Abstract
The utility model discloses a machine clip-on spotfacing tool which comprises a tool body and a blade; the tool body adopts a hollow cylindrical structure, and the inner diameter of one end at which the blade is mounted is smaller than that of the other end of the tool body; the outer edge at the end where the blade is mounted on the tool body takes an involute structure; a clipping step used for mounting the blade is arranged on the tool body, and a screw hole used for fixing the blade is formed in the side wall of the clipping step; a through hole used for penetrating a blade fastening bolt is formed on the blade; the blade is fixed in the clipping step on the tool body; a connecting screw hole used for connecting the spotfacing tool and a rotating shank into a whole is formed on the pipe wall of the tool body; and a positioning key way is arranged on the pipe wall of the tool body. The machine clip-on spotfacing tool has the advantages of reasonable structure, convenient use, long service life, high operating efficiency and the like, can reduce the production cost of the spotfacing tool and the consumption of raw materials, improve the production efficiency, is convenient for chip removal and also can facilitate the replacement of the blade to meet different processing demands; and more importantly, the blade can be conveniently switched to meet different demands.
Description
Technical field
The utility model relates to the cutting-tool engineering field, is specifically related to a kind of clip type countersink.
Background technology
Along with the develop rapidly of society's science and technology, lathe obtains application more and more widely in China's mechanical processing industry.Simultaneously, solve the insoluble many processing difficult problems of machine tool, improved machining accuracy and production efficiency, processing technology and Tool Design have been proposed many new, higher requirements.For these advanced equipment are played a role better, must address these problems.
Tubular workpiece in the existing boiler for producing industry needs ream to go out many stepped holes so that the connection between the pipe fitting on it.In the boiler processing industry, when processing step hole, the special-purpose ream head that makes for a long time is that a kind of monoblock type high-speed tool steel (high-speed steel) is made both at home and abroad, and the price comparison of high-speed steel is expensive, if whole cutter hub is all made of high-speed tool steel, not only involve great expense, and efficient is not high, because the hardness of high-speed tool steel only is that using soon, cutting edge is is just worn and torn about the HPC60 degree, thereby cause very big waste, and the roughness height in the hole that goes out of ream.The more important thing is that when the needs ream went out difform ripple oral pore, the switching of different countersinks is inconvenience very.
In addition, the front end of existing countersink cutter hub (end of blade is installed) mostly is the hollow cylinder shape structure, though this structure can guarantee the intensity of countersink, yet is cost to sacrifice cost of manufacture and rapidoprint simultaneously, and has brought the problem of chip removal inconvenience.
The utility model content
The purpose of this utility model is to overcome above-mentioned technical deficiency, a kind of clip type countersinks rational in infrastructure, easy to use, advantages such as cost is low, the life-span is long, operating efficiency height that have are provided, this clip type countersink can not only reduce the production cost and the raw material consumption of countersink, enhance productivity, chip removal is convenient, can also change blade easily and satisfy different processing needs.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of clip type countersink is provided, comprises cutter hub and blade; It is characterized in that: described cutter hub is the hollow cylinder body structure, and the internal diameter of an end that is used to install blade is less than the other end; The outward flange that is used to install an end of blade on the described cutter hub is involute shape structure; Described cutter hub is provided with the screens step that is used to install blade, is provided with the screw that is used for fixing blade in the sidewall of screens step; Described blade is provided with the through hole that is used to wear the blade fastening bolt; Described blade is fixed in the screens step on the cutter hub by the blade fastening bolt; The tube wall of described cutter hub is provided with and is used for being connected screw with what countersink and rotation handle of a knife connected as one; The tube wall of described cutter hub is provided with positioning spline.
According to clip type countersink provided by the utility model, it is characterized in that: described blade adopts carbide alloy, pottery or man-made polycrystalline diamond to make.
Advantages such as that clip type countersink provided by the utility model has is rational in infrastructure, easy to use, life-span length, operating efficiency height, can reduce the production cost and the raw material consumption of countersink, enhance productivity, chip removal is convenient, can also change blade easily and satisfy different processing needs.What is more important can be switched blade easily to satisfy different needs.

Wherein, 1, cutter hub; 101, positioning spline; 102, connect screw; 2, blade; 3, blade fastening bolt.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in FIG., this clip type countersink comprises cutter hub 1 and blade 2; It is characterized in that: described cutter hub 1 is the hollow cylinder body structure, and the internal diameter of an end that is used to install blade 2 is less than the other end; The outward flange that is used to install an end of blade 2 on the described cutter hub 1 is involute shape structure; Described cutter hub 1 is provided with the screens step that is used to install blade 2, is provided with the screw that is used for fixing blade 2 in the sidewall of screens step; Described blade 2 is provided with the through hole that is used to wear blade fastening bolt 3; Described blade 2 is fixed in the screens step on the cutter hub 1 by blade fastening bolt 3; The tube wall of described cutter hub 1 is provided with and is used for being connected screw 102 with what countersink and rotation handle of a knife connected as one; The tube wall of described cutter hub 1 is provided with positioning spline 101.Described blade 2 adopts carbide alloy, pottery or man-made polycrystalline diamond to make.
The utility model adopts at the cutting position of steel cutter hub front end blade is installed, and has strengthened the hardness and the cutting power of blade.Add man-hour, at first mill out the screens step that blade is installed, blade is installed in the screens step, then blade is milled to the use size of processing component at the cutting position of its blade front end.Experimental verification is cut work metal with blade, has increased the hardness and the service life of countersink, and converted products can reach more than 4000 still can be continued to use; The stepped hole surface roughness that goes out with this countersink ream is low, can also enhance productivity greatly.The particularly important is, can change the blade on the cutter hub easily according to the processing needs.
The screens step of the front end of the cutter hub of this clip type countersink adopts involute shape structural design, has reduced the cutter cost of manufacture under the prerequisite that has guaranteed blade strength, has saved the making material, and has been convenient to the cleaning of smear metal.Facts have proved that this countersink has very high use value, but wide popularization and application.
Though described embodiment of the present utility model in conjunction with the accompanying drawings, the protection domain that those of ordinary skills do not need various distortion that creativity work just can make or modification still to belong to this patent within the scope of the appended claims.
