Eccentric shaft cutter head device of numerical control plate glass cutting machine

Abstract

The invention discloses an eccentric shaft cutter head device of a numerical control plate glass cutting machine. A multi-area surface contact sliding friction support way is adopted between a cutter head shaft and a shaft sleeve of the cutter head device, so that the rigidity of the cutter head shaft is effectively improved, and the defects that the common cutter head is low in cutting accuracy and short in service life are overcome; furthermore, an eccentric shaft design is adopted by the lower part of the cutter head shaft, so that a cutter wheel of a cutter head is enabled to be maintained to be tangent with a cutting line at any time during cutting movement, and the quality of cutting marks is greatly improved; the upper part of the cutter head shaft is connected with a driving wheel in a way of inserting a special-shaped shaft into the middle of a belt pulley for transmitting torque, so that the connection rigidity is high, and the transmission is stable.

Description

technical field [0001] The invention belongs to the field of flat glass cutting equipment, in particular to an eccentric shaft cutter head device for a flat glass numerical control cutting machine. Background technique [0002] When the CNC glass cutting machine cuts flat glass, the vertical cutter head should cut straight or curved according to the given data. The movement of the cutter head during work includes translation, up and down movement and rotation in the flat glass plane. The rotating shaft of the existing glass cutting rotary cutter head is connected and supported by rolling bearings, which can reduce frictional resistance during rotation. However, because the inner and outer rings of the rolling bearing are in point contact, they are easy to wear and tear. After a period of use, the vertical accuracy of the cutter head axis and the flat glass plane will be reduced due to the cutting force; at the same time, when cutting curves, the deflection of the cutter whe...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an eccentric shaft cutter head device for a flat glass CNC cutting machine. The cutter head shaft and the shaft sleeve of the cutter head device adopt a multi-region surface contact sliding friction support mode, The rigidity of the cutter head shaft is effectively improved, which solves the defects of low cutting precision and short service life of ordinary cutter heads; and the eccentric shaft design is adopted under the cutter head shaft to ensure that the cutter wheel of the cutting head remains in phase with the cutting line when cutting and moving. cutting, greatly improving the quality of cutting tool marks; and the upper part of the cutter head shaft is connected with the drive wheel by inserting a special-shaped shaft into the middle of the pulley to transmit torque, the connection rigidity is large, and the transmission is stable
