Abstract
Description
Technical Field
[0001] This utility model relates to the field of flange reamers, and in particular to a clamping and fixing mechanism for flange reamers. Background Technology
[0002] In the existing technology, a flange, also called a flange disc or flange, is a part used to connect shafts to each other and to connect pipe ends. There are also flanges used on equipment inlets and outlets for connecting two pieces of equipment, such as reducer flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, a gasket, and bolts connected together as a combined sealing structure. A pipe flange refers to a flange used for piping in a pipeline system. When used on equipment, it refers to the inlet and outlet flanges of the equipment. Flanges have holes, bolts are used to tightly connect two flanges, and a gasket is used to seal between the flanges. Flanges are divided into threaded flanges, welded flanges, and clamp flanges. A hole expander, also known as a ring rolling mill, is an advanced piece of equipment for processing ring forgings. It is widely used in the production of ring parts in industries such as bearings, engineering machinery, petrochemicals, aerospace, and power generation. Flanges require a reamer for enlarging during processing. Currently, most reamers use simple fixing mechanisms to secure flanges, which can easily cause flange displacement and reaming failure, thus failing to meet the requirements for flange reaming. Therefore, we propose a clamping and fixing mechanism for flange reamers. Utility Model Content

The connecting plate 73 is fixed on the right end of the upper side of the connecting strip 72. The upper end of the connecting plate 73 has evenly distributed guide ports 74. The L-shaped fixing strip 61 is slidably connected inside the corresponding guide port 74. The input end of the hydraulic rod 71 is electrically connected to the output end of an external control switch group. By setting the pulling assembly 7, all the L-shaped fixing strips 61 are driven to move downward. By setting the rotating assembly 5, the rotating ring 41 is driven to rotate. By setting the squeezing assembly 4, all the sliding rods 33 are squeezed to move. The moving component 3 includes a strip groove 31, a slider 32, a slide rod 33, and a spring 34. The fixed disk 2 has evenly distributed strip grooves 31 inside, and the slider 32 is slidably connected inside the strip grooves 31.

[0018] The working principle of the clamping and fixing mechanism for a flange reaming machine provided by this utility model is as follows: When it is necessary to clamp the flange, the flange is first placed on the anti-slip plate 9 above the fixing plate 2. The anti-slip plate 9 increases friction to improve stability. Then, the motor 53 in the rotating assembly 5 is started. The motor 53 drives the gear 54 to rotate. The gear 54 meshes with the gear ring 51, thereby driving the rotating ring 41 to rotate on the mounting plate 1. The pressing block 42 inside the rotating ring 41 rotates accordingly and gradually presses the slide rod 33 in the moving assembly 3. The slide rod 33 is fixed on the slider 32. The slider 32 slides in the strip groove 31. The spring 34 is compressed, and the slider 32 moves. When the anti-slip plate 62 on the slider 32 is in contact with the outer edge of the flange, the flange can be initially fixed. Then, the hydraulic rod 71 in the pulling assembly 7 is activated. The telescopic arm of the hydraulic rod 71 pushes the connecting plate 73 downward through the connecting bar 72. The guide port 74 on the connecting plate 73 guides the L-shaped fixing bar 61 to slide downward along the axis. The limit block 63 restricts the stroke, so that the L-shaped fixing bar 61 presses the flange from above to achieve axial fixation. During the hole enlargement process, the radial and axial clamping forces work together to prevent the flange from shifting and ensure the hole enlargement accuracy. After the hole enlargement is completed, the hydraulic rod 71 resets, drives the L-shaped fixing bar 61 to rise, the motor 53 reverses, the pressing block 42 disengages from the slide bar 33, the spring 34 pushes the slider 32 and the slide bar 33 to reset, the L-shaped fixing bar 61 is radially loosened, and the flange can be removed. Throughout the process, the components work together to achieve reliable clamping through mechanical and hydraulic control.
[0019] It is worth noting that the external control switch group disclosed in the above embodiments is equipped with buttons that correspond one-to-one with the motor 53 and the hydraulic rod 71. The motor 53 and the hydraulic rod 71 can be freely configured according to the actual situation. The external control switch group controls the operation of the motor 53 and the hydraulic rod 71 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
