Description

Technical Field

[0001] This invention relates to the field of metal hose technology, and in particular to an assembly tooling and assembly method for metal hoses with multiple spatial orientations. Background Technology

[0002] Metal flexible hoses are widely used in piping systems in petrochemical, aerospace, shipbuilding, power, and machinery industries due to their excellent flexibility, fatigue resistance, pressure resistance, and displacement compensation capabilities. They are used to absorb vibration, compensate for thermal expansion and contraction, and address installation misalignments. In pipeline layouts, the direction and angle of the metal flexible hose constantly change due to fluid flow, thus placing higher demands on its spatial dimensions, i.e., its form and position dimensions. Metal flexible hoses are used to connect the flanges at both ends of the pipeline, and there is a certain spatial angle between the two flanges (i.e., they are not on the same straight line).

[0003] Currently, traditional flexible metal hoses are typically installed with flanges at both ends using existing universal adjustment fittings. These universal metal hose adjustment fittings are usually fixed-frame connecting flanges, and this assembly method can only provide support or limited fixation in a single direction or angle. In other words, traditional metal hose manufacturing and assembly methods are difficult to meet the spatial angle requirements between the flanges at both ends. Furthermore, when installing the flexible metal hose onto flanges with spatial angles, multiple adjustments by multiple people are required to adapt to multiple spatial angles, resulting in time-consuming, labor-intensive, and costly processes. Summary of the Invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an assembly tooling and assembly method for metal hoses with multiple spatial orientations. It solves the technical problems that traditional metal hose manufacturing and assembly methods are difficult to meet the spatial angle requirements between the flanges at both ends, and that when the metal hose is installed to the flanges at both ends with spatial angles, multiple adjustments by multiple people are required to adapt to multiple spatial angles, resulting in time-consuming, labor-intensive and costly technical problems.

[0018] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] See Figures 1-5 As shown in the embodiment of the present invention, an assembly fixture for a multi-space-oriented metal flexible hose 100 is mainly used for spatial angle positioning and precise attitude adjustment of the corrugated metal flexible hose 100 during the assembly process. It includes a reference mounting component 1 and an adjusting mounting component 2 disposed at both ends of the metal flexible hose 100 to be assembled. The reference mounting component 1 is connected to a flange at one end of the metal flexible hose 100 to fix the first end of the metal flexible hose 100. The adjusting mounting component 2 is connected to a flange at the other end of the metal flexible hose 100 to fix the second end of the metal flexible hose 100. The adjusting mounting component 2 can adjust the height, horizontal rotation angle, and pitch swing angle of the second end of the metal flexible hose 100 to determine the installation position of the flange at the other end of the metal flexible hose 100.

[0020] In this embodiment, an assembly fixture for a multi-space-oriented metal flexible hose 100 is provided, wherein the adjusting mounting component 2 provides three degrees of freedom adjustment: height, horizontal rotation, and pitch. Through the coordinated operation of the adjusting mounting component 2 and the reference mounting component 1, the spatial orientation of both ends of the metal flexible hose 100 can be precisely adjusted and fixed. Because the metal flexible hose 100 is flexible and easily deformable, the relative spatial position requirements of the flanges at both ends must be strictly met during assembly. This solves the problems of traditional methods that rely on multiple people lifting and repeated trial assembly, resulting in low efficiency and difficulty in ensuring accuracy. Through the coordinated cooperation of the reference mounting component 1 and the adjusting mounting component 2, the precise alignment, stable support, and final fixation of the flanges at both ends of the metal flexible hose 100 in spatial angle are achieved. This invention, through rigid adjustable support and a graduated angle indicating mechanism, allows a single person to efficiently complete the setting and locking of complex spatial angles, meeting the angle requirements for assembling the various components of the metal flexible hose 100, significantly improving assembly accuracy and work efficiency, and avoiding additional stress, leakage risks, and workpiece damage caused by misalignment.

[0021] This invention primarily addresses the problems of assembly difficulties, low efficiency, and difficulty in ensuring precision when assembling corrugated metal flexible hoses 100 due to their flexibility and easy deformation, as well as the strict requirements for the spatial angles of the flanges at both ends. Traditional assembly methods typically rely on multiple people lifting the hose, repeated trial assembly, and visual alignment, which is not only labor-intensive and time-consuming but also makes it difficult to ensure coaxiality, parallelism, and bolt hole alignment, easily introducing additional stress or causing leakage. This fixture provides a rigid, adjustable, modular support system with graduated indicators, enabling a single person to efficiently and accurately complete the setting and locking of complex spatial angles.

[0022] Furthermore, the adjusting mounting component 2 includes a fixed base 21 and a height adjusting structure 22. The height adjusting structure 22 is fixedly installed above the fixed base 21. The height adjusting structure 22 includes a cylinder 221 fixedly installed on the fixed base 21. A vertical guide groove 222 is provided on the outer wall of the cylinder 221. An adjusting ring 223 is fitted on the outer wall of the cylinder 221. A force application hole 224 corresponding to the vertical guide groove 222 is provided on the outer peripheral side wall of the adjusting ring 223. A positioning key is provided on the inner wall of the adjusting ring 223 protruding towards the vertical guide groove 222. The adjusting ring 223 can move up and down along the axial direction of the cylinder 221. An annular pressure cap 225 is provided on the top of the adjusting ring 223. The annular pressure cap 225 is fixed in position by locking screws. Four support legs 212 are vertically fixed to the mounting base 211. The outer wall of the cylinder 221 is machined with a vertical guide groove 222 (16mm wide, 60mm deep) to provide a precise linear guide for height adjustment. The adjusting ring 223 has four evenly distributed Φ18mm force holes 224 around its circumference. During assembly, inserting a pry bar into any of the force holes 224 applies torque, driving the height adjusting ring 223 and all its components to move up and down along the vertical guide groove 222. This allows the entire upper mechanism (annular cover 225 and horizontal rotating structure 23) to rise and fall in the Z-axis direction, with an adjustment range of ±60mm. After adjustment, the annular cover 225 is tightened with screws to prevent slippage or loosening.

[0023] Furthermore, the adjusting mounting component 2 also includes a horizontal rotating structure 23. The horizontal rotating structure 23 has a rotating base 231 fixedly mounted above the height adjusting structure 22 and a rotating disk 232 that rotates axially relative to the rotating base 231. The rotating base 231 includes a sleeve 2311, with an annular wall 2312 protruding radially outward from the bottom of the sleeve 2311. An annular cap 225 fixes the annular wall 2312 to the adjusting ring 223. The sleeve 2311 is fitted onto the outer wall of the cylinder 221. A guide key 2313 is detachably connected to the inner wall of the sleeve 2311. The guide key 2313 protrudes inward relative to the inner wall of the cylinder 221 and is slidably mounted in the vertical guide groove 222. A rotating base plate 2314 is fixedly mounted on the top of the sleeve 2311. The rotating disk 232 is mounted on the rotating base plate 2314 via the positioning disk 234, and the rotating disk 232 and the rotating base plate 2314 are rotatably connected. This rotatable connection is achieved through bearings or low-friction bushings. The guide key 2313 on the inner wall of the sleeve 2311 engages with the vertical guide groove 222 of the height-adjustable cylinder 221, ensuring that it can only move up and down, not rotate. The rotating base plate 2314 is fixed to the top of the sleeve 2311.

[0024] During horizontal rotation adjustment, a pre-set fixed reference mark (or laser marking) on ​​the assembly platform 200 is used as a reference. The operator rotates the rotary disk 232 to align the engraved line on its upper surface with the external reference mark, thus achieving a rough alignment of the rotation angle around the Z-axis. For scenarios requiring higher precision, fine-tuning and locking can be performed using measuring tools. This design avoids the need for complex circumferential scales, simplifying the structure and reducing costs.

[0025] Furthermore, the top end face of the rotating disk 232 is provided with a scale line in the circumferential direction. (That is, the rotating disk 232 is marked with a single scale line on the upper surface, which is not shown in the figure).

[0026] Furthermore, the adjusting mounting component 2 also includes a pitch-swing structure 24. The pitch-swing structure 24 includes two opposing upright plates 241 fixedly mounted on the top end face of the rotating disk 232 and a mounting flange 242 disposed between the two upright plates 241. An arc-shaped groove 243 is provided on the side wall of the upright plate 241, and the mounting flange 242 is mounted between the two upright plates 241 via a rotating shaft. Locking screw holes are provided on opposite sides of the mounting flange 242 near the upright plate 241. When the mounting flange 242 is rotated along the rotating shaft to determine its position, it is locked in the locking screw holes by locking screws passing through the arc-shaped groove 243. A through hole 2421 is provided on the end face of the mounting flange 242, and a connecting hole 2422 is provided on the outer periphery of the through hole 2421 of the mounting flange 242. The connecting hole 2422 is used to install the metal flexible hose 100.

[0027] Furthermore, arc-shaped scale plates 2431 are provided on both sides of the arc-shaped groove 243. (The arc-shaped scale plates 2431 are ±45° scale plates and graded lines marked on the side wall of the vertical plate 241).

[0028] When adjusting the pitch, observe the arc-shaped dial 2431 on the upright plate 241, and directly push or use tools to fine-tune the mounting flange 242 until its reference line (or by observing the hose posture) aligns with the target angle mark on the dial, for example, +15° or -10°. After adjustment, securely fix the mounting flange 242 by tightening the locking screws on the upright plate 241. The mounting flange 242 is ultimately used to clamp the flange at the other end of the metal hose 100.

[0029] Furthermore, the fixed base 21 includes a mounting base 211 and four support legs 212. Support legs 212 are fixedly installed at the four corners of the bottom end face of the mounting base 211, and a cylinder 221 is fixedly installed on the top end face of the mounting base 211.

[0030] Furthermore, the reference mounting component 1 includes a reference base 11, a reference upright plate 12, a positioning flange 13, and four reference legs 14. Reference legs 14 are fixedly installed at the four corners of the bottom end face of the reference base 11, and two symmetrically arranged reference upright plates 12 are fixedly installed on the top end face of the reference base 11. Multiple arc-shaped guide grooves 121 are formed on the reference upright plates 121, and arc-shaped scale plates 122 are formed on the arc-shaped guide grooves 121. The positioning flange 13 is mounted on the reference upright plate 12 via a rotating shaft and swings relative to the reference upright plate 12. After determining the swing angle, the positioning flange 13 is locked onto the reference upright plate 12 by positioning screws. The reference mounting component 1 provides a single degree of freedom for pitch swing. By adjusting the mounting component and the reference mounting component 1 in tandem, the spatial orientation of both ends of the corrugated metal flexible hose 100 can be precisely adjusted and fixed.

[0031] In this embodiment, the reference legs 14 are all magnetic base type I seats, which are used to firmly attach the entire tooling to the steel assembly platform 200 by magnetic force, ensuring that the reference surface of the tooling is horizontal and does not shift during the entire assembly process. The reference base 11 is made of Q235B steel plate with a thickness of 20mm, which has sufficient rigidity and stability. Its bottom is connected to the magnetic base by hexagonal screws, and its top is fixed to the reference plate 12 by screws, forming the base of the tooling. The core function of the reference plate 12 is to support and guide the swing trajectory of the positioning flange 13. It is installed between the two reference plates 12 by a rotating shaft. It can swing back and forth within a certain angle range (e.g., ±30°) along the arc-shaped guide groove 121 on the reference plate 12. The positioning flange 13 is used to clamp and fix the flange at one end of the metal hose 100. By adjusting its swing angle, it can be initially adapted to the spatial angle requirements of that end of the hose, and is locked by screws.

[0032] Furthermore, the included angle between the reference mounting component 1 and the adjusting mounting component 2 is 0°-180°. In this embodiment, the included angle between the reference mounting component 1 and the adjusting mounting component 2 is 90°. The installation space is limited at this angle, and this solution can greatly improve the installation efficiency before delivery.

[0033] An assembly method for a metal flexible hose 100, the assembly method being based on an assembly fixture for a multi-space-direction metal flexible hose 100, the assembly method comprising the following steps: S2. Fine-tune the positioning flange 13 on the reference mounting part 1 to accurately position the bolt holes of the flange at one end of the metal hose 100. S3. Pre-fix the flange at the other end of the metal hose 100 to the mounting flange 242 of the adjusting mounting component 2; S4. After determining the metal hose 100, adjust the height, horizontal rotation angle and front and back swing angle of the mounting part 2 until the spatial posture of the hose fully meets the design requirements. S5. Lock and fix the height, rotation angle, and swing angle; S6. Tighten the locking screws of both flanges completely, and then spot weld the metal hose 100 to the flanges at both ends to complete the assembly of the entire metal hose 100.

[0034] Preparation and initial fixing: Attach the reference mounting component 1 and the assembly fixture to their predetermined positions on the assembly platform 200. Fix one flange of the metal hose 100 to the positioning flange 13 of the reference mounting component 1, and fix the other flange to the mounting flange 242 of the assembly fixture.

[0035] Three-degree-of-freedom fine-tuning: A single operator can adjust the settings sequentially. That is, S3 includes: Step S31 (Height): Adjust the height adjustment ring 223 using the pry bar to bring the other end of the hose to the target height.

[0036] Step S32 (Horizontal Rotation): Rotate the rotating disk 232 and align it with the reference mark on the platform to complete the angle adjustment in the horizontal plane.

[0037] Step S33 (Pitch): Refer to the clearly readable dial on the vertical plate 241 and adjust the pitch angle of the mounting flange 242 to the required value.

[0038] These three steps can be performed alternately and coupled together to compensate for each other, until the spatial attitude of the hose fully meets the design requirements.

[0039] Final alignment and locking: After the assembly fixture has been adjusted and initially locked, the swing angle of the positioning flange 13 on the reference mounting part 1 is finely adjusted to ensure precise alignment of the bolt holes on the flanges at both ends of the hose. Then, the locking screws on both flanges are fully tightened to complete the assembly of the entire metal hose 100.

[0040] As can be seen from the above, the core beneficial effects of this invention are as follows: High precision and high reliability: The rigid structure and graduated precision guide mechanism provide stable and reliable support for the flexible and changeable metal hose 100, ensuring the parallelism, coaxiality and hole alignment of the flanges at both ends, fundamentally improving the sealing quality and connection reliability.

[0041] High efficiency and low effort: The complex spatial adjustments that traditionally required multiple people to work together and make repeated trial and error are transformed into standardized operations that can be completed by a single person step by step. Clear scale indications (especially the graded lines on the pitch dial) and mechanical adjustment mechanisms make the adjustment process fast, intuitive, and labor-saving, significantly shortening the assembly cycle.

[0042] High adaptability: The three-degree-of-freedom adjustment mechanism provides ample adjustment capability, capable of meeting the angle requirements of assembling various components of the metal hose 100 into the metal hose 100. It adapts to the assembly needs of various spatial angles and hose models.

[0043] Alternatively, in other embodiments, the magnetic base can be replaced with a vacuum suction cup or mechanical pressure plate, depending on the platform material, for fixing.

[0044] Optionally, the driving method of the height adjustment ring 223 can also be changed to a lead screw and nut mechanism or a gear and rack mechanism to achieve more effortless or more precise fine adjustment.

[0045] Optionally, the rotary disk 232 can be upgraded to a turntable structure with a precision scale and a locking handle to meet the special requirements of extremely high precision in horizontal rotation angle.

[0046] Optionally, the arc-shaped grooves 243 on the upright plate 241 and the reference upright plate 12 can be designed with T-slots and locked with T-bolts to provide stronger shear resistance and locking stability.

[0047] Please see Figure 6 In existing technologies, the common assembly method for metal flexible hoses 100 typically employs a combination of general-purpose clamps or a simple support frame. This method mainly includes a fixed platform with two independent V-blocks or simple flange clamps on it, used to support the flanges at both ends of the metal flexible hose 100. During assembly, two or more operators must manually lift the metal flexible hose 100, adjust its spatial posture, and attempt to align the flanges at both ends with the flanges of the connecting pipe. During this process, due to the high flexibility and easy deformation of the metal flexible hose 100, and the lack of a reliable, multi-degree-of-freedom adjustment mechanism with graduated indicators, operators must repeatedly attempt, visually observe, and manually fine-tune. This is not only time-consuming and labor-intensive, but also makes it difficult to accurately guarantee the parallelism, coaxiality, and bolt hole alignment accuracy of the flanges at both ends. The assembly quality is highly dependent on the operator's experience, and misalignment can easily introduce additional stress into the hose, posing a risk of leakage during long-term operation. Furthermore, it cannot achieve efficient and repeatable assembly in complex spatial angles.
