Abstract

The invention discloses a fixture clamping structure. The fixture clamping structure is characterized in that one threaded end of an anti-falling bolt is smaller than the other end, a screw with diameter larger than that of the bolt is arranged on one section, close to the threaded end, of middle of the anti-falling bolt, and the diameter of the large head of the anti-falling bolt is larger than that of the screw. A screw hole matched with the screw on the anti-falling bolt is formed in a limiting plate, and the anti-falling bolt and the limiting plate are penetratingly connected through a thread. In a manufacturing shop, a bolt tightening mode needs to be applied frequently to achieve the purpose of clamping, and the bolt is separated from other parts of a clamping fixture during application; by application of the anti-falling device of the clamping fixture, the bolt can be integrated on the clamping fixture, and waste of movement for taking and putting the bolt is eliminated. The fixture clamping structure is simple in structure, convenient to mount, safe in production and high in reliability, efficiency for clamping parts by workers can be improved, and movement steps of personnel are decreased.

Summary of the invention
the object of the present invention is to provide the anti-device that drops out of a kind of clamping tool, an anti-bolt that drops out, described anti-threaded one end that drops out bolt is less than the other end, there is one section of screw rod that diameter is larger than the diameter of bolt the described anti-bolt centre that drops out by threaded one end, and have the polished rod of a section less than screw diameter by the other end, the described anti-diameter at butt end that drops out bolt is larger than screw diameter; A limiting plate, has on described limiting plate and anti-drops out the screw that on bolt, screw rod matches, and the described anti-bolt that drops out is to prevent dropping out device by the clamping tool of screw thread cross-under with limiting plate.
technical solution of the present invention is such: a kind of frock clamping structure, comprise and prevent dropping out bolt, limiting plate, fixture location-plate, it is characterized in that installing and preventing dropping out bolt (1) between limiting plate (2) and location-plate (3).
described anti-threaded one end that drops out bolt (1) is less than the other end.
described anti-have one section of screw rod that diameter is larger than the diameter of bolt by threaded one end in the middle of dropping out bolt (1), and have the polished rod of a section less than screw diameter by the other end, and the described diameter at butt end of preventing dropping out bolt (1) is larger than screw diameter.
on described limiting plate (2), have and anti-bolt (1) screw that above screw rod matches that drops out.
Between limiting plate (2) and fixture location-plate (3), fastening bolt is housed.
The anti-end that drops out bolt (1) is enclosed in the through hole of limiting plate (2) and location-plate (3).
The anti-large end circle that drops out bolt (1) is arranged on limiting plate (2) end face.
The anti-termination that drops out bolt (1) is thread head, and thread head has boss to the anti-intermediate step dropping out between the large end circle of bolt (1), and boss is on location-plate (3).
Position, location-plate (3) intermediate throughholes hole is greater than anti-bolt (1) thread head that drops out.
The present invention's advantage is compared with prior art: in manufacturing industry workshop, often need to apply the mode of bolt tightening to reach the object of clamping, in application process, bolt is to be what to be separated with other parts of clamping tool, by applying the anti-device that drops out of above-mentioned clamping tool, bolt can be incorporated on clamping tool, eliminate the action waste of taking and placing bolt.The present invention is that a kind of safe and reliable clamping tool is prevented dropping out device, and it is simple in structure, is convenient to install, and can improve the efficiency of workman's clamping parts, reduces employee's action step.
Accompanying drawing explanation
? ?fig. 1 is the assembling schematic diagram of a kind of frock clamping structure application of the present invention.
fig. 2 is the anti-body construction schematic diagram that drops out bolt of a kind of frock clamping structure of the present invention.
in Fig. 1～Fig. 2, anti-bolt (1), limiting plate (2), the fixture location-plate (3) of dropping out.
The specific embodiment
for further setting forth 26S Proteasome Structure and Function of the present invention, below in conjunction with accompanying drawing, the present invention is elaborated, but be to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.
embodiment 1, as shown in Figure 1, a kind of frock clamping structure, comprises anti-drop out bolt, limiting plate, fixture location-plate.Anti-threaded one end that drops out bolt (1) is less than the other end, in the middle of preventing dropping out bolt (1), there is one section of screw rod that diameter is larger than the diameter of bolt by threaded one end, and have the polished rod of a section less than screw diameter by the other end, the described anti-diameter at butt end that drops out bolt (1) is larger than screw diameter; A limiting plate (2), limiting plate (2) passes through screw thread cross-under with the anti-bolt (1) that drops out; On described limiting plate (2), have and anti-bolt (1) screw that above screw rod matches that drops out.Apply when described clamping tool is anti-drops out device, first limiting plate (2) is installed to the outside of fixture location-plate (3), when installation, should make the screwed hole center line on limiting plate (2) overlap with the center line of the through hole on fixture location-plate (3); Then, will prevent dropping out bolt (1) and be screwed in the screwed hole of limiting plate (2), bolt microcephaly, through the through hole on fixture location-plate (3), is screwed in the screw on part and can plays clamping action; Now, prevent that dropping out bolt can be free to slide in the screwed hole of limiting plate (2), but can not drop out.
embodiment 2, the connectivity robustness of reinforcement limiting plate (2) and fixture location-plate (3), is connected safety and reliability like this fastening bolt nut being installed between limiting plate (2) and fixture location-plate (3).
