Description

Technical Field

[0001] The utility model relates to the technical field of motors, and particularly to a combined motor stator and rotor chip. Background Art

[0002] The brushless DC motor consists of a motor main body and a driver, and is a typical mechatronic product. Since the brushless DC motor operates in an automatic control mode, it does not require an additional starting winding on the rotor like a synchronous motor under variable frequency speed regulation during heavy-load starting, nor does it generate oscillations and loss of steps when the load changes suddenly. For the permanent magnets of small and medium-sized brushless DC motors, rare earth neodymium iron boron materials with high magnetic energy levels are now mostly used;

[0003] After searching the prior art for "a rotor for a special motor" with a publication number of "CN216564687U", this device has high strength through the quenched iron layer and cast iron layer, enabling the rotor chip to have wear-resistant and corrosion-resistant properties. However, during the overlapping process of multiple-layer rotor chips, they are prone to scattering and require personnel to cooperate in sorting, increasing the labor intensity of the staff.

[0004] Therefore, a combined motor stator and rotor chip is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the utility model is to provide a combined motor stator and rotor chip to solve the above problems, and improve the problem that during the overlapping process of multiple-layer rotor chips, they are prone to scattering and require personnel to cooperate in sorting.

[0006] The utility model realizes the above purpose through the following technical solutions. The combined motor stator and rotor chip includes: a rotor chip main body, which is installed on the motor rotating shaft; a guiding component and a plurality of aligning components. The guiding component is arranged on the end face of the rotor chip main body, and the aligning components are installed on the arc surface of the rotor chip main body. The plurality of aligning components are distributed in a ring along the arc surface of the rotor chip main body. Among them, the aligning component includes a metal winding sheet fixedly connected to the arc surface of the rotor chip main body, and an anti-detachment blocking sheet is fixedly connected to the end of the metal winding sheet away from the rotor chip main body.

[0007] Preferably, the guiding component includes a top cone ring fixedly connected to the upper end of the rotor chip main body. A shaft connecting round hole is opened at the center of the rotor chip main body, and a plurality of clamping grooves are opened at the upper end of the rotor chip main body. A bottom cone hole is opened at the lower end of the rotor chip main body. The clamping grooves can be appropriately deformed according to the positioning pins on the surface of the motor rotating shaft, and are specifically adjusted according to the actual use situation.

[0008] Preferably, a bottom cone block is fixedly connected to the lower end of the metal wound sheet, and a top cone groove is opened at the upper end of the metal wound sheet. The top cone groove penetrates into the interior of the bottom cone block. The metal wound sheet in the upper layer drives the adjacent bottom cone block into the top cone groove opened at the upper end of the metal wound sheet in the lower layer to achieve the effect of auxiliary alignment.

[0009] Preferably, the connecting shaft round hole is communicated with the clamping groove, and a plurality of the clamping grooves are annularly distributed along the inner wall of the connecting shaft round hole, and the number of the clamping grooves is three.

[0010] Preferably, the bottom cone hole is communicated with the top cone ring, and the upper end of the top cone ring is matched with the bottom cone hole. The number of the top cone rings is four, which plays a role of orientation.

[0011] Preferably, the included angle between the metal wound sheet and the anti - detachment retaining piece is an acute angle. The set included angle between the metal wound sheet and the anti - detachment retaining piece can reduce the situation that the wound metal wire comes off. And because the metal wire does not come off, it can also achieve the effect of using the wound metal wire to assist the mutual alignment of multiple layers of metal wound sheets.

[0012] Preferably, the lower end of the bottom cone block is matched with the interior of the top cone groove, which improves the mutual fitting effect of the upper and lower layer rotor chip bodies.

[0013] The beneficial effects of the present utility model are:

[0014] 1. The above - mentioned combined motor stator and rotor chip can, under the action of the guiding component and the aligning component, prevent the rotor chip body from overlapping and misaligning. The device can form the effect that the upper - layer rotor chip body fits the lower - layer rotor chip body through the guiding component. Cooperating with the aligning component, the lower - layer rotor chip body will fit upward to the upper layer, so as to form a mutually fitting and fastening effect, reducing the situation that multiple - layer rotor chip bodies are prone to overlapping and misalignment.

[0015] 2. By setting the aligning component, it can play a positioning effect on the metal wire under the action of the aligning component. And through the cooperation of the bottom cone block and the top cone groove of the device, the adjacent rotor chip bodies will be closely fitted to each other. And because the included angle between the metal wound sheet and the anti - detachment retaining piece is an acute angle, the situation of the metal wire coming off is reduced. Through the metal wire, the close - fitting effect between adjacent rotor chip bodies is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-5 shown, the combined motor stator and rotor chip includes: a rotor chip main body 1, the rotor chip main body 1 is installed on the motor rotating shaft; a guiding component 2 and a plurality of alignment components 3, the guiding component 2 is arranged on the end face of the rotor chip main body 1, the alignment components 3 are installed on the arc surface of the rotor chip main body 1, and the plurality of alignment components 3 are distributed in a ring along the arc surface of the rotor chip main body 1; wherein, the alignment component 3 includes a metal winding sheet 31 fixedly connected to the arc surface of the rotor chip main body 1, and an anti - detachment retaining piece 32 is fixedly connected to the end of the metal winding sheet 31 away from the rotor chip main body 1;

[0024] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, the alignment component 3 includes a metal winding sheet 31 fixedly connected to the arc surface of the rotor chip body 1. The end of the metal winding sheet 31 away from the rotor chip body 1 is fixedly connected with an anti - detachment retaining piece 32. The lower end of the metal winding sheet 31 is fixedly connected with a bottom cone block 34. The upper end of the metal winding sheet 31 is provided with a top cone groove 33, and the top cone groove 33 penetrates into the interior of the bottom cone block 34. The included angle between the metal winding sheet 31 and the anti - detachment retaining piece 32 is an acute angle, and the lower end of the bottom cone block 34 matches the interior of the top cone groove 33. By setting the included angle between the metal winding sheet 31 and the anti - detachment retaining piece 32, the situation of the wound metal wire coming off can be reduced. When multiple metal winding sheets 31 are stacked on top of each other, the upper metal winding sheet 31 can drive the adjacent bottom cone block 34 into the top cone groove 33 opened at the upper end of the lower - layer metal winding sheet 31 to achieve the effect of auxiliary alignment. And because the metal wire is not likely to come off, the effect of using the wound metal wire to assist the alignment of multiple metal winding sheets 31 can also be achieved;

[0025] As Figure 1 , Figure 4 and Figure 5 shown in the figure, the guiding component 2 includes a top cone ring 24 fixedly connected to the upper end of the rotor chip body 1. A connecting shaft circular hole 21 is opened at the center of the rotor chip body 1. A plurality of clamping grooves 22 are opened at the upper end of the rotor chip body 1. A bottom cone hole 23 is opened at the lower end of the rotor chip body 1. The connecting shaft circular hole 21 is communicated with the clamping grooves 22, and the plurality of clamping grooves 22 are distributed in a ring along the inner wall of the connecting shaft circular hole 21. The bottom cone hole 23 is communicated with the top cone ring 24, and the upper end of the top cone ring 24 matches the bottom cone hole 23. The provided connecting shaft circular hole 21 matches the motor rotating shaft, and the clamping grooves 22 can be matched and installed with the positioning pins on the rotating shaft. And because the top cone ring 24 cooperates with the bottom cone hole 23, the lower - layer rotor chip body 1 can be guided into the interior of the upper - layer bottom cone hole 23 under the action of the top cone ring 24, so as to play a guiding role. And because the number of clamping grooves 22 is three and the number of top cone rings 24 is four, the effect of directional alignment can be achieved.

[0026] When the utility model is in use, the acute angle between the metal winding sheet 31 and the anti-disengagement sheet 32 reduces the disengagement of the wound metal wire. When multiple layers of metal winding sheets 31 are stacked on top of each other, the upper metal winding sheet 31 drives the adjacent bottom cone block 34 into the top cone groove 33 opened at the upper end of the lower metal winding sheet 31 to form alignment. Since the metal wire is not prone to disengagement, the wound metal wire can be used to assist the alignment of multiple layers of metal winding sheets 31. The coaxial round hole 21 matches the motor rotating shaft, and the clamping groove 22 is installed in a matching manner with the positioning pin on the rotating shaft. Since the top cone ring 24 cooperates with the bottom cone hole 23, the lower rotor chip body 1 is guided into the inner part of the upper bottom cone hole 23 under the action of the top cone ring 24 to play a guiding role, and the clamping groove 22 cooperates with the top cone ring 24 to play a role in directional alignment.

[0027] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
