Description

Technical Field

[0001] The invention relates to the technical field of bearing manufacturing, in particular to a high-efficiency turning device for a bearing seat of a petroleum machinery. Background Art

[0002] In the field of petroleum machinery, the bearing seat is one of the key components, and its processing accuracy and quality are directly related to the performance and service life of the entire mechanical equipment. The traditional turning process of the bearing seat faces many difficulties.

[0003] During the turning process, a large amount of iron chips are easily attached to the outer wall of the tool. If they are not cleaned in time, these residual iron chips will be embedded in the surface of the workpiece when it is put into use again, seriously affecting the turning accuracy and reducing the product quality. The traditional method relies on manual cleaning of the tool, which is labor-intensive and has poor cleaning effect. Iron filings will remain on the inner wall of the bearing seat after turning. If they are not cleaned up, they cannot enter the subsequent process directly. In the past, special cleaning processes and equipment were often required, which further increased the complexity and time cost of the production process, delayed the overall production progress, and reduced production efficiency. When the tool is moved out of the bearing seat, due to the fixed spacing between the tools, it is easy to scratch and collide with the inner wall of the bearing seat, causing damage to the inner wall of the bearing seat, resulting in an increase in the product scrap rate and causing unnecessary economic losses to the company.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiments of the present invention like Figures 1 to 5 As shown, a high-efficiency turning device for a bearing seat of a petroleum machinery comprises a base 1, a first bracket 2, a second bracket 3, an electric drive shaft 4 and a tool 6, wherein 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 shaft 4 is driven and installed on a side of the second bracket 3 close to the first bracket 2, and the tool 6 is distributed in a ring array and slidably connected to the inside of the electric drive shaft 4; The outside of the electric drive shaft 4 is provided with a spacing adjustment component 5 for adjusting the spacing between the tools 6. The spacing adjustment component 5 includes a disc 51. The inside of the disc 51 is provided with slide grooves 52 distributed in a ring array. The tool 6 is slidably connected to the inside of the slide groove 52. A first annular plate 53 is slidably connected to the side of the disc 51 close to the electric drive shaft 4. A first spring 54 is fixedly connected to the first annular plate 53 and the disc 51 in a ring array. An annular tooth groove 55 is provided on the side of the electric drive shaft 4 close to the disc 51. An annular tooth plate 56 matching the annular tooth groove 55 is fixedly connected to the side of the first annular plate 53 close to the electric drive shaft 4.

[0020] 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.

[0021] When this embodiment is actually used: when the staff needs to adjust the spacing of the tools 6, the staff slides the first annular plate 53 toward the inside of the disc 51. At this time, the first spring 54 is squeezed and elastically contracts. After the first annular plate 53 moves, the annular tooth plate 56 on its outer wall disengages from the annular tooth groove 55 of the electric drive 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 tools 6 through the slide groove 52 opened inside it. After being squeezed, the tools 6 will slide inside the electric drive shaft 4, so that the spacing of the tools 6 is adjusted. After the spacing of the tools 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 toward the side close to the electric drive shaft 4, and 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 shaft 4, so that the spacing of the tools 6 can only be shortened but not extended.

[0022] When the spacing adjustment of the tool 6 is completed, the staff starts the electric drive shaft 4, the electric drive 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 screw 83, so that the disk 51 on the outer wall of the tool 6 applies a rotational force, and at the same time, the annular gear plate 56 and the annular gear groove 55 are tightly engaged, so that the tool 6 can maintain the tension of sliding around inside the electric drive shaft 4, so that the tool 6 turns the inner wall of the bearing seat.

[0023] like Figures 5 to 7 As shown, a retraction assembly 7 is arranged on the outside of the electric drive shaft 4, and the retraction assembly 7 includes a fixed seat 71 fixedly connected to the outer wall of the tool 6, and a first screw rod 72 is rotatably connected to the interior of the fixed seat 71, and the end of the first screw rod 72 close to the tool 6 is rotatably connected to the outer wall of the tool 6, and the end of the first screw rod 72 away from the outer wall of the tool 6 is fixedly connected to the second spring 76, and the outer wall of the first screw rod 72 is threadedly connected to a slider 73, and a slow-release cylinder 74 is fixedly connected between the slider 73 and the outer wall of the tool 6, and the second spring 76 is fixedly connected to the first round rod 75 at one end away from the first screw rod 72, and the outer wall of the first round rod 75 is symmetrically fixedly connected to a limiting plate 77, and the end of the first round rod 75 away from the second spring 76 is fixedly connected to a first gear 78.

[0024] The inside of the tool 6 is symmetrically slidably connected to the limit frame 79, and the two limit frames 79 are fixedly connected to the sides close to each other with a straight tooth plate 710. The inside of the tool 6 is rotatably connected to the first tooth ring 711, and the straight tooth plates 710 are meshed with the first tooth ring 711. The inner wall of the first tooth ring 711 is provided with a thread groove. A square rod 712 is fixedly connected between the fixed seat 71 and the outer wall of the tool 6. The outer wall of the square rod 712 is slidably connected to a vertical plate 713, and a third spring 714 is fixedly connected between the vertical plate 713 and the outer wall of the tool 6. A second round rod 715 is fixedly connected to one side of the bottom of the vertical plate 713 near the limit frame 79, and a protrusion adapted to the inner wall thread groove of the first gear ring 711 is fixedly connected to the outer wall of the second round rod 715. A second gear ring 716 is fixedly connected to the middle of the outer wall of the disk 51. A transmission chain 717 is transmission-connected between the first gears 78. A first cylinder 718 is symmetrically fixedly connected to the outer wall of the disk 51, and the output end of the first cylinder 718 squeezes the transmission chain 717 and makes the transmission chain 717 mesh with the second gear ring 716.

[0025] The second spring 76 is fixedly connected between the first round rod 75 and the first screw rod 72 . A shaft is rotatably connected between the first round rod 75 and the fixing seat 71 to keep the first round rod 75 and the fixing seat 71 in a coaxial state. The top of the slider 73 is coated with a silicone coating.

[0026] When the tool 6 rotates and the inner wall of the bearing seat is turned, the first bracket 2 will drive the bearing seat to move and make the tool 6 leave the inside of the bearing seat. In 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 screw rod 72 through the friction force. During the sliding process of the outer wall of the first screw rod 72, the slider 73 will be connected with the thread of the outer wall of the first screw rod 72 through the inner wall protrusion of the slider 73, driving the first screw rod 72 to rotate. The rotation of the first screw rod 72 drives the second spring 76 to rotate together. At this time, the first round rod 75 is limited by the limit frame 79 and the limit plate 77 and cannot rotate. Therefore, the second spring 76 will twist and generate torsion. When the slider 73 slides to form an extrusion on 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 elastically contracts due to the extrusion, and the vertical plate 713 moves with The second round rod 715 is moved to slide inside the tool 6. After the second round rod 715 slides, the first toothed ring 711 rotates and drives the spur plate 710 meshing with it to slide relatively. The spur plate 710 slides relatively and causes the two limit frames 79 to slide in opposite directions inside the tool 6. After the limit frame 79 moves, it is no longer engaged with the limit plate 77. After the first round rod 75 is no longer limited, the torsion force of the second spring 76 is released to drive the first round rod 75 to rotate. When the first round rod 75 rotates, it drives 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 thereto to rotate together. After the disk 51 rotates, the distance between the tool 6 and the cutter 6 is shortened through the slide groove 52, so that the tool 6 is no longer in contact with the inner wall of the bearing seat. When the tool 6 leaves the inside of the bearing seat, the distance between the tool 6 can be shortened, thereby avoiding the inner wall of the bearing seat from being damaged when the tool 6 slides out. When the distance between the tools 6 increases, the distance between the two first gears 78 increases, so that the transmission chain 717 is stretched straight. After the transmission chain 717 is stretched straight, it squeezes the first cylinder 718, causing the first cylinder 718 to shrink. When the distance between the tools 6 decreases, the first cylinder 718 stretches and pushes the transmission chain 717 to engage with the outer wall of the second gear ring 716, thereby ensuring that the transmission chain 717 is always in a state of meshing and transmission with the first gear 78 and the second gear ring 716.

[0027] When the tool 6 is moved out of the inner wall of the bearing seat, after the slider 73 slides on the first screw rod 72, the first gear 78 rotates and drives the disc 51 to rotate together, thereby shortening the spacing of the tool 6, ensuring that the tool 6 will increase the gap with the inner wall of the bearing seat when moving out, ensuring that the tool 6 will not contact the inner wall of the bearing seat when moving out and cause scratches on the inner wall of the bearing seat, and at the same time, by actively shortening the gap of the tool 6 when moving out, it can make it easier for the staff to remove the bearing seat and improve the turning efficiency of the bearing seat.

[0028] like Figures 8 to 9As shown, a cleaning assembly 8 is provided inside the electric drive shaft 4, and the cleaning assembly 8 includes a second gear 81 rotatably connected to the middle part of the electric drive shaft 4, and a second screw rod 83 is fixedly connected to the side of the second gear 81 away from the electric drive shaft 4, and the outer wall of the tool 6 is fixedly connected to a first tooth plate 82, the first tooth plate 82 is meshed with the second screw rod 83, and a cover plate 84 is fixedly connected to the end of the second screw rod 83 away from the electric drive shaft 4.

[0029] The outer wall of the second screw rod 83 is threadedly connected with a special-shaped scraper 85, which is adapted to the tool 6. The interior of the special-shaped scraper 85 is slidably connected with a scraper strip 86 distributed in an annular array. The middle part of the special-shaped scraper 85 is fixedly connected with an air storage bin 88. The outside of the air storage bin 88 is fixedly connected with a second cylinder 87 distributed in an annular array. The output end of the second cylinder 87 is fixedly connected to the inner wall of the scraper strip 86. The interior of the air storage bin 88 is slidably connected with a second annular plate 89. A convex rod is provided on the side of the second annular plate 89 close to the cover plate 84. The interior of the air storage bin 88 forms a closed space due to the buckling of the second annular plate 89.

[0030] A cleaning brush is fixedly connected to the outer wall of the scraper strip 86 , and the protruding rod on the surface of the second annular plate 89 abuts against the cover plate 84 .

[0031] In actual use of this embodiment: when the tool 6 is separated from the inside of the bearing seat and the spacing is shortened, the sliding of the tool 6 inside the electric drive shaft 4 will drive the second gear 81 to rotate together through the first tooth plate 82, and the rotation of the second gear 81 will drive the second screw rod 83 to rotate together. When the second screw rod 83 rotates, the special-shaped scraper 85 slides laterally on the outer wall of the second screw rod 83 under the action of the tool 6 limit. The special-shaped scraper 85 will scrape the outer wall of the tool 6 during the sliding process, so that the iron chips attached to the outer wall of the tool 6 are separated from the outer wall of the tool 6, thereby ensuring that the tool 6 will not cause the problem of weakening the turning effect due to the attachment of iron chips during subsequent use. When the outer wall of the second screw rod 83 slides to the cover plate 84, the second annular plate 89 is blocked by the cover plate 84 and slides toward the inside of the air storage bin 88. The air in the inner cavity of the air storage bin 88 is squeezed by the second annular plate 89 and fills into the inside of the second cylinder 87. The increase of air in the second cylinder 87 causes the second cylinder 87 to stretch and push the outer wall of the scraper 86 to fit the inner wall of the bearing seat. As the special-shaped scraper 85 rotates and moves laterally inside the bearing seat, the iron filings scattered on the bearing seat are cleaned to the outside of the bearing seat by the scraping action of the special-shaped scraper 85, so that after the turning is completed, there is no iron filings left inside the bearing seat, which is convenient for the subsequent processing.

[0032] By sliding the special-shaped scraper 85 on the second screw 83, the outer wall of the tool 6 can be scraped by the special-shaped scraper 85 after turning is completed, so that the iron filings attached to the tool 6 can be cleaned up in time after turning is completed, so that the staff does not need to clean the tool 6, thereby reducing the work intensity of the staff when the turning work is in progress; when the tool 6 moves out of the inner wall of the bearing seat, the special-shaped scraper 85 rotates and the scraper bar 86 slides out of the inside of the special-shaped scraper 85, so that the iron filings remaining on the inner wall of the bearing seat after turning can be cleaned out of the inside of the bearing seat by the scraping of the scraper bar 86, so that the bearing seat after turning can be put into subsequent production work without cleaning, thereby improving production efficiency.
