Watchband drilling equipment with protection enclosed in a hole

Abstract

The invention discloses watchband drilling equipment with in-hole surrounding protection. The watchband drilling equipment structurally comprises a workbench, a stand column, an equipment body, a controller, a driving motor, a speed regulation knob, a blade stroke adjustment knob and a hole chapping prevention device. The watchband drilling equipment has the beneficial effects that: a hollow column is matched with a cutter tube, a downward blowing effect is performed on hole excess materials adhered to the inner side of the cutter tube after drilling, friction caused by the fact that the holeexcess materials scratches a watchband hole again along with the cutter tube due to the adhesion effect and enhanced chapping effect of the inner wall of the hole are avoided, the soft part of the inner side wall of the watchband hole after drilling is subjected to tightening treatment by means of an edge positioning mechanism, redundant burrs appearing on the inner side wall of the hole are further removed, therefore, the situation that when the watchband is pulled out, the force of the watchband and a downward compaction force of the cutter tube on the hole are in reverse action, the inner side wall of the hole is loose due to the reverse action force, redundant burrs are generated and unnecessary damage is caused to a hand back and the whole watchband due to the action of the burrs in the using process of the watchband is avoided.

Description

technical field [0001] The invention relates to the field of drilling equipment, more precisely, it is a wristband drilling equipment surrounded and protected in a hole. Background technique [0002] With the continuous development and evolution of the watch, it has become a kind of decoration while it is convenient for people to check the time. It is mainly worn on the wrist. In order to take care of the wearer's feel and the size of the wrist diameter, Usually the strap needs to be drilled, and when the leather strap is drilled, the excess strap material after drilling will adhere to the hole of the knife tube under the external force of downward extrusion, and In the process of withdrawing with it, due to the existing shaking, it is separated from the knife tube, thus falling off in the hole of the strap or having a frictional effect on it during the process of withdrawing with the knife tube, and the strap is squeezed downward. When drilling and cutting force, because i...

[0002] With the continuous development and evolution of the watch, it has become a kind of decoration while it is convenient for people to check the time. It is mainly worn on the wrist. In order to take care of the wearer's feel and the size of the wrist diameter, Usually the strap needs to be drilled, and when the leather strap is drilled, the excess strap material after drilling will adhere to the hole of the knife tube under the external force of downward extrusion, and In the process of withdrawing with it, due to the existing shaking, it is separated from the knife tube, thus falling off in the hole of the strap or having a frictional effect on it during the process of withdrawing with the knife tube, and the strap is squeezed downward. When drilling and cutting force, because it is a leather material, there will be redundant burrs and wires on the surface after cutting. At the same time, when the knife tube is recovered, the excess burrs and wires will be rubbed by the reaction force, and loosening will occur. , resulting in redundant burrs on the inner side of the strap hole after drilling, which will cause the strap hole to be more prone to cracking during later use
