Description
Technical field the utility model relates in the steel pipe manufacturing industry, weld seam and the body of heavy caliber straight weld steel pipe, spiral weld steel pipe detected, probe wear-resistant block in the continuous defect-detecting equipment of used automated ultrasonic carries out a kind of special-purpose cambered surface grinder of curved face processing.
Probe wear-resistant block in the continuous defect-detecting equipment of background technology automated ultrasonic is to protect ultrasonic probe not to be worn, and plays again a vitals of control coupled water film thickness simultaneously.At present, it all is manual that the cambered surface of domestic probe wear-resistant block is ground, and is to be attached to steel tube surface with emery cloth, the hand hold transducer wear-resistant block blank on emery cloth repeatedly friction finish.The weakness that manually-operated is ground has: 1, hand lapping is so that wear-resistant block blank path repeatability of reciprocating friction on emery cloth is poor, the physical dimension error of wear-resistant block cambered surface is large after the processing, coupled water film thickness poor controllability when causing popping one's head in work, detection sensitivity is unstable during flaw detection.2, because stock removal is large, and the time is long, and hand lapping can only select the relatively poor material of wearability to do wear-resistant block blank, usually uses nylon, very easily wearing and tearing are not durable.3, the probe wear-resistant block of processing generally speaking a nylon material is wanted 15-25 minute, for the occasion of using the channel ultrasonic wave inspection, needs tens probes of processing wear-resistant block, and efficient is low, and labour intensity is large.
Above-mentioned many disadvantages that summary of the invention exists for solving hand lapping probe wear-resistant block cambered surface, the purpose of this utility model is to realize that mechanization is to the grinding of probe wear-resistant block cambered surface, to improve the precision of grinding, improve probe detection sensitivity stability, realize simultaneously with high-wearing feature material manufacturing probe wear-resistant block, to improve the abrasion resistance of probe wear-resistant block.Design of the present utility model is: will have the arenaceous shell housing reach of belt sander now, making an axle that twines the abrasive band shift out workbench fully retightens, and install the guide plate of fixing a flute profile additional on the right side of workbench, length direction along guide plate in the middle of guide plate has a horizontal guide groove, above guide plate, be screwed and be with graduated scale, on guide plate, also be fixed with swing mechanism and the deck part that is connected with swing mechanism, its swing mechanism is: the positioning shaft sleeve that passes guide groove passes through back-up ring, locking nut is fixed on the guide plate, the locating shaft that in positioning shaft sleeve, is provided with, spacing by circlip, two forks pass by the location axle head with two indent semicircles and fork pressing plate inboard on the circular hole that consists of of two indent semicircles that are complementary with it in, be fixed on the locating shaft by housing screw, at the positioning shaft sleeve cover scale pointer arranged; Deck partly is: two fork front ends in the swing mechanism are connected with an end of deck frame by screw thread, axle annular or square or the rectangle deck is inserted in the circular hole on the deck frame other end, is locked by the deck lock-screw, the lifting handle is connected with the axle inner hole thread of deck, on deck with the lock-screw of static probe wear-resistant block blank part.
The utility model cambered surface grinder is to design for processing high-wearing feature, small curve probe wear-resistant block specially, its enforcement, realized the mechanization that the probe wear-resistant block cambered surface in the continuous defect-detecting equipment of automated ultrasonic is ground, the manual operations large labour intensity frees from heavy manual labor, grinding efficiency is high, and the probe wear-resistant block that grinds stainless steel only uses 1-1.5 minute/only; The physical dimension error of the probe wear-resistant block cambered surface after the processing is little, and grinding precision is high, and coupled water film thickness controllability is good when causing popping one's head in work, and detection sensitivity is stable during flaw detection; Can adopt high abrasion resisting material to do the probe wear-resistant block, make the selection of probe wear-resistant block unrestricted, improve the wearability of wear-resistant block, also improve detection efficiency simultaneously.
