Hydraulic clamping device for large ferrule parts

Abstract

The invention discloses a hydraulic clamping device for large ferrule parts. The hydraulic clamping device is characterized in that a supporting moving assembly or a clamping moving assembly acts by rotating an adjusting hand wheel, and other supporting moving assemblies and clamping moving assemblies act together through transition of a bevel gear wheel, therefore, positions of a supporting base and clamping bases are adjusted in the radial direction of a rotating table till the supporting base is adjusted to a target position and the clamping bases are adjusted to the position close to the to-be-clamped side wall of a part, then power is transmitted to a power chuck through a hydraulic cylinder, action of the power chuck is achieved, the power chuck transmits the power to the m clamping bases through pull rods, and the m clamping bases move along first guide rails thererof in the same direction at the same distance so as to clamp the part and ensure that the center of the part is unchanged all the time. According to the hydraulic clamping device, radial positions of the supporting bases and the clamping bases are rapidly and concentrically adjusted according to diameters of ferrule parts;and rapid clamping of the ferrule parts is achieved, and automatic centering of the ferrule parts and the rotating table is achieved.

Description

technical field [0001] The invention relates to the technical field of clamping devices, in particular to a hydraulic clamping device for large ferrule parts. Background technique [0002] Large-scale ferrule parts mainly involve slewing supports of construction machinery, pitch bearings and slant bearings of wind power devices, slewing bearings on shield machines, etc., and have a wide range of applications. The commonly used diameters range from 1000mm to 8000mm, and some diameters have exceeded 12000mm. Tooth-by-tooth scanning quenching and raceway scanning quenching are often required for large ferrule parts, which need to be supported, positioned and clamped on the quenching machine tool. Due to the large diameter and heavy weight of such parts, there will be Radial and end face deformations also require automatic adjustment of the clamping force. It is very important to design a fast, accurate positioning and clamping device that can automatically adjust the clamping ...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the large ferrule parts are usually manually aligned and positioned on the rotary table through the dial indicator, so that the center of the part coincides with the center of rotation, and then manually clamped, the production efficiency is low, the labor intensity of the workers is high, and the positioning and The clamping force cannot be adjusted during processing
