[0022] Reference Figures 1-3An angle-adjustable flange processing fixture includes a worktable 2. A clamping assembly is provided on the upper surface of the worktable 2. The clamping assembly includes two fixing blocks 3, both of which are bolted to the upper surface of the worktable 2. Each fixing block 3 is threaded with a threaded rod 4. One end of the threaded rod 4 is rotatably connected to a clamping block 1. When a flange is placed between the clamping assemblies, rotating the threaded rod 4 moves the clamping block 1 until it contacts and clamps the flange. An assembly block 13 is mounted on the upper surface of the worktable 2 via a position adjustment assembly. The position adjustment assembly includes a first slide rail 5, which is bolted to the upper surface of the worktable 2. A mounting bracket 10 is slidably connected to the top of the first slide rail 5. The bottom of the mounting bracket 10 is provided with a fixing assembly to restrict its movement. The mounting bracket 10 is moved according to the position of the clamped flange, so that the component connected to its top is moved to the required position. Two guide grooves 11 are provided on one side of the mounting bracket 10. A lifting valve rod 7 is bolted to the bottom of the mounting bracket 10. A lifting platform 8 is bolted to the extended end of the lifting valve rod 7. One end of the lifting platform 8 passes through the guide groove 11 and is bolted to a second slide rail 9. A slide table 22 is slidably connected to one side of the second slide rail 9 and is fixed to the assembly block 13. Fixing screws are threaded to both sides of the slide table 22 and are in contact with the second slide rail 9. By pushing the slide table 22, the slide table 22 is moved along the second slide rail 9 to the required position. At the same time, the components installed on the side of the slide table 22 move along with it. The fixing screws are rotated to ensure tight contact with the second slide rail 9, and the drill bit 14 is then rotated by starting the motor. The lifting valve rod 7 is activated, causing it to retract and move the lifting platform 8 downwards along the guide groove 11. This moves the second slide rail 9 and its connected components downwards to the desired position, allowing the drill bit 14 to move downwards to drill the flange. A connecting frame 15 is mounted on one end of the assembly block 13 via an adjustable-angle connecting assembly. A motor is bolted to the upper surface of the connecting frame 15, and one end of the motor output shaft passes through the connecting frame 15 and is fitted with the drill bit 14. The connecting assembly includes a slide groove 18, which is located inside the assembly block 13. A protruding rod 20 is welded to one side of the connecting frame 15, and the protruding rod 20... The slide groove 18 is inserted into the groove. An annular groove 19 is formed on the outer side of the protruding rod 20. A pull groove 17 is formed on the top of the assembly block 13. A lead rod 12 is threaded into the pull groove 17, and the bottom end of the lead rod 12 passes through the pull groove 17 and engages with the annular groove 19. Multiple slots 16 are formed at one end of the assembly block 13. Multiple insertion rods 21 are welded to one side of the connecting frame 15, and the insertion rods 21 engage with the corresponding slots 16. When the angle of the drill bit 14 needs to be adjusted, the lead rod 12 is rotated to move it out of the annular groove 19. At this time, the protruding rod 20 is no longer restricted. The operator moves the connecting frame 15 to move the insertion rods 21 out of the slots 16, rotates the connecting frame 15 to adjust the angle of the drill bit 14 to the required angle, and then reconnects the connecting frame 15 to the assembly block 13.Insert the insertion rod 21 into the corresponding slot 16, and finally secure it by re-inserting the lead screw 12 into the annular groove 19.

[0023] It should be noted that the fixing components include adjusting screws 6, which are threadedly connected to the bottom of the mounting bracket 10 and contact the upper surface of the first slide rail 5. The mounting bracket 10 is fixed in position by adjusting screws 6. Guide rods are slidably connected inside the two fixing blocks 3, and the guide rods are fixed to the clamping block 1. The guide rods can guide the clamping block 1 so that it can move stably. The lifting platform 8 is slidably connected to the guide groove 11. The guide groove 11 can guide the lifting platform 8 so that it can move stably. Limiting blocks are welded to both ends of the first slide rail 5 and the second slide rail 9 to limit the position of the slide table 22 and the mounting bracket 10.

[0024] Working principle: When a flange needs to be processed, first place the flange between the clamping components, rotate the threaded rod 4 to move the clamping block 1 until it contacts and clamps the flange. Then, move the mounting bracket 10 according to the position of the clamped flange, so that the components connected to its top are moved to the required position. The position of the mounting bracket 10 is fixed by adjusting the screw 6. Then, push the slide table 22 to move it along the second slide rail 9 to the required position. At the same time, the components installed on the side of the slide table 22 move with it and are fixed by rotating the fixing screw to make them tightly contact the second slide rail 9. Then, start the motor to rotate the drill bit 14 and start the lifting air valve rod 7 to raise and lower the air... The valve stem 7 retracts, causing the lifting platform 8 to move downwards along the guide groove 11, thereby moving the second slide rail 9 and the components connected to its end points downwards to the required position. This causes the drill bit 14 to move downwards to drill the flange. When the angle of the drill bit 14 needs to be adjusted, the lead screw 12 is rotated to move it out of the annular groove 19. At this time, the protruding rod 20 is no longer restricted. The operator moves the connecting frame 15 to move the insertion rod 21 out of the slot 16. The connecting frame 15 is rotated to adjust the angle of the drill bit 14 to the required angle. The connecting frame 15 is then reconnected to the assembly block 13 so that the insertion rod 21 is inserted into the corresponding slot 16. Finally, the lead screw 12 is reinserted into the annular groove 19 to achieve fixation.
