Abstract

The invention relates to the technical field of weld grinding, and provides an automatic grinding device and a grinding method. The automatic grinding device is used for grinding welds on bogie beams or side beams, and includes a pair of clamping mechanisms arranged oppositely at intervals. The mechanism includes a positioner and a grinding fixture. The positioner is connected with the grinding fixture. A pair of grinding fixtures are used to clamp the beam or side beam; the grinding tool is equipped with a force control sensor; the grinding positioning mechanism is used to position the beam or side beam. The welding seam; the grinding robot is provided with a mechanical arm, and the working end of the mechanical arm is respectively provided with a first connecting end and a second connecting end, the first connecting end is used for connecting the grinding positioning mechanism, and the second connecting end is used for connecting the grinding tool. Both the grinding positioning mechanism and the force control sensor are connected with the control system signal of the grinding robot. The invention has good welding seam grinding quality and high grinding efficiency.

Description

technical field [0001] The invention relates to the technical field of weld seam grinding, in particular to an automatic grinding device and a grinding method. Background technique [0002] At present, in production, in most cases, the process of grinding the weld seam is used to eliminate the stress concentration caused by the surfacing weld seam in the frame structure, and the welding seam reinforcement, uneven width and poor straightness of the weld seam are adopted. The parts that affect the appearance of the weld are ground into a smooth transition, which can eliminate the stress concentration phenomenon, prevent the bogie product from cracking at the corners of the structure, improve the fatigue resistance of the product, and prolong the service life of the bogie. At the same time, high-quality post-weld grinding can also provide better surface quality for subsequent processes (such as painting, processing, etc.), ensuring good appearance quality of welded parts. Ther...
