Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machining lathes, and particularly relates to an inclined body machining lathe. Background Technique

[0002] The inclined bed turning-milling compound machine tool is an automated machine tool with an inclined bed. The plane where the two guide rails of the inclined bed turning-milling compound machine tool intersect with the ground plane to form an inclined plane, and the angles are 30°, 45°, 60°, and 75°. The bed of the inclined bed turning-milling compound machine tool is in the shape of a right triangle. Obviously, in the case of the same guide rail width, the X-direction carriage of the inclined bed is longer than that of the flat bed. The practical significance applied to the lathe is that more tool positions can be arranged, so that a multi-station turret or a power east turret can be equipped, with the characteristics of high precision and high efficiency.

[0003] Among the existing inclined bed turning-milling compound machine tools on the market, the structure between the spindle casting and the lathe casting is generally a plane connection, and then vertically fixed and locked by bolts. Due to the inclination of the machining surface of the inclined bed turning-milling compound machine tool, in the existing spindle casting installation structure, the bolts mainly responsible for locking are easily subjected to a large gravity load under the action of the gravity of the spindle casting, and it is easy to cause the bolts to deform between the spindle casting and the lathe casting. Therefore, in view of these current situations, there is an urgent need to develop an inclined body machining lathe to meet the actual use needs. Content of the Utility Model
