Description

Technical Field

[0001] This utility model relates to the field of hydraulic joint processing technology, and in particular to an automatic tightening and assembly workbench for multi-port hydraulic joints. Background Technology

[0002] Currently, in the field of industrial hydraulic systems, multi-port hydraulic couplings are core components that enable the free conversion and connection of multiple media channels. They play an indispensable supporting role in the stable operation of hydraulic systems. From a structural and performance perspective, this coupling integrates multiple independent channels, which can simultaneously transport various different media such as hydraulic oil, water, and air. It can also strictly ensure the isolation between the media, effectively avoiding the mixing of media, thereby ensuring the stability and independence of the media transmission process in the hydraulic system. This lays the foundation for the reliable operation of hydraulic equipment. To meet the sealing requirements of hydraulic systems, multi-port hydraulic couplings adopt a special sealing structure design, which has excellent sealing performance and can significantly reduce the risk of media leakage and reduce system failures caused by leakage. Meanwhile, the connector is equipped with high-precision bearing components, which not only makes its operation more stable, but also significantly reduces the wear rate of components and greatly extends its service life. With these excellent characteristics, the multi-port hydraulic connector has a wide range of applications, covering industrial production equipment such as machining center rotary tables, hydraulic workstations, and coilers, as well as engineering machinery equipment such as excavators and cranes. It is also suitable for various multi-channel high-pressure control equipment. In addition, in response to the complex working conditions of different industries, the multi-port hydraulic connectors on the market show a variety of differences in core parameters such as the number of channels, working pressure tolerance, operating speed range, and applicable temperature range, which can accurately adapt to the usage needs of different scenarios and further expand its application coverage.

[0003] However, in the production and processing of multi-port hydraulic couplings, especially during assembly, specialized tightening equipment is essential to ensure the assembly accuracy and connection reliability of the couplings. However, existing tightening equipment in the industry exhibits significant defects and shortcomings when applied to multi-port hydraulic coupling assembly. Specifically, the tightening structure of existing equipment has design limitations; its spacing is fixed and cannot be flexibly adjusted according to the specifications of the multi-port hydraulic couplings. When assembling multi-port hydraulic couplings of different sizes, the equipment cannot adjust the inner spacing of the tightening structure. Workers must replace the tightening structure with one of the corresponding specifications to fit the different sizes of couplings. This process not only increases the time cost of equipment adjustment, leading to decreased assembly efficiency, but also makes the overall processing flow cumbersome and complex, severely disrupting the continuity of multi-port hydraulic coupling production and assembly, and making it difficult to meet the mass production needs of enterprises for diverse specifications of multi-port hydraulic couplings. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automatic tightening assembly workbench for multi-port hydraulic joints, which can more accurately solve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes an automatic tightening assembly workbench for multi-port hydraulic connectors, including a base, mounting plates fixedly installed on both sides of the top of the base, a clamping assembly fixedly installed at the lower end of the mounting plates, a frame fixedly installed on the top of the mounting plates, a telescopic module fixedly installed in the middle of the top of the frame, and a tightening module fixedly installed at the bottom of the telescopic module.

Each adjustable limit group is connected by transmission components. The rear side of the adjustment component is connected to the front end of the adjustable limit group.

[0008] Furthermore, the clamping assembly includes a mounting side seat, which is fixedly mounted on the lower end of the mounting plate. A first electric push rod is fixedly mounted on the outer side of the mounting side seat, and a clamping plate is fixedly mounted on the output end of the first electric push rod. A clamping frame is fixedly mounted on the inner side of the clamping plate.

[0009] Furthermore, the telescopic module includes a mounting base, which is fixedly installed at the top center of the frame.

[0010] Furthermore, a support plate is fixedly installed on the outer side of the mounting sleeve, and support rods are fixedly installed at both ends of the top of the support plate. The ends of the support rods penetrate the mounting base, and the support rods and the mounting base are slidably connected. A placement plate is fixedly installed in the middle of the top of the base, and mounting holes are provided at the four corners of the top of the base. The mounting holes are countersunk holes.

[0011] Furthermore, the adjustable limiting assembly includes a lead screw, which is rotatably connected to the inside of a slide groove. A slider is threadedly connected to the outer surface of the lead screw, and the slider is slidably connected to the inside of the slide groove. A tightening limiting plate is fixedly installed at the bottom of the slider. The inner end of the lead screw is connected to a transmission assembly, and a reinforcing plate is fixedly installed on the outer side of the tightening limiting plate.

[0012] Furthermore, the transmission assembly includes a hexagonal groove, which is located at the bottom center of the fixed base. Side bevel gears are rotatably connected to the interior of the hexagonal groove in a ring with equal spacing. A main bevel gear is rotatably connected to the upper end of the interior of the hexagonal groove. The main bevel gear and the side bevel gear are meshed together. The outer side of the side bevel gear is fixedly connected to the inner end of the lead screw.

[0013] Furthermore, the adjustment assembly includes a fixed plate, which is fixedly installed on the front of the fixed base.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] An automatic tightening assembly workbench for multi-port hydraulic connectors includes a base 1, mounting plates 2 are fixedly installed on both sides of the top of the base 1, clamping components 3 are fixedly installed at the lower end of the mounting plates 2, a frame 4 is fixedly installed on the top of the mounting plates 2, a telescopic module 5 is fixedly installed in the middle of the top of the frame 4, and a tightening module 6 is fixedly installed at the bottom of the telescopic module 5.

[0025] The tightening module 6 includes a drive motor 61, which is fixedly installed at the bottom of the telescopic module 5. A fixed base 62 is fixedly installed at the output end of the drive motor 61. The bottom of the fixed base 62 has equally spaced, ring-shaped grooves 63. Adjustable limit groups 64 are movably installed inside the grooves 63. An adjustment component 65 is fixedly installed in the center of the front of the fixed base 62, and a transmission component 66 is located in the center of the inner side of the fixed base 62. Each adjustable limit group 64 is connected via the transmission component 66. The rear of the adjustment component 65 is connected to the front of the adjustable limit group 64. During application, the multi-port hydraulic connector to be assembled is first placed on the base 1. Then, the clamping component 3 is activated, which securely clamps the workpiece, preventing displacement during subsequent tightening operations. This design effectively improves the stability of the assembly process and solves the problem of insufficient assembly accuracy caused by easy workpiece displacement in existing technologies. After the workpiece is fixed, the telescopic module 5 at the top center of the frame 4 begins to operate, driving the tightening module at the bottom. Module 6 moves downwards until the tightening part of the screwing module 6 and the workpiece are at the appropriate height. This process eliminates the need for repeated manual height adjustments, significantly saving operation time and improving overall operational efficiency. The drive motor 61 in the screwing module 6 then starts, and the output of the drive motor 61 drives the fixed base 62 to rotate. When the fixed base 62 rotates, it synchronously drives the adjustable limit group 64 at the bottom to move. Since the adjustable limit group 64 is connected to the transmission component 66 and the adjustment component 65 is connected to the front end of the adjustable limit group 64, the operator can adjust the position of the adjustable limit group 64 in the slide groove 63 in advance through the adjustment component 65, so that the adjustable limit group 64 can adapt to the tightening requirements of multi-port hydraulic joints of different specifications without replacing the core components of the screwing module 6. This significantly enhances the versatility of the device and solves the problem in the prior art that it cannot adapt to multiple specifications of workpieces due to the fixed structure. Finally, the adjustable limit group 64 rotates with the fixed base 62 to complete the tightening operation of the workpiece. The whole process is smooth and orderly, which can effectively ensure assembly quality and efficiency.

[0026] Combination Figures 1-3As shown, the clamping assembly 3 includes a mounting side seat 31, which is fixedly mounted on the lower end of the mounting plate 2. A first electric push rod 32 is fixedly mounted on the outer side of the mounting side seat 31. A clamping plate 33 is fixedly mounted on the output end of the first electric push rod 32. A clamping frame 34 is fixedly mounted on the inner side of the clamping plate 33. The telescopic module 5 includes a mounting base 51, which is fixedly mounted on the top center of the frame 4. A second electric push rod 52 is fixedly mounted on the top of the mounting base 51. The output end of the second electric push rod 52... A movable base 53 is fixedly installed, and an installation sleeve 54 is fixedly installed at the bottom of the movable base 53. A drive motor 61 is fixedly installed inside the installation sleeve 54. A support plate 55 is fixedly installed on the outside of the installation sleeve 54. Support rods 56 are fixedly installed at both ends of the top of the support plate 55. The ends of the support rods 56 pass through the mounting base 51. The support rods 56 and the mounting base 51 are slidably connected. A placement plate 7 is fixedly installed in the middle of the top of the base 1. Mounting holes 8 are opened at the four corners of the top of the base 1. The mounting holes 8 are countersunk holes.

[0027] In the above-described embodiments of this application, during the application of this device, the overall fixation is first completed through the countersunk holes at the four corners of the top of the base 1. The countersunk holes can prevent the heads of the fixing bolts from protruding and interfering with the operation. Then, the multi-port hydraulic connector to be assembled is placed on the placement plate 7 in the middle of the top of the base 1. The placement plate 7 can perform preliminary positioning of the workpiece, reduce subsequent adjustment time, and improve the efficiency of the work preparation stage. Next, the clamping assembly 3 is activated. The fixing seat 62 of the clamping assembly 3 provides the installation base. The output end of the first electric push rod 32 on its outer side extends, pushing the clamping plate 33 to move towards the workpiece. The clamping plate 33 drives the inner clamping frame 34 to move synchronously. Finally, the clamping frame 34 contacts the workpiece and achieves stable clamping. This process is provided with stable power by the electric push rod, which can effectively avoid manual clamping compared to manual clamping. The component displacement addresses the problem of insufficient assembly accuracy caused by unstable clamping in existing technologies. After the workpiece is fixed, the telescopic module 5 at the top center of the frame 4 begins to work. The mounting base 51 of the telescopic module 5 supports the overall structure, and the output end of the second electric push rod 52 at its top extends, pushing the moving seat 53 downward. The moving seat 53 drives the mounting sleeve 54 at the bottom and the drive motor 61 inside the mounting sleeve 54 to descend synchronously. At the same time, the support rod 56 at the top of the outer support plate 55 of the mounting sleeve 54 slides along the mounting base 51, providing precise guidance for the lifting and lowering of the moving seat 53, preventing the drive motor 61 from deviating during descent, ensuring the alignment accuracy of subsequent tightening operations, and avoiding operational errors caused by positional deviations. The entire process does not require manual intervention for height adjustment, greatly saving operation time and further improving overall work efficiency.

[0028] Example 2

[0029] Combination Figures 2-4As shown, the adjustable limiting assembly 64 includes a lead screw 641, which is rotatably connected to the inside of the slide groove 63. A slider 642 is threadedly connected to the outer surface of the lead screw 641, and the slider 642 is slidably connected to the inside of the slide groove 63. A tightening limiting plate 643 is fixedly installed at the bottom of the slider 642. The inner end of the lead screw 641 is connected to the transmission assembly 66. A reinforcing plate 644 is fixedly installed on the outer side of the tightening limiting plate 643. The transmission assembly 66 includes a hexagonal groove 661, which is located in the middle of the bottom of the fixed seat 62. A side bevel gear 662 is rotatably connected to the hexagonal groove 661 in a ring with equal spacing inside the hexagonal groove 661. The upper part of the inner part of 61 is rotatably connected to a main bevel gear 663, which meshes with a side bevel gear 662. The outer side of the side bevel gear 662 is fixedly connected to the inner end of the lead screw 641. The adjusting assembly 65 includes a fixed plate 651, which is fixedly installed on the front of the fixed base 62. An adjusting handle 652 is rotatably connected to the front of the fixed plate 651. The upper end of the adjusting handle 652 is threadedly connected to a limit screw 653. Limiting holes 654 are arranged in a ring at equal intervals on the front of the fixed plate 651. The end of the limit screw 653 is inserted into the limit hole. The limit screw 653 is a hand-tightening screw.

[0030] In the above-described embodiments of this application, when the device needs to be adjusted according to the specifications of the multi-port hydraulic connector to be assembled, the operator first operates the adjustment component 65. Since the limit screw 653 is designed to be hand-tightened, it can be loosened without the aid of additional tools, allowing the end of the limit screw 653 to disengage from the limit locking hole 654 of the fixed plate 651. This design greatly simplifies the preparation operation before adjustment and improves the adjustment efficiency. Then, the adjustment handle 652 on the front of the fixed plate 651 is rotated. The movement of the adjustment handle 652 will drive the transmission component 66 to rotate. The hexagonal groove 661 of the transmission component 66 provides a stable working space for the internal gears. The main bevel gear 663 rotates in the hexagonal groove 661 with the adjustment movement. Because the main bevel gear 663 meshes with the side bevel gear 662, the main bevel gear 663 will drive the equally spaced annularly arranged side bevel gears 662 to rotate synchronously. The side bevel gears 662 then drive the lead screw 641 connected to them to rotate. When the screw 641 rotates within the slide groove 63, the slider 642, which is threaded to its outer surface, slides along the slide groove 63. The slider 642 drives the bottom tightening limit plate 643 to move synchronously, thereby adjusting the spacing between the tightening limit plates 643. Multiple adjustable limit groups 64 operate synchronously through the transmission component 66, ensuring uniform spacing adjustment and allowing the tightening limit plates 643 to precisely adapt to workpieces of different specifications. This eliminates the need to replace core components, meeting diverse assembly requirements and solving the problems of fixed structure and poor adaptability in existing technologies. After adjustment, the hand-tightened limit screw 653 is tightened in the reverse direction, causing its end to insert into the corresponding limit hole 654, fixing the position of the tightening limit plate 643 and preventing positional deviation during subsequent tightening operations. Simultaneously, the support plate 55 on the outer side of the tightening limit plate 643 enhances its structural strength, preventing deformation due to stress during tightening, ensuring the stability and precision of the assembly process, and further improving the overall assembly quality.

[0031] The working principle and advantages of this utility model are as follows: First, the workbench is fixed and the workpiece is initially placed. The operator uses bolts to fix the workbench in the designated working position through the mounting holes 8 at the four corners of the base 1. The countersunk mounting holes 8 ensure that the bolt heads are fully embedded during use, preventing the bolt heads from protruding from the base 1 surface and interfering with subsequent component operations or workpiece placement. The base 1, as the basic load-bearing structure of the entire device, provides stable support to ensure the orderly conduct of subsequent operations. After fixing the workbench, the operator places the multi-port hydraulic connector to be tightened onto the placement plate 7 in the middle of the top of the base 1. The placement plate 7 allows for initial positioning of the workpiece during use, effectively limiting its placement position on the base 1, thus providing a precise alignment basis for subsequent clamping and tightening operations. Compared to the prior art, which lacks precise initial positioning equipment, this design significantly reduces subsequent adjustment time and significantly improves overall work efficiency. Next, the clamping assembly 3 of this utility model is activated to fix the workpiece. Simultaneously, the cooperation between the mounting plate 2 and the frame 4 achieves a stable connection between the upper and lower components. The mounting plates 2 on both sides of the top not only serve to connect the clamping assembly 3 and the frame 4, providing support and fixation for the upper and lower components, but also provide a stable mounting foundation for the frame 4. The frame 4 further supports the telescopic module 5, ensuring its stable operation during subsequent operations. After the clamping assembly 3 is activated, the fixing seat 62 in the clamping assembly 3 first stably fixes the entire clamping structure to the lower end of the mounting plate 2, providing a solid foundation for the clamping operation. Subsequently, the output end of the first electric push rod 32 extends outward and pushes the clamping plate 33 towards the workpiece. The clamping plate 33 then moves the first electric push rod towards the workpiece. The power of the lever 32 is transmitted to the clamping frame 34, which drives the clamping frame 34 to move synchronously. Finally, the clamping frame 34 directly contacts the workpiece surface, and the workpiece is firmly clamped by the relative movement of the two clamping frames 34. By setting an independent clamping component 3, the workpiece displacement during subsequent tightening operations can be effectively prevented. This solves the problem of easy workpiece displacement and impact on assembly accuracy in the assembly process of existing equipment in the background art. At the same time, the stable clamping force provided by the first electric push rod 32 can further enhance the clamping stability and reduce assembly failures caused by unstable clamping compared to manual clamping or simple mechanical clamping.

[0032] Then, adjust the spacing of the adjustable limit group 64 of the screwing module 6 according to the workpiece specifications and dimensions, and lower the screwing module 6 to the position aligned with the workpiece via the telescopic module 5. When adjusting the spacing, the operator first loosens the hand-tightened limit screw 653 in the adjustment component 65, which can be completed without the need for additional tools. By setting the hand-tightened limit screw 653, the adjustment operation is more convenient during use, effectively improving the adjustment efficiency. After loosening, the end of the limit screw 653 exits through the limit hole 654 of the fixed plate 651. The fixing plate 651 not only fixes the overall position of the adjusting component 65, but also limits the rotation angle of the adjusting handle 652 through the limiting hole 654 to prevent over-adjustment. Then, the operator rotates the adjusting handle 652, which drives a connected lead screw 641 to rotate. The rotation of the lead screw 641 directly drives the side bevel gear 662 at its end to rotate. Since the side bevel gear 662 is meshed with the main bevel gear 663, the rotation of the side bevel gear 662 drives the main bevel gear 663 to rotate synchronously. The corner groove 661 provides installation space for the side bevel gear 662 and the main bevel gear 663, ensuring stable meshing and transmission. After the main bevel gear 663 rotates, it drives the other meshing side bevel gears 662 to rotate. These side bevel gears 662 then transmit power to the corresponding lead screws 641. Multiple lead screws 641 rotate synchronously within the slide groove 63. The slider 642, which is threaded to the outer surface of the lead screw 641, slides along the track direction of the slide groove 63 under the action of the rotation of the lead screw 641. The slider 642 then drives the bottom-fixed torque limit. The plate 643 moves synchronously, and the support plate 55 on the outside of the tightening limit plate 643 can enhance the structural strength of the tightening limit plate 643 and prevent it from deforming during subsequent tightening. Since the slide groove 63 is arranged in an evenly spaced ring at the bottom of the fixed seat 62, multiple adjustable limit groups 64 can move synchronously to achieve uniform adjustment of the spacing. Through this adjustment design, it can adapt to workpieces of different specifications without changing the tightening structure during use, and completely solve the problem of fixed spacing of the tightening structure and frequent replacement of the structure in the existing equipment in the background technology.After adjustment, the operator tightens the limiting screw 653 so that its end inserts into the corresponding limiting hole 654, thus fixing the position of the adjustable limiting group 64. Then, the telescopic module 5 is activated. The mounting base 51 in the telescopic module 5 first fixes the entire telescopic structure to the top of the frame 4. The output end of the second electric push rod 52 extends downward and pushes the moving seat 53 down. The moving seat 53 drives the drive motor 61 to descend synchronously through the mounting sleeve 54 fixed at the bottom. The support plate 55 on the outside of the mounting sleeve 54 fixes the support rod 56. The end of the support rod 56 passes through the mounting base 51 and maintains a sliding connection with the mounting base 51. Through the guiding action of the support rod 56, This design provides stable guidance for the lifting and lowering of the movable seat 53 during use, effectively preventing deviation during the descent of the movable seat 53. This ensures that the tightening module 6 can accurately align with the tightening part of the workpiece. This guiding design further improves alignment accuracy and reduces operational errors caused by alignment deviations. Finally, the tightening module 6 of this technical solution is activated to complete the workpiece tightening and perform subsequent reset operations. The drive motor 61 is fixed inside the mounting sleeve 54. After activation, its output end drives the fixed base 62 at the bottom to rotate. The fixed base 62, as the core load-bearing structure of the tightening module 6, also supports the adjustable limit group 64, the transmission assembly 66, and... The adjusting component 65 rotates synchronously with these components during rotation, thereby causing the tightening limit plate 643 in the adjustable limit group 64 to rotate as well. When the tightening limit plate 643 contacts the tightening part of the workpiece, continuous rotation achieves the tightening operation. After the tightening operation is completed, the output end of the second electric push rod 52 retracts, causing the moving seat 53, mounting sleeve 54, and drive motor 61 to rise and reset. Simultaneously, the output end of the first electric push rod 32 retracts, causing the clamping plate 33 and clamping frame 34 to move outwards, releasing the workpiece. The operator can then remove the assembled workpiece. Throughout the entire operation process, this technical solution... The flexible adjustment function of the adjustable limit group 64, combined with the stable clamping of the clamping component 3 and the precise guidance of the support rod 56, enables the device to adapt to multi-port hydraulic joints with different parameters mentioned in the background technology during use. This eliminates the need for separate equipment for different specifications of workpieces, significantly reducing production input costs. It also effectively ensures the continuity of production assembly and meets the mass production needs of diverse specifications of workpieces. At the same time, the structural design of each component emphasizes stability and durability. By enhancing structural strength and optimizing the transmission method, the overall stability and service life of the equipment are improved. Compared with existing equipment, the overall operating efficiency and assembly quality are significantly improved.

[0033] In this technical solution, the lead screw 641 is made of 304 stainless steel, which has the characteristics of corrosion resistance, high strength, and strong weather resistance, and can be used for a long time in air or water. Its diameter range is 8mm-12mm, the pitch range is 1mm-2mm, and the effective stroke range is 50mm-100mm. The side bevel gear 662 and the main bevel gear 663 are both made of 2Cr13 stainless steel, which also has the characteristics of corrosion resistance, high strength, and strong weather resistance, and can be used for a long time in air or water. The tooth count ranges from 1.5 to 2.5, the tooth count ranges from 15 to 25, and the tooth width ranges from 10mm to 15mm; the base 1 is made of Q235 steel plate with a thickness ranging from 15mm to 20mm, and the mounting hole 8 has a diameter of 10mm to 12mm; the placement plate 7 is made of PVC material with a thickness of 8mm to 10mm and an area ranging from 200mm×200mm to 300mm×300mm; the first electric actuator 32 is model DTZ1000 with a rated voltage of 24V. The first electric actuator is a DC type with a rated thrust range of 500N-1000N and a stroke range of 100mm-150mm; the second electric actuator, model 52, is a DTZ1500 with a rated voltage of 24V DC, a rated thrust range of 1000N-1500N, and a stroke range of 150mm-200mm; the drive motor, model 61, is a 57BLDC brushless DC motor with a rated voltage of 24V DC, a rated power range of 100W-200W, and a rated speed range of 1000r / min-2000r / min; the electronic component circuit system uses 24V... Powered by a DC switching power supply with a current range of 5A-10A, the first electric push rod 32, the second electric push rod 52, and the drive motor 61 are connected to the controller via relays. The controller outputs control signals to the relays, which control the power on and off of each actuator to achieve the desired action. The controller is an STM32F103RCT6 microcontroller, which is installed inside the mounting plate 2 on one side of the frame 4. It is connected to the relays of the first electric push rod 32, the second electric push rod 52, and the drive motor 61, as well as the external power supply, via wires. The control principle is as follows: the controller receives external operation commands such as button inputs, performs internal program calculations (the internal program uses the integrated program of a conventional PLC controller, which is a current technology), and outputs corresponding control signals to control the relays to engage or disengage. This, in turn, controls the extension and retraction of the first electric push rod 32 to clamp and release the workpiece, the extension and retraction of the second electric push rod 52 to lift and lower the screwing module 6, and the start and stop of the drive motor 61 to tighten the workpiece.
