Embodiment Construction

[0014] The mechanical processing method of flange plate of the present invention is characterized in that, comprises the following steps:

[0015] The first step is to choose a CA6140 horizontal lathe, and use a three-jaw self-centering chuck for clamping. Use an outer circle turning tool to rough turn the end face and outer circle of the workpiece, and then drill, ream, and ream the center hole. , change to clamp the other end of the flange, turn around and rough turn the end face and outer circle of the workpiece;

[0016] The second step is to semi-finish the end face and outer circle of the workpiece, and chamfer it, the chamfer is 1×45°, and then turn around and semi-finish the end face and outer circle of the workpiece, and chamfer, the chamfer is 1×45° ;

[0017] The third step is to cut grooves on the workpiece and finish turning the two sides of the large end of the workpiece to ensure that the surface roughness is R0.8;

[0018] The fourth step is to draw 6 through...

Abstract

The invention relates to the field of flange machining, in particular to a machining method of a flange. Firstly, one end face and one outer circle of a workpiece are roughly turned, after a center hole is drilled, broached and reamed, the other end of the flange is clamped, operation is turned around, and the other end face and the other outer circle of the workpiece are roughly turned; one end face and one outer circle of the workpiece are turned in a semi-finish manner and are chamfered, operation is turned around, and then the other end face and the other outer circle of the workpiece are turned in a semi-finish manner and are chamfered; grooving is performed on the workpiece, and the two side faces of the large end of the workpiece are turned in a finish manner; six through hole contour lines are drawn, and holes are drilled; the outer cylindrical face of the small end of the workpiece is positioned, and the outer cylindrical face of the other side of the workpiece is ground through an M1420A outer cylindrical grinding machine; operation is turned around, the outer cylindrical face of the other small end of the workpiece is positioned, and the outer cylindrical face of the small end of the workpiece is ground through the M1420A outer cylindrical grinding machine; key grooves are slotted though a slotting machine; and after machining ends, flange parts are blued, and then the parts are inspected and put in storage. By means of the machining method of the flange, the machining process is simple, the machining precision of the workpiece can be guaranteed, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of machining, in particular to a machining method of a flange. Background technique [0002] Disc parts are a common mechanical part, which mainly play the role of support and connection in mechanical equipment. Disk parts are mainly composed of end faces, inner holes and outer circles, etc. Usually, the diameter of disk parts is larger than its axial dimension, such as gears, flanges and bearing rings. Disc parts are used to transmit power, change direction or play the role of axial positioning and sealing. In order to strengthen the support, there are often bosses, pits, etc. on the disc parts. In addition, in order to connect with other parts, there are also [0003] There are often structures such as keyways and various holes, and flanges are relatively common in transitional connection parts. The current processing methods for flange processing are cumbersome, and the accuracy often does not meet the requiremen...
