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 making creative efforts are within the scope of protection of the present invention.

The cutting and processing device for a large wind power high-speed gearbox body also includes a material table assembly 5 and a transmission assembly 6. The material table assembly 5 is arranged inside the outer shell 1 and extends to the outside of the outer shell 1; there are two transmission assemblies 6, which are respectively located on the front and back of the outer shell 1, and are both installed between the material table assembly 5 and the closed door 7; wherein, the material table assembly 5 is used to transport the gearbox to the interior of the outer shell 1, and the closed door 7 is synchronously closed by the transmission assembly 6.

[0032] In the implementation process, it is worth noting that the inside of the shell 1 is a cavity for installing the multi-axis system 3 and the cutting knife 2, and the necessary light supplementing lamp, and the shell 1 can be connected to a purification system for processing the smoke generated by laser cutting, and the specific model of the cutting knife 2 is not limited, as long as it meets the use requirements, wherein the multi-axis system 3 should include an X, Y, Z three-axis linkage control system, which realizes precise positioning through servo motor driving, so as to realize multi-position cutting of the cutting knife 2, which can effectively cut off the casting riser and flash on the surface of the gear box.

[0033] In an implementable manner, the material table assembly 5 includes a placement plate 51, a bottom plate 52, a frame 53, a power unit 54, and an adapter 55, the placement plate 51 is arranged on one side of the shell 1; the bottom plate 52 is slidingly connected to the bottom of the placement plate 51 and extends to the inside of the shell 1; the frame 53 is provided with two, respectively fixed to the front and rear of the bottom plate 52 and extends to the inner wall of the shell 1 and is fixed to the inner wall of the shell 1; the power unit 54 is installed between the frame 53 and the bottom plate 52; the adapter 55 is detachably connected to the top of the placement plate 51; wherein the adapter 55 cooperates with the placement plate 51 to place the gear box to be processed, and the placement plate 51 is driven to move along the surface of the bottom plate 52 by the power unit 54.

[0034] In the implementation process, it is worth noting that the bottom plate 52 cooperates with the frame 53 to bear the weight, and the top of the placement plate 51 can better support the gear box by installing the adapter 55, because the gear box is heavy and is cut by laser, so the gear box is stable after cooperating with the adapter 55, without the need for additional clamping and fixing, and because there is no obstruction outside the gear box, it is beneficial to cut the flash and riser position, the adapter 55 is provided in multiple specifications and models, so that appropriate adapters 55 are selected for different specifications and production batches of gear boxes, which is beneficial to effectively support the gear box, the bottom of the frame 53 is provided with a foot for supporting and leveling, the power unit 54 can send the placement plate 51 with the gear box into the inside of the shell 1, and after cutting is completed, the placement plate 51 with the gear box is sent out of the shell 1, and when the gear box is placed on the placement plate 51 or taken off from above the placement plate 51, a mechanical hand or a lifting tool can be used for cooperation.

[0035] Further, the power unit 54 includes a transmission belt 541 and a support roller 542, the transmission belt 541 is respectively fixed at both ends of the placement plate 51; the support roller 542 is provided with two, respectively rotatingly connected to the top of the bottom plate 52, and the outer wall is fitted to the inner wall of the transmission belt 541; wherein the support roller 542 drives the placement plate 51 to move through forward and reverse rotation under the transmission of the transmission belt 541.

[0036] In the embodiment, it is worth pointing out that the supporting roller 542 is used for guiding the transmission belt 541, and the placement plate 51 can also be driven in the form of a chain wheel and a chain, so that the slippage can be avoided, the precision is higher, and the supporting roller 542 should have a power device, such as a servo motor, which can be connected to the control panel 4 and uniformly controlled by the control panel 4.

[0037] In an embodiment, the bottom of the adapter 55 is fixedly connected with a plug rod 551, and the plug rod 551 is inserted into the inside of the placement plate 51 through a plug hole 552 formed in the top of the placement plate 51.

[0038] In the embodiment, it is worth pointing out that the matching mode of the plug rod 551 and the plug hole 552 is simple, and the fixing mode of the adapter 55 is effective and convenient for replacing the adapter 55 because of the gravity of the gear box downward.

[0039] It can be understood that the plug hole 552 is a through hole, which is designed to facilitate the cleaning of cutting debris into the inside, and part of the debris can fall through the plug hole 552 to the bottom of the placement plate 51. Therefore, the position of the sliding clamping between the placement plate 51 and the bottom plate 52 can be provided with a soft protective cover, or a shovel can be provided at the bottom of the placement plate 51, which can shovel the metal debris at the sliding clamping position with the movement of the placement plate 51, to ensure the smooth sliding clamping between the two.

[0040] In an embodiment, a reserved groove 11 is formed in the surface of the shell 1, the transmission assembly 6 comprises a transmission tooth plate 61, a first gear 62, a transmission rod 63, a reverse unit 64, a second gear 65 and a tooth 66, the transmission tooth plate 61 is fixedly connected to the surface of the placement plate 51 and extends into the inside of the reserved groove 11; the first gear 62 is arranged on the surface of the shell 1 and located on the side away from the shell 1 of the transmission tooth plate 61; the transmission rod 63 is fixedly connected to the inner wall of the first gear 62 and rotatably connected to the surface of the shell 1 through a bearing at the bottom; the reverse unit 64 is installed at the end of the transmission rod 63 away from the first gear 62; the second gear 65 is drivingly connected with the transmission rod 63 through the reverse unit 64; the tooth 66 is formed in the surface of the closed door 7 and meshingly connected to the side of the second gear 65 close to the shell 1; wherein the transmission tooth plate 61 is driven by the placement plate 51 to approach the shell 1, and the power is transmitted to the transmission rod 63 by cooperating with the tooth on the surface and the first gear 62, the transmission rod 63 drives the second gear 65 to rotate under the action of the reverse unit 64, and then the closed door 7 is closed.

[0041] In the embodiment, it is worth pointing out that the purpose of the reserved groove 11 is to support the end of the transmission tooth plate 61 to avoid sagging and bending under the action of gravity. The transmission tooth plate 61 is provided with only part of the teeth on one side of the placing plate 51. Therefore, when the placing plate 51 is initially moved into the shell 1, the first gear 62 does not mesh with the transmission tooth plate 61, and thus the closing door 7 does not move downward. When the placing plate 51 and the top gear box have completely or are about to completely enter the shell 1, the teeth of the transmission tooth plate 61 mesh with the first gear 62. Therefore, the closing door 7 does not interfere with the gear box or the placing plate 51 when the closing door 7 is closed, and no external power structure is required to close the closing door 7. The closing door 7 can be automatically opened by the transmission assembly 6 when the placing plate 51 and the gear box move out of the shell 1.

[0042] In an embodiment, the reverse unit 64 comprises a worm 641, a worm wheel 642 and a connecting shaft 643. The worm 641 is fixedly connected to the outer wall of the transmission rod 63. The worm wheel 642 is engaged with the back of the worm 641. The connecting shaft 643 is fixedly connected to the inner wall of the worm wheel 642 and rotatably connected to the outer wall of the shell 1 through a bearing and fixedly connected to one side of the second gear 65. The closing door 7 is locked by the cooperation of the worm 641 and the worm wheel 642.

[0043] In the embodiment, it is worth pointing out that the purpose of the worm 641 and the worm wheel 642 is to prevent the closing door 7 from falling due to gravity when the transmission tooth plate 61 and the first gear 62 lose engagement, i.e., the closing door 7 is located above and the shell 1 is opened. Since the worm 641 and the worm wheel 642 have a self-locking effect, the transmission ratio of the first gear 62 and the second gear 65 should be reasonably designed to achieve complete opening or closing of the closing door 7 when the placing plate 51 moves a small distance. The specific transmission ratio of the first gear 62 and the second gear 65 can be designed according to the actual size of the closing door 7 and the required lifting range.

[0044] In an embodiment, the side of the transmission rod 63 away from the shell 1 is provided with a cover plate 8. The side of the cover plate 8 close to the shell 1 is provided with a clamping rod 81 clamped in a reserved clamping groove on the surface of the shell 1.

[0045] In the embodiment, it is worth pointing out that the cover plate 8 can protect the first gear 62, the second gear 65 and the transmission rod 63, and an opening is reserved to allow the transmission tooth plate 61 to pass through. One side is clamped to the shell 1 by the clamping rod 81, and the other side can be reinforced by screws.

[0046] In an implementable manner, the multi-axis system 3 is installed with a visual detection frame 31 near one side of the placement plate 51, and the visual detection frame 31 is electrically connected to the control panel 4.

[0047] In an implementable manner, a sliding groove 71 that is slidably connected to the inner wall of the shell 1 is opened on the surface of the closing door 7.

[0048] In the specific implementation process, it is particularly worth pointing out that the sliding groove 71 is arranged on the surface of the closing door 7, and the purpose is to improve the stability of the closing door 7 during lifting, avoid tilting or deflection, and a proper amount of lubricating grease can be injected into the inside of the sliding groove 71 to reduce friction.

[0049] Working principle:

[0050] According to the shape and size of the gear box, select the corresponding type of adapter 55, insert the bottom plug rod 551 into the insertion hole 552 at the top of the placement plate 51, complete the quick assembly of the adapter and the placement plate, place the gear box on the top of the adapter 55 by using hoisting equipment, the supporting structure of the adapter is matched with the contour of the gear box, without additional clamps, start the control panel 4, the supporting roller 542 in the power unit 54 is driven by the servo motor to rotate forward, and the placement plate 51 is driven to slide along the surface of the bottom plate 52 into the shell 1 by the transmission belt 541;

[0051] When the placement plate 51 drives the gear box to approach the inside of the shell 1, the transmission gear plate 61 fixed on the surface of the placement plate enters the reserved groove 11, the teeth of the transmission gear plate 61 are engaged with the first gear 62, the first gear 62 drives the transmission rod 63 to rotate, the worm 641 in the reverse unit 64 drives the worm gear 642 to rotate, and then the connecting shaft 643 drives the second gear 65 to rotate, the second gear 65 is engaged with the teeth 66 on the surface of the closing door 7, and the closing door is driven to slide along the sliding groove 71 on the inner wall of the shell 1, until the shell 1 is completely closed, and the self-locking property of the worm 641 and the worm gear 642 ensures that the closing door is locked to prevent accidental opening during cutting;

[0052] The multi-axis system 3 drives the visual detection frame 31 to scan the contour of the gear box, transmits the detection data to the control panel 4, and automatically generates a cutting path (or directly executes through preset coordinates); the multi-axis system 3 (X, Y, Z three-axis linkage) drives the cutting knife 2 to move according to the planned path, and accurately cuts off the riser, flash and other parts on the surface of the gear box, and the purification system (optional) in the shell 1 synchronously processes the generated smoke during the cutting process;

[0053] After cutting is completed, the support roller 542 reverses rotation, the placement plate 51 drives the gear box to move out of the shell 1, the transmission gear plate 61 is engaged with the first gear 62 again, the second gear 65 is reversely driven through the transmission assembly 6, the closing door 7 is lifted along the sliding groove 71 to open, the self-locking characteristic of the worm 641 and the worm wheel 642 ensures that the closing door remains in an open state to avoid interference with the withdrawn placement plate 51, after the placement plate 51 completely exits the shell 1, the gear box is taken down by using hoisting equipment, and the machining process is completed.

[0054] The linear motion of the material table assembly 5 is converted into the lifting motion of the closing door 7 through the transmission assembly 6, the “conveying-protection” linkage is realized, and the closing door does not need to be manually operated; the adapter 55 and the insertion assembly of the placement plate 51 cooperate with the gear box self-weight to form stable support, clamping time is avoided, and meanwhile, it is ensured that the gear box is not shielded during cutting, and all-around machining is facilitated; the mechanical self-locking characteristic of the reverse unit 64 locks the position after the closing door is closed, prevents the closing door from being opened due to cutting vibration or external force, and guarantees work safety.
