Machining center mechanism

Abstract

The invention discloses a machining center mechanism. The machining center mechanism comprises a base, a stand column, and a main shaft head mounted on the stand column and capable of sliding up and down along the stand column; the stand column is mounted on the base; the stand column comprises a stand column body, shaft head guide rails, a shaft head collision preventing table, and a shaft head limiting switch connected with the shaft head collision preventing table and used for controlling the main shaft head to stop downwards moving; two shaft head guide rails are arranged on the stand column body, and are arranged in parallel; the shaft head collision preventing table is arranged on the stand column body, and is positioned between the two shaft head guide rails; and the shaft head collision preventing table can butt against the bottom end of the main shaft head. As the machining center mechanism is provided with the shaft head collision preventing table and the shaft head limitingswitch connected with the shaft head collision preventing table, when the main shaft head moves to a limit position at the bottom end, the main shaft head is stopped from downwards moving through theshaft head limiting switch by touching the shaft head collision preventing table, the collision damage condition of the main shaft head is prevented, and the use safety of the machining center mechanism is effectively improved.

Description

technical field [0001] The invention relates to the technical field of machining of mechanical parts, in particular to a machining center mechanism. Background technique [0002] The machining center mechanism includes a base, a saddle, a worktable, a column and a spindle head that can be raised and lowered along the column. The saddle and column are installed on the base, and the workbench is installed on the saddle. The spindle head is used as the spindle system of the machining center. The cantilever The beam form is suspended on one side of the column and must bear a large bending moment. The column includes a column body and a shaft head guide rail. Specifically, the spindle head is slidably connected to the shaft head guide rail, and slides up and down along the shaft head guide rail. [0003] During the downward movement of the spindle head, if no parts to be processed are placed on the workbench, the staff controls the downward movement of the spindle head. If the s...

Problems solved by technology

[0003] During the downward movement of the spindle head, if no parts to be processed are placed on the workbench, the staff controls the downward movement of the spindle head. If the spindle head moves to the bottom of the spindle head guide rail, the staff has not stopped the downward movement of the spindle head. The end of the spindle head may break away from the guide rail of the spindle head, and the spindle head may collide with the worktable or base, which reduces the safety of the machining center mechanism
