[0002] Screws are tools that use the physical and mathematical principles of the inclined plane, circular rotation, and friction to gradually fasten objects and machine parts. Flat-head screws refer to screws with one flat end. When grinding one end of a flat-head screw, it can be done using a flat-head screw processing end face grinding device.

[0003] The face grinding devices currently available on the market for processing flat-head screws have the following problems in actual use:

[0004] 1. Traditional flathead screw processing end face grinding devices are cumbersome and time-consuming to operate, resulting in low efficiency. They require fixing the flathead screw first, then moving it to contact the grinding device, and then moving it again after grinding. Finally, the screw is released and removed.

[0005] 2. Most face grinding devices for flat-head screw processing produce a lot of waste chips during use because the grinding position of the device is exposed to the outside. These waste chips will fly around, making the device inconvenient to use. Utility Model Content

At this time, the fixing plate 8 will drive the internal threaded sleeve 12 to move until the flat-head screw is in contact with the grinding disc 4. Then, the motor 3 can be used to drive the grinding disc 4 to grind the flat-head screw. After grinding is completed, The screw 7 can be rotated in reverse to place the internal thread sleeve 12 on top of the storage box 17. Then, the external thread pressing rod 13 is rotated to push the flat-head screw into the storage box 17. After that, the external thread pressing rod 13 is rotated back to its original position. It is very convenient to use. At this time, there is no need to fix the flat-head screw, and the storage box 17 can store the flat-head screw. It is very convenient to use and improves work efficiency. In addition, because a side plate 21 is welded to the top of the workbench 1 and a sliding groove 22 is opened on the side of the side plate 21, and a protective cover 26 is fitted onto the surface of the motor 3, and a handle 23 is welded to the surface of the protective cover 26, the surface of the handle 23 is...
