Description

Technical Field

[0001] This utility model relates to the field of automated actuators, and in particular to a swing mechanism for automated equipment. Background Technology

[0002] In applications such as material mixing, experimental shaking tables, packaging material handling, food spreading, and automated conveying, reciprocating oscillating mechanisms are core components for achieving material homogenization, directional sorting, and quantitative conveying. Existing oscillating mechanisms mostly employ fixed crank structures, gear drives, or cylinder drives to achieve reciprocating oscillation. The fixed crank structure is currently the most widely used solution, driving the oscillating arm through a fixed eccentric shaft on the crank disc in conjunction with a connecting rod. It is simple in structure and low in cost. However, since the crank eccentricity is determined and fixed during the design and manufacturing stages, the oscillation angle is uniquely determined by the eccentricity and cannot be changed once finished. Gear-driven oscillating mechanisms convert rotational motion into reciprocating oscillation through gear pairs, offering high transmission accuracy and load-bearing capacity. Cylinder-driven oscillating mechanisms directly drive the oscillation of the oscillating arm using the extension and retraction of the cylinder piston rod, offering advantages such as compact structure and fast response.

[0003] However, the swing angle of a fixed crank structure is uniquely determined by the crank eccentricity, and the swing angle is fixed and cannot be adjusted. When the working scene or process parameters change, it is necessary to replace the crank with a different specification, resulting in poor adaptability and high cost. Gear transmission mechanisms have problems such as large transmission clearance and unstable operation, while cylinder drive methods have defects such as large impact and difficulty in speed adjustment, making it difficult to meet the requirements of high-precision swing operations. Existing mechanisms generally have defects such as poor speed adjustment accuracy, large operating vibration, easy wear, and cumbersome maintenance, making it difficult to meet the comprehensive operating requirements of multiple scenarios, high precision, and long service life. Utility Model Content

[0004] In order to overcome the shortcomings of existing technologies, such as fixed and non-adjustable swing angle leading to poor adaptability, large gear transmission clearance, large cylinder drive impact and difficulty in speed adjustment, this utility model provides a swing mechanism for automated equipment.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution: This utility model provides a swing mechanism for automated equipment, including a fixed base, a drive component installed on the fixed base, a crank transmission component connected to the output end of the drive component, the crank transmission component being hinged to the swing execution component, and a load connection end connected to one end of the swing execution component. The drive assembly includes a speed-regulating motor connected to the top of the fixed base. The output end of the speed-regulating motor is connected to the input end of the gearbox via a coupling. The output end of the gearbox extends horizontally. The crank transmission assembly includes a crank disc, an eccentric adjustment shaft, and a connecting rod. The crank disc is coaxially connected to the output end of the gearbox. The eccentric adjustment shaft is installed radially adjustable along the crank disc. One end of the connecting rod is hinged to the eccentric adjustment shaft. The swing actuator includes a swing arm and a swing shaft. The swing shaft is mounted on one side of a bearing support via a bearing. The swing arm is connected to the swing shaft. The other end of the connecting rod is hinged to the swing arm. A limiting module is provided on the side of the bearing support to limit the maximum swing angle of the rocker arm.

[0006] In this technical solution, by setting a radially adjustable eccentric adjustment shaft on the crank plate, any swing angle within the range of 0°–60° can be set as needed. It can adapt to the swing angle requirements of different working scenarios without replacing any parts, thus avoiding the situation where the fixed crank structure has a single swing angle and poor adaptability.

[0007] The drive design employs a speed-regulating motor and a gearbox. The speed of the speed-regulating motor is continuously adjustable, and the output is after the speed is reduced and the torque is increased by the gearbox.

[0009] In this technical solution, the drive components are supported by a motor mounting bracket, ensuring operational stability.

[0010] Preferably, the eccentric adjusting shaft is fixed in the radial groove of the crank disc by a locking nut.

[0013] In this technical solution, the load connection end is used to detachably connect to different load components such as material trays, mixing heads or conveying troughs, and different end actuators can be quickly replaced according to specific operation requirements to achieve rapid changeover.

[0014] Preferably, the limiting module includes two limiting blocks, which are respectively connected to both sides of the bearing support.

[0015] In this technical solution, the swing angle of the rocker arm is limited by a limit stop.

[0016] Preferably, the limiting module further includes two adjusting blocks, each adjusting block including a mounting base, the mounting base being connected to the side of the bearing support, the inner wall of the mounting base being connected to multiple guide shafts, and the surface of the guide shafts being slidably connected to a sliding plate; Both sides of the sliding plate are connected to elastic connectors, and the end of the elastic connector away from the sliding plate is connected to the inner wall of the mounting base. A support mounting block is connected to one side of the sliding plate, and a protective rubber pad is connected to one side of the support mounting block.

[0017] In this technical solution, the rocker arm is prevented from directly and rigidly colliding with the limiting module by adjusting the stop block, thereby reducing noise and avoiding damage to the hinge point and transmission components.

[0018] Preferably, a track bar is connected to one side of the mounting base, and a sliding groove is provided on the side of the support mounting block near the mounting base, through which the track bar is slidably connected to the support mounting block.

[0019] In this technical solution, the movement trajectory of structures such as support mounting blocks and sliding plates is limited by track bars.

[0020] Preferably, the rocker arm includes a fixed rocker arm, which is a strip structure of fixed length.

[0021] Preferably, the rocker arm further includes an adjustable rocker arm, which includes a central gear disposed inside the support housing. Both sides of the central gear are meshed with adjusting racks. The end of the adjusting rack away from the support housing is connected to a mounting platform. The mounting platforms on both sides are respectively connected to the swing shaft and hinged to the connecting rod. Both ends of the central gear are connected to adjustment knobs.

[0022] In this technical solution, the length of the adjustable swing arm can be adjusted.

[0023] Preferably, locking components are provided on both sides of the central gear. The locking components include a locking plate, which is slidably connected to a plurality of connecting side plates. Each connecting side plate is connected to a fixing post at both ends, and the side of the fixing post is connected to the inner wall of the supporting shell. When one side of the locking plate is in contact with the central gear, the locking plate engages. On the other side of the locking plate, multiple elastic reset members are connected, and one end of each elastic reset member is connected to the connecting side plate. The locking plate has multiple connecting strips connected to one side, and one end of each connecting strip is connected to one side of the locking plate. Both sides of the locking plate are detachably connected to the locking bolts and nuts.

[0024] In this technical solution, the angle of the central gear is locked by a locking component.

[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0026] The positive and progressive effects of this utility model are as follows: This invention, by setting a radially adjustable eccentric adjustment shaft on the crank plate, allows for setting any swing angle within the range of 0°–60° as needed. It can adapt to the swing angle requirements of different working scenarios without replacing any parts, thus avoiding the situation where the fixed crank structure has a single swing angle and poor adaptability.

[0027] The drive design employs a speed-regulating motor and a gearbox. The speed of the speed-regulating motor is continuously adjustable, and the output is after the speed is reduced and the torque is increased by the gearbox. There is no rigid or flexible impact during the transmission process, and the swinging action is smooth and reliable, which can meet the requirements of high-precision swinging operations.

[0028] The limit module effectively prevents overtravel oscillation, avoids component damage caused by excessive oscillation, reduces the wear rate of key components, and extends the service life of the oscillating mechanism.

[0029] This invention can absorb impact energy and reduce noise by adjusting the stop block, thereby reducing impact damage to hinge points, bearings and transmission components and significantly extending the overall service life of the mechanism.

[0030] Furthermore, the adjustable swing arm and locking assembly allow the swing arm length to be changed without changing the swing angle, thereby adjusting the linear stroke and linear velocity of the end load. This enables the same mechanism to be adapted to material trays or worktables of different sizes, further enhancing its versatility. Attached Figure Description

[0043] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments described herein.

[0044] Figures 1 to 12 The diagram shown is a structural schematic of an embodiment of the swing mechanism for automated equipment of this utility model.

[0045] A swing mechanism for automated equipment includes a fixed base 1, a drive assembly 2 is installed on the fixed base 1, a crank transmission assembly 3 is connected to the output end of the drive assembly 2, the crank transmission assembly 3 is hinged to the swing execution assembly 4, one end of the swing execution assembly 4 is connected to a load connection end 5, and one end of the load connection end 5 is rotatably connected to the fixed base 1. The drive assembly 2 includes a speed-regulating motor 21, which is connected to the top of the fixed base 1. The output end of the speed-regulating motor 21 is connected to the input end of the gearbox 23 via a coupling 22. The output end of the gearbox 23 extends horizontally. The speed-regulating motor 21 is fixed to the motor mounting base by bolts.

[0046] Gearbox 23 is a worm gear reducer.

[0047] The crank transmission assembly 3 includes a crank disc 31, an eccentric adjustment shaft 32, and a connecting rod 33. The crank disc 31 is coaxially connected to the output end of the gearbox 23. The eccentric adjustment shaft 32 is installed radially adjustable along the crank disc 31. One end of the connecting rod 33 is hinged to the eccentric adjustment shaft 32. The crank disc 31 has a T-shaped groove radially formed on its surface. The bottom of the eccentric adjustment shaft 32 is provided with a T-shaped slider that matches the T-shaped groove. The eccentric adjustment shaft 32 is inserted into the groove by the T-shaped slider and fixed in the desired position by a locking nut.

[0048] The swing actuator 4 includes a swing arm and a swing shaft 42. The swing shaft 42 is mounted on one side of the bearing support 43 via a bearing. The swing arm is connected to the swing shaft 42. The other end of the connecting rod 33 is hinged to the swing arm. The limit module is located on the side of the bearing support 43 and is used to limit the maximum swing angle of the rocker arm.

[0049] The limit module is located on the swing path of the rocker arm.

[0050] The speed-regulating motor 21 is an AC variable frequency speed-regulating motor or a DC speed-regulating motor, which is electrically connected to an external speed controller to adjust the motor speed and thus control the oscillation frequency.

[0051] In this technical solution, by setting a radially adjustable eccentric adjustment shaft 32 on the crank plate 31, any swing angle within the range of 0°–60° can be set as needed. It can adapt to the swing angle requirements of different working scenarios without replacing any parts, thus avoiding the situation where the fixed crank structure has a single swing angle and poor adaptability.

[0052] The drive design employs a speed-regulating motor 21 in conjunction with a reduction gearbox 23. The speed of the speed-regulating motor 21 is continuously adjustable. After being reduced in speed and increased in torque by the reduction gearbox 23, the output is generated. There is no rigid or flexible impact during the transmission process, and the swinging motion is smooth and reliable, which can meet the requirements of high-precision swinging operations.

[0053] The limit module effectively prevents overtravel oscillation, avoids component damage caused by excessive oscillation, reduces the wear rate of key components, and extends the service life of the oscillating mechanism.

[0054] The fixed base 1 is integrally formed, and the fixed base 1 is equipped with a motor mounting bracket and a bearing support 43.

[0055] In this technical solution, the drive components are supported by a motor mounting bracket, ensuring operational stability.

[0056] The fixed base 1 is made of cast iron in one piece. This design gives the fixed base 1 high rigidity and vibration resistance, which can effectively suppress the transmission of vibration during operation and reduce the relative displacement error between transmission components.

[0057] The motor mounting base is provided with a positioning stop and bolt holes for precise positioning and fixing of the speed-regulating motor 21; the bearing support 43 is provided with a pair of face-to-face angular contact ball bearings for supporting the swing shaft 42 and ensuring the rotational accuracy and axial positioning of the swing shaft.

[0058] The eccentric adjusting shaft 32 is fixed in the radial groove of the crank disc 31 by a locking nut.

[0059] In this technical solution, the sway angle can be infinitely adjusted within the range of 0° to 60° by changing the radial distance between the eccentric adjustment shaft 32 and the rotation center of the crank disk 31.

[0060] The load connection end 5 is connected to the end of the rocker arm. The load connection end 5 is a flange interface or a clamp interface.

[0061] In this technical solution, the load connection end 5 is used to detachably connect to different load components such as material trays, mixing heads or conveying troughs, and different end actuators can be quickly replaced according to specific operation requirements to achieve rapid changeover.

[0062] When in use, the speed-regulating motor 21 starts, and the power is transmitted to the reduction gearbox 23 through the coupling 22. After the reduction gearbox 23 reduces the speed and increases the torque, it drives the crank disc 31 to rotate at a constant speed. The eccentric adjustment shaft 32 on the crank disc 31 rotates with the crank disc, driving the connecting rod 33 to perform reciprocating push-pull motion. The connecting rod 33 further drives the rocker arm to perform continuous reciprocating swing around the swing shaft 42. The load connection end 5 at the end of the rocker arm swings synchronously, realizing operations such as shaking, flattening, sorting or conveying materials.

[0063] When the swing angle needs to be adjusted, loosen the locking nut of the eccentric adjustment shaft 32, move the eccentric adjustment shaft 32 to the target position along the radial groove of the crank plate 31, and then lock it again. The farther the eccentric adjustment shaft 32 is from the rotation center of the crank plate 31, the larger the swing angle of the rocker arm. The adjustment range is 0°–60°.

[0064] When stopping, simply turn off the speed-regulating motor 21 to stop the swinging motion. The overall structure is compact with no loose parts, and it can be directly installed on the equipment frame or table through the mounting holes at the bottom of the fixed base 1.

[0065] Example 1 of the limit stop.

[0066] The limiting module includes two limiting blocks 6, which are respectively connected to both sides of the bearing support 43.

[0067] In this technical solution, the swing angle of the rocker arm is limited by the limit block 6.

[0068] When the swing arm reaches its limit position, it abuts against the limit stop 6, limiting the swing angle from increasing further and preventing overtravel operation, thereby limiting the reciprocating swing angle range of the swing arm.

[0069] Example 2 of the limit stop.

[0070] The limiting module also includes two adjusting blocks 7. The adjusting blocks 7 include a mounting base 71. The mounting base 71 is connected to the side of the bearing support 43. Multiple guide shafts 72 are connected to the inner wall of the mounting base 71. A sliding plate 73 is slidably connected to the surface of the guide shafts 72. Both sides of the sliding plate 73 are connected to elastic connectors 74, and the end of the elastic connector 74 away from the sliding plate 73 is connected to the inner wall of the mounting base 71. A support mounting block 75 is connected to one side of the sliding plate 73, and a protective rubber pad 76 is connected to one side of the support mounting block 75.

[0071] In this technical solution, adjusting the stop block 7 avoids direct rigid collision between the swing arm and the limiting module, thereby reducing noise and preventing damage to the hinge point and transmission components.

[0072] A track 77 is connected to one side of the mounting base 71, and a sliding groove is provided on the side of the support mounting block 75 near the mounting base 71. The track 77 is slidably connected to the support mounting block 75 through the sliding groove.

[0073] In this technical solution, the movement trajectory of structures such as the support mounting block 75 and the sliding plate 73 is limited by the track bar 77.

[0074] The side of the support mounting block 75 and the side of the mounting base 71 are respectively connected to both ends of the dustproof cover cloth 78.

[0075] When the swing arm swings to its limit position, it first contacts the protective rubber pad 76. At this time, it drives the support mounting block 75 and the sliding plate 73 to move in the same direction. The elastic connector 74 is compressed and absorbs the impact energy, causing the swing arm to gradually decelerate to a stop, thus avoiding rigid collision.

[0076] It can eliminate or significantly reduce limit impact noise, improve the operating environment, and reduce the damage of impact loads to hinge points, bearings and transmission components, thus extending the service life of the mechanism.

[0077] Example 1 of a rocker arm.

[0078] The rocker arm includes a fixed rocker arm 41, which is a strip structure of fixed length.

[0079] Example 2 of the swing arm.

[0080] The rocker arm also includes an adjustable rocker arm 8, which includes a central gear 81. The central gear 81 is located inside the support housing 86. Adjusting racks 82 are meshed on both sides of the central gear 81. The end of the adjusting rack 82 away from the support housing 86 is connected to a mounting platform 83. The mounting platforms 83 on both sides are respectively connected to the swing shaft 42 and hinged to the connecting rod 33. Both ends of the central gear 81 are connected to adjustment knobs 85.

[0081] In this technical solution, the length of the adjustable swing arm 8 can be adjusted.

[0082] The adjusting rack 82 has a limiting port, and the inner wall of the supporting shell 86 is connected to a limiting strip 84. The limiting strip 84 is slidably connected to the adjusting rack 82 through the limiting port.

[0083] The two ends of the central gear 81 are rotatably connected to the two sides of the supporting housing 86.

[0084] Two symmetrically distributed sliding sleeves 87 are connected to the side of the mounting platform 83 near the support housing 86. The inner wall of the sliding sleeve 87 is slidably connected to the surface of the guide rail 88, and the guide rail 88 is connected to the side of the central gear 81. The cross-section of guide rail 88 is a T-shaped structure.

[0085] Locking components 9 are provided on both sides of the central gear 81. The locking components 9 include a locking plate 93, which is slidably connected to multiple connecting side plates 92. Both ends of the connecting side plates 92 are connected to fixing posts 91, and the sides of the fixing posts 91 are connected to the inner wall of the supporting shell 86. When one side of the engagement plate 93 is in contact with the central gear 81, engagement is achieved. Multiple elastic reset members 94 are connected to the other side of the engagement plate 93. One end of the elastic reset member 94 is connected to the connecting side plate 92. Multiple connecting strips 95 are connected to one side of the locking plate 93. One end of the connecting strip 95 is connected to one side of the locking plate 96. Both sides of the locking plate 96 are detachably connected to the locking bolts and nuts 97.

[0086] In this technical solution, the angle of the central gear 81 is locked by the locking component 9.

[0087] Both sides of the supporting shell 86 have through openings, and the connecting strip 95 is slidably connected to the supporting shell 86 through the through openings.

[0088] The adjustable swing arm 8 and locking assembly 9 allow for adjustment of the linear stroke and linear velocity of the end load by changing the arm length while keeping the swing angle constant; the same mechanism can be adapted to material trays or worktables of different sizes without the need to replace the swing arm.

[0089] In use, rotating the adjustment knob 85 drives the central gear 81 to rotate, which in turn drives the adjustment racks 82 on both sides to move towards or away from each other, which in turn drives the mounting platforms 83 on both sides to move towards or away from each other, thereby adjusting the distance between the mounting platforms 83.

[0090] After adjustment, the locking plates 96 on both sides are connected by locking bolts and nuts 97, so that the locking plates 96 on both sides are close to each other. When the locking plates 96 move, they drive the connecting strip 95 and the locking plate 93 to move in the same direction, so that the locking plate 93 is in contact with the side of the center gear 81, thereby locking the angle of the center gear 81 by using the locking plate 93.

[0091] When it is necessary to adjust the center gear 81, remove the locking bolt nut 97. At this time, under the action of the elastic reset member 94, the locking plate 93 and locking plate 96 and other structures return to their initial positions. At this time, the locking plate 93 moves away from the center gear 81, releasing the lock on the center gear 81.

[0092] The elastic connector 74 and the elastic reset component 94 are springs or other components with elastic reset function.
