Abstract

The invention discloses a telescopic tool for machining a large-diameter inner hole by a numerical control lathe, and belongs to the field of mechanical machining devices. The telescopic tool comprises a tool bit (1) and a front tool apron (2) and is characterized by further comprising a rectangular rear tool apron (3), an adjusting nut (4), an adjusting rod (5), a joint bearing (8) and an adjusting seat (9), a large boss and a small boss are formed at the right end of the front tool apron (2), a through hole of the rear tool apron and a through hole in the large boss of the front tool apron (2) are mounted in a matched manner through a pin (6), an outer circle of the joint bearing (8) is fixed at the right end of the rear tool apron (3), an inner circle of the joint bearing is fixed with the adjusting nut (4), the right end of the adjusting rod (5) is connected with the adjusting nut (4), the left end of the adjusting rod (5) is fixed on the adjusting seat (9), and a through hole of the adjusting seat (9) and a through hole in the small boss of the front tool apron (2) are mounted in a matched manner through the pin (6). According to the telescopic tool, the tool bit can expand and contract in the hole diameter of a machining part, so that parts with narrow port sizes and large hole sizes are machined.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to a retractable tool used for machining large-diameter inner holes of a numerically controlled lathe. Background technique [0002] There are many kinds of processing equipment in mechanical processing, and the processing types are different. The cutting tool in CNC lathe processing is the core tool in the processing process. In some special processing fields, only other types of machine tools or special tools and cutting tools can meet the relevant processing technical requirements. In the process of machining the inner hole of the CNC lathe, it is generally difficult to process some parts with a narrow hole size and a larger hole size with a CNC lathe. Sometimes the inner hole knife cannot enter the hole or damage the hole, so it limits Application of CNC lathes. Contents of the invention [0003] In view of the above-mentioned defects of the prior a...
