Description

Technical Field

[0001] The utility model relates to the technical field of rotary body assembly, and particularly relates to a docking assembly device for a rotary body. Background Art

[0002] In the field of contemporary manufacturing, due to the large size requirements of large rotary equipment, such equipment must be prefabricated in sections and then precisely docked and assembled on site. This process traditionally relies on a series of established steps: First, use heavy lifting machinery to hoist the independently manufactured rotary body segments to approximately docking positions; then, use traditional tools such as hydraulic jacks and adjustment pads to finely adjust the preset positions.

[0003] In the fine-tuning link, the rotary body is usually placed on a bearing seat and fixed by a clamp, and rotates relative to the clamp within the clamp for angle adjustment to achieve alignment of the docking surface. And in the existing docking process, the rotary body is usually finely adjusted and rotated by multiple people cooperating; however, this adjustment method introduces rotational errors due to the gap between the clamp and the rotary body, resulting in poor adjustment accuracy, and long-term relative rotation may cause wear at the contact part between the rotary body and the clamp, thereby affecting the smoothness and accuracy of rotation. Summary of the Utility Model

[0004] The utility model aims to provide a docking assembly device for a rotary body to improve the docking assembly accuracy of a large rotary body.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A docking assembly device for a rotary body includes a fixed base and a rotary docking mechanism. The rotary docking mechanism includes an adjustment mechanism and a supporting mechanism distributed from bottom to top. The bottom of the adjustment mechanism is slidably connected to the fixed base; the supporting mechanism is fixed on the top of the adjustment mechanism and includes a supporting seat and a fixed clamp. A rotation adjustment module is provided between the supporting seat and the fixed clamp. The rotation adjustment module includes a guide wheel, a gear and an arc-shaped rack that mesh with each other, and a driving motor for driving the gear to rotate. The arc-shaped rack is fixed on the fixed clamp.

[0006] The principle and advantages of this scheme are as follows:

[0007] 1. In actual application, in this scheme, the rotation adjustment module is arranged outside the fixed clamp, so that the fixed clamp and the rotary body rotate synchronously, reducing the relative friction between the two, improving the smoothness of rotation, and also avoiding the reduction of adjustment accuracy due to the gap between the two; moreover, the external placement of the rotation adjustment module enables fine adjustment of the rotation adjustment module independently without interfering with the docking operation, reducing the need to directly apply external force to the rotary body and protecting the structural integrity of the rotary body.

[0008] 2. Compared with the existing method of using tools such as jacks and adjusting pads and assisting manual fine-tuning during the docking and assembly process, in this solution, the arc rack is arranged on the fixed clamp, and the driving motor drives the gear to rotate, and through the meshing effect, the arc rack and the fixed clamp are driven to rotate for fine adjustment. This realizes automatic mechanical fine-tuning. The tight meshing of the gear and the arc rack not only ensures the smoothness and continuity of the slewing adjustment, but also through the motor drive, can perform fine-angle adjustments with extremely high precision, reducing the dependence on manual experience during the alignment process, and effectively improving the docking accuracy and efficiency.

[0009] 3. In this solution, the arc rack meshes with the gear to fix and limit the fixed clamp, effectively avoiding the need for readjustment due to secondary displacement caused by external forces after the slewing body is adjusted, saving human and material resources, effectively shortening the overall docking cycle of the slewing equipment, and saving costs.

[0010] Furthermore, the arc rack is fixed on the side of the fixed clamp, and the smooth surface of the arc rack is flush with the inner surface of the fixed clamp.

[0011] Fixing the arc rack on the side of the fixed clamp increases the contact area of the bottom of the fixed clamp for supporting the slewing body, improves the supporting stability of the slewing body, and the increased supporting area effectively reduces the pressure on the rotation adjustment module, reduces wear, and can better maintain the adjustment accuracy in the long term.

[0012] Furthermore, the fixed clamp includes an upper clamp and a lower clamp that are hinged to each other, and a rolling groove for the guide wheel to roll is provided on the outer ring of the lower clamp.

[0013] The cooperation between the rolling groove and the guide wheel realizes the rotation guidance of the fixed clamp, avoiding displacement deviation of the fixed clamp during the rotation of the slewing body and reducing the slewing docking accuracy.

[0014] Furthermore, the guide wheel includes a main guide wheel and a secondary guide wheel. The main guide wheel and the secondary guide wheel are fixedly connected to each other, and a receiving gap for accommodating the side of the lower clamp is provided between them.

[0015] The fixed clamp is limited by the receiving gap between the main guide wheel and the secondary guide wheel to prevent displacement deviation of the fixed clamp during rotation, effectively ensuring the accuracy of the slewing docking.

[0016] Furthermore, the adjustment mechanism includes a Z-direction adjustment unit, a Z-axis rotation adjustment unit, and an X-direction adjustment unit from bottom to top.

[0017] The above settings are for facilitating the adjustment of the slewing body in multiple degrees of freedom in three-dimensional space to improve the adjustment accuracy and efficiency.

[0018] Furthermore, an elastic anti-slip band is provided on the inner side of the fixed clamp.

[0019] The elastic anti-slip belt is used to avoid the direct contact between the rotating body and the fixed clamp, thereby avoiding rotational friction and wear. Secondly, the elastic anti-slip belt effectively ensures synchronous rotation between the rotating body and the fixed clamp, ensuring the adjustment accuracy of the rotating body.

[0020] Furthermore, the Z-direction adjustment unit, the Z-axis rotation adjustment unit, and the X-direction adjustment unit are all provided with manual operating rods.

[0021] Workers can roughly adjust each adjustment unit to zero through the manual operating rod to facilitate fixing the rotating body, which is beneficial to ensuring the accuracy of subsequent automatic alignment adjustment; secondly, the manual operating rod is convenient for workers to perform daily maintenance on the equipment.

[0026] The following is a more detailed description through specific embodiments:

[0027] The reference numerals in the accompanying drawings of the specification include: fixed base 1, slide rail 2, slider 3, rotary docking mechanism 4, adjustment mechanism 41, Z-direction adjustment unit 411, Z-axis rotation adjustment unit 412, X-direction adjustment unit 413, supporting mechanism 42, supporting seat 421, arc-shaped guide groove 4211, trapezoidal base 4212, fixed clamp 422, upper clamp 4221, lower clamp 4222, rolling groove 4223, rotation adjustment module 43, main guide wheel 431, auxiliary guide wheel 432, arc-shaped rack 433, gear 434, drive motor 435, support plate 5, manual operating rod 6.

[0028] The embodiment is basically as shown in the attached Figures 1-4As shown in the figure: A docking and assembling device for a rotating body, including a fixed base 1, a rotating docking mechanism 4 and a controller. The rotating docking mechanism 4 is signal-connected to the controller, and the controller is a PLC of the prior art. The rotating docking mechanism 4 includes an adjusting mechanism 41 and a supporting mechanism 42 distributed from bottom to top. A slide rail 2 is provided at the top of the fixed base 1. A slider 3 is provided at the bottom of the adjusting mechanism 41. The slider 3 is matched with the slide rail 2 to realize the sliding connection between the adjusting mechanism 41 and the fixed base 1, that is, the Y-direction adjustment of the rotating body. The adjusting mechanism 41 includes a Z-direction adjusting unit 411, a Z-axis rotating adjusting unit 412 and an X-direction adjusting unit 413 from bottom to top. Each adjusting unit is signal-connected to the controller. In specific applications, each adjusting unit of the adjusting mechanism 41 is started to realize the multi-degree-of-freedom adjustment of the rotating body.

[0029] The supporting mechanism 42 is fixed on the top of the adjusting mechanism 41. The supporting mechanism 42 includes a supporting seat 421 and a fixed clamp 422. The supporting seat 421 includes a trapezoidal base 4212 and an arc-shaped guide groove 4211, which are integrally formed. The fixed clamp 422 includes an upper clamp 4221 and a lower clamp 4222 that are hinged to each other. A rotation adjustment module 43 is provided between the supporting seat 421 and the fixed clamp 422. The rotation adjustment module 43 includes a guide wheel, a gear 434 and an arc-shaped rack 433 that mesh with each other, and a driving motor 435 that drives the gear 434 to rotate. A rolling groove 4223 is provided on the outer ring of the lower clamp 4222. The guide wheel rotates between the arc-shaped guide groove 4211 and the rolling groove 4223. The arc-shaped rack 433 is fixed on the fixed clamp 422. Preferably, in this embodiment, the arc-shaped rack 433 is fixed on one side of the fixed clamp 422, and the smooth surface of the arc-shaped rack 433 is flush with the inner surface of the fixed clamp 422. In this way, the contact area between the fixed clamp 422 and the rotating body can be effectively increased, the supporting stability of the rotating body is improved, and the increased supporting area effectively reduces the load pressure on the rotation adjustment module 43, thereby reducing wear and maintaining the long-term rotation adjustment accuracy. The driving motor 435 is fixed on the side of the supporting seat 421. The driving motor 435 is a servo forward and reverse motor. The driving motor 435 is signal-connected to the controller. The trapezoidal base 4212 is hollow inside and communicates with the arc-shaped guide groove 4211 to accommodate the gear 434. An installation hole is provided on one side of the supporting seat 421. The output shaft of the driving motor 435 passes through the installation hole and is connected and fixed to the gear 434.

[0030] Preferably, the guide wheel includes a main guide wheel 431 and a sub-guide wheel 432. The main guide wheel 431 and the sub-guide wheel 432 are fixedly connected, and there is an accommodation gap between them for accommodating the side of the lower clamp 4222. The main guide wheel 431 is located in the rolling groove 4223. The main guide wheel 431 and the sub-guide wheel 432 are designed to limit the fixed clamp 422 by using the accommodation gap while ensuring the rotation of the fixed clamp 422, preventing displacement deviation of the fixed clamp 422 during rotation, and effectively ensuring the accuracy of rotary docking.

[0031] An elastic anti-slip belt (not shown in the figure) is provided on the inner side of the fixed clamp 422. The elastic anti-slip belt is a rubber belt and conforms to the shape of the inner side of the fixed clamp 422. By means of the elastic anti-slip belt, the rotary body is prevented from directly contacting the fixed clamp 422, thereby avoiding rotational friction and wear. Secondly, the elastic anti-slip belt effectively ensures synchronous rotation between the rotary body and the fixed clamp 422, ensuring the adjustment accuracy of the rotary body.

[0032] Through the above settings, in this solution, the rotation adjustment module 43 is arranged outside the fixed clamp 422, enabling the fixed clamp 422 and the rotary body to rotate synchronously, reducing the relative friction and existing gaps between the two, and improving the smoothness of rotation and docking accuracy. Secondly, in this solution, the arc-shaped rack 433 is arranged on the fixed clamp 422, and the drive motor 435 drives the gear 434 to rotate and meshes with it to drive the arc-shaped rack 433 and the fixed clamp 422 to rotate for fine adjustment. This realizes automatic mechanical fine adjustment. The close meshing of the gear 434 and the arc-shaped rack 433 not only ensures the smoothness and continuity of rotary adjustment, but also, through motor drive, can execute fine angle adjustments with extremely high precision, reducing the dependence on manual experience during the alignment process, effectively improving the docking accuracy and efficiency. Moreover, the meshing of the arc-shaped rack 433 and the gear 434 fixes and limits the fixed clamp 422, effectively preventing the rotary body from generating secondary displacement due to external forces after adjustment and requiring readjustment, saving human and material resources, effectively shortening the overall docking cycle of the rotary equipment, and saving costs.

[0033] Support plates 5 are provided between the adjustment units of the adjustment mechanism 41, between the slider 3 and the Z-direction adjustment unit 411, and between the X-direction adjustment unit 413 and the support seat 421. Among them, the Z-direction adjustment unit 411, the Z-axis rotation adjustment unit 412, and the X-direction adjustment unit 413 are all prior arts, which are respectively a screw jack, an electric rotary table, and a ball screw pair cooperating with a slider rail, and will not be elaborated here; to ensure that the adjustment mechanism 41 can still operate when a failure occurs in the automatic control part of the adjustment mechanism 41 or maintenance is required, each adjustment unit is provided with a manual operation rod 6. Workers can roughly adjust each adjustment unit to zero through the manual operation rod 6 to facilitate fixing the rotating body, and it is beneficial to ensure the accuracy of subsequent automatic alignment adjustment; secondly, the manual operation rod 6 facilitates workers to perform daily maintenance on the equipment.
