Description

Technical Field

[0001] This utility model relates to a special tooling clamp for casting integrated bearing housing of wind turbine generator, belonging to the technical field of special tooling clamps for casting. Background Technology

[0002] Slewing bearing housings are large and extra-large bearing housings with special construction that can withstand comprehensive loads. They are characterized by compact structure, sensitive rotation, and convenient installation and maintenance. Where there is a bearing, there must be a support point. The internal support point of the bearing is the shaft, and the external support is the bearing housing. When machining the integrated bearing housing of a wind turbine generator, special casting tooling fixtures are required.

[0003] Chinese Patent Publication No. (CN 215470297 U) discloses a casting processing equipment for bearing seats, including a worktable. Side plates are symmetrically installed on both sides of the worktable, and a top plate is mounted between the side plates. A support seat is provided between the side plates, and a placement groove is provided in the middle of the support seat. Clamping plates are provided around the placement groove. A moving cavity is provided inside the worktable, and a moving rod is installed in the moving cavity. A top rod is installed in the middle of the moving rod, and the top of the top rod extends out from the bottom of the placement groove. A grinding plate is provided above the placement groove. This utility model uses multiple clamping plates and telescopic springs to clamp and fix bearing seats of different sizes. The setting of lifting telescopic rod and electric slider is beneficial for adjusting the grinding plate.

[0004] The above-mentioned device mainly relies on the tension of the spring to clamp and fix the bearing seat. However, in actual use, due to the resonance characteristics of the spring itself, when the processing equipment processes the bearing seat, the spring may drive the clamping plate to move due to the contact of the processing equipment. This may cause the clamped bearing seat to move, which may affect the accuracy and stability of the processing of the bearing seat and make it inconvenient for operators to use.

[0005] To address this, a special tooling fixture for casting integrated bearing housings of wind turbine generators is proposed. Utility Model Content

[0006] In view of this, the present invention provides a special tooling clamp for the casting of the integrated bearing housing of a wind turbine generator, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-5 As shown, this utility model embodiment provides a special tooling fixture for wind turbine generator integrated bearing housing castings, including:

[0033] Positioning component 1 includes a base box 101. A first positioning plate 102 is fixedly installed on the rear side of the top of the base box 101, and a second positioning plate 103 is fixedly installed on the front side of the top of the base box 101. The first positioning plate 102 and the second positioning plate 103 have the same size, and the inner sides of the first positioning plate 102 and the second positioning plate 103 are both arc-shaped.

[0034] The clamping assembly 2 includes a servo cylinder 201, a first mounting bracket 202, and a second mounting bracket 203. The servo cylinder 201 is located on the left side of the base box 101, the first mounting bracket 202 is located on the left side of the inner cavity of the base box 101, and the second mounting bracket 203 is located on the right side of the inner cavity of the base box 101. A sliding rod 204 is fixedly installed in the inner cavity of the base box 101. Sliding blocks 205 are slidably connected to both the front and rear sides of the surface of the sliding rod 204. Connecting rods 206 are movably connected to both the left and right sides of the two sliding blocks 205. The other side of the four connecting rods 206... Both ends are movably connected to the inner side of the first mounting bracket 202 and the second mounting bracket 203. The top of the first mounting bracket 202 and the second mounting bracket 203 are both fixedly mounted with moving rods 207. The other end of the two moving rods 207 is fixedly mounted with clamping plates 208. The servo cylinder 201 is fixedly mounted on the left side of the base box 101. The right side of the servo cylinder 201 is fixedly connected to the left side of the first mounting bracket 202. The left side of the base box 101 is fixedly mounted with a cylinder control switch 209. The output end of the cylinder control switch 209 is electrically connected to the input end of the servo cylinder 201.

[0035] By setting up the clamping assembly 2, and extending through the servo cylinder 201, the first mounting bracket 202, in cooperation with the connecting rod 206 and the sliding block 205, causes the first mounting bracket 202 and the second mounting bracket 203 to drive the clamping plate 208 to fix the bearing seat inward. By adjusting the spacing of the clamping plates 208, it is easy to clamp and fix wind turbine integrated bearing seats of different sizes. This effectively avoids displacement of the wind turbine integrated bearing seat due to contact with the processing device during processing, thus affecting the normal processing of the wind turbine integrated bearing seat. It ensures the stability and accuracy of the bearing seat processing and facilitates the use of operators.

[0036] Example 2

[0037] like Figure 1-6 As shown, in one embodiment, protective pads 210 are fixedly installed on the surfaces of both clamping plates 208. The protective pads 210 are made of rubber. Slide grooves 211 are provided on the left and right sides of the top of the base box 101. The bottoms of the two clamping plates 208 are slidably connected to the inner cavities of the four slide grooves 211. Moving grooves 212 are provided on the left and right sides of the top of the base box 101. Two moving rods 207 pass through the inner cavities of the two moving grooves 212 and extend to the top of the base box 101. A limiting frame 213 is fixedly installed in the inner cavity of the base box 101. The tops of the two sliding blocks 205 are slidably connected to the inner side of the limiting frame 213. Mounting blocks 104 are fixedly installed on the left and right sides of the surface of the base box 101. The tops of the four mounting blocks 104 are threadedly connected to fixing bolts 105.

[0038] By setting the protective pad 210, scratches on the bearing housing surface can be avoided when the clamping plate 208 clamps the bearing housing. By setting the sliding groove 211, the movement of the clamping plate 208 can be limited to prevent it from shifting and affecting the clamping of the bearing housing. By setting the moving groove 212, the movement of the moving rod 207 can be limited to prevent it from shifting direction and thus ensuring the stability of clamping the bearing housing. By setting the limiting frame 213, the movement of the sliding block 205 can be limited to prevent it from deviating direction and affecting the clamping of the bearing housing. By setting the fixing bolt 105, the entire tooling can be disassembled and assembled, making it convenient for operators to install it in the required position.

[0039] In operation, the wind turbine integrated bearing housing is placed inside the first positioning plate 102 and the second positioning plate 103. Then, through the extension of the servo cylinder 201, the first mounting bracket 202 is pushed inward. The first mounting bracket 202 and its connected connecting rod 206 cooperate with each other, causing the sliding block 205 to move outward. As the sliding block 205 moves, it cooperates with the connecting rod 206 connected to the right side. At this time, the connecting rod 206 on the right side drives the second mounting bracket 203 to move to the left. The first mounting bracket 202 moves to the right, and the second mounting bracket 203 moves to the left, thereby causing the moving rod 207 to move inward synchronously. The moving rod 207 synchronously drives the clamping plate 208 to move inward, and the clamping plate 208 clamps both sides of the wind turbine integrated bearing housing.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
