Description

Rotary platform for marine shell machining Technical Field The utility model belongs to the field of processing platforms, and particularly relates to a rotary platform for processing an end face shell of a marine propeller. Background The shell of marine engineering propeller terminal surface is the hemisphere, needs to cut out structures such as water conservancy diversion slot hole on its side, originally places the propeller shell on fixed workbench, and personnel encircle to walk to carry out cutting process to the propeller shell, and the present is through cutting the machine hand to process the propeller shell to improve machining efficiency and precision. The cutting machine hand sets up by the workstation, and original fixed workstation can not satisfy the processing demand, needs a rotary worktable to adjust the processing position of propeller casing, and current rotary worktable is either complicated in structure or bearing capacity is poor, and large-scale propeller casing is placed on the workstation, and the workstation can take place to incline and make the machining precision reduce. Disclosure of utility model Based on the content in the background technology, the utility model provides the rotary platform which has a simple and exquisite structure and is not easy to incline and can be used for processing the marine shell. The provided rotary platform for processing the marine shell comprises a disc platform body, a supporting frame, a constant-height support, a supporting seat and a roller; The center department of disc stage body rotates through the bearing and connects on the support frame, still is provided with a plurality of contour supports in the below of disc stage body, and a plurality of contour supports are circumference arrangement and set up, rotate through the bearing on the top surface of contour support and be connected with the gyro wheel, the tread of gyro wheel can contact with the bottom surface of disc stage body, and this gyro wheel can carry out rolling support to it when the disc stage body rotates, can avoid the disc stage body to take place the slope because of the bearing, has guaranteed machining precision. Further, a plurality of locating holes are formed in the periphery of the disc table body, a limiting block is fixedly connected to the corresponding position of the supporting frame, a limiting pin hole is formed in the limiting block, a locating pin shaft can penetrate through the corresponding locating hole of the disc table body and then is arranged in the limiting pin hole of the limiting block, rotation of the disc table body is limited, the rotating angle of the disc table body is accurately adjusted through replacement of the locating hole, and machining precision of the propeller shell is further guaranteed. Preferably, the indexing between two adjacent positioning holes is 1 degree, and the indexing of the positioning holes enables the rotation angle adjustment of the disc table body to have higher precision. Preferably, at least one handle is fixedly connected to the periphery of the disc table body, and the handle is arranged vertically, so that an operator can push the disc table body to rotate through the handle. Through the technical scheme, the utility model at least comprises the following beneficial effects: The rotary platform disclosed by the application has a simple and exquisite structure, the hemispherical shell of the propeller is placed on the disc platform body, when the hemispherical shell is processed by a cutting machine hand at one side, the disc platform body can rotate to adjust the cutting station, so that the cutting machine hand is convenient for processing the periphery of the propeller shell, the equal-height support below the disc platform body and the design of the rollers can ensure that the disc platform body can be well supported in a rolling way during rotation, the disc platform body is prevented from tilting due to bearing, and the processing precision is ensured; In the further scheme, the matched design of the plurality of positioning holes, the limiting blocks and the positioning pin shafts on the disc table body enables the rotation angle of the disc table body to be precisely adjustable, and further ensures the machining precision of the propeller shell.
