Abstract

A linear driving mechanism with a lubrication mechanism comprises a hollow shell, a fixing screw rod and the lubrication mechanism. The fixing screw rod is provided with an external driving thread; a rotating shaft penetrates in the hollow shell; the front side of the shell is provided with a bearing enclosure portion, and a bearing set is arranged between the front side of the rotating shaft and the bearing enclosure portion; a fixing plate with a plurality of fixing holes is arranged at the outer edge of the middle portion of the shell. The lubrication mechanism comprises a liquid inlet passage and a liquid outlet passage, the liquid inlet passage and the liquid outlet passage are formed in the front side and the rear side of the bearing enclosure portion respectively, a first seal ring is arranged between an end cover and a driving shaft, a second seal ring is arranged between the fixing plate and the driving shaft, and the liquid inlet passage and the liquid outlet passage are connected to a lubricant tank. Therefore, lubrication and cooling of the linear driving mechanism are realized, temperature rise is avoided, driving precision is improved, and accordingly machining efficiency is improved.

Description

technical field [0001] The invention relates to a linear drive mechanism with a lubricating mechanism. Background technique [0002] In the cutting process, it is necessary to drive the workpiece or the table to move forward and backward, and for the forward and backward movement, it is necessary to precisely control the distance of the forward and backward movement. Therefore, the precision requirements for the driving mechanism are very high. [0003] In the existing linear drive mechanism, the structure is relatively complicated, the cost is high, and because heat is easily generated during the movement, the positioning accuracy is reduced and the machining accuracy is affected, so it is necessary to improve it. [0004] For this reason, in view of the above-mentioned defects, the designer of the present invention researches and designs a linear drive mechanism with a lubricating mechanism to overcome the above-mentioned defects by concentrating on research and design, an...
