Description

Technical Field

[0001] The utility model relates to a turnover and transfer tool for super-large disc parts, belonging to the technical field of tooling fixtures. Background Art

[0002] The manufacturing of oversized disc-like parts presents numerous technical challenges in lifting and flipping due to their inherent structure and characteristics. These parts often lack excess stock, making it difficult to design lifting holes and process-aiding structures, posing significant challenges to transfer and flipping operations.

[0003] On the one hand, the impeller blades of the parts are high and easy to deform. During the conventional flipping and transportation process, the external force exerted by the lifting ropes and ground supports can easily cause the blades to deform, affecting the processing accuracy and final quality of the parts. On the other hand, the parts are heavy and have smooth surfaces, making them difficult to fix stably. The traditional lifting and flipping method is not only inefficient, but also has safety hazards caused by unstable fixation.

[0004] In addition, during conventional flipping operations, if the position of the lifting holes is not designed properly, when flipping to a critical angle (such as 90°), it is easy to cause an instantaneous flip due to inertia due to the shift in the center of gravity, which may cause damage to the lifting rope and lifting device, or even cause a safety accident; and if the center of gravity position is not handled properly, manual intervention may be required to assist in the flipping. For oversized parts, manual assistance is limited in effect and poses a great safety risk. Utility Model Content

DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] A tool for turning and transferring oversized disc parts, such as Figures 1-6 As shown, it includes a base plate 21, on which a fixing assembly 24 is provided for fixing the part 1 from the middle and / or the edge. A plurality of supporting legs 22 are provided on the periphery of the base plate 21, and the plurality of supporting legs 22 are respectively located on the lifting side and the flipping side. A lifting ring 23 is provided on the supporting leg 22 on the lifting side, and the supporting leg 22 on the flipping side has an arcuate edge 221 facing the flipping side, and the middle part of the arcuate edge 221 has a straight line segment, which is perpendicular to the base plate 21.

[0029] The base plate 21 serves as the basic load-bearing structure of the tooling, bearing the weight of the part 1 and other components, and providing a stable installation platform for the fixing assembly 24, support legs 22, etc., ensuring the rigidity and stability of the overall structure of the tooling during lifting, flipping and transportation, and avoiding shaking or shifting of the part 1 due to an unstable foundation. The fixing assembly 24 is the core structure for achieving precise positioning and firm fixation of the part 1. It firmly fixes the part 1 on the base plate 21, effectively solving the fixation problem caused by the smooth surface and lack of lifting holes 222 of the super-large disc-like parts 1, and at the same time avoids the deformation of the blades caused by displacement of the part 1 during operation. The support legs 22 are divided into a lifting side and a flipping side, with clear division of labor. A lifting ring 23 is provided on the support leg 22 on the lifting side, which is used to connect the lifting rope and the lifting device. By optimizing the relative position of the lifting point and the center of gravity, the risk of instantaneous inertial flipping caused by the shift of the center of gravity during flipping is avoided, ensuring safe operation. The support foot 22 on the flipping side has an arc-shaped structure designed towards the flipping side, which can reduce the friction resistance with the support surface during the flipping process, making the flipping trajectory of the part 1 smoother and improving the stability of the flipping operation. The straight section in the middle of the arc-shaped edge 221 is perpendicular to the base plate 21, providing a stable support surface when the part 1 is flipped to 90 degrees. When the flip is carried out to 90 degrees, the straight section perpendicular to the base plate 21 will form a rigid contact with the support surface, using its vertical characteristics to transmit a balanced support force, effectively offsetting the inertia during the lifting process, and preventing the part 1 from flipping instantly due to inertia. At the same time, it reserves time for the operator to adjust the position of the lifting ring 23 or the lifting rope to ensure that the flipping trajectory is smooth and controllable. The arc-shaped part ensures a smooth motion trajectory during flipping, while the middle straight section plays a stabilizing support role at the critical 90-degree position, protecting the blades from deformation caused by external impact. This solution is implemented through the fixing and lifting structure of the tooling, without relying on the lifting holes 222 of the part 1 itself. The blades are protected from deformation by external forces through the fixing components 24 and the support method. With the help of the optimized position of the lifting ring 23 and the design of the arc-shaped support foot 22, the problems of difficult fixing and high flipping safety risks caused by the heavy weight of the part 1 and the difficulty in controlling the center of gravity are resolved, and the safe and efficient flipping and transportation of the super-large disc-type parts 1 are achieved.

[0030] As another specific embodiment, the middle and lower parts and upper parts of the support leg 22 on the lifting side are both provided with lifting holes 222. When the part 1 is installed on the tooling, the middle and lower lifting holes 222 can be selected, which are closer to the center of the tooling, and can reduce the shift of the center of gravity toward the part 1 during flipping, avoid instantaneous flipping caused by the inertia of the center of gravity shift when flipping to 90°, and reduce the risk of damage to the lifting rope or lifting device; when the part 1 and the workpiece are turned upside down, the upper lifting holes 222 can be selected, which are relatively far away from the center. By utilizing the center of gravity transfer characteristics, the center of gravity will naturally switch to the other side when flipping to 90°, and the flipping can be completed without manual intervention, thereby improving operational safety. Preferably, the middle and lower parts of the support leg 22 on the flipping side are also provided with lifting holes 222. The lifting hole 222 in the lower middle part of the flip side support foot 22 is used in conjunction with the lifting hole 222 of the lifting side support foot 22 to meet the transfer requirements of super-large disc parts 1. There is no need to rely on the lifting hole 222 of the part 1 itself. Stable transfer can be achieved only through the cooperation of the lifting holes 222 on both sides of the tooling.

[0031] As another specific embodiment, the fixing assembly 24 includes a pressure plate 241 for pressing the part 1 from the center. The pressure plate 241 is detachably fixed to the center of the base plate 21 via a screw 242. The screw 242 realizes a detachable connection between the pressure plate 241 and the center of the base plate 21. By adjusting the tightness of the screw 242, it can adapt to parts 1 of different sizes or thicknesses, thereby improving the versatility of the tooling. Without relying on the part 1's own lifting holes 222 or process auxiliary structures, the tooling's built-in pressure plate 241 and screw 242 fixation method achieves a stable clamping; the center pressure prevents the blade from being deformed due to uneven force on the part 1; and the detachable design improves operational flexibility. Combined with the edge fixing method, for extra-large disc-like parts 1, the center pressure can balance the overall force on the part 1, avoiding warping or uneven force in the center of the part 1 caused by relying solely on edge fixing, thereby reducing indirect damage to the blade caused by deformation of the part 1.

[0032] As another specific embodiment, the screw rod 242 passes through the base plate 21, and a first nut 243 is provided at each end of the screw rod 242, one of the first nuts 243 being located above the pressure plate 241, and the other being located below the base plate 21. The first nut 243 located above the pressure plate 241 can directly adjust the degree of pressure of the pressure plate 241 on the part 1. When it is necessary to install or remove the part 1 from the top of the tooling, it is only necessary to loosen this nut to remove the pressure plate 241 and directly operate the part 1. The first nut 243 located below the base plate 21 is used to lock the relative position of the screw rod 242 and the base plate 21. When the workpiece is turned over and needs to be installed or removed from the bottom of the tooling, after loosening this nut, the screw rod 242 and the pressure plate 241 can be adjusted or removed as a whole, thereby ensuring the stability of the part 1 while maximally simplifying the two-sided operation process. This solution is a preferred method. When two-sided operation is not required, the screw 242 can be directly fixed to the base plate 21, and a thread is set on the pressure plate 241, which is fixed to the screw 242 through the thread; or only the first nut 243 is set above the pressure plate 241.

[0033] As another specific embodiment, the base plate 21 is provided in the middle of the support leg 22, and the support leg 22 is upwardly higher than the screw 242. The base plate 21 is provided in the middle of the support leg 22, so that the support leg 22 forms a symmetrical support structure from both sides of the base plate 21, ensuring that the base plate 21 and the part 1 fixed thereon are evenly stressed during the flipping and transportation process, avoiding tilting of the base plate 21 or shifting of the center of gravity of the part 1 due to support deflection, adapting to the heavy weight of the oversized disc-type part 1, and ensuring the stability of the overall structure. During the placement or flipping of the part 1, the support leg 22 will contact the support surface before the screw 242 and the pressure plate 241, avoiding damage caused by direct collision between the fixing assembly 24 and the support surface, and preventing the support surface from squeezing the screw 242 or the pressure plate 241 and indirectly affecting the fixed state of the part 1.

[0034] As another specific embodiment, the fixing assembly 24 includes multiple pressing blocks 244 for compressing the part 1 from the edge. The outer bottom of each pressing block 244 has a support block 245. The pressing block 244 is removably fixed to the base plate 21 via fixing bolts 246. The multiple pressing blocks 244 are used to apply a compressive force from the edge of the part 1, forming a coordinated compressive mode with the central pressure plate 241, further enhancing the stability of the fixed part 1 and preventing the edges of oversized disc-like parts 1 from warping or shifting during flipping and transportation due to their heavy weight and smooth surface. The support block 245 at the outer bottom of the pressing block 244 enhances the structural stability of the pressing block 244 during compression, preventing the pressing block 244 from deforming or tilting due to excessive force, and ensuring uniform and continuous pressure on the edge of the part 1. The fixing bolts 246 achieve a removable connection between the pressing block 244 and the base plate 21. During operation, the pressing block 244 can be installed and removed by simply loosening the nut.

[0035] As another specific embodiment, the fixing bolt 246 is provided with a second nut 247 after passing through the base plate 21. By clamping the fixing bolt 246 and the second nut 247 from the upper and lower sides of the base plate 21 respectively, the pressure block 244 can be effectively prevented from loosening during the vibration process of the part 1 being flipped and transported, ensuring that the clamping force on the edge of the part 1 is continuous and stable, and avoiding the displacement of the part 1 due to the loosening of the pressure block 244. When operating from above, the pressure block 244 can be removed by loosening the fixing bolt 246; when operating from below, it is only necessary to loosen the second nut 247 to cooperate with the fixing bolt 246 to adjust the state of the pressure block 244, without removing other components, and the operation path is not blocked. As a preferred solution, when two-sided operation is not required, threaded holes can be set on the base plate 21 and bolts can be used to directly connect to the threaded holes.

[0036] As another specific embodiment, the base plate 21 is provided with a radially extending strip-shaped hole 212, through which the fixing bolt 246 is installed. When the outer diameter or edge clamping position of an oversized disc-like part 1 varies, the fixing bolt 246 can move radially within the strip-shaped hole 212, thereby adjusting the position of the pressing block 244. This ensures that the pressing block 244 can precisely fit the edges of parts 1 of different specifications and exert effective clamping force. This eliminates the need to design separate fixing points for each size of part 1, thereby improving the adaptability of the tooling to parts 1 of various specifications.

[0037] As another specific embodiment, the base plate 21 is further provided with at least three circumferentially spaced positioning bolts 25. This multi-point support around the inner hole precisely defines the center position of the part 1 within the tooling, preventing radial displacement of the part 1 during transfer and flipping. Furthermore, the at least three positioning bolts 25 adhere to the stability principle of three-point positioning, ensuring that the part 1 is precisely centered within the corresponding positioning circle radius.

[0038] In another specific embodiment, the base plate 21 is provided with multiple groups of positioning holes 211, and the positioning bolts 25 are disposed within the positioning holes 211. Each group of positioning holes 211 includes at least three positioning holes, and each group of positioning holes 211 has a different positioning circle radius. The different positioning circle radiuses of each group of positioning holes 211 allow for the selection of matching groups of positioning holes 211 and the installation of positioning bolts 25 based on the varying inner hole sizes of oversized disk-like parts 1. This allows for the adaptation of parts 1 with various inner hole specifications, eliminating the need to design separate positioning structures for parts 1 of varying sizes.
