[0023] As Figures 1-7 shown, the present utility model can reduce the deformation or damage of the planet carrier during the processing, improve the processing accuracy of the planet carrier, meet the requirements of high-quality wind power gearboxes, and provide the following technical solutions: A fixture for a wind power gearbox drive planet carrier, including a workbench 1; a product placement rack 2, which is vertically arranged on the upper side of the workbench 1; the product placement rack 2 includes bottom plates 21 arranged opposite to each other up and down, and the bottom plates 21 are connected by a plurality of connecting plates 22. A relief hole 211 is arranged in the middle of the bottom plates 21. A plurality of positioning shafts 4 are arranged circumferentially on the upper bottom plate 21. A driving device 5 for driving its lifting is arranged at the bottom of the positioning shaft 4, and the driving device 5 is connected to the bottom plate 21; a plurality of clamping parts 3 are arranged on the outer side walls of the connecting plates 22. The clamping part 3 includes a connecting bracket 31 connected to the connecting plate 22. A fixing block 32 is arranged on the upper side of the connecting bracket 31. A slider 33 is slidably arranged in the fixing block 32. A lead screw 34 is arranged between the slider 33 and the fixing block 32. An upper part of one end of the slider 33 is provided with a pressing block 35. A space for placing the wind power gearbox drive planet carrier 6 is formed above the bottom plates 21 between the plurality of pressing blocks 35, improving the processing efficiency, reducing the cost, and improving the product quality.

[0024] In this embodiment, as Figure 5 shown, a fixing sleeve 36 is sleeved on the end of the lead screw 34, and an operating handle 37 is arranged on the fixing sleeve 36 for convenient operation.

[0025] In this embodiment, as Figures 6-7 shown, a concave mounting groove 321 is arranged on the upper surface of the fixing block 32 along the length direction. Opposite inner side walls of the mounting groove 321 are provided with mounting protrusions 322. Clamping grooves 331 matching the mounting protrusions 322 are arranged on both sides of the slider 33, and the slider 33 moves smoothly.

[0026] In this embodiment, as Figure 6 shown, a first thread 323 matching the lead screw 34 is arranged at the bottom of the mounting groove 321, and the slider 33 moves through thread cooperation.
