Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically, it demonstrates a magnet fitting folding device. Background Technology

[0002] In the production and processing of brushless motor equipment, magnets need to be installed into steel sleeves. Currently, a hand press is typically used to rivet the magnets into the steel sleeves. After riveting, to ensure the stability of the connection between the magnet and the steel sleeve, the two ends of the steel sleeve need to be folded to finish the edges and prevent the magnet from accidentally slipping out. Currently, a riveting machine is also used to flatten the sides of the steel sleeve. However, when using a riveting machine to perform vertical riveting operations on the steel sleeve, it may cause longitudinal deformation of the steel sleeve. This will affect the final product molding quality, and the edge finishing effect of riveting is inconsistent and unsightly. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic steel kit folding device that has a simple and practical structure, high consistency, and high product molding quality.

[0004] The technical solution is as follows:

[0005] A magnetic steel fitting folding device includes a worktable, on which:

[0006] Rotate the clamping assembly to clamp the magnet assembly and rotate it;

[0007] The loading and conveying unit is located directly above the rotary clamping unit and is connected to a lifting drive module to transport the magnet assembly to the rotary clamping unit.

[0008] Flip the assembly to rotate the magnet assembly 180°.

[0009] The folding pressure roller is vertically set and connected to a drive mechanism. The drive mechanism drives the folding pressure roller to move horizontally and rise vertically relative to the magnetic steel kit on the rotating clamping assembly.

[0010] Optionally, the center of the folding pressure roller and the clamping center of the rotary clamping assembly are on the same vertical plane. During operation, the lowest point of the folding pressure roller should be lower than the highest point of the magnet assembly on the rotary clamping assembly. This ensures the consistency of the folding action for each magnet assembly.

[0011] Optionally, the driving mechanism includes a side frame, a base plate, a mounting plate, a horizontal cylinder, and a vertical cylinder. The base plate is movably mounted on the side frame via a slider rail assembly, and the vertical cylinder drives the base plate to move vertically. The mounting plate is movably mounted on the base plate via a slider rail assembly, and the horizontal cylinder drives the mounting plate to move horizontally. The folding pressure roller is connected to the mounting plate. Thus, the driving mechanism drives the folding pressure roller to move horizontally and vertically relative to the magnetic steel assembly on the rotating clamping assembly, approaching the top of the magnetic steel assembly.

[0012] Optionally, the loading and conveying assembly includes a conveying cylinder, which is hollow inside, and a metal insert body is disposed in the middle of the conveying cylinder along its length. Since the magnet is magnetic, when the metal insert body inside the conveying cylinder is inserted into the interior of the magnet kit, a magnetic attraction will be formed between the two, and the magnet kit will be attracted to the conveying cylinder, thereby realizing the conveying of the magnet kit.

[0013] Optionally, the flipping assembly includes a lifting cylinder, a rotating cylinder, a gripper cylinder, and a pair of gripping arms. The lifting cylinder drives the rotating cylinder to move up and down, the rotating cylinder drives the gripper cylinder to rotate 180°, and the gripper cylinder drives the two gripping arms to close or separate. Thus, the flipping effect of the magnetic steel kit is achieved through the coordinated action of the lifting cylinder, rotating cylinder, and gripper cylinder.

[0014] The clamping arm has a clamping groove on its inner sidewall to ensure that the magnet assembly will not accidentally fall off during the clamping and flipping process.

[0015] Optionally, the rotary clamping assembly is a pneumatic chuck. It can automatically center and clamp the magnetic steel assembly, and the clamping force is stable and adjustable, resulting in high work efficiency.

[0016] Compared with existing technologies, the advantages of this invention are as follows: The magnetic steel assembly is clamped and rotated by a rotating clamping assembly, driving the folding pressure roller to move until it contacts the top edge of the magnetic steel assembly. The roller continues to move forward a short distance to force the top edge of the magnetic steel assembly to bend. During the rotation of the magnetic steel assembly, a circumferential folding action is completed on its top edge. After one end of the magnetic steel assembly is folded, the flipping assembly flips the assembly 180°, and the above actions are repeated to complete the folding of the other end. This folding device has high working efficiency and high working precision, and will not damage the steel sleeve of the magnetic steel assembly, greatly improving product manufacturing quality.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a magnetic steel kit folding device to solve the technical problems mentioned in the background art. For example... Figure 1 , Figure 2 and Figure 3 As shown, specifically, a rotary clamping assembly 2, a loading and conveying assembly 3, a flipping assembly 5, and a folding pressure roller 6 are arranged on a workbench 1. The loading and conveying assembly 3, the flipping assembly 5, and the folding pressure roller 6 are respectively distributed outside the rotary clamping assembly 2. The rotary clamping assembly 2 uses a pneumatic chuck with current technology, which can automatically center, clamp and rotate the magnetic steel kit, and the clamping force is stable and adjustable, resulting in high work efficiency. The loading and conveying assembly 3 is located directly above the rotary clamping assembly 2 and is connected to a lifting drive module 4. It is used to transport the magnetic steel kit to the rotary clamping assembly 2. The lifting drive module 4 can drive the loading and conveying assembly 3 to move up and down relative to the rotary clamping assembly 2, so that the magnetic steel kit transported on the loading and conveying assembly 3 is accurately clamped and fixed by the rotary clamping assembly 2. The flipping assembly 5 can flip the magnetic steel kit on the rotating clamping assembly 2 by 180° because the two ends of the steel sleeve on the magnetic steel kit need to be folded. After one end is folded, it needs to be flipped 180° to fold the other end. The folding pressure roller 6 is set in a vertical position and is mounted on a driving mechanism 7. The driving mechanism 7 drives the folding pressure roller 6 to move horizontally and rise and fall vertically relative to the magnetic steel kit on the rotating clamping assembly 2 so that the folding pressure roller can approach the top edge of the steel sleeve on the magnetic steel kit and apply a certain force.

[0023] The center of the folding pressure roller 6 and the clamping center of the rotary clamping assembly 2 are on the same vertical plane. During operation, the lowest point of the folding pressure roller 6 must be lower than the highest point of the steel sleeve on the magnet assembly 2. This ensures that the folding action is performed normally and that the folding action of each magnet assembly is consistent.

[0024] In this embodiment, the drive mechanism 7 includes side frames 71, a base plate 72, a mounting plate 73, a horizontal cylinder 74, and a vertical cylinder 75. Two side frames 71 arranged parallel to each other at a left-right interval are mounted on the worktable 1. The horizontally positioned base plate 72 is movably mounted on the side frames 71 via a slider rail assembly 76. The vertical cylinder 75 drives the base plate 72 to move vertically up and down. The vertical cylinder 75 is mounted on the worktable 1. The horizontally positioned mounting plate 73 is movably mounted on the top of the base plate 72 via the slider rail assembly 76. The horizontal cylinder 74 drives the mounting plate 73 to move horizontally back and forth. The horizontal cylinder 74 is mounted on the base plate 72. The folding pressure roller 6 is rotatably connected to the front end of the mounting plate 73. Thus, the drive mechanism drives the folding pressure roller to move horizontally and vertically relative to the magnet assembly on the rotating clamping assembly, so as to approach the top of the magnet assembly.

[0025] In this embodiment, the loading and conveying assembly 3 includes a conveying cylinder 31, which is hollow inside. A metal insert 32 along its length is disposed in the middle of the conveying cylinder 31. The conveying cylinder 31 is connected to the output end of the lifting drive module 4. The magnetic steel kit is composed of a steel sleeve and a cylindrical magnetic steel riveted together. The magnetic steel has a hollow area in the middle. Because the magnetic steel is magnetic, when the metal insert in the conveying cylinder is inserted into the magnetic steel kit, a magnetic attraction is formed between the two. The magnetic steel kit is attracted to the conveying cylinder, thereby realizing the conveying of the magnetic steel kit. When the magnetic steel kit is sent to the rotary clamping assembly and clamped by it, the conveying cylinder only needs to move upward to separate from the magnetic steel kit.

[0026] In this embodiment, the flipping assembly 5 includes a lifting cylinder 51, a rotating cylinder 52, a gripper cylinder 53, and a pair of gripping arms 54. The lifting cylinder 51 is mounted on the worktable 1. The lifting cylinder 51 drives the rotating cylinder 52 to move up and down, the rotating cylinder 52 drives the gripper cylinder 53 to rotate 180°, and the gripper cylinder 53 drives the two gripping arms 54 to close or separate. Thus, the flipping effect of the magnetic steel kit is achieved through the coordinated action of the lifting cylinder, the rotating cylinder, and the gripper cylinder. First, the gripper cylinder drives the two gripping arms to close together to clamp the magnetic steel kit. Then, the lifting cylinder controls it to move upward a certain distance. Next, the rotating cylinder drives the gripper cylinder to flip the magnetic steel kit 180°. Finally, the lifting cylinder controls it to move downward so that the magnetic steel kit is clamped by the rotating gripping assembly again.

[0027] The clamping arm 54 has a clamping groove 541 on its inner side wall, which can be designed in a V-shape. This groove is well-suited for cylindrical magnetic steel kits, ensuring that the magnetic steel kits will not accidentally fall off during clamping and flipping.

[0028] In this embodiment, when the folding device is in use: the loading and conveying group 3 receives a magnetic steel kit and is driven by the lifting drive module 4 to transport it to the position of the rotating clamping group 2. The magnetic steel kit is held vertically by the rotating clamping group 2, and the rotating clamping group 2 also causes the magnetic steel kit to rotate continuously at a certain speed. The driving mechanism 7 controls the folding pressure roller 6 to move towards the magnetic steel kit, and the lowest point of the folding pressure roller 6 is slightly lower than the highest point of the magnetic steel kit, until the folding pressure roller 6 begins to contact the top edge of the magnetic steel kit and continues to press forward a short distance. During the rapid rotation of the magnetic steel kit, the lower part of the folding pressure roller 6 completes the circumferential folding action on its top edge. After one end of the magnetic steel kit is folded, the flipping group 5 flips the magnetic steel kit 180°, and then repeats the above action to complete the folding of the other end of the magnetic steel kit, and the finished product is taken away. Then the above process is repeated.

[0029] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
