Detailed Description

In order to make the object, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments;

in the drawings: a shaft head for a water-cooled roller comprises a stepped shaft head body 1; the spindle nose is characterized in that the spindle nose body 1 is provided with wear-resistant sleeves 2, and the wear-resistant sleeves 2 are distributed at two ends of the spindle nose body; the wear-resistant sleeve 2 is matched with the annular groove 3 on the spindle head body 1, and the outer surface of the wear-resistant sleeve 2 is flush with the outer surface of the spindle head body 1; normal use of the shaft head is ensured; the wear-resistant sleeve 2 is split; the installation and the replacement are convenient; the wear-resistant sleeve 2 is connected and fixed with the shaft head body 1 through the connecting mechanism 7, and the use stability of the shaft head is ensured.

Specifically, the wear-resistant sleeve 2 comprises a semi-ring body a4 and a semi-ring body b5, and a continuous concave-convex structure 6 is arranged on a combined surface of the semi-ring body a4 and the semi-ring body b 5; the hemicycle body a4 is matched and connected with the hemicycle body b5 through a concave-convex structure 6; the connection between the semi-ring body a and the semi-ring body b is tighter, seamless butt joint of the split type wear-resistant sleeve is realized, and a whole is formed. The connecting mechanisms 7 are symmetrically arranged on two sides of the combined surface of the semi-ring body a4 and the semi-ring body b5, so that the phenomenon that the combined surface falls off is prevented, and the structural stability of the wear-resistant sleeve is improved. The connecting mechanism 7 comprises a lock catch 8 penetrating through the wear-resistant sleeve, and a spring 9 is arranged on the lock catch 8; the lock catch 8 is arranged in a T shape; a waist-shaped keyhole 10 matched with the lock catch 8 is arranged on the spindle head body 1, and the tail end of the keyhole 10 is round; the installation and the disassembly are convenient, the trouble and the labor are saved, and the operation is convenient.
