[0002] At present, in the field of modern industrial automation, especially in industries with high precision requirements such as CNC machine tools, automobile manufacturing, mold processing, aerospace and military industry, the precise synchronous movement of pneumatic or hydraulic systems is the key to achieving efficient and stable production processes. The synchronous movement of pneumatic or hydraulic systems usually relies on the coordinated movement of two or more active ends to ensure the precise alignment of objects during processing or assembly.

[0003] However, in order to achieve synchronous movement of the two moving ends, the existing technology usually adopts an electrical control method, using sensors to monitor the position of each moving end in real time, and then adjusting the motion parameters through a controller to achieve synchronization. However, this electrical control method is limited in certain special environments. For example, in the presence of electromagnetic interference, flammable and explosive gases, high-voltage electric fields, etc., the use of electrical components may bring safety hazards or the risk of control failure.

[0054] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0055] like Figures 1 to 4 As shown, the first embodiment of the present invention provides a motion device, which includes a first movable structure 10 and a second movable structure 20, and any one of the first movable end 11 of the first movable structure 10 and the second movable end 21 of the second movable structure 20 is movably arranged in a direction close to or away from the other. The motion device also includes a gear 30, a first rack 40 and a second rack 50, and the first rack 40 and the second rack 50 are both meshed with the gear 30, and the first rack 40 and the second rack 50 are both extended along the extension direction from the first movable end 11 to the second movable end 21, and the tooth portion of the first rack 40 is used to be arranged opposite to the tooth portion of the second rack 50. Among them, the first movable end 11 is connected to the first rack 40, and the second movable end 21 is connected to the second rack 50. The first movable structure 10 is a pneumatic cylinder or a hydraulic cylinder, and the second movable structure 20 is a pneumatic cylinder or a hydraulic cylinder.

[0056] The motion device provided by the first embodiment of the present invention adopts a design in which the gear 30 is meshed with the first rack 40 and the second rack 50, so that even without the intervention of sensors or electrical components, the first movable end 11 of the first movable structure 10 (pneumatic cylinder or hydraulic cylinder) and the second movable end 21 of the second movable structure 20 (pneumatic cylinder or hydraulic cylinder) can maintain precise synchronous motion. This mechanical synchronization method overcomes the limitations of electrical control in certain special environments, while avoiding the disadvantage that the synchronization accuracy of the mechanical synchronization mechanism decreases after long-term operation, ensuring the motion accuracy and equipment safety in complex or special environments. Such a setting is applicable to various types of pneumatic cylinders or hydraulic cylinders, whether single-acting cylinders or double-acting cylinders, and can adapt to different strokes and load requirements by adjusting the meshing relationship between the gear 30 and the first rack 40 and the second rack 50. This flexibility allows the present solution to be widely used in different industrial fields. Furthermore, the teeth of the first rack 40 and the teeth of the second rack 50 are arranged opposite to each other, and the precise meshing of the gear 30 ensures stability and reliability even under high speed, heavy load or complex working conditions, reduces vibration and displacement errors during movement, and improves the overall working efficiency and finished product quality of the equipment. Therefore, the motion device provided in this embodiment can solve the technical problem that the two movable ends of the motion device in the prior art are difficult to accurately perform synchronous movement.

[0057] Specifically, the first movable structure 10 and the second movable structure 20 have the same cylinder diameter, the same stroke and the same load, but the first movable end 11 and the second movable end 21 move in opposite directions.

[0058] Specifically, one of the first movable end 11 and the second movable end 21 is connected to one of the first rack 40 and the second rack 50, and the motion device further includes a connecting structure 60, on which a mounting groove 61 is provided, and one of the first movable end 11 and the second movable end 21 is inserted into the mounting groove 61, and one of the first rack 40 and the second rack 50 is located on one side of the connecting structure 60 and connected to the connecting structure 60. With such a structural setting, the movable end is inserted and fixed by using the mounting groove 61 on the connecting structure 60, which can effectively enhance the structural stability between the movable end and the rack, reduce displacement and deformation during the movement process, and thus improve the accuracy and reliability of the motion device. The design of the mounting groove 61 allows the first movable end 11 or the second movable end 21 to be easily inserted and fixed on the connecting structure 60, simplifies the installation steps, and reduces the need for professional tools. At the same time, this modular connection method facilitates maintenance or replacement of components, reduces equipment downtime, and improves production efficiency.

[0059] It should be noted that the first movable end 11 is connected to the first rack 40, the first movable end 11 is inserted into the mounting groove 61, the first rack 40 is located on one side of the connecting structure 60 and is connected to the connecting structure 60; or, the second movable end 21 is connected to the second rack 50, the second movable end 21 is inserted into the mounting groove 61, the second rack 50 is located on one side of the connecting structure 60 and is connected to the connecting structure 60.

[0060] Specifically, the connection structure 60 includes a first connection member 62 and a second connection member 63, a mounting groove 61 is provided on the first connection member 62, and one of the first rack 40 and the second rack 50 is connected to the second connection member 63. The first connection member 62 and the second connection member 63 are both extended along the extension direction from the first movable end 11 to the first rack 40, one of the first movable end 11 and the second movable end 21 is connected to one end of the first connection member 62, and the other end of the first connection member 62 is connected to the second connection member 63. With such a structural setting, this split connection design improves the connection flexibility between the components of the motion device, so that the assembly is adapted to pneumatic cylinders or hydraulic cylinders of different sizes, and enhances the versatility and scalability of the motion device. The first connecting member 62 and the second connecting member 63 are ensured to extend along the extension direction from the first movable end 11 to the first rack 40, which optimizes the force transmission path during the movement, so that the air pressure or hydraulic force can be smoothly transmitted to the gear 30 through the rack, and then transmitted to the rack and the air / hydraulic cylinder on the other side through the gear 30. This design improves the efficiency of force transmission and reduces energy loss. By accurately controlling the connection between the first connecting member 62 and the second connecting member 63, the vibration of the air cylinder or hydraulic cylinder during the movement can be effectively reduced, and the close meshing between the rack and the gear 30 can be maintained, thereby improving the stability and accuracy of the entire motion device and ensuring that the two movable ends can achieve high-precision synchronous movement.

[0061] Specifically, the first connecting member 62 includes a first connecting plate 621 , a second connecting plate 622 and a third connecting plate 623 which are connected in sequence. The first connecting plate 621 and the third connecting plate 623 are arranged opposite to each other and form a mounting groove 61 .

[0062] Specifically, the connection structure 60 further includes a third connection member 64 , at least a portion of the third connection member 64 is inserted into the mounting groove 61 , and the second connection member 63 is connected to the first connection member 62 via the third connection member 64 .

[0063] Specifically, the second connecting member 63 is connected to one of the first rack 40 and the second rack 50 on a side close to the connecting structure 60; or, the second connecting member 63 is connected to one of the first rack 40 and the second rack 50 on a side away from the connecting structure 60. With such a structural setting, the connection position of the second connecting member 63 and the first rack 40 or the second rack 50 is flexibly adjustable, which increases the adaptability of the motion device in different application scenarios, makes the connection mode between the rack and the pneumatic cylinder or the hydraulic cylinder more diversified, and meets the requirements of different mechanical layouts.

[0064] In this embodiment, there are two connecting structures 60, one of the two connecting structures 60 is connected to the first rack 40, and the other is connected to the second rack 50. The second connecting member 63 of one of the two connecting structures 60 is connected to a side of the first rack 40 away from one of the two connecting structures 60. The second connecting member 63 of the other of the two connecting structures 60 is connected to a side of the second rack 50 close to the other of the two connecting structures 60.

[0065] Specifically, the second connecting member 63 is movably arranged in a direction close to or away from the first connecting member 62. With such a structural arrangement, the second connecting member 63 is movably arranged in a direction close to or away from the first connecting member 62. This dynamic adjustment capability enables the motion device to adapt to different working strokes and ranges of activity. Even if the length of the rack is not enough, it can be compensated by the movement of the second connecting member 63 to maintain the synchronous movement of the pneumatic cylinder or the hydraulic cylinder.

[0066] In this embodiment, the motion device further comprises a mounting member 70, which is arranged between the first movable structure 10 and the second movable structure 20. The mounting member 70 is provided with a mounting groove 71, which is extended along the extending direction from the first movable end 11 to the second movable end 21. The gear 30, at least part of the first rack 40 and at least part of the second rack 50 are all arranged in the mounting groove 71. The mounting groove 71 has a first groove wall 711 and a second groove wall 712 which are arranged oppositely and spaced apart. At least part of the first rack 40 is arranged in contact with the first groove wall 711, and at least part of the second rack 50 is arranged in contact with the second groove wall 712. With such a structural arrangement, the mounting groove 71 design of the mounting member 70 effectively integrates the layout of the gear 30, the first rack 40 and the second rack 50, which not only saves the floor space of the overall motion device, but also provides good protection for these key motion components, avoids direct damage to them by external environmental factors (such as dust and collision), and prolongs the service life of the components. In addition, the first groove wall 711 and the second groove wall 712 in the assembly groove 71, by being arranged in contact with the first rack 40 and the second rack 50, limit the lateral displacement of the rack during movement, improve the meshing accuracy between the rack and the gear 30, and thus ensure the stability and synchronization of the moving device during operation.

[0067] Specifically, the mounting member 70 includes a first mounting plate 72, a second mounting plate 73 and a third mounting plate 74 connected in sequence, the first mounting plate 72 and the third mounting plate 74 are arranged opposite to each other, and the first mounting plate 72, the second mounting plate 73 and the third mounting plate 74 surround the assembly groove 71; the first mounting plate 72 forms a first groove wall 711 on one side close to the third mounting plate 74, and the third mounting plate 74 forms a second groove wall 712 on one side close to the first mounting plate 72. Such a structural arrangement not only increases the structural stability of the mounting member 70, but also ensures the shape and dimensional accuracy of the assembly groove 71, providing a stable working environment for the rack and gear 30.

[0068] Specifically, a first guide is provided on the first rack 40, and a second guide adapted to guide the first guide is provided on the first groove wall 711. Both the first guide and the second guide are extended along the extending direction from the first movable end 11 to the second movable end 21. In this way, the guiding adaptation of the first guide and the second guide ensures the linear motion of the first rack 40 in the assembly groove 71, reduces the meshing error caused by the rack offset, and improves the motion accuracy. In addition, the design of the guide reduces the direct contact between the rack and the mounting member 70, reduces the wear during the motion process, thereby extending the service life of the first rack 40 and the mounting member 70 and reducing the maintenance cost.

[0069] Specifically, a third guide is provided on the second rack 50, and a fourth guide adapted to guide the third guide is provided on the second groove wall 712, and both the third guide and the fourth guide are extended along the extending direction from the first movable end 11 to the second movable end 21. In this way, accurate guidance of the second rack 50 is achieved, ensuring the linear motion of the second rack 50 on the second groove wall 712, forming symmetry with the motion of the first rack 40, and enhancing the synchronization performance of the entire motion device.

[0070] Specifically, the first guide member and the third guide member are both guide protrusions, and the second guide member and the fourth guide member are both guide grooves.

[0071] Specifically, the gear 30 is detachably arranged in the assembly groove 71, and one of the first mounting plate 72 and the second mounting plate 73 is movably arranged in a direction close to or away from the other. With such a structural arrangement, the detachable design of the gear 30 makes it easy to replace the worn or damaged gear 30 during maintenance and upgrading without disassembling the entire motion device, greatly reducing the maintenance cost and time. At the same time, the movability of one of the first mounting plate 72 and the second mounting plate 73 provides the possibility of fine-tuning the position of the gear 30, which helps to maintain the precise meshing between the gear and the rack after long-term operation, and improves the accuracy and stability of the movement. Allowing the first mounting plate 72 or the second mounting plate 73 to move in a direction close to or away from each other under the guidance of the assembly groove 71 increases the flexibility of the structure, and can fine-tune the space in the assembly groove 71 without changing the layout of the main components to accommodate gears 30 or racks of different sizes, while maintaining the structural stability and mechanical strength of the entire motion device.

[0072] In this embodiment, a lubrication channel is provided on the mounting member 70, and the lubrication channel is connected to the lubrication medium source and is connected to the assembly groove 71. In this way, the lubrication channel provided on the mounting member 70 can ensure that key moving parts such as the gear 30, the first rack 40 and the second rack 50 are fully lubricated. This design not only improves the lubrication efficiency of the moving parts, reduces friction and wear during the movement process, but also enhances the protection of the parts, extends the service life of the moving device, and reduces maintenance costs. By connecting with the lubrication medium source, automatic lubrication can be achieved, reducing the need for manual lubrication, avoiding the risk of operators directly contacting the moving parts, and improving operational safety. At the same time, the automatic lubrication system helps to maintain the stability and reliability of the moving device under various working conditions.

[0073] Specifically, the motion device further includes a control member and a distance detection member connected to each other. The distance detection member is arranged on the mounting member 70. The detection end of the distance detection member is located on the side of the mounting member 70 away from the gear 30 and is used to detect the distance between the first movable end 11 and the second movable end 21. The first movable structure 10 and the second movable structure 20 are both connected to the control member. The control member is used to control the first movable structure 10 and the second movable structure 20 to be in a running state in which the first movable end 11 and the second movable end 21 are both moved or in a static state in which the first movable end 11 and the second movable end 21 are both static according to the detection result of the distance detection member. With such a structural setting, the distance detection member can be used to monitor the change of the distance between the first movable end 11 and the second movable end 21 in real time. This real-time monitoring capability provides key feedback information for the control member, so that the control member can accurately control the motion state of the first movable structure 10 and the second movable structure 20 according to the real-time detection result, thereby improving the synchronization accuracy and control efficiency of the motion device. This provides a safety mechanism for the motion device. When it is detected that the distance between the moving ends exceeds the preset threshold, the control component can immediately stop the movement of the pneumatic cylinder or hydraulic cylinder, preventing mechanical damage or operational accidents that may be caused by synchronous movement disorders, and ensuring the safety of equipment and operators.

[0074] Specifically, when the distance detecting member detects that the distance between the first movable end 11 and the second movable end 21 is less than a preset threshold value, the first movable structure 10 is placed in a first stationary state in which the first movable end 11 is stationary, and the second movable structure 20 is placed in a second stationary state in which the second movable end 21 is stationary; when the distance detecting member detects that the distance between the first movable end 11 and the second movable end 21 is greater than or equal to the preset threshold value, the first movable structure 10 is placed in a first operating state in which the first movable end 11 is moved, and the second movable structure 20 is placed in a second operating state in which the second movable end 21 is moved.

[0075] Specifically, the gear 30 is a helical gear, and the first rack 40 and the second rack 50 are both helical racks. In this way, the meshing between the helical gear and the helical rack can effectively improve the efficiency and stability of power transmission. Compared with spur gears, helical gears can reduce noise and vibration during the meshing process, making the movement smoother, and are particularly suitable for occasions requiring high-precision synchronous movement. When the helical gear structure is working, the tooth surface contact is progressive, which can avoid the instantaneous impact of spur gears, extend the service life of the rack and gear 30, reduce maintenance costs, and also improve the reliability and durability of the entire motion device.

[0076] Specifically, the motion device further includes a visual detection member and a control member, wherein the visual detection member is arranged on one side of the gear 30, and the detection end of the visual detection member is arranged toward the gear 30 and is used to detect the meshing condition between the first rack 40 and the gear 30 and the meshing condition between the second rack 50 and the gear 30. The first movable structure 10, the second movable structure 20 and the visual detection member are all connected to the control member, so as to control the first movable structure 10 and the second movable structure 20 to be in a running state in which both the first movable end 11 and the second movable end 21 are moved or in a static state in which both the first movable end 11 and the second movable end 21 are static according to the detection result of the visual detection member. With such a structural setting, key information support is provided for the intelligent control of the motion device, and the accuracy of synchronous motion is ensured. When the visual detection member detects an abnormal meshing condition between the rack and the gear 30 (such as rack offset, gear wear, etc.), the control member can respond quickly according to the detection result, adjust the motion state of the first movable structure 10 and the second movable structure 20, so that it is in a static state, prevent further mechanical failure and equipment damage, and improve the operation safety and stability of the equipment. The monitoring data of the visual inspection parts can be used for intelligent maintenance of the equipment. By analyzing the changing trend of the meshing condition, the potential failure of the gear 30 and the rack can be predicted, and maintenance or replacement can be performed in advance, thus avoiding unplanned equipment downtime, reducing maintenance costs, and improving the operating efficiency of the equipment.

[0077] Specifically, the detection end of the visual inspection part is equipped with a high-resolution industrial camera and a corresponding lighting system, such as an LED light source, to ensure that the details between the rack and the gear 30 are clearly captured. The detection end is set at a position that can fully cover the gear 30 and the meshing rack area with it, and the angle must ensure that the light can be vertically irradiated on the meshing surface of the rack and the gear 30 to reduce the impact of shadows and uneven brightness on the image quality. According to the running speed of the motion device, the capture frequency of the industrial camera is set to ensure that each meshing of the rack and the gear 30 can be recorded and analyzed. Image processing techniques such as gain control, image sharpening, background subtraction, etc. are used to ensure that the captured image is clear and has high contrast, which is convenient for subsequent analysis. Through image processing algorithms, such as feature point detection and image alignment technology, it is ensured that each captured image can be accurately aligned and preprocessed, remove noise in the image, and improve the analysis accuracy. According to the acquired image, by identifying the relative position change between the edge of the rack and the tooth surface of the gear 30, it is determined whether the rack is offset to ensure the accuracy of the synchronous motion. According to the acquired image, the profile change of the tooth surface of the gear 30 is analyzed, the degree of wear is identified, and the gear damage that may affect the performance of the synchronous motion is warned. When a serious meshing anomaly is detected, such as a serious rack offset or a serious wear of the gear 30, the control unit should immediately stop the movement of the pneumatic cylinder or hydraulic cylinder to avoid further equipment damage. The images and analysis results captured by the visual inspection unit are recorded for a long time, and the potential maintenance needs of the equipment can be identified through data analysis techniques such as statistical analysis and trend prediction to achieve predictive maintenance.

[0078] A second embodiment of the present invention provides a machine tool, which includes the motion device provided in the first embodiment.

[0079] The machine tool provided by the second embodiment of the present invention adopts a design in which the gear 30 is meshed with the first rack 40 and the second rack 50, so that even without the intervention of sensors or electrical components, the first movable end 11 of the first movable structure 10 (pneumatic cylinder or hydraulic cylinder) and the second movable end 21 of the second movable structure 20 (pneumatic cylinder or hydraulic cylinder) can maintain precise synchronous motion. This mechanical synchronization method overcomes the limitations of electrical control in certain special environments, while avoiding the disadvantage that the synchronization accuracy of the mechanical synchronization mechanism decreases after long-term operation, ensuring the motion accuracy and equipment safety in complex or special environments. Such a setting is applicable to various types of pneumatic cylinders or hydraulic cylinders, whether single-acting cylinders or double-acting cylinders, and can adapt to different strokes and load requirements by adjusting the meshing relationship between the gear 30 and the first rack 40 and the second rack 50. This flexibility allows the present solution to be widely used in different industrial fields. Furthermore, the teeth of the first rack 40 and the teeth of the second rack 50 are arranged opposite to each other, and the precise meshing of the gear 30 ensures stability and reliability even under high speed, heavy load or complex working conditions, reduces vibration and displacement errors during movement, and improves the overall equipment work efficiency and finished product quality. Therefore, the machine tool provided by this embodiment can solve the technical problem that the two movable ends of the motion device in the prior art are difficult to accurately perform synchronous movement.

[0080] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: in situations where electrical components such as sensors are not supported, two gas / hydraulic cylinders with the same cylinder diameter, the same stroke and the same load, but in opposite directions can achieve synchronous movement, such as a double door driving cylinder.
