[0002] Flange, also known as flange flange or flange, is a part that connects pipes to each other. It is used for connection between pipe ends. It is also used as flange on equipment inlet and outlet, used for connection between two devices, such as reducer flange. Flange connection or flange joint refers to a detachable combination of flange, gasket and bolts connected to each other as a sealing structure.

[0003] Traditional flange processing fixtures may not provide uniform clamping force during the clamping process, causing some parts of the workpiece to be subjected to more force, resulting in damage, causing the workpiece to be scrapped and unusable. At the same time, some workpieces have irregular shapes and are difficult to clamp stably in traditional fixtures, so they are prone to deviation.

[0004] Therefore, those skilled in the art provide an adjustable flange processing fixture to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an adjustable flange processing clamp, which uses a rotating rod to drive a threaded column to rotate, thereby causing a gear to rotate, and the gear drives a rotating disk to rotate so that a groove provided at the top of the rotating disk drives a moving column to move, thereby allowing a clamping block to clamp the workpiece. The process of clamping the clamping block using the gear to drive the clamping block in conjunction with the groove can prevent the moving column from slipping during the clamping process, causing the workpiece to deviate, thereby affecting the processing accuracy.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An adjustable flange processing fixture comprises a chassis, the inner bottom of the chassis is provided with a circle of sliding grooves, the inner bottom of the sliding groove is rotatably provided with a sliding ring, the top of the sliding ring is fixedly provided with a gear, a rotating rod is rotatably provided inside the side end of the chassis, a rotating nut is fixedly provided at one end of the rotating rod, and a threaded column is fixedly provided on the outer side of the rotating rod;

[0008] Through the above technical solution, the sliding ring can be used to limit the gear, so that the gear has better stability when in use, and the threaded column can be installed to facilitate the control of the gear and the control of the clamping and loosening.

[0009] Furthermore, a fixing column is fixedly provided at the inner end of the gear, and a rotating disk is fixedly provided at the top end of the fixing column;

[0011] Furthermore, a limited sliding groove is provided at the inner side end of the chassis, and a limited ring is fixedly provided at the outer side of the rotating disk;

[0012] Through the above technical solution, a slide groove is opened on the inner end of the chassis and used in conjunction with the limiting ring on the outer side of the rotating disk, so that the rotating disk can be limited and the rotating disk can be used stably.

[0013] Furthermore, a fixing ring is fixedly provided at the top of the chassis, and a fixing plate is fixedly provided at the top of the fixing ring;

[0014] Through the above technical solution, the use of the fixing ring can leave enough usable space between the fixing plate and the fixing ring, and the fixing plate can be used to limit the movable column.

[0015] Furthermore, a plurality of grooves are provided at the top of the rotating disk, and a plurality of limiting grooves are provided inside the fixed disk;

[0016] Through the above technical solution, a groove is opened at the top of the rotating disk, so that the groove can drive the moving column to move, which can prevent the moving rod from being unable to move when the rotating disk rotates, thereby causing deviation when the workpiece is clamped.

[0017] Furthermore, a plurality of movable columns are slidably disposed on the inner bottoms of the grooves, and a plurality of limit blocks are fixedly disposed on the outer sides of the movable columns;

[0018] Through the above technical solution, the movable column is installed inside the groove to drive the clamping block to clamp the workpiece, and the use of the limit block in conjunction with the limit groove can make the movable column have good stability.

[0019] Furthermore, a clamping block is fixedly provided on the top of each of the plurality of movable columns;

[0020] Through the above technical solution, a clamping block is installed on the top of the moving column, so that the clamping block can clamp the workpiece when the moving column moves.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes an adjustable flange processing fixture, in which a sliding groove is provided on the chassis and a sliding ring is installed inside the sliding groove to connect the sliding ring with the gear. When the gear rotates, the sliding ring will rotate inside the sliding groove, so that the gear can be limited, so that the gear has better stability when in use, and a threaded column is installed on the outer side of a rotating rod for use. When the rotating rod is in use, the gear can be conveniently controlled, so that the clamping and loosening of the fixture can be controlled, and a rotating nut is installed at one end of the rotating rod to facilitate the use of the rotating rod.

[0023] 2. The utility model proposes an adjustable flange processing fixture, which connects the gear with the rotating disk by using a fixed column. When the rotating rod is used to rotate the gear, the rotating disk can be rotated. When the rotating disk is rotating, the restriction of the movable column by the groove can make the movable column move inside the groove, so that the clamping block can be controlled to clamp or release the fixture, and a limit block is installed on the outer side of the movable column for use with the limit groove, so that the movable column can have better stability when rotating, avoiding the clamping block from being unable to clamp the workpiece.

The sliding ring 2 can be used to limit the gear 3, so that the gear 3 has better stability when in use, and the threaded column 6 can be installed for use to conveniently control the gear 3 and control the clamping and loosening of the fixture.

[0034] The inner end of the gear 3 is fixedly provided with a fixing column 7, and the top of the fixing column 7 is fixedly provided with a rotating disk 8. The fixing column 7 is connected with the rotating disk 8 to facilitate the fixing of the rotating disk 8. When the gear 3 rotates, the rotating disk 8 can be rotated along with it. A limited sliding groove 9 is provided on the inner end of the chassis 1, and a limited ring 10 is fixedly provided on the outer side of the rotating disk 8. The sliding groove is provided on the inner end of the chassis 1 and is used in conjunction with the limiting ring 10 on the outer side of the rotating disk 8. The rotating disk 8 can be limited and the rotating disk 8 can be used stably. A fixing ring 11 is fixedly provided on the top of the chassis 1, and a fixing disk 12 is fixedly provided on the top of the fixing ring 11. The fixing ring 11 can leave enough space for use between the fixing disk 12 and the fixing ring 11, and the fixing disk 12 can be used to limit the movable column 15. A plurality of grooves 13 are provided, and a plurality of limit grooves 14 are provided inside the fixed disk 12. The grooves 13 are provided at the top of the rotating disk 8, so that the grooves 13 can drive the moving column 15 to move, and can prevent the moving rod from being unable to move when the rotating disk 8 is rotating, thereby causing deviation when the workpiece is clamped. Moving columns 15 are slidably provided at the inner bottoms of the plurality of grooves 13, and limit blocks 16 are fixedly provided on the outer sides of the plurality of moving columns 15. The moving columns 15 are installed inside the grooves 13 to drive the clamping blocks 17 to clamp the workpiece, and the limit blocks 16 are used in conjunction with the limit grooves 14 to give the moving columns 15 good stability. The clamping blocks 17 are fixedly provided at the tops of the plurality of moving columns 15, and the clamping blocks 17 are installed at the tops of the moving columns 15, so that the clamping blocks 17 can clamp the workpiece when the moving columns 15 move.

[0035] Working principle: when in use, the rotating nut 5 is turned to rotate the rotating rod 4, so that the rotating rod 4 drives the threaded column 6 to rotate. Since the threaded column 6 is meshed with the gear 3, rotating the rotating rod 4 will cause the gear 3 to drive the fixed column 7 to rotate, and the fixed column 7 drives the rotating disk 8 to rotate. When the rotating disk 8 rotates, the groove 13 limits the movable column 15, so that the movable column 15 can move in the groove 13. When moving, the limit block 16 on the outside of the movable column 15 is used in conjunction with the limit groove 14 provided inside the fixed disk 12 to limit the movable column 15, so that the movable column 15 has better stability when driving the clamping block 17 to clamp. When the clamp needs to loosen the workpiece, it only needs to use the rotating nut 5 to reverse the threaded column 6, so that the movable column 15 can be reversed, so that the clamping block 17 can loosen the workpiece.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
