[0002] Alloy precision castings are alloy parts with high precision, high surface quality, and complex shapes produced through precision casting processes. They typically include alloy structures such as bearings and rings. Deformation heat treatment of alloy precision castings is a process that combines plastic deformation with heat treatment to improve the performance of alloy precision castings while controlling their dimensional accuracy. Alloy precision casting deformation heat treatment straightening equipment is used to straighten alloy precision castings that have deformed after deformation heat treatment to ensure that their dimensional accuracy and shape meet design requirements.

The embodiments of this utility model will be described below based on its overall structure.

[0025] Reference Figures 1 to 7 In this embodiment of the utility model, a deformation heat treatment straightening device for precision alloy castings includes: a device box 1, characterized in that a circular groove 2 is provided through the top surface of the device box 1, a support column 3 is fixedly connected to the bottom surface inside the device box 1, a circular plate 4 is fixedly connected to the top of the support column 3, an inner ring force-applying base 5 is fixedly connected to the center of the circular plate 4, a hydraulic telescopic column 6 is provided on one side of the inner ring force-applying base 5, an arc-shaped force-applying block 7 is fixedly connected to the end of the hydraulic telescopic column 6, a driven gear disk 9 is movably sleeved on one end of the outer side of the support column 3, and a driving mechanism is fixedly connected to one end of the top surface of the device box 1. The motor 10 has a drive gear disk 11 fixedly sleeved on the outer side of its output shaft. A connecting block 12 is fixedly connected to one end of the top surface of the driven gear disk 9. An outer ring force-applying base frame 13 is fixedly connected to the top of the connecting block 12. A force-applying roller box 14 is slidably connected inside the outer ring force-applying base frame 13. A rotating motor 15 is fixedly connected to the top of the force-applying roller box 14. An outer ring force-applying roller 16 is fixedly sleeved on the outer side of the output shaft of the rotating motor 15. An adjusting screw 17 is screwed through one side of the outer ring force-applying base frame 13. The adjusting screw 17 is rotatably connected to the force-applying roller box 14.

[0026] Reference Figure 1 and Figure 6 The circular plate 4 is flush with the top surface of the equipment box 1, and there is a gap between it and the circular groove 2 to form a set of annular sliding groove structures. The inner ring force-applying base 5, the hydraulic telescopic column 6 and the arc-shaped force-applying block 7 are all provided in two sets, and are symmetrically arranged at the center of the top surface of the circular plate 4.

[0027] Using the above scheme: The annular alloy precision casting to be corrected is placed on the circular plate 4. Two sets of hydraulic telescopic columns 6 are activated, which push the arc-shaped force-applying block 7 to apply force in the direction of the long axis of the inner side of the ring. Since the inner ring force-applying base 5, the hydraulic telescopic columns 6 and the arc-shaped force-applying block 7 are all centrally symmetrically arranged, they can apply force to the inner side of the annular casting from multiple directions to correct the roundness of the inner side of the ring.

[0028] Reference Figures 1 to 3 The driven gear disk 9 is set close to the bottom surface of the circular plate 4, and a limiting ring 8 is fixedly sleeved on one end of the outer side of the support column 3. The driven gear disk 9 is kept on the same horizontal plane as the driving gear disk 11 and meshed with each other through the limiting ring 8 structure.

[0029] Using the above scheme: start the drive motor 10 so that its output shaft drives the drive gear disk 11 to rotate. The drive gear disk 11 meshes with the driven gear disk 9, thereby driving the driven gear disk 9 to rotate around the support column 3.

[0030] Reference Figure 4 and Figure 5 The number of connecting block 12, outer ring force-applying base frame 13 and the structure located inside it are all provided in two sets, and are symmetrically arranged on the top surface of driven gear disk 9. Force roller box 14 is located inside outer ring force-applying base frame 13. A limit groove 19 is opened on one side of force roller box 14. The end of adjusting screw 17 is fixed to limit block 18. Adjusting screw 17 is threaded through and screwed to one side of outer ring force-applying base frame 13, and is rotatably connected to force roller box 14 through limit groove 19 and limit block 18 structure with matching specifications.

[0031] The above scheme is adopted: the two sets of connecting blocks 12 on the top surface of the driven gear disk 9 rotate with it, driving the corresponding outer ring force-applying base frame 13 to rotate around the outer side of the annular casting. The rotating motor 15 is started so that its output shaft drives the outer ring force-applying roller 16 to rotate. The outer ring force-applying roller 16 contacts the outer side of the casting and applies pressure to flatten the outer side of the annular casting. By rotating the adjusting screw 17, due to the cooperation of the limiting block 18 and the limiting groove 19, the adjusting screw 17 pushes the force-applying roller box 14 to slide in the outer ring force-applying base frame 13, changing the distance and pressure between the outer ring force-applying roller 16 and the outer side of the annular casting, flexibly adapting to the correction requirements of castings of different specifications, and realizing the precise correction of the flatness of the outer side of the annular casting simultaneously.

[0032] Reference Figure 5 and Figure 6The driven gear disk 9 has several sets of chip leakage holes 20 arranged in a ring at one end, and the several sets of chip leakage holes 20 are all located on the driven gear disk 9 at the corresponding position in the annular groove between the circular groove 2 and the circular plate 4. The outer side of the circular plate 4 has a first engagement groove 21, and the inner side of the circular groove 2 has a second engagement groove 22. The circular plate 4 and the circular groove 2 are slidably engaged by an engagement slider 23. The bottom surface of the engagement slider 23 is provided with a cleaning brush 24. There are two sets of both the engagement slider 23 and the cleaning brush 24, which are symmetrically arranged in the annular groove between the circular groove 2 and the circular plate 4.

[0033] The above solution is adopted: During the straightening process, some debris may be generated on the surface of the casting due to contact, impact or pressure. The debris can be discharged and collected through the chip leakage hole 20 on the driven gear disk 9. The locking slider 23 that is slidably engaged between the circular plate 4 and the circular groove 2 can slide flexibly between the two. It is convenient to move the locking slider 23 along the annular groove by holding the locking slider 23 to drive the cleaning brush 24 on its bottom surface to assist in cleaning the annular groove between the circular groove 2 and the circular plate 4, so as to prevent the accumulation of debris from affecting the operation of the equipment.

[0034] Reference Figure 6 and Figure 7 Two sets of aggregate semicircular boxes 25 are symmetrically engaged on the outside of the support column 3. The two sets of aggregate semicircular boxes 25 are joined together to form a ring-shaped structure that can hold the support column 3 and receive debris. The contact surfaces of the two sets of aggregate semicircular boxes 25 are each embedded with a magnetic attraction plate 26 structure that attracts each other.

[0035] The above scheme is adopted: two sets of semi-circular collection boxes 25 hold the support column 3, and the magnetic suction plate 26 makes them fit tightly together. The connection and installation method is quick and convenient, and it is used to collect the debris falling from the chip leakage hole 20.

[0036] Reference Figure 1 and Figure 2 Equipment box 1 is hinged to one end with equipment door 27. There are two sets of equipment doors 27, which are symmetrically arranged at one end of equipment box 1.

[0037] With the above solution, the equipment door 27 can be opened to allow operators to maintain and replace internal components, and the semi-circular box 25 structure facilitates the loading and unloading of aggregates.

[0038] The working principle of this utility model is as follows: During use, the annular alloy precision casting to be corrected is placed on the circular plate 4. Two sets of hydraulic telescopic columns 6 are activated, pushing the arc-shaped force-applying blocks 7 towards the inner long axis of the ring. Since the inner ring force-applying base 5, the hydraulic telescopic columns 6, and the arc-shaped force-applying blocks 7 are all centrally symmetrically arranged, the annular alloy casting sleeved on the outside of the two sets of arc-shaped force-applying blocks 7 can be manually rotated and adjusted to gradually apply force to the inner side of the annular casting from multiple long axis directions, correcting the roundness of the inner side of the ring. The drive motor 10 is activated, causing its output shaft to drive the active gear disk 11 to rotate. The active gear disk 11 meshes with the driven gear disk 9, thereby driving the driven gear disk 9 to rotate around the support column 3. The two sets of connecting blocks 12 on the top surface of the driven gear disk 9 rotate with it, driving the corresponding outer ring force-applying base frame 13 to rotate around the outer side of the annular casting. The rotation motor 15 is activated, causing its output shaft to drive the outer ring force-applying roller 16 to rotate. The outer ring force-applying roller 16 contacts the outer side of the casting and applies force. Pressure is applied to the outer side of the annular casting to level it. By rotating the adjusting screw 17, due to the cooperation between the limiting block 18 and the limiting groove 19, the adjusting screw 17 pushes the force-applying roller box 14 to slide within the outer ring force-applying base frame 13, changing the distance and pressure between the outer ring force-applying roller 16 and the outer side of the annular casting. This flexibly adapts to the straightening needs of castings of different specifications, achieving precise straightening of the flatness of the outer side of the annular casting simultaneously. During the straightening process, the surface of the casting may be partially damaged due to contact, impact, or pressure. Debris can be discharged through the chip discharge hole 20 on the driven gear disk 9. Two sets of collecting semi-circular boxes 25 hold the support column 3, and the magnetic suction plate 26 makes them fit tightly to collect the debris falling from the gap. The locking slider 23 that slides between the circular plate 4 and the circular groove 2 can slide flexibly between the two. By holding the locking slider 23 and moving it along the annular groove, the cleaning brush 24 on its bottom surface can be driven to clean the annular groove between the circular groove 2 and the circular plate 4, preventing debris accumulation from affecting the operation of the equipment.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
