Detailed description of the invention
Detailed description of the invention is further described below in conjunction with accompanying drawing and technical scheme:
Large-scale marine propeller is the important parts of shipping industry, has the features such as complex-shaped, not of uniform size.When clamping is carried out to large-scale marine propeller, first marine propeller should be placed in medial support mechanisms III, then with according to treating that the geomery of clamping marine propeller carries out the adjustment of jaw position, finally utilize motor pushing claw to be clamped by marine propeller.
A kind of marine propeller flexible fixture described in the present embodiment is used for carrying out clamping to large-scale change number of blade marine propeller.Such as clamping three leaf oar, clamping process is as follows: flexible fixture base 1 is installed on machine tool rotary working table, and fixing; Screw is arranged on flexible fixture, and coaxial with it; 4 bearing plates 3 and medial support mechanisms III complete the support to screw jointly.According to the spacing between propeller blade, adjust four revolution clamping devices II respectively relative to the angle position of base apparatus I at circumferencial direction by four gyration servomotors 23, claw 7 is not interfered with the blade of marine propeller.Clipper disk brake 5 and frictional disk 2 locking, make revolution clamping device II fix at circumferencial direction; High-power rectilinear motion servomotor 14 in each group of revolution clamping device II drives trapezoidal screw 10 to rotate, and then promotion claw 7 moves, until the propeller hub of marine propeller is clamped, by the torque-feedback of linear drives servomotor 14, system can learn chucking power size, and after chucking power arrives setting, linear drives servomotor 14 halts, this completes the clamping to marine propeller, as shown in accompanying drawing 1,2,3.At accompanying drawing 1, in 2, small arc-shaped guide rail slide block 16 and orthodrome guide rail slide block 29 are fixedly mounted on the bottom turning round clamping device body 8, respectively with small arc-shaped circular guideway 27, orthodrome circular guideway 6 matches, small arc-shaped guide rail slide block 16 and orthodrome guide rail slide block 29 can do gyration on small arc-shaped circular guideway 27 and orthodrome circular guideway 6, and orthodrome circular guideway 6 and small arc-shaped circular guideway 27 are fixedly mounted on flexible fixture base 1 respectively, like this, revolution clamping device II just can do gyration around axis on base apparatus I, and then adjustment claw axial angle on base apparatus I, the mode driving revolution clamping device II to do gyration is: gyration decelerator mount pad 21 is fixedly mounted on revolution clamping device body 8, gyration decelerator 22 is fixedly mounted on gyration decelerator mount pad 21, gyration servomotor 23 output and gyration decelerator 22 input coaxially fixedly mount, gyration decelerator 22 output coaxially fixedly mounts with revolution pinion 20, revolution pinion 20 is meshed with the revolution gear wheel 4 be fixedly mounted on base apparatus I, when gyration servomotor 23 Driving Torque, revolution clamping device II just can be driven to do gyration around axis.
When the marine propeller of clamping four leaf oar, five leaves or more number of blade, only need adjust four revolution clamping devices II respectively relative to the angle position of base apparatus I at circumferencial direction by four gyration servomotors 23, recycling aforesaid way can realize clamping.
A kind of marine propeller flexible fixture of the present invention highly versatile, multiple big-and-middle-sized marine propeller can be clamped, avoid the situation designing a special fixture for each marine propeller, can effectively shorten marine propeller production cost and process-cycle, there is higher technology content and social economic value.
