Description

Technical Field

[0001] The utility model particularly relates to a twist drill with a stable structure. Background Art

[0002] A twist drill is a tool that forms a circular hole in a workpiece by rotating it relative to a fixed axis. It is named because its chip groove is spirally shaped like a twist.

[0003] Currently, at the initial stage of the twist drill's circular hole drilling process, the surface of the object being drilled is smooth and the worker has no fulcrum. This may result in inaccurate drilling positions and require the worker to spend more time and labor costs. Utility Model Content

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a twist drill with a stable structure, comprising a drill body, a stabilizing frame and a guide assembly, wherein the drill body comprises a round rod portion and a drill head portion, and the stabilizing frame is arranged outside the round rod portion;

[0006] As the drill head rotates, the drill head drills into the object, and the stabilizing frame can slide along the length direction of the round rod portion through the guide assembly to support the drill body.

[0007] Preferably, the stabilizing frame includes a fixed disk sleeved on the outside of the round rod portion, and the outside of the fixed disk is connected to a rotating ring through a rotating block.

[0008] Preferably, a sliding groove is provided around the outer side of the fixed disk and the rotating ring, a slider is provided in the sliding groove, and the slider extends out of the sliding groove and is connected to the rotating block.

[0009] Preferably, three stabilizing legs are arranged at equal intervals around the lower surface of the rotating ring, and the stabilizing legs are connected to the rotating block through a connecting block.

[0010] Preferably, the guide assembly includes guide strips that are equidistantly arranged around the outer side of the round rod portion.

[0011] Preferably, three fixing plates are provided around the outer side of the round rod portion, and each of the fixing plates is respectively provided between every two guide bars.

[0012] Preferably, a spring is provided on the upper surface of the fixing plate, and one end of the spring away from the fixing plate is connected to the stabilizing frame.

[0013] The technical effects and advantages of the utility model are as follows: the twist drill with a stable structure, after the drill head is aligned with the desired drilling position, the stabilizing legs are respectively in contact with a circle of outer surfaces of the hole to be drilled, and the drill head and the round rod part are supported by the stabilizing legs. As the drilling power device drives the drill head to rotate, the drill head will gradually enter the object to be drilled. At this time, the slider slides in the slide groove, and the rotating block rotates between the rotating ring and the fixed disk, so that the stabilizing legs remain stable, and the drill head moves more smoothly through the guidance of the guide bar, which reduces the labor cost and time cost of the staff supporting the drill bit to drill holes, and improves the drilling efficiency.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] In order to reduce the cost of drilling, refer to Figure 1 、 Figure 2 and Figure 3The tool 2 is fixed on the workbench 1 and the guide bar 9 is provided with a screw thread, and the tool 2 is fixed on the workbench 1 and the guide bar 9 is provided with a screw thread, and the tool 2 is fixed on the workbench 1 and the guide bar 9 is provided with a screw thread, and the tool 2 is fixed on the workbench 1 and the guide bar 9 is provided with a screw thread, and the tool 2 is fixed on the workbench 1 and the guide bar 9 is provided with a screw thread, and the tool 2 is fixed on the workbench 1 and the guide bar 9 is provided with a screw thread, and the tool 2 is fixed on the workbench 1 and the guide bar 9 is provided with a screw thread, and the tool 2 is fixed on the workbench 1 and the guide bar 9 is provided with a screw thread, and the tool 2 is fixed on the workbench 1 and the guide bar 9 is provided with a screw thread, and the tool

[0021] In order to improve the drilling efficiency, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the stabilizing frame includes a fixed disk 3 that is sleeved on the outside of the round rod 1. The outside of the fixed disk 3 is connected to a rotating ring 5 through a rotating block 4. A sliding groove 6 is opened around the outside of the fixed disk 3 and the rotating ring 5. A slider is set in the sliding groove 6. The slider extends to the outside of the sliding groove 6 and is connected to the rotating block 4. When the driving unit drives the round rod 1 to rotate, the drill head 2 rotates accordingly, causing the fixed disk 3 to rotate. The slider slides in the sliding groove 6, driving the rotating block 4 to rotate between the fixed disk 3 and the rotating ring 5, so that the stabilizing legs 7 can be unaffected by the rotation of the drill head 2 and remain stably fixed around the periphery of the drilled hole. Three stabilizing legs 7 are equidistantly arranged around the lower surface of the rotating ring 5. The stabilizing legs 7 are connected to the rotating block 4 through a connecting block 8. The drill head 2 is stabilized by the stabilizing legs 7, and there is no need for manual support of the drill head 2, which improves stability while reducing labor costs.

[0022] Furthermore, the guide assembly includes guide bars 9 arranged at equal intervals around the outer side of the round rod portion 1. Three fixed plates 10 are provided around the outer side of the round rod portion 1, and each fixed plate 10 is respectively arranged between every two guide bars 9. A spring 11 is provided on the upper surface of the fixed plate 10. The spring 11 is connected to a stabilizing frame at one end away from the fixed plate 10. When the drill head 2 rotates, the drill head 2 will gradually enter the object to be drilled. At this time, the round rod portion 1 can follow the guide bar 9 and descend, allowing the stabilizing frame to maintain its original position. During the drilling process, the descent of the drill head 2 will cause the spring 11 to be stretched. After drilling is completed, the spring 11 deforms and can pull the drill head 2, allowing the staff to expend less effort when removing the drill head 2. A square groove compatible with the guide bar 9 is penetrated on the surface of the fixed disk 3. The end of the guide bar 9 is provided with a limited end to prevent the round rod portion 1 from derailing from the fixed disk 3.

[0023] When in use, first align the drill head 2 with the desired drilling position, and then the stabilizing legs 7 are respectively in contact with the outer surface of the hole to be drilled, and the drill head 2 and the round rod part 1 are supported by the stabilizing legs 7. As the drilling power device drives the drill head 2 to rotate, the drill head 2 will gradually enter the object to be drilled. At this time, the slider slides in the slide groove 6, and the rotating block 4 rotates between the rotating ring 5 and the fixed disk 3, and the drill head 2 is moved by the guidance of the guide bar 9.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
