[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to secure a fastener. It is an essential component in all manufacturing machinery. Depending on the material, nuts are classified into several types, such as carbon steel, stainless steel, and non-ferrous metals.

[0003] A clamping device for precision nut machining, disclosed in announcement number CN218696320U, relates to the field of precision nuts. It includes a support base plate with uniformly distributed fixing through holes on its top surface. A top arc-shaped block is horizontally welded to the top surface of the support base plate. A snap-fit ​​arc groove is formed on the arc-shaped side of the top arc-shaped block, and a side arc-shaped groove is formed on one side of the top arc-shaped block. Graduation lines are uniformly distributed on one side of the top arc-shaped block. A fastening screw is horizontally inserted into the inner side of the side arc-shaped groove. A movable base block is connected to the arc-shaped side of the top arc-shaped block. A pointing needle is welded to one side of the movable base block, and an adjusting screw is horizontally inserted into one side of the movable base block. A pressing top plate is symmetrically arranged on the top surface of the movable base block. The screw-adjustable clamping structure makes clamping more stable. Simultaneously, the multi-angle adjustment structure allows adjustment to a specified angle to meet machining operations, and precise indication makes machining more accurate.

[0004] After the above-mentioned device processes the nut, iron filings are easily left in the arc-shaped groove and clamping plate. However, it is difficult to clean the filings effectively by hand.

In addition, the filings left in the arc-shaped groove can easily cause blockage when adjusting the arc-shaped block, thus affecting the processing and use of this device. Therefore, it is necessary to provide a new precision nut processing positioning device to solve the above-mentioned technical problems. Utility Model Content

[0030] Working Principle: When using this device, the base plate 1 is fixed to the nut processing table through the positioning hole 2. The nut to be processed is placed in the clamping plate 504. The throttle 502 is rotated, causing the bidirectional screw 501 to rotate, bringing the clamping plates 504 on the mounting block 503 closer together to clamp and position the nut. After moving the moving base block 4 and connecting block 6 on the arc block 3 to the appropriate processing angle, the turntable 8 and fixing screw 7 are tightened to lock the adjusted moving base block 4, ensuring the device can be used for processing. When cleaning debris after processing, the fixing cover 12 is engaged on the moving base block 4. After turning on the air pump 1304, the fixing plate 1403 is manually gripped. Through the universal ball 1301, adjusting plate 1402, adjusting rod 1404, and spring 1405, the shavings suction cup 1305 on the connecting pipe 1302 can... The clamping plate 504 can be moved within the device, allowing the chip suction cup 1305 to be adjusted at multiple angles. This effectively attracts the edges and corners of the clamping plate 504, ensuring the cleaning effectiveness of the device. After cleaning the clamping plate 504, the sealed rotating door on the collection box 1303 is opened, and the internal debris is cleaned. The fixing screw 7 is then loosened, and the connecting block 6 drives the magnetic suction rod 903 on the connecting rod 901 and the collar 902 to move within the arc groove 10 and arc slide groove 11 of the arc block 3. This attracts the debris generated during nut processing, preventing the debris from clogging the arc groove 10 and arc slide groove 11 and affecting the adjustment and use of the arc block 3. The discharge groove 904 facilitates the removal of the magnetic suction rod 903 after the chips are attracted, allowing for cleaning of the attracted chips for subsequent use.
