Description

Technical Field

[0001] This invention relates to the field of CNC vertical lathe technology, and in particular to a large-scale wind turbine main shaft casting processing equipment. Background Technology

[0002] Castings are key basic components in fields such as machinery manufacturing, automotive industry, and heavy equipment. Castings are widely used in the main shaft structure of some large wind power equipment. These parts are usually complex in shape and need to have high structural strength and wear resistance, which well meets the usage requirements of large wind power equipment and are now widely used.

[0003] Currently, turning castings to achieve predetermined dimensional accuracy and surface finish is a common process in the industry. Existing machining methods typically include the following steps: clamping and positioning, rough turning, semi-finish turning, and finish turning. In the rough turning stage, the operator or CNC system usually uses a large depth of cut and feed rate to quickly remove most of the machining allowance. In the finish turning stage, smaller cutting parameters are used to ensure machining quality. All of the above processes require the use of lathe equipment.

[0004] For large wind turbine main shaft castings, due to their large weight and numerous machining steps, it is often necessary to repeatedly lift and move the castings between multiple different turning machines to perform cutting processes on different parts. However, this affects the machining efficiency of the castings, so it is necessary to improve the existing technology.

[0050] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0051] In the description of this invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present simultaneously. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be an intermediate component present simultaneously.

[0052] Furthermore, terms such as “long,” “short,” “inner,” and “outer” indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0053] The following is in conjunction with the appendix Figure 1-7 The technical solution of the present invention will be further illustrated through specific embodiments.

[0054] Please refer to Figure 1 This invention provides a large wind turbine main shaft casting processing equipment, including a gantry frame 1, a turntable mechanism 2, an end face cutting mechanism 3, and a peripheral cutting mechanism 4.

[0055] The gantry frame 1 includes two vertically arranged columns and a crossbeam fixed to the top of the two columns, thus achieving a stable gantry frame 1 structure. The gantry frame 1 is mainly used to provide installation positions for the end face cutting mechanism 3 and the peripheral cutting mechanism 4, so that each mechanism can be stably supported. It is understood that the specific structure of the gantry frame 1 can be adjusted according to actual needs, and no specific restrictions are made here.

[0056] The turntable mechanism 2 is used to vertically place the casting and drive it to rotate horizontally. Specifically, the turntable mechanism 2 typically includes a base, a rotating platform, a drive motor, and clamps. The rotating platform is rotatably mounted on the base, and the drive motor is connected to the rotating platform and used to drive it to rotate horizontally. At this time, the casting can be suspended vertically on the rotating platform, and the clamps are used to hold and position the casting around its circumference, so that the casting is fixedly installed on the turntable mechanism 2. When the drive motor is started, the casting can be driven to rotate synchronously under the rotation of the rotating platform.

[0057] Based on this, the end face cutting mechanism 3 is movably mounted on the gantry frame 1 and located above the turntable mechanism 2. The end face cutting mechanism 3 is used to perform turning machining on the top of the casting.

[0058] Specifically, the end face cutting mechanism 3 is set on the crossbeam of the gantry 1. At this time, the end face cutting mechanism 3 is located above the casting. The end face cutting mechanism 3 has the ability to move up and down and move laterally. On the one hand, the lateral movement can make the end face cutting mechanism 3 move closer or further away from the casting. On the other hand, the up and down movement can change the feed amount of the turning action. At this time, by adjusting the path of the end face cutting mechanism 3, the top end face of the casting can be turned from top to bottom.

[0059] Meanwhile, the peripheral cutting mechanism 4 is movably mounted on the gantry 1 and located on one side of the turntable mechanism 2. The peripheral cutting mechanism 4 is used to perform turning machining on the periphery of the casting.

[0060] Specifically, the peripheral cutting mechanism 4 also has the ability to move up and down and to move laterally. On the one hand, the cutting position on the periphery of the casting can be changed by the lifting motion, and on the other hand, the feed amount of the turning action can be changed by the lateral movement. At this time, by adjusting the path of the peripheral cutting mechanism 4, the periphery of the casting can be turned from bottom to top along the length direction of the casting or from top to bottom along the length direction of the casting.

[0061] Furthermore, there are at least two sets of peripheral cutting mechanisms 4, and multiple sets of peripheral cutting mechanisms 4 are arranged at intervals around the turntable mechanism 2.

[0062] For example, the specific number of peripheral cutting mechanisms 4 can be two, three or four, etc. Multiple peripheral cutting mechanisms 4 arranged at intervals around the turntable mechanism 2 can perform turning processing on the peripheral side of the casting in multiple directions. Since the large wind turbine main shaft casting has a long structural length, the processing efficiency of the casting can be significantly improved.

[0063] For example, in one embodiment of this invention, two sets of peripheral cutting mechanisms 4 are provided. The two sets of peripheral cutting mechanisms 4 are respectively set on the two columns of the gantry frame 1. At this time, one set of peripheral cutting mechanisms 4 can be set to perform turning from the top of the casting downwards, while the other set of peripheral cutting mechanisms 4 can be set to perform turning from the bottom of the casting upwards. This can shorten the cutting time by half and significantly improve the processing efficiency.

[0064] It is understood that the specific number of peripheral cutting mechanisms 4 can be adjusted according to actual needs. No limit is placed on the specific number of peripheral cutting mechanisms 4 here. Regardless of the specific number of peripheral cutting mechanisms 4, it should be included in the scope of interpretation of this application.

[0065] Reference Figure 2 In some specific embodiments, the end face cutting mechanism 3 includes a first transverse module 31, a first lifting module 32, and a first cutting head 33.

[0066] The first transverse module 31 is disposed on the gantry 1, the first lifting module 32 is disposed on the first transverse module 31, and the first cutting head 33 is disposed on the first lifting module 32. The first transverse module 31 is used to drive the first cutting head 33 to move laterally through the first lifting module 32, and the first lifting module 32 is used to drive the first cutting head 33 to move up and down.

[0067] Specifically, the first transverse module 31 is used to output transverse reciprocating motion, while the first lifting module 32 is used to output lifting motion. Typically, both the first transverse module 31 and the first lifting module 32 adopt a linear module structure, such as a linear motor module or a lead screw slide module. Each linear module is equipped with a slide capable of reciprocating motion. Here, as long as a linear module capable of stably and accurately outputting linear reciprocating motion is used, it should be included in the scope of this solution. No specific model of the first transverse module 31 and the first lifting module 32 is restricted here.

[0068] Based on the above configuration, the first transverse module 31 is mounted on the crossbeam and positioned horizontally, the first lifting module 32 is mounted on the slide of the first transverse module 31 and positioned vertically, and the first cutting head 33 is mounted on the slide of the first lifting module 32 with its cutting edge facing vertically downward. Under the combined action of the first transverse module 31 and the first lifting module 32, the first cutting head 33 can perform cutting processing on the end face of the top of the casting in a rotating state. Furthermore, by controlling the displacement output by the first lifting module 32, the amount of processing on the end face of the casting can be precisely controlled, achieving a precise processing effect.

[0069] Continue to refer to Figure 2 In some embodiments, the peripheral cutting mechanism 4 includes a second lifting module 41, a second transverse module 42, and a second cutting head 43.

[0070] The second lifting module 41 is disposed on the gantry 1, the second transverse module 42 is disposed on the second lifting module 41, and the second cutting head 43 is disposed on the second transverse module 42. The second lifting module 41 drives the second cutting head 43 to move up and down through the second transverse module 42, and the second transverse module 42 is used to drive the second cutting head 43 to move laterally.

[0071] Specifically, the second lifting module 41 is used to output lifting motion, and the second transverse module 42 is used to output transverse reciprocating motion. Typically, both the second transverse module 42 and the second lifting module 41 adopt a linear module structure, such as a linear motor module or a lead screw slide module. Each linear module is equipped with a slide capable of reciprocating motion. As long as a linear module capable of stably and accurately outputting linear reciprocating motion is used, it can meet the turning requirements and should be included in the scope of this solution. No specific model of the second transverse module 42 and the second lifting module 41 is restricted here.

[0072] Based on the above configuration, the second lifting module 41 is mounted on the column, the second transverse module 42 is mounted on the slide of the second lifting module 41, and the second cutting head 43 is mounted on the slide of the second transverse module 42. The second cutting head 43 is positioned horizontally towards the periphery of the casting. Under the combined action of the second transverse module 42 and the second lifting module 41, the second cutting head 43 can move laterally to cut the periphery of the casting in a rotating state. At the same time, the second lifting module 41 drives the second cutting head 43 to move up and down, thereby turning the casting as a whole along the length of the casting to precisely control the amount of machining on the periphery of the casting and achieve a precise machining effect.

[0073] Based on the above settings, with the joint cooperation of the end face cutting mechanism 3 and the peripheral side cutting mechanism 4, the end face and peripheral side of the casting can be machined simultaneously, and the machining efficiency is significantly improved.

[0074] Furthermore, in practical applications, the overall weight of large wind turbine main shaft castings is usually measured in tons. Therefore, when placing the castings on the turntable mechanism 2, a gantry crane is typically used for hoisting and transfer. However, when adjusting the placement of the castings on the turntable mechanism 2, the castings are prone to swaying. At this time, operators need to be near the castings to direct and coordinate. However, since this solution is equipped with an end face cutting mechanism 3 and multiple sets of peripheral cutting mechanisms 4, the hoisting and adjustment space near the turntable mechanism 2 is too narrow. If the castings sway, they are prone to colliding with other parts of the equipment or causing danger to personnel.

[0075] Based on this, in some embodiments, reference is made to Figure 3 The processing equipment also includes a displacement mechanism 5, which includes a track assembly 51, a moving platform 52, and a drive assembly 53.

[0076] The track assembly 51 is laid on the ground. Typically, the track assembly 51 can be a heavy-duty guide rail to meet the requirements of bearing castings with large tonnage. It is understood that no specific model of the track assembly 51 is restricted here.

[0077] In addition, the mobile platform 52 is slidably mounted on the track assembly 51, and the turntable mechanism 2 is mounted on the mobile platform 52.

[0078] Specifically, the mobile platform 52 has a rectangular block structure and is horizontally positioned. It has a slider at the bottom and the slider slides into the track assembly 51. At this time, the mobile platform 52 can obtain the degree of freedom of movement to move back and forth along the length direction of the track assembly 51 by sliding into the track assembly 51 through the slider.

[0079] Based on this, the drive assembly 53 is connected to the mobile platform 52 to drive the mobile platform 52 to reciprocate on the track assembly 51, so that the mobile platform 52 moves from inside the gantry 1 to outside the gantry 1 or moves the mobile platform 52 from outside the gantry 1 to inside the gantry 1.

[0080] Specifically, the drive assembly 53 is used to output power. In some embodiments, the drive assembly 53 includes a servo motor, a reducer, and a drive gear. The mobile platform 52 is hollow inside, and the servo motor and the reducer are respectively installed inside the mobile platform 52. The input shaft of the reducer is connected to the output shaft of the servo motor, and the drive gear is installed on the output shaft of the reducer. The servo motor can output torque stably and accurately. Based on this, the torque is amplified by the reducer and then transmitted to the drive gear, so that the drive gear can rotate under a large torque.

[0081] Meanwhile, multiple drive teeth are arranged sequentially along a straight line on the track assembly 51. One end of the track assembly 51 extends into the gantry 1, and the drive gear meshes with the drive teeth. When the drive gear rotates, it can drive the moving platform 52 to move back and forth on the track assembly 51.

[0082] In this embodiment, the drive component 53 adopts a linear module in the form of a motor lead screw. Specifically, by connecting the sleeve on the lead screw to the moving platform 52, the motor is started, and the lead screw can drive the sleeve to move back and forth when it rotates, thereby driving the moving platform 52 to move back and forth. It is understood that the specific structure of the drive component 53 can be adjusted according to actual needs, and no specific restrictions are made here.

[0083] Based on the above settings, by activating the drive component 53, the mobile platform 52 can be driven to move back and forth on the track component 51, with efficient and rapid operation. At this time, the mobile platform 52 includes at least the following two states:

[0084] On the one hand, when it is necessary to hoist the casting onto the turntable mechanism 2, the moving platform 52 can be driven away from the gantry 1, so that the turntable mechanism 2 is moved to the outside of the gantry 1. At this time, there is a larger operating space around the turntable mechanism 2. Therefore, even if the casting shakes significantly during hoisting, it is not easy to collide with other mechanisms. In addition, the larger operating space also makes it easier for operators to command and coordinate more safely, and the safety of the equipment is significantly improved.

[0085] On the other hand, when the casting needs to be machined, the drive assembly 53 is activated, which drives the moving platform 52 to move into the gantry 1. Then the turntable mechanism 2 can be activated, which drives the casting to rotate. The end face cutting mechanism 3 and the peripheral cutting mechanism 4 then perform turning machining on the casting.

[0086] Furthermore, during the turning process, the casting rotates at a high speed, and there is usually a certain error between the geometric center of the casting and the center of rotation. This will cause the moving platform 52 to shake, which will have a certain impact on the safety of the machining process.

[0087] Based on this, refer to Figure 3 and Figure 4 To further optimize the safety of the equipment, the processing equipment provided in this embodiment also includes a locking mechanism 6, which includes a locking telescopic cylinder 61 and a locking block 62.

[0088] The locking telescopic cylinder 61 is set on the ground and adjacent to the track assembly 51. Usually, a fixed bracket can be installed on the ground and the locking telescopic cylinder 61 can be installed on the fixed bracket to achieve stable assembly. At this time, the locking telescopic cylinder 61 can be a pneumatic cylinder or a hydraulic cylinder, both of which can output reciprocating motion. The specific structure of the locking telescopic cylinder 61 is not limited here. In this embodiment, a hydraulic cylinder with a large thrust is selected as an example.

[0089] At the same time, the locking block 62 is connected to the telescopic rod of the locking telescopic cylinder 61, and a locking groove 621 is provided on one side of the moving platform 52. The locking telescopic cylinder 61 drives the locking block 62 to engage with the locking groove 621.

[0090] Specifically, the locking block 62 is fixedly connected to the telescopic rod, and the locking groove 621 is recessed from the outside to the inside on one side wall of the moving platform 52. The opening contour of the locking groove 621 is adapted to the outer contour of the locking block 62. When the moving platform 52 moves to the gantry 1, the locking block 62 and the locking groove 621 are positioned opposite each other. By activating the locking telescopic cylinder 61, the locking block 62 can be driven to move and insert into the locking groove 621.

[0091] When the locking block 62 is inserted into the locking slot 621, the locking block 62 restricts the moving platform 52 to rest on the track assembly 51, thereby locking the moving platform 52; in addition, when the locking block 62 is pulled out of the locking slot 621, the moving platform 52 is released, and the moving platform 52 can continue to move on the track assembly 51.

[0092] Based on the above settings, the locking mechanism 6 can lock and fix the mobile platform 52, thereby making it less likely for the mobile platform 52 to shake during casting processing, and further optimizing and improving the safety of the equipment.

[0093] Optionally, there are multiple sets of locking mechanisms 6, and multiple locking slots 621 are provided to match the number of locking mechanisms 6. The multiple locking slots 621 are located on opposite sides of the mobile platform 52, and the multiple sets of locking mechanisms 6 are respectively inserted and cooperated with the multiple locking slots 621.

[0094] For example, the number of locking mechanisms 6 can be two, three or four, etc. Multiple locking mechanisms 6 are located on opposite sides of the track assembly 51, and correspondingly, multiple locking slots 621 are located on opposite sides of the moving platform 52. At this time, by connecting multiple locking mechanisms 6 with multiple locking slots 621 respectively, the movement restriction of the moving platform 52 can be further improved, and the locking effect can be further optimized and improved.

[0095] It is understood that the specific number of locking mechanisms 6 can be adjusted according to actual needs. There is no limit to the specific number of locking mechanisms 6 here. In this embodiment, two sets of locking mechanisms 6 are set as an example.

[0096] Furthermore, continue to refer to Figure 4 The locking block 62 has a tapered guide 611 at one end facing the locking groove 621, and the groove wall of the locking groove 621 has a tapered concave surface that matches the tapered guide 611.

[0097] Based on the above configuration, during the process of inserting the locking block 62 into the locking groove 621, the tapered guide 611 and the tapered concave surface can slide and abut against each other, thereby pushing the moving platform 52 to adjust its stopping position until the locking block 62 is fully embedded in the locking groove 621. At this time, the matching tapered concave surface and tapered guide 611 can ensure that the moving platform 52 finally stops at the precise position, so as to ensure that the end face cutting mechanism 3 and the peripheral cutting mechanism 4 can simultaneously achieve precise machining actions.

[0098] In actual processing, a lot of metal shavings are easily generated. These shavings usually splatter around the turntable mechanism 2 and need to be cleaned regularly. Otherwise, excessive accumulation can affect normal processing operations. In addition, cleaning takes time, usually more than half an hour by hand, which also affects the overall processing efficiency.

[0099] Based on this, refer to Figure 5 and Figure 6 To overcome the obstacles caused by metal shavings to this solution, the processing equipment provided in this application embodiment also includes a collection tank 7 and a lifting assembly 8.

[0100] The collection tank 7 has a clearance hole 71 in the middle. The collection tank 7 is rotatably mounted on the moving platform 52, and the moving platform 52 passes through the clearance hole 71. The lifting component 8 is mounted on the moving platform 52 and connected to the collection tank 7. The lifting component 8 is used to drive the collection tank 7 to tilt or lie flat. The collection tank 7 has a chip outlet 72 on one side. When the collection tank 7 is tilted, metal chips are discharged from the chip outlet 72.

[0101] Specifically, in one embodiment, the collection tank 7 is a rectangular sheet metal tank structure with its top recessed from top to bottom to form a receiving cavity. The clearance hole 71 is provided through the bottom wall of the collection tank 7. In this case, a horizontally extending pivot can be provided between the collection tank 7 and the moving platform 52 so that the collection tank 7 can rotate up and down based on the pivot.

[0102] Based on this, when the lifting component 8 drives the collection tank 7 to tilt, one side of the collection tank 7 moves upward, while the opposite side is at a low point. At this time, the chip outlet 72 is located on the side plate where the collection tank 7 is at its low point. Under the guidance of gravity, the metal chips can be discharged from the chip outlet 72 by themselves, thereby achieving rapid cleaning of metal chips and optimizing and improving the cleaning efficiency of metal chips.

[0103] In some embodiments, a baffle is detachably provided at the chip outlet 72. The baffle can open and close the chip outlet 72. When the chip outlet 72 is closed, it is beneficial to collect metal chips stably. When the chip outlet 72 is open, it is convenient to carry out the chip removal action, resulting in a better operating experience.

[0104] Furthermore, referring to Figure 5 and Figure 7 The side of the collection trough 7 near the chip outlet 72 is rotatably connected to the moving platform 52. The moving platform 52 is provided with an arc-shaped guide groove 521. The collection trough 7 is provided with a guide element 73 that is slidably disposed in the arc-shaped guide groove 521. In addition, the lifting assembly 8 includes a lifting telescopic cylinder, which is rotatably disposed on the moving platform 52, and the telescopic rod of the lifting telescopic cylinder is rotatably connected to the collection trough 7.

[0105] Specifically, the arc-shaped guide groove 521 is recessed on the outer wall of the moving platform 52, and the guide element 73 is a rod-shaped element that is inserted into the arc-shaped guide groove 521 and slides against its inner wall. Under the guiding action of the guide element 73 and the arc-shaped guide groove 521, the flipping action of the collection tank 7 can be guided, making the flipping action more stable.

[0106] In addition, the lifting telescopic cylinder can be a pneumatic cylinder or a pneumatic cylinder. The specific structure of the lifting telescopic cylinder is not limited here. In this case, the lifting telescopic cylinder can be installed on a hinge seat. At the same time, a hinge shaft is provided on the moving platform 52 for the hinge seat to be rotatably installed. With the cooperation of the two, the lifting telescopic cylinder can be rotatably connected to the moving platform 52. In addition, a hinge seat and a hinge shaft are also provided between the telescopic shaft of the lifting telescopic cylinder and the arc-shaped guide groove 521. With the cooperation of the two, the telescopic rod of the lifting telescopic cylinder can be rotatably connected to the collection groove 7. At this time, the lifting telescopic cylinder obtains the motion freedom to push the collection groove 7 to reciprocate.

[0107] Based on the above settings, by activating the lifting and telescopic cylinder, the collection tank 7 can be tilted or laid flat. The action is quick and efficient, and easy to control, which significantly improves the cleaning efficiency of metal shavings.

[0108] In some embodiments, since the collection tank 7 has an arc-shaped lifting trajectory, in order to avoid an excessive gap between the clearance hole 71 of the collection tank 7 and the moving platform 52, one side of the moving platform 52 is set as an arc-shaped extension surface to adapt to the moving trajectory of the collection tank 7, and to keep the gap between the clearance hole 71 and the moving platform 52 within a small size range to prevent metal shavings from leaking out of the clearance hole 71.

[0109] Reference Figure 5 It also includes a storage box 9, located outside the collection tank 7, with an opening at the top and positioned opposite the chip outlet 72.

[0110] Specifically, the storage box 9 can be placed on the ground. In some embodiments, the bottom of the storage box 9 is equipped with wheels, which can more conveniently transport metal shavings.

[0111] Based on the above setup, metal shavings can be centrally transported, further optimizing and improving the efficiency of metal shavings cleaning.

[0112] The large-scale wind turbine main shaft casting processing equipment provided in this application has the following beneficial effects:

[0113] 1. It can simultaneously process the end face and peripheral side of the casting, significantly improving processing efficiency;

[0114] 2. The movable turntable mechanism 2 facilitates safer hoisting of castings, significantly improving the safety of the equipment.

[0115] 3. Each time the mobile platform 52 moves away from the gantry 1, it can quickly clean up metal chips and significantly shorten downtime. While conveniently cleaning up metal chips, it also indirectly improves the processing efficiency of castings.

[0116] Therefore, the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them.
