Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to a special tooling for partial silver plating of the tenon of an ultra-large titanium alloy blade. Background Technology

[0002] Because titanium alloy blades have unique properties and advantages such as light weight, high strength, high temperature and high pressure resistance, and corrosion resistance, they are widely used in aviation, aerospace and other fields to reduce the weight of aero engines. However, during operation, the blade tenon may experience failure due to fretting fatigue.

[0003] To eliminate the risk of fatigue failure of the tenon, silver plating of the tenon is currently adopted. However, due to the large size of the titanium alloy blades, whose outline dimensions are generally 440mm×216mm (length×width), and the special nature of not being able to be easily mounted, special tooling is required to perform partial silver plating of the tenon during the automated electroplating process. Utility Model Content

[0004] The purpose of this utility model is to provide a special tooling for partial silver plating of the tenon of an ultra-large titanium alloy blade, so as to meet the clamping requirements of partial silver plating of the tenon of a large titanium alloy blade.

[0005] The technical solution adopted in this utility model is: a special tooling for partial silver plating of the tenon of an ultra-large titanium alloy blade, including: a device body and multiple clamping stations located inside the device body;

[0006] The device body consists of two parallel rectangular frames and a support column that is simultaneously fixed to the outside of the symmetrical border of the two rectangular frames by welding.

[0007] The clamping station includes: two first horizontal bars welded and fixed inside a rectangular frame located at the bottom of the device body. The first horizontal bars are parallel to the short side of the rectangular frame, and the distance between the two first horizontal bars is less than the width of the blade.

[0008] A rectangular frame located on the upper part of the device body has a pair of threaded holes on its long side. Each threaded hole has a threaded rod that is threaded to it. The end of the threaded rod that extends into the rectangular frame is welded with a conductive contact head, and the end of the threaded rod that extends out of the rectangular frame is welded with a handle.

[0009] Hooks are fixedly installed on the support column;

[0010] Furthermore, the device body is made of 304 stainless steel, and the device body is covered with insulating glue of more than 3mm.

[0011] Furthermore, the conductive contact head is made of copper.

[0012] Furthermore, the clamping station also includes a second crossbar located inside a rectangular frame on the upper part of the device body. The second crossbar is parallel to the short side of the rectangular frame, with one end welded and fixed to the long side of the rectangular frame, and the other end cantilevered inside the rectangular frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] The tooling provided by this invention ensures the conductivity of the solution during the electroplating process of ultra-large titanium alloy blade parts, the compatibility of the tooling with the vehicle, and meets the requirement of partial silver plating of the tenon. Since titanium alloy blades are crucial to the overall quality of engine components, slight movement of the blade tenon during engine operation can easily lead to fatigue failure. Therefore, this tooling can effectively achieve partial silver plating of the tenon, providing a lubricating effect.

[0015] Furthermore, this tooling is reusable, ensuring consistency in the plating process during high-demand production and mitigating variable factors affecting product quality. It also boasts a long service life, and this design concept can be extended to electroplating-specific tooling for other fields such as titanium alloy blades, offering broad market prospects and economic benefits.

[0020] The technical solution adopted by this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.

[0021] This utility model provides a special tooling for partial silver plating of the tenon of an ultra-large titanium alloy blade, such as... Figure 1-3 As shown, it includes the device body and multiple clamping stations located within the device body;

[0022] The device body consists of two parallel rectangular frames 1 and a support column 2 that is simultaneously fixed to the outside of the symmetrical frame of the two rectangular frames 1 by welding.

[0023] The main body of the device is preferably made of 304 stainless steel, and the main body of the device is wrapped with more than 3mm of insulating glue to achieve insulation treatment of the entire tooling when the blade tenon is silver plated.

[0024] Located inside the device body, such as Figure 2 As shown, multiple clamping stations can be set along the long side of the rectangular frame 1. In this embodiment, [the following is an example of a clamping station]. Figure 2 Taking the two clamping stations shown as examples, the structure of the clamping stations will be explained as follows: Figure 1-2 Shown, including:

[0025] Two first horizontal bars 7 are welded and fixed inside the rectangular frame 1 at the bottom of the device body. The first horizontal bars 7 are parallel to the short side of the rectangular frame 1. The distance between the two first horizontal bars 7 is less than the width of the blade. That is, the two first horizontal bars 7 support the blade from the bottom.

[0026] A rectangular frame 1 located on the upper part of the device body has a pair of threaded holes 3 on its long side. The threaded holes 3 are preferably located in the middle of the two first crossbars 7. Each threaded hole 3 has a threaded rod 4 that is threaded to it. One end of the threaded rod 4 extends into the upper rectangular frame 1 and a conductive contact head 5 is welded to this end. The conductive contact head 5 is preferably made of copper. The other end of the threaded rod 4 extends out of the rectangular frame 1 and a fixed handle 6 is welded to this end. That is, by rotating the handle 6 located on the outside of the upper rectangular frame 1 of the device body, the distance between the conductive contact head 5 and the blade is adjusted by the cooperation of the threaded hole 3 and the threaded rod 4, so as to clamp the blade. Furthermore, by rotating the handle 6, the proximity of the conductive contact head 5 and the blade is adjusted to ensure the conductivity of the blade during the electroplating process.

[0027] Furthermore, the clamping station also includes a second crossbar 8 located inside the rectangular frame 1 on the upper part of the device body. The second crossbar 8 is parallel to the short side of the rectangular frame 1, with one end welded and fixed to the long side of the rectangular frame 1, and the other end cantilevered inside the rectangular frame 1. That is, the second crossbar 8 is used to divide each clamping station, and can also support the blades that are placed at an angle in the clamping station, further ensuring the stability of the blades during clamping.

[0028] In addition, hooks 9 are fixedly installed on the support column 2, such as welding hooks 9 to the top of the support column 2, so as to facilitate the transportation of the entire tooling using lifting equipment.

[0029] In practical use, the blade is placed between the two first crossbars 7 inside the rectangular frame 1 at the bottom of the device body. By rotating the handle 6 located on the outside of the rectangular frame 1 at the top of the device body, the blade of the conductive contact head 5 is clamped by the cooperation of the threaded hole 3 and the threaded rod 4, thus completing the clamping.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
