Description

Technical Field

[0001] The utility model relates to the technical field related to drilling devices, in particular to a fixed-point drilling device. Background Art

[0002] When drilling holes in plates, metal parts, etc., a drilling device is needed. The drilling device is a general term for equipment used to process holes in solid materials. It is widely used in building beams, plates, columns, walls, etc. When drilling, in order to ensure the accuracy of the drilling, the drilling point needs to be fixed to ensure the fixed-point drilling of the material.

[0003] The prior art has the following deficiencies: In the prior art, the publication number CN219151625U states that “by providing a clamping assembly, the rotation of the second servo motor drives the second screw to rotate, thereby driving the first threaded block and the second threaded block to move left and right, thereby driving the clamping block to move left and right, and automatically clamping the object. The fixed-point drilling auxiliary device does not need to be manually adjusted, which greatly reduces the time required for fixing doors and windows”;

[0004] However, the prior art requires multiple auxiliary adjustments of the material when drilling and positioning, which is rather troublesome. At the same time, there is a height difference between the drill bit position and the material. When positioning, the drill bit height needs to be adjusted down, which is rather troublesome and affects the efficient drilling of the material. In addition, when drilling, the drill bit is prone to shaking, offset, etc. due to the applied force, which affects the accuracy of drilling. Utility Model Content
