Description

TECHNICAL FIELD

[0001] The application relates to the technical field of integrated joint processing, in particular to an integrated joint rapid buckling connection assembly method and system with improved efficiency. BACKGROUND

[0002] An integrated joint is a very common connection structure in modern electrical, mechanical and hydraulic systems. The integrated joint is usually composed of a center pipe and two end joints. The joint needs to be buckled and connected when matched with the pipe to ensure the connection stability of the joint and the pipe.

[0003] At present, the rapid buckling connection of the integrated joint mainly relies on a buckling machine. The buckling machine is usually composed of a buckling mechanism, a hydraulic system and an electrical control system. The electrical control system controls the hydraulic system as a power source to drive the buckling mechanism to punch the pipe wall of the joint.

[0004] However, in the buckling process of the integrated joint at the present stage, the joint needs to be manually sleeved on the pipe, and the joint and the pipe need to be inserted into the buckling machine. The method has the following disadvantages: low efficiency: manual sleeving, carrying and positioning steps are complicated, which becomes the bottleneck of production line speed-up; poor consistency: manual operation easily introduces pipe clamp and pipe alignment deviation, leading to uneven buckling or sealing failure; low automation: relying on manual intervention, difficult to integrate into high-efficiency continuous production line, and increasing labor cost and safety risk.

[0005] Based on the above-mentioned shortcomings, the continuous fiber reinforced polyethylene composite pipe hot pre-buckling joint and its method disclosed in the publication No. CN119036871B can place one end of the composite pipe to be buckled on the inner side of the movable link, at the same time, the end face of the composite pipe is in contact with the rectangular blocking rod, then the rotating ring is rotated, the clamping plate clamps and limits the composite pipe through the rotation of the rotating ring, so as to realize the accuracy of the butt joint of the composite pipe and the professional joint, and the sleeving position of the composite pipe and the professional joint is just below the buckling plate. After limiting the composite pipe and the joint, the bidirectional screw rod is rotated, the two limiting sliders on the bidirectional screw rod move towards each other through the rotation of the bidirectional screw rod, so as to know the coincidence length of one end of the composite pipe and the joint, and accurately adjust the connection length of the composite pipe and the joint. Although the positioning and length adjustment in the buckling process are optimized, the fundamental limitation of "manual pre-assembly" cannot be broken, and the increase of the structural complexity may even further reduce the operation convenience. Therefore, there is an urgent need for a buckling connection system that can completely eliminate the manual pre-assembly link and realize full-process automation to solve the core contradiction of efficiency, accuracy and automation integration.

The drive roller shaft 25 installed on the legs 24 is connected to the reducer 23 through belt transmission to form a torque transmission connection. The conveyor belt 26 sleeved on the drive roller shaft 25 is made of polyurethane and has anti-slip texture.

[0055] According to the instruction manual Figures 1-9 It can be seen that the linear conveyor 2 is driven by a stepper motor 21. The output shaft of the stepper motor 21 is connected to the input end of the gearbox through a coupling. The output end of the gearbox is rigidly connected to the drive shaft 27 through multi-stage gear transmission to form a power transmission chain.

[0056] A pair of alignment guides 5 are provided on both sides of the starting end of the linear conveyor 2. The V-shaped adjustable structure of the guide can be adjusted by the existing screw mechanism. Wear-resistant plastic sliders are embedded on the inner guide rail surface. Several processing stations 22 are evenly arranged on the linear conveyor 2. The processing stations 22 are matched with the diameter of the installation pipe to facilitate the positioning of the installation pipe. The inner side of the guide and the outer end of the installation pipe form a guiding fit to ensure that the installation pipe remains centered after entering the processing station 22.

The surface of the rolling assembly 31 is radially arranged with no less than four placement stations 33. The gear structure of the indexing device 32 ensures that during the movement interval of a pair of adjacent processing stations 22, the stepper motor 21 can drive the rolling assembly 31 to rotate by an angle of an adjacent placement station 33, forming an intermittent motion engagement. When the stepper motor 21 stops, it also stops quickly.

[0069] When the system is running, the linear conveyor 2 moves the installation pipe to the machining station 22 under the drive of the stepping motor 21, the V-shaped guide rail of the guide 5 automatically corrects the position of the workpiece, the stepping motor 21 drives the indexer 32 through the driving shaft 27 to rotate, so that the pipe clamp position on the indexing disc 313 is accurately aligned with the conveying belt position, the pneumatic clamping jaw of the dialing assembly 47 grabs the pipe clamp, and then the pipe clamp is sleeved into the end of the installation pipe under the guidance of the conical insert block 474, and the photoelectric sensor 6 detects the position signal to trigger the buckling program: the inner pipe 421 is first lowered to complete the workpiece positioning, and then the outer pipe 425 is pushed forward to drive the buckling piece 45 to be radially compressed through the conical surface engagement, so that the consistency of the pressure connection accuracy is ensured each time, and the whole process is realized through the synchronous mechanical linkage to realize the continuous operation of synchronous feeding, synchronous positioning and synchronous pressure connection, the conical surface engagement mechanism converts the axial movement into uniform radial pressure, and the quick-change structure supports the quick switching production of multiple specifications of products.

9. A method for improving the efficiency of an integrated connector quick-clamping connection assembly, applied to the improved efficiency integrated connector quick-clamping connection assembly system according to any one of claims 1-8, characterized in that, Includes the following steps; Step 1: Installation tube positioning and correction: The installation tube is moved to the starting position via a linear conveyor. The V-shaped guide rail of the alignment guide automatically corrects the position deviation of the installation tube, with a positioning accuracy of ±0.1mm. The conveyor belt steps forward to move the installation tube to the crimping position, and the pressure sensor provides real-time feedback on the positioning status. Step 2: Synchronous feeding of pipe clamps: The stepper motor drives the indexer to rotate synchronously through the flange coupling, and the rolling assembly precisely rotates the station angle; the pipe clamps of the linear feeder fall into the positioning groove of the grooving plate through the baffle interlock control, and the indexing plate and the conveyor belt station achieve axial coaxial alignment. Step 3 Automatic coupling: The pneumatic gripper grabs the coupling and moves it radially along the lever. The tapered guide head is inserted into the end of the installation pipe to form primary positioning. The gripper then fits the coupling into the installation pipe along the tapered surface of the insert block. The two-stage guide system ensures that the coaxiality error is ≤0.05mm. Step 4: Triple mechanical locking: The photoelectric sensor triggers the telescopic cylinder to push the inner tube down, the guide rod compresses the limit spring to generate stroke, the fastening plate guide post is inserted into the installation tube port, and the guide block positioning cone is fitted into the inner hole of the pipe clamp, forming a triple locking in the axial, radial and circumferential directions; Step 5: Pressing and Resetting Step 5.1 In the initial stage, compress the spring to make the conical groove engage with the conical surface of the guide block; Step 5.2 In the final pressing stage, the conical surfaces fully engage, generating a radial force that drives the fasteners to synchronously and centripetally contract and press the pipe clamps together. After step 5.3 is completed, the hydraulic cylinder returns, and the spring releases energy to push the inner and outer tubes to reset and detach from the workpiece; Step 6 Finished Product Stepping Unloading: The conveyor belt steps and moves the crimped components to the unloading station. The indexer rotates synchronously to prepare new pipe clamps. After the pressure sensor confirms that the workpiece has been removed, the system automatically enters the next cycle.
