Moreover, the handle of a knife rear end is equipped with bearing holder (housing, cover), which installs feeler block, and feeler block rear portion is clamping Portion, two middle side part of clamping part offer limitation clip slot.

Moreover, the handle of a knife rear end is coaxially fixedly mounted with the interior axis that connects with the heart, the fixed suit joint double wedge on the interior axis that connects with the heart, in institute It states and is formed with interior engaging slot in bearing holder (housing, cover), fixation is engaged with the interior engaging slot by combining double wedge between the handle of a knife and bearing holder (housing, cover) Connection.

Moreover, the rear end of the axis that connects with the heart is fixedly mounted with symmetrical positioning pin.

It the advantages of the utility model and has the beneficial effect that：

1, the grinding knife tool structure of the utility model, safe and convenient to use, being provided with wear-resisting salient point makes cutting edge and zero When being ground between part, grinding accuracy of the cutter to part is improved, prevents cutting edge from the phenomenon that excessive wear occur；It is provided with Reinforce the mechanical strength that rib enhances point of a knife and blade.

2, the grinding knife tool structure of the utility model is provided with feeler block convenient for pair between cutter and lathe clamping part Knife；Restricted clip slot is set and does not generate biased when cutter being made to be connect with lathe clamping part.

3, the grinding knife tool structure of the utility model, being provided with fixed keyway makes inside cutter interior engaging component and handle of a knife Between joint it is even closer.

4, design is scientific and reasonable for the utility model, and stable connection is reliable, not easy to wear, and service life is long, convenient for knife Positioning, is a kind of grinding knife tool structure with higher innovation.

Specific implementation mode

Below by specific embodiment, the utility model is described in further detail, following embodiment be it is descriptive, no It is restrictive, protection scope of this utility model cannot be limited by this.

A kind of grinding knife tool structure, including handle of a knife 1 and cutter head 15, knife are formed with rake face 2 on first face, with before this Knife face is formed with main flank 9 on an adjacent face, and minor flank is formed in the cutter head end of rake face and rear apex face common adjacency 7.It is formed with main grinding blade 3 in the outer side edges of rake face, the main grinding blade inner side edge portion is formed with wear-resisting salient point 4.Rake face Front end edge is formed with secondary grinding blade 5, and the end set of pair grinding blade has point of a knife 6.Between main flank and minor flank Stupefied is to reinforce stupefied 8, and main flank is grinding surface 10 close to handle of a knife one end.

Handle of a knife rear end is equipped with bearing holder (housing, cover) 11, which installs feeler block 12, and feeler block rear portion is clamping part 13, Two middle side part of clamping part offers limitation clip slot 14.In order to make the limitation clip slot of cutter be more fixed when being connect with lathe etc., The overall diameter that the interior diameter of limitation clip slot connect convex block with lathe is equal in magnitude.

Handle of a knife rear end is coaxially fixedly mounted with the interior axis 18 that connects with the heart, the fixed suit joint double wedge 17 on the interior axis that connects with the heart, in bearing holder (housing, cover) It is inside formed with interior engaging slot 16, is engaged with interior engaging slot by combining double wedge and is fixedly connected between handle of a knife and bearing holder (housing, cover).Connect with the heart on axis End is fixedly mounted with positioning pin 19.In order to make to be completely embedded between cutter interior conscientiously, the interior diameter of interior engaging slot with combine double wedge 17 overall diameter size is coincide.

Loosening is not generated in order to make positioning pin 19 be more fixed in positioning, and 19 inside middle-end of positioning pin offers pin Nail hole 20.In order to improve the mechanical strength and service life of handle of a knife 1, handle of a knife 1 is a kind of component of high-quality wolfram steel material.

The operation principle and process for using of the utility model：In grinding knife tool before use, passing through the folder on 1 right side of handle of a knife first Holding portion 13 makes to be fixedly connected between the clamp assemblies such as itself and lathe, and make the limitation clip slot 14 of cutter with it is convex on the inside of clamping part Closely agree between rib, cutter is made not generate biased, while the bearing holder (housing, cover) 11 in 13 left side of clamping part and its inside in the running Interior engaging slot 16 and joint double wedge 17 further improve stationarity of the cutter when being connect with lathe, while interior engaging slot 16 And positioning pin 19 inside joint double wedge 17 and pin hole 20 make cutter when lathe is for connection between connection component Positioning is more accurate, the wear-resisting salient point 4 and reinforcement rib 8 of main grinding blade 3 and secondary grinding 5 edge of blade make grinding knife tool with add When being ground between work part, the attrition of cutting edge is made to substantially reduce, while the blade of cutter being made to have more with tip High mechanical strength extends its service life.

The embodiments of the present invention and attached drawing, but it will be appreciated by those skilled in the art that：This practicality is not being departed from In novel and spirit and scope of the appended claims, various substitutions, changes and modifications are all possible, and therefore, this practicality is new The range of type is not limited to embodiment and attached drawing disclosure of that.
