Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drill chuck locking devices, and relates to a clamping tool for manual drill keys. Background Technology
[0002] In the field of machining, when changing drill bits in a manual drill, a drill key is used to tighten or loosen the drill chuck. The operator needs to apply pressure with one hand to maintain the engagement between the drill key and the chuck groove, while simultaneously rotating the drill with the other hand. This can easily lead to insufficient axial pressure, causing slippage between the drill key and the chuck teeth, resulting in the drill bit not being clamped tightly or difficult to remove. Therefore, many operators use hammers or other objects to strike the drill key to tighten or loosen the drill bit, which affects the lifespan of the drill key. Utility Model Content
[0003] Utility Model Purpose To address the aforementioned problems in the existing technology, this utility model provides a clamping tool for manual drill keys. Addressing the issue of the small handle of manual drill keys making it difficult to install and remove the drill chuck, this tool is designed to clamp the handle of the manual drill key, thereby extending the tightening lever arm and improving the portability and reliability of installing and removing the drill chuck. This clamping tool has a simple structure, strong versatility, and low cost, making it easy to promote and widely apply among various aircraft manufacturers.
[0004] Technical solution A clamping tool for a manual drill key includes a clamping rod (1), a locking ring (2), and a locking bolt (3). The working end of the clamping rod (1) is provided with a clamping groove (4), which is used to clamp the handle of the drill key. The locking ring (2) is sleeved on the clamping rod (1) and locked by the locking bolt (3).
[0005] Furthermore, the non-working end of the clamping rod (1) is provided with a weight-reducing hole for reducing the weight of the clamping tool.
[0006] Furthermore, the non-working end of the clamping rod (1) is knurled to prevent slippage.
[0007] Furthermore, the locking ring (2) is provided with an internal thread for engaging with the external thread of the locking bolt (3) to achieve thread locking.
[0008] Furthermore, the length of the clamping groove (4) should be greater than the length of the handle of the drill key.
[0009] Furthermore, the width of the clamping groove (4) should be greater than the diameter of the drill key handle.
[0010] Technical effect The present invention provides a clamping tool for a manual drill key. Through the above technical solution, the tightening arm of the manual drill key is extended, improving the portability and reliability of the manual drill chuck loading and unloading. It is highly versatile, with a simple and ingenious structure, low production cost, and easy to promote and apply in various aircraft manufacturers. Attached Figure Description
