Abstract

The present invention discloses a wind turbine stator welding surface processing machine tool, which relates to the field of machine tool processing technology. The main technical problem to be solved is that the wind turbine stator needs to be inspected every time before leaving the factory. However, for the inspection of non-standard wind turbine stator casings, personnel are required to inspect them one by one, and the inspection efficiency is low. The machine tool comprises a machine tool base and a positioning plate. A first auxiliary block and a second auxiliary block are arranged on both sides of the machine tool base. A first motor is arranged on the first auxiliary block; a first rotary hole is arranged on the side wall of the machine tool base, and a first clamping block is arranged on a side wall of the first auxiliary block facing the machine tool base; a second rotary hole is arranged through the first clamping block and the first auxiliary block, so that the bolt hole that is most difficult to inspect of the non-standard wind turbine stator casing is inspected, and the unqualified area is subjected to secondary processing, which reduces the time of multiple manual handling and greatly reduces the processing cost of the wind turbine stator casing.

Description

Technical Field

[0001] The invention relates to the technical field of machine tool processing, in particular to a wind power stator welding surface processing machine tool. Background Art

[0002] The fixed part of the first motor is called the stator, on which pairs of DC-excited static main magnetic poles are installed. Wind turbine stators are shipped from the factory as independent small structures and are customized according to customer needs. The shape and size of the wind turbine stator shells are adjusted for each batch, and these wind turbine stator shells need to be adjusted before leaving the factory. Wind turbine stators need to be inspected every time before leaving the factory. However, for non-standard wind turbine stator shells, inspection requires personnel to inspect them one by one, which is inefficient.

[0003] The wind turbine stator shell tested by this equipment is the final processed product, and its shell bolt holes have no processed lines. The complete wind turbine stator shell is composed of two or more shells, and the shells match each other. Conventional shell components are fixed together by bolts and other means to form a complete wind turbine stator shell. A more perfect approach is to assemble the shells by welding, resulting in part of the weld seam being inside the bolt hole. This situation occurs because both shells are provided with a bolt hole part, and only when they are assembled can they form a complete bolt hole. Therefore, it is very necessary to design a wind turbine stator welding surface processing machine tool. Summary of the Invention

[0050] A fixture device 17 is fixedly installed on the top of the machine tool base 8. The fixture device 17 is a standard mold and cannot be adjusted. Different fixture devices 17 need to be made for different wind turbine stators. The wind turbine stator shell is inserted into the fixture device 17. Since the shape of the fixture device 17 is made according to the shape of the wind turbine stator, the wind turbine stator is fixed after it fits into the fixture device 17. The welding parts of the wind turbine stator are all at the bolt holes of the wind turbine stator. The welding surface inspection is performed on the bolt holes of the wind turbine stator. The fixture device 17 is provided with a detection device with the same number of bolt holes on the wind turbine stator. The detection device includes a base 18, a fixed support rod 19 of the base 18, a lifting rod 20 installed on the top bearing of the support rod 19, a third motor 21 is provided in the end area of the lifting rod 20, and a detection head 22 is fixedly installed at the output end of the third motor 21. A plurality of electric control rods 23 are symmetrically arranged on the side wall, and a side grinding plate 24 is fixedly installed on the electric control rods 23. The detection head 22 is wide at the top and narrow at the bottom. The side grinding plate 24 is in close contact with the detection head 22 when not in operation, and does not contact the detection head 22 when in operation. A camera assembly 25 is arranged on one side of the detection equipment, a device block 26 is fixedly installed on the machine tool base 8, a fourth motor 28 is arranged in the device block 26, a displacement rod 27 is fixedly installed on the output end of the fourth motor 28, and the displacement rod 27 is fixedly connected to the camera assembly 25. A pressure sensor 29 and a bottom grinding plate 30 are fixedly installed on the bottom of the detection head 22. The bottom quarter area of the detection head 22 is a recessed area, and the bottom grinding plate 30 is arranged in the recessed area. A fixed rod 31 is arranged inside the detection head 22, and a lifting rod 32 is arranged on the fixed rod 31, and the lifting rod 32 is connected to the bottom grinding plate 30;

[0051] The lifting rod 20 is electrically connected to the first driving member;

[0052] The electric control rod 23 is electrically connected to the second driving member;

[0053] The lifting rod 32 is electrically connected to the third driving member;

[0054] The wind turbine stator welding surface processing machine tool also includes a positioning plate 1, which is used to support the above structure, and the worker fixes the machine tool through the positioning plate 1;

[0055] The wind turbine stator welding surface processing machine tool is equipped with a processing system, which is divided into a driving end and a detection end. The detection end includes a wind turbine stator module and a welding surface module, and the driving end includes a safety module and a maintenance module.

[0056] The first embodiment is:

[0057] The wind turbine stator housing is clamped into the fixture device 17 to fix the wind turbine stator housing. The positioning plate 1 is fixed to provide a stable environment for the processing of the wind turbine stator housing. The camera assembly 25 performs camera positioning adjustment, that is, the driving end drives the fourth motor 28 to move, the movement of the fourth motor 28 drives the displacement rod 27 to move, and the movement of the displacement rod 27 drives the camera assembly 25 to move;

[0058] The initial position of the lifting rod 20 is at the highest point, which is convenient for the placement of the wind turbine stator. The driving end drives the first driving member to move, and the movement of the first driving member drives the lifting rod 20 to descend. The descent of the lifting rod 20 drives the detection head 22 to descend, and the detection head 22 descends until it is inserted into the bolt hole of the wind turbine stator shell. If the welding surface in the bolt hole is smooth, the detection head 22 is inserted into the bolt hole in a completely fitting state. The pressure sensor 29 detects a value such as the preset N 额定 If the welding surface in the bolt hole is not smooth and has small particles produced by welding, the pressure sensor 29 installed at the bottom of the detection head 22 detects the pressure value N that is different from the set value. 额定 If there is no consistency, the processing system determines that the bottom inspection of the bolt hole of the wind turbine stator housing is unqualified. The welding surface module receives the transmission value of the pressure sensor 29 and confirms that the smoothness of the bottom of the bolt hole is unqualified. Then the maintenance module drives the third motor 21 to move. The movement of the third motor 21 drives the detection head 22 to rotate. The rotation of the detection head 22 drives the bottom grinding plate 30 at its bottom to grind the bottom of the bolt hole.

[0059] The grinding process is as follows: grinding at a fixed frequency, that is, the maintenance module sets a fixed time H, and the detection head 22 rotates for a period of time H, then the detection head 22 stops moving, and the above detection process is repeated until the bottom grinding plate 30 completes the grinding of the bottom of the bolt hole and the processing system determines that the smoothness of the bottom of the bolt hole is qualified;

[0060] Due to the irregular shape of the wind turbine stator casing, it cannot be inspected by conventional machine tools. Using a single device to inspect the bolt holes of the wind turbine stator casing requires manual judgment. At the same time, another device is required to perform secondary processing on the wind turbine stator casing, which has a high processing cost. The use of the above-mentioned processing equipment can reduce the processing cost and speed up the processing efficiency of the wind turbine stator.

[0061] The second embodiment is:

[0062] After the bottom processing of the bolt hole of the wind turbine stator housing is completed, the side wall of the bolt hole is processed. The maintenance module drives the electric control rod 23 to move. The movement of the electric control rod 23 drives the side grinding plate 24 to expand. The side grinding plate 24 contacts the entire outer wall of the side grinding plate 24 and the inner wall of the bolt hole. At this time, the side grinding plate 24 is in a state completely perpendicular to the bottom of the machine tool base 8. At this time, the number of rotations of the electric control rod 23 is the set value Z. If the wind turbine stator module detects that the number of rotations of the electric control rod 23 is less than Z, the detection end determines that the smoothness of the inner wall of the bolt hole is unqualified. At this time, the maintenance module drives the third motor 21 to move. The movement of the third motor 21 drives the detection head 22 to rotate. The rotation of the detection head 22 drives the side grinding plate 24 to grind the inner wall of the bolt hole. The grinding process is consistent with the above-mentioned bottom grinding process of the bolt hole.

[0063] If the wind turbine stator module detects that the number of revolutions of the electric control rod 23 is equal to Z, the detection end determines that the smoothness of the inner wall of the bolt hole is qualified;

[0064] When grinding the inner wall of the bolt hole, the safety module drives the lifting rod 32 to rise to prevent the bottom grinding plate 30 from over-processing the bottom of the bolt hole;

[0065] The above-mentioned first and second embodiments are combined to complete the inspection of the most difficult bolt holes of the non-standard wind turbine stator housing, and at the same time perform secondary processing on the unqualified areas, thereby reducing the time of multiple manual handling and significantly reducing the processing cost of the wind turbine stator housing.

[0066] The third embodiment is:

[0067] During the processing of the wind turbine stator casing, a large amount of impurities will be generated. Since there are too many grooves on the surface of the fixture device 17, the driving end drives the second motor 4 and the first motor 5 to rotate after the processing of the wind turbine stator casing is completed, and drives the machine tool base 8 to rotate, and then the fixture device 17 is flipped ninety degrees or one hundred and eighty degrees. The impurities on the surface of the fixture device 17 fall directly. At the same time, the driving end drives the pump to run. When the pump runs, air is extracted from the first row of through holes 15 and exhausted from the second row of through holes 16. The second row of through holes 16 is aligned with the fixture device 17 to further remove impurities on the surface of the fixture device 17 and prepare for the next wind turbine stator casing processing.
