Description

TECHNICAL FIELD

[0001] The utility model relates to drilling equipment technical field, specifically point to a kind of quick replacement drill device for drilling equipment. BACKGROUND

[0002] In modern mechanical processing industry, it is inevitable to punch the material, and the hole processed can not only play a connecting role, but also can play a role in reducing the weight of parts. However, after multiple punching operations, a new drill bit needs to be replaced to ensure the accuracy and efficiency of punching. Therefore, a quick replacement drill device for drilling equipment is proposed.

[0003] Chinese patent CN212917667U discloses a mechanical drilling device with quick drill replacement, which comprises a base, two L-shaped plates fixedly connected to the top end of the base, a fixed block fixedly installed at the top end of the L-shaped plate, two support plates fixedly connected to the top end of the base on both sides, a top plate fixedly connected to the top end of the support plate, and a clamping groove embeddedly connected to the bottom end of the top plate. In the utility model, the drill body is placed between the two peak-shaped plates, and the two peak-shaped plates can clamp the drill body through the force of the return spring. This facilitates the installation of drill bodies of different sizes. By turning the bolts into the interior of the sleeve and the peak-shaped plate, the peak-shaped plate can be fixed, which facilitates the fixation of the drill body. By turning the nut into the surface of the hand-tightening bolt, the hand-tightening bolt can be fixed, which prevents the hand-tightening bolt from loosening and causing the drill body to shake, thereby affecting the progress of the drilling work. However, there are still defects that can be improved.

[0004] 1. The utility model fixes the drill body through two peak-shaped plates and bolts, but it is worth noting that the fixation is achieved through the friction between the peak-shaped plate and the drill. During the punching operation, the drill body is constantly rotating, which can easily reduce the friction effect between the peak-shaped plate and the drill body, resulting in the inability to fix the drill body.

[0005] 2. In the utility model, two L-shaped plates and two fixed blocks are used to fix the parts to be drilled. However, during the drilling process, the rotation of the drill can cause the parts to shift. If the parts are not fixed, they can easily rotate with the drill, which can reduce the accuracy of the punching and change the position.
