The specific embodiment
Below in conjunction with accompanying drawing and technical scheme, further describe the specific embodiment:
Large-scale marine propeller is the important parts of shipping industry, has the features such as complex-shaped, not of uniform size.When large-scale marine propeller is carried out to clamping, should first marine propeller be placed in medial support mechanisms, then with according to treating that the geomery of clamping marine propeller carries out the adjustment of claw position, finally utilize motor pushing claw that marine propeller is clamped.
Described in the present embodiment, a kind of marine propeller flexible fixture is for carrying out clamping to large-scale change number of blade marine propeller.Clamping three leaf oars for example, clamping process is as follows: clamp 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 complete the support to screw jointly with medial support mechanisms IV.According to the spacing between propeller blade, by four gyration servomotors 23 adjust respectively four revolution clamping device II with respect to base apparatus I the angle position at circumferencial direction, claw 7 is not interfered with the blade of marine propeller.Clipper disk brake 5 and frictional disk 2 lockings, make to turn round clamping device II and fix at circumferencial direction; High-power rectilinear motion servomotor 14 in each group revolution clamping device II drives trapezoidal screw 10 rotations, 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 be learnt chucking power size, and after chucking power arrives setting, linear drives servomotor 14 halts, so just completed 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 is fixedly mounted on orthodrome guide rail slide block 19 bottom of 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 19 can be done gyration on small arc-shaped circular guideway 27 and orthodrome circular guideway 6, and orthodrome circular guideway 6 is fixedly mounted on respectively on flexible fixture base 1 with small arc-shaped circular guideway 27, like this, revolution clamping device II just can be done gyration around axis on base apparatus I, and then adjustment claw axial angle on base apparatus I, the mode that drives 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 outputs and gyration decelerator 22 inputs coaxially fixedly mount, gyration decelerator 22 outputs coaxially fixedly mount with revolution pinion 20, revolution pinion 20 is meshed with the revolution gear wheel 4 being fixedly mounted on base apparatus I, when the 23 output torque of gyration servomotor, just can drive revolution clamping device II to do gyration around axis.
When the marine propeller of clamping four leaf oars, five leaves or more number of blade, only need by four gyration servomotors 23 adjust respectively four revolution clamping device II with respect to base apparatus I the angle position at circumferencial direction, recycling aforesaid way can be realized clamping.
A kind of marine propeller flexible fixture of the present invention highly versatile, can clamp multiple big-and-middle-sized marine propeller, avoided the situation for a special fixture of each marine propeller design, can effectively shorten marine propeller production cost and process-cycle, there is higher technology content and social economic value.
