High-wall compact high-speed precision vertical machining center

Abstract

Provided is a high-wall compact high-speed precision vertical machining center. The high-wall compact high-speed precision vertical machining center is characterized in that a lathe base is of a box type structure which is composed of three vertical walls and a base plate in a sealing connection mode, an X-direction feeding mechanism is arranged on the top of the rear vertical wall, a Y-direction feeding mechanism is arranged on the top of one side vertical wall, and a Z-direction feeding mechanism is also arranged on the top of the rear vertical wall; the high-wall compact high-speed precision vertical machining center further comprises a B-axis and C-axis double-pendulum workbench which is arranged in the space defined by the lathe base, and is provided with a circular grating; center blind holes are formed in a lead screw of the X-direction feeding mechanism, a lead screw of the Y-direction feeding mechanism and a lead screw of the Z-direction feeding mechanism respectively, steel tubes are arranged in the center blind holes respectively, inner cavities of the steel tubes serve as liquid inlet flow channels, and are communicated with cooling liquid inlets respectively, a liquid turning flow channel is formed by one end of each steel tube and the blind end of the corresponding blind hole, and a liquid outlet flow channel is formed between the outer wall of each steel tube and the inner wall of the corresponding blind hole, and is communicated with a cooling liquid outlet. According to the high-wall compact high-speed precision vertical machining center, the purposes that the lengths of overhanging portions of shafts of a lathe are small, the overall rigidity is good, accuracy is improved, and the speed of rapid movement is increased can be achieved.

Description

technical field [0001] The invention relates to a machining center for machining metal workpieces, in particular to a high-wall compact high-speed precision vertical machining center. Background technique [0002] The main problem of the current vertical machining center is that the structure is old, and all of them are the most primitive so-called "C" layout. The disadvantage of this structure is that the overhang of each axis of the machine tool is large, the overall rigidity is poor, and the accuracy and fast moving speed cannot be effectively obtained. Improvement; the use of this machine tool for mold processing can only meet the needs of general medium and low precision; on the basis of this series of models, it is almost impossible to realize the upgrade and modification of the five-axis linkage of the machine tool. Therefore, such low-tech products have low technical threshold, high penetration rate, similar product technology, fierce market competition, and it is di...

Problems solved by technology

[0002] The main problem of the current vertical machining center is that the structure is old, and all of them are the most primitive so-called "C" layout. The disadvantage of this structure is that the overhang of each axis of the machine tool is large, the overall rigidity is poor, and the accuracy and fast moving speed cannot be effectively obtained. Improvement; using this machine tool for mold processing can only meet the needs of general medium and low precision; on the basis of this series of models, it is almost impossible to realize the upgrade and modification of the five-axis linkage of the machine tool

Therefore, such low-tech products have low technical threshold, high penetration rate, similar product technology, fierce market competition, and it is difficult to talk about profitability and economic benefits.
