Description

Technical Field

[0001] This utility model relates to a straightening device for machining high-precision, high-temperature resistant alloy slender shafts, belonging to the field of shaft machining technology. Background Technology

[0002] High-precision, high-temperature alloy slender shafts are slender shaft parts with high precision and high-temperature resistance, typically made of nickel-based superalloy materials. This material is primarily composed of nickel, with other alloying elements added to enhance its overall performance. Nickel-based superalloys maintain good mechanical properties and oxidation resistance under high-temperature environments, making them particularly suitable for manufacturing parts that need to withstand high temperatures and heavy loads.

[0003] During the production or use of slender shaft parts, the middle part may be deformed and needs to be straightened. Currently, this is often done manually by applying a reverse force to the protrusion with tools such as hammers to restore the shaft to a straight state. This process consumes a lot of manpower and has low straightening efficiency. Utility Model Content

[0025] like Figures 1-4As shown, a straightening device for machining high-precision, high-temperature alloy slender shafts includes a worktable 1 and a slender shaft body 11. A shaft clamping mechanism 2 is installed on the top of the worktable 1, and an automatic straightening mechanism 3 is also installed on the top of the worktable 1. A protective mechanism 4 is also installed on the worktable 1. The automatic straightening mechanism 3 includes a protruding seat 31, which is fixedly installed on the top of the worktable 1. A track rod 32 is fixedly installed on the outer wall of the inner side of the protruding seat 31. A sliding seat 33 is slidably connected to the outer wall of the track rod 32. A second straightening block 38 is fixedly installed on the top of the sliding seat 33. A vertical plate seat 34 is fixedly installed on the top of the sliding seat 33. A horizontal plate seat 35 is fixedly installed on the front of the vertical plate seat 34. A hydraulic cylinder 36 is fixedly installed on the top of the horizontal plate seat 35. The telescopic end of the hydraulic cylinder 36 extends to the bottom of the horizontal plate seat 35 and is fixedly connected to a first straightening block 37. A support leg 39 is fixedly installed on the top of the moving seat 33, and a gas burner 391 is fixedly installed on the top of the support leg 39. A gas pipe 392 is fixedly connected to the outer wall of the gas burner 391, which can slide the sliding seat 33 on the outer wall of the track rod 32 to realize the function of adjusting the position of the second straightening block 38 left and right. Then, the second straightening block 38 is moved to the part of the slender shaft body 11 that needs to be straightened. Then, the gas burner 391 is controlled to work, outputting flames to the surface of the slender shaft body 11 to heat the slender shaft body 11, increase the temperature of the slender shaft body 11, and enhance its straightening effect. After the slender shaft body 11 is heated, the hydraulic cylinder 36 is controlled to extend, which can drive the first straightening block 37 to move downward, and cooperate with the second straightening block 38 to realize the function of automatically straightening the slender shaft body 11, reducing the consumption of manpower.

[0026] In this embodiment, a protrusion 331 is fixedly installed on the front of the sliding seat 33, and an electromagnet 332 is fixedly installed on the inner wall of the protrusion 331. The bottom of the electromagnet 332 is movably connected to the top of the workbench 1. A handle 333 is fixedly installed on the top of the protrusion 331. The shaft clamping mechanism 2 includes a first stand 21 and a second stand 23. The first stand 21 is fixedly installed on the top of the workbench 1, and a fixing sleeve 22 is fixedly installed on the right side of the first stand 21. The second stand 23 is fixedly installed on the top of the workbench 1 and located to the right of the first stand 21. A sliding rod 24 is slidably connected to the inner wall of the second stand 23. A movable sleeve 26 is fixedly installed on the left side of the sliding rod 24. The end of the slender shaft body 11 is movably inserted into the inner cavity of the fixing sleeve 22 and the movable sleeve 26. An elastic element 25 is fixedly installed on the right side of sleeve 26. The right side of elastic element 25 is fixedly connected to the left side of the second stand 23. After the position of sliding seat 33 is adjusted, the electromagnet 332 is energized to generate magnetic force, which causes the electromagnet 332 to be magnetically connected to the worktable 1, thereby locking the position of the sliding seat 33. When the electromagnet 332 is closed, the position of sliding seat 33 can be adjusted left and right. Pushing the movable sleeve 26 to the right, the movable sleeve 26 can compress the elastic element 25, thereby inserting the left end of the slender shaft body 11 into the fixed sleeve 22. Then, the movable sleeve 26 is released, and the reset force of the elastic element 25 drives the movable sleeve 26 to reset and insert into the right end of the slender shaft body 11, thus achieving the function of clamping the slender shaft body 11.

[0027] In this embodiment, the protective mechanism 4 includes a synchronizing cylinder 41, which is fixedly installed on the top of the workbench 1. The telescopic end of the synchronizing cylinder 41 extends to the bottom of the workbench 1 and is fixedly connected to a connector 42. A protective frame plate 43 is fixedly connected to the top of the connector 42. The outer wall of the protective frame plate 43 is slidably connected to the inner wall of the workbench 1. A transparent plate 44 is fixedly installed on the inner wall of the protective frame plate 43. A reinforcing rod 45 located on the front of the transparent plate 44 is fixedly installed on the inner wall of the protective frame plate 43. Through the protective frame plate 43 and the transparent plate 44, a reinforcing rod 45 is fixedly installed on the inner wall of the protective frame plate 43. The cooperation between the transparent plate 44 and the reinforcing rod 45 allows the operator to move to the front of the transparent plate 44 during the straightening process, thus protecting the operator from potential injury caused by flying debris during the straightening process and increasing safety. The operator can also observe the straightening status of the slender shaft body 11 through the transparent plate 44 and control the synchronous cylinder 41 to extend. Through the transmission of the connecting piece 42, the protective frame plate 43 can be retracted downwards, making it easier for the user to operate the components on the top of the workbench 1 from the front of the workbench 1.

[0028] The working principle of this utility model for a straightening device for machining high-precision, high-temperature resistant alloy slender shafts is as follows: In use, the movable sleeve 26 is pushed to the right, thereby inserting the left end of the slender shaft body 11 into the fixed sleeve 22. Then, the movable sleeve 26 is released, and the reset force of the elastic element 25 causes the movable sleeve 26 to reset and insert into the right end of the slender shaft body 11, thus clamping the slender shaft body 11. Then, the sliding seat 33 is slid, causing the second straightening block 38 to move to the part of the slender shaft body 11 that needs straightening. Next, the electromagnet 332 is energized to position the sliding seat 33. Then, the gas burner 391 is controlled to work, outputting flames to the surface of the slender shaft body 11 to heat it. After the slender shaft body 11 is heated, the hydraulic cylinder 36 is extended, causing the first straightening block 37 to move downwards, cooperating with the second straightening block 38 to achieve the function of automatically straightening the slender shaft body 11.
