Special machine tool for inner hole boring of ultralong large-diameter cylinders

Abstract

The invention relates to a special machine tool for inner hole boring of ultralong large-diameter cylinders. Stands are arranged on the left and right sides of a fixed platform; the top of the stand on the left side is fixedly connected with one end of a boring rod through a fastening bolt; the top of the end of the boring rod is fixedly connected with a boring rod cantilever fixing device; the boring rod cantilever fixing device is in threaded connection with a fixed frame pull rod on one side of the stand on the left side through a lever nut; a guide rail is arranged on the boring rod in theleft-right axle direction; the guide rail is slidingly connected with a cutter head module; the cutter head module is connected with a quick-slow cutter feeding mechanism; a cylinder sleeves the boring rod; the cylinder is clamped through a positioning support wheel set; a transmission device for rotating the cylinder is arranged at the end part of the right side of the cylinder; and the transmission device is positioned at the top of the stand on the right side. The special machine tool can meet the machining requirements of cylinders with large diameters, long lengths and high weights, andhas the characteristics of high stability in the machining process and convenience to load and unload the cylinders.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a special machine tool for boring an inner hole of a cylinder with a super long diameter. Background technique [0002] In the mechanical equipment processing industry, when the inner hole of the cylindrical body needs to be bored, the traditional processing technology is to clamp the cylindrical body on the working platform, keep the cylindrical body stationary, install a boring tool on the boring bar of the boring machine, and the boring tool rotates And axial feed for processing. Another process is to process on a special deep hole boring machine. One end of the cylinder is clamped by a chuck, and the other end is positioned by a supporting wheel. The cylinder rotates, the boring bar moves back and forth, and the cutter head (non-rotating) is installed on the bottom of the boring bar. The front end is used for boring and processing the inner hole. The product...

Problems solved by technology

This patent is applicable to a slender high-speed roller with a length of up to 8 meters. It is characterized by high speed. The chuck of the original conventional horizontal lathe is used to clamp the cylinder body. When loading and unloading the body, it is necessary to put the boring bar into the barrel first, and then lift the whole body to the machine tool for clamping. Similarly, after processing, the barrel and the boring bar need to be dropped as a whole, and each time it needs to be re-clamped and found. Positive leveling

[0004] Therefore, the above-mentioned patents are not suitable for processing cylinders with large diameters, long lengths, and heavy weights. In order to solve the above problems, the applicant proposes a special machine tool for boring inner holes of cylinders with super long diameters.
