Automatic Correction System Based on Diesel Engine Connecting Rod Machining Machine Tool

Abstract

The invention relates to an automatic straightening system based on a diesel engine connecting rod processing machine tool, comprising a machine tool body and an automatic straightening device; both sides and the front side of the machine tool body are provided with openings, a worktable is arranged below the opening, and a working table is arranged above the opening. A storage box; the automatic correction device includes a tooling fixture set up and down, a correction line generating device for generating a correction line on the tooling fixture, and a device that drives the tooling fixture and the correction line generating device to move horizontally on the workbench and in the storage box, respectively. A translation frame, a camera for acquiring an image of a fixture, a central controller, the central controller acquires an image of the fixture and extracts the position characteristic values ​​of the connecting rod and the correction line therefrom, and controls the fixture according to the difference of the position characteristic values Correct the link position. The invention utilizes the straightening line generating equipment to project a laser beam on the tooling fixture to form the straightening line, takes the straightening line as the reference line, and cooperates with the intelligent fixture to automatically correct the connecting rod, and has high processing efficiency and high quality.

Description

technical field [0001] The invention belongs to the technical field of diesel engine connecting rod processing, and in particular relates to an automatic correction system based on a diesel engine connecting rod processing machine tool. Background technique [0002] The connecting rod of the diesel engine is used to connect the piston and the crankshaft, and transmit the force on the piston to the crankshaft, converting the reciprocating motion of the piston into the rotational motion of the crankshaft. The connecting rod body consists of three parts, the part connected with the piston pin is called the small end of the connecting rod; the part connected with the crankshaft is called the big end of the connecting rod, and the part connecting the small end and the big end is called the connecting rod body. [0003] When the connecting rod is processed, due to the error in the blank size of the connecting rod, it is necessary to measure the thickness before processing, mill th...

Problems solved by technology

[0003] When machining the connecting rod, due to the error in the size of the connecting rod blank, it is necessary to measure the thickness before machining, mill the upper and lower surfaces, and then open the center of the connecting small end and the large end after completion. Before opening the hole, it is necessary to It is not only inconvenient to do manual operation, but it is also easy to cause errors and affect the processing quality and efficiency.
