Clamping device for line drawing and grinding tools

The invention provides a clamping device for line drawing and grinding tools, and relates to the field of rail equipment manufacturing. According to the clamping device, a measuring rod and a slidingbase which are slidably connected are arranged, a clamping main body is arranged on the sliding base, thus the clamping main body can reliably fix the line drawing tool and the grinding tool through clamping arms of the clamping main body; the sliding base can drive the clamping main body to slide in the length direction of the measuring rod; the line drawing tool and the grinding tool clamped onthe clamping main body can also move in the length direction of the measuring rod, accuracy of line drawing is ensured advantageously, and the line drawing efficiency is improved; and stability of thegrinding tool is improved, the problem of deviation of a grinding head is avoided, grinding accuracy of a groove and a weld seam is ensured, thus the product quality is ensured reliably, thus the production period of railway v
