Description

Technical Field

[0001] The utility model relates to the field related to motor maintenance, in particular to a device for removing stator coils of a motor. Background Art

[0002] After the stator coil of a small motor is burned out, it needs to be removed and replaced with a new coil. The current disassembly method is as follows: First, manually use a chisel and a hammer to cut off one end of the stator coil, and then use a crowbar and pliers to pull out the coil from the other end of the coil from the stator core. This is time-consuming and laborious, and there are burrs remaining at the root after manually cutting the stator coil, which is not conducive to subsequent pulling out.

[0003] The Chinese patent document with the publication number CN214591047U discloses a device for removing stator coils of a motor. The device fixes the motor stator on the installation base through a clamping member, manipulates the driving handle to rotate the driving lead screw, and at the same time drives the tangent support and the wire pulling support to move along the guide rail, so that the tangent knife on the tangent support is placed directly above the motor stator. By controlling the driving motor and the lifting motor, during the downward movement of the support arm, the tangent knife is driven to rotate by the driving shaft to cut off one end of the coil of the motor stator, thus facilitating the staff to remove the old coil.

[0004] However, in the original device, the distance between the clamping member and the tangent knife is very close, so that the staff needs to pay special attention to the distance between the product and the tangent knife to prevent the product and the tangent knife from colliding and contacting in advance due to an accident, resulting in damage to the product shell or deformation of the tangent knife due to impact. Therefore, there are still deficiencies in the placement structure of the original device. Summary of the Utility Model

[0005] Therefore, to solve the above deficiencies, the utility model provides a device for removing stator coils of a motor.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A device for removing the wire of a motor stator coil, comprising an operating table, a support frame, a lifting push cylinder, an installation box, an adjusting handle, an adjusting screw rod, an installation sliding arm, a wire removing knife machine, and a feeding device.

The driving push cylinder is drivingly connected to the left end of the installation slider. The installation slider is slidably connected to the top of the guiding slide rail. A storage box is arranged on the top of the installation slider. The guiding slide rail is fixed to the lower end inside the housing. The storage box is slidably connected to the top of the housing.

[0007] As a further scheme of the utility model, the storage box comprises a storage frame, a limiting plate, and a support block. The storage frame is fixed to the top of the support block. The limiting plate is arranged inside the storage frame. The support block is fixed to the top of the installation slider.

[0009] As a further scheme of the utility model, the driving push cylinder and the guiding slide rail are arranged horizontally in the housing at the same level.

[0010] As a further scheme of the utility model, there are two groups of guiding slide rails, and both groups of guiding slide rails are slidably matched with the bottom of the storage box.

DETAILED DESCRIPTION

[0023] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0024] See alsoFigure 1 and Figure 2 , in the embodiment of the present utility model:

[0025] A device for removing the wire of a motor stator coil, comprising an operating table 1, a support frame 2, a lifting push cylinder 3, an installation box 4, an adjusting handle 5, an adjusting lead screw 6, an installation sliding arm 7, a wire removing knife machine 8, and a feeding device 9. A support frame 2 is arranged on the top of the operating table 1. The lifting push cylinder 3 is installed on the top of the support frame 2. The lifting push cylinder 3 is slidably connected with the top of the installation box 4. The installation box 4 is slidably connected with the right end of the support frame 2. An adjusting handle 5 is installed at the right end of the installation box 4. The adjusting handle 5 is fixed to the right end of the adjusting lead screw 6. The adjusting lead screw 6 is rotatably connected with the inside of the installation box 4. The adjusting lead screw 6 is in threaded cooperation with the rear end of the installation sliding arm 7. The installation sliding arm 7 is slidably connected with the front end of the installation box 4. A wire removing knife machine 8 is installed at the bottom of the installation sliding arm 7. The feeding device 9 is fixed to the top of the operating table 1.

[0026] Reference Figure 3 and Figure 4 , in the embodiment of the present utility model:

[0027] The feeding device 9 comprises a housing 91, a driving push cylinder 92, an installation slider 93, a guiding slide rail 94, and a storage box 95. The housing 91 is fixed to the top of the operating table 1. The driving push cylinder 92 is installed inside the housing 91. The driving push cylinder 92 is in driving connection with the left end of the installation slider 93. The installation slider 93 is slidably connected with the top of the guiding slide rail 94. A storage box 95 is arranged on the top of the installation slider 93. The guiding slide rail 94 is fixed to the lower end inside the housing 91. The storage box 95 is slidably connected with the top of the housing 91.

[0028] Reference Figure 5 , in the embodiment of the present utility model:

[0029] The storage box 95 comprises a storage frame 951, a limiting plate 952, and a support block 953. The storage frame 951 is fixed to the top of the support block 953. The limiting plate 952 is arranged inside the storage frame 951. The support block 953 is fixed to the top of the installation slider 93.

[0030] Reference Figures 1 - 5, during use, place the operating table 1 horizontally on the ground so that the equipment can work stably. Place the motor to be maintained inside the storage frame 951 with the coil facing upwards, which facilitates the wire cutting machine 8 to cut the coil. Then, use the limiting plate 952 to hold the four corners of the motor to be maintained, thereby restricting the motor to be maintained inside the storage frame 951. Also, the support block 953 cooperates with the installation slider 93 to drive the motor to be maintained to move horizontally. By setting up the storage box 95 to place and restrict the motor to be maintained, the motor to be maintained can move along with the storage box 95. Start the transmission push cylinder 92 to pull the installation slider 93 to move inward, so that the installation slider 93 drives the storage box 95 to move under the restriction of the guiding slide rail 94 to the lower part of the installation box 4, which is convenient for cutting. Thus, it can be achieved that the feeding device 9 pushes the motor to be maintained to automatically move under the wire cutting machine 8, preventing the problem of accidental collision and contact during the process of placing the motor to be maintained, resulting in damage to the product shell or deformation of the tangent knife due to collision.

[0031] Furthermore, manually rotate the adjustment handle 5 to make the adjustment handle 5 drive the adjustment screw rod 6 to rotate, causing the adjustment screw rod 6 to move horizontally with the rear end of the installation sliding arm 7. When the installation sliding arm 7 moves to the upper position of the motor to be maintained, start the lifting push cylinder 3 to push the installation box 4 to move downward along the operating table 1, so that the installation sliding arm 7 can move along with the installation box 4. Then start the wire cutting machine 8 to cut the old coil, enabling the old coil to be quickly removed by the staff, effectively improving the work efficiency of the staff in replacing the coil.
