Description

Technical Field

[0001] The utility model belongs to the technical field of motor manufacturing, and specifically relates to a turnover device for a motor iron core. Background Technique

[0002] During the production process of a motor iron core, it is often necessary to perform multiple turnovers and hoists to complete various processing steps and assembly processes. It is necessary to turn the stator and rotor iron cores from a lying state to an upright state or from an upright state to a lying state. Due to the complex structure, large weight and irregular shape of the iron core, there are certain operation difficulties and potential safety hazards during the turnover and hoist processes.

[0003] In the prior art, the turnover and hoist of the rotor iron core are mainly carried out by bundling the outer circle of the iron core with a wire rope sling. Although this method is simple, since the outer circle of the iron core is smooth, when the wire rope sling hoists in the vertical state, it mainly relies on friction to bear the weight of the iron core. The bearing capacity of this friction is limited. Especially during the hoist and turnover process, the relative sliding between the wire rope and the iron core easily causes the iron core to slip, posing a large potential safety hazard. Content of the Utility Model

[0004] The purpose of the utility model is to provide a turnover device for a motor iron core to solve the problems raised in the above-mentioned prior art.

[0005] Provide a turnover device for a motor iron core, including a frame. A turnover frame body is arranged above the frame. The turnover frame body is rotationally connected to the frame. A turnover mechanism for driving the turnover frame body to rotate is arranged on one side of the lower part of the frame.

[0006] A V-shaped support mechanism is arranged above the turnover frame body. Pressing mechanisms are also arranged on both sides of the turnover frame body. A plane support mechanism is arranged on one side of the turnover frame body away from the V-shaped support mechanism.

[0007] As a further embodiment of the utility model: The turnover mechanism includes a turnover oil cylinder. The turnover oil cylinder is arranged on the frame. The telescopic end of the turnover oil cylinder is fixedly connected with a connecting rib plate. The turnover frame body is fixedly connected to the connecting rib plate. The turnover frame body is rotationally connected above the frame through a rotating shaft. When the turnover oil cylinder expands and contracts, the connecting rib plate drives the turnover frame body to rotate around the rotating shaft, which will drive the connecting rib plate and the turnover frame body to move together to realize the turnover of the iron core.

[0008] As a further embodiment of the present utility model: The V-shaped support mechanism includes two first guide rails, which are symmetrically arranged on the flipping frame body. A V-shaped support table is slidably connected between the two first guide rails. One side of the upper part of the V-shaped support table is provided with a pushing oil cylinder, which is arranged on one side of the upper part of the flipping frame body. The pushing oil cylinder is used to push the entire V-shaped support table to slide along the direction of the first guide rail, so as to adjust the position of the V-shaped support table to adapt to iron cores in different states. The pushing oil cylinder pushes the entire V-shaped support table to move, making the iron core move away from or close to the planar support mechanism, so as to facilitate subsequent hoisting and flipping operations.

[0009] As a further embodiment of the present utility model: Both sides of the upper part of the V-shaped support table are provided with first wear-resistant copper plates, which can effectively reduce the friction between the iron core and the V-shaped support table during the flipping process.

[0010] As a further embodiment of the present utility model: The pressing mechanism includes a pressing oil cylinder, which is arranged on one side of the upper part of the flipping frame body. The telescopic end of the pressing oil cylinder is connected with a pressing rod, and the pressing rod is rotatably connected to a support rod. The support rod is arranged on the flipping frame body. The pressing oil cylinder controls the rotation of the pressing rod on the support rod through the action of the telescopic end, adjusts the position of the pressing rod, and makes the two side pressing rods tightly fit on the outer walls of both sides of the iron core, ensuring that the iron core will not move or fall off during the flipping process. When it is loose, the rotation of the pressing rod on the support rod is controlled again by adjusting the action of the telescopic end of the pressing oil cylinder, so that the two side pressing rods no longer tightly fit on the outer walls of both sides of the iron core.

[0011] As a further embodiment of the present utility model: Second wear-resistant copper plates are arranged on the upper parts of the pressing rods, which can effectively reduce the friction between the iron core and the pressing rods during the clamping process.

[0012] As a further embodiment of the present utility model: The planar support mechanism includes a planar support table, a second guide rail, a third guide rail, an upper-layer oil cylinder, a lower-layer oil cylinder and a planar support plate. The lower-layer oil cylinder is arranged on one side of the upper part of the flipping frame body. The telescopic end of the lower-layer oil cylinder is fixedly connected with the planar support plate, and the planar support plate is slidably connected to the second guide rail. The second guide rail is fixedly connected to the flipping frame body. A third guide rail is arranged on the planar support plate, and the planar support table is slidably connected to the third guide rail. One side of the upper part of the planar support table is provided with an upper-layer oil cylinder, and the telescopic end of the upper-layer oil cylinder is fixedly connected with the planar support table. The telescopic movement of the lower-layer oil cylinder drives the planar support plate to move along the second guide rail, thereby adjusting the distance between the entire planar support table and the V-shaped support table. The telescopic movement of the upper-layer oil cylinder drives the entire planar support table to move along the third guide rail, thereby adjusting the distance between the center positions of the entire planar support table and the V-shaped support table, facilitating the placement of the iron core. The position of the planar support table can be adjusted as needed.

[0013] As a further embodiment of the present utility model: a hydraulic station is provided on one side of the upper part of the frame, and through the pressure adjustment of the hydraulic station, precise control of the actions of each hydraulic cylinder (such as the tipping cylinder, pressing cylinder, upper layer cylinder, lower layer cylinder) is achieved.

[0014] As a further embodiment of the present utility model: lifting lugs are also provided on both sides of the upper part of the frame for lifting the entire tipping device.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The iron core is turned from horizontal to vertical. The lifted iron core is placed above the V-shaped support mechanism. The two sides of the iron core to be turned are pressed by the pressing mechanisms on both sides of the tipping frame body. The specific position of the entire V-shaped support mechanism is adjusted until one side of the iron core contacts one side of the planar support mechanism. Then, the tipping mechanism is controlled again to rotate and turn by 90° until the bottom side of the iron core is placed on the planar support mechanism, completing the turning of the iron core. The pressing mechanisms no longer press the two sides of the iron core that has been turned. The turned iron core is lifted by the subsequent lifting device.

[0017] The iron core is turned from vertical to horizontal. The entire tipping frame is adjusted by the tipping mechanism, and the position of the V-shaped support mechanism is adjusted to be away from the planar support mechanism. After being away, the entire iron core is lifted above the entire planar support mechanism. The position of the planar support mechanism is adjusted again to make the iron core contact the V-shaped support mechanism. The two sides of the iron core to be turned are pressed by the pressing mechanisms on both sides of the tipping frame body. Then, the tipping mechanism is controlled again to rotate and turn by 90° until the outer wall of the iron core is placed above the V-shaped support mechanism, completing the turning of the iron core. The position of the V-shaped support mechanism is adjusted again to be away from the planar support mechanism. The pressing mechanisms no longer press the two sides of the iron core that has been turned. The turned iron core is lifted by the subsequent lifting device.

[0018] Through the operation of the above two states, the iron core can be turned from vertical to horizontal or from horizontal to vertical. The turning of the iron core is convenient. During the turning process of the iron core, the pressing mechanisms are used for limiting and fixing. When using this tipping mechanism to turn the iron core, it can avoid the phenomenon that the iron core slips due to the relative sliding between the steel wire rope and the iron core during the process of lifting and turning the iron core with the steel wire rope, eliminating the potential safety hazard during the turning process of the iron core.

[0028] However, there may be cases where unnecessary detailed descriptions are omitted. For example, there are cases where detailed descriptions of well-known matters are omitted and repeated descriptions of actually identical structures are omitted. This is to prevent the following descriptions from becoming unnecessarily lengthy and to facilitate the understanding of those skilled in the art. In addition, the accompanying drawings and the following descriptions are provided for those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0029] Please refer to Figures 1-5 As shown, in an embodiment of the present utility model, a turnover device for a motor core includes a frame 1. Above the frame 1, a turnover frame body 2 is provided. The turnover frame body 2 is rotatably connected to the frame 1. On one side of the lower part of the frame 1, a turnover mechanism 3 for driving the turnover frame body 2 to rotate is provided;

[0030] Above the turnover frame body 2, a V-shaped support mechanism 4 is provided. The V-shaped support mechanism 4 is used to support the core 7, for adjusting the end face of the core 7 to contact the flat support mechanism 6, or for adjusting the core 7 from the contact state to a state away from the flat support mechanism 6, so as to facilitate the lifting and transportation of the core 7. On both sides of the turnover frame body 2, a pressing mechanism 5 is further provided. The pressing mechanism 5 is used to press both sides of the core 7 to prevent the core 7 from falling off during the turnover process. On one side of the turnover frame body 2 away from the V-shaped support mechanism 4, a flat support mechanism 6 is provided for adjusting the position of the core 7 during the turnover process;

[0031] In a specific embodiment, the turnover process of the core 7 is as follows. The core 7 is turned from a horizontal position to a vertical position (i.e., from Figure 1 turned to Figure 5 state). The entire V-shaped support mechanism 4 is adjusted to a horizontal state through the turnover mechanism 3. The core 7 is lifted and placed above the V-shaped support mechanism 4. The pressing mechanism 5 on both sides of the turnover frame body 2 presses both sides of the core 7 to be turned over. The specific position of the entire V-shaped support mechanism 4 is adjusted until one side of the core 7 contacts one side of the flat support mechanism 6. Then, the turnover mechanism 3 is controlled to rotate by 90° again until the bottom side of the core 7 is placed on the flat support mechanism 6 (i.e., the core 7 is turned from a horizontal position to a vertical position), completing the turnover of the core 7. The pressing mechanism 5 no longer presses both sides of the core 7 that has been turned over, and the core 7 is lifted and transported by a subsequent lifting device;

[0032] In another working state process, the core 7 is turned from a vertical position to a horizontal position (i.e., from Figure 5 turned to Figure 1In the state of (), the entire flipping frame 2 is adjusted by the flipping mechanism 3 so that the entire planar support mechanism 6 is in a horizontal state and parallel to the frame 1, while the V-shaped support mechanism 4 is perpendicular to the plane of the frame 1. The position of the V-shaped support mechanism 4 is adjusted away from the planar support mechanism 6. After the adjustment is completed, the entire iron core 7 is lifted and placed above the entire planar support mechanism 6. Then, the position of the planar support mechanism 6 is adjusted again so that the iron core 7 contacts the V-shaped support mechanism 4. The two sides of the iron core 7 to be flipped are clamped by the clamping mechanisms 5 on both sides of the flipping frame 2. Then, the flipping mechanism 3 is controlled to rotate and flip by 90° until the outer wall of the iron core 7 is placed above the V-shaped support mechanism 4, completing the flipping of the iron core 7 (i.e., flipping the iron core 7 from the vertical position to the horizontal position). The position of the V-shaped support mechanism 4 is adjusted again to be away from the planar support mechanism 6, and the clamping mechanism 5 no longer clamps the two sides of the iron core 7 that has been flipped. The iron core 7 that has been flipped is lifted by the subsequent lifting device;

[0033] Through the operation of the above two states, the iron core 7 can be flipped from the vertical position to the horizontal position or from the horizontal position to the vertical position. The flipping of the iron core 7 is convenient. During the flipping process of the iron core 7, the clamping mechanism 5 is used for limiting and fixing. When using this flipping mechanism 3 to flip the iron core 7, it can avoid the phenomenon that the iron core 7 slips due to the relative sliding between the steel wire rope and the iron core 7 during the process of flipping the iron core 7 by using the steel wire rope for lifting, eliminating the potential safety hazard during the flipping process of the iron core 7.

[0034] In a further embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the flipping mechanism 3 includes a flipping oil cylinder 31. The flipping oil cylinder 31 is arranged on the frame 1. The telescopic end of the flipping oil cylinder 31 is fixedly connected with a connecting rib plate 32. The connecting rib plate 32 is fixedly connected with a flipping frame 2. The flipping frame 2 is rotatably connected above the frame 1 through a rotating shaft 33. When the flipping oil cylinder 31 expands and contracts, the connecting rib plate 32 drives the flipping frame 2 to rotate around the rotating shaft 33, which will drive the connecting rib plate 32 and the flipping frame 2 to move together to realize the flipping of the iron core 7.

[0035] In a further embodiment, please refer to Figure 1 、 Figure 2 and Figure 3As shown in the figure, the V-shaped support mechanism 4 includes two first guide rails 41, which are symmetrically arranged on the flipping frame 2. A V-shaped support table 42 is slidably connected between the two first guide rails 41. The V-shaped support table 42 is used to support the iron core 7. On one side of the upper part of the V-shaped support table 42, a pushing oil cylinder 43 is arranged. The pushing oil cylinder 43 is arranged on one side of the upper part of the flipping frame 2. The pushing oil cylinder 43 is used to push the entire V-shaped support table 42 to slide along the direction of the first guide rail 41, so as to adjust the position of the V-shaped support table 42 to adapt to the iron core 7 in different states. During the process of the iron core 7 being flipped from the horizontal position to the vertical position, the iron core 7 is lifted and placed on the V-shaped support table 42. The V-shaped support table 42 provides stable support for the iron core 7 to prevent the iron core 7 from tilting or moving during the flipping process. When it is necessary to adjust the position of the iron core 7 or move the iron core 7 away from the planar support mechanism 6, the pushing oil cylinder 43 pushes the entire V-shaped support table 42 to move, so that the iron core 7 moves away from or approaches the planar support mechanism 6, facilitating subsequent lifting and flipping operations.

[0036] Furthermore, in one embodiment, please refer to Figure 1 、 Figure 2 and Figure 4 As shown in the figure, first wear-resistant copper plates 44 are arranged on both sides of the upper part of the V-shaped support table 42. The first wear-resistant copper plates 44 can effectively reduce the friction between the iron core 7 and the V-shaped support table 42 during the flipping process.

[0037] In one embodiment, please refer to Figure 1 and Figure 2 As shown in the figure, the pressing mechanism 5 includes a pressing oil cylinder 51. The pressing oil cylinder 51 is arranged on one side of the upper part of the flipping frame 2. The telescopic end of the pressing oil cylinder 51 is connected with a pressing rod 52. The pressing rod 52 is rotatably connected to a support rod 53. The support rod 53 is arranged on the flipping frame 2. The pressing oil cylinder 51 controls the rotation of the pressing rod 52 on the support rod 53 through the action of the telescopic end, adjusts the position of the pressing rod 52, so that the two pressing rods 52 are tightly pressed against the outer walls on both sides of the iron core 7, ensuring that the iron core 7 does not move or fall off during the flipping process. When it is loose, the action of the telescopic end of the pressing oil cylinder 51 is adjusted again to control the rotation of the pressing rod 52 on the support rod 53, so that the two pressing rods 52 are no longer tightly pressed against the outer walls on both sides of the iron core 7.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 As shown in the figure, second wear-resistant copper plates 54 are arranged on the upper parts of the pressing rods 52. The second wear-resistant copper plates 54 can effectively reduce the friction between the iron core 7 and the pressing rods 52 during the clamping process.

[0039] In one embodiment, please refer to Figure 1 and Figure 2As shown in the figure, the planar support mechanism 6 includes a planar support platform 61, a second guide rail 62, a third guide rail 63, an upper layer oil cylinder 64, a lower layer oil cylinder 65, and a planar support plate 66. The lower layer oil cylinder 65 is arranged on one side of the upper part of the overturning frame body 2. The telescopic end of the lower layer oil cylinder 65 is fixedly connected with the planar support plate 66. The planar support plate 66 is slidably connected to the second guide rail 62. The second guide rail 62 is fixedly connected to the overturning frame body 2. A third guide rail 63 is arranged on the planar support plate 66. The planar support platform 61 is slidably connected to the third guide rail 63. An upper layer oil cylinder 64 is arranged on one side of the upper part of the planar support platform 61. The telescopic end of the upper layer oil cylinder 64 is fixedly connected with the planar support platform 61. The telescopic movement of the lower layer oil cylinder 65 drives the planar support plate 66 to move along the second guide rail 62, thereby adjusting the distance between the entire planar support platform 61 and the V-shaped support platform 42. The telescopic sliding movement of the upper layer oil cylinder 64 drives the entire planar support platform 61 to move along the third guide rail 63, thereby adjusting the distance between the entire planar support platform 61 and the central position of the V-shaped support platform 42, facilitating the placement of the iron core 7.

[0040] In one embodiment, please refer to Figure 1 and Figure 2 As shown in the figure, a hydraulic station is arranged on one side of the upper part of the frame 1. Through the pressure adjustment of the hydraulic station, precise control over the actions of each hydraulic cylinder (such as the overturning oil cylinder 31, the pressing oil cylinder 51, the upper layer oil cylinder 64, and the lower layer oil cylinder 65) is achieved.

[0041] In one embodiment, please refer to Figure 1 and Figure 2 As shown in the figure, lifting lugs 11 are further arranged on both sides of the upper part of the frame 1 for lifting the entire overturning device.
