Clamp with large wind turbine gearbox body processed in horizontal type processing center

Abstract

The invention provides a clamp with a large wind turbine gearbox body processed in a horizontal type processing center, capable of ensuring less processing procedures and higher accuracy, wherein fourcompression mechanisms are symmetrically arranged at an interval with two in the front and two at the back; four pressure plates of the compression mechanisms are arranged corresponding supporting parts of four supporting columns on the large wind turbine gearbox body; two initial positioning mechanisms are arranged below the back sides of the pressure plates of the two compression mechanisms arranged in the front respectively; rough positioning pieces of the two initial positioning mechanisms are arranged beyond the lower sides of the back ends of the corresponding pressure plates and correspond to rough positioning holes formed in the supporting parts of the two corresponding supporting columns on the large wind turbine gearbox body; two error compensation mechanisms are arranged belowthe front sides of the pressure plates of the two compression mechanisms arranged at the back respectively; and regulation pieces of the error compensation mechanisms correspond to the supporting parts on the two corresponding supporting columns on the large wind turbine gearbox body.

Description

technical field [0001] The invention relates to a fixture for processing a wind power gear case, in particular to a fixture for processing a large wind power gear case on a horizontal machining center. Background technique [0002] see Figure 1 to Figure 4 As shown, a common large-scale wind power gear box includes a rear box 51 and a middle box 50 assembled front and rear, and a rear box cover 53 assembled on one side of the rear box 51, wherein the rear box 51 is a The front end and one side are open box bodies with openings; the middle parts of the middle box body 50 and the rear box body 51 are respectively provided with a coaxial front bearing hole I52 and a rear bearing hole I'52'52' corresponding to the front and rear. On one side of the box body 50 and corresponding to the rear box cover 53 , there are coaxial front bearing hole II 54 and front bearing hole II 54 ′ that pass through the front and back respectively. Due to the large size and heavy weight of the larg...

AI Technical Summary

Problems solved by technology

The improved large-scale wind power gear box can be processed on the horizontal machining center with fixtures, and it solves the problem that the common large-scale wind power gear box can only be processed on the vertical lathe and the vertical machining center respectively. There are many processes, the processing accuracy is difficult to guarantee, and technical problems such as the handling, disassembly, reassembly, time-consuming and laborious of the middle box body 50, the rear box body 51 and the rear box cover 53
