[0032] The utility model provides a beam hole making template, which includes a template body and a positioning block; the positioning block is provided on the template body and defines the beam placement position on the template body; a bottom hole is provided on the template body corresponding to the beam placement position, the bottom hole passes through the template body, and the bottom hole corresponds to the hole required to be opened on the beam. The positioning block is provided in the beam hole making template, so that the position of the beam on the template body can be quickly positioned by the positioning block, and the bottom hole is provided on the template body, so that the position of the beam required to be opened can be quickly positioned, thereby eliminating the need to manually mark the beam, thereby improving processing efficiency, reducing the influence of human factors, improving processing accuracy, and making it less prone to errors during processing. In addition, the cost is low, the operation is simple, and the use is convenient, which reduces the skill requirements for the operator.

[0033] Please refer to Figure 1 and Figure 2 This embodiment provides a stringer hole-making template 100, which is mainly used to position the stringer 200 when making holes in the stringer 200 to improve hole-making efficiency and processing accuracy. Specifically, in one embodiment, the stringer 200 is used in a rocket shell.

[0034] The beam hole template 100 includes a template body 10 and a positioning block 20. The positioning block 20 is disposed on the template body 10 and defines a beam placement position 11 on the template body 10. When drilling a beam 200, the beam 200 can be placed in the beam placement position 11. The positioning block 20 abuts against the beam 200, allowing the beam 200 to be quickly positioned. A bottom hole 12 is formed on the template body 10 corresponding to the beam placement position 11. The bottom hole 12 passes through the template body 10 and corresponds to the hole 210 required to be formed on the beam 200.

[0035] The bottom holes 12 corresponding to the holes 210 required to be opened on the beam 200 means that the number of the bottom holes 12 is not less than the number of the holes 210 required to be opened on the beam 200, and when the beam 200 is correctly placed in the beam placement position 11, each hole 210 required to be opened on the beam 200 will have a corresponding bottom hole 12. Therefore, after the beam 200 is positioned by the positioning block 20, the positions of the holes 210 required to be opened on the beam 200 can be directly located by the bottom holes 12, and an operator can directly use a drilling device to drill holes in the beam 200 through the bottom holes 12 (for example, the beam 200 is placed and clamped on the front of the template body 10, and the drilling device drills the beam 200 through the bottom holes 12 from the back of the template body 10). This eliminates the need for complex manual marking, makes the operation simpler and more convenient, and reduces the skill requirements of the operator.

[0036] It is understood that in the prior art, manual marking is often used to drill holes. This method is labor-intensive, inefficient, inaccurate, and prone to errors, resulting in poor consistency in the drilled holes. However, with the stringer hole drilling template 100 provided in this embodiment, the stringer 200 only needs to be positioned on the template body 10, clamped, and then the holes 210 on the stringer 200 can be drilled. This method is simple to operate and easy to use, and its accuracy and consistency are far superior to manual marking, reducing labor intensity while also improving production efficiency.

[0037] The existing technology also uses mechanical processing to drill holes. Although this method has high precision, it is also costly and not worth the money for drilling holes in stringer parts. However, the stringer hole drilling template 100 provided in this embodiment can achieve high precision requirements while maintaining a certain level of production efficiency, and the cost is far lower than mechanical processing.

[0038] It is understandable that when the beams 200 to be manufactured have multiple models (for example, different lengths, or different numbers or positions of the holes 210), the beam hole template 100 can also be prepared in advance in multiple models (for example, different lengths, or different positions of the positioning blocks 20, and different positions of the bottom holes 12) to adapt to different models of the beams 200 for processing and use.

[0039] In one embodiment, the number of the bottom holes 12 provided on the template body 10 may be greater than the number of the holes 210 required to be provided on the beams 200, but it must be ensured that each hole 210 required to be provided on the beams 200 has a corresponding bottom hole 12. Thus, through this structure, one model of the beam hole template 100 can be adapted to process and use multiple models of the beams 200. Of course, in other embodiments, the number of the bottom holes 12 provided on the template body 10 may be the same as the number of the holes 210 required to be provided on the beams 200, and the bottom holes 12 are provided in a one-to-one correspondence with the holes 210 required to be provided on the beams 200. Thus, each model of the beam hole template 100 can be used to process and use a single model of the beams 200, thereby avoiding operator errors during the processing process.

[0040] Specifically, in one embodiment, the beam 200 is a “T”-shaped beam.

[0041] Preferably, in some embodiments, the beam hole template 100 further includes a drill sleeve 30, which is embedded and fixed in the bottom hole 12. Specifically, in one embodiment, the drill sleeve 30 is embedded in the bottom hole 12 and welded to the template body 10. In these embodiments, when the beam hole template 100 is used to drill holes in the beams 200, the drilling equipment drills holes from the back to the front through the guide holes of the drill sleeve 30. Of course, in other embodiments, for small-batch part production, it is also possible to adopt a method of not configuring a drill sleeve and directly drilling the beams 200 according to the bottom holes 12 on the template body 10.

[0042] Preferably, in some embodiments, the positioning block 20 is detachably connected to the template body 10, thereby facilitating adjustment of the position of the positioning block 20. The detachable connection between the positioning block 20 and the template body 10 facilitates disassembly and assembly and adjustment of the spacing between the positioning blocks 200 according to the different lengths of the beams 200, thereby enhancing flexibility. Specifically, in one embodiment, the positioning block 20 is detachably connected to the template body 10 via the bolts 40. Of course, in other embodiments, the connection between the positioning block 20 and the template body 10 may also be by welding, pin connection, or the like in addition to threaded connection.

[0043] Preferably, in some embodiments, the positioning block 20 includes a positioning block body 21 and abutting protrusions 22, and the positioning block body 21 is connected to the template body 10. The abutting protrusions 22 are provided at one end of the positioning block body 21, and the size of the connecting protrusions 22 is smaller than that of the positioning block body 21, and the connecting protrusions 22 are used to abut against the beams 200. That is to say, in these embodiments, the positioning block 20 specifically uses the smaller connecting protrusions 22 to abut against the beams 200, thereby reducing the contact area between the positioning block 20 and the beams 200. This structure can be regarded as converting line contact into point contact to a certain extent, reducing the influence of the machining error of the positioning block 20 itself and improving the positioning accuracy. Specifically, in one embodiment, the positioning block 20 as a whole adopts a "convex" structural design.

[0044] Preferably, in some embodiments, there are multiple (at least two) positioning blocks 20, each of which is divided into an end positioning block 201 and a side positioning block 202. Along the length of the template body 10, the end positioning block 201 is located on one side of the template body 10 and is used to abut the end of the beam 200. Along the width of the template body 10, the side positioning block 202 is located on one side of the template body 10 and is used to abut the side of the beam 200. The provision of the end positioning blocks 201 and the side positioning blocks 202 allows the two sides of the beam 200 to abut against each other, thereby more accurately positioning the beam 200. Preferably, in some embodiments, there are multiple (at least two) side positioning blocks 202, each spaced apart along the length of the template body 10. Specifically, in one embodiment, three positioning blocks 20 are provided, wherein one end positioning block 201 is provided and two side positioning blocks 202 are provided, and three-point contact positioning is performed to ensure that the beam 200 is positioned correctly on the template body 10. Specifically, as Figure 1 In the illustrated embodiment, the end positioning block 201 is located on the left side of the template body 10, corresponding to the center of the end surface of the beam 200. The positions of the two lateral positioning blocks 202 can be configured as needed based on the length of the beam 200. Of course, in other embodiments, the number and location of the positioning blocks 20 are not limited to three; multiple locations can also be configured based on actual needs.

[0045] Preferably, in some embodiments, the template body 10 is provided with scale lines 50. Along the length direction of the template body 10, the scale lines 50 are arranged relative to the end positioning block 201. By setting the scale lines 50, it is possible to detect whether the length of the beam 200 meets the requirements. For example, the left end of the beam 200 is placed against the end positioning block 201, and then observe whether the right end of the beam 200 exceeds the scale lines 50, so that it can be intuitively observed whether the length of the beam 200 meets the requirements. Preferably, in one embodiment, along the length direction of the template body 10, the scale lines 50 include a lower size deviation line, a theoretical size line, and an upper size deviation line arranged in sequence, so as to facilitate the detection of whether the length of the beam 200 meets the requirements.

[0046] Preferably, in some embodiments, a bending reinforcement structure 13 is provided at the end of the template body 10. The provision of the bending reinforcement structure 13 can significantly improve the overall rigidity and strength of the template body 10. Specifically, in one embodiment, along the width direction of the template body 10, the bending reinforcement structure is provided on the side of the template body 10 where the side positioning block 202 is not provided. More specifically, in one embodiment, the bending reinforcement structure 13 is a zigzag bending reinforcement structure. Of course, in other embodiments, the bending reinforcement structure 13 can also adopt other structural forms, such as an L-shaped reinforcement structure.

[0047] Among them, for the selection of the structural form of the template body 10, in addition to the use of an integral template, a segmented or combined template can also be used.

[0048] Considering the usage, cost and processability, the weight of the template body 10 should not be too large and must have a certain strength. Preferably, in some embodiments, the material of the template body 10 is ordinary carbon steel with a thickness of 2 to 3 mm.

[0049] In one embodiment, when manufacturing the beam hole template 100, first, the template body 100 in a flat state is designed according to the external structure and hole size requirements of the beam 200 to be processed, as well as the positioning hole requirements, that is, at least the holes on the beam 200 need to correspond one to one with the bottom holes 12 designed on the template body 10; then, the drill sleeve 30 is embedded in the bottom hole 12 of the template body 10 and welded and fixed; then, a circular bending structure is adopted on one side of the template body 10 in a flat state to improve its rigidity and strength; finally, the positioning block 20 is connected to the template body 10 by a screw.

[0050] In one embodiment, when drilling holes in the stringer 200, first, the straightened stringer 200 is placed on the stringer hole drilling template 100, and three-point contact positioning is completed by the positioning block 20 to ensure the correct position of the stringer 200 on the template body 10, and then the stringer 200 is clamped and fixed to the template body 10 using a clamp; then, according to the guide hole on the template body 10 inlaid with the drill sleeve 30, holes are drilled from the back to the front, first the positioning hole on the stringer 200 is drilled, the positioning pin is inserted, and then the remaining bottom holes on the stringer 200 are drilled; finally, the scale line 50 at the right end of the template body 10 is compared to check whether the length of the stringer 200 meets the requirements, and the above can complete the drilling and inspection work of the stringer 200.

[0051] The beam hole making template 100 integrates positioning, drilling and inspection functions, and has the characteristics of high efficiency, low cost, good precision, simple operation, easy use and good processing consistency.

[0052] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
