Abstract

The invention discloses a special milling NC (numerical control) fixture machine tool of a ledge, which comprises a tool body, a right longitudinal milling head, a top milling head, a left longitudinal milling head, a numerical control feed box, a numerical control operation box, a guide-rail control box, a mast base, a left hydraulic fixture, an operating platform, a ledge workpiece and a right hydraulic fixture. The invention is characterized in that all mechanical processing procedures of a ledge are programmed into a computer by adopting a closed-loop control technique so as to realize the on-line monitoring and digital control of a human-machine interface; the machine tool disclosed by the invention has the function of error-correction alarm identification, and a floating supporting / adjusting mechanism is adopted in the left hydraulic fixture and the right hydraulic fixture, so that supporting points of the ledge workpiece are leveled off in the process of arranging the fixtures, the ledge is not easy to generate vibration phenomenon in the process of milling, and the three milling heads are milled simultaneously and conveniently; and because the left hydraulic fixture and the right hydraulic fixture are controlled to automatically clamp the ledge workpiece by a hydraulic system, and the ledge is clamped rapidly without moving, the machining precision of the ledge can be ensured.

Description

technical field [0001] The invention relates to a mechanical milling machine tool, in particular to a numerically controlled special fixture machine tool for groove side milling. Background technique [0002] The number of domestic coal mines is huge, and the improvement of the mechanization degree of coal mines will greatly promote the mechanization degree of the coal machinery industry, and the coal machinery industry will usher in a "golden period of development". Coal mining machinery belongs to special-purpose machinery, the application environment is very harsh, and the requirements for product automation technology are very high. The groove side workpiece is an important key part of the coal mine heavy-duty scraper conveyor, which requires high precision, complex geometry and difficult processing. Since the groove side is a large casting, the dimensional error and deformation are large, and the clamping is also difficult. At present, domestic large and medium-sized ...
