The output ends of the multiple drive motors 5 pass through the support plate 3 and are respectively fixedly connected to multiple U-shaped frames 6.
[0036] In this embodiment, multiple drive motors 5 can drive the U-shaped frame 6 connected to them to rotate.
[0037] As a technical optimization of this utility model, the rear end of the auxiliary plate 26 is fixedly connected to two fixed plates 21, and the lower end of the drive plate 23 is fixedly connected to two limiting rods 22 that are slidably connected to the two fixed plates 21 respectively.
[0038] In this embodiment, the stability of the drive plate 23 movement can be enhanced by the cooperation of two fixed plates 21 and two limiting rods 22.
[0039] As a technical optimization of this utility model, the lower end of the sliding block 9 is in contact with the base 1, and the limiting seat 8 is in contact with the bottom end of the inner wall of the U-shaped frame 6.
[0040] In this embodiment: the lower end of the sliding block 9 is in contact with the base 1 to prevent the sliding block 9 from rotating axially, and the limiting seat 8 is in contact with the bottom end of the inner wall of the U-shaped frame 6 to prevent the limiting seat 8 from rotating axially.
[0041] The working principle and usage process of this utility model are as follows: In use, the mold to be chamfered and ground is placed between two limiting seats 8 inside the U-shaped frame 6. The two threaded rods 7, threadedly connected to the U-shaped frame 6, are rotated, driving the limiting seats 8 to move. The mold is clamped and fixed by the relative movement of the two limiting seats 8. The electric push rod 16 drives the fixing block 18 and rack 15 to move, thereby driving the multiple gears 11 meshing with them to rotate. This, in turn, drives the rotating shaft 10, mounting base 12, worm gear self-locking motor 13, and polishing head 14 connected to them to rotate. The angle of the polishing head 14 can be adjusted to be equal to the chamfer inclination dimension. Then, the cylinder 20 drives the drive plate 23 to move downwards, causing the leftmost polishing head 14 to abut against the chamfer of the rightmost mold. Finally, multiple drive motors 5 drive the U-shaped frame 6 to rotate. The frame 6 rotates, thereby driving the mold to rotate, causing the chamfered edge of the mold to rotate around the polishing head 14, performing rough polishing on the rightmost mold chamfer. Then, the cylinder 20 is activated, driving the drive plate 23 to move upward, causing the polishing head 14 to move upward away from the mold. Then, the servo motor 25 drives the lead screw 24 to rotate, thereby driving the connected sliding block 9 and support plate 3 to move to the right, moving the rightmost mold below the middle polishing head. At this time, the middle mold is located below the coarse polishing head. The cylinder 20 again drives the drive plate 23 to move downward, and multiple drive motors 5 drive the connected U-shaped frame 6 to rotate, thereby driving the mold to rotate, performing medium polishing on the rightmost mold chamfer while performing coarse polishing on the middle mold. The same operation is repeated, causing multiple molds to move to the right in sequence, and being polished by the coarse polishing head, the middle polishing head, and the fine polishing head in sequence, improving the polishing accuracy.
