Problems solved by technology

The current machining process of the shift fork is: pulling the inner hole-milling the gear-milling the flat part of the shift fork-drilling. Among them, milling the gear, milling the flat part of the shift fork, and drilling are carried out on separate processing equipment. Three times of clamping, three sets of tooling, and three operators, due to multiple clamping, the cumulative positioning tolerance is large, the symmetry, parallelism and position tolerance are difficult to guarantee, and the production efficiency is low and the processing cost is high

Abstract

The invention provides a combined machining device special for a shifting fork. The combined machining device special for the shifting fork comprises a complete lathe body, a hydraulic rotating workbench, two numerical control cross sliding tables, two vertical milling power heads, a boring power head, four hydraulic clamps, an electrical control system, a hydraulic system, a concentrated lubricating device and a cooling and chip removing device. A clamping station is arranged on the front side of the hydraulic rotating workbench; an open gear milling station and a shifting fork flat part milling station are arranged on the corresponding side faces of the two vertical milling power heads fixed to the numerical control cross sliding tables; and a hole drilling station is correspondingly arranged behind the boring power head, and therefore four stations are formed. Four parts can be clamped by the combined machining device special for the shifting fork at a time, the three procedures of milling an opening gear, milling a shifting fork flat part and drilling a hole can be completed through one time of clamping, clamping of the parts is not affected in the machining process, and the deformation quantity of the shifting fork is eliminated through hydraulic pressing; and the machining tact is short, and production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the processing equipment of the components of the transmission control mechanism, in particular to the special combined processing equipment for the shift fork. Background technique [0002] The shift fork is a part of the speed change control mechanism, which is used in automobile gearboxes or other mechanical equipment that needs to change speed. The current machining process of the shift fork is: pulling the inner hole-milling the gear-milling the flat part of the shift fork-drilling. Among them, milling the gear, milling the flat part of the shift fork, and drilling are carried out on separate processing equipment. Three times of clamping, three sets of tooling, and three operators, due to multiple clamping, the cumulative positioning tolerance is large, the symmetry, parallelism and position tolerance are difficult to guarantee, and the production efficiency is low and the processing cost is high.
