Description

Lower nut tightens rotation-preventing mechanism on a kind of full-automatic film column pull rod
Technical field
The utility model belongs to lower nut on machinery field more particularly to a kind of full-automatic film column pull rod and tightens anti-favourable turn Structure.
Background technique
Applicant is engaged in sewage treatment industry, and the most crucial component of sewage disposal device is dish tubular membrane column, dish tubular type It is fixed among film column by the nut at pull rod and both ends.But on automatic assembly production line, pull rod and upper and lower ends When the assembly of nut, since nut tightens torque demand and required torque is bigger, when the nut of pull rod upper end passes through Torque spanner assembly will drive pull rod when tightening and lower end nut rotates together with, and is located at the nut of lower end and not up to screws and want It asks, to make this assembly failure.Existing mode is usually by two workers operation simultaneously, and a worker fixes one with spanner Nut, another worker screw another nut, screw requirement to guarantee that upper lower nut all reaches, but in automatic production line this Entire producing line efficiency can be greatly reduced in kind mode；Another practical problem is the nut positioned at lower end, periphery working space It is small, it is inconvenient when going to screw, therefore generally take fixed lower end nut, the mode that screws end nut reaches matching requirements, but by Uncertain in the hexagonal direction supplied materials of lower end nut, the spanner on automatic production line can not accurately engage, it is necessary to by artificial Correction makes hex nut angle be just aligned wrench opening, these operations all bring difficulty to the anti-rotation of lower end nut.
Utility model content
To overcome above-mentioned technological deficiency, the utility model discloses lower nut on a kind of full-automatic film column pull rod and tightens anti-favourable turn Structure, comprising: pedestal, spanner fixing seat, guide post, guide post fixing seat, cylinder, cylinder fixed seat, contour screw, driving plate, spring, Spanner fixed plate, spanner, the spanner fixing seat, guide post fixing seat, cylinder fixed seat are mounted on the base, the guide post installation In guide post fixing seat, cylinder is installed on cylinder fixed seat, and spanner fixing seat both ends open up movable span, by movable span Axle sleeve is mounted on guide post, and spanner is connect by spanner fixed plate with spanner fixing seat front, and the fixed base rear end of spanner installs spiral shell It follows closely, pocketed springs and driving plate on screw, driving plate are connected on Telescopic-cylinder bar.
Further, lower nut tightens rotation-preventing mechanism on a kind of full-automatic film column pull rod of the utility model, and the screw is Two contour screws.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram.
Fig. 2 is the utility model top view.
Specific embodiment
As shown in Figure 1, Figure 2, lower nut tightens rotation-preventing mechanism on a kind of full-automatic film column pull rod of the utility model, including Pedestal 1, spanner fixing seat 2, guide post 3, guide post fixing seat 4, cylinder 5, cylinder fixed seat 6, contour screw 7, driving plate 8, spring 9, spanner fixed plate 10, spanner 11, the spanner fixing seat 2, guide post fixing seat 4, cylinder fixed seat 6 are mounted on pedestal 1, institute It states guide post 3 and is installed on guide post fixing seat 4, cylinder 5 is installed on cylinder fixed seat 6, and 2 both ends of spanner fixing seat open up activity Hole is mounted on guide post 3 by the axle sleeve in movable span, and spanner 11 is connected by spanner fixed plate 10 and 2 front of spanner fixing seat It connects, 2 rear end mounting screw 7 of spanner fixing seat, pocketed springs 9 and driving plate 8 on screw 7, it is flexible that driving plate 8 is connected to cylinder 5 On bar.
Lower nut tightens rotation-preventing mechanism on a kind of full-automatic film column pull rod of the utility model, and the screw 7 is two contour Screw.
The utility model principle and effect:
When assembly parts arrive at assembly position, cylinder 5 pushes driving plate 8 that power is transferred to spanner by spanner fixing seat 2 11, spanner 11 and the lower end nut to be fixed can show two states at this time, and one is lower end hex nut edge directions just It is good consistent with 11 opening direction of spanner, then the hex nut that spanner 11 directly blocks lower end is kept fixed, upper end nut tightening Assembly can be completed；Another situation is that the hex nut edge direction of lower end and wrench opening direction are inconsistent, spanner can not Engage with hex nut edge, then spring 9 is in preloading condition under the thrust of cylinder 5 at this time, but has no effect on upper end at this time Hex nut screws, and film column pull rod and lower end nut will be driven to rotate together during the nut tightening of upper end, instantly end nut When rotation to edge just engages with the opening of spanner 11, the precompression release of spring 9 directly promotes spanner and lower end nut card Merging is kept fixed, and upper end nut is further continued for being torqued-up to matching requirements.
