Description

Technical Field

[0001] The invention relates to the field of tooling processing technology, and in particular to a hole-making tool for a cabin flange and a preparation method and a use method thereof. Background Art

[0002] Carbon fiber / resin-based composite materials have the advantages of low density, high strength, high rigidity and dimensional stability, and have been widely used in the cabin structure of rocket and missile products. In a product, the flanges of adjacent cabins are positioned by pin holes and connected by bolts, and the size and shape tolerances usually have high precision requirements. The thermal expansion coefficient of the composite cabin is extremely small, and the influence of ambient temperature changes on the hole position after the flange holes are made is extremely small. However, the pin holes and connection holes of the current machined cabin flanges are usually drilled and reamed by steel integrated tooling, and the thermal expansion coefficient of the steel tooling is much larger than that of the composite cabin. Changes in ambient temperature will cause the steel tooling to expand and contract, resulting in the difficulty of the processed cabin flange hole position to meet the high-precision design requirements. Therefore, there is an urgent need to develop a high-precision hole-making tooling for composite cabin flanges that is not affected by ambient temperature changes. Summary of the invention

[0003] In view of this, the present invention aims to create a hole-making tool for cabin flanges, and a preparation method and a use method thereof. When the ambient temperature rises or decreases by ΔT, the boss of the coordination plate moves in the avoidance opening according to the thermal expansion coefficient of the tooling material, thereby keeping the center distance from the hole-making sleeve to the mounting plate unchanged.

[0007] Furthermore, the number of the long strips, the sliding grooves, the hole-making reaming sleeves and the coordination plate components is eight.

[0009] Furthermore, the size of the boss is smaller than the size of the avoidance opening.

[0010] Furthermore, the avoidance opening is a rectangular opening, and two movable gaps are formed between the boss and the rectangular opening along the length direction of the sliding groove.

[0015] A method for preparing the hole-making tool for the cabin flange as described above comprises the following steps:

[0017] S2: Determine the effective length of the coordination plate and the distance from the first threaded through hole to the center of the circular body according to the material and thermal expansion coefficient of the mounting plate and the material and thermal expansion coefficient of the coordination plate.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0040] like Figure 1-Figure 5 As shown, a hole-making tool for cabin flange provided by an embodiment of the present invention comprises: a mounting plate and a coordination plate assembly, wherein the coordination plate assembly is fixed on the mounting plate. The mounting plate comprises a circular body 1 and long strips 2 evenly arranged on the outer circumference of the circular body 1, a sliding groove 3 is arranged on the upper surface of the long strips 2, and a through avoidance opening 4 is arranged at one end of the sliding groove 3 close to the center of the mounting plate. The number of coordination plate assemblies is equal to the number of sliding grooves, and the coordination plate assembly comprises a coordination plate 5, a boss 6, a hole-making reaming sleeve 7 and a positioning screw 8; the boss 6 is integrally formed with the coordination plate 5 and the boss 6 is arranged at one end of the coordination plate 5 close to the circular body 1, and the hole-making reaming sleeve 7 is embedded in the boss 6, which is used to assist in processing the connection hole and pin hole of the cabin flange; the other end of the coordination plate 5 is provided with a first threaded through hole 9, and the position of the sliding groove 3 corresponding to the first threaded through hole 9 is provided with a second threaded through hole 10; the positioning screw 8 is screwed with the second threaded through hole 10 through the first threaded through hole 9 to fix the coordination plate 5 in the sliding groove 3, and the boss 6 is located in the avoidance opening 4. When the mounting plate expands outward or contracts inward, the coordination plate 5 takes the positioning screw 8 as a reference point and extends toward the center of the mounting plate or shortens toward the positioning screw 8, so that the distance from the hole making sleeve 7 to the center of the mounting plate remains unchanged.

[0041] In this embodiment, a central hole is provided at the center of the circular body 1 , and weight-reducing holes are provided around the central hole. The weight-reducing holes are evenly distributed on the circular body 1 .

[0042] Therefore, by setting the avoidance opening 4, when the circular body 1 expands or contracts, the coordination plate 5 uses the positioning screw 8 as a reference point to move the boss 6 in the avoidance opening 4, keeping the distance from the hole making sleeve 7 to the center of the circular body 1 unchanged, thereby ensuring the accuracy of the connecting hole and the pin hole of the processing compartment flange.

[0043] In order to meet the processing quantity of the connection holes and pin holes of the compartment flange, in this embodiment, the number of the long plate 2, the sliding groove 3, the hole making sleeve 7 and the coordination plate 5 components is set to eight.

[0044] The number of connecting holes in the compartment flange is six, and the number of pin holes is two. Therefore, the eight hole-making sleeves 7 include six first hole-making sleeves 71 matching the connecting holes and two second hole-making sleeves 72 matching the pin holes. Each first hole-making sleeve 71 is provided with a first through hole, and each second hole-making sleeve 72 is provided with a second through hole. The two second hole-making sleeves 72 are symmetrically arranged along the radial direction of the circular body 1, and the six first hole-making sleeves 71 are symmetrically arranged on both sides of the line connecting the two second hole-making sleeves 72. The first through hole is larger than the second through hole.

[0045] In this embodiment, the first hole-making reaming sleeve 71 and the second hole-making reaming sleeve 72 are both cylindrical.

[0046] Furthermore, the size of the boss 6 is smaller than the size of the avoidance opening 4 .

[0047] Furthermore, the avoidance opening 4 is a rectangular opening, and two movement gaps are formed between the boss 6 and the rectangular opening along the length direction of the sliding groove 3. The two movement gaps are respectively larger than the length of the mounting plate undergoing outward thermal expansion and the length of the mounting plate undergoing inward cold contraction.

[0048] In this embodiment, the two moving gaps are movable displacements of the boss 6 , and the lengths of the two moving gaps are set to L1 , L1 = 5 mm. In other embodiments, the value of L1 is different depending on the size and material of the mounting plate.

[0049] Therefore, the two moving gaps are set to be larger than the length of the mounting plate's outward thermal expansion and the length of the mounting plate's inward contraction, respectively, so that they can meet the moving distance of the coordination plate 5 when the mounting plate undergoes thermal expansion or contraction.

[0050] Furthermore, the material of the mounting plate is 45# steel, the material of the coordination plate 5 is aluminum alloy, and the material of the hole making reamer sleeve 7 is hard alloy steel.

[0051] Furthermore, the effective length of the coordination plate 5 is L, and its calculation formula is:

[0052] L=(R·α1) / (α2-α1);

[0053] Among them, the distance from the hole-making reaming sleeve 7 to the center of the mounting plate is equal to the pitch circle radius R of the circular plate body, the thermal expansion coefficient of 45 steel is α1, and the thermal expansion coefficient of aluminum alloy is α2.

[0054] The present invention is combined with Figure 1-Figure 5 The hole making tool for the cabin flange provided by the present invention is described with a specific embodiment.

[0055] In this embodiment, the distance from the connecting hole and the pin hole of the cabin flange to the center of the cabin flange is equal to the pitch circle radius R of the circular body 1, that is, R=380±0.015mm. The 45# steel used in the circular body 1 has a thermal expansion coefficient of α1=11.6 (10 -6 ℃ -1 ), the coordination plate 5 adopts 6061 aluminum alloy, the thermal expansion coefficient α2=23.6 (10 -6 ℃ -1 ), the effective length of the coordination plate 5 is calculated to be L = (380×11.6) / (23.6-11.6) = 367.3333mm. The inner diameter of the 6 connection holes of the cabin flange is D1 = Φ13±0.1mm, the inner diameter of the 2 pin holes is D2 = Φ12H8 (+0.0270) mm, and the material of the hole-making hinge sleeve 7 is GCr15 hard alloy steel. For the connection holes and pin holes, standard hinge sleeves with inner diameters of D1 = Φ13±0.1mm and D2 = Φ12H8 (+0.0270) mm are used respectively. The positioning screw 8 is an alloy steel M12 standard hinge positioning screw. The distance from the positioning screw 8 to the center of the circular body 1 is R+L = 747.3333mm, and R is the pitch circle radius of the circular plate body 1.

[0056] The existing method for processing the connection holes and pin holes of the cabin flange is to use 45# steel tooling for processing. The ambient temperature of the machining workshop is usually 15~35°C, the maximum temperature difference ΔT=20°C, and the thermal expansion coefficient of 45# steel is α1=11.6 (10 -6 •℃ -1 ), ΔT represents the value of temperature change. Within this ambient temperature range, the maximum dimensional deviation of the distance from the connection hole and the pin hole to the center of the cabin flange caused by thermal expansion and contraction of the tooling is 380×11.6×10 -6 ×20=0.088mm, which will exceed the design tolerance of ±0.015mm.

[0057] Therefore, the length L1 of the two moving gaps formed between the boss 6 and the rectangular opening along the radial direction of the sliding groove 3 is set to 5 mm, which not only meets the accuracy requirement of machining the connecting holes and pin holes of the cabin flange with the hole-making tooling of the cabin flange, but also ensures that the deviation generated when the circular body 1 expands and contracts due to heat is within this moving range.

[0058] A method for preparing the above-mentioned hole-making tool for cabin flange comprises the following steps:

[0059] S1: According to the position and size of the pin hole and the connection hole of the cabin flange, determine the pitch circle radius of the mounting plate and the distance from the hole making sleeve 7 to the center of the circular body 1.

[0060] S2: Determine the effective length of the coordination plate 5 and the distance from the first threaded through hole 9 to the center of the circular body 1 according to the material and thermal expansion coefficient of the mounting plate and the material and thermal expansion coefficient of the coordination plate 5 .

[0061] S3: Firstly process the lower surface of the mounting plate, then process the outer ring of the circular body 1 and the long strip plate 2; finally process the sliding groove 3, the second threaded through hole 10 and the avoidance opening 4 for installing the coordination plate 5.

[0062] S4: The coordination plate 5 is processed and formed according to its outer dimensions so that the lower surface of the boss 6 is coplanar with the lower surface of the circular body 1, a first threaded through hole 9 is processed at one end of the coordination plate 5, and a hole-making sleeve 7 is embedded in the boss 6 at the other end of the coordination plate 5 according to the position of the pin hole or the connecting hole of the cabin flange.

[0063] S5: The positioning screw 8 fixes the coordination plate 5 in the sliding groove 3 through the first threaded through hole 9, so that the boss 6 is in the avoidance opening 4.

[0064] In this embodiment, the pitch circle radius of the mounting plate is equal to the pitch circle radius R of the circular plate main body 1. The material of the mounting plate is determined to be 45 steel, and the material of the coordination plate 5 is determined to be aluminum alloy. The thermal expansion coefficient of 45 steel is α1, and the thermal expansion coefficient of the aluminum alloy is α2. The effective length L of the coordination plate 5 is calculated to be (R·α1) / (α2-α1), and the distance from the first threaded through hole 9 and the second threaded through hole 10 to the center of the circular main body 1 is R+L, where R is the pitch circle radius of the circular plate main body 1.

[0065] A method for using the hole-making tool for a cabin flange to process connecting holes and pin holes on the cabin flange comprises the following steps:

[0066] Step 1: On the cabin flange, with the center of the cabin flange as the reference, manually mark the position lines of the pin holes and the connecting holes according to the circumferential distribution requirements of the pin holes and the connecting holes of the cabin flange and the pitch circle radius R of the circular body 1.

[0067] Step 2: Use a hand drill and a drilling jig to machine a first prefabricated hole with an inner diameter slightly smaller than the connecting hole, and machine a second prefabricated hole with an inner diameter slightly smaller than the pin hole.

[0068] In this step, the first prefabricated hole of the connection hole and the second prefabricated hole of the pin hole are firstly pre-processed, and the first prefabricated hole and the second prefabricated hole are respectively prepared for the subsequent connection hole and pin hole processing. Then, in step three, the first prefabricated hole and the second prefabricated hole will be further processed to the final required size.

[0069] Step 3: Use the hole-making tooling of the cabin flange, and on the basis of the first prefabricated hole and the second prefabricated hole, use a standard reamer to ream a connecting hole with an inner diameter of D1 and a pin hole with an inner diameter of D2, and finally obtain the connecting hole and pin hole on the cabin flange.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
