Description

Technical Field

[0001] The utility model relates to the field of electrophoretic processing, and more particularly to an electrophoretic coating shielding device which is easy to fix. Background Art

[0002] During the production and processing of the shaft, it is necessary to perform electrophoresis on the outer surface of the shaft to enhance its corrosion resistance. During the electrophoresis process of the shaft, the shaft head portion needs to be shielded.

[0003] China Patent Authorization Announcement No.: CN216614888U, provides a shielding tooling for the electrophoretic paint line of the outer cylinder of the shock absorber. This patent includes a base, a shield, and an inner bore plug. A shield is provided above the base, and an inner bore plug is provided on the inner side of the shield. A sealing gap is provided between the shield and the inner bore plug. The inner bore plug includes a sleeve step and a sealing step. The sealing gap is located outside the sealing step, and a sleeve step is provided above the sealing step.

[0004] However, in the above patent, since the shielding tooling and the workpiece are directly connected, although the shielding purpose can be achieved, it is impossible to increase the squeezing force of the shielding tooling on the workpiece, resulting in the risk of electrophoretic fluid seeping into the connection between the shielding tooling and the workpiece, which is inconvenient and has certain limitations when used.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) In this solution, after the staff rotates the eccentric wheel, the shielding block No. 1 and the shielding block No. 2 can be tightened to increase the squeezing force on the shaft body, further reducing the gap between the outer wall of the shaft body and the fitting between the two shielding blocks, thereby improving the sealing performance and thus improving the shielding effect on the shaft body.

[0020] (2) In this solution, when the two shielding blocks are approaching each other, the sealing strip and the sealing block slide inside the square groove and the slot respectively, so that the intersection of the two shielding blocks on one side can be well sealed, thereby preventing the electrophoresis liquid from penetrating into the interior of the two shielding blocks from the intersection, further improving the shielding effect when the shaft is electrophoresed.

[0021] (3) In this solution, after the electrophoresis of the shaft is completed and taken out from the inside of the electrophoresis tank, the staff only needs to insert the plug rod into the outer wall of the eccentric wheel and rotate it to release the two shielding blocks from squeezing the outside of the shaft, and then the shaft and the shielding blocks can be separated. Compared with traditional masking tape and heat-resistant silicone masking, this device is reusable and more convenient to install and fix. BRIEF DESCRIPTION OF THE DRAWINGS
