A double-sided boring and milling machine based on the principle of fixed axis layering

Abstract

The invention discloses a double-sided boring and milling machine based on a fixed axle layering principle. The double-sided boring and milling machine structurally comprises a feeding ram, a machining platform, boring and milling main axles, upright posts, lifting plates, a main axle motor and a fixed base, wherein the bottom of the feeding ram is mounted on the top of the fixed base in a buckling manner; the upright posts are separately arranged on the left side and the right side of the fixed base; and the front ends of the upright posts are connected with the lifting plates in a buckling manner. According to the double-sided boring and milling machine disclosed by the invention, the machining platforms can be separately ascended and descended through a layering mechanism, so that the situation that the boring and milling main axles can machine the upper end part and the lower end part of a workpiece in a limited range is ensured, the layering mechanism is divided into a main platform and an auxiliary platform and can be independently controlled according to the volume range of the workpiece, and thus, the volume difference between the platform and the workpiece is reduced at maximum, the situation that the boring and milling main axles impact the platform is avoided, and rotation control of the main platform and the auxiliary platform can be carried out through a bidirectional switching group when angles need to be switched, and therefore, a limitation distance is lengthened, the machining range is widened, and the risk of equipment collision strokes can be effectivelyreduced.

Description

technical field [0001] The invention relates to the field of milling machines, in particular to a double-sided boring and milling machine based on the principle of fixed axis layering. Background technique [0002] Milling machine refers to the equipment that mainly uses the milling cutter to process various surfaces on the workpiece. Usually the rotation of the milling cutter is the main movement, and the movement of the workpiece and the milling cutter is the feed movement. The horizontal boring and milling machine is generally a relatively large device, and the horizontal The same principle is true for CNC boring and milling machines and machining centers currently produced. It is just that the boring machine for processing parts is less restricted. The ram of the boring and milling machine is relatively stable and the machining surface accuracy is relatively high. can be realised. There are such problems in the use of existing technologies on the market: [0003] Since...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a double-sided boring and milling machine based on the principle of fixed axis layering to solve the problem that the current processing table can only perform horizontal adjustment processing by moving the ram after the workpiece is fixed. , the height position can only be controlled by the lifting shaft itself, and the platform position cannot be adjusted when processing some workpieces with large height values, which leads to the situation that the lifting shaft is prone to limit, and it is impossible to process the head and tail of the workpiece with a large position difference The problem
