The invention discloses a special fixed punching device for an aluminum alloy wheel hub of an automobile, which comprises a fixed bottom plate, and support columns are fixedly arranged at both ends of the bottom of the fixed bottom plate, and anti-slip sleeves are fixedly arranged at the lower end of the support column. It relates to the field of hub processing equipment. This special fixed punching device for aluminum alloy wheels of automobiles solves the problems caused by the looseness of the wheels during the existing punching process by placing the wheels to be processed on the lower end of the anti-skid bar and fixing them with the wheel hub fixing device. In the drilling process, the hydraulic telescopic rod stretches up and down to drive the punching device to punch holes, and the fixed spring is used for buffering, which is convenient for fast punching, which solves the problem that the existing punching device takes a long time to work. Low work efficiency, high labor intensity of staff and other problems, the wheel hub that meets the requirements is produced, and the structural design is simple and practical.

Provided is a full-automatic puncture needle developing enhancing method based on pattern recognition. The method comprises the following steps that an ultrasonic probe scans a part to be detected in a vertical mode, and a first ultrasonic image is formed; a puncture needle conducts puncture on the part to be detected at any angle; a puncture angle A of the puncture needle is recognized in a pattern recognition mode; a mainframe controls delay of an array element sound beam of the ultrasonic probe to enable the array element sound beam of the ultrasonic probe to deflect from the vertical direction at a deflection angle B and scan back and forth nearby; a second ultrasonic image taking the puncture needle as the principal thing is formed; a complete ultrasonic image is composited by the first ultrasonic image and the second ultrasonic image. The puncture needle is inserted at any angle, the puncture angle of the puncture needle is automatically obtained through the pattern recognition, the deflection angle B does not need to be preset, and puncture needle developing enhancement is achieved in a full-automatic mode; the deflection angle B of the array element sound beam is calculated out according to the puncture angle A, and deflection does not exist, so that the clearer second ultrasonic image is formed, and the whole puncturing and scanning work is more simple and convenient.
