Description

Technical Field

[0001] The present invention relates to the technical field of steel assembly, and in particular to an assembly and positioning device for a round tube steel component and a positioning and assembly method. Background Art

[0002] The assembly and positioning of circular steel components refers to the process of ensuring that each component is accurately and securely positioned and assembled according to design requirements during the installation of circular steel structures. The main purpose of positioning is to ensure that all parts of the steel components are accurately connected during assembly, thereby ensuring the stability, precision, and safety of the structure.

[0003] In practical applications, existing assembly tooling still presents several problems. For example, during the clamping process of a circular steel tube, existing assembly tooling can only achieve the clamping of the circular steel tube. After clamping, the two circular steel tubes to be assembled must be positioned, ensuring that the two clamped circular steel tubes are at the same horizontal position to facilitate subsequent assembly. However, existing assembly tooling cannot achieve alignment between the two circular steel tubes during the clamping process, requiring subsequent adjustment and positioning. This not only wastes time but also makes it difficult to ensure the accuracy of the subsequent alignment. Summary of the Invention

[0016] A method for positioning and assembling a circular tube steel member comprises the following steps:

[0017] S1: First, the two round tubes to be assembled are placed inside the two clamping sleeves respectively. By controlling the start-up of motor 2, the motor 2 can drive the rotating shaft to rotate, thereby driving the multiple mounting plates 1 to rotate, and then driving the round tubes placed inside them to move toward the center point of the clamping sleeve, so that the round tubes placed inside the two clamping sleeves are centered and can achieve stable clamping;

[0018] S2: The first and second positioning belts are respectively sleeved on the outer surface of the round tube, so that the first and second positioning belts can provide a downward pressure on the round tube, so that when the round tube is placed inside the multiple clamping rods, it can be tightly attached to the outside of the lowest clamping rod, limiting the position of the round tube, making the round tube more stable during the subsequent assembly and clamping process, and will not shake inside the clamping sleeve;

[0019] S3: During the process of clamping the round tube, the round tube moves toward the middle of the clamping sleeve, which can absorb the protective oil inside the storage box into the interior of the cavity one through the connecting pipe. During the process of releasing the round tube, the positioning belt one loses its upward traction, and the protective oil originally absorbed into the cavity one can be squeezed into the interior of the diversion pipe through the delivery pipe. Finally, it is sprayed downward in the form of atomization and scattered on the assembly part of the two round tubes, which can effectively protect the assembly part of the round tubes.

[0020] S4: Through the central clamping of the circular tube, the positioning belt 2 is driven to move upward, squeezing the air between the two discs 2 into the interior of the vertical tube and spraying it upward through the air outlet frame. When the protective oil is sprayed downward in an atomized state, some of the protective oil will fall downward. The wind blown out by the air outlet frame can blow the falling protective oil upward and make the protective oil that falls downward adhere to the bottom of the assembly part of the two circular tubes, further improving the protection effect.

[0021] The present invention provides a circular tube steel component assembly and positioning device and positioning and assembly method, the beneficial effects of which include:

[0022] 1. By setting up an assembly fixture mechanism and controlling the start-up of motor 2, the rotating shaft can be driven to rotate during the start-up of motor 2. When the worm rotates, the outer sleeve can be driven to rotate on the outer surface of the clamping sleeve, thereby driving multiple mounting plates to rotate, causing multiple clamping rods to change their positions, and then driving the circular tube placed inside to move toward the center point of the clamping sleeve, and stably clamping the circular tube, thereby realizing the centering alignment of the circular tubes placed inside the two clamping sleeves and achieving the purpose of stable clamping.

[0023] 2. By setting up an assembly protection mechanism, during the process of clamping the round tube, the round tube can be moved toward the middle of the clamping sleeve, thereby driving the two cavities 2 set inside the cylinder 1 to move toward each other inside the cylinder 1, and the protective oil inside the storage box can be sucked into the interior of the cavity 1 through the connecting pipe. After the assembly is completed, during the process of releasing the round tube, the positioning belt 1 loses its upward traction force and can continue to fit the outer surface of the round tube under the action of the spring 1. The two discs 1 can then move toward both sides of the cylinder 1 under the action of the spring 1, squeezing the protective oil originally sucked into the cavity 1 into the inside of the diverter pipe through the delivery pipe, and finally spraying it downward in atomization and scattering it on the assembly part of the two round tubes, thereby effectively protecting the assembly part of the round tube.

[0024] 3. By setting up an assembly surface cleaning mechanism and clamping the circular tube in the center, the positioning belt 2 is driven to move upward, and the two discs 2 are driven to move toward each other inside the cylinder 2, so that the air between the two discs 2 is squeezed into the inside of the vertical tube, and finally sprayed upward through the air outlet frame. When the protective oil is sprayed downward in an atomized state, some of the protective oil will fall downward. At this time, the wind blown out by the air outlet frame can blow the falling protective oil upward, and make the protective oil falling downward adhere to the bottom of the assembly part of the two circular tubes, that is, the part that the protective oil falling downward cannot touch, thereby further improving the protection effect.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 making creative efforts shall fall within the scope of protection of the present invention.

[0038] Reference Figures 1-10 The present invention provides a technical solution: a circular tube steel member assembly and positioning device, comprising a base 1, L-shaped brackets 2 fixedly mounted at the four corners of the top surface of the base 1, an assembly platform 4 clamped inside the L-shaped bracket 2, a hydraulic telescopic rod 3 installed between the assembly platform 4 and the base 1, two assembly plates 6 provided on the top surface of the base 1, and an assembly fixture mechanism 7 provided on the top surfaces of the two assembly plates 6;

[0039] The assembly fixture mechanism 7 includes a mounting base 701, which is fixedly mounted on the top surface of the assembly disk 6. The internal clamping sleeve 702 holds the circular tube 8. The internal clamping sleeve 702 is fixedly mounted on the mounting base 701. The outer surface of the clamping sleeve 702 is sleeved with two outer sleeves 703. The two outer sleeves 703 are respectively sleeved on the two ends of the clamping sleeve 702. Both ends of the clamping sleeve 702 are rotatably mounted with multiple mounting plates 705. The multiple mounting plates 705 are all equidistantly installed, and the lengths of the multiple mounting plates 705 increase sequentially.

[0040] A plurality of mounting plates 704 are rotatably installed on one side surface of the two outer sleeves 703. The number of the plurality of mounting plates 704 is equal to that of the mounting plate 2 705, and the mounting positions correspond. A clamping rod 706 is provided inside the mounting plate 1 704 and the mounting plate 2 705. One end of the clamping rod 706 is rotatably installed inside the mounting plate 1 704, and the other end of the clamping rod 706 is movably inserted into the inside of the mounting plate 2 705. A worm gear 707 is fixedly installed on the bottom surface of one of the outer sleeves 703, and two positioning frames 708 are fixedly installed on one side surface of the mounting seat 701. A rotating shaft 709 is rotatably installed inside the two positioning frames 708. A worm 710 is fixedly sleeved on the outer surface of the rotating shaft 709, and the worm 710 and the worm gear 707 are meshed with each other. A motor 2 711 is fixedly installed on the top surface of the assembly disk 6, and the output end of the motor 2 711 is fixedly connected to one end of the rotating shaft 709.

[0041] During operation, in actual use, the two round tubes 8 to be assembled are first placed inside the two clamping sleeves 702 respectively, and are located between the clamping rods 706. When the round tubes 8 are placed, the motor 2 711 is controlled to start. During the start-up process of the motor 2 711, the rotating shaft 709 can be driven to rotate. When the worm 710 rotates, the outer sleeve 703 can be driven to rotate on the outer surface of the clamping sleeve 702, thereby driving multiple mounting plates 1 704 to rotate, causing multiple clamping rods 706 to change their positions, and then the round tubes 8 placed inside can be driven to move toward the center point of the clamping sleeve 702, and the round tubes 8 can be stably clamped, thereby achieving the centering alignment of the round tubes 8 placed inside the two clamping sleeves 702, and achieving the purpose of stable clamping, avoiding the problem that the existing clamping mechanism cannot center the two round tubes 8. After the two round tubes 8 are clamped and aligned, the subsequent assembly operation of the two round tubes 8 can be carried out.

[0042] A through slot 5 is provided in the middle of the top surface of the base 1. Two clamping blocks 11 are movably connected to the interior of the through slot 5. A clamping block 2 12 is provided above each of the two clamping blocks 11. A C-shaped connecting frame 13 is fixedly connected to one side surface of the clamping block 11 and the clamping block 2 12. A mounting shaft 19 is rotatably installed inside the clamping block 11 and the clamping block 2 12. One end of the mounting shaft 19 is fixedly connected to the bottom surface of the assembly disk 6. A motor 3 20 is fixedly installed on one side surface of the clamping block 2 12. The output end of the motor 3 20 A gear 21 is fixedly installed, and a gear 22 is fixedly sleeved on the outer surface of the mounting shaft 19. The gear 22 and the gear 21 are meshed with each other. A toggle plate 14 is fixedly installed on one side surface of the clamping block 11. A threaded hole is opened inside the toggle plate 14, and a threaded rod 15 is sleeved on the internal thread of the toggle plate 14. A motor 16 is fixedly installed on the top surface of the base 1. A pulley 17 is fixedly installed on the output end of the motor 16 and the middle part of the threaded rod 15. A toothed belt 18 is sleeved between the two pulleys 17.

[0043] During operation, after the two round tubes 8 are aligned and clamped in the center, the motor 16 can be controlled to start. During the starting process of the motor 16, the two toggle plates 14 can be driven to move toward each other under the action of the threaded rod 15, that is, the two clamping blocks 11 inside the through groove 5 can be driven to move toward each other, and then the two assembly disks 6 can be moved toward each other until one end of the two round tubes 8 touches, and then the assembly operation of the two round tubes 8 can be carried out.

[0044] During this process, the motor three 20 can be controlled to rotate, and the two assembly disks 6 can be driven to rotate under the action of gear one 21 and gear two 22. When assembling the two bevel-end circular tubes 8, it is only necessary to control the assembly disk 6 to rotate to a suitable position, and then make the bevel ends of the two circular tubes 8 fit together, and then start the control motor one 16 to make the bevel ends of the two circular tubes 8 fit together, so that the circular tubes 8 with bevel ends can be quickly assembled, thereby further improving the overall practicality of the device and increasing the overall scope of application of the device. In the process of assembling the bevel-end circular tube 8, the circular tube 8 cannot be fit and limited, that is, the positioning belt one 914 and the positioning belt two 1001 cannot be sleeved on the outer surface of the circular tube 8.

[0045] 902. Two connecting pipes 903 are fixedly connected to the surface, and a one-way valve 904 is fixedly installed on the outer surface of the two connecting pipes 903. One end of the two connecting pipes 903 extends to the inside of the two discs 1 920 respectively. Two groups of delivery pipes 905 are fixedly connected on both sides of the outer surface of the cylinder 1 901. The fixed point of the delivery pipe 905 is located at the position of the disc 1 920. The outer surface of the delivery pipe 905 is fixedly connected to the one-way valve 2 906. The top surface of the assembly disk 6 is fixedly connected to a stand 907. The top surface of the stand 907 is installed with a diversion pipe 908. One end of the two delivery pipes 905 is fixedly connected to the two sides of the diversion pipe 908. A liquid outlet pipe 1 909 and a liquid outlet pipe 2 910 are provided on one side surface of the diversion pipe 908. One end of the liquid outlet pipe 2 910 is fixedly connected to a liquid outlet frame 912. The bottom surface of the liquid outlet frame 912 is fixedly connected to multiple atomizing nozzles 913.

[0046] Working process: In the process of clamping the round tube 8 at the flat end, it is only necessary to sleeve the positioning belt 1 914 and the positioning belt 2 1001 on the outer surface of the round tube 8 respectively, so that the positioning belt 1 914 and the positioning belt 2 1001 can provide a downward pressure on the round tube 8, so that the round tube 8 can be tightly fitted on the outside of the lowest clamping rod 706 when placed inside the multiple clamping rods 706, effectively limiting the position of the round tube 8, so that the round tube 8 can be more stable in the subsequent assembly and clamping process, and will not be stuck in the clamping sleeve 702. There is a problem of internal shaking. At the same time, through the arrangement of positioning belt 1 914 and positioning belt 2 1001, the two ends of the round tube 8 can be in a state of two-force balance. This not only allows the round tube 8 to be stably moved and clamped in the middle of the clamping sleeve 702 during the clamping process, but also can press the round tube 8 tightly against the outside of the lowest clamping rod 706 when taking it out, so that the round tube 8 can always remain in a limited state inside the clamping sleeve 702, and can be more stable during the clamping and releasing processes.

[0047] Moreover, in the process of clamping the circular tube 8, the circular tube 8 can be moved toward the middle of the clamping sleeve 702, that is, in the process of clamping, the circular tube 8 can be moved upward, that is, the positioning belt 1 914 can be driven to move upward, thereby driving the two cavities 2 923 sleeved inside the cylinder 1 901 to move toward each other inside the cylinder 1 901, thereby driving the two discs 1 920 to move toward each other inside the cylinder 1 901. When the two discs 1 920 move toward each other, the protective oil inside the storage box 902 can be sucked into the interior of the cavity 1 922 through the connecting pipe 903. After the assembly is completed, when the circular tube 8 is released, the positioning belt 1 914 loses its upward traction force and can be under the action of the spring 1 921. The protective oil is then squeezed into the shunt pipe 908 through the delivery pipe 905, and finally atomized and sprayed downward through the liquid outlet pipe 1 909, the liquid outlet pipe 2 910, the liquid outlet rack 912 and the atomizing nozzle 913, and finally scattered on the assembly parts of the two circular tubes 8, which can effectively protect the assembly parts of the circular tubes 8. Among them, the protective oil is not limited to a single one, and can be a variety of mineral oil-based anti-rust oil, synthetic oil-based anti-rust oil, etc. Among them, the delivery pipe 905 and the connecting pipe 903 are located at one end of the cylinder 1 901, and the two discs 1 920 are located near the middle of the cylinder 1 901.

[0048] The outer surface of cylinder 1 901 at cavity 2 923 is fixedly connected to a rectangular tube 917, one end of the rectangular tube 917 is fixedly connected to an air outlet pipe 918, one end of the air outlet pipe 918 is fixedly connected to a plug tray rack 919, and the plug tray rack 919 is plugged into one end of the circular tube 8.

[0049] During operation, when the two motors three 20 move toward each other, the air inside the cavity two 923 can be squeezed into the inside of the rectangular tube 917, and finally enter the inside of the air outlet pipe 918 through the rectangular tube 917, and finally enter the inside of the plug rack 919 through the air outlet pipe 918, and is sprayed toward the inside of the circular tube 8 through the plug rack 919, blowing the impurities remaining inside the circular tube 8 away from the inside of the circular tube 8, thereby achieving the purpose of effectively cleaning the circular tube 8.

[0050] Among them, the liquid outlet pipe 2 910 is inserted into the inside of the liquid outlet pipe 1 909, and the liquid outlet frame 912 can be extended according to the length of the circular tube 8, so that the liquid outlet frame 912 can adapt to the use of circular tubes 8 of different lengths, so that the position of the liquid outlet frame 912 can be adjusted at one end of the circular tube 8.

[0051] The top surface of the assembly table 4 is provided with an assembly surface cleaning mechanism 10, which includes a second positioning belt 1001 and four installation boxes 1002. The four installation boxes 1002 are symmetrically arranged in pairs. The two ends of the second positioning belt 1001 are respectively located inside the two installation boxes 1002 symmetrically along the through groove 5. The inner walls of the installation boxes 1002 are penetrated with rectangular grooves 1003. The inner movable card of the rectangular groove 1003 is connected with a connecting block 1004. A fixing seat 2 1005 is fixedly installed on one side surface of the connecting block 1004. The two ends of the second positioning belt 1001 are respectively sleeved on the inside of the fixing seat 2 1005 inside the two installation boxes 1002. The surface of one side of the fixing seat 2 1005 is A connecting plate 1006 is fixedly connected, and a spring 2 1007 is fixedly connected to one side surface of the connecting plate 1006 and an inner wall of one side of the installation box 1002. A cylinder 2 1008 is provided between the four installation boxes 1002. Two discs 2 1009 are movably connected to the internal clamping of the cylinder 2 1008. One side surface of the two discs 2 1009 is fixedly connected to a connecting shaft 1010. One end of the two connecting shafts 1010 is fixedly connected to a connecting plate 2 1011. Both ends of the connecting plate 2 1011 are fixedly connected to the two connecting blocks 1004 respectively. A vertical pipe 1012 is fixedly connected to the outer surface of the cylinder 2 1008, and one end of the vertical pipe 1012 is fixedly connected to an air outlet frame 1013.

[0052] During operation, in actual use, the central clamping of the round tube 8 can drive the positioning belt 2 1001 to move upward, thereby driving the fixing seat 2 1005 to move toward each other inside the installation box 1002, thereby driving the connecting block 1004 to move synchronously inside the rectangular groove 1003, and the movement of the connecting block 1004 drives the two connecting plates 2 1011 to move toward each other, and under the action of the connecting shaft 1010, drives the two discs 2 1009 to move toward each other inside the cylinder 2 1008, thereby connecting the two discs 2 1009 to the inner wall of the cylinder 1008. The air is squeezed into the interior of the vertical tube 1012 and finally sprayed upward through the air outlet rack 1013. When the protective oil is sprayed downward in an atomized state, a part of the protective oil will fall downward. At this time, the wind blown out through the air outlet rack 1013 can blow the falling protective oil upward, and make the protective oil falling downward adhere to the bottom of the assembly part of the two circular tubes 8, that is, the part that the protective oil falling downward cannot touch, thereby achieving the purpose of being able to more comprehensively adhere to the assembly part of the two circular tubes 8, and can further protect the circular tubes 8.

[0053] A method for positioning and assembling a circular tube steel member comprises the following steps:

[0054] S1: First, the two round tubes 8 to be assembled are placed inside the two clamping sleeves 702 respectively, and the second motor 711 is controlled to start. During the startup of the second motor 711, the rotating shaft 709 can be driven to rotate, thereby driving the multiple mounting plates 1 704 to rotate, and then driving the round tubes 8 placed inside them to move toward the center point of the clamping sleeve 702, so that the round tubes 8 placed inside the two clamping sleeves 702 are centered and aligned, and stable clamping can be achieved;

[0055] S2: The first positioning belt 914 and the second positioning belt 1001 are respectively sleeved on the outer surface of the round tube 8, so that the first positioning belt 914 and the second positioning belt 1001 can provide a downward pressure on the round tube 8, so that when the round tube 8 is placed inside the multiple clamping rods 706, it can be tightly attached to the outside of the lowest clamping rod 706, limiting the position of the round tube 8, so that the round tube 8 can be more stable during the subsequent assembly and clamping process, and will not shake inside the clamping sleeve 702;

[0056] S3: During the clamping process of the round tube 8, the round tube 8 moves toward the middle of the clamping sleeve 702, and the protective oil inside the storage box 902 can be sucked into the interior of the cavity 1 922 through the connecting pipe 903. During the release process of the round tube 8, the positioning belt 1 914 loses its upward traction force, and the protective oil originally sucked into the interior of the cavity 1 922 can be squeezed into the interior of the diversion pipe 908 through the delivery pipe 905. Finally, it is sprayed downward in the form of atomization and scattered on the assembly part of the two round tubes 8, thereby effectively protecting the assembly part of the round tube 8.

[0057] S4: Through the central clamping of the circular tube 8, the positioning belt 2 1001 is driven to move upward, and the air between the two discs 2 1009 is squeezed into the inside of the vertical tube 1012, and sprayed upward through the air outlet rack 1013. When the protective oil is sprayed downward in an atomized state, a part of the protective oil will fall downward. The wind blown out by the air outlet rack 1013 can blow the falling protective oil upward, and enable the protective oil falling downward to adhere to the parts that the protective oil falling downward cannot touch, thereby further improving the protective effect.

[0058] Specifically, the working process or working principle of the round tube steel component assembly positioning device and positioning assembly method is as follows: when in use, first place the two round tubes 8 to be assembled inside the two clamping sleeves 702 respectively, and between the clamping rods 706. After the round tubes 8 are placed, the motor 2 711 is controlled to start. During the process of starting the motor 2 711, the rotating shaft 709 can be driven to rotate. When the worm 710 rotates, the outer sleeve 703 can be driven to rotate on the outer surface of the clamping sleeve 702, thereby driving the multiple mounting plates 1 704 to rotate, causing the multiple clamping rods 706 to change position, and then the round tubes 8 placed inside can be driven toward the clamping sleeve 7 02, and can stably clamp the circular tube 8, thereby realizing the center alignment of the circular tube 8 placed inside the two clamping sleeves 702, and achieving the purpose of stable clamping. In the process of clamping the circular tube 8 at the flat end, it is only necessary to respectively sleeve the positioning belt 1 914 and the positioning belt 2 1001 on the outer surface of the circular tube 8, so that the positioning belt 1 914 and the positioning belt 2 1001 can provide a downward pressure on the circular tube 8, so that when the circular tube 8 is placed inside the multiple clamping rods 706, it can fit tightly on the outside of the lowest clamping rod 706, effectively limit the circular tube 8, and make the circular tube 8 more stable during the subsequent assembly and clamping process.

[0059] During the process of clamping the circular tube 8, the circular tube 8 can be moved toward the middle of the clamping sleeve 702, thereby driving the two cavities 2 923 set inside the cylinder 1 901 to move toward each other inside the cylinder 1 901, and the protective oil inside the storage box 902 can be sucked into the interior of the cavity 1 922 through the connecting pipe 903. After the assembly is completed, during the process of releasing the circular tube 8, the positioning belt 1 914 loses its upward traction force and can continue to fit the outer surface of the circular tube 8 under the action of the spring 1 921. The two discs 1 920 can move toward the two sides of the cylinder 1 901 under the action of the spring 1 921, and the protective oil originally sucked into the cavity 1 922 is squeezed into the diversion pipe 908 through the delivery pipe 905. The oil is sprayed downward in an atomized state and scattered on the assembly parts of the two circular tubes 8, which can effectively protect the assembly parts of the circular tubes 8. Through the central clamping of the circular tube 8, the positioning belt 1001 is driven to move upward, and the two discs 1009 are driven to move toward each other inside the cylinder 1008, so that the air between the two discs 1009 is squeezed into the interior of the vertical tube 1012, and finally sprayed upward through the air outlet rack 1013. When the protective oil is sprayed downward in an atomized state, a part of the protective oil will fall downward. At this time, the wind blown out by the air outlet rack 1013 can blow the falling protective oil upward, and make the protective oil falling downward adhere to the bottom of the assembly parts of the two circular tubes 8, that is, the part that the protective oil falling downward cannot touch.
