Thin-wall blind hole part honing clamp

Abstract

The invention relates to a thin-wall blind hole part honing clamp. The clamp is used for clamping a thin-wall blind hole part; the thin-wall blind hole part is provided with a compaction part and a hollow part, the honing clamp comprises a supporting frame and a clamp body arranged on the supporting frame, the clamp body is connected to the supporting frame, the clamp body comprises a containing space used for containing a thin-wall blind hole part, a first clamping part which is arranged in the circumferential direction of the containing space, located at the bottom of the containing space and correspondingly collides with the compaction part of the thin-wall blind hole part, and a second clamping part which is arranged in the circumferential direction of the containing space, located above the first clamping part and correspondingly collides with the hollow part of the thin-wall blind hole part, the first clamping part is in rigid contact with the compaction part, and the second clamping part collides with the hollow part flexibly. The thin-wall blind hole part honing clamp has the beneficial effects of being simple in structure, high in clamping speed and safe and reliable in clamping; compared with the traditional clamping technology, the thin-wall blind hole part honing clamp has the beneficial effect that the effect can be improved by three to five times.

Description

technical field [0001] The invention relates to a honing fixture for thin-wall blind hole parts. Background technique [0002] Thin-walled blind hole parts refer to thin-walled mechanical parts with a wall thickness of less than 1.1mm (see figure 1 ). Due to the thin wall and poor rigidity of this type of mechanical parts, it is difficult to clamp them with traditional fixtures. At present, in the prior art, for such thin-walled blind hole parts, the end surface tension clamping method is usually used; as in the Chinese patent CN105290967B discloses a thin-walled circular tube inner hole honing fixture, which includes a fixture body, a left end cover, a right end cover, a driving hydraulic cylinder and a pipeline system. The left end cover and the right end cover are connected to the two ends of the thin-walled round pipe through threads, and the pipeline system is used to inject or discharge hydraulic oil to drive the hydraulic cylinder. Three symmetrically arranged driv...

Problems solved by technology

However, this honing fixture not only has a complex structure and high manufacturing cost, but also has complex operations when clamping workpieces, which is time-consuming, slow clamping speed, and low work efficiency. Thin parts still have the problem of part clamping deformation
