Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical manufacturing and processing, and specifically relates to a drilling mechanism for processing control valve flanges. Background Technology

[0002] A flange, also known as a disc, is an important component used for mechanical connections. It is commonly used to connect pipes, valves, pumps, and other equipment, enabling them to connect and ensuring the connection's sealing and stability. Flanges are generally circular discs with a specific thickness and diameter. Their diameter varies depending on the application and connection requirements.

[0003] The primary purpose of drilling holes in flanges is to connect two flanges together using bolts or studs. In piping system or equipment connections, bolts are passed through the corresponding bolt holes on the flanges, and then tightened with nuts to ensure a tight fit between the two flanges. This achieves a reliable connection between pipes and between pipes and equipment. This connection method facilitates installation, disassembly, and maintenance, giving the piping system high flexibility and maintainability.

[0004] In traditional flange drilling operations, once drilling begins, the drill bit rotates at high speed, violently rubbing and cutting against the flange material, instantly generating a large amount of curled or fragmented material chips. These chips are rapidly discharged along the drill bit's spiral grooves. Due to the high drilling speed, the chip generation rate is extremely high, and within just a few minutes, the chip tray will be piled up like a mountain. When the chip accumulation in the tray reaches a certain level and affects the normal progress of drilling, the operator needs to stop the drilling machine. At this time, the chip temperature is high, which can easily burn the operator. This phenomenon has become a problem that urgently needs to be solved by those in this field. Utility Model Content

After the motor 23 starts, it starts to run at high speed, thereby driving the drill bit 25 to rotate synchronously, thus providing continuous power support for subsequent drilling operations.

[0033] An adjustment component 3 is fixedly installed on the base 1. The adjustment component 3 is used to rotate and position the flange, so that the drill bit 25 can drill holes accurately.

[0034] The adjustment assembly 3 includes a second mounting plate 31 fixedly mounted on the base 1. A second motor 32 is fixedly mounted on the second mounting plate 31. A mounting platform 33 is fixedly connected to the output end of the second motor 32. A first movable shaft 39 is fixedly mounted on the mounting platform 33. A circular hole (not shown in the figure) with a diameter adapted to the first movable shaft 39 is opened on the mounting platform 33. The first movable shaft 39 is fixedly connected to the second motor 32. The second motor 32 is suitable for driving the mounting platform 33 and the first movable shaft 39 to rotate.

[0035] A second movable shaft 40 is hinged to the first movable shaft 39. A third fixed plate 55 is fixedly connected to the second movable shaft 40. A flipping component 4 is provided on the third fixed plate 55. The flipping component 4 is used to perform loosening and tightening clamping operations on the flange and can flip and discharge the cut material after cutting, thereby meeting specific processing requirements and improving the convenience and efficiency of the processing process.

[0036] The flipping component 4 includes a fixed plate 41, and a movable shaft 42 is fixedly connected inside the fixed plate 41. The movable shaft 42 passes through both sides of the fixed plate 41.

[0037] One end of the movable shaft 42 is fixedly connected to the gear disk 43. A gear carrier 49 is meshed on one side of the gear disk 43. A small section of the gear carrier 49 has a rack. The gear carrier 49 is fixedly connected to the cylinder 50. The cylinder 50 is fixedly mounted on the mounting plate 51. The mounting plate 51 is fixedly mounted on the bottom of the mounting platform 33. The cylinder 50 is suitable for driving the gear carrier 49 to move upward, so that the gear carrier 49 drives the gear disk 43 to rotate through the meshing of the middle rack, so that the fixed plate 41 drives the movable shaft 40 to rotate to one side.

[0038] The base plate 36 is fixedly installed on the fixed plate 41. The bottom plate 58 is fixed in the middle of the bottom of the base plate 36. The two ends of the base plate 36 are threaded to the lead screw 45. The lead screw 45 is provided with two sets of screw grooves with opposite spiral directions (not shown in the figure). The two ends of the lead screw 45 are threaded to the movable sleeve 46. The movable sleeve 46 is slidably connected to the base plate 58. The base plate 58 extends to the outer ends of the base plate 36.

[0039] The screw 45 has a fixed seat 56 installed on the threaded top bearings on both sides of the screw 45. The fixed seat 56 is fixedly installed at the extension of the base plate 58 to stabilize the rotation of the screw 45.

[0040] One side of the lead screw 45 is fixedly connected to the gear disk 44. The connecting rod 47 is fixedly installed on the movable sleeve 46. The connecting rod 47 is slidably connected to the material cutting disk 37. Two sets of fixing rods 57 are fixedly installed between the material cutting disk 37 and the base 36. The fixing rods 57 are used to firmly fix the base 36 and the material cutting disk 37.

[0041] The connecting rod 47 passes through the cutting disc 37 and is fixedly connected to the clamping block 38. The clamping block 38 is used to clamp the flange. The gear frame 49 meshes with the second gear disc 44, causing the second gear disc 44 to rotate. The rotation of the second gear disc 44 is transmitted to the lead screw 45. When the lead screw 45 rotates, it drives the movable sleeve 46, causing the movable sleeves 46 to move closer to each other. This, in turn, drives the clamping block 38 connected to it to move closer to each other, and finally achieves the clamping operation of the flange.

[0042] The material cutting disc 37 has a protruding post at its center (not shown in the figure). The diameter of the protruding post is matched with the bore diameter of the flange, so that the flange can be quickly and accurately aligned when inserted.

[0043] At least two sets of mounting plates 4 54 are fixedly installed below the mounting platform 33. The mounting plates 4 54 are fixedly installed with cylinder 1 34. The output end of cylinder 1 34 passes through the mounting platform 33. Support rod 2 35 is fixedly connected to cylinder 1 34. One end of support rod 2 35 is provided with block 53. Block 53 is movably sleeved 46 and connected to the square groove 52 opened in the chassis 36. The square groove 52 and block 53 are adapted to each other, so that cylinder 1 34 moves upward and drives support rod 2 35 to move upward, so that block 53 at one end of support rod 2 35 and square groove 52 fit tightly, so that it is stably supported.

[0044] The bottom of the mounting platform 33 has a circular groove 60. Two sets of fixing rods 59 are slidably connected between the mounting platform 33 and the base 1. The fixing rods 59 are used to fix and support the chassis 36 by sliding the mounting platform 33 and the base 1 in the circular groove 60 when the output shaft of the motor 32 rotates.

[0045] Working principle;

[0046] During drilling, cylinder 2 50 is activated, pushing gear frame 49 upward, driving gear disk 2 44 to rotate, which in turn drives lead screw 45 to rotate, causing movable sleeves 46 to approach each other, clamping block 38 clamps flange accordingly. At the same time, gear frame 49 moves upward, driving gear disk 1 43 to rotate, and movable shaft 3 42 drives fixed plate 2 41 to rotate. The movable connection between movable shaft 2 40 and movable shaft 1 39 causes the material cutting disk 37 to flip and reset.

[0047] When cylinder 2 50 drives gear carrier 49 downward, gear disk 2 44 reverses, movable sleeve 46 separates, and clamping block 38 releases flange. At this time, flange needs to be removed to prevent it from falling. When gear carrier 49 moves down to engage with gear disk 1 43, material cutting disc 37 rotates with gear disk 1 43 to realize material cutting and unloading, thereby making production run efficiently and increasing output. As motor 2 32 drives mounting table 33 to rotate, precise drilling can be performed at each position to meet processing requirements.
