Riveting machine and method for cross joints

Abstract

The invention provides a riveting machine and method for cross joints, belongs to the field of universal joint assembly, and particularly relates to the technical field of riveting machines for the cross joints. Unclamping cylinders are arranged on the left side and the right side of the upper end of a bottom plate correspondingly. A positioning block is arranged on the middle portion between the two unclamping cylinders. Fixing blocks are arranged on the left side and the right side of the positioning block correspondingly. A connection rod, a positioning sleeve and a rivet joint are arranged on the fixing block located on the left side, wherein a spring is arranged on the left side of each connection rod and is arranged on one push rod in a sleeving manner, a regulation nut and a locking nut are arranged on the left side of the push rod, and a telescopic spring is arranged on the portion, on the right side of the fixing block on the right side, of the other push rod. A yoke workpiece is clamped on the positioning block. By means of the riveting machine and method, the aims of achieving uniform riveting depths and matching of the cross joints and needle bearing clearance and greatly improving the production efficiency are achieved.

Description

technical field [0001] The invention belongs to the field of universal joint assembly, and specifically relates to the technical field of a ten-byte riveting machine. Background technique [0002] At present, when the universal joint transmission is realized by assembling needle roller bearings at both ends of the ten-byte and ten-byte, in order to prevent the axial movement of the ten-byte and the needle roller bearing after the assembly is completed, the bearing will be disengaged, which will cause the universal joint to be scrapped. , it is necessary to use the method of riveting to axially limit the needle bearing. In order to solve this problem, the riveting head is mainly used for riveting directly. Since the fork workpiece with the ten-point and needle roller bearing is forged, the wall of the fork workpiece is thin, and the opening of the fork workpiece is produced under the high-pressure riveting force. Deformation, resulting in uneven depth of the upper and lower ...

In order to solve this problem, the riveting head is mainly used for riveting directly. Since the fork workpiece with the ten-point and needle roller bearing is forged, the wall of the fork workpiece is thin, and the opening of the fork workpiece is produced under the high-pressure riveting force. deformation, resulting in uneven depth of the upper and lower riveting points
