Method for improving machining efficiency of exhaust manifold air inlet flange

Abstract

The invention discloses a method for improving the machining efficiency of an exhaust manifold air inlet flange. The method comprises the following steps that 1, a to-be-machined flange is put at the top of a clamping disc; 2, adjusting rods are rotated in sequence, the tail ends of the adjusting rods enter air outlet channels of clamping plates, the clamping plates are pushed to move in grooves, and then, the to-be-machined flange is fastened; 3, in the flange machining process, a push rod is rotated to push a movable table to move in moving grooves, meanwhile, a threaded rod is loosened, the clamping disc is rotated, and the flange is machined flexibly; 4, in the flange machining process, a draught fan is started, airflow generated by the draught fan enters a fan cover, the airflow in the fan cover is blown into the grooves and the clamping disc, and iron filings generated during flange machining are removed; and 5, after machining of the flange is completed, the adjusting rods are adjusted again, so that the flange is not clamped by the clamping plates and taken down, and another to-be-machined flange is installed. Machining can continue to be conducted without removing the iron filings on the clamping disc.

Description

technical field [0001] The invention relates to a flange processing tool, in particular to a method for improving the processing efficiency of the intake flange of an exhaust manifold. Background technique [0002] The exhaust manifold is connected to the cylinder block of the engine, and gathers the exhaust of each cylinder into the exhaust manifold, with divergent pipelines. The main requirements for it are to minimize exhaust resistance and avoid mutual interference between cylinders. When the exhaust is too concentrated, there will be mutual interference between the cylinders, that is, when a certain cylinder exhausts, it happens to encounter the undischarged exhaust gas from other cylinders. In this way, the resistance of the exhaust will be increased, thereby reducing the output power of the engine. The solution is to separate the exhaust of each cylinder as much as possible, one branch for each cylinder, or one branch for two cylinders, and make each branch as long ...

Problems solved by technology

[0004] At present, when the flange is processed, it is often necessary to fix it with a special fixture for the flange, and then process it. The iron filings generated during the processing of the flange will be scattered around the flange. These iron filings not only affect the flange. The processing accuracy of the flange, and when processing the next flange, it is necessary to clean the iron filings on the fixture before clamping the flange, which reduces the work efficiency. At the same time, because the different parts of the flange are processed, the existing technology The fixed bracket in the frame cannot be rotated and moved, so it is necessary to remove the flange from the fixture and install it in another way, or replace it with another fixture, which will waste a long time, work efficiency is very low, and it is very expensive to use. inconvenient
