Three-Y-axis mirror image turn-milling center lathe bed and functional parts thereof

Abstract

The invention relates to the field of machine manufacturing, in particular to a turning and milling integrated lathe bed and related functional parts thereof, a main lathe bed is designed to be a rectangular thick frame structure body, all areas are provided with enough wall thickness according to corresponding functions, and a shell with an inverted triangular center is also used as a chip collecting bin; the two ends of the inverted-triangle-shaped shell in the Y-axis direction are provided with hollowed-out frame structure machine bodies, corresponding installation space is reserved for a Y-axis driving assembly, guide rail base bodies with different purposes are designed in the X-axis direction, a Y1-axis turning guide rail base body, a Y2-axis turning tool (tower) library guide rail base body, a milling feeding main base table and a milling crossing beam moving in the X-axis direction are sequentially arranged, and the Y-axis direction and the Y-axis direction of the inverted-triangle-shaped shell are opposite. The upper plane of the beam is a Y3-axis milling guide rail base body, so that the upper plane of the beam, the Y3-axis milling guide rail base body, the Y1-axis turning guide rail base body and the Y2-axis turning tool (tower) library guide rail base body form a three-Y-axis lathe bed structure which is independent in turning and milling and interacts with each other.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to an ultra-precise multifunctional cutting machine tool, more specifically a lathe bed integrated with turning and milling and related functional components. Background technique [0002] The essence of high-end cutting machine tools comes from high precision, high efficiency, high stability, low consumption, and environmental protection. The functional components all show a structural layout with turning as the main function, and milling only serves as an auxiliary function. If turning is arranged in a mirror image, the structural foundation of milling will be weakened, and the two form a primary and secondary invisibly. In fact, the bed structure only bears the function of turning. In addition, the center of mass of the bed is mainly rectangular or trapezoidal. The purpose is to facilitate the storage and drainage of chips and other mixtures. The structure of such a bed s...

Problems solved by technology

The structure of such a bed still has several deficiencies. First of all, although the name is a combination of turning and milling, the essence is turning. Milling is only for turning. Once there is no need for milling in the cutting task, the so-called milling function will be Another defect is that although the main body and center of mass of the bed can improve the compressive strength, bending tensile strength, elastic modulus, thermal expansion rate, stress-deformation coefficient, etc. through the optimization of material and casting process, but There are still certain hidden dangers of shape change, especially the large-format bed structure, which may become one of the important causes affecting the accuracy and stability of the turn-milling compound cutting machine tool. Another shortcoming is the rectangular or trapezoidal structure. The chip pool cannot be discharged by non-mechanical (such as vacuum diversion) methods, and mechanical chip removal technology is used without exception, so it is difficult to meet the conditions of green cutting and the needs of social development
