Machine tool clamping mechanical chuck capable of being switched between manual operation and automatic operation

Abstract

The invention discloses a machine tool clamping mechanical chuck capable of being switched between manual operation and automatic operation. The machine tool clamping mechanical chuck comprises a mechanical chuck mechanism and a manual-operation and automatic-operation switching mechanism. The manual-operation and automatic-operation switching mechanism is arranged at one side of the mechanical chuck mechanism. The manual-operation and automatic-operation switching mechanism comprises a switching mechanism support, a double-head air cylinder, a lifting gear shaft, a long-column-shaped gear, adriving gear and a pneumatic motor. The two ends of the double-head air cylinder are fixed to the switching mechanism support. The lifting gear shaft is fixedly connected with a cylinder body of the double-head air cylinder through a connecting support. The long-column-shaped gear is fixed to one end of the lifting gear shaft. The driving gear is engaged with the long-column-shaped gear, arrangedon the pneumatic motor and driven by the pneumatic motor. The mechanical chuck mechanism is connected with the manual-operation and automatic-operation switching mechanism and driven by the manual-operation and automatic-operation switching mechanism. By means of the machine tool clamping mechanical chuck, automatic clamping and electronic control are achieved; and meanwhile, the clamping force can be controlled.

Description

technical field [0001] The invention relates to a clamping mechanical chuck, in particular to a switchable manual and automatic clamping mechanical chuck for machine tools. Background technique [0002] Existing chucks can be divided into mechanical chucks, pneumatic chucks and hydraulic chucks according to the driving structure. [0003] Such as image 3 As shown, the mechanical chuck in the prior art generally includes a main body bracket, a spiral turntable, a bevel gear, an inner hexagonal wrench, and jaws. , the bevel gear meshes with the bevel teeth on the edge of the spiral turntable, and the hexagonal wrench is fixed with the bevel gear and rotated on the side of the main body bracket. [0004] The mechanical chuck is generally manually clamped, the wrench drives the threaded disc to rotate, the driving jaws are screwed forward on the threaded disc, and the clamping force is controlled by the operator. Both the pneumatic chuck and the hydraulic chuck are stressed b...

Problems solved by technology

[0005] However, the mechanical chuck is inefficient and relies on manpower

Pneumatic chucks and hydraulic chucks can realize automatic control, but in special cases, human intervention is more troublesome, and it is difficult to realize jogging
