Abstract

A clamping device of electrophoretic coating is characterized in that the utility model comprises a plurality of saw blades (1) arranged in parallel, which are connected fixedly by a connector (9).

Description

Electrophoresis painting clamp

Technical field

The utility model relates to a kind of workholder of electrophoretic painting.

Background technology

At present, the erosion resistance of most of motor component and insulativity are all by realizing at its surperficial electrophoretic coating.In electrophoresis process, after forming the coating of pre-determined thickness, and then be exactly to enter in the roaster to toast, and in existing these electrophoresis coating techniques at the workpiece surface electrophoresis, all be the mode that adopts hook-hang type or spring jig for the clamping of annular magnet workpiece.

The hook-hang type anchor clamps are hook-shaped, annular work piece 2 ' hang over hook 1 ' go up is got final product (as shown in Figure 1), adopt this hook-hang type anchor clamps, after the electrophoresis, the hanging point of ring surface clearly influences its antiseptic property in the workpiece, and the magnet annular work piece that especially is loaded in CD-ROM drive and the hard disk is the annular inner portion of utilizing workpiece mostly, the antiseptic property that has just more reduced, and then the work-ing life of having reduced workpiece and CD-ROM drive/hard disk.

The mode of spring jig is to adopt spring piece or spring wire with the annular work piece clamping, such as notification number is that CN1073754C, the patent No. are " workpiece holding frame " (as shown in Figure 2) of being explained in 95115288.2 the patent to be exactly the mode of this spring jig that adopts, this workpiece holding frame comprise a back up pad 3 ', that back up pad is provided with that many reeds or other materials make is pointed protruding 4 ', each workpiece 2 ' by three pointed protruding 1 ' support or with three pointed protruding 1 ' contact.Though can still there be a lot of technological deficiencies in this hanger so that workpiece remains on the fixed position in whole electrophoresis process, such as,

1, the position of pointed projection must be very accurate, otherwise workpiece can not hang up, or hold too tight defective work piece, and this has brought very big difficulty to processing;

2, pointed projection and workpiece must have bigger contact area overcoming workpiece deadweight, otherwise workpiece will slippage, has so just caused after the electrophoresis, and the hanging point of workpiece surface is very big, influences its anticorrosion and insulating property;

3, because workpiece wall is very thin, when mounting, be easy to cause workpiece deformation;

4, since each workpiece support by three pointed projectioies or contact with three pointed projectioies, can only mount separately, thereby it is very low to mount efficient.

The utility model content

In order to overcome the deficiency of existing workpiece electrophoresis anchor clamps, the purpose of this utility model is: provide that a kind of processing is simple, hanging point is little, workpiece can not be out of shape because of mounting, electrophoresis painting clamp simultaneously highly efficient in productivity.

The technical solution of the utility model is: a kind of electrophoresis painting clamp, comprise that saw blade side by side is some, and all saw blades are connected by web member.

Spacing between the adjacent saw blade is less than the maximum physical dimension of workpiece.For annular work piece, the spacing between the adjacent saw blade is less than the diameter of annular work piece.To guarantee that workpiece can be placed on the saw blade reposefully.

The two ends of described all saw blades are connected by union lever respectively.

The two ends of described saw blade have the hole, and the Kong Bingyu saw blade that two union levers pass all saw blade two ends respectively successively is connected.Increased the stability that is connected between the saw blade and union lever in the anchor clamps.

The saw blade of described saw blade is provided with stiffening web, to strengthen the rigidity of saw blade.

The two ends of described union lever are connected with hangers, are convenient to the carrying of anchor clamps, and are transplanted on next station from a station on the production-lines.

The beneficial effects of the utility model are: processing is simple, and the workpiece hanging point is little after the completion of processing, and workpiece keeps flat in electrophoresis process all the time, and workpiece can not be squeezed, thereby can not be out of shape because of mounting, and uses the utility model to enhance productivity greatly.

Below in conjunction with the drawings and specific embodiments the utility model is further specified.

Embodiment

Embodiment 1 (is example with the annular work piece):

To shown in Figure 5, a kind of electrophoresis painting clamp comprises that saw blade 1 side by side is some as Fig. 3, and all saw blades 1 all pass through web member 9 and connect.For the stationarity of anchor clamps is good, at least two web members 9 of general employing.

Embodiment 2 (is example with the annular work piece):

Extremely shown in Figure 8 as Fig. 6, a kind of electrophoresis painting clamp, comprise that saw blade 1 side by side is some, all saw blade 1 two ends all connect by union lever 2 respectively, specifically, the two ends of saw blade 1 have hole 4, union lever 2 passes the hole 4 of all saw blade 1 one ends successively and is connected with saw blade, another root union lever 2 passes the hole 4 of all saw blade 1 the other ends successively and is connected with saw blade, the saw blade 7 of saw blade 1 is provided with stiffening web 8, spacing between the adjacent saw blade 1 is less than the diameter of workpiece 5, and the two ends of union lever 2 are connected with hangers 3.When using present embodiment, workpiece 5 is lain against on the sawtooth 6 of saw blade 1 and get final product.

Owing to can not making workpiece be squeezed, anchor clamps described in the utility model do not cause distortion or damage, so the shape-holding property of workpiece is good; Be installed conveniently, only need workpiece steadily is positioned on the sawtooth of saw blade and get final product, thereby production efficiency is improved greatly; And,,, do not influence the non-corrosibility and the insulativity of workpiece basically so the hanging point on the workpiece is very little after the completion of processing because the bottom surface and the sawtooth contact surface of workpiece are very little.

It is to be noted, though the foregoing description describes structure of the present utility model, feature and function in detail, but be not limited in said structure, such as, the saw blade of electrophoresis painting clamp of the present utility model can have multiple arrangement according to actual needs, also multiple mode of connection can be arranged between saw blade and the union lever, as long as satisfy the stationarity of whole anchor clamps, certainly, the hangers of anchor clamps also can be arranged on different positions as required, perhaps adopts different hangers shapes.

Certainly, the utility model is not only applicable to being installed of annular magnet workpiece, and is applicable to and other non-magnetic body annular work pieces, sheet-like workpiece in other words, is applicable to the parts of any electrophoretic coating.

The utility model generally is applicable to the electrophoresis coating technique occasion, also can be used in workpiece surface and apply and other occasions of surface-treated.
