Clamping device for line drawing and grinding tools

Abstract

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 vehicles is shortened advantageously, and the production cost is lowered advantageously.

Description

technical field [0001] The invention relates to track equipment manufacturing technology, in particular to a line drawing and grinding tool clamping device. Background technique [0002] With the rapid development of the rail equipment manufacturing industry, especially the development of high-speed EMUs, welding technology has been widely applied to the rail equipment manufacturing industry; the aluminum alloy car bodies of EMUs are usually formed by welding, such as side walls, underframes, The roof and the like are formed by welding, so the welding quality directly affects the production cycle and manufacturing cost of the entire car body. [0003] At present, the car bodies of rail vehicles such as EMUs / subway vehicles are welded by aluminum alloy plates. The aluminum alloy sheet needs to be drawn and polished before welding to remove the oxide skin on its surface; after welding, the weld seam also needs to be polished, so drawing lines and grinding takes up a lot of ma...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, in the line drawing process, the operator usually draws the width by a certain distance, and connects two points to determine the position of the line, resulting in low efficiency of line drawing, and large errors in manual line drawing can easily lead to The drawing line is skewed; during the grinding process, the operator needs to hold the grinding tool for grinding, but the stability of the hand-held grinding tool is poor, and the grinding head is easy to deviate from the groove, weld, etc., and it is difficult to guarantee the product quality
