Description

Technical Field

[0001] The invention relates to the technical field of flange processing, in particular to flange hole position adaptive forming equipment. Background Art

[0002] Flange processing refers to the process of mechanical processing of connecting components such as pipes, valves, and equipment. It mainly includes turning, drilling, tapping and other processes to ensure that the flange's dimensional accuracy, sealing surface finish and bolt hole position meet standard requirements; the processed flange is used for sealing connections in pipeline systems and is widely used in petroleum, chemical, electric power and other industries.

[0003] When forming holes in small and medium-sized flanges, flange hole forming equipment is required. First, the blank flange is fixed on the workbench and aligned with the positioning fixture to ensure the reference. Then the equipment automatically completes the drilling and other processes according to the preset program. Some high-precision equipment will be equipped with an online detection system to correct errors in real time.

[0004] In the industrial field, the most common situation for flanges in wind power, ship propulsion systems, and large compressor units is "different sizes, different numbers of holes, but the same bolt hole diameter." The fundamental reason lies in differences in design standards and customized working conditions. The typical processing parameters of small and medium-sized flanges include 4 or 8 holes.

[0045] The working principle of the flange hole adaptive forming equipment is as follows:

[0046] By placing the flange in the rotary guide mechanism, the rotary guide mechanism drives several inner support columns 2 to support and fix the inner ring of the flange. When processing the small flange, the synchronous transmission mechanism is started to drive the first gear ring 7 to rotate, so that the first gear ring 7 drives several first drive rods 4 to rotate and the second drive rod 5. The lifting mechanism is started to make several drill bit bodies 6 at one end of the first drive rod 4 contact the surface of the small flange, and the small flange is synchronously drilled.

The drill body 6 is driven by the lifting mechanism to contact the middle flange for drilling. This design uses a multi-axis drilling method to achieve rapid processing of small and medium-sized flanges, without the need to position, drill, and retract the flanges one by one, thereby reducing equipment wear.

[0047] The flange is placed on the surface of the flange plate 15, and the turntable 13 is driven to rotate by the motor 2 16, so that the turntable 13 drives the multiple inner support columns 2 to move on the surface of the stable plate 12 through the driving groove 14. At the same time, the multiple inner support columns 2 expand and support the inside of the flange, completing the self-centering fixation of the flange and realizing the rapid positioning of the flange.

[0048] When the number of holes to be drilled needs to be changed, the motor 4 33 drives the synchronous wheel 2 32 to rotate, so that the synchronous wheel 2 32 drives the synchronous wheel 1 30 to rotate through the synchronous belt 31, so that the synchronous wheel 1 30 drives the screw rod 3 29 to rotate, and at the same time the screw rod 3 29 drives the bevel gear 25 to rotate, so that the bevel gear 25 drives the plurality of helical gears 26 to rotate, so that the helical gear 26 drives the plurality of screw rods 27 to rotate, and drives the plurality of moving blocks 28 on the surface of the plurality of screw rods 27 to slide inside the lifting plate 3, so that the plurality of moving blocks 28 drive the plurality of first drive rods 4 and the second drive rods 5 to move synchronously, so that the plurality of first drive rods 4 and the second drive rods 5 The gear 17 on the surface of the movable rod 5 engages the second gear ring 8, and at the same time, the second driving rod 5 drives several rotating rods 35 to displace synchronously, so that one end of the rotating rod 35 drives the limit block 36 to slide in the limit plate 34. When the screw rod 3 29 rotates, it drives the limit plate 34 to slide inside the support frame 18, so that the limit plate 34 drives the limit block 36 to move downward, and the limit block 36 drives the rotating rod 35 to slide inside the second driving rod 5, so that the several drill bit bodies 6 at one end of the rotating rod 35 are flush with the drill bit body 6 at one end of the first driving rod 4, completing the change in the number of holes to be drilled and synchronously adapting to the size of the flange, which is convenient and fast.
