When in use, the second baffle 44 rotates around the axis of the rotating shaft in the one-section groove 231 through the rotating shaft to drive the inner plate 43.

[0037] The inside of the limiting groove 6 is inserted with a partial insertion part 7, which is longitudinally inserted in the limiting groove 6 at the position of the second limiting plate 42 and the first limiting plate 22. The insertion part 7 is used to insert the limiting groove 6 in the second limiting plate 42 and the first limiting plate 22 to limit the limiting part 4 and the grinding wheel structure 2. Specifically, Figure 1As shown, the plug-in part 7 is longitudinally plugged into the position of the limiting groove 6 inside the second limiting plate 42 and the first limiting plate 22, thereby fixing the positions of the sleeve shell 21 and the rotating plate 41, and the grinding wheel part 5 is defined inside the sleeve shell 21. The inside of the sleeve shell 21 is rotatably connected with a square plate 24, the side of the square plate 24 close to the sleeve shell 21 extends through the sleeve shell 21 to the outside of the sleeve shell 21 and is fixedly connected with the output end of the driving motor, and the driving motor is used to drive the square plate 24 to rotate.

[0038] The grinding wheel part 5 is plugged into the grinding wheel structure 2, the driving motor drives part of the grinding wheel structure 2 to drive the grinding wheel part 5 to rotate around the center of the grinding wheel structure 2, and in use, an external power supply is connected, the driving motor is controlled to work through the control panel, at this time the driving motor drives the square plate 24 to rotate, and the square plate 24 synchronously drives the grinding wheel part 5 to rotate for grinding treatment.

[0039] The grinding wheel part 5 includes a grinding wheel 51 plugged into the grinding wheel structure 2, the bottom of the grinding wheel 51 extends to the outside of the grinding wheel structure 2, wherein the longitudinal section of the grinding wheel 51 is circular in design, the bottom of the grinding wheel 51 penetrates to the outside of the sleeve shell 21, and the grinding wheel 51 is used to grind aircraft parts, the center of one side of the grinding wheel structure 2 is fixed with a fixed shaft 53, the fixed shaft 53 and the grinding wheel 51 are integrally formed, the inside of the fixed shaft 53 is provided with a square groove 54, the cross sections of the square groove 54 and the square plate 24 are rectangular in design, and the square groove 54 and the square plate 24 are plugged together, wherein the four edge lengths of the square groove 54 are slightly larger than the four edge lengths of the square plate 24, so that the square plate 24 can drive the grinding wheel 51 to rotate through the square groove 54 in use.

[0040] The center of the side of the grinding wheel 51 away from the fixed shaft 53 is welded with a sleeve plate 52, and the inside of the surface of the inner plate 43 is fixed with a cylinder for sleeving the sleeve plate 52, the diameter of the cylinder is slightly smaller than the diameter of the sleeve plate 52, the sleeve plate 52 is sleeved on the cylinder on the surface of the inner plate 43, and the cylinder provides a supporting point for the other side of the grinding wheel 51, thereby facilitating the rotation of the grinding wheel 51.

[0041] The whole embodiment one achieves the effect that when using, the external power supply is connected first, and then the control panel controls the driving motor to work. At this time, the driving motor drives the square plate 24 to rotate, and the square plate 24 drives the grinding wheel 51 to rotate synchronously through the rectangularly designed square groove 54, so as to perform grinding wheel polishing processing on the parts of the aircraft. When the grinding wheel 51 needs to be replaced, the plug-in part 7 inside the limiting groove 6 is pulled out. At this time, the inner plate 43 inside the rotating groove 23 is rotated. At this time, the cylinder on one side of the inner plate 43 is separated from the sleeve plate 52. The worker can separate the square groove 54 on the other side of the grinding wheel 51 from the square plate 24. When installing, the square groove 54 is plugged in with the square plate 24 first, and then the inner plate 43 is reversely rotated. At this time, the cylinder on the surface of the inner plate 43 is plugged in with the sleeve plate 52. Then, the plug-in part 7 inside the second limiting plate 42 and the first limiting plate 22 is plugged in, and the position of the grinding wheel 51 is fixed.

[0042] Embodiment two: as shown in Figures 1-5 The plug-in part 7 includes a plug-in rod 73 partially plugged into the limiting groove 6. The cross section of the plug-in rod 73 is circularly designed, and its diameter is slightly smaller than the diameter of the limiting groove 6, which is used to plug in with the limiting groove 6 to limit the position of the limiting part 4 and the grinding wheel structure 2. The length of the plug-in rod 73 is greater than the total length of the highest point of the first limiting plate 22 and the lowest point of the second limiting plate 42. The outer surface of the top of the plug-in rod 73 is sleeved with a rubber ring 72. The rubber ring 72 is made of soft rubber, which can precisely fit the inner wall of the limiting groove 6, reducing the direct contact between the plug-in rod 73 and the limiting groove 6, thereby reducing the probability of collision between the plug-in rod 73 and the limiting groove 6 during use, to achieve the noise reduction function.

[0043] The top end of the plug-in rod 73 is fixed with a limiting strip 71. The limiting strip 71 is inversely conically designed. The cross section of the limiting strip 71 and the plug-in rod 73 is circularly designed. The diameter of the top of the limiting strip 71 is greater than the diameter of the bottom of the limiting strip 71, which is used to help the worker to pull out and plug in.

[0044] The whole embodiment two achieves the effect that when using, the plug-in rod 73 limits the fixed relationship between the inner plate 43 and the sleeve 21. The limiting strip 71 is a tool for helping the operator to pull out and plug in the plug-in rod 73 and the limiting groove 6. The rubber ring 72 is made of soft rubber, which can precisely fit the inner wall of the limiting groove 6, reducing the direct contact between the plug-in rod 73 and the limiting groove 6, thereby reducing the probability of collision between the plug-in rod 73 and the limiting groove 6 during use, to achieve the noise reduction function.

[0045] Embodiment three: as shown in Figures 1-5As shown, the embodiment also provides a grinding mechanism for part machining, which comprises a grinding machine 1 and the grinding mechanism for part machining described above. The grinding mechanism comprises a first sliding rail 12, a clamping piece 13 and a first baffle 11. The first sliding rail 12 is opened at the top of the grinding machine 1, and the first sliding rail 12 has a driving source for moving the clamping piece 13. The bottom of the clamping piece 13 is fixed with a sliding block which is inserted into the first sliding rail 12. The clamping piece 13 moves horizontally in the first sliding rail 12 relative to the grinding machine 1 through the sliding block. Specifically, the driving source pushes the clamping piece 13 to move horizontally at the top end of the grinding machine 1 in the first sliding rail 12. The first baffle 11 is located at the top of the grinding machine 1 to shield the clamping piece 13, so as to avoid the debris generated during the grinding of the aircraft parts from splashing.

[0046] Working principle: When using the grinding mechanism for part machining, an external power supply is used. First, the control panel controls the operation of the driving motor. At this time, the driving motor drives the square plate 24 to rotate. The square plate 24 synchronously drives the grinding wheel 51 to rotate through the rectangularly designed square groove 54, and the aircraft parts are subjected to grinding wheel grinding treatment. At the same time, when the grinding wheel 51 needs to be replaced, the limiting strip 71 is pulled out to pull out the plug-in rod 73 in the limiting groove 6. At this time, the inner plate 43 in the rotating groove 23 is rotated. At this time, the cylinder on one side of the inner plate 43 will be separated from the sleeve plate 52. The worker separates the square groove 54 on the other side of the grinding wheel 51 from the square plate 24. When installing, the square groove 54 is inserted into the square plate 24, and the inner plate 43 is reversely rotated. At this time, the cylinder on the surface of the inner plate 43 will be inserted into the sleeve plate 52. Then, the limiting strip 71 is pressed down to insert the plug-in rod 73 in the second limiting plate 42 and the first limiting plate 22 into the limiting groove 6, and the position of the grinding wheel 51 is fixed. The rubber ring 72 is made of soft rubber material and precisely fits the inner wall of the limiting groove 6, which reduces the direct contact between the plug-in rod 73 and the limiting groove 6, thereby reducing the probability of collision between the plug-in rod 73 and the limiting groove 6 during use, so as to realize the noise reduction function.

[0047] Finally, since the sizes of the aircraft parts are different, the driving source in the first sliding rail 12 can be controlled through the control panel to control the moving position of the clamping piece 13, and the driving source at the position of the sliding groove outside the grinding machine 1 can be controlled to control the movement of the supporting frame 3 on one side of the grinding machine 1, so as to perform grinding wheel grinding operation on aircraft parts of different specifications and sizes, and finally complete the work.

[0048] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
