Description

Technical Field

[0001] This utility model belongs to the field of aviation turbojet engine technology, and in particular relates to a double-sided protective coil installation tool for a U-shaped circuit board of aviation turbojet engine. Background Technology

[0002] In the installation of electrode holes on the U-shaped circuit board of an aero-turbojet engine, the traditional method relies on manual insertion of the silicone double-sided protective coil using sharp tools such as tweezers. This operating mode has the following significant drawbacks: Firstly, the intensity of labor and health risks: Operators need to continuously apply fine force to complete the embedding action, and prolonged work can easily cause hand muscle fatigue, joint pain, or even occupational strain. Secondly, efficiency bottleneck: the installation of individual parts takes a long time and is limited by the stability of manual operation, making it difficult for the overall assembly efficiency to meet the timeliness requirements of aircraft engine maintenance. Thirdly, there are potential quality and safety hazards: sharp tools can easily scratch the surface of the silicone protective coil, leading to a decrease in sealing performance; operational errors may damage the gold plating layer of the circuit board electrode holes or electrical components, causing poor contact; uneven manual force may cause the protective coil to be misaligned during installation, increasing the rework rate later.

[0003] There is an urgent need to develop a specialized installation tool that can achieve precise and non-destructive embedding of the protective coil through mechanical guidance and other technical means, while reducing the operation threshold and labor intensity. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1: Reference Figures 1 to 3 As shown, this utility model provides a double-sided protective coil installation tool for a U-shaped circuit board of an aviation turbojet engine, including a base 1, a plurality of columns 4 connected to the base 1, a platform 7 connected to the columns 4, a through hole opened on the platform 7, a support platform placed on the platform 7, a through hole on the support platform and the through hole being coaxially arranged, a clamping mechanism being slidably arranged in the through hole of the support platform, the clamping mechanism being used to clamp the silicone double-sided protective coil 11, a drive component being provided on the base 1, and the clamping mechanism and the drive component being in a transmission cooperation.

[0018] The support platform serves two purposes: firstly, to support the U-shaped circuit board 10, and secondly, to prevent the electrical components on the U-shaped circuit board 10 from interfering with the platform 7, which could lead to damage to the electrical components.

[0019] This utility model facilitates the installation of the silicone double-sided protective coil 11 through the cooperation of the clamping mechanism and the driving component.

[0020] Furthermore, the clamping mechanism includes a V-shaped spring 5, with clamping plates 14 connected to the opposite sides of the opening of the V-shaped spring 5, and the bottom end of the V-shaped spring 5 is connected to the drive assembly via a pull wire 18.

[0021] In this embodiment, the V-shaped spring 5 is made of elastic steel sheet, which has high connection strength and prevents it from breaking during installation.

[0022] The elastic deformation characteristics of the V-shaped spring sheet 5 are utilized in conjunction with the clamping plate 14 to clamp the silicone double-sided protective coil 11. The clamping mechanism is connected to the drive assembly via the pull wire 18, which facilitates the control of the clamping mechanism's operation through the drive assembly.

[0023] Furthermore, each of the two clamping plates 14 is connected to a claw 13, which is arranged opposite to each other and located at the opening of the V-shaped spring piece 5.

[0024] The design of the claw 13 further enhances the clamping effect of the clamping mechanism on the silicone double-sided coil guard 11, ensuring that the silicone double-sided coil guard 11 will not loosen or fall off during installation. It should be noted that the rubber coating treatment on the surface of the claw 13 will cause scratches to the silicone double-sided coil guard 11.

[0025] Furthermore, the support platform includes multiple pads 8, which are stacked together.

[0026] By stacking multiple shims 8, the height of the support platform can be adjusted according to actual needs to accommodate the installation requirements of U-shaped circuit boards and silicone double-sided protective coils 11 of different specifications of aviation turbojet engines. After the installation of one silicone double-sided protective coil 11 is completed, multiple shims 8 can be separated from the platform 7, so that the V-shaped spring 5 can pass through the holes of multiple shims 8 again to re-clamp and fix another silicone double-sided protective coil 11.

[0027] Furthermore, multiple gaskets 8 are nested with guide tubes 6. The top end of the guide tube 6 is provided with a tapered opening 9, which is flush with the upper surface of the uppermost gasket 8. The bottom end of the guide tube 6 passes through a through hole.

[0028] The guide tube 6 and its tapered opening 9 at the top can serve as a guide, enabling the silicone double-sided protective coil 11 to accurately enter the designated position during installation, thereby improving the accuracy and efficiency of installation.

[0029] Furthermore, the drive assembly includes a bracket 15 vertically fixed to the base 1, with one end of a pressure rod 2 hinged to the bracket 15. The pressure rod 2 is connected to the bottom end of a V-shaped spring 5 via a pull wire 18.

[0030] In this embodiment, the pull wire 18 is made of steel wire.

[0031] By manually operating the pressure rod 2, the V-shaped spring 5 can be easily deformed by pulling the wire 18 through the lever principle, thereby controlling the clamping and releasing actions of the clamping mechanism. The operation is simple and labor-saving.

[0032] Furthermore, two limiting plates 3 are vertically connected to the base 1, and the pressure rod 2 is slidably limited between the two limiting plates 3.

[0033] The two limiting plates 3 limit the pressure rod 2, ensuring that the pressure rod 2 can only move within the specified range during operation, making the operation of the drive component more stable and reliable, and avoiding lateral swaying when the pressure rod 2 is pressed down, which could lead to installation failure.

[0034] The double-sided protective coil installation tool for the U-shaped circuit board of the aviation turbojet engine provided by this utility model works as follows: In use, the upper electrode circular hole 12 of the U-shaped circuit board 10 is aligned with the center hole of the guide tube 6. The U-shaped circuit board 10 is supported by the pad 8. The V-shaped spring piece 5, which has already passed through the guide tube 6, is passed through the electrode circular hole 12. The bottom flange of the silicone double-sided protective coil 11 is clamped onto the claws 13 on the two clamping plates 14. Then, the pressure rod 2 is pressed down to make it rotate. The rotating pressure rod 2 pulls the V-shaped spring piece 5 downward along the guide tube 6 through the pull wire 18, so that the two clamping plates 14 on the V-shaped spring piece 5 are further closed, further clamping the silicone double-sided protective coil 11. At the same time, the bottom flange of the silicone double-sided protective coil 11 is stretched and passes through the electrode circular hole 12. As the bottom flange of the silicone double-sided protective coil 11 is gradually stretched down and finally released from the constraint of the claws 13, it returns to its original position and adheres to the lower surface of the U-shaped circuit board 10, completing the installation.

[0035] Example 2: Reference Figure 4 The difference between this embodiment and the first embodiment is that the driving component is a telescopic cylinder 16 fixedly connected to the base 1, and the output end of the telescopic cylinder 16 is rigidly connected to the V-shaped spring 5 through the pull wire 18.

[0036] In this embodiment, the telescopic cylinder 16 uses a cylinder to replace manual labor, thereby improving installation efficiency.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
