Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present utility model.
Description of the embodiments
Embodiments of the present utility model are further described below with reference to the accompanying drawings.
As shown in fig. 1, a ball valve ball fine grinding fixing tool comprises a frame 1, a rotary grinding table 2 is arranged on the frame, the rotary grinding table 2 is disc-shaped, a driving motor 3 is arranged below the rotary grinding table 2, an output shaft of the driving motor 3 is in plug-in connection with the rotary grinding table 2, the driving motor 3 is a gear motor, the rotation speed of the rotary grinding table 2 is proper, the grinding effect is ensured, a slot 4 for fixing a ball body is arranged in the middle of the rotary grinding table 2, a limit rod 5 is arranged above the slot 4, the limit rod 5 is telescopic, two ends of the rotary grinding table 2 corresponding to the limit rod 5 are radially distributed along the grinding table, 3 groups of mounting holes 6 are symmetrically arranged relative to the center of the disc, the mounting holes are additionally arranged according to the use condition, two ends of the limit rod 5 are fixed in the mounting holes 6 through adjusting bolts 7, mounting rings 8 are arranged at two ends of the limit rod 5, internal threads matched with the adjusting bolts 7 are arranged in the mounting rings 8 and the mounting holes 5, and the distance between the limit rod 5 and the rotary grinding table 2 can be controlled through the rotating adjusting bolts 7.
When the device is used for fixing the ball, firstly, the length of the limiting rod 5 is adjusted according to the diameter of the ball, the limiting rod 5 is not too long, the middle part is possibly bent downwards due to the pressure of the ball to be used, after the length is confirmed, the limiting rod passes through a middle channel of the ball, the limiting rod is fixed in a mounting hole 6 through an adjusting bolt 7, the adjusting bolt 7 is adjusted, the distance between the limiting rod 5 and the rotary grinding table 2 is adjusted, the surface of the ball is in contact with a slotted hole 4, the slotted hole 4 supports the ball, and the fixing is completed.
Further, the rotary grinding table 2 is provided with 2 sliding grooves 9, the sliding grooves 9 are symmetrically arranged relative to the center of the rotary grinding table 2, positioning blocks 10 are slidably arranged in the sliding grooves 9, and after the ball is fixed by the limiting rod 5 and the slotted hole 4, the positioning blocks 10 are slidably abutted against the surface of the ball, so that the fixing effect is further enhanced.
In this embodiment, the frame 1 is further provided with a plurality of baffles 11, and the baffles 11 are disposed around the rotary grinding table 2 and are used for blocking flying scraps generated during grinding the ball.
The examples should not be construed as limiting the utility model, and any non-inventive modifications based on the spirit of the utility model should be regarded as being within the scope of the utility model.
