Description

Technical Field

[0001] This utility model belongs to the field of civil engineering, specifically a drilling positioning device for civil engineering. Background Technology

[0002] In civil engineering construction, it is often necessary to drill holes in various types of boards (such as wooden formwork, steel formwork, or precast concrete slabs) to meet the needs of bolt fixing, splicing installation, or pipeline laying. The drilling quality of these boards directly affects the accuracy of subsequent construction.

[0003] However, current drilling operations on sheet metal generally rely on workers repeatedly measuring the surface of the sheet metal with a ruler and then marking the drilling positions point by point with a marker. This method is not only inefficient, but manual marking is also susceptible to human error (such as line-of-sight deviation or uneven marking pressure), resulting in insufficient hole position accuracy. Especially when the sheet metal needs to be drilled with multiple sets of holes, particularly when multiple holes are required to be evenly distributed, repeated measurements and markings can easily produce cumulative errors, causing inconsistent hole spacing and seriously affecting the fit and construction quality of subsequent assembly.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a drilling positioning device for civil engineering. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a drilling positioning device for civil engineering.

[0006] A drilling positioning device for civil engineering includes a positioning plate with a notch at the top and a U-shaped mounting block inside the notch. A positioning mechanism for drilling and positioning a plate is slidably disposed on the inner side of the mounting block.

[0007] The positioning mechanism includes a scale that is slidably disposed inside the mounting block, a U-shaped positioning block that is slidably disposed on the scale, a connecting block that is disposed on the rear side of the positioning block, a positioning hole that is provided on the connecting block, a connecting member that is disposed on the positioning block, and a positioning component that cooperates with the positioning hole for equidistant positioning.

[0008] Preferably, the upper part of the mounting block is threaded with a bolt, the bottom end of which penetrates the mounting block and abuts against the upper part of the scale.

[0009] Preferably, the scale is provided with grooves on both the front and rear sides, and the inner front and rear ends of the positioning block are provided with sliders that cooperate with the grooves, and the sliders are located in the grooves. The front side of the positioning block is provided with a bolt 2, and the rear end of the bolt 2 passes through the inner side of the positioning block and abuts against the outer side of the scale.

[0010] Preferably, the connector includes a movable plate that slides through the rear side of the positioning block, and a rectangular block is provided on one side of the movable plate.

[0011] Preferably, the positioning component includes a top block disposed on the upper rear side of the rectangular block, a connecting rod slidably passing through the top block, a positioning ball disposed at the bottom of the connecting rod, a spring sleeved on the outer side of the connecting rod, and the two ends of the spring being connected to the connecting rod and the upper part of the top block, respectively.

[0012] Preferably, the upper part of the positioning block is provided with a bolt three, and the bottom end of the bolt three abuts against the upper part of the moving plate.

[0013] Preferably, the upper part of the positioning block has a rectangular opening, and an indicator block is provided inside the rectangular opening and on the front side of the rectangular block.

[0014] Preferably, the inner vertical section of the positioning plate is on the same vertical plane as the right side of the mounting block.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model replaces the manual marking method of holding a ruler and marking with a pen by using the positioning plate and mounting block as a reference positioning, the positioning block and the scale as a combination, and the precise alignment of the indicator block. This avoids human errors such as line of sight deviation and uneven marking force, and ensures the positioning accuracy of a single hole.

[0016] 2. This utility model, through the cooperation of connectors and positioning components, allows for the rapid and precise continuous positioning and drilling of multiple equidistant holes on a sheet material when drilling multiple holes at equal intervals. By pushing the moving plate to bring the positioning ball and the positioning hole of the connecting block to the preset hole distance, the elastic locking design of the positioning ball enables the continuous positioning and drilling of multiple equidistant holes on the sheet material quickly and accurately. The entire process does not require workers to mark the hole positions on the sheet material sequentially, which avoids the cumulative error of manual marking and ensures the consistency of hole spacing, greatly improving the efficiency and accuracy of equidistant drilling.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a drilling positioning device for civil engineering, including a positioning plate 1. The upper part of the positioning plate 1 has a notch, and a U-shaped mounting block 2 is provided in the notch. A positioning mechanism 3 for drilling positioning of the plate is slidably provided on the inner side of the mounting block 2. The positioning mechanism 3 includes a scale 31 slidably provided on the inner side of the mounting block 2. A U-shaped positioning block 32 is slidably provided on the scale 31. A connecting block 33 is provided on the rear side of the positioning block 32. A positioning hole 34 is provided on the connecting block 33. A connecting member 35 is provided on the positioning block 32. A positioning component 36 is provided on the connecting member 35 to cooperate with the positioning hole 34 for equidistant positioning.

[0021] refer to Figure 1 The upper part of the mounting block 2 is threaded with a bolt 4. The bottom end of the bolt 4 passes through the mounting block 2 and abuts against the upper part of the scale 31.

[0022] refer to Figure 3 The inner vertical section of the positioning plate 1 is on the same vertical plane as the right side of the mounting block 2.

[0023] When drilling holes in the board, the positioning plate 1 is attached to the board, and then the scale 31 on the inner side of the mounting block 2 is slid and adjusted according to the range of holes to be drilled on the board, so that it covers the area of ​​the board to be drilled. Then, the scale 31 is locked on the mounting block 2 by bolt 4 to prevent it from shifting in subsequent operations.

[0024] refer to Figure 1 and Figure 2 The scale 31 has grooves 5 on both the front and back sides. The positioning block 32 has sliders 6 at both the front and back ends on the inner side, which cooperate with the grooves 5. The sliders 6 are located in the grooves 5. The positioning block 32 has a bolt 7 threaded on the front side. The rear end of the bolt 7 passes through the inner side of the positioning block 32 and abuts against the outer side of the scale 31.

[0025] refer to Figure 2 The connector 35 includes a movable plate 351 that slides through the rear side of the positioning block 32, and a rectangular block 352 is provided on one side of the movable plate 351.

[0026] refer to Figure 2 and Figure 3 The upper part of the positioning block 32 has a rectangular opening, and an indicator block 9 is provided inside the rectangular opening and on the front side of the rectangular block 352.

[0027] In this process, after the positioning block 32 is installed on the scale 31 by the cooperation of the slider 6 and the groove 5, the positioning block 32 can be moved to the position on the board where a hole needs to be drilled according to the indicator block 9 on the positioning block 32. Then, the positioning block 32 is locked on the scale 31 by the bolt 2 7. At this time, the drill bit on the drilling machine can pass through the positioning hole 34 on the connecting block 33 to drill the board accurately. There is no need for the staff to mark the board with a marker pen, which improves the drilling efficiency of the board.

[0028] refer to Figure 2 The positioning component 36 includes a top block 361 disposed on the upper rear side of the rectangular block 352, a connecting rod 362 slidably passing through the top block 361, a positioning ball 363 disposed at the bottom of the connecting rod 362, and a spring 364 sleeved on the outer side of the connecting rod 362, with the two ends of the spring 364 connected to the upper part of the connecting rod 362 and the top block 361 respectively.

[0029] refer to Figure 2 The upper part of the positioning block 32 is threaded with a bolt 38, and the bottom end of the bolt 38 abuts against the upper part of the moving plate 351.

[0030] When multiple equally spaced holes need to be drilled on the board, the movable plate 351 can be pulled to move the rectangular block 352 to a suitable position according to the distance between two adjacent holes. At this time, the distance between the positioning ball 363 and the positioning hole 34 is the distance between two adjacent holes to be drilled. Then, the bolt 38 is tightened to lock the movable plate 351. At this time, the outer side of the positioning ball 363 contacts the upper part of the board.

[0031] After drilling the first hole, the worker loosens bolt 7 to release the locking of positioning block 32. Then, the worker moves positioning block 32, causing rectangular block 352 to move synchronously. When positioning ball 363 moves to the position of the drilled hole, the elastic force of spring 364 causes positioning ball 363 to embed into the drilled hole, forming a precise lock. At this time, positioning hole 34 on connecting block 33 is exactly in the accurate position for the next hole. After tightening bolt 7 to fix positioning block 32, the drilling operation for the second hole can begin (e.g., ...). Figure 4As shown in the figure, repeating the above steps can quickly and accurately complete the continuous positioning drilling of multiple equidistant holes on the board. The whole process does not require the staff to mark the hole positions on the board in sequence, which avoids the cumulative error of manual marking and ensures the consistency of hole spacing, greatly improving the efficiency and accuracy of equidistant drilling.

[0032] Working principle: When drilling and positioning the board, the positioning plate 1 provides a reference by adhering to the edge of the board. Then, the scale 31 on the inner side of the sliding mounting block 2 is slidable to cover the required drilling range. The scale 31 is fixed by tightening the bolt 4. The positioning block 32 is then installed on the scale 31 by using the cooperation of the sliding groove 5 and the slider 6. When the indicator block 9 is aligned with the target scale, the positioning block 32 is fixed by tightening the bolt 7. At this time, the drilling tool can be used to guide the drilling through the positioning hole 34 on the connecting block 33 without manual marking.

[0033] When multiple equally spaced holes need to be drilled on a sheet material, first slide the movable plate 351 behind the positioning block 32, and adjust the distance between the positioning ball 363 and the positioning hole 34 of the connecting block 33 to the preset hole distance using the indicator block 9. Tighten the bolt 38 to lock the movable plate 351. After drilling the first hole, loosen the bolt 27 to slide the positioning block 32, so that the positioning ball 363 on the top block 361 behind the rectangular block 352 is embedded in the drilled hole under the action of the spring 364 to form a locking position. At this time, the positioning hole 34 is aligned with the next hole position. After tightening the bolt 27 to fix it, drilling can continue. By repeating this cycle, multiple equally spaced holes can be drilled quickly and accurately on the sheet material, which avoids manual marking errors and ensures the consistency of hole distance, greatly improving drilling efficiency and accuracy.
