Description

[Detailed Description of the Invention] The present invention relates to a clamping vibration device for a washing machine.

Items with complex structures after casting or machining, such as automobile parts with internal recesses or passages such as cylinder heads, should be cleaned with cleaning fluid to remove casting sand and cutting waste after machining. There is. However, in this method, a large number of high-pressure nozzles are usually disposed facing the object to be cleaned (such as a cylinder head) that is left still, and the object is cleaned with cleaning liquid sprayed from each nozzle. Therefore, desired cleaning can be carried out on the outer surface of the object to be cleaned or shallow depressions formed in a continuous manner on the outer surface, but it is difficult to clean the outer surface of the object to be cleaned or the shallow depressions formed in a continuous manner on the outer surface. Cleaning of hollows, etc., which were difficult to reach, was insufficient.

In view of this, the present invention was devised in order to reliably clean even articles having a complicated structure.The present invention will be explained below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes a frame of the clamping vibrating device, which is installed at a predetermined position in the washer that can perform continuous automatic cleaning as shown in FIG. It is suspended and supported so that it can slide vertically, that is, go up and down. The frame 1 is supported by the lower end of a rod 4 of a cylinder 3 (preferably an air cylinder, etc.) fixed to a frame 2 on the main body F, and the frame 1 is raised and lowered by a predetermined stroke by operating the cylinder. At the frame lowering position, the object to be cleaned is held between the objects fed into the washing machine, or the object is released after washing.
Even if the object to be cleaned is rotated and vibrated at the elevated position, the object is cleaned so as not to come into contact with a carry-in conveyor, etc.

A spline shaft 6 is rotatably supported on the lower surface side of the frame 1 via a bearing 5, and a holding frame 7 for holding and rotating an object to be cleaned is attached to both ends of the spline shaft 6 along the spline shaft. They are provided so as to be slidable and rotatable and facing each other. This clamping frame 7 is slidably inserted and suspended at the end of the spline shaft, and a clamping plate 8 is provided inside the lower end of each frame 7 so as to be applied to both sides of the object to be cleaned and to clamp it. The holding plates 8 are formed to match the shape of the object to be cleaned, and the inner surface is provided with 1 or 2 holes so as to spray the cleaning liquid into the passages and depressions formed in the object to be cleaned. A plurality of nozzles (not shown) are provided, and the cleaning liquid is supplied from a part of the clamping frame 7 to the clamping plate 8 from inside the frame 7.
The liquid is sprayed from the nozzle toward the passageway, recess, etc. of the object to be cleaned. Furthermore, this clamping plate 8 is rotatably supported by the frame 7.

This rotation of the clamping plate 8 causes the outer side of the supporting part of the clamping plate to protrude outward from the clamping frame, and the gear 9
This gear 9 is meshed directly or via an idler 11 with a gear 10 that is slidably fitted to the spline shaft together with a clamping frame, and the rotation of this spline shaft is controlled by the gears 10, 9 or 10, 11, and 9.

The spline shaft 6 is equipped with a bevel gear 12,
This gear 12 meshes with a bevel gear 13 provided at the lower end of a drive shaft 14 supported by the main body F, and the drive shaft 14 is driven by a drive device 15 via a shaft 16 equipped with a universal joint, a bevel gear device 17, etc. do. The clamping plate 8, which is driven by this drive device 15 via a drive shaft, spline shaft, gear group, etc., is driven at a predetermined rotation speed, but in this case, the rotation direction may be the same. It is also possible to switch between forward and reverse rotation at regular intervals.

Furthermore, in order to slide the clamping plates 8, 8 in the approaching and separating directions along the spline shaft, links 19 are respectively engaged with support shafts 18 protruding from the upper part of the clamping frame 7, as shown in FIGS. 3 and 6. , the ends of both links are pivotally connected to both ends of the lever 20, and the lever 2
A swinging shaft 21 fixed to the center of 0 projects above the main body F, and a lever 2 protrudes from the upper end of this swinging shaft 21.
2 is engaged with the rod of a cylinder 23 provided on the main body F, and by operating the cylinder 23, the lever, swing shaft,
The holding frames that face each other via links, etc., are slid in the direction toward and away from each other along the spline shaft. The amount of movement of the clamping plate installed on the clamping frame can be set in advance so that it can alternately clamp and release the object to be cleaned, but it is possible to set the amount of movement of the clamping plate installed in the clamping frame so that it can alternately clamp and release the object to be cleaned. Good too.

Furthermore, vibrations are applied to the object to be cleaned, which is rotatably held between the holding disks, in order to improve the cleaning effect, and this vibration device is shown in detail in FIGS. 5 and 7.

In this vibrating device, a vibrating disk 27 is fixed to a part of a rod 4 that suspends and supports a frame 1 so that it can be raised and lowered, and an eccentric shaft 24 equipped with a roller 25 at the tip is provided opposite to the surface of the vibrating disk. By driving the shaft 24 with the drive device 26, the eccentric shaft 24 pushes down the vibration plate via the roller 25 and releases the pushing force, thereby causing the frame held in the raised position by the air cylinder. 1 is vibrated in the vertical direction by the pressing force of the cylinder and the vibration plate, and this vibration frequency is determined by the rotation speed of the eccentric shaft, which depends on the shape of the object to be cleaned, the degree of cleaning, and the cleaning time. etc. may be determined as appropriate.

Although not shown, the outer surface of the object to be cleaned is simultaneously cleaned by jetting cleaning water from a number of nozzles provided toward each surface of the object.

According to the present invention, a nozzle is provided on a holding plate for holding an object to be cleaned so that the object to be cleaned is held and the washing water is sprayed directly into the passageway or recess leading to the inside, and the rotating movement is performed while holding the object. Since it applies vibrations and vibrations, it is possible to effectively clean even the deep parts of the object to be cleaned even if it has a complicated shape, which has the advantage that the cleaning effect is significantly improved compared to the conventional method.
