The thrust output of the air cylinder and electric cylinder is very limited. For some wide and large winding machines, the oscillating action cannot be completed normally. Moreover, the thrust output of the air cylinder and electric cylinder is not completely stable. When encountering greater resistance, the oscillation distance will deviate. Summary of the Invention

Detailed Implementation

[0021] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, construction, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0022] This application provides a dual-push-rod type swing device, which is installed on a winding machine and is mainly used to drive the winding machine to perform precise left and right reciprocating swing.

[0023] like Figure 1-3 As shown, the entire swing device 100 is fixedly installed on the ground by a rectangular base plate 1. The swing device 100 includes a drive motor 2, a pair of swing components 3 and a pair of transmission shafts 4. The pair of transmission shafts 4 are respectively connected between the drive motor 2 and the pair of swing components 3, transmitting the power of the drive motor 2 to the pair of swing components 3, so that the winding machine swings back and forth in the left and right directions.

[0024] The drive motor 2 is mounted above the center of the base plate 1. In this embodiment, the drive motor 2 is a dual-output shaft motor, with its two output shafts 21 facing forward and backward respectively. An adjustment plate 5 parallel to the base plate 1 is fixedly mounted on the bottom of the drive motor 2. Four adjustment screws 6 are vertically mounted between the adjustment plate 5 and the base plate 1. The lower end of the adjustment screw 6 is fixedly or rotatably connected to the base plate 1, and the upper end passes through the adjustment plate 5 and is threaded into it. By tightening the nut on the adjustment screw 6 or directly rotating the screw, the vertical height of the adjustment plate 5 and the drive motor 2 fixed thereon can be precisely adjusted.

[0025] A pair of swing components 3 are symmetrically arranged on the front and rear sides of the drive motor 2. The output shaft 21 of the front side of the drive motor 2 is connected to the swing component 3 via a transmission shaft 4, and the output shaft 21 of the rear side of the drive motor 2 is connected to the swing component 3 via another transmission shaft 4. The dual-output-shaft drive motor 2 ensures the synchronous movement of the left and right swing components 3, thereby making the swing of the winding machine more stable and symmetrical. Each transmission shaft 4 is connected to the corresponding output shaft 21 by a coupling 9. The coupling can compensate for minor alignment errors between the motor's output shaft and the transmission shaft, and absorb vibrations and shocks during operation, ensuring the smooth operation of the device.

[0026] Each swing assembly 3 includes a fixed base 31 fixedly mounted on the base plate 1 and a movable lead screw 32 passing through the fixed base 31, the movable lead screw 32 extending in the left-right direction. The end of the movable lead screw 32 is connected to the winding machine via a connecting assembly 7. The connecting assembly 7 includes a fisheye connector 71 fixed to the end of the movable lead screw 32 and a connecting seat 72 fixedly connected to the winding machine. The fisheye connector 71 and the connecting seat 72 are connected by a pin 73 extending in the front-back direction. The fisheye connector provides a flexible universal joint connection, which can compensate for possible small angular and positional deviations between the winding machine and the movable lead screw during swing, reduce stress concentration at the connection, and improve the service life and smooth operation of the device.

[0027] Each fixed base 31 houses a worm gear assembly that drives the movable lead screw 32 and the corresponding drive shaft 4. The worm gear assembly includes a worm 311 extending in the front-rear direction and a worm wheel (not shown in the figure) coaxially mounted on the movable lead screw 32. Each worm 311 is connected to its corresponding drive shaft 4 by a clutch 8. The clutch includes a first clutch body 81 coaxially connected to the end of the drive shaft 4 and a second clutch body 82 coaxially connected to the end of the worm 311. The clutch allows for quick disengagement of the connection between the drive shaft 4 and the worm 311, increasing operational flexibility.

[0028] The worm gear 311 and worm wheel inside the fixed base 31 mesh with each other. The inner wall surface of the worm wheel is threadedly engaged with the moving lead screw 32. When the worm gear 311 rotates, the worm wheel rotates around its own axis, and the thread on its inner wall surface abuts against the thread on the surface of the moving lead screw 32, causing the moving lead screw 32 to move back and forth along its own axis during rotation. When the drive motor 2 drives a pair of transmission shafts 4 to rotate synchronously, each transmission shaft 4 drives the moving lead screw 32 to move in the left and right directions through the worm gear assembly, which in turn drives the winding machine to swing in the left and right directions. The worm gear drive has the characteristics of large transmission ratio, compact structure, smooth operation, low noise, and reverse self-locking. Its large transmission ratio can convert the high-speed rotation of the drive motor into high torque and low-speed linear motion of the moving lead screw, which is very suitable for driving the heavy-duty winding machine to swing smoothly. At the same time, the reverse self-locking characteristic can prevent the winding machine from moving accidentally due to external force in the non-drive state, thus improving safety.

[0029] When the drive motor 2 starts, its front and rear output shafts 21 drive a pair of transmission shafts 4 to rotate synchronously, transmitting power to the moving screws 32 of a pair of oscillating components 3. The pair of moving screws 32 move back and forth along their own axis, thereby driving the winding machine to oscillate back and forth in the left and right direction. By controlling the forward and reverse rotation and speed of the drive motor 2, the oscillation amplitude, speed and frequency of the winding machine can be adjusted.

[0030] The pair of swing components in this application are symmetrically driven by a drive motor, which can continuously and stably output lateral thrust and ensure that the winding machine is subjected to balanced force, swings smoothly and accurately. The device has good overall rigidity and large load capacity, and is suitable for industrial environments that require long-term continuous and stable operation.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
