Special fixtures for transmission control device shell lathe and machining method

Abstract

The invention relates to the field of machining, in particular to special fixtures for a transmission control device shell lathe and a machining method. The two fixtures, namely a clamping structure Aand a clamping structure B, are installed on spindles of two SK50P digital controlled lathes separately, both ends of a part are machined separately through two-times clamping, and the requirements of the size of both ends of the part and the coaxiality being 0.05 of both ends are ensured. A flange plate is fixedly connected with machining equipment through fastening screws, so that the part is located at a correct and efficient position, after the part of a control device shell is positioned, a fast clamping mechanism is used for fast clamping of the part; the part is fixed efficiently; after machining is finished, a pressing plate clamping state is opened, and the part of the control device shell can be taken down; and then machining of the other end is completed on another equipment following the same steps.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a special clamp and a processing method for a transmission manipulator casing lathe. Background technique [0002] The shape of the workpiece to be processed is complex, and the end faces and boring holes at both ends of the special-shaped parts are processed as shown, and the coaxiality of the two ends of the holes is required to be 0.05mm. Four-axis flip fixture or horizontal machining center processing. The main defects and deficiencies include: the boring processing equipment in the prior art has high cost, low processing efficiency, high production cost of special tools and tooling, high maintenance cost, complex adjustment of tools and fixtures, poor part positioning, and slow clamping speed , Dimensional instability after processing and other defects, the special jig for boring processing of special-shaped parts in the prior art cannot adapt to mass production, result...
