Description

Technical Field

[0001] This utility model relates to the field of aircraft parts processing technology, and more specifically, to a device for controlling deformation during heat treatment of aircraft parts. Background Technology

[0002] In the manufacturing of aircraft parts, heat treatment is often used to soften metal materials before plastic deformation to meet the processing requirements of complex structures. However, traditional processes typically involve separate heat treatment furnaces and forming equipment operating in stages. This results in heated parts being easily exposed to cold air during transfer, causing them to cool and harden rapidly. This significantly increases the resistance to subsequent deformation, forcing operators to repeatedly heat the parts or apply greater forming forces. This not only affects processing efficiency but may also lead to uneven material properties due to temperature fluctuations.

[0003] In addition, existing clamping devices mostly adopt a fixed structure, which makes it difficult to quickly adjust the positioning and deformation position after heating. Multiple disassembly and reassembly are required during operation, and the positioning accuracy is easily affected by human factors. Although some equipment attempts to integrate heating and forming functions, it lacks modular adjustment design and cannot flexibly adjust the position of the force application point according to the size and deformation requirements of the parts. Moreover, the positioning stability is insufficient in high-temperature environments, and it is easy to slip and deviate due to thermal expansion. Therefore, in order to address the above technical problems, a deformation control device for heat treatment of aircraft parts is proposed here. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-8The present invention proposes an aircraft component heat treatment deformation control device, including an operating table 1, an installation groove 2 on the upper side of the operating table 1, a heating mechanism installed inside the installation groove 2, two sets of symmetrically arranged slide seats 5 slidably connected to both sides of the installation groove 2, and a heat-insulating handle 11 fixedly connected between the two sets of slide seats 5, a positioning mechanism installed on the outside of the slide seats 5, a fixed seat 14 fixedly connected to the outside of the operating table 1, a support plate 15 slidably connected to the upper side of the fixed seat 14, a translation mechanism installed between the fixed seat 14 and the support plate 15, a vertical rod 19 fixedly connected to the upper side of the support plate 15, and a deformation mechanism installed on the inner side of the vertical rod 19.

[0027] The heating mechanism includes a power supply base 3 and a heating rod 4. The power supply base 3 is fixedly connected to both sides of the inside of the mounting groove 2, and the heating rod 4 is fixedly connected between two sets of power supply bases 3. The number of heating rods 4 is several sets and arranged horizontally. Through the horizontal uniform arrangement design of multiple sets of heating rods 4, a stable and wide-coverage heating area can be provided for aircraft parts, thereby improving softening efficiency.

[0028] The upper side of the operating table 1 has two sets of symmetrically arranged slide grooves 6. The bottom of the slide block 5 is fixedly connected to a slider 7, and the slider 7 is limited and slidably connected to the inner side of the slide groove 6. The matching and limiting design of the slide groove 6 and the slider 7 can ensure that the slide block 5 moves smoothly and avoids deviation or shaking that affects the positioning accuracy.

[0029] The positioning mechanism includes a screw 8, a pressure plate 9, and a fixing nut 10. The screw 8 is threaded to the upper side of the slide block 5, the pressure plate 9 is fixedly connected to the bottom of the screw 8, and the fixing nut 10 is threaded to the outer side of the screw 8 and abuts against the upper surface of the slide block 5. The heat-insulating handle 11 is made of heat-insulating material. The heat-insulating handle 11 made of heat-insulating material can facilitate the linkage and sliding of the two sets of slide blocks 5, and can also prevent heat conduction from causing burns to the staff.

[0030] A positioning hole 12 is provided on one side of the slider 7, and a positioning rod 13 is fixedly connected to one end of the inner side of the slide groove 6. The positioning rod 13 and the positioning hole 12 are matched. The insertion and engagement of the positioning rod 13 and the positioning hole 12 can quickly lock the moving end position of the slide block 5 to prevent accidental slippage during processing.

[0031] The translation mechanism includes a drive motor 16, a lead screw 17, and a connecting block 18. The drive motor 16 is fixedly connected to the outside of the fixed base 14. The lead screw 17 is fixedly connected to one side of the drive motor 16 and rotatably connected to the inside of the fixed base 14. The connecting block 18 is slidably connected to the inside of the fixed base 14, and the connecting block 18 and the lead screw 17 are connected by a thread. The support plate 15 is fixedly connected to the upper side of the connecting block 18. Through the threaded transmission between the lead screw 17 and the connecting block 18, the rotational motion of the drive motor 16 can be converted into the precise lateral displacement of the support plate 15.

[0032] The deformation mechanism includes a lifting groove 20, a clamping plate 21, a stop plate 22, a pull rope 23, and a pull rod 24. The lifting groove 20 is opened on one side of the upright 19. The clamping plate 21 is slidably connected to the inside of the lifting groove 20. The stop plate 22 is fixedly connected to the outside of the clamping plate 21. The limiting and guiding effect of the lifting groove 20 on the clamping plate 21 can ensure that the force applied by the stop plate 22 is perpendicular, and avoid skewed deformation during bending.

[0033] The pull rope 23 is fixedly connected to the upper side of the clamping plate 21, and the end of the pull rope 23 passes through the upper side of the upright 19 and is fixedly connected to the pull rod 24. The linkage design of the pull rope 23 and the pull rod 24 allows the operator to control the lifting and pressing of the pressure plate 22 by manually pulling on one side, simplifying the operation steps.

[0034] The working principle of a heat treatment deformation control device for aircraft parts based on an embodiment is as follows: When using this heat treatment deformation control device, the operator first places the aircraft parts to be treated between two sets of symmetrically distributed slides 5 on the operating table 1. By rotating the screw 8 above the slide 5, the bottom pressure plate 9 is driven to move downward and come into close contact with the surface of the parts. Then, the fixing nut 10 on the outside of the screw 8 is tightened to lock its position, realizing the quick clamping of the parts. After clamping is completed, the operator holds the heat-insulating handle 11 between the slides 5 and moves the parts horizontally to the top of the mounting groove 2. At this time, the power supply bases 3 on both sides of the mounting groove 2 are energized for multiple sets of horizontally arranged electric heating rods 4, which release heat to uniformly heat and soften the parts. Once the parts have reached the predetermined softening level, the operator pushes the slide block 5 along the slide groove 6 to the other end using the heat-insulating handle 11. The slide block 5 is then precisely positioned by engaging the positioning rod 13 inside the slide groove 6 through the positioning hole 12 on the bottom slider 7. Subsequently, the operator manually pulls the top lever 24 of the upright 19 upwards, pulling the clamping plate 21 upwards along the lifting groove 20 via the pull rope 23. This causes the outer abutment plate 22 to contact the softened parts and apply pressure, resulting in a controllable bending deformation. If the bending position needs adjustment, the drive motor 16 on the fixed base 14 can be activated, driving the lead screw 17 to rotate and causing the connecting block 18 and support plate 15 to move laterally, thereby changing the horizontal position of the upright 19 and the deformation mechanism. This device, by integrating heating softening and deformation control functions, effectively shortens the connection time between heat treatment and forming processes, preventing increased deformation resistance due to cooling hardening of the parts. Simultaneously, the modular adjustment design improves bending accuracy and operational efficiency.
