Description

Technical Field

[0001] This application relates to the field of motor processing technology, specifically a multi-slot cutting device for motors. Background Technology

[0002] As one of the core components of a motor, the stator is widely used in various electric drive devices. The stator typically consists of an iron core and windings. The iron core comprises multiple slots to house the winding coils. With the development of motor technology, the demands for motor power and efficiency have gradually increased, prompting continuous advancements in stator manufacturing technology. In stator manufacturing, the slot cutting process is particularly important, directly affecting the assembly quality of the stator windings, heat dissipation, and the motor's operating performance.

[0003] In traditional stator cutting processes, mechanical cutting is typically used, where a rotating tool cuts grooves into the stator core. However, traditional cutting processes have certain problems, especially in that some metal shavings remain on the processing table during the cutting process, requiring frequent cleaning by workers. Other metal shavings tend to remain in the cut grooves, thus affecting the processing of the stator core.

[0004] Therefore, this application provides a multi-groove cutting device for motors to solve the above problems. Utility Model Content

[0005] This application provides a multi-slot cutting device for motors, which aims to solve the problem mentioned in the background art that some metal shavings generated during the processing of motor stators remain on the processing table, requiring frequent cleaning by workers, while other metal shavings are easily left in the cutting slots, thus affecting the processing of the stator core.

[0006] To achieve the above objectives, this application provides the following technical solution: a multi-groove cutting device for motors, including a processing table and a clamping seat disposed opposite to the processing table, a material carrier for support is provided inside the processing table, a stator core is attached to the upper end of the material carrier, and a chip removal mechanism is provided inside the processing table.

[0007] The chip removal mechanism includes a sliding rail frame inside the processing table and a collection box slidably mounted on the sliding rail frame. An air guide hopper is located at the upper end of the collection box, and a support ring is fixedly installed inside the air guide hopper. A waste chip filter screen is detachably connected to the support ring. A baffle plate is installed inside the collection box, and a ventilation hole is opened on one side of the collection box. A polyester filter screen is installed at the ventilation hole. A negative pressure fan corresponding to the ventilation hole is installed inside the processing table. The collection box is slidably mounted on the upper end of the sliding rail frame. When it is necessary to periodically clean and collect the metal chips on the surface of the waste chip filter screen, the collection box can be pulled outwards. This method of collecting metal chips effectively avoids the waste chip filter screen from becoming clogged due to prolonged filtration of metal chips.

[0008] Preferably, a carbon fiber filter screen is provided on one side of the polyester filter screen and installed on the ventilation hole. A ventilation pipe is fixedly installed at the exhaust port of the negative pressure fan. The ventilation pipe is horizontally aligned with the ventilation hole. Both the polyester filter screen and the carbon fiber filter screen play a role in filtering and blocking the cutting fluid.

[0009] Preferably, the side of the recycling bin away from the polyester filter screen has a liquid guide port.

[0010] Preferably, a handle is installed at the upper end of the waste filter screen.

[0011] Preferably, a cylinder is installed on the processing table, and the telescopic end of the cylinder is detachably connected to one side of the material carrier. A partition plate is installed on the processing table.

[0012] Preferably, the front of the processing table is provided with a sealing door panel, and threaded holes are provided at the four corners of the sealing door panel.

[0013] This cutting equipment features a recycling bin in the waste recycling area of ​​the processing table. A loading platform is installed at the output end of a cylinder, providing support for the stator core before clamping. When the motor on the processing table drives the relatively distributed clamping seats to approach and clamp the stator core, the cylinder retracts the loading platform to separate it from the stator core. During processing, the waste material is no longer obstructed by the loading platform and falls towards the recycling bin. Since the metal chips generated during grooving mix with the cutting fluid, a waste chip filter can filter them. Simultaneously, the negative pressure air generated by the negative pressure fan and the air guide structure provide ventilation for the stator core being processed above, thus recovering the metal chips generated during grooving towards the recycling bin and preventing them from remaining in the grooves of the stator core due to a lack of external interference.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This embodiment provides a multi-slot cutting device for motors, such as... Figure 1-3 As shown, the cutting equipment includes a processing table 1 and a clamping seat 2 disposed opposite to the processing table 1. A material carrier 5 for support is provided inside the processing table 1. A stator core 3 is attached to the upper end of the material carrier 5. A chip removal mechanism 7 is provided inside the processing table 1.

[0021] The chip removal mechanism 7 includes a sliding rail frame 72 installed inside the processing table 1 and a recycling box 71 slidably installed on the sliding rail frame 72. An air guide hopper 73 is provided at the upper end of the recycling box 71. A support ring 75 is fixedly installed inside the air guide hopper 73. A waste chip filter screen 74 is detachably connected to the support ring 75. A baffle plate 76 is installed inside the recycling box 71. A ventilation hole is opened on one side of the recycling box 71. A polyester filter screen 77 is installed at the ventilation hole. A negative pressure fan 9 corresponding to the ventilation hole is provided inside the processing table 1.

[0022] Specifically, the recycling box 71 is slidably mounted on the upper end of the sliding rail frame 72. When it is necessary to periodically clean and recycle the metal shavings on the surface of the waste shavings filter screen 74, the recycling box 71 can be pulled out. This method of recycling metal shavings can effectively prevent the filter screen 74 from clogging due to prolonged filtration of metal shavings. The air guide hopper 73 is conical, which can effectively work with the negative pressure air generated by the negative pressure fan 9 to diffuse to the stator core 3 processing area and discharge the metal shavings from the stator core 3 during grooving into the air guide hopper 73. The polyester filter screen 77 and the carbon fiber filter screen 771 both play a role in filtering and blocking the cutting fluid, preventing the cutting fluid from entering the interior of the negative pressure fan 9 through the ventilation holes.

[0023] A carbon fiber filter 771 is installed on one side of the polyester filter 77 and mounted on the ventilation hole. A ventilation pipe 8 is fixedly installed at the exhaust port of the negative pressure fan 9 and is horizontally aligned with the ventilation hole.

[0024] More specifically, the ventilation duct 8 guides the negative pressure air generated by the negative pressure fan 9, and at the same time, it can form a closure when the recovery box 71 is moved to the designated position to prevent air leakage.

[0025] The side of the recycling bin 71 away from the polyester filter screen 77 has a liquid guide port 78.

[0026] It should be noted that the liquid guide port 78 on the recovery box 71, together with the guide plate 76, can effectively pour the cutting fluid into the liquid storage area on one side of the machining table 1 for equipment recycling.

[0027] A handle is mounted on the upper end of the waste filter screen 74.

[0028] A cylinder 6 is installed on the processing table 1. The telescopic end of the cylinder 6 is detachably connected to one side of the material carrier 5. A partition plate 4 is installed on the processing table 1. A sealing door plate 11 is provided on the front of the processing table 1. Threaded holes are provided at the four corners of the sealing door plate 11.

[0029] In use, a recycling box 71 is set up in the waste recycling area of ​​the processing table 1, and a loading platform 5 is installed at the output end of the cylinder 6. The loading platform 5 provides support for the stator core 3 before clamping. When the motor on the processing table 1 drives the relatively distributed clamping seats 2 to approach and clamp and position the stator core 3, the cylinder 6 will retract the loading platform 5 and separate it from the stator core 3. During the processing of the stator core 3, the waste is no longer blocked by the loading platform 5 and falls to the recycling box 71. Since the metal chips generated during grooving are mixed with the cutting fluid, the waste chip filter 74 can filter the metal chips. At the same time, the negative pressure air generated by the negative pressure fan 9 and the structure of the air guide hopper 73 provide ventilation for the stator core 3 being processed above, so that the metal chips generated during grooving are recycled to the recycling box 71, avoiding the metal chips remaining in the groove of the stator core 3 due to the lack of external interference.

[0030] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
