[0002] During the drilling and tapping process of the flange, it is necessary to use a turning tool on a lathe to cut the cut steel plate into flange blanks of the required size, and then perform drilling and punching operations.

[0003] When drilling and tapping the flange on a lathe, the flange blank needs to be fixed by a tooling to center the flange blank to facilitate the accuracy of the flange blank processing. In the existing technology, when processing the flange blank, the flange blank is first clamped, and then one end of the flange blank is processed. After the processing is completed, the flange blank is flipped and clamped, and the other end of the flange blank is processed. At this time, the flange blank needs to be repositioned, and its positioning relies on manual positioning, and it cannot be guaranteed that it is consistent with the first positioning, which affects the processing accuracy. Therefore, we propose a large-diameter flange self-centering drilling and tapping integrated tooling. Utility Model Content

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] The embodiment of the present application provides a large-diameter flange self-centering drilling and tapping integrated tooling, which solves the problem of flipping and clamping the flange blank and processing the other end of the flange blank. At this time, the flange blank needs to be re-positioned, and its positioning relies on manual positioning, which cannot be guaranteed to be consistent with the first positioning, thereby affecting the processing accuracy. The sliding seat 203 is adjusted to slide on the mounting frame 1, driving the sliding seat 203 and the clamping seat 202 to move, which is convenient for positioning flanges of different sizes. Then, by adjusting the distance between the clamping seat 202 and the connecting seat 201, the flange is finely adjusted, and the flange blank is adjusted to the center position, thereby improving the processing accuracy.

[0025] When the flange blank needs to be flipped, clamped and positioned, the rotating seat 303 is adjusted to slide, driving the rotating rod 302 to rotate. Under the rotation of the rotating rod 302, multiple connecting rods 301 move at the same time, driving the sliding seat 203 to move. At this time, multiple sliding seats 203 move at equal distances, driving the connecting seat 201 and the clamping seat 202 to move, which is used to clamp the flange blank so that the flange blank is positioned in the center position, avoiding the need to readjust the positioning later.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] The embodiment of the utility model discloses a self-centering drilling and tapping integrated tool for a large-diameter flange.

[0028] According to the attached Figure 1-4 As shown, it includes a mounting frame 1, a clamping mechanism 2 and an adjusting mechanism 3. The clamping mechanism 2 is arranged on the front of the mounting frame 1, and the adjusting mechanism 3 is arranged on the back of the mounting frame 1.

[0029] The clamping mechanism 2 includes a connecting seat 201 and a clamping seat 202 which are slidably connected to the mounting frame 1. The bottom end surface of the connecting seat 201 is fixedly connected to a sliding seat 203. The sliding seat 203 is slidably connected to the inner wall of the mounting frame 1. The sliding seat 203 is adjusted to slide on the mounting frame 1, driving the sliding seat 203 and the clamping seat 202 to move, so as to facilitate the positioning of flanges of different sizes. The flange can be finely adjusted by adjusting the distance between the clamping seat 202 and the connecting seat 201, so that the flange blank is adjusted to the center position, thereby improving the processing accuracy.

[0030] The adjusting mechanism 3 includes a connecting rod 301 fixedly connected to the sliding seat 203, and two rotating rods 302 are rotatably connected to the outer wall of the connecting rod 301. When the flange blank needs to be flipped, clamped and positioned, the rotating seat 303 is adjusted to slide, driving the rotating rod 302 to rotate. Under the rotation of the rotating rod 302, multiple connecting rods 301 move at the same time, driving the sliding seat 203 to move. At this time, multiple sliding seats 203 move at equal distances, driving the connecting seat 201 and the clamping seat 202 to move, which is used to clamp the flange blank so that the flange blank is positioned in the center position, avoiding the need to readjust the positioning later.

[0031] A plurality of sliding rods 204 are fixedly connected to the outer wall of the connecting seat 201 , and the sliding rods 204 are slidably connected to the inner wall of the clamping seat 202 . Under the action of the sliding rods 204 , the movement of the clamping seat 202 and the connecting seat 201 is more stable.

[0032] An adjusting screw 205 is rotatably connected to the outer wall of the sliding rod 204, and the adjusting screw 205 is threadedly connected to the inner wall of the clamping seat 202. By rotating the adjusting screw 205, the clamping seat 202 rotates along the outer peripheral wall of the adjusting screw 205. At this time, the adjusting screw 205 slides along the outer peripheral wall of the sliding rod 204. At this time, the distance between the clamping seat 202 and the connecting seat 201 is changed, so that the clamping seat 202 contacts and squeezes the flange blank, thereby positioning the flange blank.

[0033] A bolt is rotatably connected to the inner wall of the connecting seat 201, and the bolt is threadedly connected to the sliding seat 203. The end of the bolt fits against the inner wall of the mounting frame 1. By rotating the bolt, the bolt contacts the mounting frame 1, and at this time, the sliding seat 203 and the mounting frame 1 are restricted, thereby limiting the positions of the connecting seat 201 and the clamping seat 202.

[0034] A slide groove 4 is provided on the mounting frame 1 .

[0035] A moving seat 304 is slidably connected to the inner wall of the sliding groove 4 , and a rotating seat 303 is fixedly connected to the outer wall of the moving seat 304 . The rotating seat 303 is rotatably connected to the corresponding two rotating rods 302 .

[0036] The two rotating rods 302 are rotatably connected to the adjacent connecting rods 301 respectively. When the positions of the multiple connecting seats 201 and the clamping seats 202 need to be adjusted, one of the connecting rods 301 is first pulled to move. As the connecting rod 301 moves, the rotating rod 302 rotates accordingly. At this time, the rotating rod 302 drives the rotating seat 303 to move. At this time, the rotating seat 303 drives the moving seat 304 to slide on the inner wall of the slide groove 4.

[0037] Under the action of the chute 4, the movement path of the rotating seat 303 is limited, and the rotation angle of the rotating rod 302 is the same, so that the rotating rod 302 pushes the adjacent connecting rods 301 to move, and the movement distance of multiple connecting rods 301 is the same;

[0038] When the connecting rod 301 moves, it drives the sliding seat 203 to slide on the inner wall of the mounting frame 1 . At this time, the sliding seat 203 drives the connecting seat 201 to slide, and then performs preliminary adjustment to clamp the flange between the multiple clamping seats 202 .

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
