Description

[0001] The invention relates to the technical field of bearing seat drilling machines, in particular to a drilling machine based on fine grinding of the inner hole of a deep hole bearing seat. Background Art

[0002] The bearing seat drilling machine is a special machine tool equipment specially used for drilling bearing seat parts. Its main structure usually includes a bed, a spindle box, a feed system, a positioning fixture and a control system. It can be designed according to the specifications, materials and drilling process requirements of the bearing seat. Its main function is to accurately process a hole system on the bearing seat that meets the requirements of dimensional accuracy, position accuracy and surface roughness. These holes are used to install bearings, connecting bolts or other components to ensure that the bearing seat can accurately support the rotating shaft in the mechanical equipment and ensure the stability and reliability of the transmission system.

[0003] In a Chinese patent with publication number CN207642345U, an automatic drilling device for a horizontal lathe is disclosed. When the automatic drilling device of a horizontal lathe is used, the drill bit makes little noise when drilling a workpiece and will not affect the surrounding environment. In addition, waste materials on the workpiece will not splash on the workers during drilling. The high degree of automation of the automatic drilling device greatly reduces labor, reduces processing costs, and saves energy. The drilling device drill bit can drill the workpiece 24 hours a day through a screw rod, and the drill bit has high working efficiency and good drilling coordination effect during the drilling process, so that the quality and smoothness of the processed workpiece are guaranteed.

DETAILED DESCRIPTION

[0034] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0035] In order to solve the technical problem of how to improve drilling efficiency, Figure 1 and Figures 8-12As shown, the following preferred technical solutions are provided: a drilling machine tool based on fine grinding of the inner hole of a deep hole bearing seat, comprising a drilling machine pillar 1, a top cover 2 is fixedly mounted on the upper surface of the drilling machine pillar 1, a drill bit 6 and a grinding assembly 4 for grinding are arranged inside the top cover 2, a receiving groove 11 is opened on the inner wall of the drilling machine pillar 1, a T-shaped groove 12 is opened on the inner wall of the receiving groove 11, a cleaning component 5 for cleaning the drill bit 6 is arranged inside the receiving groove 11, a bottom plate 3 is fixedly mounted on the lower surface of the drilling machine pillar 1, a bearing seat 37 is arranged inside the bottom plate 3, and the drill bit 6 and the bearing seat 37 are on the same vertical line;

[0036] The cleaning component 5 includes a rectangular frame 52 movably arranged inside the T-shaped slot 12, T-shaped plates 524 are fixedly installed on both sides of the rectangular frame 52, and the T-shaped plates 524 are slidably connected to the T-shaped slot 12. An electric telescopic rod B51 is fixedly installed on one side of the drilling machine pillar 1, and an air blowing component 53 for further cleaning the drill bit 6 is fixedly installed on one end of the electric telescopic rod B51. A wiping component 54 for wiping the drill bit 6 is movably arranged inside the air blowing component 53. The air blowing component 53 is located inside the rectangular frame 52, and the cleaning component 5 and the drill bit 6 are on the same horizontal line. The drill bit 6 and the grinding assembly 4 can respectively perform drilling and grinding operations on the bearing seat 37, and then the drill bit 6 can be cleaned by the wiping assembly 54 to remove debris attached to the surface of the drill bit 6, and the air blowing assembly 53 will clean the water stains remaining on the surface of the drill bit 6. The cleaning of the drill bit 6 by the wiping assembly 54 and the air blowing assembly 53 can improve the quality of the continuous operation of the drill bit 6. The drill bit 6 and the grinding assembly 4 can switch work, thereby improving the production efficiency of the bearing seat 37, thereby improving the working efficiency of the drilling machine.

[0037] The wiping assembly 54 includes a movable plate 541 movably arranged on the inner wall of the air blowing assembly 53, a sponge 549 is fixedly installed on the upper surface of the movable plate 541, and sliding rods 542 are fixedly installed on both sides of the movable plate 541. A reciprocating groove 523 is opened on one side of the rectangular frame 52, and the reciprocating groove 523 is slidably connected to the movable plate 541. Through the connection relationship between the reciprocating groove 523 and the movable plate 541, when the wiping assembly 54 starts to move inside the rectangular frame 52, the sponge 549 will reciprocate and rise and fall through the movable plate 541 and the reciprocating groove 523, and when the wiping assembly 54 starts to move inside the rectangular frame 52, the sponge 549 will reciprocate and rise and fall through the movable plate 541 and the reciprocating groove 523. When the sponge 549 moves, it is about to contact the drill bit 6. When the sponge 549 starts to move back and forth, it will clean the drill bit 6, initially absorb the excess coolant, and at the same time clean the debris stuck in the threaded hole of the drill bit 6, so that the drill bit 6 can improve its efficiency when working continuously. In contrast, when the existing bearing seat 37 is drilling, excess coolant is likely to remain on the surface of the drill bit 6, and debris is likely to be stuck in the threaded hole of the drill bit 6. These situations will cause the coolant to be unable to be cleaned in time, and the accumulation of debris will affect the working state of the drill bit 6, thereby reducing the efficiency of the drill bit 6 during continuous drilling operations.

[0038] A vertical groove 543 is provided on the surface of the movable plate 541, and a bottom groove 546 is provided on the surface of the movable plate 541. A threaded rod B544 is movably installed on the inner wall of the bottom groove 546. A gear B545 is fixedly installed on one end of the threaded rod B544. The gear B545 is located inside the vertical groove 543. A slider 548 is provided on the outer surface of the bottom groove 546. An extrusion plate 547 is fixedly installed on the upper surface of the slider 548. There are two groups of extrusion plates 547. The two groups of extrusion plates 547 are located on one side of the sponge 549. A slider 548 is also fixedly installed on one side of the movable plate 541. The slider 548 is located inside the air blowing component 53. Through one group of sliders 548, the movable plate 541 can be stably reciprocated and lifted inside the air blowing component 53. When the movable plate 541 drops, the wiping component 54 will cooperate with the air blowing component 53 to allow the threaded rod B544 to open. When the sponge 549 is wrapped around the drill bit 6, the squeezing of the squeezing plate 547 can make the sponge 549 further fully contact with the drill bit 6, so that the sponge 549 can further fit the inside of the threaded groove on the surface of the drill bit 6, thereby further improving the cleaning effect. When the liquid inside the sponge 549 is gradually saturated, the squeezing of the squeezing plate 547 can also squeeze out the saturated water inside the sponge 549, so that the sponge 549 can continue to maintain its water absorption. In contrast, when the existing bearing seat 37 is drilling, it is difficult for the sponge 549 to fully fit the inside of the threaded groove on the surface of the drill bit 6, and the cleaning effect is poor. When the liquid inside the sponge 549 is saturated, the water cannot be squeezed out in time, resulting in insufficient water absorption of the sponge 549, affecting the cleaning effect of the drill bit 6.

[0039] The air blowing assembly 53 includes a slide plate 531 fixedly mounted on one end of the electric telescopic rod B51, on one side of which a magnet B532 is fixedly mounted, a magnet A522 is fixedly mounted on the inner wall of the rectangular frame 52, the magnet A522 and the magnet B532 are magnetically attracted to each other, an inner groove 533 is provided on the inner wall of the slide plate 531, a guide rod is fixedly mounted on the bottom of the inner groove 533, the guide rod is movably connected to a slider 548 on one side of the movable plate 541, the slider 548 is adapted to the inner groove 533, a rod hole 521 is provided on one side of the rectangular frame 52, the rod hole 521 is adapted to the electric telescopic rod B51, when the electric telescopic rod B51 is started, the rectangular frame 52 will gradually move out from the inside of the T-slot 12, and when the T-slot When the plate 524 contacts one side of the T-slot 12, the rectangular frame 52 will move to the extreme position. At this time, the electric telescopic rod B51 that continues to extend will allow the air blowing component 53 to separate from the rectangular frame 52. At the same time, the sponge 549 is about to contact the drill bit 6. When the air blowing component 53 begins to move from the inside of the rectangular frame 52, the sliding rod 542 on one side of the movable plate 541 will move back and forth along the reciprocating groove 523, allowing the sponge 549 to wipe the drill bit 6 back and forth. In contrast, the existing bearing seat 37 cannot allow the cleaning component to accurately move to the drill bit 6 position and realize reciprocating wiping when drilling, resulting in the coolant and debris on the surface of the drill bit 6 being difficult to effectively clean, and the cleaning effect is poor.

[0040] The drilling machine tool cut by the slide 531, the surface of the air blowing component 53 is fixedly installed with a tooth plate 534, the tooth plate 534 is located inside the vertical slot 543, the tooth plate 534 is meshed with the gear B545, the bottom of the slide 531 is fixedly installed with an air bag 535, the upper surface of the air bag 535 is fixedly installed with the lower surface of the movable plate 541, the outer surface of the air bag 535 is fixedly installed with an L tube 536, one end of the L tube 536 is fixedly installed with a shunt pipe 537, both ends of the shunt pipe 537 are fixedly installed with an L plate 538, one end of the L plate 538 is fixedly installed with the upper surface of the movable plate 541, one end of the L plate 538 is provided with an air jet 5381, an electric heating wire is provided inside the air jet 5381, a distribution box 539 is fixedly installed on one side of the L plate 538, the electric heating wire is linearly connected to the distribution box 539, and the movable plate 541 is lowered to The air bag 535 can be squeezed to allow the gas inside the air bag 535 to enter the L tube 536 and the shunt tube 537. Then the gas will pass through the L plate 538 to the air jet pipe 5381, and then be ejected through the electric heating wire. At this time, the hot air ejected will contact the surface of the drill bit 6 to preliminarily dry the moisture before the drill bit 6 is cleaned. When the movable plate 541 begins to reset, the hot air ejected from the air jet pipe 5381 will also dry the residual moisture on the surface of the drill bit 6, and can also blow away fine impurities and preheat the surface of the drill bit 6, thereby improving the corrosion resistance of the drill bit 6. In contrast, the existing bearing seat 37 cannot effectively dry the moisture on the surface of the drill bit 6 after cleaning when drilling. The residual moisture can easily cause the drill bit 6 to rust, and it is difficult to blow away fine impurities and preheat the surface of the drill bit 6, affecting the corrosion resistance and working performance of the drill bit 6.

[0041] Specifically, when the drill bit 6 completes the drilling work, the electric telescopic rod B51 starts and drives the rectangular frame 52 to move out from the inside of the T-slot 12. At this time, the T-plate 524 slides along the T-slot 12 until it contacts the side of the slot to move the rectangular frame 52 to the limit position. Then the electric telescopic rod B51 continues to extend to allow the air blowing assembly 53 to separate from the rectangular frame 52. At this time, the magnetic adsorption effect of the magnet A522 and the magnet B532 is released. When the air blowing assembly 53 moves, the sliding rod 542 on one side of the movable plate 541 moves back and forth along the reciprocating groove 523 on the rectangular frame 52, driving the sponge 549 to wipe the surface of the drill bit 6 back and forth to absorb excess coolant and clean the debris in the threaded hole. At the same time, when the movable plate 541 descends, the tooth plate 534 on the surface of the air blowing assembly 53 engages with the gear B545 , driving the threaded rod B544 to rotate, so that the two sets of squeezing plates 547 approach each other and squeeze the sponge 549, allowing the sponge 549 to fit more fully into the inside of the thread groove of the drill bit 6, thereby improving the cleaning effect. When the sponge 549 is saturated with water, the squeezing of the squeezing plate 547 can also squeeze out the water to maintain the water absorption of the sponge 549. During the descending process of the movable plate 541, its lower surface squeezes the airbag 535, so that the gas in the airbag 535 enters the jet pipe 5381 through the L tube 536 and the diverter pipe 537, and is heated by the internal electric heating wire and then ejected hot air to preliminarily dry the moisture on the surface of the drill bit 6. When the movable plate 541 is reset, the jet pipe 5381 continues to eject hot air to dry the residual moisture and blow away fine impurities, while preheating the surface of the drill bit 6 to enhance its corrosion resistance, thereby improving the overall drilling efficiency.

This adjustment can change the orientation of the bearing seat 37 placed on the carrier plate 36, so that the drill bit 6 can be accurately aligned with each drilling point of the bearing seat 37, realizing all-round drilling operations on the bearing seat 37, effectively expanding the processing range of the drilling machine tool, improving the flexibility and applicability of the drilling operation, and meeting the diverse drilling processing needs of the bearing seat 37.

[0044] Two sets of fixing components 38 for fixing the bearing seat 37 are fixedly installed inside the carrier plate 36. One set of fixing components 38 is located on one side of the carrier plate 36. A circular hole 366 is opened on the surface of the carrier plate 36. A filter port 3661 is opened at the bottom of the circular hole 366. An arc groove A368 and a positioning hole 369 are opened on the surface of the carrier plate 36. A plate groove 367 is opened on the inner wall of the arc groove A368. The two sets of fixing components 38 can allow the bearing seat 37 to be clamped vertically or horizontally. The bearing seat 37 can not only drill holes on the upper surface, but also on the outer surface. The coolant generated during drilling can be discharged through the filter port 3661 to prevent the coolant from accumulating inside the circular hole 366. In contrast, when drilling holes, the existing bearing seat 37 has a single clamping method and cannot be flexibly clamped vertically or horizontally, resulting in drilling only on the upper surface and difficulty in drilling on the outer surface. In addition, the coolant generated during drilling is easy to accumulate in the circular hole 366 and cannot be discharged in time.

[0045] The fixing assembly 38 includes a fixing plate 381 fixedly mounted on the bottom of the circular hole 366, a rotating column 382 is movably provided on the surface of the fixing plate 381, a splint 383 is sleeved on the outer surface of the rotating column 382, ​​a gear A384 is fixedly mounted on the outer surface of the rotating column 382, ​​the splint 383 is located below the gear A384, and the rotating column 382 is provided with three groups, a toothed disc 385 is movably provided on the top of the circular hole 366, the toothed disc 385 is meshed with the gear A384, a short column 386 is fixedly mounted on the upper surface of the toothed disc 385, the short column 386 is movably connected to the arc groove A368, a baffle 387 is sleeved on the outer surface of the short column 386, the baffle 387 is slidably connected to the plate groove 367, a dial plate 388 is fixedly mounted on the top of the short column 386, a latch 389 is movably provided inside the dial plate 388, the latch 389 is adapted to the positioning hole 369, By rotating the short column 386, the three sets of clamps 383 can be rotated counterclockwise, thereby opening the slots on the surface of the fixed disk 381. At this time, the bearing seat 37 is placed into the slots of the fixed disk 381, and then the short column 386 is slid in the opposite direction to allow the gear plate 385 to drive the gear A384 to rotate with the clamp 383. At this time, one end of the clockwise rotating clamp 383 will clamp the bearing seat 37, and then the pin 389 is inserted into the positioning hole 369 through the dial plate 388 to fix the position of the short column 386, ensuring the stability of the clamp 383 clamping the bearing seat 37. In contrast, when drilling, the existing bearing seat 37 is cumbersome to install and disassemble, the clamping process is difficult to accurately control, and the stability after clamping is insufficient, which is prone to displacement during the drilling process, affecting the drilling accuracy and equipment operation stability.

[0046] The top cover 2 is fixedly mounted with a motor A21, the output shaft of the motor A21 is provided with a switching disk 22, the lower surface of the switching disk 22 is fixedly mounted with a connecting column 25, one end of the connecting column 25 is fixedly mounted with a working disk 23, the upper surface of the working disk 23 is fixedly mounted with a motor B24, the motor B24 is provided with two groups, one group of motor B24 output end is provided with a drill bit 6, the other group of motor B24 output end is provided with a fixing rod 26, the lower surface of the fixing rod 26 is fixedly mounted with a fixing plate 27, the lower surface of the fixing plate 27 is fixedly mounted with a grinding assembly 4, the grinding assembly 4 and the drill bit 6 are on the same horizontal line, and can be driven by the motor A21 Switch the drill bit 6 or the grinding component 4 to work. When the drill bit 6 finishes working, the motor A21 will rotate clockwise, and then the fixed rod 26 will rotate to the top of the bearing seat 37. Then the drill bit 6 that has been interchanged will be cleaned by the extended cleaning component 5. When grinding is completed, the motor A21 will rotate half a circle again to drill the next group. In contrast, when drilling, the existing bearing seat 37 cannot easily switch the drill bit 6 and the grinding component 4 to work. It is difficult to automatically clean the drill bit 6 after the work is completed, and the connection efficiency between different processes is low, which affects the continuity and operation efficiency of the overall processing flow.

[0047] The grinding assembly 4 includes a top plate 41 fixedly mounted on the lower surface of the fixed plate 27, a motor B42 fixedly mounted on the upper surface of the top plate 41, the motor B42 is also located inside the fixed rod 26, a drive shaft 43 is provided at the output end of the motor B42, a positioning plate 44 is movably mounted at one end of the drive shaft 43, a chassis 45 is fixedly mounted on the lower surface of the positioning plate 44, an annular groove 46 is provided on the outer surface of the chassis 45, a rectangular groove 47 is provided on the surface of the positioning plate 44, a support plate 49 is fixedly mounted on the surface of the annular groove 46, the upper surface of the support plate 49 is fixedly mounted on the lower surface of the top plate 41, a rotating plate 48 is sleeved on the outer surface of the drive shaft 43, an arc groove B481 is provided on the surface of the rotating plate 48, a sliding column 483 is movably provided inside the arc groove B481, a rectangular plate 482 is fixedly mounted on the lower surface of the sliding column 483, and the rectangular plate 482 is slidably connected to the rectangular groove 47. A grinding plate 484 is fixedly installed at one end of the shaping plate 482, and the grinding plate 484 is adapted to the annular groove 46. The rotation angle of the rotating plate 48 can be adjusted by driving the motor B42, and then the extension distance of the grinding plate 484 can be adjusted, so that the extension distance of the grinding plate 484 can be adjusted at will according to the size of the inner diameter of the bearing seat 37, so that the inner diameter of the bearing seat 37 can be perfectly ground. The grinding plate 484 is driven by the motor B42 to be able to move, so that it can adapt to the bearing seats 37 with different sizes of inner diameters for grinding. In contrast, when drilling a hole in the existing bearing seat 37, it is difficult to flexibly adjust the extension distance of the grinding plate 484 according to the size of the inner diameter of the bearing seat 37, and it is impossible to adapt to the bearing seats 37 with different inner diameters for precise grinding, resulting in poor adaptability of the grinding operation and difficulty in ensuring the inner diameter grinding effect of bearing seats 37 of different specifications.

[0048] Specifically, when the bearing seat 37 is installed, the short column 386 of the rotating fixing assembly 38 causes the toothed disc 385 to drive the three sets of gears A384 to rotate, thereby allowing the splint 383 to rotate counterclockwise to open the slot of the fixing disc 381. After the bearing seat 37 is inserted, the short column 386 is slid in the opposite direction to cause the splint 383 to rotate clockwise to clamp the bearing seat 37. The pin 389 is then inserted into the positioning hole 369 to fix the short column 386. At the same time, the coolant produced by drilling is discharged through the filter port 3661 at the bottom of the circular hole 366. Then, the electric telescopic rod A32 in the two sets of columns 31 on the surface of the bottom plate 3 is started to drive the translation plate A33 to rise and fall to adjust the height. The motor A35 on one side of the translation plate A33 drives the threaded rod A365 in the movable slot 34 to rotate, so that the sleeve plate B363 drives the carrier plate 36 to move horizontally on the translation plate A33. At the same time, the translation plates B36 on both sides of the carrier plate 36 The motor A35 on the other side drives the threaded rod A365 in the transverse groove 364, causing the sleeve plate A362 to drive the carrier plate 36 to move horizontally on the translation plate B361. After the bearing seat 37 reaches the position of the drill bit 6, the electric telescopic rod A32 will slowly rise to start drilling. When grinding, the motor A21 of the top cover 2 drives the switching disk 22 to rotate, and the grinding assembly 4 on the working disk 23 is rotated to the top of the bearing seat 37 through the connecting column 25. Then the motor B42 drives the drive shaft 43 to rotate, driving the rotating plate 48 to rotate in the rectangular groove 47 of the positioning plate 44. The arc groove B481 of the rotating plate 48 pushes the sliding column 483, causing the rectangular plate 482 to drive the grinding plate 484 to move in the annular groove 46 of the chassis 45, thereby adjusting the extension distance of the grinding plate 484 according to the inner diameter of the bearing seat 37, and performing fine grinding on the inner hole of the bearing seat 37.
