Abstract
The utility model relates to a limiting tool for a grinding dead knife, and belongs to the field of knife grinding machining. The limiting tool comprises a tool body and through grooves. The cross section of the tool body is in a right trapezoid shape. The four faces, parallel to the axial direction, of the tool body are respectively an inclined face, a vertical face, a horizontal bottom face and a horizontal top face. The inclined face, the horizontal top face, the vertical face and the horizontal bottom face are connected in sequence, and the included angle between the inclined face and the horizontal bottom face is an acute angle. The through grooves penetrate through the vertical face through the inclined face. The number of the through grooves is two, and the two grooves are located at the same height. The limiting tool further comprises two supporting point columns which are both arranged on the surface of one side, close to the inclined face, of the vertical face. The limiting tool enables knives to be ground more easily and to be smoother, can grind the knives of various angles, and has the advantages of being simple in structure, low in manufacturing cost and convenient to operate.
Description
Technical field
The utility model belongs to the tool grinding manufacture field, specifically, relates to the limiting tool that a kind of grinding bed plate is used.
Background technology
Bed plate is being played the part of important role daily in cutting grass work.The sharpness of bed plate, attitude setting, bed plate angle all affect cuts grass product matter and cuts careless effect.The design of bed plate must meet two conditions, should have enough materials (thickness) to disperse to cut the heat that careless operation produces, and guarantees again to leave space below bed plate, in order to avoid bed plate is dawdled on lawn.
When cutting-height is higher, when the blade of grass of pruning place is more sparse, owing to not having enough blades of grass to carry out Cooling and Lubricator, the temperature at bed plate and hobboing cutter blade place can be higher.If now use thinner bed plate, because its material is not enough to rapid heat dispersing, and make bed plate and hobboing cutter expanded by heating, cause bed plate and hobboing cutter accelerated wear test.Therefore, when cutting-height is higher, should select thicker bed plate.
When cutting-height is low, if use thicker bed plate, can cause the lawn of dawdling, bed plate bottom, not only cause the wearing and tearing on lawn, and the landform risen and fallen can hold up the hobboing cutter group, make cutting-height inconsistent, what the fluctuation shape occurs badly cuts careless outward appearance.In the time of serious, bed plate is upwards held up, thereby directly contacts and destroy the hobboing cutter blade with hobboing cutter.
Even but select right bed plate, bed plate in use also can rust, and the flatness on bed plate inclined plane directly affects the lawn care quality, needs frequent grinding, the grinding on bed plate inclined plane is a technical profession of bottom cutter grinding always, acquires a certain degree of difficulty.
China Patent No.: 201220406923.3, open day: on 03 13rd, 2013, disclose the patent document of a knife board by name, this utility model is a kind of knife board, is applied to the grinding of straight knife tool, be specially adapted to the grinding of woodworking plane cutter blade, it is characterized in that blade is fixed on knife rest, by the fixing grinding angle of pivot pole, and carry out tool grinding in conjunction with sand paper or grinding stone, thereby the acquisition optimum efficiency, this knife board has the characteristics such as simple in structure, easy to operate.But the bed plate that is oblique sword for the edge of a knife, this utility model can not reach the effect of grinding equalizing.
Summary of the invention
The problem that 1, will solve
The problem that is difficult to smooth grinding for the bed plate inclined plane, the limiting tool that the utility model provides a kind of grinding bed plate to use, this frock can make the horizontal grinding in bed plate inclined plane, and can conveniently adjust grinding angle, be the limiting tool that a kind of simple in structure, cheap, easy to operate grinding bed plate is used.
2, technical scheme
For addressing the above problem, the utility model adopts following technical scheme.
The limiting tool that a kind of grinding bed plate is used, described limiting tool comprises frock body, groove; Described frock body cross-section is right-angled trapezium, and four faces that described frock body is parallel on axial direction are respectively inclined-plane, vertical plane, horizontal bottom and horizontal top surface, and described inclined-plane, horizontal top surface, vertical plane and horizontal bottom are connected successively; Angle between described inclined-plane and horizontal bottom is acute angle; Described groove passes the first right angle face from inclined-plane; Described groove has two, is positioned at identical height.
Preferably, described limiting tool also comprises two pivot poles, all is positioned at the surface of close inclined-plane one side on vertical plane.
More preferably, described pivot pole is ripple pearl screw.
Preferably, described groove length is 100～250mm, and width is 20～40mm.
More preferably, described groove length is 200mm, and width is 30mm.
Preferably, the angle between described inclined-plane and horizontal bottom is 75-82 °.
More preferably, the angle between described inclined-plane and horizontal bottom is 80 °.
The utility model in use, adopt pin that the through hole on bed plate closely is connected with the groove of limiting tool, between limiting tool and bed plate, adopt pin to be connected, make the equal horizontal positioned of limiting tool and bed plate inclined plane, and the horizontal plane at place, bed plate inclined-plane is higher than the horizontal plane at limiting tool horizontal top surface place, can also pass through to change the length adjustment limiting tool bevel angle of Zhi Zhudian in addition, thus the cutter of grinding different angles cutting edge.
3, beneficial effect
Than prior art, the beneficial effects of the utility model are:
(1) the utility model cross section is right-angled trapezium, and is parallel to axial direction and is provided with inclined-plane, can make bed plate be arranged on this inclined-plane, thereby make blade maintenance level, can make tool grinding be more prone to, more smooth;
