Description

Technical Field

[0001] This utility model relates to the field of laser coating removal technology, specifically a local polishing mechanism. Background Technology

[0002] Laser coating removal is a precision surface treatment technology that uses a high-energy laser beam to selectively remove the coating from the surface of the target material without damaging or minimizing the impact on the substrate material. In existing technologies, local polishing of tiny rods requires consideration of the overall removal effect and precise selective removal of the coating. However, since the diameter of tiny rods is approximately 1.0 mm, it is very difficult to precisely remove the coating locally. Traditional coating removal methods are difficult to completely remove the coating from all parts of the rod.

[0003] For example, the authorized patent document with application number CN202121780170.8 discloses a polishing mechanism for a polishing machine, including a device body, a support assembly, and a snap-fit ​​assembly. The device body includes a polishing machine, with a fixed plate fixedly connected to one side of the polishing machine, and a support assembly provided on one side of the fixed plate. The position of the grinding disc is adjusted by setting the support assembly. By starting the motor, the motor drives the first threaded rod to rotate, and the first threaded rod rotates within the support seat. The support seat makes the rotation of the first threaded rod more stable. The first threaded rod drives the driving wheel to rotate, and the driving wheel meshes with the driven wheel to drive the sleeve to rotate. The rotation of the sleeve drives the second threaded rod to rotate, and the rotation of the second threaded rod can drive the first movable plate to rise and fall. The rising and falling of the first movable plate drives the first slider to move. The first slider is provided on one side of the first movable plate, and the first slider is movably connected to the first slide groove. At the same time, the first slider is sleeved on the surface of the slide rod.

[0004] The aforementioned patents cannot completely remove the bar material from all directions, and it is difficult to perform local polishing on small bars. Therefore, we need to provide a local polishing mechanism. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides a technical solution: a local polishing mechanism, including a base 1, a top plate 2, a tray 3 and a laser plating removal mechanism 4; the top plate 2 is fixedly installed on the top of the base 1 by four columns, the tray 3 for placing the rod body is installed on the top of the base 1, and the laser plating removal mechanism 4 for removing the plating layer from the surface of the rod body is provided at the bottom of the top plate 2.

[0029] The laser plating removal mechanism 4 includes a mounting frame 41 fixedly installed at the bottom of the top plate 2. A threaded rod 42 is rotatably installed inside the mounting frame 41. A drive seat 43 is threadedly installed on the surface of the threaded rod 42. A laser surface polisher 44 is fixedly installed on one side of the drive seat 43. A first motor 45 is installed on the top of the threaded rod 42.

[0030] Guide bars 5 are fixedly installed on both sides of the drive base 43, and guide grooves 6 for sliding of the guide bars 5 are opened on both sides of the inner wall of the mounting bracket 41.

[0031] In this embodiment, as Figure 1 As shown, the bar body to be polished is inserted into the insert 9. Multiple bars can be inserted into the tray 3. The second motor 121 is started to drive the tray 3 to rotate, rotating the bar body to the side of the starter 16. The rotation of the tray 3 will drive several sliding seats 122 at its bottom to rotate in the annular groove 13, providing support for the rotation of the tray 3. The cylinder 17 is started to drive the push block 15 to move, so that the top contact wheel of the starter 16 is in contact with the surface of the bar body. The rotation of the top contact wheel of the starter 16 drives the bar body to rotate, and the insert 9 at the bottom of the bar body will rotate in the mounting base 8. The first motor 45 is started to drive the threaded rod 42 to rotate, controlling the drive seat 43 to slide vertically on the mounting frame 41. A laser surface polisher 44 is installed on one side of the drive seat 43. The laser surface polisher 44 polishes the surface of the bar body. As the bar body rotates and the height of the laser surface polisher 44 is adjusted, the set length area of ​​the bar body is polished.

[0032] Both sides of the surface of the two guide bars 5 are embedded with balls 7, and the surface of the balls 7 is in contact with the inner wall of the guide groove 6;

[0033] Specifically, such as Figure 3 As shown, the guide bar 5 is located in the guide groove 6. The movement of the drive seat 43 will cause the guide bar 5 to slide in the guide groove 6. At the same time, the ball bearings 7 on the surface of the guide bar 5 are in contact with the inner wall of the guide groove 6, which reduces the friction when the drive moves.

[0034] The surface of the tray 3 is integrally machined with several mounting seats 8 for placing the rod body. A tube 9 is rotatably installed in the round hole at the top of the mounting seat 8. A protruding post 10 is fixedly installed at the bottom of the tube 9. The bottom of the protruding post 10 penetrates the bottom of the mounting seat 8 and is equipped with an anti-detachment part.

[0035] Furthermore, such as Figure 6 As shown, the bottom insert 9 of the bar body will rotate within the mounting base 8. Since the rotatable insert 9 is provided on the top of the mounting base 8, the rotation of the bar body is prevented from rubbing within the mounting base 8. Furthermore, the protruding post 10 at the bottom of the insert 9 penetrates through the bottom of the mounting base 8, thus limiting the position of the insert 9.

[0036] A reinforcing base 11 is fixedly mounted on the surface of the laser surface polisher 44, and one side of the reinforcing base 11 is fixedly mounted on the surface of the drive base 43 by threads.

[0037] It is worth noting that, such as Figure 3 As shown, the reinforcement base 11 is set to firmly install the coating laser on the surface of the drive base 43 to prevent it from falling off.

[0038] It also includes a drive unit 12 for rotating the tray 3. The drive unit 12 includes a second motor 121 embedded inside the base 1. The output end of the second motor 121 is connected to the axis at the bottom of the tray 3. Several sliding seats 122 are installed at the bottom of the tray 3. The bottom of the several sliding seats 122 is in contact with the top of the base 1.

[0039] It should be noted that, as Figure 5 As shown, the second motor 121 is started to drive the tray 3 to rotate, and rotate the bar body to one side of the starter 16. Multiple bar bodies on the top of the tray 3 are rotated to the polishing area. The second motor 121 is a stepper motor.

[0040] The top of the base 1 is provided with an annular groove 13 for guiding the movement of several sliding seats 122;

[0041] Furthermore, such as Figure 5 As shown, the rotation of the tray 3 will cause several sliding seats 122 at its bottom to rotate within the annular groove 13, providing support for the rotation of the tray 3.

[0042] The base 1 has a groove 14 inside, and a push block 15 is slidably installed inside the groove 14. A starter 16 for rotating the bar body is fixedly installed on the top of the push block 15. A cylinder 17 for moving the push block 15 is embedded in one side of the base 1.

[0043] It is worth noting that, such as Figure 5 As shown, the starting cylinder 17 drives the push block 15 to slide in the groove 14. The starter 16 is installed on the top of the groove 14. The top of the starter 16 contacts the wheel and fits against the bar body. When the starter 16 is working, the bar body is driven to rotate.

[0044] The bottom of the tank 14 is connected to a drain 18;

[0045] Specifically, such as Figure 5 As shown, the trough 18 is connected to the tank body 14 to prevent debris from accumulating in the tank body 14.

[0046] Fans 19 are hinged to both sides of the bottom of the top plate 2. Electric push rods 20 are hinged to one side of each of the two fans 19. The tops of the two electric push rods 20 are hinged to the bottom of the top plate 2.

[0047] like Figure 4 As shown, the fan 19 can be activated to cool the surface of the polished bar body and also has a dust removal function. The electric push rod 20 can drive the fan 19 to adjust its angle, thereby increasing the air blowing range.

[0048] This device inserts the rod body to be polished into the insert 9. Multiple rods can be inserted into the tray 3. The second motor 121 is started to rotate the tray 3, rotating the rod body to one side of the starter 16. The rotation of the tray 3 causes several sliding seats 122 at its bottom to rotate within the annular groove 13, providing support for the rotation of the tray 3. The starting cylinder 17 drives the push block 15 to move, so that the top contact wheel of the starter 16 is in contact with the surface of the rod body. The rotation of the top contact wheel of the starter 16 drives the rod body to rotate, and the bottom of the rod body inserts into the insert 9. It will rotate within the mounting base 8, start the first motor 45 to drive the threaded rod 42 to rotate, control the drive base 43 to slide vertically on the mounting frame 41, wherein a laser surface polisher 44 is installed on one side of the drive base 43, the laser surface polisher 44 polishes the surface of the bar body, as the bar body rotates and the height of the laser surface polisher 44 is adjusted, polishing the set length area of ​​the bar body. After processing is completed, the tray 3 rotates, transferring the processed bar to the next receiving station, and the new bar is transferred to the processing position, thus completing one cycle.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
