[0002] A bolt is a mechanical part, a cylindrical threaded fastener used with a nut. It consists of a head and a shank (a cylinder with external threads), and is used to fasten two parts with through holes.

[0003] Bolts have threads on their surface. During the production and processing of these threads, a large number of burrs and flash are inevitably generated on the thread surface. To improve the quality of bolts, after the threads are processed, the bolts often need to be ground to remove burrs, flash, and other defects. However, there are no dedicated devices for bolt grinding and polishing. Common grinding equipment is generally used to grind bolts. This grinding method is not only inefficient, but it is also easy to over-grind the bolt threads and cause damage, which cannot meet the user's needs. Utility Model Content

[0014] The following detailed explanation illustrates the specific implementation methods: like Figures 1 to 2 As shown: A bolt grinding device includes a flipping assembly and a grinding vibrating screen assembly. The grinding vibrating screen assembly is installed at the flipping assembly, and the flipping assembly is used to flip the grinding vibrating screen assembly so that the grinding vibrating screen assembly can be flipped as needed. The grinding and vibrating screen assembly includes a grinding barrel 4, a vibrating module, and two sets of grinding modules. Both ends of the grinding barrel 4 are provided with end caps 5 to facilitate the opening and closing of both ends of the grinding barrel 4. The vibrating module is fixedly installed in the middle of the grinding barrel 4. A set of grinding modules is provided at each end of the vibrating module, so that the vibrating module can drive the two grinding modules to vibrate. The grinding modules are located between the vibrating module and the inner top wall of the grinding barrel 4, so that the user can insert bolts into the two grinding modules through the opening at the end cap 5 of the grinding barrel 4. The vibration module includes a support frame 6 and two vibrators 8. The support frame 6 is fixedly installed in the middle of the grinding barrel 4. The support frame 6 is installed in the middle of the grinding barrel 4 through a first buffer sleeve 7. The first buffer sleeve 7 is fixedly installed on the inner side wall of the grinding barrel. The first buffer sleeve 7 can reduce the vibration of the vibrator 8 transmitted to the grinding barrel 4, so that the vibrator 8 can better vibrate the grinding module. The vibrator 8 is installed in the middle of the support frame 6, and the grinding module is installed at the vibrator 8. The grinding module includes a grinding screen 9 and several guide rods 10. The bottom of the grinding screen 9 is fixedly connected to a vibrator 8, which can drive the grinding screen 9 to vibrate. The open end of the grinding screen 9 is connected to the inner top wall of the grinding barrel 4 through a second buffer sleeve 11, so that the second buffer sleeve 11 can seal the gap between the grinding screen 9 and the top wall of the grinding barrel to prevent bolts from accidentally entering. The second buffer sleeve 11 is fixedly installed on the inner top wall of the grinding barrel 4. Several guide rods 10 are evenly arranged on the side wall of the grinding barrel 4. The guide rods 10 can transmit the vibration to the abrasive in the middle of the grinding screen 9, so that the abrasive can better grind the bolts.

[0015] The grinding screen 9 has a bucket-shaped structure. The end of the grinding screen 9 with the smaller diameter is fixedly connected to the vibrator 8, which makes it easy to concentrate the ground bolts in the middle of the grinding screen 9, and at the same time makes it easy for the abrasive to pass through the grinding screen 9.

[0016] The flipping assembly includes a first buffer sleeve 7 and a second buffer sleeve 11, both made of rubber material, which can reduce the vibration transmitted to the grinding barrel 4.

[0017] The tilting assembly includes a frame 1, a drive motor 2, and a rotating shaft 3. The grinding barrel 4 is rotatably mounted on the frame 1 via the rotating shaft 3. The output shaft of the drive motor 2 is connected to the rotating shaft 3 via a coupling. The drive motor 2 is fixedly mounted on the frame 1, and the drive motor 2 can drive the grinding vibrating screen assembly to tilt via the rotating shaft 3.

[0018] The specific implementation process is as follows: When using this bolt grinding device, first open both end caps 5 in sequence, and place the bolts to be ground into the two grinding sieve barrels 9 respectively. Then, put a sufficient amount of abrasive into the grinding barrel 4, with the abrasive occupying about half of the space in the grinding barrel 4. Close the end caps 5, and then start the vibrator 8. The vibrator 8 drives the grinding sieve barrel 9 to vibrate at the support frame 6. The grinding sieve barrel 9 drives the guide rod 10 to vibrate together. The grinding sieve barrel 9 and the guide rod 10 can drive the abrasive in the grinding barrel 4 to grind the bolts in the grinding sieve barrel 9 in the lower space. After the bolts in the grinding sieve barrel 9 are ground, start the drive motor 2. The drive motor 2 drives the grinding barrel 4 to rotate 180 degrees through the rotating shaft 3. The abrasive also passes through the grinding sieve barrel 9 and enters the other grinding sieve barrel 9. The ground bolts are left in the grinding sieve barrel 9 at the top of the grinding barrel 4. The user can then open the end cap 5 at the top of the grinding barrel 4, take out the ground bolts, and put the bolts to be ground back into the grinding sieve barrel 9 at the top. Repeat the above process to continuously grind the bolts.

[0019] This bolt grinding device involves placing bolts into two grinding sieves 9 and adding sufficient abrasive to the grinding barrel 4. The end cap 5 is then closed, and the tilting assembly is activated to position the grinding barrel 4 vertically, allowing the abrasive to enter the lower part of the grinding barrel 4. The vibrator 8 is then activated to grind the bolts in the grinding sieves 9 at the bottom of the grinding barrel 4. After grinding, the tilting assembly is activated again, causing the grinding barrel 4 to rotate 180 degrees to grind the bolts at the other end. The ground bolts can then be removed. This process can be repeated to grind bolts in batches, effectively improving grinding efficiency and reducing the possibility of bolt damage during grinding.
