Log drilling supporting mechanism and log drilling device

Abstract

The invention relates to a log drilling supporting mechanism, and belongs to the technical field of log processing equipment. The log drilling supporting mechanism comprises a rack, wherein a rotating assembly and a rotating driving assembly are arranged on the rack; the rotating assembly is used for bearing logs; and the rotating driving assembly drives the rotating assembly to drive the logs to rotate. The invention further discloses a log drilling device. The log drilling device comprises a drilling assembly and the log drilling supporting mechanism, wherein the drilling assembly is slidably mounted on the rack and comprises a drill bit. In a log drilling process, the drill bit is not easy to deviate; the circumstance that the drill bit is jammed is avoided; and the drilling precision is high, the drill bit does not deviate, the drilled logs are high in strength and good in quality, and the drilling processing defective rate is low.

Description

technical field [0001] The invention relates to a log drilling support mechanism, and also relates to a log drilling equipment, which belongs to the technical field of log processing equipment. Background technique [0002] There are many log support columns in wooden structure buildings. Logs contain high moisture content. The moisture content of untreated logs is generally 60%-90%. The moisture content varies according to different factors such as wood species and origin. Due to its low strength and low corrosion resistance, the dried wood cannot be directly used as a support column, and the log needs to be dried. There is a large amount of moisture in the log. During the drying process of the log, the moisture on the outer surface of the log is first released and shrinks inward, while the moisture content in the center of the log is still relatively high, resulting in inconsistent shrinkage of the wood material on the inside and outside of the log. The central part of th...

Problems solved by technology

In the actual processing process, it is found that this drilling process is very unsuitable for logs, because the length of the logs is very long, so the length of the drill bit also needs to be very long to drill through the logs. Rotation, coupled with the gravity of the drill bit, is easy to make the drill bit deviate, and because of the difference in the growth of the log, the center line of the log is not correct, and the wood grain texture of the log is different, resulting in a difference in density. Therefore, in the process of drilling the drill bit, the drill bit is very It is prone to deflection, which will cause the center line of rotation to change. Once the drill bit deflects, the machining center line will become more and more deviated, which may cause the drill bit to freeze and cannot continue drilling, and may even make the drill bit break. The drilling is barely completed. Due to the offset of the center line of the through hole, it has a great impact on the strength of the log column of the subsequent finished product and cannot be used.
