Description

The present invention relates to a coating rack. For example, in the case of manufacturing a rotor for a motor, a powder material is molded into a predetermined shape, a molded product is cured, then the cured product is electrodeposited, and finally the electrodeposit is magnetized. . A coating rack is used for such electrodeposition coating. The present invention relates to the improvement of the above-mentioned coating rack.

<Prior art and its problems> Conventionally, a coating rack in which a plurality of locking pieces are attached to each of a plurality of horizontal rails arranged side by side at an interval from each other has been used. The coating rack uses the repulsive force of the locking pieces to paint the workpieces one by one or one pair of the locking pieces when using this to paint the workpiece. After manually attaching and painting, one by one or one pair of locking pieces is used to manually remove the painted object one by one. Needless to say, such a conventional painting rack has a problem that workability is poor.

<Problems to be Solved by the Invention, Means for Solving the Problems> The present invention provides an improved coating rack that solves the above-mentioned conventional problems.

Thus, the present invention provides a fixed support member having a plurality of main cross rails juxtaposed at a distance from each other, and a lower support member or an upper strut having a plurality of main cross rails arranged side by side in the same direction as the main cross rails. A movable support member having a plurality of sub-cross rails is slidably mounted along the main cross rail, and a spring is interposed between the fixed support member and the movable support member; A plurality of locking pieces forming a pair between them are attached to the main horizontal rail and the sub horizontal rail, and the object to be coated is supported by the locking pieces forming a pair by the repulsive force of the spring. The present invention relates to a coating rack comprising:

The coating rack according to the present invention includes a fixed support member, a movable support member slidably attached to the fixed support member, and a spring interposed between both.
The fixed support member has a plurality of main cross rails arranged side by side at an interval from each other, and the movable support member also has a plurality of auxiliary cross rails arranged at a distance from each other in the same direction as the main cross rail. It has a crosspiece. The movable support member is slidable in the direction along the main horizontal rail with respect to the fixed support member, and the spring applies a repulsive force in the direction along the main horizontal rail.
A plurality of locking pieces forming a pair between them are attached to the main horizontal rail and the sub horizontal rail, and the workpiece is supported by the locking pieces forming a pair by the repulsive force of the spring. Has become.

For example, when the cured product is subjected to the electrodeposition coating using the coating rack according to the present invention as described above, the coating is performed as follows.
First, the movable support member is pressed against the repulsive force of the spring, and the locking piece attached to the main horizontal rail of the fixed support member and the locking piece mounted to the sub horizontal rail of the movable support member To reduce the interval. Next, a plurality of locking pieces forming a pair in the above-described state are inserted into the plurality of cured products arranged in advance at a predetermined interval from the upper side thereof. Finally, when the pressing on the movable support member is released, the locking piece attached to the main horizontal rail of the fixed support member and the locking piece mounted on the sub-horizontal rail of the movable support member by the repulsive force of the spring. And the plurality of locking pieces forming a pair abut against the inside of the plurality of cured products to support the plurality of cured products. Conversely, a plurality of locking pieces forming a pair can be brought into contact with each other from the outside of the plurality of cured products to support the plurality of cured products.

Thus, the plurality of cured products are supported by the coating rack, and the plurality of cured products are immersed in the coating liquid in a state where the coating rack is suspended using hooks and rings formed on the fixed support member. Then, when the electrodeposition coating is to be removed from the coating rack after the electrodeposition coating, the movable support member is pressed against the repulsive force of the spring as described above to form a pair. What is necessary is just to narrow the space | interval of each of several locking pieces. The following is this repetition.

As described above, when the cured product is subjected to the electrodeposition coating, it is needless to say that the locking piece is made of a conductive material. In order to prevent the cured product from being damaged when abutting against the inside or outside of the cured product and supporting the cured product, the locking piece is made of a flexible material having a repulsive force. Is preferred,
Also, when suspending the coating rack, the movable support member is moved to the fixed support member so that the weight of the movable support member is not applied to the cured product via the locking piece and the cured product is not damaged. More preferably, a restricting stopper is attached.

Hereinafter, the configuration of the present invention will be described in more detail with reference to the drawings.
