Therefore, it does not meet the existing needs. In this regard, we propose a polishing device for the surface of kitchen appliance hardware. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model is provided with a clamping mechanism. The conventional lower clamping block is inclined toward the outside. When installing the hardware, the hardware is placed between the two clamping blocks. The worm is driven to rotate by turning the hand wheel. The contact surface between the worm and the worm wheel forms a spiral friction transmission surface. The rotation of the worm drives the worm wheel to rotate, and then the adjusting block is driven to rotate by the worm wheel. During the movement, the connecting arm forms traction on the clamping block, so that the clamping block rotates with the rotating shaft at one end of the hardware as the center of the circle, so that the clamping block is constantly close to the hardware to fix the hardware. On the one hand, the clamping mechanism is easy to operate and can quickly clamp and fix the hardware. On the other hand, the self-locking property of the worm and worm wheel can be used to improve the fixing effect of the clamping block on the hardware, providing protection for the grinding work.
[0017] 2. The utility model utilizes a displacement mechanism and a grinding wheel to achieve grinding. By turning on the driving motor, its output shaft drives the grinding wheel to rotate at high speed. At the same time, the servo motor is turned on to drive the threaded rod to rotate. The rotational motion is converted into linear motion under the friction with the sliding block, so that the upper clamping mechanism is driven to displace through the sliding block, and the fixed hardware is gradually brought close to the grinding wheel. When the hardware contacts the grinding wheel, intense friction is generated between the two, resulting in a smooth treatment of the surface of the hardware. At the same time, under the action of the supporting spring inside the fixed seat, the grinding wheel can be closely attached to the surface of the hardware, thereby avoiding loss of contact with the groove structure on the surface of the hardware, and further improving the grinding quality.
[0018] 3. The utility model provides a protective cover above the workbench. When the protective cover is open, the staff can install the hardware. When the protective cover is closed, the negative pressure fan inside the base is turned on to quickly discharge the air inside the protective cover. At the same time, the air outside the dust hood is continuously replenished into the negative pressure fan through the dust suction pipe, forming a higher pressure difference with the outside world. Then, the dust inside the protective cover is sucked into the dust collecting box of the base along with the air, thereby preventing the dust generated by grinding from polluting the workshop.

[0036] Working principle: When in use, turn on the drive motor 13, and its output shaft drives the grinding wheel 12 to rotate at high speed. At the same time, turn on the servo motor 22 to drive the threaded rod 23 to rotate, and the rotational motion is converted into linear motion under the friction with the sliding block 24, so that the upper clamping mechanism 14 is driven to move through the sliding block 24, and then the fixed hardware is gradually approached to the grinding wheel 12. When the hardware and the grinding wheel 12 are in contact, violent friction is generated between the two, forming a smooth treatment on the surface of the hardware.
