Description

Technical Field

[0001] This invention belongs to the field of machining positioning technology, and specifically relates to coaxiality positioning fixtures, methods, controllers, and storage media for rotating equipment. Background Technology

[0002] In drying and reactor equipment, during the rotational operation of the shell, strict requirements are placed on the concentricity, perpendicularity, and radial runout of the sealing parts of the feed and discharge cylinders relative to the axis. If the concentricity, perpendicularity, and radial runout accuracy of the aforementioned equipment fails to meet the requirements, resulting in accuracy deviations, vibration, leakage, and wear (physical wear) will occur during equipment operation, thereby increasing the frequency of maintenance and directly affecting the normal operation and service life of the equipment.

[0003] With the rapid development of the chemical industry, equipment is trending towards larger sizes, with drying equipment and reactors reaching diameters of over 3 meters. In the original manufacturing process, the equipment's cylinder and ends were manufactured separately. Concentricity, perpendicularity, and radial runout accuracy were achieved through datum transfer and assembly control, employing specific technical measures. This manufacturing process involves many intermediate steps; if process control is poor, accumulated errors are difficult to eliminate, leading to physical wear and directly affecting the final assembly geometric accuracy. In particular, feed pipes and other structures are typically installed on the rotation axis of the feed and discharge cylinders of reaction equipment, thus requiring high coaxiality. However, in existing technologies, it is difficult to determine the central axis of the rotating cylinder during processing, resulting in the coaxiality accuracy between the processed feed or discharge cylinder and the rotating cylinder failing to meet design requirements, thus impacting equipment lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide a coaxiality positioning fixture, method, controller, and storage medium for a rotating body device, in order to solve the technical problem in the prior art where the central axis of the rotating body device is difficult to determine, resulting in low coaxiality between the rotating cylinder and the material cylinder.

[0005] To achieve the above objectives, the present invention provides a coaxiality positioning fixture for a rotating body device. The rotating body device includes a rotating cylinder, and a material cylinder is provided at the end of the central axis of the rotating cylinder. The coaxiality positioning fixture includes: a reference cylinder, the outer diameter of which is smaller than the inner diameter of the material cylinder, and one end of the reference cylinder for insertion into the material cylinder; a plurality of first length adjustable members, spaced apart along the outer circumferential wall of the same cross-section of the reference cylinder, all of which extend radially along the reference cylinder, and the length of the first length adjustable members extending beyond the outer circumference of the reference cylinder is adjustable, with the end of the first length adjustable member away from the reference cylinder for abutting against the inner circumferential wall of the material cylinder; and the aforementioned controller.

[0006] In some embodiments, the coaxiality positioning fixture further includes: a plurality of second length adjustable members, the plurality of second lengths being spaced apart along the outer peripheral wall of the same cross-sectional circumference of the reference cylinder, the plurality of second length adjustable members extending radially along the reference cylinder, the plurality of second length adjustable members and the plurality of first length adjustable members being located on different cross-sectional circumferences, the length of the second length adjustable members extending beyond the outer peripheral circumference of the reference cylinder being adjustable, and the end of the second length adjustable member away from the reference cylinder abutting against the inner peripheral wall of the material cylinder.

[0007] In some embodiments, both the first and second length adjustable components are adjusting screws.

[0008] In some embodiments, the coaxiality positioning fixture further includes: multiple support members arranged side by side with the first length adjustable member along the circumferential direction of the reference cylinder, the multiple support members being located on the outer periphery of the reference cylinder and away from one end of the rotating cylinder; and multiple third length adjustable members arranged one-to-one with the multiple support members, the third length adjustable members extending along the axial direction of the reference cylinder, the first end of the third length adjustable member being detachably connected to the support member, and the second end of the third length adjustable member facing the end face of the cylinder and used to abut against the end face.

[0009] In some embodiments, the length of the second end of the third length adjustable member extending beyond the support member is adjustable.

[0010] A second aspect of the present invention provides a method for coaxiality positioning of a rotating body device, the method being applied to the coaxiality positioning fixture of the aforementioned rotating body device, the method comprising:

[0011] Insert the reference cylindrical body into the material barrel;

[0012] Adjust multiple first length adjustable parts so that all multiple first length adjustable parts abut against the inner peripheral wall of the barrel;

[0013] Control the rotating cylinder to drive the reference cylinder to rotate;

[0014] Determine the rotational offset of the reference cylinder;

[0015] The lengths of multiple first length adjustment members extending out of the reference cylinder are adjusted according to the rotational offset until the rotational offset is lower than the preset offset threshold.

[0016] The position of the central axis of the rotating equipment is determined based on the position of the reference cylinder.

[0017] In some embodiments, the coaxiality positioning method further includes: determining the positioning reference of the machining equipment based on the position of the reference cylinder; removing the coaxiality positioning fixture; and using the machining equipment to perform coaxial machining on the inner peripheral wall of the cylinder.

[0018] In some embodiments, the step of determining the rotational offset of the reference cylinder includes: placing the detection end of the position detection element on the outer periphery of the reference cylinder; determining the offset of the reference cylinder for each preset angle rotation; and determining the rotational offset based on multiple offsets after the reference cylinder has rotated one revolution.

[0019] A third aspect of the present invention provides a controller comprising: a memory configured to store instructions; and a processor configured to retrieve instructions from the memory and, when executing the instructions, to implement the coaxiality positioning method of the rotary device described above.

[0020] A fourth aspect of the present invention provides a machine-readable storage medium storing instructions for causing a machine to perform the coaxiality positioning method of the rotary device described above.

[0021] The above technical solution provides a coaxiality positioning fixture for a rotating device. The rotating device includes a rotating cylinder and material cylinders disposed at both axial ends of the rotating cylinder. The coaxiality positioning fixture includes a reference cylinder and multiple first-length adjustable components disposed on the reference cylinder. The outer diameter of the reference cylinder is smaller than the inner diameter of the material cylinder. The reference cylinder and the multiple first-length adjustable components can be placed inside the material cylinder, and the lengths of the multiple first-length adjustable components extending beyond the outer circumference of the reference cylinder are adjustable. The ends of the multiple first-length adjustable components away from the reference cylinder are used to abut against the inner circumferential wall of the material cylinder. Using the above-mentioned coaxiality positioning fixture, the position of the center of the reference cylinder can be adjusted by repeatedly adjusting the lengths of the multiple first-length adjustable components extending beyond the outer circumference of the reference cylinder. After each adjustment, the rotational offset between the reference cylinder and the central axis of the rotating device can be determined by synchronously rotating the rotating device and the reference cylinder. By making multiple adjustments to ensure that the center of the reference cylinder and the rotating cylinder are on the same central axis, the central axis of the rotating equipment can be determined by the position of the reference cylinder, so as to facilitate coaxial processing of the material cylinder and extend the service life of the rotating equipment.

[0040] The coaxiality positioning fixture, method, controller, and storage medium of the rotary device according to the present invention are described below with reference to the accompanying drawings.

[0041] like Figure 1 The diagram shown is a schematic representation of the structure of a rotating body device according to an embodiment of the present invention; Figure 2 The diagram shown is a schematic representation of the coaxiality positioning fixture provided in an embodiment of the present invention being used in conjunction with a rotating body device; as shown Figure 3 As shown, Figure 2 A schematic diagram of the decomposition; such as Figure 4 The diagram shows a flowchart of a coaxiality positioning method according to an embodiment of the present invention. The rotary body device provided in this embodiment includes a rotary cylinder 1, with feed cylinders 2 at both axial ends of the rotary cylinder 1. The coaxiality positioning method uses a coaxiality positioning fixture for positioning. The coaxiality positioning fixture includes a reference cylinder 10 and a plurality of first length adjustable parts 20 disposed on the outer peripheral wall of the reference cylinder 10. The coaxiality positioning method includes:

[0042] S101, insert the reference cylindrical body 10 into the material cylinder 2.

[0043] S102, adjust the multiple first length adjustable parts 20 so that the multiple first length adjustable parts 20 abut against the inner peripheral wall of the barrel 2.

[0044] S103 controls the rotary cylinder 1 to drive the reference cylinder 10 to rotate.

[0045] S104, determine the rotational offset of the reference cylinder 10.

[0046] S105, adjust the length of the multiple first length adjustment members extending outside the reference cylinder 10 according to the rotation offset, until the rotation offset is lower than the preset offset threshold.

[0047] S106, determine the position of the central axis of the rotating body equipment based on the position of the reference cylinder 10.

[0048] The aforementioned coaxiality positioning fixture can be inserted into the cylinder 2, and by adjusting the length of the first length adjustable parts 20, all the first length adjustable parts 20 abut against the inner circumferential wall of the cylinder 2. When the rotary cylinder 1 rotates, it can drive the cylinder 2 to rotate together, and the rotation of the cylinder 2 can cause the first length adjustable parts 20 and the rotary cylinder 1 to rotate. When the rotary cylinder 1 rotates, if the distance between the rotation center of the reference cylinder 10 and the center of the reference cylinder 10 is far, then the reference cylinder 10 will have a positional offset during rotation, and the rotational offset of the reference cylinder 10 can be determined based on the positional offset. Based on the rotational offset, the length of the multiple first length adjustable parts extending outside the reference cylinder 10 can be adjusted, thereby adjusting the position of the center of the reference cylinder 10. When the rotational offset is determined to be lower than the preset offset threshold, it can be determined that the coaxiality between the center of the reference circle and the rotating cylinder 1 meets the requirements. Based on the position of the reference cylinder 10, the position of the central axis of the rotating body equipment can be determined, so as to facilitate the finishing of the material cylinder 2.

[0049] By employing the aforementioned coaxiality positioning method, the coaxiality requirements between the reference cylinder 10 and the rotating cylinder 1 can be met through multiple adjustments to the center position of the reference cylinder 10. Based on the position of the reference cylinder 10, the central axis position of the rotating equipment can be determined, and the material cylinder 2 can be precision-machined. The precision-machined material cylinder 2 exhibits high coaxiality with the rotating cylinder 1, thus extending the service life of the rotating equipment.

[0050] In one embodiment, the coaxiality positioning method further includes: determining the positioning datum of the machining equipment based on the position of the reference cylinder 10; removing the coaxiality positioning fixture; and using the machining equipment to perform coaxial machining on the inner peripheral wall of the cylinder 2. During the machining of the cylinder 2, the positioning datum of the machining equipment can be determined by the position of the reference cylinder 10. After the datum is determined, the coaxiality positioning fixture can be removed, and the inner peripheral wall of the cylinder 2 can be coaxially machined using the machining equipment, so that the coaxiality between the machined cylinder 2 and the rotating device meets the design requirements.

[0051] In one embodiment, after the inner peripheral wall of the barrel 2 is machined, the outer end face of the barrel 2 can be machined according to the machined inner peripheral wall so that the outer end face of the barrel 2 and the inner peripheral wall of the barrel 2 meet the perpendicularity requirements.

[0052] In one embodiment, the steps of controlling the rotation of the rotary cylinder 1 and determining the rotational offset of the reference cylinder 10 include: placing the detection end of the position detection element on the outer periphery of the reference cylinder 10; determining the offset of the reference cylinder 10 at each preset rotation angle; and determining the rotational offset based on multiple offsets after the reference cylinder 10 has rotated one revolution. In determining the rotational offset of the rotary device, the detection end of the position detection element can be placed on the outer periphery of the reference cylinder 10, and the rotary cylinder 1 can be controlled to rotate. The offset of the reference cylinder 10 position on one side is determined at each preset rotation angle. After the rotary cylinder 1 has rotated one revolution, the rotational offset of the reference cylinder 10 in various directions can be determined based on the offset. Based on this rotational offset, the lengths of multiple first length adjustment elements extending beyond the reference cylinder 10 can be adjusted to adjust the center position of the reference cylinder 10, thereby making the reference cylinder 10 coaxial with the rotary cylinder 1.

[0053] In one embodiment, a controller is provided, including: a memory configured to store instructions; and a processor configured to retrieve instructions from the memory and, when executing the instructions, to implement the coaxiality positioning method of the rotary device described above.

[0054] In one embodiment, such as Figure 2 and 3 As shown, a coaxiality positioning fixture for a rotating body device is provided. The rotating body device includes a rotating cylinder 1, and a material cylinder 2 is provided at the end of the central axis of the rotating cylinder 1. The coaxiality positioning fixture includes: a reference cylinder 10, a plurality of first length adjustable parts 20, and the aforementioned controller (not shown in the figure). The outer diameter of the reference cylinder 10 is smaller than the inner diameter of the material cylinder 2. One end of the reference cylinder 10 is used to be inserted into the material cylinder 2. The plurality of first length adjustable parts 20 are spaced apart along the outer peripheral wall of the same cross-section of the reference cylinder 10. The plurality of first length adjustable parts 20 extend radially along the reference cylinder 10. The length of the first length adjustable part 20 extending out of the outer periphery of the reference cylinder 10 is adjustable. The end of the first length adjustable part 20 away from the reference cylinder 10 is used to abut against the inner peripheral wall of the material cylinder 2.

[0055] The reference cylinder 10 needs to be inserted into the barrel 2. Therefore, the outer diameter of the reference cylinder 10 should be smaller than the inner diameter of the barrel 2 to ensure that the tooling can be used for coaxial positioning of the barrel 2 and the rotary cylinder 1. One end of the reference cylinder 10 is inserted into the barrel 2. Multiple first length adjustable parts 20 are spaced apart along the outer peripheral wall of the same cross-section of the reference cylinder 10, allowing the reference cylinder 10 to rotate with the barrel 2. When any one of the first length adjustable parts 20 is adjusted, the other first length adjustable parts 20 must also be adjusted accordingly so that all the first length adjustable parts 20 can abut against the inner peripheral wall of the barrel 2. Using the above-mentioned coaxial positioning tooling, the length of the first length adjustable parts 20 extending beyond the outer peripheral wall of the reference cylinder 10 can be adjusted according to the rotational offset of the reference cylinder 10 until the center of the reference cylinder 10 is coaxial with the rotary cylinder 1, so as to facilitate the machining of the inner peripheral wall and the outer end face of the barrel 2.

[0056] In one specific embodiment, the number of the first length adjustable member 20 and the second length adjustable member 30 is greater than or equal to three. The three outer peripheral points can determine a specific center of a circle. By setting the number of the first length adjustable member 20 and the second length adjustable member 30 to greater than or equal to three, the center position of the reference cylinder 10 can be accurately determined.

[0057] In one embodiment, such as Figure 2 and Figure 3 As shown, the coaxiality positioning fixture also includes multiple second-length adjustable components 30. These second-length adjustable components are spaced apart along the outer circumference of the same cross-section of the reference cylinder 10. All second-length adjustable components 30 extend radially along the reference cylinder 10. The multiple second-length adjustable components 30 and the multiple first-length adjustable components 20 are located on different cross-sectional circumferences. The length of each second-length adjustable component 30 extending beyond the outer circumference of the reference cylinder 10 is adjustable. One end of the second-length adjustable component 30, away from the reference cylinder 10, abuts against the inner circumference of the material cylinder 2. The multiple second-length adjustable components 30 can be arranged side-by-side with the multiple first-length adjustable components 20, allowing the reference cylinder 10 to rotate more stably with the material cylinder 2 after insertion, preventing the reference cylinder 10 from wobbling and affecting measurement accuracy.

[0058] In one embodiment, both the first length adjustable member 20 and the second length adjustable member 30 are adjusting screws. The adjusting screw can form a threaded connection with the reference cylinder 10, and the length of the adjusting screw extending out of the outer circumference of the reference cylinder 10 is adjustable and convenient, which simplifies the adjustment steps.

[0059] In one embodiment, such as Figure 2 and Figure 3As shown, the coaxiality positioning fixture also includes: multiple support members 40 and multiple third length adjustable members 50. The multiple support members 40 are arranged side by side with the first length adjustable member 20 along the circumferential direction of the reference cylinder 10. The multiple support members 40 are located on the outer periphery of the reference cylinder 10 and away from the end of the rotating cylinder 1. The multiple third length adjustable members 50 are arranged one-to-one with the multiple support members 40. The third length adjustable members 50 extend along the axial direction of the reference cylinder 10. The first end of the third length adjustable member 50 is detachably connected to the support member 40. The second end of the third length adjustable member 50 faces the end face of the material cylinder 2 and is used to abut against the end face, so that the end of the reference cylinder 10 closer to the rotating cylinder 1 can be more stably inserted into the material cylinder 2, making the detection more accurate.

[0060] In one embodiment, the length of the second end of the third length adjustable member 50 extending out of the support member 40 is adjustable. By adjusting the length of the second end of the third length adjustable member 50 extending out of the support member 40, the depth of the rotary cylinder 1 inserted into the material cylinder 2 can be adjusted so that the coaxiality positioning fixture can be adapted to different models of material cylinder 2.

[0061] In one specific embodiment, the third length adjustable member 50 can be selected as a screw, one end of which can be threaded to the support member, and the other end of which can abut against the outer end face of the reference cylinder 10. Screws are characterized by low cost and excellent adjustment performance, making them suitable for supporting and positioning the reference cylinder 10.
