Description
Technical field
The utility model patent relates to a kind of whetstone device, particularly a kind of whetstone device moving back and forth the auto-compensation whetstone height of sharpening for cutter.
Background technology
The principal item of Kitchen knife is kitchen knife, and existing Kitchen knife normally utilizes whetstone, the hand grinding mode directly moved back and forth on whetstone by the hand-held cutter of sharpening personnel.Mainly there is the problem of two aspects in this mode, one is that tool lapping quality is uneven, and the waste of the service life namely after grinding after the sharpness of cutter, grinding once and every grinding cutter all affects by the height of sharpening personnel level of skill.Two is that whetstone consumption is large, and waste is serious.Its main cause is that the distance that cutter moves back and forth is less than whetstone length, otherwise can not form continuous grinding or hit cutter, whetstone is after the use of long period, and its upper surface forms spill low between the senior middle school of two ends, causes whetstone to waste serious.Therefore, need to arrange a whetstone device, by the compensation mechanism in whetstone arranged outside whetstone thickness wear extent, realized the compensation of whetstone thickness wear extent by this compensation mechanism.Chinese patent notification number CN203751840U, date of declaration on August 6th, 2014, invention and created name " the whetstone device of highly automated compensation ".This patent document discloses a kind of whetstone device moving back and forth knife sharpener for cutter, the whetstone utilizing this device to install automatically can complete the compensation of setting thickness after thickness wears away setting value, but the mount pad bracing or strutting arrangement in this device can only provide multistage support, the stepless support of arbitrary height in the scope that can not afford redress, and this apparatus structure is complicated, manufacturing cost is high.For this reason, require further improvement.
Summary of the invention
The utility model object is for the deficiencies in the prior art, there is provided a kind of whetstone device of auto-compensation height, this device, in the reciprocating movement of cutter, can compensate the wear extent of whetstone thickness in time, and structure is simple, easy to process, low cost of manufacture.
For achieving the above object, the utility model adopts following technical scheme.
A whetstone device for auto-compensation height, comprises support and establishes whetstone mount pad, height compensation and mount pad bracing or strutting arrangement thereon, and support is provided with the guider for whetstone mount pad vertical lifting guiding; Described mount pad bracing or strutting arrangement comprises the first cam wedge of the side formation cam curved surface that whetstone mount pad end is provided with; Described support is positioned at outside corresponding end that whetstone mount pad is provided with the first cam wedge and is provided with rotating first fan-shaped support plate, the free end of the first fan-shaped support plate forms camshaft support face, is provided with the first flexible member between the first fan-shaped support plate and support; When whetstone mount pad is positioned at the arbitrary height of lifting range, first fan-shaped support plate is abutted against by the cam curved surface of its camshaft support face and the first cam wedge by the resilient force of the first flexible member, forms the supporting construction stoping whetstone mount pad to decline.
Adopt the utility model of preceding solution, during use, whetstone holder is installed fixing bar shaped whetstone, form the anti-supporting descending to whetstone mount pad by the cam wedge on whetstone mount pad and the first fan-shaped support plate be connected on cam wedge thereof, reach make bar shaped whetstone, the chain of command of height compensation is positioned at same plane.In sharpening process, whetstone is lost to plane gradually gradually lower than the chain of command of height compensation, after the lifting that height compensation is formed whetstone mount pad, first fan-shaped support plate of cam wedge side is under the resilient force of the first flexible member, free end keeps abutting towards cam wedge deflection with the cam curved surface of cam wedge, thus guarantor forms anti-supporting descending to whetstone mount pad all the time.Due to the supporting role of this cam structure, when no matter whetstone mount pad bears great sharpening pressure, it all has reliable support; And no matter hoisting depth size, timely secure support can be provided.Its structure is simple, easy to process, and manufacturing cost and use cost is low.
Wherein, the first flexible member comprises and the one in the torsion spring forming different annexation between the first fan-shaped support plate and support, extension spring and Compress Spring.
