Description
Technical field
The utility model relates to a kind of non-blade reamers, and in particular to a kind of machining non-blade reamer.
Background technique
In drill rod manufacturing, it is related to the machine in hard alloy hole mostly in its technical process of all kinds of drilling tools of production
Tool processing, it is contemplated that interchangeability and production efficiency when the volume procurement of hard alloy, the control of cost, inserted tooth etc. are many
Factor, usually needs to process that many apertures are consistent, dimensional tolerance range is small, table in same batch or multiple batches of similar specification product
The more demanding hard alloy hole of surface roughness, and what we often selected is that structure is simple, manufacturing cost is low, processing dimension is steady
The non-blade reamer fixed, machined surface quality is high is in the finishing for carrying out hard alloy hole.
In use, the cutting tip that discovery non-blade reamer is contacted with hole bottom will appear because of cooling insufficient temperature mistake
It is high and the phenomenon that fail in advance, cause its service life shorter, need to often replace cutter, therefore production efficiency is not high.
Utility model content
Technical problem to be solved in the utility model be the cutting tip that non-blade reamer is contacted with hole bottom will appear because
Cooling deficiency temperature is excessively high and the phenomenon that earlier failure occurs, and it is an object of the present invention to provide a kind of machining non-blade reamer, solves nothing
The cutting tip that sword reamer is contacted with hole bottom will appear the excessively high problem of cooling insufficient temperature.
The utility model is achieved through the following technical solutions:
A kind of machining non-blade reamer, including coaxial knife handle, cutter head, knife handle is sequentially connected with cutter head, and cutter head is length
The cutter head of cube shape is mounted on hard metal tip in four lateral edges of cutter head, axially offers inside knife handle
The second channel through cutter head, first passage and are axially offered through the first passage of knife handle, inside cutter head
The connection of two channels.
The utility model increases first passage, second on the basis of original non-blade reamer on reamer knife handle, cutter head
Channel, cutting fluid reaches reamer cutter head by first passage, second channel and carries out cooling profit when hole machined in carrying out to workpiece
It is sliding, solve the problems, such as original non-blade reamer premature failure due to cooling deficiency temperature is excessively high in inner hole of workpiece processing.
The first passage and second channel being interconnected in the utility model are cooling ducts inside reamer, cutting fluid from
Cooling duct enters inside reamer and sprays from cutter head, has achieved the effect that cooling reamer；Hard metal tip in the utility model
As the main cutting tip of cutter head, the machining to inner hole of workpiece is mainly realized in a manner of extruding, since it has
The advantages that structure is simple, manufacturing cost is low, processing dimension is stable, machined surface quality is high, is usually used in higher in machining
The interior hole machined of precision；The cutter head hardness of conventional non-blade reamer is low, and service life is short, facilitates to extend knife using hard metal tip
The service life of head.The utility model reamer compared with former non-blade reamer, every utilization rate cutter at least improve 10 times with
On, so that the cost of charp tool is drastically decreased, because cutter utilization rate improves, the replacement number of cutter is reduced therewith,
Therefore production efficiency also improves.

Still keep lower temperature, the cooling effect having had, solve the problems, such as cutter head be unable to get uniformly, be fully cooled.
Knife handle is detachably connected with cutter head.Cutter head wears the abrasion greater than knife handle in use, existing reamer
Knife handle and cutter head are integral types, after cutter head is seriously worn, need replacing entire reamer, and the equipment cost of consuming is big,
Knife handle is caused largely to waste；Knife handle is connect with cutter head using dismountable mode by the utility model, when cutter head is seriously ground
After damage, cutter head is directly replaced.
Knife handle offers the jack coaxial with knife handle close to the side of cutter head, and cutter head is connected with and inserts close to one end of knife handle
Hole matches the connecting shaft of connection, is provided with the threaded hole being mutually matched on knife handle, connecting shaft.By the jack of connecting shaft insertion knife handle
Interior, knife handle is aligned with the threaded hole in connecting shaft and together with being inserted into bolt into realizing consolidating for connecting shaft and knife handle in threaded hole
Fixed, to realize being fixedly connected for cutter head and knife handle, fixation is easy to disassemble, easy to use.
Hard metal tip is fastened on by welding in the lateral edges of cutter head.
The utility model compared with prior art, has the following advantages and benefits:
1, cutting fluid passes through first to a kind of machining non-blade reamer of the utility model when hole machined in carrying out to workpiece
Channel, second channel reach reamer cutter head and carry out cooling and lubricating, solve original non-blade reamer in inner hole of workpiece processing because cold
Insufficient temperature is excessively high and the problem of premature failure；
2, hard metal tip is main as the main cutting tip of cutter head in a kind of machining non-blade reamer of the utility model
The machining to inner hole of workpiece is realized in a manner of extruding, since it is simple with structure, manufacturing cost is low, processing ruler
Very little stabilization, the advantages that machined surface quality is high, are usually used in the interior hole machined of degree of precision in machining；
3, a kind of machining non-blade reamer of the utility model shortens heat exchanger time of the cutting fluid in flow process,
After cutting fluid is sprayed from cutter head head, the temperature of cutting fluid still keeps lower temperature, and the cooling effect having had solves knife
Head be unable to get uniformly, the problem of being fully cooled.
