Description
Technical field
The utility model relates to a kind of main equipment maintenance unit, and particularly a kind of decollation bolt takes out structure.
Background technology
Between the parts of main equipment, bolt connects is a kind of conventional connected mode, some main equipments are in running, inevitably produce vibration, and the vibration frequency of different parts and Oscillation Amplitude there are differences, bolt is as the connector of different parts, bear the shearing force that this non synchronous vibration brings, damage is caused to bolt.Therefore, after equipment longtime running, the bolt connected often can produce the situation that distortion is even ruptured.Bolted two parts, as a rule outside parts adopt unthreaded hole, inner side parts to adopt screwed hole, the screw rod of bolt is through fastening with screwed hole after unthreaded hole, and after bolt fracture, normally break at screwed hole position, traditional method, after being dismantled by outside parts, is taken out the decollation bolt in the parts screwed hole of inner side, now decollation bolt section is from screwed hole nose end apart from little, and decollation bolt takes out relatively simple.And for main equipment, single parts not only weight are large, and be usually fixedly connected with basis, bottom surface, dismounting difficulty is large, if take out decollation bolt after the parts of dismounting outside, workload is large, even after ressembling, likely affects assembly precision.Moreover, the oversize reamer bolt that main equipment adopts, usually at more than M16, existing decollation bolt take out instrument usually for be the taking-up of small size bolt, directly in the operation of screw thread nose end, the unthreaded hole be difficult to across outside parts carries out decollation bolt taking-up to the screwed hole of inner side parts.
As the US Patent No. 6761089B2 of bulletin on July 13rd, 2004, disclose a kind of decollation bolt and take out instrument, this device adopts hexagon cylinder, one end of cylinder is drill bit, the other end is tapered thread, first adopt drill bit to punch on bolt section, then adopt tapered thread to snap in the hole accomplished fluently, bolt is taken out.This device, once across the unthreaded hole of outside parts, causes nose end and bolt section distance to increase, be just difficult to position section, and this device uses for small size bolt usually, easily skid when taking out for oversize reamer bolt, cause taking out unsuccessfully.
Summary of the invention
The purpose of this utility model be to solve existing decollation bolt take out instrument be difficult to across the unthreaded hole of outside parts carry out bolt taking-up and when taking out for oversize reamer bolt easy slippage problems, a kind of decollation bolt that can complete across the unthreaded hole taking-up decollation bolt of outside parts is provided to take out structure, for the taking-up for more than M16 decollation bolt.
The utility model solves the technical scheme that its technical problem adopts: a kind of decollation bolt takes out structure, comprise outside parts and inner side parts, outside parts offer unthreaded hole, inner side parts offer screwed hole with unthreaded hole correspondence position, screwed hole is embedded with decollation bolt, lead is provided with in described unthreaded hole, the rear end of lead has the step being fastened on unthreaded hole end face, lead cylinder and unthreaded hole matched in clearance, in the axis both sides of lead, symmetry offers two pilot holes vertically, the section of decollation bolt guide drill bit to offer two spliced eyes by pilot hole, two round steel are each passed through two pilot holes and insert in spliced eye.The section of bolt is originally as irregular, if punched by force across the distance of unthreaded hole section, misoperation can produce skids and is damaged to screw thread, unthreaded hole esd resistance on the parts of outside is power-assisted by this organization plan, the distance of unthreaded hole section is utilized to adopt lead to lead, drill bit is along pilot hole positional punch on bolt section, punch position not easily skids, after having punched, round steel is adopted to insert in the spliced eye accomplished fluently through pilot hole, then turn lead, make round steel distortion thus be stuck in spliced eye, drive decollation bolt to back-out from screwed hole.This structure avoids the trouble of removing outside parts when getting decollation bolt, adopts round steel distortion to drive the form of screws, is applicable to the oversize reamer bolt taking out more than M16, avoids the situation that traditional approach skids when decollation bolt section central punch is taken out.
As preferably, the cross section of described step is regular hexagon.During taking-up, turn lead more easily stressed.
As preferably, described pilot hole diameter is 1/4 ~ 1/3 of bolt diameter.Pilot hole determines the size of spliced eye and the diameter of round steel, ensures that round steel has enough intensity and don't can be corrupted to the screw thread of screwed hole.
As preferably, described lead step place is consistent with the unthreaded hole degree of depth to the length of lead front end.Lead can make as required according to the actual size at each decollation bolt place, to reach better fitness.
As preferably, described bolt diameter is not less than M16.The too small bolt of engineering diameter makes a call to two spliced eyes not easily, and torsion is little, and existing central punch mode can be adopted to take out.
As preferably, described round steel outside dimension is not less than 5mm.Round steel size can not be too small, ensures that in taking-up process, round steel can not be twisted into two parts.
The utility model adopts lead to lead in the unthreaded hole section of outside parts, can not remove outside parts and take out the decollation bolt in the parts screwed hole of inner side; Taking-up structure utilizes pilot hole to be directed at decollation bolt section and bores two spliced eyes, utilize the distortion of round steel to clamp thus drive decollation bolt to turn taking-up, avoiding in the process of turning and skid.

Detailed description of the invention
Also by reference to the accompanying drawings the utility model is further illustrated below by specific embodiment.
Embodiment: a kind of decollation bolt takes out structure, as shown in Figure 1.This structure comprises outside parts 1 and inner side parts 2, and outside parts dismounting difficulty is large.Outside parts offer unthreaded hole 9, inner side parts correspondingly with unthreaded hole 9 offer screwed hole 10, adopt the bolt of M30 to be threaded with screwed hole 10 through unthreaded hole 9 under normal operating conditions to be fixed, in the present embodiment, the leading portion of M30 bolt forms decollation bolt 6 at screwed hole 10 Fracture and is embedded in screwed hole.Taking-up structure as shown in Figure 1, 2, is provided with columniform lead 3 in unthreaded hole 9, lead rear end is hexagonal step 5, and step is stuck in the outer end end face of unthreaded hole, and lead bottom is concordant with unthreaded hole the inner.Lead offers the pilot hole 4 of two diameter 10mm in axis bilateral symmetry, and on the section being directed at decollation bolt 6 by pilot hole 4, correspondence offers two spliced eyes 7.The round steel 8 of diameter 9.5mm inserts in spliced eye 7 through pilot hole 4.
At step 5, place turns lead, makes round steel distortion be clamped on spliced eye place, thus drives decollation bolt to rotate taking-up.
