[0001] The utility model relates to the technical field of motors, and specifically relates to an electric machine. Background Art

[0002] An electric machine refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. As a power source for electrical appliances or various machines, its main function is to convert electrical energy into mechanical energy.

[0003] Currently, existing electric machines generally include an upper end cover and a lower end cover. An upper flange is provided on the upper end cover, and a lower flange is provided on the lower end cover. A plurality of through holes are opened on both the upper flange and the lower flange. When assembling the electric machine, the upper flange and the lower flange can be fitted together so that the through holes are aligned, and then rivets are passed through for fixation. However, due to the large number of through holes and small hole diameters, it is extremely difficult to align them. Even if they are aligned, they are prone to deviation. Once the through holes are not completely aligned and the rivets are forcibly passed through and tightened, it is easy to cause damage to the through holes and make the rivet installation unstable, resulting in detachment, so that the connection between the upper end cover and the lower end cover is not firm enough, affecting the structural stability of the electric machine. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an electric machine to solve the above problems, which can keep the first through hole and the second through hole aligned and communicated before the rivet passes through, with firm connection and high structural stability.

[0005] The utility model realizes the above purpose through the following technical solutions. An electric machine includes an upper end cover and a lower end cover. A first flange is provided on the upper end cover, and a second flange is provided on the lower end cover. A plurality of first through holes are opened on the first flange, and a plurality of second through holes for communicating with the first through holes are opened on the second flange. A plurality of positioning members are provided on the first flange. The positioning members are detachably installed on the first through holes. The positioning members include insertion sleeves for passing through the second through holes, and a plurality of limiting claws for abutting against the lower surface of the second flange are provided at the bottom of the insertion sleeves.

[0006] As a further setting of the utility model, the limiting claws include a connecting section fixedly connected to the bottom of the insertion sleeve. The cross-section of the connecting section is arc-shaped. One end of the connecting section away from the insertion sleeve is connected with an abutting section, and an elastic recoil space is formed between the abutting section and the insertion sleeve.

[0007] As a further setting of the utility model, a plurality of teeth are provided at one end of the abutting section away from the connecting section.

[0008] As a further setting of the utility model, an elastic washer is bonded to the lower surface of the second flange, and the elastic washer is made of rubber material.

[0009] As a further arrangement of the present utility model, mounting sleeves are provided on the upper surface of the first flange corresponding to the positions of the first through holes, and one end of the insertion sleeve is fixed inside the mounting sleeve through a detachable structure.

[0010] As a further arrangement of the present utility model, the detachable structure includes a clamping block provided on the side wall of the insertion sleeve, a clamping groove is vertically opened inside the mounting sleeve, an annular groove communicating with the clamping groove is circumferentially opened inside the mounting sleeve, and the clamping block is used to be sequentially clamped into the clamping groove and the annular groove.

[0011] As a further arrangement of the present utility model, the limiting claws are arranged in a circumferential array with the central axis of the insertion sleeve as the center.

[0012] As a further arrangement of the present utility model, both the connecting section and the abutting section are made of ABS plastic.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] When assembling the motor of the present utility model, the positioning member can be first installed on the first through hole, and then the first flange and the second flange are fitted together, then the insertion sleeve will penetrate through the second through hole accordingly, thereby driving the limiting claws to penetrate through the second through hole and abut against the lower surface of the second flange.

Then, through the limitation of the insertion sleeve, the first through hole and the second through hole can be aligned and communicated with each other to achieve pre-positioning. Then, the rivet can be directly penetrated through the first through hole and the second through hole for fixation, and the operation is convenient. Since the first through hole and the second through hole are kept aligned and communicated before the rivet passes through, it is convenient for the insertion of the rivet, and the installation is relatively precise, and the installation stability is high, ensuring the connection firmness between the upper end cover and the lower end cover, thereby making the motor have better structural stability.

Detailed implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 As shown, a motor includes an upper end cover 1 and a lower end cover 2. A first flange 3 is provided on the upper end cover 1, and a second flange 4 is provided on the lower end cover 2. A plurality of first perforations 5 are formed in the first flange 3, and a plurality of second perforations 6 for communicating with the first perforations 5 are formed in the second flange 4. A plurality of positioning members are provided on the first flange 3, and the positioning members are detachably installed in the first perforations 5. The positioning members include an insertion sleeve 7 for passing through the second perforations 6, and a plurality of limiting claws 8 for abutting against the lower surface of the second flange 4 are provided at the bottom of the insertion sleeve 7. When assembling the motor, the positioning members can be first installed in the first perforations 5, and then the first flange 3 and the second flange 4 are fitted together. Then the insertion sleeve 7 will pass through the second perforations 6 accordingly, driving the limiting claws 8 to pass through the second perforations 6 and abut against the lower surface of the second flange 4. Through the limitation of the limiting claws 8, the pre-connection between the first flange 3 and the second flange 4 can be realized, and the state of the insertion sleeve 7 inserted into the second perforations 6 can be maintained. Through the limitation of the insertion sleeve 7, the first perforations 5 and the second perforations 6 can be aligned and communicated with each other to achieve pre-positioning. Then the rivets can be directly passed through the first perforations 5 and the second perforations 6 for fixation, which is convenient for operation. Since the first perforations 5 and the second perforations 6 are kept aligned and communicated before the rivets pass through, it is convenient for the insertion of the rivets, and the installation is relatively accurate, with high installation stability, ensuring the connection firmness between the upper end cover 1 and the lower end cover 2, so that the motor has better structural stability. The limiting claws 8 are arranged in a circumferential array centered on the central axis of the insertion sleeve 7, thus ensuring the connection firmness between the upper end cover 1 and the lower end cover 2.

[0022] Please refer to Figures 2-4As shown in the figure, the limit claw 8 includes a connecting section 9 fixedly connected to the bottom of the socket 7, and the cross-section of the connecting section 9 is arc-shaped. At one end of the connecting section 9 away from the socket 7, there is a contact section 10 connected, and an elastic return space is formed between the contact section 10 and the socket 7. When the first flange 3 and the second flange 4 are fitted together, the limit claw 8 will first be inserted into the second through hole 6. During this process, the contact section 10 will first be caught in the second through hole 6. Due to the extrusion of the inner wall of the second through hole 6, it will deflect into the elastic return space, facilitating the continuous insertion of the limit claw 8. When the limit claw 8 slides to a position below the second flange 4, since it gets rid of the extrusion of the inner wall of the second through hole 6, the contact section 10 can automatically extend and return to its original shape, thus resisting the lower surface of the second flange 4 to achieve limitation. The limitation firmness is relatively good, the operation is relatively convenient. Both the connecting section 9 and the contact section 10 are made of ABS plastic, with high strength and toughness, and having a certain elasticity, and can deform when stressed. At one end of the contact section 10 away from the connecting section 9, there are several teeth 11 provided. When the contact section 10 abuts against the lower surface of the second flange 4, due to the existence of the teeth 11, the contact end has a relatively high friction coefficient and is not easy to slip, thus ensuring the firmness of the limitation. And an elastic washer 12 is adhesively bonded to the lower surface of the second flange 4. The elastic washer 12 is made of rubber material. When the limit claw 8 slides to a position below the second flange 4, the contact section 10 can abut against the elastic washer 12. The elastic washer 12 will deform when stressed, thus firmly attaching the contact section 10, and further improving the firmness of the limitation.

[0023] Please refer to Figures 2-4As shown in the figure, mounting sleeves 13 are provided on the upper surface of the first flange 3 corresponding to the positions of the first through holes 5, and one end of the insertion sleeve 7 is fixed inside the mounting sleeve 13 through a detachable structure. When it is necessary to disassemble the upper end cover 1 and the lower end cover 2, the rivets can be removed first, and then the insertion sleeve 7 can be removed from the inside of the mounting sleeve 13, so that the positioning member can be removed and the locking can be released, so that the upper end cover 1 and the lower end cover 2 can be separated. The operation is relatively convenient and simple. Among them, the detachable structure includes a clamping block 14 provided on the side wall of the insertion sleeve 7. A clamping groove 15 is vertically opened inside the mounting sleeve 13, and an annular groove 16 communicating with the clamping groove 15 is circumferentially opened inside the mounting sleeve 13. The clamping block 14 is used to be sequentially clamped into the clamping groove 15 and the annular groove 16. When it is necessary to install the positioning member, one end of the insertion sleeve 7 can be inserted into the inner wall of the mounting sleeve 13, so that the clamping block 14 is clamped into the clamping groove 15 and slides to the connection between the clamping groove 15 and the annular groove 16. Then, the insertion sleeve 7 is rotated so that the clamping block 14 is clamped into the annular groove 16. Then, through the limitation of the annular groove 16 on the clamping block 14, the connection between the insertion sleeve 7 and the mounting sleeve 13 can be realized, so as to realize the firm installation of the positioning member on the first through hole 5. When it is necessary to disassemble the positioning member, only the insertion sleeve 7 needs to be rotated, so as to drive the clamping block 14 to slide from the annular groove 16 into the clamping groove 15, and then it can be removed through the clamping groove 15, so as to release the connection and facilitate the removal of the positioning member.
