Detailed Description

The following description of the embodiments of the present invention is provided in connection with the accompanying drawings.

Referring to fig. 1 and 2, an embodiment of the utility model discloses a press-fitting tool for a hinge, which can be used for simply and efficiently correcting and press-fitting a hinge which is deformed and out of round.

The utility model discloses a press fitting tool for a hinge, which comprises a press fitting assembly 1 and a guide assembly 2. Wherein, crimping subassembly 1 extrudees the hinge, resumes the shape of the hinge hole of deformation. And the guide assembly 2 guides the crimping assembly 1 to move in a direction of pressing the hinge. The recalibration press mounting of the hinge can be simply, conveniently and efficiently realized through the matching of the crimping component 1 and the guide component 2.

Referring to fig. 3, in the present embodiment, the crimping assembly 1 includes a crimping block 11 and a base 12, and the crimping block 11 is disposed above the base 12. The inner wall of the pressure joint block 11 and the inner wall of the base 12 form a placing cavity 13, and the shape of the cavity of the placing cavity 13 is matched with the shape of the outer wall of the hinge.

In the using process, the hinge which is deformed is placed in the placing cavity 13 formed by the crimping block 11 and the base 12, the whole crimping component 1 directly extrudes the hinge placed in the placing cavity 13 by applying external force to the crimping component 1, and the extrusion can be carried out for multiple times until the hinge recovers the deformation. The mutual matching between the cavity shape of the placing cavity 13 and the outer wall shape of the hinge means that the cavity shape of the placing cavity 13 is the same as the original standard shape of the hinge needing to be deformed and has the same contour. In use, the outer contour of the hinge placed in the placing cavity 13 is compressed by the crimping assembly 1, and the outer contour of the hinge tends to compress the shape of the inner wall, i.e. the shape of the cavity of the placing cavity 13. Therefore, in this embodiment, it is necessary to ensure that the shape of the placing cavity 13 is the same as and the contour of the original standard shape of the hinge to be pressed, so as to achieve the purpose of restoring the shape of the hinge by pressing.

In connection with practical applications, the press-fitting tool for a hinge disclosed in this embodiment is generally used to restore the shape of a flat sheet hinge used in an airplane, and the outer wall of the flat sheet hinge is generally in the shape of a circular arc, so in this embodiment, it is preferable that the cavity of the placing cavity 13 is in the shape of a circular arc. Specifically, a design may be adopted in which the crimping block 11 is an arc-shaped block, and the end face of the crimping block 11 is a semicircular arc face. The base 12 is designed to include two parts, namely an arc part and a flat plate part, wherein the end face of the arc part is a quarter arc surface, and the end face of the arc part and the end face of the crimping block 11 are spliced together to form a three-quarter arc surface. The arcuate portion and the flat portion of the base 12 are integrally formed. By adopting the design, the arc-shaped placing cavity 13 can be effectively formed by the pressure connecting block 11 and the base 12, a flat sheet hinge used by an airplane can be accommodated, and the flat sheet hinge can be further corrected and pressed.

In order to ensure that when force is applied to crimping assembly 1 from the outside, crimping assembly 1 moves in the direction of squeezing the hinge in placing cavity 13, the motion of crimping assembly 1 during use of the crimping tool of the hinge needs to be guided in a track. In this embodiment, a guide assembly 2 is provided to guide the movement of the crimping assembly 1. And a guide groove 3 is formed in the end face of the crimping block 11 on the same side as the base 12, and the guide assembly 2 is placed in the guide groove 3. With the above arrangement, the crimping assembly 1 is limited to move only in the direction of the guide assembly 2 after being applied with an external force, i.e. in the direction of pressing the hinge in the placing cavity 13, thereby completing the pressing of the hinge.

Referring to fig. 4, in order to directly transmit the force applied to the crimping component 1 from the outside to the hinge disposed inside the crimping component 1, and to reduce the energy loss of the external force during the transmission process as much as possible, in the embodiment, the method is implemented by directly contacting the crimping component 1 with the hinge disposed inside. In particular, the inner wall of the placing cavity 13 is arranged to fit the outer surface of the hinge placed therein in this embodiment. In the process of producing the press-fitting tool for manufacturing the hinge disclosed in the embodiment, the press-fitting tool matched with the hinge needs to be designed according to the size of the hinge, the hinges with different external shapes correspond to the placing cavities 13 with different shapes, and the hinges with different sizes correspond to the placing cavities 13 with different sizes.

In order to improve the extrusion effect of the crimping component 1 on the hinge and avoid deformation of the crimping component 1 in the process of applying force to the outside of the crimping component 1, in this embodiment, the thicknesses of the crimping block 11 and the base 12 in the crimping component 1 are not smaller than the radius of the hinge hole of the hinge. And to ensure that the hinge can be completely realigned, the length of the placement cavity 13 is not less than the length of the hinge in this embodiment. However, in the actual production and manufacturing process of the press-fitting tool for the hinge, the actual application scene of the press-fitting tool also needs to be considered, the press-fitting tool in the embodiment is mainly applied to the correction press-fitting of the flat sheet hinge of the airplane, and the size design of the press-fitting tool needs to be carried out in combination with the size of the flat sheet hinge for the airplane. Meanwhile, the press-fitting tool of the hinge disclosed in the present embodiment is generally nipped with pliers, and therefore the size of the press-fitting tool needs to be in accordance with the ease of use of the operator.

In terms of the selection of the manufacturing materials of the press-fitting tool of the hinge, if the hardness of the press-fitting component 1 is greater than that of the hinge to be corrected and pressed, the hinge is easily damaged or abraded, and the recycling of the hinge is not facilitated. Therefore, the material hardness of the crimp assembly 1 in this embodiment is less than that of the hinge. In combination with practical circumstances, the flat plate hinge for an airplane is generally made of alloy steel, among materials with hardness lower than that of alloy steel, hard aluminum alloy has good mechanical properties, high strength, easy processing and low density, aluminum bronze alloy has high strength, hardness and wear resistance, and is relatively cheap, so that the manufacturing cost can be reduced, and therefore, in the embodiment, the crimping component 1 is preferably made of hard aluminum alloy material or aluminum bronze alloy material.

Referring to fig. 1 and 4, in order to apply a force to the crimping component 1 and ensure that the force application tool and the crimping component 1 do not slide relative to each other during an external force application process, it is preferable that a contact surface between the external force and the crimping component 1 is a flat surface rather than an arc surface. Specifically, in the present embodiment, in the crimping assembly 1, the upper surface 111 of the crimping block and/or the lower surface 121 of the base are provided with the working surface 14, and the working surface 14 is a plane. The upper surface 111 of the crimping block and the lower surface 121 of the base can be simultaneously provided with the planar working surface 14, and this scheme can be preferably applied to the situation that the crimping component 1 needs to be pressed up and down simultaneously by the pressing force towards the placing cavity 13, such as using pliers to clamp the crimping component 1 up and down to perform a large force pressing. The flat working surface 14 may be formed only on the upper surface 111 of the pressure block, and this is preferably applied to the case where the pressure unit 1 is pressed only from above the pressure block 11, or the flat working surface 14 may be formed only on the lower surface 121 of the base, and this is preferably applied to the case where the pressure unit 1 is pressed only from below the base 12. The specific design scheme is that the scheme for opening the working surface 14 of the crimping component 1 is designed according to the actual external force application condition.

In order to improve the force conversion efficiency of the process that the external force acts on the crimping component 1, so that the crimping component 1 extrudes the built-in hinge, and simultaneously avoid the situation that the crimping component 1 is locked and cannot slide in the extrusion process, the plane where the working surface 14 is located and the plane where the guide groove 3 is located are perpendicular to each other in the embodiment. When the plane of the working surface 14 and the plane of the guide groove 3 are perpendicular to each other, the force application tool applies force through the working surface 14 so that the pressing direction of the external force is downward in the direction perpendicular to the working surface 14, that is, in the direction parallel to the guide member 2, and toward the placing chamber 13. The guide groove 3 and the guide component 2 define the moving direction of the crimping component 1, namely, the moving direction is along the direction of the guide component 2 towards the placing cavity 13, namely, the pressing force is consistent with the moving direction of the stressed crimping component 1.

In order to facilitate placing and taking out the hinge placed in the placing cavity 13, the crimping component 1 needs to be detachable, and meanwhile, in order to facilitate installation of the guide component 2, the guide component 2 is arranged in a semi-fixed manner in the embodiment, specifically, the guide component 2 is fixedly connected with the guide groove 3 on the crimping block 11; or the guide assembly 2 is fixedly connected with the guide groove 3 on the base 12.

In order to reduce the manufacturing cost of the press-fitting tool for the hinge and simplify the assembly process, the guide member 2 in this embodiment is a guide pin. The end shape of the guide pin is matched with the shape of the guide groove 3, and the guide pin and the guide groove are matched with each other for use. Preferably, the guide groove 3 adopts the dovetail design, improves the stability of being connected of uide pin and guide groove 3, avoids in the pressure equipment instrument use, and external force extrusion crimping subassembly 1, the condition that the uide pin easily drops appears.

Referring to fig. 1 to 4, the use process of the press-fitting tool for a hinge disclosed in this embodiment is as follows: and (3) placing the hinge to be corrected and pressed on the base 12, then placing the pressing block 11 above the hinge, and finally inserting the movable end of the guide assembly 2 into the guide groove 3 to complete the assembly of the pressing tool of the hinge. After the assembly is completed, the crimping component 1 is squeezed by external force, the working face 14 of the crimping component 1 can be clamped by a pair of large-force pliers, and the large-force pliers are pinched forcibly until the out-of-round hinge hole returns to a round shape, so that the correction press-fitting of the hinge is completed.

The press-fitting tool for the hinge disclosed by the embodiment can quickly correct the deformed hinge through simple and convenient operation, and the technical scheme can be suitable for deformation recovery work of the hinge used by the airplane on a large scale, so that the reuse rate of the hinge is improved. Meanwhile, the press-fitting tool for the hinge disclosed by the embodiment is simple in structure, low in material selection requirement, capable of reducing manufacturing difficulty and production cost and capable of being popularized and manufactured in a large range.
