[0002] A flange, also called a flange plate or flange, is a part used to connect pipes to each other. It is used for the connection between pipe ends and is also used on the inlet and outlet of equipment. As a key component for connecting pipes, valves and equipment, the processing quality of the flange directly affects the sealing and safety of the entire system.

[0003] Traditional flange fixing fixtures typically fix the flange on only one working surface, which is mostly parallel to the worktable. This limits the machining and observation angles, thus affecting actual machining and use. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an adjustable clamping device for flange processing, which solves the problem that traditional flange fixing clamps basically only fix the flange on one working surface, and most of them are working surfaces parallel to the worktable, which leads to limited processing and observation angles, thus affecting actual processing and use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable flange processing clamping device, including a fixed base, multiple fixed blocks connected to both sides of the fixed base, a connecting rod connected to the fixed base, a deflection table rotatably connected to the fixed base via the connecting rod, a first sliding groove provided on the fixed base, a hydraulic push rod installed on the fixed base, a push plate connected to the movable end of the hydraulic push rod, a first guide groove provided on the push plate, a connecting plate connected to one side below the deflection table, and a motor fixedly installed below the deflection table;

[0006] A second sliding groove is provided below the deflection table, a fixed plate is fixedly installed on the deflection table, a gear plate is rotatably connected below the fixed plate, a placement platform is connected above the fixed plate, a plurality of arc-shaped grooves are provided on the gear plate, a plurality of second guide grooves are provided on the fixed plate, a sliding rod is slidably connected in the arc-shaped grooves and the second guide grooves, a movable strip is connected to one end of the sliding rod, and a tensioning plate is connected to the movable strip.

[0007] As a further embodiment of this utility model: a gear is mounted on the output shaft of the motor, and the gear and the gear disk are rotatably connected in the deflection table, and the gear and the gear disk mesh with each other.

[0008] As a further embodiment of this utility model: the placement platform is provided with multiple limiting grooves, and there are four of each of the arc-shaped groove, the second guide groove and the limiting groove, which are all evenly arranged in a centrally symmetrical manner, and the movable strip slides in the limiting groove.

[0009] As a further embodiment of this utility model: a fixed rod is connected inside the second slide groove, the positions of the first slide groove and the second slide groove correspond to each other, the hydraulic push rod is specifically arranged between the first slide groove and the second slide groove, and the push plate slides inside the first slide groove and the second slide groove.

[0010] As a further embodiment of this utility model: the first guide groove is inclinedly disposed on the push plate, the fixed rod is slidably connected to the first guide groove, and the connecting plate is rotatably connected to the connecting rod.

[0011] As a further embodiment of this utility model: the four fixing blocks are arranged in a rectangular array, and fixing holes are provided on the fixing blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This adjustable flange processing clamping device, by setting up a hydraulic push rod, a push plate, a first slide groove, a second slide groove, a first guide groove, a fixed rod, a connecting rod, and a connecting plate, allows the operator to activate the hydraulic push rod, causing it to push the push plate to slide within the first and second slide grooves. As the push plate moves, the fixed rod slides within the first guide groove, thereby pushing the fixed rod through the inclined first guide groove, causing the connecting plate to rotate on the connecting rod. This adjusts the angle between the deflection table and the fixed seat, changing the working angle of the placement table, thus enabling multi-angle processing and observation of the workpiece flange, improving its practicality.

[0014] 2. This adjustable flange processing clamping device, by setting up a motor, gears, a gear plate, an arc groove, a second guide groove, a sliding rod, a movable bar, and a tensioning plate, allows the operator to start the motor and rotate the gears, causing the gears to mesh with the gear plate and drive the gear plate to rotate. When the gear plate rotates, the arc groove pushes the sliding rod, causing the sliding rod to move along the second guide groove. This causes the sliding rod to drive the movable bar to move along the limiting groove, allowing the tensioning plate to contact the inner ring of the flange, thereby tightening and fixing the flange and preventing the flange from sliding or shifting during actual processing.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: an adjustable clamping device for flange processing, including a fixed base 1, with multiple fixed blocks 2 connected to both sides of the fixed base 1. The four fixed blocks 2 are arranged in a rectangular array. Fixed holes 23 are provided on the fixed blocks 2. By screwing bolts into the fixed holes 23 on the fixed blocks 2, the fixed base 1 can be fixed on the worktable, thereby preventing the fixed base 1 from sliding during processing.

[0023] A connecting rod 3 is connected to a fixed base 1. A deflecting platform 4 is rotatably connected to the fixed base 1 via the connecting rod 3. A first sliding groove 5 is provided on the fixed base 1. A hydraulic push rod 6 is installed on the fixed base 1. A push plate 7 is connected to the movable end of the hydraulic push rod 6. A first guide groove 8 is provided on the push plate 7. The first guide groove 8 is inclined on the push plate 7. A fixed rod 22 is slidably connected to the first guide groove 8. A connecting plate 9 is rotatably connected to the connecting rod 3. Through the inclined first guide groove 8, the fixed rod 22 can gradually move upward along the first guide groove 8 when the push plate 7 moves, thereby pushing the deflecting platform 4 to make the connecting plate 9 rotate on the connecting rod 3, thereby changing the working angle of the deflecting platform 4.

[0024] A connecting plate 9 is connected to one side of the deflection table 4. A motor 10 is fixedly installed below the deflection table 4. A gear 20 is installed on the output shaft of the motor 10. The gear 20 and the gear disk 13 are rotatably connected inside the deflection table 4. The gear 20 and the gear disk 13 mesh with each other. Through the meshing of the gear 20 and the gear disk 13, the first motor 10 can drive the gear 20 to rotate, thereby causing the arc groove 15 to push the sliding rod 17, causing the tensioning plate 19 to move and tighten to fix the flange.

[0025] A second slide groove 11 is provided below the deflection table 4. A fixed rod 22 is connected in the second slide groove 11. The positions of the first slide groove 5 and the second slide groove 11 correspond to each other. The hydraulic push rod 6 is specifically set between the first slide groove 5 and the second slide groove 11. The push plate 7 slides in the first slide groove 5 and the second slide groove 11. Through multiple arc grooves 15, multiple sliding rods 17 can be pushed synchronously when the gear plate 13 rotates, causing multiple movable bars 18 to drive the tensioning plate 19 to move along the limiting groove 21, thereby tightening and fixing the flange in multiple directions and positions.

[0026] A fixed plate 12 is fixedly installed on the deflection table 4. A gear plate 13 is rotatably connected below the fixed plate 12. A placement platform 14 is connected above the fixed plate 12. Multiple arc-shaped grooves 15 are formed on the gear plate 13. Multiple second guide grooves 16 are formed on the fixed plate 12. A sliding rod 17 is slidably connected in the arc-shaped grooves 15 and the second guide grooves 16. A movable bar 18 is connected to one end of the sliding rod 17. A tension plate 19 is connected to the movable bar 18. Multiple limiting grooves 21 are formed on the placement platform 14. There are four arc-shaped grooves 15, four second guide grooves 16, and four limiting grooves 21, and they are all evenly arranged in a centrally symmetrical manner. The movable bar 18 slides in the limiting groove 21. The movement of the movable bar 18 is restricted and guided by the limiting groove 21 to prevent the movable bar 18 from deviating from the tension plate 19 during movement.

[0027] The working principle of this utility model is as follows:

[0028] The operator places the flange on the placement platform 14, then starts the motor 10 to rotate the gear 20. The gear 20 meshes with the gear disc 13, causing the gear disc 13 to rotate. When the gear disc 13 rotates, the arc groove 15 pushes the sliding rod 17, causing the sliding rod 17 to move along the second guide groove 16. This causes the sliding rod 17 to drive the movable strip 18 to move along the limiting groove 21, allowing the tensioning plate 19 to contact the inner ring of the flange, thereby tightening and fixing the flange. Then, by activating the hydraulic push rod 6, the hydraulic push rod 6 pushes the push plate 7 to slide in the first slide groove 5 and the second slide groove 11. As the push plate 7 moves, the fixing rod 22 slides in the first guide groove 8, thereby pushing the fixing rod 22 through the inclined first guide groove 8, causing the connecting plate 9 to rotate on the connecting rod 3, thereby adjusting the angle between the deflection table 4 and the fixed seat 1.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
