Description

Technical Field

[0001] The present invention specifically relates to the technical field of winding manufacturing, specifically a high-precision and stable pin insertion system for motor skeletons. Background Art

[0002] The motor skeleton is a supporting structure for the motor winding, mainly made of insulating materials such as plastics. It is usually cylindrical or frame-shaped, surrounding the motor iron core or magnetic pole. There is also a metal needle-like structure on the side of the motor skeleton, usually installed at specific positions on the motor skeleton. Its main function is to serve as an interface for electrical connection, connecting the lead-out wire of the motor winding to the external circuit; When installing the pins, a press is generally used for pressure installation. Workers need to place the motor skeleton on the workbench, and then use pressure to push the punch downward to press the pins into the side of the motor skeleton using the pressure of the punch.

[0003] However, in practice, it has been noted that when installing the pins on the motor skeleton, workers need to reach their hands under the punch to pick up and place the materials. This not only has a low production efficiency but also poses a large safety hazard. Moreover, the pins need to be placed in the designated positions on the motor skeleton in advance, and the pins are prone to tilting during processing, resulting in tilting of the pins after being stressed, affecting the use. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-precision and stable pin insertion system for motor skeletons. While clamping the metal wire by symmetrically arranged U-shaped clamping brackets and automatically feeding, it cooperates with the lifting motor skeleton bracket to achieve automatic pin insertion. When the motor skeleton bracket descends, it presses the feeding claws in each individual feeder, and through the rotation of the feeding claws, automatic feeding and discharging are realized, thereby improving the production efficiency. To solve the technical problems proposed in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A high-precision and stable pin insertion system for motor skeletons, including a frame. Above the frame, a wire roller bracket is fixedly connected. The wire roller bracket is mainly composed of a column and a mounting plate, and support shafts are fixedly connected to the mounting plate in a rectangular array. A metal wire roller is sleeved outside each of the support shafts; One end of the column away from the mounting plate is fixedly connected with a metal wire guiding frame. Below the metal wire guiding frame, there is a metal wire inserting mechanism. Below the metal wire inserting mechanism, there is a motor skeleton bracket, and the motor skeleton bracket is movably connected to the frame; On the frame, there is also fixedly connected an individual feeder located on the side of the motor skeleton bracket, and a guiding slide rail is fixedly connected to one end of the individual feeder away from the motor skeleton bracket.

[0006] As a further technical solution of the present invention, the individual feeder includes a U-shaped connecting seat. The bottom of the U-shaped connecting seat is integrally provided with bottom struts fixedly connected to the frame. A receiving groove is formed at the end of the U-shaped connecting seat, and a fixed pin shaft is fixedly connected to the inner side of the receiving groove.

[0007] As a further technical solution of the present invention, a loading claw is also placed in the receiving groove. The loading claw is movably connected to the U-shaped connecting seat through the fixed pin shaft, and one end of the loading claw extends below the motor skeleton bracket.

[0008] As a further technical solution of the present invention, the motor skeleton bracket includes a lifting cylinder fixedly connected to the frame. The end of the lifting cylinder penetrates through the frame and is fixedly connected to a T-shaped frame. The side surface of the T-shaped frame is slidably matched with the metal wire insertion mechanism, and a U-shaped loading seat is also fixedly connected above the T-shaped frame.

[0009] As a further technical solution of the present invention, the U-shaped connecting seat is located on the side of the U-shaped loading seat, and the U-shaped connecting seat and the U-shaped loading seat are interconnected. The end of the guiding slide rail is fixedly connected to one end of the U-shaped connecting seat away from the U-shaped loading seat.

[0010] As a further technical solution of the present invention, the metal wire insertion mechanism includes two symmetrically arranged U-shaped clamping frames. An installation cross plate is arranged inside the U-shaped clamping frames, and the two U-shaped clamping frames are both movably connected to the installation cross plate through pin shafts.

[0011] As a further technical solution of the present invention, sliding installation plates located on the sides of the U-shaped clamping frames are symmetrically fixedly connected to the ends of the installation cross plate. A limiting slide rod passes through each sliding installation plate, and the end of the limiting slide rod penetrates through the T-shaped frame and is fixedly connected to the frame.

[0012] As a further technical solution of the present invention, triangular push blocks are arranged at the ends of the two U-shaped clamping frames away from the U-shaped loading seat, and a driving cylinder is fixedly connected above each triangular push block. The driving cylinder is fixedly connected to the wire reel bracket through a cylinder bracket arranged at the bottom.

[0013] As a further technical solution of the present invention, the driving cylinders are respectively located on both sides of the metal wire guiding frame, and a guiding roller is movably connected in the metal wire guiding frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, when the motor skeleton bracket moves downward, the side surface of the motor skeleton bracket presses the loading claw downward. Through the fixed pin shaft, the other end of the loading claw rotates upward, so that the loading claw pushes the motor skeleton above to move to the left, making it move into the motor skeleton bracket. At the same time, the processed motor skeleton in the motor skeleton bracket is ejected, realizing automatic loading and unloading. While improving the efficiency, it does not require workers to put their hands deep into the pin insertion part, thereby improving the safety during use; In the present invention, the driving cylinder pushes the triangular push block downward. Through the cooperation of the inclined surface of the triangular push block, the ends of the symmetrically arranged U-shaped clamping brackets move to both sides. Since the U-shaped clamping brackets are rotatably connected to the mounting cross plate through pin shafts, the bottoms of the U-shaped clamping brackets will approach each other to clamp the metal wire. After being clamped, the U-shaped clamping brackets cannot rotate anymore. Therefore, the U-shaped clamping brackets can only move downward following the triangular push block, thereby inserting the metal wire into the designated position of the motor skeleton. The clamping and feeding are all automatically completed, improving the automation degree and further enhancing the processing efficiency; In the present invention, the lifting cylinder pushes the T-shaped frame upward. Through the sliding cooperation between the T-shaped frame and the limiting slide rod, the U-shaped loading seat moves more smoothly when moving up and down. The U-shaped loading seat is used to lift the motor skeleton, and together with the downward moving U-shaped clamping bracket, the pin insertion action is completed. And when the T-shaped frame moves downward, it will trigger the individual feeder one by one to complete automatic loading and unloading. Description of the Drawings

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-9 , the embodiment of the present invention provides a high-precision and stable pin inserting system for a motor skeleton, including a frame 9. A wire roller support 1 is fixedly connected above the frame 9. The wire roller support 1 is mainly composed of a column and a mounting plate, and support shafts are fixedly connected in a rectangular array on the mounting plate. A metal wire roller 2 is sleeved outside each of the support shafts; One end of the column away from the mounting plate is fixedly connected with a metal wire guiding frame 4. A metal wire plugging mechanism 3 is arranged below the metal wire guiding frame 4. A motor skeleton bracket 5 is arranged below the metal wire plugging mechanism 3, and the motor skeleton bracket 5 is movably connected with the frame 9; A one-by-one feeder 6 is also fixedly connected to the frame 9 on the side of the motor skeleton bracket 5, and a guiding slide rail 7 is fixedly connected to one end of the one-by-one feeder 6 away from the motor skeleton bracket 5.

[0027] In this embodiment, the one-by-one feeder 6 includes a U-shaped connecting seat 61. A bottom support 62 fixedly connected to the frame 9 is integrally provided at the bottom of the U-shaped connecting seat 61. A storage groove 63 is opened at the end of the U-shaped connecting seat 61, and a fixed pin shaft 65 is fixedly connected to the inside of the storage groove 63.

[0028] ​Further, a loading claw 64 is also placed in the storage groove 63. The loading claw 64 is movably connected to the U-shaped connecting seat 61 through a fixing pin shaft 65, and one end of the loading claw 64 extends below the motor skeleton bracket 5.

[0029] By adopting the above technical solution, when the motor skeleton bracket 5 moves downward, the side surface of the motor skeleton bracket 5 will press down the loading claw 64. Through the fixing pin shaft 65, the other end of the loading claw 64 rotates upward, so that the loading claw 64 pushes the motor skeleton above to move to the left, making it move into the motor skeleton bracket 5. At the same time, the processed motor skeleton in the motor skeleton bracket 5 is ejected, realizing automatic loading and unloading. While improving the efficiency, it does not require workers to put their hands deep into the pin insertion part, thus improving the safety during use.

[0030] Further, the motor skeleton bracket 5 includes a jacking cylinder 53 fixedly connected to the frame 9. The end of the jacking cylinder 53 penetrates through the frame 9 and is fixedly connected with a T-shaped frame 51. The side surface of the T-shaped frame 51 is slidably matched with the metal wire insertion mechanism 3, and a U-shaped loading seat 52 is also fixedly connected above the T-shaped frame 51.

[0031] Specifically, the U-shaped connecting seat 61 is located on the side surface of the U-shaped loading seat 52, and the U-shaped connecting seat 61 and the U-shaped loading seat 52 are interconnected. The end of the guiding slide rail 7 is fixedly connected to the end of the U-shaped connecting seat 61 far away from the U-shaped loading seat 52.

[0032] By adopting the above technical solution, the jacking cylinder 53 pushes the T-shaped frame 51 to move upward. Through the sliding fit between the T-shaped frame 51 and the limiting slide rod 37, the U-shaped loading seat 52 moves more smoothly when moving up and down. The U-shaped loading seat 52 is used to jack up the motor skeleton, and cooperates with the downward moving U-shaped clamping frame 33 to complete the pin insertion action together. And when the T-shaped frame 51 moves downward, it will trigger the individual feeder 6 one by one to complete automatic loading and unloading.

[0033] Further, the metal wire insertion mechanism 3 includes two symmetrically arranged U-shaped clamping frames 33. An installation cross plate 32 is arranged inside the U-shaped clamping frames 33, and the two U-shaped clamping frames 33 are both movably connected to the installation cross plate 32 through pin shafts.

[0034] Further, the ends of the installation cross plate 32 are symmetrically fixedly connected with sliding installation plates 31 located on the side surfaces of the U-shaped clamping frames 33. A limiting slide rod 37 penetrates through each sliding installation plate 31, and the end of the limiting slide rod 37 penetrates through the T-shaped frame 51 and is fixedly connected with the frame 9.

[0035] Specifically, at one end of the two U-shaped clamping brackets 33 away from the U-shaped loading seat 52, there are triangular push blocks 34 provided, and a driving cylinder 35 is fixedly connected above each of the triangular push blocks 34. The driving cylinder 35 is fixedly connected to the wire roller bracket 1 through a cylinder bracket 36 provided at the bottom.

[0036] Furthermore, the driving cylinders 35 are respectively located on both sides of the metal wire guiding frame 4, and a guiding roller is movably connected in the metal wire guiding frame 4.

[0037] By adopting the above technical solution, the driving cylinder 35 pushes the triangular push block 34 to move downward. Through the cooperation of the inclined surface of the triangular push block 34, the ends of the symmetrically arranged U-shaped clamping brackets 33 move toward both sides. Since the U-shaped clamping brackets 33 and the mounting cross plate 32 are rotationally connected through a pin shaft, the bottoms of the U-shaped clamping brackets 33 will move closer to each other to clamp the metal wire. After clamping, the U-shaped clamping brackets 33 cannot rotate anymore. Therefore, the U-shaped clamping brackets 33 can only move downward following the triangular push block 34, thereby inserting the metal wire into the designated position of the motor skeleton. The clamping and feeding are all automatically completed, improving the degree of automation and further enhancing the processing efficiency.

[0038] Furthermore, a through hole for guiding the metal wire is also formed in the mounting cross plate 32, and the through hole is located between the two U-shaped clamping brackets 33. After the metal wire passes through the through hole, it is just located between the two U-shaped clamping brackets 33. The ends of the two U-shaped clamping brackets 33 move closer to each other to clamp the passing metal wire.

[0039] Furthermore, a cutting mechanism (not shown in the figure) fixedly connected to the wire roller bracket 1 is also provided between the U-shaped clamping bracket 33 and the U-shaped loading seat 52. The cutting mechanism mainly consists of an electric push rod and two shear blades arranged in an interlaced manner. The metal wire passes through between the two interlaced shear blades, and the electric push rod drives the shear blades to move closer to each other to cut the wire.

[0040] Furthermore, a vibrating feeder 8 is also installed at the end of the frame 9, and one end of the guiding slide rail 7 away from the U-shaped connecting seat 61 is fixedly connected to the vibrating feeder 8. A spiral track is arranged inside the vibrating feeder 8 to send the motor skeleton into the guiding slide rail 7 through the spiral track, and the motor skeleton slides into the U-shaped connecting seat 61 through the inclined guiding slide rail 7.

[0041] Furthermore, a baffle is also fixedly connected in the receiving groove 63, and the baffle is located below the end of the loading claw 64 to prevent the end of the loading claw 64 from being too heavy and causing the loading claw 64 to rotate to below the receiving groove 63, playing a role of limiting.

[0042] The working principle of the present invention is as follows: When in use, first, the metal wire on the metal wire roller 2 passes through the metal wire guiding frame 4 and is guided into the hole in the mounting cross plate 32. After passing through the hole, the metal wire is located between two symmetrically arranged U-shaped clamping frames 33. The driving cylinder 35 pushes the triangular push block 34 downward. Through the cooperation of the inclined surface of the triangular push block 34, the ends of the symmetrically arranged U-shaped clamping frames 33 move to both sides. Since the U-shaped clamping frames 33 are rotatably connected to the mounting cross plate 32 through pin shafts, the bottoms of the U-shaped clamping frames 33 will approach each other to clamp the metal wire. After being clamped, the U-shaped clamping frames 33 cannot rotate anymore, so the U-shaped clamping frames 33 can only move downward following the triangular push block 34. At the same time, the lifting cylinder 53 pushes the U-shaped feeding seat 52 upward through the T-shaped frame 51, thereby inserting the metal wire into the designated position of the motor skeleton. Then, the shearing mechanism shears the metal wire. The motor skeleton enters the U-shaped connecting seat 61 through the vibrating feeding tray 8 and the guiding slide rail 7. Since the end of the U-shaped connecting seat 61 is blocked by the T-shaped frame 51, the motor skeleton can only stay above the feeding claw 64 in the U-shaped connecting seat 61. When the T-shaped frame 51 moves downward, the side of the T-shaped frame 51 will press the feeding claw 64 downward. Through the fixed pin shaft 65, the other end of the feeding claw 64 rotates upward, so that the feeding claw 64 pushes the motor skeleton above it to move to the left until the motor skeleton moves into the motor skeleton bracket 5, and at the same time, the processed motor skeleton in the motor skeleton bracket 5 is ejected. Then, the T-shaped frame 51 moves upward again. Since the fixed pin shaft 65 is not located at the center of the feeding claw 64 but is biased towards the side close to the T-shaped frame 51, one end of the feeding claw 64 is heavier. Finally, the feeding claw 64 automatically resets by its own weight, realizing automatic feeding and discharging; the structure is simple, the operation is very convenient, and the manual labor intensity is effectively reduced.
