Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention involves plating small parts (materials) inside the plating bath while rotating or inverting them at a predetermined angle. The present invention relates to the structure of the lid of the plating basket.

``Prior Art'' FIG. 3 shows the structure of the lid of a conventional general plating basket.

A basket is formed by fixing end plates 2 made of synthetic resin to both ends of a body 1 made of a liquid-permeable synthetic resin made of a polygonal cylindrical perforated plate, etc., and an opening 3 is formed by opening the upper side surface. After filling the opening 3 with a plating material (not shown), the portion other than the peripheral edge 41 is covered with a cover 4 made of a liquid-permeable material such as a perforated plate. The flat upper surface of the peripheral edge 3a of the opening 3 and the lower surface of the peripheral edge 41 of the cover 4 are overlapped,
Horizontal guide holes 31 are formed at predetermined intervals in the protruding walls 3b on both sides formed on the outer edge of the portion of the peripheral portion 3a along the body 1, and both ends of the presser plate 42 are inserted into each of the guide holes 31 at the predetermined intervals. The cover 4 was guided and pressed against the periphery of the opening by means of a push screw attached to a presser plate 42.

"Problems to be Solved by the Invention" In the conventional cover described above, the peripheral frame 41 of the cover 4 and the peripheral edge 3a of the opening 3 are simply overlapped in a two-dimensional manner. Peripheral part 4
If a gap leading to the inside of the basket is created between the peripheral edge 3a of the opening 3 and the peripheral edge 41, the plating material will enter the gap between the peripheral edge 41 and the peripheral edge 3a, making it difficult to apply uniform plating. This has disadvantages in that it impedes the movement of the cover 4 and further promotes deformation of the cover 4.

The purpose of the present invention is to prevent the plating material from entering between the peripheral frame of the cover and the peripheral edge of the opening, so that the plating material can be plated more uniformly as a whole, and at the same time, the deformation of the cover can be further suppressed. The object of the present invention is to provide a cover structure that allows

"Means for Solving the Problem" A groove is formed on the peripheral edge of the opening that abuts the lower surface of the peripheral edge of the cover, and a protrusion guided to the groove is formed on the lower surface of the peripheral edge of the cover. forming a downward groove that fits with the inner protruding wall of the groove, and forming an appropriate number of notches or holes communicating with the outside of the groove in the outer protruding wall or the inner protruding wall of the groove at the peripheral edge of the opening; The bottom level of the hole or notch is set to be the same as or lower than the bottom level of the groove of the opening.

"Operation" Since the inner protruding wall of the groove at the periphery of the opening and the downward groove at the periphery of the cover fit together,
There is no gap between the peripheral edge of the cover and the peripheral edge of the opening where the plating material can enter. Additionally, if the plating material gets into the groove at the periphery of the opening when taking it in or out, the material that entered the groove should be removed from the basket through the hole or notch formed on the outer or inner vertical wall of the groove. Can be released internally or externally.

"Embodiment" A preferred embodiment of the cover structure according to the present invention will be described with reference to FIGS. 1 and 2.

1 is a polygonal cylindrical body with numerous small holes 11.
It is formed into a hexagonal cylinder shape by combining liquid-permeable material plates such as perforated synthetic resin plates.
A basket is constructed by bonding circular end plates 2 to both ends. One of the end plates 2 at both ends also serves as a gear for receiving rotational force from a drive source (not shown), and a material having liquid permeability may also be used for both end plates. In addition to the case where a perforated plate as described above is used for the body part 1, there is also a case where one side of the perforated plate is covered with a net.

The body 1 is provided with an opening 3 whose entire upper surface is open for taking in and out plating material (not shown), and a cover 4 is attached to the opening 3.

A groove 32 is formed on the upper surface of the frame-shaped peripheral edge 3a of the opening 3.
is formed on the outer protruding wall 3b of the groove 32.
Holes 33 communicating with the outside of the grooves 2 are formed at appropriate intervals, and the bottom level of the holes 33 is set to be equal to or lower than the bottom level of the groove 32. Second
As shown in the figure, at both ends of the body 1, the end plates 2 also serve as the outer protruding walls 3b of the groove 32, so the end plates 2
A hole 3 that also communicates with the outside of the groove 32 (in the outer projecting wall 3b)
3 is formed.

The cover 4 is composed of a frame-shaped peripheral part 41 made of synthetic resin and a perforated plate 45 made of synthetic resin fixed to the peripheral part 41. On the lower surface of the peripheral part 41, the peripheral part 3a of the opening 3 is formed. Projection 43 guided to groove 32
and a downward groove 4 that fits into the inner protruding wall 34 of the groove 32.
4 is formed.

Reference numeral 5 denotes a synthetic resin holding plate formed into a T-shape in plan view, which is guided through a guide hole 31 formed in the outer projecting wall 3b of the T-shaped both ends 51, 51 groove 32, and is guided by the T-shaped tip. The portion 52 is guided into a guide hole 31 formed in the end plate 2 which also serves as the outer protruding wall 3b of the groove 32, and the lid 4 is held down by a push screw 6 provided at the center portion. In the push screw 6, a screw shaft 61 is screwed to the presser plate 5, a collar 62 for pressing a reinforcing plate 46 provided on the lid 4 is fixed to the tip of the screw shaft 61, and the reinforcing plate 46 is further rotated to the tip. A shaft 63 that freely moves through the lid 4 is fixed, and a flange 64 is welded to the tip of the shaft 63 to prevent the set screw 6 and presser plate 5 from coming off the lid 4. Reference numeral 53 is an adjustment screw for maintaining an appropriate gap between the presser plate 5, the reinforcing plate 46 of the lid 4, and the peripheral edge 41.

The lid 4 is opened by loosening the push screw 6, rotating the press plate 5, and removing each end 51, 51 and 52 of the press plate 5 from the guide hole 31.

The cover structure of this embodiment includes a downward groove 44 formed on the lower surface of the peripheral edge of the lid 4 and a peripheral edge 3a of the opening 3.
The inner protruding wall 34 of the groove 32 is fitted, and this part forms a drop-lid.
Even if the lid 4 is slightly deformed, no gap is created between the peripheral edge 41 of the lid 4 and the peripheral edge 3a of the opening 3 in which the plating material can enter. Furthermore, even if the plating material enters the groove 32 of the peripheral edge 3a when taking it in or out of the basket, the hole 33 that communicates with the groove 32 is formed in the outer projecting wall 3b.
Material can be easily removed from the groove 32 through.

In the embodiment, the outer protruding wall 3b of the groove 32
Although the hole 33 is formed in the outer projecting wall 3b, the hole 33 can be formed by a notch that reaches the upper end of the projecting wall 3b, and instead of forming the hole 33 in the outer projecting wall 3b. Alternatively, cutouts communicating with the inside of the basket may be formed at appropriate intervals in the inner projecting wall 34.

Further, the body portion 1 is not limited to a hexagonal tube shape, but can also be implemented with other polygonal tube shapes, and further,
For example, it is also possible to use a deformed polygonal cylinder in which the bottom surface of the body 1 shown in FIG. 1 has a mountain-shaped cross section.

"Effects of the Invention" The cover structure according to the present invention has a groove formed on the peripheral edge of the opening that contacts the lower surface of the peripheral edge of the cover, and a protrusion guided to the groove on the lower surface of the peripheral edge of the cover. Since a downward groove is formed to fit with the inner protruding wall of the groove, even if the lid is slightly deformed, there will be no gap where the plating material can enter between the peripheral edge of the lid and the opening. Does not occur. Further, an appropriate number of notches or holes communicating with the outside of the groove are formed in the outer projecting wall or the inner projecting wall of the groove at the peripheral edge of the opening, and the bottom level of the hole or notch is set at the bottom level of the groove of the opening. Since the level is set to be the same as or lower than the bottom level, even if the plating material gets into the groove at the peripheral edge of the opening and becomes clogged, it can be easily discharged from the groove through the hole or notch.
