Description

Technical Field

[0001] The utility model relates to the technical field of aircraft manufacturing, in particular to a sleeve fixing tool. Background Art

[0002] The assembled parts of the aircraft include sleeves. In order to ensure the quality of the sleeves, the sleeves need to be coated on their outer surface during production to enhance the wear resistance of the outer surface. Most of the existing sleeves are coated with electrolyte to form a coating on their surface. When coating the outer surface of the sleeve, the staff will use a hook to hang the sleeve or use a conductive metal wire to tie the sleeve to fix the sleeve, and then place the sleeve in the electrolyte, connect the cathode of the power supply to the sleeve, and place the anode of the power supply in the electrolyte, or connect it to a metal box containing the electrolyte. When the power supply is powered on, the cathode ions and anode ions in the electrolyte will be ionized. Since the sleeve is connected to the cathode, the metal cations in the electrolyte will form a coating on the surface of the sleeve. However, when the sleeve is fixed with a hanging part, after the sleeve is placed in the electrolyte, the sleeve will shake in the electrolyte, resulting in uneven coating on the surface of the sleeve, affecting the performance of the sleeve.

[0003] Some staff members will use a clamp to clamp the sleeve and put it into the electrolyte. However, when the clamp is used to clamp the sleeve, the clamp will contact the outer surface of the sleeve, and the coating cannot be formed at the contact point between the two, resulting in the outer wall of the sleeve not being completely coated, which affects the quality of the sleeve. In addition, different specifications of sleeves require different specifications of hanging parts or clamps to fix the sleeve, which is highly complicated.

[0004] Therefore, there is an urgent need for a sleeve fixing tool to solve the above technical problems. Utility Model Content

[0010] As a preferred technical solution for the sleeve fixing tool, the shape of the clamping area is a stepped cylinder with a radius decreasing from top to bottom, and the stepped cylinders with different diameters are the clamping parts.

[0030] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figure 1 and Figure 2As shown in , this embodiment provides a sleeve fixing tool for fixing a sleeve 100, and the sleeve 100 is in the shape of a tube with upper and lower openings. The sleeve fixing tool comprises a hanging member 1 and a clamping column 2, one end of the hanging member 1 is in the shape of a hook, so that the sleeve fixing tool can be hung on the side wall of the electrolyte containing box to reduce the degree of shaking of the sleeve 100 during coating. The clamping column 2 has an assembly area 21 and a clamping area 22, the assembly area 21 is fixedly connected to the other end of the hanging member 1, the clamping area 22 is located below the assembly area 21, and a clamping portion 221 is provided on the clamping area 22, and the inner wall of the sleeve 100 is fitted and fixed with the clamping portion 221 to fix the sleeve 100. On the one hand, since there is no clamped place on the outer wall of the sleeve 100, it can solve the problem in the prior art that the place where the sleeve 100 is clamped cannot be coated when the sleeve 100 is coated, so that the coating of the outer wall of the sleeve 100 is more complete and uniform. On the other hand, since the sleeve 100 is fixed in the clamping area 22 before being placed in the electrolyte for coating, the sleeve 100 can be stably placed in the electrolyte under the weight of the sleeve fixing tool, avoiding the problem of the sleeve 100 shaking during the coating process, and improving the uniformity of the coating on the outer wall of the sleeve 100. A plurality of clamping parts 221 of different specifications are provided on the clamping area 22, so that sleeves 100 of different specifications can be clamped and fixed, so that the sleeve fixing tool has higher versatility.

[0032] For example, the shape of the clamping area 22 is a stepped cylinder with a decreasing radius from top to bottom, wherein the stepped cylinders of different diameters are the clamping parts 221, so that the clamping area 22 can be processed and formed at one time, simplifying the processing technology of the sleeve fixing tooling. At the same time, the clamping column 2 can be made into an integrated structure, making the sleeve fixing tooling structure more stable, thereby clamping the sleeve 100 more stably, reducing the risk of the sleeve 100 shaking in the electrolyte.

[0033] In this embodiment, the sleeve fixing tool further includes a locking assembly 3, wherein a locking area 23 is further provided on the clamping column 2, and the locking area 23 is located below the clamping area 22. During actual assembly, the sleeve 100 is clamped between the clamping portion 221 and the locking assembly 3. In this way, the sleeve 100 can be fixed from both ends of the sleeve 100, and the sleeve 100 can be prevented from falling off from the clamping portion 221, further improving the assembly stability between the sleeve 100 and the sleeve fixing tool. Specifically, one end of the sleeve 100 is clamped and fixed by the clamping portion 221, and the other end is further clamped and fixed by the locking assembly 3.

[0034] Exemplarily, there is a continuous external thread on the locking area 23, and the locking assembly 3 includes a metal gasket 31 and a nut 32. The metal gasket 31 is sleeved in the locking area 23 and fits under the sleeve 100 to lift the sleeve 100, prevent the sleeve 100 from falling off the clamping portion 221, and improve the stability of the sleeve 100 assembly. The nut 32 has an internal thread and can be threaded with the external thread on the locking area 23 to lock the metal gasket 31 and the sleeve 100. Preferably, the shape of the metal gasket 31 is consistent with the cross-sectional shape of the sleeve 100, so that the sleeve 100 can be lifted while the material of the metal gasket 31 can be reasonably controlled. In this embodiment, the metal gasket 31 is circular.

[0035] Preferably, the metal gasket 31 and the nut 32 in the locking assembly 3 are an integrated structure, which is convenient for the staff to process the locking assembly 3, and also makes the structure of the locking assembly 3 more stable and has a longer service life. At the same time, when the staff uses the sleeve fixing tool, there is no need to separately store the metal gasket 31, which simplifies the storage of the sleeve fixing tool.

[0036] In this embodiment, the hanging member 1 and the clamping column 2 are both made of conductive materials, so that the sleeve 100 and the electrolyzed ions in the electrolyte can conduct electricity more stably, thereby improving the uniformity and efficiency of the coating of the sleeve 100. The hanging member 1 and the clamping column 2 are both made of copper. Since copper metal not only has good conductivity, but is also cheaper than other conductive metals, the production cost of the sleeve fixing tool can be guaranteed.

[0037] In this embodiment, the suspension component 1 and the clamping column 2 are connected by a bolt fastening device, wherein an assembler is provided on the assembly area 21, and the assembly hole is provided with an internal thread, the bolt fastening device is a bolt with an external thread, and a mounting hole is provided on the suspension component 1. During assembly, the staff places the suspension component 1 in the assembly position so that the assembly hole is opposite to the mounting hole, and then fixes the two with bolts.

[0038] Preferably, the suspension member 1 is in sheet form, so that the suspension member 1 has a larger contact area with the side wall of the electrolyte placement box, so that the sleeve 100 can be placed in the electrolyte more stably, and the surface coating of the sleeve 100 is uniform. The thickness of the suspension member 1 is 1mm-3mm, and the thickness of the suspension member 1 can be selected according to the use requirements, and no specific limitation is made here.

[0039] In this embodiment, the assembly steps of the sleeve 100 and the sleeve fixing tool are as follows: remove the locking assembly 3, then sleeve the sleeve 100 on the clamping area 22 and fit it with the matching clamping part 221, install the locking assembly 3, and screw the locking assembly 3 to the appropriate position, clamping the sleeve 100 between the clamping part 221 and the locking assembly 3.

[0040] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
