Description

Technical Field

[0001] The invention relates to the field of mechanical processing equipment, and in particular to a metal plug precision deburring device. Background Art

[0002] Metal plugs are accessories used to close pipes, containers or other openings. They are usually used in situations where fluid leakage or external contaminants need to be prevented from entering. They can be of various shapes and sizes to suit different application scenarios, and are usually made of corrosion-resistant materials such as stainless steel, brass or aluminum to ensure that they can work stably for a long time even in harsh environments.

[0003] Metal plugs will have burrs during the manufacturing process. If these burrs are not handled, they may affect their sealing performance or subsequent assembly process. Therefore, special equipment and technology are needed to remove these burrs in production to ensure the quality and performance of the product. The rotary body style metal plug is the most common plug, which is processed using proprietary deburring equipment.

[0004] The existing rotary body style metal plug deburring equipment has a relatively simple structure, which is mainly composed of a grinding wheel, a belt rotating wheel and a pushing structure. During processing, the grinding wheel and the belt rotating wheel are pressed against the plug, and the pushing structure pushes the plug to move in the gap between the grinding wheel and the belt rotating wheel to remove the burrs. However, this type of equipment can only process a single metal plug per unit time, and the processing efficiency needs to be improved. In addition, although this type of metal plug deburring equipment can complete the burr removal of the metal plug ring surface, it cannot effectively remove the burrs on the end face and needs to be processed by manual polishing or other equipment. The steps are cumbersome and the processing efficiency is low. Summary of the invention

[0035] During specific operation, the main shaft 51 is controlled to rotate by the motor 1 52 , and the main shaft 51 drives the flexible grinding wheel 5 to rotate, and the flexible grinding wheel 5 is used to remove burrs from multiple plugs.

[0036] See also Figure 1 , Figure 2 and Figure 3 The burr removal mechanism 6 includes a plurality of clamping components 621 for clamping the plug, which are equidistantly arranged at one end of the annular shell 4 close to the flexible grinding wheel 5. A coupling rotation component 62 for synchronously rotating a plurality of clamping components on the same annular shell 4 is arranged inside the annular shell 4. A pushing component 61 for controlling the forward and backward position of the plug is commonly arranged inside the annular shells 4 on the left and right sides.

[0037] By using the propulsion assembly and the coupling assembly 62 in coordination, multiple plugs can be fully deburred synchronously by using a single flexible grinding wheel 5 .

[0038] See also Figure 3 , Figure 6 and Figure 7 The material clamping component 621 includes a plurality of round seats 6211. A side wall of the round seat 6211 close to the flexible grinding wheel 5 is provided with a plurality of guide grooves 6214 distributed along its radial direction.
