Description

Technical Field

[0001] This invention relates to the field of transmission device technology, and in particular to a modular and detachable electromechanical transmission device. Background Technology

[0002] In many fields such as modern industrial production, intelligent manufacturing, and transportation, electromechanical transmission devices, as core components for power transmission and motion control, directly affect the operating efficiency, stability, and reliability of the entire equipment system. With the continuous improvement of industrial automation, equipment places increasingly higher demands on the modularity, ease of assembly and disassembly, and smoothness of speed regulation of transmission devices. In traditional electromechanical transmission devices, couplings, as key components connecting the power source and the actuator, are often cumbersome to install and disassemble. Conventional couplings typically use bolt fastening or key connections, requiring various tools for step-by-step operation during assembly and disassembly. This is not only time-consuming but can also lead to decreased connection accuracy and affect transmission stability due to improper operation. Furthermore, some couplings have inadequately designed limit structures, which can easily fail under long-term high-speed operation or fluctuating loads. This can cause equipment vibration, increased noise, and even component damage, severely restricting the continuous and stable operation of the equipment. On the other hand, as the core component for adjusting the transmission ratio, the smoothness of the gearbox's speed regulation is crucial to the operating performance of the equipment. Traditional gearboxes often exhibit noticeable jerking during speed regulation due to limitations in gear meshing methods and shifting mechanism design. This jerking not only affects the stability of equipment operation and increases mechanical wear, but may also impact the load end, reducing the equipment's service life and working accuracy.

[0003] To address the shortcomings of existing electromechanical transmission devices in terms of ease of coupling assembly and disassembly, and smoothness of gearbox speed change, we propose a modular and detachable electromechanical transmission device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular and detachable electromechanical transmission device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A modular, detachable electromechanical transmission device includes a transmission box, with a transmission mechanism disposed inside the transmission box. The transmission mechanism includes a coupling cylinder, a lower rotating shaft, and an upper rotating shaft. Limiting slide columns are symmetrically slidably inserted into the upper and lower sides of the coupling cylinder. An annular groove is formed on the outer side of each limiting slide column. A tension spring is fixedly connected between the annular groove and the outer wall of the limiting slide column. Fixed seats are symmetrically fixedly connected to the upper and lower sides of the coupling cylinder. A horizontal cylinder is fixedly connected to the upper side of the fixed seats. Slide rods are slidably installed on both sides of the horizontal cylinder. A compression spring is fixedly connected between the inner ends of the two slide rods. Limiting holes are formed on the side walls of the limiting slide columns, and the ends of the slide rods are inserted into the inner sides of the limiting holes.

[0006] In this invention, three gear cylinders are fixedly installed on the outer side of the upper rotating shaft, several synchronous electric push rods are fixedly installed inside the gear cylinders, several insert rods are slidably installed on the left side of the gear cylinders, a spring is fixedly connected between the inner end of the insert rod and the output end of the synchronous electric push rod, and a metal ball is embedded in the outer end of the insert rod.

[0007] In this invention, an electrical communication component is provided on the right side of the upper rotating shaft. The electrical communication component includes a mounting base, which is screwed onto the inner wall of the transmission box. A slide cylinder is fixedly installed on the left side of the mounting base, and a slide column is slidably installed on the inner side of the slide cylinder. A metal spring is fixedly connected between the bottom of the slide column and the inner side of the slide cylinder. An electric brush is fixedly connected to the outer end of the slide column, and the electric brush is electrically connected to the metal spring.

[0008] In this invention, a drive motor is screwed onto the outside of the transmission box, and the output end of the drive motor rotates through to the inside of the transmission box. The coupling sleeve is sleeved on the outside of the output end of the drive motor and the lower rotating shaft. Both the output end of the drive motor and the lower rotating shaft are provided with keyways adapted to the limiting slide column.

[0009] In this invention, a lower stabilizing bushing is rotatably mounted on the outer side of the lower rotating shaft. The lower stabilizing bushing is screwed onto the inner wall of the transmission box. A long groove is provided on the side wall of the cross cylinder. A lever is fixedly connected to the inner end of the slide rod. The lever slides through to the outer side of the long groove.

[0010] In this invention, a first gear, a second gear, and a third gear are sequentially fixedly installed on the outer wall of the lower rotating shaft.

[0011] In this invention, a first driven gear, a second driven gear, and a third driven gear are rotatably mounted on the upper rotating shaft in sequence. The first driven gear, the second driven gear, and the third driven gear mesh with the first gear, the second gear, and the third gear, respectively. The sides of the first driven gear, the second driven gear, and the third driven gear are each provided with a plurality of insertion holes that are adapted to the insertion rod.

[0012] In this invention, an upper stabilizing bushing is rotatably mounted on the outer side of the upper rotating shaft, and the upper stabilizing bushing is screwed onto the inner wall of the transmission box. The upper rotating shaft rotates through to the outer side of the transmission box.

[0013] In this invention, a metal contact electrode is fixedly installed on the right side of the upper rotating shaft, and the metal contact electrode abuts against the brush.

[0014] In this invention, a control circuit board and a power interface are fixedly installed on the side wall of the transmission box, and a top cover is screwed onto the upper side of the transmission box.

[0015] Compared with related technologies, the modular and detachable electromechanical transmission device proposed in this invention has the following advantages: In this invention, a modular, detachable electromechanical transmission device is provided. Through a coupling sleeve, when connecting the output end of the drive motor and the lower rotating shaft, first, a lever is squeezed to disengage the end of the sliding rod from the limiting hole of the limiting slide column, thus granting the limiting slide column sliding freedom. Then, both the output end of the drive motor and the end of the lower rotating shaft are inserted into the inner side of the coupling sleeve. Under the abutting action of the output end of the drive motor or the end of the lower rotating shaft, the limiting slide column slides outward. When the keyway on the side wall of the drive motor output end and / or the lower rotating shaft aligns with the inner end of the limiting slide column, the return force of the tension spring causes each limiting slide column to insert into its corresponding keyway, completing the connection between the drive motor output end and the lower rotating shaft. After the limiting slide column is inserted into the keyway, the lever is released. Under the rebound force of the compression spring, the end of the slide rod is inserted into the limiting hole on the side of the limiting slide column, thus limiting the sliding freedom of the limiting slide column. This prevents the tension spring from loosening due to the centripetal force during high-speed rotation, which would lead to instability in the connection of the limiting slide column. When disassembly is required, the principle is the same, and the process is reversed. The coupling cylinder set in this invention is quicker to install and disassemble than traditional couplings. At the same time, the limiting stability of the limiting slide column is guaranteed, making the connection and transmission process more stable. Furthermore, the components on the coupling cylinder are symmetrically arranged, which reduces the eccentric force during high-speed rotation and further improves the transmission stability.

[0016] In this invention, a modular, detachable electromechanical transmission device is provided. Three driven gears, meshing with a lower shaft, are mounted on an upper rotating shaft via a transmission cylinder. All three driven gears are rotatably connected to the upper rotating shaft. The three transmission cylinders are respectively located on the sides of the three driven gears. When it is necessary to change the rotation ratio between the lower and upper rotating shafts, only the driven gear with the desired ratio needs to be engaged. The synchronous electric push rod inside the transmission cylinder on the side of the driven gear is activated. A spring pushes a rod closer to the driven gear, causing the end of the rod to abut against the side of the driven gear. At this time, the spring is compressed. When the side of the driven gear opens... When the insertion hole and the end of the insertion rod are aligned, the spring's rebound force causes the insertion rod to quickly insert into the inner side of the insertion hole, achieving the docking of the gearbox and the driven gear. Since the gearbox is fixedly mounted on the side wall of the upper rotating shaft, it can transmit torque to the docked driven gear. Due to the spring, the end of the insertion rod remains in a charged insertion state, allowing it to be quickly inserted into the insertion hole after alignment. In addition, a metal spring is installed on the outer end of the insertion rod, reducing the friction between the end of the insertion rod and the side wall of the driven gear, thereby reducing the jerking sensation during gear ratio adjustment, making the gearbox's speed adjustment smoother, and enhancing practicality.

[0017] In this invention, a modular and detachable electromechanical transmission device is provided. Through the setting of an electrical connection component, the restoring force of a metal spring in the electrical connection component drives the brush installed at the end of the sliding column to always abut against the metal connection electrode at the right end of the upper rotating shaft, thereby realizing the electrical connection of the rotating body. This facilitates the control and power supply of the synchronous electric push rod on the upper rotating shaft. The operator can control the output transmission ratio inside the transmission box in real time from the outside, realizing the automated control function of the transmission box, making it more convenient to use.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] First embodiment: Please refer to the reference. Figures 1-8In the first embodiment of the present invention, a modular and detachable electromechanical transmission device includes a transmission box 1, and a transmission mechanism 6 is provided inside the transmission box 1. The transmission mechanism 6 includes a coupling cylinder 61, a lower rotating shaft 62, and an upper rotating shaft 67. Limiting slide columns 614 are symmetrically slidably inserted into the upper and lower sides of the coupling cylinder 61. An annular groove 615 is provided on the outer side of the limiting slide column 614. A tension spring 616 is fixedly connected between the annular groove 615 and the outer wall of the limiting slide column 614. Fixed seats 618 are symmetrically fixedly connected to the upper and lower sides of the coupling cylinder 61. A horizontal cylinder 619 is fixedly connected to the upper side of the fixed seat 618. Slide rods 620 are slidably installed on both sides of the horizontal cylinder 619. A compression spring 621 is fixedly connected between the inner ends of the two slide rods 620. Limiting holes 614 are provided on the side wall of the limiting slide column 614. 17. The end of the slide rod 620 is inserted into the inner side of the limiting hole 617. The lower stabilizing bushing 63 is rotatably installed on the outer side of the lower rotating shaft 62. The lower stabilizing bushing 63 is screwed onto the inner wall of the transmission box 1. A long groove 622 is opened on the side wall of the cross cylinder 619. A lever 623 is fixedly connected to the inner end of the slide rod 620. The lever 623 slides through to the outer side of the long groove 622. The first gear 64, the second gear 65 and the third gear 66 are fixedly installed on the outer wall of the lower rotating shaft 62 in sequence. The drive motor 4 is screwed onto the outer side of the transmission box 1. The output end of the drive motor 4 rotates through to the inner side of the transmission box 1. The coupling cylinder 61 is sleeved on the output end of the drive motor 4 and the outer side of the lower rotating shaft 62. A keyway adapted to the limiting slide rod 614 is opened on both the output end of the drive motor 4 and the lower rotating shaft 62.

[0022] With the above-described configuration, in this invention, when it is necessary to connect the output end of the drive motor 4 to the lower rotating shaft 62, first squeeze the lever 623. At this time, the slide rod 620 moves outward along the horizontal cylinder 619 under the drive of the lever 623, the compression spring 621 is compressed, and the end of the slide rod 620 exits the limiting hole 617 on the limiting slide post 614, so that the limiting slide post 614 obtains sliding freedom. Subsequently, both the output end of the drive motor 4 and the end of the lower rotating shaft 62 are inserted into the coupling cylinder 6. 1. On the inner side, under the abutment action of the output end of the drive motor 4 or the end of the lower rotating shaft 62, the limiting slide column 614 slides outward along the annular groove 615, and the tension spring 616 is stretched. When the keyway on the side wall of the output end of the drive motor 4 or the lower rotating shaft 62 is aligned with the inner end of the limiting slide column 614, the tension spring 616 is reset under the action of the pull force, which drives each limiting slide column 614 to be inserted into its corresponding keyway, thus initially completing the connection between the output end of the drive motor 4 and the lower rotating shaft 62. After the limiting slide column 614 is inserted into the keyway, the lever 623 is released. Under the action of the rebound force, the compression spring 621 pushes the slide rod 620 to move inward along the cross cylinder 619, so that the end of the slide rod 620 is re-inserted into the inner side of the limiting hole 617 on the side of the limiting slide column 614, thereby restricting the sliding freedom of the limiting slide column 614. This design can effectively prevent the centripetal force from causing the tension spring 616 to loosen during high-speed rotation, thereby avoiding the problem of unstable connection of the limiting slide column 614. When disassembly is required, the operating principle is the reverse of the connection process: squeeze the lever 623 to make the slide bar 620 exit the limiting hole 617, then pull out the limiting slide bar 614, and then pull out the output end of the drive motor 4 and the lower rotating shaft 62 from the inside of the coupling cylinder 61. The limiting slide bar 614 is reset under the action of the tension spring 616, and the disassembly is completed. Compared with traditional couplings, the coupling cylinder 61 of this invention allows for faster installation and disassembly. At the same time, the cooperation between the slide rod 620 and the limiting hole 617 effectively ensures the limiting stability of the limiting slide rod 614, thus ensuring the stability of the connection and transmission process. In addition, all components on the coupling cylinder 61 are symmetrically arranged, which can significantly reduce the eccentric force during high-speed rotation and further improve the transmission stability.

[0023] Specifically, a control circuit board 2 and a power interface 3 are fixedly installed on the side wall of the transmission box 1, and a top cover 5 is screwed onto the upper side of the transmission box 1.

[0024] With the above-described configuration, the top cover 5 can be removed, facilitating the inspection and maintenance of the internal parts of the transmission box 1. The power interface 3 is used to connect the external power supply and control system, and the control circuit board 2 is used to receive external control commands to adjust the internal components of the transmission box 1.

[0025] Second embodiment: Please refer to the reference. Figure 9 , Figure 11 and Figure 12 In this embodiment, three gear cylinders 613 are fixedly installed on the outer side of the upper rotating shaft 67. Several synchronous electric push rods 624 are fixedly installed inside the gear cylinders 613. Several insert rods 625 are slidably installed on the left side of the gear cylinders 613. A spring 626 is fixedly connected between the inner end of the insert rod 625 and the output end of the synchronous electric push rod 624. A metal ball 627 is embedded in the outer end of the insert rod 625. A first driven gear 610, a second driven gear 611, and a third driven gear 612 are rotatably installed on the upper rotating shaft 67 in sequence. The first driven gear 610, the second driven gear 611, and the third driven gear 612 mesh with the first gear 64, the second gear 65, and the third gear 66, respectively. Several insertion holes adapted to the insert rods 625 are opened on the sides of the first driven gear 610, the second driven gear 611, and the third driven gear 612.

[0026] Through the above-described configuration, the transmission ratio between the lower shaft 62 and the upper shaft 67 is conveniently adjusted via the gearbox 613. Specifically, three driven gears are mounted on the upper shaft 67: a first driven gear 610, a second driven gear 611, and a third driven gear 612. These three driven gears mesh with the first gear 64, the second gear 65, and the third gear 66 on the lower shaft 62, forming three different transmission ratios. All three driven gears are rotatably connected to the upper shaft 67. Three coupling cylinders 61 are respectively located on the sides of the three driven gears. When it is necessary to change the rotation ratio between the lower shaft 62 and the upper shaft 67, only the driven gear with the corresponding transmission ratio needs to be engaged, while the other driven gears remain disconnected from the gearbox 613 on their sides. When engaging a driven gear, the synchronous electric push rod 624 inside the gearbox 613 on the side of the driven gear is activated. The synchronous electric push rod 624 operates by pushing the insertion rod 625 closer to the driven gear via the spring 626, so that the end of the insertion rod 625 abuts against the side of the driven gear. At this time, the spring 626 is compressed. When the insertion hole on the side of the driven gear is aligned with the end of the insertion rod 625, the insertion rod 625 is quickly inserted into the inner side of the insertion hole under the rebound force of the spring 626, realizing the engagement of the gearbox 613 and the driven gear. Since the gearbox 613 is fixedly installed on the side wall of the upper rotating shaft 67, the gearbox 613 can transmit torque to the engaged driven gear, thereby driving the upper rotating shaft to rotate according to the transmission ratio of the gear set. The smooth adjustment of the transmission ratio is due to the spring 626. The end of the plug rod 625 can remain in a charged insertion state, ensuring that the insertion can be completed quickly after aligning with the insertion hole. In addition, a metal ball 627 is installed at the end of the plug rod 625. This design reduces the friction between the end of the plug rod 625 and the side wall of the driven gear, thereby reducing the jerking sensation during the adjustment of the transmission ratio, making the speed adjustment of the transmission box 1 smoother and enhancing the practicality of the device. Specifically, an upper stabilizing bushing 68 is rotatably mounted on the outer side of the upper rotating shaft 67. The upper stabilizing bushing 68 is screwed onto the inner wall of the transmission box 1, and the upper rotating shaft 67 rotates through to the outer side of the transmission box 1.

[0027] By setting the upper stabilizing bushing 68 in the above manner, the upper rotating shaft 67 rotates more smoothly.

[0028] Third embodiment: Please refer to the reference. Figure 10In this embodiment, an electrical communication component 7 is provided on the right side of the upper rotating shaft 67. The electrical communication component 7 includes a mounting base 71, which is screwed onto the inner wall of the transmission box 1. A slide cylinder 72 is fixedly installed on the left side of the mounting base 71. A slide column 73 is slidably installed on the inner side of the slide cylinder 72. A metal spring 74 is fixedly connected between the bottom of the slide column 73 and the inner side of the slide cylinder 72. A brush 75 is fixedly connected to the outer end of the slide column 73. The brush 75 is electrically connected to the metal spring 74. A metal connecting electrode 69 is fixedly installed on the right side of the upper rotating shaft 67. The metal connecting electrode 69 abuts against the brush 75.

[0029] Through the above-described configuration, the electrical connection problem in the rotating state is successfully solved by the carefully designed electrical connection component 7, providing reliable power and signal transmission guarantee for the automatic control of the device. The electrical connection component 7 is mainly composed of a mounting base 71, a sliding cylinder 72, a sliding column 73, a metal spring 74, and a brush 75. The components work together to ensure the stable transmission of power and control signals. Specifically, the mounting base 71 provides a stable mounting foundation for the entire electrical connection assembly 7, enabling it to be stably fixed in the corresponding position of the transmission box 1. The slide cylinder 72 is mounted on the mounting base 71, providing a guiding function for the sliding of the slide column 73, ensuring that the slide column 73 can only move in the direction of the metal contact electrode 69. The slide column 73 is located inside the slide cylinder 72, with a brush 75 installed at one end and the other end connected to a metal spring 74. One end of the metal spring 74 is fixed inside the slide cylinder 72, and the other end is connected to the slide column 73. In its natural state, the metal spring 74 is in a slightly compressed state, thereby generating a continuous rebound force. During device operation, the upper rotating shaft 67 rotates, and the metal contact electrode 69 at its right end also rotates with it. The brush 75 in the electrical connection assembly 7 needs to maintain constant contact with the metal contact electrode 69 to achieve electrical connection. At this time, the restoring force of the metal spring 74 plays a crucial role, continuously driving the slide column 73 along the slide cylinder 72 towards the upper rotating shaft 67, thus ensuring that the brush 75 installed at the end of the slide column 73 remains firmly in contact with the metal contact electrode 69 at the right end of the upper rotating shaft 67. This design ensures stable electrical connection, which is essential for the control and power supply of the synchronous electric actuator 624 on the upper rotating shaft 67. The synchronous electric actuator 624 is the core actuator for speed regulation, and its operation requires a stable power supply and real-time control signals. Through the electrical path established by the electrical connection component 7, external control signals can be transmitted to the synchronous electric push rod 624 in a timely manner, and electricity can also be continuously supplied to it to ensure that the synchronous electric push rod 624 can move precisely according to the control command and complete the docking or disengagement operation of the insertion rod 625 and the driven gear.
