Description

Technical Field

[0001] This utility model belongs to the field of processing platforms, specifically relating to a rotary platform that can be used for processing the end face shell of marine propulsion vehicles. Background Technology

[0002] The shell of the marine propeller end face is hemispherical, and structures such as guide holes need to be cut and processed on its side. Originally, the propeller shell was placed on a fixed workbench and personnel walked around it to cut and process the propeller shell. Now, a cutting robot is used to process the propeller shell to improve processing efficiency and accuracy.

[0003] The cutting robot is set up next to the worktable. The original fixed worktable can no longer meet the processing needs. A rotary worktable is needed to adjust the processing position of the pusher housing. Existing rotary worktables are either complex in structure or have poor load-bearing capacity. When a large pusher housing is placed on the worktable, the worktable will tilt, which will reduce the processing accuracy. Utility Model Content

[0004] Based on the content in the background art, this utility model provides a rotary platform with a simple and compact structure that is not prone to tilting and can be used for marine hull processing.

[0005] A rotary platform for processing marine hulls is provided, comprising a disc platform, a support frame, level supports, a support base, and rollers;

[0006] The center of the disc platform is rotatably connected to the support frame via a bearing. Multiple equal-height supports are also provided below the disc platform, arranged in a circle. Rollers are rotatably connected to the top surface of each equal-height support via a support seat. The wheel surface of the roller can contact the bottom surface of the disc platform. The roller can provide rolling support to the disc platform when it rotates, which can prevent the disc platform from tilting due to the load and ensure the processing accuracy.

[0007] Furthermore, multiple positioning holes are provided around the periphery of the disc platform, and a limiting block is fixedly connected to the support frame at the corresponding position. The limiting block has a limiting pin hole, and a positioning pin shaft can pass through the corresponding positioning hole of the disc platform and be placed in the limiting pin hole of the limiting block, thereby restricting the rotation of the disc platform. By changing the positioning hole, the rotation angle of the disc platform can be precisely adjusted, further ensuring the machining accuracy of the propeller housing.

[0008] Preferably, the graduation between two adjacent positioning holes is 1°, which allows for higher precision in adjusting the rotation angle of the disc platform.

[0009] Preferably, at least one handle is fixedly connected to the periphery of the disc platform. The handle is vertically arranged to facilitate the operator to rotate the disc platform by pushing it.

[0010] Through the above technical solutions, this utility model has at least the following beneficial effects:

[0011] The rotary platform described in this application has a simple and ingenious structure. The hemispherical shell of the pusher is placed on the disc platform. When the cutting robot arm is used for processing, the disc platform can rotate to adjust the cutting position, which makes it easy for the cutting robot arm to process the perimeter of the pusher shell. The design of the equal-height support and rollers under the disc platform ensures that the disc platform can also get good rolling support when rotating, preventing the disc platform from tilting due to the load and ensuring the processing accuracy.

[0012] In a further design, the combination of multiple positioning holes, limit blocks, and positioning pins on the disc platform allows for precise adjustment of the rotation angle of the disc platform, further ensuring the machining accuracy of the propeller housing. Attached Figure Description

[0019] The center of the disc platform 1 is rotatably connected to the support frame 2 via a bearing. Multiple equal-height supports 3 are also provided below the disc platform 1, arranged in a circular pattern. Rollers 5 are rotatably connected to the top surface of the equal-height supports 3 via support seats 4. The wheel surface of the rollers 5 can contact the bottom surface of the disc platform 1. The rollers 5 can provide rolling support to the disc platform 1 when it rotates, which can prevent the disc platform 1 from tilting due to the load and ensure the processing accuracy.

[0020] Multiple positioning holes 101 are provided around the periphery of the disc platform 1. Limiting blocks 6 are fixedly connected to the support frame 2 at corresponding positions. Each limiting block 6 has a limiting pin hole, allowing a positioning pin 7 to pass through the corresponding positioning hole 101 of the disc platform 1 and be positioned within the limiting pin hole of the limiting block 6, thereby restricting the rotation of the disc platform 1. By changing the positioning holes 101, the rotation angle of the disc platform 1 can be precisely adjusted, further ensuring the machining accuracy of the propeller housing. The graduation between two adjacent positioning holes 101 is 1°, which allows for higher precision in adjusting the rotation angle of the disc platform 1.

[0021] At least one handle 8 is fixedly connected to the periphery of the disc platform 1. The handle 8 is vertically arranged so that the operator can push the disc platform 1 to rotate through the handle 8.
