Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a tooling and a processing device for a special-shaped bracket. Background Art

[0002] The bracket is one of the important parts of the aircraft engine air intake. It is located below the head of the air intake and mainly serves as a supporting component.

[0003] like Figure 1 As shown, the bracket 10 structure adopts a grade II titanium alloy die forging TA15, with a length of 62mm, a width of 60mm, a height of 33mm, a wall thickness of about 1mm at the thinnest part, and a square shape as a whole. Specifically, the bracket 10 includes a body 11 and connecting pieces 12 arranged on both sides of the body 11, wherein a U-shaped notch is provided at the top of the body 11, and a through hole is provided along the length direction of the body 11, and the through hole diameter of the through hole near the top of the body 11 is larger than the through hole diameter near the bottom of the body 11. A plurality of first connecting holes 15 are provided on each side of the connecting piece 12.

[0004] At present, the previous processing scheme of the bracket 10 is to adopt Figure 2 The existing processing tool 40 shown is used for single-piece finished product processing, and the specific machining route is: wire cutting → hexagonal milling → rough milling → stress elimination → milling reference → fine milling → process table removal → burr removal. However, it is obvious that the existing processing tool only supports the body 11 from the bottom and cannot support the side of the body 11. The material of the bracket 10 is titanium alloy TA15, which has the characteristics of low density, high temperature resistance and good oxidation resistance, but the heat dissipation in the cutting area is slow, and it is easy to form high temperature in the cutting area; after processing, the parts have large rebound deformation, and the axial and radial dimensions are easy to exceed the tolerance. The existing processing tool cannot guarantee the external dimensions and form and position tolerances of the bracket 10. In addition, the single-piece trial production processing time is about 18 hours, and the processing route is complicated, the efficiency is low, and the cost is high.

[0005] Therefore, it is urgent to design a special-shaped bracket processing tooling that can ensure product quality, reduce processing time, improve production efficiency and reduce costs. Utility Model Content

The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only the directions of the reference drawings.

[0040] Embodiment 1

[0041] Combination Figure 3 and Figure 4 A tooling for processing a special-shaped bracket includes a main body 20, a base 22 and an adapter 21 arranged on the base 22.

[0042] The base 22 is provided with at least one positioning column 23, and the positioning column 23 is used to fix the bracket 10 from a first direction.

[0043] The adapter 21 defines at least one set of second connection holes 24 , and the second connection holes 24 are used to fix the bracket 10 from a second direction.

[0044] This embodiment provides a special-shaped bracket processing tooling,

[0045] Among them, Figure 1 As shown, the bracket 10 includes a body 11 and connecting pieces 12 arranged on both sides of the body 11, wherein a U-shaped notch is provided at the top of the body 11, and a through hole is provided along the length direction of the body 11, and the diameter of the through hole near the top of the body 11 is larger than the diameter of the through hole near the bottom of the body 11. The connecting piece 12 on each side is provided with a plurality of first connecting holes 15. Among them, the through hole near the bottom of the body 11 is defined as a first through hole 13, and the through hole near the top of the body 11 is defined as a second through hole 14, and the diameter of the first through hole 13 is smaller than the diameter of the second through hole 14.

[0046] Specifically, the positioning column 23 passes through the first through hole 13 to fix the bracket 10 from the first direction, and the bottom of the bracket 10 is supported by the positioning column 23. The first connecting hole 15 and the second connecting hole 24 are connected by bolts to fix the bracket 10 from the second direction, and the connecting piece 12 is attached to the outer wall of the adapter 21.

[0047] In this embodiment, the adapter 21 and the base 22 are both annular in shape. In addition, the outer diameter of the adapter 21 is smaller than the outer diameter of the base 22 .

[0048] In this embodiment, the adapter 21 and the base 22 are integrally formed, so there is no seam or connection point between the adapter 21 and the base 22, so that the special-shaped bracket processing tooling has better structural strength. In addition, since the step of assembling multiple parts is omitted, the integrally formed tooling can save production time and cost. In addition, the integral molding reduces assembly errors and can maintain higher processing accuracy and repeatability.

[0049] In this embodiment, the positioning column 23 and the base 22 are detachably connected. The detachable connection can be specifically connected in the following ways: 1. Bolt connection: Bolts and nuts are used to fix the positioning column 23 and the base 22 together, which can be easily disassembled as needed. 2. Pin connection: Pins are used to pass through the holes on the positioning column 23 and the base 22 to fix them. Tools are usually required to pull out the pins.

[0050] like Figure 4 As shown, the base 22 defines at least one positioning hole 26 . After the positioning post 23 is inserted into the positioning hole 26 , the positioning post 23 and the base 22 are detachably connected using the above-mentioned connection method.

[0051] In this embodiment, a plurality of positioning posts 23 are provided, and the plurality of positioning posts 23 are arranged along the circumference of the base 22. Figure 5 and Figure 6 According to the number of brackets 10 to be processed, six positioning posts 23 are provided. It can be understood that six positioning holes 26 are also provided.

[0052] Preferably, the six positioning posts 23 are evenly distributed along the circumference of the base 22, which helps to evenly distribute the load on the circular plate, avoid local stress concentration, and reduce deformation. In addition, the six positioning posts 23 are evenly distributed along the circumference of the base 22 to provide multi-point positioning, thereby improving the positioning accuracy and stability of the special-shaped bracket processing tooling structure.

[0053] In this embodiment, the second connection holes 24 are arranged in a matrix of M×N, where M≥1 and N≥1. Figure 3 As shown, each group of second connection holes 24 includes six holes, and the six holes are arranged in a 3×2 matrix. Figure 5 and Figure 6 According to the number of brackets 10 to be processed, six groups of second connecting holes 24 are provided.

[0054] In this embodiment, if Figure 5 As shown, the special-shaped bracket processing tool also includes a clamp body 30 connected to the main body 20. The main body 20 is provided with at least one step hole 25, and is connected to the clamp body 30 through the step hole 25. The design of the step hole 25 can provide a more precise positioning point because it allows the use of positioning pins or gaskets of different heights, thereby achieving more precise adjustment.

[0055] It can be seen from the above that the special-shaped bracket processing tooling provided in this embodiment supports both the bottom of the body 11 and the side of the body 11, thereby ensuring the outer dimensions and shape and position tolerances of the bracket 10.

[0056] like Figure 6 As shown, the method of using the utility model is as follows:

[0057] The blank is processed as a whole, and six parts are processed from each blank. The part is clamped by three jaws and one end of the part is milled. The part is then reversely tightened with a special-shaped bracket processing tooling and the other end of the part is milled. The connecting piece 12 of the part is locked on the adapter 21 with bolts, the process table is removed, and the parts are divided to obtain the bracket 10.
