A foldable small hole large noodle machine with anti-scraper

Abstract

The invention discloses a foldable small-hole large-face machine plus anti-scraping tool, which includes an end cover, a knife seat, a joint and a knife bar; the knife bar is connected to the main shaft on the machine tool, and the joint is installed on the knife bar. The lower end of the knife seat is movably mounted on the joint, and the upper end of the knife seat is movably mounted on the end cover, and a forming blade is installed on the knife seat, and the knife seat can rotate between the end cover and the joint; when the end cover, the knife When the seat and the joint are connected together in turn, the rotation of the main shaft on the machine tool drives the corresponding rotation of the knife rod, so that the automatic folding and unfolding of the forming blade between the end cover and the joint is realized. The foldable small-hole large-face machine plus anti-scraping tool of the present invention realizes the automatic folding and unfolding function of the tool holder by using the machine tool spindle, cancels the manual loading and unloading process, simplifies the machining process of small-hole large-face structure, releases labor force, and improves Machine efficiency.

Description

technical field [0001] The invention relates to a foldable small hole large noodle machine plus a reverse scraper. Background technique [0002] At present, when the construction machinery industry processes the large surface on the back of the small hole, such as figure 1 As shown, it includes the inner end face 1 and the hole 2, and a large number of white steel cutters are used for back scraping; due to the limitation of the cutting width of the back milling cutter, high-speed back milling cannot be performed. There are also some manufacturers who manufacture extra-large milling cutters to mill the back of the small hole from the side of the hole to solve the problems of low surface quality when using white steel knives on the back of the small hole, the shape and position tolerance cannot be guaranteed, and the sharpening of white steel knives is difficult. However, the tool cost of the extra-large cutter head is expensive, and the number of blades that need to be insta...

AI Technical Summary

Problems solved by technology

[0007] 1) Due to the anti-scraping method of the white steel knife, when the knife rod advances and retreats, the white steel knife needs to be manually loaded and unloaded repeatedly, which makes the process cumbersome

[0008] 2) Due to the manual sharpening of the white steel blade, the sharpening quality is greatly affected by external factors, and the straightness of the blade directly affects the surface roughness quality and flatness of the anti-scratch large surface

At present, the surface roughness of the workpiece processed by white steel knife back scraping should only reach Ra25. In addition, the surface flatness of the workpiece after processing is out of tolerance and has a tapered structure. Both of them cannot meet the accuracy requirements of the design documents.
