Problems solved by technology

[0003] However, the spindles of multi-spindle equipment are densely arranged, and the installation space of the belt-type spindle is difficult; therefore, a direct-connected spindle is required for installation. In addition, the impact of the traditional knife-cutting oil cylinder on the spindle bearing will shorten the life of the spindle bearing.
[0004] When the spindle unit is installed, the front end is generally fixed by a flange, and the rear end is a transition fit. Due to the manufacturing accuracy, this transition fit is often difficult to control. If the interference is large, the spindle bearing will be under pressure, and the bearing is easy to heat and damage, and the gap is large. The main shaft is suspended in the air, and the rigidity is poor

Abstract

The invention relates to a direction connection type machining central main shaft unit, and a rigid connection structure of the direction connection type machining central main shaft unit and a main shaft seat. The direction connection type machining central main shaft unit mainly includes a main shaft core, a main shaft sleeve, a main shaft bearing, a tool switching cylinder, a pressure spring, a tool pulling device, and a tool pulling rod. The direction connection type machining central main shaft unit can avoid impact on a main shaft bearing, is simple in structure, and is easy to produce. The invention further discloses a connection structure of the main shaft unit and the main shaft seat.

Description

technical field [0001] The invention relates to a spindle unit of a machining center, especially a direct-coupled spindle unit of a machining center; the invention also relates to a rigid connection structure between the spindle unit and a spindle base. Background technique [0002] With the revitalization and development of the national equipment manufacturing industry, CNC machine tools, as the mainstream product of the machine tool industry, have become the key equipment to realize the modernization of the equipment manufacturing industry. With the personalized, modular and fast-changing market requirements, the demand for high-efficiency, high-reliability, and versatile CNC machine tools is also increasing, and the demand for multi-spindle equipment is becoming more and more vigorous; [0003] However, the spindles of multi-spindle equipment are densely arranged, and the installation space of the belt-type spindle is difficult; therefore, a direct-coupled spindle is requ...
