Line drawing and grinding tool clamping device

Abstract

The invention provides a line drawing and grinding tool clamping device, which relates to the manufacturing technology of track equipment. In the present invention, a slidingly connected measuring rod and a sliding base are arranged, and a clamping body is arranged on the sliding base. The clamping body can reliably fix the line drawing tool and the grinding tool through its clamping arm, and the sliding base can drive the clamping body along the The measuring rod slides in the length direction, and the drawing tools and grinding tools clamped on the clamping body can also move along the length direction of the measuring rod, so as to ensure the accuracy of drawing lines, improve the efficiency of drawing lines, and improve the grinding efficiency. The stability of the tool avoids the deviation of the grinding head and ensures the accuracy of the groove and weld grinding, thereby reliably ensuring the product quality, which in turn helps to shorten the production cycle of rail vehicles and reduce production costs.

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
