Detailed Description

Example one

A clamp for turning a peek bearing bush comprises a main body cylinder 1, wherein the inner diameter of the main body cylinder 1 is consistent with the outer diameter of an arc of the peek bearing bush 4, and a plurality of sliding grooves 8 matched with bumps 4-3 on the peek bearing bush 4 are formed in the height direction of the inner wall of the main body cylinder 1; the peek bearing bush fixing device is characterized by further comprising an upper cover 2 and a lower cover 3, wherein the upper cover 2 and the lower cover 3 are used for fixing a plurality of the peek bearing bushes 4 in the main body cylinder 1, through holes 9 are formed in the upper cover 2 and the lower cover 3, and the diameter of each through hole 9 is larger than the arc diameter of each peek bearing bush 4.

A plurality of the chutes 8 are uniformly distributed on the inner wall of the main body cylinder 1.

The peek bearing bush 4 comprises a metal layer 4-1 and an encapsulating layer 4-2, two ends of the metal layer 4-1 protrude out of the encapsulating layer 4-2, one side faces of the upper cover 2 and the lower cover 3 are provided with flanges 7, and the flanges 7 are matched with the portions, protruding out of the encapsulating layer 4-2, of the metal layer 4-1 and used for enabling the peek bearing bush 4 to be tightly attached to the inner wall of the main body cylinder 1.
