Abstract
The utility model provides an impact specimen location processing machine for a welding joint, which belongs to the field that a material cutting mode is used to carry out processing operation on metal. The impact specimen location processing machine for the welding joint is composed of a clamp, a CCD camera, a computer, a groove broacher and a milling machine. The clamping of a specimen is firstly completed on the clamp manually, and then is shot by the CCD camera to be converted onto the screen of the computer to be amplified. The position of a notch is determined on the screen by the method of human-computer interaction, and then an electric motor is controlled to drive a cross saddle to cause a longitudinal/transverse driving screw to move to the position of the groove broacher, thereby the specimen is caused to be provided with a V-shaped notch. Then, the longitudinal/transverse driving screw moves to the position of the milling machine to cut the both ends of the specimen to the needed length of a finished product, and the finished specimen is dismounted to complete the whole process flow. By using the utility model, the accurate location that the welding joint impacts the notch of the specimen is realized, the processing step is simplified, the work efficiency is enhanced, the notch position that the welding joint impacts the specimen can be recorded, and the traceability is realized. The utility model is suitable for a research institution which usually carries out a welding joint impact test, and has wide application.
Description
Technical field
The utility model relates to the metal solder manufacture field, more specifically, the utility model relates to a kind of processing unit (plant) of metal welding joints impact specimen, described device is to adopt the photoelectrome chanical integration technology, welding joint impact specimen blank sample position is accurately located, and the device of standard impact specimen is processed in sampling.
