[0012] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 、 2 As shown, a high-precision correction clamping device for processing a wind turbine bearing seat in this embodiment includes a central tube 1, and three circumferentially evenly distributed clamping bodies 2 are arranged on the outer circumference of the central tube 1. An adjusting rod 3 is inserted into the clamping body 2, and the adjusting rod 3 can move inside the clamping body 2 to achieve the extension and contraction of the adjusting rod 3. A plurality of adjustment holes 6 are respectively provided on the adjusting rod 3 and the clamping body 2, and the plurality of adjustment holes are evenly spaced along a straight line; after the adjusting rod is moved into position, that is, the sum of the lengths of the clamping body and the adjusting rod matches the diameter of the inner hole of the casting blank, a connecting bolt 7 is inserted into the adjusting hole 6 and a nut is tightened on the connecting bolt 7, so that the adjusting rod 3 is fixedly connected to the clamping body 2 to form a telescopic clamp. An inverted L-shaped support plate 4 is provided at the outer end of the adjusting rod 3, and the support plate 4 is fixedly connected to the adjusting rod 3 through a connecting plate 8, and the support plate is supported on the top of the casting blank. Horizontally arranged threaded holes are respectively provided on the support plate 4 and the connecting plate 8, and an adjusting bolt 5 is inserted into the threaded hole. The adjusting bolt 5 is rotated so that the end of the adjusting bolt 5 is pressed against the inner wall of the inner hole of the casting blank.

[0014] A handle 9 is provided on the clamp body 2 to facilitate lifting the clamp body.

[0015] The clamp body and the adjusting rod are both hollow rectangular tubes.

[0016] Based on the instability of the circumferential blank of a large casting, the operating steps of this application include the following:

[0017] Step 1: Measure the inner hole of the casting blank and preliminarily determine the inner hole size range.

[0018] Step 2: Adjust the lengths of the three adjusting rods according to the size range of the inner hole to ensure that the three adjusting rods are of the same length, and then fix them to the corresponding clamp bodies through connecting bolts.

[0019] Step 3: Move the correction clamping device to the inner hole of the casting blank, place it initially, and support the support plate on the top surface of the casting blank.

[0020] Step four: adjust the position of the correction clamping device, measure the distance between the inner wall of the hole of the casting blank and the center of the center tube at three adjusting rods, so that the distances at the three places remain consistent. Rotate the three adjusting bolts so that the adjusting bolts abut against the inner cavity of the hole of the casting blank, so that the correction clamping device is tightly connected with the casting blank.

[0021] Step five: hoist the casting blank and the correction clamping device together to the machine tool workbench, and the center tube is sleeved on the workbench core rod. Slowly lower the casting blank so that the bottom surface of the casting blank contacts the threaded backup on the machine tool. By centering the correction clamping device and the workbench, the rotational center of the casting blank is indirectly ensured to be located at the center of the workbench.

[0022] Step six: review the calibration upper plane, complete the workpiece correction work, and start the next machining process.

[0023] The center of the center tube is the center of the workpiece, and the center tube is arranged on the workbench core rod and quickly and accurately positioned at the center of the machine tool workbench.
