Description

Hub motor disc brake disc mounting surface machining device

Technical Field

The invention belongs to the technical field of machinery, and relates to a processing device for an installation surface of a disc brake disc of an in-wheel motor.

Background

The existing disc brake hub motor has high requirements on the shape and position states, and because the accumulated error of the assembled parts such as the disc brake end cover is large, the parts such as the disc brake end cover can not be directly assembled after being processed in place at one time, and before the disc brake is assembled, the disc brake disc mounting surface of the disc brake end cover needs to be processed.

For example, chinese patent literature discloses a special machine for machining a disc brake mounting surface of an electric vehicle hub motor [ application number: 201420218250.8, respectively; authorization notice number: CN203817532U ], which comprises: a base plate; the motor clamping driving device for the processed workpiece consists of five brackets and a first pneumatic component; the third bracket and the fourth bracket are provided with notch grooves for holding the workpiece motor; a first piston rod of a first pneumatic component arranged on the first support penetrates through the second support and can be matched with one end of a main shaft of the workpiece motor; the ejector rod arranged on the fifth bracket can be matched with the other end of the main shaft of the workpiece motor; a cutting tool drive device composed of a sixth bracket and a second pneumatic assembly; the head of a second piston rod of the second pneumatic component is provided with a molding cutter head; driving a first pneumatic assembly to fix a main shaft of a workpiece motor, wherein a shell of the workpiece motor rotates after the workpiece motor is powered on; and the second pneumatic component is driven, so that the molding cutter head can carry out cutting processing on the disc brake mounting surface of the workpiece motor.

The special processing machine with the structure can process the disc brake mounting surface, and the first pneumatic component and the ejector rod are matched with each other to be ejected at two ends of the motor shaft and clamped tightly, so that the motor shaft is overhead and fixed. Under the general condition of a motor shaft, one end of the motor shaft is provided with a shaft hole, while the other end of the motor shaft is not provided with the shaft hole, obviously, the problem of untight clamping exists in a mode that the first pneumatic assembly and the ejector rod are abutted against and clamped, so that the problem that the hub motor deviates from a set position in the machining process is caused, and the machining precision of the mounting surface of the disc brake disc is low; even though all set up the shaft hole at the both ends of axle, lean on the mode of centre gripping through first pneumatic component and ejector pin top, area of contact is little, and the centre gripping area is little, still has the unstable problem of clamp, leads to the problem that the wheel hub motor has skew settlement position in the course of working, leads to the dish of stopping to set up installation face machining precision low.
