[0002] Drilling machines are essential mechanical equipment in mechanical processing, and wrench-type drill chucks are one of the most commonly used tools for drilling machines. The wrench is a bevel gear with an extended lever arm, so during the tightening process, it can increase the torque input, so the clamping force of the chuck is large.

[0003] When the existing straight-grain drill chuck socket wrench is in use, the drill bit is clamped and removed by the small bevel gear of the wrench wheel engaging the bevel gear on the drill chuck outer jacket to drive the nut jaw of the clamping jaw to extend and retract. After the drill chuck and the wrench wheel are used in production for a period of time, the bevel gear on the drill chuck outer jacket and the small bevel gear on the wrench wheel will wear out, making it difficult to clamp the drill bit. Therefore, we propose a straight-grain drill chuck wrench. Utility Model Content

[0026] See also Figure 1-3 The utility model provides a technical solution: a straight drill chuck wrench, comprising:

[0027] A straight drill chuck sleeve 1, wherein a mounting cavity 8 is provided inside the straight drill chuck sleeve 1;

[0028] A drill bit disassembly structure, which is located on the straight drill chuck sleeve 1;

[0029] The drill bit disassembly structure includes a straight drill chuck 7, a wrench 2 and a top plate 3. The straight drill chuck 7 is installed in a mounting cavity 8. A plurality of top grooves 6 are provided on the outer surface of the straight drill chuck 7. A rotating groove 5 connected to the interior of the mounting cavity 8 is provided on the side wall of the straight drill chuck sleeve 1. The top plate 3 is rotatably connected to the interior of the rotating groove 5. The wrench 2 is fixedly connected to the top plate 3, and the top plate 3 is respectively adapted to the plurality of top grooves 6.

[0030] The drill bit disassembly structure also includes a fixed column 9 and a rotating cylinder 13. The rotating cylinder 13 is fixedly connected to one side of the straight drill chuck sleeve 1. A mounting hole 15 is provided on the side of the rotating cylinder 13 away from the straight drill chuck sleeve 1. The fixed column 9 is fixedly connected to the side of the straight drill chuck 7 close to the rotating cylinder 13. The fixed column 9 is slidably connected to the mounting hole 15.

[0031] A fixing plate 10 is fixedly connected to the side of the rotating cylinder 13 away from the straight drill chuck sleeve 1, and a pull rod 11 is slidably connected inside the fixing plate 10. A fixing hole 14 is opened on the outer surface of the fixing column 9, one end of the pull rod 11 is plugged into the fixing hole 14, a spring 12 is fixedly sleeved on the outer surface of the pull rod 11, one end of the spring 12 is fixedly connected to the fixing plate 10, and the end of the spring 12 away from the fixing plate 10 is fixedly connected to the pull rod 11.

[0032] A protective sleeve 4 is fixedly sleeved on the outer surface of the wrench 2 .

[0033] Furthermore, when using the device, the operator inserts the fixing column 9 into the mounting hole 15, and then, by pulling the pull rod 11, the pull rod 11 will stretch the spring 12. When the straight drill chuck 7 is placed, the operator loosens the pull rod 11, and the pull rod 11 will reset under the support of the spring 12 and be plugged into the adjusted fixing hole 14, thereby facilitating the limit fixation of the straight drill chuck 7, thereby facilitating the rapid installation of the straight drill chuck 7. When disassembling the drill bit, the operator sleeves the straight drill chuck 7 on the outside of the drill bit so that the teeth on the straight drill chuck 7 engage with the teeth on the drill bit. Then, the operator rotates the wrench 2, and the wrench 2 drives the top plate 3 to rotate. Under the clamping connection between the top plate 3 and the corresponding top groove 6, the top plate 3 can adapt to straight drill chucks 7 of various specifications, so that the straight drill chuck 7 is installed on the drill bit, thereby facilitating the straight drill chuck 7 to disassemble the drill bit.

[0034] Through the cooperation of the straight drill chuck 7, the wrench 2, the top plate 3, the fixed column 9, the rotating cylinder 13, the fixed plate 10, the pull rod 11 and the spring 12, the straight drill chuck 7 can mesh with the teeth on the drill bit, and then the straight drill chuck 7 can be evenly stressed when rotating, so that the drill bit can be easily and quickly loaded and unloaded, and the installed drill bit is firm and reliable, avoiding the problem that the drill bit cannot be clamped tightly due to the wear of the small bevel gear of the original drill chuck wrench during the processing, thereby affecting the drilling accuracy, and further making the drill bit clamped more tightly after installation.

[0035] By providing the protective cover 4, the protective cover 4 can protect the operator's hands and also improve the anti-slip property of the wrench 2, thereby improving the practicability of the device.

[0036] Working principle: the operator inserts the fixing column 9 into the mounting hole 15, and then, by pulling the pull rod 11, the pull rod 11 will stretch the spring 12. When the straight drill chuck 7 is placed, the operator releases the pull rod 11, and the pull rod 11 will be reset under the support of the spring 12 and plugged into the adjusted fixing hole 14, so as to facilitate the limiting fixation of the straight drill chuck 7, thereby facilitating the rapid installation of the straight drill chuck 7. When disassembling the drill bit, the operator sleeves the straight drill chuck 7 on the outside of the drill bit so that the teeth on the straight drill chuck 7 are engaged with the teeth on the drill bit. Then, the operator turns the wrench 2, and the wrench 2 drives the top plate 3 to rotate. Under the clamping connection between the top plate 3 and the corresponding top groove 6, the straight drill chuck 7 is installed on the drill bit, thereby facilitating the straight drill chuck 7 to disassemble the drill bit.

[0037] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
