Description

Technical Field

[0001] The utility model relates to the technical field of drum motor manufacturing, in particular to a stator turning device in a drum. Background Art

[0002] The operation process of the drum inner stator is to place the inner stator bracket horizontally on the bracket and carry out the coil embedding process. After the embedding process is completed, the inner stator bracket needs to be hoisted to the vertical direction by a crane to further complete the varnishing and pouring process. After the varnishing and pouring are completed, the inner stator bracket needs to be adjusted from the vertical direction to the horizontal direction to complete the operation of the next process.

[0003] The existing hoisting scheme is: install the flip rings in the threaded holes on both sides of the drum motor shaft, use the main hook and auxiliary hook of the trolley to hang the flip rings respectively, with the auxiliary hook downward and the main hook upward, and slowly flip the inner stator bracket to the vertical direction. This flipping scheme simply relies on the trolley, which cannot guarantee personal safety, and the operation is complicated and non-standard, which is easy to cause damage to the motor shaft of the inner stator bracket. Utility Model Content

[0006] A flip support frame, used to support the flipping of the inner stator bracket;

[0009] A cylinder body, used to support the inner stator motor shaft;

[0010] A support shaft, one end of which is connected to the cylinder and the other end of which extends into the bearing seat to achieve the turning of the cylinder;

[0011] The baffle is connected to the end surface of the cylinder and supports the stator motor shaft in the vertical direction.

[0012] Furthermore, it also includes a wooden support, and a positioning groove is provided on the top of the wooden support for auxiliary support of the inner stator during the turning process.

[0013] Furthermore, angle plates are provided between the support shaft and the cylinder, and a first screw hole is opened on each angle plate; fixing plates are provided on both sides of the inner wall of the flip support frame, and symmetrically arranged second screw holes and symmetrically arranged third screw holes are respectively opened on the fixing plates.

[0014] Furthermore, when the cylinder is flipped forward horizontally, the first screw hole corresponds to the second screw hole; when the cylinder is flipped backward horizontally, the first screw hole corresponds to the third screw hole.

[0015] Furthermore, the turning cylinder also includes a supporting screw, one end of which is connected to the first screw hole, and the other end of which is connected to the second screw hole or the third screw hole, for keeping the turning cylinder in a horizontal state.

[0016] Furthermore, a plurality of nylon sleeves with different inner diameters are arranged in the turning cylinder for positioning the inner stator motor shaft.

[0017] Furthermore, a handle is provided on the outer side of the baffle for manually turning up the cylinder.

[0018] Furthermore, the baffle is provided with through holes for cables to escape and cooling water to flow out.

[0019] As a further step, a fixing hole is provided on the bottom plate of the flip support frame for fixing the flip support frame on the ground or a workbench.

[0020] As a further step, reinforcing ribs are provided on both sides of the U-shaped plate of the flip support frame.

[0021] Compared with the prior art, the above technical solution adopted by the utility model has the following advantages: the flipping device is used to flip the inner stator bracket in a horizontal state after the wire embedding process to a vertical state required for paint dipping. After the pouring process is completed, the inner stator bracket can be flipped from a vertical state to a horizontal state using a flipping tool to continue to complete the processes such as motor lead arrangement. The problem that the inner stator coil and vertical materials are easily damaged when the inner stator bracket is flipped is solved. The flipping tool has a simple structure, is easy to operate, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Please refer to 1- Figure 5 This embodiment provides a stator turning device in a drum, comprising:

[0034] The flip support frame is used to support the flipping of the inner stator bracket; it includes a bottom plate and a U-shaped plate, the bottom plate is provided with a plurality of fixing holes for fixing the flip support frame on the ground or a workbench; the notch of the U-shaped plate is used to avoid the flip cylinder, and reinforcing ribs are provided on both sides of the U-shaped plate, and the reinforcing ribs are located on the bottom plate;

[0035] The bearing seat is symmetrically fixed on the flip support frame by bolts and nuts to realize the flipping of the inner stator bracket;

[0036] A wooden support with a positioning groove on the top for auxiliary support of the inner stator during the flipping process;

[0037] The turning cylinder is connected between the bearing seats to ensure the stability of the inner stator bracket during the turning process; the turning cylinder includes:

[0038] The cylinder is used to support the inner stator motor shaft to ensure that the motor shaft does not shift laterally during the flipping process;

[0039] A support shaft, one end of which is connected to the cylinder and the other end of which extends into the bearing seat to achieve the turning of the cylinder;

[0040] The baffle is connected to the end face of the cylinder and supports the stator motor shaft in the vertical direction. A handle is provided on the outside of the baffle for manually flipping up the cylinder, and a through hole is provided on the baffle for cable avoidance and cooling water outflow.

[0041] As a preferred implementation scheme provided in this embodiment, angle plates are provided between the support shaft and the cylinder body, and a first screw hole is opened on each angle plate; fixed plates are provided on both sides of the inner wall of the flip support frame, and symmetrically arranged second screw holes and symmetrically arranged third screw holes are respectively opened on the fixed plates; when the cylinder body is flipped forward horizontally, the first screw hole corresponds to the second screw hole; when the cylinder body is flipped backward horizontally, the first screw hole corresponds to the third screw hole.

[0042] It should be noted here that the center of gravity of the cylinder 31 is not on the axis of the support shaft. The cylinder 31 is naturally vertical. When it is manually flipped to a horizontal state, a screw 34 is inserted into the second screw hole or the third screw hole to support and fix the cylinder 31 to keep it horizontal.

[0043] As a preferred implementation provided by this embodiment, a plurality of nylon sleeves with different inner diameters are provided in the turning cylinder, which can be suitable for motor shafts with different shaft diameters.

[0044] Specific implementation process: When the inner stator 4 is in a horizontal state, turn the cylinder 31 to a horizontal state, and insert the screw 34 into the first screw hole and the second screw hole or the third screw hole to ensure that the cylinder 31 is horizontal. Use a trolley to slowly guide one end of the inner stator motor shaft into the nylon sleeve 35. When the inner stator motor shaft contacts the baffle 33, pull out the screw 34, and use the trolley to lift the other end of the inner stator motor shaft until the inner stator 4 is in a vertical state; at this time, the residual water of the pressure test in the inner stator bracket can flow out through the through hole 33-2 to ensure that the bracket will not be frozen during winter transportation. Then use the trolley to lift the inner stator 4 in the vertical direction until it is separated from this device.

[0045] When the cylinder 31 is in a vertical state, the inner stator motor shaft is guided into the nylon sleeve 35 from above by a trolley until it contacts the baffle 33, and then the trolley is slowly lowered. One end of the inner stator motor shaft is fixed by the device, and the other end is flipped with the trolley until the inner stator 4 contacts the wooden support 5 and flips to a horizontal state. At this time, the screw 34 is inserted into the first screw hole and the second screw hole or the third screw hole to ensure the horizontal state of the flip cylinder, and then the inner stator motor shaft is slowly withdrawn by the trolley to complete the flip from vertical to horizontal direction.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
