Numerical control drilling, tapping and milling integrated machining equipment with central through hole for water outlet

Abstract

The invention provides numerical control drilling, tapping and milling integrated machining equipment with a central through hole for water outlet, and the equipment is simple in structure and convenient to operate and has a counterweight function. The equipment comprises a rack, wherein an operating table for placing workpieces is arranged on the rack, a water outlet main shaft is arranged on therack in a sliding manner in the Z direction, a main shaft motor for driving the main shaft to rotate is arranged on the rack, and a counterweight block is also arranged on the rack in a sliding manner in the Z direction; the counterweight block is in reverse linkage with the water outlet main shaft; the rack comprises a base and a transverse frame is arranged on the base in a sliding mode in theY direction; the operation table is arranged on the transverse frame in a sliding mode in the X direction; a first driving device used for driving the transverse frame to slide is arranged between thebase and the transverse frame; and a third driving device used for driving the operation table to slide is arranged between the transverse frame and the operation table.

Description

technical field [0001] The invention relates to the field of numerical control processing equipment, in particular to a numerical control drilling, tapping and milling integrated processing equipment with a central through hole for water outlet. Background technique [0002] Machining centers are developed from CNC milling machines. The biggest difference from the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing different-purpose tools on the tool magazine, the machining tool on the spindle can be changed through an automatic tool changer in one clamping to achieve a variety of machining. Function. [0003] The Chinese invention patent with application number 201710983592.7 (application date is 2017.10.20) discloses a machining center mechanism including a base, a column and a spindle head mounted on the column and capable of sliding up and down along the column. The column is installed on the base, an...

Problems solved by technology

[0004] 1. When the shaft head rotates and the workpiece is processed, since the shaft head end and the driving device are located on one side of the column, the center of gravity of the column deviates to the side of the shaft head, resulting in poor stability of the equipment

[0005] 2. Since the center of gravity of the column is biased toward the side of the shaft head, the shaft head will drive the cutter head to rotate the workpiece to produce vibration. The vibration will cause the radial deviation of the cutter head due to the deviation of the center of gravity, resulting in machining errors and affecting the accuracy of the workpiece.
