Description
Technical Field
The application relates to the field of wing assembly, in particular to a handheld mounting structure for symmetrical steel sleeves in through holes, which is used for wing wallboard assembly.
Background
In the assembly process of large aviation parts, two steel sleeves are required to be symmetrically installed in a hole, and the assembly precision requirement of the steel sleeves is high. At present, because the steel sleeve is in transition fit with the hole, the steel sleeve is required to be placed in liquid nitrogen for cooling so as to be convenient for assembly, and an installer uses a riveter to knock the steel sleeve into the hole after shrinking. But impact load that the riveter brought when the installation can lead to steel bushing and hole to appear damaging, and the riveter strikes the steel bushing and lead to the steel bushing to appear slight deformation also can influence the installation accuracy of steel bushing.
Disclosure of Invention
Aiming at the problems existing in the prior art and meeting the requirements of quick installation, installation precision and the like, the application provides a structure which can be held by hand and is used for installing a symmetrical steel sleeve in a through hole.
The utility model provides a but handheld mounting structure that is used for symmetry steel bushing in through-hole, its characterized in that, its structure includes taut cover, locating sleeve for hole, locating sleeve for the steel bushing, top cover, knock pin, adapter sleeve, pull rod, and the adapter sleeve links to each other with the handheld part in rear end, under the hydraulic mechanism drive in the handheld part, drives taut cover through adapter sleeve and pull rod and packs into the downthehole of wallboard with the steel bushing.
The mounting structure for the symmetrical steel sleeve in the through hole is characterized in that the rear end of the pull rod is connected with the connecting sleeve through threads; the ejector pin is arranged in the long round chute of the connecting sleeve; the top sleeve is sleeved outside the connecting sleeve and connected with the top pin through a top thread; the positioning sleeve is arranged at the front end of the top sleeve and used for ensuring the assembly precision of the steel sleeve when the steel sleeve is assembled, and the positioning sleeve can be replaced between the positioning sleeve for the hole and the positioning sleeve for the steel sleeve according to different references when the steel sleeve is assembled; the tensioning sleeve is sleeved at the front end of the pull rod; the rear end of the connecting sleeve can be connected with a handheld part, a plunger pump structure is contained in the handheld part, and a push rod of the plunger pump is connected with a threaded hole in the middle of the push pin.
The application has the beneficial effects that: 1) The impact load caused by the knocking of the riveter is changed into hydraulic transmission, and the stress is uniform and stable. 2) The front end tensioning sleeve is simple and convenient to install, the steel sleeve can be quickly installed after being cooled from liquid nitrogen and taken out, and the steel sleeve can be assembled in a short time. 3) The replaceable positioning sleeve is matched with the hole by virtue of the excircle, so that the coaxiality between the steel sleeve and the hole and the tolerance requirement of the flanging and the end face clearance of the steel sleeve are easier to realize during installation.
The application is described in further detail below with reference to the drawings of embodiments.

Detailed Description
Referring to fig. 1-6, a structure for installing symmetrical steel sleeves in through holes, which can be held by hand, comprises a tensioning sleeve 1, a positioning sleeve 2 for holes, a positioning sleeve 3 for steel sleeves, a top sleeve 4, a top pin 5, a connecting sleeve 6, a pull rod 7 and a screw 8. The pull rod 7 is connected with the connecting sleeve 6 through threads; the ejector pin 5 is arranged in a long smooth groove of the connecting sleeve 6; the top sleeve 4 is arranged outside the connecting sleeve 6 and is connected with the top pin 5 through a screw 8; the positioning sleeve is arranged at the front end of the top sleeve and used for ensuring the assembly precision of the steel sleeve when the steel sleeve is assembled, and the positioning sleeve can be replaced between the positioning sleeve 2 for the hole and the positioning sleeve 3 for the steel sleeve according to different references when the steel sleeve is assembled; the tensioning sleeve 1 is arranged at the front end of the pull rod 7; the rear end of the connecting sleeve 6 is connected with a hand-held part 11, an electric hydraulic cylinder is contained in the hand-held part 11, and a push rod of the electric hydraulic cylinder is connected with a threaded hole in the middle of the push pin 5.
When the symmetrical steel sleeve is installed by using the structure, the positioning sleeve 2 for holes is attached to the wall plate 10 for positioning, the front steel sleeve is taken out from liquid nitrogen and is arranged on the tensioning sleeve 1, the tensioning sleeve 1 is assembled at the front end of the pull rod 7, the electric hydraulic cylinder of the handheld part 11 is started, the ejector pin 5 connected with the ejector sleeve 4 through the screw 8 is used as a fixed reference, and the ejector rod of the hydraulic cylinder is extended to drive the connecting sleeve 6, the pull rod 7 and the tensioning sleeve 1 to place the front steel sleeve into the hole of the wall plate 10. When the rear steel sleeve is installed, the steel sleeve positioning sleeve 3 is assembled and positioned with the front steel sleeve, and the operation is repeated.
