Embodiment Construction

[0010] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0011] The number of revolutions of the spindle of the lathe and the forward and reverse control. Usually, a pulse generator is installed at the end of the main shaft to transmit the revolution information to the computer system. When processing threads and lead screws, the configured spindle pulse generator is installed coaxially, and the connection of the transmission chain is flexible. At the same time, since the spindle generator is an optical component, care should be taken during installation, and the speed should meet the requirements to avoid scrapping. Therefore, it is generally installed when processing threads, and disconnected when not in use to prolong its life.

[0012] CNC machine tools must have a precise transmission system in order to have good precision and surface quality. Considering the shortest feed tr...

Abstract

The invention relates to the mechanical field, especially a new numerical machine tool, comprising a main shaft box, a knife body, a knife shelf, a control stage and a tail bracket; the main shaft is connected to the pulse device and a transmission chain; the stepping electric motor is connected to the guide screw of the feeding movement by the motor retarder; the transverse and vertical feeding system uses the rolling ball screw transmission; the tail bracket uses the controllable electronic tail bracket. The invention has a novel structure, security and reliability and simple technique compared to the current technique, which is suitable for the less quantity, high precision, complicated shapes and short producing period requirement with a stable operating quality controlled by the computer and great operating ability, precisely calculating the movement quality of the coordinate axis; the precision of the operating accessories is significantly enhanced; the size dispersion is little, which makes the assembly easy without the maintenance and assembly.

Description

[technical field] [0001] The invention relates to the mechanical field, in particular to a novel numerically controlled machine tool. [Background technique] [0002] The CNC machine tools on the market now have problems such as low rigidity, poor vibration resistance, large sliding friction resistance, and gaps in transmission components. Parts, but the failure rate is still high, it is difficult to meet the overhaul acceptance standard with traditional repair solutions, and the cost is high. [Content of the invention] [0003] The present invention provides a new type of numerically controlled machine tool in order to meet the requirement of stable and reliable machine tool and low failure rate operation. [0004] In order to achieve the above purpose, a new type of CNC machine tool is designed, including the spindle box of the main shaft, the bed, the control box and the tailstock. The output end of the motor is connected with a reducer, and the horizontal and vertical...
