Description

Technical Field

[0001] This utility model belongs to the field of drilling technology, specifically a CNC drilling and positioning device for flanges. Background Technology

[0002] A flange is an important mechanical accessory used to connect pipes, equipment, or mechanical components. It is usually disc-shaped with holes around its perimeter for fixing. Two flanges are fastened together by bolts to achieve the functions of sealing and connection. Drilling flanges is an important process in flange processing. When drilling with existing flange drilling equipment, workers manually fix and control the flange during drilling, which can easily cause injury to workers. In addition, manual adjustment of the flange angle is prone to deviation, resulting in the failure of flange processing. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a flange CNC drilling and positioning device, which solves the problems of existing flange drilling devices where workers manually fix and control the flange during drilling, which can easily cause injury to workers, and manual adjustment of the flange angle is prone to deviation, resulting in flange processing failure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a CNC drilling and positioning device for a flange, comprising a base, a mounting groove on the top of the base, an intermittent rotating block rotatably mounted at the center of the bottom of the mounting groove via a bearing, a machining seat fixedly mounted on the top of the intermittent rotating block, the machining seat resting on the top of the base, a machining groove on the top of the machining seat, three T-shaped sliding grooves at equal angles on the top of the machining seat located inside the machining groove, a movable stud rotatably connected at the center of the top of the machining seat via a bearing, a connecting block threaded through the surface of the movable stud, three connecting rods rotatably connected at equal angles via pins on the surface of the connecting block, a support block rotatably connected at the end of each connecting rod away from the connecting block via a pin, a T-shaped block fixedly mounted at the bottom of the support block, the T-shaped block slidingly connected to the T-shaped sliding groove, and a flange blank fitted onto the surface of the three support blocks.

[0005] As a further embodiment of this utility model: the bottom of the mounting groove is provided with a placement groove, and a motor is fixedly installed inside the placement groove.

[0006] As a further embodiment of this utility model: a rotating disk is fixedly connected to one output end of the motor, and a rolling block is rotatably connected to one side of the top of the rotating disk through a pin, and the rolling block corresponds to the snap-fit ​​groove on the surface of the intermittent rotating block.

[0007] As a further embodiment of this utility model: a support frame is fixedly installed on one side of the base, and a limiting groove is provided on the top of one side of the support frame.

[0008] As a further embodiment of this utility model: a second motor is fixedly installed on the top of the support frame, and a first bevel gear is fixedly connected to the output end of the second motor, with the second bevel gear meshing on one side of the first bevel gear.

[0009] As a further embodiment of this utility model: a rotating screw is fixedly connected to the bottom of the second bevel gear, and the two ends of the rotating screw are rotatably connected to the inner wall of the limiting slide groove through bearings. A connecting slider is threadedly connected to the surface of the rotating screw located inside the limiting slide groove. A drilling machine is fixedly installed on one side of the connecting slider, and the drilling machine is positioned corresponding to the processing groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This CNC drilling and positioning device for flanges, equipped with a movable stud and a support block, allows the connecting block to rise when the movable stud is rotated. The connecting block then moves one end of a connecting rod upward, while the other end of the connecting rod pulls the support block towards the movable stud, reducing the gap between the three support blocks. The flange blank is then placed on the machining base through the support block. The movable stud is then rotated in the opposite direction to move the connecting block downward, pushing the connecting rod to lift the support block outward until the support block is pressed tightly against the inner ring of the flange blank. This clamps and fixes the flange blank to the top of the machining base, thereby aligning the center of the flange blank with the center of the machining base and preventing misalignment during drilling of the flange blank.

[0012] 2. This CNC drilling and positioning device for flanges, equipped with a rotating disc and intermittent rotating blocks, allows the flange blank to be rotated after one drilling operation to continue drilling the outer ring of the flange blank. The motor is started to drive the rotating disc to rotate. At this time, a rolling block on one side of the rotating disc rotates on the snap-fit ​​groove surface of the intermittent rotating block. The rolling block rotates out of the snap-fit ​​groove of the intermittent rotating block, pushing the intermittent rotating block to rotate. After the rotating disc drives the rolling block to rotate one revolution, it snaps into another snap-fit ​​groove on the surface of the intermittent rotating block, thus stopping the intermittent rotating block at a fixed angle. This, in turn, allows the flange blank to rotate at a fixed angle, improving the quality of the flange blank drilling process. Attached Figure Description

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a CNC drilling and positioning device for a flange, including a base 1, a mounting groove 2 on the top of the base 1, an intermittent rotating block 7 rotatably mounted at the center of the bottom of the mounting groove 2 via a bearing, a machining seat 8 fixedly mounted on the top of the intermittent rotating block 7, and the machining seat 8 resting on the top of the base 1, a machining groove 9 on the top of the machining seat 8, and three T-shaped sliding grooves 15 at equal angles on the top of the machining seat 8 located inside the machining groove 9. By providing the machining groove 9, when the drilling machine 24 drills the flange blank 16, the drill bit of the drilling machine 24 passes through the flange blank 16 and enters the machining groove 9, so that the drilling machine 24 will not damage the machining seat 8.

[0019] A movable stud 10 is rotatably connected to the top center of the machining base 8 via a bearing. A connecting block 11 is threaded through the surface between the movable stud 10 and the machining base 8. Three connecting rods 12 are rotatably connected to the surface of the connecting block 11 via pins, and the positions of the connecting rods 12 correspond to the T-shaped slide groove 15. By providing the movable stud 10, the rotation of the movable stud 10 controls the up and down movement of the connecting block 11, which causes the connecting rods 12 to pull the support block 13 to move, thereby controlling the closing or opening of the support block 13.

[0020] Each connecting rod 12 has a support block 13 rotatably connected to the end away from the connecting block 11 via a pin. A T-shaped block 14 is fixedly installed at the bottom of the support block 13, and the T-shaped block 14 is slidably connected to the T-shaped groove 15. A flange blank 16 is fitted onto the surface of the three support blocks 13. By providing the T-shaped block 14, when the connecting block 11 moves upward and drives the connecting rod 12 to pull the support block 13 to move, the T-shaped block 14 at the bottom of the support block 13 slides in the T-shaped groove 15, so that the support block 13 will not deviate when moving and will not detach from the surface of the machining seat 8.

[0021] The base 1 has a mounting groove 2 at the top and a placement groove 3 at the bottom. A motor 4 is fixedly installed inside the placement groove 3. A rotating disk 5 is fixedly connected to the output end of the motor 4. A rolling block 6 is rotatably connected to one side of the top of the rotating disk 5 via a pin. The rolling block 6 corresponds to the locking groove on the surface of the intermittent rotating block 7. By providing the rolling block 6, when the rolling block 6 makes a circular motion through the rotating disk 5, the rolling block 6 rolls in the locking groove in the intermittent rotating block 7, thereby reducing the friction between the rolling block 6 and the locking groove of the intermittent rotating block 7.

[0022] A support frame 17 is fixedly installed on one side of the base 1. A limiting groove 23 is provided on the top of one side of the support frame 17. A second motor 18 is fixedly installed on the top of the support frame 17. A first bevel gear 19 is fixedly connected to the output end of the second motor 18. A second bevel gear 20 meshes with one side of the first bevel gear 19. By providing the first bevel gear 19, the rotation of the second motor 18 is transmitted to the rotating screw 21 through the meshing of the first bevel gear 19 and the second bevel gear 20. This makes it convenient to control the rotation of the rotating screw 21 to drive the connecting slider 22 to lift and lower the drilling machine 24, thereby making the position of the drilling machine 24 more accurate.

[0023] A rotating screw 21 is fixedly connected to the bottom of the bevel gear 20, and both ends of the rotating screw 21 are rotatably connected to the inner wall of the limiting slide groove 23 through bearings. A connecting slider 22 is threadedly connected to the surface of the rotating screw 21 located inside the limiting slide groove 23. A drilling machine 24 is fixedly installed on one side of the connecting slider 22, and the drilling machine 24 corresponds to the position of the processing groove 9. By providing the connecting slider 22, the connecting slider 22 slides in the limiting slide groove 23 through the rotating screw 21, so that the drilling machine 24 is not easy to deviate when moving, making the drilling process more accurate.

[0024] The working principle of this utility model is as follows:

[0025] Rotating the moving stud 10 raises the connecting block 11, causing the connecting rod 12 to pull the support block 13 towards the moving stud 10, allowing the flange blank 16 to pass through the support block 13 and be placed on the surface of the machining base 8. Then, rotating the moving stud 10 in the opposite direction moves the support block 13 towards the inner ring of the flange blank 16, fixing the flange blank 16 on the top of the machining base 8. Starting the second motor 18 causes the first bevel gear 19 to drive the second bevel gear 20, thereby rotating the rotating screw 21 to control the drilling machine 24 to move downwards to drill the flange blank 16. After drilling is completed, controlling the drilling machine 24 to move upwards and detach from the flange blank 16, starting the first motor 4 to rotate the rotating disk 5 one revolution, thereby causing the intermittent rotating block 7 to drive the machining base 8 to rotate at a fixed angle, adjusting the position of the flange blank 16 to be processed. The drilling machine 24 then drills the flange blank 16 a second time. This process is repeated until the drilling machine 24 completes the drilling of the flange blank 16.
