Large-scale flange type workpiece punching positioning device

Abstract

The invention discloses a large-scale flange type workpiece punching positioning device. The device comprises a horizontally arranged worktable; a vertically arranged drilling machine is arranged on the right side of the top surface of the worktable; a vertical positioning plate support is arranged on the left side of the drilling machine; a horizontal positioning plate is arranged in the positioning plate support; a positioning sleeve is arranged at the left part of the positioning plate; a round flange plate support is arranged at the left part of the positioning plate support; a flange plate is arranged at the upper part of the flange plate support; a central positioning pin is arranged at the center of the top surface of the flange plate; a horizontally arranged positioning rod is arranged at a relative position at the top of the flange plate; vertical through holes are formed in both ends of the positioning rod; a plurality of machining holes are uniformly formed in the circumferential direction of the flange plate; and an auxiliary support is arranged at a relative position at the lower part of the flange plate. The device has the beneficial effects of punching holes with accurate positions in the large-scale flange type workpieces and being simple to operate.

Description

technical field [0001] The invention belongs to the technical field of punching and positioning devices, and in particular relates to a punching and positioning device for large flange-type workpieces. Background technique [0002] Under today's manufacturing technology, the number of large drilling machines and milling machines is still relatively small. The workpieces that need to be processed by large drilling machines generally need to be sent to factories with corresponding equipment for processing, and then shipped back after processing. The whole process is time-consuming and laborious. It is easy to cause damage to the workpiece. [0003] If the position of the hole is determined by the positioning marking device, and then the hole is drilled by a small drilling machine, the processing can also be completed without large-scale equipment, but the deviation of the hole is too large, and this method cannot be used for precision parts. [0004] At present, how to ensure...
