Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Features of various aspects of embodiments of the utility model will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention.

As shown in figure 1, which is a structural schematic diagram of a straight gear shaft part, the positions of the straight gear part and the local outer diameter of the shaft part which need to be protected are shown as X and Y in figure 1, the outer diameter of the straight gear is phi 130mm, the length of the straight gear is 9.5mm, the outer diameter of the shaft part which needs to be protected is phi 30mm, and the length of the shaft part is 19 mm. Fig. 2 is a schematic structural diagram of a straight tooth part protection tool, the tool is made of an acid-alkali-resistant blue silicone rubber material, and the color material has excellent elasticity and flexibility compared with other materials. The inner diameter of the tool in fig. 2 is 120mm in the relaxed state, and 130mm in the protection state (installation), namely: the protective tool at the straight tooth part is 10mm smaller than the straight tooth in the outer diameter in the vertical direction, and aims to enable the tool to be tightly combined with the tooth part of the part and prevent solution from immersing into a gap between the part and the tool. As shown in fig. 2, the length of the inner diameter of the protection tool is 9.5mm and is consistent with the length of the straight teeth of the part, so that the tool and the part are tightly attached; the inner parts of two sides of the tool are at an angle of 40 degrees, the outer parts of the two sides of the tool are at an angle of 64 degrees, the thickness of the tail ends of the two sides of the tool is 3mm, the thickness of the upper end of the tool is gradually increased to 5mm, and the position with the largest thickness is designed to be in a circular arc shape and used for increasing the clamping force of the two sides of the silica gel sleeve. FIG. 3 is a schematic structural view of a protection tool for the local outer diameter of a shaft part, wherein the length of the inner diameter of the protection tool is 19mm, and is consistent with the length of a part to be protected on the shaft part of a part, so that the tool is tightly attached to the part; two edge parts of the tool form an angle of 45 degrees and are used for clamping the part of the outer diameter needing to be protected; this frock thickness is 5mm, and internal diameter size is phi 25mm under the relaxed state, and internal diameter size is phi 30mm when protection state (installation), promptly: the axial region protection frock needs the little 5mm of protection position external diameter size than the part axial region in the vertical direction, and its aim at makes frock and part tooth portion closely combine, avoids solution to dip in the gap of part and frock. Fig. 4 is a schematic view of the protection tool and the part combination protection.

During the use, the operator is manual to overlap straight-tooth portion protection frock and axial region external diameter protection frock respectively in the outside that the part need protect the position to the adjustment position prevents that the position from walking partially, and the installation finishes and can to apply plating, and it weathers the part after electroplating to finish, will protect the frock manual break away from the part can, it is good to use this frock to electroplate the effect, and the face of plating is leveled, clear with non-plating face edge handing-over department, the virtual phenomenon of plating that does not have to produce because of solution leakage.
