Machining process for machining end face of electric cabinet sensor of new energy automobile

Abstract

The invention discloses a machining process for machining the end face of an electric cabinet sensor of a new energy automobile. The machining process comprises the following steps that a workpiece is put on a clamp and clamped, namely the workpiece is an electric cabinet; the workpiece is overturned by 90 degrees by rotating a rotary table; a cutter does not rotate and directly moves to the position above a machining hole opening of the workpiece, and the cutter deviates by 3 mm in the center X direction; the cutter is deepened to the position 20 mm below the machining hole in the Z-axis direction, in other words, the cutting edge of the cutter is close to the end face of the sensor; the cutter deviates by 3mm in the X direction, so that the center of the cutter and the center of the machining hole are concentric; a cutter spindle starts to rotate, and the rotating speed is increased to 4000 revolutions per minute; the cutter ascends by 5 mm in the Z-axis direction, and the end face of the sensor begins to be machined; after machining is completed, the cutter stops rotating, and then the spindle stops rotating; and the cutter firstly moves by 3 mm in the X-axis direction and then is lifted by 20 mm in the Z-axis direction, the cutter is safely moved out of the machining hole, and machining is completed. When the machining process is used for machining, machining vibration marks are greatly reduced, and the surface roughness of the end face of the sensor is improved.

Description

technical field [0001] The invention relates to the field of new energy vehicle processing, in particular to a processing technology for processing the sensor end face of the electric control box of the new energy vehicle. Background technique [0002] At present, with the rapid development of new energy vehicles, the structure of related new energy vehicle parts is becoming more and more complex. The end face of the sensor in the inner cavity of the electric control box, because of its special processing , the inner surface after passing through the processing hole is the end surface of the sensor, the inner diameter of the end surface of the sensor is larger than 1.5 times the diameter of the sensor hole, and its structure is similar to the reverse T shape), which makes it difficult to process, and the end surface of the sensor is prone to vibration marks, resulting in sensor Installation leaked. Contents of the invention [0003] The purpose of the present invention is...
