Description

Technical Field

[0001] This utility model relates to the field of positioning auxiliary equipment technology, and in particular to a corner positioning device. Background Technology

[0002] During the assembly of aircraft passenger observation windows, cabin doors, and other structures, multiple L-shaped corner brackets need to be installed. The corner brackets are generally connected to the main structure by bolting, which requires drilling holes or countersunk holes in the L-shaped corner brackets to facilitate bolt connection.

[0003] The existing drilling or countersinking positioning method involves clamping one end of an L-shaped angle plate onto a bench vise, while the other end is suspended in the air. The drilling or countersinking is then performed on the suspended part. This method is inconvenient for workers and prone to quality problems: First, the angle plate is relatively small, and the suspended part is close to the bench vise, making it easy for the drill bit to hit the bench vise after passing through the angle plate during drilling. Second, the angle plate is prone to tilting or shaking during drilling and countersinking, making it difficult to guarantee the perpendicularity and diameter accuracy of the hole.

[0004] Therefore, there is an urgent need for a corner positioning device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a corner plate positioning device that can keep the corner plate stable during drilling, ensure product quality, and protect the drill bit from collisions.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A corner piece positioning device is provided, comprising:

[0008] The positioning component includes a positioning surface and a first clamping surface. The positioning surface and the first clamping surface are connected at an angle. A first positioning groove is provided on the positioning surface. The first positioning groove is located at one end of the positioning surface connected to the first clamping surface. A first groove is provided on the bottom surface of the first positioning groove. One end of the corner piece to be processed is limited in the first positioning groove. The other end of the corner piece is pressed against the first clamping surface.

[0009] A clamping structure abuts against the corner piece and is used to clamp the corner piece and the first clamping surface.

[0010] As an optional solution for the corner positioning device, a first chamfer is provided between the positioning surface and the first clamping surface.

[0011] As an optional solution for the corner positioning device, the width of the first chamfer is 2mm-4mm.

[0012] As an alternative solution for the corner piece positioning device, a plurality of first positioning grooves are provided on the positioning surface, and the bottom surface of each first positioning groove is provided with the first groove.

[0013] As an optional solution for the corner piece positioning device, the positioning member further includes a second clamping surface, which is angularly connected to the end of the positioning surface away from the first clamping surface. The positioning surface is also provided with a second positioning groove, which is located at the end of the positioning surface connected to the second clamping surface. A second groove is provided on the bottom surface of the second positioning groove.

[0014] As an optional solution for the corner piece positioning device, a second chamfer is provided between the positioning surface and the second clamping surface.

[0015] As an optional solution for the corner positioning device, the width of the second chamfer is 2mm-4mm.

[0016] As an optional solution for the corner piece positioning device, a plurality of second positioning grooves are provided on the positioning surface, and a second groove is provided on the bottom surface of each second positioning groove.

[0017] As an alternative solution for the corner piece positioning device, the clamping structure includes a fixing member and several moving members.

[0018] As an optional solution for the corner positioning device, the positioning component is a box structure.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a corner piece positioning device. By setting a positioning groove on the positioning element and a first recess on the bottom surface of the first positioning groove, one end of the corner piece to be processed can directly contact the bottom surface of the first positioning groove, initially achieving the positioning of the corner piece. When the drill bit passes through the corner piece, the first recess can accommodate the protruding portion of the drill bit, allowing the drill bit to fully process the corner piece, ensuring processing quality. Furthermore, the first recess avoids the drill bit, preventing collision between the positioning element and the drill bit, ensuring the drill bit's service life and saving production costs. One end of the corner piece is confined within the positioning groove, while the other end is clamped against the first clamping surface by a clamping structure, further preventing the corner piece from tilting or shaking during drilling. This ensures the corner piece remains stable during processing, further guaranteeing the dimensional accuracy of the product, improving the product yield, reducing operational difficulty, and facilitating worker operation.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] like Figure 1 and Figure 2 As shown, the corner piece positioning device of this embodiment includes a positioning element 100 and a clamping structure 200. The positioning element 100 includes a positioning surface 110 and a first clamping surface 120, which are connected at an angle. A first positioning groove 111 is provided on the positioning surface 110, located at the end where the positioning surface 110 connects to the first clamping surface 120. A first groove 112 is provided on the bottom surface of the first positioning groove 111. One end of the corner piece to be processed is limited within the first positioning groove 111, and the other end of the corner piece abuts against the first clamping surface 120. The clamping structure 200 abuts against the corner piece and is used to clamp the corner piece and the first clamping surface 120.

[0031] Based on the above design, the corner piece positioning device provided in this embodiment, by setting a first positioning groove 111 on the positioning member 100 and a first groove 112 on the bottom surface of the first positioning groove 111, allows one end of the corner piece to be processed to directly contact the bottom surface of the first positioning groove 111, thus initially achieving the positioning of the corner piece. When the drill bit passes through the corner piece, the first groove 112 can accommodate the part of the drill bit that has passed through, allowing the drill bit to fully process the corner piece, ensuring processing quality. Furthermore, the first groove 112 can avoid the drill bit, preventing the positioning member 100 from colliding with the drill bit, ensuring the service life of the drill bit, and saving production costs. The other end of the corner piece is pressed against the first clamping surface 120 by the clamping structure 200, which can further prevent the corner piece from tilting or shaking during drilling, allowing the corner piece to remain stable during processing, further ensuring the dimensional accuracy of the product, improving the product yield, reducing the difficulty of operation, and facilitating worker operation.

[0032] In this embodiment, the depth of the first positioning groove 111 can be set to 1mm-2mm, which can both ensure the positioning of the corner piece to be processed and control the amount of cutting, thus reducing the processing difficulty. For example, the depth of the first positioning groove 111 can be set to 1mm, 1.5mm, 2mm, etc. The width and length of the first positioning groove 111 can be processed according to the width of the corner piece, which will not be described in detail here.

[0033] It should be noted that the width of the first groove 112 can be set to 3mm-5mm, the depth can be set to 5mm-6mm, and the length can be adjusted according to the drilling position of the corner piece. For example, the width of the first groove 112 is 3mm, 4mm, 5mm, etc., and the depth can be 5mm, 5.5mm, 6mm, etc.

[0034] Furthermore, the positioning component 100 has a box structure, that is, the interior of the positioning component 100 is hollow. While ensuring that the positioning component 100 has sufficient structural strength, it can reduce the weight of the positioning component 100, making the positioning component 100 lighter and easier to handle. It can be flexibly used in various processing sites and is convenient for workers to operate.

[0035] In this embodiment, the positioning element 100 is made of high-quality carbon structural steel, which has high hardness and corrosion resistance, high structural strength, and can withstand large impacts during drilling or countersinking, thus having a good service life. In some other embodiments, the positioning element 100 may also be made of stainless steel, aluminum alloy, or other materials, which will not be elaborated here.

[0036] Optionally, multiple first positioning grooves 111 can be provided on the positioning surface 110, and each first positioning groove 111 has a first groove 112 on its bottom surface, thereby enabling the simultaneous positioning of multiple corner pieces, saving the time used to position and clamp multiple corner pieces, improving processing efficiency, and facilitating mass production. In this embodiment, two first positioning grooves 111 are provided on the positioning surface 110. In some other embodiments, three, four, etc., can also be provided, which will not be elaborated here.

[0037] Furthermore, a first chamfer 130 is provided between the positioning surface 110 and the first clamping surface 120. Since the corner piece is a bent part, its bent part has a certain bending radius. In order to avoid the sharp corner formed by the connection between the positioning surface 110 and the first clamping surface 120 abutting against the bent part of the corner piece and causing the corner piece to wobble, the first chamfer 130 is provided so that the two ends of the corner piece can respectively fit against the bottom surface of the first positioning groove 111 and the first clamping surface 120, ensuring the stability of the corner piece during processing.

[0038] Optionally, the width of the first chamfer 130 can be set to 2mm-4mm. This avoids both excessive cutting amount of the first chamfer 130, which would cause processing difficulties, and insufficient cutting amount, which would cause the first chamfer 130 to abut against the bent part of the corner piece, resulting in positioning failure. For example, the width of the first chamfer 130 can be set to 2mm, 3mm, 4mm, etc.

[0039] Furthermore, the positioning member 100 may also include a second clamping surface 140, which is angularly connected to the end of the positioning surface 110 away from the first clamping surface 120. The positioning surface 110 is also provided with a second positioning groove 113, which is located at the end where the positioning surface 110 and the second clamping surface 140 are connected. A second groove 114 is provided on the bottom surface of the second positioning groove 113.

[0040] It is understandable that when the second positioning groove 113 and the first positioning groove 111 are the same size, the positioning component 100 can increase the positioning position of the same type of corner piece, further increase the number of corner pieces that can be positioned on the positioning component 100, and improve the efficiency of corner piece production and processing; when the second positioning groove 113 and the first positioning groove 111 are different in size, the second positioning groove 13 and the first positioning groove 111 can be used to position corner pieces of different specifications and models, thereby expanding the application range of the corner piece positioning device.

[0041] Optionally, multiple second positioning grooves 113 can be provided on the positioning surface 110, and each second positioning groove 113 has a second groove 114 on its bottom surface, which can simultaneously position multiple corner pieces of different specifications, improve processing efficiency, and facilitate mass production. In this embodiment, two second positioning grooves 113 are provided on the positioning surface 110. In some other embodiments, three or four grooves may also be provided, which will not be elaborated here.

[0042] Furthermore, a second chamfer 150 is provided between the positioning surface 110 and the second clamping surface 140. The second chamfer 150 can refer to the structure and function of the first chamfer 130 to ensure that both ends of the corner piece are respectively in contact with the bottom surface of the second positioning groove 113 and the second clamping surface 140, thereby achieving the stability of the corner piece. Optionally, the width of the second chamfer 150 is 2mm-4mm. For example, it is set to 2mm, 3mm, 4mm, etc., which will not be elaborated here.

[0043] In some embodiments, the clamping structure 200 includes a fixing member 210 and a plurality of moving members 220. The moving members 220 are movably connected to the fixing member 210, and the fixing member 210 is connected to the positioning member 100. At least a portion of the fixing member 210 is spaced apart from the first clamping surface 120. One end of the corner piece is disposed between the first clamping surface 120 and the fixing member 210. At least one moving member 220 can approach or move away from the first clamping surface 120 to clamp the corner piece. Alternatively, at least a portion of the fixing member 210 is spaced apart from the second clamping surface 140, and at least one moving member can approach or move away from the second clamping surface 140. Or, a portion of the fixing member 210 is spaced apart from the first clamping surface 120, and a portion of the fixing member 210 is spaced apart from the second clamping surface 140. The plurality of moving members 220 can clamp the plurality of corner pieces onto the positioning member 100 respectively, thereby fixing the corner piece. For example, the fixing member 210 may be provided with a threaded hole, and the moving member 220 is provided as a bolt, which is threadedly connected to the threaded hole, so as to press the corner piece against the positioning member 100.

[0044] In some other embodiments, the clamping structure 200 can also directly use mature clamping tools, such as pliers, which will not be described in detail here.
