Numerical control dual-head dual-face lock opening milling machine

Abstract

The invention discloses a numerical control dual-head dual-face lock opening milling machine, and relates to the technical field of numerical control turning milling machining. The machine mainly comprises a rack, and a feeding channel in the rack, two milling units are mounted on the rack and are located on the two sides of the feeding channel, each milling unit comprises a stand column, a pressing mechanism and a milling head mechanism, the stand columns are located on one side of the feeding channel, the pressing mechanisms and the milling head mechanisms are vertically and slidingly mounted on the stand columns, each milling head mechanism comprises a power box in sliding connection with the corresponding stand column and two milling head assemblies mounted on the output end of the power box, the side wall of one side, close to the feeding channel, of each stand column is provided with a milling deep stop iron mechanism, the pressing mechanisms are located above the milling deep stop iron mechanisms, and the two milling head assemblies are located on the two sides of the milling deep stop iron mechanism. Two heads of steel are milled, a dual-head milling operation manner is achieved in the related field, the occupied area of the machine is reduced, machining is more stable, and efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of numerical control turning and milling, in particular to a numerical control double-head and double-sided locking milling machine. Background technique [0002] The lock milling machine, also known as the lock machine, is mainly used in the milling operation of the steel end in the field of steel structure, especially the milling operation of the end of H-beam or I-beam. At present, domestic locking milling machines can only mill one side or both sides of a single end of steel. When it is necessary to mill one side or both sides of the other end of steel, the steel needs to be turned around or reversed to complete. Double-head milling operations. In order to solve this problem, the commonly used method in the field is to install a transfer roller table between the two locking machines. After the steel is processed at one end, it is then transferred to the other locking machine for processing, although the...

Problems solved by technology

In order to solve this problem, the commonly used method in the field is to install a transfer roller table between the two locking machines. After the steel is processed at one end, it is then transferred to the other locking machine for processing, although the complicated reversing problem can be avoided. , but this operation method will increase the overall floor area of ​​the equipment after all, especially for the case of long steel, it will greatly occupy the layout of the factory building, and when the steel is processed at both ends, it needs to be forwarded and reversed. On the one hand, it increases the difficulty of control, on the other hand, the transmission stability cannot be guaranteed
