Abstract
The invention discloses an outward expansion type clamp for a bearing ring. The outward expansion type clamp comprises a transition disc connected with a machine-tool main shaft, a chuck base connected with the transition disc, a positioning ring and a clamping jaw, wherein the positioning ring and the clamping jaw are installed on the chuck base. The chuck base is tubular. A clamping jaw installing part where the clamping jaw is installed is arranged on the front side of the chuck base. A fixing shoulder where the positioning ring is installed is formed at the portion, located on the back side of the clamping jaw installing part, of the chuck base. Six slotted grooves are axially formed in the wall face of the front portion of the chuck base at equal intervals. A conical surface with the wide outer portion and the narrow inner portion is formed on the inner circumference of the front end of the chuck base. The outward expansion type clamp further comprises a middle pull rod connected with a piston rod in the middle of the machine-tool main shaft and a front pull rod connected with the middle pull rod. A conical surface matched with the conical surface of the chuck base is formed on the outer wall of the back portion of the front pull rod. After the novel clamp comes into use, the installation speed is two times that of a traditional expansion type spring clamp, and the debugging time is a half of the original debugging time; and in addition, the outer diameter of the clamping jaw can be repeatedly polished, and the service life is several times that of the original clamp.
