Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, in particular to a flange processing support. Background Art

[0002] Flange is a disc-shaped part used to connect two pipes. It is most common in pipeline engineering. Flanges are used in pairs. There are holes on the surface of the flanges. They are connected by bolts. At the ends of the two pipes that need to be connected, a flange is installed on each side. Low-pressure pipelines can use threaded flanges, and pressures above 4 kg use welded flanges. Add a gasket between the two flanges and then tighten them with bolts.

[0003] Since holes need to be drilled on the flange, the flange needs to be placed flat on the corresponding processing support, but the existing processing support has a simple structure. Since the inner diameters of flanges of different specifications are different, the traditional single processing support cannot meet the use of flanges of different specifications. Flanges of different specifications require processing supports of different sizes, which results in the need to replace the support at any time during processing, which is cumbersome to operate, inconvenient to disassemble and assemble, and increases production costs. In order to address this technical problem, a processing support for a flange is proposed. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] 1. By setting the horizontal screw, driving gear, transmission gear, moving plate and positioning wheel, the stable positioning operation of the flange to be processed placed on the base is realized, ensuring its stability during the processing, and the spacing between multiple positioning wheels can be flexibly adjusted, so that the device can adapt to flanges of various sizes within a certain range, thereby improving the applicability of the device.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all of the embodiments.

[0020] Reference Figure 1-3A flange processing support includes a base 1. The upper end surface of the base 1 is provided with an annular groove 9 and a plurality of rotating grooves 2. As shown in the figure, the annular groove 9 is V-shaped in vertical section, which is conducive to the waste generated by the flange processing falling into its inner bottom wall for collection.

[0021] A transmission chamber 11 is provided inside the base 1, and a driving gear 13 is rotatably provided on the inner wall of the transmission chamber 11. A power mechanism connected to the driving gear 13 is provided in the transmission chamber 11, and a horizontal screw 3 is rotatably provided in multiple rotating grooves 2. The horizontal screw 3 extends into the transmission chamber 11 and is connected to the driving gear 13 through a rotating mechanism. A movable plate 4 is threadedly sleeved on the horizontal screw 3, and a positioning wheel 5 is fixedly installed on the movable plate 4. A vertical screw 6 is rotatably provided on the positioning wheel 5, and a limit disk 7 is threadedly sleeved on the vertical screw 6.

[0022] The power mechanism includes a drive motor 12 installed in the transmission cavity 11. The output shaft of the drive motor 12 is fixedly connected to the driving gear 13. The drive motor 12 is a power device. After the drive motor 12 is started, it can directly drive the driving gear 13 connected to its output shaft to rotate.

[0023] The rotating mechanism includes a transmission gear 14 installed on the end of the horizontal screw 3. The driving gear 13 and the transmission gear 14 are both bevel gears. The driving gear 13 and the transmission gear 14 are vertically meshed. With the help of the above-mentioned driving gear 13 and the transmission gear 14, the power transmission of the drive motor 12 is realized, and the synchronous rotation of the four horizontal screws 3 is realized after the drive motor 12 is started.

[0024] A horizontal bar 10 is provided in the rotating groove 2, the horizontal bar 10 is parallel to the horizontal screw 3, and the horizontal bar 10 slides through the moving plate 4. A vertical bar 8 is installed on the upper end surface of the positioning wheel 5, the vertical bar 8 is parallel to the vertical screw 6, and the vertical bar 8 slides through the limiting plate 7. As shown in the figure, the horizontal bar 10 and the vertical bar 8 both play a limiting role, preventing the moving plate 4 from rotating with the horizontal screw 3, and preventing the limiting plate 7 from rotating with the vertical screw 6.

[0025] The arc-shaped outer wall of the positioning wheel 5 and the bottom wall of the limiting plate 7 are both provided with protective pads, which are made of rubber and have anti-skid patterns on the surface. The protective pads made of rubber and having anti-skid patterns play a protective and anti-skid role, avoiding friction damage to the outer wall of the flange.

[0026] When the utility model is used, the flange to be processed is placed at the center of the upper end surface of the base 1, and then the driving motor 12 is started. The driving motor 12 directly drives the active gear 13 to rotate, and the active gear 13 cooperates with the transmission gear 14 to drive the horizontal screw 3 to rotate. When the horizontal screw 3 rotates, the movable plate 4 threadedly mounted thereon can drive the positioning wheel 5 to move, and the four positioning wheels 5 move close to each other, and finally the extrusion and fixing operation of the arc-shaped outer wall of the flange is realized. At this time, since the limiting plate 7 is on the upper end surface of the flange, the vertical limiting of the flange is realized, and its stability when placed on the base 1 is ensured, and the waste generated by the drilling of the flange will fall into the annular groove 9 for collection.

[0027] In this solution, after the vertical screw rod 6 is rotated, the limit plate 7 threadedly mounted thereon will be adjusted up and down, and corresponding adjustments can be made when dealing with flanges of different thicknesses.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
