Description

Technical Field

[0001] This utility model specifically relates to the field of motor stator processing technology, and more specifically to a positioning and pushing device for a motor stator. Background Technology

[0002] The positioning and pushing device for motor stators is a key piece of equipment on the automated production line for motors. It is mainly used to accurately position the motor stators and push them to the subsequent processes along a specified path. The stator is generally made by stacking multiple silicon steel sheets in sequence and then applying axial pressure through a riveting machine to make the silicon steel sheets fit tightly together. After riveting, the motor stator needs to be moved onto the conveyor using a pushing mechanism.

[0003] However, in practice, it has been noted that most current pushing mechanisms require manual control of the extension length of the grippers to keep the stator as centered as possible. Furthermore, different sizes of clamps are required when clamping stators of different sizes, which leads to higher costs. Utility Model Content

[0004] The purpose of this invention is to provide a positioning and pushing device for a motor stator. A contact trigger at the end of the stator holder automatically activates based on the pressure applied when in contact with the motor stator, thereby automatically clamping the stator. Furthermore, in conjunction with the lifting of a lifting cylinder and the rotation of a rotary motor, the stator is automatically fed into the device. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-8 This utility model provides a positioning and pushing device for a motor stator, including a motor stator riveting machine frame 1. A mounting bracket 6 is fixedly connected to one side of the motor stator riveting machine frame 1. A rotating material changing plate 7 is provided above the mounting bracket 6, and stator clamps 9 are movably connected to both ends of the rotating material changing plate 7.

[0031] The rotating material changing plate 7 includes a lifting horizontal plate 74 and a rotating mounting plate 71 arranged parallel to each other. The lifting horizontal plate 74 is located below the rotating mounting plate 71. A rotating motor 72 is fixedly connected to the bottom of the lifting horizontal plate 74. One end of the rotating motor 72 passes through the lifting horizontal plate 74 and is fixedly connected to the rotating mounting plate 71.

[0032] Furthermore, both ends of the rotating mounting plate 71 are fixedly connected to mounting upright plates 73, and a movable cylinder 8 is fixedly connected to one side of the mounting upright plate 73. The end of the movable cylinder 8 passes through the mounting upright plate 73 and is fixedly connected to the stator clamp 9.

[0033] By adopting the above technical solution, the rotating motor 72 below the lifting horizontal plate 74 drives the rotating mounting plate 71 to rotate, and then the stator clamps 9 at both ends clamp the motor stator. After conversion, the rotating motor 72 drives the rotating mounting plate 71 to reset, preventing the wires from being entangled and damaged.

[0034] Furthermore, the stator clamp 9 includes a connecting main board 91 fixedly connected to the end of the movable cylinder 8, and symmetrical gear rocker arms 94 are movably connected to both sides of the connecting main board 91. Each side of the symmetrical gear rocker arm 94 is movably connected to an anti-slip gripper 95 at the end away from the connecting main board 91.

[0035] More specifically, the side of the anti-slip gripper 95 is movably connected to a connecting rocker arm 96, and the end of the connecting rocker arm 96 away from the anti-slip gripper 95 is movably connected to the connecting main board 91. The end of the connecting main board 91 near the moving cylinder 8 is fixedly connected to a clamping motor 93, and the end of the clamping motor 93 is engaged with the gear rocker arm 94 for transmission.

[0036] Furthermore, the end of the connecting motherboard 91 is symmetrically fixedly connected to a limiting slide bar 92, and the other end of the limiting slide bar 92 passes through the mounting plate 73. The end of the connecting motherboard 91 away from the limiting slide bar 92 is also movably connected to a contact trigger 97.

[0037] Furthermore, the contact trigger 97 includes a U-shaped slide block 971 that slides with the main board 91, and a locking screw is threaded at the connection point. An adjusting screw 974 is threaded at the other end of the U-shaped slide block 971, and a connecting end plate 975 is movably connected to the end of the adjusting screw 974 away from the U-shaped slide block 971.

[0038] More specifically, the connecting end plate 975 is symmetrically fixedly connected to an extension slide rod 973 on the side near the U-shaped slide block 971, and the other end of the extension slide rod 973 is slidably engaged with the U-shaped slide block 971, while a pressure sensor 976 is embedded in the other end of the connecting end plate 975.

[0039] By adopting the above technical solution, the moving cylinder 8 pushes the stator clamp 9 to move closer to the stator. When the pressure sensor 976 in the stator clamp 9 comes into contact with the stator, the pressure sensor 976 will send a signal after being subjected to pressure, thereby controlling the output shaft of the clamping motor 93 to rotate. Through the transmission cooperation with the gear rocker 94, the stator is automatically clamped.

[0040] Furthermore, the mounting bracket 6 includes a support plate 61 fixedly connected to the side of the motor stator riveting machine frame 1, and a triangular bracket 62 is symmetrically fixedly connected between the support plate 61 and the motor stator riveting machine frame 1. A lifting cylinder 63 is symmetrically fixedly connected below the triangular bracket 62, and the end of the lifting cylinder 63 passes through the support plate 61 and is fixedly connected to the lifting plate 74.

[0041] By adopting the above technical solution, the lifting cylinder 63 pushes the rotating material changing plate 7 to move upward as a whole, and the rotating motor 72 on the rotating material changing plate 7 drives the rotating mounting plate 71 to rotate, thereby changing the stator clamped at both ends of the rotating mounting plate 71 and moving the riveted motor stator to the conveying mechanism.

[0042] Furthermore, one end of the gear rocker 94 is integrally provided with gear teeth, and the end of the clamping motor 93 is fixedly connected with a drive gear corresponding to the gear teeth. The drive gear meshes with the gear teeth at the end of the gear rocker 94, and the end of the gear rocker 94 swings when the clamping motor 93 rotates through the transmission connection.

[0043] Furthermore, both sides of the connecting motherboard 91 are symmetrically fixedly connected with limiting baffles corresponding to the U-shaped slide 971, and the limiting baffles are located on both sides of the U-shaped slide 971, which play a limiting role for the U-shaped slide 971.

[0044] By adopting the above technical solution, the locking screw at the end of the connecting main board 91 is loosened, the extension length of the U-shaped slide 971 is adjusted, and the adjusting screw 974 is rotated. By adjusting the threaded engagement between the screw 974 and the U-shaped slide 971, the position of the connecting end plate 975 is further adjusted so that it can be adjusted according to the size of the motor stator, and so that it can be adjusted according to different motor stator sizes.

[0045] The working principle of this utility model is as follows: In use, firstly, the motor stator riveting machine frame 1 is placed on one side of the conveying mechanism (not shown in the figure), and the mounting bracket 6 is installed between the motor stator riveting machine frame 1 and the transmission mechanism. Then, the moving cylinder 8 pushes the stator clamp 9 towards the motor stator. At this time, the anti-slip gripper 95 is in the open state. When the motor stator contacts the pressure sensor 976, the pressure sensor 976 will send a signal after being subjected to force, thereby controlling the clamping motor 93 to drive the gear rocker 94 to rotate. Through the gear rocker 94 and the connecting rocker... The interaction of the rods 96 causes the symmetrically arranged anti-slip grippers 95 to come together, thereby clamping the motor stator. Then, the lifting cylinder 63 pushes the lifting horizontal plate 74 upward, and the rotary motor 72 below the lifting horizontal plate 74 drives the rotating mounting plate 71 to rotate, thereby changing the position of the motor stator at both ends of the rotating mounting plate 71. After the change, the anti-slip grippers 95 are released, and then the rotary motor 72 rotates in the opposite direction to reset the rotating material changing plate 7, and the next operation is performed again. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
