Novel hobbing cutter holder capable of realizing fast cutter changing on basis of worm wheel and worm rod

Abstract

The invention discloses a novel hobbing cutter holder capable of realizing fast cutter changing on basis of a worm wheel and worm rod. The novel hobbing cutter holder solves the technical problems that when an existing disc type hobbing cutter is dismounted, the operation needs to be completed through the cooperation of multiple persons; the time and the labor are wasted. The novel hobbing cutterholder comprises a box body, wherein a C-shaped block and a hobbing cutter are arranged in the box body; one side of a cuter shaft of the hobbing cutter is clamped into the C-shaped block; a hobbing cutter passage is formed in the other side of the cutter shaft; and a worm wheel and worm rod mechanism is also arranged at the other side of the cutter shaft. Through the arrangement of the worm wheeland worm rod mechanism, only the rotation and movement direction of a worm rod needs to be controlled in the dismounting and jacking process of the hobbing cutter; the automatic implementation is convenient; the speed is higher; the convenience is greater; and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a shield machine and a new hob and tool holder based on worm gears and worms on a TBM that can quickly change tools. Background technique [0002] Full-face tunnel boring machines are widely used in major engineering fields such as transportation, water conservancy, and national defense. However, the degree of automation and intelligence of the full-face roadheader is relatively low, especially the core operation link representing the level of intelligence of the roadheader - the tool change operation is still dominated by manual tool change, when faced with extreme operations such as high pressure, high humidity or corrosion In the environment, there is an international industry problem of "difficult detection and dangerous tool change". It takes up to 4 hours to manually replace a single hob, and the total time spent on tool change accounts for at least one-third of the entir...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the disassembly of the current disc-shaped hob requires the cooperation of multiple people, which is time-consuming and labor-intensive. To provide a new type of hob tool holder based on worm gear and worm gear that can quickly change the tool
