Self-limited universal honing rod

Abstract

The invention relates to a self-limited universal honing rod comprising an outer pipe, a honing head, a lower joint, a push rod, a supporting rod and an upper joint, wherein the honing head is connected with one end part of the outer pipe, the lower joint is fixedly connected with the other end of the outer pipe, the push rod is arranged in the outer pipe, the supporting rod is connected with the push rod, and the upper joint is sleeved on the supporting rod; the honing rod further comprises one or more cross-shaped blocks, a connection pipe and a limiting sleeve, wherein the one or more cross-shaped blocks are sleeved on the push rod, the connection pipe is fixedly sleeved out of the one or more cross-shaped blocks, the limiting sleeve is sleeved out of the connection pipe, and the two end parts of the limiting sleeve are respectively connected with the upper joint and the lower joint. According to the self-limited universal honing rod disclosed by the invention, the cross-shaped blocks are sleeved on the push rod, so that the honing rod can realize multidirectional floatation; through a space between the connection pipe and the limiting sleeve, the floating displacement of the honing rod can be controlled within the certain range, so that the self-limiting function of the honing rod is realized, and a complex guiding system can be saved; and the honing rod has the advantages of novel and compact structure, simple manufacturing and low machining cost.

Description

technical field [0001] The invention relates to a tooling facility, in particular to a self-limiting universal honing rod. Background technique [0002] Honing is a process of finishing the finished surface with a honing stick inlaid on the honing head. It mainly processes various cylindrical holes with a diameter of 5-500 mm or even larger, and the ratio of the hole depth to the hole diameter can reach 10. or larger. During honing, the workpiece is installed on the worktable of the honing machine or in the fixture, and the honing rod is inserted into the processed hole, driven by the spindle of the machine tool to rotate and reciprocate axially. During processing, the honing rod needs to have a certain floating amount, but this floating amount should not be too large. In the prior art, it is usually completed by the guiding system on the machine tool, but this guiding system is very complicated and the equipment cost is high.
