Problems solved by technology

[0004] At present, gantry milling is used to drill the radial high-pressure oil holes on the inner wall of disc gears. The gears are laid flat, and the right-angled head is replaced separately and inserted into the inner holes of the gears to process radial oil holes one by one. The processing efficiency is low. Prolonged processing time using large processing equipment, resulting in a significant increase in production costs

Abstract

The invention discloses a continuous positioning drilling method for inner wall radial holes, comprising the following steps: preparing processing equipment; hanging parts to be processed on the equipment; making the radial holes to be processed at the lowest point; moving the right side The frame inserts the guide rail of the axial electric guide rail slider structure into the slide rail sleeve; drives the axial electric guide rail slider structure for zeroing operation, and sets the axial processing size parameters; drives the horizontal electric guide rail slider structure on the rotating roller shaft Make sure that the radial hole is vertically pointing to the axis of the inner hole; after driving the vertical electric guide rail slider structure to return to zero, set the processing depth parameters to meet the processing depth of the radial hole; start the equipment to carry out Radial hole processing; after the completion, the drill bit is withdrawn from the radial hole, and the handle is rotated to process the next hole to realize continuous processing without lifting the workpiece; or change to the next workpiece for processing. The method is adopted to ensure the processing quality of the workpiece.

Description

technical field [0001] The invention relates to a positioning drilling method for radial holes, in particular to a continuous positioning drilling method for the inner hole wall of a large disk-shaped gear. Background technique [0002] In power transmission gearboxes for wind turbines, ships, etc., the weight of a single gear is too high and the processing is difficult. Usually, the gear part and the support shaft are processed separately, and the interference connection is used to assemble a gear assembly for production. manufacture. However, with the continuous increase of the power of the gearbox, the selection of the interference amount between the inner hole of the gear and the outer diameter of the support shaft is also gradually increasing, resulting in annealing of the material when the temperature is too high when the shrink sleeve is installed, and annealing occurs when the press is disassembled. Conditions that affect the characteristics of gear parts such as se...
