Abstract
The invention relates to a socket spanner with an adjustable spacing. Two symmetrical wings of a T-shaped spanner body are provided with inner groove guide rails; sliding blocks are matched with the inner groove guide rails, have the same thicknesses with the inner groove guide rails and are in slide fit with the inner groove guide rails; the sliding blocks are arranged in the inner groove guide rails and can slide along the inner groove guide rails; the centers of the sliding blocks are provided with spline holes; the middle parts of spline inserted pins are matched with the spline holes; screw threads of small heads at the tops of the spline inserted pins are occluded with butterfly nuts; and inserted heads below big round heads at the bottoms of the spline inserted pins are matched with small holes for fastening the end faces of round nuts to be screwed down. The spline inserted pins are inserted into the spline holes; the symmetrical T-shaped spanner body center line is translated along the inner groove guide rails of the two wings, so that the inserted heads are matched and aligned with the hole pitch of the small holes for fastening the end faces of the round nuts to be screwed down; the butterfly nuts are screwed down; and the spline inserted pins are fastened in the corresponding positions in the inner groove guide rails. Due to the adjustable spacing of the spline inserted pins, the socket spanner can adapt to various specifications of hole pitches of the small holes for fastening the end faces of the round nuts to be screwed down and can be used for carrying out installation and disassembly on different specifications of round nut sealing cylindrical parts.
Description
Technical field
The present invention relates to a kind of erecting tools--spanner, particularly a kind of adjustable Socket spanner of spacing of installing sealing round nut.
Background technology
In parts assembling, often encounter and install, as shown in accompanying drawing 8--9 with the cartridge type of round nut sealing: the installation of round nut 11 need be concordant with outer cylinder body 10 or a little less than urceolus 10, and round nut 11 end face is drilled with the hole 12 as tightening up.Existing installing/dismounting method is: the pitch-row subscription specific Socket spanner 13 of the installation aperture 12 be drilled with above according to round nut 11, it is customized that this method belongs to man-to-man specific purpose tool, selected spanner need be followed and be customized according to round nut upper ejector lever pitch of holes, the model of round nut is different, adopt spanner also different, applicability is single; Latch and pull the moment of friction produced when the frictional force relying on interference fit to produce between body overcomes work, it is little to bear moment; Latch and to pull between body owing to adopting interference fit, produces certain plastic deformation, does not use at ordinary times and be also in stress, reduce the service life of instrument.Therefore, existing mounting and dismounting tool is specific purpose tool, poor universality, bears that operational forces is little and life tools are short.
Summary of the invention
The technical problem to be solved in the present invention is to provide the adjustable Socket spanner of a kind of spacing, can carry out effective installing/dismounting by the round nut sealing cartridge type parts different to specification.
For solving the problems of the technologies described above, technical scheme of the present invention is: the Socket spanner that a kind of spacing is adjustable, the T-shaped symmetrical both wings pulling body are provided with inner groovy guide rail, and slide block matches with inner groovy guide rail, thickness is equal and be slidably matched, and slide block loads and can along the slippage of inner groovy guide rail; Its center is provided with splined hole, mates in the middle part of spline latch with splined hole, and the little head thread of spline catch top is engaged with wing nut, and the aperture fastening with the round nut end face needing to be screwed of the plug bottom spline latch under large round end mates.Described T-shaped both wings termination of pulling body is provided with blocking.Described spline latch inserts splined hole, along the inner groovy guide rail of both wings, symmetry is T-shaped pulls the translation of body center line, makes the pitch-row of the plug aperture fastening with the round nut end face needing to be screwed mate contraposition, tighten wing nut, spline latch is fastened on the correspondence position of inner groovy guide rail.
The invention has the beneficial effects as follows: 1, spline latch spacing of the present invention is adjustable, to adapt to the pitch-row of all size of the fastening aperture of round nut end face needing to be screwed, there is generalization, modular characteristic, effective installing/dismounting can be carried out by the round nut sealing cartridge type parts different to specification.
2, adopt rail slide type moving sets, improve stability during adjustment, modified line contact is face contact, can bear larger active force; Latch adopts spline and slide block to fix, and adopts wing nut to compress, does not stress, can compress rapidly again during work when latch does not work, easy to operate.Spline latch is firmly fastening, and stress is good, long service life.Overcome existing man-to-man special spanner, applicability is single, the round nut of different model is needed to the defect of customization and tooling strength deficiency separately.

Detailed description of the invention
embodiment1 as shown in figs. 1-7: the Socket spanner that a kind of spacing is adjustable, and the T-shaped symmetrical both wings pulling body 1 are provided with inner groovy guide rail 6, and slide block 3 matches with inner groovy guide rail 6, thickness is equal and be slidably matched, and slide block 3 loads and can along inner groovy guide rail 6 slippage; Slide block 3 center is provided with splined hole 7, mate with splined hole 7 in the middle part of spline latch 2, the little head thread in spline latch 2 top is engaged with wing nut 4, and the aperture 12 fastening with round nut 11 end face needing to be screwed of the plug 9 bottom spline latch 2 under large round end 8 mates.To screw on after the little head thread of spline latch 2 inserts the splined hole 7 of slide block 3 wing nut 4; The slide block 3 assembling spline latch 2 loads inner groovy guide rail 6, then blocking 5 is loaded T-shaped both wings termination of pulling body 1, and anti-limited slip block 3 deviates from inner groovy guide rail 6.
embodiment 2as shown in figs 1-9: the slide block 3 assembling spline latch 2 described in embodiment 1, can along the inner groovy guide rail 6 of both wings, symmetry is T-shaped pulls the translation of body 1 center line, the pitch-row of plug 9 aperture 12 fastening with round nut 11 end face needing to be screwed is made to mate contraposition, tighten wing nut 4, spline latch 2 is fastened on the correspondence position of inner groovy guide rail 6.Because the spacing of spline latch 2 is adjustable, to adapt to the pitch-row of all size of the fastening aperture 12 of round nut 11 end face needing to be screwed, effective installing/dismounting can be carried out by the round nut sealing cartridge type parts different to specification; Fastening spline latch is firm, and stress is good, long service life.Overcome existing man-to-man special spanner, applicability is single, the round nut of different model is needed to the defect of customization and tooling strength deficiency separately.
The barrel type assembling of round nut, require round nut 11 surface a little less than or concordant with outer cylinder body 10, as Figure 8-9, driving hole when eight apertures 12 in figure are installation, spanner and round nut 11 are exerted a force by latch, overcome the moment of friction between round nut 11 and outer cylinder body 10, round nut 11 is screwed in outer cylinder body 10, formed to close and install.
The present invention adopts rail slide type moving sets, improves stability during adjustment, and modified line contact is face contact, can bear larger active force; Spline latch 2 and slide block 3 are fixed by spline fitted, and adopt wing nut 4 to compress, do not stress when spline latch 2 does not work, can compress rapidly again during work, easy to operate, equipment life is extended.
