A driving and guiding mechanism of a numerical control cutting machine

Abstract

The invention provides technical scheme of a numerical control cutting machine drive guiding mechanism. The mechanism comprises a connecting plate. A supporting plate which is used for fixing a drive mechanism is arranged on the connecting plate. One end of the supporting plate is connected with the connecting plate through a connecting shaft. An adjusting plate is arranged at one end of the supporting plate, wherein the one end of the supporting plate is far away from the connecting shaft. The adjusting plate is fixed with the connecting plate through a pre-tight adjusting screw rod. A spring is arranged on the pre-tight adjusting screw rod. A limiting plate which is used for preventing the supporting plate from shaking is arranged at one end of the connecting plate, wherein the one end of the connecting plate is far away from the connecting shaft. An adjusting cam which is used for clamping tightly the supporting plate is fixed on the limiting plate. The drive guiding mechanism can be effective to eliminate blocking and shaking phenomenon of a support. The drive guiding mechanism is used for guaranteeing cutting accuracy and cutting quality. Degrees of tightness of meshing of racks and pinions also can be adjusted automatically so as to prolong service lives of the racks and the pinions. Furthermore, the drive guiding mechanism is light and handy in structure and convenient to install.

Description

technical field [0001] The invention relates to a driving guide mechanism for a numerical control cutting machine. Background technique [0002] In the prior art, the well-known technology is that the drive guide mechanism support of the CNC cutting machine used now is a cantilever structure, and the lower part of the support is provided with racks and gears to realize the forward or backward movement of the cantilever mechanism. During use, the support is easy Deformation will lead to poor meshing of the rack and pinion, which will reduce the life of the rack and pinion. Moreover, when the support is running at high speed or under heavy load, the support is prone to vibration and gaps will be generated, resulting in poor running stability and reduced machine tool accuracy. There are deficiencies in technology. Contents of the invention [0003] The purpose of the present invention is to provide a technical solution for the driving and guiding mechanism of a numerically ...
