Technical Field

[0001] The utility model relates to the technical field of door surface processing and polishing production, in particular to a polishing device for automobile door production. Background Technique

[0002] A polishing device for automobile door production is a device specially used for the surface treatment of automobile doors, aiming to reduce the surface roughness of workpieces through mechanical, chemical or electrochemical means, so as to achieve a bright and flat effect.

[0003] The existing patent CN211805398U discloses a polishing device for door surface processing. A polishing device for door surface processing includes a device main body. A first motor is arranged on one side of the top of the device main body. A dust-proof shell is arranged on the outer surface of the first motor, and the output end of the first motor is connected with a first rotating shaft. The end of the first rotating shaft far away from the first motor is connected with a driving gear. This polishing device for door surface processing also has a baffle, a groove, a spring and a clamping plate. When the door is placed on the sieve plate, the user can pull the clamping plate to make the clamping plate slide upward through the groove and stretch the spring. When the door is placed well, the user can put down the clamping plate to make the spring reset and pull the clamping plate downward through the tension to fix and clamp the door, so as to avoid poor polishing quality of the door caused by unstable placement of the door during polishing and improve the polishing accuracy of the door.

[0004] This patent solves the problem that the outer surface of the door is arc-shaped, resulting in unstable fixing of the door and poor polishing quality. The above technical solution has the effect of stably fixing the door for precise polishing by setting the structure of the clamping plate, groove, spring and baffle. However, there is still a problem in the above solution that it cannot well adapt to doors of different sizes. Specifically, when using the clamping plate to clamp the door, since there are many different sizes of doors, and the shapes and arcs of the doors are also different, the clamping is not stable. During the polishing process, the door will shift, affecting the polishing effect. Therefore, the utility model proposes a polishing device for automobile door production.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0028] As Figure 1 and Figure 5 shown, this embodiment provides a technical solution: a polishing device for automobile door production, including a first support rod 1. It is characterized in that an adjusting assembly 2 is arranged on the side of the first support rod 1, and a clamping assembly 5 is arranged at the bottom of the adjusting assembly 2;

[0029] The clamping assembly 5 includes a sixth support plate 51. A second mounting block 52 is provided on the side of the sixth support plate 51. A first gear 53 is provided in the inner cavity of the second mounting block 52. A third gear 55 and a second gear 54 are provided on the side of the first gear 53. The first gear 53 meshes with the third gear 55, and the third gear 55 meshes with the second gear 54. A third connecting rod 57 is provided on the side of the third gear 55. A clamping jaw 56 is provided at one end of the third connecting rod 57 away from the third gear 55. A small motor is installed on the side of the first gear 53. When the motor is started, its output shaft rotates forward, thereby driving the first gear 53 to rotate. Due to the meshing effect between the gears, the rotation of the first gear 53 further drives the third gear 55 to rotate. The third gear 55 is meshed with the second gear 54, so the rotation of the third gear 55 also causes the second gear 54 to rotate accordingly. This series of gear transmissions are finally transmitted to the clamping jaw 56 through the third connecting rod 57, enabling the clamping jaw 56 to firmly clamp the car door, so as to ensure that the car door can be firmly fixed during the polishing process, prevent shaking or deviation, and thus guarantee the accuracy and efficiency of the polishing operation.

[0030] Further, as Figure 1 , Figure 2 and Figure 4As shown: The adjustment assembly 2 includes a bracket 21. On one side of the inner wall of the bracket 21, a first threaded rod 23 is provided. A first connecting rod 22 is threadedly sleeved on the surface of the first threaded rod 23. One end of the first connecting rod 22 away from the first threaded rod 23 is sleeved with a first sliding rod 26. On the top of the first connecting rod 22, a second threaded rod 24 is provided. A second connecting rod 25 is threadedly sleeved on the surface of the second threaded rod 24. One end of the second connecting rod 25 away from the second threaded rod 24 is sleeved with a second sliding rod 27. On the top of the second connecting rod 25, a first chute 28 is opened. On the top of the first connecting rod 22, a second chute 29 is opened. At the bottom of the clamping assembly 5, a moving assembly 4 is provided. The moving assembly 4 includes a second support plate 41. On the side of the second support plate 41, a second connecting block 42 is provided. On the side of the second connecting block 42 away from the second support plate 41, a third support plate 43 is provided. At the bottom of the third support plate 43, a fourth support plate 44 is provided. On the side of the fourth support plate 44, a third connecting block 45 is provided. Inside the cavity of the second connecting block 42, a second support rod 46 is provided. At the bottom of the second support rod 46, a fourth connecting block 47 is fixedly connected. On the side of the second support plate 41, a fourth chute 48 and a fifth chute 49 are opened. Inside the cavities of the fourth chute 48 and the fifth chute 49, rollers 410 are provided. One ends of the rollers 410 away from the second support plate 41 are respectively fixedly connected to the sides of the third connecting block 45 and the fourth connecting block 47. On the surface of the third support plate 43, a sixth chute 411 is opened. At the top of the fourth support plate 44, a fifth support plate 412 is fixedly connected. One end of the fifth support plate 412 extends into the cavity of the sixth chute 411 and is slidably connected to the cavity of the sixth chute 411. The polishing assembly 3 is installed at the intersecting position of the first chute 28 and the second chute 29. This layout allows it to move along two different planes. The first connecting rod 22 cooperates with the first threaded rod 23, enabling the polishing assembly 3 to be accurately positioned in the front-rear direction for polishing along the length direction of the car door. At the same time, through the coordinated work of the second threaded rod 24 and the second connecting rod 25, the position of the polishing assembly 3 in the left-right direction can be adjusted to meet the polishing requirements in the width direction of the car door. The first threaded rod 23 and the second threaded rod 24 cooperate, thus ensuring that the polishing assembly 3 can move freely in three-dimensional space and can then polish car doors of different sizes. One end of the second connecting block 42 is provided with a push rod. By starting the push rod, the second connecting block 42 can be pushed forward. When the second connecting block 42 moves forward, it can drive the third support plate 43 and the fourth support plate 44 to move forward. The shape of the fourth chute 48 is designed with a certain downhill slope. The fourth chute 48 and the rollers 410 cooperate, enabling the fourth support plate 44 to slide downward along the cavity of the fourth chute 48 while moving forward. Similarly, when the push rod pulls the second connecting block 42 backward,The fourth support plate 44 will move upward along the inner cavity of the fourth chute 48. At the same time, the fifth support plate 412 will also move upward along the inner cavity of the sixth chute 411. When the vehicle door is transported to the polishing area along with the third support plate 43, the fifth support plate 412 can lift the vehicle door from the bottom, creating conditions for the clamping assembly 5 to stably clamp the vehicle door, thus achieving the effects of precise positioning and stable clamping of the vehicle door, greatly improving the efficiency and quality of the polishing operation, and effectively preventing uneven polishing or surface damage caused by the shaking of the vehicle door.,

[0031] Due to the certain slope on the outer surface of the vehicle door, the polisher cannot polish its surface well. As Figure 3 shown: In this solution, a polishing assembly 3 is provided at the top of the second connecting rod 25. The polishing assembly 3 includes a first support plate 31. A first connecting block 32 is provided at the bottom of the first support plate 31. A telescopic rod 33 is provided at the bottom of the first connecting block 32. The bottom of the telescopic rod 33 is fixedly connected to a first mounting block 34. A half gear 36 is provided in the inner cavity of the first mounting block 34. An adjusting seat 35 is provided at the bottom of the half gear 36. A third chute 37 is opened at the bottom of the half gear 36. A first slider 38 is provided at the top of the adjusting seat 35. One end of the first slider 38 extends into the inner cavity of the third chute 37 and is slidably connected to the inner cavity of the third chute 37. The first support plate 31 is slidably connected to the top of the second connecting rod 25. A polisher is provided at the bottom of the adjusting seat 35. By adding the telescopic rod 33 at the bottom of the first support plate 31, the user can adjust the height of the polisher according to needs to adapt to vehicle doors of different sizes and models. The rack designs at the top and bottom of the third chute 37 and the adjusting seat 35 enable them to mesh with each other. Under this design, the small motor installed on the side of the third chute 37 can drive the third chute 37 to rotate through the forward rotation of its output shaft. As the third chute 37 rotates, the rack structure can drive the adjusting seat 35 to rotate accordingly. At this time, the cooperation between the first slider 38 and the third chute 37 restricts the movement track of the adjusting seat 35, ensuring that it will not deviate from the predetermined path during rotation, so as to achieve the effect of polishing different slopes on the surface of the vehicle door. This not only improves the flexibility and accuracy of the polishing work, but also greatly enhances the convenience of operation, thus being able to adapt to the polishing tasks of vehicle doors with various complex shapes.

[0032] Working principle:

[0033] As Figures 1 - 5 shown:

[0034] During use: First, drive the second connecting block 42 forward through the starting push rod. When the second connecting block 42 moves forward, it can push out the third support plate 43 and the fourth support plate 44. When the fourth support plate 44 moves forward, the roller 410 cooperates with the fourth chute 48, so that the fifth support plate 412 moves downward along the inner cavity of the sixth chute 411. After reaching the appropriate position, place the car door on the top of the third support plate 43. When the push rod retracts, the fourth support plate 44 moves upward along the inner cavity of the fourth chute 48, which can drive the fifth support plate 412 to move upward, and then can lift the car door. At this time, start the small motor on the side of the first gear 53, and the output shaft of the motor rotates forward, which can drive the third gear 55 and the second gear 54 to rotate, and then can make the jaws 56 clamp the car door to prevent it from shaking. After fixing the car door, start the small motor, which can drive the first threaded rod 23 and the second threaded rod 24 to rotate. Through the cooperation of the first threaded rod 23 and the first connecting rod 22, the front and rear positions of the polisher can be adjusted. Through the cooperation of the second threaded rod 24 and the second connecting rod 25, the left and right positions of the polisher can be adjusted. After adjusting the polisher to the appropriate position, lower the polisher through the telescopic rod 33 arranged at the bottom of the first support plate 31. Finally, adjust the polisher to the appropriate angle through the adjusting seat 35, so as to polish the surface of the car door.

[0035] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
