Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser cutting processing of rear roof skin of public buses, in particular to a device for cutting locating pins of a bracket of rear roof skin. Background Art
[0002] The bus rear roof skin refers to the covering material installed on the rear roof of the bus. This skin is usually made of metal or fiberglass composite materials and is used to protect the vehicle's internal equipment and passenger area.
[0003] Due to the low target output of the rear roof skin of the bus, in order to reduce the cost of mold production, after the mold is drawn, a five-axis laser is used to cut part of the contour and part of the hole of the product for the first time, and then the mold is flanging and shaping. After flanging and shaping, if the contour and hole of the product are completely cut, it will cause contour deviation and hole deformation. Therefore, it is required to use a five-axis laser to cut the remaining contour and part of the hole of the product for the second time to ensure the quality of the product. Usually, two sets of cutting brackets need to be made: a cutting bracket after drawing and a cutting bracket after flanging. The cutting bracket after drawing has no product holes and no positioning pins, and the cutting bracket after flanging has holes, and the cutting bracket needs to be positioned with positioning pins. No solution has been proposed for related technical problems. Utility Model Content
