Zero-point rapid positioning reference clamp of cylinder cover machining tool

Abstract

The invention relates to the technical field of cylinder cover machining, in particular to a zero-point rapid positioning reference clamp of a cylinder cover machining tool. The zero-point rapid positioning reference clamp comprises an upper end clamping disc, a lower end clamping disc, a positioning connector arranged on the upper end clamping disc and a locking piece arranged at the top end of the lower end clamping disc, and the upper end clamping disc and the lower end clamping disc are oppositely arranged; and the positioning connector movably penetrates through the upper end clamping disc and extends into the locking piece, and the upper end clamping disc and the lower end clamping disc are in butt joint and drive the locking piece to lock the zero point position of the positioning connector. Compared with an air pressure or hydraulic pressure manner, the zero-point rapid positioning reference clamp is not easily influenced by the size of a pressure source, multi-directional zero-point positioning of the positioning connector is completed in the installation process of all parts of the clamp, the repeated positioning precision is only influenced by structural factors of all parts of the clamp, and the precision reliability is high.

Description

Technical field [0001] The present invention belongs to the technical field processing head, in particular to a cylinder head positioning reference machining tooling fixture zero quickly. Background technique [0002] Diesel engine is the heart of the ship, while the diesel engine cylinder head as an important part of the diesel engine, it will affect the performance of the light reduction in the mechanical efficiency of the diesel engine, in serious cases can cause alive Sierra cylinder, Calatrava, even undermine the entire diesel engine, resulting in irreparable loss, so the cylinder head manufacturing process put forward higher requirements, must develop reasonable processing program and technology is very important in order to ensure the quality stability and raise the capacity; [0003] Cylinder head for frequent replacement processing tooling, equipment utilization is low OEE data can consider each process head tooling positioning joint body interface adds design, common mo...

Problems solved by technology

[0004] However, in the prior art, the zero-point rapid positioning reference fixture generally adopts air pressure or hydraulic pressure, and the repeated positioning accuracy is easily affected by the pressure source, and the structure of the air circuit or oil circuit must strictly abide by the operation steps of disconnecting the circuit first and then disassembling the fixture, otherwise it will be easy There are security issues such as equipment damage, which is not conducive to use;
