Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a device for machining oblique holes in wind turbine bases. Background Technology

[0002] The wind turbine base is a key support structure for wind power generation equipment. It is usually made of reinforced concrete or steel structure and is used to fix the bottom of the wind turbine tower to ensure the stability of the whole machine in extreme weather and long-term operation.

[0003] As the core component supporting the wind turbine generator set, the accuracy of the machining of the inclined holes in the wind turbine base directly affects the verticality of the tower installation and the overall structural stability.

[0004] However, due to the special structure of the wind turbine base, conventional lathes will interfere with the wind turbine base during processing, resulting in processing difficulties and obvious shortcomings. Utility Model Content

[0005] To address the issue that conventional lathes are unsuitable for machining oblique holes in wind turbine bases, this application provides a device for machining oblique holes in wind turbine bases.

[0006] The wind turbine base inclined hole processing device provided in this application adopts the following technical solution: A device for machining oblique holes in wind turbine bases includes a machine tool body and a spindle box assembly movably arranged on the machine tool body. A support frame is rotatably mounted on the machine tool body. A worktable for placing the wind turbine base and a clamping assembly for holding the wind turbine base are arranged on the support frame. A deflection assembly for driving the worktable to rotate is also arranged on the machine tool body.

[0007] By adopting the above technical solution, the wind turbine base is placed on the workbench, and then the clamping component firmly clamps the wind turbine base. The deflection component drives the wind turbine base to rotate to an inclined state through the workbench, so that the spindle box assembly can process the inclined hole on the wind turbine base, which is suitable for the processing of inclined holes in the special structure of the wind turbine base.

[0008] Optionally, the clamping assembly includes a mounting side plate arranged on a support frame, a clamping hydraulic cylinder electrically connected to the control system is hinged to the mounting side plate, a slider is hinged to the piston rod of the clamping hydraulic cylinder, a horizontal groove is provided on the mounting side plate, the slider slides in the groove, and a sleeve for clamping the wind turbine base is arranged on the slider.

[0009] By adopting the above technical solution, the control system starts the clamping hydraulic cylinder, the piston rod of the clamping hydraulic cylinder retracts, thereby driving the slider to slide horizontally in the slide groove, and the slider can drive the jacket to approach the wind turbine base and clamp it.

[0010] Optionally, the deflection assembly includes a deflection hydraulic cylinder hinged to the machine tool body and electrically connected to the control system, wherein the piston rod of the deflection hydraulic cylinder is hinged to the support frame.

[0011] By adopting the above technical solution, the piston rod of the deflection hydraulic cylinder extends or retracts, thereby driving the wind turbine base on the workbench through the support frame to achieve angle adjustment.

[0012] Optionally, the side wall of the machine tool body is provided with an arc-shaped deflection guide rail, and the support frame is provided with a deflection guide block that extends into the deflection guide rail and slides with it.

[0013] By adopting the above technical solution, the deflection guide block and the deflection guide rail slide together, thereby guiding the rotation of the wind turbine base on the work platform.

[0014] Optionally, a frustum-shaped positioning platform is arranged on the workbench, and the wind turbine base is fitted onto the positioning platform.

[0015] By adopting the above technical solution, the positioning platform plays a role in positioning the wind turbine base, which facilitates the precise clamping of the subsequent sleeve.

[0016] Optionally, the positioning platform is made of hard rubber.

[0017] By adopting the above technical solution, during the process of the wind turbine base sliding onto the positioning platform, the two will inevitably have a small collision. The positioning platform, made of hard rubber, is not easily damaged on the surface during the collision, and can also ensure positioning accuracy.

[0018] Optionally, the bottom of the machine tool body is funnel-shaped with an opening at the lowest point. A support plate is hinged to the bottom of the machine tool body relative to the bottom opening. A rotating sleeve is also hinged to the bottom of the machine tool body. A fastening screw is threaded onto the rotating sleeve. A fastening nut for pressing against the rotating sleeve is threaded onto the fastening screw. A slot is provided on the support plate. The fastening screw passes through the slot and is provided with a stop block. The stop block is used to press against the side of the support plate opposite to the rotating sleeve.

[0019] By adopting the above technical solution, when the machine tool body is loaded with a large amount of processing waste, the worker can manually loosen the fastening nut, thereby causing the fastening screw to disengage from the slot and the tray to rotate. This opens the opening at the bottom of the machine tool body, allowing the waste inside the machine tool body to fall from the bottom outlet into the loading container placed below, thus easily and conveniently removing the waste.

[0020] Optionally, the pallet is provided with an elastic sealing ring that abuts against the opening at the bottom of the machine tool body.

[0021] By adopting the above technical solution, the elastic sealing ring helps to improve the sealing performance between the pallet and the bottom opening of the machine tool body, reducing the possibility of coolant leakage during the processing.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The wind turbine base is placed on the workbench, and then the clamping component firmly clamps the wind turbine base. The deflection component drives the wind turbine base to rotate to an inclined state through the workbench. In this way, the spindle box assembly can process the inclined hole on the wind turbine base, which is suitable for the processing of inclined holes in the special structure of the wind turbine base. 2. The control system starts the clamping hydraulic cylinder, the piston rod of the clamping hydraulic cylinder retracts, thereby driving the slider to slide horizontally in the slide groove, and the slider can drive the jacket to approach the wind turbine base and clamp it. 3. When the machine tool body is loaded with a large amount of machining waste, the worker manually loosens the fastening nut, thereby causing the fastening screw to disengage from the slot and the support plate to rotate. This opens the opening at the bottom of the machine tool body, allowing the waste inside the machine tool body to fall from the bottom outlet into the loading container placed below, thus easily and conveniently removing the waste.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a device for machining oblique holes in wind turbine bases.

[0029] Reference Figure 1The wind turbine base inclined hole machining device includes a machine tool body 1 and two spindle box assemblies 2 movably arranged on the machine tool body 1. The two spindle box assemblies 2 are symmetrically distributed about the vertical center line of the machine tool body 1. The spindle box assembly 2 includes a servo motor, a gearbox and a boring bar. The front end of the boring bar is equipped with a tool holder interface.

[0030] Reference Figure 1 The machine tool body 1 is equipped with multiple hydraulic outriggers that are electrically connected to the control system. The multiple hydraulic outriggers work together to adjust the overall height of the processing device, which facilitates the loading and unloading of the wind turbine base.

[0031] Reference Figure 1 and Figure 2 The machine tool body 1 has a rotating frame with a support frame 3, and cross roller bearings are arranged at the rotating frame. The support frame 3 is welded from multiple high-strength steel pipes, and a horizontal worktable 4 is welded on the support frame 3. The worktable 4 is used to place the wind turbine base.

[0032] Reference Figure 1 and Figure 2 The workbench 4 is equipped with a frustum-shaped positioning strip. The positioning table 12 is made of hard rubber and is used to position the wind turbine base. During the processing, the wind turbine base is fitted onto the positioning table 12.

[0033] Reference Figure 1 and Figure 2 The support frame 3 is equipped with a clamping assembly for clamping the wind turbine base. The clamping assembly includes a side plate welded to the support frame 3. Two clamping hydraulic cylinders 6, which are electrically connected to the control system, are hinged to the side plate 5.

[0034] Reference Figure 1 and Figure 2 The mounting side plate 5 has horizontally opened sliding grooves 51 on both opposite sides. The piston rod of each clamping hydraulic cylinder 6 is hinged with a slider 7. Each slider 7 corresponds to a sliding groove 51 and slides with it. A clamp 8 for clamping the wind turbine base is welded on the slider 7.

[0035] Reference Figure 1 and Figure 2 The control system starts the clamping hydraulic cylinder 6, and its piston rod retracts. During the retraction process, the clamping hydraulic cylinder 6 itself rotates slightly, and at the same time drives the slider 7 to slide in the corresponding slide groove 51. The slider 7 drives the clamp 8 to approach the wind turbine base and clamp it.

[0036] Reference Figure 1 and Figure 2 The machine tool body 1 is also equipped with a deflection assembly for driving the worktable 4 to rotate. The deflection assembly includes a deflection hydraulic cylinder 9 that is hinged to the machine tool body 1 and electrically connected to the control system. The piston rod of the deflection hydraulic cylinder 9 is hinged to the support frame 3.

[0037] Reference Figure 1 and Figure 2 A circular arc-shaped deflection guide rail 10 is bolted to the side wall of the machine tool body 1. The circle of the deflection guide rail 10 is located on the rotation center line of the support frame 3. A deflection guide block 11 is bolted to the support frame 3, extending into the deflection guide rail 10 and slidingly engaging with it.

[0038] Reference Figure 2 and Figure 3 The bottom of the machine tool body 1 is funnel-shaped with an opening at the lowest point. A support plate 13 is hinged to the bottom of the machine tool body 1 at the bottom opening. An elastic sealing ring 18 is adhered to the support plate 13 to abut against the bottom opening of the machine tool body 1.

[0039] The bottom of the machine tool body 1 is also hinged with a rotating sleeve 14. The rotating sleeve 14 is threaded with a fastening screw 15. The fastening screw 15 is threaded with a fastening nut 16 for pressing against the rotating sleeve 14. The support plate 13 has a slot 131. The fastening screw 15 passes through the slot 131 and is welded with a stop block 17. The stop block 17 is used to press against the side of the support plate 13 facing away from the rotating sleeve 14.

[0040] Reference Figure 2 and Figure 3 When the machine tool body 1 is filled with a large amount of processing waste, the worker manually loosens the fastening nut 16, thereby causing the fastening screw 15 to disengage from the slot 131. The support plate 13 rotates, thus opening the bottom of the machine tool body 1. The waste inside the machine tool body 1 can fall from the bottom outlet into the loading container placed below, thus easily and conveniently removing the waste.

[0041] The implementation principle of the wind turbine base inclined hole processing device in this application embodiment is as follows: the worker uses a hoist to lift the wind turbine base onto the positioning platform 12 on the workbench 4, and then the control system starts the clamping hydraulic cylinder 6. Its piston rod retracts. During the retraction process, the clamping hydraulic cylinder 6 itself rotates slightly, and at the same time drives the slider 7 to slide in the corresponding slide groove 51. The slider 7 drives the clamp 8 to approach the wind turbine base and clamp it.

[0042] Then the piston rod of the deflection hydraulic cylinder 9 extends or retracts, thereby driving the wind turbine base on the worktable 4 through the support frame 3 to achieve angle adjustment, which is then suitable for the machining of inclined holes on the wind turbine base.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
