A high-strength and large-table CNC machining center

Abstract

The invention discloses a high-strength and large-workbench numerical control machining center. The structural performance of a base, an upright post, a bed saddle, a workbench and a spindle body are improved, so that power and torsion of a spindle motor driving system are increased; stress backflow analysis between the design span of the bed saddle and the workbench is strengthened, and the size of the workbench and the stroke of an X axis are increased, so that processing conditions are diversified and extended, and the high-strength and high-rigidity mechanical structure of a machine table and the heavy-cutting and high-stability processing conditions are comprehensively enhanced.

Description

technical field [0001] The invention relates to a numerical control machining center. Background technique [0002] With the increasingly fierce market competition, clients constantly put forward new requirements for product quality and functions, and the processing conditions of customer needs are gradually enriched and large-scale and diversified. It has become the trend of enterprise development to improve production efficiency, reduce defect rate, stabilize production operations, shorten processing cycle, meet the large-scale and diversified modularization of processed products, and improve enterprise competitiveness. With the implementation of the occupational safety and health system in enterprises, improving work safety is also one of the goals that enterprises have been pursuing. The medium-sized CNC machining center previously developed by our company still has room to improve the optimal span and application strength of the combination of the workbench and the sad...

AI Technical Summary

Problems solved by technology

As a result, the size and length of the processed workpieces are limited. Under the condition of simultaneous positioning and processing of multiple materials, the structural strength and sliding range are limited, so that the long workpieces cannot be processed normally at one time.

Secondary clamping is still required, which greatly reduces work efficiency; and the positioning accuracy cannot be effectively guaranteed during clamping, so that the machining accuracy after the secondary positioning and the original precision are connected by errors

From the analysis of the protection level of the sheet metal structure of the entire cover, most of the machining centers on the market are integrated with the cover, but they are directly connected to the protection and non-processing areas between the tool magazines, which will seriously affect the working environment after long-term processing

[0003] Disadvantages of the existing technology: the X-axis stroke of the small and medium-sized CNC machining center is short, which cannot meet the processing needs of the client's large-disc and long workpiece

The interchangeability of the tool magazine system is single, and the efficiency of the tool change system is low

The design of medium and light load line rails cannot meet the foundation of heavy cutting, and the long-term service wears a lot, and the maintenance frequency is high

The workbench area is small, which cannot meet the needs of customers for simultaneous positioning and processing of multiple workpieces

There is no detection system for abnormal lubrication in the mechanical lubrication system, and there are certain safety hazards

The outer cover is semi-closed with sheet metal, the cutting connection structure is complicated, it is inconvenient to clean, and there is a safety hazard to the operator
