Abstract
Description
Technical Field
[0001] This utility model relates to the field of drilling rig drill bit technology, specifically a drilling rig drill bit with positioning function. Background Technology
[0002] A drill bit is a commonly used drilling tool, typically mounted on a drilling rig. It creates holes in materials by rotating and applying pressure. This tool is widely used in construction, mining, manufacturing, and many other fields, and is an indispensable piece of equipment in engineering construction and material processing.
[0003] However, traditional drilling rigs suffer from the drawback of inaccurate positioning during drilling. Due to the lack of an effective positioning mechanism, operators often struggle to accurately control the drilling depth, potentially leading to holes that are too deep or too shallow, thus affecting project quality and material utilization. Furthermore, the inability to precisely position the drill bit can increase operational difficulty and safety risks, causing inconvenience to construction.
[0004] Therefore, we propose a drilling bit with positioning function. Utility Model Content
[0005] The purpose of this invention is to provide a drill bit with a positioning function to address the aforementioned shortcomings in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a drill bit body, and the drill bit with positioning function further includes:
[0007] By installing bearings to set up a sliding rail on the drill bit body and a positioning rod set on the sliding rail, when drilling through the drill bit body, the end of the positioning rod abuts against the drilling plane;
[0008] The positioning mechanism and the abutment rod installed in the sliding rail through the positioning mechanism, when the drill bit body is drilling and the positioning rod slides along the sliding rail and abuts against the abutment rod, the positioning mechanism limits the positioning rod, thereby realizing the positioning action of the drill bit body when drilling.
[0009] As a further description of the above technical solution: the positioning mechanism includes a limiting slider that is slidably disposed in the sliding track and a blocking plate that is fixed on the limiting slider. The abutment rod is movably inserted into the limiting slider, and a horizontal plate is fixedly disposed on the abutment rod. The horizontal plate is connected to the blocking plate through a spring column, and the horizontal plate overlaps the upper surface of the limiting slider.
[0010] As a further description of the above technical solution: the positioning mechanism also includes an insert rod disposed on the end of the contact rod, and a hollow tube rotatably disposed on the top surface of the baffle plate. The inner wall surface of the hollow tube is provided with a spiral groove, and a pulley is slidably installed in the spiral groove. The surface of the insert rod inserted into the hollow tube is connected to the pulley, and a prompting turntable is fixedly disposed after the insert rod passes through the baffle plate and the hollow tube.
[0011] As a further description of the above technical solution: the blocking plate is equipped with fastening bolts, and the fastening bolts pass through the blocking plate and abut against the surface of the sliding track.
[0012] As a further description of the above technical solution: the diameter of the hole through which the insertion rod passes through the barrier plate is smaller than the diameter of the contact rod.
[0013] As a further description of the above technical solution: when the horizontal plate overlaps the surface of the limiting slider, the length of the bottom of the abutment rod protruding from the bottom surface of the limiting slider is the same as the distance between the top port of the abutment rod and the bottom surface of the blocking plate.
[0014] As a further description of the above technical solution: the bottom surface of the abutment rod is provided with a protrusion.
[0015] In the above technical solution, the drilling bit with positioning function provided by this utility model has the following beneficial effects:
[0016] Precise positioning: Through the cooperation of the sliding rail, positioning rod, and positioning mechanism, this drill bit can achieve precise positioning of the drilling depth. When the positioning rod abuts against the contact rod, the positioning mechanism limits the positioning rod, thereby ensuring that the drill bit stops drilling when it reaches the predetermined depth.
[0017] Improved drilling accuracy: Due to its precise positioning, this drill bit reduces errors and improves drilling accuracy during the drilling process. This is especially important for projects requiring high-precision drilling.
[0018] Improve drilling efficiency: Workers can preset the drilling depth, and when the drill bit reaches that depth, the positioning mechanism will automatically stop, eliminating the need for continuous monitoring and adjustment by workers, thereby improving drilling efficiency.
[0019] Safety alert function: Through the cooperation of the insertion rod, hollow tube and pulley, when the drill bit approaches the predetermined depth, the indicator turntable will rotate to remind the staff to pay attention, thereby avoiding excessive force that could damage the drill bit or cause safety hazards.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] Please see Figure 1-3 This utility model embodiment provides a technical solution: including a drill bit body 1, which is mounted on a drilling rig and drills holes through the drilling rig. The drill bit with positioning function also includes:
[0028] By installing bearing 2, a sliding rail 3 is set on the drill bit body 1, and a positioning rod 4 is set on the sliding rail 3. When drilling through the drill bit body 1, the end of the positioning rod 4 abuts against the drilling plane. When drilling through the drill bit body 1, the drill bit body 1 is gradually inserted into the drilled hole. At this time, the positioning rod 4 is pressed and slides upward in the sliding rail 3.
[0029] Since the drilling bit with positioning function also includes a positioning mechanism and an abutment rod 13 installed in the sliding rail 3 through the positioning mechanism, when the drilling bit body 1 performs drilling operation and the positioning rod 4 slides along the sliding rail 3 and abuts against the abutment rod 13, the positioning mechanism limits the positioning rod 4 to realize the positioning action of the drilling bit body 1 when drilling.
[0030] In one embodiment of this utility model, the positioning mechanism includes a limiting slider 5 slidably disposed in the sliding track 3 and a blocking plate 11 fixed on the limiting slider 5. The abutment rod 13 is movably inserted into the limiting slider 5, and a horizontal plate 6 is fixedly disposed on the abutment rod 13. The horizontal plate 6 is connected to the blocking plate 11 through a spring column 12, and the horizontal plate 6 overlaps the upper surface of the limiting slider 5. As the drilling deepens, the positioning rod 4 is pressed and gradually moves upward in the sliding track 3 until it abuts against the bottom end of the abutment rod 13 and pushes the abutment rod 13 upward. At this time, the spring column 12 is compressed and deformed until the top end of the abutment rod 13 abuts against the surface of the blocking plate 11. Since the blocking plate 11 is equipped with a fastening bolt 8, and the fastening bolt 8 passes through the blocking plate 11 and abuts against the surface of the sliding track 3, the position of the blocking plate 11 is locked, thereby fixing the positioning rod 4. At this time, the positioning rod 4 cannot move, and the drill bit body 1 cannot continue drilling, thereby achieving the positioning of the drilling depth.
[0031] It should be noted that loosening the fastening bolt 8 allows the limiting slider 5 and the blocking plate 11 to slide within the limiting track. Scale lines can be set on the surface of the limiting track housing. When the horizontal plate 6 overlaps the surface of the limiting slider 5, the length of the bottom of the abutment rod 13 protruding from the bottom surface of the limiting slider 5 is the same as the distance between the top end of the abutment rod 13 and the bottom surface of the blocking plate 11. Thus, after the positioning rod 4 contacts the bottom protrusion of the abutment rod 13, it pushes the abutment rod 13 upwards until the bottom side of the abutment rod 13 is fully inserted into the limiting slider 5. At this point, the bottom of the abutment rod 13 will just abut against the bottom surface of the blocking plate 11, and the positioning rod 4 is fixed, thus fixing the drilling depth. Therefore, when adjusting the drilling depth, it is only necessary to align the bottom surface of the limiting slider 5 with the depth to be drilled on the scale line.
[0032] When drilling with the drill bit body 1, just before the drilling depth reaches the set dimension, to alert the operator that they can slightly relax their grip and prevent damage to the drill bit body 1 or safety hazards caused by excessive force when the positioning rod 4 is fixed, the spring column 12 is compressed and deformed when the abutment rod 13 is pressed and moved, generating greater pressure to alert the operator. To further enhance this effect, the positioning mechanism also includes an insert rod 7 at the end of the abutment rod 13 and a hollow tube 10 rotatably mounted on the top surface of the baffle plate 11. The inner wall surface of the hollow tube 10 has a spiral groove 15, and a pulley 14 is slidably installed in the spiral groove 15. The surface of the insert rod 7 inserted into the hollow tube 10 is connected to the pulley 14, and the insert rod 7 passes through the baffle plate 11 and the hollow tube 10. A prompting turntable is fixedly installed at the rear. When the contact rod 13 abuts against the bottom surface of the baffle plate 11, the contact rod 13 cannot pass through because the diameter of the hole through which the insertion rod 7 passes in the baffle plate 11 is smaller than the diameter of the contact rod 13. The positioning rod 4 is limited, while the insertion rod 7 moves upward, causing relative movement between the insertion rod 7 and the hollow tube 10. At this time, the pulley 14 slides in the spiral groove 15, causing the insertion rod 7 to generate a rotational force, thereby causing the prompting shaft 9 at the top to rotate. When the operator sees the prompt rotating, they can know that the drilling depth is about to be reached and can slightly relax the force to prevent safety hazards and prevent the drill bit body 1 from breaking. When the prompting shaft 9 rotates, in order to amplify the prompting effect, a whistle hole can be opened on the prompting shaft 9 to produce a whistle sound when rotating, thereby improving the prompting effect.
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
