Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of alloy tools, and particularly relates to a keyhole drilling alloy tool with an anti-loosening structure. Background Art
[0002] An alloy tool is a tool made of different alloy elements or hard compounds, mainly used for cutting operations in the machining process. This kind of tool usually has high hardness and wear resistance, and can cut various materials more effectively. A keyhole drilling alloy tool is a special alloy tool, mainly used for drilling operations. Its design and manufacture are all aimed at the needs of drilling, and usually have high precision and durability. This kind of tool can drill precise holes in various materials, including metals, woods, plastics, etc. The manufacturing materials of the keyhole drilling alloy tool usually include hard elements such as tungsten carbide, titanium carbide, and cobalt carbide, which make the tool have high hardness and good cutting performance.
[0003] The existing keyhole drilling alloy tool usually consists of a drill bit, a drill rod and a drill shank. When in use, the drill shank is inserted into the drill chuck and the chuck clamps the drill shank by rotating the locking ring to complete the installation and fixation. However, the drill shank usually has a smooth surface structure, and the friction between the drill shank and the chuck is small, and the locking ring is prone to reverse rotation, resulting in easy rotation and loosening between the keyhole drill and the drill chuck during operation. Due to the instability between the drill bit and the chuck, the drilling position may deviate from the predetermined trajectory, affecting the accuracy of drilling. And if the keyhole drill falls off from the chuck during rotation, it may cause harm to the operator or damage the surrounding equipment. Summary of the Utility Model
[0004] The utility model aims to provide a keyhole drilling alloy tool with an anti-loosening structure to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A keyhole drilling alloy tool with an anti-loosening structure includes a keyhole drill and a drill chuck. The keyhole drill includes a drill bit, a drill rod and a drill shank. A plurality of clamping grooves are arranged on the surface of the drill shank in an annular array along the central axis. The drill chuck includes a rotating seat, a locking ring is rotatably arranged on the rotating seat, a plurality of chucks are movably arranged on the rotating seat, an included angle is arranged on one side of each chuck, and the included angle is clamped into the clamping groove. A sliding seat is arranged on one side of the rotating seat, a sliding rod is slidably arranged on the sliding seat, a stop block is arranged at the bottom of the sliding rod, an insertion rod is arranged at the bottom of the stop block, a spring is sleeved on the sliding rod, and a plurality of insertion slots are arranged at the top of the locking ring, and the insertion rod is inserted into the insertion slot.
[0007] Preferably, both ends of the spring are respectively abutted against the sliding seat and the stop block.
[0008] Preferably, a pull block is provided on the top of the slide rod.

[0010] Beneficial Effects
[0011] The above one or more technical solutions in the keyhole drill alloy tool with an anti-loosening structure provided by the embodiment of the utility model have at least one of the following technical effects:
[0012] The utility model adopts the above technical solution, and the angle card on one side of the chuck is embedded in the clamping groove. The chuck has a limiting effect when clamping the drill handle, so that the lockhole drill and the electric drill chuck will not rotate during use, and the insertion rod is inserted into the slot to limit the locking ring, avoiding the problem of the lockhole drill and the electric drill chuck being loose due to the reverse rotation of the locking ring, thereby improving the stability between the lockhole drill and the electric drill chuck, avoiding the problem that the drilling position may deviate from the predetermined trajectory due to rotational looseness, affecting the accuracy of drilling. It also avoids the problem that the lockhole drill falls off from the chuck during the rotation process, which may cause harm to the operator or damage to surrounding equipment, not only ensuring the use effect, but also taking into account safety.

[0022] As Figures 1-4 shown, it is a schematic structural diagram of a lock hole drilling alloy tool with an anti-loosening structure according to a preferred embodiment of the present utility model;
[0023] In this embodiment, a keyhole drill 1 and an electric drill chuck 2 are included. The keyhole drill 1 includes a drill bit 3, a drill rod 4, and a drill handle 5. The drill bit 3, the drill rod 4, and the drill handle 5 are integrally cast. The surface of the drill handle 5 is provided with a plurality of clamping grooves 6 in a circular array along the central axis. The electric drill chuck 2 includes a swivel seat 7. A locking ring 8 is rotatably provided on the swivel seat 7. A plurality of chucks 9 are movably provided on the swivel seat 7. An angle 10 is provided on one side of the chuck 9. The angle 10 is embedded in the clamping groove 6. The angle 10 is embedded in the clamping groove 6, which plays a limiting role between the chuck 9 and the drill handle 5, thereby preventing the drill handle 5 and the chuck 9 from slipping out. The rotating seat 7 has a sliding seat 11 welded on one side, and a sliding rod 12 is slidably provided on the sliding seat 11. The sliding rod 12 can slide up and down on the sliding seat 11, and a stopper 13 is integrally provided at the bottom of the sliding rod 12. A plug 14 is integrally provided at the bottom of the stopper 13. A spring 15 is sleeved on the sliding rod 12. A plurality of slots 16 are provided on the top of the locking ring 8. The plug 14 is inserted into the slots 16. The plug 14 is inserted into the slots 16 to limit the locking ring 8 and prevent the locking ring 8 from reversing, thereby preventing the lockhole drill 1 and the electric drill chuck 2 from loosening.
[0024] In this embodiment, the two ends of the spring 15 are respectively against the sliding seat 11 and the stopper 13, and the spring 15 provides elastic force to the insertion rod 14. The spring 15 pushes the stopper 13 so that the insertion rod 14 is inserted into the slot 16, and has a retaining force to prevent the insertion rod 14 from falling out of the slot 16.
[0025] In this embodiment, a pull block 17 is provided on the top of the slide rod 12. The operator can pull the pull block 17 to remove the insertion rod 14 from the slot 16, thereby canceling the limit on the locking ring 8, and then reverse the locking ring 8 to cancel the locking of the drill handle 5, and remove the keyhole drill 1 from the electric drill chuck 2.
[0026] In this embodiment, the inner wall of the locking ring 8 is threadedly connected to the outer sides of the plurality of chucks 9. By rotating the locking ring 8 to move the plurality of chucks 9 toward the middle, the drill shank 5 can be clamped (this structure is a prior art and will not be elaborated on herein).
