Correction jig

The invention discloses a correction jig, which comprises correction frames, wherein each correction frame comprises a correction base platform, a support frame and a correction thimble; the correction base platforms are horizontally arranged; limiting grooves are formed in the correction base platforms; the support frames are arranged on the correction base platforms; the correction thimbles vertically penetrate through the support frames, and are positioned over the limiting grooves; the limiting grooves are used for fixing target support bases or middle connecting rods; the correction thimbles downwards move vertically into grooves of the target support bases to correct abnormal parts of the grooves. The correction jig is easy to operate and high in correction accuracy, and in a correction process, the consumed time is short, and the correction workload is low.
