[0002] Machines are tools that can help people reduce the difficulty of work or save effort. Machines composed of a small number or a single structure are called simple machines, such as chopsticks, brooms and tweezers. Machines composed of multiple parts are called complex machines.

However, the fixedly installed polishing wheel cannot alleviate the rebound vibration and is easily damaged after long-term use. In order to solve the shortcomings of the existing technology, we propose a polishing device for the production of mechanical parts. Utility Model Content

The staff starts the second drive motor 9 and the first drive motor 5. The second drive motor 9 rotates at twice the speed of the first drive motor 5. The output ends of the second drive motor 9 and the first drive motor 5 respectively drive the second polishing wheel 11 and the first polishing wheel 6 to rotate. Then the staff places the shaft to be polished on the first limiting groove 2. Then the staff pushes one end of the shaft to be polished into between the first polishing wheel 6 and the second polishing wheel 11. The second polishing wheel 11, which rotates at a higher speed than the first polishing wheel 6, offsets the friction between the first polishing wheel 6 and the shaft to be polished and drives the shaft to be polished to rotate. The outer sides of the rotating shaft to be polished are polished by the first polishing wheel 6 and the second polishing wheel 11. Then the staff takes the next shaft to be polished and places it on the first limiting groove 2. Pushes the current shaft to be polished on the support plate 3 to move to the second limiting groove 4. The staff repeats the above operations continuously, thereby continuously polishing the shaft to be polished.
[0023] like Figure 3 As shown, the protective assembly 8 includes a second protective cover shell 13, one end of the first drive motor 5 is detachably mounted on one side of the second protective cover shell 13, a bearing 14 is detachably mounted inside the fixed wheel 7, a fixed shaft 15 is detachably mounted on the inner wall of the bearing 14, and one end of the fixed shaft 15 is detachably mounted on one side of the sealing plate 16. When the staff is working, the outer sides of the first polishing wheel 6 and the second polishing wheel 11 are respectively shielded by the first protective cover shell 10 and the second protective cover shell 13, and the staff is not easily harmed by the first polishing wheel 6 and the second polishing wheel 11 when working, thereby improving the protection of the equipment, reducing safety hazards, making the equipment safer to use, and more convenient for the staff to use.
[0024] like Figure 4As shown, the shock absorbing assembly 12 includes a base 17, the bottom of the base 17 is detachably mounted on the top of the polishing device body 1, the outer side of the base 17 is detachably sleeved with a sleeve shell 18, the bottom of the inner wall of the base 17 is detachably mounted with a fixing ring 19, the interior of the fixing ring 19 is detachably mounted with a shock absorbing spring 20, the outer side of the fixing ring 19 is movably sleeved with a movable ring 21, the top of the movable ring 21 is detachably mounted with a mounting plate 22, the top of the mounting plate 22 is detachably mounted with the bottom of the first protective cover shell 10, limiting blocks 23 are detachably mounted on both sides of the inner wall of the base 17, sliding grooves are provided on both sides of the movable ring 21, the outer side of the limiting block 23 is slidably connected with the inside of the sliding groove provided in the movable ring 21, and when the first polishing wheel 6 and the second polishing wheel 11 polish the shaft to be polished, part of the recoil force is respectively generated by the second protective cover shell 13 and When the first protective cover shell 10 is transmitted to the shock absorbing assembly 12, the mounting plate 22 is subjected to the recoil force to drive the movable ring 21 to slide in the base 17 and squeeze the shock absorbing spring 20. When the movable ring 21 is pressed down, it slides with the inside of the base 17 and the outside of the fixed ring 19 to generate friction. The outside of the mounting plate 22 slides with the inside of the sleeve 18 to generate friction. The outside of the limit block 23 and the inside of the slide groove opened by the movable ring 21 generate sliding friction. The multiple friction forces cooperate with the shock absorbing spring 20 to offset part of the transmitted recoil force, thereby achieving the purpose of shock absorption. The first polishing wheel 6 and the second polishing wheel 11 are more stable during polishing and rotation, and the polishing effect is better. The recoil force received by the first polishing wheel 6 and the second polishing wheel 11 during polishing is shared and weakened, and the damage to the first polishing wheel 6 and the second polishing wheel 11 caused by the recoil force is reduced, which can effectively extend the service life.
[0025] How it works
[0026] It should be noted that the utility model is a polishing device for the production of mechanical parts. When in use, the second drive motor 9 and the first drive motor 5 are first started. The second drive motor 9 rotates at twice the speed of the first drive motor 5. The output ends of the second drive motor 9 and the first drive motor 5 respectively drive the second polishing wheel 11 and the first polishing wheel 6 to rotate. Then, the staff places the shaft to be polished on the first limiting groove 2, and then the staff pushes one end of the shaft to be polished into between the first polishing wheel 6 and the second polishing wheel 11. Compared with the first polishing wheel 6, the second polishing wheel 11 that rotates at a higher speed offsets the friction between the first polishing wheel 6 and the shaft to be polished. The friction force drives the shaft to be polished to rotate, and the outer sides of the rotating shaft to be polished are polished by the first polishing wheel 6 and the second polishing wheel 11. Then the staff takes the next shaft to be polished and places it on the first limiting groove 2, and pushes the current shaft to be polished on the support plate 3 to move to the second limiting groove 4. The staff repeats the above operations continuously, thereby continuously polishing the shaft to be polished. When the staff is working, the outer sides of the first polishing wheel 6 and the second polishing wheel 11 are respectively shielded by the first protective cover shell 10 and the second protective cover shell 13. The staff is not easily harmed by the first polishing wheel 6 and the second polishing wheel 11 when working, thereby achieving the purpose of improving the protection of the equipment.
[0027] When the first polishing wheel 6 and the second polishing wheel 11 are rotating at work, one end of the second polishing wheel 11 rotates on the first protective cover shell 10, the first polishing wheel 6 drives the fixed wheel 7 to drive the bearing 14, the bearing 14 rotates on the fixed shaft 15, the fixed shaft 15 is connected to the sealing plate 16 to support the bearing 14, the fixed wheel 7 supports the first polishing wheel 6, and the first protective cover shell 10 supports the second polishing wheel 11. The first polishing wheel 6 and the second polishing wheel 11 are more stable when rotating, so that part of the recoil force received by the first polishing wheel 6 and the second polishing wheel 11 when polishing the shaft to be polished is respectively transmitted by the second protective cover shell 10. The shell 13 and the first protective cover shell 10 are transmitted to the shock absorbing assembly 12. When the recoil force is transmitted to the shock absorbing assembly 12, the mounting plate 22 is driven by the recoil force to drive the movable ring 21 to slide in the base 17 and squeeze the shock absorbing spring 20. When the movable ring 21 is pressed down, it slides with the inside of the base 17 and the outside of the fixed ring 19 to generate friction. The outside of the mounting plate 22 slides with the inside of the sleeve shell 18 to generate friction. The outside of the limit block 23 and the inside of the slide groove opened by the movable ring 21 generate sliding friction. The multiple friction forces cooperate with the shock absorbing spring 20 to offset part of the transmitted recoil force, thereby achieving the purpose of shock absorption.
