Abstract

The invention discloses a rotation thimble which includes a center thimble, a middle bush and an out bush set on the center thimble. The rotation thimble has characteristics that: the rotation thimble is composed of the center thimble, a first bearing, a middle bush, a middle bush anti-dust cover, a second bearing, a first coat, a second coat, a first coat anti-dust cover and a fixing bolt; one end shaft body of the center thimble is equipped with two first bearings, one end of the center thimble and the first bearing are set in a cavity of one end of the middle bush, the shaft body on one end of the middle bush cavity is equipped with the second bearing, the middle bush is set on one end of the first coat, another end of the first coat is equipped with the second coat, one end of the second coat is equipped with a pipe socket. The rotation thimble has advantages that the rotation first coat and the second coat are added on the rotation thimble based on the prior rotation thimble; thesecond coat of the rotation thimble can noose one end of a processing workpiece tightly in process of the rotation thimble closing and tightening a wooden workpiece, then, the center thimble closing and tightening which can not occur workpiece eccentricity and increase the processing workpiece quality.

Description

technical field [0001] The invention relates to a thimble, in particular to a rotary thimble. Background technique [0002] Existing automatic wood lathes use the same rotary thimble as mechanical lathes. Since the workpieces processed by automatic wood lathes are all wood products or bamboo products, especially bamboo products are mostly spliced ​​by multiple pieces, and there are two ends of the workpiece. If it is uneven or there is a difference in hardness due to the relationship between the annual rings of wood products, the center hole is not punched in advance at both ends. Most of the existing rotary thimbles of automatic wood lathes are installed on the pneumatic tailstock, and the work is directly tightened by the cylinder shaft. Jitter, which will cause unsafe factors and affect the quality of the processed workpiece, so the effect is not ideal. Contents of the invention [0003] The technical problem solved by the present invention is to provide a rotary thim...
