Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, completeSite preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments, notIn the case of conflict, the feature in embodiment and embodiment in the application can be mutually combined, and below with reference to the accompanying drawings and be tiedEmbodiment is closed to describe the present invention in detail.
As shown in figure 1, a kind of drilling Double-side rounding compound tool, including handle of a knife 1, chamfering blade 2 and drill plate 3, instituteIt is hollow-core construction to state handle of a knife 1, and the lower end of handle of a knife 1 is provided with one and goes out the edge of a knife 11, and the chamfering blade 2 is arranged in handle of a knife 1, rose reamerPiece 2 includes knife bar 21 and cutter head 22, and the top of knife bar 21 is movably fixed to the upper end of handle of a knife 1, knife by an adjustment bolt 23The middle part of bar 21 passes through a shop bolt 24, and knife bar 21 can be that fulcrum be rotated with shop bolt 24, and cutter head 22 is from going out knifeMouth 11 stretches out the perisporiums of handle of a knife 1, and the drill plate 3 is fixed on the bottom of handle of a knife 1 by a fastening bolt 31.
The handle of a knife 1 is cylinder, and multiple screws (not shown) are provided with handle of a knife 1, and screw is used to wear for bolt admittedlyCross to fix blade.
The cutter head 22 is Double-side rounding cutter head, the burr of hole two and chamfering can be disposably removed during work, such as Fig. 6 institutesShow, an elastic device 25 is provided with the handle of a knife 1, and the one end of elastic device 25 is fixed on the inwall of handle of a knife 1, and the other end is heldAt the back side of cutter head 22, elastic device 25 can ensure that cutter head 22, with certain support strength, can also be adjusted in processingCutter head 22 stretches out the length of the edge of a knife 11, when need adjust cutter head 22 from go out the edge of a knife 11 stretch out handle of a knife 1 apart from when, such as to inward turningWhen turning adjustment bolt 23, adjustment bolt 23 drives the upper end of knife bar 21 to move inward, and knife bar 21 is clicked through with shop bolt 24 for branchRow rotation, cutter head 22 become big from the distance for going out the edge of a knife 11 and stretching out handle of a knife 1, on the contrary cutter head 22 from go out the edge of a knife 11 stretch out handle of a knife 1 away fromIt is small from adding and subtracting, i.e., meet the drilling demand of different requirements using lever principle.
The chamfering blade 2 is used to remove flash removed and chamfering, as shown in Fig. 2 the middle part of the knife bar 21 is provided with a positioningGroove 212, locating slot 212 are snapped onto in shop bolt 24 so that knife bar 21 can be that fulcrum carries out upper backspin with shop bolt 24Transfer is dynamic, as shown in figure 3, the adjustment bolt 23 includes swingle 231 and the both ends of swingle 231 raise up the screw thread to be formedPlatform 232, helicitic texture is provided with screw thread platform 232, and swingle 231 passes through the perisporium of handle of a knife 1, the week of screw thread platform 232 and handle of a knife 1Wall is threadedly coupled, and the region between two screw thread platforms 232 forms holding end 233, the top insertion holding end 233 of the knife bar 21Interior, further, the top of the knife bar 21, which raises up, to be formed one and holds block 211, is held block 211 and is embedded in holding end 233,By rotating swingle 232, it is that fulcrum is rotated that screw thread platform 232, which drives and holds block 211 along shop bolt 24, so that cutter head 22From the perisporium for going out the stretching handle of a knife 1 of the edge of a knife 11, so as to adjust the length of the stretching of cutter head 22.
As shown in Figure 4, Figure 5, the shop bolt 24 includes nipple 241 and locating rod 242, the nipple241 are connected to the end of locating rod 242, and nipple 241 and the junction formation one of locating rod 242 hold face 243, and screw thread connectsFirst 241 are threadedly coupled with handle of a knife 1, and locating rod 242 is inserted into handle of a knife 1 and passes through the locating slot 212 of knife bar 21, and locating slot212 hold with holding face 243, therefore by rotating nipple 241, hold face 243 and promote knife bar 21 to be finely adjusted so as to realThe angle of cutter head 22 is now adjusted, is easy to different size of chamfered.
The drill plate 3 is bored using magic or indexable drill.
When this drilling tool is processed, drill plate 3 is rotated to lower feeding, and drill plate 3 contacts workpiece and starts to bore firstHole, when drill plate 3 is fed to chamfering blade 2, the inside edge of drilling of the chamfering blade 2 to workpiece carries out chamfered,Drilling and chamfering are disposably completed so as to realize, process is simplified, improves processing efficiency, reduce manufacturing cost.In use, cutter head 22 wears, and now adjusts adjustment bolt 23, and regulation cutter head 22 stretches out handle of a knife 1 from the edge of a knife 11 is gone outDistance, you can continue to use, at the same can also according to the size of the chamfering of workpiece, adjust shop bolt 24 can adjustAdjust the angle of cutter head 22.
The present invention can once complete drilling and fall in one step process by setting chamfering blade and drill plateAngle operates, while chamfering blade uses lever construction principle, has regulatory function, can control chamfering angle size, so as to simplifyProcess, processing efficiency is improved, reduce manufacturing cost.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hairThe equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necksDomain, it is included within the scope of the present invention.
