Description

Technical Field

[0001] The present invention belongs to the technical field of internal gear ring processing, and particularly relates to a processing device and a processing technology for an internal gear ring of a wind power gearbox. Background Art

[0002] The wind power gearbox is one of the key components in a wind power generation unit. Its main function is to convert the low-speed and high-torque energy generated by the wind turbine under the action of wind into the high-speed and low-torque energy suitable for the generator. In this process, the internal gear ring, as an important part of the gearbox, is usually used in cooperation with the planetary gear train. It plays a role in supporting the planetary gears and participating in power transmission in the wind power gearbox, transmitting power and adjusting the speed ratio. The internal gear ring is located outside the planet carrier and surrounds one or more groups of planetary gears. In order to withstand huge mechanical loads and dynamic stresses, the internal gear ring is usually made of high-strength alloy steel and undergoes strict heat treatment processes to improve hardness and wear resistance. Moreover, the tooth surface of the internal gear ring needs to be subjected to high-precision grinding to ensure accurate tooth shape and high surface finish, thereby reducing frictional losses and noise during operation. In order to perform high-precision grinding on the internal gear ring, it is necessary to ensure the coaxiality between the internal gear ring workpiece and the machine tool workbench. In the prior art, general internal gear processing is single-piece processing, and it is necessary to manually correct the coaxiality between the workpiece and the machine tool workbench and mechanically manually clamp the workpiece. However, there are errors in manually correcting the accuracy of the gear ring, which may affect the grinding accuracy of the tooth surface of the internal gear ring subsequently.

[0003] The Chinese patent document with the publication number CN111889821A proposes an automatic centering and pressing device for internal gear ring processing. By driving the outer ring and the inclined plane adjustment block fixedly connected to the outer ring to rotate through a thin hydraulic cylinder, and pushing the three equally distributed rollers to move radially along the workpiece through the circumferential rotation of the inclined plane adjustment block, the internal gear ring automatically adjusts its position until the center of the gear ring coincides with the center of the workbench to solve the above technical problems. However, there will still be a situation where the outside of the internal gear ring is surrounded after being automatically centered and installed. During the subsequent fine grinding process of the tooth surface, debris will splash or accumulate in the middle processing area of the device, affecting the processing accuracy.

[0004] Therefore, the present invention proposes a processing device and a processing technology for an internal gear ring of a wind power gearbox, which solve the problem that in the prior art, when relying on the device to push the internal gear ring to automatically move for centering and installation, the outside of the internal gear ring will be surrounded, and during the subsequent fine grinding process of the tooth surface, debris will splash or accumulate in the middle processing area of the device, affecting the processing accuracy. By improving the design of the internal gear ring mounting seat and integrating the internal gear ring centering structure and the automatic chip removal structure, after the internal gear ring is automatically centered and installed, the debris generated during subsequent gear grinding can be automatically collected, avoiding the subsequent accumulation or splashing of debris and affecting the processing accuracy.

[0015] The present invention also proposes a processing technology for the inner gear ring of a wind power gearbox, comprising the following steps: step 1, placing the inner gear ring; first, the inner gear ring centering mounting frame is moved in a centering manner under the cooperation of the movable guide rail and the limiting position of the mounting shell, and the position is roughly adjusted according to the diameter of the inner gear ring, so that the inner gear ring can be placed on the mounting platform and is located on the inner side of the centering limiting seat, and after the inner gear ring is placed, the position of the inner gear ring centering mounting frame is continuously adjusted, and at this time, the inner gear ring centering mounting frame automatically fine-tunes the position of the inner gear ring until the centering limiting seat contacts the outer wall of the inner gear ring, and at this time, the center of the inner gear ring coincides with the center of the processing table, and the coaxiality of the inner gear ring and the processing table is corrected to be unified;

[0016] Step 2, determine the first processing area; the telescopic rod pushes the chip cover to move so that it is close to the tooth surface of the inner gear ring, and the floating claw inside the fixed frame moves toward the inner gear ring when the chip cover moves toward the inner gear ring, and performs adaptive floating steering according to the tooth surface of the gear ring in the area close to the chip cover, and correctly engages with the tooth surface, and the tooth surface inside the chip cover is determined as the first processing area;

[0017] Step 3: Conduct gear grinding. The parallel moving component adjusts the distance between the longitudinal moving component and the fine grinding base of the internal gear ring according to the diameter of the internal gear ring to be processed. The longitudinal moving component makes the fine grinding component move vertically downward through the fine grinding mounting frame. A small driving motor and a mounting shaft seat are installed at the bottom of the fine grinding component. A gear grinding roll is fixedly installed on the mounting shaft seat through bolts. When the gear grinding roll at the bottom of the fine grinding component descends above the internal gear ring, the first side protective cover and the second side protective cover are at the lowest positions of the limit sliding grooves on the sides of the fine grinding component. At this time, the sealing guide ring below the first side protective cover will be stuck into the inside of the chip discharging cover. The first side protective cover and the chip discharging cover form a complete dust suction cover, which is located outside the gear grinding roll and is in a semi-surrounding shape. The second side protective cover will be above the surface of the internal gear ring. The right-angle groove of the guide groove plate presses on the internal gear ring. Then the fine grinding component continues to move downward. The small driving motor drives the mounting shaft seat and the gear grinding roll to rotate, and performs high-precision grinding on the tooth surface of the internal gear ring. The industrial dust suction fan works to suck the chips splashed on the side of the gear grinding roll through the dust suction pipe and the fan-shaped dust suction branch pipe for the adsorption cover composed of the chip discharging cover and the first side protective cover. The fan-shaped dust suction tank body is aspirated through the dust suction pipe and the corrugated branch pipe, so that the chips ground below during the gear grinding are sucked out through the chip discharging through groove;

[0018] Step 4: Replace the processing area. After the local tooth surface gear grinding is completed, the fine grinding mounting frame is lifted to the highest point in cooperation with the longitudinal moving component, so that the first side protective cover is separated from the chip discharging cover, and the second side protective cover cancels the pressing effect on the internal gear ring. At this time, the internal gear ring is driven by the rotating frame, the telescopic rod, and the chip discharging cover to rotate clockwise by a certain angle, and the processed part of the tooth surface of the internal gear ring is rotated out. Then the telescopic rod resets to drive the chip discharging cover to retreat and cancel the clamping of the floating claw on the internal gear ring. Then the rotating frame rotates counterclockwise by the same angle to reset the chip discharging cover. Finally, the telescopic rod will push the chip discharging cover to move again so that the floating claw inside the fixed frame is re-clamped with the tooth surface. The fine grinding component repeats the downward movement in cooperation with the fine grinding mounting frame and the longitudinal moving component. The sealing guide ring below the first side protective cover is stuck into the inside of the chip discharging cover again. The right-angle groove of the guide groove plate presses on the internal gear ring again. Finally, the fine grinding component moves downward again so that the gear grinding roll continues to perform gear grinding on the internal gear ring. The industrial dust suction fan works again to suck the chips generated by the gear grinding through the dust suction pipe, and repeats replacing the processing area until the overall tooth surface grinding of the internal gear ring is completed.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] By designing the cooperation of the centering installation component and the chip removal component of the internal gear ring, when installing the internal gear ring, not only can the height of the internal gear ring be lifted to facilitate the complete grinding of the tooth surface of the internal gear ring, but also the position of the internal gear ring can be automatically adjusted to keep its coaxiality with the processing platform unified. The chip removal cover not only engages with the inner tooth surface of the inner ring under the cooperation of the rotating frame and the telescopic rod to increase the stability of the grinding process of the internal gear ring, but also drives the internal gear ring to rotate to change the grinding area. At the same time, it can also engage with the side protective cover one for auxiliary positioning, block the chips generated in the grinding area of the internal gear ring, and can also suck out the chips through the cooperation of the suction pipe and the industrial suction fan. In addition to shielding the outside of the processing area, the side protective cover two makes the chip adsorption area more concentrated, making it easier to suck out the chips and avoid chip splashing. It can also press the internal gear ring through the guide groove plate to increase the stability of the internal gear ring processing. Description of the Drawings

[0039] In order to clearly and completely describe the objectives, technical solutions of the present invention and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] Please refer to Figures 1 to 16, the present invention provides a technical solution: a processing device for the internal gear ring of a wind power gearbox, including an internal gear ring precision grinding processing base 1. On one side of the internal gear ring precision grinding processing base 1, there is a parallel movement component 2. Above the parallel movement component 2, there is a longitudinal movement component 3. The parallel movement component 2 consists of a bottom slide, a sliding platform installed above the slide, and a bottom drive component installed at the rear end of the slide. The longitudinal movement component 3 mainly consists of a longitudinal slide installed on the sliding platform, a longitudinal sliding platform installed inside the longitudinal slide, and a longitudinal drive component installed above the longitudinal slide. The specific working method is that the bottom drive component can drive the sliding platform to slide on the bottom slide, causing the longitudinal slide installed on the sliding platform to move closer to or farther away from the internal gear ring precision grinding processing base 1, facilitating the adjustment of the distance from the internal gear ring precision grinding processing base 1 according to the diameter of the internal gear ring to be processed. The longitudinal drive component can drive the longitudinal sliding platform to move vertically up and down along the longitudinal slide. The precision grinding installation frame 4 mainly serves to install the precision grinding component 41 on the longitudinal sliding platform, enabling the precision grinding component 41 to move vertically up and down along with the longitudinal slide. At the bottom of the precision grinding component 41, there are a small drive motor and an installation shaft seat, and a grinding gear roller is fixedly installed on the installation shaft seat through bolts. During the vertical up and down movement of the precision grinding component 41, the small drive motor drives the installation shaft seat and the grinding gear roller to rotate, performing high-precision grinding processing on the tooth surface of the internal gear ring to ensure accurate tooth shape and high surface finish, thereby reducing frictional losses and noise during operation. The grinding gear roller can be disassembled and replaced according to the model of the internal gear ring to be processed. In the middle of the upper surface of the internal gear ring precision grinding processing base 1, there is a central installation frame 11 fixedly installed. In the middle of the central installation frame 11, there is a chip removal component 6. The chip removal component 6 includes a rotating frame 61, a telescopic rod 62, a chip removal cover 63, and a dust suction pipe 64. The rotating frame 61 is rotatably installed in the middle of the central installation frame 11. Below the outer surface of the rotating frame 61, there is an inclined gear disk fixedly installed. On the inner side wall of the central installation frame 11, there is a rotating rod rotatably installed. On the outer side wall of the central installation frame 11, there is a drive motor one fixedly installed to drive the rotating rod to rotate. At one end of the rotating rod, there is a bevel gear fixedly installed to drive the inclined gear disk to rotate. The telescopic rod 62 is fixedly installed on the upper surface of the rotating frame 61. The output end of the telescopic rod 62 is fixedly connected to the side surface of the chip removal cover 63. The inner side wall of the chip removal cover 63 is evenly provided with through slots. The dust suction pipe 64 is fixedly installed on one side inside the central installation frame 11. The dust suction pipe 64 penetrates the bottom inner wall of the central installation frame 11. At the upper end of the dust suction pipe 64, there is a corrugated branch pipe 642. On one side of the rotating frame 61, there is a fan-shaped groove for the corrugated branch pipe 642 to move. One end of the corrugated branch pipe 642 is fixedly connected to the side surface of the chip removal cover 63. On the side surface of the chip removal cover 63, there is a through hole adapted to the corrugated branch pipe 642. On both side walls of the chip removal cover 63, there are fixing frames 631 symmetrically fixedly installed. Inside one end of the fixing frame 631, there is a floating claw 6311 rotatably installed.Elastic limit gaskets are respectively fixedly installed between the two side surfaces of the floating claw 6311 and the inner side wall of the fixed frame 631; in this embodiment, the central mounting frame 11 mainly functions to mount the rotating frame 61. The rotating rod on the side wall of the central mounting frame 11 is driven to rotate by the driving motor 1 on the outer side wall of the central mounting frame 11, so that the bevel gear mounted on the rotating rod drives the helical gear disk mounted on the lower surface of the rotating frame 61 to rotate, and then the rotating frame 61 rotates. The telescopic rod 62 mainly functions to push the chip removal cover 63 to move, so that it approaches the tooth surface of the internal gear ring. The floating claw 6311 inside the fixed frame 631 will perform adaptive floating steering according to the tooth surface of the internal gear ring in the approaching area when the chip removal cover 63 moves towards the internal gear ring, and maintain correct engagement with the tooth surface. The specific working mode of the chip removal cover 63 is as follows: First, the telescopic rod 62 will push the chip removal cover 63 to move so that the floating claw 6311 inside the fixed frame 631 engages with the tooth surface. Then, the rotating frame 61 rotates clockwise driven by the driving motor 2. The specific rotation angle needs to be set according to the number of teeth and diameter of the internal gear ring. For example, it is set that the rotating frame 61 rotates 6° clockwise each time driven by the driving motor 2, so as to drive the internal gear ring to rotate 6° clockwise, and rotate out the processed part of the tooth surface of the internal gear ring. Then the telescopic rod 62 resets and drives the chip removal cover 63 to retreat to cancel the engagement of the floating claw 6311 with the internal gear ring. At this time, the rotating frame 61 rotates counterclockwise 6° driven by the driving motor 2 to reset the chip removal cover 63. Finally, the telescopic rod 62 will push the chip removal cover 63 to move again so that the floating claw 6311 inside the fixed frame 631 engages with the tooth surface to re-fix the internal gear ring for subsequent continuous processing. In this way, the entire processing of the internal gear ring requires the rotating frame 61 and the telescopic rod 62 to work 60 times repeatedly. However, in the actual processing process, considering the large size of the internal gear ring in the wind power gearbox, it is necessary to ensure that there is an overlapping part in the processed part of the tooth surface of the internal gear ring each time when setting the rotation angle of the rotating frame 61, so as to avoid the problem of unprocessed tooth surfaces. The dust suction pipe 64 is mainly connected to the chip removal cover 63 through the corrugated branch pipe 642. When the internal gear ring is subjected to gear grinding processing, the dust suction pipe 64 sucks away the chips generated by gear grinding through the fan-shaped dust suction branch pipe 641 through the through groove on the inner side wall of the chip removal cover 63, which can effectively avoid the problem that the chips will splash or accumulate in the middle processing area of the device and affect the processing accuracy.,

[0042] Embodiment 2

[0043] Please refer to Figures 1 to 16, on the basis of the first embodiment, this embodiment further proposes that an industrial dust suction fan 65 is provided on one side of the inner gear ring precision grinding base 1. A suction air pipe 651 is fixedly installed at the suction pipe end of the industrial dust suction fan 65. The suction air pipe 651 penetrates through the lower side wall of the inner gear ring precision grinding base 1. A filter cover net 652 is fixedly installed at the upper end of the suction air pipe 651. The filter cover net 652 is in the shape of a baseball bat. The top of the filter cover net 652 is a smooth hemispherical metal sheet. A debris collection cylinder 66 is arranged outside the filter cover net 652. The lower inner surface of the debris collection cylinder 66 is threadedly connected to the outer surface of the bottom of the filter cover net 652. An upper sealing ring 661 is fixedly installed above the inner surface of the debris collection cylinder 66. A through groove adapted to the dust suction pipe 64 is arranged in the middle of the upper sealing ring 661. A chip discharge sealing plug 662 is snap-fitted and installed below the debris collection cylinder 66. An assembly hole adapted to the chip discharge sealing plug 662 is arranged at the bottom of the filter cover net 652; in this embodiment, the dust suction pipe 64 is connected to the suction air pipe 651 through the debris collection cylinder 66 to form a set of closed pipelines. The industrial dust suction fan 65 mainly sucks dust through the suction air pipe 651, the debris collection cylinder 66 and the dust suction pipe 64. The debris generated during the inner gear ring processing is sucked into the debris collection cylinder 66 by the dust suction pipe 64. The filter cover net 652 can filter and intercept the debris, so that the debris accumulates below the debris collection cylinder 66. The debris can be discharged by pulling out the chip discharge sealing plug 662. The upper sealing ring 661 mainly increases the sealing performance at the socket joint of the debris collection cylinder 66 and the dust suction pipe 64. The debris collection cylinder 66 is designed to be detachably installed outside the filter cover net 652, which is convenient for cleaning the filter cover net 652 after the debris collection cylinder 66 is disassembled. At the same time, the filter cover net 652 is designed with a wide top and a narrow bottom like a baseball bat. After the metal debris falls with the air and lands on the filter cover net 652, it is dispersed to the outside, reducing the blockage effect on the side filter screen of the filter cover net 652.

[0044] Embodiment Three

[0045] Please refer to Figures 1 to 16, on the basis of Embodiment 2, the present embodiment further proposes that a fine grinding mounting frame 4 is provided on one side of the longitudinal movement assembly 3 close to the inner gear ring fine grinding processing base 1. A fine grinding assembly 41 is fixedly installed at one end of the fine grinding mounting frame 4. A first side protective cover 42 is provided on one side of the fine grinding assembly 41 close to the chip removal cover 63. Both the first side protective cover 42 and the chip removal cover 63 are "C"-shaped. Through grooves are evenly formed in the inner side wall of the first side protective cover 42. A sealing guide ring 421 adapted to the chip removal cover 63 is fixedly installed at the bottom of the first side protective cover 42. A second side protective cover 43 is provided on the other side of the fine grinding assembly 41. Guide groove plates 431 are evenly distributed on the inner surface of the second side protective cover 43. Right-angle grooves are formed below the side walls of the guide groove plates 431. Limiting sliding grooves adapted to the first side protective cover 42 and the second side protective cover 43 are respectively provided on both sides of the fine grinding assembly 41. Telescopic spring rods are respectively fixedly installed between the upper surfaces of the first side protective cover 42 and the second side protective cover 43 and the lower surface of the fine grinding mounting frame 4;In this embodiment, the fine grinding assembly 41 mainly functions to install the gear grinding roll. With the cooperation of the longitudinal movement assembly 3, the fine grinding assembly 41 moves vertically up and down. The small drive motor installed at the bottom of the fine grinding assembly 41 drives the installation shaft seat and the gear grinding roll to rotate, performing high-precision grinding on the tooth surface of the internal gear ring. When the gear grinding roll at the bottom of the fine grinding assembly 41 descends above the internal gear ring, due to the action of the telescopic spring rods under the fine grinding mounting frame 4, the side protective cover one 42 and the side protective cover two 43 will be at the lowest position of the limit chute on the side of the fine grinding assembly 41. At this time, the sealing guide ring 421 under the side protective cover one 42 will snap into the inside of the chip removal cover 63, and the side protective cover one 42 and the chip removal cover 63 will form a complete dust suction cover, located outside the gear grinding roll, in a semi-surrounding shape, facilitating the suction and collection of the chips generated during gear grinding. And the side protective cover two 43 will be above the surface of the internal gear ring, and the right-angle groove of the guide groove plate 431 will exert a pressing effect on the internal gear ring, making the gear grinding process more stable. As the fine grinding assembly 41 continues to move downward to grind the teeth of the internal gear ring, the telescopic spring rods will be compressed. At this time, the side protective cover one 42 and the side protective cover two 43 will slide along the limit chute of the fine grinding assembly 41. The side protective cover one 42 will continue to maintain the engagement state with the chip removal cover 63, and the guide groove plate 431 inside the side protective cover two 43 will also continue to maintain the pressing state on the internal gear ring. After the local tooth surface grinding is completed, the fine grinding mounting frame 4 is lifted to the highest point with the cooperation of the longitudinal movement assembly 3, so that the side protective cover one 42 is separated from the chip removal cover 63, and the side protective cover two 43 also cancels the pressing effect on the internal gear ring. At this time, after the internal gear ring is driven by the rotating frame 61, the telescopic rod 62, and the chip removal cover 63 to rotate a certain angle, the rotating frame 61 and the telescopic rod 62 cooperate to reset the chip removal cover 63. The fine grinding assembly 41 repeats the downward movement for gear grinding with the cooperation of the fine grinding mounting frame 4 and the longitudinal movement assembly 3. Therefore, in addition to assisting in fixing the internal gear ring, the chip removal cover 63 also has a positioning and calibration function for the position of the fine grinding assembly 41 by cooperating with the side protective cover two 43, making the position of the gear grinding roll at the bottom of the fine grinding assembly 41 correct, ensuring the accuracy of the gear grinding process for the internal gear ring, and improving the processing accuracy. The side protective cover one 42 not only shields the chips generated during the grinding process of the gear grinding roll, but also engages with the chip removal cover 63 for auxiliary positioning, and can also suck out the chips through the cooperation of the dust suction pipe 64 and the industrial dust suction fan 65. In addition to pressing the internal gear ring through the fixing frame 631, the chip removal cover 63 can also shield and protect the outside of the processing area, making the chip adsorption area more concentrated and making it easier to suck out the chips to avoid chip splashing.;

[0046] Embodiment Four

[0047] Please refer to Figures 1 to 16, on the basis of Embodiment 3, the present embodiment further proposes that an internal gear ring centering and mounting assembly 5 is provided on the outer side above the internal gear ring precision grinding base 1. The internal gear ring centering and mounting assembly 5 includes a mounting housing 51 and an internal gear ring centering and mounting frame 54. The mounting housing 51 is fixedly installed on the outer side above the internal gear ring precision grinding base 1. Inside the mounting housing 51 near the longitudinal movement assembly 3, a sector-shaped dust suction trough 55 is fixedly installed. A chip discharge through groove 551 is provided above the sector-shaped dust suction trough 55. A sector-shaped dust suction branch pipe 641 is fixedly installed on the side wall of the dust suction pipe 64. One end of the sector-shaped dust suction branch pipe 641 is fixedly connected to the side wall of the sector-shaped dust suction trough 55. A processing table 52 is fixedly installed above the mounting housing 51 by bolts. The processing table 52 is horseshoe-shaped and is flush with the surfaces of the mounting housing 51, the rotating frame 61, and the sector-shaped dust suction trough 55. An activity groove adapted to the rotating frame 61 is provided in the middle of the processing table 52. The chip discharge cover 63 is arranged on the upper surface of the sector-shaped dust suction trough 55. In this embodiment, the mounting housing 51 and the processing table 52 cooperate to form a processing platform. The processing table 52 is convenient for disassembly and maintenance. The sector-shaped dust suction trough 55 is connected to the dust suction pipe 64 through the sector-shaped dust suction branch pipe 641. When the internal gear ring is subjected to gear grinding, with the cooperation of the industrial dust suction fan 65, the dust suction pipe 64 works to suck the chips splashing from the side of the gear grinding roller through the suction hood formed by the chip discharge cover 63 and the side protection cover 42 through the sector-shaped dust suction branch pipe 641. At the same time, the dust suction pipe 64 sucks the sector-shaped dust suction trough 55 through the corrugated branch pipe 642, so that the chips ground below the gear grinding are sucked out through the chip discharge through groove 551, increasing the cleaning strength of the chips and avoiding the influence of chip accumulation on subsequent processing;There are three sets of centering mounting frames 54 for the internal gear ring. The lower surfaces of the three sets of centering mounting frames 54 for the internal gear ring are all in contact with the upper surfaces of the mounting housing 51 and the processing table 52. The included angle between the two sets of centering mounting frames 54 close to the longitudinal moving component 3 is 60°. The other set of centering mounting frames 54 for the internal gear ring is arranged on the axis coinciding with the longitudinal moving component 3. A moving guide rail 53 adapted to the position of the centering mounting frame 54 for the internal gear ring is fixedly installed on the inner surface of the mounting housing 51. A threaded rod is rotatably installed inside the moving guide rail 53. A T-shaped plate slidably connected to the centering mounting frame 54 for the internal gear ring is arranged at the bottom of the centering mounting frame 54 for the internal gear ring. The bottom side wall of the T-shaped plate is threadedly connected to the outer surface of the threaded rod. A chute adapted to the centering mounting frame 54 for the internal gear ring is provided on the side wall of the mounting housing 51. A second driving motor for driving the threaded rod to rotate is fixedly installed on the outer surface of the mounting housing 51. The three second driving motors need to work synchronously. Below the internal gear ring fine grinding processing base 1, there is an equipment control box for controlling the parallel moving component 2, the longitudinal moving component 3, the telescopic rod 62, the industrial dust suction fan 65, and all driving motors. In this embodiment, the centering mounting frame 54 for the internal gear ring mainly serves to carry the internal gear ring, so that after the internal gear ring is placed, there is a certain processing height from the processing table 52, which is convenient for the grinding rollers at the bottom of the fine grinding component 41 to generate grinding effects on the entire tooth surface of the internal gear ring from top to bottom, avoiding the problem of incomplete processing of the lower part of the tooth surface of the internal gear ring. Under the control of the equipment control box, the three second driving motors drive the threaded rod inside the moving guide rail 53 to rotate, so that the centering mounting frame 54 for the internal gear ring performs centering movement under the limit cooperation of the moving guide rail 53 and the mounting housing 51, moves according to the diameter of the internal gear ring, and roughly adjusts the position, so that the internal gear ring can be placed on the mounting platform 541 and is inside the centering limit seat 542. Then, the position of the centering mounting frame 54 for the internal gear ring will be continuously adjusted. At this time, the centering mounting frame 54 for the internal gear ring automatically makes a fine adjustment to the position of the internal gear ring until the centering limit seat 542 abuts against the outer wall of the internal gear ring. At this time, the center of the internal gear ring coincides with the center of the processing table 52, achieving the purpose of automatically correcting the coaxiality unity of the internal gear ring and the processing table 52, and making the subsequent gear grinding processing accuracy of the internal gear ring unified;One end of the centering mounting frame 54 of the internal gear ring close to the rotating frame 61 is fixedly installed with a mounting platform 541. Above the centering mounting frame 54 of the internal gear ring, a centering limit seat 542 is fixedly installed. Inside the mounting platform 541, an inclined roller mounting shaft 5412 is rotatably installed obliquely. On the outer surface of the inclined roller mounting shaft 5412, an inclined roller 5411 is fixedly installed. Above the mounting platform 541, a limit cover plate adapted to the inclined roller 5411 is detachably installed. On one side of the inclined roller mounting shaft 5412, a rotating limit tooth 5414 is movably installed. On one side of the rotating limit tooth 5414, a limit dial is provided. The limit dial is fixedly installed on the side wall of the inclined roller mounting shaft 5412. On the inner side wall of the mounting platform 541, a locking limit ring 5413 adapted to the inclined roller mounting shaft 5412 is fixedly installed. Inside the locking limit ring 5413, a limit tooth groove adapted to the rotating limit tooth 5414 is provided. In this embodiment, in addition to automatically adjusting the coaxiality between the internal gear ring and the processing table 52, the centering mounting frame 54 of the internal gear ring also has the function of lifting the internal gear ring above the processing table 52, so that the tooth surface of the internal gear ring is convenient for being completely ground by the grinding roller. The mounting platform 541 mainly plays the role of carrying the internal gear ring. The inclined rollers 5411 are distributed obliquely, which is convenient for the chip removal cover 63 to drive the internal gear ring to rotate and replace the grinding area under the cooperation of the rotating frame 61 and the telescopic rod 62, reducing the friction force. At the same time, through the cooperation of the inclined roller mounting shaft 5412 and the locking limit ring 5413 by the rotating limit tooth 5414, using the ratchet principle, the inclined roller 5411 is limited to rotate only in one direction, and the internal gear ring is driven to rotate in the limited direction in cooperation with the chip removal cover 63, further restricting the rotation direction of the internal gear ring, avoiding the error of the rotation direction of the internal gear ring, and increasing the stability of the process of the internal gear ring rotating and replacing the grinding area. The centering limit seat 542 limits the internal gear ring to keep it coaxial with the processing table 52 all the time, and the balls 5421 reduce the friction force when the internal gear ring rotates.;

[0048] Embodiment Five

[0049] Please refer to Figure 17 , on the basis of Embodiment Four, this embodiment also proposes a processing technology for the internal gear ring of a wind power gearbox, including the following steps:

[0050] Step 1, place the internal gear ring; First, under the control of the equipment control box, the three groups of drive motors two drive the rotation of the threaded rod inside the moving guide rail 53, so that the internal gear ring centering mounting frame 54 makes a centering movement under the limit cooperation of the moving guide rail 53 and the mounting housing 51, and the position is roughly adjusted according to the diameter of the internal gear ring, so that the internal gear ring can be placed on the mounting platform 541 and inside the centering limit seat 542. After the internal gear ring is placed, continue to adjust the position of the internal gear ring centering mounting frame 54. At this time, the internal gear ring centering mounting frame 54 automatically makes a fine adjustment to the position of the internal gear ring until the centering limit seat 542 abuts against the outer wall of the internal gear ring. At this time, the center of the internal gear ring coincides with the center of the processing table 52, and the coaxiality of the internal gear ring and the processing table 52 is unified.

[0051] Step 2, determine the first machining area; The telescopic rod 62 pushes the chip removal cover 63 to move, making it close to the tooth surface of the internal gear ring. The floating claws 6311 inside the fixing frame 631 will make an adaptive floating turn according to the tooth surface of the internal gear ring in the approaching area when the chip removal cover 63 moves towards the internal gear ring, and keep correct engagement with the tooth surface. At this time, the tooth surface inside the chip removal cover 63 is determined as the first machining area;

[0052] Step 3: Conduct gear grinding. The bottom drive assembly can drive the sliding platform to slide on the bottom slide, causing the longitudinal slide installed on the sliding platform to move, facilitating the adjustment of the distance from the fine grinding base 1 of the internal gear ring to be processed according to the diameter of the internal gear ring. The longitudinal drive assembly can drive the longitudinal sliding platform to move vertically downward along the longitudinal slide. Through the fine grinding mounting frame 4, the fine grinding assembly 41 moves vertically downward along with the longitudinal slide. A small drive motor and a mounting shaft seat are installed at the bottom of the fine grinding assembly 41, and a gear grinding roll is fixedly installed on the mounting shaft seat through bolts. When the gear grinding roll at the bottom of the fine grinding assembly 41 descends above the internal gear ring, under the action of the telescopic spring rod below the fine grinding mounting frame 4, the first side protective cover 42 and the second side protective cover 43 will be at the lowest position of the limit chute on the side of the fine grinding assembly 41. At this time, the sealing guide ring 421 below the first side protective cover 42 will be stuck into the inside of the chip removal cover 63. The first side protective cover 42 and the chip removal cover 63 will form a complete dust suction cover, located outside the gear grinding roll, in a semi-surrounding shape, facilitating the suction and collection of the debris generated by gear grinding. And the second side protective cover 43 will be above the surface of the internal gear ring, and the right-angle groove of the guide groove plate 431 will exert a pressing force on the internal gear ring, making the gear grinding process more stable. As the fine grinding assembly 41 continues to move downward, the small drive motor drives the mounting shaft seat and the gear grinding roll to rotate, performing high-precision grinding on the tooth surface of the internal gear ring, enabling the gear grinding roll to grind the internal gear ring. At this time, the first side protective cover 42 and the second side protective cover 43 will slide along the limit chute of the fine grinding assembly 41. The first side protective cover 42 continues to maintain the engagement state with the chip removal cover 63, and the guide groove plate 431 inside the second side protective cover 43 also continues to maintain the pressing state on the internal gear ring. The industrial dust suction fan 65 operates to suck out the debris splashed on the side of the gear grinding roll through the dust suction pipe 64 and the fan-shaped dust suction branch pipe 641 for the adsorption cover formed by the chip removal cover 63 and the first side protective cover 42. At the same time, the dust suction pipe 64 and the corrugated branch pipe 642 suck the fan-shaped dust suction tank body 55, so that the debris ground below during gear grinding is sucked out through the chip removal through groove 551;

[0053] Step 4: Replace the machining area. After the local tooth surface grinding of the inner gear ring is completed, the fine grinding mounting frame 4 is lifted to the highest point with the cooperation of the longitudinal movement assembly 3, so that the first side protective cover 42 is separated from the chip removal cover 63, and the second side protective cover 43 also cancels the pressing effect on the inner gear ring. At this time, the inner gear ring is driven by the rotation of the rotating frame 61, the telescopic rod 62, and the chip removal cover 63 to rotate clockwise by a certain angle, rotating out the machined part of the tooth surface of the inner gear ring. Then, the telescopic rod 62 resets and drives the chip removal cover 63 to retract, canceling the engagement of the floating claw 6311 on the inner gear ring. At this time, the drive motor two drives the rotating frame 61 to rotate counterclockwise by the same angle to reset the chip removal cover 63. Finally, the telescopic rod 62 will push the chip removal cover 63 to move again so that the floating claw 6311 inside the fixed frame 631 engages with the tooth surface to re-fix the inner gear ring. The fine grinding assembly 41 repeats the downward movement with the cooperation of the fine grinding mounting frame 4 and the longitudinal movement assembly 3. The sealing guide ring 421 under the first side protective cover 42 will be inserted into the inside of the chip removal cover 63 again, and the right-angle groove of the guide groove plate 431 will exert a pressing effect on the inner gear ring again. Then, the fine grinding assembly 41 moves downward again so that the grinding roll continues to grind the inner gear ring. The industrial dust suction fan 65 works again to suck the chips generated by grinding through the dust suction pipe 64. Repeat replacing the machining area until the overall tooth surface grinding of the inner gear ring is completed.
