The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of the specific embodiment.It will be appreciated that, mentioned in following embodiment of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the utility model.
Casting core box alignment pin clamp tool structure advantages of simple of the present utility model, by hand-operated jack, be used as power, utilize public stick force arm principle, the jack top power that makes progress is larger, and the folder power of clamp is larger, clamp alignment pin tighter, thereby under jack makes progress the effect of top power, clamping and positioning pin, drives alignment pin upwards to extract, removal efficiency is high, saves maintenance cost.
Detailed description by way of example but unrestriced mode has illustrated the disclosure, should be understood that various aspect of the present disclosure can be by independent realization or the realization of being combined with other aspects below.This description clearly enables those skilled in the art to manufacture and uses us to believe for new and non-obvious improvement, describe some embodiment, alternative, modification, alternative and system applies, comprised the current best mode that is considered to carry out the utility model principle of describing in this description.When describing element or feature and/or embodiment, titled with " one " " one " " be somebody's turn to do " and " described ", be intended to expression and there are one or more in element or feature.Term " comprises " that " comprising " and " having " is intended to is comprising property, and also has extra element or feature beyond being illustrated in those specifically described elements or feature.
As depicted in figs. 1 and 2, this casting core box alignment pin clamp frock is used as power with jack, utilize public stick force arm principle, clamping and positioning pin, and drive alignment pin upwards to extract, its concrete structure comprises: the top power crossbeam 1 and the clamp crossbeam 2 that be arranged in parallel, and the clamp assemblies that is oppositely arranged on top power crossbeam 1 and clamp crossbeam 2 two ends.Wherein, jack lower end as power is supported by jack bearing support 4, and upper end holds out against top power crossbeam 1, thereby drives clamp assemblies to rise, and clamping and positioning pin, drive alignment pin upwards to extract, the efficiency of this casting core box alignment pin clamp frock dismounting alignment pin is high, has avoided existing method often to twist off or break welding position, need welding several times, and alignment pin of every replacing, need scrap a screw, nut, has saved maintenance cost.
Clamp assemblies comprises: clamp 31 and active plate 32, wherein, clamp 31 comprises: two V shaped slabs that opening is oppositely arranged, the lower end of two V shaped slabs forms folder and pulls out the jaw of alignment pin, and has the pincers hook 33 that inside oblique upper extends.The middle part corner of two V shaped slabs is hinged with the two ends of clamp crossbeam 2 respectively, and the upper end of two V shaped slabs is hinged with the lower end of two active plates 32 respectively, and the upper end of two active plates 32 is hinged with the two ends of top power crossbeam 1 respectively.So far, clamp assemblies and top power crossbeam 1, clamp crossbeam 2 form public stick force arm configuration, make jack upwards larger to the top power of top power crossbeam 1, it is larger that the pincers of clamp 31 hook inside folder power, tighter to clamp alignment pin, thereby under jack makes progress the effect of top power, clamping and positioning pin, drive alignment pin upwards to extract, while having guaranteed that jack upwards applies top power to top power crossbeam 1, the pincers of clamp 31 hook not can with the slippage of core box alignment pin.
During use, first, on the both sides that need to change alignment pin 5, with angle abrasive machine, respectively polish a groove, approximately three millimeters deep, eight mm wides.Then, jack bearing support 4 is placed on to the top of alignment pin 5, jack 6 supports by jack bearing support 4, adjusts the height of this casting core box alignment pin clamp frock, make the pincers hook of clamp assemblies clip to alignment pin scarfing groove, jack 6 withstands top power crossbeam 1.Hand-operated jack 6, top power crossbeam 1 by top upwards, drives active plate 32 under jack 6 top power effects, and then, active plate 32 drives again clamp 31, clamps tight core box alignment pin 5.Now utilize public stick force arm principle, hand-operated jack is used as power, when the jack top power that makes progress larger, the folder power of clamp is larger, vise alignment pin tighter, finally in the excelsior top of jack 6 power, and under the pincers power effect of clamp 31, core box alignment pin 5 is extracted from core box 7, just can change new alignment pin, before saving, repeatedly hang and roll up core box, and Rewelding screw etc., originally need within 25 minutes, to change an alignment pin, only need 5 minutes now.
To sum up, this casting core box alignment pin clamp tool structure advantages of simple, is used as power by hand-operated jack, utilizes public stick force arm principle, the jack top power that makes progress is larger, the folder power of clamp is larger, clamps alignment pin tighter, under the effect with the top power that makes progress at jack, clamping and positioning pin, drive alignment pin upwards to extract, removal efficiency is high, saves maintenance cost.
Disclosed is above only several specific embodiment of the present utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
