[0002] A non-circular flange is a flange with a special shape or structure that differs from a regular round flange in terms of appearance, size, connection method, or application. Because non-circular flanges can be customized to any size, they are widely used in large equipment in aerospace, petroleum, chemical, and shipbuilding industries. When it is necessary to drill bolt holes for a non-circular flange, a machining fixture is required to fix the non-circular flange in place to facilitate subsequent processing.

[0003] The prior art patent document CN210412599U provides a clamp for irregular flanges. By setting the clamping plate, the contact surface between the clamping jaws and the irregular flange is increased, thereby improving the clamping and fixing effect of the irregular flange. Furthermore, by setting a fixing plate on one side of the chuck body and a positioning rod thereon, the irregular flange can be positioned without interfering with the machining surface of the irregular flange.

[0004] While the existing technology described above can effectively fix irregular flanges, irregular flanges come in various sizes and thicknesses, and the device cannot fix flanges of different thicknesses and sizes, lacking adaptability and failing to meet people's needs. Therefore, we need a lathe fixture for machining oblique holes in irregular flanges. Utility Model Content

A mounting bearing 303 is provided on the inner wall of the collection trough 301, and a rotating shaft 304 is rotatably connected to the inner wall of the mounting bearing 303. A roller 305 is provided on the outer wall of the rotating shaft 304, and a mounting block 306 is provided at one end of the rotating shaft 304.

[0025] Through the above technical solution, the worker places the concave surface of the irregular flange on the fixing plate 207, moves the clamping arm 206 by rotating the knob 204 to clamp the irregular flange, and presses down the pressure plate 209 by rotating the pressure plate 209, thereby fixing irregular flanges of different sizes and thicknesses, increasing adaptability and meeting people's needs; when processing irregular flanges, a large amount of debris is generated. The debris can fall into the collection box 302 through the slide 201 for collection. When it is necessary to clean the collection box 302, the handle on the collection box 302 can be pulled out. The rollers 305 set in the collection groove 301 can make the collection box 302 move more smoothly when being pulled out and put in.

[0026] Specifically, there are two slides 201, and the two slides 201 are symmetrically arranged on the base 1.

[0027] Through the above technical solution, by setting two sliding grooves 201, the left and right clamping arms 206 can be provided with a moving track and guide, which can drive the clamping arms 206 to move closer to or away from the irregular flange, and clamp or loosen the irregular flange of different sizes.

[0028] Specifically, the inner wall shape and size of the slide 201 match the outer wall shape and size of the movable frame 205, and the inner wall of the slide 201 fits against the outer wall of the movable frame 205.

[0029] With the above technical solution, when the movable frame 205 moves, the movable frame 205 can move more stably in the slide groove 201, avoiding deviation or shaking.

[0030] Specifically, one end of the threaded rod 203 extends into the fixed bearing 202, forming a rotating structure with the fixed bearing 202, and the other end of the threaded rod 203 passes through the base 1 and is connected to the knob 204.

[0031] With the above technical solution, when the operator turns the knob 204, the threaded rod 203 can rotate, and the threaded rod 203 can rotate more stably through the fixed bearing 202.

[0032] Specifically, the outer wall of the positioning rod 208 is threaded, and the thread on the positioning rod 208 matches the thread on the inner wall of the pressure plate 209.

[0033] Through the above technical solution, by rotating the pressure plate 209, the pressure plate 209 can be moved, thereby pressing the non-standard flanges of different thicknesses.

[0034] Specifically, the inner wall shape and size of the collection trough 301 match the outer wall shape and size of the collection box 302, and the inner wall of the collection trough 301 fits into the outer wall of the collection box 302.

[0035] With the above technical solution, when it is necessary to clean the collection tank 301, the handle on the collection tank 301 can be pulled out of the collection box 302, and the collection tank 301 can make the collection box 302 move more stably.

[0036] Specifically, there are multiple rollers 305, and the multiple rollers 305 are symmetrically arranged in the collection groove 301.

[0037] By using the above technical solution, and by setting multiple rollers 305, when the collection tank 301 moves within the collection tank 301, the rollers 305 contact the bottom of the collection box 302, turning sliding friction into rolling friction, allowing operators to more easily and effortlessly pull the collection box 302 out of or push it into the collection tank 301.

[0038] In use, firstly, the operator installs the concave surface of the irregular flange onto the fixed plate 207. Then, they rotate the knob 204, causing the threaded rod 203 to rotate within the fixed bearing 202. As the threaded rod 203 rotates, the moving frame 205 moves, driving the clamping arm 206 to move and clamp the fixed plate 207. Next, the operator installs the pressure plate 209 onto the positioning rod 208. By rotating the pressure plate 209, it presses down, tightly pressing the irregular flange. When processing the irregular flange... The generated debris can fall into the collection box 302 through the chute 201. When it is necessary to clean the debris in the collection box 302, the handle on the collection box 302 can be pulled out of the collection trough 301. The collection trough 301 is provided with multiple rollers 305, which can make the collection box 302 move more smoothly when the collection trough 301 moves within the collection trough 301. This completes all the work. The contents not described in detail in this specification are prior art known to those skilled in the art.
