Cutter quick change device for heavy roller lathe

Abstract

The invention discloses a cutter quick change device for a heavy roller lathe, which comprises a cutting tool apron, a cutting board and a cutter blade, wherein, the cutter blade is fixedly arranged at one end of the tool apron in a detachable manner; an inclined mounting surface and a horizontal positioning surface are formed at one end of the cutting board of a cutting tool; an inclined plane matched with the mounting surface of the cutting board of the cutting tool; the other end of the tool apron sticks into the mounting surface and the positioning surface of the cutting board of the cutting tool; the tool apron is stopped in the circumferential direction relatively to the cutting board of the cutting tool; a stud is fixedly arranged at the other end of the tool apron; a pull rod is arranged in the cutting board of the cutting tool, is stopped in the axial direction, and can rotate in the circumferential direction; a threaded hole is formed at one end of the pull rod; the threaded hole formed at one end of the pull rod is in bolted connection with the stud arranged at the other end of the tool apron; a pull rod driving device is also provided; and the pull rod driving device can drive the pull rod to rotate. The cutter quick change device has the advantages that the structure is connected stably and reliably and is assembled and dissembled quickly with less effort. The cutter quick change device reduces the auxiliary time for changing a cutter, and improves the processing efficiency of a machine tool.

Description

technical field [0001] The invention relates to an auxiliary mechanism of a heavy-duty roll lathe, in particular to a tool quick change device for a heavy-duty roll lathe. Background technique [0002] In the field of traditional heavy-duty metal cutting machine tool clamping devices, the clamping method of heavy-duty cutting tools is mostly manual. Generally, more than three clamping bolts are used to clamp heavy-duty cutting tools, which has high labor intensity and low efficiency. Applied to new CNC heavy-duty metal cutting machine tools, it cannot meet the development and requirements of high-efficiency processing and some new products. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a tool quick change device for a heavy roll lathe. The tool quick change device for a heavy roll lathe has fast tool change and stable and reliable tool connection. [0004] The technical solution adopted by the present inv...
