Abstract
The utility model relates to the technical field of bolt assembling, in particular to a double-head bolt quick installation device which comprises a bolt chuck (2), a connecting screw rod (6), a limiting cylinder (5), a spring (4), a slide jacking head (3) and a chunk locking shell (7). The connecting screw rod (6) penetrates through the limiting cylinder body (5). The spring (4) is sleeved on the lower portion of the connecting screw rod (6), and the other end of the spring (4) is connected with the slide jacking head (3). The bolt chuck (2) is a two-clack bolt chuck, is clamped outside the connecting screw rod (6), the limiting cylinder (5), the spring (4), and the slide jacking head (3), and is locked in the chunk locking shell (7). An assembly shell body (8) is sleeved outside the chunk locking shell (7).

Description
[technical field]
The utility model relates to double-screw bolt mounting technology field, specifically a kind of studs rapid installation device.
[background technology]
When main body fixes, when needing other annexes of assembling, can adopt studs usually, such as: mechanical sealing base, semiaxis support etc.Because the studs entire body all is external screw thread, the position of conveniently not tightening, usually need be with the end of an auxiliary nut screwing clamping of tightening at studs, make studs and auxiliary nut be linked to be an integral body, the recycling auxiliary nut is installed studs, auxiliary nut is screwed down after finishing installation again.At present, the conventional auxiliary device of tightening studs has two kinds of structures: a kind ofly be, make a special grommet nut earlier, during installation, earlier studs is tightened in the grommet nut, make studs and grommet nut be linked to be integral body, utilize grommet nut that studs is installed then, grommet nut is screwed down after finishing installation, the shortcoming of this way is the mounting torque that the screwing force of grommet nut surpasses studs sometimes, causes grommet nut to twist not get off again; Another kind of improved way is, make a special long nut earlier, the long nut other end is screwed into a limit screw, this long nut plays the effect of blind hole nut on the one hand, make long nut in case twist not get off on the other hand, the limit screw of its other end can be unclamped earlier, discharging the screw-down torque of long nut and studs, thereby long nut can be unloaded.Yet, more than the device mode of two kinds of routines not only exist problems such as complex operation, efficient is low, labour intensity is big, and also can damage the external screw thread of studs sometimes, use is absolutely unsafe.
[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of studs rapid installation device is provided, problems such as complex operation when not only having solved existing studs and installing, efficient is low, labour intensity is big, and can not damage the external screw thread of studs, use as safe as a house, convenient.
Design a kind of studs rapid installation device for achieving the above object, comprise double-screw bolt chuck 2, link screw rod 6, spacing cylinder 5, spring 4, top 3 and chuck locking shell 7 slides, described link screw rod 6 passes spacing cylinder 5, the bottom of described link screw rod 6 is arranged with spring 4, the other end of described spring 4 connects the top 3 of sliding, described double-screw bolt chuck 2 is two lobe double-screw bolt chucks, described double-screw bolt chuck 2 is clamped in link screw rod 6, spacing cylinder 5, spring 4, slide and come directly towards outside 3, described double-screw bolt chuck 2 is locked in the chuck locking shell 7, the described chuck locking shell 7 outer assembly shells 8 that are arranged with.
Described double-screw bolt chuck 2 inner surfaces are provided with internal thread, and the internal thread of described double-screw bolt chuck 2 is meshed with the external screw thread of studs 1.
Described double-screw bolt chuck 2 is locked in the chuck locking shell 7 by the screens steel ball.
The utility model is compared with prior art, novel structure, simply, since the auxiliary nut that auxiliary studs in the traditional method is installed make can quick deciliter two lobe double-screw bolt chucks, and clamping has the link screw rod in two lobe double-screw bolt chucks, spacing cylinder, spring and the top of sliding, two lobe double-screw bolt chucks are locked in the chuck locking shell, chuck is locked shell be arranged with assembly shell outward, utilize the structure of this device, when two lobe double-screw bolt chucks merge, can the Fast Installation studs, when two lobe double-screw bolt chucks separate, then can unload this two lobes double-screw bolt chuck fast, avoided two lobe double-screw bolt chucks to twist the situation of not getting off and taken place, not only simple to operate, convenient, labour intensity is low, the installation effectiveness height, its efficient can promote more than 500% at least, and can not damage studs, has guaranteed the quality of product.

[specific embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As accompanying drawing 1 to shown in the accompanying drawing 7, the utility model comprises: studs 1, double-screw bolt chuck 2, slide and come directly towards 3, spring 4, spacing cylinder 5, link screw rod 6, chuck locking shell 7 and assembly shell 8, link screw rod 6 passes spacing cylinder 5, the bottom of link screw rod 6 is arranged with spring 4, the other end of spring 4 connects the top 3 of sliding, double-screw bolt chuck 2 is two lobe double-screw bolt chucks, double-screw bolt chuck 2 inner surfaces are provided with internal thread, the internal thread of double-screw bolt chuck 2 is meshed with the external screw thread of studs 1, double-screw bolt chuck 2 is clamped in link screw rod 6, spacing cylinder 5, spring 4, slide and come directly towards outside 3, double-screw bolt chuck 2 is locked in the chuck locking shell 7 by the screens steel ball, the chuck locking shell 7 outer assembly shells 8 that are arranged with.
In the utility model, the link screw rod passes spacing cylinder and puts on spring then and be locked at and slide above the top, selects for use two lobe double-screw bolt chucks that this is clamped then; When studs up pushed up, the top of sliding began to move up and down in the double-screw bolt chuck, and spacing during in double-screw bolt chuck groove location when the top of sliding, the internal thread on the two lobe double-screw bolt chucks meshes with the external screw thread of studs, thereby holds studs tightly; The two lobe double-screw bolt chucks that use the screens steel ball will assemble the slip top are placed in the chuck locking shell, make the self-locking in the process that studs is installed of two lobe double-screw bolt chucks, thereby prevent that studs from skidding, and can't install; Put assembly shell at last, connecting rod 9 by chuck locking shell top connects spanner or electric screw driver, only needs when studs is installed that assembly shell is aimed at studs and presses down, and allows and slides the top screens in the double-screw bolt chuck, studs is held, and be installed on the workpiece, treat the studs installation after, assembly shell is upwards carried, slide and come directly towards spring-loaded, will skid off, thereby make double-screw bolt chuck opening, in order to rapidly it is unloaded.
The utility model is not subjected to the restriction of above-mentioned embodiment; other any do not deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
