Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically, it demonstrates a semi-automatic magnet assembly folding mechanism. Background Technology

[0002] During the production and processing of brushless motor equipment, magnets need to be installed into steel sleeves. Currently, a hand press is usually used to rivet the magnets into the steel sleeves. After riveting, in order to ensure the connection stability between the magnets and the steel sleeves, the two ends of the steel sleeves need to be folded to tighten the edges of the steel sleeves and prevent the magnets from accidentally slipping out of the steel sleeves.

[0003] The existing technology involves an operator using a riveting machine to press and flatten the side edge of the steel sleeve inward. However, when the operator uses the riveting machine to perform a vertical riveting action on the steel sleeve, it will generate longitudinal extrusion force on the steel sleeve, causing the steel sleeve to deform, which will affect the final product forming quality. Utility Model Content

[0004] The purpose of this invention is to provide a semi-automatic magnetic steel kit folding mechanism, which has a simple and practical structure and produces high-quality products.

[0005] The technical solution is as follows:

[0006] A semi-automatic magnetic steel kit folding mechanism includes a worktable, on which the following are provided:

[0007] Rotary clamping module for laterally clamping the magnet assembly and allowing it to rotate;

[0008] The displacement seat is located on the side of the rotary clamping module. A linear driver is provided between the displacement seat and the worktable surface so that the displacement seat can move relative to the rotary clamping module. The direction of movement of the displacement seat is parallel to the rotary clamping end face of the rotary clamping module.

[0009] A base is located in the middle of the displacement seat. The top of the base is rotatably connected to a rotating plate via a shaft. The rotating plate is driven by a drive structure to rotate around the pivot point of the base.

[0010] The working pressure roller is connected to the rotating plate via an adapter, and the working pressure roller is vertically arranged.

[0011] In addition, the above embodiments of this utility model may also have the following additional technical features:

[0012] According to one embodiment of this utility model, the driving structure includes a gear, a rack, and a cylinder. The gear is disposed inside the base and mounted on the shaft, rotating relative to the base along with the shaft. The rack movably passes through the base and meshes with the gear. The cylinder is disposed on the displacement seat, and its telescopic end is connected to the rack. The transmission of the gear and rack converts the linear motion of the cylinder into angular rotation of the rotating plate, which is more stable than directly pushing and pulling the rotating plate with the cylinder, avoiding drift in the rotation angle of the rotating plate.

[0013] The displacement seat is equipped with a blocking block, which is positioned directly opposite the end of the rack. This limits the rack's travel to protect the rack and pinion system and ensure its proper operation.

[0014] The blocking block is equipped with a threaded screw that abuts against the end of the rack. The adjusting screw allows for quick adjustment of its positioning distance relative to the rack for different kit sizes.

[0015] Based on the above technical solution, the rack is connected to the telescopic end of the cylinder via a balance block. A rotatable guide roller is located at the bottom of the balance block, and a guide slide is formed on the top surface of the displacement seat to allow the guide roller to move linearly. The cooperation between the guide roller and the guide slide ensures the straightness of the rack during movement, thereby constraining the direction of the rack's trajectory.

[0016] According to one embodiment of this utility model, a rotatable pulley is provided at the bottom end of the rotating plate, and an arc-shaped guide groove is formed on the top surface of the base. The pulley is located within the guide groove and can move along the path of the guide groove. The cooperation between the pulley and the guide groove ensures the stability of the rotation of the rotating plate.

[0017] According to one embodiment of this utility model, the middle part of the shaft is rotatably mounted in the base via a bearing component. This makes the rotation of the shaft smooth and facilitates cyclic reciprocating motion.

[0018] According to one embodiment of this utility model, a screw is provided on one side of the working pressure roller, and the screw passes through the adapter body and is fastened by a nut. This makes the working pressure roller adjustable for disassembly and assembly, facilitating replacement and use.

[0019] Compared with existing technologies, the advantages of this invention are as follows: the rotary clamping module clamps the magnetic steel kit; the displacement seat adjusts its position via a linear driver, bringing its working pressure roller approximately close to the edge of the magnetic steel kit to be folded; the rotating plate rotates via a drive structure to adjust the angle of its working pressure roller, ensuring its wheel surface contacts the edge of the magnetic steel kit to be folded and applies pressure; simultaneously, the rotary clamping module drives the magnetic steel kit to rotate. As the magnetic steel kit rotates, its edge passes under the wheel surface of the fixed-position working pressure roller, gradually completing the folding action. This folding mechanism, through a controllable movable and rotating working pressure roller, in conjunction with a rotatable rotary clamping module, achieves inward bending of the edge of the magnetic steel kit.

Detailed Implementation

[0024] 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.

[0025] This utility model provides a semi-automatic magnetic steel kit folding mechanism to solve the technical problems mentioned in the background art. For example... Figure 1 , Figure 2 and Figure 3As shown, specifically, a rotary clamping module 2 and a displacement seat 3 are arranged on a horizontal worktable 1. The displacement seat 3 is equipped with a base 5, a working pressure roller 7, and a drive structure 9. The rotary clamping module 2 is used to clamp the magnet assembly laterally and rotate it. The rotary clamping module 2 of this application adopts an existing pneumatic rotary chuck spindle assembly, which has automatic clamping and rotation functions. It clamps the lateral magnet assembly from the side and drives it to rotate. The displacement seat 3 is located to the side of the rotary clamping module 2, usually on the front side or a side that is easy to operate. A linear actuator 4, such as an existing single-axis linear slide module, is arranged between the displacement seat 3 and the worktable 1 to realize the linear movement of the displacement seat 3 relative to the worktable 1, thereby changing the relative position of the displacement seat 3 and the rotary clamping module 2. It is worth noting that the linear direction of movement of the displacement seat 3 is parallel to the rotary clamping end face of the rotary clamping module 2. That is to say, the displacement seat moves linearly along the side of the magnet assembly.

[0026] The base 5 is located in the middle of the displacement seat 3, approximately in the center, and mainly serves as a fulcrum for the subsequent installation of the rotating plate 6. A rotating plate 6 is rotatably connected to the top of the base 5 via a shaft 51. For example, the base 5 has internal installation space. The middle part of the shaft 51 is rotatably mounted inside the base 5 via a bearing 52, with its top end slightly protruding upwards for connection with the rotating plate 6. That is, the rotating plate 6 and the shaft 51 can rotate together relative to the base 5. The rotating plate 6 is driven by a drive structure 9 to rotate along the fulcrum (shaft) of its connection with the base 5.

[0027] The working pressure roller 7 is connected to the rotating plate 6 via an adapter 8. The adapter 8 is used to adjust the height of the working pressure roller 7 so that its horizontal center axis is as consistent as possible with the horizontal center axis of the magnet kit. The working pressure roller 7 is set vertically, that is, its axial direction is horizontal. This posture best meets the requirements for bending the outer edge of the magnet kit. When the pressure roller applies pressure to the magnet kit, its outer circumferential surface can roll and contact the edge of the magnet kit.

[0028] like Figure 3As shown, the drive structure 9 includes a gear 91, a rack 92, and a cylinder 93. The gear 91 is located inside the base 5 and is fitted onto the lower part of the shaft 51. That is, the gear 91 can rotate relative to the base 5 along with the shaft 51. The rack 92 is movably inserted through the lower part of the base 5 and meshes with the gear 91 inside the base 5. The cylinder 93 is located on the displacement seat 3 and its telescopic end is connected to one end of the rack 92. The cylinder 93 pulls or pushes the rack 92 to move linearly relative to the base 5, thereby causing the gear 91 to rotate clockwise or counterclockwise, thus realizing the rotation of the working pressure roller 7 on the rotating plate 6. In the initial state, the end face of the working pressure roller 7 is facing the rotating clamping end face of the rotating clamping module 2. In the folded state, the working pressure roller 7 rotates 90°, and the tangent of the outer peripheral surface of the working pressure roller 7 is parallel to the rotating clamping end face of the rotating clamping module 2. The main function is to use the transmission of gears and racks to convert the linear motion of the cylinder into the angular rotation of the rotating plate. This is more stable than the method of the cylinder directly pushing and pulling the rotating plate, and avoids the drift of the rotating plate's rotation angle.

[0029] Based on the above technical solution, a blocking block 31 is set on the displacement seat 3. The blocking block 31 is directly opposite the end of the rack 92. The maximum stroke of the rack is limited by this blocking block to protect the normal operation of the gear rack system. When the rack contacts the blocking block, it also indicates that the rotation action of the working pressure roller on the rotating seat has been completed and the folding working state has been entered.

[0030] Furthermore, a push screw 32 is provided on the blocking block 31 by means of a threaded connection. The push screw 32 can abut against the end of the rack 92, so that the push screw becomes adjustable and replaces the blocking block in contact with the end of the rack. This is beneficial for quickly adjusting the limiting distance of the push screw to the rack for different kit sizes.

[0031] like Figure 3 As shown, one end of the rack 92 is connected to the telescopic end of the cylinder component 93 via a balance block 94. The bottom end of the balance block 94 is provided with a rotatable guide roller 95, and a guide slide 33 is provided on the top surface of the displacement seat 3 to allow the guide roller 95 to move linearly. The cooperation between the guide roller and the guide slide constrains the direction of the rack's movement trajectory, ensuring the linearity of the rack's movement.

[0032] like Figure 2As shown, a rotatable pulley 61 is provided at the bottom of the rotating plate 6, and an arc-shaped guide groove 34 is provided on the top surface of the base 5. The pulley 61 is located in the guide groove 34 and can move along the path of the guide groove 34. The center of the guide groove 34 is consistent with the rotation center of the shaft 51. When the rotating plate 6 rotates relative to the base 5, the pulley 61 on the rotating plate 6 will also move accordingly along the trajectory of the guide groove 34. The cooperation between the pulley and the guide groove ensures the stability of the rotating plate's rotation and prevents the working pressure roller from deviating.

[0033] It should also be noted that the working pressure roller 7 is detachable. That is, a protruding screw 71 is provided on one side of the working pressure roller 7. The screw 71 passes through the adapter body 8 and is fastened by a nut 72. In this way, the working pressure roller is fixed on the adapter body. When the working pressure roller is worn to the point of being unusable, it can be removed to facilitate the replacement of new parts.

[0034] In this embodiment, the semi-automatic folding mechanism is used as follows: The operator places the magnetic steel kit into the rotating clamping end of the rotating clamping module 2, clamping the magnetic steel kit laterally; the displacement seat 3 adjusts its position via the linear driver 4, so that the working pressure roller 7 on it is approximately close to the edge of the magnetic steel kit that needs to be folded; the rotating plate 6 rotates via the drive structure 9, adjusting the angle of the working pressure roller 7 on it, so that the wheel surface of the working pressure roller 7 can contact the outwardly protruding edge of the magnetic steel kit to be folded, and the working pressure roller 7 continuously applies a certain pressure to the edge of the magnetic steel kit; at the same time, the rotating clamping module... Group 2 drives the magnet assembly to rotate. As the magnet assembly rotates, its edge passes under the surface of the fixed-position working pressure roller 7. The pressure applied by the working pressure roller 7, in conjunction with the rotation of the magnet assembly, gradually and continuously bends the edge of the magnet assembly into an inwardly tapering fold. After the magnet assembly rotates one revolution, the folding is complete, the rotary clamping module 2 stops rotating, and the linear driver 4 drives the displacement seat 3 to retract, causing the working pressure roller 7 to leave the magnet assembly and return to its initial position. The operator then removes the workpiece and repeats the above actions.

[0035] 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.
