Description

Technical Field

[0001] The utility model belongs to the technical field of manual glue removal tools, and more specifically relates to a glue removal tool for a threaded hole of a servo valve housing. Background Art

[0002] When repairing the servo valve housing of a certain type of aircraft, it is necessary to clean the residual anaerobic thread glue in the housing threads. Currently, it is removed bit by bit with pointed tools such as dental probes, which is difficult to ensure clean removal and is easy to damage the threads, resulting in low work efficiency. Since the threaded hole of the servo valve housing is divided into an outer threaded part and an inner through hole, it is easy to produce excess glue blocks during the cleaning process, which pollutes the internal oil circuit of the housing, causing oil contamination in subsequent production, delaying the aircraft maintenance period or aircraft failures, and other quality problems, causing safety hazards. Utility Model Content

[0003] The utility model aims to provide a glue removal tool for a threaded hole of a servo valve housing, so as to solve the technical problems of low glue removal efficiency and potential safety hazards in the prior art.

[0013] In combination with the above technical solution, in a possible implementation, at least one blade groove is formed on the inner end of the connector along the axial direction of its outer circumferential surface.

[0014] In combination with the above technical solution, in a possible implementation, there are two blade grooves, and the two blade grooves are symmetrically arranged about the axis of the connector.

[0015] In combination with the above technical solution, in a possible implementation, the inner wall of the blade groove is arc-shaped.

[0016] In combination with the above technical solution, in a possible implementation manner, the force applying member and the connector are detachably connected.

[0017] In combination with the above technical solution, in a possible implementation manner, one of the force-applying member and the plug-in member is provided with a connecting hole, and the other is provided with a connecting block that is plugged in and cooperates with the connecting hole.

[0018] The beneficial effect of a glue removal tool for the threaded hole of a servo valve housing provided by the utility model is that: compared with the prior art, the utility model first seals the through hole inside the threaded hole by a sealing piece, and then screws the plug-in piece into the threaded hole by a force-applying piece, and at the same time, the spiral cutting edge spirally cuts off the residual thread glue in the threaded hole, and after the cutting is completed, the plug-in piece is reversed by the force-applying piece to make it detach from the threaded hole, the thread glue cut off in the threaded hole can be poured out, and then the sealing piece can be taken out, which not only improves the glue removal efficiency, but also can prevent glue blocks from entering the through hole to pollute the internal oil circuit of the housing, thereby reducing safety hazards.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the present application, not all of the embodiments, and the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] It should be further explained that the drawings and implementation modes of the present invention mainly describe the concept of the present invention. On the basis of this concept, some specific forms and settings of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above-mentioned specific forms and settings in a well-known manner.

[0028] The following is a description of a glue removal tool for a threaded hole of a servo valve housing provided by the utility model.

[0029] like Figure 1 and Figure 2 As shown, one embodiment of the utility model provides a tool for removing glue from a threaded hole of a servo valve housing, comprising a connector 1, a spiral cutting edge 2, a force-applying member 3 and a sealing member 4; the connector 1 is used to be inserted into the threaded hole; the spiral cutting edge 2 is arranged on the connector 1, and the spiral cutting edge 2 is used to scrape off residual thread glue in the threaded hole; the force-applying member 3 is arranged at a position where the connector 1 is located outside the threaded hole, and the force-applying member 3 is used to drive the connector 1 to rotate; the sealing member 4 is used to be inserted into the inner end of the threaded hole and seal the inner through hole of the threaded hole.

[0030] Specifically, in this embodiment, the connector 1 is a cylindrical structure, and the length and diameter of the connector 1 can be matched and set according to threaded holes of different specifications.

[0031] The present embodiment provides a glue removal tool for the threaded hole of the servo valve housing. Compared with the prior art, the through hole inside the threaded hole is first sealed by the sealing member 4, and then the plug-in member 1 is screwed into the threaded hole by the force-applying member 3. At the same time, the spiral cutting edge 2 spirally cuts off the residual thread glue in the threaded hole. After the cutting is completed, the plug-in member 1 is reversed by the force-applying member 3 to make it detach from the threaded hole, and the thread glue cut off in the threaded hole can be poured out, and then the sealing member 4 can be taken out. This not only improves the glue removal efficiency, but also prevents the glue block from entering the through hole to pollute the internal oil circuit of the housing, thereby reducing safety hazards.

[0032] like Figure 1 and Figure 3 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0033] The blocking member 4 includes a positioning member 41 and a shielding member 42; the positioning member 41 is used to be inserted into the inner through hole of the threaded hole, the shielding member 42 is located at the inner end of the threaded hole and connected to the positioning member 41, and the shielding member 42 blocks the inner through hole of the threaded hole.

[0034] Specifically, in this embodiment, the positioning member 41 is a cylindrical structure matching the through hole inside the threaded hole, the shielding member 42 is a plate-like structure, and the inner diameter of the threaded hole itself is larger than the inner diameter of the through hole inside the threaded hole.

[0035] Before removing the glue, the blocking member 4 is first inserted into the threaded hole, so that the positioning member 41 is automatically inserted into the inner through hole of the threaded hole by gravity, and the shielding member 42 automatically blocks the through hole, which improves the convenience of operation. After the glue is removed, the housing is turned over so that the threaded hole opening is downward, and the positioning member 41 and the shielding member 42 are separated from the threaded hole and the through hole by their own gravity.

[0036] Furthermore, the shielding member 42 is provided with a thread groove 411 extending into the positioning member 41. If the blocking member 4 is stuck in the inner end of the threaded hole and cannot fall out by its own gravity, other tools with threaded rods can be screwed into the thread groove 411 to pull out the blocking member 4.

[0037] like Figure 2 and Figure 4 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0038] At least one blade groove 11 is formed at the inner end of the connector 1 along the axial direction of its outer peripheral surface.

[0039] Furthermore, there are two blade grooves 11 , and the two blade grooves 11 are symmetrically arranged about the axis of the connector 1 .

[0040] Furthermore, the inner wall of the blade groove 11 is arc-shaped.

[0041] The blade groove 11 can accommodate the rubber blocks scraped off during the glue removal process, thereby improving the smoothness of the rotation of the connector 1. The arc-shaped inner wall of the blade groove 11 can make it easier to discharge and clean the rubber blocks.

[0042] like Figure 1 As shown, the utility model provides a specific implementation method based on the above implementation method as follows:

[0043] The force-applying member 3 is detachably connected to the plug-in connector 1. One of the force-applying member 3 and the plug-in connector 1 is provided with a connecting hole 5, and the other is provided with a connecting block 6 that is plugged in with the connecting hole 5.

[0044] Specifically, in this embodiment, the force member 3 is a columnar structure, the connection hole 5 and the connection block 6 are both rectangular or other non-cylindrical, the connection hole 5 is opened on the force member 3, and the connection block 6 is fixed to the outer end of the connector 1.

[0045] The size of the connecting block 6 on the connector 1 with different lengths and diameters provided for different types of threaded holes remains unchanged, that is, one force-applying member 3 can be applied to connectors 1 of various types, thereby improving the convenience of use of the tooling.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0047] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
