DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to equipment suitable for blasting products such as cylinder blocks of automobile engines.

[0002]

2. Description of the Related Art Conventionally, as this kind of shot blasting equipment, as disclosed in Japanese Patent Publication No. 58-27065, it is necessary to hold a product in a cantilevered state and rotate it outside the polishing chamber. There is a configuration in which a plurality of possible clamping devices are disposed so as to be movable along the cleaning chamber, and the product is passed through the cleaning chamber while rotating. However, in the shot blasting facility configured as described above, the structure of the clamp device and the moving device for moving the clamp device is very complicated, and the area for installing the entire facility needs to be very large. was there.

[0003] Therefore, as disclosed in Japanese Patent Publication No. 63-15106, a two-set product clamping device having two pairs of claws capable of holding and rotating a product from the left and right sides is provided in a cleaning chamber. Shot blasting equipment has been proposed that can be blasted by arranging it in a vertical plane so that products can be blasted.However, this equipment cannot grip various products of different sizes, There were problems such as lack of sex. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a shot blasting facility capable of accommodating products of various sizes in addition to a small installation area of the facility. is there.

[0004]

Means for Solving the Problems In order to achieve the above object, a shot blasting apparatus of the present invention is an apparatus which can perform blasting while rotating a product in a vertical plane in a cleaning room, A cabinet that constitutes a cleaning room, a rotating plate that is intermittently rotatable in a vertical plane with respect to the cabinet, and a product that is mounted on the rotating plate at substantially equal intervals along the periphery. A plurality of clamping devices for gripping and rotating in a vertical plane in the cabinet, wherein the clamping device includes a rotating body rotatably arranged in a vertical plane, and two rotating bodies mounted on the rotating body. A pair of rotatable arms mounted to face each other in a cantilevered state at a required interval via a support shaft, a holding member mounted to a tip of the arm to hold a product,
A pair of links each having one end fixed to the support shaft; a connecting rod having one end connected to the other end of the pair of links; and a reciprocating longitudinally moving the connecting rod mounted on the rotating body. And an actuator.

[0005]

With the above construction, the gripping member of the clamp device is opened and a product is carried between the gripping members by an appropriate means. Next, the gripping member is closed to grip the product, and then, while the product is rotated in the vertical plane by the clamp device, these clamp devices are intermittently revolved in the vertical plane via the rotating plate. Thus, the product is blasted by receiving the abrasive material being projected.

1 to 3 show an embodiment of the present invention.
This will be described in detail based on FIG. As shown in FIG. 1 which is a front view, a rotating shaft 3 penetrating left and right through a cabinet 2 near the center of a cabinet 2 comprising a plurality of blasting material projecting devices 1 and constituting a blasting room is provided with bearings 4 and 4. The output shaft of a motor 7 with a reduction gear mounted on the support 5 is connected to the left end of the rotating shaft 3 via a shaft joint (not shown). . A central portion of a disc-shaped rotating plate 8 is fixed to a position on the right outside surface of the cabinet 2 on the rotating shaft 3, and a left side surface of the rotating plate 8 and a portion inside the cabinet 2 on the rotating shaft 3 are connected to each other. Is mounted with a plurality of partition plates 9 extending radially about the rotation shaft 3 so that a plurality of rooms can be defined.

[0007] As shown in FIG. 2, partition members 2 a, 2 b, and 2 c constituting a cleaning chamber with the partition plate 9 are appropriately mounted on the inner surface of the cabinet 2. Further, a plurality of clamping devices 10 are mounted on the rotating plate 8 at substantially equal intervals along the periphery of the rotating plate 8 so that the plurality of clamping devices 10 are partitioned by the partition plate 9. Made up of As shown in FIG. 2, an entrance and an exit are provided on the left side wall of the cabinet 2 so that a product placing member 11 on which a product is placed can enter and exit, and a rubber curtain type sealing mechanism (not shown) is provided. (Not shown)
Are provided respectively.

As shown in FIG. 3, the clamp device 10 is provided on a support member 15 fixed to the rotating plate 8 via a bearing 16 so as to be rotatable in a vertical plane. The rotating member 18 with the support member 1
5, a motor 19 with a speed reducer installed on
A sprocket 21 fitted to the output shaft of the motor 1 and connected to the sprocket 17 via an endless roller chain 20;
8, a cylindrical connecting member 22 mounted concentrically on the left outer surface, a rotating body 23 mounted on the left end of the connecting member 22 and rotatable in a vertical plane, and two rotating bodies 23 A pair of leftwardly extending arms 25 which are mounted in a cantilevered state and are rotatable via a support shaft 24, and a stopper member pivotally supported by the left end of the arm 25 and capable of moving the product by a predetermined distance. Holding members 27 and 28 having 26
And a pair of detent members 29, one end of which is fixed to the two support shafts 24, one end of which is fixed to the lower holding member 28 and the other end of which is rotatably supported by the rotating body 23. A link 30, a cylinder 31 as an actuator mounted on the rotating body 18, and a connecting rod 32 having one end connected to the link 30 with a pin and the other end connected to the tip of a piston rod of the cylinder 31. I have. As a result, the gripping members 27 and 28 are opened and closed via the arm 25 by the contraction operation of the cylinder 31.

In the above-described structure, the cylinder 31 of the upper left clamping device 10 in FIG. 2 is extended to open the gripping members 27 and 28, and the product is inserted between the gripping members 27 and 28. The product W is carried in by the mounting member 11. Next, the cylinder 31 is contracted to close the gripping members 27 and 28, the product is gripped by the gripping members 27 and 28, and then the product setting member 11 is retracted. Next, the motor 19 of the clamp device 10 is rotationally driven to rotate the product W in a vertical plane. In this state, the motor 7 is driven to rotate the rotary plate 8 via the rotary shaft 3, and the clamp device 10 is rotated intermittently in the vertical plane via the rotary plate 8. As a result, the product W is subjected to the blast processing by receiving the abrasive material projected from the abrasive material projection device 1.

When the product W is moved to the lower left position in FIG. 2 by the clamp device 10, the product placing member 11 is moved into a position below the clamp device 10, and then the cylinder 31 is extended. Gripping member 2
7 and 28 are opened, the blasted product is placed on the product placing member 11 and carried out of the apparatus, and one cycle is completed.
