[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanger for plating which is devised so as to easily perform air bleeding in a plating bath and draining after removing from the plating bath.

[0002]

[Prior art]

 There are various types of plating hanger jigs, but as shown in Japanese Utility Model Publication No. 5-12290, it is common to provide a work holding means inside the hanger frame. In the plating hanger jig disclosed in Japanese Utility Model Publication No. 5-12290, there is no particular problem because the work is flat, but when the work is box-shaped, it can be used in the plating bath. At this time, air bubbles may accumulate inside the work, causing poor plating. When the work is box-shaped, the plating solution may collect inside the work even after the work is taken out of the plating bath together with the plating hanger jig.

For this reason, by devising the entire plating hanger jig to tilt or vibrate up and down, it has been devised to smoothly remove air from the work in the plating bath and drain the work after taking out from the plating bath. ing. However, when the plating hanger jig is large, the size of the device is large in order to move the entire hanger jig, and it is impossible to adjust its movement in small increments according to the workpiece. There was also a drawback that it was.

[0004]

[Problems to be solved by the device]

 The present invention has been made to solve the above-mentioned conventional problems, and to provide a plating hanger jig capable of smoothly performing air bleeding and draining of a work without requiring a large-scale device. It is a thing.

[0005]

Means for Solving the Problems The present invention has been made to solve the above problems. In the present invention, an oscillating frame having a work holding means is axially supported by a shaft inside a hanger frame, and an upper part of the hanger frame is provided. In addition, a motor for swinging the swing frame around the shaft via a link mechanism is provided.

[0006]

[Action]

 The plating hanger jig of the present invention is used by holding the work on the work holding means of the swing frame, and the swing frame is connected to the swing frame by the motor provided on the upper part of the hanger frame. It can be swung about an axis. Therefore, if the plating hanger jig is immersed in the plating bath and the work is rocked together with the rocking frame, the air inside the work can be bleeded, and the plating hanger jig can be plated. The work can be drained by rocking the work together with the rocking frame with the work being lifted from the bath. Moreover, by changing the number of rotations of the motor, it is possible to make small adjustments to the swing speed, etc. according to the type of work.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. In FIG. 1, reference numeral 1 is a portal-shaped hanger frame, and 2 is a quadrangular rocking frame that is axially supported by a shaft 3 inside the hanger frame 1. In the embodiment, three swing frames 2 are provided, but the number can be set appropriately.

As shown in FIGS. 2 and 3, a plate 4 projecting rearward of the hanger frame 1 is fixed to one side frame of each swing frame 2, and a tip portion of each plate 4 is fixed. A first link 6 is attached to the shaft 5. The upper end of the first link 6 is bent at a right angle to the hanger frame 1. On the other hand, a motor 7 is attached to the upper part of the hanger frame 1, and a second link 9 is connected between the tip of the crank 8 fixed to the output shaft of the hanger frame 1 and the upper end of the first link 6. There is. With the link mechanism configured as described above, when the motor 7 is rotated, the second link 9 is moved up and down, the first link 6 is moved up and down, and the rocking frames 2 are rocked about the shafts 3 described above. Becomes This is shown in phantom in FIG. Since the motor 7 is provided above the hanger frame 1, the operation of the motor 7 is not hindered even when the hanger frame 1 is immersed in the plating bath.

Each swing frame 2 is provided with a work holding means 10, respectively. In the embodiment, the upper swing frame 2 has a large number of power feeding clips 10a capable of holding the box-shaped work W at an angle, and the tip of the power supply clip 10a is pierced into the hole of the work W. Further, the swing frame 2 in the middle stage is provided with a large number of power feeding clips 10b capable of holding the box-shaped work W horizontally. Further, the lower swing frame 2 is provided with a bar-shaped power feeding clip 10c capable of bolting the box-shaped work W. The power supply clips 10a, 10b, 10c serving as the work holding means 10 have two roles of supplying power to the work W and holding the work. Although three types of work holding means 10 are shown in the embodiment, it goes without saying that the common work holding means 10 may be provided for all the swing frames 2. As shown in FIG. 1, in this embodiment, all the works W are held in a zigzag manner so that the shadow of the plating does not occur.

In the plating hanger jig of the embodiment thus configured, the work W is held by the work holding means 10 of each swing frame 2, and the upper end of the hanger frame 1 is lifted by the hanger of the plating apparatus. It is the same as the conventional method that the plating process is performed by immersing it in the plating tank. However, by driving the motor 7 as described above, each rocking frame 2 can be rocked about the shaft 3 in the plating bath, so that air can be removed from the inside of the box-shaped work W. You can Therefore, it is possible to prevent plating failure due to the accumulation of air inside the work W.

After the plating process, the swinging frames 2 are swung around the shaft 3 in a state where the plating hanger jig is pulled up from the plating bath, so that the plating solution accumulated inside the box-shaped work W is removed. Draining can be sufficiently performed. In particular, if the work W is held obliquely like the upper swing frame 2, it is possible to improve the air bleeding property and the liquid draining property in the horizontal direction that is perpendicular to the swinging direction. The work holding means 10 such as the middle and lower stages has the advantage that the work W can be easily attached and detached by the robot.

[0012]

[Effect of device]

 As described above, in the plating hanger jig of the present invention, the swing frame 2 is swung by the motor 7. Therefore, compared with the conventional hanger frame that swings the entire hanger frame. It does not require a large-scale device and can smoothly deaerate and drain the work. There is also an advantage that the swinging motion can be adjusted in a small amount according to the work W by adjusting the rotation speed of the motor 7. Therefore, this proposal is of great practical value as a plating hanger jig that solves the conventional problems.
