Description

Technical Field

[0001] This utility model relates to the field of bearing housing processing technology, and in particular, to a tooling fixture for processing the inner hole of a wind turbine bearing housing. Background Technology

[0002] A wind turbine is a device that converts wind energy into electrical energy. Wind power drives the blades to rotate, which in turn drives a generator to convert mechanical energy into electrical energy. The wind turbine bearing housing is a crucial component of a wind turbine. Its main function is to support the rotation of the main shaft and transmit the mechanical energy captured by the wind turbine. It also bears the complex force system generated by wind loads and the structure's own weight. The proper functioning of the wind turbine bearing housing directly affects the operating efficiency and reliability of the wind turbine.

[0003] When machining the inner hole of a wind turbine bearing housing, boring is usually used. During the boring process, the cutting edge generates cutting force when removing material, which causes the tool holder to be subjected to a thrust in the same direction as the machining. Correspondingly, the wind turbine bearing housing will be subjected to a thrust in the opposite direction along the inner hole axis. The existence of this thrust will cause the bearing housing to deform to a certain extent, thus affecting the machining accuracy of the wind turbine bearing housing.

[0004] Therefore, it is necessary for the inventors to improve the tooling fixtures for machining the inner hole of the wind turbine bearing housing in order to reduce the deformation of the wind turbine bearing housing and thus improve the machining accuracy of the inner hole.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please see Figures 1-4 This utility model provides a tooling fixture for machining the inner hole of a wind turbine bearing housing, applicable to the machining of a wind turbine bearing housing 100. Specifically, it is used to clamp and fix the wind turbine bearing housing 100 to facilitate boring operations. The wind turbine bearing housing 100 includes a bearing housing body 101 and two mounting seats 102 fixedly disposed on opposite sides of the bottom of the bearing housing body 101. During machining, the bearing housing body 101 is boring to machine the inner hole. The aforementioned tooling fixture for machining the inner hole of the wind turbine bearing housing includes a base 10 and a pressure bearing component 20. The base 10 is fixedly installed on the worktable of a boring machine. The pressure bearing component 20 includes a support plate 21 and a pressure plate 22 connected to each other. The support plate 21 is vertically arranged and fits against the end face of the bearing housing body 101. The pressure plate 22 is perpendicular to the support plate 21 and fits against the upper surface of the mounting base 102. A waist-shaped groove 221 is formed on the pressure plate 22 along the axial direction of the bearing housing body 101. A locking bolt 30 is installed on the pressure plate 22. The tail of the locking bolt 30 passes through the waist-shaped groove 221 and the mounting base 102 from top to bottom and is then fixedly connected to the base 10.

[0024] During clamping, the wind turbine bearing housing 100 to be bored is placed on the base 10. Then, the pressure-bearing component 20 is placed on the wind turbine bearing housing 100. By moving the pressure-bearing component 20, the support plate 21 is made to fit against one end face of the bearing housing body 100, and the pressure plate 22 is made to fit against the upper surface of the mounting base 102. At this time, the tail of the locking bolt 30 is passed through the waist-shaped groove 221 of the pressure plate 22 and the mounting base 102 from top to bottom and then fixedly connected to the base 10. Tightening the locking bolt 30 can press and fix the pressure plate 22 onto the mounting base 102. At this time, the base 10, the mounting base 102 and the pressure-bearing component 20 are relatively fixed. During the boring process, the boring tool gradually extends from the side of the wind turbine bearing housing 100 away from the support plate 21 into the bearing housing body 101. At this time, the support plate 21, which is placed vertically and fits against the bearing housing body 101, can support the bearing housing body 101. It can prevent the bearing housing body 101 from undergoing large-scale deformation when subjected to axial pressure, thereby improving the machining accuracy of the inner hole of the wind turbine bearing housing.

[0025] Please see Figure 4 In this embodiment, the base 10 is generally rectangular flat. A threaded hole 11 is provided on the upper surface of the base 10, and a through hole 1021 is provided on the mounting base 102. The through hole 1021 corresponds to the threaded hole 11. During installation, the tail of the locking bolt 30 passes through the through hole 1021 and is threaded into the threaded hole 11. Additionally, the base 10 has multiple parallel oblong holes 12. In this embodiment, there are four oblong holes 12, located at the four corners of the base 10. The extending direction of the oblong holes 12 is perpendicular to the axial direction of the bearing housing body 101. During connection, the user can use bolts to fix the base 10 onto the worktable of the boring machine through the oblong holes 12. The oblong holes 12 facilitate the user's adjustment of the position of the base 10 relative to the worktable, thereby adjusting the position of the wind turbine bearing housing 100 so that the boring tool can perform boring from a suitable position.

[0026] In this embodiment, the support plate 21 includes a first support portion 211 and a second support portion 212 connected to each other. The first support portion 211 is located above the pressure plate 22, and the second support portion 212 is located below the pressure plate 22. The first support portion 211 is in contact with the end face of the bearing housing body 101, and the second support portion 212 is in contact with the side wall of the mounting base 102. During the boring process, when the bearing housing body 101 deforms towards the first support portion 211 due to axial pressure, the contact relationship between the second support portion 212 and the mounting base 102 increases the difficulty of deformation of the first support portion 211 under stress, avoiding easy deformation of the first support portion 211 under pressure, thereby improving the machining accuracy.

[0027] Further, please refer to Figure 3The first support part 211 is provided with a relief groove 2111, which corresponds to the position of the hole to be opened on the bearing housing body 101 to avoid the movement of the boring tool.

[0028] Additionally, please see Figure 1 A reinforcing rib 222 is fixedly connected between the upper surface of the pressure plate 22 and the side wall of the support plate 21 to improve the connection strength between the pressure plate 22 and the support plate 21, making it more reliable. Each pressure plate 22 is provided with two reinforcing ribs 222, which are located on opposite sides of the waist-shaped groove 221.

[0029] By providing the waist-shaped groove 221, ample adjustable space is provided to the user, allowing one side of the support plate 21 to be adjusted to fit against the end face of the bearing housing body 101. In this embodiment, the waist-shaped groove 221 is opened at one end away from the support plate 21, forming the groove opening of the waist-shaped groove 221. Furthermore, the groove opening of the waist-shaped groove 221 is provided with a sloped structure 2211, which ensures that the pressure plate 22 can be quickly installed in place. Specifically, during installation, the user can first pass the locking bolt 30 downward through the mounting base 102 and pre-install it on the base 10. At this time, the user can push the pressure member 20 from one side of the mounting base 102, so that the pressure plate 22 is fitted onto the outside of the locking bolt 30 through the waist-shaped groove 221, and finally push the pressure plate 22 into place. Therefore, the sloped structure 2211 can guide the movement of the pressure plate 22, allowing the locking bolt 30 to quickly enter into the waist-shaped groove 221.

[0030] In addition, a washer 31 is fitted on the outside of the locking bolt 30. The washer 31 is sandwiched between the head of the locking nut 30 and the upper surface of the pressure plate 22 to prevent loosening.

[0031] The tooling fixture for machining the inner hole of the wind turbine bearing housing of this utility model supports the end face of the bearing housing body 101 through the support plate 21 of the pressure bearing 20, which effectively prevents the bearing housing body 101 from undergoing large deformation when subjected to axial pressure from the boring tool, thereby improving the machining accuracy of the inner hole of the wind turbine bearing housing. At the same time, the pressure bearing plate 22 and the mounting base 102 can be fixed on the base 10 simultaneously by the locking bolt 30. The design is reasonable, and the operation is simple and convenient, making it suitable for widespread use.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
