Milling lathe bed device for double-clamping and fixing long shaft pipe workpieces

Abstract

The invention discloses a milling lathe bed device for double-clamping and fixing long shaft pipe workpieces. The milling lathe bed device for double-clamping and fixing the long shaft pipe workpiecescomprises a lathe bed, wherein the lathe bed is fixedly connected with guide rails; sliding blocks are clamped onto the guide rails in a matching way and are fixedly connected with an upper body seat; the upper body seat is connected with a power assembly through a driving seat; a clamping assembly is fixedly connected to a lathe bed end far away from a servo motor of a power assembly; the lathebed is connected with multiple positioning pipes and a hydraulic cylinder; the hydraulic cylinder is connected with a liquid inlet pipe; the liquid inlet pipe is connected with a hydraulic station; the hydraulic station is connected with an outlet end of a liquid return pipe; the liquid return pipe is connected with the hydraulic cylinder; a piston rod of the hydraulic cylinder is connected with pressing plate shafts; and pressing plates are connected to the upper ends of the pressing plate shafts. According to the milling lathe bed device for double-clamping and fixing the long shaft pipe workpieces provided by the invention, various angle shapes of a circumference can be processed through one-time clamping, and the occurrence of the phenomena of unclamping, scratching and the like causedby accumulated errors produced by secondary clamping, overlong and overweight workpieces, and other problems is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a milling machine bed device for double-clamping and fixing long-axis tube workpieces. Background technique [0002] A milling machine is a machine tool with a wide range of uses. It can process planes (horizontal planes, vertical planes), grooves (key slots, T-shaped slots, dovetail slots, etc.), toothed parts (gears, spline shafts, sprockets), Spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the rotating body and perform cutting work. When the milling machine is working, the workpiece is installed on the worktable or the accessories such as the indexing head. The main movement of the milling cutter is the rotation, supplemented by the feed movement of the worktable or the milling head, and the workpiece can obtain the required processing surface. Due to the multi-blade i...
