BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0014]
[Embodiment 1]
1 is a front view, and FIG. 2 is a side view of FIG. The upper end of the suspending member 1 for suspending the workpiece W is supported by a horizontally disposed electrode 2. The electrode 2 is insulated and fixed to the support member 2a, and the support member 2a is fixed to the frame 13. In order to support the hanging member 1 on the electrode 2, a hanger 3 is provided on the electrode 2, and a metal ring 4 connected to the upper end of the hanging member 1 is hooked on the hanger 3. The workpiece W is bound by the hanging member 1. Here, as the hanging member 1, an aluminum wire rod or the like, which is not affected by the processing liquid L in the processing tank 5, is selected.
[0015]
In the present example, the number of the hanging members 1 is two, but one or more necessary members are used depending on the shape of the workpiece W. Each of the two workpieces W is connected to a common hanging member 1. The hanging member 1 may also serve as a conductive member that connects the electrode 2 and the workpiece W as conductive. In this example, the electrode 2 and the workpiece W are loosely coupled by the conductive member 1a. This conductive member 1a is an aluminum wire. As the conductive member 1a, another material may be used as long as it has conductivity and flexibility. The hanging member 1 may be a string, a wire, a chain, or any other member capable of freely swinging the workpiece W in a suspended state.
[0016]
The auxiliary tool 6 is made of an insulating material such as a modified PPE (polyphenylene ether) material in a ladder shape, and the horizontal shaft 6a at the upper end is rotated by a bearing 7b provided at the lower end of a hanger 7a fixed to the bracket 7 and hanging therefrom. The auxiliary tool 6 is freely hung on the bracket 7 and is swingable about a horizontal shaft 6a.
[0017]
The auxiliary tool 6 and the workpiece W are connected by a wire 8. The wire 8 is not particularly limited, as long as the auxiliary tool 6 and the workpiece W are connected. In this example, the wire 8 is used to stretch the wire 8 toward one side from the lower end of the workpiece W.
[0018]
The driving means 9 for swinging the auxiliary tool 6 will be described. The auxiliary tool 6 includes a clevis-type air cylinder 12 having a piston rod end pivotally attached to an arm 11 fixed or integrally provided at the center of a shaft 6a of the auxiliary tool 6, and a cylinder rear end connected to a bracket 7.
[0019]
The bracket 7 is attached to a frame 13 that supports the entire apparatus. The electrode 2 is fixed to the frame 13. The frame 13 may be regulated so as to be able to move up and down vertically by a vertical guide means.
[0020]
A compressed air pipe is provided to the air cylinder 12 from a compressed air source 14 via a controller 15 including a switching valve.
[0021]
The frame 13 is suspended by a hoist (not shown) and moves up and down, so that the entire apparatus including the processing object W is immersed in the processing liquid L in the processing tank 5 and a position above the processing tank 5. You can take the position of the space.
[0022]
The operation in the above will be described. The entire apparatus is at the upper limit position by lifting the frame 13 with a hoist, and all are in the air. In this state, the workpiece W is bound by the suspending member 1 and the ring 4 is hung on the hanger 3 to suspend the workpiece W. Next, the workpiece W and the auxiliary tool 6 are connected with the wire 8. This tying method may be tightly bound or loosened. Next, the electrode 2 and the workpiece W are joined by the conductive wire member 1a. The workpiece W is lowered and stopped by the hoist (not shown) until the workpiece W is completely immersed in the processing liquid L while the frame 13 is suspended. Here, as shown in FIG. 2, the assisting tool 6 is hung down and remains vertical, and the air cylinder 12 has a piston at an intermediate position. The object to be processed W is suspended by the suspension member 1 descending from the electrode 2 and is oriented substantially vertically. In FIG. 1, the above-mentioned workpiece W is supported and, at the same time, the above-mentioned workpiece W is suspended so that the hanging member 1 which is oriented vertically is further tensioned. Is hanging. In FIG. 1, the conductive member 1a on the right side is loosely coupled from the electrode 2 to each workpiece W and is in a conductive state.
[0023]
Here, the air cylinder 12 expands and contracts with the compressed air which is alternately sent from the compressed air source 14 to the left and right cylinder chambers via the switching valve, whereby the arm 11 swings about the shaft 6a of the assisting tool 6, thereby The shaft 6a swings in the bearing 7b, and swings the assisting tool 6 from the position shown in FIG. With this swing, the workpiece W connected by the wire 8 swings around the hanger 3 while being hung by the hanging member 1.
[0024]
Due to such swinging, even if there is an air pocket in the workpiece W, this pocket is eliminated. Since the workpiece W is hung by the hanging member 1, this apparatus can be used regardless of the difference in size and shape, and there is no need for a jig for adjusting the workpiece W. Since the auxiliary tool 6 has a ladder shape, it is only necessary to connect the workpiece W and the auxiliary tool 6 irrespective of the size and the shape of the workpiece W. If the hanging member 1 and the conductive member 1a are also used, the number of members can be reduced. In particular, the auxiliary tool 6 is formed only by assembling a heat-resistant and chemical-resistant resin material in a ladder shape, which significantly reduces the overall equipment cost.
[0025]
【Example】
The aluminum stub beam of the workpiece W is an anode, and the polarity of the processing liquid L is a cathode.
[0026]
【The invention's effect】
According to a first aspect of the present invention, an object to be processed is suspended in a liquid to be processed by a suspending member, and a swingable auxiliary tool and an object to be processed are coupled with the upper end along the object to be processed as a fulcrum. Since the object to be processed is swung, (1) the object to be processed can be used as it is without changing the apparatus for the difference in size and shape of the object. (2) An object to be processed after completion of another process is simply hung on a frame with a hanging tool, and the object to be processed and an auxiliary tool are simply connected by a connecting member. No work. (3) It is only driven by a simple auxiliary tool, and the equipment cost is very low.
[0027]
According to a second aspect of the present invention, in the first aspect, since the electrodes are provided horizontally, a coupling portion of the conductive wire member can be easily selected, and a place which does not obstruct the swing of the workpiece can be appropriately selected. .
[0028]
In the third invention according to the present application, since the hanging member also serves as the conductive wire member in the first invention, it is only necessary to hang the object to be processed on the electrode.
[0029]
The fourth invention according to the present application can correspond to an anodizing solution because the conductive member is an aluminum wire in the first invention.
[0030]
In the fifth invention according to the present application, since the hanging member is a wire, the degree of freedom for swing is large and the object to be processed can be bound as it is.
[0031]
The sixth invention according to the present application can provide a relatively inexpensive device by using the heat-resistant and chemical-resistant resin material in the first invention.
[0032]
According to a seventh aspect of the present invention, in the first aspect, an arm is provided on the auxiliary tool, and the arm and the frame are connected by a clevis-type air cylinder. Since the direction of the swing is changed by the assisting tool at the end of the swing at a rapid speed, the effect of removing air bubbles from the object to be processed is large.
[0033]
According to an eighth aspect of the present invention, in the first aspect, the electrode is used as a frame by forming the electrode as a part of the frame. Therefore, the object to be processed can be hung on the electrode.
