Abstract
The utility model relates to a crankshaft turning device. A main body consists of a platform and two symmetrical supports arranged at the front end of the platform; and the crankshaft turning device is characterized in that: a flange is arranged between the two symmetrical supports, is connected with the front end of the platform through a couple axle, and has a regular octagon shape; two opposite sides on the upper part of the flange are provided with positioning holes; two opposite sides on the lower part of the flange are provided with positioning frames; the middle of the flange is provided with at least three soft positioning blocks which are distributed in the middle of the flange in a circular array; filling wood blocks are arranged in the positioning frames; and wedged wood blocks are arranged on the front of the upper ends of the filling wood blocks. By the structure, when a crankshaft is turned, the crankshaft is hoisted to the flange and fixed by the positioning frames, and a crankshaft journal is prevented from being scratched by matching the filling wood blocks with the wedged wood blocks; the array distribution of the soft positioning blocks ensures the stable fixation of the crankshaft; and the crankshaft is turned and rotated under the drive of the couple axle. The crankshaft turning device is simple in structure, safe in operation and suitable for turning large pieces in machining.
Description
Technical field:
The utility model relates to a kind of tipping arrangement, especially relates to the turning device of big part bent axle in a kind of boats and ships processing industry.
Background technology:
In the spot ship industry, the processing of engine crankshaft design is particularly important, and it is the power resources of ship's navigation, and wherein, crank throw, trunnion and the two axial ends of forming two-stroke marine low speed diesel engine bent axle need be carried out fit after the hot jacket heating technique.Adopt vertical cover mode to operate during bent axle bearing hot jacket.After hot jacket finished, bent axle was in vertical state.And bearing needs horizontal positioned when carrying out fine finishining on lathe.But should the common weight of series two-stroke low speed machine crankshaft all at tens tons of weights, so bent axle to stand up handling be not that simple manually upset just can be finished.Adopt and simple fix upset, can make to produce cut on the bent axle or cause other dangerous or damages by mechanical component, and because the weight of bent axle own, general mechanical component can't support, and can have certain danger.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of simple to operate, the bent axle equipment for supporting patient with burn of bent axle safety when guaranteeing to stand up.
The technical scheme in the invention for solving the technical problem is: a kind of bent axle turning device, main body is a platform and the two symmetrical supports that are arranged on the platform front end, in the middle of two symmetrical supports, be provided with a flange, flange is connected with the platform front end by universal driving shaft, described flange is an octagon, two corresponding sides places on flange top offer locating hole, and two corresponding sides places of flange bottom are provided with locating rack, and locating rack is connected on the flange by bolt.
In order to guarantee that bent axle avoids scratching in switching process, and fixed crankshaft, do not allow it slide, reduce the danger of its single unit system, the centre of flange is provided with soft locating piece, and the number of soft locating piece is at least three, circular array distribution in the middle of flange.
In order to prevent the slip of axle journal in the bent axle, be provided with the filling wooden unit in the described locating rack, the front portion of filling the wooden unit upper end is provided with a bolt.Crankshaft journal is stuck in the bolt.
In order to strengthen the steadiness of its fixed crankshaft, the locating rack back is provided with reinforcement, and described reinforcement is at least three.
After adopting said structure, be characterized in: this structure to flange, is fixed the bent axle handling when the upset bent axle with locating rack, fills being used of wooden unit and bolt and guarantees that crankshaft journal avoids scratching; The array distribution of soft locating piece guarantees the steady of bent axle; Finish the rotation of standing up of bent axle by the driving of universal driving shaft.Simple in structure, handling safety is fit to the upset of big part in the machining.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
