Description

Technical Field

[0001] This utility model relates to the field of emulsion pump assembly technology, and in particular to a dual servo locking pusher mechanism for emulsion pump assembly. Background Technology

[0002] In the assembly of emulsion pumps, the locking of the pump head is one of the key processes. Traditional pump head locking mechanisms often use a single power source or simple mechanical transmission, making it difficult to precisely control the rotation and pressing actions during the locking process. This leads to numerous problems in actual production, such as incomplete locking of the pump head threads, affecting the pump's sealing and performance; damage to the threads during locking, resulting in product scrap; and excessive or insufficient locking torque, failing to meet product quality requirements. Therefore, there is an urgent need for a mechanism that can precisely control the pump head locking action, improving locking quality and stability. Summary of the Invention

[0003] The purpose of this invention is to provide a dual servo locking mechanism for emulsion pump assembly, which enables precise locking of the emulsion pump pump head.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dual-servo locking pusher mechanism for assembling an emulsion pump, comprising a first servo motor, a second servo motor, a rotary transmission assembly, an upper push transmission assembly, a locking mold, and a mounting frame; the first servo motor is connected to the locking mold via the rotary transmission assembly and is used to drive the locking mold to rotate; the second servo motor is connected to the locking mold via the upper push transmission assembly and is used to drive the locking mold to move up and down; the locking mold is used to complete the locking of the emulsion pump pusher, and the mounting frame is used to support and fix the various components.

[0005] Optionally, the rotary transmission assembly includes a synchronous wheel set and a transmission shaft, the output shaft of the first servo motor is connected to the synchronous wheel set, and the synchronous wheel set is connected to the locking mold through the transmission shaft.

[0006] Optionally, the upper drive assembly includes a push rod and a guide rail pair, the output shaft of the second servo motor is connected to the push rod, the push rod is fixedly connected to the locking mold, the guide rail pair includes a guide rail and a cam, the guide rail is fixed on the mounting frame, and the cam is connected to the locking mold.

[0007] Optionally, it also includes a torque detection device, which is disposed between the locking mold and the rotary transmission assembly, for real-time detection of the torque when the push head is locked, and for transmitting the detection signal to an external control system.

[0008] Optionally, the torque detection device includes a torque sensor, which is mounted on the connecting shaft between the guide rail pair and the locking mold.

[0009] Optionally, the working surface of the locking mold is provided with a positioning groove and a locking tooth guide structure that are adapted to the shape of the emulsion pump nozzle.

[0010] Compared with existing technologies, the dual-servo locking pusher mechanism for emulsion pump assembly provided by this utility model uses dual servo motors to independently control the rotation and up-and-down movement, which can precisely match the speed and force of rotation and pressing during the pusher locking process to improve the locking accuracy. The first servo motor precisely controls the rotation angle and speed of the locking mold through the synchronous wheel set and transmission shaft, so that the pusher teeth are accurately aligned; the second servo motor, with the help of the push rod and guide rail pair, combined with the cam structure optimized pressing trajectory, ensures that the pusher is subjected to stable and precise downward pressure during locking, effectively avoiding problems such as tooth misalignment, incomplete locking or excessive tightness, greatly improving the locking accuracy of the pusher, ensuring the sealing and stability of the emulsion pump product, and the positioning groove and locking tooth guide structure on the locking mold further assist in improving the locking accuracy. The positioning groove ensures the pusher head is accurately positioned before locking, reducing locking defects caused by positional deviations. The locking tooth guide structure guides the teeth to mesh smoothly, reducing errors during the locking process and improving product consistency and yield. It also improves production efficiency. The use of transmission components such as the synchronous pulley set and guide rail pair makes the rotation and vertical movement of the locking mold smoother and more efficient. The synchronous pulley set has an accurate transmission ratio and can quickly respond to the commands of the first servo motor, enabling rapid rotation of the pusher head. The guide rail pair and cam structure ensure smooth vertical movement of the locking mold, shortening the pusher head locking time. Furthermore, the real-time feedback from the torque detection device and the intelligent adjustment of the control system reduce downtime and debugging time caused by locking problems, further improving production efficiency and making it suitable for large-scale automated production of emulsion pumps.

[0020] Please see Figure 1 and Figure 2The dual-servo locking pusher mechanism for assembling an emulsion pump provided in this embodiment includes a first servo motor 1, a second servo motor 2, a rotary transmission assembly 3, an upper push transmission assembly 4, a locking mold 5, and a mounting frame 6. The first servo motor 1 is connected to the locking mold 5 through the rotary transmission assembly 3 and is used to drive the locking mold 5 to rotate. The second servo motor 2 is connected to the locking mold 5 through the upper push transmission assembly 4 and is used to drive the locking mold 5 to move up and down. The locking mold 5 is used to lock the emulsion pump pusher, and the mounting frame 6 is used to support and fix the components.

[0021] In this application, the rotary transmission assembly 3 includes a synchronous wheel set 31 and a transmission shaft 32. The output shaft of the first servo motor 1 is connected to the synchronous wheel set 31, and the synchronous wheel set 31 is connected to the locking mold 5 through the transmission shaft 32.

[0022] In this application, the upper transmission assembly 4 includes a push rod 41 and a guide rail pair 42. The output shaft of the second servo motor 2 is connected to the push rod 41. The push rod 41 is fixedly connected to the locking mold 5. The guide rail pair 42 includes a guide rail and a cam. The guide rail is fixed on the mounting frame 6, and the cam is connected to the locking mold 5.

[0023] This application also includes a torque detection device, which is disposed between the locking mold 5 and the rotary transmission assembly 3, for real-time detection of the torque when the push-button is locked, and transmits the detection signal to an external control system.

[0024] In this application, the torque detection device includes a torque sensor, which is mounted on the connecting shaft between the guide rail pair 42 and the locking mold 5.

[0025] In this application, the working surface of the locking mold 5 is provided with a positioning groove and a locking tooth guide structure that are adapted to the shape of the emulsion pump nozzle.

[0026] In practice: During the assembly of the emulsion pump head, the emulsion pump body and the head to be locked are first placed in the designated workstation. The operator presets the locking torque threshold, the rotation parameters of the first servo motor 1 (such as speed and rotation angle), and the pressing parameters of the second servo motor 2 (pressing speed and stroke) through the external control system. After the mechanism is started, the first servo motor 1 operates, transmitting power to the locking mold 5 through the synchronous pulley set 31 and the transmission shaft 32, driving the locking mold 5 to rotate, which in turn drives the head to rotate, so that the threads are initially aligned. At the same time, the second servo motor 2 starts, and the push rod 41 pushes the locking mold 5 downward along the guide rail pair 42 under the motor drive. The cam structure assists in adjusting the pressing trajectory, so that the locking mold 5 presses down the head smoothly. During this process, the torque sensor installed on the connecting shaft detects the locking torque in real time and feeds the signal back to the control system. When the detected torque approaches the preset threshold, the control system fine-tunes the operating parameters of the first servo motor 1 and the second servo motor 2 to ensure that the threads of the head are accurately engaged and the locking force is moderate. If the torque exceeds the threshold, the control system immediately reduces the motor speed or the downward pressure to prevent damage to the threads; if the torque is insufficient, the power output is increased to ensure locking quality; after locking is completed, the second servo motor 2 rotates in reverse, driving the locking mold 5 to rise and reset along the guide rail pair 42, waiting for the next locking task. Throughout the process, the positioning groove and locking tooth guide structure on the working surface of the locking mold 5 continuously play their role, ensuring accurate positioning of the pusher and smooth engagement of the threads; this utility model achieves high-precision and high-efficiency locking of the emulsion pump pusher through the coordinated drive of dual servo motors, precise transmission components, and real-time torque detection, effectively improving product quality and production efficiency, and is suitable for mass production on automated production lines for emulsion pumps.

[0027] As can be seen from the structure and specific implementation process of the dual servo locking pusher mechanism for emulsion pump assembly described above, the dual servo locking pusher mechanism for emulsion pump assembly provided in this application can improve the shrinkage accuracy. The dual servo motors independently control the rotation and up-and-down movement, which can accurately match the speed and force of rotation and pressing during the pusher locking process. The first servo motor 1 precisely controls the rotation angle and speed of the locking mold 5 through the synchronous wheel set 31 and the transmission shaft 32, so that the pusher teeth are accurately aligned; the second servo motor 2, with the help of the push rod 41 and the guide rail pair 42, combined with the cam structure optimized pressing trajectory, ensures that the pusher is subjected to stable and precise downward pressure during locking, effectively avoiding the problems of tooth misalignment, incomplete locking or excessive tightness, greatly improving the locking accuracy of the pusher, ensuring the sealing and stability of the emulsion pump product, and the positioning groove and locking tooth guide structure on the locking mold 5 further assist in improving the locking accuracy. The positioning groove ensures the pusher head is accurately positioned before locking, reducing locking defects caused by positional deviations. The locking tooth guide structure guides the teeth to mesh smoothly, reducing errors during the locking process and improving product consistency and yield. It also improves production efficiency. The use of transmission components such as the synchronous pulley set 31 and guide rail pair 42 makes the rotation and vertical movement of the locking mold 5 more stable and efficient. The synchronous pulley set 31 has an accurate transmission ratio and can quickly respond to the commands of the first servo motor 1, enabling rapid rotation of the pusher head. The guide rail pair 42 and cam structure ensure smooth vertical movement of the locking mold 5, shortening the pusher head locking time. Furthermore, the real-time feedback from the torque detection device and the intelligent adjustment of the control system reduce downtime and debugging time caused by locking problems, further improving production efficiency and making it suitable for large-scale automated production of emulsion pumps.
