Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic assembly installation, and in particular to a method and system for assembling a hydraulic assembly without peeling glue for enhancing sealing performance. Background Art

[0002] In the field of hydraulic equipment manufacturing, the sealing performance of the hydraulic assembly is directly related to the reliability and service life of the equipment. There are many technical bottlenecks in the traditional hydraulic pipeline assembly process: First, in the seal installation link, the conventional knocking assembly process has significant defects. When the operator uses a rigid tool such as a copper rod to directly knock on the cylinder body or the sealing flange, it is very easy to cause micro-deformation of the seal due to the uneven distribution of the impact force. This rough operation method will not only directly cause physical damage such as lip flanging, indentations or microcracks on key sealing components such as O-rings and combined gaskets, but will also form a stress concentration area on the sealing interface, accelerate the fatigue failure of the seal, and lead to a significant increase in the risk of medium leakage.

DETAILED DESCRIPTION

[0033] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, in which the electrical components are electrically connected in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0034] Example

[0035] See also Figure 1-9 The hydraulic industry is currently developing innovative technical solutions to improve sealing performance and simplify assembly processes. However, the following prominent issues still exist in the splicing and knocking installation of hydraulic equipment, which directly threaten sealing performance and system reliability. Particularly critical is that during the knocking installation process, if tools such as copper rods are used to knock excessively hard on the cylinder body or sealing flange, it will cause deformation of the parts, thereby damaging the integrity of key seals such as O-rings and combination gaskets. This rough operation may not only cause direct damage such as flanging, indentation, or microcracks on the sealing lip, leading to medium leakage, but also accelerate seal fatigue failure due to stress concentration, posing a safety hazard.

[0036] Therefore, this application protects a method and system for assembling a hydraulic assembly without peeling glue to enhance sealing performance. Conventional hydraulic pipeline assembly requires peeling off the outer rubber layer of the hose to expose the steel wire reinforcement layer. This process is prone to rusting the steel wire and damaging the rubber layer during crimping. Conventional hydraulic pipeline assembly requires peeling off the outer rubber layer of the hose to expose the steel wire reinforcement layer. This process is prone to rusting the steel wire and damaging the rubber layer during crimping, affecting sealing performance and service life. This system adopts a peeling-free glue technology. Through a specially designed arc-shaped convex block 108 and a groove block structure, it directly acts on the steel wire layer to achieve precise crimping, avoiding the risk of rust. At the same time, the outer rubber layer is completely retained to prevent premature failure caused by excessive crimping. The electromagnetic transporter is installed on the processing bracket 2. The electromagnetic transporter is used to magnetically adsorb and transport the hydraulic assembly parts on the raw material feeding conveyor. The electromagnetic transporter uses the principle of magnetic adsorption to non-destructively grab precision parts such as hydraulic valve blocks and cylinder bodies.Compared with traditional mechanical grippers, this technology eliminates the problem of part deformation caused by excessive clamping force, and at the same time cooperates with the XYZ three-axis movement of the vertical and horizontal screw module 101 to achieve micron-level positioning accuracy. The hydraulic outer tube is magnetically transported to the clamping system, and the hydraulic outer tube is squeezed and fixed by the clamping system. The horizontal drive motor 307 is operated to drive the horizontal gear 308 on the driving end of the horizontal drive motor 307 to rotate, and the horizontal gear 308 drives the horizontal rack 306 engaged with the gear, and the horizontal rack 306 drives the vertical arc extrusion block 304 on it to perform stable horizontal expansion and contraction, so that the inserted arc extrusion block 109 can be stably expanded and contracted horizontally along the horizontal bearing wheels on the multiple concave bearing blocks 309, thereby The arc extrusion block 304 moves to the top of the clamping arc support block 301, and is operated by a pair of multiple lifting clamping assemblies on the inner side of the lifting and stretching drive box 302. A pair of multiple horizontal stretching electromagnets on the lifting clamping assembly are energized to transmit magnetism to a pair of multiple lifting circular metal blocks respectively. The pair of multiple lifting circular metal blocks through electromagnetic conduction respectively make the lifting circular metal plate and the lifting plug-in magnet on the lifting support limit block to be stably lifted and lowered. The multiple lifting threaded tubes 401 and the lifting threaded rods 402 on the inner side are driven by a pair of multiple lifting support limit blocks, so that the multiple lifting threaded rods 402 are inserted into the inner side of the lifting hole on the circular lifting and stretching block 305, and then the lifting threaded rods 402 are inserted into the inner side of the lifting hole on the circular lifting and stretching block 305. The horizontal telescopic electromagnet is energized, and a pair of multiple horizontal telescopic electromagnets are used to magnetically repel a pair of multiple horizontal telescopic magnets respectively, and a pair of multiple horizontal telescopic magnets are used to drive the plug-in shafts 405 thereon respectively, and the pair of multiple plug-in shafts 405 are used to stably extend and retract horizontally along the inner sides of a pair of multiple horizontal telescopic slots respectively. At the same time, a pair of multiple plug-in shafts 405 respectively drive the multiple L-shaped plug-in rods 404 thereon, so that the multiple L-shaped plug-in rods 404 are movably inserted into the inner sides of the holes on the multiple lifting threaded rods 402 respectively, and the lifting drive motor on the lifting support block is operated to drive the lifting gear set 403 on the driving end of the lifting drive motor respectively, and the lifting gear set 403 drives the multiple lifting threaded tubes 401 inside thereof to rotate, so as to rotate. The lifting threaded rod 402 is stably lifted and lowered along the inner side of the lifting threaded tube 401, so that the locked lifting threaded rod 402 drives the circular lifting and stretching block thereon, so that the lifting threaded rod 402 is stably lifted and lowered along the lifting threaded tube 401, and at the same time, the vertical arc extrusion block 304 thereon is driven by the circular lifting and stretching block 305, and at the same time, the hydraulic outer tube is squeezed and fixed in the vertical direction through the stable lifting of the vertical arc extrusion block 304, and a three-dimensional clamping force field is formed through the coordinated action of the vertical arc extrusion block 304 and the horizontal support wheel 310, thereby ensuring that the hydraulic pipeline is uniformly stressed in all directions.At the same time, the spiral transmission mechanism of the lifting threaded tube 401 and the threaded rod can automatically compensate for the clamping gap according to the tolerance of the parts, ensuring that the coaxiality of the hydraulic pipeline and the flange is ≤0.02mm, which far exceeds the industry standard requirements and significantly improves the sealing performance and stability of the hydraulic assembly. The spiral transmission mechanism of the lifting threaded tube 401 and the threaded rod can automatically compensate for the clamping gap according to the tolerance of the parts, ensuring that the coaxiality of the hydraulic pipeline and the flange is ≤0.02mm, which far exceeds the industry standard requirements. The knocking component adopts a spring buffer structure and monitors the knocking force in real time through a circular pressure sensor. When the T-shaped knocking rod 202 contacts the sealing flange, the magnetic repulsion between the knocking ring electromagnet and the magnet can accurately control the impact energy, avoiding problems such as sealing lip flanging and indentation caused by traditional copper rod knocking, and significantly reducing the risk of stress concentration.

[0037] Furthermore, through the operation of a pair of multiple installation vertical and horizontal screw modules 101, the installation vertical and horizontal screw modules 101 adopt a double-lead ball screw structure, the horizontal module realizes X-axis coarse positioning (positioning accuracy ±0.02mm), and the longitudinal module completes Z-axis fine positioning (repeat positioning accuracy ±0.005mm). The two modules realize motion superposition through the PLC closed-loop control system, ensuring that the spatial position accuracy of the transport and installation hydraulic push rod group 102 is ≤0.05mm, driving the pair of multiple transport and installation hydraulic push rod groups 102 thereon to perform vertical and horizontal movement, and through the extension and contraction of a pair of multiple transport and installation hydraulic push rods, driving the pair of multiple concave transport limit blocks 103 thereon to perform relative extension and contraction. The transport and installation hydraulic push rod group 102 has a built-in pressure sensor and a proportional servo valve, which can achieve a thrust range adjustment of 0-5000N. Through the PID control algorithm, the friction and inertia forces during the extension and retraction of the push rod are compensated in real time to ensure that the displacement accuracy of the concave transport limit block 103 reaches the micron level. The concave transport limit block 103 drives the transport limit shaft 104 inside it and the transport limit block 105 thereon, and the transport limit block 105 drives the circular arc groove block 107 thereon, and the circular arc groove block 107 drives the circular arc limit shaft 110 inside it and the circular arc convex block 108, and the circular arc convex block 108 drives the circular arc extrusion block 109 thereon, so that the sealing components are relatively squeezed and fixed by a pair of multiple relatively telescopic circular arc extrusion blocks 109, and the circular arc extrusion block 109 is knocked by the knocking component, so that the vibration of the circular arc extrusion block 109 due to the knocking is transmitted to the transport limit block 105, so that the transport limit block 105 moves along the pair of multiple concave transport The transport limit shaft 104 inside the limit block 103 is stably extended and retracted, and at the same time, the transport limit block 105 drives a pair of multiple transport limit set springs 106 thereon, thereby converting the vibration into elastic deformation of the transport limit set spring 106, thereby achieving a buffering effect. At the same time, a pair of multiple angle ring electromagnets 113 inside the arc-shaped groove block 107 are energized, and the current direction and current size on the pair of multiple angle ring electromagnets 113 are changed, thereby changing the magnetic adsorption or magnetic repulsion effect of the pair of multiple angle ring electromagnets 113, so that a pair of multiple arc-shaped convex blocks 108 are stably rotated along a pair of multiple arc limit shafts 110, thereby changing a pair of multiple arc extrusion blocks 109 and the component extrusion angle for adjustment, and the angle ring electromagnet 113 realizes magnetic attraction gradient control by changing the current size (0-5A).When the tapping point needs to be adjusted, the electromagnet adjusts the magnetic attraction in 0.1A steps to drive the arc-shaped convex block 108 to rotate along the arc limit axis 110 (maximum rotation angle ±30°). Through the specially designed arc-shaped convex block 108 and groove block structure, it directly acts on the steel wire layer to achieve precise buckling without peeling off the outer rubber layer, thereby completely avoiding the risk of steel wire rust. At the same time, the outer rubber layer is completely retained, effectively preventing early failure caused by excessive buckling, significantly improving the sealing and durability of the hydraulic assembly, and realizing the circumferential position adjustment of the tapping point, thereby changing the tapping point of the tapping component. Rotational adjustment is achieved by energizing the knocking ring electromagnet on the inside of the knocking shaft tube 201, magnetically adsorbing the knocking ring magnet 204 through the knocking ring electromagnet, driving the knocking shaft tube 201 on it through the knocking ring magnet 204, driving the T-shaped knocking rod 202 on it through the knocking shaft tube 201, and contacting the knocking sleeve tube 206 on the T-shaped knocking rod 202 with the annular pressure sensor on the knocking shaft tube 201, thereby measuring the knocking force. The knocking shaft tube 201 has a built-in annular pressure sensor (range 0-1000N, accuracy ±1N) and a laser displacement sensor (resolution 0.1μm). When the T-shaped knocking rod 202 contacts the sealing flange, the system adjusts the knocking force in real time through sensor feedback to ensure that the four-point knocking force error is ≤2%. At the same time, the T-shaped knocking rod 202 squeezes and contracts the knocking set spring 203 on it to a certain position, so that after power is cut off, the deformed knocking set spring 203 drives the T-shaped knocking rod 202 on it, so that the parts are knocked by two pairs of T-shaped knocking rods 202 with consistent knocking force. When traditional equipment knocks on the sealing flange, it may cause problems such as sealing lip flanging and indentation due to improper control of impact energy, thereby affecting the sealing effect; this system adopts a spring buffer structure and annular pressure sensor, and can accurately control the impact energy by knocking the magnetic repulsion between the annular electromagnet 113 and the magnet, avoiding the problems of sealing lip flanging and indentation caused by traditional copper rod knocking, significantly reducing the risk of stress concentration, and ensuring the flatness and sealing performance of the sealing flange.

[0038] In summary, it can be seen that the electromagnetic carrier is used in conjunction with the double-lead ball screw module to achieve XYZ three-axis micron-level positioning (X axis ± 0.02mm / Z axis ± 0.005mm), combined with the hydraulic push rod group PID force control technology to ensure that the arc extrusion block 109 is accurately clamped with an adjustable pressure of 0-5000N; the innovative peeling-free structure directly acts on the steel wire layer through the magnetic adaptive design of the arc-shaped convex block 108 and the groove block, which not only avoids damage to the outer rubber layer but also prevents rust. In conjunction with the four-point synchronous knocking mechanism, the spring buffer system is used to control the vibration acceleration below 0.5g, and at the same time, the angle ring electromagnet 113 (0-5A current adjustment) is used to achieve ±3 The 0° tapping point rotation, combined with the circular pressure sensor (±1N accuracy) and the laser displacement sensor (0.1μm resolution), forms a double closed-loop control to ensure that the four-point tapping force error is ≤2%; its three-dimensional clamping force field works together through the vertical arc extrusion block 304 and the horizontal support wheel 310, and cooperates with the spiral transmission mechanism to automatically compensate for the tolerance (coaxiality ≤0.02mm), so that the contact stress uniformity of the seal reaches more than 95%, which is 58% lower than the compression deformation rate of the O-ring in the traditional process, and the leakage rate of the combined sealing gasket is reduced from 0.2% to 0.03%. The overall equipment efficiency (OEE) reaches 85%, realizing full-process quality control from precise positioning, adaptive clamping to intelligent tapping.
