Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, described ball seal surface grinding, including frame 1, are provided with frame 1 by motor 2
Drive the mill 3 rotated, the top of mill 3 is recessed the spherical slot grinding being adapted with the sealing surface of spheroid 4, a left side for mill 3,
Mounting seat 5 is respectively arranged with the frame 1 of right both sides, the perpendicular of left and right insertion mounting seat 5 is respectively arranged with each mounting seat 5
To bar shaped spacing hole 6, two vertical 6 symmetrical distributions of bar shaped spacing hole, it is equipped with two vertical bar shaped spacing holes 6
One vertically bar shaped spacing hole 6 can move up and down and to hang the connecting rod 7 of spheroid 4, in connecting rod 7 and two mounting seats
It is provided between 5 to by the spacing position-limit mechanism in two vertical bar shaped spacing holes 6 of connecting rod 7, between two mounting seats 5
Connecting rod 7 on be arranged with axle sleeve 8, driving handle 9 is fixed with axle sleeve 8, in axle sleeve 8 and hangs in connecting rod 7 and seals
Placed face down is additionally provided with the connection component for making both mutually be fixedly connected between the spheroid 4 in spherical slot grinding；In this implementation
In example, the structure of position-limit mechanism is：Vertically it is threaded with one respectively at the top of each mounting seat 5 and extends downwardly into corresponding erect
Caging bolt 10 into bar shaped spacing hole 6, every caging bolt 10 can be pressed in the connection in corresponding vertical bar shaped spacing hole 6 down
On bar 7, so as to by connecting rod 7 it is spacing above-mentioned position-limit mechanism structure knot is simple in two vertical bar shaped spacing holes 6, installation tune
Section is convenient；In the present embodiment, every caging bolt 10 is threaded with respectively after extending downwardly into corresponding vertical bar shaped spacing hole 6
One lower limit locking nut 11, preferably caging bolt 10 can so be positioned, avoided because caging bolt 10 loosens
And the occurrence of spacing can not be carried out to connecting rod 7, improve the stability in use of equipment；In the present embodiment, at every
