[0034] Reference Figure 1 As shown, this utility model provides a technical solution: a precision and efficient pipe bending cutting fixture, comprising:

[0035] The bend body 4 has an "L" shaped cross section.

[0036] Support frame 1, with a worktable 2 fixedly connected to its upper surface; and

[0037] The pipe bending positioning mechanism 3 is located on the worktable 2.

[0038] The following section will explain the specific setup and function of the pipe bending positioning mechanism 3.

[0039] Reference Figures 2 to 6 As shown in this embodiment: the pipe bending positioning mechanism 3 includes a fixed base 301 and two rectangular tubes 306. The lower surface of the fixed base 301 is fixedly connected to the upper surface of the workbench 2. A connecting plate 302 is rotatably connected to the inner wall of the fixed base 301. A sliding hole 303 is provided on the upper surface of the fixed base 301. The center of the sliding hole 303 is coaxial with the axis of rotation of the connecting plate 302. A sliding rod 304 is slidably connected to the inner wall of the sliding hole 303. The lower end of the sliding rod 304 is fixedly connected to the upper surface of the connecting plate 302. An adjusting ring 305 is threadedly connected to the arc surface of the sliding rod 304. One side of the fixed base 301 and one side of the connecting plate 302 are respectively fixedly connected to the two rectangular tubes 306. A rectangular plate 307 is slidably connected to the inner wall of the rectangular tubes 306. The rectangular plate 307 is away from the rectangular tubes. An adjusting plate 308 is fixedly connected to one side of the rectangular tube 306, and a fixing plate 309 is fixedly connected to one side of the outer wall of the rectangular tube 306. A lead screw 310 is rotatably connected to one side of the fixing plate 309, and a connecting plate 311 is threadedly connected to the arc surface of the lead screw 310. One side of the connecting plate 311 is fixedly connected to the side of the adjusting plate 308 near the rectangular plate 307. The side of the bent tube body 4 is respectively attached to the fixing seat 301, the connecting plate 302 and the two adjusting plates 308. By setting the bent tube positioning mechanism 3, the personnel can adjust the position of the adjusting plate 308, the connecting plate 302 and the fixing seat 301 according to the bending angle and length of the bent tube body 4, so as to clamp and position the bent tube body 4 of different models and different bending angles, thereby improving the applicability of the cutting fixture.

[0040] A driven bevel gear 312 is fixedly connected to the arc surface of the lead screw 310. A limit bolt 313 is fixedly connected to the side of the fixing plate 309 near the lead screw 310. A rotating rod 314 is rotatably connected to the inner wall of the limit bolt 313. A driving bevel gear 315 is fixedly connected to the lower end of the rotating rod 314. The driving bevel gear 315 meshes with the driven bevel gear 312. When it is necessary to control the rotation of the lead screw 310, the rotating rod 314 is rotated first to drive the driving bevel gear 315 to rotate. The driving bevel gear 315 drives the driven bevel gear 312 to rotate. The driven bevel gear 312 drives the lead screw 310 to rotate. By setting the above structure, the effect of conveniently controlling the rotation of the lead screw 310 is achieved.

[0041] A rotating block 316 is fixedly connected to the upper end of the rotating rod 314. Rotating the rotating block 316 can drive the rotating rod 314 to rotate, thus achieving the effect of conveniently controlling the rotating rod 314.

[0042] A rubber pad 322 is fixedly connected to the side of the adjusting ring 305 near the fixed seat 301. The diameter of the rubber pad 322 is larger than the diameter of the adjusting ring 305. The rubber pad 322 can increase the friction of the side of the adjusting ring 305 near the fixed seat 301, so that the adjusting ring 305 can be firmly abutted against the fixed seat 301 with the help of the rubber pad 322.

[0043] The pipe bending positioning mechanism 3 also includes three support platforms 317. A fixed frame 318 is fixedly connected to the upper surface of the support platform 317. A nut 320 is rotatably connected to the upper surface of the fixed frame 318. A screw 319 is threadedly connected to the inner wall of the nut 320. A clamping block 321 is fixedly connected to the lower end of the screw 319. When the clamping block 321 is needed to clamp and position the pipe bending body 4 on the workbench 2, the nut 320 is rotated to drive the lead screw 310, so that the lead screw 310 drives the clamping block 321 to move closer to the pipe bending body 4. When the clamping block 321 abuts against the pipe bending body 4, the abutment completes the positioning of the pipe bending body 4. The three clamping blocks 321 are used to position one bend and two bends of the pipe bending body 4, respectively.

[0044] The upper surface of the workbench 2 has several screw holes 323. The support platform 317 is detachably connected to the upper surface of the workbench 2 via the screw holes 323 and bolts. The support platform 317 can be bolted to different positions on the workbench 2 via the screw holes 323, thereby enabling the clamping block 321 on the support platform 317 to position different positions of different bent pipe bodies 4, further improving the applicability of the cutting fixture. The clamping block 321 is frustum-shaped.

[0045] When the cutting fixture is needed to position the bent pipe body 4, first rotate the adjusting ring 305 to move it away from the fixed seat 301 along the arc surface of the slide rod 304. When the adjusting ring 305 causes the rubber pad 322 to separate from the fixed seat 301, the limiting position on the connecting plate 302 can be released. Then, rotate the connecting plate 302 to drive one of the adjusting plates 308 to rotate. When the angle between the connecting plate 302 and the fixed seat 301 matches the angle of the bent section of the bent pipe body 4 to be cut, stop the rotation of the connecting plate 302. Then, rotate the adjusting ring 305 to drive the rubber pad 322 to rotate. The rubber pad 322 abuts against the fixed base 301, thereby fixing the relative position of the connecting plate 302 and the fixed base 301. After the connecting plate 302 is firmly fixed, the two rotating blocks 316 are rotated respectively. The rotating blocks 316 drive the rotating rod 314 to rotate, the rotating rod 314 drives the driving bevel gear 315 to rotate, the driving bevel gear 315 drives the driven bevel gear 312 to rotate, the driven bevel gear 312 drives the lead screw 310 to rotate, and the lead screw 310 drives the connecting plate 311 to move along its arc surface. The connecting plate 311 drives the adjusting plate 3... 08. Simultaneously, the adjusting plate 308 will drive the rectangular plate 307 to move along the inner wall of the rectangular tube 306. After the adjusting plate 308 moves to the appropriate position, the bent tube body 4 is placed on the worktable 2, so that the side of the bent tube body 4 is in contact with the fixed seat 301, the connecting plate 302 and the two adjusting plates 308. Finally, the nut 320 is rotated to drive the screw 319. The screw 319 drives the clamping block 321 to abut against the upper surface of the bent tube body 4. At this time, the clamping and positioning of the bent tube body 4 can be completed. After the bent tube body 4 is cut and processed, the nut 320 is rotated to drive the clamping block. Separate 321 from the bend body 4, and then remove the bend body 4 from the workbench 2. The rubber pad 322 can increase the friction of the adjusting ring 305 near the fixed seat 301, so that the adjusting ring 305 can be firmly abutted against the fixed seat 301 with the help of the rubber pad 322. In addition, the support table 317 can be bolted to different positions on the workbench 2 with the help of the screw hole 323, so that the clamping block 321 on the support table 317 can position different positions of different bend bodies 4, further improving the applicability of the cutting fixture.

[0046] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described.
