Description

Technical Field

[0001] The utility model relates to the technical field of surface treatment tooling, in particular to an anodizing shielding tooling. Background Art

[0002] At present, during the anodizing process of some areas of aluminum alloy products, the remaining areas need to be masked. For example, in the processing of workpieces such as Showerhead, the outer side walls need to be oxidized and the remaining parts need to be masked. However, when masking by brushing ink or glue, it is easy to cause problems such as poor coating uniformity, the need to dry after painting, incomplete masking and easy leakage, and there are no threaded holes on the upper and lower planes of the workpiece product, which makes it inconvenient to set other masking parts. Utility Model Content

[0003] The utility model aims to provide an anodizing shielding tool, which can conveniently shield products without opening threaded holes on the upper and lower sides, is convenient for moving into the oxidation station, and ensures the shielding effect.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] An anodizing masking tool comprises an upper masking jig and a lower masking jig. A groove matching the bottom of a product is provided on the upper side of the lower masking jig. A sealing gasket is arranged in the groove, and the bottom of the product is placed on the sealing gasket. The upper masking jig and the lower masking jig are connected by connecting screws and are respectively clamped on the upper and lower sides of the product. The upper side of the upper masking jig is connected to the upper screws, and the side wall of the workpiece is connected to the side screws. The upper screws are used for conducting electricity and are connected to the side screws through wires to conduct conductive oxidation on the side wall of the product.

[0006] By adopting the above technical solution, the sealing gasket plays a sealing role, so that the product and the lower shielding jig are more closely fitted, ensuring that no liquid medicine enters, thereby improving the shielding effect; the upper shielding jig and the lower shielding jig are connected by connecting screws, and are clamped on the upper and lower sides of the product respectively, so that it is convenient to move the entire jig into the oxidation station for oxidation, and there is no need to open threaded holes on the upper and lower sides of the workpiece; and because there is a layer of masking tape or glue between the upper shielding jig and the product, there is no conductivity between them. In order to make the workpiece conductive stably, an upper screw is connected to the upper side of the upper shielding jig, and a side screw is connected to the side wall of the workpiece near one of the upper screws. The upper screw is used for conductivity and is connected to the side screw through a wire to conduct conductive oxidation on the side wall of the product, so as to finally achieve anodizing at the side wall.

[0007] Furthermore, the groove on the lower shielding jig shields the outside of the R corner of the bottom of the workpiece.

[0008] By adopting the above technical solution, since the bottom R corner of the product is not oxidized, normal masking cannot guarantee the masking of the bottom R corner part, and this oxidation does not seal the hole, and it is difficult to trim after oxidation, so the bottom R corner of the product is masked by using the groove part on the lower masking jig.

[0009] Furthermore, the sealing pad is a silicone pad.

[0010] By adopting the above technical solution, the product and the lower shielding jig are more closely fitted, thereby improving the shielding effect.

[0011] Furthermore, the silicone pad is fixed in the groove on the lower shielding jig by double-sided tape.

[0012] By adopting the above technical solution, the replacement of the silicone pad is convenient.

[0013] Furthermore, the conductive wire is an aluminum wire, which is wound between the upper screw and the side screw.

[0014] By adopting the above technical solution, the disassembly and assembly of the wires is facilitated.

[0015] Furthermore, the connecting screws, upper screws and side screws are all titanium screws.

[0016] By adopting the above technical solution, the conductivity of titanium alloy is better than that of ordinary steel screws, it can transmit current more efficiently, and it has higher corrosion resistance and wear resistance.

[0017] Furthermore, the side wall of the product is oxidized, and the remaining parts are provided with a layer of tape.

[0018] By adopting the above technical solution, the bare aluminum area of ​​the product is masked with tape, so that the entire side wall is oxidized, while the remaining areas are masked; and because the upper side of the upper masking jig is connected to the upper screws, and the side screws are connected to the side wall of the workpiece, the upper screws are used for conduction and are connected to the side screws through wires, so the tape layer will not affect the conductive oxidation of the product side wall.

[0019] Furthermore, the tape layer is a high temperature resistant tape.

[0020] By adopting the above technical solution, the deformation and failure of the tape layer at high temperature can be avoided, and the stability of the shielding process during the oxidation process is improved.

[0021] In summary, the utility model has the following beneficial effects:

[0022] The sealing gasket plays a sealing role, making the product fit more closely with the lower shielding jig, ensuring that no liquid medicine enters, and improving the shielding effect; the upper shielding jig and the lower shielding jig are connected by connecting screws, which are clamped on the upper and lower sides of the product respectively, making it convenient to move the whole into the oxidation station for oxidation, and there is no need to open threaded holes on the upper and lower sides of the workpiece;

[0023] Since the bottom R corner of the product is not oxidized, normal masking cannot guarantee the masking of the bottom R corner part, and this oxidation does not seal the hole, and it is difficult to trim after oxidation, so the bottom R corner of the product is masked by using the groove part on the lower masking jig;

[0024] The sealing pad is a silicone pad, which makes the product fit better with the lower shielding jig. The side wall of the product is oxidized, and a layer of tape is provided on the outside of the remaining parts to improve the shielding effect. The wire is an aluminum wire, which is wound between the upper screw and the side screw to facilitate the disassembly and assembly of the wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, and this embodiment does not constitute a limitation of the utility model. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] An anodizing masking tool, such as Figure 1 As shown, it comprises an upper shielding jig 1 and a lower shielding jig 2. A groove 21 adapted to the bottom of the product is provided on the upper side of the lower shielding jig 2. A sealing gasket 22 is provided in the groove 21. The bottom of the product is placed on the sealing gasket 22. The sealing gasket 22 has a sealing effect, so that the product and the lower shielding jig 2 fit better, ensuring that no liquid medicine enters, thereby improving the shielding effect.

[0031] The sealing pad 22 is a silicone pad, which mainly plays a shielding effect. The silicone pad is fixed in the groove 21 on the lower shielding jig 2 by double-sided tape or other means, so as to facilitate the replacement of the silicone pad.

[0032] like Figure 1 As shown, since the bottom R corner of the product is not oxidized, normal masking cannot guarantee the masking of the bottom R corner part, and it is difficult to trim after oxidation, so the groove 21 on the lower masking jig 2 is masked outside the bottom R corner of the workpiece to mask the bottom R corner of the product;

[0033] like Figure 1 and Figure 2 As shown, since there are no threaded holes on the upper and lower planes of the product, the lower shielding jig 2 cannot be fixed to the product. Therefore, an upper shielding jig 1 is also provided in the anodizing masking tooling. The upper shielding jig 1 and the lower shielding jig 2 are connected by connecting screws 3, and are respectively clamped on the upper and lower sides of the product. The upper shielding jig 1 and the lower shielding jig 2 are connected by connecting screws 3, so that the two are respectively clamped on the upper and lower sides of the product, which is convenient for the overall movement into the oxidation station for oxidation, and there is no need to open threaded holes on the upper and lower sides of the workpiece for fixing.

[0034] like Figure 1 As shown, the side wall of the product is oxidized, and a layer of tape layer 6 is provided on the outside of the remaining parts. The tape layer 6 is a high-temperature resistant tape to improve the shielding during the oxidation process; the bare aluminum area of ​​the product is shielded with tape, so that the entire side wall is oxidized, while the remaining areas are shielded; specifically, the product includes an upper disk body and a lower disk body, the outer diameter of the upper disk body is larger than that of the lower disk body, and the tape layer 6 is adhered to the upper and lower side surfaces of the upper disk body and the lower side surface of the lower disk body.

[0035] like Figure 1 and Figure 2 As shown, because there is a layer of high temperature resistant tape between the upper shielding jig 1 and the product, there is no electricity between them. In order to make the workpiece as a whole conduct electricity through the jig, the upper side of the upper shielding jig 1 is connected with an upper screw 4, and a side screw 5 is connected to the side wall of the workpiece near one of the upper screws 4. The upper screw 4 is used for conducting electricity and is connected to the side screw 5 through a wire to conduct electricity and oxidize the side wall of the product, so as to finally realize the anodizing of the side wall.

[0036] Specifically, there are two upper screws 4 with a size of M8, which are respectively connected to the opposite sides of the upper shielding jig 1, and are used to be hung on a mobile lifting mechanism and other devices, moved and sunk into the anodizing area for oxidation, and there are 8 connecting screws 3 with a size of M8*76, and there is one side screw 5 with a size of M8.

[0037] like Figure 2As shown, the conductor is an aluminum wire, which is wound between the upper screw 4 and the side screw 5 to facilitate the disassembly and assembly of the conductor; the connecting screw 3, the upper screw 4 and the side screw 5 are all titanium screws, which can transmit current more effectively and have higher corrosion resistance and wear resistance.

[0039] Step S1, masking the bare aluminum area of ​​the product with high-temperature green tape, so that the entire side wall is oxidized and the remaining area is masked;

[0040] Step S2, cutting the silicone pad into a suitable size, and fixing it inside the groove 21 of the lower shielding jig 2 with double-sided tape (or other fixing tools);

[0041] The silicone pad has a sealing effect, so that the product and the lower shielding fixture 2 fit better, ensuring that no liquid medicine enters, thereby improving the shielding effect;

[0042] Step S3, placing the bottom of the product on the silicone pad, and pressing the upper shielding jig 1 on top of it;

[0043] Step S4, the upper shielding jig 1 and the lower shielding jig 2 are fixed with M8 titanium screws (connecting screws 3) on all sides;

[0044] The upper shielding jig 1 and the lower shielding jig 2 are connected by connecting screws 3, and are clamped on the upper and lower sides of the product respectively, so as to facilitate the overall movement of the product into the oxidation station for oxidation, and there is no need to open threaded holes on the upper and lower sides of the workpiece;

[0045] Step S5, a titanium screw (side screw 5) is installed on the side wall thread, and the titanium screw (upper screw 4) hanging from the top is fixed with aluminum wire for conducting electricity.
