Abstract

The invention discloses a multi-process, multi-workpiece and double-station fixture for a rudder shaft, relates to a fixture, and aims to solve the problems that an existing rudder shaft workpiece isstrict in dimensional tolerance requirement, high in surface roughness requirement and high in machining difficulty, and is prone to generate unqualified products, products often need to be repaired,and the machining time is long. At present, no fixture for simultaneously performing multiple procedures of workpieces on three-axis equipment exists. The fixture comprises a fixture body, a first locating hinge pin, a second locating hinge pin, an inner groove plug block, a U-shaped pressing plate, a first pressing plate connecting piece, a step pressing plate and a second pressing plate connecting piece. A first stepped slope and a second stepped slope are sequentially machined on the two side walls of a through groove, and two first hinge pin locating holes are symmetrically machined in thetwo ends of the bottom of the through groove separately; and each rudder shaft slope workpiece to be machined is arranged on the surface of the second stepped slope in the length direction of the fixture body. and a plurality of stepped pressing plates are arranged on each rudder shaft slope workpiece to be machined. The fixture is applied to the field of multi-workpiece machining.

Description

technical field [0001] The invention relates to a fixture, in particular to a rudder shaft multi-process, multi-workpiece, double-station fixture used for multi-workpiece processing. Background technique [0002] At present, the rudder shaft workpiece in the prior art has strict dimensional tolerance requirements, takes a long time for equipment, and requires high surface roughness, which requires repeated turning over of the workpiece. The workpiece has many processes, multiple equipment is used to repeatedly turn over the surface, the surface roughness is high, and the processing is difficult. Using general-purpose flat-nose pliers for clamping, the clamping force is small, the size changes greatly, and unqualified products are prone to occur. The workpiece needs to be processed by three-axis equipment in the process of milling facets, and the process of milling inclined planes needs to be processed by four-axis equipment with flat-nose pliers on both sides. The dimensiona...
