Description

A kind of special groove profile entirety taper reamer
Technical field
The utility model relates to a kind of taper reamer, specially a kind of special groove profile entirety taper reamer.
Background technique
Reamer is that have one or more cutters tooth, to cut off the rotary cutter of machined hole surface sheet metal, reamer Rotation finishing tool with straight sword or helical edges.Reamer lacks its requirement on machining accuracy because of cutting output and is usually above drill bit, can It is worked with being manually operated or being mounted on drilling machine, and reamer is for the hole after drilling (or reaming) processing on ream workpiece, it is main It is the finishing for hole and semi-finished cutter if reducing the roughness on its surface to improve the machining accuracy in hole, The general very little of machining allowance.
The taper reamer used in the factory of workpieces processing at present is useless in hole in the dressing process of drilling or reaming Bits can be drawn along the path of reamer reaming, and what it is due to processing is mostly steely material, and scrap is not easy to disconnect, due to spiral The arrangement at angle, groove profile and rear placement of foot is unreasonable, and the pass of finishing is more coarse, the requirement of precision is not achieved, therefore we are right This makes improvement, proposes a kind of special groove profile entirety taper reamer.
Utility model content
It is not easy the more coarse defect of the pass for disconnecting and modifying to solve scrap of the existing technology, this is practical new Type provides a kind of special groove profile entirety taper reamer.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
A kind of special groove profile entirety taper reamer of the utility model, including knife handle, one end of the knife handle are fixed with hinge Knife cutter head, the reamer cutter head are equipped with land, and several chip-breakers are offered on the land, and one end of the land is equipped with cone Sword is spent, one end of the taper sword is equipped with end sword, and the other end of the knife handle offers reference center hole.
Further, the side on the surface of the reamer cutter head offers cutter groove.
Further, reamer cutter head one end is equipped with chamfering blades.
Further, it is one such to be set as 1:6,1:8 and 1:10 for the taper ratio of the taper sword.
Further, the land is respectively equipped with first rear foot and second rear foot.
Compared with prior art, the utility model has the following beneficial effects: this kind of special groove profile entirety taper reamer, leads to The chip-breaker offered on taper sword is crossed, the cutting of reamer workpiece scrap when modifying pass is facilitated;By cutting with scissors Knife cutter head one end is equipped with chamfering blades, can not have to taking away reamer into replacement chamfering tool from tool apron, reduce process in this way Step increases the efficiency of work;By land be respectively equipped with first rear foot and second rear foot and with the helical angle of reamer, protect The finish of pass has been demonstrate,proved, the coarse rough phenomenon of pass will not occur;Reference center is offered by one end in knife handle Hole, facilitate reamer to knife.
Detailed description of the invention

Fig. 2 is a kind of one of side structure schematic diagram of special groove profile entirety taper reamer of the utility model.
In figure: 1, knife handle;2, taper sword;3, chamfering blades;4, cutter groove;5, chip-breaker;6, reference center hole;7, land;8, Hold sword;9, reamer cutter head.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of special groove profile entirety taper reamer, including knife handle 1, one end of knife handle 1 are fixed with hinge Knife cutter head 9, reamer cutter head 9 are equipped with land 7, and several chip-breakers 5 are offered on land 7, and one end of land 7 is equipped with taper sword 2, One end of taper sword 2 is equipped with end sword 8, and the other end of knife handle 1 offers reference center hole 6.
Wherein, the side on the surface of reamer cutter head 9 offers cutter groove 4, facilitates the withdrawing of reamer cutter head 9.
Wherein, the two sides of 9 one end of reamer cutter head are equipped with chamfering blades 3, can not have to replacement cutter and directly adjust cutter Angle can chamfering, increase working efficiency.
Wherein, it is one such to be set as 1:6,1:8 and 1:10 for the taper ratio of taper sword 2, and reamer cutter head 9 is facilitated to modify hole Type and reaming.
Wherein, land 7 is respectively equipped with first rear foot and second rear foot, guarantees the finish of pass.
It should be noted that the utility model is that a kind of special groove profile entirety taper reamer when specific operation consolidates reamer It is scheduled on tool apron, with reference center hole 6 after to knife, starts repair hole or reaming, be offered on land 7 The arrangement of the position of chip-breaker 5 and taper sword 2, facilitates reamer to cut off workpiece scrap when modifying pass, will not influence reamer Work can not have to taking away reamer into replacement chamfering tool from tool apron, just in the chamfering blades 3 that 9 one end of reamer cutter head is equipped with Chamfering can be carried out to workpiece, reduce extra process, increase the working efficiency of reamer;Land 7 is respectively equipped with first rear foot Helical angle with second rear foot and with reamer cutter head 9, it is ensured that pass roughness will not occur for the finish of pass excessive The phenomenon that.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
