Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rail-shaped nozzle used to clean a screw hole or the like drilled in the bottom of an object to be cleaned that is transported into a cleaning chamber of a cleaning machine.

Conventionally, when cleaning screw holes etc. drilled in the bottom of the object to be cleaned, a pair of rails provided in the washing machine as the object conveyance path are connected to each other in the cleaning chamber. disposing a pair of rail-shaped nozzles each forming a fluid path and a high-pressure fluid ejection path that opens upward and communicates with the fluid path;
An object to be cleaned is placed on the rail-shaped nozzle, and the object is cleaned by jetting high-pressure fluid into a screw hole or the like drilled in the bottom of the object.

However, the rail-shaped nozzle has through holes drilled from both ends in the longitudinal direction with a drill or the like,
Since the rail-shaped nozzle is quite long, it is manufactured by plugging the openings formed at both ends to form a fluid path, and then drilling a jetting path in the upper surface that communicates with the fluid path. It is difficult to process the fluid path.
Burrs are generated at the intersection of the fluid path and the ejection path, and it is difficult to remove the burrs. If used without removing burrs, the ejection passage will frequently become clogged.
Difficult to clean. There are other problems.

The object of the present invention is to provide a rail-shaped nozzle with an extremely simple structure that can solve these problems. Therefore, in the present invention, a fluid chamber is formed by a nozzle body having a groove opened in one direction and a plate member attached to the nozzle body so as to cover the groove. The nozzle main body and the plate member are removably fixed to each other, with a jet passage communicating with the fluid chamber and opening toward the cleaning section of the object to be cleaned.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. In Fig. 1, 1 is a cleaning chamber provided in a washing machine, and 2 is a cylinder block of an automobile engine transported into this cleaning chamber 1. This is the object to be cleaned. The bottom surface of the object to be cleaned 2 has a screw hole 3,
3,... are drilled. 4, 4, . . . are surface plates arranged at appropriate positions in the washing chamber 1 and indicating the reference plane of the washing machine.

Brackets 6, 6, . . . for fixedly supporting a pair of rail-shaped nozzles 5, 5, . The washing machine is also provided with a pair of rails (not shown) for transporting the object 2 to be washed into the washing chamber 1. A pair of rail-shaped nozzles 5, 5,...
is connected to the pair of rails described above, and is provided in the cleaning chamber 1 so as to form a series of conveyance paths for objects to be cleaned.

As shown in FIG. 2, the rail-shaped nozzle 5 is composed of a rail-shaped nozzle main body 7 and a bottom plate 8, which is a plate member, and the bottom plate 8 is fixed onto the brackets 6, 6, . . . with bolts (not shown). has been done.
The rail-shaped nozzle body 7 is provided with a groove 9 (see FIGS. 2 to 4) that is open in one direction (opening downward in the embodiment) in the longitudinal direction. This rail-shaped nozzle body 7 is detachably fixed to the bottom plate 8 by bolts (not shown). This forms the fluid chamber 10 (see FIGS. 2 to 4).

Notches 11, 11, ... are formed at appropriate locations on the upper surface of the rail-shaped nozzle body 7, and the notches 1
1, 11, . . . have jetting passages 12, 12, .
3. It is formed towards... Spout passage 12,1
2, ... are connected to the fluid chamber 1 through tapered parts (fluid inlet parts) 13, 13, ... that expand toward the fluid chamber 10.
It communicates with 0. Note that FIG. 3 shows the jetting passage 12 for cleaning the screw hole 3 located directly above the rail-shaped nozzle 5, and FIG. A spout channel 12 for cleaning the holes 3 is shown. others,
Reference numeral 14 denotes a fluid supply port that serves as an inlet for high-pressure fluid supplied to the fluid chamber 10, and the fluid supply port 14 is connected in communication with a fluid source (not shown).

Next, to explain the operation of the rail-shaped nozzle configured in this way, first, the object to be cleaned 2 slides on a rail (not shown) provided in the washing machine by a mechanical drive means (not shown). After that, it is transported to a position above a pair of rail-shaped nozzles 5, 5, . . . provided in the cleaning chamber 1. When the object 2 to be cleaned is positioned above the rail-shaped nozzles 5, 5,... at a predetermined set position where it can be cleaned, high-pressure fluid is supplied from a fluid source (not shown) to the fluid chamber 10 of the rail-shaped nozzles 5, 5,... Supplied. The high-pressure fluid supplied to the fluid chamber 10 is directed from the fluid chamber 10 through the tapered part 13 to the respective screw holes 3, 3, etc. drilled in the bottom surface of the object to be cleaned 2 from the jetting passages 12, 12, . As a result, the screw holes 3, 3, . . . , etc. are cleaned. At that time, the rail-shaped nozzles 5, 5,
Fluid and dirt such as chips spouted toward the screw holes 3, 3, etc. located directly above the rail-shaped nozzles 5, 5, ... fall into the cutouts 11, 11, ... of the rail-shaped nozzles 5, 5, ... and are discharged. On the other hand, the rail-shaped nozzles 5, 5,...
After cleaning, the fluid and dirt such as chips that are ejected toward the screw holes 3, 3, etc. located diagonally upward are dropped and discharged. When the predetermined cleaning is completed in this manner, the object to be cleaned 2 is transported to the next step.

Note that the present invention is not limited to the above-mentioned embodiments, and the object to be cleaned 2 may be transported to the cleaning chamber 1 by other means of conveying the object to be cleaned 2, such as a lift-and-carrier system. It may also be transported. In addition, rail-shaped nozzles 5, 5,
. . . Positioning pins may be provided on the upper surface to ensure positioning of the object 2 to be cleaned. Furthermore, when cleaning the object 2 to be cleaned, the cleaning may be performed in combination with other cleaning processes such as cleaning the entire outer periphery.

As explained above, according to the present invention, since the ejection passage is formed to communicate with the fluid chamber via the fluid intake part, it is possible to completely remove burrs etc. that occur during manufacturing process, and the fluid chamber The flow of fluid from the to the ejection passage becomes smooth, and clogging in the ejection passage can be prevented. Even if foreign matter such as chips adheres to the ejection path and causes clogging, the clogging can be easily removed. Furthermore, even if a longer nozzle or a wider nozzle is required in terms of size and shape, this can be easily accommodated in terms of design.
