Problems solved by technology

[0005] In view of the above problems, the present invention provides a super-large CNC vertical mill. By setting a hydraulic mechanism on the processing platform of the traditional CNC vertical mill, the pressure of the hydraulic mechanism is used to drive the main shaft to sink when it is working, and then to drive The working platform is lowered to pre-tighten the various bearings installed on the working platform and the main shaft. When it is not working, the hydraulic mechanism discharges hydraulic oil to release the bearings, which solves the problem that the bearing pre-tightening is not in place during the working process and the working platform floats To solve the technical problems of the working platform, eliminate the floating amount of the working platform, improve the bearing capacity, shock absorption, stability and service life of the working platform

Abstract

The invention provides a super-large numerical control vertical mill machine. The super-large numerical control vertical mill machine comprises a rack, a grinding head mechanism, an adjusting mechanism, a machining platform, a driving mechanism and a hydraulic mechanism. According to the super-large numerical control vertical mill machine, the hydraulic mechanism is arranged on a machining platform of a traditional numerical control vertical mill machine. During operation, the super-large numerical control vertical mill machine drives a spindle to drop through pressure of the hydraulic mechanism and then drives an operating platform to drop to pre-tighten bearings mounted on the operating platform and the spindle. However, during non-operation, the hydraulic mechanism discharges hydraulicoil to release the bearings. The technical problems that the bearings are pre-tightened in place and the operating platform floats up in the operating process are solved. The floating amount of the operating platform is eliminated. The bearing capacity, shock absorption and stability of the operating platform are improved, and the service life of the bearings is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an extra-large numerically controlled vertical mill. Background technique [0002] The rotary table device of the traditional vertical grinding machine is generally composed of workpiece spindle, sleeve, workbench lower seat, workbench and pulley and other parts. The upper end of the workpiece spindle adopts double-row cylindrical roller bearings, the lower end of the spindle is equipped with tapered roller bearings and springs for bearing preload, the periphery of the workpiece spindle is equipped with flat thrust ball roller bearings, and the sleeve and workpiece spindle assembly are fixed in the working position. Put it on the seat under the table, and then fix it on the bed together. The lower end of the workpiece spindle is equipped with a pulley. Because the radial and axial support of this set of devices all adopt rolling bearings, the bearings are easy to ...
