Description

Technical Field

[0001] The utility model relates to the technical field of clamping tools, and particularly relates to a fixture for processing flange forgings. Background Art

[0002] A flange is also called a flange convex disc or a flange. A flange is a part used for connecting shafts to each other and is used for connecting between pipe ends; there are also flanges used at the inlets and outlets of equipment for connecting between two pieces of equipment, such as a reducer flange. A flange connection or a flange joint refers to a detachable connection formed by connecting a flange, a gasket, and bolts as a set of combined sealing structures. A pipe flange refers to a flange used for piping in a piping device, and when used on equipment, it refers to the inlet and outlet flanges of the equipment. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded connection (threaded connection) flanges, welded flanges, and clamp flanges. Flanges are always used in pairs. Low-pressure pipelines can use threaded flanges, and welded flanges are used for pressures above four kilograms. A sealing gasket is added between two flange discs, and then they are fastened with bolts. Flanges of different pressures have different thicknesses, and the bolts they use are also different. When pumps and valves are connected to pipes, the local parts of these equipment are also made into corresponding flange shapes, which is also called flange connection. Any connecting part that uses bolt connection to close the periphery of two planes is generally called a "flange", such as the connection of a ventilation pipe, and this type of part can be called a "flange part". However, this connection is only a part of a device. For example, when connecting a flange and a pump, it is not appropriate to call the pump a "flange part". Smaller ones such as valves can be called "flange parts".

[0003] The patent specification with the publication number of CN221020461U discloses a clamping tool for polishing and processing flange forgings. By integrating the wing frames and lock blocks for clamping and locking the front and rear end faces of the flange forging and the pressing blocks for pressing and locking on the edge of the flange forging on the same base, it can be switched and used according to different polishing requirements for the end face and edge of the flange forging to fasten different positions of the flange forging, avoiding hindering the polishing work, and at the same time, there is no need to transfer the flange forging between different clamping tools and manually re-lock it, greatly improving the polishing processing efficiency, and solving the problem that different clamping tools are required for fixing when polishing the assembly plane and edge of the current flange forging, resulting in cumbersome operation and reduced processing efficiency.

[0004] However, it is found in the implementation of the related technology that the above technical solution has the following problems: During the use of the above device, since the diameters of flange forgings are different, when it is necessary to clamp flange forgings with different diameters, different fixtures need to be used, and multiple sets of fixtures need to be produced, resulting in waste of resources. Therefore, further improvement is needed. Summary of the Utility Model

[0005] The utility model provides a fixture for processing flange forgings, which solves the problem in the related art that it is not convenient to clamp flange forgings of different sizes and reduces the number of fixtures required.

A telescopic rod 241 is fixedly connected to the upper end of the first extension plate 24. A top block 2411 is fixedly connected to the upper end of the telescopic rod 241. A through groove 24111 is formed through the outer surface of the top block 2411. The first soft pads 22 are used to increase the friction between the bottom plate 1 and the bottom of the flange forging. The telescopic rod 241 is used to push the top plate 25 to move. The first extension plate 24 is used to provide a support point for the telescopic rod 241. The first connecting rods 23 are used to make each group of bottom plates 1 form a whole.

[0026] As Figure 3 As shown, a first extension plate 24 is fixedly connected to the outside of the bottom plate 1. A top plate 25 is arranged above the bottom plate 1. Second connecting rods 26 are fixedly connected to both sides of the top plate 25. One end of the second connecting rod 26 is fixedly connected to another group of top plates 25. Second soft pads 251 are uniformly fixedly connected to one end of the top plate 25. A second extension plate 252 is fixedly connected to the outside of the top plate 25.

The second extension plate 252 is used to provide a support point for the output end of the telescopic rod 241. The second connecting rods 26 are used to make each group of top plates 25 form a whole.

[0027] The working principle and usage instructions of the present utility model are as follows: When it is necessary to perform the work of processing and clamping a flange forging, first, the staff needs to take out the flange forging, and then the staff needs to place the lower end of the flange forging towards the bottom plate 1 so that the flange forging is placed on the upper end of the bottom plate 1. Then, place the end of the second soft pad 251 of the top plate 25 towards the upper end of the flange forging, and align the card slot 2521 with the top block 2411. At this time, pass the threaded rod 21 through the inside of the circular groove 2522 and the through slot 24111 and fixedly connect it to the threaded groove 25211 through threads. At this time, it can prevent the top block 2411 from disengaging from the inside of the card slot 2521. At this time, the telescopic rod 241 can be controlled to expand and contract. Under the action of the threaded rod 21, the telescopic rod 241 drives the second extension plate 252 to move towards the flange forging, and the second extension plate 252 drives the top plate 25 to move towards the flange forging until the first soft pad 22 completely abuts against the lower end of the flange forging and the second soft pad 251 completely abuts against the upper end of the flange forging. At this time, under the action of the bottom plate 1 and the top plate 25, an effective clamping and fixing of the flange forging can be formed. And under the action of the first soft pad 22 and the second soft pad 251, it can further prevent the flange forging from rotating between the bottom plate 1 and the top plate 25. And the first soft pad 22 and the second soft pad 251 can form a certain protection for the upper and lower ends of the flange forging. And because the bottom plate 1 and the top plate 25 have a certain length, the flange forgings with diameters within the range of the bottom plate 1 and the top plate 25 can be effectively fixed to them.

[0028] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
