Description

Technical Field

[0001] This utility model belongs to the field of aircraft airframe structural component assembly technology, specifically relating to a fuse quick positioning, shearing and bending pliers. Background Technology

[0002] During the repair of aircraft structural components, before and after the installation of elastic tubing and covering fabric, the covering fabric needs to be secured to the corresponding frame with fuses. Figure 7 and Figure 8 As shown, where Figure 7 Before installing the flexible hose and covering fabric. Figure 8 After the flexible hose and covering fabric are installed, during the covering process, both ends of a fuse need to be inserted into the mounting holes of two adjacent fuses. Generally, a single unit has approximately 620 fuse mounting holes, with equal spacing between them; approximately 310 fuses of equal length are required, and the fuse shape is as follows... Figure 9 As shown.

[0003] The traditional method for preparing fuses involves the operator first measuring the length of a long fuse, then cutting it into several equal lengths. Each fuse is then individually bent at both ends using ordinary pliers. Because the number of fuses required for repair is enormous, this traditional cutting method is inefficient. Furthermore, the length and bending position of the fuses depend entirely on the operator's skill level, leading to human error in both cutting length and bending angle. This compromises fuse quality and consumes a significant amount of labor. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing aviation fuse cutting and bending methods, which are characterized by low efficiency and uncontrollable fuse length and bending angle, resulting in poor fuse quality uniformity. In response, this invention provides a fuse quick positioning, cutting, and bending pliers.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A fuse quick positioning, cutting, and bending pliers includes a first pliers body and a second pliers body that are X-shaped and cross-hinged, a first pliers head extending from the front end of the first pliers body, and a second pliers head extending from the front end of the second pliers body; it also includes a cutting limiter, a bending head, and a bending limiter.

[0007] The first clamp head and the side wall that interacts with the second clamp head have a shearing surface, and the side wall symmetrical to the location of the shearing surface has a shearing limiting member for contacting one end of the original fuse to limit the shearing length of the fuse; the shearing surface and the shearing limiting member are close to the root of the first clamp head;

[0008] The second clamp head is provided with a shearing blade at a position corresponding to the shearing action surface;

[0009] The first clamp head has a vertically arranged bending head on its top and the sidewall that interacts with the second clamp head. The bending head includes two symmetrically arranged steel plates that form a rectangular groove for bending the fuse. The edges of the two steel plates have coaxially opened arc grooves for accommodating the fuse to be bent. The opening of the arc grooves faces the second clamp head.

[0010] The top dimension of the second pliers head matches the dimension of the rectangular groove on the first pliers head, which allows the fuse to be bent to be pressed into the rectangular groove to obtain a shaped fuse.

[0011] The bending limiting member is vertically disposed on the outer side wall of the steel plate and is used to contact one end of the fuse to be bent in order to limit the bending position of the fuse.

[0012] Furthermore, the shearing limiting member and the bending limiting member are arranged in parallel on the same side of the first clamp head.

[0013] Furthermore, the shearing limiting member includes a first positioning plate and a first limiting plate that are perpendicularly connected; the end of the first positioning plate is perpendicularly fixedly connected to the bottom of the side wall of the first clamp head, and the first positioning plate is coplanar with the shearing action surface;

[0014] The inner wall of the first limiting plate can contact the end of the original fuse to limit the fuse cutting length.

[0015] Furthermore, the bending limiting component includes a second positioning plate and a second limiting plate that are perpendicularly connected; the end of the second positioning plate is fixedly connected perpendicularly to the side wall of the bending head, and the second positioning plate is parallel to the axis of the arc groove;

[0016] The inner wall of the second limiting plate can contact the end of the fuse to be bent in order to limit the bending position of the fuse.

[0017] Furthermore, the molded fuse includes a first segment, a second segment, and a third segment connected vertically in sequence; the first segment and the third segment are arranged symmetrically.

[0018] The length of the rectangular groove is equal to the length of the second section of the molded fuse;

[0019] The distance from the second limiting plate to the steel sheet near the second limiting plate is equal to the length of the first or third section of the formed fuse;

[0020] The distance from the first limiting plate to the shearing blade is equal to the total length of the formed fuse.

[0021] Furthermore, the top of the bending head is also provided with an arc-shaped baffle, and the two ends of the arc-shaped baffle are smoothly connected to the tops of the two steel sheets respectively.

[0022] Furthermore, the shearing limiter, bending limiter, bending head, and arc-shaped baffle are made of 1Ci18Ni9Ti.

[0023] The advantages of this utility model are:

[0024] 1. This utility model of a quick-cutting, positioning, and bending pliers includes a cutting blade, a cutting limiter, a bending head, and a bending limiter. The bending head has an arc-shaped groove for accommodating a fuse and a rectangular groove for bending the fuse. The root of the first pliers head has a cutting limiter that limits the cutting length, and the top side has a bending limiter that limits the bending position length and position. Since the dimensions of the rectangular groove on the bending head, the cutting limiter, and the bending limiter are determined according to the relevant dimensions of the fuse to be formed, quick cutting and bending of the fuse is achieved, avoiding human error caused by manual cutting or bending operations.

[0025] 2. The cutting and bending operation of this utility model is simple. It can cut or bend separately, or it can cut one fuse while bending another fuse at the same time, which greatly improves the production efficiency of the required fuses.

[0026] 3. The use of this utility model of quick-cutting, positioning, and bending pliers enables rapid mass production of aviation fuses, thereby improving aircraft modification efficiency and repair quality, and greatly saving labor costs. Attached Figure Description

Detailed Implementation

[0037] The embodiments of the present invention are described in detail below. These embodiments are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] The required molded fuse is defined as consisting of a first segment, a second segment, and a third segment located in the same plane and connected perpendicularly in sequence; the first and third segments are symmetrically arranged. The length of the second segment is defined as 'a', and the lengths of the first and third segments are defined as 'b'.

[0039] Reference Figure 1 This embodiment provides a fuse quick-positioning, cutting, and bending pliers, including a pliers body, a bending head 5, a cutting limiter 6, and a bending limiter 7. The pliers body is a standard part, including a first pliers 1 and a second pliers 2 that are X-shaped and cross-hinged, a first pliers head 3 extending from the front end of the first pliers body, and a second pliers head 4 extending from the front end of the second pliers body. The front ends of the first pliers 1 and the second pliers 2 are connected by a pivot.

[0040] Reference Figures 2-3The first clamp head 3 has a shearing surface 301 on its lower end and on the side wall facing the second clamp head 4. A shearing limiting member 6 is located on the side wall symmetrical to the shearing surface at the lower end of the first clamp head 3. The shearing limiting member 6 contacts one end of the original fuse 9 to limit the shearing length of the fuse. The shearing surface and the shearing limiting member are located at the root of the first clamp head (near the pivot). Specifically, the shearing limiting member 6 is a steel plate, including a first positioning plate 601 and a first limiting plate 602 that are perpendicularly connected. The end of the first positioning plate 601 is vertically fixedly connected to the bottom of the side wall of the first clamp head, and the first positioning plate is coplanar with the shearing surface. The inner side wall of the first limiting plate 602 can contact the end of the original fuse 9 to limit the shearing length of the fuse.

[0041] The first clamp head 3 has a bending head 5 perpendicularly disposed on its top sidewall facing the second clamp head. The bending head 5 includes two symmetrically arranged first steel plates 501 and second steel plates 502, forming a rectangular groove for bending the fuse. The edges of the two steel plates have coaxially formed arcuate grooves 302 for accommodating the pre-fabricated fuse 10 (the fuse formed after cutting), and the opening of these arcuate grooves faces the second clamp head. A bending limiting member 7 is disposed on the sidewall of the second steel plate 502 of the bending head, for contacting one end of the fuse to be bent to limit the bending position of the fuse. The bending limiting member 7 is parallel to the cutting limiting member 6 and located on the same side of the first clamp head. The bending limiting member 7 is a steel plate, including a second positioning plate 701 and a second limiting plate 702 perpendicularly connected. The end of the second positioning plate 701 is perpendicularly fixedly connected to the sidewall of the second steel plate 502, and the second positioning plate 702 is parallel to the axis of the arcuate groove. The inner wall of the second limiting plate can contact the end of the pre-fabricated fuse 10 to limit the bending position of the fuse.

[0042] Reference Figure 4 A shearing blade 401 is provided on the second clamping head 2 at a position corresponding to the shearing action surface of the first clamping head. The shearing blade 401 cooperates with the shearing action surface 301 on the first clamping head to cut the original fuse 9. Specifically, the distance from the first limiting plate 602 to the shearing blade 401 is equal to the total length of the formed fuse 11, i.e., a+2b.

[0043] The top dimension of the second clamp head 2 matches the dimension of the rectangular groove on the first clamp head, enabling the pre-made fuse 10 to be pressed into the rectangular groove of the bending head, thus bending the fuse into shape. Specifically, the length of the rectangular groove (along the direction of the second positioning plate) is equal to the length a of the second segment of the formed fuse, and the distance from the second limiting plate to the second steel plate 502 is equal to the length b of the first (or third) segment of the formed fuse.

[0044] To make the shearing positioning bending pliers look aesthetically pleasing and to prevent the two steel plates of the bending head from scratching the operator, an arc-shaped baffle 8 is designed on the top of the bending head in this embodiment. The two ends of the arc-shaped baffle are smoothly connected to the top of the two steel plates of the bending head.

[0045] In this embodiment, the arc-shaped baffle, bending head, bending limiter, and shearing limiter are all made of 1Ci18Ni9Ti material.

[0046] This embodiment also provides a method for using aviation fuse quick-cutting and positioning bending pliers:

[0047] Step 1: Open the first clamp head 3 and the second clamp head 4, place the original fuse 9 on the shearing surface 301, and make one end of the original fuse contact the first limiting plate 602 of the shearing limiting member 6. Forcefully clamp the first clamp body 1 and the second clamp body 2, and the shearing blade 401 will cut the pre-fabricated fuse 10 to the required length. Figure 5 As shown.

[0048] Step 2: Open the first and second clamps, place the pre-made fuse 10 into the arc groove 302 on the bending head, and ensure that one end of the pre-made fuse contacts the second limiting plate 702 of the bending limiting member 7. Firmly squeeze the first and second clamps together, pressing the top of the first clamp into the rectangular groove of the bending head to obtain the required shaped fuse 11. Figure 6 As shown.

[0049] To improve the efficiency of fuse manufacturing, such as Figure 5 This device allows for the simultaneous positioning of both a standard fuse and a pre-fabricated fuse, enabling rapid shearing and bending of the fuse. The operator can adjust the dimensions of the rectangular groove in the bending head, the length of the first positioning plate in the shearing limiter, and the length of the second positioning plate in the bending limiter according to the specifications of the formed fuse.

[0050] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
