Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of honing connecting rods, and in particular relates to a small-clearance honing connecting rod device for an anti-slip vertical internal honing machine. Background Art
[0002] At present, the honing connecting rod of the vertical internal honing machine is connected to the main shaft air guide mechanism and the honing head with ball joints at both ends. The connecting rod not only transmits torque, but also transmits the longitudinal push-pull force of reciprocating movement. The ball joints at both ends overcome the coaxiality error between the center of the main shaft and the center of the hole of the workpiece, so that the honing head can move parallel to the center of the workpiece. The connecting rod itself plays the role of a universal joint. However, in this type of connecting rod structure, the ball head and the ball socket in the ball joint are adjusted to a certain gap after being tightened by the nut, and the contact surfaces of both are spherical surfaces. The spherical surface requires higher processing technology to achieve a certain accuracy, and it is not easy to perform fine grinding. It wears faster under reciprocating impact force, and the final result is a short service life of the connecting rod.
[0003] And as the number of uses increases, there is a risk that the cylindrical pin will loosen and fall off, thus affecting the normal use of the equipment. Utility Model Content
