Description

Technical Field

[0001] This utility model belongs to the technical field of end cap pressing equipment, specifically relating to an automatic pressing mechanism for flexible end caps. Background Technology

[0002] Existing main pipe pressing equipment is mostly single-function and lacks automated conveying and station transfer mechanisms. After completing the first pressing step, the pipe body needs to be manually moved to another pressing station. This not only increases labor intensity but also easily causes damage to the pipe body by bumping and knocking. It also limits the improvement of production efficiency. Furthermore, traditional main pipe pressing lacks precise positioning and inspection methods, making it difficult to ensure the concentricity and depth of pressing. This can easily lead to improper installation of copper rings or end caps, affecting product performance and quality. Moreover, relying on manual inspection to check whether the pressing is in place is not only inefficient but also prone to misjudgment. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an automatic pressing mechanism for flexible end caps.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic pressing mechanism for flexible end caps, comprising a pressing frame body, an end cap pressing plate provided on one side of the upper end of the pressing frame body via a positioning connection structure, a first pressing station group provided on one end of the upper side of the end cap pressing plate along the width direction for placing a main tube body and pressing copper rings located at both ends of the main tube body into the inner sides of both ends of the main tube body, a second pressing station group provided on one side of the first pressing station group for placing a main tube body with pressed copper rings and pressing end caps located at both ends of the main tube body with pressed copper rings to both ends of the main tube body, a main tube unloading conveying structure provided between the first pressing station group and the second pressing station group for conveying the main tube body with pressed copper rings from the first pressing station group to the second pressing station group, and a station drive detection mechanism connected to the first pressing station group and the second pressing station group respectively provided on both ends of the pressing frame body near the end cap pressing plate. This device features product versatility, ease of operation, automatic detection of copper ring presence, automatic detection of end cap pressure, prevention of incorrect end cap placement, and control of end cap insertion depth.

[0005] In the aforementioned flexible end cap automatic pressing mechanism, the lower end of the pressing frame body has a lower frame, and the upper end of the lower frame has an upper frame. A pressing installation groove is provided in the middle of one side of the upper frame, and an opening is provided on one side of the pressing installation groove. The end cap pressing plate is disposed within the pressing installation groove. A station drive base plate is located between the upper and lower frames on the side of the upper frame near the pressing installation groove, and the end cap pressing plate is located in the middle of the station drive base plate. This layered design ensures the rigidity and stability of the overall structure, effectively absorbing vibrations generated during the pressing process. The pressing installation groove provides a precise installation position and containment space for the end cap pressing plate, ensuring the alignment of the core working unit and laying the foundation for the accuracy of the entire equipment.

[0006] In the above-mentioned flexible end cap automatic pressing mechanism, the first pressing station group has copper ring pressing stations respectively set at both ends of the end cap pressing plate along the length direction, and the second pressing station group has end cap pressing stations respectively set on one side of the copper ring pressing stations. There is a copper ring pressing space between the two copper ring pressing stations and an end cap pressing space between the two end cap pressing stations. The upper end of the copper ring pressing station near the copper ring pressing space is provided with a copper ring pressing rod, and the upper end of the end cap pressing station near the end cap pressing space is provided with an end cap pressing rod. One end of the end cap has a closed plane and the other end has a recessed groove. The recessed groove of the end cap is set towards the main body, and one end of the end cap pressing rod of the end cap pressing station is provided with a pressing boss corresponding to the closed plane. The copper ring pressing and end cap pressing are separated into two independent workstation groups, which allows for independent parameter settings and optimization for different pressing processes. At the same time, the pressing boss has a mistake prevention function. If the end cap is installed backwards, the pressing boss will extend into the recessed groove of the end cap during the pressing of the end cap. In this way, the extension of the end cap pressing rod will exceed the set range of the displacement sensor and trigger an alarm.

[0007] In the aforementioned flexible end cap automatic pressing mechanism, the main pipe unloading and conveying structure includes several drive columns disposed in the middle of the copper ring pressing space and connected to the end cap pressing plate. A main pipe conveying seat is movably mounted at the lower end of each drive column. An inclined main pipe slide bar is provided on one side of each end of the main pipe conveying seat. The end of the main pipe slide bar away from the main pipe conveying seat extends into the end cap pressing space. Main pipe positioning blocks corresponding to the ends of the main pipe slide bars are respectively provided at both ends of the copper ring pressing space and the end cap pressing space. A conveying drive assembly is provided between the main pipe conveying seat and the end cap pressing plate. This achieves seamless connection and automated flow of the main pipe between two workstations, eliminating manual handling, greatly improving production efficiency and ensuring process consistency. Furthermore, the use of inclined slide bars and positioning blocks results in a simple and reliable structure, achieving low-cost and high-efficiency material transfer.

[0008] In the aforementioned flexible end cap automatic pressing mechanism, the main guide slide rod is provided with a sliding limit part at one end near the end cap pressing space. The main guide slide rod gradually slopes downwards from one end near the copper ring pressing space to the other end. Both the main guide positioning block at one end of the copper ring pressing space and the main guide positioning block at one end of the end cap pressing space are equipped with main guide positioning sensors. The sliding limit part and the inclined design of the main guide slide rod fully utilize gravity for conveying, which is energy-saving and reliable. Simultaneously, the introduction of the main guide positioning sensor is key to achieving automated control. It can detect in real time whether the workpiece has accurately reached the predetermined position, providing a safety interlock signal for the next pressing action, avoiding misoperation and equipment collisions, and improving the safety and reliability of the system.

[0009] In the aforementioned automatic pressing mechanism for flexible end caps, the conveying drive assembly includes several drive holes located on the inner side of the bottom of the main conveyor seat. The main conveyor seat is connected to a drive column through the drive holes. A limiting plate is provided between the upper ends of the drive column. A return spring located on the outer circumference of the drive column is provided between the main conveyor seat and the limiting plate. A drive cylinder is provided in the middle of the lower side of the workstation drive base plate. The piston rod of the drive cylinder passes through the workstation drive base plate and the end cap pressing plate axially upwards and is connected to the main conveyor seat. A cylinder connection part connected to the drive cylinder is provided on the inner side of the workstation drive base plate. The cylinder, as a power source, has a fast response and is simple to control. The design of the return spring is particularly important, as it ensures that the conveyor seat can automatically and smoothly return to its original position after being pushed. At the same time, the cooperation between the drive column and the drive hole has good guiding properties, ensuring the accuracy of the movement trajectory.

[0010] In the aforementioned flexible end cap automatic pressing mechanism, the station drive detection mechanism includes copper ring station hydraulic cylinders respectively installed at both ends of the upper side of the station drive base plate. An end cap station hydraulic cylinder is located on one side of each copper ring station hydraulic cylinder. The output shaft of the copper ring station hydraulic cylinder is connected to the end of the copper ring pressure rod furthest from the main body, and the output shaft of the end cap station hydraulic cylinder is connected to the end of the end cap pressure rod furthest from the main body. Both the copper ring station hydraulic cylinder and the end cap station hydraulic cylinder are equipped with sensor detection components. Using hydraulic cylinders as the power source provides a large and stable pressing force, making it ideal for pressing and assembling metal parts. The independent drive cylinders for different stations demonstrate modularity, facilitating independent maintenance and parameter adjustment, and improving the maintainability and flexibility of the equipment.

[0011] In the aforementioned automatic pressing mechanism for flexible end caps, the sensor detection assembly includes a pressure sensor located at the end of the hydraulic cylinder near the end cap pressing station, and displacement sensors located on both sides of the hydraulic cylinder at the copper ring station and the end cap station. The combined use of the pressure and displacement sensors enables real-time monitoring and quality control of the pressing process. The pressure sensor ensures the pressing force is within a reasonable range, preventing insufficient or excessive pressure, while the displacement sensor ensures the pressing depth meets process requirements. Furthermore, the displacement sensor on the copper ring station hydraulic cylinder detects whether the copper ring has been pressed in, and the pressure sensor on the end cap station hydraulic cylinder monitors the end cap pressing force, thus protecting the end cap.

[0012] In the aforementioned automatic pressing mechanism for flexible end caps, the positioning connection structure includes end positioning reference blocks arranged laterally at both ends of the pressing installation groove away from the opening. Side positioning reference blocks are arranged longitudinally at both ends of the pressing installation groove, near the opening. The end cap pressing plate contacts both the end positioning reference blocks and the side positioning reference blocks on its circumferential outer side. One end positioning reference block has a tooling identification sensor on one side, and a positioning connection assembly is provided between the end cap pressing plate and the station drive base plate. The end positioning reference blocks and the side positioning reference blocks together constitute a precise positioning system, ensuring extremely high positioning accuracy during end cap pressing plate installation.

[0013] In the above-mentioned flexible end cap automatic pressing mechanism, the positioning connection component includes a number of pressing plate connection holes disposed on the inner side of the end cap pressing plate, and the center inner side of the station drive base plate is provided with a number of pressing plate fixing holes corresponding one-to-one with the pressing plate connection holes, and the pressing plate connection holes are connected to the pressing plate fixing holes by connecting bolts.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. This device adopts dual-station linkage and automatic conveying to realize the full-process automation from copper ring pressing to end cap pressing. The first pressing station group and the second pressing station group cooperate synchronously, and then the main tube unloading conveying structure is used to automatically transport the main tube body with pressed copper ring from the first station to the second station, avoiding the problems of low efficiency and bump damage caused by manual handling, while improving production efficiency.

[0015] 2. This device utilizes a station-driven detection mechanism, integrating pressure and displacement sensors, to monitor the force and displacement of each pressing operation in real time. This enables quantitative pressing and online quality inspection. If abnormal pressure or inadequate displacement occurs, the system can immediately alarm and stop, effectively preventing the generation of batch defective products and ensuring product quality consistency.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-7As shown, an automatic pressing mechanism for flexible end caps includes a pressing frame body 1. An end cap pressing plate 3 is provided on one side of the upper end of the pressing frame body 1 via a positioning connection structure 2. A first pressing station group 31 is provided on one end of the upper side of the end cap pressing plate 3 along its width direction for placing a main tube body 11 and pressing copper rings 111 located at both ends of the main tube body 11 into the inner sides of both ends of the main tube body 11. A side of the first pressing station group 31 is provided for placing the main tube body 11 with the pressed copper rings 111 and pressing the copper rings 111 into the inner sides of both ends of the main tube body 11. The end caps 112 at both ends of the main pipe body 11 are press-fitted to the second pressing station group 32 at both ends of the main pipe body 11. A main pipe unloading conveying structure 4 is provided between the first pressing station group 31 and the second pressing station group 32 to transport the main pipe body 11 with the press-fitted copper rings 111 from the first pressing station group 31 to the second pressing station group 32. The pressing machine frame body 1 has station drive detection mechanisms 5 at both ends near the end cap pressing plate 3, which are connected to the first pressing station group 31 and the second pressing station group 32 respectively. This device has the characteristics of product versatility, convenient operation, automatic detection of the presence or absence of copper rings 111, automatic detection of end cap 112 pressure, prevention of incorrect placement of end caps 112, and control of end cap 112 pressing depth.

[0026] like Figure 1 As shown, the lower end of the press-fitting machine frame 1 has a lower frame 12, and the upper end of the lower frame 12 has an upper frame 13. A press-fitting mounting groove 14 is provided in the middle of one side of the upper frame 13, and an opening 15 is provided on one side of the press-fitting mounting groove 14. The end cap press-fitting plate 3 is installed inside the press-fitting mounting groove 14. A station drive base plate 16 is located between the upper frame 13 and the lower frame 12 on the side of the upper frame 13 near the press-fitting mounting groove 14, and the end cap press-fitting plate 3 is located in the middle of the station drive base plate 16. This layered design ensures the rigidity and stability of the overall structure and effectively absorbs vibrations generated during the press-fitting process. The design of the press-fitting mounting groove 14 provides a precise installation position and containment space for the end cap press-fitting plate 3, ensuring the alignment of the core working unit and laying the foundation for the accuracy of the entire equipment.

[0027] Combination Figures 4-7As shown, the first pressing station group 31 has copper ring pressing stations 33 respectively set at both ends of the end cap pressing plate 3 along the length direction, and the second pressing station group 32 has end cap pressing stations 34 respectively set on one side of the copper ring pressing station 33. There is a copper ring pressing space between the two copper ring pressing stations 33 and an end cap pressing space between the two end cap pressing stations 34. A copper ring pressing rod 331 is provided at the upper end of the side of the copper ring pressing station 33 near the copper ring pressing space, and an end cap pressing rod 341 is provided at the upper end of the side of the end cap pressing station 34 near the end cap pressing space. One end of the end cap 112 has a closed plane 113 and the other end has a recessed groove 114. The recessed groove 114 of the end cap 112 is set towards the main body 11, and one end of the end cap pressing rod 341 of the end cap pressing station 34 is provided with a pressing boss 36 corresponding to the closed plane 113. The copper ring pressing and end cap pressing are separated into two independent workstation groups, which allows for independent parameter settings and optimization for different pressing processes. At the same time, the pressing boss 36 has a mistake prevention function. If the end cap 112 is installed backwards, the pressing boss 36 will extend into the recessed groove 114 of the end cap 112 during the pressing of the end cap 112. In this way, the extension of the end cap pressing rod 341 will exceed the set range of the displacement sensor 72 and trigger an alarm.

[0028] The main pipe unloading and conveying structure 4 includes several drive columns 41 located in the middle of the copper ring pressing space and connected to the end cap pressing plate 3. A main pipe conveying seat 42 is movably mounted at the lower end of each drive column 41. An inclined main pipe slide rod 43 is mounted on one side of each end of the main pipe conveying seat 42. The end of the main pipe slide rod 43 away from the main pipe conveying seat 42 extends into the end cap pressing space. Main pipe positioning blocks 44, corresponding to the ends of the main pipe slide rods 43, are respectively located at both ends of the copper ring pressing space and the end cap pressing space. A conveying drive assembly 6 is located between the main pipe conveying seat 42 and the end cap pressing plate 3. This achieves seamless connection and automated flow of the main pipe body 11 between the two workstations, eliminating manual handling, greatly improving production efficiency and ensuring process consistency. Furthermore, the use of inclined slide rods and positioning blocks results in a simple and reliable structure, achieving low-cost and high-efficiency material transfer.

[0029] Specifically, the main guide rail 43 has a sliding limit part 45 at one end near the end cap pressing space. The main guide rail 43 gradually slopes downward from one end near the copper ring pressing space to the other end. Both the main guide positioning block 44 at one end of the copper ring pressing space and the main guide positioning block 44 at one end of the end cap pressing space are equipped with main guide positioning sensors 46. The sliding limit part 45 and the inclined design of the main guide rail 43 fully utilize gravity for conveying, which is energy-saving and reliable. Meanwhile, the introduction of the main guide positioning sensor 46 is key to achieving automated control. It can detect in real time whether the workpiece has accurately reached the predetermined position, providing a safety interlock signal for the next pressing action, avoiding misoperation and equipment collisions, and improving the safety and reliability of the system.

[0030] Meanwhile, the conveying drive assembly 6 includes several drive holes 61 located on the inner side of the bottom of the main conveyor seat 42. The main conveyor seat 42 is connected to the drive column 41 through the drive holes 61. A limiting plate 62 is provided between the upper ends of the drive column 41. A return spring 63 located on the outer side of the drive column 41 is provided between the main conveyor seat 42 and the limiting plate 62. A drive cylinder 64 is provided in the middle of the lower side of the station drive base plate 16. The piston rod of the drive cylinder 64 passes through the station drive base plate 16 and the end cover press plate 3 axially upward and is connected to the main conveyor seat 42. A cylinder connection part 65 connected to the drive cylinder 64 is provided on the inner side of the station drive base plate 16. The cylinder, as a power source, has a fast response and is simple to control. The design of the return spring 63 is particularly important. It ensures that the conveyor seat can automatically and smoothly return after pushing. At the same time, the cooperation between the drive column 41 and the drive hole 61 has good guiding properties, ensuring the accuracy of the motion trajectory.

[0031] like Figure 3 As shown, the station drive detection mechanism 5 includes copper ring station hydraulic cylinders 51 respectively installed at both ends of the upper side of the station drive base plate 16. An end cap station hydraulic cylinder 52 is provided on one side of each copper ring station hydraulic cylinder 51. The output shaft of the copper ring station hydraulic cylinder 51 is connected to the end of the copper ring pressure rod 331 away from the main body 11, and the output shaft of the end cap station hydraulic cylinder 52 is connected to the end of the end cap pressure rod 341 away from the main body 11. Both the copper ring station hydraulic cylinder 51 and the end cap station hydraulic cylinder 52 are equipped with sensor detection components 7. Using hydraulic cylinders as the power source provides a large and stable pressing force, making it very suitable for pressing and assembling metal parts. The independent drive cylinders for different stations reflect modularity, facilitating independent maintenance and parameter adjustment, and improving the maintainability and flexibility of the equipment.

[0032] The sensor detection component 7 includes a pressure sensor 71 located at the end of the end cap station hydraulic cylinder 52 near the end cap pressing station 34, and displacement sensors 72 located on both sides of the copper ring station hydraulic cylinder 51 and the end cap station hydraulic cylinder 52. The combined use of the pressure sensor 71 and displacement sensor 72 enables real-time monitoring and quality control of the pressing process. The pressure sensor 71 ensures the pressing force is within a reasonable range, preventing insufficient or excessive pressure. The displacement sensor 72 ensures the pressing depth meets process requirements. Furthermore, the displacement sensor 72 of the copper ring station hydraulic cylinder 51 is used to detect whether the copper ring 111 is pressed in, and the pressure sensor 71 of the end cap station hydraulic cylinder 52 is used to monitor the pressing force of the end cap 112, thus protecting the end cap 112.

[0033] Combination Figure 2 and Figure 3As shown, the positioning connection structure 2 includes end positioning reference blocks 21 arranged laterally at both ends of the press-fit mounting groove 14 away from the opening 15, and side positioning reference blocks 22 arranged longitudinally at both ends of the press-fit mounting groove 14 near the opening 15. The end cap press-fit plate 3 contacts the end positioning reference blocks 21 and the side positioning reference blocks 22 on its outer periphery. One of the end positioning reference blocks 21 is equipped with a tooling identification sensor 23 on one side, and a positioning connection assembly 8 is provided between the end cap press-fit plate 3 and the station drive base plate 16. The end positioning reference blocks 21 and the side positioning reference blocks 22 together form a precise positioning system, ensuring that the end cap press-fit plate 3 can achieve extremely high positioning accuracy during installation.

[0034] The positioning connection assembly 8 includes several pressure plate connection holes 81 disposed inside the end cover pressure plate 3, and several pressure plate fixing holes 82 corresponding to the pressure plate connection holes 81 are provided on the inner side of the middle part of the station drive base plate 16, and the pressure plate connection holes 81 are connected to the pressure plate fixing holes 82 by connecting bolts.

[0035] The principle of this embodiment is as follows: The end cap pressing plate 3 is fixed in the pressing installation groove 14 of the pressing machine frame body 1 through the positioning connection structure 2. Its outer circumferential side is in close contact with the transverse end positioning reference block 21 and the longitudinal side positioning reference block 22 to determine the installation reference. The first pressing station group 31 is responsible for pressing the copper ring 111 into the inner sides of both ends of the main tube body 11. The copper ring station hydraulic cylinder 51 in the station drive detection mechanism 5 is started, and its output shaft pushes the copper ring pressing rod 331 on the copper ring pressing station 33 to move towards the main tube body 11 in the copper ring pressing space. The copper ring pressing rod 331 accurately pushes the copper ring 111 into the inner sides of both ends of the main tube body 11, completing the copper ring pressing. During the pressing process... The displacement sensor 72 on the hydraulic cylinder 51 at the copper ring station detects the movement distance of the pressure rod to ensure that the pressing depth meets the standard. If an abnormality occurs, the mechanism will automatically stop. After the copper ring is pressed, the main pipe unloading and conveying structure 4 conveys the main pipe body 11 with the copper ring from the first station to the second station without manual intervention. The drive cylinder 64 in the conveying drive assembly 6 is activated, and its piston rod passes upward through the station drive base plate 16 and the end cover pressing plate 3, pushing the main pipe conveying seat 42 to move upward along the drive column 41. The inclined main pipe slide rods 43 at both ends of the main pipe conveying seat 42 lift the main pipe body 11 in the copper ring pressing space. Then the main pipe body 11 moves along the main pipe slide rods 43. The main pipe 11 slides into the end cap pressing space of the second pressing station group 32. After sliding into the end cap pressing space, it is precisely limited by the main pipe positioning blocks 44 at both ends. At the same time, the main pipe positioning sensor 46 in the end cap pressing space detects whether the main pipe 11 is in position. After it is in position, it sends a signal to trigger the next action. The piston rod of the drive cylinder 64 retracts, and the main pipe conveying seat 42 falls back along the drive column 41 under the reset force of the reset spring 63, returning to the initial position and waiting for the next conveying. After the main pipe 11 with copper rings is in position, the second pressing station group 32 is responsible for pressing the end cap 112 onto both ends of the main pipe 11. The end cap station hydraulic cylinder in the station drive detection mechanism 5 When the 52 is started, its output shaft pushes the end cap pressing rod 341 on the end cap pressing station 34 to move towards the main body 11 in the end cap pressing space. The pressing boss 36 at one end of the end cap pressing rod 341 is precisely fitted with the closed plane 113 of the end cap 112, pushing the end cap 112 towards the main body 11 to complete the end cap pressing. The pressure sensor 71 detects the pressure value during the pressing process to avoid excessive pressure damaging the parts or insufficient pressure causing loose assembly. The displacement sensor 72 detects the moving distance of the end cap pressing rod 341 to ensure that the pressing depth of the end cap 112 meets the requirements. After the finished product is removed, the mechanism automatically resets to the initial state to realize continuous automated production.
