Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, and in particular to a flange drilling device. Background Technology

[0002] An existing metal flange drilling device (publication number CN 219724644 U) involves placing the flange to be processed on a mounting base, then rotating an adjustment knob forward. This adjustment, in conjunction with the power assembly, causes two rotating rods to rotate synchronously and in opposite directions around a fixed lug. The synchronous rotation of the two rotating rods drives two clamping members to move in opposite directions, clamping and fixing the flange. A telescopic drilling mechanism then drills a hole in the flange. After drilling is complete, rotating the adjustment knob in reverse causes the rotating rods to move the two clamping members away from each other, thus releasing the clamping mechanism and allowing the flange to be removed. However, this device, when clamping and fixing the flange, involves numerous transmission structures such as gears, racks, slide bars, rotating rods, and movable rods, resulting in a complex operation and inconvenience for users.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-5 As shown, a flange drilling device includes a drilling body 1, which is a radial arm bench drill, which is prior art and will not be described in detail here. A clamping mechanism for clamping and fixing the flange is installed on the worktable of the drilling body 1.

[0024] In this embodiment: the clamping mechanism includes a support assembly, a rotating assembly is provided on the support assembly, and a clamping assembly is provided on the rotating assembly that moves simultaneously with the flange placed on the inner side during rotation;

[0025] The support assembly includes a mounting bracket 21 mounted on a workbench, with a support column and a support base 28 at the upper end of the mounting bracket 21. The rotating assembly includes a base 22 fixed to the upper end of the support column, with four first vertical grooves 221 evenly distributed around the circumference of the base 22. A top plate 27 is connected to the upper end of the base 22, and a second vertical groove 271 opposite to the first vertical grooves 221 is formed on the top plate 27. A rotating disk 23 is disposed between the base 22 and the top plate 27, with four arc-shaped through grooves evenly distributed around the circumference of the rotating disk 23. 231. A worm gear ring 24 is fixedly installed on the outer ring of the rotating disk 23. A worm 29 that meshes with the worm gear ring 24 is installed on the support 28. The clamping assembly passes through the first vertical groove 221, the arc-shaped through groove 231 and the second vertical groove 271. The base 22 and the top disk 27 are fixedly connected. The rotating disk 23 is rotatably connected to the base 22 and the top disk 27. The worm 29 is rotatably connected to the support 28. A protective plate 210 is installed on the support 28 to protect the meshing point between the worm 29 and the worm gear ring 24.

[0026] The clamping assembly includes an adjusting rod 25, which passes through an arc-shaped through groove 231 and a second vertical groove 271. The lower end of the adjusting rod 25 is square-column shaped, and the upper side is cylindrical. A clamping seat 26 is fixed to the upper end of the adjusting rod 25.

[0027] The working principle and usage process of this utility model are as follows: The flange is placed on the top plate 27. By rotating the worm gear 29, the worm gear 29 meshes with the worm wheel ring 24 and rotates, driving the rotating disk 23 to rotate. During the rotation, the arc-shaped through groove 231 on the rotating disk 23 causes the adjusting rod 25 to move towards the center position under the limitation of the first vertical groove 221 on the base plate 22 and the second vertical groove 271 on the top plate 27. This causes the clamping seat 26 to clamp and fix the outer ring of the flange at the center. Then, the drilling body 1 performs drilling operations on the fixed flange.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
