Abstract
The utility model relates to a machining cutter. The back segment of the machining functional segment of the machining cutter is a hole drilling portion with a predetermined length. The hole drilling portion is abutted with a screw thread tapping portion whose external diameter is larger than the predetermined size of the hole drilling portion. The length of the screw thread tapping portion is a little longer than the length of the hole drilling portion. The cone shaped drilling end of the hole drilling portion is provided with more than two (including two) chip guide slots which helically extend to a connecting segment, so that a cutting portion is formed on the drilling end. Therefore, the hole drilling portion can complete the program of hole drilling and screw thread tapping within one hole drilling procedure under the driving of the machining cutter.
Description
Technical field
The utility model is about a kind of process tool, refers to a kind of process tool design that is exclusively used in thin plate boring and tapping especially.
Background technology
Need based on the combination of workplace, people often establish screw on the thin plate workpiece, and using provides the bolt spiral shell to establish wherein to be locked, and therefore, screw is an important structure for the combination of thin plate workpiece.
At present on the thin plate workpiece, establishing a screw, in order to being provided, bolt or screw spiral shell establish wherein, the practice that people use always, shown in Fig. 4 A, B, be to be drilled with a perforation (41) prior to the last preposition place of workpiece (40) with the driven drill bit of drilling machine (50), again so that tap (60) is changed drill bit (50), with tap (50) this perforation (41) is attacked and to establish screw thread, the side becomes a screw (42) with screw thread.
Established in the operating process of a screw as can be seen in workpiece by aforementioned: it needs earlier with bit bore, change the tap screw thread again, because of changeing of machining tool, and the standby time of the tap screw thread that changes the outfit after the boring, for the processing operation, unhandy problem is arranged, and the operator is for the screw of predetermined each size that is drilled with on the workpiece, at least essential drill bit and tap of preparing a correspondingly-sized on the instrument cost, has the more problem of cost.
The utility model content
Main purpose of the present utility model is to be to provide a kind of process tool that has boring and tapping function concurrently, and is aforementioned when establishing screw on workpiece in order to solve, operation inconvenience, and the higher problem of instrument cost.
For reaching above-mentioned purpose, technical scheme that the utility model proposes is that to make the elaboration section latter end of this process tool be the bore portion of a predetermined length, this bore portion is in abutting connection with the tap portion of an external diameter greater than bore portion preliminary dimension, this tap minister Du Lve is longer than bore portion length, more than the coniform drilling end of this bore portion is established two roads (containing), be spirally extended to the dregs guiding groove of linkage section, and make on the drilling end and form blade.
In other words, for reaching purpose of the present invention, the invention provides a kind of process tool, it is characterized in that: described process tool comprises that an elaboration section and is in order to provide machining machine and tool affixed linkage section, this elaboration section latter end is the bore portion of a predetermined length, this bore portion is in abutting connection with the tap portion of an external diameter greater than bore portion preliminary dimension, this tap portion external diameter is about the bore portion external diameter and adds two times of depth of thread sums, tap minister Du Lve is longer than bore portion length, this bore portion is established the dregs guiding groove that is spirally extended to linkage section more than two roads (containing) in its coniform drilling end, and make on the drilling end and form blade, constitute a process tool that has boring and tapping function concurrently.
The utility model is with the design of technique scheme, with attainable effect be: process tool of the present utility model can be under machining machine and tool drives, in drilling program, workpiece is carried out the continue step of tapping of boring earlier, have and shorten the process time of on workpiece, establishing screw, and can be single process tool replace the summation of a drill bit and a tap, reduce the acquisition cost of instrument.
That is to say, by learning in the above explanation: process tool of the present utility model is under machining machine and tool drives, can be in drilling program, workpiece is carried out the continue step of tapping of boring earlier, finish the procedure of processing of establishing screw on the workpiece, need not the trival matters of the instrument of changing the outfit, can effectively shorten the processing activity duration; On the other hand, the utility model process tool can solid memder replaces the use by a drill bit and a tap, its unit price is less than the summation of drill bit and tap, thus can reduce the acquisition cost of instrument, for people provide one to have more design handy, practical function.

The specific embodiment
The specific embodiment of relevant the utility model process tool please cooperate and consult shown in Figure 1ly, and this oval shaft-like process tool (1) comprises that an elaboration section (10) and is in order to provide the affixed linkage section of machining machine and tool (20), wherein:
This elaboration section (10) latter end is the bore portion (11) of a predetermined length, this bore portion (11) locates to be the tap portion (12) of external diameter greater than bore portion (11) preliminary dimension in abutting connection with linkage section (20), aforesaid tap portion (12) external diameter is about bore portion (11) external diameter and adds two times depth of thread sum, length slightly is longer than bore portion (11) length, tap portion (12) can be towards bore portion (11) length dimension gradually-reducing shape in abutting connection with the predetermined length of bore portion (11) again, the kenel that the depth of thread is gradually shallow, this bore portion (11) end is a coniform drilling end (111) again, and this drilling end (111) is established the dregs guiding groove (13) that is spirally extended to linkage section (20) more than two roads (containing) certainly, and makes drilling end (111) form blade (112).
The utility model is when using, as Fig. 3 A, shown in the B, be to select the process tool of bore portion (11) length for use greater than workpiece (30) thickness of slab according to the thickness of slab of thin plate workpiece (30), inferior linkage section with this process tool (1) (20) is arranged in the chuck of machining machine and tool, make this process tool (1) can be machining machine and tool and drive rotation, afterwards, be connected to workpiece (30) pre-position with this process tool that is driven in rotation (1) drilling end (111) tip, promptly the blade (112) by turn carries out drilling on workpiece (30), workpiece (30) can be discharged via spiral dregs guiding groove (13) by the detritus of drilling, so, promptly pierce gradually in the workpiece (30) with bore portion (11), form a perforation (31) through workpiece (30) back fully until bore portion (11), make the tap portion (12) of process tool (1) continue again and this perforation (31) is carried out the step of tapping, treat that tap portion (12) runs through wherein fully, promptly form a screw (32) with internal thread, afterwards, make this machining machine and tool reverse drive process tool (1) again, allow process tool (1) recess workpiece (30).
