Description
Technical field
The utility model relates to drill bit manufacture field, is specifically related to a kind of left-handed reamer easily fixed and control.
Background technology
Drill bit is the indispensable instrument of the every profession and trade borings such as building, machining, the drill bit of prior art is generally dextrorotation, the processing of right direction rotary drilling is carried out on workpiece, but the anti-wear performance that apex point is bored in dextrorotation is very poor, and chip removal is slower in the process of punching, the heat produced is large, and heat radiation is slow, has had a strong impact on the service life of apex point.And the working portion of normal drill bit and drillstock are formed in one, when working portion is damaged, just need this drill bit entirety to give up, waste a lot of useful resources.And in the field of reamer, reamer adopts one-body molded, namely the corresponding corresponding reamer in the hole of diameter is determined, thus in order to get the hole of different-diameter, different reamers need be processed, no matter this aspect all increases for the producer or user the waste of resource, when user needs out using, with the reamer of different-diameter, therefore need also be unfavorable for the use of user.Due to the smooth in appearance of drillstock, be also unfavorable for being fixed in mechanical workpieces, be unfavorable for setting up parts again on drillstock, in use easily produce danger.
Therefore, the problems referred to above should be paid attention to and the problem solved in the design and use process of drill bit.
Utility model content
For above-mentioned Problems existing, the utility model provides a kind of left-handed reamer.
Technical solution of the present utility model is: a kind of left-handed reamer, comprise drillstock and drill body, described drill body is positioned at the top of described drillstock, and described drill body comprises cutting portion and reamer as working portion, and described cutting portion and described reamer all offer left-handed snail groove;
Described reamer is between described cutting portion and described drillstock, the top of described reamer and described drillstock all offers a hollow circular hole, each described hollow circular-hole internal-wall is all carved with the first screw thread, the tail end of described cutting portion is carved with second screw thread that can be fitted together to described reamer top first screw thread, described reamer tail end is also carved with second screw thread that can be fitted together to described drillstock top first screw thread, the tail end of described cutting portion inserts in the hollow circular hole of described reamer, the tail end of described reamer inserts in the hollow circular hole of described drillstock, described cutting portion, described reamer and described drillstock realize overall package by the first screw thread and the chimeric of the second screw thread.
Further improvement of the utility model is: the tail end outer ring of described drillstock is carved with the 3rd screw thread.
Further improvement of the utility model is: the reamer can choosing different-diameter according to the size of reaming.
Further improvement of the utility model is: the direction of rotation that described reamer is arranged on described cutting portion is consistent with the direction of rotation that described drillstock is arranged in described reamer.
A kind of left-handed reamer of the utility model, the size of holing as required chooses the reamer of different-diameter, chimeric with the first screw thread of reamer top endoporus by the second screw thread of cutting portion tail end, cutting portion is screwed in reamer inside, be tightened in reamer, by the second screw thread of reamer tail end, reamer is screwed in the hollow circular hole at drillstock top, thus it is overall to form drill bit.The 3rd screw thread being positioned at drillstock afterbody can screw in mechanical workpieces, thus makes drill bit be fixed in mechanical workpieces, facilitates mechanical workpieces to the operation of drill bit.Also when drillstock length is inadequate, the thick drillstock of the 3rd screw thread tabling on an energy and drillstock outer ring can be installed at drillstock end again, to meet the demand extended drillstock.When cutting portion or reamer abrasion damage, can be disassembled, new cutting portion or reamer be changed and just can.
The beneficial effects of the utility model are: the drill bit of the utility model design processes left-handed blade and left-handed snail groove on cutting portion and reamer, drill bit can be made operationally to cut while will the chip produced be cut, release forward, front clearance, thus keep the clean of machined surface, be convenient to see processing line clearly, processing carried out smoothly, effectively improves the efficiency of work.Cutting portion, reamer and drillstock is adopted to adopt screw thread chimeric versions thereof to be connected, when parts damages, these parts can be disassembled, change new parts to continue to use, save a large amount of costs, reamer can be chosen according to perforate size, the demand that the hole meeting arbitrary diameter need punch.All direction of rotation are all consistent when mounted, and during bit operation, integral-rotation direction is also consistent with the direction of rotation of installing, and avoid in working angles, drill bit all parts unclamps.Drillstock end is provided with the 3rd screw thread can be fixed in mechanical workpieces by drill bit, also can install another section of drillstock to meet the demand of jumping chisel handle.
