Description

Technical Field

[0001] The present application relates to the technical field of tooling structures, and in particular to a deformation repair clamping tool and a clamping method. Background Art

[0002] Aircraft thin-walled frame beam parts often deform after processing due to factors such as large material removal, thin wall thickness or insufficient strength of the parts themselves, resulting in quality failures or even scrap. For large-sized thin-walled frame beam parts, or parts with high shape tolerance requirements such as flatness, contour, straightness, etc., whether they are made of aluminum alloy, titanium alloy or steel, the distortion or warping of the parts is often eliminated through the process route of roughing, aging, deformation repair, semi-finishing, deformation repair, and finishing. Sometimes, after the rough machining stage is completed, vibration aging or heat aging stress relief is even considered to release the machined stress as much as possible. The deformation of the rough-machined parts is basically eliminated after the subsequent process route to meet the final quality status of the parts.

[0003] There are many methods for the two "deformation repairs" in this route. The two most commonly used methods in the prior art are: first, after the parts have adjusted their allowance, use adhesive to bond the process boss to the tooling to flatten the process boss and the part profile; second, in the gap below the process boss (deformation), first use a gasket to fill the gap, then adjust the equalized allowance, and then reversely tighten the screws to flatten the process boss and the part profile. For the adhesive method to repair deformation, the difficulty lies in adjusting the part allowance and applying glue. In order to make the allowance of each position of the part uniform, it is necessary to check the table several times on site. After determining that the allowance is appropriate, glue is applied to bond the process boss to the tooling, and the flattening can be performed only after the glue is completely bonded. For frame beam parts, there are relatively many process bosses. The task of adjusting the height of each process boss and evenly dividing the part allowance often requires operators with higher skills to complete. In addition, applying glue is time-consuming, labor-intensive, and not environmentally friendly. It is also troublesome to remove the solid glue after subsequent processing. For the gap below the process boss, first use a gasket to fill the gap, then adjust the equalization margin, and then tighten the screws in reverse after the boss is filled to flatten the process boss and the part profile. The task of adjusting the height of each process boss and evenly dividing the part margin also requires operators with higher skills to complete, and the operator also needs to have a high sense of responsibility to prevent false padding. If the gap is not filled with a gasket, when the screw is locked, the process boss is pulled back by the screw. After the profile is repaired, the screw is loosened to cause the part to rebound, causing new clamping deformation. For such easily deformed frame beam parts, the process of repairing deformation is difficult to clamp, takes a long time to clamp, and has a short milling time, which often becomes the problem of out-of-control part cost. Only by significantly reducing the clamping time can the occupied time of the machine tool be released, and the machine tool can be kept in the milling state as much as possible to improve the processing efficiency. Summary of the invention

[0004] The purpose of the present application is to provide a deformation repair clamping tool, which can be quickly clamped by a four-point support method, greatly reducing the difficulty of clamping and adjustment of the operator, and reducing the skill requirements of the operator. That is, during the deformation repair process of the frame beam parts, due to the structural design of the tool, only one or two process boss gaps need to be adjusted, which greatly reduces the clamping workload. When the two corner bosses need to be adjusted, only equal-thick gaskets need to be used to fill them, and there is no need to perform repeated meter verification, which reduces the skill level requirements of the operator, reduces the difficulty and time of deformation repair, and improves product quality and the efficiency of deformation repair.

[0008] A support column, comprising a first column, a second column, a third column and a fourth column, wherein the first column, the second column, the third column and the fourth column are arranged in a quadrilateral on the horizontal plane;

[0009] When in a first working condition, one end of the frame beam part is laid on the first column, and in response to the gap between the other end of the frame beam part and the third column being less than a preset gap, the gasket is arranged on the third column; when in a second working condition, one end of the frame beam part is laid on the first column, and in response to the gap between the other end of the frame beam part and the third column being greater than or equal to a preset gap, a plurality of gaskets are respectively arranged on the third column and the first column, and the third column and the first column are diagonally arranged.

[0010] In some embodiments of the present application, the first column, the second column, the third column and the fourth column all include a column portion and an abutment portion, the abutment portion is detachably connected to the column portion by bolts, and one end of the abutment portion is used to abut the frame beam part, and the gasket is detachably arranged between the column portion and the abutment portion.

[0011] In some embodiments of the present application, the gasket has an open slot, and the contour of the open slot is mutually adapted to the bolt so that the bolt can pass through the gasket.

[0012] In some embodiments of the present application, the cross-section of the open groove is U-shaped.

[0013] In some embodiments of the present application, the abutment portion is a boss structure, and the large diameter end surface of the abutment portion is detachably connected to the column portion through the bolts, and the small diameter end surface of the abutment portion is used to abut the frame beam part.

[0014] In some embodiments of the present application, the column portion includes a base block, a support section and a connecting section, one end of the support section is connected to the base block, and the other end is connected to the connecting section, the abutment portion is detachably connected to the connecting section by bolts, and an extension direction of the connecting section is perpendicular to an extension direction of the support section.

[0015] In some embodiments of the present application, a positioning through slot is arranged in the base block.

[0016] In some embodiments of the present application, the support section is located in the middle of the base block, and the number of the positioning through slots is two, and the two positioning through slots are respectively arranged on both sides of the support section.

[0017] In some embodiments of the present application, the thicknesses of the plurality of gaskets are not exactly the same.

[0018] The present application also provides a clamping method, which is applied to the above-mentioned deformation repair clamping tool, and includes the following steps:

[0019] After the frame beam part is roughened, it is left to stand in a natural state, and four corner points of the frame beam part are found;

[0020] The support column is matched with the four corner points respectively by bolts to complete the preliminary positioning;

[0021] Loosen the bolts at the fitting place between one of the support columns and the corner points. If there is a suspended corner point whose gap value is smaller than the preset gap, use the gasket to fill the suspended corner point. If there is a suspended corner point whose gap value is greater than or equal to the preset gap, adjust the diagonal corner point of the suspended corner point, and use the gasket to fill the suspended corner point and the diagonal corner point.

[0037] Figure 1 A schematic diagram of the structure of a deformation repair clamping tool provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of the first column 111 provided in an embodiment of the present application; Figure 3Schematic diagram of the structure of the gasket 10 provided in the embodiment of the present application. Figure 1-Figure 3 As shown, the deformation repair clamping tool is used to clamp the frame beam part 200, which may include a gasket 10 and a support column. There are multiple gaskets 10; the supporting column includes a first column 111, a second column 112, a third column 113 and a fourth column 114, and the first column 111, the second column 112, the third column 113 and the fourth column 114 are arranged in a quadrilateral on a horizontal plane; when in a first working state, one end of the frame beam part 200 is laid on the first column 111, and in response to the gap between the other end of the frame beam part 200 and the third column 113 being less than a preset gap, the gasket 10 is arranged on the third column 113; when in a second working state, one end of the frame beam part 200 is laid on the first column 111, and in response to the gap between the other end of the frame beam part 200 and the third column 113 being greater than or equal to the preset gap, multiple gaskets 10 are respectively arranged on the third column 113 and the first column 111, and the third column 113 and the first column 111 are diagonally arranged.

[0038] It is worth noting that the deformation repair clamping tool can be quickly clamped by four-point support, which greatly reduces the difficulty of clamping and adjustment of the operator and reduces the skill requirements of the operator. That is, during the deformation repair process of the frame beam part 200, due to the structural design of the tool, only one or two process boss gaps need to be adjusted, which greatly reduces the clamping workload. When two corner bosses need to be adjusted, only the same thickness gasket 10 needs to be used to fill them, and there is no need to perform repeated meter verification, which reduces the skill level requirements of the operator, reduces the difficulty and time of deformation repair, and improves product quality and the efficiency of deformation repair.

[0039] In specific use, the clamping method may include the following steps: after the frame beam part 200 is roughened, it is placed in a natural state for aging. After the aging is completed, the four corner points of the frame beam part 200 are found, such as Figure 1The corner points of the first column 111, the second column 112, the third column 113 and the fourth column 114 shown are located. For the first frame beam part 200, the support column can be reversely locked at the four corner points with bolts 1113 and then hoisted into the machine tool together. The part is straightened and aligned on the machine tool, and then the support column is locked or pressed on the machine tool workbench. The part has also completed the initial positioning at this time. Loosen the bolts 1113 between the support column and the part to allow the part to be freely on the support column. Due to the deformation of the part, the part must have a triangular point in contact with the support column at this time, and one corner point is in a suspended gap state. The gap is a manifestation of deformation and the weight of the part. If the gap value is less than the maximum gap value allowed by the process solution (i.e., the preset gap), use gaskets 10 to directly fill the suspended corner points. The remaining corner points do not need to be filled because they are already in rigid contact with the support column. Then, the four corner points are reversely locked with screws to repair the boss plane. If the gap value is greater than the maximum gap value allowed by the process plan (i.e. the preset gap), the corresponding diagonal points can be adjusted so that the two diagonal points are filled with gaskets 10 of equal thickness to ensure that the part margin is evenly divided. The other two corner points do not need to be filled because they are already in rigid contact with the support column. Then the four corner points are reversely locked with bolts 1113 to repair the boss plane.

[0040] Please refer to Figure 2 The first column 111, the second column 112, the third column 113 and the fourth column 114 all include a column portion 1111 and a butting portion 1112, the butting portion 1112 is detachably connected to the column portion 1111 by a bolt 1113, and one end of the butting portion 1112 is used to butt against the frame beam part 200, and the gasket 10 is detachably arranged between the column portion 1111 and the butting portion 1112.

[0041] It is worth noting that the detachable connection between the abutment portion 1112 and the column portion 1111 can avoid the need to replace the support column as a whole, reducing the cost of maintenance and replacement, and the gasket 10 is simple in design, low in cost, and reusable, further reducing the cost of use. In addition, the detachable design connected by the bolt 1113 makes it easy to disassemble and assemble the abutment portion 1112 and the column portion 1111, which is not only convenient for replacing worn parts, but also can quickly restore the function of the tooling and reduce downtime.

[0042] like Figure 3 As shown, the gasket 10 has an open slot 101 , and the profile of the open slot 101 is adapted to the bolt 1113 so that the bolt 1113 can pass through the gasket 10 .

[0043] In some embodiments of the present application, the cross section of the opening groove 101 is U-shaped.

[0044] It is understandable that the profile of the opening slot 101 is adapted to the bolt 1113, which can ensure that the gasket 10 will not deviate during the installation process and improve the stability of the clamping. At the same time, the U-shaped cross-section design enhances the bearing capacity of the gasket 10, avoids deformation or damage, and ensures reliability in long-term use. Depending on the specific implementation environment, a linear opening slot 101 or an opening slot 101 of other shapes can also be used. This embodiment is only an example of the shape of the opening slot 101, and does not constitute a limitation on its specific structure.

[0045] In this embodiment, the abutting portion 1112 is a boss structure, and the large diameter end surface of the abutting portion 1112 is detachably connected to the column portion 1111 through bolts 1113 , and the small diameter end surface of the abutting portion 1112 is used to abut the frame beam part 200 .

[0046] It should be understood that the large diameter end face of the abutment portion 1112 provides a larger contact area, making the connection with the column portion 1111 more stable, reducing the displacement or looseness caused by force during the clamping process, and ensuring the stability of the frame beam part 200 during the repair process. The small diameter end face of the abutment portion 1112 is directly used to abut the frame beam part 200, and different boss structures can be designed according to the shapes or sizes of different frame beam parts 200 to improve the ability of the tooling to adapt to different parts. It should also be understood that if Figure 1 As shown, the abutment portion 1112 can be rotated and then connected to the column portion 1111, thereby improving the application range of the support column (since different frame beam parts 200 require clamping directions in different directions, the abutment portion 1112 can be rotated, so more types of frame beam parts 200 can be clamped).

[0047] In this embodiment, the column portion 1111 includes a base block 1114, a support section 1115 and a connecting section 1116. One end of the support section 1115 is connected to the base block 1114, and the other end is connected to the connecting section 1116. The abutment portion 1112 is detachably connected to the connecting section 1116 by a bolt 1113, and an extension direction of the connecting section 1116 is perpendicular to an extension direction of the support section 1115.

[0048] It is worth noting that the base block 1114 provides a stable support foundation, and the support section 1115 connects the base block 1114 and the connecting section 1116 to form a stable bearing structure, ensuring that the tooling is not easy to tip over or shift during the repair process, thereby improving the reliability of use. In specific applications, the base block 1114 can be arranged in the plane of the machine tool. At the same time, the vertical extension direction design of the support section 1115 and the connecting section 1116 enables the force of the frame beam part 200 to be more evenly transmitted to the base block 1114 during the repair process, reducing the local stress concentration of the tooling and avoiding damage or deformation caused by mechanical imbalance.

[0049] Optionally, a positioning slot 1117 is arranged in the base block 1114 .

[0050] Specifically, the positioning slot 1117 allows the base block 1114 to be fixed to a working plane (such as the machine tool plane mentioned above), thereby ensuring the stability of clamping.

[0051] In this embodiment, the support section 1115 is located in the middle of the base block 1114 , and there are two positioning slots 1117 , which are respectively arranged on both sides of the support section 1115 .

[0052] In this embodiment, the thicknesses of the plurality of gaskets 10 are not completely the same.

[0053] Optionally, the thickness of the plurality of gaskets 10 includes one or a combination of 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm and 0.8 mm.

[0054] Specifically, the height of the support column can be designed according to the actual needs of the frame beam part 200, and can be completed by wire cutting processing, which is simple to manufacture, low cost and easy to use; the bolt 1113 can be a standard part - a cylindrical head hexagon screw; the U-shaped gasket 10 can be made of stainless steel strips of different specifications by stamping or cutting, which is low in price and easy to use. The thickness specifications are 0.05mm, 0.1mm, 0.2mm, 0.3mm, 0.5mm, and 0.8mm, and 6 specifications are ready for use, which can be applicable to more types of frame beam parts 200.

[0055] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application are included in the protection scope of the present application.
