[0022] Example
[0023] like Figs. 1-2 As shown, a fixing support includes a fixing base 1, which is a cylindrical structure. The top diameter of the fixing base 1 is smaller than the bottom diameter. A plurality of first supporting ears 2 and a plurality of second supporting ears 3 are fixed on the fixing base 1. The first supporting ears 2 are vertically arranged on the outer surface of the fixing base 1, and the second supporting ears 3 are horizontally arranged at the bottom of the outer surface of the fixing base 1. The first supporting ears 2 and the second supporting ears 3 are arranged crosswise. Bolt holes are opened on the first supporting ears 2 and the second supporting ears 3. A plurality of sliding fixing devices are provided on the fixing base 1. The sliding fixing devices are arranged above the second supporting ears 3, and a fixing assembly is provided on the two sliding fixing devices arranged opposite to each other.
[0024] It is worth noting that the fixed seat 1 is sleeved on the outside of the aerospace part to fix the aerospace part that needs to be processed, which facilitates processing. The fixed seat 1 is fixed to the processing tooling by the first support ear 2 and the second support ear 3, and the part is fixed on the fixed seat 1 by the sliding fixing device. The sliding fixing assembly can be adjusted and aligned according to the position of the mounting hole on the part. The sliding fixing assembly adjusted to the appropriate position is fixed by the fixing assembly to prevent the part from sliding relative to the fixed seat 1.
[0025] In particular, the first lug 2 is arranged vertically, and the second lug 3 is arranged horizontally. When the fixing base 1 is fixed on the processing tooling, the two different arrangements can meet different fixing methods.
[0026] In some feasible embodiments, the bottom of the first ear 2 is flush with the bottom of the fixing base 1 , so that when the fixing base 1 is fixed on a tooling on a horizontal plane, the first ear 2 does not interfere with the fixation of the fixing base 1 .
[0027] In some possible embodiments, the sliding fixing device is a sliding block 5, a square hole 4 is formed on the fixing base 1, the sliding block 5 is slidably arranged in the square hole 4, a bolt hole is formed on the sliding block 5, the sliding block 5 can slide up and down in the square hole 4, so that the bolt hole on the sliding block 5 can be aligned with a mounting hole on a part, and the part can be fixed on the fixing base 1 after bolts are sequentially threaded through the bolt hole and the mounting hole.
[0028] In some possible embodiments, the square hole 4 is provided with sliding grooves on the left and right sides matched with the sliding block 5, since the fixing base 1 is a variable-diameter structure, the square hole 4 has an upper narrow and lower wide structure, the sliding grooves are embeddedly arranged on the side walls of the square hole 4, and the distance between the sliding grooves and the side walls of the square hole 4 gradually increases from the bottom to the top.
[0029] In some possible embodiments, the fixing assembly includes two fixing grooves 7 and fixing bolts 8, the fixing grooves 7 are arranged on the left and right sides of the square hole 4, the sliding block 5 is provided with holes matched with the fixing bolts 8 on the left and right sides, and the fixing bolts 8 are threadedly connected through the fixing grooves 7 and the holes on the left and right sides of the sliding block 5. When the sliding block 5 slides to a proper position, the fixing bolts 8 are rotated, since the sliding block 5 cannot be rotated, the sliding block 5 will move along the radial direction of the fixing bolts 8, so that the sliding block 5 is pressed against the fixing base 1, and the fixing effect is achieved.
[0030] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the specification is described in this way only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand. Thus, the embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description. The scope of the present disclosure is defined by the appended claims.
