Multifunctional pop-up knife structure

Abstract

The invention discloses a multifunctional pop-up tool structure, which comprises a tubular tool body shell; a plurality of limiting grooves communicated with the inner cavity of the tool body shell are formed in the front part of the tool body shell; a movable tool head is embedded into each limiting groove; the movable tool heads and the tool body shell are fixedly installed through a first elastic fixation piston ring and a second elastic fixation piston ring; a cutting tool is arranged at the upper part of each movable tool head; the bottom part of each movable tool head is a tool rest substrate; a plurality of chutes are formed in the bottom part of each tool rest substrate; an adjusting mandrel is arranged in the inner cavity of the tool body shell, and moreover, the front end of the adjusting mandrel is connected with a jackstay; the adjusting mandrel is also provided with multiple groups of bosses; the side face of each boss forms a second oblique plane; the second oblique planes are respectively matched with the chutes of the movable tool heads; during a process that the adjusting mandrel is propelled forwards, the second oblique planes of the multiple groups of bosses respectively abut on the chutes of the movable tool heads, so that the front end of each movable tool head is gradually expanded outwards to realize adjustment on the tool processing radius.

Description

technical field [0001] The invention relates to a cutting tool structure, especially one that can be applied to the processing of deep-hole annular grooves of special-shaped parts such as oil grooves, retaining ring grooves and tool relief grooves. It also takes into account the processing of inner holes of ordinary parts, and also has cutting and boring. , grinding and other functions of the multi-functional pop-up cutter. Background technique [0002] When the internal groove of the part is too deep or the rotary structure is relatively complicated, the processing method of using traditional deep hole cutters or lengthening the tool bar with a large-stroke lathe can solve the processing of most parts. However, this traditional method is not only inefficient, but also often limited by the processing length of processing equipment. As far as deep hole tools are concerned, their high cost and harsh equipment requirements are not suitable for single-piece and small-batch produ...

Problems solved by technology

However, this traditional method is not only inefficient, but also often limited by the processing length of processing equipment. As far as deep hole tools are concerned, their high cost and harsh equipment requirements are not suitable for single-piece and small-batch production in the scientific research process. Production; if the machining plan with extended tool holder and large-stroke machine tool is adopted, the turnaround time of parts will be long, the replacement of tools will take a lot of time, and the production efficiency of the enterprise will be low

[0003] In aviation products, some piston rod parts with deep hole grooves or inner holes in the rotary body are often encountered, which cannot be completed by general deep hole processing equipment
