Machining method of perpendicularly intersected hole system of speed reducer body

Abstract

The invention discloses a machining method of a perpendicularly intersected hole system of a speed reducer body. Holes A-B on the vertical axis are machined by a vertical numerical control machining center so as to meet the concentric requirement of the holes on the axis, and simultaneously, a section of horizontal hole is bored based on the vertical axis; the horizontal hole is long in length, only a section of horizontal hole is bored to be used as an aligning basis in order to ensure the machining precision so as to avoid a mark error, so that the section of horizontal hole is used as an aligning basis for machining a horizontal hole V. In the same way, a hole V on the horizontal axis is machined by a high-precision numerical control boring and milling machine by not using a mark as an aligning basis but on the aligning basis on which the vertical holes are machined, and the aligning precision is high; and meanwhile, the space laser detection technology and the numerical control machining technology are matched to ensure the form-position precision of the perpendicularly intersected hole system of the body. The fine surface finishing technology and the numerical control simulation technology of a high-precision numerical control machine are applied to select reasonable cutting amount to meet the low roughness requirement of the surface of the perpendicularly intersected hole system of the body. Through the machining method, the amount of adjustment of assembly is greatly reduced, and the assembly precision is improved.

Description

technical field [0001] The invention relates to the processing technology of mechanical vertically intersecting hole systems, in particular to a method for processing vertically intersecting hole systems with high positional accuracy requirements on a reducer body. Background technique [0002] Vertical mill is a kind of equipment used for grinding cement, coal and other industrial raw materials such as construction, chemical industry and ceramics. Series advantages. The vertical mill reducer is the core transmission equipment of the vertical mill system. Due to the extremely harsh working conditions of the reducer, it is required to operate under the condition of continuous shock, vibration and overload, and the service life is required to be more than 15 years, and the reliability requirement is also particularly high. Furthermore, the reducer is located under the vertical mill. Under the condition of meeting the power requirements, the reducer is required to be as small...

Problems solved by technology

[0011] From the above process flow, it can be seen that the processing of vertical intersecting holes is two associated independent processing procedures. The vertical hole A-B is a common lathe process, and the horizontal hole V is a common boring and milling machine process. Low, can not guarantee the shape and position accuracy required by the drawings of the two perpendicularly intersecting holes; and the position accuracy of the vertically intersecting holes in the past cannot be directly measured, only to be adjusted during assembly, the adjustment workload is very large, and it is difficult to meet the assembly accuracy requirements of the drawings
