Abstract

The invention discloses a rotary table locking mechanism with a feedback function. The rotary table locking mechanism comprises a support frame (1) and a rotary table (2) rotatably supported at the center of the support frame (1), and is characterized in that a friction ring (3) is arranged in the support frame (1), a brake pad (4) in contact with the friction ring (3) is arranged at the bottom of the rotary table (2), a hydraulic piston cavity is arranged in the support frame (1), a piston (5) is movably connected into the hydraulic piston cavity, the brake pad (4) is located between the friction ring (3) and a piston (5), the top of the piston (5) is connected with a connecting plate (6), a trigger connecting rod (7) is movably connected into the support frame (1) in a penetrating mode, the top end of the trigger connecting rod (7) makes contact with the bottom end face of the connecting plate (6), and the bottom end of the trigger connecting rod (7) is hinged to one end of a lever (8).

Description

technical field [0001] The invention relates to a mechanical device, in particular to a turntable locking mechanism with a feedback function. Background technique [0002] When performing automated machining, it is often necessary to allow the workpiece to be processed to rotate in a certain axis direction, and this rotation is generally realized through a turntable. After the turntable drives the workpiece fixed by the fixture to rotate to a suitable angle, the locking mechanism in the turntable acts to limit the degree of freedom in the rotation direction of a certain axis, and the spindle will drive the tool to process the workpiece. If there is a problem or fault in the locking mechanism of the turntable, the turntable will deflect at a certain angle during the processing of the workpiece, which will affect the machining accuracy, and in severe cases, it will also lead to the scrapping of the workpiece and the scrapping of the cutting tool. Therefore need a kind of meth...
