Description

Technical Field

[0001] The present invention relates to the technical field of bearing manufacturing, and particularly to an efficient turning device for a bearing housing of petroleum machinery. Background Art

[0002] In the field of petroleum machinery, as one of the key components, the machining accuracy and quality of the bearing housing are directly related to the performance and service life of the entire mechanical equipment. The traditional turning process of the bearing housing faces many problems.

[0003] During the turning process of the tool, a large amount of iron filings are likely to adhere to the outer wall of the tool. If not cleaned in time, when put into use again, these residual iron filings will embed into the surface of the workpiece, seriously affecting the turning accuracy and reducing the product quality. The traditional method relies on manual cleaning of the tool, which has a large labor intensity and poor cleaning effect;

[0004] Iron filings will also remain on the inner wall of the bearing housing after turning. If not cleaned thoroughly, it cannot directly enter the subsequent processes. In the past, it was often necessary to arrange additional special cleaning processes and equipment, further increasing the complexity and time cost of the production process, delaying the overall production progress, and reducing the production efficiency;

[0005] When the tool is removed from the bearing housing, due to the fixed tool spacing, it is easy to scrape and collide with the inner wall of the bearing housing, causing damage to the inner wall of the bearing housing and increasing the scrap rate of the product, bringing unnecessary economic losses to the enterprise.

[0006] Therefore, an efficient turning device for a bearing housing of petroleum machinery is proposed. Summary of the Invention

A convex block adapted to the threaded groove on the inner wall of the first toothed ring is fixedly connected to the outer wall of the second round rod. A second toothed ring is fixedly connected to the middle part of the outer wall of the disc. A transmission chain is connected between the first gears in a transmission manner. First cylinders are symmetrically fixedly connected to the outer wall of the disc. An output end of the first cylinder presses on the transmission chain and makes the transmission chain meshed with the second toothed ring.

[0012] Preferably, a cleaning assembly is provided inside the electric drive rotating shaft. The cleaning assembly includes a second gear rotatably connected to the middle part of the electric drive rotating shaft. A second lead screw is fixedly connected to one side of the second gear far from the electric drive rotating shaft. First tooth plates are fixedly connected to the outer walls of the tools.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. When the tool is moved out of the inner wall of the bearing seat, after the slider slides on the first lead screw, the first gear rotates and drives the disc to rotate together, so as to shorten the distance between the tools, ensure that the gap between the tool and the inner wall of the bearing seat will increase when the tool is moved out of the inner wall of the bearing seat, ensure that the tool will not contact the inner wall of the bearing seat when it is moved out, so as to avoid scratching the inner wall of the bearing seat. At the same time, by actively shortening the gap between the tools when moving out the tools, it is convenient for the staff to take out the bearing seat and improve the turning efficiency of the bearing seat.

[0019] 2. Through the sliding of the special-shaped scraper on the second lead screw, the outer wall of the tool can be scraped by the special-shaped scraper after the turning is completed, so that the iron filings attached to the tool can be cleaned in time after the turning is completed, so that the staff does not need to clean the tool, reducing the work intensity of the staff during the continuous turning work. When the tool is moved out of the inner wall of the bearing seat, the rotation of the special-shaped scraper and the sliding of the scraping bar out of the inside of the special-shaped scraper enable the iron filings remaining on the inner wall of the bearing seat after turning to be cleaned out of the inside of the bearing seat under the scraping of the scraping bar, so that the turned bearing seat can be put into the subsequent production work without cleaning, improving the production efficiency.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiments of the present invention

[0036] As Figures 1 to 5 shown, a high-efficiency turning device for a bearing seat of a petroleum machinery includes a base 1, a first bracket 2, a second bracket 3, an electric drive rotating shaft 4, and a tool 6. The second bracket 3 is fixedly connected to the top of the base 1, the first bracket 2 is slidably connected to the top of the base 1, the electric drive rotating shaft 4 is drivingly installed on one side of the second bracket 3 close to the first bracket 2, and the tools 6 are slidably connected to the inside of the electric drive rotating shaft 4 in an annular array distribution.

[0037] A spacing adjustment assembly 5 for adjusting the spacing between the tools 6 is arranged outside the electric drive rotating shaft 4. The spacing adjustment assembly 5 includes a disc 51. A plurality of sliding grooves 52 are arranged in an annular array distribution inside the disc 51. The tools 6 are slidably connected to the inside of the sliding grooves 52. A first annular plate 53 is slidably connected to one side of the disc 51 close to the electric drive rotating shaft 4. A plurality of first springs 54 are fixedly connected between the first annular plate 53 and the disc 51 in an annular array distribution. An annular tooth groove 55 is arranged on one side of the electric drive rotating shaft 4 close to the disc 51. An annular tooth plate 56 adapted to the annular tooth groove 55 is fixedly connected to one side of the first annular plate 53 close to the electric drive rotating shaft 4.

[0038] The annular tooth groove 55 and the annular tooth plate 56 are in a ratchet shape. When the annular tooth plate 56 and the annular tooth groove 55 are engaged, the disc 51 can only rotate in one direction.

[0039] In actual operation of this embodiment: when the staff needs to adjust the spacing of the tool 6, the staff slides the first annular plate 53 towards the inside of the disc 51. At this time, the first spring 54 is squeezed and elastically contracted. After the first annular plate 53 moves, the annular tooth plate 56 on its outer wall disengages from the annular tooth groove 55 inside the electric drive rotating shaft 4, so that the annular tooth plate 56 and the annular tooth groove 55 are no longer engaged. At this time, the staff rotates the disc 51. After the disc 51 rotates, it will squeeze the tool 6 through the chute 52 opened inside it. After the tool 6 is squeezed, it will slide inside the electric drive rotating shaft 4, so that the spacing of the tool 6 is adjusted. After the spacing of the tool 6 is adjusted, the staff stops squeezing the first annular plate 53. The first spring 54 rebounds and pushes the first annular plate 53 to move towards the side close to the electric drive rotating shaft 4. The annular tooth plate 56 is re-engaged with the annular tooth groove 55. After the annular tooth groove 55 and the annular tooth plate 56 are engaged, the disc 51 can only rotate unidirectionally outside the electric drive rotating shaft 4, so that the spacing of the tool 6 can only be shortened and cannot be extended.

[0040] After the spacing of the tool 6 is adjusted, the staff starts the electric drive rotating shaft 4. The electric drive rotating shaft 4 rotates and drives the tool 6 to rotate together. The centrifugal force generated when the tool 6 rotates will cause the tool 6 to move away from the second lead screw 83, apply a rotating force to the disc 51 on the outer wall of the tool 6, and at the same time make the annular tooth plate 56 and the annular tooth groove 55 tightly engaged, so that the tool 6 can maintain the tension to slide around inside the electric drive rotating shaft 4, so that the tool 6 can turn the inner wall of the bearing seat.

[0041] As Figures 5 to 7 shown, a contraction assembly 7 is provided outside the electric drive rotating shaft 4. The contraction assembly 7 includes a fixed seat 71 fixedly connected to the outer wall of the tool 6. A first lead screw 72 is rotatably connected through the inside of the fixed seat 71. One end of the first lead screw 72 close to the tool 6 is rotatably connected to the outer wall of the tool 6. One end of the first lead screw 72 far from the outer wall of the tool 6 is fixedly connected with a second spring 76. A slider 73 is threadedly connected to the outer wall of the first lead screw 72. A slow-release cylinder 74 is fixedly connected between the slider 73 and the outer wall of the tool 6. One end of the second spring 76 far from the first lead screw 72 is fixedly connected with a first round rod 75. Limiting plates 77 are symmetrically fixedly connected to the outer wall of the first round rod 75. One end of the first round rod 75 far from the second spring 76 is fixedly connected with a first gear 78.

[0042] The inside of the tool 6 is symmetrically and slidably connected with a limit frame 79. On the side of the two limit frames 79 close to each other, a straight tooth plate 710 is fixedly connected. Inside the tool 6, a first tooth ring 711 is rotatably connected. The straight tooth plates 710 are all meshed with the first tooth ring 711. A threaded groove is provided on the inner wall of the first tooth ring 711. A square rod 712 is fixedly connected between the fixed seat 71 and the outer wall of the tool 6. A vertical plate 713 is slidably connected to the outer wall of the square rod 712. A third spring 714 is fixedly connected between the vertical plate 713 and the outer wall of the tool 6. On the side of the bottom of the vertical plate 713 close to the limit frame 79, a second round rod 715 is fixedly connected. A convex block adapted to the threaded groove on the inner wall of the first tooth ring 711 is fixedly connected to the outer wall of the second round rod 715. In the middle of the outer wall of the disc 51, a second tooth ring 716 is fixedly connected. A transmission chain 717 is connected between the first gears 78. On the outer wall of the disc 51, first cylinders 718 are symmetrically fixedly connected. The output ends of the first cylinders 718 press on the transmission chain 717 and make the transmission chain 717 mesh with the second tooth ring 716.

[0043] The second spring 76 is fixedly connected between the first round rod 75 and the first lead screw 72. A shaft rod is rotatably connected between the first round rod 75 and the fixed seat 71 to keep the first round rod 75 and the fixed seat 71 coaxial. A silica gel coating is applied to the top of the slider 73.

[0044] In actual operation of this embodiment: When the tool 6 rotates and finishes turning the inner wall of the bearing seat, the first bracket 2 will drive the bearing seat to move and make the tool 6 disengage from the inside of the bearing seat. During the process of increasing the distance between the second bracket 3 and the first bracket 2, the inner wall of the bearing seat will drive the slider 73 to slide on the outer wall of the first lead screw 72 through friction. During the process of the slider 73 sliding on the outer wall of the first lead screw 72, the inner wall convex block of the slider 73 will be threadedly connected to the outer wall of the first lead screw 72, driving the first lead screw 72 to rotate. The rotation of the first lead screw 72 drives the second spring 76 to rotate together. At this time, the first round rod 75 is restricted by the clamping of the limiting frame 79 and the limiting plate 77 and cannot rotate. Therefore, the second spring 76 will twist and generate torsion. When the slider 73 slides to squeeze the vertical plate 713, the vertical plate 713 will slide on the outer wall of the square rod 712. At the same time, the third spring 714 will elastically contract due to being squeezed. The movement of the vertical plate 713 drives the second round rod 715 to slide inside the tool 6 together. After the second round rod 715 slides, it will cause the first toothed ring 711 to rotate and drive the straight toothed plate 710 meshing with it to slide relatively. The relative sliding of the straight toothed plate 710 causes the two limiting frames 79 to slide in opposite directions inside the tool 6. After the limiting frame 79 moves, it no longer clamps with the limiting plate 77. After the first round rod 75 is no longer restricted, the torsion of the second spring 76 is released to drive the first round rod 75 to rotate. When the first round rod 75 rotates, it will drive the second toothed ring 716 to rotate together through the first gear 78 and the transmission chain 717. The rotation of the second toothed ring 716 drives the disk 51 fixed to it to rotate together. After the disk 51 rotates, it will shorten the distance between the tools 6 through the sliding groove 52, so that the tool 6 no longer fits the inner wall of the bearing seat, so that when the tool 6 disengages from the inside of the bearing seat, the distance between the tools 6 can be shortened, avoiding sliding damage to the inner wall of the bearing seat when the tool 6 slides out;

[0045] When the distance between the tools 6 increases, the increase in the distance between the two first gears 78 makes the transmission chain 717 straighten. After the transmission chain 717 straightens, it squeezes the first air cylinder 718, causing the first air cylinder 718 to contract. When the distance between the tools 6 shortens, the first air cylinder 718 extends and pushes the transmission chain 717 to engage with the outer wall of the second toothed ring 716, so as to ensure that the transmission chain 717 is always in a state of meshing and driving with the first gear 78 and the second toothed ring 716.

[0046] When the tool 6 moves out of the inner wall of the bearing seat, after the slider 73 slides on the first lead screw 72, the first gear 78 rotates and drives the disk 51 to rotate together, so as to shorten the distance between the tools 6, ensuring that the tool 6 will increase the gap with the inner wall of the bearing seat when moving out of the inner wall of the bearing seat, ensuring that the tool 6 will not contact the inner wall of the bearing seat when moving out and cause scratching of the inner wall of the bearing seat. At the same time, by actively shortening the gap between the tools 6 when moving out the tool 6, it can facilitate the staff to take out the bearing seat and improve the turning efficiency of the bearing seat.

[0047] AsFigures 8 to 9 As shown in the figure, a cleaning assembly 8 is arranged inside the electric drive rotating shaft 4. The cleaning assembly 8 includes a second gear 81 rotatably connected to the middle of the electric drive rotating shaft 4. A second lead screw 83 is fixedly connected to the side of the second gear 81 away from the electric drive rotating shaft 4. First toothed plates 82 are fixedly connected to the outer walls of the cutting tools 6. The first toothed plates 82 are meshed with the second lead screw 83. A cover plate 84 is fixedly connected to the end of the second lead screw 83 away from the electric drive rotating shaft 4.

[0048] An irregular scraping plate 85 is threadedly connected to the outer wall of the second lead screw 83. The irregular scraping plate 85 is adapted to the cutting tool 6. Scraping bars 86 are slidably connected to the inside of the irregular scraping plate 85 in an annular array. A gas storage chamber 88 is fixedly connected to the middle of the irregular scraping plate 85. Second cylinders 87 are fixedly connected to the outside of the gas storage chamber 88 in an annular array. The output ends of the second cylinders 87 are fixedly connected to the inner walls of the scraping bars 86. A second annular plate 89 is slidably connected to the inside of the gas storage chamber 88. A convex rod is arranged on the side of the second annular plate 89 close to the cover plate 84. A closed space is formed inside the gas storage chamber 88 due to the buckling of the second annular plate 89.

[0049] A cleaning brush is fixedly connected to the outer wall of the scraping bar 86. The convex rod on the surface of the second annular plate 89 abuts against the cover plate 84.

[0050] In actual operation of this embodiment: When the cutting tool 6 disengages from the inside of the bearing seat and the distance is shortened, the sliding of the cutting tool 6 inside the electric drive rotating shaft 4 will drive the second gear 81 to rotate together through the first toothed plate 82. The rotation of the second gear 81 drives the second lead screw 83 to rotate together. When the second lead screw 83 rotates, the irregular scraping plate 85 slides horizontally on the outer wall of the second lead screw 83 under the limitation of the cutting tool 6. During the sliding process of the irregular scraping plate 85, it will scrape the outer wall of the cutting tool 6, so that the iron filings attached to the outer wall of the cutting tool 6 are separated from the outer wall of the cutting tool 6, thus ensuring that the cutting effect of the cutting tool 6 will not be weakened due to the attachment of iron filings during subsequent use. When the irregular scraping plate 85 slides to the cover plate 84 on the outer wall of the second lead screw 83, the second annular plate 89 is blocked by the cover plate 84 and slides into the inside of the gas storage chamber 88. The air in the inner cavity of the gas storage chamber 88 is squeezed by the second annular plate 89 and fills into the inside of the second cylinder 87. The increase in the air inside the second cylinder 87 causes the second cylinder 87 to extend and push the outer wall of the scraping bar 86 to fit against the inner wall of the bearing seat. As the irregular scraping plate 85 rotates and moves horizontally inside the bearing seat, the iron filings scattered in the bearing seat are cleaned to the outside of the bearing seat under the scraping action of the irregular scraping plate 85, so that after the turning of the bearing seat is completed, there is no iron filing residue inside, which is convenient for subsequent processing.

[0051] By sliding the special-shaped scraper 85 on the second lead screw 83, the outer wall of the tool 6 can be scraped by the special-shaped scraper 85 after turning, so that the iron chips attached to the tool 6 can be cleaned in time after turning, enabling the staff to avoid cleaning the tool 6 and reducing the work intensity of the staff during continuous turning. When the tool 6 moves out of the inner wall of the bearing block, the rotation of the special-shaped scraper 85 and the scraping strip 86 slides out of the inside of the special-shaped scraper 85, so that the iron chips remaining on the inner wall of the bearing block after turning can be cleaned out of the inside of the bearing block under the scraping of the scraping strip 86, enabling the turned bearing block to be put into subsequent production work without cleaning and improving production efficiency.
