Description

Technical Field

[0001] This utility model belongs to the technical field of surface treatment devices, specifically relating to a surface treatment device for manufacturing large slewing bearing forgings. Background Technology

[0002] In the manufacturing process of large slewing bearing forgings, surface treatment is crucial to meeting stringent quality standards and ensuring superior product performance. Grinding equipment, as the core equipment in this process, effectively eliminates surface roughness and defects through precise grinding operations, improving surface smoothness and gloss. This lays a solid foundation for subsequent assembly and use, ensuring that the surface smoothness of large slewing bearing forgings meets production requirements. However, currently available surface treatment equipment has significant shortcomings. After grinding, the overall structure of these devices is relatively fixed, lacking flexible folding designs between components. This prevents the equipment from being folded or compactly stored when not in use. Consequently, the equipment still occupies a significant amount of production workshop space, reducing its practicality. Utility Model Content

[0003] The purpose of this invention is to provide a surface treatment device for manufacturing large slewing bearing forgings, aiming to address the significant shortcomings of existing surface treatment devices commonly found on the market. After grinding, these devices have a relatively fixed overall structure, lacking flexible folding designs between components, and cannot be reasonably folded or compactly stored when not in use. This results in the equipment still occupying a significant amount of production workshop space and reducing its practicality even when not in use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for manufacturing large slewing bearing forgings, comprising a support, a recessed block connected to the top of the support, an installation plate disposed inside the recessed block, a three-jaw chuck disposed at the front end of the installation plate, a drive motor disposed at the back end of the installation plate, a support block disposed at the top of the support, a fixing block being connected through the surface of the support block, a pressing bolt being threaded through the top of the support block, a servo motor being connected to the front end of the fixing block, a grinding disc disposed at the back end of the fixing block, a rotating shaft being rotatably connected inside the recessed block, a first gear being fixedly connected to one end of the rotating shaft, a first motor being mounted at the back end of the recessed block, a second gear being connected to the output shaft of the first motor, and two rectangular blocks being symmetrically mounted at the top of the recessed block, with fixing bolts threaded through the surface of the rectangular blocks.

[0010] As a preferred embodiment of the surface treatment device for manufacturing large slewing bearing forgings according to this utility model, the support block can form a reciprocating threaded motion with the threaded rod through the threaded sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By coordinating the rotating shaft, the first gear, the first motor, and the second gear, the angle of the mounting plate can be adjusted, thereby making the mounting plate parallel to the support.

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-4 This utility model provides the following technical solution: a surface treatment device for manufacturing large slewing bearing forgings, including a support 1, a recess 2 connected to the top of the support 1, an installation plate 3 inside the recess 2, a three-jaw chuck 4 at the front end of the installation plate 3, a drive motor 5 installed at the back end of the installation plate 3, a support block 6 at the top of the support 1, a fixing block 7 penetratingly connected to the surface of the support block 6, a pressing bolt 10 threadedly connected to the top of the support block 6, a servo motor 8 connected to the front end of the fixing block 7, a grinding disc 9 at the back end of the fixing block 7, a rotating shaft 11 rotatably connected inside the recess 2, a first gear 12 fixedly connected to one end of the rotating shaft 11, a first motor 13 installed at the back end of the recess 2, a second gear 14 connected to the output shaft of the first motor 13, and two rectangular blocks 15 symmetrically installed at the top of the recess 2, with fixing bolts 16 threadedly connected to the surface of the rectangular blocks 15.

[0022] In practical use, the three-jaw chuck 4 can connect to a large slewing bearing forging. The three-jaw chuck 4 is then connected to the output shaft of the drive motor 5. Starting the drive motor 5 rotates the three-jaw chuck 4, causing the large slewing bearing forging, which is fixed to the three-jaw chuck 4, to rotate synchronously. The size of the large slewing bearing forging ranges from 40cm to 2m. Subsequently, the grinding disc 9 can be used to grind the surface of the large slewing bearing forging. The grinding disc 9 is connected to the output shaft of the servo motor 8, which drives the grinding disc 9 to rotate. The cooperation between these two components allows for the treatment of the surface of the large slewing bearing forging, achieving all-around grinding.

[0023] Preferably, the rotating shaft 11 is fixedly connected to the mounting plate 3, and the mounting plate 3 can be rotatably connected to the recess 2 through the rotating shaft 11.

[0024] In practical use, the mounting plate 3 is fixedly connected to the rotating shaft 11. When the mounting plate 3 is subjected to external force and begins to rotate, the rotating shaft 11 rotates synchronously inside the recess 2. Because the mounting plate 3 is firmly connected to the rotating shaft 11, it does not simply rotate freely along the surface of the rotating shaft 11, effectively ensuring the stability and synchronicity of the rotation. This structural design lays the foundation for the smooth engagement and linkage of the first gear 12 and the second gear 14.

[0025] Preferably, the tooth pitches of the first gear 12 and the second gear 14 mesh.

[0026] In practical use, when the first motor 13 is powered on and started, its output shaft, through its own rotational power, directly drives the second gear 14, which is closely connected to it, to rotate around the shaft. Since the second gear 14 meshes with the first gear 12, during the rotation of the second gear 14, the rotational force is precisely transmitted to the first gear 12 through continuous and stable meshing between the teeth, causing the first gear 12 to rotate synchronously. The first gear 12 is fixedly connected to the rotating shaft 11, so the rotation of the first gear 12 synchronously drives the rotating shaft 11 to rotate as well, thereby enabling efficient and orderly linkage of all components in the entire mechanical structure.

[0027] Preferably, the mounting plate 3 can be detachably and fixedly connected to the recess 2 by fixing bolts 16.

[0028] In practical use, the fixing bolt 16 passes through the pre-drilled through hole on the rectangular block 15 and then screws into the corresponding screw hole on the mounting plate 3. This tight connection effectively enhances the stability between the rectangular block 15 and the mounting plate 3. When the large slewing bearing forging is firmly fixed to the front end of the mounting plate 3 by the three-jaw chuck 4, the fit between the mounting plate 3 and the recess 2 is also reliably guaranteed, preventing displacement or loosening due to external forces such as vibration and impact generated during forging processing. At the same time, this stable connection significantly reduces unnecessary shaking and wobbling of the first gear 12 and the second gear 14 during transmission, thereby reducing frictional loss on the gear tooth surfaces, extending gear service life, ensuring the stability and reliability of the entire transmission system, and ultimately ensuring the smooth progress of the large slewing bearing forging processing.

[0029] Preferably, a threaded rod 17 is installed inside the support 1, a guide rod 19 is installed inside the support 1, and a threaded sleeve 18 is threadedly connected to the surface of the threaded rod 17.

[0030] In practical use, the threaded sleeve 18 has an opening on its surface that matches the guide rod 19. The threaded sleeve 18 is then fitted onto the surface of the guide rod 19 and subsequently threaded onto the surface of the threaded rod 17. When the threaded rod 17 rotates, the threaded sleeve 18, whose circumferential rotational freedom is restricted by the guide rod 19, cannot rotate with the threaded rod 17. Instead, it can only move stably and precisely along the threaded trajectory on the surface of the threaded rod 17 through the interaction of its internal threads and the external threads of the threaded rod 17. This ensures the stability and accuracy of the threaded sleeve 18 during movement.

[0031] Preferably, the threaded sleeve 18 is connected to the support block 6, and the threaded rod 17 can be rotatably connected to the support 1 through the bearing.

[0032] In actual use, when the threaded rod 17 is manually rotated, it will rotate stably along the inner ring of the bearing, thereby ensuring the smoothness and stability of the rotation of the threaded rod 17.

[0033] Preferably, the support block 6 can form a reciprocating threaded motion with the threaded rod 17 through the threaded sleeve 18.

[0034] In practical use, when the threaded sleeve 18 moves with the threaded rod 17, since the threaded sleeve 18 is connected to the support block 6, it can drive the support block 6 to move together. In this way, the movement of the support block 6 will drive the fixed block 7 and the grinding disc 9 set at the back end of the fixed block 7 to approach the surface of the large slewing bearing forging.

[0035] Working principle: The large slewing bearing forging is manually fixed using a three-jaw chuck 4. Then, the threaded rod 17 is rotated, causing its threaded sleeve 18 to move along the threads on the surface of the threaded rod 17. Simultaneously, the threaded sleeve 18 moves on the surface of the guide rod 19. The movement of the threaded sleeve 18 then brings the support block 6 closer to the surface of the large slewing bearing forging until the grinding disc 9 is in contact with the surface of the large slewing bearing forging. If the grinding disc 9 is not in contact with the surface of the large slewing bearing forging, the clamping bolt 10 is manually rotated to release the fixing block 7. Then, the position of the fixing block 7 is adjusted so that it brings the grinding disc 9 into contact with the surface of the large slewing bearing forging. Finally, the clamping bolt 10 is rotated again to fix the fixing block 7. This coordination improves the applicability of the surface treatment device. Next, the drive motor 5 and servo motor 8 are started. At this time, the three-jaw chuck 4 drives the large slewing bearing forging to rotate, and the grinding disc 9 begins to rotate. The coordination between these two components treats the surface of the large slewing bearing forging, achieving all-around surface grinding. After using the surface treatment device, the fixing bolts 16 are manually unscrewed to release the mounting plate 3. Then, the power supply is connected to start the first motor 13. The output shaft of the first motor 13 drives the second gear 14 to rotate, which in turn drives the first gear 12 to rotate. Simultaneously, the first gear 12 drives the rotating shaft 11 to rotate, which in turn drives the mounting plate 3 to rotate until the mounting plate 3 is parallel to the support 1. The operation of the first motor 13 is then stopped. In this way, when the surface treatment device for manufacturing large slewing bearing forgings is not used, it is easy to perform folding operations, effectively reducing the footprint of the surface treatment device and improving its practicality.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
