Combined drilling and milling machine tool with simple guide rail

Abstract

The invention belongs to the technical field of a machine tool and especially relates to a combined drilling and milling machine tool provided with a simple guide rail and used for producing rollers. The combined drilling and milling machine tool comprises a machine body, a clamping and positioning mechanism, a drilling and milling machine head, a control panel, and a simple guide rail, wherein the upper plane of the machine body is provided with two parallel tracks on which two sets of hydraulic sliding tables are mounted in a sliding way, each set of the hydraulic sliding tables is respectively provided with a drilling and milling machine head, and the clamping and positioning mechanism is fixed to two sides of the machine body and the tail end thereof. The combined drilling and milling machine tool has the advantages of simple structure, easy operation and low cost, multiple holes can be drilled and milled through once clamping, and the guide rail is composed of a front rail and a side rail both which are mutually vertical and connected by a fastener, thus the machine tool is convenient to process and effectively overcomes the disadvantages of great processing difficulty, high manufacturing cost and low operating efficiency from the sliding guide rail.

Description

technical field [0001] The invention belongs to the technical field of machine tools, in particular to a combined drilling and milling machine tool with a simple guide rail. Background technique [0002] Machine tools are generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc., but parts with high precision and fine surface roughness requirements generally need to be processed in the machine tool. The cutting method is used for final processing. The machine tool plays an important role in the construction of the modernization of the national economy. The disc is the mechanical device used to clamp the workpiece on the machine tool. A machine tool accessory that clamps and positions the workpiece by the radial movement of the movable jaws evenly distributed on...

Problems solved by technology

[0005] Most of the machine tool chucks for clamping workpieces on the main shaft of existing mechanical or numerically controlled processing machine tools use traditional bevel gear transmission three-jaw centering chucks, which have the following disadvantages: the mechanism is complicated, and there are three sets of bevel gear mechanisms in the chuck; Larger axial dimension affects the design range of the machine tool; larger radial dimension results in smaller chuck maximum diameter parameters

[0008] The slider in the machine tool ensures the up and down reciprocating movement of the slider from the upper dead center to the lower dead center through the set guide rail. The guide rail of the existing machine tool slider is fixed on the machine tool body by fasteners in a T-shaped The guide rail and one side guide rail set on the fuselage form a groove-shaped slideway. The slider guide rail with this structure is difficult to process, high in manufacturing cost, and low in work efficiency. Existing metal drilling and milling machines can only drill on the workpiece at one time. Milling a hole, if you need to drill and mill multiple holes, you need to perform multiple clamping and processing, which increases the workload and reduces the processing efficiency. There are also some production organizations that can improve the drilling and milling machine tools at the same time. Many holes are drilled, but most of them are manually operated, with high labor intensity, low production efficiency, high unit cost, and the quality of the produced products cannot be guaranteed
