Description

Technical Field

[0001] This invention belongs to the field of burner component processing technology, specifically a burner component processing device with a positioning structure. Background Technology

[0002] Flanges are key connecting components of burners, mainly used for sealing the connection between the burner body and the pipes and furnace body. Several mounting bolt holes need to be machined on the flange to ensure assembly coaxiality and connection sealing. Therefore, drilling equipment is required to drill holes on the surface of the flange during processing.

[0003] A patent with publication number CN118417596B discloses a casting drilling device with positioning function, including a platform, a drilling mechanism, a clamping mechanism, a support mechanism and a placement mechanism installed on the platform, wherein the placement mechanism includes a top plate that rotates on the support shell and a casting mechanism is placed on the top plate. The device is equipped with a placement mechanism, which allows for quick alignment of the next nut hole by simply rotating it 90 degrees.

[0004] When the aforementioned casting drilling device with positioning function is in use, after rotating the flange by a specified angle, the drill bit generates a reverse cutting torque when drilling the flange. This torque causes slight wear or elastic torsional deformation between the indexing mechanisms and stores residual torsional stress. When the drill bit finishes drilling and retracts upward, the cutting resistance disappears instantly, and the stored torsional stress is released. The indexing mechanism will then push the positioning plate to rotate slightly. Furthermore, the high-speed rotation of the drilling components during operation will generate vibration throughout the machine. After indexing, the continuous vibration will drive the positioning plate to deviate angularly within the transmission clearance. Over time, this will eventually lead to deviations in the position of the bolt holes during subsequent flange drilling, affecting the quality of the flange and, in severe cases, directly causing the flange workpiece to be scrapped.

[0005] Therefore, the present invention provides a burner component processing apparatus with a positioning structure. Summary of the Invention

[0010] Preferably, the movable plate is internally threaded with a lead screw, which is rotatably connected to the inner wall of the worktable. A toothed column is fixedly connected to the surface of the lead screw. A lifting motor is fixedly connected to the inner upper surface of the worktable.

[0012] Preferably, a limiting block is slidably connected inside the rotating tube, and both ends of the limiting block are provided with slopes. One end of the limiting block is slidably connected to the inclined surface of the wedge block.

[0013] Preferably, a tapered rod is slidably connected inside the sleeve, a first spring is fixedly connected to the lower surface of the tapered rod, a button is fixedly connected to one end of the tapered rod, a control panel is fixedly connected to the outer wall of the workbench, the button and the drilling assembly are electrically connected to the control panel respectively, and a pressing frame is fixedly connected to the lower surface of the liquid separator.

[0014] Preferably, a piston rod is fixedly connected inside the slide groove, the piston rod and the positioning rod are slidably connected inside, a piston component is fixedly connected to one end of the piston rod, the piston component and the inner wall of the positioning rod are sealed to each other, and a second spring is fixedly connected between the positioning rod and the slide groove.

[0015] Preferably, a liquid inlet check valve is fixedly connected to the surface of the positioning rod, and a connecting pipe is fixedly connected to one end of the liquid inlet check valve. A support pipe is fixedly connected to the surface of the dispensing plate, and one end of the connecting pipe is slidably connected inside the support pipe. The surface of the connecting pipe is fixedly connected to the inside of the connecting plate. A fixing pipe is fixedly connected between the lower surface of the dispensing plate and the inside of the storage tank. A cavity is provided on the inner wall of the positioning rod, and a plurality of drain check valves are fixedly connected between the cavity and the inner wall of the positioning rod. A plurality of micropores are provided inside the cavity.

[0016] Preferably, the upper surface of the positioning rod is rotatably connected with a plurality of ball bearings.

[0017] The beneficial effects of this invention are as follows: 1. The burner component processing device with a positioning structure described in this invention, by setting positioning rods, after drilling one hole in the flange, drives the indexing assembly to drive the positioning plate at one end of the rotating rod to rotate synchronously. The positioning plate drives the three-jaw chuck to rotate, and the three-jaw chuck drives the flange to rotate synchronously, so that the drilling position of the flange is changed. After the change is completed, the two positioning rods can be driven to slide upward and move into the positioning holes inside the positioning plate. The two positioning rods enter the positioning holes, and the surface of the positioning rods is in contact with the inner wall of the positioning hole, so that the drilling position of the flange can be positioned. In this device, the positioning rods are in contact with the full circumference of the positioning hole, locking the rotation angle of the positioning plate and avoiding the problem of slight rotation of the flange due to the radial cutting force of the drill bit during drilling. At the same time, it can detect whether the drilling position has deviated.

[0018] 2. The burner component processing device with a positioning structure described in this invention, by setting a positioning rod and a rotating tube, allows one positioning rod to slide into the positioning hole during the upward movement of the positioning rod driven by the fixed frame when a slight deviation occurs in the rotation angle of the positioning plate. This positioning rod cannot enter the positioning hole and slides into the interior of the fixed frame in the groove. Subsequently, the other positioning rod enters the positioning hole. During the upward movement of the positioning rod, the fixed frame is driven to rotate the positioning rod. The positioning rod rotates on the inner wall of the positioning hole. When the positioning rod contacts and fits against the inner wall of the positioning hole, the positioning hole is pushed by the rotation of the positioning rod, causing the positioning hole to drive the positioning plate to rotate. When both positioning rods rotate into the positioning hole, the drilling position of the flange can be determined. This device can automatically complete the correction of the flange drilling position without manual intervention, avoiding the problem that continuous vibration and disturbance after indexing will drive the positioning plate to shift angle within the transmission gap, ultimately causing the bolt hole position to deviate and resulting in the scrapping of the flange workpiece.

[0019] 3. The burner component processing device with a positioning structure described in this invention, by setting a wedge block and a limiting block, when the rotation angle of the positioning plate deviates significantly, both positioning rods slide into the interior of the fixed frame. At this time, the positioning rod drives the connecting rod to descend, the connecting rod drives the wedge block to descend, and the wedge block descends and drives the limiting block to slide synchronously to the outside of the rotating tube. At this time, the first spring drives the cone rod to move upward, the cone rod drives the button to rise, and the button is squeezed after contacting the pressing frame. The button controls the drilling assembly to close through the control panel, and the user can stop the machine for maintenance. This device can trigger a stop lock when the rotation angle of the positioning plate deviates significantly, immediately terminating the drilling process and avoiding the problem of misalignment during flange drilling.

[0020] 4. The burner component processing device with a positioning structure described in this invention, by providing a piston component, when the positioning rod slides downward inside the slide groove, the piston's position inside the positioning rod changes, opening the inlet check valve to allow grease to enter the positioning rod. When the positioning rod returns to its original position and moves upward, the piston component cooperates with the inner cavity of the positioning rod, increasing the pressure inside the cavity, opening the outlet check valve, and discharging the grease into the cavity, then through micropores into the interior of the slide groove. This also lubricates the surface of the positioning rod as it slides, preventing the positioning rod and the slide groove from moving and scraping against each other, thus avoiding the generation of metal abrasive particles during movement. These particles fill the gap between the slide groove and the positioning rod, causing the positioning rod to jam, preventing it from sliding normally within the slide groove, and failing to complete adaptive adjustment correction under small deviations, resulting in misalignment of the hole angle.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figures 1 to 12 As shown in the embodiment of the present invention, a burner component processing device with a positioning structure includes a chassis support 1. A drilling assembly 11 is provided at one end of the chassis support 1. A worktable 2 is fixedly connected to the circumferential surface of the chassis support 1. Several placement racks 21 are threadedly connected to the upper surface of the worktable 2. A positioning disk 22 is rotatably connected to the upper surface of the worktable 2. A three-jaw chuck 23 is fixedly connected inside the positioning disk 22. The specific structure and installation method of the three-jaw chuck 23 are existing technologies and will not be described in detail here. Several positioning holes 223 are opened on the surface of the positioning disk 22. A lifting drive mechanism is provided inside the worktable 2. A rotating tube 44 is installed on the lifting drive mechanism. A liquid distribution plate 45 is fixedly connected to the upper surface of the rotating tube 44. A fixing frame 46 is fixedly connected to the upper surface of the liquid distribution plate 45. A sliding groove 465 is symmetrically opened at the upper end of the fixing frame 46. A positioning rod 47 is slidably connected inside each of the two sliding grooves 465.

[0025] The upper end of the workbench 2 is fixedly connected with multiple vertical plates in a ring array. Each vertical plate has an adjusting bolt threaded on its side. The adjusting bolt passes through the vertical plate, and the end of the adjusting bolt is rotatably connected to the placement frame 21 through a bearing. The upper end of the workbench 2 is provided with multiple moving slots in a ring array. The placement frame 21 is slidably connected to the adjacent moving slots. The placement frame 21 is used to support and limit the flange 3. The number of positioning holes 223 on the positioning plate 22 is the same as the number of holes to be drilled on the flange 3, and they are aligned one by one.

[0026] Specifically, the drilling assembly 11 of this device adopts the prior art, which includes a lowering mechanism for driving the drill bit to descend, a rotating mechanism for driving the drill bit to rotate, and the drill bit. The three-jaw chuck 23 of this device adopts the hydraulic three-jaw chuck 23 in the prior art. The hydraulic system pushes the cylinder piston to move axially, which drives the inclined groove of the internal wedge sleeve to cooperate with the inclined surface of the chuck base jaw, converting the axial thrust into radial clamping force. The rotating rod 222 is hollow, so the rotary cylinder of the hydraulic three-jaw chuck 23 is installed inside the rotating rod 222, and a rotary joint is installed inside the rotary cylinder. When the positioning plate 22 drives the three-jaw chuck 23 to rotate, the rotary cylinder rotates synchronously with the rotating rod 222. High-pressure oil is continuously sent into the rotating cylinder through the rotary joint, and there will be no problems of pipeline entanglement or oil interruption due to rotation.

[0027] When drilling a flange 3 used to connect burner tubes, the flange 3 is generally positioned above the workbench 2 and clamped and fixed by a three-jaw chuck 23. Then, the drilling assembly 11 is driven down and the drill bit drills the flange 3. After the flange 3 completes one drilling operation, the indexing mechanism drives the flange 3 to rotate to a specified angle and drills again. Repeating the above operation can complete the drilling operation of the flange 3. In existing drilling equipment, after the indexing mechanism drives the flange 3 to rotate by a specified angle, the drill bit generates a reverse cutting torque when drilling the flange 3. The torque causes slight elastic torsional deformation between the indexing mechanisms and stores residual torsional stress. When the drill bit completes drilling and retracts upward, the cutting resistance disappears instantly, and the stored torsional stress is released. The indexing mechanism will push the positioning plate 22 to rotate slightly. During the operation of the equipment, the high-speed rotation of the drilling assembly 11 will generate vibration of the whole machine. After the indexing is completed, the vibration disturbance caused by continuous or long-term operation will cause the accuracy of the intermittent transmission of the indexing mechanism to deviate. This will cause the positioning plate 22 and the flange 3 to shift at an angle during the rotation adjustment process, resulting in a deviation in the position of the hole to be drilled on the flange 3. Ultimately, this will cause a deviation in the position of the bolt hole, resulting in the scrapping of the flange 3. During this process, the positioning hole 223 of the positioning plate 22 and the position of the hole to be drilled on the flange 3 are always aligned. When a deviation occurs, the positioning hole 223 of the positioning plate 22 and the position of the hole to be drilled on the flange 3 will deviate simultaneously.

[0028] To solve the above technical problems, when using the device, the flange 3 is placed above the placement rack 21, and then the jaws on the three-jaw chuck 23 are driven to move. The jaws position and clamp the inner wall of the flange 3. After clamping, the drilling assembly 11 is driven to descend and the drilling assembly 11 performs drilling operation on the flange 3. Before the drilling assembly 11 descends, the lifting drive mechanism drives the fixing frame 46 to move upward. The fixing frame 46 drives the positioning rod 47 to move upward, so that the two positioning rods 47 simultaneously enter the positioning hole 223 inside the positioning disk 22, and the surface of the positioning rod 47 fits against the inner wall of the positioning hole 223. This locks the position of the positioning disk 22 during drilling. After drilling a hole, when the drilling assembly 11 rises, the lifting drive mechanism drives the fixing frame 46 and the positioning rod 47 to descend and reset. Subsequently, the indexing assembly 24 drives the positioning disk 22 to rotate, and the positioning disk 22 drives the three-jaw chuck 23 and the flange 3 to rotate at a specified angle, and drills the holes to be processed later. After the positioning disk 22 has rotated, the fixing frame 46 and positioning rod 47 move upwards. When the positioning disk 22 deviates slightly from its rotation position, the fixing frame 46 drives the two positioning rods 47 to move into the positioning hole 223. One positioning rod 47 will enter the positioning hole 223, while the other positioning rod 47 will be limited by the lower part of the positioning disk 22 and cannot enter the positioning hole 223. As the two positioning rods 47 move upwards, the blocked positioning rod 47 is squeezed by the lower part of the positioning disk 22, causing the positioning rod 47 to slide into the groove 465 inside the fixing frame 46. Then, the rotating tube 44 is driven to rotate, and the rotating tube 44 drives the dispensing disk 45 and the fixing frame 46 to rotate synchronously. The frame 46 drives the two positioning rods 47 to rotate synchronously. The two positioning rods 47 rotate, with one positioning rod 47 rotating on the inner wall of the positioning hole 223 and the other positioning rod 47 rotating on the lower surface of the positioning plate 22. When the positioning rod 47 rotates and comes into contact with the inner wall of the positioning hole 223, as the positioning rod 47 continues to rotate, it will push the positioning hole 223 to move synchronously. The positioning hole 223 drives the positioning plate 22 to rotate synchronously until the positioning hole 223 is directly above the two positioning rods 47. At this time, both positioning rods 47 have entered the positioning hole 223, and the position of the positioning plate 22 can be corrected. After the correction is completed, the drilling assembly 11 can be driven to descend to complete the drilling operation on the flange 3.

[0029] The positioning rod 47 of this device fits in full circumference with the positioning hole 223, which limits the positioning plate 22. It can also automatically correct the drilling position of the flange 3 after the positioning plate 22 shifts, without manual intervention. This avoids the problem of the flange 3 rotating slightly due to the radial cutting force of the drill bit during drilling, and the problem of the positioning plate 22 shifting at an angle within the transmission clearance, which would cause the indexing angle of the flange 3 hole to be misaligned, thus resulting in a decrease in workpiece quality.

[0030] like Figure 3 As shown, a rotating rod 222 is fixedly connected to the lower surface of the positioning disk 22 and extends into the interior of the worktable 2. The rotating rod 222 is rotatably connected to the worktable 2 via a bearing. An indexing component 24 is provided on the surface of the rotating rod 222. A dust cover 221 is fixedly connected to the upper surface of each positioning hole 223. The dust cover 221 is tapered to prevent the debris and cutting fluid generated during drilling from entering the interior of the positioning hole 223. The debris falls onto the surface of the dust cover 221 and can be automatically washed off by the cutting fluid.

[0031] Specifically, the indexing component 24 used in this device is existing technology. It includes an actuating component and a driven component. The driven component is installed on the surface of the rotating rod 222, and the actuating component is fixedly connected to the output shaft of the rotary motor. The rotary motor is installed inside the worktable 2. Its working principle is as follows: the rotary motor drives the actuating component to rotate, and the actuating component rotates and enters the groove on the surface of the driven component, pushing the driven component to rotate intermittently, thus completing the indexing operation. The indexing component 24 can be replaced by a gap divider, which can realize intermittent rotation and drive the jaws and flange 3 to rotate intermittently to complete the drilling operation.

[0032] like Figure 5 As shown, the lifting drive mechanism includes a fixed rod 4 fixedly connected inside the worktable 2. A movable plate 41 is slidably connected to the surface of the fixed rod 4. A liquid storage tank 42 is fixedly connected to the upper surface of the movable plate 41. A sleeve 43 is fixedly connected to the upper surface of the liquid storage tank 42. The upper surface of the sleeve 43 is rotatably connected to one end of a rotating tube 44. A driven gear 442 is fixedly connected to the surface of the rotating tube 44. A lead screw 411 is threadedly connected inside the movable plate 41. The lead screw 411 is rotatably connected between the inner wall of the worktable 2. A gear column 412 is fixedly connected to the surface of the lead screw 411. A lifting motor 48 is fixedly connected to the inner upper surface of the worktable 2. A drive gear 481 is fixedly connected to the output end of the lifting motor 48. Both the drive gear 481 and the driven gear 442 mesh with the gear column 412. Under normal working conditions, the gear column 412 and the driven gear 442 always remain in a meshed state.

[0033] Specifically, when it is necessary to drive the positioning rod 47 to rise and rotate, the lifting motor 48 can be turned on. The lifting motor 48 drives the drive gear 481 to rotate. The drive gear 481 meshes with the gear column 412, causing the drive gear 481 to drive the lead screw 411 to rotate. The lead screw 411 is threadedly connected to the moving plate 41. The lead screw 411 pushes the moving plate 41 to move up and down, causing the moving plate 41 to slide on the surface of the fixed rod 4. The moving plate 41 drives the liquid storage tank 42, sleeve 43, rotating tube 44, dispensing plate 45, and fixed frame 46 to rise synchronously. The fixed frame 46 drives the positioning rod 47 inside to rise synchronously. When the rotating tube 44 rises, it drives the driven gear 442 to rise synchronously. The driven gear 442 meshes with the gear column 412, causing the driven gear 442 to drive the rotating tube 44 to rotate. The rotating tube 44 can then drive the fixed frame 46 to rotate synchronously. The fixed frame 46 drives the positioning rod 47 inside to rotate synchronously.

[0034] The fixed frame 46 drives the positioning rods 47 to move upward and rotate simultaneously. When the positioning hole 223 is aligned with the two positioning rods 47, the two positioning rods 47 will directly insert into the positioning hole 223 to lock the positioning plate 22. When the positioning plate 22 has a small deviation, one positioning rod 47 is aligned with the positioning hole 223, while the other positioning rod 47 is misaligned. At this time, one positioning rod 47 will be inserted into the positioning hole 223, while the other positioning rod 47 will be in contact with the bottom of the positioning plate 22. The positioning rod 47 inserted into the positioning hole 223 continues to rotate and pushes the positioning plate 22 to adjust its position, so that the positioning plate 22 returns to the correct position. The positioning plate 22 drives the three-jaw chuck 23 and the flange 3 to rotate synchronously, thereby completing the adjustment and correction of the position of the flange 3 and ensuring the accuracy of drilling. If both positioning rods 47 are misaligned with the positioning holes 223, when the fixing frame 46 rises, the upper ends of both positioning rods 47 will abut against the bottom of the positioning plate 22. During the rising process of the fixing frame 46, the fixing frame 46 is sleeved on the outside of the two positioning rods 47.

[0035] like Figure 7 As shown, a slide rail is fixedly connected to the surface of the fixed frame 46, a connecting plate 461 is slidably connected to the surface of the slide rail, a connecting rod 463 is fixedly connected inside the connecting plate 461, and a wedge block 464 is fixedly connected to one end of the connecting rod 463.

[0036] like Figures 7 to 10 As shown, a limiting block 441 is slidably connected inside the rotating tube 44. Both ends of the limiting block 441 are provided with slopes. One end of the limiting block 441 is slidably connected to the inclined surface of the wedge block 464. A T-shaped guide rail protrudes from the inclined surface of the wedge block 464. A T-shaped groove adapted to the T-shaped guide rail is opened on the slope surface where the limiting block 441 contacts the wedge block 464. The T-shaped guide rail is slidably connected to the T-shaped groove. One end of the limiting block 441 is slidably connected to the inclined surface of the wedge block 464 through the T-shaped groove. A tapered rod 431 is slidably connected inside the sleeve 43. The upper end of the tapered rod 431 is tapered. The shape of the limiting block 441 is set as an isosceles trapezoid.

[0037] like Figure 10As shown, a first spring 432 is fixedly connected to the lower surface of the cone rod 431. After the cone rod 431 is driven to rise to the highest position by the first spring 432, the slope of the limiting block 441 and the inclined surface of the cone rod 431 remain in close contact. A button 433 is fixedly connected to one end of the cone rod 431. A control panel 25 is fixedly connected to the outer wall of the workbench 2. The button 433 and the drilling assembly 11 are electrically connected to the control panel 25 respectively. A pressing frame 452 is fixedly connected to the lower surface of the liquid distribution plate 45. The pressing frame 452 is located directly above the button 433. The button 433 and the control panel 25 of this device are both existing technologies. The button 433 is a button 433 switch with a self-resetting function. When the button 433 is pressed, it outputs a signal to the control system of the control panel 25, and the control system issues a stop command to the drilling assembly 11.

[0038] Specifically, when the angle of the positioning disk 22 deviates significantly, and both positioning rods 47 are misaligned with the positioning holes 223, making it difficult to correct the positioning rods 47, the fixing frame 46 drives the positioning rods 47 to move upward. The two positioning rods 47 rotate and are squeezed on the lower surface of the positioning disk 22. At this time, the fixing frame 46 continues to move upward, causing the fixing frame 46 to drive the sliding groove 465 to slide on the surface of the positioning rods 47. The fixing frame 46 drives the dispensing disk 45, rotating tube 44, and sleeve 43 to move upward synchronously. The dispensing disk 45 drives the support tube 453 to move upward. The upward sliding causes the support tube 453 to slide upward on the surface of the connecting tube 462. The rotating tube 44 drives the limiting block 441 to slide upward synchronously. The limiting block 441 slides on the T-shaped guide rail on the surface of the wedge block 464 through the T-slot, causing the limiting block 441 to slide inward away from the rotating tube 44. Initially, one end of the limiting block 441 is in contact with the upper surface of the cone rod 431. At this time, the cone rod 431 compresses the first spring 432. Under the action of the elastic force of the first spring 432, the cone rod 431 maintains the upward movement trend. When the two limiting blocks 441 slide on the inclined surface of the wedge block 464, the slope of the two limiting blocks 441 away from the wedge block 464 contacts the inclined surface of the cone rod 431. The limiting blocks 441 release their restriction on the cone rod 431, causing the first spring 432 to drive the cone rod 431 to move upward. When the two positioning rods 47 are fully inserted into the slide groove 465, the cone rod 431 drives the button 433 to move upward, causing the button 433 to contact and press the pressing frame 452. The button 433 is pressed and transmits an electrical signal through the control panel 25. The control system of the control panel 25 issues a stop command, which controls the drilling assembly 11 to stop working. Then, the staff performs maintenance and replaces the transmission assembly for convenient subsequent use.

[0039] This device can trigger a stop lock when the rotation angle of the positioning plate 22 deviates significantly, immediately terminating the drilling process and preventing misalignment of the flange 3 during drilling.

[0040] Example 2, as Figures 6 to 12 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a piston rod 466 is fixedly connected inside the slide groove 465, a piston cavity is opened inside the positioning rod 47, the piston rod 466 and the positioning rod 47 are slidably connected inside, one end of the piston rod 466 extends into the piston cavity and is fixedly connected to a piston component 467, the piston component 467 is slidably connected to the piston cavity, the inner wall of the piston component 467 and the positioning rod 47 are sealed, and a second spring 468 is fixedly connected between the positioning rod 47 and the slide groove 465.

[0041] like Figure 11 As shown, a liquid inlet check valve 471 is fixedly connected to the surface of the positioning rod 47, and a connecting pipe 462 is fixedly connected to one end of the liquid inlet check valve 471. A support pipe 453 is fixedly connected to the surface of the distributing plate 45, and one end of the connecting pipe 462 is slidably connected inside the support pipe 453. The surface of the connecting pipe 462 is fixedly connected to the inside of the connecting plate 461. A fixing pipe 451 is fixedly connected between the lower surface of the distributing plate 45 and the inside of the storage tank 42. An annular cavity 472 is provided on the inner wall of the positioning rod 47. Several drain check valves 473 are fixedly connected between the cavity 472 and the bottom of the inner wall of the positioning rod 47. Several micropores 474 are provided on the side wall of the cavity 472.

[0042] A movable groove is provided through the side of the slide 465. The connecting pipe 462 passes through the movable groove. When the positioning rod 47 retracts to the slide 465 or slides along the slide 465, the connecting pipe 462 slides along the movable groove without causing obstruction. The fixed tube 451 passes through the inside of the tapered rod 431, and the tapered rod 431 and the fixed tube 451 are slidably connected; The inlet of the liquid inlet check valve 471 is fixed and connected to one end of the connecting pipe 462. The outlet of the liquid inlet check valve 471 is fixed and connected to the inner wall of the positioning rod 47. The inlet of the liquid outlet check valve 473 is fixed and connected to the inner lower surface of the positioning rod 47. The outlet of the liquid outlet check valve 473 is connected to the inside of the cavity 472. The micropore 474 is connected to the outside, so that the lubricating oil stored in the cavity 472 can flow out along the micropore 474. Specifically, when the positioning rod 47 retracts into the groove 465 and extends upward to reset and slide, the positioning rod 47 moves on the inner wall of the groove 465 and scrapes against each other, resulting in dry friction. During the movement, dry friction generates metal abrasive particles. These metal abrasive particles increase with the number of movements and fill the gap between the groove 465 and the positioning rod 47, causing the positioning rod 47 to jam. This prevents the positioning rod 47 from sliding normally within the groove 465, thus failing to complete adaptive adjustment correction even when the deviation of the positioning plate 22 is small, leading to the problem of misalignment of the hole angle. To avoid dry friction, existing technologies mostly rely on manual periodic application of grease to the friction pair. If the amount of grease applied is insufficient, the grease will be quickly consumed, failing to continuously isolate the metal mating surfaces, further aggravating friction and wear, and continuously generating metal abrasive particles, so the positioning rod 47 still has the risk of jamming.

[0043] To solve the above-mentioned technical problems, this device uses the following method: When the positioning rod 47 is compressed and slides downward in the slide groove 465, the piston 467 slides in the inner wall of the positioning rod 47, and the positioning rod 47 slides on the surface of the piston rod 466 and compresses the second spring 468, thereby increasing the distance between the piston 467 and the lower surface of the piston chamber, which generates a negative pressure effect, causing the liquid inlet check valve 471 to open, and the grease in the storage tank 42 is pumped to the fixed position through the connecting pipe 462, support pipe 453, distribution plate 45 and fixed pipe 451. Inside the positioning rod 47, when the pressure of the positioning disc 22 on the positioning rod 47 is released, the second spring 468 drives the positioning rod 47 to move upward, and the distance between the inner lower surface of the positioning rod 47 and the piston 467 decreases. At this time, the piston 467 can discharge the grease into the cavity 472 through the drain check valve 473, and finally discharge it into the inner wall of the slide groove 465 and the movable groove through the micropore 474 of the cavity 472. This ensures that there is grease between the positioning rod 47 and the slide groove 465, and between the connecting pipe 462 and the movable groove, thereby reducing the friction during movement.

[0044] This device utilizes the reciprocating sliding of the positioning rod 47 to achieve automatic grease injection, eliminating the need for manual grease replenishment during machine shutdown. It can supply a quantitative amount of grease with each sliding motion, continuously lubricating the friction pair formed by the positioning rod 47 and the slide groove 465. This reduces the metal scraping effect caused by dry friction, reduces the generation of metal abrasive particles, and prevents the positioning rod 47 from jamming due to abrasive particle accumulation. It ensures smooth sliding and avoidance of the positioning rod 47, guarantees the normal operation of the adaptive toggle correction function of the positioning plate 22, and prevents the flange hole angle misalignment problem.

[0045] like Figure 12 As shown, a plurality of ball bearings 475 are rotatably connected to the upper surface of the positioning rod 47.

[0046] Specifically, when the positioning disk 22 shifts position, the positioning rod 47 is squeezed, and the ball 475 contacts the lower surface of the positioning disk 22. The ball 475 rotates synchronously with the positioning rod 47. The ball 475 rotates on the surface of the positioning rod 47, which reduces the friction between the positioning rod 47 and the positioning disk 22.

[0047] Working principle: When using this device, the flange 3 is placed above the placement rack 21, and then the jaws on the three-jaw chuck 23 are driven to move. The jaws position and clamp the inner wall of the flange 3. After clamping, the drilling assembly 11 is driven to descend and the drilling assembly 11 performs drilling operation on the flange 3. Before the drilling assembly 11 descends, the lifting motor 48 can be turned on. The lifting motor 48 drives the drive gear 481 to rotate. The drive gear 481 meshes with the gear column 412, causing the gear to drive the lead screw 411 to rotate. The lead screw 411 is threadedly connected to the moving plate 41. The lead screw 411 pushes the moving plate 41 to move up and down. The moving plate 41 drives the liquid storage tank 42, sleeve 43, rotating tube 44, liquid distribution plate 45, and fixed frame 46 to rise synchronously. The fixed frame 46 drives its internal positioning rod 47 to rise synchronously. The fixed frame 46 drives the positioning rod 47 to move upward. The positioning rod 47 enters the positioning hole 223 inside the positioning plate 22, and the surface of the positioning rod 47 is in contact with the inner wall of the positioning hole 223, so that the position of the positioning plate 22 can be locked during drilling. When the drilling assembly 11 rises, the drive fixing frame 46 drives the positioning rod 47 to descend and reset. Then, the indexing assembly 24 drives the positioning plate 22 to rotate. The positioning plate 22 drives the three-jaw chuck 23 and the flange 3 to rotate at a specified angle and drill the subsequent holes. After the positioning disk 22 has rotated, the fixing frame 46 and the positioning rod 47 move upward. When the positioning disk 22 rotates slightly, the fixing frame 46 drives the two positioning rods 47 to move into the positioning hole 223. One positioning rod 47 will enter the positioning hole 223, while the other positioning rod 47 will be limited by the lower part of the positioning disk 22, preventing it from entering the positioning hole 223. As the two positioning rods 47 move upward, the blocked positioning rod 47 is squeezed by the lower part of the positioning disk 22, causing the fixing frame 46 to continue to move upward. The fixing frame 46 drives the slide groove 465 to slide on the surface of the positioning rod 47. During this process, as the rotating tube 44 rises, it drives the driven gear 442 to rise synchronously. The driven gear 442 meshes with the gear 412, causing the driven gear 442 to drive the rotating tube 44 to rotate. The rotating tube 44 then drives the fixed frame 46 to rotate synchronously. The fixed frame 46 drives the positioning rod 47 inside it to rotate synchronously. The rotating tube 44 drives the dispensing plate 45 and the fixed frame 46 to rotate synchronously. The two positioning rods 47 rotate, one of which rotates on the inner wall of the positioning hole 223, and the other rotates on the lower surface of the positioning plate 22. When the fixed plate 44 rotates, the positioning rod 47 rotates on the lower surface of the positioning plate 22. After the positioning rod 47 rotates and fits against the inner wall of the positioning hole 223, as the positioning rod 47 continues to rotate, it will push the positioning hole 223 to move synchronously. The positioning hole 223 will drive the positioning disk 22 to rotate synchronously. When both positioning rods 47 are aligned with the positioning hole 223, under the elastic force of the second spring 468, one of the positioning rods 47 that is not inserted into the positioning hole 223 will also enter the positioning hole 223. The position of the positioning disk 22 can then be corrected. After the correction is completed, the drilling assembly 11 can be driven to descend to complete the drilling operation on the flange 3. When the angle of the positioning disk 22 deviates significantly, and both positioning rods 47 are misaligned with the positioning holes 223, and the positioning rods 47 are difficult to correct, the fixing frame 46 drives the positioning rods 47 to move upward. The two positioning rods 47 rotate on the lower surface of the positioning disk 22 and are squeezed. At this time, the fixing frame 46 continues to move upward, causing the fixing frame 46 to drive the sliding groove 465 to slide on the surface of the positioning rods 47. The fixing frame 46 drives the dispensing disk 45, the rotating tube 44, and the sleeve 43 to move upward synchronously. The dispensing disk 45 drives the support tube 453 to slide upward, causing the support tube 453 to slide upward on the surface of the connecting tube 462. The rotating tube 45... 4. The limiting block 441 slides upward synchronously. At this time, the positioning rod 47, connecting plate 461, connecting rod 463 and wedge block 464 are in a relatively fixed state. The limiting block 441 slides on the T-shaped guide rail on the surface of the wedge block 464 through the T-slot. The position of the wedge block 464 is fixed, so that when the limiting block 441 slides upward, it also slides away from the interior of the rotating tube 44. Initially, one end of the limiting block 441 is in contact with the upper surface of the cone rod 431. At this time, the cone rod 431 compresses the first spring 432. Under the action of the elastic force of the first spring 432, the cone rod 431 maintains the upward movement trend. When the two limiting blocks 441 slide on the inclined surface of the wedge block 464, the slope of the two limiting blocks 441 away from the wedge block 464 contacts the inclined surface of the cone rod 431. The limiting blocks 441 release their restriction on the cone rod 431, so that the first spring 432 drives the cone rod 431 to move upward. When the two positioning rods 47 are fully inserted into the slide groove 465, the cone rod 431 drives the button 433 to move upward, so that the button 433 contacts and presses the pressing frame 452. The button 433 is pressed and transmits an electrical signal through the control panel 25. The control system of the control panel 25 issues a stop command, which controls the drilling assembly 11 to stop working. Then, the staff performs maintenance and replaces the transmission assembly to facilitate subsequent use. When the positioning rod 47 is pressed and slides downward in the slide groove 465, the piston 467 slides in the inner wall of the positioning rod 47, and the positioning rod 47 slides on the surface of the piston rod 466 and presses the second spring 468, which increases the distance between the piston 467 and the lower surface of the piston chamber, thus generating a negative pressure effect. This causes the liquid inlet check valve 471 to open, and the grease in the storage tank 42 is pumped into the interior of the positioning rod 47 through the connecting pipe 462, support pipe 453, liquid distribution plate 45, and fixed pipe 451. When the pressure of the positioning plate 22 on the positioning rod 47 is released, the second spring 468 drives the positioning rod 47 to move upward, and the distance between the inner lower surface of the positioning rod 47 and the piston 467 decreases. At this time, the piston 467 can discharge the grease into the cavity 472 through the drain check valve 473, and finally discharge it into the inner wall of the slide groove 465 and the movable groove through the micropore 474 of the cavity 472. This ensures that there is grease between the positioning rod 47 and the slide groove 465, and between the connecting pipe 462 and the movable groove, thereby reducing the friction during movement.
