Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices that are easy to position, in particular to a drilling device that is easy to position. Background Art

[0002] A drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It is also called a drilling machine, a punching machine, a hole-drilling machine, a through-hole machine, etc. It achieves the desired effect by drilling holes in precision parts. There are semi-automatic drilling machines and fully automatic drilling machines. With the increase in human resource costs, most companies consider fully automatic drilling machines as their development direction. With the development of the times and the improvement of the drilling technology of automatic drilling machines, the use of fully automatic drilling machines for drilling holes in various hardware molds, watch straps, and jewelry has obvious advantages.

[0003] After searching, a Chinese patent with publication number CN218694065U discloses a drilling device that is easy to position.

[0004] The above solution solves the problem that this device can limit the position of the workpiece being processed from multiple angles to ensure its stability during the drilling process. However, this device needs to replace the workpiece clamp and drill it multiple times when drilling holes at different positions on the workpiece, which easily causes a waste of drilling time. In addition, there are no auxiliary positioning parts during the drilling process, which easily causes a slight deviation in the position of the drill hole during drilling, thereby reducing the accuracy of the drilling.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
