As shown in fig. 7, push-pull mechanism 7, by push-and-pull connector sleeve 27, axis 28 forms.Push-and-pull 27 lower end of connector sleeve is designed as oblique angle
Structure is simultaneously connect with sliding block 8 by axis 28, and the two can relatively rotate around axis 28；It pushes and pulls under 27 upper end of connector sleeve and push top 6
There are certain gaps for the free grafting of the axis at end, push-and-pull 27 hole of connector sleeve and 6 lower end axis radial direction of push top.When sliding block 8 is arcuately led
When rail 9 does movement in a curve, push-and-pull connector sleeve 27 borrows the gap between axis and set and turns round inclination around axis 28 and push and pull connector sleeve
27 with push top 6 lower ends axis occur axial displacement, thus realize sliding block 8 and push top 6 between distance variation.
Such knife sharpener, which has, imitates the artificial round-trip sharpening function of hand push.It is back and forth ground using the round-trip lead screw realization of motor band
Mill.Solve the problems, such as that traditional cutter grinder with grinding wheel abrasion loss is big, this knife sharpener can be used common whetstone in the market and be ground
Mill, the whetstone of replaceable different meshes improve ice by adjusting lower pressure and with the whetstone of different thicknesses to the full extent
Knife service life saves abrasion loss.The machine is positioned at amateur and primary student whets a knife and uses, and is ground, is joined using radian
Examine value are as follows: short-track speeding skating knife R8~12 meter, main road speed skate R20~25 meter.Every kind of speed skate is using three kinds of radian guide rail difference
It is short-track knife R8 meters, R10 meters, R12 meters.Knife R20 meters, R22.5 meters, R25 meters of main road.Guide rail can be replaced according to personal habits come real
The grinding radian of existing skates.Round-trip lead screw is linear slide, and guide rail is camber line sliding, so simple rigid connection cannot be used,
Power transmission is realized in such a way that sliding sleeve cooperates shaft.Because the general effective contact ice face size of skates be 365MM~
465MM or so, the general width of whetstone box available on the market is 50MM~60MM, so round-trip lead screw is selected to be formed as
405mm ensures that the skates of common model can use.The knife board of standard can be interchanged in the pedestal chucking mechanism of the machine design,
Polishing-stone box can install the grinding stone of standard, general size are as follows: 180~200mm of length, 50~60mm of width, thickness 10~
30mm can guarantee that above-mentioned size normal mounting uses, this polishing-stone box uses bolt-type chucking mechanism up and down adjustment, is divided into two
A gear, uses pin hole when installation, convenient and efficient with lower pin hole when work.Currently on the market without finding similar knife sharpener.
