Automatic radial feeding tool rest for end face boring lathe

Abstract

The invention discloses an automatic radial feeding tool rest for an end face boring lathe. The tool rest comprises a toolbar, a tool rest body and a tool bit, wherein the tool rest body is arranged on the toolbar; an automatic radial feeding structure is arranged between the tool rest body and the tool bit, and comprises a screw rod, a sliding seat, and a ratchet mechanism and a gear set, which are arranged on the tool rest body and used for driving the screw rod to rotate; the tool bit is arranged at one end of the sliding seat; the other end of the sliding seat is matched with the screw rod through a nut seat on the sliding seat. According to the tool rest, the tool bit can be automatically and radially fed without manual operation, so that the labor intensity of a worker is reduced, the machining efficiency is improved, and the range of a machining size is widened.

Description

technical field [0001] The invention relates to the technical field of machine tool processing, in particular to a radial automatic feed end face boring tool holder. Background technique [0002] In the mechanical processing industry, it is common to process the internal and external end faces of box and pump body parts, which have high requirements for the verticality and roughness of the end faces, and boring machines are often used to complete the processing. [0003] The traditional boring tool rotates as the main movement, and the movement of the workpiece is the feed movement. When machining end faces of different sizes and specifications, you will choose to replace the corresponding size and specifications of the cutter head. The production efficiency is low, the labor intensity of the workers is high, and the processing range is small. [0004] The tank body, pump body and various shells are mostly composed of welded parts, and the surface, especially the inner surfa...

Problems solved by technology

[0003] The traditional boring tool rotates as the main movement, and the movement of the workpiece is the feed movement. When machining end faces of different sizes and specifications, you will choose to replace the corresponding size and specification of the cutter head. The production efficiency is low, the labor intensity of the workers is high, and the processing range is small.

[0004] The tank body, pump body and various shells are mostly composed of welded parts. The surface, especially the inner surface, has poor flatness. It is prone to overload during processing, and it is easy to damage the tool. The processing stability is poor, which affects the processing accuracy and production efficiency.
