The utility model discloses a multi-color paint coating surface flattening processing structure which comprises a supporting frame, a driving mechanism is installed in the supporting frame, a polishing mechanism is arranged below the driving mechanism and comprises a fixing base, symmetrical air cylinders are installed on the bottom face of the fixing base, and the air cylinders are arranged on the bottom face of the fixing base. And pressure sensors are installed at the output ends of the two air cylinders correspondingly, fixing plates are fixedly connected to the bottom faces of the two pressure sensors correspondingly, buffer springs arranged at equal intervals are fixedly connected to the bottom faces of the two fixing plates correspondingly, and dampers are fixedly connected to the bottom faces of the two fixing plates correspondingly. According to the multi-color paint coating surface flattening device, through cooperation of a buffer spring and a damper, a polished object can be buffered, excessive polishing of the object is avoided, through cooperation of a polishing motor, a coarse polishing head and a fine polishing head, multi-stage polishing treatment can be conducted on the surface of a multi-color paint coating, and the quality of multi-color paint coating surface flattening treatment is improved.

The invention relates to the technical field of hardware polishing, in particular to a multi-face matched precise hardware polishing device which comprises a mechanical arm, a connecting part is installed at the moving end of the mechanical arm, and the connecting part comprises a butt joint column and a shell rotationally arranged on the outer arc face of the butt joint column in a sleeving mode; the output end of the connecting part is in butt joint with an inclined part, and the inclined part comprises a universal joint and a transmission shaft fixedly connected with the bottom of the universal joint; the outer cambered surface of the transmission shaft is rotationally sleeved with a rotary disc, the bottom face of the rotary disc is provided with a plurality of rotationally-connected butt joint frames, the butt joint frames are rotationally connected with the elastic telescopic end of the elastic telescopic rod, and the grinding head can actively incline through an inclined part formed by a universal joint, so that the mechanical arm can grind the area which cannot be touched by a traditional rigid structure; and the application range of the mechanical arm polishing process is greatly expanded, and the problem of'machining dead angles' existing in the industry for a long time is solved.

The invention relates to the technical field of petroleum pipeline machining, and particularly discloses surface treatment equipment for oil pipe machining and a treatment method.The surface treatment equipment comprises a mounting mechanism, a supporting mechanism and two grinding mechanisms, the supporting mechanism is annular, a through hole for a pipeline to penetrate through is formed in the supporting mechanism, and the through hole is provided with a main axis extending front and back; the two polishing mechanisms are distributed on the upper side and the lower side of the main axis. Each polishing mechanism comprises a transmission assembly and an abrasive belt mechanism installed in the transmission assembly. According to the surface treatment equipment for oil pipe machining and the treatment method, the supporting mechanism is arranged on the outer side of the pipeline in a sleeving mode, meanwhile, the upper rotating ring and the lower rotating ring are connected, and the rotating rings drive abrasive cloth to rotate around the outer side of the pipeline through the jacking assembly and the two adjusting assemblies so as to polish welding seams on the pipeline; when the abrasive cloth meets a protruding weld joint in the weld joint polishing process, the polishing force of the abrasive cloth on the weld joint can be increased through the jacking roller, and therefore large polishing force can be accurately applied to the protruding position of the weld joint.
