Description

Technical Field

[0001] This utility model belongs to the field of stern shaft bearing processing technology, and specifically relates to a vibration-damping tool holder mechanism for turning the outer diameter of a stern shaft bearing. Background Technology

[0002] Stern shaft bearings are key components in marine propulsion systems. They are installed at the stern of the ship to support the stern shaft, ensure its normal operation, and transmit the power of the main engine to the propeller. They play a vital role in the ship's sailing performance and reliability. A tool holder mechanism is required during the machining of the outer diameter of the stern shaft bearing.

[0003] Existing tool holder mechanisms typically utilize a drive device to rotate the bearing, allowing the tool to contact the surface of the bearing's outer ring and complete the turning of the bearing's outer diameter. However, in actual use, the following problems exist: due to the high precision requirements of turning, different tools need to be changed during the turning of the bearing's outer diameter, which increases the workload of the operator. To address these issues, we propose a vibration-damping tool holder mechanism for turning the outer diameter of stern shaft bearings. Utility Model Content

[0030] Furthermore, a first bearing is welded to the center of the bottom of the inner cavity of the base 1, and the surface of the rotating rod 2 is rotatably connected to the inner cavity of the first bearing. Through the first bearing, the rotational stability of the rotating rod 2 is improved.

[0031] Furthermore, a second bearing is welded at the center of the top of the inner cavity of the base 1 and extending to the outside of the base 1. The bottom of the top seat 11 is rotatably connected to the surface of the second bearing. The second bearing improves the rotational stability of the top seat 11.

[0032] Brief description of the usage process: The servo motor 5 drives the rotating rod 7 to rotate, which in turn drives the first pulley 6 to rotate, which in turn drives the belt body 4 to rotate, which in turn drives the second pulley 3 to rotate, which in turn drives the rotating rod 2 to rotate, which in turn drives the top seat 11 to rotate, which in turn drives the housing 9 and the cutting tool 8 to rotate. Users can choose different models of cutting tools 8 according to their own needs.

[0033] Example 2:

[0034] refer to Figure 1-3 A vibration-damping tool holder mechanism for turning the outer diameter of a stern shaft bearing includes a fixed block 15 welded to the center of the bottom of the inner cavity of a top seat 11. A first electric push rod 14 is bolted to all four sides of the fixed block 15. A sliding plate 12 is bolted to one side of the first electric push rod 14. A push rod 13 is bolted to one side of the sliding plate 12. One side of the push rod 13 is bolted to the back of the mounting plate 10.

[0035] Furthermore, a groove is provided at the bottom of the inner cavity of the top seat 11, and the bottom of the sliding plate 12 is slidably connected to the inner cavity of the groove. The groove improves the stability of the sliding plate 12.

[0037] Brief description of usage: When it is necessary to change the tool 8, the user starts the servo motor 5 through the external controller. The servo motor 5 drives the rotating rod 7 to rotate, which in turn drives the first pulley 6 to rotate. The first pulley 6 drives the belt body 4 to rotate, which in turn drives the second pulley 3 to rotate. The second pulley 3 drives the rotating rod 2 to rotate, which in turn drives the top seat 11 to rotate. The top seat 11 then drives the housing 9 and the tool 8 to rotate. The user can select different models of tool 8 according to their needs. When it is necessary to adjust the lateral angle of the tool 8, the user starts the first electric push rod 14 through the external controller. The first electric push rod 14 pushes the sliding plate 12 to move, which in turn pushes the push rod 13 to move. The push rod 13 then moves the housing 9 and the cutting tool 8 to the designated position. Since the first electric push rod 14 consists of four belt bodies, each controlled independently, the user can activate the corresponding first electric push rod 14 according to their needs and the type of cutting tool 8 required. Finally, the user can activate the second electric push rod 16 via an external controller. The second electric push rod 16 pushes the moving plate 17 to move, which in turn pushes the cutting tool 8 to move. The cutting tool 8 then moves to fit against the surface of the workpiece, allowing for turning of the rotating workpiece.
