Abstract

The invention discloses a hydraulic gear grinding clamp. The clamp comprises a clamp body, wherein the clamp body is divided into an upper clamp body and a lower clamp body that are fixedly connected;an elastic sleeve for sleeving and positioning the inner hole of a gear to be machined seals and sleeves around the upper outer wall of the upper clamp body; an upper oil storage cavity for storing hydraulic oil is arranged inside the upper clamp body; an elastic-sleeve tension oil passage that communicates with the upper oil storage cavity and is partially arranged between the outer wall of theupper clamp body and the inner wall of the elastic sleeve is also arranged inside the upper clamp body; and a hydraulic drive structure for pressing the hydraulic oil in the upper oil storage cavity into the elastic-sleeve tension oil passage and further pressing the hydraulic oil into between the outer wall of the upper clamp body and the inner wall of the elastic sleeve is arranged on the lowerclamp body. According to the hydraulic gear grinding clamp, the gear to be machined can be sleeved with the elastic sleeve, and the hydraulic drive structure drives the hydraulic oil in the upper oilstorage cavity to flow into the elastic-sleeve tension oil passage and then press the elastic sleeve, so that the elastic sleeve positions the inner hole of the gear.

Description

technical field [0001] The invention relates to the technical field of gear processing and manufacturing, in particular to a hydraulic gear grinding fixture. Background technique [0002] Grinding is a process of processing cylindrical gears or certain gears (helical gears, bevel gears, etc.) using abrasive tools such as grinding wheels. It is mainly used to eliminate deformation after heat treatment and improve gear accuracy. Gear grinding machine is a metal cutting machine tool for gear finishing. It uses a grinding wheel as a tool to grind the gear tooth surface that has been processed to improve the precision and surface finish of the gear. It is suitable for finishing and quenching with high hardness. Steel gears. When in use, the fixture is used to clamp the part, and the machine tool performs processing according to the set program. [0003] When the existing gears are being grinded, they are usually manually aligned and clamped, that is, the inner hole runout is me...
