Description

Technical Field

[0001] This application relates to the field of motor housing manufacturing technology, specifically a positioning and feeding mechanism for motor housing manufacturing. Background Technology

[0002] In the field of motor manufacturing, the motor housing is an important component of the motor. The motor housing is usually produced by stamping and forming a disc blank. In order to facilitate the continuous production of motors, a feeding mechanism is set up between processes, and its position is adjusted to facilitate the processing of the next process.

[0003] However, after the motor housing is stamped, burrs often appear at its open end. These burrs not only affect the appearance quality of the motor housing, but also have an adverse effect on the subsequent motor assembly process. For example, in the process of inserting the stator into the motor housing or in the assembly process of the closing cover, the burrs may scratch the stator winding, leading to a decrease in the insulation performance of the motor, or even causing motor failure, affecting the reliability and service life of the motor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a selection and feeding mechanism for motor housing production, which has advantages such as adaptability to motor housings of different sizes and deburring during the selection process, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a selection and feeding mechanism for motor housing production, comprising a frame and a conveyor mounted on the top of the frame, wherein two blocking rings are slidably connected to the outer surface of the conveyor belt along its width direction, and a flipping component is installed in the middle of the two blocking rings; The flipping assembly includes two fixed plates, which are arranged along the height direction of the frame. The two fixed plates are fixedly connected to their corresponding blocking rings. The two fixed plates are linearly slidably connected to sliders along their height direction. The two sliders are rotatably connected to two rotating tubes along the width direction of the conveyor belt. The two rotating tubes are symmetrically arranged. The two rotating tubes are connected to the same rotating profile at their close ends. An L-shaped rod is fixedly installed in the middle of the rotating profile along the height of the frame. The bottom end of the L-shaped rod is horizontally set with the surface of the conveyor belt. A cylinder is fixedly installed coaxially at the bottom end of the L-shaped rod. An electromagnet is fixedly installed at the output end of the cylinder. The bottom end of the L-shaped rod is provided with a grinding mechanism for grinding burrs on the motor.

[0006] Furthermore, the polishing mechanism includes a polishing disc rotatably connected to the bottom end of an L-shaped rod, a polishing sponge fixedly connected to the side of the polishing disc near the cylinder, and the polishing disc and the cylinder being coaxially arranged.

[0007] With the above solution, when the grinding disc rotates, the grinding sponge can fully contact the burrs at the opening end of the motor housing, achieving uniform grinding and improving the grinding effect.

[0008] Furthermore, the grinding mechanism also includes a first motor, which is fixedly connected to the bottom end of the L-shaped rod. A gear is fixedly connected to the output end of the first motor, and an internal gear ring is fixedly installed on the side of the grinding disc away from the cylinder. The gear meshes with the internal gear ring.

[0009] Through the above scheme, the first motor drives the gear to rotate, the gear drives the internal gear ring to rotate, and then the grinding disc rotates, realizing the automated grinding of burrs on the open end of the motor housing, thereby improving production efficiency.

[0010] Furthermore, the frame is rotatably connected to a bidirectional lead screw along its width direction, and both ends of the bidirectional lead screw are threadedly connected to a power plate, with each power plate being fixedly connected to its corresponding blocking ring.

[0011] The above scheme uses an external power source to drive a bidirectional lead screw to rotate, causing the two power plates to move closer or further apart, thereby driving the two blocking rings to move synchronously, thus limiting the movement of motor housings of different widths and improving the versatility of the mechanism.

[0012] Furthermore, both of the retaining rings are made of a self-lubricating material.

[0013] The above solution, specifically using polytetrafluoroethylene, reduces the friction between the blocking ring and the conveyor belt, making the blocking ring slide more smoothly on the conveyor belt, while also reducing wear and extending the service life of the mechanism.

[0014] Furthermore, the flipping assembly also includes two electric actuators arranged along the height direction of the fixed plate, each electric actuator being fixedly connected to its corresponding fixed plate, and the output end of each electric actuator being fixedly connected to its corresponding slider.

[0015] The above solution allows for adjustment of the height and position of the L-shaped rod, enabling it to adapt to motor housings of different heights and sizes. This ensures that the L-shaped rod and electromagnet are concentrically aligned with the motor housing, guaranteeing accurate electromagnet adsorption and facilitating subsequent operations.

[0016] Furthermore, the flipping assembly also includes a second motor disposed on one side of one of the sliders, and the output end of the second motor is fixedly connected to its corresponding rotating tube.

[0017] With the above scheme, after the grinding is completed, the second motor drives the rotating tube to rotate, which in turn drives the L-shaped rod to flip, so that the motor housing becomes a vertical conveying state, which facilitates the subsequent stator insertion process and improves the continuity of the production process.

[0018] Furthermore, a photoelectric switch is installed on one side of one of the blocking rings.

[0019] With the above scheme, when the photoelectric switch detects that the motor housing has reached the working position, that is, when the electromagnet contacts the inner bottom wall of the housing, the conveyor stops running and the flipping component starts working, realizing automated control and improving production efficiency and accuracy.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects: This type of positioning and feeding mechanism for motor housing production achieves effective limiting of motor housings of different widths by setting adjustable spacing blocking rings, preventing the motor housings from rolling off the conveyor during movement, improving the adaptability of the mechanism to motor housings of different sizes, and thus enhancing the versatility and practicality of the mechanism. The set grinding mechanism realizes the automated grinding of burrs at the opening end of the motor housing. When the grinding disc rotates, the grinding sponge can fully contact and grind the burrs at the opening of the housing, avoiding the adverse effects of burrs on subsequent motor assembly processes, thereby ensuring the reliability and service life of the motor. By setting up a connection structure between the electric push rod, the slider, and the fixed plate, the height of the L-shaped rod can be flexibly adjusted, allowing it to adapt to motor housings of different heights and sizes. This ensures that the L-shaped rod and the electromagnet are concentrically positioned with the motor housing, guaranteeing accurate electromagnet adsorption of the motor housing. By setting up a second motor to drive the rotating tube, the L-shaped rod can be flipped. After grinding, the second motor drives the rotating tube to rotate, causing the L-shaped rod to flip and the motor housing to be in a vertical conveying state. This facilitates the subsequent stator insertion process, improves the continuity of the production process, and thus enhances overall production efficiency. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-5 This embodiment describes a positioning and feeding mechanism for motor housing production, comprising a frame 1 and a conveyor 2 mounted on the top of the frame 1. Two blocking rings 3 are slidably connected to the outer surface of the conveyor belt along its width direction. A flipping assembly 4 is installed in the middle of the two blocking rings 3. A bidirectional lead screw 6 is rotatably connected to the frame 1 along its width direction. Power plates 7 are threaded to both ends of the bidirectional lead screw 6, and each power plate 7 is fixedly connected to its corresponding blocking ring 3. One end of the bidirectional lead screw 6 is fixedly connected to the output end of an external power source. The external power source drives the bidirectional lead screw 6 to rotate, causing the two power plates 7 to move closer or further apart, thereby driving the two blocking rings 3 to move synchronously. This achieves the limiting of motor housings of different widths, improving the versatility of the mechanism. The two blocking rings 3 are made of self-lubricating material, specifically polytetrafluoroethylene (PTFE). This design reduces the friction between the blocking rings 3 and the conveyor belt, making the blocking rings 3 slide more smoothly on the conveyor belt, while also reducing wear and extending the service life of the mechanism.

[0025] The flipping assembly 4 includes two fixed plates 401, which are arranged along the height direction of the frame 1. The two fixed plates 401 are fixedly connected to their corresponding blocking rings 3. The two fixed plates 401 are linearly slidably connected to sliders 402 along their height direction. The two sliders 402 are rotatably connected to two rotating tubes 403 along the width direction of the conveyor belt. The two rotating tubes 403 are symmetrically arranged.

[0026] Two rotating tubes 403 are connected to the same rotating profile 404 at their close ends. The connection between the rotating profile 404 and the rotating tube 403 does not interfere with the adjustment of the spacing of the blocking ring 3. At the same time, the rotating tube 403 can drive the rotating profile 404 to rotate, which facilitates the subsequent flipping operation of the motor housing. An L-shaped rod 405 is fixedly installed in the middle of the rotating profile 404 along the height direction of the frame 1. The bottom end of the L-shaped rod 405 is set horizontally with the surface of the conveyor belt. A cylinder 406 is fixedly installed coaxially at the bottom end of the L-shaped rod 405. An electromagnet 407 is fixedly installed at the output end of the cylinder 406. The blocking ring 3 can limit the movement of the motor housing and prevent it from rolling off the conveyor 2 during movement. When the motor housing moves to the L-shaped rod 405, the bottom end of the L-shaped rod 405 is inserted into the interior of the motor housing, so that the electromagnet 407 contacts and attracts the bottom wall of the motor housing.

[0027] The bottom end of the L-shaped rod 405 is equipped with a grinding mechanism 5 for removing burrs from the motor housing. Micro motor housings are often produced by stamping disc blanks, which are prone to burrs at their open ends. The cylinder 406 pulls the motor housing towards the grinding mechanism 5, causing its open end to contact the mechanism. The grinding mechanism 5 then removes the burrs, improving the quality of the motor housing and ensuring a smoother assembly process. The grinding mechanism 5 includes a grinding disc 501 rotatably connected to the bottom end of the L-shaped rod 405. A grinding sponge 502 is fixedly connected to the side of the grinding disc 501 closest to the cylinder 406. The grinding disc 501 and the cylinder 406 are coaxially aligned. When the grinding disc 501 rotates... The polishing sponge 502 can fully contact the burrs at the opening end of the motor housing to achieve uniform polishing and improve the polishing effect. The polishing mechanism 5 also includes a first motor 503, which is fixedly connected to the bottom end of the L-shaped rod 405. A gear 504 is fixedly connected to the output end of the first motor 503. An internal gear ring 505 is fixedly installed on the side of the polishing disc 501 away from the cylinder 406. The gear 504 meshes with the internal gear ring 505. The first motor 503 drives the gear 504 to rotate, which in turn drives the internal gear ring 505 to rotate, thereby causing the polishing disc 501 to rotate, realizing automated polishing of the burrs at the opening end of the motor housing and improving production efficiency.

[0028] The flipping assembly 4 also includes two electric actuators 408 arranged along the height direction of the fixed plate 401. Each electric actuator 408 is fixedly connected to its corresponding fixed plate 401, and the output end of each electric actuator 408 is fixedly connected to its corresponding slider 402. Through the above arrangement, the height position of the L-shaped rod 405 can be adjusted, thereby allowing the L-shaped rod 405 to adapt to motor housings of different heights and sizes. This ensures that the L-shaped rod 405 and the electromagnet 407 are concentrically positioned with the motor housing, ensuring that the electromagnet 407 accurately attracts the motor housing, facilitating subsequent operations. The flipping assembly 4 also includes one slider 402 with a... The second motor 8 is fixedly connected to its corresponding rotating tube 403. After grinding, the second motor 8 drives the rotating tube 403 to rotate, which in turn drives the L-shaped rod 405 to flip, so that the motor housing becomes a vertical conveying state, which facilitates the subsequent stator insertion process and improves the continuity of the production process. A photoelectric switch 9 is installed on one side of one of the blocking rings 3. When the photoelectric switch 9 detects that the motor housing has reached the working position, that is, when the electromagnet 407 contacts the inner bottom wall of the housing, the conveyor 2 stops running and the flipping component 4 starts to work, realizing automated control and improving production efficiency and accuracy.

[0029] The working principle of the above embodiment is as follows: According to the width of the motor housing, the bidirectional lead screw 6 is driven to rotate by an external power source. The rotation of the bidirectional lead screw 6 will cause the two power plates 7 to move closer or further apart, thereby driving the two blocking rings 3 to move synchronously, so that the distance between the two blocking rings 3 is adapted to the width of the motor housing, which plays a limiting role on the motor housing and prevents it from rolling off the conveyor 2 during the movement.

[0030] Conveyor 2 moves the flat-lying motor housing. When the motor housing moves with conveyor 2 to the position of photoelectric switch 9 on one side of one of the blocking rings 3, photoelectric switch 9 detects that the motor housing has reached the working position. At this time, conveyor 2 stops running. At this time, the bottom end of L-shaped rod 405 corresponds to the inside of the motor housing. Electromagnet 407 contacts the bottom wall of the motor housing and attracts the motor housing. Cylinder 406 drives electromagnet 407 to pull the opening of the motor housing to contact the polishing sponge 502. The first motor 503 starts to work, and its output... The end drives the gear 504 to rotate. Since the gear 504 is meshed with the internal gear ring 505 on the grinding disc 501, the rotation of the gear 504 will drive the internal gear ring 505 to rotate, thereby causing the grinding disc 501 to rotate. A grinding sponge 502 is fixedly connected to the side of the grinding disc 501 near the cylinder 406. When the grinding disc 501 rotates, the grinding sponge 502 can fully contact the burrs at the opening end of the motor housing, and uniformly grind the burrs, improve the quality of the motor housing, and avoid the burrs from having an adverse effect on the subsequent motor assembly process.

[0031] If the height of the motor housing is different, the height of the L-shaped rod 405 can be adjusted by the electric push rod 408. The extension and retraction of the output end of the electric push rod 408 will drive the slider 402 to slide linearly along the height direction of the fixed plate 401, thereby adjusting the height of the L-shaped rod 405 so that the L-shaped rod 405 can adapt to motor housings of different heights. This ensures that the L-shaped rod 405 and the electromagnet 407 are concentrically set with the motor housing, ensuring that the electromagnet 407 accurately attracts the motor housing. After grinding is completed, the second motor 8 set on one side of one of the sliders 402 starts, and its output end drives the rotating tube 403 fixedly connected to it to rotate. Since the two rotating tubes 403 are connected to the same rotating profile 404 at their close ends, and the L-shaped rod 405 is fixedly installed in the middle of the rotating profile 404, the rotation of the rotating tube 403 will drive the L-shaped rod 405 to flip, so that the motor housing attracted by the electromagnet 407 becomes a vertical conveying state, which facilitates the subsequent stator insertion process.
