(Prior art) In general, in processing equipment, surface treatment is carried out using a projector within a machine frame.The projector is attached to a holding shaft movably provided in the machine frame, and the projector is used to carry out shots, grids, etc. Metal particles or non-metal particles such as alundum, carborundum, and nylon are supplied together with compressed air and sprayed onto the workpiece surface from the nozzle end to perform surface treatments such as plasting and peening. For example, when treating the outer surfaces of structures and various mechanical parts, a fixed nozzle type projector is sufficient, whereas when treating the inner surfaces of pipes and containers such as oxygen cylinders, is inefficient with a fixed nozzle projector. Therefore, in such cases, it is necessary to replace the projector with a rotating nozzle type projector that is equipped with a rotatable oblique projection nozzle that has a curved path formed on the tip side that allows the projecting material to be projected in a diagonal direction with respect to the axis of the nozzle body. There is. In addition, if the projector malfunctions or the nozzle part wears out, it must be replaced immediately, but this replacement work is extremely inefficient as it has to be done inside the machine frame in a poor working environment. However, there are problems such as attachment and detachment of bolts, etc., which is troublesome as crushed particles may get caught.

Next, when the holding shaft (13) is raised by the lifting table (3), the projector (29) is pulled out from the chuck (18) of the bracket (17) and transferred to the holding shaft (13). However, as mentioned above, the concave groove (44
) and the reference shirt) (26b), the engagement protrusion (45), and the guide groove (27b), the projector (
29) is always maintained in its normal mounting state without causing any positional deviation in the left-right direction with respect to the holding shaft (13). In this state, the cart (53) is sent into the machine frame (1), the object to be processed (-) enters a predetermined position, and the projector (29) is directed diagonally onto the inner surface of the object to be processed (-). The projection nozzle (37) is faced, and the inner surface is treated by moving the oblique projection nozzle (37) vertically and horizontally while rotating it by the operation of the motor (34). When processing the outer surface of the object to be processed (-), move the holding shaft (13) to the lifting table (3) and the traversing table (9).
The locking body (23) is moved by a method such as the locking member (23), so that the locking groove (43) of the free side locking portion (42) of the projection a (29) is brought to the forward position in the chuck (18) of the bracket (17).
After being positioned upward, the holding shaft (13) is lowered and the projector (29) is fixed to the chuck (18) and transferred and held by the reverse operation. Next, the holding shaft (13)
The cylinder (21b) of the chuck (18b) is actuated to move the locking body (23b) forward to release the engagement with the engagement part (42), and then the holding shaft (13) is raised to release the engagement part (42). (
42), then remove the holding shaft (13) from 180@
Turn it over and attach the chuck (18b) to the bracket (17
The above-mentioned similar engagement part (
42). After that, the holding shaft (1
3) to lower the locking body (23b) of the chuck (18b).
) is inserted into the engagement groove (43) of the engagement part (42) and fixed in place, and the engagement part on the other side is released from the bracket (17a) by the operation of the chuck (18a), thereby releasing the projector. (46) is transferred to the holding shaft (13) and fixed. Subsequently, projection 419 (4
6) is moved to a predetermined position, and a straight-shaped projection path (
The object to be processed (-
). Further, when replacing the projector due to repair or the like, the same operation may be performed. In addition, when surface-treating the side surface of the object to be treated or a cavity formed in the side surface, the holding shaft (13) is lowered to a predetermined position and the rotating part (14) is operated to move the projector ( 29), 46) may be set horizontally to inject the blasting material, and the brackets (17), (17a)
) are placed in opposing positions, but they may be provided on the same side wall, and the number of them may be determined according to the number of projectors required. Furthermore, if necessary, a sensor such as a proximity switch can be installed on the chuck (18), etc. to confirm the chucking of the projector, and for this purpose, a proximity switch is provided at an appropriate location on the inner wall of the casing (19), etc. However, a corresponding actuating piece may be fixed to a portion that moves forward and backward by the operation of the cylinder (21), for example, to the side surface of the holder (24).

(Effects of the Invention) As is clear from the above description, according to the present invention, the projector can be operated when necessary by being held by a chuck for holding the projector provided on a holding shaft that is movable within the machine frame. It is held in a chuck for the stock of the projector in the frame and can be automatically and quickly replaced with another projector, and the projector can be mounted and removed by an operator under unfavorable working conditions as in the past. is no longer necessary, greatly improving productivity.
