Description

Technical Field

[0001] This utility model belongs to the field of generator stator processing technology, and in particular relates to a generator stator insulation paper winding and reinforcement tooling. Background Technology

[0002] The generator stator is the stationary part of the motor. Its main components include the iron core, frame, and coils. The generator stator is one of the key components of the generator. For high-voltage, high-capacity synchronous motors, a rotating magnetic pole structure is used. Because the capacity and voltage of the excitation section are often much smaller than those of the armature, the armature is mounted on the stator, and the main magnetic poles are mounted on the rotor. The main function of the generator stator is to generate voltage by cutting the magnetic field generated by the rotating magnetic field in the rotor.

[0003] In the stator manufacturing process, inserting insulating paper into the slots is to effectively prevent short circuits between motor windings and between windings and the iron core. Good insulation performance can also improve motor efficiency. However, the insulating paper usually needs to protrude from both ends of the stator. In order to strengthen the circumferential support of the insulating paper, multiple turns of insulating tape need to be wrapped around the insulating paper. Existing equipment does not have the function of wrapping the insulating tape around the insulating paper. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a generator stator insulation paper winding and reinforcement tooling, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The connecting rod is located on one side of the generator stator body. A connecting sleeve is connected to the end face of the connecting rod near the generator stator body. The connecting sleeve is covered with a rubber tube. A servo motor that drives the connecting rod to rotate is located on one side of the connecting rod. A support disc is located between the servo motor and the connecting rod.

[0008] Furthermore, the base of the servo motor is fixed to the side of the support disk, and the output end of the servo motor passes through the center of the support disk and is connected to the connecting rod.

[0009] Furthermore, a support bracket is fixed to the bottom of the support disc, a support base plate is fixed to the bent part at the bottom of the support bracket, a stator support plate is fixed to the top of the support base plate, and the bottom of the generator stator body is in contact with the upper surface of the stator support plate.

[0010] Furthermore, a lead screw is installed inside the cavity of the connecting tube, and a tube moving groove is opened on the surface of the connecting tube. A limiting stop rod that moves radially along the tube moving groove is fitted on the outside of the lead screw.

[0011] Furthermore, the port of the connecting tube is provided with an external thread, and a positioning nut is screwed onto the surface of the external thread.

[0012] Furthermore, the shank end of the lead screw protrudes from the port connecting the insert.

[0013] Furthermore, the surface of the connecting rod is provided with a socket, a mounting plate is inserted into the socket, and a freely rotatable pressure rod is inserted into the surface of the mounting plate.

[0015] This utility model has the following beneficial effects:

[0016] This invention uses a stator support plate to lift and erect the generator stator body, placing it on one side of a support disc. A tape sleeve can be fitted over the connecting sleeve, with its front end touching the exposed insulating paper. A servo motor drives the connecting rod to rotate, causing the connecting sleeve to move the tape sleeve in a circular motion around the outer ring of the insulating paper. This automatically winds the tape sleeve around the outer ring of the insulating paper, improving the stator's processing efficiency. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-5 As shown, this utility model is a generator stator insulation paper winding and reinforcement tooling, including a generator stator body 1. After inserting insulation paper into the groove of the generator stator body 1, the two ends of the insulation paper are exposed from both ends of the generator stator body 1. The entire device is supported by a stator support plate 2. The stator support plate 2 has an arc-shaped plate structure and can support a specific generator stator body 1. A support base plate 3 is fixed at the bottom of the stator support plate 2. A support bracket 4 extending upward is fixed on the other side of the support base plate 3. The whole is supported by the support base plate 3. A support disc 5 is fixed at the top of the support bracket 4. A servo motor 6 is installed on one side of the support disc 5, and the base of the servo motor 6 is fixed on the surface of the support disc 5. The output end of the servo motor 6 passes through the center of the support disc 5 to the other side, and a connecting rod 7 is connected to the surface of the output end of the servo motor 6. The connecting rod 7 can rotate on the side of the support disc 5 close to the generator stator body 1 by driving the servo motor 6.

[0027] A connecting sleeve 8 is installed on one side of the top of the connecting support rod 7. The connecting sleeve 8 can rotate freely. An adhesive tape tube 9 can be installed outside the connecting sleeve 8. The inner diameter of the hole of the adhesive tape tube 9 is larger than the outer diameter of the connecting sleeve 8, so that the adhesive tape tube 9 can rotate freely. In use, the front end of the adhesive tape tube 9 is pulled out and pressed against the surface of the insulating paper. As the connecting support rod 7 rotates, the adhesive tape tube 9 moves in a circular motion, so that the insulating tape pulled out by the adhesive tape tube 9 can be wrapped around the ring-shaped insulating paper.

[0028] To improve the stability of the tape roll 9 and reduce lateral swaying, the connecting sleeve 8 is designed to be hollow, with the lead screw 12 placed inside the hollow groove of the connecting sleeve 8. A sleeve moving groove 10, communicating with the hollow groove, is also formed on the surface of the connecting sleeve 8. A limiting stop 11, which can move radially within the groove 10, is installed inside the groove. One end of the lead screw 12 is rotatably connected to the inner wall of the groove in the connecting sleeve 8, while the other end protrudes from the groove opening of the connecting sleeve 8. The protruding part is used for manual operation, and a moving sleeve engages with the lead screw 12. The bottom of the insert moving groove 10 is connected to the moving sleeve. Driven by the screw 12, the limiting stop 11 can move along the groove of the insert moving groove 10 to limit one side of the tape tube 9. The outer wall of the end of the insert 8 is also provided with an external thread 13. A positioning nut 14 can be screwed into the external thread 13 to limit the tape tube 9 on the other side. In this way, the tape tube 9 is restricted as much as possible between the positioning nut 14 and the limiting stop 11, which can reduce the left and right swing during the rotation of the tape tube 9 and improve the flatness of the insulation paper winding.

[0029] The surface of the connecting rod 7 has an insertion hole into which an assembly plate 16 is inserted. A freely rotatable pressure rod 15 is inserted into the surface of the assembly plate 16. The pressure rod 15 has an L-shaped structure, with the bent part of the pressure rod 15 extending towards one side of the insulating paper, and the end of the pressure rod 15 pressing against the adhesive tape tube 9 outside the insulating paper. The surface of the assembly plate 16 has a positioning insertion hole 17 arranged in an arc-shaped array. A positioning insertion rod 18 is inserted into the hole of the positioning insertion hole 17. The positioning insertion rod 18 can be inserted into the appropriate positioning insertion hole 17, and the bottom of the pressure rod 15 and the side of the positioning insertion rod 18 are hooked with a spring. The spring is not shown in the figure. The spring force gives the pressure rod 15 a downward rotational force, which further presses the adhesive tape tube 9 onto the insulating paper, strengthening the circumferential support of the insulating paper.

[0030] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
