For achieving the above object, the utility model provides following technical scheme: a kind of ball valve grinder, include frame, it is characterized in that: in described frame, be provided with for the fixing spin finishing platform of spheroid, drive drive unit that spin finishing platform rotates and for grinding the grinding tool of spheroid, described spin finishing platform includes rotating disc and lower grinding packing ring, lower grinding packing ring and rotating disc coaxially arrange, lower grinding packing ring upper port is provided with taper grinds, described rotating disc drives to be connected with drive unit realizes rotating disc rotation, described drive unit is connected with for controlling the rotation speed control mechanism of rotating, described grinding tool includes the frock body of cup-shaped, frock body oral area is provided with taper grinds.
By adopting technique scheme, spheroid is placed on lower grinding packing ring, by rotating disc, realize the rotation of spheroid, the hand-holdable grinding tool of operating personnel grinds spheroid, realizes the semi-automatic grinding to spheroid, while needing valve seat and spheroid match grinding, change grinding tool into valve seat, simple to operation, this grinder has simple in structure, the advantage that cost is low.
The utility model is further set to: the frock body oral area of described grinding tool has extended axially boss, and boss thickness is less than frock base side wall thickness, and one end end face that described frock body closes on boss is inclined-plane, and boss end forms taper grinds.
By adopting technique scheme, the taper grinds on grinding tool forms on boss, and the thickness of boss is less than frock body wall thickness, makes that the contact area of taper grinds and spheroid is little and grinding tool quality is large, raising grinding efficiency.
The utility model is further set to: the frock body bottom of described grinding tool is provided with and adds material through hole.
By adopting technique scheme, convenient reinforced.
The utility model is further set to: described drive unit is motor, described rotating disc central shaft position is provided with installing hole, the interior realization of installing hole that the output shaft of motor is fixedly assemblied in rotating disc drives connection, and described rotation speed control mechanism is frequency converter, and described frequency converter is connected with Electric Machine Control.
By adopting technique scheme, adopt motor to drive, driving device structure is simple, easy for installation, and on motor, connect frequency converter, realize the control to motor output speed, thereby the rotating speed of controlling rotating disc, the control of grinding rotating speed, has advantages of simple to operation.
The utility model is further set to: described lower grinding packing ring is detachably arranged on rotating disc.
By adopting technique scheme, be convenient for changing the attrition process that lower grinding packing ring adapts to different-diameter spheroid.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the ball valve grinding machine structure schematic diagram of the utility model specific embodiment;
Fig. 2 is the grinding tool structural representation of this practicality brain wash specific embodiment.
The specific embodiment
Referring to accompanying drawing 1 and accompanying drawing 2, the disclosed a kind of ball valve grinder of the utility model, includes frame 1, is provided with for the spin finishing platform 2 of fixing spheroid, drive drive unit 3 that spin finishing platform 2 rotates and for grinding the grinding tool 4 of spheroid in frame 1.Described spin finishing platform 2 includes rotating disc 21 and lower grinding packing ring 22, and lower grinding packing ring 22 is detachably arranged on rotating disc 21 (can adopt and be threaded, or clamping, or screw connection etc.), and lower grinding packing ring 22 coaxially arranges with rotating disc 21; Lower grinding packing ring 22 upper port are provided with taper grinds; The mounting groove 211 that grinds packing ring 22 assemblings under confession is set in rotating disc 21 upper surfaces, and on rotating disc 21, is provided with two coaxial mounting grooves 211, facilitate the assembling of the lower grinding packing ring 22 of two kinds of diameters, with the spheroid adapting within the scope of different-diameter, place and grind.Described rotating disc 21 drives to be connected with drive unit 3 realizes rotating disc 21 rotations, and described drive unit 3 is connected with for controlling the rotation speed control mechanism (not shown) of rotating disc 21 rotating speeds; In this specific embodiment, drive unit 3 is motor, and rotation speed control mechanism is frequency converter (not shown), and frequency converter is connected with Electric Machine Control, realizes the adjustable of motor output speed, and the output shaft of motor is installed rotating disc 21; Certainly revolution speed control device can also be gear shift, as gearbox, has the defect of mechanism's complexity.In frame 1, be provided with the mounting base 11 for fixed electrical machinery, on mounting base 11, be fixed with bearing block 5, bearing block 5 includes fixed head 51, on fixed head 51, be formed with Connection Block 52, Connection Block 52 is provided with axial sleeve joint hole 53, sleeve joint hole 53 is up big and down small stepped hole, is equipped with thrust ball bearing 6 on the step surface of sleeve joint hole 53; Described spinning Pan21 bottom centre shaft position is axially extended with the adapter sleeve 212 in the adaptive aperture that inserts sleeve joint hole 53 downwards, and the output shaft of described motor is assemblied in installing hole, to realize driving on adapter sleeve 212 and connects; The bottom supporting of described spinning dish 21 is on thrust ball bearing 6.
