Description

Technical Field

[0001] This utility model belongs to the technical field of lightweight processing equipment, specifically relating to a lightweight and compact dual-actuator common rail parallel motion mechanism. Background Technology

[0002] In current mechanical motion systems, the design and performance requirements for motion mechanisms are constantly increasing. Traditional single-acting sub-motion mechanisms have gradually revealed many limitations in some complex application scenarios. In similar equipment such as precision instruments and miniaturized production equipment with extremely demanding space utilization, single-acting sub-motion mechanisms cannot meet the needs of multiple components moving efficiently at the same time.

[0003] To address this, existing solutions offer multi-motion sub-mechanisms to meet the need for simultaneous and efficient movement of multiple components. However, some existing multi-motion sub-mechanisms often employ complex layouts and structural designs, which not only increase the overall weight and make the overall equipment bulky, but also make it difficult to flexibly expand and adjust the multi-motion sub-mechanisms, significantly limiting the expandability of the equipment. This is not conducive to the lightweight and compact design of the equipment, and gradually deviates from or becomes unsuitable for precision instruments and miniaturized production equipment with extremely demanding space utilization requirements.

[0004] In summary, existing multi-movement kinematic mechanisms still have problems in terms of structural complexity, weight, space utilization, and expandability. There is an urgent need for a dual-movement common-rail kinematic mechanism that is simple in structure, lightweight and compact, expandable, and has high space utilization. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a lightweight and compact dual-moving-subject common-rail parallel motion mechanism to solve the problems that still exist in the existing multi-moving-subject motion mechanisms in terms of structural complexity, weight, space utilization and expandability.

[0006] One aspect of this utility model provides a lightweight and compact dual-actuator common rail parallel motion mechanism, including a motor rail, a common rail motor group, a tool mounting assembly, and a connecting assembly. The tool mounting assembly is mounted on the common rail motor group through the connecting assembly, and the common rail motor group is movably connected to the motor rail.

[0007] The common rail motor assembly includes at least two common rail motors, each of which is connected to the connecting assembly;

[0008] The common rail motor assembly is used to control the position of the common rail motor on the motor rail, thereby controlling the working state of the connecting assembly; the connecting assembly is used to change its working state according to the position of the common rail motor on the motor rail, thereby controlling the working state of the tool mounting assembly; the tool mounting assembly is used to install machining tools and synchronously changes its working state when the working state of the connecting assembly changes.

[0009] It should be noted that the common rail motor set is connected to an external power supply device, which directly supplies power to each common rail motor in the set to control the position of each common rail motor on the motor track.

[0010] It should be noted that the working states of the connecting component and the tool mounting component include at least the direction of movement, the distance of movement, and the posture. In actual use, the working state of the connecting component will change in real time according to the position of each common rail motor on the motor guide rail, and then control the working state of the tool mounting component according to different working states. The specific structure of the connecting component and the working principle between the common rail motor group, the connecting component and the tool mounting component in actual use are described in detail below, and will not be repeated here.

[0011] It should be noted that, in actual use, the number of common rail motors and the specific structure of the connecting components in the common rail motor set can be expanded according to processing requirements. Specifically, workers can add common rail motors to the motor rail, add motor mounting shafts from the connecting components to the added common rail motors, add tool mounting shafts from the connecting components to the tool mounting components, and add connecting rods between the added tool mounting shafts and the added motor mounting shafts, in order to increase the number of tool mounting components and the adjustable range of the tilt of each tool mounting component.

[0012] In this solution, on the one hand, the position distribution of the common rail motor in the common rail motor group on the electric guide rail is controlled, thereby controlling the specific working state of the connecting component. Finally, the moving direction and distance of the tool mounting component are controlled by the specific working state of the connecting component. On the other hand, through the structure of the motor rail, common rail motor group, tool mounting component and connecting component, a lightweight and compact dual-actuator common rail parallel motion mechanism with simple structure, relatively light weight, high space utilization and strong expandability is provided.

[0013] Compared with existing technologies, this utility model has the following advantages:

[0014] 1. This utility model, through the cooperation of the motor track and the common rail motor group, can ensure the stable movement of the common rail motor in the common rail motor group on the motor track, thereby ensuring the stable movement of the connecting component that moves synchronously with the common rail motor and the stable movement of the tool mounting component installed on the connecting component, thus providing a guarantee for the stable machining of the machining tool on the tool mounting component. On the other hand, it realizes the coordinated movement of multiple movers in a limited space, enabling multiple common rail motors to move simultaneously on the motor track. While satisfying the simultaneous and efficient movement of multiple components, it improves the space utilization rate and avoids the waste of space, making it more suitable for precision instruments and miniaturized production equipment with extremely demanding space utilization.

[0015] 2. This utility model, through the cooperation of the common rail motor unit and the connecting component, can control the position of each common rail motor on the motor rail according to the actual processing requirements, thereby quickly adjusting the working state of the connecting component, and finally realizing the motion control of the tool mounting component. Furthermore, the operator can expand the common rail motor unit and the connecting component according to the actual processing requirements, so as to realize diversified working state control of the tool mounting component by controlling the position of each common rail motor on the motor rail, which has stronger expandability and practicality.

[0016] 3. This utility model forms a simple, lightweight and compact motion mechanism through the cooperation of motor rail, common rail motor group, tool mounting assembly and connecting assembly. The connection and cooperation between the components is simple. Compared with the complex layout and structural design of existing multi-movement mechanisms, this utility model does not have complicated intermediate transmission links and redundant structures, which greatly reduces the overall weight and makes the equipment more compact.

[0017] In one embodiment, the common rail motor includes a motor mover and a motor stator, and the common rail motor is movably connected to the motor rail via the motor mover;

[0018] The stator of the motor is used to generate a traveling wave magnetic field when the common rail motor is energized, and then provides the power for the motor mover to move on the motor track through the interaction between the traveling wave magnetic field and the permanent magnet magnetic field; the motor mover is used to provide the permanent magnet magnetic field and moves along the motor track under the interaction between the traveling wave magnetic field and the permanent magnet magnetic field.

[0019] It should be noted that the motor mover is a permanent magnet, and the motor stator has windings inside. When the common rail motor is energized, the current passes through the windings and generates a traveling wave magnetic field, which interacts with the permanent magnetic field of the permanent magnet, thereby driving the motor mover to move on the motor track.

[0020] In one embodiment, the common rail motor further includes a mounting housing, the motor stator is mounted inside the mounting housing, and the mounting housing is mounted on the motor mover.

[0021] It should be noted that, in actual use, the mounting housing is also equipped with a component for mounting the connecting assembly, which may be a bearing housing, to mount the motor mounting shaft in the connecting assembly described below, thereby connecting the common rail motor to the connecting assembly.

[0022] In one embodiment, the connecting assembly includes a motor mounting shaft, a tool mounting shaft, and a connecting rod. The motor mounting shaft is mounted on the common rail motor assembly, the tool mounting shaft is mounted on the tool mounting assembly, and the connecting rod connects the motor mounting shaft and the tool mounting shaft.

[0023] It should be noted that in actual use, workers can extend this utility model according to actual processing needs, such as adding a common rail motor to the motor rail, adding a motor mounting shaft from the connecting assembly to the added common rail motor, adding a tool mounting shaft from the connecting assembly to the tool mounting assembly, or adding a connecting rod between the added tool mounting shaft and the added motor mounting shaft.

[0024] In this solution, the motor mounting shaft can accurately transmit the rotational motion of the common rail motor to the connecting rod. On the one hand, the connecting rod can connect the motor mounting shaft and the tool mounting shaft, transmitting the motion of the common rail motor assembly to the tool mounting component. On the other hand, the connecting rod can ensure the structural strength and stability of the connecting component, enabling the common rail motor assembly to effectively resist external forces during operation, preventing structural deformation caused by vibration or impact, and ensuring the reliable operation of the entire motion mechanism.

[0025] By cooperating with the motor mounting shaft, the tool mounting shaft, and the connecting rod, complex motion trajectories can be controlled according to actual processing needs, thereby ensuring the positional accuracy of the processing tool during actual processing, improving the overall processing quality, and workers can directly extend this utility model by adding the motor mounting shaft, the tool mounting shaft, and the connecting rod.

[0026] In one embodiment, the common rail motor assembly includes a first common rail motor and a second common rail motor, and the connecting assembly includes a first motor mounting shaft and a second motor mounting shaft, wherein the first motor mounting shaft and the second motor mounting shaft are respectively mounted on the first common rail motor and the second common rail motor.

[0027] In one embodiment, the connecting assembly further includes a first connecting rod and a second connecting rod, the tool mounting shaft includes a central shaft, the central shaft is mounted in the middle of the tool mounting assembly, the first connecting rod connects the central shaft and the first motor mounting shaft, and the second connecting rod connects the central shaft and the second motor mounting shaft;

[0028] It should be noted that in actual use, the tool mounting assembly can be raised by keeping the first common rail motor stationary and moving the second common rail motor to the right. The same principle applies to lowering the tool mounting assembly, which will not be elaborated here. Alternatively, the tool mounting assembly can be moved synchronously by simultaneously controlling the first and second common rail motors to move synchronously.

[0029] In this solution, through the cooperation of the first common rail motor, the second common rail motor, the first motor mounting shaft, the second motor mounting shaft, the first connecting rod, the second connecting rod, and the central shaft, the first and second common rail motors can jointly control the height and horizontal movement distance of the tool mounting assembly. This allows for the synchronous control of the height and horizontal movement distance of the machining tool mounted on the tool mounting assembly according to actual machining requirements.

[0030] In one embodiment, the common rail motor unit includes a first common rail motor, a second common rail motor, and a third common rail motor. The connecting assembly includes a first motor mounting shaft, a second motor mounting shaft, and a third motor mounting shaft. The first motor mounting shaft, the second motor mounting shaft, and the third motor mounting shaft are respectively mounted on the first common rail motor, the second common rail motor, and the third common rail motor.

[0031] In one embodiment, the connecting assembly further includes a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod. The tool mounting shaft includes a first end shaft and a second end shaft, which are respectively mounted at both ends of the tool mounting assembly. The first connecting rod connects the first end shaft and the first motor mounting shaft. The second connecting rod connects the first end shaft and the second motor mounting shaft. The third connecting rod connects the second end shaft and the second motor mounting shaft. The fourth connecting rod connects the second end shaft and the third motor mounting shaft.

[0032] It should be noted that in actual use, the tool mounting assembly can be raised by keeping the No. 2 common rail motor stationary while simultaneously controlling the No. 1 and No. 3 common rail motors to move to the sides. The same principle applies to lowering the tool mounting assembly, which will not be elaborated here. Alternatively, the tool mounting assembly can be moved synchronously by simultaneously controlling the No. 1, No. 2, and No. 3 common rail motors to move synchronously. Furthermore, the left end of the tool mounting assembly can be raised by keeping the No. 2 and No. 3 common rail motors stationary while simultaneously controlling the No. 1 common rail motor to move to the left, allowing for adjustment of the tilt angle according to actual processing requirements.

[0033] In this solution, through the coordination of common rail motors No. 1, No. 2, and No. 3, the mounting shafts of motors No. 1, No. 2, and No. 3, as well as connecting rods No. 1, No. 2, No. 3, No. 4, end shafts No. 1, and No. 2, the common rail motors No. 3 and No. 1 can jointly control the height, horizontal movement distance, and tilt of the tool mounting assembly. This allows for the synchronous control of the height, horizontal movement distance, and tilt of the machining tool mounted on the tool mounting assembly according to actual machining requirements.

[0034] In one embodiment, the motor track includes a movable track and a fixed frame. The movable track is movably connected to the fixed frame, and the fixed frame has a movable groove for the movable track to move.

[0035] In one embodiment, a drive unit for moving the movable track is installed inside the fixed frame.

[0036] It should be noted that the driving component can be a push rod, telescopic rod, cylinder, or similar type of driving component.

[0037] In this solution, the movable track and the fixed frame work together to drive the common rail motor unit, the connecting component and the tool mounting component to move up and down synchronously. This allows the vertical machining range to be expanded when the machining range exceeds the maximum vertical machining range of the common rail motor unit, the connecting component and the tool mounting component.

The tool mounting assembly 3 is mounted on the common rail motor group 2 through the connecting assembly 4, and the common rail motor group 2 is movably connected to the motor rail 1.

[0053] It should be noted that the working states of the connecting component 4 and the tool mounting component 3 include at least the direction of movement, the distance of movement, and the posture. In actual use, the working state of the connecting component 4 will change in real time according to the position of each common rail motor on the motor guide rail, and thus control the working state of the tool mounting component 3 according to different working states. The specific structure of the connecting component 4 and the working principle between the common rail motor group 2, the connecting component 4 and the tool mounting component 3 in actual use are described in detail below, and will not be repeated here.

[0054] It should be noted that, in actual use, the number of common rail motors in the common rail motor unit 2 and the specific structure of the connecting component 4 can be expanded according to processing requirements.

[0062] It should be noted that the motor mover 5 is a permanent magnet, and the motor stator (not shown) has windings inside. When the common rail motor is energized, the current passes through the windings and generates a traveling wave magnetic field, which interacts with the permanent magnetic field of the permanent magnet, thereby driving the motor mover 5 to move on the motor track 1.

[0071] Please refer to Figure 1 It should be noted that in actual use, the tool mounting assembly 3 can be raised by controlling the first common rail motor 211 to stand still and controlling the second common rail motor 212 to move to the right. The same applies to lowering the tool mounting assembly 3, which will not be elaborated here. Alternatively, the tool mounting assembly 3 can be moved synchronously by controlling the first common rail motor 211 and the second common rail motor 212 to move synchronously.

[0072] Specifically, staff can directly control the first common rail motor 211 to remain stationary on the motor rail 1 through external power supply equipment, or they can fix the first common rail motor 211 on the motor rail 1 through other fasteners or mechanical parts, and control the other common rail motors in the common rail motor group 2 to remain stationary in the same way;

[0073] Taking the tool mounting assembly 3 as an example, when the first common rail motor 211 is stationary, the operator controls the second common rail motor 212 to move to the right.

The third connecting rod 428 connects the second end shaft 425 and the second motor mounting shaft 422. The fourth connecting rod 429 connects the second end shaft 425 and the third motor mounting shaft 423.

[0077] Please refer to Figure 2 It should be noted that in actual use, the tool mounting assembly 3 can be raised by keeping the No. 2 common rail motor 222 stationary while simultaneously controlling the No. 1 common rail motor 221 and the No. 3 common rail motor 223 to move to both sides. The same applies to lowering the tool mounting assembly 3, which will not be elaborated here. The tool mounting assembly 3 can also be moved synchronously by simultaneously controlling the No. 1 common rail motor 221, the No. 2 common rail motor 222, and the No. 3 common rail motor 223 to move synchronously. Alternatively, the tool mounting assembly 3 can be raised by keeping the No. 2 common rail motor 222 and the No. 3 common rail motor 223 stationary while simultaneously controlling the No. 1 common rail motor 221 to move to the left, so that the tilt can be adjusted according to the actual processing requirements.

[0078] Specifically, staff can directly control the second common rail motor 212 or the third common rail motor to be stationary on the motor rail 1 through external power supply equipment, or they can fix the second common rail motor 212 or the third common rail motor on the motor rail 1 through other fasteners or mechanical parts, and control the other common rail motors in the common rail motor group 2 to be stationary in the same way;

[0079] Taking the lifting of the tool mounting assembly 3 as an example, when the second common rail motor 222 is stationary, the operator controls the first common rail motor 221 to move to the left, and simultaneously controls the third common rail motor 223 to move to the right. During this process, the first connecting rod 426, the second connecting rod 427, the third connecting rod 428, and the fourth connecting rod 429 gradually tend to be horizontal. The first end shaft 424 on the tool mounting assembly 3 is gradually lifted under the traction of the first connecting rod 426 and the second connecting rod 427. Simultaneously, the second end shaft 425 on the tool mounting assembly 3 is gradually lifted under the traction of the third connecting rod 428 and the fourth connecting rod 429, thus jointly achieving the lifting of the tool mounting assembly 3.

[0080] Taking the lifting of the left end of the tool mounting assembly 3 as an example, when the No. 2 common rail motor 222 and the No. 3 common rail motor 223 are stationary, the operator controls the No. 1 common rail motor 221 to move to the left. Under the traction of the No. 1 end shaft 424 on the tool mounting assembly 3, it is gradually lifted, thereby lifting the left end of the tool mounting assembly 3.

[0081] In actual use, the machining tool located on the side of the tool mounting assembly 3 can be used for machining by changing the tilt angle of the tool mounting assembly 3 according to the actual machining needs.

[0082] In this embodiment, through the cooperation of common rail motor 221, common rail motor 222, common rail motor 223, motor mounting shaft 421, motor mounting shaft 422, motor mounting shaft 423, connecting rod 426, connecting rod 427, connecting rod 428, connecting rod 429, end shaft 424, and end shaft 425, the common rail motors 221, 222, and 323 can jointly control the height, horizontal movement distance, and tilt of the tool mounting assembly 3. This allows for the synchronous control of the height, horizontal movement distance, and tilt of the machining tool mounted on the tool mounting assembly 3 according to actual machining requirements.

[0083] In one embodiment, the motor track 1 includes a movable track 11 and a fixed frame 12. The movable track is movably connected to the fixed frame 12, and the fixed frame 12 has a movable groove 13 for the movable track to move.

[0084] In one embodiment, the mounting frame 12 is equipped with a drive element (not shown) for driving the movement of the moving track.

[0085] It should be noted that the driving component can be a push rod, telescopic rod, cylinder, or similar type of driving component.

[0086] In this embodiment, the movable track 11 and the fixed frame 12 work together to drive the common rail motor 2, the connecting component 4 and the tool mounting component 3 to move up and down synchronously. This allows the vertical processing range to be expanded when the processing range exceeds the maximum vertical processing range of the common rail motor 2, the connecting component 4 and the tool mounting component 3.

[0087] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
