A CNC automatic double-end tenoning machine

Abstract

The invention relates to a numerical control automatic double-ended tenoning machine, comprising a base which transversally extends, wherein two processing mechanisms which are glidingly and symmetrically connected onto the base, a processing space is formed between the two processing mechanisms, and each processing mechanism comprises an engine base, a main shaft device, a feeding device, a material clamping mechanism, a material pressing mechanism and a material pushing mechanism. The numerical control automatic double-ended tenoning machine is simple and reasonable in structure, the processing space and the main shaft device are isolated effectively, dusts, sawdust and the like are prevented from entering a main shaft box to influence the normal operation of the main shaft device, the service life of the main shaft device is effectively prolonged, producing and maintaining costs are saved, and the processing precision is high.

Description

technical field [0001] The invention relates to the technical field of a numerically controlled tenoning machine, in particular to a numerically controlled automatic double-end tenoning machine. Background technique [0002] At present, the CNC automatic double-end tenoning machine of the prior art has the following technical defects. 1) The dust-proof technology of the main shaft is not perfect enough, which often causes dust, wood chips, etc. to enter the main shaft assembly, affecting the normal operation of the main shaft assembly, resulting in The service life of the spindle components is shortened, which increases the frequency of component replacement and increases repair and maintenance costs; 2) The feeding device is generally controlled by a servo through the cooperation of a motor, a screw and a guide rail. Although it can be controlled accurately, its structural volume Large, high manufacturing cost, the invention designs a feeding structure that adopts cylinder ...
