 is extended and at the same time the electromagnet 50 is excited to attract and support the workpiece A supported by the fingers 58.

After that, the fingers 58 and guides 59 are removed in the same manner as described above.
When the movement is completed, the piston rod 49 of the workpiece setting cylinder 41 is extended and the workpiece A is placed around the hole 62 and brought into contact.The electromagnet 50 is demagnetized and the piston rod 49 is moved. Shrink it and move it upwards.

As a result, the work A is accurately supplied and set around the hole 62.

After completing the set, each clamp mechanism 10, 20° 30.3
Unclamp 9 and return to origin cylinders 64, 65, 6
6. Activate 67 to return the positioning member to its original position.

Thereafter, the set object 61 is conveyed and positioned at a predetermined pitch by the conveying means 63, and the hole portion 61 is moved by the same operation as described above.
Set the workpiece to 2.

As described above, the work A can be accurately and concentrically supplied and set in each hole 62 of the set object 61 in which a plurality of holes 62 are bored at a predetermined pitch.

Since the present invention is configured as described above, the work A can be accurately supplied and set in the hole 62 of the object 61 with good concentricity.
