Description

Technical Field

[0001] The present invention belongs to the technical field of composite product forming equipment, and particularly relates to a digital full-process monitoring tailstock system. Background Art

[0002] In composite forming processes such as fiber winding or thermosetting filament placement, in order to ensure the stability of the workpiece during processing, a clamping device is usually set to clamp and position the mold or mandrel. The traditional method mostly uses a hydraulic cylinder to provide axial thrust to achieve the clamping function.

[0003] However, the hydraulic drive method has the following problems:

[0004] Poor thrust control accuracy: The output thrust of the hydraulic cylinder depends on the pressure and flow rate of the hydraulic oil, and these parameters are easily affected by temperature fluctuations, oil aging, system pressure drop, etc., resulting in unstable actual thrust output and difficulty in meeting the requirements of modern high-precision processing.

[0005] Lack of thrust feedback mechanism: Traditional hydraulic systems generally do not have real-time thrust detection and feedback means, and cannot achieve closed-loop control, resulting in the clamping force not being dynamically adjusted according to the working conditions and affecting process consistency.

[0006] High leakage risk and maintenance cost: The hydraulic system is prone to leakage after long-term operation, especially under high-temperature and high-load working conditions, and the aging of oil pipes, joints and seals leads to frequent maintenance. In addition, once the hydraulic oil leaks, it is very easy to contaminate carbon fiber or other composite materials, resulting in the scrapping of products.

[0007] Large volume and low energy efficiency: Components such as hydraulic stations, oil tanks, and pipelines have complex structures, occupy a large amount of space, the overall energy efficiency of the system is low, and the operating cost is high.

[0008] Therefore, in view of the above technical problems, it is necessary to provide a digital full-process monitoring tailstock system.

[0009] The information disclosed in this background art section is only for enhancing the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Invention

[0010] The purpose of the present invention is to provide a digital full-process monitoring tailstock system, which can solve the problems in the above background art.

[0011] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the present invention is as follows:

[0012] A digital full-process monitoring tailstock system, comprising: a tailstock box, a tailstock mechanism, a driving mechanism, and a tension and compression sensor;

[0013] A control box is installed on the tailstock box, and a closed-loop control system is installed inside the control box;

[0019] A fixing ring is fixedly connected to the side wall of the handwheel located inside the fixed seat, and a sliding groove matching the fixing ring is arranged inside the fixed seat.

[0020] In one or more embodiments of the present invention, a rotating ring is rotatably connected to the lower end of the fixing ring. The rotating ring is arranged inside the sliding groove. The minimum diameter of the rotating ring is larger than the minimum diameter of the fixing ring. The rotating ring is used to contact the pressure ring, and thus the pressure ring can be extruded to move inside the sliding groove, and at the same time, it will not affect the rotation of the handwheel and the fixing ring.

[0021] In one or more embodiments of the present invention, a pressure ring and a spring are arranged inside the sliding groove. Both the pressure ring and the spring surround the handwheel. The pressure ring is arranged between the rotating ring and the spring. The rotating ring extrudes the spring through the pressure ring, and the spring is used to generate a force on the pressure ring, the rotating ring and the fixing ring, so that the polygonal column is separated from the engagement groove in the natural state.

[0022] In one or more embodiments of the present invention, a linkage groove is provided in the fixed seat. One end of the handwheel located in the linkage groove is connected with a polygonal column. One end of the worm is arranged in the linkage groove, and a clamping groove matching the polygonal column is provided at the end of the worm.

Detailed implementation mode

[0042] In order to enable the personnel in the technical field to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0043] As Figures 1 to 9 shown, the digital full - process monitoring tailstock system in an embodiment of the present invention includes a tailstock box 1, a tailstock mechanism 2, a driving mechanism 3, and a tensile and compressive sensor 4.

[0044] Among them, the tailstock box 1 adopts a two - stage structure design. By reducing the casting size, the influence of thermal stress during the casting process is reduced, and the influence of shrinkage deformation on the accuracy is avoided, so as to improve the installation convenience, accuracy adjustment ability, and long - term stability of the tailstock box 1.

[0045] In addition, a control box is installed on the tailstock box 1, and a closed - loop control system is installed in the control box. The closed - loop control system is used to read the signal of the tensile and compressive sensor 4 and adjust the servo motor 304 instruction in real time to achieve constant force output or progressive loading.

[0046] As Figures 1 to 9 shown, the tailstock mechanism 2 is fixedly connected to the tailstock box 1. The tailstock mechanism 2, as the tailstock component of the fiber winding machine, is mainly used for lifting.

[0047] Among them, the tailstock mechanism 2 includes a tailstock seat 201, and a telescopic tailstock piece 202 is slidably arranged in the tailstock seat 201. The telescopic tailstock piece 202 can be used to lift the winding shaft for fiber winding.

[0048] In addition, a locking device 203 is installed on the side wall of the tail top seat 201. The locking device 203 corresponds to the telescopic tail top member 202, and the locking device 203 is used to lock the telescopic tail top member 202.

[0049] As Figures 1 to 9 shown, the driving mechanism 3 is installed on the tail top seat 201. The driving mechanism 3 is used to control the lifting of the telescopic tail top member 202, and has significant advantages in terms of accuracy, response speed and stability compared with the traditional hydraulic control method.

[0050] Among them, the driving mechanism 3 includes a worm reducer 301. A worm 302 and a linkage gear 303 are rotatably connected inside the worm reducer 301, and the worm 302 meshes with the linkage gear 303. When the worm 302 rotates, the worm 302 can drive the linkage gear 303 to rotate to achieve transmission.

[0051] As Figures 1 to 9 shown, a fixed seat 3011 is fixedly connected to the worm reducer 301, and a handwheel 3012 is slidably arranged on the fixed seat 3011. Through the setting of the handwheel 3012, it is convenient for the staff to manually adjust the screw 305, and then the telescopic tail top member 202 can be manually lifted.

[0052] Among them, a fixed ring 3013 is fixedly connected to the side wall of the handwheel 3012 located inside the fixed seat 3011, and a sliding groove matching the fixed ring 3013 is arranged inside the fixed seat 3011. A rotating ring 3014 is rotatably connected to the lower end of the fixed ring 3013. The rotating ring 3014 is arranged in the sliding groove, and the minimum diameter of the rotating ring 3014 is greater than the minimum diameter of the fixed ring 3013. The rotating ring 3014 is used to contact the pressure ring 3015, and then the pressure ring 3015 can be extruded to move in the sliding groove, and at the same time, it will not affect the rotation of the handwheel 3012 and the fixed ring 3013, that is, when the rotating ring 3014 contacts the pressure ring 3015, the rotating ring 3014 and the fixed ring 3013 can rotate relative to each other.

[0053] In addition, a pressure ring 3015 and a spring 3016 are arranged in the sliding groove. The pressure ring 3015 and the spring 3016 both surround the handwheel 3012, and the pressure ring 3015 is arranged between the rotating ring 3014 and the spring 3016. The rotating ring 3014 squeezes the spring 3016 through the pressure ring 3015, and the spring 3016 is used to exert a force on the pressure ring 3015, the rotating ring 3014 and the fixed ring 3013, so that the polygonal column 3017 is separated from the engagement groove in the natural state.

[0054] Specifically, a linkage groove is provided inside the fixed seat 3011. One end of the handwheel 3012 located inside the linkage groove is connected with a polygonal column 3017. One end of the worm 302 is arranged inside the linkage groove, and a clamping groove matching with the polygonal column 3017 is provided at the end of the worm 302. When the polygonal column 3017 is inserted into the clamping groove, rotating the handwheel 3012 can drive the worm 302 to rotate, and then the telescopic tail top piece 202 can be manually adjusted.

[0055] When manual adjustment of the telescopic tail top piece 202 is required, press the handwheel 3012 to insert the polygonal column 3017 on the handwheel 3012 into the clamping groove. At this time, rotating the handwheel 3012 can drive the worm 302 to rotate, and then drive the linkage gear 303 and the screw 305 to rotate to realize the jacking of the telescopic tail top piece 202. When manual adjustment is not required, release the handwheel 3012, and the handwheel 3012 rises under the combined action of the spring 3016, the pressure ring 3015, the rotating ring 3014 and the fixed ring 3013, so that the polygonal column 3017 disengages from the clamping groove.

[0056] As Figures 1 to 9 shown, a servo motor 304 is installed at the lower bottom of the worm reducer 301. The servo motor 304 is electrically connected to the control box, the output end of the servo motor 304 is connected to the worm 302, and a screw 305 is rotatably connected to the worm reducer 301. The screw 305 is threadedly connected to the linkage gear 303. When the servo motor 304 operates, the servo motor 304 drives the worm 302 to rotate, and the worm 302 drives the linkage gear 303 to rotate. Since the screw 305 is threadedly connected to the linkage gear 303, the screw 305 can move. In this application, the output torque of the servo motor 304 is converted into thrust output through a high-precision worm gear pair, which not only improves the load capacity but also ensures the smoothness of the tightening process.

[0057] As Figures 1 to 9 shown, one end of the screw 305 located inside the tail top seat 201 is connected with a buffer mechanism 306, which further improves the safety and reliability of the system.

[0058] Among them, the buffer mechanism 306 includes a connecting plate 3061. The connecting plate 3061 is fixedly connected to the screw 305. The center of the side of the connecting plate 3061 away from the screw 305 is connected with a guiding rod 3062, and the guiding rod 3062 is used for limiting the buffer disc spring group 3063.

[0059] In addition, a buffer disc spring group 3063 is arranged outside the guiding rod 3062. The buffer disc spring group 3063 can provide an additional force storage function, ensure a continuous and stable tightening effect, absorb part of the energy during sudden impact, reduce the impact load on the screw 305, and improve the safety and service life of the equipment.

[0060] Specifically, a buffer seat 3064 is provided on one side of the connecting plate 3061 , and the buffer seat 3064 is used to install the tension and compression sensor 4 and limit multiple buffer disc spring groups 3063 .

[0061] In addition, a plurality of fastening rods 3065 are connected between the connecting plate 3061 and the buffer seat 3064, and the buffer disc spring group 3063 is arranged between the connecting plate 3061 and the buffer seat 3064, so that the connecting plate 3061, the buffer disc spring group 3063 and the buffer seat 3064 are connected as a whole.

[0062] Furthermore, a buffer cavity 3066 and a through hole are provided in the buffer seat 3064, a buffer plate 3067 is provided in the buffer cavity 3066, and a buffer spring 3068 is provided between the buffer plate 3067 and the side wall of the buffer seat 3064. When the screw rod 305 is inserted into the buffer cavity 3066 through the through hole, the screw rod 305 contacts the buffer plate 3067, and the buffer plate 3067 can squeeze the buffer spring 3068 to provide a reverse buffer force, further reducing the impact load on the screw rod 305, and improving the safety and service life of the equipment.

[0063] First, the buffer mechanism 306 has the function of storing thrust to avoid force attenuation caused by the stop of the servo motor 304 or the slight displacement of the system. Secondly, it absorbs sudden impacts, reduces the damage to the tailstock box 1, and improves the durability of the equipment. Finally, it can also reduce the load of the servo motor 304, reduce the power consumption and wear caused by frequent start and stop, and further extend the life of the equipment.

[0064] like Figures 1 to 9 As shown, a protective member 307 is installed on the worm reducer 301 , and one end of the screw 305 is arranged in the protective member 307 for protecting the screw 305 .

[0065] like Figures 1 to 9 As shown, the tension and compression sensor 4 is installed on the buffer mechanism 306 and is electrically connected to the control box. It is used to monitor the thrust changes during the tightening process in real time and feed back to the control system. A contact plate 401 is installed on the tension and compression sensor 4, and the contact plate 401 corresponds to the telescopic tail top piece 202.

[0066] In specific use, when it is necessary to control the telescopic tail top piece 202 to be lifted, the servo motor 304 is operated, the servo motor 304 drives the worm 302 to rotate, and the worm 302 drives the linkage gear 303 to rotate. Since the screw 305 is threadedly connected to the linkage gear 303, the screw 305 can move. The screw 305 then lifts the telescopic tail top piece 202 through the buffer mechanism 306.

[0067] This application uses a servo motor 304 to drive a worm reducer 301, in combination with a tension and compression sensor 4 and a closed-loop control system. Compared with traditional hydraulic systems, it has significant advantages in terms of accuracy, response speed, and stability. First, for high-precision force control, the servo motor 304 and the tension and compression sensor 4 are combined to achieve closed-loop control. Users can set the target tightening force on the HMI interface of the closed-loop control system, and the closed-loop control system automatically adjusts the output of the servo motor 304 to ensure that the tightening force is stable and reliable. Second, for real-time thrust monitoring, the tension and compression sensor 4 continuously feeds back data, making the tightening process transparent and improving safety and intelligence. In addition, this application is fully electrically driven, eliminating the hydraulic station and its related maintenance components, eliminating the risk of oil leakage, and reducing environmental protection pressure. It is more suitable for application scenarios with high requirements for force control accuracy compared to hydraulic systems, improving overall performance and reliability.

[0068] Application Example 1 (maximum thrust 5000N, die diameter 800mm):

[0069] The device uses a 1.5kW servo motor 304, in combination with a 20:1 worm reducer 301, and the range of the tension and compression sensor 4 is 10kN. The target thrust is set at 4000N, and the system automatically controls the output of the servo motor 304. After the thrust reaches the target value, the output is maintained stable. The fluctuation range in 10 tests is less than ±40N, and the clamping effect is consistent.

[0070] Application Example 2 (maximum thrust 12000N, die diameter 1600mm):

[0071] Replace it with a 3.0kW servo motor 304 and a higher load-bearing worm group, and use a 20kN tension and compression sensor 4. Set the stepped loading control logic through the PLC, and complete the loading process in 4 levels within 5s. It is found in the test that the loading error at each stage does not exceed ±1%, and the thrust change response time <80ms.

[0072] Application Example 3 (verification of dynamic adjustment function):

[0073] During the winding process, simulate the micro-displacement of the die, causing a thrust fluctuation of about 200N. The system adjusts the output within 0.2s and stabilizes back to the set thrust again, proving that this system has good dynamic response and real-time correction capabilities.
