Problems solved by technology

[0004] At present, due to the structure of the bottom profile of the car body, the general milling (grinding) device can only complete the surface milling and grinding of the profile, but the inner cavity of the profile cannot be milled stably. This is because the common milling (grinding) device Usually the surface of the profile is ground, but when the inner cavity of the aluminum profile is manually ground and milled, the inner cavity of the aluminum profile is in the blind spot of human vision, the manual operation is inconvenient, the quality of the grinding and milling is unstable, and the grinding and milling cannot be guaranteed deep stability control

Abstract

The invention relates to the technical field of milling equipment, in particular to a milling device for milling an inner cavity of a profile and a milling method. According to the milling device formilling the inner cavity of the profile, a base is used for fixing the profile; a milling table is movably arranged between the base and the profile, a milling cutter is arranged on the milling table,and a cutter head of the milling cutter extends into the inner cavity of the profile to mill the inner cavity of the profile; a three-axis drive mechanism is connected with the base and the milling table and is used for driving the milling feed of the milling cutter. Based on the device, the milling method is provided. According to the device and the method, the milling cutter is controlled to penetrate into the inner cavity of the profile from the lower part of the profile through three-axis linkage, smooth transition between a polished milling surface and a non-polished milling surface is ensured through the three-axis linkage, the surface quality of the polished milling surface is ensured, accurate control over the length and depth of the polished milling can be realized, the product construction quality is stable, and the reliability is high, so that the milling quality and the stability of milling the inner cavity of the profile are improved.

Description

technical field [0001] The invention relates to the technical field of milling equipment, in particular to a milling device and a milling method for milling an inner cavity of a profile. Background technique [0002] Milling refers to the use of rotating multi-edged tools to cut profiles and is a highly efficient processing method. During the milling operation, the milling tool rotates as the main movement, and the profile moves as the feed motion; in addition, the profile can also be fixed, but at this time the rotating tool must also move, that is, the tool is used to complete the main motion and feed motion at the same time . [0003] When the EMU is undergoing maintenance, after the installation position of the inner cavity of the profile at the bottom of the aluminum alloy car body is fixed with bolts for a long time, the bolts will cause wear marks and indentations on the contact surface of the inner cavity of the aluminum profile. In order to remove the wear marks an...
