Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, specifically to an automatic feeding and annealing device for wind power bearings. Background Technology

[0002] Bearings used in wind power equipment require high strength, and high-strength bearings need to be annealed during processing. Annealing is a metal heat treatment process that involves slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize dimensions, reduce deformation and cracking tendency, refine grains, adjust microstructure, and eliminate microstructural defects.

[0003] For example, Chinese Patent Publication No. CN118127306B discloses an annealing furnace for machining the outer ring of a bearing, including an annealing furnace body and a movable door. A movable plate is horizontally slidably arranged inside the annealing furnace body along its length direction, and several upper support rods are horizontally arranged on the side of the movable plate near the movable door. The upper support rods are rotatably connected to the movable plate, and several partitions are evenly spaced on the outer wall of the upper support rods along their length direction. Lower support rods are movably arranged directly below each of the upper support rods. A linear drive mechanism is provided on the side of the movable plate away from the movable door to drive the several lower support rods to slide up and down synchronously. The upper and lower support rods are used for internal support and positioning of the outer ring of the bearing. A rotary drive mechanism is provided on the annealing furnace body to drive the upper support rods to rotate.

[0004] In the aforementioned cited document, the outer ring of the bearing is fitted onto the outer walls of the upper and lower support rods, resulting in more uniform heating, better annealing effect, and higher working efficiency.

[0005] However, during the annealing process of the bearing outer ring, after the upper and lower support rods support the bearing outer ring and position it between the two sets of partitions, the bearing outer ring rotates due to friction caused by the rotation of the support rods. As a result, the two sides of the bearing outer ring rub against each other and tend to stick to the two sets of partitions, causing the sides of the bearing outer ring to not be heated evenly, thus resulting in uneven annealing of the bearing outer ring. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic feeding annealing device for wind power bearings, which positions the bearing in the middle of the annealing furnace partition, thereby avoiding uneven heating during annealing caused by the outer ring of the bearing being in contact with the side of the partition.

Guide grooves are opened at both ends of the furnace box near the bottom. The transmission rod movably extends through the guide grooves into the inner cavity of the corresponding fixed plate, and the extension end of the stroke cylinder is fixedly connected to the bottom of the corresponding fixed plate.

[0009] Preferably, the fixing rod is fixedly installed on the inner wall of the furnace box on the side away from the movable chamber door, the support tube is slidably sleeved on the fixing rod, the outer circumference of the support tube is provided with movable grooves at equal intervals, the output end of the air pump is fixedly connected to the air guide pipe, and the air guide pipe movably penetrates into the inner wall of the corresponding support tube.

[0010] Preferably, the end of the slide plate slides in the corresponding movable groove, and the adjacent surfaces of the two sets of adjacent side blocks are provided with equally spaced grooves, and the slider slides in the inner wall of the groove.

[0011] Preferably, a telescopic airbag is fixedly installed on the inner wall of the slide near the inner diameter end. The telescopic end of the telescopic airbag is fixedly connected to the corresponding end of the slider. Two sets of adjacent surfaces of the corresponding sliders are respectively fixedly installed with abutting springs. The end of the connecting block is fixedly connected to the end of the abutting spring. The end of the connecting block away from the abutting spring is equipped with a first sliding ball through a ball sleeve for universal rolling.

[0012] Preferably, the air storage cylinder is fixedly installed on the side wall of the middle abutment block, a piston plate is slidably connected inside the air storage cylinder, a connecting pipe is fixedly connected to the side of the sliding plate and the corresponding input end of the telescopic airbag, a T-shaped through groove is opened in the middle of the piston plate, and the T-shaped through groove at the end of the piston plate is connected to the corresponding connecting pipe.

[0013] Preferably, ball bearings are fixedly installed at both ends of the transmission rod, the support block is fixedly installed in the inner wall of the mounting base, the first wedge is fixedly installed on the top of the corresponding support block, and each set of the first wedge corresponds to the second wedge at the top.

[0014] Preferably, the outer diameter of the ball bearing is fixedly installed on the inner wall of the corresponding fixed plate, and synchronous pulleys are fixedly sleeved on the two sets of transmission rods near the servo motor. The servo motor is fixedly installed on the outer wall of the corresponding fixed plate, and the synchronous pulley is also fixedly installed on the output end of the servo motor. A synchronous belt is fixedly sleeved between adjacent synchronous pulleys, and transmission wheels are fixedly installed at equal intervals on the outside of the transmission rod.

[0015] Preferably, the outer wall of the central abutment block is provided with equally spaced sealing cavities, the piston rod has a T-shaped side profile, the piston rod slides in the inner wall of the corresponding sealing cavity, and a return spring is fixedly installed at the bottom end of the piston rod in the inner wall of the sealing cavity.

[0016] Preferably, the central abutment block is provided with an air passage, and the air guide tube is connected to the multiple sets of sealing cavities through the air passage.

[0017] Compared with the prior art, the beneficial effects of the present invention are: In this invention, after the outer ring of the bearing is placed on the central abutment block, under the action of gravity, the outer wall of the bearing contacts the outer surface of the second sliding ball. Air is injected into the air passages inside the multiple sets of central abutment blocks through an air pump and an air guide pipe. The gas enters the sealed cavity and pushes the piston rod to move outward. This causes the second sliding ball at the end of the piston rod to expand against the outer ring of the bearing and press against the outer wall of the support tube. This achieves a small area of ​​contact between the multiple sets of second sliding balls and the outer ring of the bearing, reducing the contact area with the inner diameter of the bearing. This makes the inner wall of the bearing outer ring heat more evenly during annealing.

[0018] In this invention, when the extension and retraction end of the stroke cylinder drives the two sets of fixed plates to move upward, multiple sets of first wedges on the mounting base abut against the corresponding second wedges. This causes the two sets of adjacent side abutments to move closer to each other along the movable groove via the sliding plate in the inner diameter. At this time, the piston plate end of the air storage cylinder on the side of the corresponding sliding plate abuts against each other. After compressing the internal gas, it is transmitted to the corresponding telescopic air bladder through the inner cavity of the piston plate. After the telescopic air bladder extends and retracts inside the slide groove, the sliding distance of the slider in the slide groove is adapted to the two side walls of the bearing. At this time, the first sliding ball on the connecting block abuts against the two side walls of the bearing under the cooperation of the abutment spring. This achieves centered abutment against the two sides of the bearing outer ring on the middle abutment block, thereby avoiding the problem that the bearing outer ring is not uniformly heated when it rotates and comes into contact with the side abutments positioned on both sides.

[0019] In this invention, after the stroke cylinder drives the mounting base and the transmission rod in the inner wall to approach the corresponding support tube above, the ends of the two sets of transmission rods are synchronously driven by the synchronous pulley and the synchronous belt. This causes multiple sets of transmission pulleys outside the transmission rod to rub and drive the outer ring of the bearing positioned on the middle block. The outer wall of the bearing slides on the first sliding ball, while the outer side of the bearing outer ring slides on the second sliding ball. This allows the outer ring of the bearing to be uniformly heated and annealed after rotating inside the furnace. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1:

[0023] This embodiment describes an automatic feeding annealing device for processing wind power bearings, such as... Figures 1-8 As shown, it includes a furnace box 100, a synchronous pulley 55, a support tube 600, a fixing rod 61, and also includes: The stroke cylinder 200 is fixedly installed at the middle of both ends of the furnace box 100; Air pump 300 is fixedly installed on the outer wall of furnace box 100; The servo motor 400 is installed on the outer wall of the furnace box 100 on the side away from the air pump 300; The transmission rod 500 is installed in the inner cavity of the furnace box 100. A mounting base 51 is provided on the outside of the transmission rod 500. Support blocks 53 and first wedge blocks 54 are installed at equal intervals on the inner wall of the mounting base 51. A side abutment block 700 is movably installed on the outer circumference of the support tube 600. A second wedge block 71 is fixedly installed at the bottom of the side abutment block 700. A sliding plate 72 is fixedly installed on the inner diameter of the side abutment block 700. A slider 74, a connecting block 75 and a telescopic airbag 78 are respectively provided on the inner side of two adjacent side abutment blocks 700. An air storage cylinder 76 is also provided in the inner wall of the support tube 600.

[0024] The furnace box 100 has a movable door 11 installed at the opening near the servo motor 400. Fixed plates 12 are movably installed at both ends of the furnace box 100 near the bottom. Guide grooves 13 are opened at both ends of the furnace box 100 near the bottom. The transmission rod 500 extends through the guide groove 13 and into the inner cavity of the corresponding fixed plate 12. The extension end of the stroke cylinder 200 is fixedly connected to the bottom of the corresponding fixed plate 12. The support tube 600 is pulled out from the outside of the fixed rod 61 near the movable door 11. In this way, the wind turbine bearings can be placed between two adjacent sets of side abutments 700. The support tube 600 is reset by sliding into the outside of the fixed rod 61, so that multiple sets of wind turbine bearings are placed outside the support tube 600 and annealed inside the furnace box 100.

[0025] Among them, the fixed rod 61 is fixedly installed on the inner wall of the furnace box 100 away from the movable chamber door 11. The support tube 600 is slidably sleeved on the fixed rod 61. Movable grooves 60 are evenly spaced on the outer circumference of the support tube 600. The output end of the air pump 300 is fixedly connected to the air guide tube 31, which movably passes through the inner wall of the corresponding support tube 600. The end of the sliding plate 72 slides in the corresponding movable groove 60. The adjacent surfaces of two sets of adjacent side blocks 700 are evenly spaced with sliding grooves 73. The slider 74 slides in the inner wall of the sliding groove 73. A telescopic airbag 78 is fixedly installed on the inner wall of the sliding groove 73 near the inner diameter. The telescopic end of the telescopic airbag 78 is fixedly connected to the end of the corresponding slider 74. The two sets of corresponding sliders Adjacent surfaces 74 are fixedly installed with contact springs 752. The end of the connecting block 75 is fixedly connected to the end of the contact spring 752. The end of the connecting block 75 away from the contact spring 752 is equipped with a first sliding ball 751 through a ball sleeve. Air pump 300 and air guide pipe 31 inject air into the air passage 85 inside the multiple sets of middle contact blocks 800. The gas enters the sealing cavity 81 and presses the end of the piston rod 82 outward. This causes the second sliding ball 83 at the end of the piston rod 82 to expand against the outer ring of the bearing and press against the outer wall of the support tube 600. This achieves a small area of ​​contact between the three sets of second sliding balls 83 and the outer ring of the bearing, reducing the contact area with the inner diameter of the bearing, so that the inner wall of the bearing outer ring is heated more evenly during annealing.

[0026] Among them, the air storage cylinder 76 is fixedly installed on the side wall of the middle abutment block 800. A piston plate 77 is slidably connected inside the air storage cylinder 76. A connecting pipe is fixedly connected to the side of the sliding plate 72 and the corresponding input end of the telescopic airbag 78. A T-shaped through groove is opened in the middle of the piston plate 77. The T-shaped through groove at the end of the piston plate 77 is connected to the corresponding connecting pipe. Ball bearings 52 are fixedly installed at both ends of the transmission rod 500. The support block 53 is fixedly installed in the inner wall of the above-mentioned mounting base 51. The first wedge block 54 is fixedly installed on the top of the corresponding support block 53. Each set of first wedge blocks 54 corresponds to the second wedge block 71 at the top. When the extension end of the stroke cylinder 200 drives the two sets of fixed plates 12 to move upward, the mounting base... Multiple sets of first wedges 54 on 51 abut against the corresponding second wedges 71, causing two sets of adjacent side abutments 700 to move closer to each other along the movable groove 60 via the inner diameter sliding plate 72. At this time, the ends of the piston plates 77 of the air storage cylinders 76 on the side of the corresponding sliding plate 72 abut against each other. After compressing the internal gas, it is transmitted to the corresponding telescopic air bladder 78 through the inner cavity of the piston plate 77. After the telescopic air bladder 78 extends and retracts inside the slide groove 73, it causes the corresponding slider 74 to expand outward along the slide groove 73. This causes the first slider 751 to expand to the outer ring of the bearing and then abut against the outer ring of the bearing. This achieves centered abutment against both sides of the outer ring of the bearing on the middle abutment block 800.

[0027] In this embodiment, the side abutments 700 evenly spaced on the support tube 600 are used to abut the outer ring of the bearing from the side. The sliding plate 72 and the middle abutment 800 in the inner wall of the support tube 600 are movably sleeved on the fixed rod 61. The support tube 600 is pulled out from the outside of the fixed rod 61 near the movable chamber door 11. In this way, the wind turbine bearing can be placed between two adjacent sets of side abutments 700. After the support tube 600 is reset by sliding into the outside of the fixed rod 61, the movable chamber door 11 abuts against the fixed rod 61 and the end of the support tube 600. In this way, multiple sets of wind turbine bearings are placed outside the support tube 600 and annealed inside the furnace box 100.

[0028] In this embodiment, after the bearing outer ring is placed on the central abutment block 800, under the action of gravity, the outer wall of the bearing contacts the outer surface of the second sliding ball 83. The air pump 300 and the air guide pipe 31 inject air into the air passages 85 inside the multiple sets of central abutment blocks 800. The gas enters the sealing cavity 81 and presses the end of the piston rod 82 outward. This causes the second sliding ball 83 at the end of the piston rod 82 to expand against the bearing outer ring and press against the outer wall of the support tube 600. This achieves a small area of ​​contact between the three sets of second sliding balls 83 and the bearing outer ring, reducing the contact area with the bearing inner diameter, and making the inner wall of the bearing outer ring more evenly heated during annealing. Example 2:

[0029] Based on Example 1, this example introduces an automatic feeding annealing device for wind power bearing processing, such as... Figures 3-8 As shown, it includes: a central abutment block 800, which is fixedly installed in the inner wall of the support tube 600; piston rods 82 are evenly spaced on the outer circumference of the central abutment block 800; and a second sliding ball 83 is rolled on the outer end of the piston rod 82 through a ball sleeve.

[0030] Among them, the outer diameter of the ball bearing 52 is fixedly installed on the inner wall of the corresponding fixed plate 12. The two sets of transmission rods 500 are respectively fixedly fitted with synchronous pulleys 55 at the end near the servo motor 400. The servo motor 400 is fixedly installed on the outer wall of the corresponding fixed plate 12. The output end of the servo motor 400 is also fixedly fitted with synchronous pulleys 55. A synchronous belt 56 is fixedly fitted between adjacent synchronous pulleys 55. Transmission wheels 57 are fixedly installed at equal intervals on the outside of the transmission rods 500. The ends of the two sets of transmission rods 500 are synchronously driven by the synchronous pulleys 55 and the synchronous belt 56. In this way, the multiple sets of transmission wheels 57 on the outside of the transmission rods 500 will rub and drive the outer ring of the bearing positioned on the middle abutment block 800.

[0031] The central abutment block 800 has equally spaced sealing cavities 81 on its outer wall. The piston rod 82 has a T-shaped side profile and slides within the inner wall of the corresponding sealing cavity 81. A return spring 84 is fixedly installed at the bottom of the piston rod 82 and within the inner wall of the sealing cavity 81. The central abutment block 800 has an air passage 85 inside. The air guide pipe 31 is connected to the multiple sealing cavities 81 through the air passage 85. The air pump 300 and the air guide pipe 31 inject air into the air passages 85 inside the multiple central abutment blocks 800. The gas enters the sealing cavity 81 and presses the end of the piston rod 82 outward. This causes the second sliding ball 83 at the end of the piston rod 82 to expand against the outer ring of the bearing and press against the outer wall of the support tube 600. This achieves a small contact area between the three sets of second sliding balls 83 and the outer ring of the bearing, reducing the contact area with the inner diameter of the bearing and making the inner wall of the bearing outer ring more evenly heated during annealing.

[0032] In this embodiment, when the extension end of the stroke cylinder 200 drives the two sets of fixed plates 12 to move upward, multiple sets of first wedges 54 on the mounting base 51 abut against the corresponding second wedges 71. This causes the two sets of adjacent side abutments 700 to move closer to each other along the movable groove 60 via the inner diameter sliding plate 72. At this time, the ends of the piston plates 77 of the air storage cylinder 76 on the side of the corresponding sliding plate 72 abut against each other. After compressing the internal gas, it is transmitted to the corresponding telescopic air bladder 78 through the inner cavity of the piston plate 77. The telescopic air bladder 78 extends and retracts inside the slide groove 73. The sliding distance of the slider 74 in the slide groove 73 is adapted to the two side walls of the bearing. At this time, the first sliding ball 751 on the connecting block 75, with the cooperation of the abutment spring 752, abuts against the two side walls of the bearing. This achieves centered abutment against the two sides of the bearing outer ring on the middle abutment block 800, thereby avoiding the problem that the bearing outer ring is not uniformly heated when it rotates and is in contact with the side abutments 700 positioned on both sides.

[0033] In this embodiment, after the stroke cylinder 200 drives the mounting base 51 and the transmission rod 500 in the inner wall to approach the corresponding support tube 600 above, the ends of the two sets of transmission rods 500 are synchronously driven by the synchronous pulley 55 and the synchronous belt 56. This causes multiple sets of transmission pulleys 57 outside the transmission rod 500 to rub and drive the outer ring of the bearing positioned on the middle abutment block 800. The outer wall of the bearing slides on the first sliding ball 751, while the outer side of the bearing outer ring slides on the second sliding ball 83. This allows the outer ring of the bearing to be uniformly heated and annealed after rotating inside the furnace box 100.

[0034] Working principle: When the wind turbine bearing is annealed, the movable chamber door 11 is opened first. Then, the support tube 600 is pulled out from the outside of the fixed rod 61 near the movable chamber door 11. This allows the wind turbine bearing to be placed between two adjacent sets of side abutments 700. After the support tube 600 is slid into the outside of the fixed rod 61 and reset, the movable chamber door 11 abuts against the fixed rod 61 and the end of the support tube 600. This allows multiple sets of wind turbine bearings to be placed outside the support tube 600 and annealed inside the furnace box 100.

[0035] After the outer ring of the bearing is placed on the middle abutment block 800, under the action of gravity, the outer wall of the bearing contacts the outer surface of the second sliding ball 83. The air pump 300 and the air guide pipe 31 inject air into the air passages 85 inside the multiple sets of middle abutment blocks 800. The gas enters the sealing cavity 81 and presses the end of the piston rod 82 outward. This causes the second sliding ball 83 at the end of the piston rod 82 to expand the outer ring of the bearing and press it tightly against the outer wall of the support tube 600.

[0036] When the extension end of the stroke cylinder 200 is controlled by the control switch to move the two sets of fixed plates 12 upward, the multiple sets of first wedges 54 on the mounting base 51 abut against the corresponding second wedges 71. This causes the two sets of adjacent side abutments 700 to move closer to each other along the movable groove 60 through the inner diameter sliding plate 72. At this time, the end of the piston plate 77 of the air storage cylinder 76 on the side of the corresponding sliding plate 72 abuts against each other. After compressing the internal gas, it is transmitted to the corresponding telescopic air bladder 78 through the inner cavity of the piston plate 77. After the telescopic air bladder 78 extends and retracts inside the slide groove 73, it expands the corresponding slider 74 outward along the slide groove 73. The sliding distance of the slider 74 in the slide groove 73 is adapted to the two side walls of the bearing. At this time, the first sliding ball 751 on the connecting block 75 abuts against the two side walls of the bearing with the cooperation of the abutment spring 752.

[0037] After the stroke cylinder 200 drives the mounting base 51 and the transmission rod 500 in the inner wall to approach the corresponding support tube 600 above, the ends of the two sets of transmission rods 500 are synchronously driven by the synchronous pulley 55 and the synchronous belt 56. This causes multiple sets of transmission pulleys 57 outside the transmission rod 500 to rub and drive the outer ring of the bearing positioned on the middle abutment block 800. The outer wall of the bearing slides on the first sliding ball 751, while the outer side of the bearing outer ring slides on the second sliding ball 83. This allows the outer ring of the bearing to be uniformly heated and annealed after rotating inside the furnace box 100.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
