Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a clamp for fixing flanges. Background Art

[0002] During the production and processing of flanges, fixtures are required to fix them to facilitate processing quality inspections of flanges, such as ultrasonic flaw detection and impact resistance tests.

[0003] Most existing flange fixing fixtures fix the flange by clamping the outer edge. If the flange is subjected to external force, the flange may move, causing the position to change, affecting the quality inspection effect of the flange processing. Utility Model Content

[0004] The utility model aims to solve the defect in the prior art that flange clamps only clamp the outer edge, and proposes a clamp for fixing the flange.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A clamp for fixing a flange, comprising a mounting shell, wherein both side outer walls of the mounting shell are fixedly connected to a first motor, an output end of the first motor is keyed to a first screw rod, a first clamping plate is provided on a threaded sleeve on the outer wall of the first screw rod, both side outer walls of the mounting shell are fixedly connected to a second motor, an output end of the second motor is keyed to a second screw rod, a second clamping plate is provided on a threaded sleeve on the outer wall of the second screw rod, the top end of the second clamping plate is fixedly connected to a top plate, a threaded rod is inserted into the top thread of the top plate, and a pressure plate is rotatably connected to the bottom end of the threaded rod, and two sliding grooves are provided on the top of the mounting shell, and the first clamping plate and the second clamping plate slide in the sliding grooves.

[0007] Furthermore, mounting holes are provided on both sides of the mounting shell.

[0008] Furthermore, a buffer pad is bonded to one side of the first plywood and one side of the second plywood.

[0009] Furthermore, a non-slip pad is bonded to the bottom of the pressing plate.

[0010] Furthermore, a knob is fixedly connected to the top end of the threaded rod.

[0011] The beneficial effects of the utility model are:

[0012] 1. The first clamping plate is moved by the first motor to tighten the flange from the inside. Then, the second clamping plate is moved by the second motor to clamp the flange from the outside. The threaded rod pressure plate is then screwed onto the flange to stably fix the flange and prevent it from moving during processing.

[0013] 2. The anti-slip pad increases the friction between the pressure plate and the flange, improving the stability of the flange fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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 the embodiments.

[0019] Reference Figure 1-Figure 3 , a fixture for fixing a flange, comprising a mounting shell 1, the outer walls of both sides of the mounting shell 1 are fixed with a first motor 4 by bolts, the output end of the first motor 4 is keyed to a first screw rod 5, the outer wall of the first screw rod 5 is threadedly sleeved with a first clamping plate 6, the first screw rod 5 is rotated under the drive of the first motor 4, thereby driving the first clamping plate 6 to move, and then tensioning from the inside of the flange, the outer walls of the mounting shell 1 are fixed with a second motor 8 by bolts, the output end of the second motor 8 is keyed to a second screw rod 9, the outer wall of the second screw rod 9 is threadedly sleeved with a first clamping plate 6, and the first screw rod 5 is rotated under the drive of the first motor 4, thereby driving the first clamping plate 6 to move, and then tensioning from the inside of the flange, The threaded sleeve is provided with a second clamping plate 10. The second screw rod 9 is driven by the second motor 8 to rotate, thereby driving the second clamping plate 10 to move, and then clamping from the outside of the flange. A top plate 11 is welded to the top of the second clamping plate 10. A threaded rod 12 is inserted into the top of the top plate 11. The bottom end of the threaded rod 12 is rotatably connected to a pressure plate 13. The threaded rod 12 is screwed to drive the pressure plate 13 to move downward, thereby pressing the pressure plate 13 on the flange. Two slide grooves 3 are provided on the top of the mounting shell 1, and the first clamping plate 6 and the second clamping plate 10 slide in the slide groove 3.

[0020] Mounting holes 2 are provided on both sides of the mounting shell 1 to facilitate the fixed installation of the mounting shell 1. Buffer pads 7 are bonded to one side of the first plywood 6 and one side of the second plywood 10. The buffer pads 7 reduce the force of the first plywood 6 and the second plywood 10 fixing the flange to avoid damage to the flange. An anti-slip pad 14 is bonded to the bottom of the pressure plate 13. The anti-slip pad 14 increases the friction between the pressure plate 13 and the flange, thereby improving the stability of the flange fixation. A knob is welded to the top of the threaded rod 12.

[0021] Working principle: When in use, first, place the flange on the top of the mounting shell 1, and insert the two first clamping plates 6 into the large hole of the flange. Then, the first screw rod 5 is rotated by the drive of the first motor 4, thereby driving the first clamping plate 6 to move, and then tightening from the inside of the flange. Then, the second screw rod 9 is rotated by the drive of the second motor 8, thereby driving the second clamping plate 10 to move, and then clamping from the outside of the flange. Then, turn the knob to drive the threaded rod 12 to rotate, thereby driving the pressure plate 13 to move downward, and then the pressure plate 13 is pressed on the flange, thereby better fixing the flange.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
