Description

Technical Field

[0001] The invention relates to the technical field of semi-automatic assembly platforms, in particular to a high-precision constant-force spring support and hanger semi-automatic assembly platform. Background Art

[0002] High-precision constant-force spring supports and hangers are devices used to support and fix pipeline systems. They are designed based on the principle of moment balance. Through the combination of lever mechanisms and springs, the supports and hangers can maintain a balance between load torque and spring torque when the pipeline is displaced. Within the entire allowable load displacement range, the support force change rate of the supports and hangers is extremely small (usually less than 5%), thereby achieving a nearly constant support force.

[0003] The existing constant force spring hanger is mainly composed of a main spring and auxiliary springs on both sides of the main spring. Its working principle is to suspend and support pipelines and equipment through the elastic force generated by the main spring and auxiliary spring. Since the support force of the hanger is completely dependent on the elastic force of the spring, it is necessary to adapt constant force spring hangers of different specifications according to the scale of the pipeline and equipment. The larger the equipment, the larger the specifications of the hanger and its internal main spring and auxiliary spring.

[0004] During the assembly process, the auxiliary springs on both sides need to be installed inside the shell first, and the main springs need to be assembled when the auxiliary springs are in a compressed state, so as to ensure that the auxiliary springs are always in a compressed pre-tightened state after the main springs are assembled. However, the current assembly of auxiliary springs usually relies on manual compression with a simple hydraulic mechanism. This method has obvious defects: first, it is difficult to ensure that the tension of the auxiliary springs on both sides is completely consistent, resulting in insufficient assembly accuracy; second, this simple hydraulic mechanism is only suitable for auxiliary springs with smaller specifications. When the specifications of the constant force spring support hanger are larger, the tension and accuracy of the ordinary hydraulic mechanism cannot meet the assembly requirements; during the assembly process of the constant force spring support hanger, if the tension of the auxiliary springs on both sides is not completely consistent, the support hanger will have an unbalanced force problem in the initial assembly state. This imbalance will cause the main spring to be subjected to uneven pre-tightening force during assembly, thereby affecting the mechanical properties and stability of the entire support hanger. In actual operation, the support hanger is prone to tilting, shaking or local stress concentration, resulting in uneven force on the pipeline system, increasing the risk of pipeline deformation or damage, and ultimately reducing the service life and reliability of the support hanger, and even causing safety accidents;

[0005] In order to solve the above problems, the prior art provides some solutions, such as the high-precision constant force spring support and hanger semi-automatic assembly platform and assembly method with publication number: CN117381359B, whose working principle includes the following steps: hoisting the shell to the center of the assembly platform and positioning it, installing the auxiliary springs on both sides, starting the screw drive mechanism of the auxiliary spring compression device, pushing the hydraulic cylinder and the sliding carrier plate to move, so that the threaded sleeve at the front end of the pull rod contacts the screw on the auxiliary spring mounting plate. The U-shaped bracket is connected to the limit groove of the pull rod through the limit cylinder of the limit bracket, the screwing motor is started to drive the pull rod and the threaded sleeve to rotate, the threaded connection between the threaded sleeve and the screw is completed, the limit bracket is unlocked, the hollow sleeve piston rod of the hydraulic cylinder is started, the pull rod and the threaded sleeve are driven to move in the opposite direction, the auxiliary spring is compressed and a uniform tension is provided, the main spring is sent into the housing for assembly through the sliding cylinder, the tension of the hydraulic cylinder is released, the elastic force of the auxiliary spring is released and abuts against the main spring, and finally, the screwing and disengagement operations of the threaded sleeve are repeated to complete the assembly and reset the sliding carrier. However, although this assembly method realizes the assembly of the auxiliary spring and the main spring through mechanical devices and hydraulic systems, it has some shortcomings: first, it relies on the coordinated operation of the hydraulic cylinder and the screw drive mechanism, and has extremely high requirements on the accuracy and synchronization of the equipment. Once a deviation occurs, the tension of the auxiliary spring is uneven, which affects the overall performance of the support and hanger; second, multiple drive sources are used in the assembly process, and different drive devices need to be started and switched multiple times, which is complicated to operate and inefficient; and the use of the hydraulic system increases the equipment cost and maintenance difficulty.

[0006] Therefore, a semi-automatic assembly platform for high-precision constant-force spring supports and hangers is proposed. Summary of the invention

[0007] The purpose of the present invention is to provide a high-precision constant-force spring support and hanger semi-automatic assembly platform. The existing assembly platform relies on the coordinated operation of the hydraulic cylinder and the screw drive mechanism, and has extremely high requirements on the equipment accuracy and synchronization. Once deviation occurs, it will lead to uneven tension of the auxiliary springs, affecting the overall performance of the support and hanger. The present invention utilizes the movement of the rotating component to complete the synchronous compression operation of two groups of auxiliary springs. This function does not require an additional driving source, and can effectively control the compression force of the auxiliary springs during the compression process to avoid excessive compression of the auxiliary springs.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A high-precision constant-force spring support and hanger semi-automatic assembly platform, comprising a workbench, a shell arranged on the workbench, two groups of brackets arranged in the shell, an auxiliary spring arranged between the bracket and the inner wall of the shell, and a main spring arranged in the middle of the shell, and also comprising a rotating assembly arranged on the workbench, the rotating assembly is arranged directly below the main spring, two groups of moving rods are also arranged on the rotating assembly, the moving rods are provided with clamping rods, the clamping rods are clamped on the end surface of the bracket, and a driving member is also arranged on the rotating assembly, the driving member drives the rotating assembly to rotate clockwise, and when the rotating assembly rotates and drives the two groups of moving rods to move the same distance to both sides, the clamping rods thereon compress the two groups of auxiliary springs;

[0010] It can be seen that in the prior art, there are many problems with the method of relying on the coordinated operation of the hydraulic cylinder and the screw drive mechanism to compress the auxiliary spring to install the main spring: on the one hand, this method has extremely high requirements on the accuracy and synchronization of the equipment. Once deviation occurs, it will cause uneven tension of the auxiliary spring. On the other hand, the hydraulic cylinder is easily affected by factors such as pressure fluctuations in the hydraulic system and oil contamination during movement, resulting in a decrease in movement accuracy, and then making the tension of the auxiliary springs on both sides not completely consistent.

[0011] In view of the above problems, the present invention proposes an improved solution, which is to set a rotating assembly, and use its rotation to drive two groups of clamping rods to compress the two groups of auxiliary springs to both sides. During the compression process, the rotating assembly can control the compression force, thereby effectively preventing the auxiliary springs from being over-compressed and protecting the structural integrity of the auxiliary springs. This design not only improves stability, but also reduces the drive source and assembly steps. It is simple to operate and improves the overall installation efficiency and reliability.

[0012] Preferably, the bracket includes a rotating rod, a support rod and a baffle, the rotating rod is provided with two groups and is rotatably connected in the shell, the support rod is arranged on the rotating rod, the baffle is arranged on the support rod, and the two groups of auxiliary springs are arranged between the baffle and the inner wall of the shell.

The two work together, which can help the main spring share part of the load and ensure that the support bracket maintains a stable supporting force under different working conditions.

[0013] Preferably, the rotating assembly includes a rotating shaft, a rotating rod and a movable groove. The rotating shaft is arranged on the side wall of the workbench and is directly below the main spring. The rotating rod is arranged on the rotating shaft. The movable groove is opened at both ends of the rotating rod. The rotating shaft is located in the middle of the rotating rod. When the rotating shaft rotates, it drives the rotating rod to rotate.

[0015] Preferably, two groups of limit grooves are provided on the side walls of the workbench corresponding to the rotating shaft, and the two groups of limit grooves correspond to the telescopic rods. Limit blocks are arranged on the limit grooves, and the limit blocks are connected to the telescopic rods. The ends of the limit grooves are located within the perpendicular bisector of the auxiliary springs. The limit grooves limit the moving distance of the telescopic rods to avoid excessive compression of the auxiliary springs.

[0016] Preferably, the driving member includes a base and a motor, the base is arranged on the side wall of the workbench corresponding to the rotating rod, the motor is arranged on the base, the output shaft of the motor is arranged on the rotating shaft, and the motor is used to drive the rotating rod on the rotating shaft to rotate.

[0017] Preferably, the clamping rod includes a connecting rod, a clamping block, a hinged rod and a torsion spring, the connecting rod is arranged on the fixed rod, the clamping block is arranged at the end of the connecting rod, the hinged rod is rotatably connected to the clamping block via the torsion spring, the clamping block is in contact with the side wall of the baffle, the clamping rod can be automatically clamped on the support rod by thrust, the central axis of the connecting rod is parallel to the central axis of the rotating rod, and the connecting rod and the rotating rod are parallel to ensure that the connecting rod is not hindered by the rotating rod when moving into the inside of the shell.

[0018] Preferably, two groups of ratchets are also provided on the fixed rod, and the two groups of ratchets are symmetrically distributed in mirror images, and a compression spring is provided at the bottom of one of the two groups of ratchets; in the design stage, if too large a wire diameter, too small a pitch, and too many effective turns are selected, it will cause the elastic force of the spring to be excessive, thereby causing the preload force of the auxiliary spring to exceed the normal range. For this reason, the operator will use a professional force measuring device to directly measure the preload force of the auxiliary spring. The device can detect the situation where the preload force of the auxiliary spring is too large through the setting of the ratchet and the compression spring.

[0019] Preferably, a cavity is further provided on the workbench, and a centering component is further provided in the cavity, and the centering component includes an adjusting rod, a pull rod and a receiving block, the adjusting rod is connected in the cavity via an axis rotation, the pull rod is provided at both ends of the adjusting rod, and the receiving block is provided on the adjusting rod.

[0020] Preferably, the two side walls of the receiving block are in contact with the side walls of the cavity, the adjusting rod is arranged along the extension line of the rotating shaft, the receiving block is limited in the cavity, and then the receiving block performs linear reciprocating motion under the drive of the adjusting rod.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The device uses a single drive source to drive the rotating rod, and the movement of the rotating rod drives the clamping rod to complete the compression operation of the auxiliary spring. No additional drive source is required to achieve this function, which improves the coordinated operation between components. At the same time, this design simplifies the assembly process, reduces the assembly steps, and reduces the complexity of the operation. Operators only need to follow the established steps to efficiently complete the assembly task without complex adjustments or additional operations, which significantly improves the assembly efficiency.

[0023] 2. By setting the rotating rod and the rotating assembly, the compression force of the auxiliary spring can be effectively controlled to prevent the auxiliary spring from being over-compressed, thereby ensuring the structural integrity of the auxiliary spring. The control mechanism enables the device to remain stable during the assembly process, reducing the risk of structural deformation or damage caused by excessive or uneven compression, thereby improving the stability of the entire device during use.

[0024] 3. Through the linkage mechanism of ratchet, compression spring and fixed rod, it is possible to detect whether the preload force of the auxiliary spring is appropriate during the installation process. Once the preload force is too large, the device will press down the compression spring through the spring to deflect the fixed rod to ensure that the housing can only be separated from the workbench when the preload force of the auxiliary spring is appropriate, thereby ensuring the installation quality. Reasonable preload force can avoid equipment failure caused by excessive elastic force of the spring during use, and improve the operating stability and reliability of the equipment.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 8 The present invention provides a high-precision constant-force spring support and hanger semi-automatic assembly platform, and the technical solution is as follows:

[0036] As an embodiment of the present invention, refer to Figures 1-2 A high-precision constant-force spring support and hanger semi-automatic assembly platform comprises a workbench 1, a shell 2 arranged on the workbench 1, two groups of brackets 3 arranged in the shell 2, an auxiliary spring 4 arranged between the bracket 3 and the inner wall of the shell 2, and a main spring 5 arranged in the middle of the shell 2, and also comprises a rotating assembly 6 arranged on the workbench 1, the rotating assembly 6 is arranged directly below the main spring 5, and two groups of moving rods 7 are also arranged on the rotating assembly 6, and a clamping rod 8 is arranged on the moving rod 7, and the clamping rod 8 is clamped on the end surface of the bracket 3. The rotating assembly 6 is also provided with a driving member 9, and the driving member 9 drives the rotating assembly 6 to rotate clockwise. When the rotating assembly 6 rotates and drives the two groups of moving rods 7 to move the same distance to both sides, the clamping rod 8 thereon compresses the two groups of auxiliary springs 4;

[0037] It can be seen that in the prior art, there are many problems with the method of relying on the coordinated operation of the hydraulic cylinder and the screw drive mechanism to compress the auxiliary spring 4 to install the main spring 5: on the one hand, this method has extremely high requirements on the accuracy and synchronization of the equipment. Once deviation occurs, it will cause uneven tension on the auxiliary spring 4. On the other hand, the hydraulic cylinder is easily affected by factors such as pressure fluctuations in the hydraulic system and oil contamination during movement, resulting in a decrease in movement accuracy, and then making the tension of the auxiliary springs 4 on both sides not completely consistent.

[0038] In view of the above problems, the present invention proposes an improved solution, which is to set a rotating assembly 6, and use its rotation to drive two groups of clamping rods 8 to compress the two groups of auxiliary springs 4 to both sides. During the compression process, the rotating assembly 6 can control the compression force, thereby effectively preventing the auxiliary springs 4 from being over-compressed and protecting the structural integrity of the auxiliary springs 4. This design not only improves stability, but also reduces the driving source and assembly steps, and is simple to operate while improving the overall installation efficiency and reliability.

[0039] Secondly, the clamping rod 8 can also adapt to supports and hangers of different specifications by adjusting its stroke. This flexibility enables the assembly platform to meet the needs of various application scenarios, thereby improving the versatility and economy of the equipment.

[0040] As an embodiment of the present invention, refer to Figure 2 The bracket 3 includes a rotating rod 31, a support rod 32 and a baffle 33. The rotating rod 31 is provided with two groups and is rotatably connected in the shell 2. The support rod 32 is arranged on the rotating rod 31, and the baffle 33 is arranged on the support rod 32. Two groups of auxiliary springs 4 are arranged between the baffle 33 and the inner wall of the shell 2. The rotating rod 31 drives the auxiliary spring 4 to provide additional supporting force according to the actual load conditions. The two work together, which can help the main spring share part of the load and ensure that the support bracket maintains a stable supporting force under different working conditions.

[0041] As an embodiment of the present invention, refer to Figures 3-4 The rotating assembly 6 includes a rotating shaft 61, a rotating rod 62 and a movable groove 63. The rotating shaft 61 is arranged on the side wall of the workbench 1 and is directly below the main spring 5. The rotating rod 62 is arranged on the rotating shaft 61. The movable groove 63 is opened at both ends of the rotating rod 62. The rotating shaft 61 is located in the middle of the rotating rod 62. When the rotating shaft 61 rotates, it drives the rotating rod 62 to rotate.

[0042] As an embodiment of the present invention, refer to Figure 4The movable rod 7 includes a movable block 71, a telescopic rod 72 and a fixed rod 73. The movable block 71 is provided with two groups and is movably connected in the movable groove 63. The telescopic rod 72 is provided at the end of the movable block 71, and the fixed rod 73 is provided on the telescopic rod 72. The fixed rod 73 is made of high-carbon high-alloy steel. The movable block 71 is movably connected to both ends of the rotating rod 62, and the movable block 71 will not be separated from the movable groove 63 when the rotating rod 62 rotates. The telescopic rod 72 can adjust its length according to the size of the constant force spring support bracket, thereby adjusting the spacing between the two groups of clamping rods 8.

[0043] As an embodiment of the present invention, refer to Figure 2 Two groups of limit grooves 74 are also provided on the side wall of the workbench 1 corresponding to the rotating shaft 61. The two groups of limit grooves 74 correspond to the telescopic rod 72. A limit block 75 is provided on the limit groove 74. The limit block 75 is connected to the telescopic rod 72. The end of the limit groove 74 is located within the perpendicular bisector of the auxiliary spring 4. The limit groove 74 enables the telescopic rod 72 to move in the horizontal direction when moving, and the limit groove 74 limits the moving distance of the telescopic rod 72 to prevent the auxiliary spring 4 from being over-compressed.

[0044] As an embodiment of the present invention, refer to Figure 3 The driving member 9 includes a base 91 and a motor 92. The base 91 is arranged on the side wall of the workbench 1 corresponding to the rotating rod 62. The motor 92 is arranged on the base 91. The output shaft of the motor 92 is arranged on the rotating shaft 61. The motor 92 is used to drive the rotating rod 62 on the rotating shaft 61 to rotate clockwise.

[0045] As an embodiment of the present invention, refer to Figures 5 to 7 The clamping rod 8 includes a connecting rod 81, a clamping block 82, a hinged rod 83 and a torsion spring 84. The connecting rod 81 is arranged on the fixed rod 73, and the clamping block 82 is arranged at the end of the connecting rod 81. The hinged rod 83 is rotatably connected to the clamping block 82 through the torsion spring 84. The clamping block 82 is in contact with the side wall of the baffle 33. The clamping rod 8 can be automatically clamped on the support rod 32 by thrust with the cooperation of the torsion spring 84. The central axis of the connecting rod 81 is parallel to the central axis of the rotating rod 31. The parallelism of the connecting rod 81 and the rotating rod 31 can ensure that the connecting rod 81 is not hindered by the rotating rod 31 when moving to the inside of the shell 2.

[0046] As an embodiment of the present invention, refer to Figure 4Two groups of ratchets 731 are also provided on the fixing rod 73. The two groups of ratchets 731 are symmetrically distributed. A compression spring 732 is provided at the bottom of one of the two groups of ratchets 731. In the design stage, a too large wire diameter, a small pitch, and too many effective turns will cause the elastic force of the spring to be too large, so that the preload force of the auxiliary spring 4 exceeds the normal range. For this reason, the operator will use a professional force measuring device to directly measure the preload force of the auxiliary spring 4 to prevent excessive pressure from causing the contact between the two to be closer, or even excessive extrusion. Excessive preload force will cause the shape of the auxiliary spring or the main spring to change, such as deformation or bending, thereby affecting the normal operation of the spring. The device compresses the auxiliary spring 4 and installs the main spring 5 After the installation is completed, the compression of the auxiliary spring is gradually released. When the rotating rod gradually leans against the main spring, the operator takes out the support bracket after the installation is completed. If the preload force of the auxiliary spring 4 is too large, the clamping rod 8 will be subjected to a greater rebound force when compressing the auxiliary spring 4, which will cause the compression spring 732 under the ratchet 731 to be compressed downward. When the preload force of the auxiliary spring 4 is within an appropriate range, the compression spring 732 will not be pressed downward. When the ratchet 731 rotates, the limit of the fixing rod 73 is released, causing the fixing rod 73 to deflect. After the fixing rod 73 deflects, the fixing rod 73 is no longer parallel to the rotating rod 31. At this time, the shell cannot be separated from the workbench. During the installation process, the linkage mechanism of the ratchet 731 and the compression spring 732 can effectively detect whether the preload force of the auxiliary spring 4 is too large. If the preload force is too large, the device will deflect the fixing rod 73 by pressing down the compression spring 732 to ensure that the shell can be separated from the workbench only when the preload force of the auxiliary spring 4 is appropriate, thereby ensuring the integrity and quality of the installation process. Reasonable preload force can avoid equipment failure caused by excessive elastic force of the spring during use, thereby improving the operating stability and reliability of the equipment.

[0047] As an embodiment of the present invention, refer to Figure 2 The workbench 1 is also provided with a cavity 10, and a centering assembly 11 is also provided in the cavity 10. The centering assembly 11 includes an adjusting rod 111, a pull rod 112 and a receiving block 113. The adjusting rod 111 is connected to the cavity 10 via an axis rotation, the pull rod 112 is provided at both ends of the adjusting rod 111, and the receiving block 113 is provided on the adjusting rod 111. In order to ensure that the support rod 32 can be aligned with the clamping rod 8 when the housing 2 is placed on the workbench 1, a centering assembly is provided. 11. The centering component 11 can ensure that the two groups of auxiliary springs 4 are subjected to the same pressure. The operator first places the support bracket on the receiving block 113 so that the side wall of the support bracket fits with the receiving block 113, and then pushes the receiving block 113. When pushing one group of receiving blocks 113, the adjusting rod 111 is driven to deflect. During the deflection, the pull rod 112 pulls the two groups of receiving blocks 113 closer to each other until the two groups of receiving blocks 113 fit with the side wall of the support bracket and the support bracket is in the middle position.

[0048] As an embodiment of the present invention, refer to Figure 1 The two side walls of the receiving block 113 are in contact with the side walls of the cavity 10, the adjusting rod 111 is arranged along the extension line of the rotating shaft 61, the receiving block 113 is limited in the cavity 10, and then the receiving block 113 performs a linear reciprocating motion driven by the adjusting rod 111, and the symmetry line between the two groups of receiving blocks 113 coincides with the center line of the rotating shaft 61.

[0049] Working principle: The operator first places the support and hanger on the receiving block 113 to ensure that the side wall of the support and hanger fits tightly with the receiving block 113. Then, the operator pushes a set of receiving blocks 113 to drive the adjustment rod 111 to deflect. During the deflection process, the pull rod 112 pulls the two sets of receiving blocks 113 closer to each other until the two sets of receiving blocks 113 are completely in contact with the side wall of the support and hanger, so that the support and hanger is in the middle position and corresponds to the rotating shaft 61. Figure 8 After the position of the support and hanger is determined, the operator continues to push the support and hanger toward the direction of the rotating shaft 61. During this process, the two groups of clamping rods 8 will be clamped into the bracket 3, and the end of the clamping rod 8 is located in the middle of the auxiliary spring 4. At this time, the motor 92 is started, and the motor 92 drives the rotating rod 62 to rotate clockwise. During the rotation process, the rotating rod 62 pushes the telescopic rods 72 at both ends to both sides. During the movement, the telescopic rod 72 drives the clamping rod 8 to evenly compress the auxiliary spring 4, and limits the moving distance of the telescopic rod 72 through the limit groove 74, thereby preventing the auxiliary spring 4 from being over-compressed. After completing the above steps, the main spring 5 is sent into the housing 2 for assembly, and the rotating rod 62 is restored to release the elastic force of the auxiliary spring 4 and abut against the main spring 5, and finally the assembly is completed. The device is provided with a rotating rod 62, and its rotation drives the two groups of clamping rods 8 to evenly compress the two groups of auxiliary springs 4 to both sides. During the compression process, the rotating rod 62 can effectively control the compression force, preventing the auxiliary spring 4 from being over-compressed and protecting its structural integrity while applying the same pressure to both sides. This design not only improves the stability of the device, but also reduces the drive source and assembly steps, making the operation simple, while improving the overall installation efficiency and reliability.
