Description
Technical field
The invention belongs to hardware & tools technical field, be specifically related to a kind of bolt synchronous Quick disassembling tool.
Background technology
In mechanical field, often the situation of the parts that dismounting is fixed by multiple bolt is simultaneously encountered, typical example is as the engine cylinder cover of car, fixed by one group of bolt and engine cylinder-body, for the cylinder cap of car Santana, by ten bolts, the cylinder cap of car Santana and cylinder body are fixed, no matter be cylinder cap and cylinder body are installed fix, or being unloaded by cylinder cap in cylinder body is all operated one by one bolt by extension bar and the supporting sleeve of assembling-disassembling bolt or driver, one of self-evident shortcoming of this operating type, the operation intensity of operator is large; Two, dismounting efficiency is low.This technical problem had both suffered from automobile production manufacturer for a long time, also suffered from vehicle maintenance industry.
The technical information of bolt synchronous Quick disassembling tool can be seen in disclosed Chinese patent literature, as application for a patent for invention publication No. CN101745883A recommendation has " a kind of multi-bolt dismounting device ", this patent application scheme arranges multiple driven shaft on a limiting plate, the lower end of each driven shaft is configured with the chamber of matching with by the head of the bolt of dismounting, and fix a driven gear on the top of each driven shaft, limiting plate also arranges a driving shaft, driving shaft arranges one handle and a driving gear be meshed with driven gear.When driving shaft being rotated when operator's turning handle, drive driving gear by driving shaft, because driving gear is meshed with the driven gear on all driven shafts, thus drive driven gear by driving gear, finally drive driven shaft by driven gear, driven the bolt needing dismounting by driven shaft.Although this patent application scheme is for specific machinery (dismounting of the head part of plastic extruder), once can to the enlightenment of multiple bolt dismounting simultaneously but objectively give, specifically also can see the 0027 to 0029 section, the description of this patent application.And for example application for a patent for invention publication No. CN103586817A provides " a kind of wheel bolt multi-axial Simultaneous tightening device ", this patent application scheme is that the detachable disk of the multiple hinge axis distributed by surface uniform drives multiple end to be the crank and rocker mechanism of ratchet and sleeve, realize synchronously tightening one group of wheel bolt, specifically can see the 0025th section to 0028 section, the description of this patent.
Although two the patent application schemes being not limited to exemplify above all significantly can alleviate the operation intensity of operator and improve dismounting efficiency to bolt, but because they all use for specific occasion, thus determine this instrument belong to nonstandard product and not there is versatility when using other occasion, and also not there is referentiability in mentality of designing and design concept.Such as when the instrument of the aforesaid one group of cylinder bolt of fast assembling-disassembling will be designed for, can not get the enlightenment of any technology.
In recent years, along with the social recoverable amount of vehicle increases with the speed of blowout, though be Vehicle manufacturers or vehicle maintenance industry all wish a kind of be suitable for disposable to one group of cylinder bolt dismounting and structure is terse, simple operation and be tending towards the bolt synchronous rapid dismounting apparatus of non-maintaining maintenance, for this reason, the applicant has done positive and useful design, finally technical scheme described below is defined, and carried out simulated test taking under secrecy provision, result proves practicable.
