Abstract

The invention discloses a novel expansion sleeve of a gear grinding tool, which comprises an expansion sleeve body, the expansion sleeve body is arranged on the gear grinding tool, the outer side of the expansion sleeve body is sleeved with a gear workpiece, the expansion sleeve body comprises an inner ring and an outer ring, an annular cavity is formed between the inner ring and the outer ring, the cavity is filled with an elastic filler, a pressing block located at the upper end of the elastic filler is movably arranged in the cavity, the upper end of the pressing block extends out of the cavity and makes contact with the gear grinding tool, the pressing block downwards presses the elastic filler, and the elastic filler is pressed to elastically deform so as to push the outer ring to expand the inner ring of the gear workpiece. The gear grinding tool comprises a shell, the shell is provided with a positioning mandrel and a pull rod, and the positioning mandrel is sleeved with the expansion sleeve. By means of the mode, the novel expansion sleeve of the gear grinding tool and the gear grinding tool can ensure that the expansion sleeve effectively expands a workpiece, and are simple in structure, good in using effect, safe and reliable.

Description

technical field [0001] The invention relates to the field of expansion sleeves, in particular to a novel expansion sleeve of a gear grinding tool and the gear grinding tool. Background technique [0002] The process of using a gear grinding machine to grind the teeth of a gear is called gear grinding. Existing gear grinding machines generally use the expansion sleeve of the hydraulic tooling fixture to expand and tighten the gear. The existing expansion sleeve does not have a good expansion effect on the workpiece, and it may cause the gear workpiece to loosen during the gear grinding process. Meet the use requirements. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a new type of expansion sleeve for gear grinding tooling and gear grinding tool, which can ensure that the expansion sleeve can effectively expand and tighten workpieces, and has a simple structure, good use effect, and is safe and reliable.
