Description

Technical Field

[0001] The utility model relates to the field of clamping devices, in particular to a clamping device for flange processing. Background Art

[0002] A flange is a circular flat plate or annular component, usually made of metal material, used to connect the two ends of a pipe. They usually have holes for installing bolts and nuts. A flange clamp is a device used to clamp and limit the flange during flange processing.

[0003] The Chinese patent document with authorization announcement number CN218856755U proposes a flange clamp, including a base, columns are installed on both sides of the top of the base, and a mounting frame is installed on the inner side of the column, a second electric push rod is evenly installed inside the mounting frame, and a clamping plate is installed on the inner side of the second electric push rod, an anti-slip pad is installed on the inner side of the clamping plate, and anti-slip protrusions are evenly installed on the inner side of the anti-slip pad, and a flange body is installed inside the mounting frame inside the anti-slip protrusion.

[0004] In the above application, although the flange bodies of different models and sizes can be clamped and processed, the flange cannot be automatically flipped during the processing, and the staff must manually flip it, which cannot maintain the continuity of the flange processing. Since the flange has processing steps such as welding during processing, this may cause the flange temperature to rise. At this time, manual flipping by the staff may burn the hands, and the flange is heavy, and manual flipping will also consume the staff's physical strength. Utility Model Content

[0005] In view of the problems existing in the background technology, a clamping device for flange processing is proposed.

[0006] The utility model provides a clamping device for flange processing, comprising a base, a clamping assembly arranged above the base for clamping and fixing the flange, a telescopic mechanism arranged at the lower end of the clamping assembly for lifting and lowering the clamping assembly, a translation assembly arranged on the base and connected to the telescopic mechanism for horizontally moving the clamping assembly, and a flipping assembly arranged on the base for flipping the flange.

[0007] Preferably, two groups of translation components are symmetrically arranged with respect to the clamping component.

[0008] Preferably, a through slot is provided on the base; the translation assembly includes a threaded rod rotatably connected to the wall of the through slot; one end of the threaded rod is connected to a driving mechanism 1, and a slider is also threadedly connected thereto; the fixed end of the telescopic mechanism is arranged on the slider.

[0010] Preferably, the clamping plate is L-shaped.

[0011] Preferably, the flip assembly includes a fixed frame arranged on a base; connecting columns are symmetrically rotatably connected on both sides of the fixed frame; one of the connecting columns is connected to a driving mechanism three arranged on the fixed frame; both connecting columns are rotatably connected to bidirectional threaded rods; both bidirectional threaded rods are symmetrically threadedly connected to clamps, and a limit plate is provided at one end of the bidirectional threaded rod, and a driving mechanism four is provided at the other end; a connecting frame is connected between the clamps on both sides.

[0012] Preferably, the connecting frame is in a U-shape.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] (1) The clamping device for flange processing places the flange between two clamping plates by means of the clamping assembly, telescopic mechanism and translation assembly, and then starts the driving mechanism 4 to drive the bidirectional threaded rod to rotate, so that the two clamping plates move toward each other and clamp the flange. Finally, the driving mechanism 3 is started to drive the clamping plates on both sides to flip at the same time, thereby driving the flange to flip. The flange can be automatically flipped, which is convenient for processing both sides of the flange and maintaining the continuity of the flange processing process. At the same time, it avoids the manual flipping of the flange by the staff, thereby avoiding burns to the hands during handling due to overheating of the flange during processing, and also reduces the labor burden of the staff.

[0015] (2) The clamping device for flange processing places the flange on a chassis and then starts the second driving mechanism, so that the second driving mechanism drives the rotating column and the rotating plate to rotate, thereby driving the limit column to slide in the arc groove, and then driving the clamping plate to slide along the slide rail, so that the clamping plate clamps and fixes the flange from the inner ring of the flange, thereby preventing the flange from shaking during the processing, thereby reducing the processing accuracy.

The clamping assembly 2 is arranged above the base 1 to clamp and fix the flange. The telescopic mechanism 3 is arranged at the lower end of the clamping assembly 2 to lift the clamping assembly 2, and the telescopic mechanism 3 is a cylinder. The translation assembly 4 is arranged on the base 1 and connected to the telescopic mechanism 3 to horizontally move the clamping assembly 2. The flipping assembly 5 is arranged on the base 1 to flip the flange.

[0023] Further explanation, the flipping assembly 5 includes a fixed frame 51 arranged on the base 1; connecting columns 52 are symmetrically and rotatably connected to both sides of the fixed frame 51; a drive mechanism III 57 arranged on the fixed frame 51 is connected to one of the connecting columns 52, and the drive mechanism III 57 is a motor; bidirectional threaded rods 53 are rotatably connected to both connecting columns 52; clamping plates 56 are symmetrically and threadedly connected to both bidirectional threaded rods 53, and a limit plate 54 is arranged at one end of each bidirectional threaded rod 53, and a drive mechanism IV 55 is arranged at the other end, and the drive mechanism IV 55 is a motor; a connecting frame 58 is connected between the clamping plates 56 on both sides. The flange can be flipped, which is convenient for processing both sides of the flange and maintains the continuity of the flange processing process. At the same time, it avoids manual flipping of the flange by the staff, thereby avoiding scalding the hands during handling due to overheating of the flange during processing, and also reducing the labor burden of the staff.

[0024] Further explanation, the connecting frame 58 is in a U-shaped shape. It can adapt to flanges with convex middle parts and increases the application range of the clamping device.

[0025] Embodiment 2

[0026] like Figure 3-4 As shown, the clamping device for flange processing proposed by the present invention, compared with the first embodiment, further comprises: two groups of translation components 4 are symmetrically arranged about the clamping component 2, so that the clamping component 2 moves more smoothly.

[0027] Further explanation, the base 1 is provided with a through slot 41; the translation assembly 4 includes a threaded rod 42 rotatably connected to the wall of the through slot 41; one end of the threaded rod 42 is connected to a driving mechanism 1 43, which is a motor, and a slider 44 is also threadedly connected thereto; the fixed end of the telescopic mechanism 3 is arranged on the slider 44. The clamping assembly 2 can be removed to make room for the flip assembly 5 to flip the flange.

[0028] Further explanation, the telescopic end of the telescopic mechanism 3 is connected to the chassis 21; the upper end of the chassis 21 is provided with a plurality of slide rails 22 in an annular array; the plurality of slide rails 22 are all slidably connected with clamping plates 23; the ends of the plurality of clamping plates 23 close to the center axis of the array are all connected with limiting posts 24; the chassis 21 is also rotatably connected with a rotating post 25; the rotating post 25 is arranged on the center axis of the array of the plurality of slide rails 22, the lower end of the rotating post 25 passes through the chassis 21 and is connected with a second driving mechanism 26, the second driving mechanism 26 is a motor, and the upper end is connected with a rotating plate 27; the rotating plate 27 is provided with arc grooves 28 corresponding to the limiting posts 24 one by one; the arc grooves 28 are arranged in an annular array about the rotating posts 25; the limiting posts 24 are slidably connected at the corresponding arc grooves 28. The flange can be clamped and fixed from the inner ring of the flange to prevent the flange from shaking during the processing, thereby reducing the processing accuracy.

[0029] Further explanation: the clamping plate 23 is L-shaped, which increases the contact area between the clamping plate 23 and the flange, making the clamping of the flange by the clamping plate 23 more stable.

[0030] The working principle of the utility model is as follows: when working, the flange is first placed on the chassis 21, and then the driving mechanism 26 is started, so that the driving mechanism 26 drives the rotating column 25 and the rotating plate 27 to rotate, thereby driving the limiting column 24 to slide in the arc groove 28, and then drives the clamping plate 23 to slide along the slide rail 22, so that the clamping plate 23 clamps and fixes the flange from the inner ring of the flange, and then the flange is processed.

[0031] When one side of the flange is processed and the flange needs to be turned over to process the other side, the telescopic mechanism 3 is first started, so that the telescopic end of the telescopic mechanism 3 extends to drive the clamping assembly 2 to lift, and the flange is lifted to the height between the two clamping plates 56. Then the driving mechanism 1 43 is started to drive the threaded rod 42 to rotate, thereby driving the slider 44 to move along the threaded rod 42 and move the clamping assembly 2 to between the two clamping plates 56. Then the telescopic mechanism 3 drives the clamping assembly 2 to descend, and the translation assembly 4 drives the clamping assembly 2 to move away to make room for the flange to flip. Then the driving mechanism 4 55 is started to drive the bidirectional threaded rod 53 to rotate, so that the two clamping plates 56 move toward each other and clamp the flange. Finally, the driving mechanism 3 57 is started to drive the clamping plates 56 on both sides to flip at the same time, thereby driving the flange to flip. After the flip is completed, the clamping assembly 2 clamps the flange and continues the processing.

[0032] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
