Deep-hole smooth bottle cavity profiling boring cutter

Abstract

The invention discloses a deep-hole smooth bottle cavity profiling boring cutter which comprises a copying motion component, a supporting sleeve component, a resetting component, a cooling system component and a fine adjustment feeding component, wherein the copying motion component is provided with a sliding rod (1); the sliding rod (1) is provided with a copying slot (3); a sliding sleeve (2) sleeves the sliding rod (1); a square hole (7) is formed in the sliding sleeve (2); a cutter head sliding block (4) is arranged in the square hole (7) and can slide along the hole; one end of a sliding pin (5) is mounted on the sliding block (4), and the other end of the sliding pin (5) is provided with a bearing (8); furthermore, the sliding pin (5) and the bearing (8) are arranged in the copying slot (3) after being combined; the sliding pin (5) can slide along the copying slot (3). According to the scheme, the deep-hole smooth bottle cavity profiling boring cutter can machine parts; a running trace of a cutter tip is the bus of a smooth bottle cavity. The cutter can be used on a common lathe, can form a molded cavity trace by one step and has an extremely technical effect.

Description

technical field [0001] The invention relates to a profiling boring tool for a deep-hole smooth bottle cavity, which is mainly used for processing deep-hole smooth bottle cavity, such as the cavity of an aircraft landing gear, and some parts with similar shapes. Background technique [0002] figure 1 Among them, the workpiece 12 is the machining of the cavity of the landing gear of the aircraft. At present, the main method is to process the internal cavity with a flat rotary disc tool, and the flat rotary disc is processed separately at both ends. The flaws are: [0003] 1. The cost of the horizontal rotary disc is very high. 2. The suspension depth of the horizontal rotary disc is limited. When the hole is too deep, the tool will vibrate, and the processing efficiency is very low. 3. The cost of the equipment used is also high, which also causes the processing cost to be too high. Contents of the invention [0004] In order to solve the above problems, the present invent...

AI Technical Summary

Problems solved by technology

[0003] 1. The cost of the flat rotary disc is very high. 2. The hanging depth of the horizontal rotary disc is limited. When the hole is too deep, the tool will vibrate, and the processing efficiency is very low. 3. The cost of the equipment used is also high, which also causes the processing cost to be too high.
