The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment that obtains, belong to the scope of protection of the invention.
Referring to figs. 1 through shown in Figure 4, the present embodiment door machine hinge is installed fast alignment tool, comprises free bearing 1, lifting screw 2, lifting cone 3, support member 4 and with lifting screw 2 threaded engagement and be positioned at the hinge wheel 5 of free bearing 1 top; Free bearing 1 is two Semi separation types, comprises two sub-free bearing 1-1 that are oppositely arranged, and vertically is provided with gathering sill 1-2 along it on the inwall of sub-free bearing 1-1, and when two sub-free bearing 1-1 were involutory, free bearing 1 was whole cylindrical; In the space of lifting cone 3 between two sub-free bearing 1-1, and be installed on the bottom of lifting screw 2, can adopt the mode of welding to set firmly, the outer wall of lifting cone 3 is provided with the guide rail 3-1 that matches with gathering sill 1-2 on sub-free bearing 1-1 inwall; Support member 4 is between hinge wheel 5 and free bearing 1, and to support hinge wheel 5 and lifting screw 2, and support member 4 is provided with the through hole that passes for lifting screw 2.
adopt the present embodiment door machine hinge that fast alignment tool is installed and carry out the stud connection hole of the stud connection hole of arm support of portal hoist 6 and rotating disk 7 to timing, with reference to shown in Figure 1, first rotate hinge wheel 5, under the threaded engagement effect of hinge wheel 5 and lifting screw 2, making lifting screw 2 drive lifting cone 3 moves downward to the lowermost end of free bearing 1, this moment, the diameter d of free bearing 1 bottom was smaller value, successively insert stud connection hole rotating disk 7 on and the stud connection hole of arm support of portal hoist 6 with this aligning tool this moment, after insertion, rotation hinge wheel 5, make lifting cone 3 under the drive of lifting screw 2, along moving on the gathering sill 1-2 on sub-free bearing 1-1, promoting two sub-free bearing 1-1 moves away to both sides, the diameter d of free bearing 1 bottom is extended to gradually consistent with the diameter in the stud connection hole of arm support of portal hoist 6, with reference to shown in Figure 5, thereby arm support of portal hoist 6 firmly is fixed on rotating disk 7, the stud connection hole of arm support of portal hoist 6 and the stud connection hole of rotating disk 7 align fully at this moment, at the bottom end side of free bearing 1 with hinge on the pre-inserted stud connection hole that is filled to arm support of portal hoist 6, then rotating hinge wheel 5 reduces the diameter of free bearing 1, the present embodiment door machine hinge is installed fast alignment tool to be extracted out and unloads along the direction away from arm support of portal hoist 6, the hinge plug-in mounting is complete, can complete arm support of portal hoist 6 installs, with reference to shown in Figure 6.
For making in the present embodiment the motion of lifting cone 3 and sub-free bearing 1-1 steady, the wall thickness of sub-free bearing 1-1 is reduced gradually by top to bottom, thereby its inwall is taken the form of inclined plane, the conical surface of this inclined-plane and lifting cone 3 is suitable, the conical surface that is lifting cone 3 can be fitted fully with the inwall of sub-free bearing 1-1, has guaranteed robust motion.
Due to except lifting screw 2 and lifting cone 3 are fixed as one, be the building block system assembled relation between other each parts, fast alignment tool is installed is demountable structure to the present embodiment door machine hinge, is convenient to deposit.Certainly, also can keep its package assembly, so that hand-held carrying, top at sub-free bearing 1-1 also is provided with the wing lug 1-3 that turns up, turn up wing lug 1-3 can with sub-this body by integral forming of free bearing 1-1, in when carrying, adopt both hands respectively hand-held hold the wing lug 1-3 that turns up can whole carrying; Simultaneously, the wing lug 1-3 that turns up also can play position-limiting action, and namely behind the stud connection hole on the present embodiment door machine hinge installation fast alignment tool insertion rotating disk 7, the wing lug 1-3 that turns up on place, stud connection aperture capstan wall, is played position-limiting action by backstop.
The weight of fast alignment tool is installed for alleviating as much as possible the present embodiment door machine hinge, is convenient to hand-held carrying and operation use, sub-free bearing 1-1 is provided with loss of weight fabrication hole 1-4, and lifting cone 3 is provided with loss of weight fabrication hole 3-2.
The above, be only preferred embodiment of the present invention, is not the present invention to be done the restriction of other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not break away from,, to any simple modification, equivalent variations and remodeling that above embodiment does, still belong to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
