Abstract
The utility model relates to a grinding device for a sealing face of a valve base and a ball of a ball valve, in particular to a grinding tool for a ball valve grinding machine. The grinding tool for the ball valve grinding machine is used for grinding a ball of a ball valve. According to the scheme, the grinding tool for the ball valve grinding machine comprises a cup-shaped tool body and a conical grinding opening formed in the opening portion of the tool body, the opening portion of the tool body extends axially to form an annular boss, the thickness of the annular boss is smaller than that of the side wall of the tool body, the end face of one end, close to the annular boss, of the tool body is a slope, and the conical grinding opening is formed in the end portion of the annular boss. Compared with the prior art, the grinding tool for the ball valve grinding machine has the advantage of being high in grinding efficiency.
Description
Technical field
The utility model relates to valve seat and the ball seal face milling apparatus of ball valve, and the definite grinding tool that says a kind of ball valve grinder, for mill ball valve sphere.
Background technology
The grinding tool using on conventional ball valve grinder, generally includes the frock body of cup-shaped, and the oral area of frock body is formed with taper grinds; Frock body is straight barrel type, and its taper grinds directly forms at frock body oral area; The grinds area forming is large, causes grinding efficiency low; During particularly for hand lapping, the power that hand acts on grinding tool is little, mainly relies on grinding tool gravity to form the grinding pressure of taper grinds to spheroid, and the area of grinds is large, affects grinding efficiency.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide the grinding tool of the ball valve grinder that a kind of grinds area is little, has advantages of that grinding efficiency is high.
For achieving the above object, the utility model provides following technical scheme: a kind of grinding tool of ball valve grinder, include the frock body of cup-shaped and the taper grinds on frock body oral area, it is characterized in that: described frock body oral area has extended axially annular boss, annular boss thickness is less than frock base side wall thickness, one end end face that described frock body closes on annular boss is inclined-plane, and annular boss end forms described taper grinds.
By adopting technique scheme, form the less boss of wall thickness, in boss end, form taper grinds, do not affect grinding tool wall thickness,, in the weight situation of grinding tool, reducing the area of taper grinds, improve the pressure of taper grinds to spheroid, improve grinding efficiency.
The utility model is further set to: the height of described annular boss is 1cm ~ 2cm, and thickness is 0.5cm ~ 0.8cm.
By adopting technique scheme, annular boss and taper grinds easy to process.
The utility model is further set to: described frock body ramp angle of inclination is 120 °≤α≤160 °.
By adopting technique scheme, realize the sidewall of frock body and can not interfere spheroid, meanwhile, guarantee frock base side wall thickness.
The utility model is further set to: the bottom of described frock body is provided with charging aperture, and charging aperture is positioned at frock body bottom center position.
By adopting technique scheme, convenient reinforced.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model specific embodiment structural representation.
The specific embodiment
Referring to accompanying drawing 1, the grinding tool of the disclosed a kind of ball valve grinder of the utility model, includes the frock body 1 of cup-shaped and the taper grinds 2 on frock body 1 oral area.Described frock body 1 oral area has extended axially annular boss 3, and annular boss 3 thickness are less than frock body 1 wall thickness, and the height of annular boss 3 is 1cm ~ 2cm, and thickness is 0.5cm ~ 0.8cm.One end end face that described frock body 1 closes on annular boss 3 is that 11 angles of inclination, 11， inclined-plane, inclined-plane are 120 °≤α≤160 °.Annular boss 3 ends form described taper grinds 2; Taper grinds 2 is processed to form in the inner side of annular boss 3.Form the less boss of wall thickness, in boss end, form taper grinds, do not affecting grinding tool wall thickness,, in the weight situation of grinding tool, reduce the area of taper grinds, improve the pressure of taper grinds to spheroid, improve grinding efficiency.
The bottom of described frock body 1 is provided with charging aperture 12, and charging aperture 12 is positioned at frock body 1 bottom center position.Facilitate like this in process of lapping reinforced.
Claims (4)
