Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tooling and fixture technology, and specifically relates to a tooling and fixture for processing oxide film samples of fracture surfaces of medium-thick aerospace aluminum alloy plates. Background Technology
[0002] Medium-thick aluminum alloy plates for aerospace applications typically require comprehensive performance, and their factory performance testing includes numerous items. The oxide film on the fracture surface is a crucial mandatory test item, serving as a key evaluation indicator for determining whether the plate is qualified and ready for delivery. The method for preparing the oxide film sample involves cutting a wedge-shaped groove (V-shaped) along the rolling direction at the center of the billet's thickness. The groove has a width and depth not exceeding one-third of the billet's length. Finally, the sample is broken in one go using a press, and the oxide film on the thickness sample is observed.
[0003] The traditional method for processing V-shaped grooves in fracture oxide film samples is to use a wire EDM machine with a set program. This wire EDM process is very slow, and each batch of fracture oxide film samples usually requires 8-10 samples. Therefore, the efficiency of processing fracture oxide film samples using the traditional wire EDM method is very low, which seriously affects the product testing progress and thus has an adverse impact on the product delivery time. Furthermore, wire EDM inevitably produces faults such as wire breakage during operation, and replacing the molybdenum wire used in wire EDM takes time, which not only affects production efficiency, but also the continuity of wedge groove processing is affected by mechanical failures.
[0004] Therefore, in order to solve the above-mentioned technical problems, it is urgent to design a tooling fixture specifically for processing oxide film samples of medium-thick aluminum alloy fracture surfaces, and to use a milling machine to complete the processing of wedge-shaped grooves on the oxide film samples of medium-thick aluminum alloy fracture surfaces. Utility Model Content
[0005] The purpose of this utility model is to provide a tooling fixture for processing fracture oxide film samples of medium-thick aerospace aluminum alloy plates. This tooling fixture is suitable for milling machines, using a milling machine instead of a traditional wire EDM machine to achieve rapid processing of fracture oxide film samples. During processing, the fracture oxide film sample is placed on this tooling fixture, and a wedge-shaped groove (V-shaped) is quickly milled out using a milling cutter, improving production efficiency and processing quality. The specific technical solution is as follows:
[0006] A machining fixture for aerospace aluminum alloy medium-thick plate fracture oxide film samples includes a vise assembly mounted on a milling machine platform. An auxiliary component is mounted on the vise assembly via a connector. The sample to be processed is placed on the auxiliary component and clamped and fixed by the vise assembly. The auxiliary component places the sample to be processed at an angle so that the rotation center line of the milling cutter forms an angle of not equal to 90° with the surface to be processed of the sample. A V-groove is machined on the surface to be processed of the sample by the milling cutter.
[0007] Preferably, the vise assembly includes a mounting base, a stationary clamping part, a sliding clamping part, and a manual drive part. The mounting base is mounted on the milling machine platform, the stationary clamping part is mounted on the mounting base, the sliding clamping part is slidably disposed on the stationary clamping part, and the manual drive part connects the stationary clamping part and the sliding clamping part. By rotating the manual drive part, the stationary clamping part and the sliding clamping part can be moved closer or further apart.
[0008] Preferably, the auxiliary component is mounted on the stationary clamping part via the connector. The auxiliary component includes a vertical plate, a support plate, and a mounting plate. The vertical plate is vertically mounted on the mounting plate. The mounting plate is connected to the stationary clamping part via the connector. The support plate is mounted obliquely on the vertical plate. The support surface of the support plate and the mounting surface of the vertical plate form an acute angle.
[0009] Preferably, the acute angle is 45°.
[0010] Preferably, the connecting element is a bolt.
[0011] Preferably, the width of the support surface of the auxiliary component is smaller than the processing clamping length of the sample to be processed, so that the sample to be processed is clamped by the vise assembly.
[0012] Preferably, the auxiliary component is made of aluminum alloy.
[0013] Compared with existing technologies, this utility model has the following beneficial effects:
[0014] 1. This utility model provides a tooling fixture for processing oxide film samples of medium-thick aluminum alloy fracture surfaces. Using this tooling fixture, wedge grooves can be processed using a vertical milling cutter on a milling machine. This processing method perfectly replaces the traditional wire cutting process for processing wedge grooves, greatly improving the processing efficiency of samples.
[0015] 2. The machining fixture provided by this utility model, with the assistance of the fixture, can control the depth of the wedge groove by controlling the feed rate of the milling cutter, thereby improving the applicability and practicality of machining oxide film samples with fracture surfaces.
[0016] 3. The processing fixture provided by this utility model has a simple structure and is easy to process and manufacture. By using a combination of traditional vises and auxiliary components, the batch processing of oxide film samples of plate fracture surfaces of all thicknesses can be achieved simply by adjusting the clamping stroke of the vise (the clamping parts at both ends of the vise correspond to the upper and lower rolling surfaces of the plate, i.e. the original thickness of the plate).

[0027] Example
[0028] like Figures 1 to 3 As shown, a tooling fixture for processing oxide film samples of medium-thick aluminum alloy fracture surfaces includes a vise assembly 20 mounted on a milling machine platform 10. An auxiliary component 40 is mounted on the vise assembly 20 via a connector 30. The sample 50 to be processed is placed on the auxiliary component 40 and clamped and fixed by the vise assembly 20. The auxiliary component 40 places the sample 50 at an angle so that the rotation center line of the milling cutter 60 forms an angle of not equal to 90° with the surface to be processed of the sample 50. A V-groove 51 is machined on the surface to be processed of the sample 50 by the milling cutter 60.
[0029] Preferably, the vise assembly 20 includes a mounting base 21, a stationary clamping part 22, a sliding clamping part 23, and a manual drive part 24. The mounting base 21 is mounted on the milling machine platform 10, the stationary clamping part 22 is mounted on the mounting base 21, the sliding clamping part 23 is slidably disposed on the stationary clamping part 22, and the manual drive part 24 connects the stationary clamping part 22 and the sliding clamping part 23. By rotating the manual drive part 24, the stationary clamping part 22 and the sliding clamping part 23 can be moved closer or further apart. The clamping stroke of the vise assembly 20 is parallel to the running direction of the milling cutter.
[0030] In some preferred embodiments, the auxiliary component 40 is mounted on the stationary clamping part 22 via the connector 30. The auxiliary component 40 includes a vertical plate 41, a support plate 42, and a mounting plate 43. The vertical plate 41 is vertically mounted on the mounting plate 43. The mounting plate 43 is connected to the stationary clamping part 22 via the connector 30, which is a bolt. Specifically, two threaded holes spaced 10 cm apart are machined on the side near the stationary clamping part 22, and two through holes spaced 10 cm apart are machined on the mounting plate 43. The through holes correspond to the threaded holes, so that the... The mounting plate 43 is bolted to one side of the stationary clamping part 22. The support plate 42 is mounted obliquely on the vertical plate 41. The support surface of the support plate 42 and the mounting surface of the vertical plate 41 form an acute angle. It is worth mentioning that the acute angle is 45°. Since the cross-section of the milling cutter 60 is square, when the milling cutter 60 rotates, it can leave a V-shaped groove 51 on the surface of the sample to be processed 50, thus completing the processing of the wedge-shaped groove (V-shaped) of the fracture oxide film sample. The size of the processed wedge-shaped groove can also be adjusted by adjusting the feed rate of the milling cutter 60.
[0031] In some preferred embodiments, in order to ensure that the vise assembly 20 can hold the sample 50 to be processed without affecting the clamping of the sample 50, while the sample 50 can be supported by the auxiliary member 40 and the surface of the sample 50 to be processed can be adjusted by the auxiliary member 40, the width of the supporting surface of the auxiliary member 40 is smaller than the processing clamping length of the sample 50. The sample 50 is placed on the auxiliary member 40, and the two sides of the sample 50 in the processing direction are clamped by the stationary clamping part 22 and the sliding clamping part 23. The sample 50 is clamped onto the vise assembly 20 by rotating the manual drive part 24.
[0032] In some preferred embodiments, the auxiliary component 40 is made of aluminum alloy to facilitate the processing of the auxiliary component 40.
[0033] Next, the workflow and principles of this embodiment will be described in detail to enable those skilled in the art to better understand this utility model:
[0034] The vise assembly 20 is mounted on the milling machine platform 10, ensuring that the clamping stroke of the vise is parallel to the running direction of the milling cutter 60. The machined auxiliary component 40 is mounted on the stationary clamping part 22 of the vise assembly 20 via the connector 30 (bolt). The sample 50 to be processed (fracture oxide film blank) is placed on the auxiliary component 40. Under the support of the auxiliary component 40, the surface to be processed of the sample 50 forms a 45° angle with the rotation center line of the milling cutter 60. The drive... The manual drive unit 24 is used to clamp the sample 50 to be processed by the vise assembly 20. When the milling cutter 60 of the milling machine is working, it can process two surfaces at the same time. The included angle between the two surfaces is exactly 90°. Therefore, when the milling cutter 60 rotates and moves forward, it can leave a V-shaped groove 51 on the surface of the sample 50 to be processed, thus completing the processing of the wedge-shaped groove (V-shaped) of the fracture oxide film sample. The size of the processed wedge-shaped groove can also be adjusted by adjusting the feed rate of the milling cutter 60, which greatly improves the processing efficiency of the sample.
[0035] In summary, this utility model provides a tooling fixture for processing fracture oxide film samples of medium-thick aerospace aluminum alloy plates. Using this fixture, wedge grooves can be machined using a vertical milling cutter on a milling machine, perfectly replacing the traditional wire EDM process for wedge grooves and significantly improving sample processing efficiency. Furthermore, the tooling fixture provided by this utility model allows for control of the wedge groove depth by adjusting the milling cutter's feed rate, enhancing the applicability and practicality of fracture oxide film sample processing. The tooling fixture provided by this utility model has a simple structure, is easy to process and manufacture, and utilizes a combination of a traditional vise and auxiliary components. By simply adjusting the vise's clamping stroke (the clamping parts at both ends of the vise correspond to the upper and lower rolled surfaces of the plate, i.e., the original thickness of the plate), batch processing of fracture oxide film samples of all plate thicknesses can be achieved.
