Disengaging and engaging mechanism for control grip of machine tool

Abstract

A disengaging and engaging mechanism for a control grip of a machine tool comprises a pivoting seat, a shaft core pipe, a movable block, an operation wheel and a control piece. The pivoting seat is combined with the machine tool; the shaft core pipe penetrates through the pivoting seat, an inserting rod is arranged in the shaft core pipe in a penetrating mode, and one end of the inserting rod is exposed out of the shaft core pipe; the shaft core pipe is sleeved with the movable block, and the position, on the periphery of the shaft core pipe, of the movable block is connected with the inserting rod; a positioning block is arranged on one side of the operation wheel, and the operation wheel coaxial with the positioning block is arranged on the shaft core pipe in a pivoted mode; the controlpiece and the end of the inserting rod are combined; the control piece can be pulled to drive the movable block through axial displacement of the inserting rod to move between the first position and the second position, when in the first position, the movable block is disengaged from the positioning block, and when in the second position, the movable block is clamped with the positioning block sothat rotation of the operation wheel can drive the shaft core pipe to rotate, and accordingly the disengaging and engaging mechanism for the control grip of the machine tool is formed.

Description

technical field [0001] The invention relates to a control handle of a processing machine, in particular to a control handle clutch mechanism for a processing machine. Background technique [0002] Known processing machines, such as milling machines or lathes, usually have a processing platform capable of horizontal displacement, which can drive the processing platform to move in at least one axial direction through the shaft in manual mode through the manual rotation of the operating wheel, or can be automatically The actuation of the feeding device makes the processing platform automatically shift between a preset stroke in the automatic feeding mode. [0003] However, the operation wheel is not designed to be detached from the shaft at any time. Therefore, when the automatic tool feeder is activated, the shaft that drives the displacement of the processing platform will also drive the operation wheel to rotate. If the operator does not pay attention and gets too close, the...

[0003] However, the operation wheel is not designed to be detached from the shaft at any time. Therefore, when the automatic tool feeder is activated, the shaft that drives the displacement of the processing platform will also drive the operation wheel to rotate. If the operator does not pay attention and gets too close, the It may be caught by the handle of the rotating operation wheel during processing, causing personal injury; or the handle may knock over adjacent items due to the rotation of the operation wheel, resulting in damage to the item
