Hydraulic gear grinding clamp and work method thereof

Abstract

The invention discloses a hydraulic gear grinding clamp and a work method thereof. The hydraulic gear grinding clamp comprises a body with a middle hole. A pull rod is arranged in the middle hole of the body. The two ends of the pull rod both extend out of the middle hole. An upper gland is fixed to the top end of the pull rod. A frustum structure is arranged on the top of the body. A supporting base is fixed to the bottom of a frustum and provided with an expansion sleeve. An expansion sleeve standard piece is arranged outside the expansion sleeve. A sliding piston is arranged at the bottom of the body. The pull rod is connected with the sliding piston. A base is arranged at the bottom of the body. The base is provided with a plurality of springs making contact with the sliding piston. Clamp switching can be finished each time only by replacing the expansion sleeve, the pull rod, the supporting base and the upper gland every time, and sheet tooth type components with the hole diameter of 35 mm-120 mm are compatible. The clamp has the function of automatic feeding and discharging. The clamp not only has the automatic clamping function and but also has the automatic loosening function. Using is simple and convenient, and work efficiency is improved.

Description

【Technical field】 [0001] The invention belongs to the field of tooth parts, and in particular relates to a hydraulic gear grinding fixture and a working method thereof. 【Background technique】 [0002] Grinding gear parts generally require high precision (up to GB6 level or higher). Apart from the error caused by the thermal deformation of the parts themselves, fixtures are one of the main reasons that affect the grinding accuracy. At present, most advanced technologies in the world use static pressure grinding fixtures. The technical threshold of this kind of fixtures is relatively high. Although the precision of the fixtures is high, the expansion range of the sleeve is very small. The clamping force for large parts is insufficient, and the gap between the fixtures The versatility is poor, fast switching cannot be implemented, and the price is expensive. Domestic manufacturers adopt mechanical manual clamping, which is generally achieved by tightening bolts. The accuracy o...

At present, most advanced technologies in the world use static pressure grinding fixtures. The technical threshold of this kind of fixtures is relatively high. Although the precision of the fixtures is high, the expansion range of the sleeve is very small. The clamping force for large parts is insufficient, and the gap between the fixtures Poor versatility, unable to implement fast switching, and expensive

Domestic manufacturers adopt mechanical manual clamping, which is generally achieved by tightening bolts. The accuracy of this kind of clamp is generally not guaranteed, and the clamping force varies according to the habits of the operator. The most important thing is It can no longer meet the needs of automation
