Description

Technical Field

[0001] This utility model relates to the technical field of hardware processing, specifically to a rounded corner grinding device for hardware processing. Background Technology

[0002] Hardware refers to tools made of metals such as gold, silver, copper, iron, and tin through processing and casting, used for fixing things, processing things, decoration, etc.

[0003] In hardware processing, rounding grinding is required. A hardware rounding grinding device, such as the one described in Chinese Patent Publication No. CN213054051U, fixes the hardware to the upper surface of a turntable. Rotating the lower rocker arm causes the upper rocker arm to push a clamping plate through the first movable section to hold the cylindrical hardware. Rotating the bolts on the sides of the lower rocker arm, upper rocker arm, and first movable section respectively tightens the clamps, thus securely fixing the hardware to the upper surface of the turntable. Furthermore, rotating the bolts on the sides of the upper fixed section and the second movable section... Bolts can be tightened individually, making it easy to secure the grinder to one end of the second movable section. At this time, starting the motor can drive the main rotating ring and the main gear to rotate. The main rotating ring then drives the auxiliary rotating ring to rotate through the connecting rod. This prevents the main gear from disengaging from the auxiliary gear, allowing the main gear to drive the auxiliary gear to rotate around it in a circle. The auxiliary gear can then drive the telescopic rod to rotate through the upper fixed section. The telescopic rod then drives the grinder to rotate through the second movable section. By adjusting the telescopic rod, the grinder can be adjusted to multiple angles, improving both flexibility and grinding efficiency and precision.

[0004] However, this device is difficult to polish round parts evenly, making it impractical. Utility Model Content

Then, turn the three sets of handles 12 respectively to make the corresponding clamping screws 11 rotate. The clamping screws 11 are screwed into the clamping screw sleeve 10. Under the rotational connection of the bearing 13, the clamping plate 14 slides in the constraint groove 9 until it acts on the outer side of the part to clamp it, so that it is fixed in the center position of the rotating table 7 inside the placement groove 8. Then, the drive motor 5 is rotated and the linkage shaft 6 drives the rotating table 7 to rotate stably at the top of the support frame 4, thereby driving the polishing part to rotate. At the same time, the polishing machine 1 is used to perform uniform rounded corner polishing on the circumference through the rotating polishing disc 2.
