Intermittent feeding device used for lathe

Abstract

The invention discloses an intermittent feeding device used for a lathe. The intermittent feeding device solves the problem that in the prior art, a manual operation feeding device is low in efficiency. The intermittent feeding device comprises a machine frame, a hydraulic cylinder arranged on the machine frame, and a push rod arranged on the machine frame, and further comprises a first supporting leg, a second supporting lug, a rotating shaft, a disc and a feeding clamp, wherein the first supporting leg and the second supporting leg are connected with the push rod, the rotating shaft is located between the two supporting legs and connected with the machine frame in a rotating mode, the disc is fixed to the rotating shaft, and the feeding clamp is connected with one end of the rotating shaft. Three pin columns are evenly distributed on the disc. A first driving block is arranged at one end of the first supporting leg. A second driving block is arranged at one end of the second supporting leg. The first supporting leg is hinged to the middle of the first driving block. The second supporting leg is hinged to the middle of the second driving block. A blocking pin used for limiting clockwise rotation of the first driving block is arranged on the first supporting leg. A blocking pin used for limiting anticlockwise rotation of the second driving block is arranged on the second supporting leg. One end of the first driving block can abut against one pin column on the disc. One end of the second driving block can abut against another pin column on the disc. The intermittent feeding device is simple in structure and high in practicability.

Description

Technical field [0001] The invention relates to the technical field of lathe processing, in particular to an intermittent feeding device for a lathe. Background technique [0002] In lathe processing, the feeding device is often required to achieve intermittent feeding due to the tool withdrawal. The intermittent period is the working period of the lathe tool to meet the processing requirements. At present, this type of operation is basically performed by the worker operating the feeding device, and the feeding device is manually performed. Start and stop to achieve intermittent movement; this not only requires workers to accurately judge the length of the processing interval, but also a long-term operation is a test of the physical and mental strength of the workers, and the efficiency is low, and it is easy to fatigue the workers and cause accidents; in addition, this operation Insufficient accuracy and unstable. Summary of the invention [0003] The present invention intends t...
