Intermittent indexing mechanism for press-assembling of inner ring of knuckle bearing

Abstract

The invention discloses an intermittent indexing mechanism for press-assembling of an inner ring of a knuckle bearing. The intermittent indexing mechanism comprises a turning sleeve, a driving shaft and a cross arm. The bottom of the turning sleeve is fixedly connected with a turnplate. One end of the cross arm is fixedly connected with the upper portion of the driving shaft, and the other end of the cross arm is connected with a punch of a punching machine. Two or more receding grooves are formed in the lower portion of the driving shaft at equal intervals in the circumferential direction, and pawls are connected into the receding grooves through elastic pieces correspondingly. Sliding grooves are formed in the hole wall of an inner hole of the turning sleeve at equal intervals in the circumferential direction, and the number of the sliding grooves is the same as the number of the pawls. Each sliding groove comprises an upper straight groove body and a lower straight groove body, wherein the upper straight groove body and the lower straight groove body are arranged in the axial direction of the inner hole of the turning sleeve, and a boss protruding towards the center of the turning sleeve is arranged between the upper straight groove body and the lower straight groove body. Spiral grooves in the same spiral direction are formed between the lower straight groove bodies and the upper straight groove bodies which are located on one side of the lower straight groove bodies and are adjacent to the lower straight groove bodies. According to the intermittent indexing mechanism for press-assembling of the inner ring of the knuckle bearing, linear movement is converted into intermittent angular rotation, the structure is simple, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a press-fit intermittent indexing mechanism for the inner ring of a joint bearing. Background technique [0002] The assembly method of the existing joint bearing is as follows: the outer ring is placed on an intermittently rotating turntable, and the turntable drives the outer ring to be indexed directly under the punch of the punching machine, and the punch presses the inner ring into the outer ring, and then the turntable rotates again Transfer the press-fitted joint bearing to the next station. The turntable in the above method needs to be driven by hydraulic pressure or an engine to rotate, which has a complicated structure and low manufacturing cost. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the purpose of the present invention is to provide a press-fit intermittent indexing mechanism for the inner ring of the joint bearing, which can drive the turntable to intermittently i...
