Problems solved by technology

Although this hanger can keep the workpiece in a fixed position throughout the electrophoresis process, there are still many technical defects, such as,
[0005] 1. The position of the pointed protrusion must be very accurate, otherwise the workpiece cannot be hung up, or the workpiece will be damaged if it is clamped too tightly, which brings great difficulty to the processing;
[0006] 2. There must be a large contact area between the pointed protrusion and the workpiece to overcome the self-weight of the workpiece, otherwise the workpiece will slip off, which leads to a large hanging point on the surface of the workpiece after electrophoresis, which affects its anti-corrosion and insulation properties;
[0007] 3. Since the wall of the workpiece is very thin, it is easy to cause deformation of the workpiece during mounting;
[0008] 4. Since each workpiece is supported by or in contact with three pointed protrusions, it can only be mounted separately, so the mounting efficiency is very low

Embodiment 1

[0031] Embodiment 1 (taking the annular workpiece as example):

[0032] Such as Figure 3 to Figure 5 As shown, an electrophoretic coating fixture includes several saw blades 1 arranged side by side, and all the saw blades 1 are connected by connecting pieces 9 . For better stability of the fixture, generally at least two connecting pieces 9 are used.

[0033] The method for using the above-mentioned electrophoretic coating fixture includes the following steps:

[0034] a. Lay the jig flat, and the direction of the teeth of the saw blade is upward;

[0035] b. Place the workpiece flat on the saw teeth;

Embodiment 2

[0036] Embodiment 2 (taking the annular workpiece as example):

[0037] Such as Figure 6 to Figure 8 As shown, an electrophoretic coating fixture includes a number of saw blades 1 side by side, and the two ends of all saw blades 1 are respectively connected by connecting rods 2. Specifically, holes 4 are opened at both ends of the saw blade 1, and a connecting rod 2 Pass through the holes 4 at one end of all saw blades 1 in turn and be fixedly connected with the saw blades, and another connecting rod 2 pass through the holes 4 at the other ends of all saw blades 1 in turn and be fixedly connected with the saw blades, and the saw blade 7 of the saw blade 1 is provided with reinforcing ribs 8. The distance between adjacent saw blades 1 is smaller than the diameter of the workpiece 5, and the two ends of the connecting rod 2 are connected with hanging ears 3. When using this embodiment, it is sufficient to place the workpiece 5 flat on the saw teeth 6 of the saw blade 1 .

Abstract

The invention discloses a electrophoresis painting fixture and a method of application, and is a technology field of work holder, the electrophoresis painting fixture includes several side-by-side saw blade fixed by connecting piece; the method of application includes the step of the fixture keeps flat with the saw tooth of saw blade upward, then the work piece flats on the top saw tooth, etc.; the invention has working simply, small hanging point and high production efficiency, the work piece is not deformed because of hanging. The invention not only applies to clamping for the ring magnet workpiece, but also to clamping for other non-magnet ring workpiece, flake workpiece, and other electrophoresis coating parts.

Description

technical field [0001] The invention relates to a workpiece fixture for electrophoretic coating. Background technique [0002] At present, the corrosion resistance and insulation of most motor components are achieved by electrophoretic coating on their surfaces. In the electrophoretic process, after electrophoresis to form a coating with a predetermined thickness on the surface of the workpiece, it is then baked in a baking furnace. However, in the existing electrophoretic coating processes, the clamping of the ring magnet workpiece is Adopt hook type or spring clip method. [0003] The hook-type fixture is hook-shaped, and the ring-shaped workpiece 2' can be hung on the hook 1' (as shown in Figure 1). With this hook-type fixture, after electrophoresis, the hanging point on the inner ring surface of the workpiece is obvious , affecting its anti-corrosion performance, especially the magnet ring-shaped workpieces installed in optical drives and hard disks mostly use the inne...
