[0023] like Figure 1-4 As shown, an embodiment of this utility model provides a UAV arm processing fixture, including a mounting plate 2, a base 1 mounted below the mounting plate 2, and support columns 3 vertically fixed at the four corners between the base 1 and the mounting plate 2. A through hole 4 is drilled at the top of the mounting plate 2, and a fixing component 5 for auxiliary arm fixing is installed at the top of the mounting plate 2 corresponding to the through hole 4. A plurality of through holes 4 are provided, and the plurality of through holes 4 are arranged in a rectangular array at the top of the mounting plate 2. The through holes 4 vertically penetrate the mounting plate 2. The through holes 4 arranged in a rectangular array and the detachable fixing component 5 form a dynamic adaptation mechanism, which effectively solves the size compatibility problem of processing UAV arms of various specifications.

[0024] The aforementioned fixing component 5 includes a protruding seat 6, with a hinge seat protruding from the top of the protruding seat 6. A support rod 8 and an extension rod 9 are symmetrically hinged at the hinge seat. The support rod 8 and the extension rod 9 are fixedly connected by a handle 7. An installation block 10 is sleeved on the end of the extension rod 9 away from the support rod 8. The installation block 10 has a U-shaped plate structure, and there are two installation blocks 10 symmetrically arranged. A pressing seat 11 for auxiliary arm pressing is installed at the bottom of the installation block 10. A screw 111 is vertically fixed at the top of the pressing seat 11. The screw 111 is installed through the installation block 10, and a nut 112 is threaded onto the screw 111. The nut 112 presses against the top of the installation block 10.

[0025] By using the fixed component 5, which employs a linkage structure of support rod 8 and extension rod 9, the synchronous pressing action of the pressing seat 11 can be achieved through a single-point operation of handle 7, simplifying the operation process and improving positioning efficiency. Through the screw 111 and nut 112 cooperation structure of the pressing seat 11, the pressing position can be finely adjusted, which can adapt to the processing requirements of different specifications of machine arm shapes, avoiding the problem of limited applicability caused by the fixed size of traditional fixtures.

[0026] The protruding seat 6 is symmetrically equipped with positioning components 12, which are fixed to the through hole 4. The positioning components 12 include a positioning cylinder 13 fixed on the protruding seat 6. The positioning cylinder 13 has a pressure chamber inside, and a pressure seat 15 is slidably arranged in the pressure chamber. The bottom of the pressure seat 15 is conical. Positioning balls 14 press against the outer edge of the pressure seat 15. A pull ring is fixed at the top of the sealing seat 161. A trumpet-shaped extrusion chamber 131 is opened on the side of the positioning cylinder 13. Positioning balls 14 are slidably arranged in the extrusion chamber 131. A slide rod 16 is vertically fixed at the top of the pressure seat 15. The sealing seat 161 is fixed at the top of the slide rod 16. A pressure spring 17 is installed in the pressure chamber to assist the pressure seat 15 in pressing.

[0027] By using the positioning component 12, the horn-shaped extrusion cavity 131 of the positioning component 12 and the rolling engagement design of the positioning ball 14 transform the traditional sliding friction into rolling friction, significantly reducing the frictional resistance during the positioning process. At the same time, the continuous top pressure provided by the top pressure spring 17 ensures that the positioning ball 14 and the inner wall of the through hole 4 always maintain close contact, effectively preventing displacement or vibration during the machining process of the machine arm. The sealing structure of the top pressure cavity inside the positioning cylinder 13, combined with the pull ring design on the top of the sealing seat 161, not only ensures the working stability of the top pressure spring 17, but also facilitates quick disassembly and maintenance.

[0028] The working principle of the technical solution provided by this utility model is as follows: The mounting plate 2 serves as the main support structure, and the rectangular array of through holes 4 drilled on its top penetrates the thickness direction of the mounting plate 2, which can reduce the overall weight and facilitate real-time observation of the fixed status of the machine arm during processing. The hinged support rod 8 and extension rod 9 form a linkage mechanism. The operating handle 7 can synchronously control the swing angle of the two rods, so that the mounting block 10 at the end of the extension rod 9 drives the pressing seat 11 to achieve a vertical pressing action. The pressing seat 11 is inserted into the bottom of the mounting block 10 through the screw 111. With the threaded locking structure of the nut 112, the extension length of the pressing seat 11 can be finely adjusted to adapt to machine arms of different diameters.

[0029] The positioning components 12 are symmetrically arranged on both sides of the protruding seat 6. The positioning cylinder 13 has a top pressure cavity. The top pressure spring 17 pushes the top pressure seat 15 to move downward. The conical structure at the bottom of the top pressure seat 15 squeezes the positioning ball 14 to expand outward along the trumpet-shaped squeezing cavity 131, and finally forms a three-point positioning fit with the bottom inner wall of the through hole 4, and fixes the fixing component 5 in the corresponding position, thereby adapting to the fixing requirements of different sized arms.

[0030] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
