a drilling tool

Abstract

The invention relates to a drilling tool, comprising a shank and a tool body which are connected to each other and extend around a central axis. The tool body includes a ring segment and a blade structure, the ring segment and the tool handle are connected and fixed, and the blade structure includes a Four evenly spaced circumferentially spaced cutting edges extend from the ring segment, the four cutting edges are arranged left-handed around the central axis, respectively extending from the circular ring segment away from the central axis and away from the shank, each cutting edge comprising a circumferential The outer surface of the blade and the inner surface of the blade are extended, the end of each blade away from the annular segment is provided with a leading edge extending radially outward from the outer surface of the blade, and the other end adjacent to the annular segment is provided with a front edge from the outer surface of the blade. The outer surface of the blade extends radially outward of the rear edge, and a hollow groove is formed between the front edge and the rear edge. The drilling tool of the invention is matched with the robot to form flexible drilling equipment, so as to meet the drilling requirements of different products, which can not only effectively save the factory site of the enterprise, but also reduce the development cost of the equipment.

Description

technical field [0001] The invention relates to the drilling of automotive exterior plastic parts, and more particularly relates to a drilling tool. Background technique [0002] Drilling operations are often involved in automotive exterior plastic parts, such as forming radar holes (holes for installing radars), cleaning holes (holes for installing automatic retractable water spray cleaning devices) and assembly holes ( holes for mounting trim), etc. In the prior art, these drilling operations are performed by a dedicated drilling machine, that is, one drilling machine is adapted to one type of product (workpiece). Obviously, this kind of "special purpose" equipment makes the enterprise site unsustainable, and the cost is difficult to control. [0003] In addition, existing special-purpose drilling machines inevitably have problems such as hole edge flanging, burrs and / or fuses, and can only meet the production requirements of process holes with low surface quality requir...

Problems solved by technology

Obviously, this kind of "special purpose" equipment makes the enterprise site unsustainable, and the cost is difficult to control

[0003] In addition, the existing special-purpose drilling machines inevitably have problems such as hole edge flanging, burrs and / or fuses, and can only meet the production requirements of process holes with low surface quality requirements or surface can be covered

Moreover, the existing special-purpose drilling machines have the problem of difficult waste disposal, which not only causes quality problems due to the friction between the drilling waste and the edge of the product hole due to the difficulty in separating the drilling waste, but more importantly, the subsequent drilling cannot be completed because the waste does not fall off on the tool. conduct
