[0043] In the related art, the red sleeve process is used to connect the cylinder and the web plate with interference to connect the cylinder and the web plate together to form a whole, thereby increasing the strength. When the cylinder and the web plate are red sleeved, a simple method is to use auxiliary iron rods and hammers to knock the web plate into the cylinder. However, this simple assembly method makes the position of the web plate in the cylinder inaccurate, the installation position size deviation is large, and the web plate is easy to be skewed.

[0044] As shown in FIGS. 1 to Figure 6To solve the above technical problems, the embodiment of the present application provides a red sleeve tool, which comprises a workbench 100, a stand column 300 and N-stage positioning assemblies 400. The top of the workbench 100 has a reference surface 110. The bottom end of the stand column 300 is connected with the reference surface 110, and the stand column 300 and the reference surface 110 are vertically arranged. The N-stage positioning assemblies 400 are arranged in the axial direction of the stand column 300 in sequence, and satisfy N≥2, N being a positive integer. The positioning assembly 400 comprises a mounting sleeve 410 and at least two supporting members 430. The mounting sleeve 410 is coaxially and rotatably arranged in the stand column 300. The at least two supporting members 430 are uniformly arranged along the circumferential direction of the mounting sleeve 410. One end of the supporting member 430 close to the mounting sleeve 410 is hingedly connected with the mounting sleeve 410 and forms a rotation axis, and the rotation axis and the axis of the stand column 300 are arranged in parallel. The side of the supporting member 430 away from the axis of the mounting sleeve 410 has a first clamping groove 433, which is used for accommodating part of the web plate 500. The extension direction of the first clamping groove 433 is parallel to the cross section of the stand column 300, so that the axis of the web plate 500 is parallel to the axis of the stand column 300. In the axial direction of the stand column 300, there is an axial gap between the web plate 500 and the first clamping groove 433. In the radial direction of the stand column 300, there is a radial gap between the inner side of the web plate 500 and the first clamping groove 433, so that the supporting member 430 can rotate around the rotation axis.

[0045] In these embodiments, the present application designs a red sleeve tool, aiming to solve the problem of inaccurate installation position and easy deflection of the web plate 500 in the traditional red sleeve process. Through the design of the workbench 100, the stand column 300 and the multi-stage positioning assembly 400, the accurate positioning and stability of the web plate 500 during installation are ensured, and the installation quality is improved. Specifically, the key components of the red sleeve tool include:

[0046] The workbench 100 provides a stable work platform, and the reference surface 110 on the top thereof serves as the basic reference surface of the entire tool.

[0047] For example, in this embodiment, the tabletop of the workbench 100 is the reference surface 110. Of course, in other embodiments, the side surface of the workbench 100 can also be set as the reference surface 110.

[0048] The stand column 300 is vertically fixed on the workbench 100 and serves as the supporting structure of the positioning assembly 400, ensuring the relative positional relationship between the components. For example, the stand column 300 is designed in a cylindrical shape. Of course, in other embodiments, the stand column 300 can be designed in a prismatic shape, an elliptical cylindrical shape, etc.

[0049] N-stage positioning assembly 400 is the core part of the tooling, and is composed of a mounting sleeve 410 and a plurality of support members 430. The mounting sleeve 410 can rotate freely around the stand 300, while the support members 430 are fixed to the mounting sleeve 410 by hinging and can rotate around a rotation axis parallel to the axis of the stand 300. Each support member 430 is equipped with a first clamping groove 433 for accurately accommodating and positioning a portion of the web plate 500, and two support members 430 of the positioning assembly 400 are used to support two portions of the web plate 500, thereby ensuring that the axis of the web plate 500 is parallel to the axis of the stand 300.

[0050] For example, in the present embodiment, the number of positioning assemblies 400 is three. Of course, in other embodiments, the number of positioning assemblies 400 can also be four, five, six, seven, etc.

[0051] Similarly, in the present embodiment, the number of support members 430 of the positioning assembly 400 is three. Of course, in other embodiments, the number of support members 430 can also be four, five, six, seven, etc.

[0052] In addition, the axial gap and radial gap mentioned in the design allow the support members 430 to be flexibly adjusted without affecting the correct installation of the web plate 500, thereby adapting to web plates 500 of different sizes or shapes, increasing the applicability and flexibility of the tooling. Moreover, the axial gap and radial gap are used to ensure that the web plate 500 is in a movable state, avoiding the web plate 500 being clamped in the clamping groove, thereby ensuring that the web plate 500 does not interfere with the rotation of the support member 430 around the rotation axis, to achieve the separation of the web plate 500 and the clamping groove, and to prepare for the subsequent removal of the tooling from the cylinder 200.

[0053] As can be easily understood, after the installation is completed, the heated cylinder 200 is lifted and falls from top to bottom to the reference surface 110 of the workbench 100, and the red sleeve assembly is quickly completed before the cylinder 200 cools down. During this process, the cylinder 200 can be knocked to speed up the assembly. After the cylinder 200 cools down, the cylinder 200 and the web plate 500 are connected together in interference fit, at this time, the support members 430 are rotated to achieve the separation of the first clamping groove 433 and the web plate 500, thereby making the red sleeve tooling as a whole separate from the web plate 500.

[0054] Obviously, the design effectively solves the problems existing in the traditional method through the innovation of mechanical structure, improves the quality and efficiency of the connection between the web plate 500 and the cylinder 200, and has important application value for the industrial field that needs high-precision assembly.

[0055] In some embodiments, the reference surface 110 is a horizontal reference surface 110.

[0056] In these embodiments, the reference surface 110 is designed as a horizontal reference surface 110, which brings additional advantages and conveniences. The horizontal reference surface 110 can ensure that the column 300 remains completely perpendicular to the ground, which is crucial for the stability and accuracy of the entire tooling system. Precise control of the perpendicularity helps to improve the assembly accuracy of the web plate 500 and other components. The horizontal reference surface 110 makes it easier to operate the tooling during initial installation and subsequent calibration. By using a simple level or other measuring tools, the levelness of the reference surface 110 can be quickly confirmed and adjusted, ensuring that the tooling system is always in optimal working condition.

[0057] It should be noted that the horizontal reference surface 110 helps to improve the repeatability of the assembly process. Each time the assembly is performed, the same horizontal reference surface 110 can be relied upon to ensure the consistent positioning of the components, which is very important for mass production and quality control.

[0058] In addition, the design of the horizontal reference surface 110 simplifies the overall structure of the tooling and reduces unnecessary complexity. For example, additional inclination correction devices are not needed, thereby reducing manufacturing costs and maintenance difficulty. Moreover, the horizontal reference surface 110 makes it easier for operators to observe the details of the assembly process, especially when making fine adjustments. This helps to improve work efficiency and assembly quality. Furthermore, the horizontal reference surface 110 can reduce safety hazards caused by unstable tooling, especially during the assembly of heavy components, as the stability of the tooling directly affects the safety of the operators.

[0059] In some embodiments, the first clamping groove 433 is arranged to extend along the circumference of the column 300.

[0060] In these embodiments, the first clamping groove 433 is arranged to extend along the circumference of the column 300, and the axis of the groove bottom of the first clamping groove 433 coincides with the axis of the column 300. The circumferentially extending first clamping groove 433 can better prevent the web plate 500 from being deflected during the assembly process, ensuring that the axis of the web plate 500 always remains parallel to the axis of the column 300. Moreover, it avoids interference with the rotation of the support 430.

[0061] Furthermore, the circumferentially extending first clamping groove 433 can cause the web plate 500 to be uniformly stressed in all directions, reducing local stress concentration and improving the stability of the assembly process.

[0062] In some embodiments, the mounting sleeve 410 is coaxially sleeved on the column 300; the positioning assembly 400 further comprises a positioning sleeve 440, the positioning sleeve 440 is coaxially sleeved on the column 300, and the top end of the positioning sleeve 440 abuts against the bottom end of the mounting sleeve 410.

[0063] In these embodiments, the mounting sleeve 410 is coaxially sleeved on the column 300, and the positioning assembly 400 further comprises a positioning sleeve 440, which is coaxially sleeved on the column 300, and the top end of the positioning sleeve 440 and the bottom end of the mounting sleeve 410 abut. Obviously, by replacing the positioning sleeve 440 with different length sizes, the height of the mounting sleeve 410 can be adjusted, thereby adjusting the position of the web plate 500.

[0064] Briefly, according to the axial position of the web plate 500 in the cylinder 200, a positioning sleeve 440 with a suitable length is selected, so that the web plate 500 is installed at a set position in the cylinder 200. That is, the positioning sleeve 440 can be provided in multiple types, and the lengths of the multiple types of positioning sleeves 440 are different.

[0065] For example, the first-stage positioning assembly 400 is close to the reference surface 110, and the Nth-stage positioning assembly 400 is away from the reference surface 110. The top end of the positioning sleeve 440 of the first-stage positioning assembly 400 and the bottom end of the mounting sleeve 410 abut, and the bottom end of the positioning sleeve 440 and the reference surface 110 abut. The top end of the positioning sleeve 440 of the Nth-stage positioning assembly 400 and the bottom end of the mounting sleeve 410 abut, and the bottom end of the positioning sleeve 440 and the top end of the positioning sleeve 440 of the Nth-stage positioning assembly 400 abut.

[0066] Obviously, the abutment design of the positioning sleeve 440 and the mounting sleeve 410 can effectively prevent the mounting sleeve 410 from sliding in the axial direction, and ensure that the position of the web plate 500 remains unchanged during assembly. That is, the combined design of the positioning sleeve 440 and the mounting sleeve 410 makes the tooling have better modular characteristics, and the positioning sleeve 440 and the mounting sleeve 410 can be replaced or adjusted according to different assembly requirements, improving the flexibility and adaptability of the tooling.

[0067] In some embodiments, the support 430 comprises a supporting plate 432 and a pressing plate 431, one end of the supporting plate 432 is hinged to the mounting sleeve 410, the other end of the supporting plate 432 is connected to the pressing plate 431, the supporting plate 432 and the pressing plate 431 are arranged in sequence in the axial direction of the column 300, and the gap between the ends of the supporting plate 432 and the pressing plate 431 away from the column 300 defines a first clamping groove 433.

[0068] In these embodiments, this design choice further optimizes the structure and function of the red sleeve tooling. The first clamping groove 433 between the support plate 432 and the pressing plate 431 can precisely limit the web plate 500, ensuring that the web plate 500 is fixed in position in the axial and radial directions, improving positioning accuracy. The support plate 432 and the pressing plate 431 contact the web plate 500 from different directions, providing multiple contact points to ensure that the web plate 500 is positioned more accurately in all directions. The double-layer structure of the support plate 432 and the pressing plate 431 provides stronger support, preventing the web plate 500 from deflecting or moving during assembly, improving the stability of the entire tooling.

[0069] In these embodiments, the first clamping groove 433 between the support plate 432 and the pressing plate 431 is designed so that the web plate 500 can be quickly and accurately placed into the clamping groove, reducing assembly time and complexity. The operator only needs to place the web plate 500 into the first clamping groove 433 to complete the initial positioning, simplifying the assembly steps and improving work efficiency.

[0070] Optionally, the gap between the support plate 432 and the pressing plate 431 can be designed to be adjustable to accommodate web plates 500 of different thicknesses and shapes, improving the flexibility and adaptability of the tooling. The support plate 432 and the pressing plate 431 can be designed as detachable or replaceable modules, facilitating adjustment and replacement according to different assembly requirements.

[0071] In some embodiments, the red sleeve tooling further comprises a plurality of driving assemblies 600, which can simultaneously connect with one support piece 430 on different positioning assemblies 400, and the driving assembly 600 is used to drive the corresponding support piece 430 to rotate around the rotation axis.

[0072] In these embodiments, the driving assembly 600 can automatically drive the support piece 430 to rotate around the rotation axis, facilitating the separation of the support piece 430 and the web plate 500 after the web plate 500 is assembled. Moreover, a single driving assembly 600 can drive multiple support pieces 430 to rotate, which can significantly improve assembly efficiency and shorten assembly time, especially in mass production, which can greatly improve production speed.

[0073] For example, the number of driving assemblies 600 is three, the number of positioning assemblies 400 is three, and the number of support pieces 430 of each positioning assembly 400 is three, i.e., each driving assembly 600 is connected with three support pieces 430, and each driving assembly 600 can simultaneously drive three support pieces 430 located on different driving assemblies 600 to rotate.

[0074] In some embodiments, all the support pieces 430 connected to the same driving assembly 600 are arranged in sequence in the axial direction of the column 300.

[0075] The driving assembly 600 comprises a driving rod 610, which is arranged along the axial direction of the column 300, and the driving rod 610 is connected with the corresponding support 430.

[0076] In these embodiments, since all the supports 430 connected with the same driving assembly 600 are arranged along the axial direction of the column 300 in sequence, the driving rod 610 can drive all the supports 430 to rotate around the rotation axis at the same time, ensuring the synchronization of the movement of all the supports 430 and improving the work efficiency. The driving rod 610 is arranged along the axial direction of the column 300, so that the structure of the whole driving assembly 600 is more compact, the space occupation is reduced, and more positioning assemblies 400 can be arranged in a limited space. By connecting multiple supports 430 with one driving rod 610, the number of parts of the driving assembly 600 is reduced, the overall structure of the tooling is simplified, and the manufacturing and maintenance costs are reduced.

[0077] Obviously, the driving rod 610 can quickly and accurately adjust the support 430 to the required position, reducing the assembly time and complexity. The operator only needs to start the driving assembly 600 to complete the positioning of the support 430, simplifying the assembly steps and improving the work efficiency.

[0078] In some embodiments, among the driving rod 610 and the support 430 connected with each other, the outer wall of the mounting sleeve 410 has a hinge part 420, the hinge part 420 has a second clamping groove 422 and a hinge hole 421 away from one end of the mounting sleeve 410, the extension direction of the second clamping groove 422 is parallel to the cross section of the column 300, the hinge hole 421 penetrates through the hinge part 420, and the second clamping groove 422 and the hinge hole 421 are arranged in cross, one end of the support 430 is arranged in the second clamping groove 422, the driving rod 610 is arranged in the hinge hole 421, the driving rod 610 and the hinge hole 421 are rotationally matched, the axis of the driving rod 610 coincides with the rotation axis, and the driving rod 610 is connected with the support 430.

[0079] In these embodiments, the extension direction of the second clamping groove 422 is parallel to the cross section of the column 300, ensuring that the support 430 can be accurately aligned during installation. The second clamping groove 422 can accommodate one end of the support 430, providing a stable initial position. The hinge hole 421 penetrates through the hinge part 420 and is arranged in cross with the second clamping groove 422, ensuring that the connection point of the support 430 and the driving rod 610 is fixed and reliable. For example, the extension directions of the hinge hole 421 and the second clamping groove 422 are arranged in perpendicular, and the axis of the hinge hole 421 is parallel to the axis of the column 300.

[0080] The driving rod 610 is arranged in the hinge hole 421 and rotationally cooperates with the hinge hole 421, so that the driving rod 610 can rotate freely in the hinge hole 421. The axis of the driving rod 610 coincides with the rotation axis of the support 430, so that the driving rod 610 can accurately drive the support 430 to rotate around the rotation axis. The combined design of the second clamping groove 422 and the hinge hole 421 provides multi-point contact, so that the support 430 can be kept stable during rotation and the shaking and deviation are reduced. The combined design of the second clamping groove 422 and the hinge hole 421 provides double support, so that the stability and reliability of the support 430 in different directions are ensured.

[0081] The connection between the hinge part 420 and the support 430 can be designed as a detachable or replaceable module, so that the adjustment and replacement can be facilitated according to different assembly requirements.

[0082] Optionally, the number of the hinge parts 420 is plural. In the embodiment, the number of the supports 430 is three, and the number of the hinge parts 420 is three. Of course, in other embodiments, the number of the supports 430 is four, and the number of the hinge parts 420 is four. Alternatively, the number of the supports 430 is five, and the number of the hinge parts 420 is five.

[0083] In some embodiments, the connection between the driving rod 610 and the support 430 is designed as a detachable connection.

[0084] In these embodiments, the above arrangement facilitates the assembly between the driving rod 610 and the support 430.

[0085] For example, the driving rod 610 is provided with a first pin hole, the support 430 is provided with a second pin hole, the first pin hole and the second pin hole are coaxially arranged, and a positioning pin is arranged in the first pin hole and the second pin hole, so as to realize the detachable connection between the driving rod 610 and the support 430.

[0086] In some embodiments, the driving assembly 600 further comprises a handle 630 and an adjusting sleeve 620. The handle 630 is connected to one end of the driving rod 610 away from the reference surface 110. The adjusting sleeve 620 is sleeved on the driving rod 610.
