Description

Technical Field

[0001] The utility model relates to the technical field of vertical numerical control lathes, in particular to a shield structure for a vertical lathe. Background Technique

[0002] With the gradual development of the machinery manufacturing industry, in the production and installation of mechanical equipment, there are strict requirements for the processing of parts. Among them, small parts such as round nuts and screws are particularly important in mechanical equipment parts and play a connecting role for internal parts of the machine. Therefore, when processing and producing such parts, the accuracy of their size has a stabilizing effect on the connection of the equipment. Usually, when processing such small parts, it is necessary to accurately adjust the diameter to be processed. However, during the processing process, a large amount of iron filings will splash and fly into the equipment interior. For this reason, a shield structure is usually set on the vertical lathe. For the convenience of transporting the shield, the shield usually has multiple components. During installation, each component is spliced and fixed one by one with bolts. During the installation process, a large number of bolts are required, which makes the installation cumbersome and thus reduces the installation and disassembly efficiency. Therefore, we propose a shield structure for a vertical lathe. Content of the Utility Model
