One-lathe double-end hole boring machine

Abstract

The invention discloses a one-lathe double-end hole boring machine. The one-lathe double-end hole boring machine comprises a machine frame and further comprises a lathe tailstock, a boring frame shaft, a shaft fixing sleeve, a boring cutter holder, a boring cutter, a clamp, a two-hole boring cutter, a long boring rod and a spindle box which are sequentially arranged on the machine frame from left to right, wherein the shaft fixing sleeve installs the boring frame shaft on the lathe tailstock; the left end of the boring cutter holder is rotationally connected with the right end of the boring cutter shaft; the middle of the boring cutter holder is a drive portion; the boring cutter is connected to the right end of the boring cutter holder; the spindle box is located at the right end of the machine frame; the left end of the spindle box is connected with the long boring rod; the left end of the long boring rod is fixedly connected with the two-hole boring cutter; the clamp can slide along a guide rail on the machine frame; a speed reducer driven by a motor is arranged at the left end of the machine frame and provided with a belt wheel; the belt wheel and the rotary portion of the boring cutter holder are in transmission through a belt. The efficiency is greatly improved, and the space is saved.

Description

technical field [0001] The invention relates to a one-vehicle double-head boring machine for engine block production. Background technique [0002] Engine (Engine) is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is not only applicable to the power generation device, but also refers to the whole machine including the power device (such as: gasoline engine, aero engine). [0003] The cylinder block is the skeleton of the engine and the installation basis of the various mechanisms and systems of the engine. All the main parts and accessories of the engine are installed inside and outside to bear various loads; therefore, the cylinder block must have sufficient strength and rigidity . [00...

AI Technical Summary

Problems solved by technology

[0004] At present, when our factory is producing the engine block, the rough boring of the camshaft hole affects the production. In the past, two machine tools were used to complete the three-hole double-head boring process for the three holes of the cylinder block. The reason is that the boring bar is long and the guide rail of the machine tool The stroke is short. After moving into the new workshop, the arrangement of the assembly line machine tools is limited. The two machine tools take up a lot of space and waste time and resources. Multiple clamping is required, the precision is not high, and the efficiency is low.
