Abstract
The utility model belongs to fixture structural design technology, and relates to a quick-release clamping component for a fixture positioning part, which comprises a bayonet pin (1), a star nut (2) and a fastening part (3). A bayonet section is arranged on a polished shaft section on the left of the bayonet pin (1) and at a position close to a threaded section; the star nut (2) is screwed on threads (1a) of the bayonet pin (1); the fastening part (3) is an elongated plate; and a U-shaped fastening groove (3a) is arranged at the width edge of one end of the fastening part (3). Clamped plates can be assembled and disassembled rapidly by the quick-release clamping component suitable for operation in a small space, operation time is saved greatly, and assembly and disassembly efficiency is increased.
Description
Technical field
The utility model belongs to the tool structure designing technique, relates to a kind of quick-release clamp assembly that is used for type frame keeper.
Background technology
When aircraft assembles, often need to use the keeper on the assembly jig to clamp plate parts, the logical screw of handle that uses cooperates the handle nut to realize clamping.Its shortcoming is: during with screw of handle and handle nut clamping and positioning, need twist the handle nut fully when clamped of loading, unloading, just can extract screw of handle.Twisting nut fully needs the long period, when especially clamped more and loading, unloading frequency is higher, twists the screw waste for a long time; During nutting, operate very inconvenient on the keeper very compact in structure in addition, that the operating space is little.
Summary of the invention
The purpose of this utility model is: provide a kind of and can load and unload fast, be fit to the quick-release clamp assembly that is used for type frame keeper of little spatial operation, to save the operating time, improve the efficiency of loading and unloading.
The technical solution of the utility model is: be used for the quick-release clamp assembly of type frame keeper, it is characterized in that, it is made up of bayonet pin, star nut and fastener; Bayonet pin is a screwed axle of right section, in abutting connection with the position of thread segment a bayonet socket section is arranged in the optical axis section on the bayonet pin left side, this bayonet socket section is by the rectangular channel of two symmetries up and down, the bottom land of two rectangular channels is parallel, distance between two rectangular channel bottom lands is t, the star nut is screwed on the screw thread of bayonet pin, fastener is a rectangular plate, widthwise edges at an end of fastener has a U-shaped draw-in groove, the width of U-shaped draw-in groove is greater than the distance between two rectangular channel bottom lands on the bayonet pin, simultaneously, the width of U-shaped draw-in groove is less than the diameter of bayonet pin, and the thickness of fastener is less than the axial width of rectangular channel on the bayonet pin.
The utility model has the advantages that: can load and unload clamped plate fast, be adapted at little spatial operation, save the operating time greatly, improve the efficiency of loading and unloading.The utility model is adopted in evidence, and the efficiency of loading and unloading that has improved clamped plate is more than 10 times.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the bayonet pin in the utility model.
Fig. 3 is the structural representation of the fastener in the utility model.Among Fig. 3, figure below is the vertical view of last figure.
The specific embodiment
Below the utility model is described in further details.Referring to Fig. 1,2,3, be used for the quick-release clamp assembly of type frame keeper, it is characterized in that it is made up of bayonet pin 1, star nut 2 and fastener 3; Bayonet pin 1 is the axle that a right section is threaded 1a, in abutting connection with the position of thread segment a bayonet socket section is arranged in the optical axis section on bayonet pin 1 left side, this bayonet socket section is by the rectangular channel 1b of two symmetries up and down, the bottom land of two rectangular channel 1b is parallel, distance between two rectangular channel 1b bottom lands is t, star nut 2 is screwed on the screw thread 1a of bayonet pin 1, fastener 3 is rectangular plates, widthwise edges at an end of fastener 3 has a U-shaped draw-in groove 3a, the width t1 of U-shaped draw-in groove 3a greater than between two rectangular channel 1b bottom lands on the bayonet pin 1 apart from t, simultaneously, the width t1 of U-shaped draw-in groove 3a is less than the diameter of bayonet pin 1, and the thickness of fastener 3 is less than the axial width of rectangular channel 1b on the bayonet pin 1.
For the ease of operation, the end that fastener 3 has U-shaped draw-in groove 3a has one 30 °～60 ° bending.
Using method of the present utility model is:
1, star-like nut 2 is screwed on the end of thread 1a of bayonet pin 1, the other end of bayonet pin 1 is passed from the locating hole of location-plate 4 and plate 5, make location-plate 4 and plate 5 be in the optical axis section between the rectangular channel 1b and star-like nut 2 on the bayonet pin 1, then the U type groove 3a of fastener 3 is stuck in 1b on the rectangular channel of bayonet pin 1, tighten star-like nut 2, bayonet pin 1 is made axial-movement under screw drive, the fastener 3 that is stuck in 1b on bayonet pin 1 rectangular channel moves to plate 5 and location-plate 4 with bayonet pin 1, thereby has realized that plate 5 is pressed on the location-plate 4.
When 2, dismantling, only need unclamp star-like nut 2 slightly, can pull out fastener 3, extract bayonet pin 1 then, the location impaction state is just removed.
Following table provides the parameter of 3 embodiment of the utility model.Unit is mm in the table.
