Detailed description of the invention
In order to explain enforcement of the present utility model more fully, provide embodiment of the present utility model.These embodiments are only the elaborations to this device, do not limit scope of the present utility model.
Be described further with regard to the technical solution of the utility model referring to Fig. 1 and Fig. 2, in figure, 1: steel pipe, 2: contact block, 3: connecting rod, 4: jointed shaft, 5: resilient contact switch, 6: scraper, 7: scraper fixed axis, 8: lift cylinder, 9: magnetic valve, 10: compressed air hose, 11: feeler lever, 12: nut, 13: tie rod holes, 14: spring, 15: feeler lever end.
The technical solution of the utility model is a kind of pipe crimping weld seam automatic scraper lifting device, Fig. 1 is the structural representation of steel pipe girth seam checkout gear, Fig. 2 is the connection diagram of cutter and lift cylinder, described scraper is fixedly connected on the scraper fixed axis 7 of processing equipment, automatic scraper lifting device comprises steel pipe girth seam checkout gear and scraper lifting device, steel pipe girth seam checkout gear and scraper lifting device are connected with controller respectively, described steel pipe girth seam checkout gear comprises and is arranged on steel pipe 1 two contact blocks 2 circumferentially, selection makes jointed shaft and contact block center not on a vertical line, such two contact blocks are connected on jointed shaft nature contact can be pressed in steel tube surface, two contact block 2 tops are connected to connecting rod 3, connecting rod 3 is provided with jointed shaft 4, other one end of two connecting rods 3 is respectively arranged with feeler lever 11, feeler lever 11 is located in the tie rod holes 13 of interlinking lever end respectively, two feeler levers are oppositely arranged, resilient contact switch 5 is provided with in the middle of two feeler levers, between the feeler lever end 15 of elastic switch 5 side and connecting rod 3 few one or both sides feeler lever on be provided with spring 14, the other end of feeler lever is provided with nut 12 and compresses.Be provided with resilient contact switch 5 in the middle of two feeler lever ends, resilient contact switch 5 is connected with controller.
