[0003] According to international standards, aviation frames need to have an oblique groove at a specific distance from the end for label pasting. In the process of opening the oblique groove, the aviation frame needs to be fixed. The existing fixing method is mostly to fix the aviation frame directly with bolts. This fixing method requires multiple turns of the bolts when loading and unloading the aviation frame, and the position of the aviation frame needs to be adjusted multiple times before a groove can be opened at a specific position, which affects the processing efficiency of the aviation frame and has certain inconveniences in use.

DETAILED DESCRIPTION
[0023] The present invention is further described in detail below in conjunction with the embodiments:
[0024] Example 1
[0025] like Figure 1-6 As shown, the utility model provides a pneumatic tooling fixture for processing the bevel groove of the frame, including a processing table 1, a clamping mechanism 2 is fixedly connected to one side of the top of the processing table 1, an end of the top of the processing table 1 away from the clamping mechanism 2 is fixedly connected to a limiting mechanism 5, the surface of the clamping mechanism 2 is overlapped with an aviation frame 4, and the bottom of the aviation frame 4 away from the clamping mechanism 2 is overlapped with a distal support member 3, the clamping mechanism 2 includes a rotating cylinder 21, the bottom of the rotating cylinder 21 is fixedly connected to one side of the top of the processing table 1, the top of the rotating cylinder 21 is fixedly connected to a pressing plate 22, both ends of the pressing plate 22 are provided with inclined surfaces, one end of the pressing plate 22 is fitted with the surface of the aviation frame 4, the end of the top of the processing table 1 close to the rotating cylinder 21 is fixedly connected to a support frame 23, a groove 24 is opened on the top of the support frame 23, and the inner wall of the groove 24 is fitted with the surface of the aviation frame 4.
[0026] In this embodiment, different limiters are selected according to the length of the aviation frame 4 to be clamped. When the aviation frame 4 is of a longer specification, the aviation frame 4 is placed on the top of the support frame 23, so that the bottom of the aviation frame 4 fits into the groove 24, and one end of the aviation frame 4 is abutted against the second limiter 52, and then the mechanical switch 27 is turned for clamping.
[0027] Example 2
[0028] like Figure 1-6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a first fixing member 25 is fixedly connected to one end of the top of the processing table 1 close to the rotating cylinder 21, and a first limiting member 26 is fixedly connected to the top of the first fixing member 25. The top of the first limiting member 26 is provided with an inclined surface, and the top of the first limiting member 26 is in contact with the end of the pressure plate 22 away from the aviation frame 4. A mechanical switch 27 is fixedly connected to one end of the top of the processing table 1 close to the rotating cylinder 21, and two groups of clamping mechanisms 2 are provided. An inclined groove 41 is provided on the surface of the aviation frame 4, and the limiting mechanism 5 includes a second fixing member 51. The bottom of the second fixing member 51 is fixedly connected to one end of the top of the processing table 1 away from the rotating cylinder 21, and the top of the second fixing member 51 is fixedly connected to a second limiting member 52.
[0029] In this embodiment, by starting the rotating cylinder 21, under the action of the rotating cylinder 21, the pressure plate 22 is rotated ninety degrees and then moved downward until one end of the pressure plate 22 is in contact with the surface of the aviation frame 4, and the aviation frame 4 is clamped and fixed. In the process of the pressure plate 22 moving downward, the position of the pressure plate 22 is limited by the first limiting member 26 to prevent the pressure of the pressure plate 22 on the aviation frame 4 from being too great and causing damage to the aviation frame 4. In addition, the setting of the distal support member 3 can support the distal end of the aviation frame 4 to prevent the aviation frame 4 from bending due to its own gravity. After the fixation is completed, a bevel groove 41 is opened on the surface of the aviation frame 4.
[0030] Example 3
[0031] like Figure 1-6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a third fixing member 53 is fixedly connected to one end of the top of the processing table 1 close to the second fixing member 51, and a third limiting member 54 is fixedly connected to the top of the third fixing member 53, a rotating pin 55 is fixedly connected to one side of the third limiting member 54, and a rotating block 56 is rotatably connected to the middle part of the rotating pin 55, and a through groove is opened on the top of the third limiting member 54, and the width of the through groove at the top of the third limiting member 54 is greater than the width of the rotating block 56.
[0032] In this embodiment, through the mechanical switch 27, the control rotating cylinder 21 in the two groups of clamping mechanisms 2 drives the pressure plate 22 to move up and rotate ninety degrees in the opposite direction, so as to prevent the two groups of pressure plates 22 from fighting with each other, so that the aviation frame 4 can be removed. When processing a shorter aviation frame, the rotating block 56 is rotated to rotate along the rotating pin 55 to the groove at the top of the third limit member 54. During the clamping process, one end of the shorter aviation frame 4 is abutted against one side of the rotating block 56, and then clamped and fixed, so that aviation frames 4 of different lengths can be accurately positioned and clamped.
[0033] The following is a detailed description of the working principle of the pneumatic fixture for processing the bevel groove of the frame.
[0034] like Figure 1-6 As shown, when clamping, different limiting members are selected according to the length of the aviation frame 4 to be clamped. When the aviation frame 4 is of a longer specification, the aviation frame 4 is placed on the top of the support frame 23, so that the bottom of the aviation frame 4 fits with the groove 24, and one end of the aviation frame 4 is against the second limiting member 52, and then the mechanical switch 27 is turned to start the rotating cylinder 21. Under the action of the rotating cylinder 21, the pressing plate 22 is rotated ninety degrees and then moved down until one end of the pressing plate 22 fits with the surface of the aviation frame 4, and the aviation frame 4 is clamped and fixed. In the process of the pressing plate 22 moving down, the position of the pressing plate 22 is limited by the first limiting member 26 to prevent the pressing plate 22 from exerting too much pressure on the aviation frame 4 and causing damage to the aviation frame 4, and the distal support member 3 can support the far end of the aviation frame 4 to prevent the aviation frame 4 from bending due to its own gravity. After the fixation is completed, an inclined groove 41 is opened on the surface of the aviation frame 4. After the opening is completed, the control rotating cylinder 21 in the two sets of clamping mechanisms 2 drives the pressure plate 22 to move up and rotate ninety degrees in the opposite direction through the mechanical switch 27 to prevent the two sets of pressure plates 22 from fighting with each other, so that the aviation frame 4 can be removed. When processing a shorter aviation frame, rotate the rotating block 56 to rotate the rotating block 56 along the rotating pin 55 to the groove at the top of the third limit member 54. During the clamping process, one end of the shorter aviation frame 4 is abutted against one side of the rotating block 56, and then clamped and fixed, so that it can accurately position and clamp aviation frames 4 of different lengths.
[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
