Description

Technical Field

[0001] The utility model relates to the technical field of drill bits, in particular to a drill bit structure capable of assisting positioning. Background Art

[0002] The drill bit is a tool widely used in many fields such as engineering construction, mechanical processing, geological exploration, etc., and plays an extremely important role. In mechanical processing, if the drilling depth of the bolt connection hole is too low, the anchoring length of the bolt will be insufficient, resulting in insufficient connection strength. During the operation of the equipment, it is easy to loosen or fall off, affecting the normal operation and service life of the equipment.

[0003] After searching, the Chinese patent with publication number CN217142444U discloses a drill bit structure with a positioning function. The utility model is provided with a first hollow cylinder, a first bearing, a second hollow cylinder, a hollow conical block, a first hollow block, an adjustment mechanism, a fixed block and a sliding hole. When the distance between the connecting block and the first hollow block reaches the maximum value, the rubber block is in close contact with the drill bit body through the connecting block and the flexible metal strip, and the first hollow cylinder is fixed on the drill bit body through the friction between the rubber block and the drill bit body. At this time, the drilling depth of the drill bit body is positioned by the hollow conical block, so that the user can accurately control the drilling depth.

[0004] However, the existing drill bit structure generally requires workers to intuitively feel the drilling depth and cannot preset the drilling depth. If the drilling depth is too low and cannot meet actual use requirements, re-drilling is required, which not only wastes previous drilling resources, but also increases the complexity and cost of construction. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above background technology, the prior art has the disadvantages of being unable to preset the drilling depth, resulting in drilling failure, and increasing the complexity and cost of construction.

[0006] The utility model discloses a drill bit structure capable of assisting positioning, comprising a drill bit body, a fixing rod being provided on the drill bit body, a sleeve being provided on the fixing rod, a limiting ring being provided on the sleeve, a limiting assembly being provided between the limiting ring and the fixing rod, a driving assembly being provided between the limiting ring and the sleeve, and a baffle being provided at the lower end of the sleeve.

[0007] Furthermore, the limiting assembly includes a fixing bolt, a fixing hole 1, and a fixing hole 2. The fixing hole 1 is arranged on the fixing rod, and the fixing hole 2 is arranged on the limiting ring. The fixing bolt passes through the fixing hole 1 and the fixing hole 2. The sleeve is provided with a guide groove, and the guide groove is slidingly arranged with the fixing bolt.

[0008] Furthermore, the drive assembly includes an adjusting ring, which is rotatably mounted on the limiting ring. A connecting block is mounted on the adjusting ring, which is threadedly connected to the sleeve. The length of the connecting block is greater than the horizontal length of the guide groove.

[0009] Furthermore, a driving rod is provided on the connecting block, and the driving rod is threadedly connected to the adjusting ring.

[0010] Furthermore, a spring is provided between the driving rod and the connecting block, the spring is sleeved on the driving rod, and two connecting blocks are symmetrically provided on the adjusting ring.

[0011] Furthermore, a plurality of the fixing holes 1 are provided, the spacings between the plurality of the fixing holes 1 are the same, and the size structure of the fixing hole 1 and the fixing hole 2 are the same.

[0012] Furthermore, a scale line is provided on one end of the limiting ring close to the adjusting ring, and a plurality of height holes are provided on the sleeve, and the plurality of height holes are evenly distributed.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model is provided with a fixing bolt, a sleeve, a limiting ring, an adjusting ring, a baffle and other components. During operation, the limiting ring can be restricted to the fixing rod through the fixing bolt component, and the adjusting ring component and the connecting plate component cooperate with each other to drive the adjusting ring to rotate, and the adjusting ring drives the connecting block to rotate accordingly, thereby driving the threaded sleeve to slide on the fixing rod, and the sleeve drives the baffle to follow the movement and stop after moving to a preset height, thereby adjusting the distance between the drill bit body and the baffle, achieving the effect of limiting the descent depth of the drill bit body, improving the drilling accuracy, and reducing the complexity and cost of construction.

[0015] 2. The utility model is provided with a driving rod, a spring, a connecting block, etc. During the working process, the driving rod component cooperates with the spring component to adjust the rotation of the driving rod component. The driving rod drives the connecting block to move with it through the spring, so that the connecting block is separated from the sleeve, thereby releasing the restriction on the sleeve, making it convenient to move the sleeve. By adjusting the driving rod to rotate in the reverse direction, the connecting block is threadedly connected to the sleeve, thereby limiting the position of the sleeve.

[0022] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0023] See also Figure 1 、 Figure 4 The drill bit structure with auxiliary positioning of the present invention includes a drill bit body 1, a fixing rod 2 is provided on the drill bit body 1, a sleeve 3 is provided on the fixing rod 2, a limiting ring 5 is provided on the sleeve 3, a limiting assembly is provided between the limiting ring 5 and the fixing rod 2, a driving assembly is provided between the limiting ring 5 and the sleeve 3, and a baffle 4 is provided at the lower end of the sleeve 3.

[0024] During operation, the sleeve 3 is controlled to move on the fixed rod 2 by the driving assembly, and the baffle 4 is driven to a preset height by the sleeve 3, thereby positioning the lowered position of the drill body 1, so that the drilling depth is within a reasonable range, avoiding increasing the complexity and cost of construction.

[0025] Combine Figure 1 、 Figure 2As shown, the limiting assembly includes a fixing bolt 10, a fixing hole 18, and a fixing hole 2 9. The fixing hole 18 is arranged on the fixing rod 2, and the fixing hole 2 9 is arranged on the limiting ring 5. The fixing bolt 10 passes through the fixing hole 18 and the fixing hole 2 9. The sleeve 3 is provided with a guide groove 11. The guide groove 11 and the fixing bolt 10 are slidingly arranged. During operation, when the sleeve 3 moves, the guide groove 11 slides on the fixing bolt 10, thereby limiting the moving direction of the sleeve 3 and preventing the sleeve 3 from rotating. The fixing bolt 10 is removed from the fixing rod 2, thereby releasing the restriction on the limiting ring 5 and the sleeve 3, and the limiting ring 5 and the sleeve 3 can be disassembled, and the limiting ring 5 and the sleeve 3 can be installed by reverse operation.

[0026] like Figure 1 、 Figure 3 As shown, the driving assembly includes an adjusting ring 6, which is rotatably installed on the limit ring 5. A connecting block 13 is installed on the adjusting ring 6, and the connecting block 13 is threadedly connected to the sleeve 3. The length of the connecting block 13 is greater than the horizontal plane length of the guide groove 11. When the position of the sleeve 3 needs to be adjusted, the staff drives the adjusting ring 6 to rotate, and the adjusting ring 6 drives the connecting block 13 to rotate accordingly. The threaded connection between the connecting block 13 and the sleeve 3 pushes the sleeve 3 to move, thereby adjusting the height of the sleeve 3. When the sleeve 3 moves, it drives the baffle 4 to move accordingly.

[0027] like Figure 3 As shown, a driving rod 15 is provided on the connecting block 13, and a sliding groove 14 is provided on the adjusting ring 6. The connecting block 13 and the sliding groove 14 are slidingly arranged, and the driving rod 15 is threadedly connected to the adjusting ring 6. When it is necessary to adjust the position of the baffle 4 over a long distance, the staff rotates the driving rod 15, and the driving rod 15 moves on the adjusting ring 6, and drives the connecting block 13 away from the sleeve 3, thereby releasing the restriction on the sleeve 3, and then drives the sleeve 3 to move. After reaching the preset position, the reverse operation is performed to limit the position of the sleeve 3.

[0028] A spring 16 is provided between the driving rod 15 and the connecting block 13. The spring 16 is sleeved on the driving rod 15. Two connecting blocks 13 are symmetrically provided on the adjusting ring 6. When the sleeve 3 is fixed, when the connecting block 13 cannot cooperate with the sleeve 3, the spring 16 applies a thrust to the connecting block 13, and then drives the adjusting ring 6 to rotate. When the connecting block 13 cooperates with the sleeve 3, one end of the driving rod 15 is rotated to support the connecting block 13.

[0029] like Figure 1 、 Figure 4 As shown, there are multiple fixing holes 8, the spacing between the multiple fixing holes 8 is the same, and the size structure between the fixing hole 8 and the fixing hole 2 9 is the same, which increases the limit height of the device and improves the application range of the device.

[0030] A scale line 7 is provided at one end of the limit ring 5 close to the adjustment ring 6, and a plurality of height holes 12 are provided on the sleeve 3. The plurality of height holes 12 are evenly distributed. The height holes 12 are convenient for the staff to calculate the approximate height, and the scale line 7 is used to help the staff calculate the distance between the two height holes 12, thereby improving the positioning accuracy of the device.

[0031] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
