[0034] As described in the background, the iron core rotor is one of the key components of the motor. The iron core rotor includes an iron core body, a rotating shaft and a winding, wherein the rotating shaft is coaxially connected with the iron core body by inserting the shaft hole on the iron core body; at least one slot is provided on the outer circumferential surface of the iron core body, and the winding is arranged in the slot and wound on the iron core body; the winding has a lead portion, and the lead portion is located at one side of the iron core body in the axial direction and is arranged along the circumferential direction of the rotating shaft. In the related art, in order to reduce the production cost, the iron core body and the rotating shaft are generally reused by removing the winding. In the existing operation process, the operator usually holds a cutter to cut the lead portion of the winding, so as to achieve the purpose of cutting off the winding. However, this operation method has certain risks, because it completely relies on manual operation, it is easy to cause improper control of the cutting depth, thereby causing the cutter to cut the rotating shaft.

[0035] Reference Figures 1 to 6 In order to solve the above problems, according to one aspect of the application, the embodiment of the application provides a cutting device for cutting the lead portion 1631 of the iron core rotor 1600, the iron core rotor 1600 including an iron core body 1610, a rotating shaft 1620 and a winding 1630, the rotating shaft 1620 being coaxially connected with the iron core body 1610; the winding 1630 being arranged on the iron core body 1610 and having a lead portion 1631; the lead portion 1631 being located at one side of the iron core body 1610 in a first direction and being arranged along the circumferential direction of the rotating shaft 1620, the first direction being parallel to the axial direction of the iron core rotor 1600.

[0036] The cutting device comprises a bearing seat 100, a cutting piece 200, a mounting piece 300, and a first limiting piece 400, wherein the bearing seat 100 is used for bearing the iron core rotor 1600; the cutting piece 200 can move close to or away from the bearing seat 100 along a second direction, is used for cutting the lead part 1631, and has an included angle greater than 0° and less than 180° with the first direction; the cutting piece 200 is arranged on the mounting piece 300; and the first limiting piece 400 is arranged on the mounting piece 300 and is used for limiting the cutting piece 200 from continuously moving after the cutting piece 200 moves a preset distance towards the bearing seat 100.

[0037] In the embodiment of the present application, the rotating shaft 1620 is coaxially connected with the iron core body 1610 by being inserted into the shaft hole of the iron core body 1610; the outer circumferential surface of the iron core body 1610 is provided with a plurality of grooves 1611, the plurality of grooves 1611 are arranged at intervals along the circumferential direction of the iron core body 1610, the winding 1630 is arranged in the groove 1611 and wound on the iron core body 1610.

[0038] The cutting piece 200 comprises a cutting abrasive disc 210 and a motor 220, the axial direction of the cutting abrasive disc 210 is parallel to the first direction, and the output shaft of the motor 220 is drivingly connected with the cutting abrasive disc 210 to drive the cutting abrasive disc 210 to rotate. The mounting piece 300 is a mounting rack, the cutting piece 200 is mounted on the mounting piece 300 and can slide on the mounting piece 300 along the second direction; the included angle between the second direction and the first direction is 90° and is parallel to the direction of gravity; in other embodiments, the included angle between the second direction and the first direction can also be other degrees. The first limiting piece 400 is used for limiting the cutting piece 200 from continuously moving after the cutting piece 200 moves a preset distance downwards, the preset distance is a movement distance that can make the cutting piece 200 cut off the lead part 1631, and is determined according to actual needs and is not limited here.

[0039] The first limiting piece 400 can be a limiting block fixedly installed on the upper surface of the mounting piece 300, in this case, part of the structure of the cutting piece 200 is located above the upper surface of the mounting piece 300 and is blocked by the first limiting piece 400 from continuously moving downwards by contacting the surface of the first limiting piece 400 away from the mounting piece 300; the first limiting piece 400 can also be a limiting block fixedly installed below the lower surface of the mounting piece 300, in this case, part of the structure of the cutting piece 200 is located below the lower surface of the mounting piece 300 and is blocked by the first limiting piece 400 from continuously moving downwards by contacting the surface of the first limiting piece 400 close to the mounting piece 300.

[0040] In one aspect, the first limiting member 400 can accurately limit the maximum movement distance of the cutting member 200, thereby effectively controlling the cutting depth of the cutting member 200, avoiding damage to the rotating shaft 1620 of the iron core rotor 1600 due to excessive cutting of the cutting member 200, and thereby reducing the risk of inaccurate control of the cutting depth due to manual operation. On the other hand, the carrier seat 100 provides a stable carrier platform for the iron core rotor 1600, avoiding shaking and other problems caused by manual holding, and creating favorable conditions for subsequent accurate cutting. In another aspect, the cutting member 200 cuts the lead portion 1631 by moving towards the carrier seat 100 in the second direction. This cutting action using mechanical movement is more stable and controllable than manual operation, further reducing the risk of scratching the rotating shaft 1620 when cutting the lead portion 1631 of the winding 1630.

[0041] Referring to Figure 1 and Figure 2 In one embodiment, the cutting device further comprises an operating handle 500, which is connected with the cutting member 200 and can drive the cutting member 200 to move on the mounting member 300 in the second direction. The operating handle 500 improves the convenience of cutting operation.

[0042] Referring to Figure 1 and Figure 2 In one embodiment, the first limiting member 400 comprises a limiting body 410 and a limiting cap 420, the limiting body 410 is arranged on the mounting member 300, and the limiting cap 420 is arranged on the side of the limiting body 410 away from the mounting member 300. The cutting member 200 has a limiting portion 230, and the limiting portion 230 is provided with a first limiting through hole, the limiting body 410 is arranged in the first limiting through hole, and the hole wall of the first limiting through hole is used to limit the passing of the limiting cap 420.

[0043] In this embodiment, the limiting cap 420 is coaxially arranged with the limiting body 410, and the diameter of the limiting cap 420 is greater than the diameter of the limiting body 410. The limiting portion 230 is a limiting plate and is located above the upper surface of the mounting member 300, the diameter of the first limiting through hole is greater than the diameter of the limiting body 410 and less than the diameter of the limiting cap 420. In addition, in order to enhance the limiting effect, the number of first limiting members 400 is multiple, and the multiple first limiting members 400 are arranged at intervals. The number of first limiting through holes is the same as the number of first limiting members 400, and the multiple first limiting members 400 are arranged one-to-one corresponding to the multiple first limiting through holes.

[0044] On the one hand, when the cutting member 200 moves towards the bearing seat 100 and cuts, the limiting body 410 slides in the first limiting through hole; when the cutting member 200 moves a preset distance, the limiting cap 420 is blocked by the hole wall of the first limiting through hole, thereby blocking the cutting member 200 from continuing to move towards the bearing seat 100; this limiting measure not only accurately controls the cutting depth of the cutting member 200, effectively avoids damaging the rotating shaft 1620 due to cutting too deep, but also avoids the cutting depth from being out of control due to accidental external force or other factors, effectively improving the safety and reliability of the cutting operation. On the other hand, since the limiting part 230 and the first limiting member 400 are relatively independent components, if the cutting depth of the cutting member 200 needs to be adjusted, different sizes of limiting bodies 410 or limiting caps 420 can be replaced to achieve the adjustment, thereby making the cutting device better adapt to different cutting needs.

[0045] With reference to Figure 1 and Figure 2 In an embodiment, the mounting member 300 is provided with a mounting hole, the limiting body 410 is inserted into the mounting hole, and the limiting body 410 is threadedly connected with the hole wall of the mounting hole.

[0046] In the embodiment, the mounting hole is a threaded hole, and the limiting body 410 is a threaded rod. On the one hand, the position of the limiting body 410 in the mounting hole is changed by rotating the limiting body 410, thereby indirectly controlling the limiting position of the cutting member 200, and accurately controlling the cutting depth of the cutting member 200. On the other hand, the above structure design not only facilitates the installation and disassembly and maintenance of the limiting body 410, but also improves the stability of the limiting body 410 installed on the mounting member 300.

[0047] With reference to Figures 1 to 10 In an embodiment, the bearing seat 100 is provided with a second limiting member 600, the second limiting member 600 is provided with a second limiting through hole 610 through which the lead portion 1631 passes in the first direction; the hole wall of the second limiting through hole 610 is used to block the iron core body 1610 from being inserted into the second limiting through hole 610 in the first direction.

[0048] In the embodiment, the second limiting member 600 is a limiting plate, the bearing seat 100 is provided with a first mounting groove on the surface close to the cutting member 200, and the second limiting member 600 is fixedly installed on the bearing seat 100 by being inserted into the first mounting groove; in other embodiments, the second limiting member 600 can also be fixedly installed on the bearing seat 100 by welding, clamping or gluing. The second limiting through hole 610 is arranged in the first direction, part of the structure of the lead portion 1631 will pass out of the second limiting through hole 610, and the hole diameter of the second limiting through hole 610 is greater than the maximum diameter of the lead portion 1631 and less than the maximum diameter of the iron core body 1610.

[0049] In the present application, when the cutting device performs the cutting operation, the iron core rotor 1600 is driven to move along the first direction towards the second limiting piece 600; in this process, the lead portion 1631 will pass through the second limiting through hole 610, and at the same time, due to the hole wall of the second limiting through hole 610 will block the iron core body 1610 from being inserted into the second limiting through hole 610 along the first direction, so that the iron core body 1610 will finally contact the surface of the second limiting piece 600. Then drive the cutting piece 200 to move towards the bearing seat 100, and cut the lead portion 1631 to complete the cutting operation.

[0050] The second limiting through hole 610 not only can limit the iron core body 1610, prevent the iron core body 1610 from unnecessary movement during the cutting operation, and ensure that the position of the iron core body 1610 remains stable, providing a stable operation basis for the subsequent precise cutting of the lead portion 1631. At the same time, it can accurately position the lead portion 1631, so that the lead portion 1631 can be in the correct position before cutting, facilitating the subsequent precise cutting of the cutting piece 200.

[0051] Referring to Figure 4 and Figures 6 to 10 In one embodiment, the second limiting through hole 610 penetrates the surface of the second limiting piece 600 close to the cutting piece 200, and the length of the second limiting through hole 610 along the second direction is less than the length of the lead portion 1631 along the second direction.

[0052] In the present embodiment, the second limiting through hole 610 is a semicircular hole, which can better fit the trend of the hole wall of the second limiting through hole 610 to the lead portion 1631, thereby accurately positioning the lead portion 1631, and helping to improve the cutting precision and quality.

[0053] The above structure design can make part of the structure of the lead portion 1631 exposed to the side of the second limiting piece 600 close to the cutting piece 200, which not only makes the cutting piece 200 more easily touch the lead portion 1631 when cutting the lead portion 1631 along the second direction towards the bearing seat 100, reduces the difficulty of the cutting piece 200 contacting and starting to cut the lead portion 1631, and improves the convenience of the cutting operation. At the same time, it also enables the operator to more intuitively observe the contact between the cutting piece 200 and the lead portion 1631, which helps to improve the cutting quality and efficiency and reduce cutting errors caused by inadequate observation.

[0054] Referring to Figure 5 , Figure 7 and Figure 9In an embodiment, the bearing seat 100 is provided with a limiting strip 700, which is arranged along the first direction and used to limit the rotation of the core body 1610 by being inserted into the slot 1611 of the core body 1610.

[0055] In the embodiment, the core body 1610 has three slots 1611, which are arranged along the circumference of the core rotor 1600.

[0056] In the application, when the cutting device performs the cutting operation, first, the limiting strip 700 is inserted into any one of the plurality of slots 1611; after the cutting piece 200 completes the cutting of the lead portion 1631 close to the cutting piece 200, the core body 1610 is driven to move away from the second limiting piece 600 along the second direction; after the core body 1610 is completely separated from the limiting strip 700, the limiting strip 700 is inserted into another slot 1611 of the plurality of slots 1611, and the cutting piece 200 performs the cutting process on the lead portion 1631 close to the cutting piece 200. Repeat the above operation until the lead portion 1631 is completely cut off.

[0057] The above structure design can effectively limit the rotation of the core body 1610 on the bearing seat 100, not only providing a stable operation basis for subsequent cutting operation, ensuring the accuracy and safety of the cutting operation, but also improving the cutting efficiency.

[0058] Referring to Figure 5 , Figure 7 and Figure 9 In an embodiment, the bearing seat 100 has a bearing surface 110, and the bearing surface 110 is provided with a storage groove 111; the limiting strip 700 is arranged in the storage groove 111.

[0059] In the embodiment, the storage groove 111 is a semicircular groove, and the length of the storage groove 111 along the second direction is less than the length of the core body 1610 along the second direction.

[0060] The arranged storage groove 111 not only plays a role in limiting the shaking of the core rotor 1600, but also can weaken the influence of external factors (such as slight vibration generated during cutting) on the core rotor 1600 to a certain extent, so that the core rotor 1600 can be more stably cut, ensuring the stability of the cutting process and helping to improve the cutting quality. At the same time, it also plays a positioning role, making the position of the core rotor 1600 on the bearing seat 100 more accurate.

[0061] Referring to Figure 4 and Figures 6 to 10In an embodiment, the bearing seat 100 is provided with a positioning member 800, and the positioning member 800 and the limiting strip 700 are located on opposite sides of the second limiting member 600 in the first direction; the positioning member 800 is provided with a positioning hole 810 for the rotating shaft 1620 to pass through.

[0062] In the embodiment, the positioning member 800 is a positioning plate, the bearing seat 100 is provided with a second mounting groove on the surface close to the cutting member 200, and the positioning member 800 is fixedly installed on the bearing seat 100 in a manner of being inserted into the second mounting groove; in other embodiments, the positioning member 800 can also be fixedly installed on the bearing seat 100 in a manner of welding, clamping or gluing. The positioning hole 810 is a through hole, and the rotating shaft 1620 can pass through the positioning hole 810 and be matched with the hole wall of the positioning hole 810.

[0063] Before the lead portion 1631 is prepared to be cut, the iron core rotor 1600 is first driven to move in the first direction towards the second limiting member 600; after the iron core body 1610 contacts the surface of the second limiting member 600 away from the positioning member 800, the movement is stopped, at this time, the limiting strip 700 is inserted into the groove 1611 of the iron core body 1610, the lead portion 1631 passes through the second limiting through hole 610, and the rotating shaft 1620 passes through the positioning hole 810. Then, the cutting member 200 is driven to move towards the bearing seat 100, and the lead portion 1631 is cut to be processed.

[0064] The positioning hole 810 not only plays a role of positioning the rotating shaft 1620, but also plays a role of limiting the movement of the rotating shaft 1620 in a direction perpendicular to the first direction and the second direction, thereby improving the stability of the iron core rotor 1600 on the bearing seat 100.

[0065] Reference Figure 5 In an embodiment, the bearing seat 100 has a collection slope 120, and the collection slope 120 is located on one side of the limiting strip 700 and gradually inclines away from the limiting strip 700 from the upper end of the bearing seat 100 to the lower end of the bearing seat 100.

[0066] The above structure design can guide the cutting waste to slide down to the designated collection place along the collection slope 120 under the action of gravity for unified collection and cleaning. This collection measure not only avoids the accumulation of cutting waste, keeps the cutting operation area clean and clear, and ensures the normal operation of subsequent cutting operation; but also avoids the risk of direct contact of the operator with the cutting waste, and improves the safety of the cutting operation.

[0067] Reference Figures 4 to 10In an embodiment, the bearing seat 100 is provided with a protective baffle 900 located on the side of the second limiting piece 600 away from the positioning piece 800 in the first direction; the protective baffle 900 is provided with a third limiting through hole 910 for the iron core rotor 1600 to pass through in the first direction, and the hole wall of the third limiting through hole 910 is used to limit the movement of the iron core rotor 1600 in the second direction.

[0068] In the embodiment, the bearing seat 100 is provided with a third mounting groove on the surface close to the cutting piece 200, and the protective baffle 900 is fixedly installed on the bearing seat 100 by being inserted into the third mounting groove; in other embodiments, the protective baffle 900 can also be fixedly installed on the bearing seat 100 by welding, clamping or gluing. The third limiting through hole 910 is arranged in the first direction and is a circular hole; the diameter of the third limiting through hole 910 is greater than or equal to the maximum length of the iron core rotor 1600 in the second direction. In addition, in order to facilitate the processing of the third limiting through hole 910, the surface of the protective baffle 900 away from the cutting piece 200 is provided with a processing through hole 920 communicating with the third limiting through hole 910.

[0069] On the one hand, the protective baffle 900 cooperates with the second limiting piece 600, the limiting strip 700 and the positioning piece 800 to constrain the position of the iron core rotor 1600 from multiple dimensions, so that the placement of the iron core rotor 1600 on the bearing seat 100 becomes more stable and accurate, thereby effectively avoiding the displacement of the iron core rotor 1600 due to external force and other factors during the cutting operation, and ensuring the accuracy and quality of the cutting operation. On the other hand, the protective baffle 900 can also act as a barrier to reduce the risk of damage to other components around the iron core rotor 1600 or injury to the operator himself due to operation errors (such as accidental deviation of the cutting piece 200 from the cutting path).

[0070] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 In an embodiment, the cutting device further comprises a material cleaning piece 1000 located between the second limiting piece 600 and the positioning piece 800, for cleaning the lead part 1631 cut off.

[0071] In the embodiment, the material cleaning piece 1000 can be a brush, a scraper or a dust collector. The material cleaning piece 1000 cooperates with the collection inclined surface 120 to avoid the accumulation of the lead part 1631 on the bearing seat 100, so that the cutting operation area remains clean and clear, thereby ensuring the normal operation of the subsequent cutting operation; at the same time, it also avoids the risk of direct contact of the operator with the cutting waste, thereby improving the safety of the cutting operation.

[0072] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 In an embodiment, the cleaning piece 1000 is an air nozzle, the bearing seat 100 is provided with a mounting structure 1100, and the cleaning piece 1000 is arranged on the mounting structure 1100. The mounting structure 1100 is a transparent piece.

[0073] In the embodiment, the air nozzle is arranged towards the second limiting piece 600. The mounting structure 1100 is a transparent plate, and the mounting structure 1100 is fixedly arranged on the bearing seat 100 by means of connecting screws. In other embodiments, the mounting structure 1100 can also be fixedly arranged on the bearing seat 100 by means of welding or gluing.

[0074] The cleaning piece 1000 arranged can achieve efficient and comprehensive cleaning effect. The mounting structure 1100 arranged not only plays a role of mounting and bearing the cleaning piece 1000, but also facilitates the operator to observe the cutting condition under the premise of protecting the operator.

[0075] Referring to Figure 1 and Figure 2 In an embodiment, the cutting device further comprises an adjusting nut 1200, a mounting seat 1300 and an adjusting screw rod 1400. The bearing seat 100 is arranged on the surface of the adjusting nut 1200 close to the cutting piece 200. The adjusting nut 1200 can move on the mounting seat 1300 in the first direction. The adjusting screw rod 1400 can rotate on the mounting seat 1300 and drive the adjusting nut 1200 to move by screwing with the adjusting nut 1200.

[0076] In the embodiment, the bearing seat 100 is fixedly arranged on the surface of the adjusting nut 1200 close to the cutting piece 200 by means of connecting screws. In other embodiments, the bearing seat 100 can also be fixedly arranged on the surface of the adjusting nut 1200 close to the cutting piece 200 by means of welding or gluing. The mounting seat 1300 is fixedly arranged on the mounting piece 300. In other embodiments, the mounting seat 1300 can also be fixedly arranged on other components. The length direction of the adjusting screw rod 1400 is parallel to the first direction. The adjusting screw rod 1400 rotates on the mounting seat 1300 by screwing with the mounting seat 1300. In addition, in order to ensure that the adjusting nut 1200 does not rotate on the adjusting screw rod 1400, two guide rods 1500 are arranged on the mounting seat 1300. The length directions of the two guide rods 1500 are both parallel to the first direction, and the two guide rods 1500 are arranged on opposite sides of the adjusting screw rod 1400 respectively. The adjusting nut 1200 is arranged on the guide rods 1500 and can slide on the guide rods 1500 in the first direction.

[0077] The structure design can adjust the position of the bearing seat 100 in the first direction, so as to facilitate the cutting member 200 to accurately cut the iron core rotor 1600 with different specifications and different cutting requirements, and widen the application range of the cutting device.

[0078] In summary, the cutting device provided by the embodiment has at least the following beneficial technical effects: on the one hand, the first limiting member 400 can accurately limit the maximum movement distance of the cutting member 200, thereby effectively controlling the cutting depth of the cutting member 200, avoiding damage to the rotating shaft 1620 of the iron core rotor 1600 due to excessive cutting of the cutting member 200, and reducing the risk of inaccurate control of the cutting depth due to manual operation. On the other hand, the bearing seat 100 provides a stable bearing platform for the iron core rotor 1600, avoiding shaking and other problems caused by manual holding, and creating favorable conditions for subsequent accurate cutting. On the other hand, the cutting member 200 cuts the lead portion 1631 by moving close to the bearing seat 100 along the second direction. This cutting action achieved by mechanical movement is more stable and controllable than manual operation, further reducing the risk of scratching the rotating shaft 1620 when cutting the lead portion 1631 of the winding 1630.

[0079] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
