[0020] Such as Figures 1 to 6As shown in the figure, a high-strength precision-fitting flange assembly includes a main body support and stabilizer plate 1. At the lower right corner of the main body support and stabilizer plate 1, there is a quarter-cylindrical main body splicing and fitting flange column 2. At the lower right of the main body splicing and fitting flange column 2, there is a cylindrical flange fitting and combination groove 3 with the same central axis. When in use, four products are spliced together to form a central fitting hole at this position. On the end face of the main body splicing and fitting flange column 2, there are circumferentially distributed flange fastening and connecting holes 4, through which the overall fixed connection of the flange is carried out by cooperating with fastening bolts. On the left side of the main body support and stabilizer plate 1, there is a trapezoidal first splicing and limiting combination groove 6 with an opening to the left. At the upper end of the main body support and stabilizer plate 1, there is a second splicing and limiting combination groove 7 with an opening to the outside, which can be accurately combined with the fitting guide rails around the pipeline during assembly, making the accuracy and stability of each upper component during installation and fitting better. At the same time, it can play an auxiliary role in installation and fitting, making the manual operation during assembly more convenient. The width of the inner side of the first splicing and limiting combination groove 6 is greater than that of the outer side, and the size of the inner side of the second splicing and limiting combination groove 7 is less than the width of the outer side. The existence of the assembly tolerance of mutual cooperation and avoidance of positions can prevent the occurrence of difficult combination, and at the same time, they can also form the role of mutual calibration and cooperation during assembly, ensuring more reliable fitting accuracy. On the front of the main body support and stabilizer plate 1, there are overall safety fastening holes 8, through which the main body can be more reliably reinforced. At the outer edge position of the main body splicing and fitting flange column 2, there is an assembly and combination avoidance chamfer structure, making the combination operation during fitting more convenient. It adopts a new structural design. When in use, four flange assemblies are spliced and fitted to form a relatively large flange part. The splicing method can make the installation more flexible. And through the splicing and limiting fitting grooves arranged in different outer directions, it can be accurately combined and connected with the limiting guide rails at the installation position. And during splicing, there is no need for manual or lifting tool support. The operation during splicing is easier, and the overall splicing accuracy is more guaranteed. The combination operation during installation is more convenient. During later disassembly and assembly, it can be disassembled in a decentralized manner, and there will be no damage to surrounding products due to its relatively large volume during the disassembly and assembly process, effectively improving the safety and convenience during maintenance.
[0021] Preferably, on the front of the main body splicing and fitting flange column 2, there are fastening and positioning fitting holes 5. During installation, when connecting with a sealing ring at the end position, accurate positioning and fitting can be carried out, making the installation operation of auxiliary accessories such as sealing rings more convenient and the position accuracy higher.
[0022] Preferably, on the upper left and right sides of the main body support and stabilizer plate 1, there are avoidance and fitting inclined surface structures respectively, so that there is more space at both sides during fitting, and the safety during splicing and installation is higher.
[0023] Preferably, chamfer structures for facilitating fastening combination are respectively provided at the front and rear edge positions of the flange fastening connection holes 4, which makes the operation more convenient when placing the fastening bolts and improves the combination efficiency during combination.
[0024] Preferably, the projection shape of the first splicing limit combination groove 6 in the front-rear direction is an isosceles trapezoid, which makes the combination strength higher when this position is combined with the installation guide rail, and the combination stability can also be further improved.
[0025] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements or replacements can be made, and these improvements or replacements should also be regarded as the protection scope of the present invention.
