Abstract

The invention provides a spindle structure. A first flange plate is arranged on a worktable base, the first flange plate is sequentially provided with a centering roller bearing, a first spacer, a second space, a first angular contact ball bearing, a third spacer, a fourth spacer and a second angular contact ball bearing, then the first flange plate is pressed with a second flange plate, the second flange plate is fixed to the first flange plate, and then a spindle is installed into the second flange plate; a fifth spacer is arranged on the upper portion of the spindle, then a gear is arranged in the fifth spacer, and a gland is used for pressing the gear and a spindle head; a belt wheel is arranged on the lower portion of the spindle and is pressed through the spacers and a fastening nut. The spindle structure is simple, ingenious, reasonable, uniform and stable in transmission process, low in noise, stable and reliable, and transmission series of the spindle are reduced.

Description

technical field [0001] The invention relates to a spindle structure, which is especially suitable for vertical lathes and belongs to the technical field of mechanical equipment. Background technique [0002] The vertical lathe is mainly used to process large and heavy workpieces with large diameter and short length and workpieces that are not easy to clamp on a horizontal lathe. When the rotary diameter is sufficient, it is difficult to clamp too heavy workpieces on a horizontal lathe. Due to its own weight, it is difficult for processing The accuracy is affected, and the above problems can be solved by using vertical lathe. [0003] In the prior art, the transmission of the main shaft is cumbersome, so it is particularly necessary to optimize the structure of the main shaft. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a main shaft structure, which is simple, ingenious and reasonable...
