DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Embodiment 1:

[0019] A rotating mechanism for polishing and grinding. This embodiment is based on the problems in the existing stainless steel product grinding process. In order to achieve fast fixed grinding processing, such as Figure 1-4 As shown, it includes a fixed base 1, a support arm 2 is welded to the top outer wall of the fixed base 1, and a driving unit is arranged on the top of the support arm 2, the driving unit includes a fixed sleeve 4 arranged on the top of the support arm 2, and a rotating shaft 5 is rotatably arranged at the axis center of the fixed sleeve 4, a worm wheel 6 is welded at the axis center of one side of the rotating shaft 5, and a worm 7 is meshed and driven at the bottom of the worm wheel 6, and the worm 7 is connected to a servo motor 8, and a rotating disc 9 is connected to the axis center of the outer wall on the other side of the rotating shaft 5, and a locking unit is arranged on the rotating disc 9;

[0020] By setting up the locking unit, you only need to place the stainless steel product at the axis of the rotating disk 9 and adjust the bidirectional screws in two directions to quickly adjust the locking blocks 17 around the product, thereby greatly speeding up the locking and fixing speed. After fixing, you can also rotate the threaded rod to fine-tune the locking process, further improving work efficiency.

[0021] The four corners of the bottom of the fixed base 1 are bonded with anti-skid rubber pads 3, and the outer wall of the bottom of the anti-skid rubber pad 3 is provided with anti-skid threads. The locking unit includes a first sliding groove 10 opened on the rotating disc 9, and a second sliding groove 11 is opened on the outer wall of the other side of the rotating disc 9. A first bidirectional screw rod 12 is rotatably installed inside the first sliding groove 10, and a second bidirectional screw rod 13 is rotatably installed inside the second sliding groove 11;

[0022] The outer walls of both ends of the first bidirectional screw rod 12 and the second bidirectional screw rod 13 are both screwed with sliding blocks 14, and the size of the sliding blocks 14 is adapted to the size of the first sliding groove 10 and the second sliding groove 11;

[0023] After the product is fixed, it is only necessary to control the rotation speed of the servo motor 8 to drive the stainless steel product to rotate quickly, thereby facilitating the grinding of the product. The meshing of the worm wheel 6 and the worm 7 can avoid loosening during the rotational grinding process, and during stationary grinding, the worm 6 and the worm wheel 7 have a locking function, thereby greatly improving practicality.

[0024] When this embodiment is used, first place the fixed base 1 connected with the anti-slip rubber pad 3 on a horizontal plane, then engage and drive the worm wheel 6 and the worm 7, then combine and install the servo motor 8, then unfold the four locking blocks 17 and move them away from each other, then place the stainless steel product to be polished at the center of the rotating disc 9, then rotate the first bidirectional screw rod 12, thereby driving the sliding blocks 14 to approach each other, and driving the locking blocks 17 to approach each other, thereby squeezing and fixing the stainless steel product, then quickly rotate the second bidirectional screw rod 13 to drive the upper locking blocks 17 to approach each other, and complete further fixation of the stainless steel product. After fixation, observe whether the fixation is tight. If there is still a gap, the locking block 17 can be fine-tuned to fix the stainless steel product in conjunction with the rotation of the threaded rod 16. After fixation, start the servo motor 8, so as to use the worm 7 to drive the worm wheel 6, drive the rotating disc 9 to rotate, thereby driving the stainless steel product to rotate, and then polishing the stainless steel product in conjunction with the manual polishing machine.
