Special device for machining non-circular holes by utilizing common lathe through improvement

Abstract

The invention relates to the technical field of machining, and particularly to a special device for machining non-circular holes by utilizing a common lathe through improvement. The special device ischaracterized in that the main shaft of the lathe serves as the power input part, the rotating speed is adjusted through a speed regulating mechanism of the lathe, the power of the device is from themain shaft of the common lathe, the power and torque are transmitted out through a gear box assembly and a tool holder assembly of the device, three tool bits in the tool holder assembly are driven torotate synchronously, so as to perform cutting machining on workpieces, and non-circular hoes required by parts can be obtained through one-time cutting of cutting tools; and besides, during the cutting machining process, a cooling liquid nozzle of the lathe is connected onto the device through a pipe, so that the machined workpieces and tools can be cooled, and metal filings are taken away. According to the special device for machining non-circular holes by utilizing the common lathe through improvement, the internal non-circular holes in the parts needing to be machined can be obtained by one-time machining, the operative difficulty and labor intensity of workers and the production cost are greatly reduced, and meanwhile the production efficiency and product quality are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a device specially used for processing non-circular holes by using an ordinary lathe through modification. Background technique [0002] Ordinary lathes are equipment in which the workpiece rotates and the tool is fixed for processing. Boring is a machining process that uses the tool to rotate and the workpiece to be fixed, thereby boring the workpiece. [0003] Existing more commonly used machine tools for machining holes by boring mainly include drilling machines, boring machines and machining centers. [0004] Among them, the drilling machine mainly drives tools such as drill bits or taps by the spindle to perform drilling, reaming, reaming and tapping. The tool clamping method is mainly the friction fit between the inner cone surface of the Morse taper hole of the spindle and the outer cone surface of the tool Morse taper. For the processing of non-circular ho...
