Description

Technical Field

[0001] This utility model relates to the field of threaded insert processing technology, and in particular to a device for grinding and optimizing the surface roughness of threaded inserts for new energy vehicles. Background Technology

[0002] New energy vehicle threaded inserts are metal or plastic parts used for assembling related components of new energy vehicles. By being embedded in plastic or other material components of new energy vehicles, they provide reliable threaded connection interfaces for these components. During the assembly process, bolts or screws can be screwed into the threaded inserts to achieve a tight connection between components, ensuring the stability and reliability of the connection.

[0003] During the production of threaded inserts, the surface is relatively rough and needs to be polished and optimized by grinding equipment. However, existing threaded inserts are mostly clamped by chucks or other equipment during polishing. However, the threaded inserts are hollow inside, and clamping them with chucks can easily cause deformation, thus affecting the precision of the threaded inserts.

[0004] Therefore, we propose a surface roughness grinding optimization device for threaded inserts in new energy vehicles to solve the above problems. Utility Model Content

A grinding brush wheel is snapped onto the outer side of the grinding shaft to facilitate the grinding servo motor driving the grinding brush wheel to rotate.

[0011] Specifically, the tensioning mechanism includes a threaded rod, a movable base, four crank assemblies, four clamping assemblies, and a fixed base. The threaded rod is threadedly connected to the inner side of the threaded sleeve. One end of the threaded rod has a cross groove. One end of the threaded sleeve is fixedly mounted with a fixed base. The threaded rod rotatably passes through the fixed base. A movable base is rotatably sleeved on the threaded rod. The movable base has four movable slots on its outer side. Each of the four movable slots has a crank assembly on its inner side. The fixed base has four fixed slots on its outer side. Each of the four fixed slots has a clamping assembly on its inner side.

The output shaft of the moving servo motor 3 is fixedly connected to the ball screw 4, and the ball screw 4 can be rotated by the moving servo motor 3.

[0025] In this embodiment, a grinding base 7 is fixedly installed on the bottom inner wall of the grinding machine tool 1. A grinding groove is provided on one side of the grinding base 7. A grinding servo motor 8 is fixedly installed on the bottom inner wall of the grinding groove. A grinding shaft 9 is fixedly installed on the output shaft of the grinding servo motor 8. A grinding brush wheel 10 is snapped onto the outer side of the grinding shaft 9 to facilitate the grinding servo motor 8 driving the grinding brush wheel 10 to rotate.

[0026] In this embodiment, the tensioning mechanism includes a threaded rod 15, a movable base 16, four crank assemblies, four clamping assemblies, and a fixed base 19. The threaded sleeve 14 is threadedly connected to the threaded rod 15 on its inner side. One end of the threaded rod 15 has a cross groove. One end of the threaded sleeve 14 is fixedly installed with the fixed base 19. The threaded rod 15 rotatably passes through the fixed base 19. The movable base 16 is rotatably sleeved on the threaded rod 15. The movable base 16 has four movable slots on its outer side. The inner side of each of the four movable slots is provided with a crank assembly. The fixed base 19 has four fixed slots on its outer side. The inner side of each of the four fixed slots is provided with a clamping assembly. The four crank assemblies are rotatably connected to the corresponding clamping assemblies.

[0027] In this embodiment, the crank assembly includes a movable column 17 and a crank 18. The movable column 17 is fixedly installed on one inner wall of the movable groove, and the crank 18 is rotatably sleeved on the movable column 17. The crank 18 can be moved by the movable base 16.

[0028] In this embodiment, the clamp assembly includes a fixing post 20, a clamp 21, a clamp post 22, and a tensioning metal block 23. The fixing post 20 is fixedly installed on one inner wall of the fixing groove. The clamp 21 is rotatably sleeved on the fixing post 20. One end of the clamp 21 has a connecting groove. The clamp post 22 is fixedly installed on one inner wall of the connecting groove. One end of the crank 18 is rotatably sleeved on the clamp post 22. The other end of the clamp 21 is fixedly installed with the tensioning metal block 23. The tensioning metal block 23 contacts the inner wall of the threaded insert 13, which facilitates the support and clamping of the inner wall of the threaded insert 13.

[0029] Working principle: When grinding the surface of the threaded insert 13, first open the protective door 2, place the threaded insert 13 onto the rotating shaft 12, and then rotate the threaded rod 15 with a Phillips screwdriver. The threaded rod 15 is threadedly connected to the threaded sleeve 14, which is fixedly installed on the rotating shaft 12. Therefore, the threaded rod 15 rotates away from the threaded sleeve 14. The movable base 16 is rotatably connected to the threaded rod 15. The movement of the threaded rod 15 drives the movable base 16 to move horizontally. The movement of the movable base 16 drives the four movable columns 17 to move, which in turn drives the four cranks 18 to move. Each of the four cranks 18 has a clamp 21 rotatably installed on one side. Each of the four clamps 21 is rotatably sleeved on the corresponding fixed column 20. Therefore, the movement of the four cranks 18 drives the four clamps 21 to rotate around the corresponding fixed column 20. The rotation of the four clamps 21 causes the corresponding tension metal block 2 to rotate. The ball screw 4 contacts the inner wall of the threaded insert 13, thus providing internal support for the threaded insert 13. Then, the moving servo motor 3 is started, which drives the ball screw 4 to rotate, thereby driving the slider 5 to move. At the same time, the grinding servo motor 8 and the rotating servo motor 11 are started, and the grinding servo motor 8 and the rotating servo motor 11 rotate in opposite directions. The grinding servo motor 8 drives the grinding shaft 9 to rotate, which in turn drives the grinding brush wheel 10 to rotate. The rotating servo motor 11 drives the rotating shaft 12 to rotate, which drives the tensioning mechanism to rotate. The tensioning mechanism drives the threaded insert 13 to rotate, so that it contacts the grinding brush wheel 10, thereby achieving surface grinding. At the same time, the distance between the grinding brush wheel 10 and the threaded insert 13 can be adjusted by replacing it with different models and sizes of grinding brush wheels 10, so as to adapt to different models and sizes of threaded inserts 13.

[0030] The technological advancements of this invention compared to existing technologies are as follows: the inner wall of the threaded insert 13 can be supported and clamped, preventing deformation of the threaded insert 13 caused by clamping. At the same time, through the set moving mechanism, the threaded insert 13 can reciprocate to contact the surface of the grinding brush wheel 10, thereby improving the surface polishing effect and increasing the practicality of the equipment.
