Tear screw dop open
Technical field
The utility model relates to tears filature field automatically open, tears screw dop open in particular to one.
Background technology
What tear screw mouth open is the important component part of tearing filature open.What adopt in the market tears screws appts open after tearing end screw open, and the structure of picking screw mostly is vacsorb or spring structure gripping, moreover direct labor dismantles screw with electric screw driver.Along with industrial expansion and the pursuit for efficiency, the drawback of these methods revealing all gradually:
The mode drawn is larger for the stability dependency of source of the gas, if source of the gas reduces suddenly the phenomenon that will screw caused can not draw, in order to stable source of the gas needs the pressure stabilizing device increasing air accumulator one class, causes equipment cost to increase like this; This kind of method is higher for the required precision of part, and processing technology is complicated, because need to keep air-tightness; The size of suction is wayward, moreover because the structure of screw itself, is very likely stuck on workpiece, cannot draws.
Spring structure be originally the main screw head of card, make it drop, but complex structure not easy-maintaining, part is also not easily processed, and chucking power is also wayward, and being easy to that coping screw is stuck on workpiece cannot successful gripping, and resetting is also poor.
Manual operation efficiency is low, can not meet Production requirement.
Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, provides one to tear screw dop open, reduces requirement on machining accuracy, chucking power is stablized, and fast changeable, do not need complicated disassembly process, only holding screw need be come loose just passable, without the need to readjusting location.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
One tears screw dop open, comprise a pair screw jaw be connected on jaw cylinder two jaw, described screw jaw one end is stiff end, stiff end is fixed on described jaw, the other end is bare terminal end, bare terminal end is for being inverted L shape, and bare terminal end is connected with batch bar axis of guide, and bare terminal end offers to the sections inner side of downward-extension the arc-shaped slot coordinated with the described batch of bar axis of guide.
Further, described jaw cylinder is fixed by cylinder mounting block.
The beneficial effects of the utility model are:
1, chucking power is realized by standard jaw cylinder, ensures stable chucking power.
2, by coordinating with batch bar axis of guide, the inherent characteristic risen after using loosened screw, the section difference of clamping screw terminal and threaded portion realizes the object of gripping, maximized raising reliability.
3, dop is placed in the outside of tearing screw mechanism open, is easy to pull down maintain and replace.
4, reduce number of parts, simplify loaded down with trivial details dismounting step, reduce fit tolerance and cumulative limit, reduce part difficulty of processing, reach and be easy to safeguard, improve the object of stability.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is for tearing screw dop overall structure schematic diagram open;
Fig. 2 is jaw cylinder annexation schematic diagram.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Fig. 1, Fig. 2, one tears screw dop open, comprise a pair screw jaw 2 be connected on jaw cylinder 1 liang of jaw, described screw jaw 2 one end is stiff end 21, stiff end 21 is fixed on described jaw, and the other end is bare terminal end 22, and bare terminal end 22 is for being inverted L shape, bare terminal end 22 is connected with batch bar axis of guide 3, and bare terminal end 22 offers to the sections inner side of downward-extension the arc-shaped slot coordinated with the described batch of bar axis of guide 3.Described jaw cylinder 1 is fixed by cylinder mounting block 4.
Chucking power is realized by standard jaw cylinder, ensures stable chucking power.By coordinating with batch bar axis of guide, the inherent characteristic risen after using loosened screw, the section difference of clamping screw terminal and threaded portion realizes the object of gripping, maximized raising reliability.Dop is placed in the outside of tearing screw mechanism open, is easy to pull down maintain and replace.Reduce number of parts, simplify loaded down with trivial details dismounting step, reduce fit tolerance and cumulative limit, reduce part difficulty of processing, reach and be easy to safeguard, improve the object of stability.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
