Embodiment Construction

[0018] The large rocker arm processing method of the roller mill of the present invention comprises the following steps:

[0019] The first step is casting blank; rough inspection of appearance and size;

[0020] The second step is the scribing platform, marking and checking the machining allowance lines of the shaft holes on the front and back and the shaft holes on the elevation;

[0021] The third step is self-made end face milling, rough milling the plane of the front shaft hole;

[0022] The fourth step is to stand on the lathe, put on the tooling, turn over the parts and clamp to find the alignment, put on the counterweight, and calculate the position;

[0023] The fifth step, vertical lathe, rough lathe front shaft hole, inspection size, ultrasonic flaw detection of the lower part;

[0024] The sixth step is to vertically lathe, put on the tooling, turn over the parts, clamp and align, and put on the counterweight;

[0025] The seventh step is vertical lathe, the sha...

Abstract

The invention relates to the field of machinery manufacturing and particularly relates to a manufacturing method for roller grinding large scale rocker arm. The method includes the following steps: casting work blank; roughly examining the exterior and the size; marking the platform; marking and inspecting the machining allowance line on the shaft hole on the back and the shaft hole on the facade; self preparing the facing cut, rough milling the surface of the front shaft hole; vertically placing the lathe, loading on the tooling, turning a clamping alignment, putting on the heavy block, calculating the location; vertically placing the lathe, the rough lathe facing the shaft hole, examining the size, flaw detecting the sub component with ultra sound; on the digitally controlled boring miller, loading on the tooling, fine boring facade shaft hole, examining the size. The present invention is simple in operation, convenient to manufacture, and can guarantee the manufacturing quality and manufacturing precision of the work piece, increases production efficiency and lowers production cost.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing method for a large rocker arm of a roller mill. Background technique [0002] The processing of the rocker arm of the roller mill is one of the large-scale key parts that are mainly controlled in production. The roller mill is mainly composed of a rotating grinding disc and a rocker arm system. The key part is the rocker arm system for applying pressure. The rocker arm system is mainly composed of a roller core, It is composed of roller sleeve, grinding roller shaft, bearing, rocker shaft, upper rocker arm and lower rocker arm. Among them, the upper and lower rocker arms are the key parts of the roller mill, and they are also one of the parts with the highest processing technology content in the rocker arm system. The quality of castings, the selection of processing technology routes, the application of new tools, and the optimization of cutting parameters all af...
