Connecting-rod shaft for automatic planing and sawing machine

Abstract

The invention belongs to the technical field of cutting equipment, and provides a connecting-rod shaft for an automatic planing and sawing machine. By adoption of the connecting-rod shaft for the automatic planing and sawing machine, the problem that an existing connecting-rod shaft for the planing and sawing machine is low in lubricating efficiency coefficient is solved. The connecting-rod shaft for the automatic planing and sawing machine comprises two bearing bushes which are arranged in a butt joint mode, and a first oil groove is formed in at least one joint of the two bearing bushes. A plurality of second oil grooves which are circularly distributed are formed in the inner wall of the connecting-rod shaft. The extension direction of the first oil groove and the extension direction of the second oil grooves are both parallel to the axis direction of the connecting-rod shaft. The second oil grooves are formed in the inner wall of the connecting-rod shaft, and the first oil groove is formed in the joint of the bearing bushes, so that the lubricating area of the connecting-rod shaft is greatly enlarged, the lubrication coefficient of the connecting-rod shaft is increased, the expansion coefficient is decreased, the wastage of parts is reduced accordingly, and the service life of products is prolonged.

Description

technical field [0001] The invention relates to the technical field of cutting equipment, in particular to a connecting rod shaft for an automatic sawing machine. Background technique [0002] Planer saw machine is a kind of mechanical equipment that can realize cutting operations. It is mainly used to cut wooden materials, such as wood squares, planks, etc. Planer saw machine is divided into manual type and automatic type. With the continuous progress of science and technology, Automatic planer saws are gradually becoming mainstream. [0003] The connecting rod shaft is an important part of the saw planer. During work, the connecting rod shaft will move and rub repeatedly, so it is necessary to continuously lubricate the connecting rod shaft. The general structure of the lubrication method in the prior art is relatively Complicated, but when the simple lubrication method is used, the general lubricating oil cannot be evenly distributed on the connecting rod shaft, resultin...

Problems solved by technology

[0003] The connecting rod shaft is an important part of the saw planer. During work, the connecting rod shaft will move and rub repeatedly, so it is necessary to continuously lubricate the connecting rod shaft. The general structure of the lubrication method in the prior art is relatively Complicated, but when the simple lubrication method is used, the general lubricating oil cannot be evenly distributed on the connecting rod shaft, resulting in poor lubrication effect, increasing the consumption of parts and reducing the service life of the product
