Embodiment 1

[0022] like figure 1 As shown, the take-out device of the stator winding of the motor can be hydraulically driven to realize the left and right movement of the connecting rod 9, specifically, a drive device including an oil cylinder 12, a hydraulic pump 14 and an oil tank 15 can be used, and the oil cylinder 12 is arranged on the guide On the device 2, it is parallel to the connecting rod 9; the left end of the oil cylinder 12 is fixedly connected with the guide device 2, and is connected with the oil tank 15 through the hydraulic pump 14; the piston of the oil cylinder 12 is connected with the right end of the connecting rod 9 through the connecting plate 13.

[0023] When in use, after the stator winding 7 is hooked, the hydraulic pump 14 can be started, the piston of the oil cylinder 12 stretches out to the right under the action of oil pressure, and the connecting rod 9, the claw hook 8 and the stator winding 3 are driven by the connecting plate 13 Move to the right togeth...

Embodiment 2

[0025] like figure 2 As shown, the take-out device of the stator winding of the motor can be pneumatically driven to realize the left and right movement of the connecting rod 9, specifically, a driving device including a cylinder 10 and an air compressor 11 can be used, and the cylinder 10 is arranged on the guide device 2 above, parallel to the connecting rod 9; the left end of the cylinder 10 is fixedly connected to the guide device 2 and connected to the air compressor 11; the piston of the cylinder 10 is connected to the right end of the connecting rod 9 through the connecting plate 13.

[0026] During use, it is the same as the operation in embodiment 1, and the only difference is that it controls the expansion and contraction of the cylinder 10 by the opening and closing of the air compressor 11, and realizes the back and forth movement of the connecting rod 9 by means of the expansion and contraction of the piston in the cylinder 10, Then, the stator winding is pulled ...

Embodiment 3

[0032] like image 3 As shown, a device for taking out a motor stator winding is characterized in that it includes an underframe 1, a support 4, a stator fixing device 6, a guide rail bracket 17, a telescopic rod device 16 and a mounting bracket 18, and the underside of the underframe 1 Wheels 5 are installed; the stator fixing device 6, support member 4, rail bracket 17 and mounting bracket 18 are installed on the chassis 1 from left to right in turn; the telescopic rod device 16 is placed on the rail bracket 17, and the telescopic rod The left end of the device 16 is equipped with a hook 8 , and the right end is installed on the mounting bracket 18 ; the stator fixing device 6 includes a fixing bracket 61 and a chuck 62 installed on the fixing bracket 61 .

[0033] Preferably, the telescopic rod device 16 may use an electric telescopic rod, which is cheaper and more convenient to operate than a pneumatic telescopic rod or a hydraulic telescopic rod.

[0034] In the initial ...

Abstract

The invention discloses a device for extracting a stator winding of a generator. The device comprises a bottom rack (1), a guide device (2), a connecting rod (9), a supporting piece (4), a stator fixing device (6) and a driving device for driving the connecting rod (9) to move left and right, wherein wheels (5) are arranged under the bottom rack (1), the stator fixing device (6), the supporting piece (4) and the guide device (2) are arranged on the bottom rack (1), the stator fixing device (6) and the guide device (2) are positioned at the left side and the right side of the supporting piece (4) respectively, the connecting rod (9) is horizontally arranged on the guide device (2), the left end of the connecting rod (9) is provided with a grabbing hook (8), and the right end of the connecting rod (9) is connected with the driving device. After the device is applied, not only can the stator winding in a stator core be extracted, but also the whole extracting process is simple and easy to operate, so that the working efficiency can be improved, and the device can also be operated by a person with little strength.

Description

technical field [0001] The invention relates to a device for taking out a motor stator winding, which belongs to the technical field of motors. Background technique [0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque and serve as a power source for electrical appliances or various machines. , where the stator is composed of a stator core and a stator winding embedded in the stator core; during use, when the stator winding fails, in order to ensure that the motor can be used normally, it is generally necessary to replace the entire stator or replace the original stator winding A method of removing and reinstalling the stator windings. However, the cost of replacing the entire stator is too high, so it is preferable to take out the original stator winding and then reinstall the stator winding. [0003] At presen...
