BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail with reference to FIGS. 1 to 6, taking a cylinder block as an example. 1 shows an overall plan view, and FIGS. 2 to 3 show FIG.
2 is a view taken in the direction of arrows B-B in FIG. 4 to 6 are views taken in the direction of arrows AA in FIG. 1 (rotated 90 degrees), FIG. 4 shows a material loading state, FIG. 5 shows a material positioning state, and FIG. 6 shows a material unloading state.

Frame for material loading and unloading carts erected in a gate shape
A material loading station 2, a material processing station 3, and a material unloading station 4 are provided below the frame 1 at appropriate intervals, and the material loading / unloading truck frame 1 has a ceiling portion. Is provided with a trolley rail 5.

A dolly 7 is mounted on the dolly rail 5 so that it can be horizontally moved between the stations 2, 3 and 4 by the operation of a servo motor 6. A hook-shaped lifting arm 9 that is lifted up and down by an electric cylinder 8 as a lifting cylinder is hung on 7. The key-shaped lifter
A fork body 10 having a large number of claws arranged at intervals is connected to the lower portion of the frame 9 in a horizontal state.

The material carrying-in station 2 carries in a cylinder block W as a casting material for carrying in a cylinder block W.
However, the material unloading station 4 is provided with unloading means 4A for unloading the cylinder block W, respectively.
Further, the material processing station 3 is provided with the following material positioning device 3A and processing robot 3B.

Next, the structure of the material positioning device 3A will be described. A work table 14 having a lower portion connected to a rotary shaft 13 rotatably supported on the base 11 via a bearing 12 is installed above the base 11, and the work table 14 is installed. A stopper body 15 is attached to one end of the bull 14. A tilt cylinder 16 for tilting the work table 14 is installed on the base 11, and the tip of the piston rod of the tilt cylinder 16 is connected to an arm (not shown) fixed to the rotary shaft 13. Has been done. Further, on the upper surface of the work table 14, a free roller conveyor 1 is provided.
Nos. 7 and 17 are arranged at intervals so that the claws of the fork body 10 can be inserted.

A pair of clamp cylinders 18 and 18A for holding the cylinder block W are provided at both outer positions of the cylinder block W at the tilting end of the work table 14, and the clamps are provided. Cylinder 1
Reference numerals 8 and 18A denote the base 1 through a frame (not shown).
It is attached to 1. Further, in the pair of clamp cylinders 18 and 18A, the driving pressure of the clamp cylinder 18 which is initially extended to the stroke end is set to be higher than the driving pressure of the clamp cylinder 18A which is extended and operated later.

Next, the processing robot 3B will be described.
Work table 14 in the material processing station 3
A machining robot 3B for machining the cylinder block W is arranged at an outer position on the tilting side of the machining robot 3B. The machining robot 3B is provided with a deburring tool (not shown) and a cleaning air blower.
Equipped with nozzles.

Since the processing robot 3B processes each cylinder block W having a different size and shape for each vehicle type, teaching is performed in advance for each vehicle type. Therefore, it is not necessary to provide a common reference plane for each vehicle type.

The operation of the thus constructed device will be described. When the cylinder block W is loaded onto the loading means 2A of the material loading station 2, the servo motor 6 and the electric cylinder 8 are actuated to move the fork body 10 suspended from the carriage 7. The cylinder block W is scooped up (left end in FIG. 2) and moved to the material processing station 3 and lowered at the material processing station 3 to move the free block.
It is transferred onto the roller conveyors 17, 17 (see FIGS. 2 and 4).

Next, the tilting cylinder 16 is contracted and retracted to tilt the work table 14 to the tilting end about the rotary shaft 13 as shown in FIG. 5, and the cylinder block W is freed.
The roller conveyors 17 and 17 are lowered until they come into contact with the stopper body 15 to perform vertical positioning.

In this state, the clamp cylinder 18 is extended to the stroke end, and then the other clamp cylinder 18A is extended. As a result, the cylinder block W is clamped and positioned in the left-right direction. At this time, as described above, the driving pressure of the clamp cylinder 18 that is initially extended to the stroke end is set to be higher than the driving pressure of the clamp cylinder 18A that is extended afterwards, and the clamp cylinder 18 is It will not be pushed back.

In this way, the cylinder block W in the inclined state, which is vertically and horizontally positioned, is subjected to deburring processing, sand removal cleaning, etc. by the processing robot 3B. At this time, since the cylinder block W is processed and cleaned in an inclined state, casting burr, sand and the like can be easily discharged.

When the processing of the cylinder block W is completed in this manner, the clamp cylinders 18 and 18A are contracted and then the tilting cylinder 16 is expanded. After that, by operating the servo motor 6 and the electric cylinder 8, the fork body 10 is inserted below the cylinder block W, and the cylinder block W is pulled up and moved to the material carrying-out station 4. It is lowered at the carry-out station 4 and transferred to the carry-out means 4A (see FIG. 3).
And FIG. 6). Then, the unloading means 4A sends the cylinder block W to the next step.

In the embodiment of the present invention, the cylinder block is described as an example of the casting material, but the present invention is not limited to this, and the casting material may be a cylinder head or the like.

[0022]

As is apparent from the above description, the present invention provides a work table having a free-roller conveyor for mounting a casting material on its upper surface and a stopper body at one end. Since it is tiltably supported so as to be on the lower end side, and a pair of clamp cylinders for sandwiching the casting material are arranged at both outer positions of the casting material at the tilting end of the work table. There are various effects such that the casting material having different sizes and shapes depending on the vehicle type can be easily and easily positioned.
